Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary equipment, and in particular relates to a back-knocking sputum-discharging device. Background Art

[0002] Most respiratory diseases will lead to increased airway secretions. If they are not discharged in time, they may cause airway obstruction and lead to poor respiratory tract system. Once an infection occurs, it will not only affect the normal functioning of the respiratory system, but may also further worsen the condition. The premise for timely removal of airway secretions is that the user has the ability to cough and the secretions are fluid. If the secretions are not fluid, cannot stimulate the airway mucosa to cause a cough reflex, or the user does not have the ability to cough autonomously, the airway secretions cannot be cleared. Back tapping is a common auxiliary expectoration method. It vibrates the patient's back with the palm of your hand or mechanical tapping, so that the sputum attached to the alveoli or bronchial wall loosens and falls off, making it easier to cough out.

[0003] At present, the clinical method of tapping the back to expectorate is generally that the nursing staff taps the patient's back with a certain frequency and strength by hand or a handheld tapping head to promote the smooth discharge of sputum in the patient's body. This method will affect the expectoration effect due to the different strength of the operator's hands, and the operator is prone to fatigue, increasing the work intensity and workload of the nursing staff. In order to solve this technical problem, Chinese Patent Publication No. CN218923182U discloses a reciprocating back tapping expectoration device. When in use, the user sits on a cushion with his back against the back-shaped board, and then uses a remote control to control the device to perform multi-point back tapping. The operation is simple, but this patent has no fixing device, and the user needs to adjust the sitting position by himself and lean against the back-shaped board to achieve the effect of tapping expectoration. The tapping effect is easily affected by the improper body position of the user during use. Chinese patent publication number CN114522392A discloses an exhalation visualization pressure training device for assisting users in coughing and expectorating. The main body is a wearable outer garment, and is equipped with a driving device for monitoring short-time exhalation volume. When the user's short-time breathing volume reaches the standard, the driving device is started, and the airbag is used to pressurize the abdomen, thereby promoting the user to cough and expectorate. However, this patent uses external force to pressurize the user's abdomen, which may easily cause discomfort to the user, and the back tapping point is single, which cannot loosen the sputum.

[0004] In addition, most of the auxiliary expectoration instruments on the market are equipped with large external devices such as air pumps, which are complex, have few applicable scenarios, and are expensive. At the same time, the existing auxiliary expectoration instruments do not have devices that are combined with effective expectoration training, nor do they include intelligent feedback and monitoring mechanisms, which cannot reflect the effectiveness of expectoration training and ensure the safety of the training process.

[0032] like Figure 1-Figure 5As shown, this embodiment provides a back-tapping sputum removal device, including a wearable garment 1, on which a tapping mechanism 2, an abdominal pressure monitoring mechanism 3 and a body position monitoring mechanism 4 are provided. The tapping mechanism 2 is arranged on the back of the wearable garment 1 and is distributed according to the shape of the human lung lobe; the abdominal pressure monitoring mechanism 3 is arranged on the front of the wearable garment 1 and is used to monitor the abdominal pressure of the human body; the body position monitoring mechanism 4 is used to monitor the forward leaning angle of the human body and control the switch of the abdominal pressure monitoring mechanism 3. The abdominal pressure monitoring mechanism 3 can assist the user in determining whether the body position is correct when coughing. When the user maintains a suitable body position, the abdominal pressure monitoring mechanism 3 is turned on to monitor the pressure change of the user's abdomen and determine the user's use status. When the user's body position changes, such as leaning forward or backward, the abdominal pressure monitoring mechanism 3 is turned off and cannot monitor the pressure of the user's abdomen. In addition, the change of the abdominal pressure monitoring mechanism 3 can facilitate the user to distinguish between coughing and breathing to determine the user's use status.

[0033] The utility model utilizes the percussion mechanism 2 to tap the user's back, generating regular periodic vibrations on the lung lobe of the human body, which can loosen the sputum in the user's respiratory tract and gather it in the trachea, making it easier to cough out. The body position monitoring mechanism 4 can monitor the forward leaning angle of the human body and control the switch of the abdominal pressure monitoring mechanism 3, so that the user can maintain a suitable body position for expectoration. The utility model can save manpower, improve the accuracy of percussion expectoration, and at the same time assist with effective expectoration training and health education, reduce the threshold for expectoration operation, and assist patients in self-expelation management.

