Description

Technical Field

[0001] The utility model relates to an effective cough detection device, belonging to the technical field of diagnosis detection devices. Background Art

[0002] Chronic obstructive pulmonary disease (COPD) in the elderly is the most prevalent respiratory disease worldwide. It is characterized by persistent airflow limitation and often presents with symptoms of cough, sputum production, and dyspnea. Effective coughing helps COPD patients to expel sputum smoothly, maintain airway patency, and prevent complications such as atelectasis. However, COPD patients are mainly elderly people. Regarding effective coughing, they face learning difficulties, are unable to objectively judge the effectiveness of coughing, and are prone to forgetting over time.

[0003] At present, there are schemes for detecting coughs by means of audio signals, sound sensors, vibration signals, acceleration sensors and pressure sensors. For example, patent CN117316192A discloses a cough monitoring method and related equipment, which detects and analyzes the cough status by collecting vibration signals and audio signals. These monitoring devices are mostly used for continuous monitoring of coughs in patients with respiratory diseases such as asthma. The structure is relatively complex and requires a large amount of data analysis algorithm support. The equipment cost is high, and the degree of specialization required for operating the equipment is high. Medical personnel are required to interpret the monitoring results, so it is not suitable for daily home detection. However, for COPD patients, daily exercises for effective coughing are very important for the control of the disease, but there is currently no auxiliary detection equipment for daily exercises for effective coughing, and patients cannot objectively judge whether the coughing action is effective. Utility Model Content

[0004] In order to assist patients in performing daily exercises of effective coughing and at the same time meet the requirements of low cost and easy operation, the utility model provides an effective cough detection device, and the technical solution is as follows.

[0015] Advantages of the utility model:

[0016] The effective cough detection device of the utility model obtains cough airflow through a mask and a sealed tube, and innovatively presents the size of the cough airflow objectively by rolling a movable ball on an inclined plane, so that the cough intensity and whether the cough is effective can be intuitively judged. It is not only objective but also easy to operate, and is an "aging-friendly" cough detection device. At the same time, a display screen is used to display whether the cough is effective, which is convenient for patients to perceive their own coughing status.

DETAILED DESCRIPTION

[0019] The following is a specific description of the utility model.

[0020] Example 1

[0021] like Figure 1 As shown, an effective cough detection device provided by the utility model includes: a mask 1, a sealing tube 2, a horizontal tilt sensor 3, a movable ball 4, an infrared sensor 5, an ultrasonic distance sensor 6, a development board 7, and a display 8;

[0022] The sealing tube 2, the horizontal tilt sensor 3, the movable ball 4, the infrared sensor 5, and the ultrasonic distance sensor 6 are arranged in a receiving chamber, and the receiving chamber includes an inclined plane, and the bottom of the inclined plane is provided with a starting position of the movable ball 4, and the bottom of the starting position is a horizontal plane; the infrared sensor 5 is arranged just above the starting position; the ultrasonic distance sensor 6 is arranged at the top of the inclined plane, and the distance measuring direction is parallel to the inclined plane;

[0023] One end of the sealing tube 2 is connected to the mask 1, and the other end is connected to the accommodating cavity through the starting position of the movable ball 4;

[0024] The development board 7 is electrically connected to the horizontal tilt sensor 3, the infrared sensor 5, the ultrasonic distance sensor 6, and the display 8 respectively. The development board of this embodiment can adopt STM32F407ZGT6, STM32F103C8T6, etc., which is used for conventional information collection and data transmission, including receiving data from the horizontal tilt sensor 3, the infrared sensor 5 and the ultrasonic distance sensor 6 and transmitting them to the display for display.

[0025] The working principle of this embodiment:

[0026] Before use, the tester places the device horizontally. At this time, the active ball should be in the starting position, and the bottom of the starting position must be kept horizontal. The horizontal tilt sensor determines whether the effective cough detection device is in the horizontal plane by detecting the deviation of the ball on the plane. If the instrument is in the horizontal plane, the display connected to the development board will display "Levelness Pass", otherwise it will display "Levelness Failure"; at the same time, the infrared sensor directly above the starting position detects whether the active ball is in the starting position. If the active ball is in the starting position, the display connected to the development board will display "Returned", otherwise it will display "Not Returned". When both of the above conditions are met, you can proceed to the next step.

[0027] The tester wears a mask and coughs. The moving ball rolls upward along the slope under the action of the coughing airflow. At this time, the ultrasonic distance sensor detects and records the closest distance between the moving ball and the ultrasonic distance sensor, and then transmits the distance data to the development board, which transmits the distance to the display for display.

[0028] Among them, the smaller the closest distance between the moving ball and the ultrasonic distance sensor, the more effective the cough is. The distance threshold for distinguishing whether the cough is effective can be set according to the experience of the tester or doctor, or it can be determined with the assistance of the hospital's testing equipment, and can be adjusted later depending on the actual situation of the tester.

[0029] For example, if the length of the inclined plane is 20cm, when the patient uses the detection device for the first time, after a series of coughing movements, the doctor can evaluate whether the cough is effective, or the hospital's special medical equipment can assist in evaluating whether the cough is effective, thereby determining the critical value of whether the cough is qualified, that is, the threshold of the closest distance mentioned above, such as 10cm. After recording the threshold, the patient can judge the effectiveness of the cough at any time in daily life.

[0030] Furthermore, the determined threshold value can also be pre-stored in the development board. After that, when the patient performs cough detection again, the development board receives the closest distance collected by the ultrasonic distance sensor, performs a logical judgment on the size of the threshold value, and displays "qualified" or "unqualified" on the display. For example, if the distance collected by the ultrasonic distance sensor is less than or equal to 10cm, the cough is judged to be "qualified", otherwise it is judged to be "unqualified" and displayed on the display.

[0031] Furthermore, two operable buttons may be provided on the display 8 for inputting the age and gender of the testee.

[0032] As the number of users of cough detection devices increases, a large amount of experience data will be generated, which can be fully utilized (for example, the threshold value average of patients of the same age group and gender can be taken). At the same time, in order to improve the detection efficiency, these experience data can be written into the development board in advance, and the threshold value can be associated with the patient's age and gender and stored.

[0033] The development board obtains the age and gender information input by the operable button, and selects the corresponding threshold for judgment. This operation can be completed by the patient himself without the assistance of doctors or hospital equipment, saving medical resources, thus saving manpower and material costs and improving detection efficiency.

[0034] The distance threshold is written into the development board in advance through a data table. The format of the data table is shown in Table 1 below. When the development board obtains the age and gender information of the detector, it can automatically read the corresponding distance threshold for judgment.

[0036]

[0037] The effective cough detection device of this embodiment objectively and intuitively reflects the size of the cough airflow through the moving distance of the ball on the inclined plane, thereby judging whether the cough is effective; the device has a simple and portable structure, low manufacturing cost, and simple usage, and the elderly can operate it easily; a display is provided to obtain objective cough data at any time, which effectively assists the detection and training of effective coughing of elderly patients.

[0038] Furthermore, the distance threshold can be selected according to the age and gender of the tester, and effective empirical data can be fully utilized to improve the detection efficiency, save medical resources, and reduce the manpower and material costs of the detection.

[0039] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
