According to the drug delivery requirements of different nasal cavity drug delivery positions, the drug dosing device 11 can be equipped with different soft spray heads. The following is a detailed description of the soft spray nozzles provided by different nasal cavity administration positions.

First of all, a detailed description of the entire group of sinus applicators used for the position of the sinuses in the nasal cavity:

It should be noted that there are 4 groups of 8 sinuses in the nasal cavity, including: frontal sinus, maxillary sinus, ethmoid sinus, sphenoid sinus and so on. The position, angle, and depth of each sinus are different. The method of flooding and blind irrigation through the nasal cavity, after the sinus surgery for individual sinuses is opened, it is possible that the liquid can enter the maxillary sinus through the open position In the sinus body, there is no ability to accurately align each opened sinus body to flush the sinus body, and precise drug delivery cannot be achieved. Therefore, there is a need for a device that can achieve and accurately target and flush each open sinus body in the entire group of sinuses.

In practical applications, there are many types of nasal sinus drug delivery positions. Fig. 1 is a schematic diagram of the nasal sinus drug delivery positions provided in an embodiment of the application. As can be seen from Figure 1, there are frontal sinus 1 located in the upper and front of the nasal cavity, ethmoid sinus 2 located in the upper middle of the nasal cavity, sphenoid sinus 3 located in the upper and rear of the nasal cavity, and maxillary sinus 4 located below the nasal cavity. For different diseases, the place where the drug needs to be administered is also different. Some drug delivery positions have special angles, and it is difficult for conventional drug delivery devices to accurately perform drug delivery. Therefore, in order to achieve precise drug delivery, corresponding spray holes can be provided on the soft spray head for different drug delivery positions.

Fig. 2 is a schematic structural diagram of a whole group of nasal sinus applicators provided by an embodiment of the application. As shown in FIG. 2, the drug delivery device includes: a drug adding device 11 and a soft spray head 22. The dosing device 11 and the soft spray head 22 are movably connected through the base, for example, it can be connected by a snap connection, an embedded connection, etc., or a combination of multiple connection methods can be used to ensure the connection part after the movability connection The sealing effect prevents air leakage or liquid leakage during the spraying process. The connection structure is simple, which is convenient for users to disassemble and assemble.

In order to meet the user's drug delivery requirements for different nasal sinus drug delivery positions, the dosing device 11 can be equipped with different soft spray heads. For example, it can include a first soft spray head 7 for spraying drugs to the ethmoid sinus 2 on the front of the nasal cavity. , The second soft spray nozzle 8 used to spray medicine for the frontal sinus 1 in the upper middle position of the nasal cavity, the third soft spray nozzle 9 used to spray medicine for the sphenoid sinus 3 above and behind the nasal cavity, used to spray the maxillary sinus below the nasal cavity 4 The fourth soft spray nozzle 10 for spraying medicine. It can be seen from the figure that different soft nozzles have different shapes (for example, cylindrical, conical, irregularly curved, etc.) and different sizes (for example, different lengths, different thicknesses, etc.).

In order to meet the spraying requirements, spray holes are also provided on each soft spray head, and the positions of the spray holes on different soft spray heads are different. Specific examples of the positions of spray holes in various types of soft spray nozzles will be given below.

The medicine dosing device also includes a medicine storage bin 11a, and the medicine storage bin 11a may be located on the upper part of the pressing part 11b, or may be located in the vent pipe 11c. As shown in Fig. 2, when in use, by applying pressure to the pressing member, an air flow is generated to spray the medicine through the soft spray nozzle to the sinus administration site through the ventilation duct 11c.

In order to facilitate understanding, the different soft nozzles will be described in detail below.

FIG. 3 is a schematic diagram of the structure of the first soft spray head provided by an embodiment of the application. The soft nozzle includes a first soft nozzle 7, which can also be referred to as a D-type nozzle in practical applications. The first soft spray head 7 is used to spray the medicine in the medicine storage bin of the medicine adding device to the nasal cavity and ethmoid sinus 2. In other words, when the user needs to spray medicine on the nasal cavity and ethmoid sinus 2, he can choose the first soft spray head 7.

One end of the first soft spray head 7 is provided with a first base 71 for connecting with the dosing device 11, and the other end of the first soft spray head 7 is provided with a first spray hole 72. A spray hole 72 is arranged on the axis of the first soft spray head. During use, when it is determined that it is necessary to apply medicine to the nasal cavity and ethmoid sinus 2, the first soft spray head 7 can be selected and the first soft spray head 7 and the medicine dosing device 11 can be movably connected through the first base 71. Fig. 4 is a schematic diagram of drug delivery through the first soft spray nozzle provided by an embodiment of the application. After adding the medicine 19 to the medicine storage compartment 11a, insert the first soft spray head 7 into the nose contour 21, and simply adjust the insertion depth of the first soft spray head 7. It may be necessary to adjust the orientation slightly to make the first soft spray head 7 The spray hole 72 is aligned with the nasal cavity and ethmoid sinus 2, and the first spray hole 72 does not exceed the uncinate process 5. In use, the medicine 19 enters the cavity 13 of the first soft spray head 7 through the liquid outlet 20, and then is sprayed out through the first spray hole 72, and sprayed into the nasal cavity and the ethmoid sinus 2.