[0034] like Figure 1 As shown, in this embodiment, the wearable clothing 1 includes a vest outer layer 101, a rubber inner layer 102 is provided on the inner side of the vest outer layer 101, a tapping mechanism 2 is arranged between the vest outer layer 101 and the rubber inner layer 102, a tightening belt 103 is provided on the vest outer layer 101, and the abdominal pressure monitoring mechanism 3 and the body position monitoring mechanism 4 are both arranged on the tightening belt 103; the vest outer layer 101 is made of honeycomb mesh. The tightening belt 103 can be an elastic belt, and its connection method is a buckle or Velcro connection. The tightening belt 103 is an elastic belt that wraps the whole abdomen. The abdominal pressure monitoring mechanism 3 is located on the tightening belt 103, and can sense the abdominal pressure by closely fitting with the skin. When the user breathes abdominally, the abdominal pressure increases, the abdominal circumference increases, and the value of the abdominal pressure monitoring mechanism 3 increases accordingly.

[0035] Specifically, the tapping mechanism 2 includes a plurality of tapping heads, and the plurality of tapping heads are distributed according to the shape of the human lung lobes; the tapping heads include a tapping outer cylinder 201 and a tapping fixed seat 202, the tapping outer cylinder 201 is slidably mounted on the tapping fixed seat 202, and an elastic recovery member is provided between the tapping outer cylinder 201 and the tapping fixed seat 202; a driving motor is provided inside the tapping fixed seat 202, and a ratchet assembly is provided between the driving motor and the tapping outer cylinder 201, and the driving motor is used to drive the ratchet assembly to move, so that the tapping outer cylinder 201 slides along the tapping fixed seat 202 under the action of the elastic recovery member, thereby tapping the human body.

[0036] The utility model arranges 10 tapping heads on the back of the wearable garment 1 according to the distribution of the lung lobes, and taps are performed in sequence from outside to inside and from bottom to top on each side. All tapping heads can also be activated at the same time, which generates regular periodic vibrations, taps the user's back from outside to inside and from bottom to top, loosens the phlegm in the user's respiratory tract and gathers it in the trachea, making it easier to cough it out. The product can set the tapping frequency, strength and number of times to provide a variety of tapping modes to meet user needs.

[0037] like Figure 2-Figure 4 As shown, the ratchet assembly includes a first end ratchet 203 and a second end ratchet 204 that match each other, the first end ratchet 203 is arranged on the inner side of the knocking outer cylinder 201, and the second end ratchet 204 is connected to the driving motor. The driving motor includes an inner stator 205 and an outer rotor 206, the inner stator 205 is arranged on the knocking fixed seat 202, and a mounting groove adapted to the elastic return member is provided in the middle of the inner stator 205, and the outer rotor 206 is arranged on the outer side of the inner stator 205, and the outer rotor 206 is connected to the second end ratchet 204. The elastic return member includes a return spring 207, and the two ends of the return spring 207 are respectively connected to the knocking outer cylinder 201 and the knocking fixed seat 202.

[0038] Driven by the driving motor, the knocking outer cylinder 201 does not rotate with the outer rotor 206. At this time, the force generated by the first end face ratchet 203 and the second end face ratchet 204 lifts the knocking outer cylinder 201. When the outer rotor 206 rotates through an angle of 45°, the knocking outer cylinder 201 reaches its maximum rising height, and then quickly resets under the traction of the return spring 207. This rapid action process generates an impact force, thereby achieving the knocking effect. Since the knocking fixed seat 202 is connected to the rubber inner layer 102, and the knocking outer cylinder 201 is connected to the vest outer layer 101, the rubber inner layer 102 needs to be designed with a certain pre-tightening force to ensure that it is close to the body, and the vest outer layer 101 remains relatively loose to ensure that the knocking outer cylinder 201 is lifted up instead of pushing the inner stator 205 back when the device is working, so that the device can effectively realize the knocking function while ensuring the comfort of use. In addition, in specific applications, the shape and tapping force of the tapping outer cylinder 201 can be continuously optimized based on practical feedback, further improving the tapping effect of the tapping mechanism 2 and providing users with a more comfortable and convenient use experience.

[0039] like Figure 5 As shown, in this embodiment, the body position monitoring mechanism 4 includes a rotating paddle 401 and an arc-shaped slide 402. One end of the rotating paddle 401 can slide along the arc-shaped slide 402 by gravity when the human body leans forward. The two ends of the arc-shaped slide 402 are respectively provided with an upper limit block 411 and a lower limit block 412 to limit the rotating paddle 401. The arc-shaped slide 402 is provided with a working point and a reminder point. The working point is electrically connected to the abdominal pressure monitoring mechanism 3, and the reminder point is connected to a reminder circuit. When the human body leans forward, the rotating paddle 401 contacts the working point, and the abdominal pressure monitoring mechanism 3 is powered on and monitors the abdominal pressure of the human body; the rotating paddle 401 contacts the reminder point, and the reminder circuit is powered on and issues a reminder. The body position monitoring mechanism 4 also includes a power supply 403, the positive pole of the power supply 403 is electrically connected to the rotating paddle 401, and the reminder circuit is electrically connected to the negative pole of the power supply 403.

