Description

Nasal clearing device.

The present invention relates to a device designed to administer and withdraw a washing fluid, loaded or not with substances, in the ENT sphere.

It is intended for hygiene, irrigation, treatment and care of the nasal cavities, and more particularly for clearing those of a young child or a disabled person by acting as a baby fly-irrigator.

The accumulation of phlegm in the nasal passages of a child is problematic because it prevents him from breathing normally (this is especially true for babies under one year old who cannot breathe through their mouth). In addition, their stagnation promotes bacterial proliferation with the risk of contamination extended to the entire ENT sphere (otitis for example).

The evacuation of phlegm in young children up to three years old, when they have generally acquired autonomy in the gesture of blowing their nose, can be carried out with a baby nasal aspirator. The treatment consists in generating a depression in a nostril in order to extract the mucus which hinders the respiratory flow.

There are different types of baby fly:

- the oral suction baby nasal aspirator, comprising a pipe connected to the mouth of the user, a nosepiece and a reservoir intended to collect the mucus extracted from the nostril under the effect of the user's suction. It may also include a filter to prevent the passage of mucus into the suction tube.

- the deformable bulb baby nasal aspirator. After deformation by the user, the return to position of an elastic element generates suction in order to extract mucus and collect it in a reservoir.

- the electric baby nasal aspirator which, by means of an electric pump, generates a vacuum to collect mucus in a reservoir.

These devices are widely used, however it must be recognized that in the event of severe obstruction or dry phlegm, the result is not always there. In addition, too frequent use of a suction device without moistening the nasal cavities leads to their irritation.

For this reason, aspiration into the nostril is often preceded by a spraying or instillation of physiological serum, which however requires successively introducing the tip of the bottle into each nostril, then the suction tip. , operations that take time and contribute to the nervousness of the child.

Many devices, such as the one described in document EP 1584 340 A1, allow the liquid to be sprayed and then sucked up through the same nozzle, but the operation must however be repeated on the second nostril. In addition, as the liquid is aspirated through the same nostril, it does not penetrate deeply into the nasal cavities, thereby reducing its impact on the evacuation of mucus.

Another method consists of first administering an appropriate liquid (physiological serum, sea water, etc.) into one nostril in order to soften the phlegm and, secondly, letting the liquid flow out the other nostril, or It is good to suck it in with a baby nasal aspirator, the child's head being kept tilted to the side to facilitate its evacuation and limit the penetration of liquid into the back of the throat. The treatment is repeated for the other nostril. However, if the care is badly done, the liquid can flow into the child's throat, which he does not really appreciate and makes the operation very difficult to repeat.

A much more effective variant consists of instilling liquid into a nostril and closing the child's mouth to force him to expel the air contained in the lungs through his nose and thus evacuate the liquid and mucus. Alas, this care is a little tricky to implement and it is therefore little practiced.

The administration of a liquid in one nostril and its aspiration by the other is a therapy recognized for its effectiveness.

This treatment is known as the "Proetz displacement method" and consists of administering the liquid into a first nostril with a pipette held in one hand and then withdrawing it into the second nostril through a source of electric suction held in the other hand and generally slaved to a foot control. The treatment requires a lot of precautions on the part of the user because it is essential, under penalty of serious trauma, to control the value of the depression applied in the ENT sphere of the patient. In addition, for the depression to be established, it is necessary for the patient to keep the soft palate sealed (for example by pronouncing the phoneme "KéKéKé"), thus isolating the nasopharynx from the throat. In fact, this method is not applicable to children under 4 years old, or to disabled people, unable to voluntarily seal their soft palate.

Various documents describe devices for irrigating both nostrils simultaneously.

Document GB 178630 describes an administration device comprising, connected to a common reservoir:

- A means of administration, connectable in a sealed manner to a nostril of the user and capable of containing a liquid and,

-A means of sampling, connectable in a sealed manner to the second nostril of the user,

- A means of entry connected to the mouth of the user.

