technical field

The invention belongs to the field of devices, and relates to a breathing bag. This application is a divisional application of a patent application with an application date of December 14, 2020, application number 2020114638691, and the name of the invention is "breathing bag".

Background technique

Bronchial asthma is a heterogeneous disease in which chronic inflammation is associated with airway hyperresponsiveness, often with widespread and variable reversible expiratory airflow limitation leading to recurrent episodes of wheezing, shortness of breath, chest tightness, and/or ) symptoms such as cough, the intensity of which varies over time. More onset and exacerbation at night and (or) early morning. At the time of the onset of asthma, if the disease is mild, the patient can use Seretide, Symbicort and other drugs to inhale to control the asthma. In this case, the current treatment method is direct intravenous injection of drugs. Although the therapeutic effect of intravenous injection is remarkable, long-term intravenous injection will damage the blood vessels, harden the blood vessel wall and weaken its elasticity, thereby causing a series of vascular diseases; The way of medicine is too rapid, and the human body absorbs too much medicine at once, which will inevitably increase the load on the internal organs, and the adverse reactions of the human body to the medicine are also significantly amplified.

This application is made in order to solve the above-mentioned problems.

SUMMARY OF THE INVENTION

The purpose of the present invention is to address the above-mentioned problems in the prior art, and to provide a respiratory skin bag, which can adopt a non-intravenous injection treatment method in the case of a serious disease condition, improve the safety of treatment, and reduce the load on human internal organs, The adverse reactions are reduced, and the problems of poor treatment safety and high internal visceral load of the existing intravenous injection for asthma treatment are solved.

The object of the present invention can be realized through the following technical solutions:

A breathing bag, including a balloon, an installation tube, a safety valve, a duckbill valve, an exhalation valve and a vent, one end of the installation tube is connected to one end of the balloon, the safety valve, the duckbill valve and the exhalation valve Connected to the installation pipe, the exhalation valve has an air passage 1, which is characterized in that it also includes a treatment part 1, and the treatment part 1 includes a casing, and the casing has an air passage 2, so One end of the second air passage is an inlet, and the other end is an outlet. The inlet of the second air passage is communicated with the first air passage, and the outlet of the second air passage is communicated with the ventilation member. The housing also has a therapeutic drug, and when the duckbill valve is opened, the therapeutic drug can be discharged from the outlet along the airflow into the ventilator.

The breathing bag is a common tool in the field of medical breathing. In general, its purpose is to provide artificial ventilation and oxygen supply to patients without artificial airways, without spontaneous breathing, or with weak and irregular breathing and severe poor ventilation. , duckbill valve, balloon, oxygen storage valve, oxygen storage bag and oxygen catheter, the mask is connected to the exhalation valve, the oxygen storage bag is connected to the balloon, and the oxygen catheter is connected to the balloon and the oxygen source. Before the operation, it is necessary to inspect all parts of the breathing bag, then open the airway, remove foreign bodies in the oral cavity, then cover the patient's mouth and nose with the mask, and place the middle finger, ring finger and little finger of one hand on the patient's jaw to keep the patient's mouth open, index finger, Put the thumb on the mask (CE method), press it tightly without leakage, and squeeze the balloon with the right hand. After the balloon is squeezed, the oxygen enters the duckbill valve through the installation tube, and the one-way valve flap of the duckbill valve expands. Oxygen continues to enter the air passage one of the exhalation valve, then enters the mask, and finally enters the patient's body to achieve oxygen supply. When the patient's mouth is closed or the air passage is blocked, the oxygen can directly reverse the movement to open the air valve to achieve rapid deflation. Mounting pipes are used to mount various types of valves. The above is the basic operation process of the breathing bag, which will not be described in detail, and the installation methods and detailed structures of components such as duckbill valve, exhalation valve, safety valve, etc. will not be repeated, which are all in the prior art.

