Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a body position-adaptable oxygen atomization inhalation device. Background Art

[0002] At present, the devices used for nebulization therapy in clinical practice mainly include three types based on the principle of nebulization: ultrasonic nebulization, jet nebulization, and vibrating sieve nebulization. Among them, ultrasonic nebulizers are noisy and bulky, and have been gradually eliminated. The cost of micro-grid nebulization equipment and consumables is relatively high. The jet nebulizers used in clinical practice are mainly oxygen nebulizers, which have relatively low consumables, are easy to use, and can take into account the need for oxygen inhalation during treatment, so they are more commonly used.

[0003] Due to the limitations of their disease, some patients are unable to maintain an upright position to receive nebulized inhalation treatment. Regardless of the type of nebulizer device, the drug storage tank is designed to be horizontal. The liquid level in the drug storage tank tilts due to changes in the patient's body position. When the tilt angle is too large, the drug liquid cannot fully enter the injection cavity, resulting in the inability to produce the required amount of mist, which in turn affects the effect of nebulizer treatment. Utility Model Content

[0004] The purpose of the utility model is to provide an oxygen atomization inhalation device that can adapt to body posture, and effectively solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions.

[0006] A body position-adaptive oxygen atomization inhalation device comprises a spherical medicine tank, a buoyant atomization core, an injection nozzle and a septum. The buoyant atomization core is arranged in the spherical medicine tank. A through injection cavity is provided in the buoyant atomization core. A plurality of liquid inlet cavities connected with the injection cavity are evenly distributed on the outer edge wall of the buoyant atomization core. The top of the buoyant atomization core is provided with an injection nozzle connected with the injection cavity. A septum is provided on the buoyant atomization core and above the injection nozzle. The septum faces the injection port of the injection nozzle. When liquid medicine is injected into the spherical medicine tank, the buoyant atomization core can be suspended in the liquid medicine and partially exposed above the liquid surface. At the same time, each liquid inlet cavity is always immersed in a position below the liquid surface.

[0007] It can be seen that when the patient's body position changes and the position of the spherical medicine tank tilts, resulting in the tilt of the liquid level in the spherical medicine tank, under the action of gravity and buoyancy, the buoyant atomization core as a whole adaptively adjusts following the change of the liquid level, ensuring that the buoyant atomization core always remains perpendicular to the liquid surface, and the liquid inlet cavity around the buoyant atomization core is always immersed below the liquid surface, thereby ensuring that the liquid medicine can be fully inhaled into the injection cavity through the liquid inlet cavity for injection and atomization, thereby ensuring that a good atomization treatment effect can be provided when the patient's body position changes, and the integrated structure of gas jet, drug inhalation, and liquid medicine impact maintains the consistency of the three in adapting to changes in patient body position.

[0008] Furthermore, the snorkeling atomization core consists of a floating part and a counterweight part. The floating part is fixed above the counterweight part. There is a connecting seam between the floating part and the counterweight part. The injection cavity is arranged together in the floating part and the counterweight part. The liquid inlet cavity is arranged on the counterweight part. The injection nozzle is fixed on the floating part. When the medicine liquid is injected into the spherical medicine tank, the liquid level of the medicine always corresponds to the height position of the connecting seam.

[0009] When the patient's body position changes and causes the liquid level in the spherical medicine tank to tilt, the buoyancy of the floating part and the gravity of the counterweight part can make the snorkeling atomization core as a whole always remain perpendicular to the liquid surface, thereby ensuring that the liquid inlet cavity is always submerged below the liquid surface, making it easier to effectively suck the medicine into the injection cavity for atomization treatment.

[0010] Furthermore, a bracket is fixed on the top of the floating part, and the spacer is installed on the top of the bracket.

[0011] The diaphragm is installed above the floating part by using a bracket, and the diaphragm is supported and suspended above the injection nozzle, so that a certain space is left between the diaphragm and the injection nozzle, so that the liquid medicine that impacts the diaphragm at high speed is atomized and dispersed around to form good atomization conditions.

[0012] Furthermore, an air inlet is provided on the spherical medicine tank, and a mist outlet is provided on a side of the spherical medicine tank opposite to the air inlet. The air inlet is communicated with the injection cavity through an air guide hose.

