Description

Technical Field

[0001] The utility model relates to the technical field of drug administration and breathing training instruments, in particular to a drug administration and breathing training device capable of atomization. Background Art

[0002] When a person inhales normally, the diaphragm and the external intercostal muscles contract. When inhaling forcefully, the inhalation auxiliary muscles, such as the trapezius and scalene muscles, are also needed to assist. The contraction of these muscles causes the chest to rise and the chest cavity space to expand to the limit, so the inspiratory muscles need to be trained. Most inhalation trainers on the market use the basic principle of impedance training. When users inhale through the inhalation trainer, they need to work hard to resist the impedance set by the trainer to increase the strength of the inhalation muscles, thereby increasing the strength and tolerance of the respiratory muscles, improving problems such as dyspnea, improving cardiopulmonary function, and further improving the effectiveness of exercise.

[0003] The human body exhales because the pressure in the lungs is greater than the atmospheric pressure. Normal exhalation does not cause muscle contraction. When the human body exhales forcefully, the internal intercostal muscles and abdominal muscles begin to contract, and the pressure in the lungs increases to the maximum, so that a large amount of carbon dioxide in the body can be exhaled. Exhalation training has a significant effect on the efficiency of gas exchange in the body. In addition, the auxiliary equipment for exhalation training often adds an airway oscillation mechanism, so that patients with chronic lung diseases can achieve the effect of loosening and expectorating phlegm while training their breathing, making the entire treatment process more effective.

[0004] Nebulizer therapy is one of the commonly used treatment methods for respiratory diseases. Nebulizer therapy mainly refers to aerosol inhalation therapy. The so-called aerosol refers to tiny solid or liquid particles suspended in the air. Therefore, nebulizer inhalation therapy uses an atomizing device to disperse the drug into tiny droplets or particles, suspending them in the gas and entering the respiratory tract and lungs to achieve the purpose of humidifying the airway and treating respiratory inflammation.

[0005] The Chinese invention patent (publication number: CN114870359B, publication date: 2023.08.29) discloses a nebulized drug administration breathing training instrument, a ventilating tube for nebulized drug administration breathing training, including a hollow ventilated tube body; the tube body is composed of an air inlet pipe and an air outlet pipe, and a water storage mechanism is arranged at the sleeve joint on the tube body, and the existing condensed water storage mechanism outside the ventilating tube is changed to be arranged inside the ventilating tube, and the pressure-guiding direction and flow path of the humid air flow are changed by the water storage mechanism, so that the water droplets generated by the condensation of the humid air flow are completely retained in the ventilating tube. However, the structure is complicated and inconvenient to disassemble and assemble. It is only used for nebulized drug administration breathing training, and there is still a situation where water droplets enter the pressure-guiding hole in the pressure difference detection component, and the air inlet pipe and the air outlet pipe are not integrated, and there is a situation of air leakage. The nebulized drug administration breathing training device provided by the applicant has a reasonable structure and is easy to disassemble and assemble. The ventilating tube for nebulized drug administration breathing training and the ventilating tube for breathing training can be quickly replaced without replacing the valve head.

[0032] A breathing training device capable of atomizing medication, such as Figure 1-5 The device comprises a housing 1 , a nebulization medication breathing training tube 2 , a breathing training valve head 3 and a nebulization cup 4 .

[0033] like Figure 1 and Figure 2 As shown, one side of the shell 1 includes a first chamber 11, which is a straight tube; the other side includes a pressure measuring device chamber, and a pressure measuring device is installed inside the pressure measuring device chamber; the nebulization drug administration breathing training tube 2 includes an air inlet pipe 21 and a training tube 22, and the training tube 22 is an nebulization training tube 221 or a breathing training tube 222, the air inlet pipe 21 is located at the front end of the training tube 22, the air inlet pipe 21 is located on the outside of the shell 1, and the training tube 22 is sleeved inside the first chamber 11 of the shell 1; a slide groove 71 is provided on the shell 1, and a slide rail 72 is provided on the breathing training valve head 3, and the breathing training valve head 3 is detachably slidably arranged at the end of the shell 1 through the slide rail 72 corresponding to the slide groove 71; the nebulizer cup 4 is detachably installed at the bottom of the shell 1, and an nebulizer cup 4 interface channel can be provided at the bottom of the shell 1, and the top of the nebulizer cup 4 can be movably embedded in the interface channel.

[0034] like Figure 3 and Figure 5 As shown, a third sealing ring 12 is arranged at the front end of the housing 1, and the atomized drug administration breathing training tube (2) further comprises a sealing baffle (28), which is arranged on the outer wall of the atomized drug administration breathing training tube (2) and is located between the air inlet pipe (21) and the training tube (22), and the third sealing ring (12) is located at the rear side of the sealing baffle (28). After the atomized drug administration breathing training tube 2 is locked by the limiting mechanism 5, the third sealing ring 12 and the sealing baffle 28 are also closely attached to each other; a first sealing ring 32 is arranged on the breathing training valve head 3, and the end of the training tube 22 is closely attached to the first sealing ring 32; the above structure forms a seal between the third sealing ring 12 and the first sealing ring 32, thereby preventing the training tube 22 from leaking during use.

[0035] like Figure 2 , Figure 3 and Figure 5 As shown, the air intake pipe 21 and the breathing training pipe 222 are hollow straight pipes; a transverse partition 23 is arranged inside the atomization training pipe 221, and the partition 23 divides the atomization training pipe 221 into two independent upper and lower channels, the upper part of the partition 23 is a breathing air training channel 24, and the lower part is an atomization inhalation channel 25, and an atomization interface 26 is arranged at the bottom of the atomization training pipe 221, and the top opening of the atomization cup 4 is connected to the atomization interface 26. This arrangement allows the device to quickly replace different universal pipes, respectively perform atomization drug administration or breathing training, and meet different needs of patients.