In this solution, the first treatment part is added in the breathing skin bag. After pressing the balloon, oxygen passes through the first and second air passages. It acts on the respiratory tract, so that the asthma symptoms can be quickly relieved, and the ventilator plays the role of ventilation conduction here. This program uses extrusion power to deliver the therapeutic drug into the patient's respiratory tract, and simulates the patient's oral inhalation operation through reverse injection, realizing a non-intravenous treatment method, which greatly improves the safety of treatment, reduces the load on the human body, and reduces adverse reactions. . At the same time, this external force injection method has sufficient oxygen power and rapid drug movement. Compared with active inhalation, it can make the drug reach the respiratory tract quickly, and the effect is quick. In addition, it also makes full use of the basic function of the breathing bladder to supply oxygen to the patient to help him quickly resume normal breathing. The concept is novel and ingenious.

In the above breathing bag, the ventilation member is a mask.

When the ventilator is a mask, the mask and the housing are plugged or tightly fitted, and can be disassembled at any time. In this scheme, the respiratory capsule plays two roles of oxygen supply and treatment. The oxygen supply function is not repeated here, but is the basic function. During treatment, the patient's mouth is opened, the mask is placed on the patient's face until it is airtight, and then the balloon is squeezed, and the therapeutic drug is driven by oxygen, transmitted to the patient's mouth through the mask, and finally reaches the respiratory area to achieve the therapeutic function. This regimen enables rapid treatment without additional manipulations.

In the above breathing bag, the ventilation member is a tracheal intubation tube, the inner end of the tracheal intubation tube extends into the patient's airway, and the outer end of the tracheal intubation tube is connected to the second outlet of the air passage.

In this scheme, the tracheal intubation tube is directly inserted into the patient's airway. During treatment, the outer end of the tracheal intubation tube is connected to the second outlet of the air passage (usually by a tight fit), and then the balloon is pressed. Entering the respiratory tract directly along the tracheal intubation can prevent the therapeutic drugs from acting on irrelevant parts such as the oral cavity, so that the therapeutic drugs can fully exert their effects, reduce the consumption of the therapeutic drugs, and have strong pertinence, and because other parts are not related to the therapeutic drugs. contact, so there are no side effects, and the safety performance is strong.

In the above-mentioned breathing bag, from the inside to the outside in the installation pipe are the duckbill valve, the exhalation valve and the treatment part 1 respectively.

Oxygen opens the duckbill valve, passes through the air passage 1 in the exhalation valve, and then passes through the air passage 2 in the treatment part 1. In this layout, when the patient's mouth is closed or the passage is blocked, due to the distance between the therapeutic drugs. The deflation flap is farther away, so oxygen is expelled directly from the deflation flap of the exhalation valve, without going through the therapy and taking it out of the deflation flap as well. On the contrary, if the treatment element is set between the duckbill valve and the exhalation valve, when the patient's mouth is closed or the channel is blocked, oxygen may pass through the treatment drug and take the treatment drug out of the abandonment valve, resulting in drug waste and leakage. hazard.

In the above breathing bag, the casing includes a left casing and a right casing that are both semi-cylindrical and can be fastened to each other, the left casing is provided with a channel 1, and the right casing is provided with a channel 2. , the sub-channel 1 and the sub-channel 2 constitute the air-passing channel 2.

The shell of the split structure is convenient for the replacement of therapeutic drugs.

In the above breathing bag, one end of the left casing and the right casing has an external thread, and one end of the air passage has an internal thread.

After the casing is assembled, one end of the casing is screwed into the second expired passage to realize the connection between the exhalation valve and the casing, thereby realizing the smooth flow between the first air passage and the second air passage.

In the above-mentioned breathing bag, the inner wall of the left casing has a plurality of buckling portions, and the inner wall of the right casing has a plurality of corresponding buckling grooves.

The detachable connection between the left casing and the right casing is realized through the arrangement of the buckle portion and the buckle groove. There are many other alternatives in practice.

In the above breathing bag, the buckling portion includes a cylindrical connecting column and a spherical buckling ball, the buckling groove is spherical, and one end of the connecting column is connected to the left housing, and the connecting The other end of the column is connected to the buckle ball, the diameter of the buckle groove is smaller than that of the buckle ball, and the buckle ball can enter the buckle groove.