With this device, the liquid solution is administered in one nostril by the action of the pressure delivered by the breath of the user, and its excess reaching the other nostril returns to the reservoir by the sampling means. Blowing automatically closes the soft palate, so the liquid does not pass into the throat. The device therefore operates without suction and in a closed circuit, which leads to obtaining a sampling flow rate identical to the administration flow rate and, moreover, subordinate to the latter.

However, it is impossible to apply such a device to a baby or a disabled person, since they are unable to blow voluntarily or close the soft palate.

Document CN 105853199 A describes a device comprising an administration means connected to a first nostril of a patient and a collection means connected to his second nostril.

The liquid is administered under pressure in the first nostril to be collected in a reservoir after passing through the nasal cavities. The device does not include a means of suction and like the device above, it cannot be used on a person unable to voluntarily close the soft palate.

Document US 1502163 A describes a device comprising:

- A means of administration, connectable in a sealed manner to a nostril of the user and capable of containing a liquid and,

- A sampling means, connectable in a sealed manner to the user's second nostril and to a suction bulb, a means capable of collecting the liquid coming from the nasal cavities.

It also comprises a shutter manipulated by the user and able to vent the means of administration. By activating the bulb, the user generates a depression in the sampling means which makes it possible to suck up the liquid present in the means of administration. The device therefore operates in a closed circuit, which leads to obtaining an administration flow rate identical to the suction flow rate and, moreover, subordinate to the latter.

In addition, the device needs to be in a vertical position to function properly, a position that is difficult to reconcile with pediatric care.

Document US 2010/0152653A1 describes a device comprising an administration means consisting of a reserve of liquid intended to flow by gravity into a first nostril of a patient and a sampling means comprising a suction means and intended to collect the liquid coming from his second nostril. However, the operator does not have the option of dissociating the liquid administration phase from the aspiration phase, nor that of manually adjusting the administration rate.

The document EP 2389918 filed in the name of the applicant as well as the patent FR 3016125 A1 describe a device administering a liquid in a first nostril while withdrawing it through the other thanks to the mobilization of a means of separation which can be constituted by the plunger of a syringe or by a deformable membrane. This device works in a closed circuit, without an external source of suction, which makes it possible, by a phenomenon of surface tension, to limit the penetration of liquid into the throat, in particular in children, on the condition, however, of having a seal. perfect at the level of the nostrils, which is not always easy to obtain if the child struggles. In addition, the administration of liquid is subordinated to a transfer of fluid in the collection means, which deprives the user of the possibility of administering the liquid and then of suspending the operation during the aspiration phase.

The applicant's approach was therefore to reconsider the traditional methods of nasal unblocking and to seek whether it would be possible to obtain a device making it possible to irrigate and extract mucus from both nasal cavities at the same time by allowing a user to control each of the flow rates independently, the two operations occurring simultaneously or offset in time, while avoiding the penetration of liquid into the back of the throat regardless of the position of the head of the recipient of the treatment, device operating with one hand, in particular so that it can be used by a single operator, who must at the same time ensure the maintenance of the beneficiary of the treatment.

This is what the invention proposes, using known means, namely:

- a means for administering washing fluid for nasal purposes comprising a reserve of washing fluid provided with a nasal administration nozzle,

- a sampling means comprising a collection reservoir intended for the collection of fluid and provided by one end with a sampling nosepiece intended to be connected to a nostril of a patient, and provided by the other end with a means suction.

The device according to the invention further comprises a connecting means designed to secure the administration means with the sampling means so as to produce a nasal clearing device arranged to provide support on the reserve accessible to at least one finger of the hand of an operator simultaneously with access to the suction means for at least one of the other fingers of this same hand or for the mouth of the said operator, a nasal clearing device configured for, when it is held and used by a single hand, independently of any other external support, and that the sampling nosepiece is positioned in a first nostril of the patient, on the one hand to administer, under the effect of a manual force exerted on the reserve by the operator , the lavage fluid into the patient's second nostril through the delivery nosepiece, whether or not simultaneously with the presence of suction established by the suction means in the sampling means, and configured to on the other hand to collect in the tank the washing fluid, loaded or not with bodily elements coming from the nasal cavities of the patient, the suction means being further configured to provide in the sampling circuit a suction whose flow, independent that corresponding to the administration of washing fluid, is controlled by the hand of the operator holding the nasal clearing device or by his mouth.

