A children's nebulizer for assisting inhalation

Abstract

This invention relates to the field of medical nebulizers, specifically to a nebulizer for children that assists inhalation. It includes a cup base, an inner cup body, and a mouthpiece. The mouthpiece comprises a rigid section and a flexible section connected together. The rigid section is detachably connected to the mist outlet tube of the cup base. A rigid branch tube is provided at the front of the rigid section, located inside the flexible section and connected at its front. The mist outlet tube is a telescopic tube, externally fitted with a corrugated tube. This invention, through the combination of the flexible section and the rigid branch tube, allows the user's mouth to make a certain degree of contact with the mouthpiece without changing the mist output, improving discomfort for children. Simultaneously, when the patient exhales, the exhaled warm air enters the corrugated tube, causing the corrugated tube and the mist outlet tube to extend, providing extended storage space for the nebulized medication. This prevents the nebulized medication from accumulating and forming large droplets, maintaining the uniformity of the nebulized medication particles and improving the nebulization inhalation effect.

Description

Technical Field

[0001] The invention relates to the field of medical nebulizers, and in particular to a nebulizer for children that assists inhalation. Background Art

[0002] Medical nebulizer is an inhalation device. Compared with the traditional method of taking medicine to treat respiratory diseases such as asthma, medical nebulizer atomizes the liquid medicine into tiny particles. The medicine enters the respiratory tract and lungs through inhalation, thus achieving painless, rapid and effective treatment. The method of use is to inject the liquid medicine into the nebulizer, add an appropriate amount of diluent, then turn on the power device, connect the nebulizer to the compressed air pump, pressure cycle ventilator or oxygen cylinder, and when the mist begins to appear, put the mouthpiece into the mouth or cover the face with a mask, inhale the airflow in a quiet state, so that the atomized liquid medicine reaches the patient's body.

[0003] Most of the existing nebulizers for children are mask-type or mouthpiece-type. When using a mask-type nebulizer, the child's mouth is often unconsciously closed, which makes it difficult for the nebulized liquid to enter the oral cavity, reducing the treatment effect. The patent document with publication number CN117482341A discloses a nebulizer for children with an auxiliary mouth-opening structure. The nebulizer for children uses an expansion component designed by the designer to pry open the child's mouth. Although the medicine can be inhaled into the oral cavity, it significantly increases the discomfort of children. The mouthpiece-type nebulizer cannot adapt to the mouth shape of all children because the entrance is relatively hard. In addition, because the child needs to open his mouth for a long time when using it, it also increases the discomfort of the child.

[0004] The information disclosed in the background technology section of the present invention is only intended to deepen the understanding of the general background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art. Summary of the invention

[0006] The present invention provides a pediatric nebulizer for auxiliary inhalation, which adopts the following technical scheme:

[0007] The cup holder has an air inlet pipe at the bottom, the top of the air inlet pipe is narrowed to form an air jet port, a liquid medicine cavity is provided inside the cup holder, and a mist outlet pipe is provided on one side of the top of the cup holder;

[0008] The inner cup body is inserted into the cup holder and sleeved on the air inlet pipe. A liquid outlet channel is formed between the inner cup body and the air inlet pipe. The bottom of the liquid outlet channel is connected to the liquid medicine cavity and the top is connected to the inner space of the cup holder. A baffle is provided above the liquid outlet channel.

[0009] The cup spout includes a hard section and a soft section. The hard section is tubular and open at one end. The open end of the hard section is detachably connected to the mist outlet pipe. The soft section can be elastically deformed. The soft section is arranged at the front end of the hard section. The soft section is tubular and has a rubber partition at the front end. A plurality of hard branch pipes are arranged at the front end of the hard section. One end of the hard branch pipe away from the hard section is connected to the rubber partition. The hard branch pipe is connected to the outside and the mist outlet pipe. The connection method of the hard branch pipe and the hard section is configured so that the hard branch pipe can be displaced with the deformation of the soft section when the soft section is bitten and the mist outlet amount can be kept unchanged.

[0010] Optionally, the mist outlet pipe is a telescopic pipe, which includes a fixed pipe and a sliding pipe, the fixed pipe is fixedly connected to the cup holder, the sliding pipe is slidably inserted into the fixed pipe and is detachably connected to the hard section of the cup mouth, an elastic member and a bellows are connected between the fixed pipe and the sliding pipe, the elastic member is located inside the bellows, and the elastic member makes the mist outlet pipe initially in a shortened state;

[0011] A number of hoses are arranged on the side wall of the cup mouth, one end of the hoses is connected to the internal space of the soft section, and the other end is connected to the bellows, a number of exhalation holes are arranged on the rubber partition, and a one-way diaphragm is arranged at the end of the hard branch pipe, which is in an open state during inhalation and in a closed state during exhalation.