The above structure realizes that the buckle ball enters the buckle groove by means of extrusion deformation, and the left shell and the right shell are connected by the reset of the buckle ball after being squeezed in. When separating the left casing and the right casing, break them apart so that the buckle ball can be deformed and separated from the buckle groove.

In the above-mentioned respiratory skin bag, the therapeutic drug is stored in the capsule, the capsule is fixed in the second air passage, and there is a flow gap between the capsule and the second air passage, and the capsule is pierced. After that, the therapeutic drug can flow out.

When the therapeutic drug in the capsule is used up, the shell can be opened to replace the capsule. After the capsule is pierced, a leak is formed, and the air flow takes away the therapeutic drug through the leak. This built-in capsule method can be used at any time, and the design is ingenious and convenient.

In the above-mentioned respiratory sac, the therapeutic drug is powder.

The powder does not flow freely like a liquid. The powder is light in weight and can quickly flow into the respiratory tract with the airflow, so that the effect is rapid and effective.

In the above breathing bag, the first treatment element further includes a fixing structure, the fixing structure includes a T-shaped connecting frame, the bottom end of the connecting frame is fixedly connected to the inner wall of the casing, and the two ends of the connecting frame are connected. There is an O-shaped clamp ring on the upper part, and the two ends of the capsule are respectively protruded into the two O-shaped clamps to realize axial fixation.

The inner diameter of the O-ring is smaller than the maximum outer diameter of the capsule. Therefore, when the two ends of the capsule are clamped into the two O-rings, the two ends of the capsule can be restricted, thereby preventing the capsule from moving axially and preventing it from being punctured and damaged. Due to the influence of airflow movement, the fixed structure has a stable fixing effect on the capsule.

In the above breathing bladder, the first treatment element further includes a piercing structure, the piercing structure includes a through hole opened on the casing, the through hole penetrates to the capsule, and the through hole penetrates to the capsule. The outer end of the hole is blocked by a stud.

In this solution, an external tool needs to be used to puncture the capsule. The method is to unscrew the stud and use a sharp object to pierce the capsule, and then reset the stud. This solution reduces the complexity of the treatment part 1 and simplifies the structure.

In the above breathing bladder, the first treatment element further includes a piercing structure, and the piercing structure includes a through-mounting hole opened on the casing, the through-mounting hole penetrates to the capsule, and the through-mounting hole is inserted into the capsule. A puncturing needle is connected in the hole, the inner end of the puncturing needle is a sharp end, the outer end of the puncturing needle is a pressing end, and the puncturing structure further comprises a spring sheathed outside the puncturing needle.

In this solution, the first treatment piece has its own piercing structure, only need to operate the pressing end to make the sharp end pierce the capsule, and automatically reset by the spring after releasing the hand. The piercing structure of this solution makes the piercing operation of the capsule convenient, The operation stability is strong, the phenomenon of slipping can be avoided, and both sides of the capsule can be pierced more smoothly, and the piercing is sufficient, so that the therapeutic drug can be fully discharged.

In the above breathing bag, the inner wall of the through-installation hole has a blocking edge, one end of the spring is fixedly connected to the blocking edge, and the other end of the spring is fixedly connected to the pressing end.

The puncture needle is connected with the through-mounting hole through a spring, one end of the spring is fixed on the baffle edge, and the other end of the spring is fixed on the pressing end, which can be realized by spot welding, tight fitting, etc.

A breathing bag, including a balloon, an installation tube, a safety valve, a duckbill valve, an exhalation valve and a vent, one end of the installation tube is connected to one end of the balloon, the safety valve, the duckbill valve and the exhalation valve Connected to the installation tube, the exhalation valve has an air passage 1, and it is characterized in that it also includes a treatment part 2, and the treatment part 2 contains a treatment drug. When the one-way valve of the duckbill valve When the valve is opened, the second treatment member is broken open and the therapeutic drug leaks from the second treatment member into the first air passage, and the first air passage communicates with the ventilation member.

