Description

Technical Field

[0001] The invention relates to the technical field of oscillating expectoration devices, and in particular to a multi-mode chest wall oscillating expectoration device. Background Art

[0002] Cold is a common acute upper respiratory tract viral infection disease, and its symptoms are generally fever, headache, cough, and sputum. However, due to the weak immunity of the elderly, it is difficult to cough up sputum, which can easily get stuck in the throat or trachea and swallowed in the stomach, which is not conducive to the discharge of sputum.

[0003] Generally, the most commonly used method in clinical practice is manual back tapping to expectorate, but the frequency and strength of this method are difficult to master, which can easily cause pain to patients and the effect is not significant. The introduction of an extracorporeal vibrating expectoration machine has greatly solved these problems. A vibrating expectoration machine is a machine that uses the principle of mechanical vibration to loosen sputum and facilitate coughing. It can help weak patients enhance their ability to remove secretions such as sputum from the respiratory system, improve stagnant pulmonary blood circulation, prevent and reduce the occurrence of complications of respiratory diseases, greatly shorten the course of treatment, reduce the pain of patients, and has no side effects, becoming a good helper for medical staff in auxiliary treatment. Since the device is usually only used in medical institutions, but patients' demand for the function of expectoration assistance is not limited to hospitalization, the device will be insufficiently portable due to its single use occasion.

[0004] After searching, the Chinese invention patent with publication number CN106109216B discloses a high-frequency chest wall oscillation expectoration device, including a high-frequency chest wall oscillation therapeutic device, an operation control instrument is provided on the high-frequency chest wall oscillation therapeutic device, a host switch is provided on the upper side of the operation control instrument, an alarm indicator light is provided on the right side of the host switch, a frequency intensity control button is provided on the front side of the alarm indicator light, a base output area is provided on the front side of the operation control instrument, an oscillation percussion head base is provided on the base output area, a high-frequency oscillation percussion head base is provided on the right side of the oscillation percussion head base, a therapeutic device placement box is provided on the lower side of the operation control instrument, and an instrument placement slot is provided inside the therapeutic device placement box. This application uses a high-frequency oscillation percussion head to vibrate the patient's chest cavity to achieve the effect of promoting the discharge of sputum, but the use of the high-frequency oscillation percussion head needs to be coordinated with the operation control instrument. The coexistence of the two limits the use occasions, which will lead to a reduction in the convenience of using the device. Summary of the invention

[0031] Example 1

[0032] Refer to the attached Figure 1-5The present application provides a multi-mode chest wall oscillation expectoration device, comprising a vest 1, a plurality of fixing boxes 4 are arranged on the inner side of the vest 1, a driving mechanism, an oscillation mechanism and a vibration mechanism are arranged inside the fixing box 4, and the vest 1 can be worn on the chest wall of the patient when the device is in use, so the fixing box 4 can be used to transmit the oscillation and vibration to the chest wall, thereby acting on the trachea and bronchi of the lungs, thereby achieving the effect of promoting the discharge of sputum, and the oscillation mechanism and the vibration mechanism are used to promote the discharge of sputum;

[0033] The oscillation mechanism includes a turntable 22, and a plurality of pendulum rods 23 are equidistantly fixedly connected to the outer side of the turntable 22. The pendulum rods 23 are used to beat the patient's chest wall. The rotation of the turntable 22 can make the pendulum rods 23 rotate, so the pendulum rods 23 can continuously hit the patient's chest wall. Therefore, it is only necessary to control the turntable 22 to rotate at a constant speed, so that the pendulum rods 23 can beat at a constant speed and continuously, thereby creating regular oscillations at the patient's chest wall. The vibration mechanism includes a first base 16 and a second base 17. The second base 17 is fixedly connected to springs 15 on both sides, and the second base 17 is fixedly connected to the fixed box 4 through the springs 15. The second base 17 causes shaking by pulling the first base 16, and the fixed box 4 generates vibrations through the shaking of the first base 16. When the second base 17 moves, The first base 16 can be pulled by the attraction between the opposite poles of the magnet blocks 18, that is, when the second base 17 approaches the first base 16, it will pull it, and when the second base 17 is away from the first base 16, the spring 15 can pull the first base 16 to restore its original state. Since the gravity of the first base 16 and the magnet block 18 inside it will make the inertia generated in the movement process, the first base 16 can shake under the action of the spring 15, thereby causing the fixed box 4 to produce irregular vibrations. The driving mechanism is used to drive the rotation of the turntable 22 and the reciprocating movement of the second base 17. The oscillation generated by the rocker arm 23 and the vibration generated by the first base 16 are used to act on the patient's chest wall together, so as to achieve the effect of promoting the discharge of sputum.

