Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of expectoration, in particular to a wearable oscillating pneumatic mechanism for expectoration. Background Art
[0002] Wearable oscillating expectorants are primarily used to help patients more effectively expel sputum from their respiratory tracts. They consist of a main unit, an airbag vest, and an airway tube. The device's working principle is that compressed air generated by the main unit is repeatedly inflated and deflated into the inflatable vest through the airway tube. When the frequency reaches a certain level, the chest cavity under the vest will oscillate. This oscillation, similar to the effect of a mild cough, helps loosen and liquefy mucus and metabolites on the airway surface, making them easier to expel from the body. Wearable oscillating expectoration machines are suitable for patients with various respiratory diseases. When using the wearable oscillating machine, you only need to wear the airbag vest, then use the airway to connect the wearable oscillating vest to the host, and then operate directly on the host to control the pulse host and fan inside the controller to perform pneumatic work, thereby performing high-frequency inflation and deflation of the airbag vest; The docking tubes on the airbag vests of existing wearable oscillating expectoration machines are mostly fixed in position, and the docking tubes are the initial position of inflation of the airbag vests. Therefore, when the airbag vests are inflated, the effect of this position is the best. However, due to the different body sizes of different people, and the sputum mainly exists in the respiratory tract, especially in the trachea, bronchi and alveoli, some people have a better expectoration effect when using the airbag vests because the inflation port of the airbag vests happens to be at the location of the sputum. However, for some people, due to their different body shapes, the inflation port of the airbag vests is not at the location of the sputum, which leads to relatively poor expectoration effect for such people. For this reason, we propose a pneumatic mechanism for wearable oscillating expectoration. Summary of the Invention
[0003] The purpose of the present invention is to provide a wearable pneumatic mechanism for oscillating expectoration to solve the problems raised in the above-mentioned background technology.

[0008] Preferably, a mounting rod is rotatably connected in the mounting cavity, one end of the mounting rod is fixedly docked with the rotating seat, and a gear is fixedly connected to the mounting rod, and the gear and the rack are meshed with each other.
[0009] Preferably, a balancing frame is fixedly connected to a side of the mounting ring away from the limiting frame, and the balancing frame and the limiting frame are symmetrically distributed.
[0010] Preferably, a balancing block is slidably connected in the limiting groove, the balancing block is slidably connected to the balancing frame, and one end of the balancing block close to the balancing frame is fixedly connected to a limiting plate.
[0011] Preferably, a control switch is provided on a side of the host housing close to the docking port, and a plurality of heat dissipation holes are provided on a side of the host housing away from the docking port.
[0012] Preferably, the output end and the input end of the fan are connected to the pulse host and the air inlet respectively, and a controller is fixedly connected to the housing of the host, and a display and buttons are respectively provided on the controller.
[0013] Preferably, a plurality of straps are fixedly connected to one side of the airbag vest, and a plurality of buckles for fixing the straps are fixedly connected to a side of the airbag vest away from the straps, and the number of the straps is the same as the number of the buckles.
[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention can move the position of the docking tube according to the patient's body size during use, so that the docking tube is located at the position of sputum in the patient's body, and then the rotating seat is rotated to make the clamping plate clamped in the clamping groove of the limiting frame, thereby completing the limiting work of the docking tube. At this time, when expectoration is performed, since the docking tube is directly facing the position of the sputum in the patient's body, the airbag vest is inflated and deflated, which has a better effect on the patient's sputum excretion, thereby avoiding the problem of different expectoration effects for patients of different body sizes due to the fixed inflation and deflation positions of the airbag vest in traditional devices. When the rotating seat is rotated and the card plate is clamped in the clamping slot of the limiting frame, the rotating seat drives the mounting rod to rotate. At this time, the mounting rod drives the gear to rotate. The meshing effect of the gear and the rack can drive the transmission frame to move, so that the clamping block is clamped between the limiting teeth at the corresponding position. At this time, the slider can be fixed and limited, avoiding the problem of displacement of the slider and the position deviation of the docking pipe during the use of the airbag vest. When adjusting the position of the docking tube, the present invention cooperates with the balance frame and the balance block to ensure that the docking tube is always parallel to the fixed ring after moving. At this time, it can ensure that the docking tube is facing the patient's body, and avoids the problem that the silicone film is deformed after the docking tube moves, resulting in different forces around the docking tube, causing the docking tube to be in an inclined state. Through this structure, it can be ensured that when the pulse host inflates and deflates the vest, the docking tube is always facing the patient's body, thereby improving the patient's sputum discharge efficiency.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-9 The present invention provides a technical solution: a wearable oscillating pneumatic mechanism for expectoration, comprising a main body shell 1, one side of the main body shell 1 is provided with two docking ports 12, the side of the main body shell 1 close to the docking port 12 is provided with a control switch 13, the side of the main body shell 1 away from the docking port 12 is provided with a plurality of heat dissipation holes 14, a pulse main body 2 is fixedly connected to the main body shell 1, the pulse main body 2 is respectively connected to the two docking ports 12, a fan 21 is fixedly connected to the main body shell 1, the output end and the input end of the fan 21 are respectively connected to the pulse main body 2 and the air inlet 11, the main body shell 1 is fixed It is connected to a controller 22, which is respectively provided with a display and buttons. An airbag vest 3 is provided on one side of the main body shell 1, and a plurality of straps 31 are fixedly connected to one side of the airbag vest 3. A plurality of buckles for fixing the straps 31 are fixedly connected to the side of the airbag vest 3 away from the straps 31. The number of the straps 31 is the same as the buckles. Two fixing rings 4 are fixedly connected to the airbag vest 3, and a silicone film 41 is fixedly connected inside the fixing ring 4. A docking pipe 42 is fixedly connected to the silicone film 41, and a bellows 45 is fixedly connected between the docking pipe 42 and the docking port 12 on the same side thereof.