In this solution, the second treatment element replaces the first treatment element. When the balloon is squeezed, oxygen acts on the duckbill valve to open the one-way valve flap, and the opening of the one-way valve flap is an outward movement. During the process, the second treatment piece will be touched, and the second treatment piece will be broken under the action of the impulse, forming a In the leakage channel, the therapeutic drug leaks from the leakage channel into the air passage one, then enters the ventilator, and finally enters the human respiratory tract to play a role. In this solution, the second treatment piece is squeezed by the impulsive force when the one-way valve flap is opened, so that the medicine inside the treatment piece can flow out, the existing structure is fully utilized, the structure design is ingenious, and the structure is simple. The ventilator may be a mask or a tracheal intubation tube, etc., both of which are directly connected to the breathing valve, which are not described in detail, and belong to the prior art.

In the above-mentioned respiratory skin bag, the second treatment member includes a bag body in the shape of a circular ring with a cavity inside, the bag body has a convex body that protrudes outward and has a cavity inside, and the convex body is connected to the body. The capsule bodies are blocked by a diaphragm, and the convex body is provided with a flow hole.

The therapeutic drug is filled in the capsule, and the therapeutic drug is preferably powder, and the therapeutic drug does not fill the inner cavity of the capsule, leaving a small part of the space for the impulse to play a role. When the one-way valve flap squeezes the capsule body, the squeezing force breaks the diaphragm, the therapeutic drug enters the convex body, and finally flows out from the orifice. The setting of the convex body plays a transitional role, which can prevent the therapeutic drug from leaking directly from the diaphragm rupture, which will lead to fast flow rate, waste of the drug, and the risk of overdose. When the diaphragm is broken, the drug enters the convex body, and the flow hole with a smaller pore diameter realizes the outflow of the therapeutic drug, restricts the flow rate, and reduces the waste of the drug, and the structure design is ingenious.

In the above breathing bag, the wall thickness of the diaphragm is smaller than the wall thickness of the bag body.

This size design enables the one-way valve flap to break through the diaphragm smoothly when it squeezes the bladder.

In the above breathing bag, the second treatment member is made of nylon, and the thickness of the diaphragm does not exceed 0.5mm.

This size design can make the impact force of the one-way valve flap smoothly open the diaphragm.

In the above-mentioned breathing skin bag, an annular inlay groove is formed on the inner wall of the inner end of the exhalation valve, and a part of the bag body is embedded in the inlay groove.

The second treatment piece is for one-time use, and the capsule body can be snapped into the embedded groove during installation.

Compared with the prior art, the breathing skin bag has the following advantages:

1. The breathing bladder uses extrusion power to send the therapeutic drug into the patient's respiratory tract, and simulates the patient's inhalation operation through reverse injection, realizing a non-intravenous treatment method, which greatly improves the safety of treatment and reduces the load on the human body. Reduce adverse reactions.

2. The breathing capsule has sufficient oxygen power through external force injection, and the medicine moves rapidly. Compared with active inhalation, the medicine can reach the respiratory tract quickly, and the effect is quick.

3. The breathing bag makes full use of the basic functions of the ordinary breathing bag to supply oxygen to the patient and help him to quickly restore normal breathing. The concept is novel and ingenious.

4. The breathing skin capsule is designed with a built-in capsule. When the therapeutic drug in the capsule is used up, the shell can be opened to replace the capsule. After the capsule is pierced, a leak is formed, and the air flow takes away the therapeutic drug through the leak. It can be used anywhere, and the design is ingenious and convenient.

5. The therapeutic drug in the breathing skin bag is powder, which does not flow freely like liquid. The powder is light in weight and can quickly flow into the respiratory tract with the airflow, so that the effect is rapid and effective.

6. The breathing bladder squeezes the treatment piece 2 with the help of the momentum when the one-way valve flap is opened, so that the medicine inside the treatment piece can flow out, making full use of the existing structure, the structure design is ingenious, and the structure is simple.