[0012] Optionally, the one-way diaphragm is initially in a closed state and has a micro mist outlet in the closed state.

[0013] Optionally, a plurality of balancing air holes are provided on the side wall of the bellows, which can only let out air but not let in air. A one-way air valve is provided at either end of the hose, which is configured to only allow gas to enter the bellows from the inside of the soft section.

[0014] Optionally, the hard section is threadedly connected to the sliding pipe.

[0015] Optionally, the side wall of the cup mouth is provided with an air outlet hole for connecting the hose, and the air outlet hole is provided on the hard material.

[0016] Optionally, the hard section includes a connecting pipe and a hard partition plate arranged at the front end of the connecting pipe, the hard branch pipe is connected to the hard partition plate, and the rear end face of the hard partition plate is provided with a conical surface.

[0017] Optionally, the elastic member is a tension spring.

[0019] Optionally, a valve-type cup cover is provided on the top of the inner cup body, and the valve-type cup cover can adjust the size of the opening on the top of the inner cup body.

[0020] The beneficial effects of the present invention are as follows: a children's nebulizer for auxiliary inhalation of the present invention is provided with a cup mouthpiece including a soft section and a hard section, and a plurality of hard branch tubes located inside the soft section and with end portions connected to the soft section are provided at the front end of the hard section. During atomization, the soft section is placed in the mouth, because the setting of the soft section allows the user's mouth to bite the cup mouthpiece to a certain extent, and at the same time, the mist output is determined by the hard branch tubes. When the soft section is bitten, the hard branch tubes are appropriately moved with the biting action but the volume remains unchanged, so the mist output remains unchanged. Through the combination of the soft section and the hard branch tube, it is achieved that the user's mouth is allowed to bite the cup mouthpiece to a certain extent without changing the mist output, thereby improving the discomfort of children when using the device and being able to adapt to the mouth shapes of different children.

[0021] Furthermore, by setting the mist outlet pipe connected to the cup mouth on the cup holder as a retractable structure and setting a bellows on the outside of the mist outlet pipe, the exhaled gas enters the bellows during exhalation to stretch the bellows, thereby providing an extended storage space for the atomized medicine liquid, allowing the atomized medicine liquid to continue to move, and the atomized medicine liquid does not accumulate during exhalation, thereby preventing the atomized medicine liquid from accumulating into large particle droplets, maintaining the uniformity of the atomized medicine liquid particles, and improving the atomization inhalation effect.

[0022] Furthermore, when exhaling, the exhaled hot air enters the soft section and flows outside the hard branch tube, which can keep the atomized liquid in the hard branch tube warm to a certain extent and prevent the condensation of part of the atomized liquid due to excessive temperature difference in the outside world.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 6 As shown, a pediatric nebulizer for auxiliary inhalation provided by an embodiment of the present invention includes a cup holder 100 , an inner cup body 200 and a cup mouth 300 .

[0036] An air inlet pipe 110 is provided at the bottom of the cup holder 100, and the top of the air inlet pipe 110 is narrowed to form an air jet 130. A liquid medicine chamber 120 is provided inside the cup holder 100, and the liquid medicine chamber 120 is located between the inner peripheral wall of the cup holder 100 and the outer peripheral wall of the air inlet pipe 110. A mist outlet pipe 150 is provided on one side of the top of the cup holder 100.

[0037] The inner cup body 200 is inserted into the cup holder 100 and sleeved on the air inlet pipe 110. A liquid outlet channel 231 is formed between the inner cup body 200 and the air inlet pipe 110. The bottom of the liquid outlet channel 231 is connected to the medicine liquid chamber 120 and the top is connected to the internal space of the cup holder 100. There is a baffle 220 above the liquid outlet channel 231.

[0038] The cup mouth 300 includes a hard section 310 and a soft section 320. The hard section 310 is tubular and open at one end. The open end of the hard section 310 is detachably connected to the mist outlet pipe 150. The soft section 320 is made of elastic rubber material and can be elastically deformed. The soft section 320 is arranged at the front end of the hard section 310. The soft section 320 is tubular and has a rubber partition 324 at the front end. A plurality of hard branch pipes 330 are arranged at the front end of the hard section 310. One end of the hard branch pipe 330 away from the hard section 310 is connected to the rubber partition 324. The hard branch pipe 330 connects the outside and the mist outlet pipe 150. The connection method of the hard branch pipe 330 and the hard section 310 is configured so that the hard branch pipe 330 can be displaced with the deformation of the soft section 320 when the soft section 320 is bitten and the mist outlet amount is kept unchanged.

