Description

Technical Field

[0001] The present invention relates to the technical field of nebulizer medical devices, and in particular to a pediatric nebulizer. Background Art

[0002] A nebulizer is a device that can atomize liquid medicine into gaseous medicine for patients to inhale, achieving the same therapeutic effect as liquid medicine. Children are usually treated with nebulizers, so this device is widely used in pediatric departments of hospitals. However, since the size of children's faces varies with age, the nebulizers on the market currently have a uniform caliber, which leads to many problems in actual use.

[0003] First, children of different ages require nebulizers of different calibers. Some children need a large caliber, while others need a small caliber. The existing uniform caliber design will affect the absorption of drugs by children. Secondly, the fixed caliber design leads to waste of nebulizer gas, especially when the caliber is too large, the gas cannot be effectively inhaled. Devices with too small a caliber cannot fit tightly to children's faces, seriously affecting the use effect, while also increasing the waste of drugs and treatment costs, making ordinary nebulizers less practical. Summary of the invention

[0004] The invention provides a pediatric nebulizer, which mainly improves the structure of the mouthpiece to solve the problem that the mouthpiece size cannot be personalized to adapt to children of different ages and face shapes, thereby causing waste of liquid medicine or insufficient comfort.

[0005] The purpose of the present invention is achieved through the following technical solutions: A pediatric nebulizer consists of a mouth mask and a main body. A guide plate is detachably fixed on the inner side of the mouth mask, and an additional part is detachably fixed on the outer side of the mouth mask.

[0006] Furthermore, at least one air-permeable member is provided at the upper third of the mouth mask, and the main body is connected at the 1 / 2 or lower 1 / 3 position of the mouth mask.

[0007] Furthermore, a filtering air hole is provided at one third of the upper side of the mouth mask, fixing holes are symmetrically provided on both sides of the filtering air hole, and the air permeable member is composed of the filtering air hole and the air hole.

[0008] Furthermore, the edge of the outer side surface of the mouth mask is recessed inward to form a fixing groove, and the fixing groove is used to fix the additional component.

[0009] Furthermore, the additional component is composed of an annular widened portion, and a bending portion and a snap-in portion which are sequentially connected to the outside of the widened portion, and the snap-in portion is snapped into the fixing groove for fixation.

[0010] Furthermore, two groups of guide plate fixing brackets are fixed on the inner side of the mouth mask in a bilaterally symmetrical manner, and the two groups of guide plate fixing brackets are arranged in an "eight" shape. The guide plate fixing brackets are used to temporarily fix the guide plates.

[0011] Furthermore, the center of the uppermost group of guide plate fixing brackets is located at 1 / 3 of the top of the mouth mask, and the position of the lowermost group of guide plate fixing brackets does not exceed 1 / 2 of the height of the mouth mask.

[0012] Furthermore, the guide plate is formed by connecting a first plate and a second plate, and the connection angle between the second plate and the first plate is 30-45°.

[0013] Furthermore, the shortest dimension of the second plate is half of the dimension of the first plate.

[0014] Furthermore, the second plate has two through holes, and the through holes are used for gas and atomized liquid to flow.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The invention enables the universal mouth mask to be suitable for faces of different ages, face shapes and sizes by placing the deflector plates at different positions and using additional parts. The present invention insists on adopting a simple structural design and a detachable assembly method, which is suitable for quick disassembly and disinfection, and it is not easy to leave dead corners during disinfection. For example, the fixing groove is set on the outside to reduce the residual liquid, reduce the difficulty of cleaning, and extend the use time and safety of the mouth mask; The bent portion cooperates with the nose pad and the chin pad, which not only improves the sealing of the mouth mask, avoids the large-scale leakage of the atomized liquid from the periphery of the mouth mask, but also improves the comfort during use.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings and embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Based on the improvement of the existing portable or hospital-used nebulizers, the mouth mask connected to the nebulizer host is mainly optimized. By improving the structure of the mouth mask, it can be suitable for children of all ages, face shapes or weights. The purpose is to make the improved mouth mask fit tightly on the child's face, covering the mouth and nose, so that the atomized medicine is not easy to escape outside the mouth mask; secondly, the fit between the mouth mask and the face needs to be comfortable enough.

[0020] In addition to the above two purposes, the possibility of industrialization needs to be considered. The mouth mask can be used once or repeatedly for disinfection. For disposable mouth masks, complex structures and the use of multiple materials should be avoided as much as possible, as this will increase manufacturing costs and lead to great waste. If it is used for repeated disinfection, attention should be paid to the thoroughness and convenience of disinfection, as the drug solution can easily leak onto the inner surface of the mouth mask, and ease of disassembly and cleaning becomes an important indicator for improvement and optimization.

[0021] In summary, the improvement of the present invention needs to achieve the following: avoid using multiple materials for splicing, avoid using complicated small parts, and ensure that disassembly and assembly are quick, and there will be no residue when cleaning. Example

[0022] This embodiment provides a pediatric nebulizer, such as Figure 1As shown, the pediatric nebulizer consists of a mouth mask 10 and a main body 20, wherein the mouth mask 10 and the main body 20 are connected by a connecting tube, and the main body 20 can be a portable home machine (a portable home device is shown in this embodiment) or a large-scale hospital nebulizer. The main body equipment adopts the existing equipment on the market, and the main body 20 is connected to the mouth mask through the main body connection port 210, so the size of the main body connection port 210 matches the host equipment on the market. Of course, in order to enhance the universality and sealing of the adaptation, a sealing ring is fixed inside the main body connection port 210.