[0013] The air inlet is connected to the oxygen supply tube, and the mist outlet is connected to the atomizing oxygen inhalation tube. The air inlet introduces a high-speed oxygen flow into the air guide hose, and the high-speed oxygen flow is transported to the injection cavity through the air guide hose to provide power for the high-speed impact of the medicine liquid. In addition, the atomized medicine liquid and oxygen flow into the atomizing oxygen inhalation tube through the mist outlet to provide the patient with atomized oxygen inhalation quality. The air guide hose adopts a soft tube with the characteristics of easy bending and deformation, so as to adapt to the position change of the snorkeling atomization core when the patient's body position changes.

[0014] Furthermore, one end of the air guide hose is connected to the snorkeling atomization core and is connected to the injection cavity, and the other end is connected to the air inlet. A micro spring is provided on the outside of the air guide hose, one end of the micro spring is fixed to the outer wall of the counterweight part, and the other end is fixed to the inner wall of the spherical medicine tank.

[0015] By arranging a micro spring on the gas guide hose and utilizing the elastic support effect of the micro spring, it is possible to prevent the gas guide hose from being excessively bent and causing blockage, thereby affecting the normal flow of oxygen.

[0016] Furthermore, a limit stop ring is fixed on the inner wall of the spherical medicine tank near the mist outlet.

[0017] By setting a limit ring near the mist outlet in the spherical medicine tank, it is possible to prevent the snorkeling atomization core from excessively displacing and blocking the mist outlet, thereby affecting the normal flow of atomized medicine liquid and oxygen into the mist outlet.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0019] 1. When the patient's body position changes and the position of the spherical medicine tank is tilted, resulting in the tilt of the liquid level in the spherical medicine tank, the utility model makes the buoyant atomization core as a whole adaptively adjust following the change of the liquid level under the action of gravity and buoyancy, ensuring that the buoyant atomization core always remains perpendicular to the liquid level, and thus the liquid inlet cavity around the buoyant atomization core is always immersed below the liquid level, thereby ensuring that the medicine can be fully inhaled into the injection cavity through the liquid inlet cavity for injection and atomization, thereby ensuring that a good atomization treatment effect can be provided when the patient's body position changes, and the integrated structure of gas jet, medicine inhalation, and medicine liquid impact maintains the consistency of the three in adapting to changes in the patient's body position.

[0020] 2. The present invention prevents the air guide hose from being blocked by excessive bending and affecting the normal flow of oxygen by utilizing the elastic support effect of a micro spring on the air guide hose. A limit ring is provided near the mist outlet in the spherical medicine tank to prevent the snorkeling atomization core from excessive displacement, thereby blocking the mist outlet and affecting the normal flow of atomized liquid and oxygen into the mist outlet.

[0025] 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 embodiments described 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 efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 3 The utility model provides a body position adaptive oxygen atomization inhalation device, including a spherical medicine tank 1, a buoyant atomization core 2, an injection nozzle 4 and a septum 5. The buoyant atomization core 2 is arranged in the spherical medicine tank 1, and a through injection cavity 3 is provided in the buoyant atomization core 2. A plurality of liquid inlet cavities 221 connected with the injection cavity 3 are evenly distributed on the outer edge wall of the buoyant atomization core 2. The top of the buoyant atomization core 2 is provided with an injection nozzle 4 connected with the injection cavity 3. A septum 5 is provided on the buoyant atomization core 2 and above the injection nozzle 4. The septum 5 is opposite to the injection port of the injection nozzle 4. When the medicine liquid is injected into the spherical medicine tank 1, the buoyant atomization core 2 can be suspended in the medicine liquid and partially exposed above the liquid surface. At the same time, each liquid inlet cavity 221 is always immersed in a position below the liquid surface.

[0027] When using the main body position-adaptive oxygen atomization inhalation device, by introducing a high-speed oxygen flow into the injection cavity 3, the medicine liquid in the spherical medicine tank 1 is sucked into the injection cavity 3 from the liquid inlet cavity 221 around the snorkeling atomization core 2 under the action of the Venturi principle, and is sprayed onto the septum 5 at high speed through the injection nozzle 4. By colliding with the septum 5, the medicine liquid is atomized and mixed with oxygen for the patient to inhale by atomization.