[0040] The abdominal pressure monitoring mechanism 3 includes a pressure sensor 301, which is arranged at the front of the wearable garment 1. The pressure sensor 301 is connected to a relay 404, one end of the control coil of the relay 404 is electrically connected to the working point, and the other end of the control coil of the relay 404 is electrically connected to the negative pole of the power supply 403. The pressure sensor 301 is connected to a control mainboard, and a wireless communication module 5 is arranged on the control mainboard. Since electronic components such as the control mainboard, the pressure sensor 301 and the wireless communication module 5 are existing mature technologies, they are not described in detail.

[0041] The reminder point includes a large-angle reminder point and a small-angle reminder point, and the large-angle reminder point and the small-angle reminder point are arranged on both sides of the working point; the reminder circuit includes a large-angle reminder circuit and a small-angle reminder circuit, and the large-angle reminder circuit is electrically connected to the large-angle reminder point, and the small-angle reminder circuit is electrically connected to the small-angle reminder point. The large-angle reminder circuit includes a first voice player 405 and a first prompt light 406, and the first voice player 405 and the first prompt light 406 are connected in series between the large-angle reminder point and the negative pole of the power supply 403. The small-angle reminder circuit includes a second voice player 407 and a second prompt light 408, and the second voice player 407 and the second prompt light 408 are connected in series between the small-angle reminder point and the negative pole of the power supply 403. The working point is connected with a working circuit, and the working circuit includes a third voice player 409 and a third prompt light 410, and the third voice player 409 and the third prompt light 410 are connected in series between the working point and the negative pole of the power supply 403.

[0042] The first prompt light 406, the second prompt light 408 and the third prompt light 410 are all colored lights. When the user leans forward, the rotating paddle 401 swings in the counterclockwise direction. The tilt angle is different, and the swing angle also changes accordingly, connecting the corresponding circuit. When the user's tilt angle is insufficient, the second voice player 407 and the second prompt light 408 are powered on, the second voice player 407 prompts the user "please lean forward slightly", and the second prompt light 408 lights up yellow; when the user's tilt angle is too large, the first voice player 405 and the first prompt light 406, the first voice player 405 prompts the user "please move back a little", and the first prompt light 406 lights up red; when the user's tilt angle is appropriate, the third voice player 409 and the third prompt light 410 are powered on, the third voice player 409 prompts the user "please take 5 slow, deep breaths", the third prompt light 410 lights up green, and the abdominal pressure monitoring mechanism 3 is started at the same time. When the abdominal pressure of the human body changes, the electronic sensitive element is deformed, and the conversion element plays a role, causing the circuit current to change. At this time, the measuring circuit senses the change, converts it into visual data and records it, and transmits the data to the connected device using the wireless communication module 5. The wireless communication module 5 can be connected to the user's mobile phone via Bluetooth, so that the user can summarize the data and realize the user's self-management of sputum training.

[0043] The product of the utility model has a voice prompt function, which can provide voice guidance for the user's training, remind the user of the precautions and benefits of effective sputum coughing training, and promote the user to persist in the training. When helping the user to perform effective sputum coughing training, it plays the role of education, replacing repeated manual education.

[0044] The abdominal pressure monitoring mechanism 3 of this product includes a pressure sensor 301. When the user coughs up phlegm, the value of the pressure sensor 301 changes quickly, indicating that the user's diaphragm movement increases. At this time, coughing and breathing can be distinguished by the value change rate of the pressure sensor 301 to determine the user's usage status. After the tapping mechanism 2 stops tapping, there will be a voice prompt "Please lean forward". There is a body position monitoring mechanism 4 on the tightening belt 103. Through the circuit device, the user's body position can be monitored in real time and voice feedback can be given to guide the user to sit forward before coughing training. The body position monitoring mechanism 4 is located in the product tightening belt 103. When the user leans forward, the rotating paddle 401 swings in a counterclockwise direction. The forward tilt angle is different, and the swing angle also changes accordingly. The corresponding circuit is connected, and the prompt lights of different colors and the corresponding voice are started. After the body position monitoring is qualified, it prompts "Please take 5 deep breaths", "Inhale", and "Exhale". At this time, the pressure sensor 301 will change its value with the inhalation and exhalation action, which is convenient for reading the results. After that, the voice prompts "Please cough quickly and hard" and "Cough up phlegm". The user can follow the voice prompts for effective coughing training.

[0045] The main body of this product is a vest-style back-tapping expectoration device. This product mainly realizes the following three functions: auxiliary expectoration, health education and intelligent feedback, so as to overcome the disadvantages of existing products such as troublesome use, inconvenient to carry, few applicable scenes, high cost, and inability to reflect the effectiveness of expectoration training. In this product, the wearable clothing 1 can be set in different sizes according to different body shapes. The wearable clothing 1 has a tightening belt 103 and a shoulder strap, which are both adjustable for accurate positioning of tapping to serve more users.