Thus, the user can, with one hand, carry out a complete care of the patient's nasal cavities while controlling the administration of washing fluid and its withdrawal, the two operations occurring simultaneously or not. With his free hand, he can, during the treatment, hold the patient, which often proves to be an essential condition in the case of a young child, because he does not appreciate the operation, and he shows by crying and gesticulating. One of the solutions used by practitioners consists in keeping the child's head on the side with the hand while the forearm immobilizes the body. It is almost impossible to carry out this type of treatment without firm support for the child. It is also interesting to be able to use the device regardless of the position of the patient's head, the treatment can thus be carried out indifferently in a lying or sitting position. The device, through simultaneous aspiration, prevents the penetration of liquid into the throat and therefore makes the operation less traumatic for the patient, thus facilitating its reiteration.

In an alternative embodiment, the device comprises a pipe and a mouthpiece so that the operator can generate oral suction. The device thus does not require any energy source other than that supplied by the user. In addition, oral suction is particularly well suited here because it makes it possible to generate a flow of air controlled by the operator, without manual action, with a high peak flow rate, while remaining within depression values that are not dangerous for the patient.

In another configuration, suction is provided by an electric pump. Thus the user is exempted from sucking into the device, the operation can sometimes be inconvenient. This configuration also makes it possible to carry out, in adults, operations to evacuate bodily elements, such as scabs, particularly in the case of post-surgical care.

In an alternative embodiment, the connecting means is configured to provide a removable and/or mobile mechanical connection between the administration means and the collection means. Thus, the device is able to allow the adjustment of the two aforementioned means and consequently that of the nasal prongs according to a variable and stable position to adapt to the nasal morphology of the patient and also to provide ergonomics such that it can be handled by a right- or left-handed user.

In a preferred embodiment of the invention, the device comprises at least one elastically deformable reserve by manual action, such as a pipette of the single-dose type initially filled with liquid. Thus, the liquid contained in the pipette is administered directly into the nostril, and a previously used pipette acts as a disposable collection reservoir.

In a variant embodiment, the means of administration consists of a nasal spray, with a manual pump or comprising a reserve of pressurized liquid. This configuration allows the use of an accessory already present on the market and capable of carrying out numerous liquid administrations without replacement intervention.

Other characteristics and advantages of the invention will emerge from the description which follows with reference to the appended drawing, schematically representing several embodiments, and in which:

In the description, the terms patient or beneficiary of the care designate the person to whom the care is provided. The terms operator or user designate the person providing the care, who can also perform the care for themselves.

The nasopharynx, from a fluidic point of view, can be schematized by a Y as illustrated in figure 1. The nostrils 1 and 2 serve as entrances to the nasal fossae 3 and 4, the latter joining in the cavum 5. The nasopharynx can be isolated from the mouth by closing the soft palate 6, which communicates with the back of the throat. The retrovelar space 7 corresponds to the diameter of the larynx.

Figure 2 illustrates the flow of fluid when administered through one nostril and withdrawn through the second, with the patient's soft palate sealed, typically by asking the patient to pronounce the phoneme “KéKéKé”. The liquid then passes through the two nasal fossae and because the connection to the nose is tight, it is necessary to control the flow rates applied to each nostril to prevent a pressure differential detrimental to the patient from being established in the ENT sphere.

Figure 3 illustrates fluid circulation when the soft palate is open. In order to prevent it from entering the throat, it is then necessary to apply suction with a flow rate greater than or equal to that of the liquid administered and such that it can generate a flow of air capable of entraining the said liquid and any phlegm outside the nasal cavities. This sampling rate is mainly a function of that of the administered liquid, of the passage diameter corresponding to the retrovelar space and of the air inlet present at the level of the administration nostril or that of the sampling in the event of absence of sealing. In the event of nasal obstruction, aspiration also makes it possible to generate a depression capable of freeing the congested passage. When liquid is administered in the form of fine droplets, the air flow entrains them according to the same principle. It is of course possible to collect the liquid outside the administration phase.