[0034] Preferably, a plurality of pockets 3 are fixedly connected to the inner wall of the vest 1 at equal intervals, a strap 301 is fixedly connected to one side of the top of the pocket 3, a connecting buckle is provided between one end of the strap 301 and the other side of the top of the pocket 3, the number of fixing boxes 4 is the same as the number of pockets 3 and corresponds one to one, and the fixing boxes 4 are located inside the pocket 3, the pocket 3 is used to hold the fixing boxes 4, and the fixing boxes 4 can be fixed by using the strap 301 after being held, a rubber pad is provided on the outside of the pocket 3, so that it can contact the patient instead of the pocket 3, thereby ensuring the comfort of the patient when using the device.

[0035] Preferably, a motor 11 is fixedly connected to one side of the inner wall at the bottom end of the fixed box 4, and the driving mechanism includes a reciprocating screw 13, which is fixedly connected to the top end of the output shaft of the motor 11, and the external thread of the reciprocating screw 13 is connected to a nut 19. By rotating the reciprocating screw 13, the nut 19 can reciprocate in the vertical direction. A sliding groove is provided on the rear side of the nut 19, and a guide rail 14 is fixedly connected to the inner wall of one side of the fixed box 4. The nut 19 is slidably connected to the guide rail 14 at the sliding groove. The guide rail 14 can provide a guiding effect for the movement of the nut 19 through the sliding groove, that is, the guide rail 14 can limit the rotation of the nut 19 so that it can only move in a straight line along the guide rail 14.

[0036] Preferably, both sides of the nut 19 are rotatably connected to a rotating shaft 20, and a turntable 22 is fixedly connected to one end of the rotating shaft 20. The outside of the rod bodies of the two rotating shafts 20 are connected to gears 21 through keys. One side inner wall of the fixed box 4 is fixedly connected to a rack 12 at both sides of the guide rail 14, and the rack 12 is meshed with the gear 21. Through the meshing of the rack 12 and the gear 21, the gear 21 can rotate as the nut 19 moves, and the rotation can drive the turntable 22, thereby causing the swing rod 23 to rotate. Strip openings 401 are provided on both sides of the side walls of the fixed box 4, and the swing rod 23 extends to the outside of the fixed box 4 at the strip opening 401, and the material of the swing rod 23 is silicone. When the swing rod 23 rotates, it can pass through and extend out of the strip opening 401, so its rotation can produce a slapping effect on the patient's chest wall.

[0037] Preferably, the second base 17 is fixedly connected to the front side of the nut 19, the number of the first bases 16 is several, a groove is provided on the side where the second base 17 and the first base 16 are close to each other, and the second base 17 and the first base 16 are respectively fixedly connected with magnet blocks 18 in the grooves, and the magnetic poles of the two magnet blocks 18 in the second base 17 and the first base 16 on the side where they are close to each other are different, and the two magnet blocks 18 with different magnetic poles will attract each other when they are close, so the movement of the second base 17 will produce a pulling effect on the first base 16, thereby causing it to shake.

[0038] Preferably, the bottom end of the vest 1 is fixedly connected with a skirt 10, and the front sides of the vest 1 and the skirt 10 are provided with a putting-on and taking-off opening, the vest 1 is fixedly connected with a zipper 7 at the putting-on and taking-off opening, and the outer side of the skirt 10 is fixedly connected with a drawstring 6, the zipper 7 and the drawstring 6 are respectively used for the unfolding and folding of the vest 1 and the skirt 10, so that the zipper 7 and the drawstring 6 can facilitate the putting-on and taking-off of the vest 1 and the skirt 10, one end of the drawstring 6 is fixedly connected with a fixing ring 8, and the other end of the drawstring 6 is fixedly connected with a Velcro 9, and the Velcro 9 is a self-hooking integrated Velcro. Both sides of the top of the vest 1 are provided with straps 5. The skirt 10 cooperates with the drawstring 6 and the straps 5 to fix the wearing of the vest 1, so as to ensure the wearing stability of the vest 1.

