Description

Technical Field

[0001] This utility model relates to the field of lung capacity training devices, and more specifically, to a respiratory rehabilitation lung capacity training device. Background Technology

[0002] In recent years, the spread of influenza has been quite severe, leading to a significant increase in patients with respiratory infections in hospitals. After a period of treatment, these patients are transferred to general wards for observation. Lung capacity refers to the volume of air that can be exhaled after a maximal inhalation, comprising tidal volume, inspiratory reserve volume (IRV), and expiratory reserve volume (ERV). Tidal volume is the amount of air inhaled or exhaled during one respiratory cycle. The maximum amount of air inhaled beyond the tidal volume is the inspiratory reserve volume, and the maximum amount of air exhaled beyond the tidal volume is the expiratory reserve volume. The amount of air remaining in the lungs after a maximal exhalation is the residual volume. Lung capacity varies considerably from person to person, influenced by factors such as age, sex, body size, respiratory muscle strength, and lung and thoracic elasticity. Generally speaking, the stronger the body, the greater the lung capacity. Lung capacity is closely related to human respiration, hence this research provides a respiratory rehabilitation lung capacity training device. Utility Model Content

[0017] 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.

[0018] This embodiment discloses a respiratory rehabilitation lung capacity trainer, specifically designed to meet the lung capacity training needs of patients recovering from respiratory infections. By optimizing the mask structure, airflow adjustment components, and wearing and fixing method, this trainer achieves precise control of the patient's breathing airflow while ensuring respiratory hygiene and wearing comfort, helping patients gradually improve their lung capacity. It is suitable for patients in general hospital wards during the observation period and for people undergoing respiratory rehabilitation at home. Specific settings are as follows.

[0019] like Figure 1 , Figure 4 As shown, the core component of the training device is the face mask 1, which is injection molded from food-grade PP material and conforms to the curves of the mouth and nose area of ​​an adult face. A sealing gasket 9, made of medical-grade silicone, is fitted onto the outer edge of the face mask 1 and secured to it via an interference fit. The sealing gasket 9 effectively fills the gap between the face mask 1 and the facial skin, preventing airflow leakage during training and ensuring the accuracy of the training effect. Simultaneously, the silicone material reduces pressure on the skin, improving comfort during extended wear.

[0020] like Figure 3 As shown, the mask 1 has a removable inner liner 2 made of ABS plastic, with an arc-shaped structure that fits the inner wall of the mask 1. A rubber pad 3 is adhered to the side of the inner liner 2 closest to the face. The rubber pad 3 is made of soft medical-grade rubber and has a concave arc design corresponding to the mouth and nose area, which further enhances the facial fit and prevents the hard edges of the inner liner 2 from directly contacting the skin and causing discomfort. Symmetrically integrated diverting blades 4 are formed on both sides of the inner liner 2. The diverting blades 4 are inclined and their function is to divert and guide the airflow exhaled by the patient, preventing the airflow from concentrating and impacting the inner wall of the mask 1, thus avoiding turbulence noise, and ensuring more even contact between the airflow and subsequent components.

[0021] To achieve a detachable connection between the inner liner 2 and the face mask 1, two symmetrical locking blocks 5 are integrally formed on the side of the inner liner 2 away from the rubber pad 3. The locking blocks 5 extend to one side of the inner wall of the face mask 1 and engage with a pre-set locking groove on the inner wall of the face mask 1. This locking structure facilitates the regular removal of the inner liner 2 for cleaning and disinfection by medical staff or patients, reducing the risk of cross-infection.

[0022] like Figure 2 , Figure 4 As shown, filter cartridges 13 are symmetrically installed on both sides of the mask 1. These cartridges are hollow inside and open at both ends. An intake valve 6 for flow regulation is embedded within the filter cartridge 13. An adjustable valve core is installed inside the valve core; rotating the valve core changes the cross-sectional area of ​​the intake channel, achieving multi-level adjustment of the intake flow. Medical personnel can precisely adjust the opening of the intake valve 6 according to the patient's rehabilitation stage and vital capacity level, providing the patient with a gradual increase in training intensity.

[0023] Two filter cartridges 13 are threadedly connected to the ends furthest from the mask 1, with air intake hoods 7 being flared structures. The larger diameter end of each air intake hood 7 faces outward, increasing the air intake area and reducing air intake resistance. Each air intake hood 7 has a baffle 8 connected to its outer edge via a hinge. The size of the baffle 8 matches the larger diameter end of the air intake hood 7. When the patient inhales, the airflow pushes the baffle 8 outward, ensuring normal air intake. When exhaling, the airflow pressure causes the baffle 8 to adhere to the edge of the air intake hood 7, closing the air intake channel and forcing the exhaled airflow to exit only through the pre-set exhaust structure of the mask 1, thus forming a unidirectional airflow circulation and ensuring the stability and controllability of the breathing airflow during training.

[0024] like Figure 1 , Figure 2 , Figure 4 As shown, several first buckles 11 are symmetrically fastened to the outer wall of the mask 1. Each first buckle 11 is movably fastened with a second buckle 12, one end of which is detachably connected to the first buckle 11, and the other end is fixedly connected to the restraint strap 10. The restraint strap 10 is made of high-elastic spandex material, and its vertical cross-section is set in an X shape. Both ends are sewn and fixed to the second buckles 12 on both sides. The X-shaped restraint strap 10 can evenly distribute the wearing pressure to the sides and back of the head, avoiding the pressure on the head caused by traditional headbands. At the same time, the high-elastic material can adapt to patients with different head circumferences, ensuring that the mask 1 remains stable and fits during training and will not shift due to the patient's breathing or slight head movements.

[0025] The specific working principle is as follows: This respiratory rehabilitation lung capacity trainer achieves lung capacity training through unidirectional airflow control and intake flow rate adjustment. After the patient wears the mask 1, during inhalation, the baffle 8 on the intake hood 7 opens, and external air enters the filter cartridge 13 through the intake hood 7. After the flow rate is adjusted by the intake valve 6, it enters the interior of the mask 1 to meet the patient's inhalation needs. During exhalation, the baffle 8 closes, and the exhaled air cannot be discharged from the intake hood 7. It can only be discharged through the pre-set exhaust channel of the mask 1 (not shown in the attached diagram, but can be added according to the actual design, such as the one-way exhaust valve at the bottom of the mask 1). At this time, the patient needs to overcome the resistance of the exhaust channel or the reverse pressure of the intake valve 6 to exhale, thereby exercising the respiratory muscle strength. At the same time, the diverting blades 4 on both sides of the inner liner 2 can evenly distribute the exhaled airflow to avoid airflow turbulence affecting the training experience. The flow rate adjustment function of the intake valve 6 can adjust the expiratory resistance according to the patient's rehabilitation progress, gradually improving the patient's lung capacity level.

[0026] Furthermore, based on the patient's lung capacity test results and rehabilitation stage, the air intake valve 6 inside the rotating filter cartridge 13 is adjusted to the corresponding flow rate. At the same time, the patient covers the mouth and nose area with the mask 1, ensuring that the sealing pad 9 fits snugly against the face. The X-shaped restraint strap 10 is then placed on the head, and the position of the second buckle 12 on the first buckle 11 is adjusted to ensure that the restraint strap 10 is properly tightened, ensuring that the mask 1 does not shift or leak air.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