[0039] When in use, install the cup mouth 300 on the mist outlet pipe 150, take out the inner cup body 200 upwards, pour the liquid medicine to be atomized into the liquid medicine cavity 120, press the inner cup body 200 in and adjust the position, then connect the external air source at the air inlet pipe 110, start the external air source to pass compressed air into the air inlet pipe 110. The gas is ejected from the jet port 130. Because the jet port 130 is a constricted structure, the pressure of the gas near the jet port 130 is reduced to form a negative pressure, which attracts the liquid medicine in the liquid medicine cavity 120 to flow up from the liquid outlet channel 231. After the liquid medicine hits the baffle 220, it is dispersed and atomized and overflows from both sides, flowing to the mist outlet pipe 150, and the soft section 320 of the cup mouth 300 is placed in the mouth. As the person breathes, the atomized liquid medicine is gradually inhaled into the lungs. Because the setting of the soft section 320 allows the user's mouth to bite the cup mouth 300 to a certain extent, and the amount of mist output is determined by the hard branch tube 330, when the soft section 320 is bitten, the hard branch tube 330 moves appropriately with the biting action but the volume remains unchanged, so the amount of mist output remains unchanged. That is to say, the present invention allows the user's mouth to bite the cup mouth 300 to a certain extent without changing the amount of mist output through the combination of the soft section 320 and the hard branch tube 330, thereby improving the discomfort of children when using it and adapting to the mouth shapes of different children.

[0040] As a preferred embodiment of the present invention, refer to Figure 2 The air intake pipe 110 includes a cylindrical section at the bottom and a conical section connected to the upper end of the cylindrical section. The small end of the conical section faces upward to form a narrowed jet outlet 130. A cone bucket is provided in the cup holder 100. The cone bucket is located outside the air intake pipe 110 and forms a liquid medicine cavity 120 with the outer peripheral wall of the air intake pipe 110.

[0041] The inner cup body 200 includes an upper cylinder 210 and a support plate connected to the middle part of the lower end of the upper cylinder 210, and a cone 230 is arranged at the center of the support plate. The cone 230 is hollow inside, penetrated from top to bottom and the small end faces upward, and the cone 230 is sleeved on the outside of the air inlet pipe 110 and forms a liquid outlet channel 231 between the cone 230 and the air inlet pipe 110. A liquid outlet window is opened on the support plate at the top position of the cone 230, and the top surface and upper entity of the liquid outlet window form a baffle 220. After being attracted, the liquid medicine moves upward from the liquid outlet channel 231 to the liquid outlet window and hits the top surface (baffle 220) of the liquid outlet window, and then is decomposed and atomized, and overflows from both sides of the liquid outlet window under the diversion of the baffle 220, and finally moves to the mist outlet pipe 150.

[0042] In one embodiment, a circular cut is provided at the connection between the rear end of the hard branch tube 330 and the hard segment 310, so that the front end of the hard branch tube 330 can be appropriately displaced with the deformation of the soft segment 320 when the soft segment 320 is bitten, and after the biting force is removed, the soft segment 320 is reset, and the hard branch tube 330 is reset driven by the rubber diaphragm 324. In other embodiments, an elastic ring is provided at the connection between the rear end of the hard branch tube 330 and the hard segment 310, or a sealing ball is used for hinge connection, so that the front end of the hard branch tube 330 can be appropriately displaced with the deformation of the soft segment 320.

[0043] Specifically, the hard section 310 includes a connecting tube 312 and a hard partition 313 arranged at the front end of the connecting tube 312. The hard branch tube 330 is connected to the hard partition 313. The rear end face of the hard partition 313 is provided with a conical surface 331 to facilitate the atomized medicine liquid to enter the hard branch tube 330.

[0044] In a further embodiment, the mist outlet pipe 150 is a telescopic tube, which includes a fixed tube 152 and a sliding tube 151. The fixed tube 152 is fixedly connected to the cup holder 100, and the sliding tube 151 is slidably inserted into the fixed tube 152 and is detachably connected to the hard section 310 of the cup mouth 300. An elastic member 190 and a bellows 180 are connected between the fixed tube 152 and the sliding tube 151. The elastic member 190 is located inside the bellows 180. The elastic member 190 makes the mist outlet pipe 150 initially in a shortened state. The elastic member 190 is preferably a tension spring.

