Description

Technical Field

[0001] This invention relates to the field of sputum suction machine technology, specifically a working control method for a sputum suction machine and the sputum suction machine itself. Background Technology

[0002] Patients with respiratory diseases often experience respiratory secretion retention during the recovery process, requiring external mechanical vibration to assist in expectoration and promote airway patency. Such devices are widely used in hospital respiratory departments and home care settings, using periodic vibrations to loosen sputum from the chest cavity.

[0003] Existing vibration sputum clearance devices mainly include handheld percussion sputum clearance machines and wearable inflatable sputum clearance vests. Among them, handheld devices require medical staff to hold the percussion head for a long time to repeatedly pat the patient, which not only greatly increases the labor intensity of medical staff, but also easily leads to unstable percussion force and frequency due to arm fatigue during long-term operation, affecting the treatment effect.

[0004] While wearable sputum clearance vests can achieve automatic vibration sputum clearance through repeated inflation and deflation of air bladders, they still have obvious structural defects in practical applications. Existing sputum clearance vests usually use a structure where the air bladder is directly attached or separated by a single layer of fabric. Because the surface tension of the air bladder is large and its texture is relatively hard after inflation, it lacks an effective flexible buffering medium. As a result, the hard air bladder directly compresses the patient's chest skin when vibrating at high frequency, which can easily cause skin redness, swelling, pain, or even soft tissue contusions. This rigid contact can cause great physical discomfort and psychological fear, especially for infants with delicate skin or elderly patients with reduced sensory abilities.

[0005] In addition, the surface of the human chest is an irregular arc shape, and existing sputum clearance vests cannot adapt to the specific body shape of patients. Gaps are easily generated between the air bladder and the chest wall, causing the vibration energy to be severely attenuated and lost in the air gap. This makes it impossible to accurately and efficiently transmit the energy to the deep lung tissue, thereby greatly reducing the efficiency of sputum liquefaction and prolonging the treatment cycle for patients. Summary of the Invention

[0006] The purpose of this invention is to provide a working control method for a sputum suction machine and a sputum suction machine in order to solve the problems mentioned above.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a working control method for a sputum suction machine and a sputum suction machine, comprising: a sputum suction main unit and a vibrating vest, wherein the sputum suction main unit is connected to the vibrating vest via a pumping pipe, the vibrating vest comprises a vest body and an air inlet bag disposed on its outer side, the vest body comprising, from the outside to the inside, a woven outer layer, a middle layer and an inner layer, an air bladder is disposed between the woven outer layer and the middle layer, a silicone block is disposed between the middle layer and the inner layer, a pressure sensor is disposed on the inner layer, the air bladder is connected to the air inlet bag via a branch air pipe, and the pumping pipe is inserted into the air inlet bag to supply air to the air bladder.

[0008] Preferably, the vest body is further fixedly connected with shoulder straps and binding straps for wearing and securing, the shoulder straps being located on both sides of the upper part of the vest body, and the binding straps being located on both sides of the lower part of the vest body.

[0009] Preferably, the air intake is fixedly connected to the surface of the woven outer layer facing away from the middle layer, and the air intake has an internal receiving chamber for the end of the pump pipe to be inserted and sealed.

[0010] Preferably, the airbag has a flat structure and is horizontally disposed in the gap between the woven outer layer and the middle layer, and the sidewall of the airbag is connected to the branch air tube.

[0011] Preferably, one end of the branch trachea is connected to the airbag, and the other end extends through the woven outer layer to the outside and is connected to the inside of the air intake bag.

[0012] Preferably, the silicone block is embedded in the gap between the middle layer and the inner layer, and the position of the silicone block corresponds to the vertical projection position of the airbag.

[0013] Preferably, the pressure sensor is attached and fixed to the inner layer on the side of the surface facing the patient's skin, and the number of pressure sensors is five, which are respectively distributed in the upper and lower regions of the two lungs and the middle region of the chest.

[0014] Preferably, the number of airbags is five, and they are distributed respectively in the upper and lower regions of the two lungs and the middle region of the chest. The airbags, silicone blocks and pressure sensors are arranged in a one-to-one correspondence in the vertical direction.