As shown in Figures 1 to 8, the breathing bag includes a balloon 1, an installation tube 2, a safety valve 3, a duckbill valve 4, an exhalation valve 5 and a ventilator, one end of the installation tube 2 is connected to one end of the balloon 1, The safety valve 3, the duckbill valve 4 and the exhalation valve 5 are connected to the installation pipe 2. The exhalation valve 5 has an air passage-5a, and also includes a treatment piece 6. The treatment piece 6 includes a housing 6a. 6a has an air passage two 6b, one end of the air passage two 6b is an inlet 6b1, and the other end is an outlet 6b2, the inlet 6b1 of the air passage two 6b is communicated with the air passage one 5a, and the outlet of the air passage two 6b is connected. 6b2 is communicated with the ventilator, and the housing 6a also has a therapeutic drug. When the duckbill valve 4 is opened, the therapeutic drug can be discharged from the outlet 6b2 along the airflow into the ventilator.

The breathing bag is a common tool in the field of medical breathing. In general, its purpose is to provide artificial ventilation and oxygen supply to patients without artificial airways, without spontaneous breathing, or with weak and irregular breathing and severe poor ventilation. , duckbill valve 4, balloon 1, oxygen gas storage valve, oxygen gas storage bag and oxygen conduit, there is a socket on the mask, and the mask is connected to the exhalation valve 5 through the socket to achieve communication, and the oxygen gas storage bag is connected to the balloon 1. The oxygen catheter is connected to the balloon 1 and the oxygen source. Before the operation, it is necessary to inspect all parts of the breathing bag, then open the airway, remove foreign bodies in the oral cavity, then cover the patient's mouth and nose with the mask, and place the middle finger, ring finger and little finger of one hand on the patient's jaw to keep the patient's mouth open, index finger, Put the thumb on the mask (CE method), press it tightly without air leakage, and squeeze the balloon 1 with the right hand. After the balloon 1 is squeezed, the oxygen enters the duckbill valve 4 through the installation tube 2. Expanding to the valve flap 4a, oxygen continues to enter the air passage 5a of the exhalation valve 5, then enters the mask, and finally enters the patient's body to achieve oxygen supply. The air valves 5 are adjacent to each other with a gap therebetween. When the patient's mouth is closed or a blockage occurs in the air passage 1 5a, the oxygen can directly reverse the movement to open the air valve 5b to realize rapid deflation. The installation pipe 2 is used to install various types of valves. The above is the basic operation process of the breathing bag, which will not be described in detail. The installation methods and detailed structures of components such as the duckbill valve 4, the exhalation valve 5, and the safety valve 3 will not be described in detail. They are all in the prior art.

In this solution, a therapeutic element 1 6 is added to the breathing skin bag. After pressing the balloon 1, oxygen passes through the air passage 1 5a and the air passage 2 6b. Under the action of oxygen, the therapeutic drug in the housing 6a follows the airflow. Enter into the ventilator, thereby acting on the respiratory tract, so that the asthma symptoms can be quickly relieved, and the ventilator plays the role of ventilation conduction here. This program uses extrusion power to deliver the therapeutic drug into the patient's respiratory tract, and simulates the patient's oral inhalation operation through reverse injection, realizing a non-intravenous treatment method, which greatly improves the safety of treatment, reduces the load on the human body, and reduces adverse reactions. . At the same time, this external force injection method has sufficient oxygen power and rapid drug movement. Compared with active inhalation, it can make the drug reach the respiratory tract quickly, and the effect is quick. In addition, it also makes full use of the basic function of the breathing bladder to supply oxygen to the patient to help him quickly resume normal breathing. The concept is novel and ingenious.

Specifically, the vent is a face mask. When the ventilation member is a mask, the mask and the housing 6a are plugged or tightly fitted, and can be disassembled at any time. In this scheme, the respiratory capsule plays two roles of oxygen supply and treatment. The oxygen supply function is not repeated here, but is the basic function. During the treatment, open the patient's mouth, put the mask on the patient's face until it is airtight, and then squeeze the balloon 1.

The above structure realizes that the snap ball 6a1b2 enters into the snap groove 6a2b by extrusion deformation, and the snap ball 6a1b2 is reset after being squeezed to realize the connection between the left casing 6a1 and the right casing 6a2. When separating the left casing 6a1 and the right casing 6a2, break them apart so that the buckle ball 6a1b2 is deformed and separated from the buckle groove 6a2b.

