Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically an adjustable breathing and effective cough training mask for COPD patients. Background Technology

[0002] Chronic obstructive pulmonary disease (COPD) is a common respiratory disease characterized by persistent airflow limitation and respiratory symptoms, which severely impacts patients' quality of life. COPD patients often face problems such as difficulty exhaling, airway secretion retention, and weak cough in their daily lives, which can lead to recurrent infections and decreased lung function.

[0003] Breathing training and effective cough training are crucial methods for pulmonary rehabilitation in COPD patients. Breathing training strengthens respiratory muscles and improves ventilation, while effective cough training helps patients clear airway secretions and prevent infection. However, most existing breathing training devices are single-function devices that cannot simultaneously meet the dual needs of breathing training and cough assistance. Furthermore, traditional devices lack expiratory resistance adjustment, making it difficult to personalize settings according to changes in the patient's condition; they also cannot quickly reduce expiratory resistance during cough training, hindering patients from performing effective coughing movements and limiting the training's effectiveness.

[0004] To address the aforementioned problems, this invention proposes an adjustable breathing and effective cough training mask for COPD patients.

[0005] The information disclosed above in this background section is only for enhancing the understanding of the background section of this invention, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide an adjustable breathing and effective cough training mask for COPD patients, which integrates breathing training and cough assistance functions, and has functions such as adjustable expiratory resistance, cough mode switching, and data display, so as to meet the rehabilitation training needs of patients at different stages.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an adjustable breathing and effective cough training mask for COPD patients, comprising:

The manual gear adjustment mechanism is controlled by the gear switching knob. When switched to "cough gear", the baffle opens to form a bypass channel and reduce exhalation resistance. When switched to "training gear", the baffle closes to restore the preset resistance, and the airflow passes only through the variable resistance valve.

[0014] Preferably, a rectangular data display screen is embedded in the upper part of the mask body to display training duration, resistance level, and number of coughs.

[0015] Preferably, the cough assist triggering module is further equipped with an airflow sensor, which is a miniature probe, used to collect airflow data for output to the data display screen.

[0037] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] Example 1:

[0039] Please see Figures 1-5 An adjustable breathing and effective cough training mask for COPD patients, comprising a mask body 1, an adjustable resistance exhalation module 4, and a cough assist triggering module 5.

[0040] The main body of the mask 1 is an arc-shaped transparent structure with a soft sealing pad 2 around the edge, which can conform to the contours of the patient's face to ensure wearing comfort and airtightness. A one-way inhalation valve 3 is located on the left side of the main body of the mask 1, with an inward arrow marked on the valve body to indicate the airflow direction, ensuring that gas enters unidirectionally during inhalation and automatically closes during exhalation. An oxygen inlet port 7 is located on the right side, with a threaded structure for connecting to an oxygen source to meet oxygen therapy needs.

[0041] The adjustable resistance expiratory module 4 is located at the front end of the mask body 1. The shell is a cylindrical hollow structure, with the top connecting to the mask body 1 interface and the bottom serving as the exhalation outlet. The adjustable resistance expiratory module 4 has a resistance adjustment knob 41 on its side, along with a rectangular resistance indicator window 42. The window is marked with resistance levels 1-5, allowing patients or medical staff to select the appropriate resistance according to their training needs. Inside the adjustable resistance expiratory module 4 is a variable resistance valve 43, whose center is fixedly connected to the screw of the resistance adjustment knob 41. Rotating the knob adjusts the variable resistance valve 43 to its closed, partially open, or fully open state, thereby changing the expiratory resistance. The resistance indicator window 42 contains a pointer that, in conjunction with the screw, points to the corresponding resistance level, visually displaying the current resistance level.

[0042] The cough assist trigger module 5 is integrated above the adjustable resistance expiratory module 4 and is a small rectangular structure. The module surface has a gear switching knob 52, labeled "Training Mode" and "Cough Mode". Internally, there is a manual gear adjustment mechanism 53, which is a built-in baffle structure controlled by the gear switching knob 52. When switched to "Training Mode", the baffle is closed, and airflow passes only through the variable resistance valve 43, maintaining the preset expiratory resistance. When switched to "Cough Mode", the baffle is open, forming a large bypass channel, significantly reducing expiratory resistance and facilitating effective cough training for the patient.

[0043] The data display screen 6 is embedded in the upper part of the mask body 1. It is a rectangular display area used to display key parameters such as training duration, current resistance level, and number of coughs, thereby improving the visualization and data management capabilities of training.

[0044] Example 2:

[0045] This embodiment is basically the same as Embodiment 1, except that:

[0046] The cough assist trigger module 5 also includes an airflow sensor 51, which is a miniature probe used to collect airflow data in real time and output it to the data display screen 6. The airflow sensor 51 is a high-precision differential pressure sensor, which can more sensitively detect changes in expiratory airflow. Together with the data display screen 6, it can draw expiratory flow curves in real time, helping patients to observe the training effect more intuitively.

[0047] Working principle:

[0048] Breathing Training: The patient inhales air or oxygen through the one-way inhalation valve 3 on the left side of the mask body 1. The one-way valve design ensures that gas can only enter the mask, preventing backflow of exhaled gas. Exhaled gas enters the adjustable resistance expiratory module 4. This module contains a variable resistance valve 43, the opening of which is controlled by a resistance adjustment knob 41 via a lead screw. When the knob is rotated, the valve can be continuously adjusted from closed to fully open, thereby changing the magnitude of expiratory resistance. The resistance indicator window 42 contains a pointer that is linked to the lead screw, pointing to a resistance scale of 1-5, allowing users or medical staff to select the appropriate training intensity according to the patient's condition stage.

[0049] Cough Training: When the patient needs to cough, the mode can be switched to "Cough Mode" using the gear switching knob 52 on the surface of the cough assist trigger module 5. After switching, the internal baffle of the manual gear adjustment mechanism 53 opens, forming a bypass channel, significantly reducing expiratory resistance, making it easier for the patient to perform a quick and forceful exhalation, simulating an effective cough. After coughing, the knob is switched back to "Training Mode," the baffle closes, and the airflow passes through the variable resistance valve 43 again, restoring the preset expiratory resistance, and breathing training continues.

[0050] The cough assist trigger module 5 is equipped with an airflow sensor 51, which collects expiratory airflow data in real time. The data is transmitted to the data display screen 6, which displays key parameters such as training duration, current resistance level, and number of coughs in real time, helping patients to monitor their training status, and allowing medical staff to assess the training effect.

[0051] The right side of the mask has an oxygen inlet port 7, which can be connected to an oxygen source to meet the needs of oxygen therapy and improve training safety.

[0052] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0053] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0054] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