[0015] Preferably, the outer woven layer is made of a breathable mesh fabric material, the middle layer is made of an elastic knitted fabric, and the inner layer is made of a skin-friendly cotton material.

[0016] Preferably, a working control method for a sputum suction machine, applied to any of the above-mentioned sputum suction machines, includes an initialization and wearing detection step, starting the sputum suction host and collecting the contact pressure signal of the inner side of the vest body in real time through pressure sensors, and determining that the vibrating vest has been correctly worn when the pressure values ​​of the five pressure sensors all exceed the preset threshold, and the system enters the standby preparation state. The next step involves airbag inflation and adaptive fitting. The sputum suction unit controls the air pump to deliver gas to the air inlet bag through the pump tube. The gas is then inflated into the airbag between the outer and middle layers of the braided fabric through the branch tube. The airbag expands and pushes the middle layer and silicone block towards the body until the pressure values ​​of each area fed back by the pressure sensor reach the preset treatment fitting pressure range. Then the unit stops inflation and maintains a constant air pressure. Next, the zonal pulse vibration treatment step is performed. The sputum suction unit outputs pulse airflow signals according to the preset program, causing the airbag to periodically expand and contract. The vibration force is transmitted to the silicone block through the middle layer and uses the flexible buffering properties of the silicone block to convert the high-frequency low-amplitude vibration into deep low-frequency mechanical waves that act on the corresponding lung and chest areas of the patient. Simultaneously, dynamic pressure monitoring and feedback adjustment steps are performed. During the treatment, the pressure sensor continuously monitors the changes in the patient's body surface pressure. If the pressure value in a certain area is lower than the lower limit of safety due to the patient's breathing or changes in body position, the sputum suction host will automatically increase the air supply to the corresponding airbag in that area to compensate for the pressure. If the pressure value is higher than the upper limit of safety, the pressure relief valve will be opened to release a small amount of air to ensure the fit stability and safety during the treatment process. Finally, the treatment ends and the repositioning steps are performed. After the preset treatment time is reached, the sputum suction host stops outputting pulse signals and controls the exhaust component to work, expelling the gas in the airbag through the branch trachea, air inlet bag and pump tube, so that the vest body returns to a relaxed state. Then the system automatically shuts off or enters sleep mode.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention effectively solves the problem of pressure pain caused by direct contact between the airbag and human skin by placing a silicone block as a flexible conductive medium. The high damping characteristics of the silicone block can convert the high-frequency mechanical vibration of the airbag into a gentle deep transmission wave, which significantly improves the loosening effect on sputum in the deep lungs, while protecting the patient's delicate skin tissue.

[0018] This invention utilizes five sets of independent pressure sensors and airbags to sense the fit status of different lung areas in real time and automatically adjust the local air pressure. This ensures that the vibrating vest maintains a constant optimal treatment pressure when the patient's breathing fluctuates or their body position changes slightly, avoiding vibration energy loss due to poor fit or discomfort caused by excessive tightness.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0023] Reference Figures 1 to 6 According to an embodiment of the present invention, a working control method and a sputum suction machine are provided, comprising: a sputum suction host 1 and a vibrating vest 2. The sputum suction host 1 is connected to the vibrating vest 2 via a pumping pipe 3. The vibrating vest 2 includes a vest body 21 and an air inlet bag 22 disposed on its outer side. The vest body 21 includes, from the outside to the inside, a woven outer layer 26, a middle layer 27, and an inner layer 28. An air bladder 29 is disposed between the woven outer layer 26 and the middle layer 27. A silicone block 210 is disposed between the middle layer 27 and the inner layer 28. A pressure sensor 211 is disposed on the inner layer 28. The air bladder 29 is connected to the air inlet bag 22 via a branch air pipe 212. The pumping pipe 3 is inserted into the air inlet bag 22 to supply air to the air bladder 29. Shoulder straps 25 and straps 24 for wearing and securing are also fixedly connected to the vest body 21. The shoulder straps 25 are located on the upper two sides of the vest body 21, and the straps 24 are located on the lower two sides of the vest body 21. The air inlet bag 22 is fixedly connected to the woven outer layer 26. Layer 26 faces away from the middle layer 27. The air intake bag 22 has a cavity inside for the insertion and sealing of the end of the air pump tube 3. The air bag 29 has a flat structure and is horizontally positioned in the gap between the woven outer layer 26 and the middle layer 27. The side wall of the air bag 29 is connected to a branch air tube 212. One end of the branch air tube 212 is connected to the air bag 29, and the other end extends through the woven outer layer 26 to the outside and connects to the inside of the air intake bag 22. The silicone block 210 is embedded in the gap between the middle layer 27 and the inner layer 28. The position of the silicone block 210 corresponds to the vertical projection position of the air bag 29. The pressure sensor 211 is attached and fixed to the inner layer 28 facing the patient's skin. There are five pressure sensors 211, which are distributed in the upper and lower regions of the two lungs and the middle region of the chest, respectively. There are five air bags 29, which are distributed in the upper and lower regions of the two lungs and the middle region of the chest, respectively.