[0039] Preferably, the vest 1 is provided with an interlayer inside, and the vest 1 is fixedly connected with airbags 2 in the interlayer and on the inner wall of the vest 1 between every two adjacent fixing boxes 4. The airbags 2 in the interlayer of the vest 1 will expand the vest 1 when inflated, thereby ensuring that the fixing box 4 is in close contact with the patient's chest wall. After inflation, the airbags 2 on the inner wall of the vest 1 will limit the fixing box 4 to align it with the chest wall skin and accurately apply vibration and oscillation effects to the chest wall.

[0040] Working principle: When using the device, several fixing boxes 4 can be respectively put into each pocket 3, and the straps 301 can be fastened to achieve the stability of the fixing boxes 4. After that, the vest 1 can be worn after unfastening the zipper 7 and the straps 6. When wearing, the straps 5 can be hung on the patient's shoulders, and the vest 1 can be ensured to be outside the patient's chest wall. Then, the zipper 7 can be fastened again, and the straps 6 can be passed through the fixing ring 8 and fixed to itself with Velcro 9, so as to achieve the binding of the skirt 10, thereby ensuring the stability of the vest 1 when worn. After that, the airbags 2 on the vest 1 can be inflated. When the airbags 2 in the interlayer of the vest 1 expand, the fixing boxes 4 can be stacked close to the patient's chest wall, and when the airbags 2 on the inner wall of the vest 1 expand, the fixing boxes 4 can be limited so that all the fixing boxes 4 can face the patient's chest wall.

[0041] After the vest 1 is put on, the motor 11 can be started. The motor 11 drives the reciprocating screw 13 to rotate so that the nut 19 can move up and down. The movement of the nut 19 can drive the second base 17 to move. Since the second base 17 can produce a pulling effect on the first base 16 through the magnetic attraction between the magnet blocks 18, the movement of the second base 17 will first approach and then move away from each first base 16. In this process, the second base 17 can pull each first base 16 one by one through the magnet block 18, so that the first base 16 can shake under the elastic force of the spring 15, thereby causing the fixing box 4 to produce irregular vibrations;

[0042] At the same time, the movement of the nut 19 can also drive the gear 21 to move on the surface of the rack 12, and the meshing of the two can make the gear 21 rotate. The gear 21 drives the turntable 22 to rotate through the rotating shaft 20, and the turntable 22 drives the swing rod 23 to rotate and extend out at the strip opening 401. Since the fixed box 4 and the pocket 3 are in close contact with the patient's chest wall, the swing rod 23 can continuously and uniformly beat the patient's chest wall, thereby forming a regular oscillation; the oscillation and the above-mentioned vibration are jointly applied to the patient's chest wall, so as to achieve the effect of promoting the discharge of sputum.

[0043] Example 2

[0044] Refer to the attached Figure 6The present application provides a multi-mode chest wall oscillation expectoration device. Compared with Example 1, in order to ensure the accuracy of the wearing position of the device, a plurality of air cushions 24 are fixedly connected to the inner side of the shoulder strap 5 at equal intervals. The air cushions 24 can replace the shoulder strap 5 to contact the patient's shoulders, thereby improving the comfort of the patient when using the device. One end of the shoulder strap 5 is fixedly connected to the top of the rear side of the vest 1, and both ends of the front side of the vest 1 are fixedly connected to a fixing frame 25. A threaded through hole is opened on one side of the fixing frame 25, and the fixing frame 25 is fixedly connected to the threaded through hole. A bolt 26 is threadedly connected at the shoulder strap 5, and the other end of the shoulder strap 5 passes through the fixed frame 25, and a plurality of circular openings are opened on the belt body of the shoulder strap 5. The shoulder strap 5 is fixedly connected with a connecting ring 501 at the circular opening, and the connecting ring 501 is adapted to the bolt 26. When the bolt 26 is loosened, its extension distance in the fixed frame 25 can be controlled. Therefore, when the bolt 26 extends into the fixed frame 25 and can just pass through the connecting ring 501 on the shoulder strap 5, the bolt 26 can fix the shoulder strap 5, thereby realizing the regulation of its use length.

[0045] Working principle: When patients of different body shapes wear the device, after passing the shoulder strap 5 through the fixing frame 25, different connecting rings 501 can be selected to align with the bolts 26, so as to adjust the use length of the shoulder strap 5, thereby ensuring that the wearing position of the vest 1 is outside the patient's chest wall.

[0046] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. The protection scope of the present invention should be based on the protection scope of the claims.