It can be seen from FIG. 3 and FIG. 4 that the first soft nozzle 7 has a cone shape, and the cone shape contains a cavity 13 inside. The first spray hole 72 is located at the top of the cone of the first soft spray head 7. When pressure is applied to the dosing device 11, the medicine will be sprayed directly to the front position through the first spray hole 72.

It can be seen from Figure 1 that the nasal cavity and ethmoid sinus 2 is located on the upper front of the nasal cavity. When the first soft spray head 7 is inserted into the nasal cavity, the first spray hole 72 is exactly aligned with the nasal cavity and ethmoid sinus 2, which can accurately spray the medicine to the nasal cavity. The nasal cavity and ethmoid sinus 2 only need to rotate the soft spray head along the axis in the limited space of the nasal cavity, which can meet the targeted drug delivery needs, and it is easier and more convenient for the user to use it without the user's more complicated orientation adjustment.

Fig. 5 is a schematic structural diagram of a second soft spray head provided by an embodiment of the application. The soft spray head 22 also includes a second soft spray head 8, which can be referred to as an A-type spray head in practical applications; The medicine is sprayed into the nasal cavity and the ethmoid sinus 2 and the frontal sinus 1. In other words, when the user needs to spray medicine on the nasal cavity and the ethmoid sinus 2 and the frontal sinus 1, the second soft spray head 8 can be selected.

One end of the second soft spray head 8 is provided with a second base 81 for connecting with the dosing device 11, and the other end of the second soft spray head 8 is provided with a second spray hole 82; The mass spray head 8 is tapered, the second spray hole 82 is located on the side wall of the cone top, and the included angle between the second spray hole 82 and the axis of the second soft spray head 8 is greater than 0 degrees and less than 90 degrees. During use, when it is determined that the nasal cavity and frontal sinuses 1 needs to be sprayed with medicine, the second soft spray head 8 can be selected and the second soft spray head 8 is movably connected with the medicine dosing device 11 through the second base 81. Fig. 6 is a schematic diagram of drug delivery through a second soft spray nozzle provided by an embodiment of the application. After adding the medicine 19 to the medicine storage compartment 11a, insert the second soft spray head 8 into the nose contour 21, and simply adjust the insertion depth of the second soft spray head 8. It may be necessary to adjust the orientation slightly to make the second spray The medicine hole 82 is aligned with the nasal cavity frontal sinus 1, and the second medicine spray hole 82 does not exceed the uncinate process 5. It should be noted that the depth adjustment mentioned here is due to the difference in the space of the user's nasal cavity. Therefore, it is necessary to adjust the insertion depth of the second soft nozzle 8 according to the depth of the nasal cavity. The orientation adjustment mentioned here is because the second spray hole 82 is provided on the side wall of the tapered top, and the direction of the second spray hole 82 needs to be rotated, for example, by rotating the second base 81 to rotate it along the axis , No need for the user to adjust the position or angle of the dosing device. In use, the medicine 19 enters the cavity 13 of the second soft spray head 8 through the liquid outlet 20, and then is sprayed through the second spray hole 82, and sprayed into the nasal cavity and frontal sinus 1.

It can be seen from FIG. 5 and FIG. 6 that the second soft nozzle 8 has a cone shape, and the cone shape contains a cavity 13 inside.

It should be noted that the depth adjustment mentioned here is because the depth space of the user's nasal cavity and nasopharynx is different. Therefore, it is necessary to adjust the insertion depth of the soft nasopharyngeal nozzle 6 in the nasal cavity contour 100 according to the depth of the nasal cavity. The second angle refers to the adjustment of the overall angle of the applicator. The orientation adjustment mentioned here is because the spray hole 62 is arranged on the side wall of the arc-shaped curved top, and the orientation of the spray hole 62 needs to be rotated axially.

The required drug delivery position 40 of the pharynx can meet the targeted drug delivery requirements without the user's complicated angle adjustment, which makes the user's use more simple and convenient.

It should be noted that in order to facilitate the user to adjust the direction of the nasopharyngeal soft nozzle along the axis 63 through the base, an indicating protrusion 16 may be provided on the base of the nasopharyngeal soft nozzle. The indicating protrusion 16 and the nozzle The medicine holes 62 are all located on the same side of the soft nozzle 6 in the nasopharynx.