[0023] like Figure 2 As shown, the shape of the mouth mask 10 is the same as that in the prior art, but in this embodiment, the connection position of the mouth mask 10 and the main body 20 is changed. In the prior art, the mouth mask 10 and the main body 20 are usually connected in the middle position or directly below the mouth mask. This connection method often causes the problem of atomized liquid accumulation during the atomization process. This embodiment adjusts the connection position. First, the center of the filter air hole 110, which mainly plays a ventilation role, is placed at the upper third of the mouth mask. In addition, air holes 120 are opened at the peripheral position of the filter air hole 110. In this embodiment, the number of air holes 120 is two, which are respectively located on both sides of the filter air hole 110. The structures of the filter air hole 110 and the air hole 120 are both based on the prior art, but in this embodiment, the filter air hole 110 can replace the air permeable net with a semi-permeable membrane. The advantage of the semi-permeable membrane is that it can facilitate the transmission of exhaled gas and has a certain sealing performance.

[0024] In this embodiment, the filter air holes 110 and the air holes 120 are arranged at the upper third, which just matches the position of the nasal cavity, and is conducive to the rapid discharge of gas.

[0025] like Figure 3 As shown, in this embodiment, there is a circle of fixing groove 130 at the edge of the outer side (close to the skin), and the fixing groove 130 is used to fix the additional component 40. The structure of the fixing groove 130 is formed by the outer surface being recessed inward.

[0026] Figure 4 2 is a schematic diagram of the structure of the inner side 200 of the mouth mask 10 of this embodiment. In addition to adjusting the positions of the filter air holes 110 and the air holes 120, the center of the main body connection port 210 for connecting the main body 20 is adjusted to the 1 / 2 or lower 1 / 3 position of the mouth mask. Compared with the prior art, the position of the main body connection port 210 corresponds exactly to the position under the user's mouth and nose, which is conducive to the rapid inhalation of the liquid after atomization processing by the user.

[0027] At the same time, a guide plate 30 is added to the inner side of the mouth mask 10 to further guide the atomized liquid and the gas exhaled by the user, thereby improving the atomization efficiency and the comfort of the patient, and reducing the accumulation of the atomized liquid in the mouth mask 10. In order to cooperate with the use of the guide plate 30 and facilitate disassembly and cleaning, two groups of guide plate fixing brackets 220 are fixed on the inner side 200 in a left-right symmetrical manner, and the guide plate 30 is inserted into an adjacent group of guide tube fixing brackets 220 for temporary fixation.

[0028] Specifically, the guide plate fixing brackets 220 are arranged in an "eight" shape, and the middle position of the guide plate fixing brackets 220 in the uppermost row is located on the upper side of the mouth mask 10 and at a position 1 / 3 away from the top position of the mouth mask 10. At least three groups of guide plate fixing brackets 220 are arranged at intervals from this position, and the lowermost position of the guide plate fixing brackets 220 in the lowermost group does not exceed 1 / 2 of the entire height of the mouth mask 10. Placing the guide plate 30 at this position can well separate the gas breathed by the user and the atomized liquid entering the mouth mask 10.

[0029] The structure of the guide plate 30 is as follows: Figure 5 As shown, the first plate 310 and the second plate 320 are integrally connected. The smallest size of the second plate 320 is half the size of the first plate 310, and the second plate 320 is connected to the first plate 310 at an angle of 30-45 degrees. The second plate 320 has two large through holes 330 for gas circulation.

[0030] In order to meet different size requirements, an additional part 40 is added in this embodiment, such as Figure 6 As shown, the attachment 40 is made of a sheet of silicone material. The attachment 40 is composed of a widening portion 400, and a bending portion 410 and a snap-in portion 420 connected to the outside of the widening portion 400 in sequence. After the attachment 40 is placed, the widening portion 400 will reduce the open area of ​​the mouth mask 10, thereby adapting to different usage requirements. The attachment 40 is snapped in place by the bending portion 410 and the snap-in portion 420. The thickness of the bending portion 410 is thinner than that of the widening portion 400 and the snap-in portion 420. Figure 7 As shown, when it is used, it is directly bent, and then the snap-in portion 420 is snapped into the fixing groove 130 to fix it. The advantage of adopting the outsourcing solution is that it is easy to disassemble the additional part 40, the fixing groove 130 is located on the outside, which is easy to clean, and the bent portion 410 can also play a sealing role, preventing the atomized liquid from leaking from the part of the mouth mask 10 that contacts the skin.

[0031] In order to enhance the sealing effect and further improve the comfort, a nose pad 430 and a chin pad 440 are respectively installed on the upper and lower sides of the additional part 40, which not only play a role of auxiliary fixation, but also play a role of comfortable sealing.

[0032] How to use: Figure 8 As shown, the use of this embodiment is shown, and the flow of atomized liquid and breathing gas is illustrated. The guide plate 30 is inserted into the appropriate position of the guide plate fixing bracket 220 and fixed. The specific position can be adjusted according to different users, and the second plate 320 is located at the position of the user's nose after placement. At this time, when in use, most of the gas exhaled by the user will flow out quickly along the direction of the second plate 320 and the first plate 310 through the filter air holes 110 and the air holes 120. At the same time, the atomized liquid enters the mouth mask 10 through the main body connection port 210, and its position just corresponds to the position under the user's mouth and nose. Most of the atomized liquid is quickly absorbed through the mouth and nose, and a small part of the atomized liquid blocked by the first plate 310 can also flow along the through holes on the first plate 310 and the second plate 320 to the user's nose.

[0033] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