[0024] In a hospital clinical nursing environment, medical staff first assist the patient to assume a sitting or semi-recumbent position, place the vibration vest 2 on the patient's torso, and adjust the length of the shoulder straps 25 and binding straps 24 to fit the patient's body shape, ensuring that the vest body 21 fits tightly against the chest. Then, the air delivery end of the pump tube 3 is aligned with the interface of the air inlet bag 22 and pushed in forcefully until it is locked and sealed. After starting the sputum suction host 1, the internal control module of the host drives the air pump to work according to the preset program. High-pressure gas enters the air inlet bag 22 through the pump tube 3 and is diverted to five independent air bags 29 through the branch air tubes 212. After the air bags 29 are inflated, they compress the middle layer 27, thereby pushing the silicone block. 210 displaces towards the inner layer 28. Due to the excellent flexibility and resilience of the silicone block 210, it can transform the rigid extrusion force generated by the airbag 29 into a gentle deep vibration wave, effectively avoiding the discomfort caused by the hard airbag directly contacting the skin. At the same time, the five pressure sensors 211 on the inner layer 28 monitor the contact pressure of each area in real time. When insufficient pressure is detected in a certain area, the main unit automatically adjusts the flow rate of the corresponding airway to ensure that the vibration energy evenly covers the upper and lower lobes of both lungs and the parasternal area. After the treatment, the main unit automatically vents air, the airbag 29 contracts and resets, and medical staff can remove the device by untying the straps 24 and shoulder straps 25.

[0025] In a home-based rehabilitation environment, patients or their families can operate independently. Before use, check the connection between the pump tube 3 and the air inlet bag 22 to ensure there is no air leakage. Then, put on the vibration vest 2 properly and select the low-frequency soothing mode suitable for home use using the buttons on the panel of the sputum expectoration host 1. At this time, the airflow pulse frequency output by the host is low, and the air bag 29 circulates air at a slow rhythm. The silicone block 210 massages the chest tissue with vibration during repeated compression and rebound. This structure is particularly suitable for the elderly, the weak, or people who are sensitive to vibration. It can effectively promote the loosening and drainage of respiratory secretions. During use, if the vest shifts slightly due to the patient's breathing fluctuations, the pressure sensor 211 will immediately capture the pressure change signal and feed it back to the host. The host will then fine-tune the air supply pressure to maintain the best treatment state without frequent manual intervention. After use, turn off the power and store the device in a dry place. The straps 24 and shoulder straps 25 are adjustable to facilitate size adaptation when used by different family members.

[0026] The working principle of this invention is as follows: After the sputum suction host 1 is started, gas is delivered to the air intake bag 22 of the vibrating vest 2 through the air pump pipe 3. The gas enters the air bag 29 between the outer woven layer 26 and the middle layer 27 through the branch trachea 212, causing it to inflate. The air bag 29 pushes the middle layer 27 and the silicone block 210 to fit tightly against the patient's chest. The pressure sensor 211 on the inner layer 28 monitors the pressure in each area in real time and feeds it back to the host to maintain a constant fit. The host outputs pulsed airflow according to the preset program to make the air bag 29 vibrate periodically. The vibration force is buffered by the silicone block 210 and converted into deep mechanical waves that act on the lungs. After the treatment, the host controls the exhaust to make the air bag 29 contract and reset. The whole process realizes the automated closed-loop control from air source drive to flexible vibration transmission and intelligent pressure feedback.

[0027] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
