Abstract

Technical Field
[0001] This utility model relates to the field of respiratory function training devices, and in particular to a passive respiratory function training device that displays vital capacity. Background Technology
[0002] The Department of Respiratory Medicine belongs to the Department of Clinical Medicine and is a secondary discipline under Internal Medicine. It deals with infectious diseases, including upper respiratory tract infections (the common cold), as well as acute bronchitis, chronic bronchitis, pneumonia, lung abscess, bronchiectasis, and tuberculosis. Respiratory system diseases are the main causes affecting lung function and respiratory muscle strength. Examples include chronic obstructive pulmonary disease (COPD), emphysema, and bronchial asthma. These diseases lead to breathing difficulties and airflow obstruction, impacting patients' quality of life.
[0003] Breathing training can effectively improve patients' lung function, strengthen respiratory muscles, and increase physiological indicators such as vital capacity and maximum expiratory flow rate. Respiratory rehabilitation training includes lung volume training, respiratory muscle strength training, and airway management training.
[0004] For example, the prior art Chinese patent publication number "CN116966509 A" provides a respiratory medicine pulmonary function rehabilitation physiotherapy training device, including a main unit shell, a control motherboard installed on the side of the main unit shell and electrically connected to an external power supply, a breathing port fixed through one side of the upper end of the main unit shell, and a breathing connection tube embedded in the breathing port, and a cleaning mechanism, an inhalation cylinder and an inhalation cylinder are respectively installed inside the main unit shell.
[0005] This device uses inhalation and exhalation for exercise. When inhaling or exhaling, the small ball moves upward and is detected by a distance sensor. The processing module processes and analyzes the data to obtain the lung capacity value, which is stored in the storage module and sent to the display module for display. At the same time, it is sent to the medical terminal via the wireless communication module, realizing autonomous data recording, storage and transmission. Medical staff do not need to stand by to record, reducing the workload of medical personnel, and there is no need to worry about water mist.
[0006] Existing passive lung capacity display respiratory function training devices have a relatively simple breathing cylinder structure during breathing exercises. It is a single unit, which is inconvenient for disassembly, installation, cleaning and maintenance. In addition, there are few breathing exercise interfaces, which makes it inconvenient for multiple people to breathe at the same time and reduce mutual interference. Furthermore, the connection between the air tube used for breathing exercises and the breathing cylinder is not tight enough, which can easily lead to air leakage or even separation when the air tube is dragged, and it fails to provide stable clamping.
[0007] Therefore, a passive respiratory function training device for displaying lung capacity is proposed. Utility Model Content
[0008] The purpose of this invention is to address the shortcomings of existing technologies, such as insufficient tightness between the air tube and the breathing cylinder used for breathing exercises, which can easily lead to air leakage or even separation when the air tube is dragged, and failure to achieve stable clamping. Therefore, this invention proposes a passive respiratory function training device that displays lung capacity.
[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0011] Furthermore, a first vent hole is opened on the outer side of the container, and a pad is fixed at its bottom end. The plug is tightly connected to the inner top of the breathing tube and is located at the bottom end of the cover plate.
[0012] Furthermore, a support plate is fixed at the top of the cover plate and outside the first connecting pipe. An installation rod slides through the surface of the support plate. The inner end of the installation rod is fixedly connected to the clamping plate. A limit plate is fixed at the outer end of the installation rod and outside the support plate.

[0013] Furthermore, the cover plate is a circular plate structure and is horizontally arranged, the first connecting pipe is vertically arranged, the air guide pipe is a rubber hose, the support plate is a rectangular plate structure and is vertically arranged, the mounting rod is a rectangular rod structure and is horizontally arranged, and the clamping plate is a rectangular plate structure and is vertically arranged.
[0014] Furthermore, the surface of the breathing tube has a second ventilation hole, and a second connecting tube is fixed at its bottom end. The second connecting tube communicates with the bottom end of the breathing tube and slides through the bottom end of the container. A nut is connected to the surface of the second connecting tube at the bottom end of the container. The second connecting tube is a round tube with an external threaded surface and is vertically arranged.
[0015] Furthermore, the surface of the spring plate has a third vent hole, and a sponge pad is placed on its top. The first connecting pipe, the sponge pad, the third vent hole and the second connecting pipe are interconnected.
[0016] Furthermore, the spacer has a cross-shaped structure and is vertically arranged; the breathing tube has a cylindrical structure and is vertically arranged, with its top end lower than the top end of the container; and the lifting ring has a circular structure and is vertically arranged.
[0017] Furthermore, the first spring is vertically positioned, and the spring plate is a circular plate structure and is horizontally positioned.
[0018] The passive respiratory function training device for displaying vital capacity proposed in this utility model has the following advantages:

Furthermore, the bottom of each breathing cylinder is detachably connected via a second connecting pipe, and its top is detachably connected to a cover plate via a first connecting pipe. A stopper cap is detachably installed on the top of each breathing cylinder. This facilitates the disassembly, installation, cleaning, and maintenance of the breathing cylinders, making it easy to remove the sponge and clean the inside of the breathing cylinders. Additionally, the top of the container has multiple air ducts and breathing masks, allowing multiple people to perform breathing exercises simultaneously without interfering with each other's breathing. Moreover, a single arc-shaped cylinder can be detached for breathing exercises, making this breathing function training device flexible and convenient to use.
[0020] 2. In this utility model, a support plate is fixed at the top of the cover plate, and a clamping plate is elastically installed by an installation rod and a spring.

In this way, the air duct and the first connecting tube can be stably and sealed, avoiding air leakage caused by dragging of the air duct during breathing exercises. Attached Figure Description