Figure 4 shows the device consisting of an administration means 100, a sampling means 200 and a connecting means 300.

The administration means 100 is constituted by an administration reserve 101, deformable by manual pressure and capable of containing a washing fluid 103, loaded or not with treatment substances, for example a liquid such as physiological saline or sea water, reserve 101 connected in its upper part to a nostril of the recipient of the treatment by an administration duct 102 fitted at its end with a nasal administration nozzle 110, preferably flexible and deformable. Reserve 101, advantageously made of viscoelastic material, comprises lateral bellows to facilitate its axial deformation.

The sampling means 200 comprises a collection reservoir 201 connected to the patient's other nostril via a sampling conduit 202 provided at its end with a sampling nasal tip 210, preferably flexible and deformable and capable of to be connected tightly. The collection tank 201 accommodates in its lower part a shutter 203 intended to provide a tight closure, the said shutter 203 comprising a suction conduit 204 capable of containing a filtration means 205, for example a cellular foam. A means of suction 220 allows the connection with the mouth of the operator or that of the beneficiary of the treatment. It consists of a connector 221 sealed at one end with the lower part of the suction duct 204, for example by clamping, and connected at the second end to a suction pipe 222 fitted with a mouthpiece 223.

The connecting means 300 provides an integral assembly of the administration means 100 and the sampling means 200, advantageously by a molded form uniting and immobilizing by adjustment the two ducts 102 and 202, so that when the nasal tip of sample 210 is positioned in a sealed manner in a first nostril, the position of the administration nozzle 110 is located at the entrance to the second nostril of a patient. Thus the distance between the longitudinal axes of two nosepieces 110 and 210 corresponds to the gap between the two nostrils of a patient, i.e., for example, a distance of between 8 and 20 mm. In order to facilitate the positioning of the nasal tips 110 and 210 in the patient's nostrils, the connecting means 300 comprises a bend, advantageously located at an equal distance between the ducts 102 and 202, to provide an angle α of inclination between the two axes longitudinal of the said nosepieces between 0° and 120°. The connecting means 300 makes it possible to ensure the position of two fingers (index and middle finger) while the thumb of the same hand is positioned on the bottom of the reserve 101.

After filling the reserve 101 with the appropriate washing fluid 103 and keeping the patient in a favorable position with his arm or his free hand in the case of pediatric use, the operator positions his other hand on the device, thumb on the bottom of the reserve 101, index and middle fingers on the connecting means 300, similar to the positioning of the fingers on a syringe. The mouthpiece 223 held between the lips, he then places the sampling nosepiece 210 in a sealed manner in one nostril of the patient as well as the administration nosepiece 110 in the other, without any other external support. By pushing on the reserve 101, the operator administers the washing fluid 103 into the corresponding nostril and, simultaneously or after having suspended its delivery, he sucks into the suction means 200 to collect the said washing fluid 103 in the collection reservoir 201, possibly loaded with mucus from the nasal cavities, without having to change the position of his fingers on the device. He can start the treatment again at his leisure without changing his position. He also has the possibility of precisely metering the flow rate and the quantity of washing fluid 103 administered by modulating the pressure exerted on the reserve 101, separately or simultaneously with suction, the flow of administration of the liquid being independent of that of aspiration. The operator also controls the suction flow through his mouth to adapt it to the treatment.

If the sampling flow is sufficient, the treatment is effective regardless of the position of the patient's head because by opposing the gravity of the washing fluid 103, it prevents it from entering the throat. Sustaining the suction after the administration phase makes it possible to evacuate the residual liquid corresponding to the volume of the nasal cavities.

A preferred embodiment is illustrated by FIG. 5 in which the means of administration 100 is a reserve of the single-dose pipette type, of a design which is moreover well known, forming both the reserve 101 and the nosepiece for administration 110, elastically deformable pipette by manual pressure and pre-filled in a sterile manner with the washing fluid 103 to be administered. The collection reservoir 201 also consists of a single-dose pipette, previously used and whose orifice has been enlarged, for example by cutting or by introducing a rod of greater diameter, in order to facilitate the passage of mucus. The suction duct 204 comprises a sealing means 208 able to perforate the bottom of the collection reservoir 201 (the single-dose pipette), like a trocar, and able to provide a sealed connection with the latter. The filtration means 205 is positioned in the suction duct 204, the latter being closed off by the shutter 203. The latter is a part resulting from plastic injection also comprising the connector 221 itself connected in a sealed manner to the pipe. suction 222 and the mouthpiece 223.

