Description

Technical Field

[0001] This utility model relates to the field of pulmonary function rehabilitation training technology, specifically a pulmonary function training device. Background Technology

[0002] Lung function training is designed for patients with lung diseases or those who need to improve their lung function. Through training, it enhances the strength and endurance of respiratory muscles, improves lung ventilation and gas exchange, thereby restoring normal respiratory function and improving the patient's quality of life.

[0003] Chinese patent CN220175987U discloses a portable pulmonary function rehabilitation trainer. This trainer controls the number of exhaust slots connected to the outside by rotating a threaded frame, thereby controlling the amount of air discharged. This allows the resistance encountered by the patient when exhaling and pushing the sliding plate upward to be adjusted, enabling the patient to adjust the intensity of the exercise according to their actual needs, thus improving the patient's rehabilitation speed.

[0004] However, in the aforementioned patent, since the trachea and exhalation frame are an integrated structure, medical staff need to disinfect the exhalation frame before giving the training device to other patients, which increases the workload of medical staff. In addition, the surface of the exhalation frame is prone to dust or contact with other objects, which not only affects the user experience but also increases the risk of cross-infection. Utility Model Content

[0005] The purpose of this invention is to provide a lung function training device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows.

[0007] A lung function training device includes an exhalation cylinder and a sealing cap. An air inlet tube is installed on the outer surface of the exhalation cylinder, and a connecting tube is installed at the end of the air inlet tube via a connecting mechanism. A housing is installed at the end of the connecting tube, and the sealing cap matches the housing. A corrugated hose is connected inside the connecting tube, and an exhalation frame is installed at the end of the corrugated hose, and the exhalation frame matches the interior of the housing.

[0008] Therefore, the connecting mechanism allows for convenient and quick replacement of the exhalation frame, ensuring that each patient has their own exhalation frame component. When using the exhalation pump, patients simply need to attach their own exhalation frame component to the inhalation tube. This not only avoids the discomfort caused by alternating use but also reduces the workload of medical staff who frequently need to disinfect, thus alleviating their burden. Furthermore, when not in use, the exhalation frame can be retracted into the shell, and the sealing cap can be placed on the shell for storage, preventing dust accumulation and contact with other objects, improving the user experience, and avoiding the risk of cross-infection.

[0009] Furthermore, the connecting mechanism includes a connecting tube installed at the end of the connecting pipe, a positioning hole is provided on the outer surface of the connecting tube, a pipe body is installed on the outer surface of the air intake pipe, a positioning rod is inserted inside the pipe body and the positioning rod matches the positioning hole, a shoulder is provided on the outer surface of the positioning rod, a spring is sleeved on the outer surface of the positioning rod, and the two ends of the spring abut against the shoulder and the inner wall of the pipe body, respectively.

[0010] Furthermore, a limiting groove is provided on the inner wall of the shell, and a limiting slider is installed on the outer surface of the exhalation frame, with the limiting slider set in the limiting groove.

[0011] Furthermore, a paddle is installed inside the exhalation frame.

[0012] Furthermore, a finger ring is installed at the end of the positioning rod away from the positioning hole.

[0013] Furthermore, a sealing gasket is bonded to the end of the intake pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] 1. This utility model, through the setting of the connecting mechanism, allows for convenient and quick replacement of the exhalation frame, so that each patient has an exhalation frame component. When using the exhalation pump, patients only need to install their own exhalation frame component on the inhalation tube. This not only avoids the aversion caused by alternating use, but also reduces the workload of medical staff in frequent disinfection, thus alleviating their workload.