[0036] like Figure 2As shown, a one-way valve mechanism 27 for controlling the channel switch is arranged inside the atomizing inhalation channel 25, and the one-way valve mechanism 27 is arranged at the front end of the atomizing interface 26. The one-way valve mechanism 27 includes a flexible movable sheet 272 movably mounted thereon, and the fixed bracket 271 can be fixed on the partition 23 by mortise and tenon. The flexible movable sheet 272 can be made of flexible plastic or silicone material and made into an umbrella shape, or a T shape, or a buckle shape or a shape that conforms to the atomizing inhalation channel 25. When the atomizing drug is inhaled, the main body of the one-way valve mechanism 27, i.e., the flexible movable sheet 272, is forced to tilt toward one side of the air inlet pipe 21 by the positive force of the inhalation negative pressure, and the channel is opened; when no inhalation is performed, the flexible movable sheet 272 returns to the initial position and fits with the air vent of the fixed bracket 271. When subjected to the reaction force of exhalation, the flexible movable sheet 272 and the air vent fit more closely, ensuring that the gas can only flow in one direction.

[0037] like Figure 2 and Figure 4 As shown, the breathing training valve head 3 includes a rear shell 31, a first sealing ring 32, an inner wall 33 of the pressure-taking cavity, a second sealing ring 34, a middle shell 35, a blade 36 and a front shell 37, and the front shell 37 can also be equipped with a label 38; wherein, the end of the training tube 22 is inserted into the rear shell 31 and fits tightly with the first sealing ring 32, which can prevent the breathing training valve head 3 from shifting sideways during use, thereby locking the breathing training valve head 3; at least one pressure-taking port is provided in the middle and upper part of the inner wall 33 of the pressure-taking cavity, which can prevent water vapor and condensed water from entering the pressure-taking port. An annular pressure-taking chamber 332 is formed between the inner wall 33 of the pressure-taking cavity and the middle shell 35, and the pressure-taking port is connected to the pressure-taking chamber 332. A pressure-taking channel is provided on the middle shell 35, and the pressure-taking channel connects the pressure-taking chamber 332 and the pressure measuring device chamber, and the pressure-taking channel and the pressure-taking port are not on the same axis, which can prevent water vapor and condensed water from blocking the pressure-taking channel and causing the pressure measuring device to malfunction.

[0038] Furthermore, the pressure taking port is arranged at the top of the inner wall 33 of the pressure taking cavity, and the pressure taking channel is arranged horizontally.

[0039] Furthermore, the device also includes a medication assessment valve head, which can be replaced with the breathing training valve head 3 and is detachably slidably arranged at the end of the housing 1. The medication assessment valve head can measure the suction force of the patient, and give different types of medicines according to the suction parameter range of the patient to achieve effective medication. The two valve heads can be used interchangeably according to needs.

[0040] like Figure 1 and Figure 2As shown, the housing 1 and the training tube 22 can also be locked by a limiting mechanism 5, which can prevent the atomization drug administration breathing training tube 2 from moving during use. A locking tube slot 51 is provided on the inner wall of the first chamber 11 of the housing 1, and the locking tube slot 51 is in a broken line shape. A locking tube clamping point 52 is provided on the outer wall of the training tube 22. The locking tube slot 51 and the locking tube clamping point 52 constitute the limiting mechanism 5. In the locked state, the locking tube clamping point 52 is embedded in the end section of the locking tube slot 51, and the end section of the locking tube slot 51 is in the horizontal direction. Only by rotating the atomization drug administration breathing training tube 2 can the locking tube clamping point 52 be moved out to unlock.

[0041] like Figure 1 and Figure 3 As shown, the sleeve connection direction of the atomized drug administration breathing training tube 2 is determined by the anti-reverse insertion mechanism 6 between the housing 1 and the training tube 22, which can prevent the atomized drug administration breathing training tube 2 from being incorrectly installed. An anti-reverse insertion slot 61 is provided on the inner wall of the first chamber 11 of the housing 1, and a guide protrusion 62 is provided on the outer wall of the training tube 22. The anti-reverse insertion slot 61 and the guide protrusion 62 constitute the anti-reverse insertion mechanism 6. The width of the guide protrusion 62 at one end away from the air inlet pipe 21 gradually narrows, so that it has a guiding function; the width of the anti-reverse insertion slot 61 is greater than the guide protrusion 62, so that the guide protrusion 62 can be displaced in the lateral direction in the anti-reverse insertion slot 61, thereby cooperating with the use of the limiting mechanism 5.

[0042] One end of the guide protrusion 62 close to the air inlet pipe 21 is connected to the sealing baffle 28 , and a gap is left between the locking tube clamping point 52 and the sealing baffle 28 .

[0043] The front end of the air inlet pipe 21 can be movably sleeved with a mouthpiece, and the mouthpiece can be disassembled, washed and replaced after use.

[0044] The above is a description of the embodiments of the utility model. Through the above description of the disclosed embodiments, professionals and technicians in the field can implement or use the utility model. Various modifications to these embodiments will be obvious to professionals and technicians in the field. The general principles defined in this article can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to these embodiments shown in this article, but will conform to the widest range consistent with the principles and novelties disclosed in this article.