The connecting means 300, advantageously in one piece and made of viscoelastic material, comprises two holding elements 305, such as clamps or clips from molding, capable of providing a removable mechanical connection with each means 100, 200 in order to be able to put them in place or take them out while keeping them attached to said connecting means 300 during the treatment. The latter also comprises a stop element 306 configured to block the translation of the sampling means 200. It will be noted that the holding elements 305 are also designed to provide a mechanical connection ensuring mobility between the two means 100 and 200 in order to vary their respective position, and consequently those of the nosepieces, for example by sliding the reserve 101, while offering, by a sufficiently firm hold, the stability of the position once this has been obtained.

The operator uncaps the single-dose pipette constituting the reserve 101, inserts it into the connecting means 300, after having taken care to place a single-dose pipette, empty, on the suction conduit 204 in l pressing downwards so that its lower part is pierced by the sealing means 208. By controlled manual pressure on the reserve 101, it is able to administer the washing fluid 103 and to proceed with the treatment as described previously.

It will be noted that the device offers a support surface allowing the operator to hold and use the device only with two fingers of the same hand, for example by positioning them directly on the reserve 101.

He can also hold the device by positioning a finger on the connecting means 300, in this case one of the holding elements 305, and simultaneously press the reserve 101 with a second finger of the same hand. Thus, the connecting means 300 serves as a support for at least one finger of the operator when he exerts manual pressure on the reserve 101.

He can finally hold and operate the device by positioning the two fingers of the same hand on the holding element 305 ensuring the maintenance of the means of administration 100. Said holding element 305, by virtue of its elasticity, also allows to ensure the transfer of the manual force of the operator on the reserve 101.

FIG. 6 illustrates a configuration in which the administration reserve 101, such as a syringe body, allows the movement of a mobilization means 150 capable of generating the transfer of the washing fluid 103 into the administration means 100. The mobilization means 150 consists of a piston 155 integrally connected to a rod 152 sliding in a bearing 151 provided in the lower part of the reserve 101 for guiding purposes, said mobilization means 150 having, to be actuated, a manipulation element 153 intended to allow the support of the thumb.

A nozzle 104, such as a nozzle, capable of administering the washing fluid 103 in the form of a spray, droplets or fine jets, is positioned in the administration duct 102, advantageously near the administration nosepiece 110 .

It will be noted that several nozzles 104 can be arranged in the administration duct 102.

The means of administration 100 is therefore in the form of a syringe, advantageously pre-filled with the washing fluid 103.

The operator exerts manual pressure on the manipulation element 153 to administer the washing fluid 103 in the form of fine droplets and collect it, possibly in association with mucus.

Depending on the diameter of the nozzle 104, the mobilization means 150, identical to a syringe, makes it possible to suck the washing fluid 103 through the nasal administration nozzle 110, from an additional container. , and then deliver it to the patient. It thus makes it possible to establish the transfer of the washing fluid 103 into the administration means 100, either by aspiration or by administration.

FIG. 7 illustrates an embodiment in which the administration means 100 consists of a device capable of delivering the washing fluid 103 in the form of a spray, droplets or fine jets, such as a nasal spray. This can be of the mechanical type, as illustrated, that is to say comprising a mechanical pump actuated by manual pressure, or else be in the form of a pressurized reserve provided with a valve actuated by manual pressure. . These devices are of a design known elsewhere and in widespread use.

These therefore comprise an administration nosepiece 110, possibly a nozzle 104, and a reserve 101 filled with the washing fluid 103.

It should be noted that once initiated, the spray comprising a mechanical pumping system can deliver at least one puff, regardless of its orientation.