For the puncturing structure, the normal oxygen supply function of the breathing bladder can also be used directly without puncturing the capsule 7. Of course, in order to pursue a higher flow rate, the treatment part 1 can be disassembled as a whole, and then the ventilation part can be connected It can be placed on the exhalation valve 5, which can perfectly realize the function switching. The structure design is ingenious, convenient and fast.

Embodiment 2

As shown in FIG. 9 , this embodiment differs from Embodiment 1 in that the piercing structure is different. Specifically, the piercing structure includes a through-hole 6c opened on the casing 6a, and the through-hole 6c penetrates to the capsule. 7. The outer end of the through hole 6c is blocked by the stud 9 . In this solution, an external tool needs to be used to puncture the capsule 7 by unscrewing the stud 9 and using a sharp object to pierce the capsule 7, and then reset the stud 9. This solution reduces the complexity of the treatment part 1 6, Simplify the structure.

Embodiment 3

As shown in Figures 10 to 12, the breathing bag includes a balloon 1, an installation tube 2, a safety valve 3, a duckbill valve 4, an exhalation valve 5 and a ventilator. One end of the installation tube 2 is connected to one end of the balloon 1. The safety valve 3, the duckbill valve 4 and the exhalation valve 5 are connected to the installation pipe 2. The exhalation valve 5 has an air passage 1 5a, and also includes a treatment part 2 12. When the one-way valve flap 4a of the mouth valve 4 is opened, the second treatment member 12 is broken open and the treatment drug leaks from the second treatment member 12 into the air passage one 5a, and the air passage one 5a communicates with the ventilation member. In this solution, the second treatment element 12 replaces the treatment element one. When the balloon 1 is squeezed, oxygen acts on the duckbill valve 4 to open the one-way valve flap 4a, and the opening of the one-way valve flap 4a is an outward movement. The second 12 is broken open to form a leakage channel, and the therapeutic drug leaks from the leakage channel into the air passage 1 5a, then enters the ventilator, and finally enters the human respiratory tract to play a role. This solution squeezes the treatment part 2 12 by the momentum when the one-way valve flap 4a is opened, so that the medicine inside the treatment part can flow out, and the existing structure is fully utilized, and the structure design is ingenious and the structure is simple. The ventilator may be a mask or a tracheal intubation tube, etc., both of which are directly connected to the breathing valve, which are not described in detail, and belong to the prior art.

Specifically, the second treatment member 12 includes a spherical body 12a with a cavity inside. The bladder body 12a has a convex body 12b that protrudes outward and has a cavity inside. The convex body 12b is connected to the bladder body The space between 12a is blocked by a diaphragm 12c, and a flow hole 12b1 is formed on the convex body 12b. The therapeutic drug is filled in the capsule body 12a, and the therapeutic drug is preferably powder, and the therapeutic drug does not fill the inner cavity of the capsule body 12a, leaving a small part of the space for the impulse to play a role. When the one-way valve flap 4a squeezes the capsule 12a, the squeezing force breaks the diaphragm 12c, and the therapeutic drug enters the convex body 12b, and finally flows out from the orifice 12b1. The arrangement of the convex body 12b plays a transitional role, which can prevent the therapeutic drug from leaking directly from the rupture of the diaphragm 12c, which will lead to fast flow rate, waste of the drug, and risk of overdose. When the diaphragm 12c is broken open, the medicine enters the convex body 12b, and the flow hole 12b1 with the smaller aperture realizes the outflow of the therapeutic medicine, which limits the flow rate and reduces the waste of medicine. The structure design is ingenious. The wall thickness of the septum 12c is smaller than the wall thickness of the capsule 12a. This dimension design enables the one-way valve flap 4a to break through the diaphragm 12c smoothly when pressing the capsule 12a. The second treatment piece 12 is made of nylon, and the thickness of the diaphragm 12c is not more than 0.5mm. This dimension design enables the impact force of the one-way valve flap 4a to pierce the diaphragm 12c smoothly. The inner wall of the inner end of the exhalation valve 5 is provided with a ring-shaped embedded groove 5c, and a part of the bladder 12a is embedded in the embedded groove 5c. The second treatment piece 12 is for one-time use, and the capsule body 12a can be snapped into the embedded groove 5c during installation.