[0045] A plurality of hoses 340 are arranged on the side wall of the cup mouth 300, one end of the hose 340 is connected to the internal space of the soft section 320, and the other end is connected to the bellows 180. Specifically, an air outlet 314 is arranged on the outer wall of the cup mouth 300 for connecting the hose 340, a plurality of exhalation holes 321 are arranged on the rubber partition 324 at the end of the soft section 320, and a one-way diaphragm 332 is arranged at the end of the hard branch pipe 330, and the one-way diaphragm 332 is in an open state during inhalation and in a closed state during exhalation.

[0046] It is understandable that during the nebulization treatment process, the conventional nebulizer cooperates with the patient's inhalation, and the atomized medicine is inhaled into the human body to achieve the treatment purpose. However, because the human body exhales and inhales alternately, the atomized medicine is not inhaled during exhalation, but the atomized medicine still flows outward under the inertia of inhalation and the airflow of the intake pipe 110, which can easily cause accumulation, resulting in the medicine originally atomized into small particles to gather and collide into large droplets, affecting the nebulization effect. In the present invention, when a person inhales, the one-way diaphragm 332 opens, and the atomized medicine liquid is inhaled into the lungs through the hard branch tube 330; when the person exhales, the exhaled gas enters the internal space of the soft segment 320 through the exhalation hole 321, and enters the hose 340 through the outlet hole 314, and finally flows into the bellows 180. The pressure in the bellows 180 increases and expands, driving the sliding tube 151 away from the fixed tube 152, so that the mist outlet tube 150 stretches and the internal space becomes larger, providing an extended storage space for the atomized medicine liquid, avoiding the accumulation of the medicine liquid into large droplets, and when the person inhales again, the one-way diaphragm 332 opens, and the bellows 180 and the mist outlet tube 150 return to a contracted state under the pulling force of the elastic member 190. At the same time, the air outlet 314 is set at the position of the hard section 310, that is, close to the hard partition 313. The hot air exhaled by the human body enters the soft section 320 and flows around the periphery of the hard branch pipe 330 to form an insulation layer. It can play a certain degree of insulation role for the atomized liquid in the hard branch pipe 330 and prevent the excessive temperature difference from causing part of the atomized liquid to condense.

[0047] Furthermore, a plurality of one-way tiny balancing air holes are arranged on the side wall of the bellows 180, and the balancing air holes can only discharge air but not inlet air. A one-way air valve (not shown in the figure) is arranged at either end of the hose 340, and the one-way air valve is configured to only allow gas to enter the bellows 180 from the inside of the soft section 320. Specifically, the one-way air valve can be arranged at the cup mouth 300 or the sliding tube 151 of the mist outlet pipe 150. When the human body exhales, the gas enters the soft section 320 and enters the bellows 180 through the hose 340. At this time, the intake volume is much larger than the exhaust volume of the balancing air holes, and the bellows 180 stretches. When inhaling, the exhalation pressure decreases. Under the resetting action of the elastic member 190, the bellows 180 contracts, and the gas in the bellows 180 is squeezed out from the balancing air holes to prevent the gas in the bellows 180 from being inhaled into the human body again.

[0048] Furthermore, the one-way diaphragm 332 is initially in a closed state and has a micro mist outlet in the closed state, which facilitates judging whether the liquid medicine has been atomized successfully.

[0049] In a further embodiment, the hard segment 310 is threadedly connected to the mist outlet pipe 150. Specifically, the inner wall of the connecting tube 312 of the hard segment 310 is provided with an internal thread 3121, and the outer wall of the sliding tube 151 of the mist outlet pipe 150 is provided with an external thread 1511, so that the hard segment 310 and the mist outlet pipe 150 can be screwed together.

[0050] In a further embodiment, the upper tube body of the inner cup body 200 is hollow inside and penetrates from top to bottom, and a valve-type cup cover (not shown in the figure) is provided on the top of the inner cup body 200. The valve-type cup cover can adjust the size of the opening at the top of the inner cup body 200 to balance the air pressure inside the cup holder 100.

[0051] In a further embodiment, a handle 140 is provided on the cup holder 100 , and the handle 140 and the cup mouth 300 are respectively located on two sides of the cup holder 100 . The handle 140 is provided to facilitate holding the cup holder 100 .

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