The connecting element 300 includes an orifice 307 able to allow the passage and maintain by adjustment the nosepiece for administration 110. The orifice 307 also allows the rotation of the connecting means 300 around the nosepiece for administration 110, and consequently the modification of the spatial position of the sampling means 200 with respect to that of the administration means 100, as well as that of the administration nosepiece 110 with respect to that of the sampling nosepiece 210, in order to be used indifferently by a right-handed or left-handed operator.

The connecting means 300 is configured to take on a shape and to keep it in order to modify and maintain the position of the two means 100 and 200, and consequently of the two nosepieces 110 and 210, relative to each other. To achieve this, it consists of a strip comprising two metal wires embedded in a viscoelastic material, the whole thus giving it shape memory. It has mechanical characteristics giving it the ability to be deformed by the user, manually and without the aid of tools, while maintaining the position thus obtained throughout the treatment.

After having deformed the connecting means 300 to his liking, the user positions the two means 100 and 200 and more particularly the two nosepieces 110 and 210 so that they adapt well to the patient's nostrils, and then he delivers a dose of washing fluid 103 in the form of droplets or fine jets by exerting pressure on the lower part of the nasal spray with at least one finger, for example with the thumb, while the middle finger and/or the index finger are in contact on the connecting means 300.

FIG. 8 illustrates a configuration in which the means of administration 100 is a nasal spray of the pressurized type, therefore able to contain the washing fluid 103 under pressure. The connecting means 300 consists of two holding elements 305, two clip-type clamps, assembled head to tail and intended to removably hold the administration means 100 through the nasal tip 110 and the sampling 200 through the collection tank 201. The two holding elements 305 advantageously form a single piece resulting from molding. Depending on whether he is right-handed or left-handed, the operator will position the sampling means 200 to the left or right of the administration means 100. The operator positions the reserve 101 in one hand and squeezes it between his palm and at least one finger, while placing another finger, still with the same hand, resting on the administration nosepiece 110. By exerting a manual force against these two support points, he administers washing fluid 103.

It will be noted that the connecting means 300 could in the same way be secured to the sampling nosepiece 210 by means of a first holding element 305, the second ensuring the maintenance of the administration nosepiece 110.

The connecting means 300 can also take the form of a single piece resulting from plastic injection including the two nosepieces 110 and 210.

FIG. 9 illustrates an alternative embodiment in which the suction is generated by a suction means 220 consisting of a body 228 housing an electric pump 224 powered by an energy source 229, such as batteries. The electric pump 224 comprises in its upper part a suction pipe 222 intended to be connected to the connector 221, the latter comprising an O-ring 224, to reinforce the seal. The electric pump 224 also includes a discharge channel 226, lateral, opening into the open air. A control element 227 allows the operator to start or stop the electric pump 224 by establishing or interrupting the electrical connection with the energy source 229. The suction means 220 is of a well-designed design. known, and advantageously, it corresponds to an electric baby fly pump able to generate a pneumatic depression, limited to -500 mb in order to avoid possible barotraumas.

The connecting means 300 is assembled integrally by any suitable fastening element on the upper part of the suction means 220. Advantageously, it forms an integral part of the body 228. administration 100 by the base of the reserve 101 and the sampling means 200 by means of the obturator 203, the assembly thus formed constituting a device held in one hand. The control element 227 is positioned so that it can be actuated by at least one finger of the user, for example the index or middle finger, while the thumb exerts pressure on the reserve 101. Thus, the user controls with his hand the suction flow that he can establish in the sampling means 200 at any time during the treatment, simultaneously or separately from the administration of liquid, the suction flow being independent of that of administration and vice versa .

It emerges from the foregoing that the device according to the invention is intended to facilitate the treatment, and more particularly the irrigation and extraction of mucus in a patient, by offering a single operator the possibility of providing complete care of the nasal cavities. It is particularly suitable when the soft palate cannot be closed voluntarily, for example for very young children or people who are not independent, as well as in the case of velopharyngeal insufficiency.

It also finds its place in the treatment of post-surgical care in adults by allowing the drainage of body elements, such as crusts resulting from the healing of wounds.