[0028] When the patient's body position changes and the position of the spherical medicine tank 1 tilts, resulting in the tilt of the liquid level in the spherical medicine tank 1, under the action of gravity and buoyancy, the buoyant atomization core 2 as a whole adaptively adjusts following the change of the liquid level, ensuring that the buoyant atomization core 2 always remains perpendicular to the liquid surface, and thus the liquid inlet cavity 221 around the buoyant atomization core 2 is always immersed below the liquid surface, thereby ensuring that the liquid medicine can be fully inhaled into the injection cavity 3 through the liquid inlet cavity 221 for injection and atomization, thereby ensuring that a good atomization treatment effect can be provided when the patient's body position changes, and the integrated structure of gas jet, drug inhalation, and liquid medicine impact maintains the consistency of the three in adapting to changes in patient body position.

[0029] The buoyancy atomization core 2 is composed of a floating part 21 and a counterweight part 22. The floating part 21 is made of buoyant material, and the counterweight part 22 is sunk below the liquid surface. There is a connecting seam 23 between the floating part 21 and the counterweight part 22. The injection cavity 3 is arranged together in the floating part 21 and the counterweight part 22. The liquid inlet cavity 221 is arranged on the counterweight part 22, and the injection nozzle 4 is fixed on the floating part 21. When the medicine liquid is injected into the spherical medicine tank 1, the liquid level of the medicine liquid always corresponds to the height position of the connecting seam 23. When the patient's body position changes and the liquid level in the spherical medicine tank 1 tilts, the buoyancy of the floating part 21 and the gravity of the counterweight part 22 can make the buoyancy atomization core 2 as a whole always remain perpendicular to the liquid surface, thereby ensuring that the liquid inlet cavity 221 is always submerged below the liquid surface, so as to effectively suck the medicine liquid into the injection cavity 3 for atomization treatment.

[0030] Specifically, a bracket 51 is fixed on the top of the floating part 21, and the diaphragm 5 is installed on the top of the bracket 51. The diaphragm 5 is installed above the floating part 21 using the bracket 51, and the diaphragm 5 is supported and suspended above the injection nozzle 4, so that a certain space is left between the diaphragm 5 and the injection port of the injection nozzle 4, so that the liquid medicine that impacts the diaphragm 5 at high speed is atomized and then dispersed to the surroundings to form good atomization conditions.

[0031] Specifically, an air inlet 6 is provided on the spherical medicine tank 1, and a mist outlet 7 is provided on the side of the spherical medicine tank 1 opposite to the air inlet 6. The air inlet 6 is connected to the injection cavity 3 through an air guide hose 8. The air inlet 6 is connected to the oxygen supply pipe, and the mist outlet 7 is connected to the atomizing oxygen inhalation pipe. The high-speed oxygen flow is introduced into the air guide hose 8 by the air inlet 6, and the high-speed oxygen flow is transported to the injection cavity 3 through the air guide hose 8 to provide power for the high-speed impact of the medicine liquid. In addition, the atomized medicine liquid and oxygen flow into the atomizing oxygen inhalation pipe through the mist outlet 7 to provide the patient with atomized oxygen inhalation quality.

[0032] In addition, the air guide hose 8 is made of a soft tube, which is easy to bend and deform, thereby adapting to the position change of the snorkeling atomization core 2 when the patient's body position changes.

[0033] Specifically, one end of the air guide hose 8 is connected to the snorkeling atomization core 2 and is connected to the injection cavity 3, and the other end is connected to the air inlet 6. A micro spring 81 is provided on the outside of the air guide hose 8, and one end of the micro spring 81 is fixed to the outer wall of the counterweight part 22, and the other end is fixed to the inner wall of the spherical medicine tank 1.

[0034] By sleevedly arranging the micro spring 81 on the air guide hose 8 and utilizing the elastic support effect of the micro spring 81 , it is possible to prevent the air guide hose 8 from being excessively bent and causing blockage, thereby affecting the normal flow of oxygen.

[0035] In addition, the length of the air guide hose 8 is greater than one quarter of the inner perimeter of the cross section of the spherical medicine tank 1, which can ensure that the snorkeling atomizer core 2 can move in a direction of 90 degrees.

[0036] Specifically, a limit stop ring 9 is fixed on the inner wall of the spherical medicine tank 1 near the mist outlet 7. By setting the limit stop ring 9 near the mist outlet 7 in the spherical medicine tank 1, excessive displacement of the snorkeling atomization core 2 can be avoided to block the mist outlet 7 and affect the normal flow of the atomized medicine liquid and oxygen into the mist outlet 7.

[0037] The above is a detailed description of the present invention in conjunction with specific embodiments, and the specific implementation methods of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and the performance or use are the same, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