[0016] 2. When not in use, the exhalation frame can be retracted into the shell, and then the sealing cap can be placed on the shell to store the exhalation frame, avoiding the adhesion of dust and the possibility of contact with other objects, improving the user experience, and avoiding the risk of cross-infection.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0024] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] like Figure 1-4As shown, a lung function training device includes an exhalation cylinder 100 and a sealing cap 106. An inlet pipe 101 is mounted on the outer surface of the exhalation cylinder 100. A connecting pipe 102 is mounted to the end of the inlet pipe 101 via a connecting mechanism 200. A housing 103 is mounted to the end of the connecting pipe 102, and the sealing cap 106 matches the housing 103. A corrugated hose 104 is connected inside the connecting pipe 102. An exhalation frame 105 is mounted to the end of the corrugated hose 104, and the exhalation frame 105 matches the interior of the housing 103.

[0026] During use, each patient is provided with an exhalation frame 105. When lung function training is required, simply connect the connecting tube 102 to the inlet tube 101 via the connecting mechanism 200, and then pull the exhalation frame 105 out of the housing 103 using the elasticity of the corrugated hose 104. This not only avoids the aversion caused by alternating use, but also reduces the workload of medical staff in frequent disinfection, thus alleviating their burden. After training, the patient removes the connecting tube 102 from the inlet tube 101 via the connecting mechanism 200, then retracts the exhalation frame 105 into the housing 103, and finally covers the housing 103 with the sealing cap 106. This allows for the storage of the exhalation frame 105, preventing dust adhesion and contact with other objects, improving the user experience, and avoiding the risk of cross-infection.

[0027] Specifically, the connecting mechanism 200 includes a connecting tube 201 installed at the end of the connecting pipe 102. A positioning hole 202 is provided on the outer surface of the connecting tube 201. A pipe body 203 is installed on the outer surface of the air intake pipe 101. A positioning rod 204 is inserted inside the pipe body 203, and the positioning rod 204 matches the positioning hole 202. A shoulder 205 is provided on the outer surface of the positioning rod 204. A spring 206 is sleeved on the outer surface of the positioning rod 204, and both ends of the spring 206 abut against the shoulder 205 and the inner wall of the pipe body 203, respectively. When the connecting pipe 102 is removed from the end of the air intake pipe 101, simply pull the positioning rod 204 to pull its end out of the positioning hole 202. The fixing of the connecting tube 201 can be released, and then the connecting tube 201 can be directly pulled out from the air inlet tube 101, thus completing the disassembly of the connecting tube 102. When installing the connecting tube 102 and the air inlet tube 101, the positioning rod 204 can be pulled out from the air inlet tube 101 first, and then the connecting tube 201 can be inserted into the air inlet tube 101. When the positioning hole 202 corresponds to the position of the positioning rod 204, the positioning rod 204 can be released. Under the elastic force of the spring 206, the positioning rod 204 can be firmly inserted into the positioning hole 202, thus completing the installation of the connecting tube 102. Therefore, it can greatly facilitate patients to disassemble and assemble the exhalation frame 105 components themselves.

[0028] Specifically, a limiting groove 300 is provided on the inner wall of the housing 103, and a limiting slider 301 is installed on the outer surface of the exhalation frame 105. The limiting slider 301 is set in the limiting groove 300. Through the setting of the limiting groove 300 and the limiting slider 301, the movement trajectory of the exhalation frame 105 can be guided, thereby ensuring that the corrugated hose 104 can extend and retract smoothly. In addition, there is a large friction between the limiting groove 300 and the limiting slider 301, which can roughly fix the position of the exhalation frame 105, prevent it from sliding randomly, and improve stability.

[0029] Specifically, a lever 400 is installed inside the exhalation frame 105. Since the exhalation frame 105 retracts into the housing 103, the lever 400 provides a force point, making it easy to pull the exhalation frame 105 out of the housing 103.

[0030] Specifically, a finger ring 500 is installed at the end of the positioning rod 204 away from the positioning hole 202. By setting the finger ring 500, a finger can be passed through the finger ring 500 and then pulled on the positioning rod 204, which can prevent the hand from slipping.

[0031] Specifically, a sealing gasket 600 is bonded to the end of the air intake pipe 101. The sealing gasket 600 provides a seal at the connection between the connecting pipe 102 and the air intake pipe 101, thus preventing air leakage during training.

[0032] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