[0019] Furthermore, when expectorating the patient, the airbag vest 3 is worn on the patient and fixed with the straps 31 and buckles. According to the size of the user, a distance of one fist is reserved between the inner wall of the airbag vest 3 and the patient's body. Then, one end of the bellows 45 is inserted into the docking port 12 on the main housing 1, and the other end of the bellows 45 is docked with the docking pipe 42. Then, the control switch 13 is pressed to start the device. The device is set through the controller 22 according to the age and body shape of the patient. After adjustment, the fan 21 starts to run, and the fan 21 sucks air through the air inlet 11. The air is then pumped out of the airbag vest 3 through the bellows 45, and the air is then pumped out of the airbag vest 3 through the air inlet 11. The fan 21 then draws the air out of the airbag vest 3 through the air inlet 11 and discharges it to the outside of the main housing 1. When the frequency reaches a certain level, the airbag vest 3 begins to vibrate. This high-frequency oscillation simulates the chest wall oscillation caused by coughing, causing the mucus and metabolites on the surface of the expiratory tract mucosa to relax and liquefy, making them smaller and looser and falling off. When the sputum moves from the bronchi to the main trachea, it is discharged from the body by coughing or artificial suction, thus completing the sputum removal work. Furthermore, by tying the external leg airbag to the patient's leg, and then docking the bellows 45 with the leg airbag, the leg airbag is inflated and deflated at a high frequency through the cooperation of the pulse host 2 and the fan 21. During the inflation stage, the leg airbag will exert a certain pressure on the blood vessels in the patient's leg, pushing the blood back from the distal end to the proximal end of the limb. During the deflation stage of the leg airbag, the blood can be fully infused into the blood vessels, thereby improving the problem of poor blood circulation. This periodic inflation and deflation process helps to reduce blood congestion and reduce the risk of thrombosis. For people who are bedridden for a long time, sit for a long time, or have reduced limb activity after surgery, it can reduce the risk of deep vein thrombosis in the lower limbs, promote patient recovery, and improve the versatility of the host part of the device.
[0020] Combined with attachment Figure 4 、 Figure 5 and Figure 6 As shown, the side wall of the fixed ring 4 is provided with a limiting groove 43, and the slider 6 is slidably installed in the limiting groove 43. The docking tube 42 is rotatably connected with the mounting ring 5, and one side of the mounting ring 5 is fixedly connected to the limiting frame 51. The limiting frame 51 is provided with a number of evenly distributed card grooves 52. The side wall of the fixed ring 4 is slidably connected with the slider 6 of "L" shape structure, and the end of the slider 6 away from the fixed ring 4 is slidably connected to the limiting frame 51, and the end of the slider 6 close to the limiting frame 51 is rotatably connected to the rotating seat 62, and both sides of the rotating seat 62 are fixedly connected with the clamping plates 63, and the end of the rotating seat 62 away from the slider 6 is fixedly connected with the knob 64.
[0021] Furthermore, when the airbag vest 3 is put on, the limiting frame 51 is pressed to move the card plate 63 out of the card slot 52, and then the rotating seat 62 is driven to rotate counterclockwise by the knob 64. At this time, the card plate 63 is separated from the limiting frame 51. Then, according to the patient's body size and the approximate location of the sputum in the patient's body, the mounting ring 5 is rotated to rotate the direction of the limiting frame 51 to the direction in which the docking pipe 42 needs to be displaced. After rotating the mounting ring 5, the docking pipe 42 is manually moved, and the good ductility of the silicone film 41 is used to adjust the position of the docking pipe 42. 2, the limit frame 51 is pressed again, and the knob 64 is used to drive the rotating seat 62 to rotate clockwise again, so that the clamping plate 63 is aligned with the corresponding clamping groove 52 of the limit frame 51, and then the limit frame 51 is released. At this time, the limit frame 51 begins to rebound, so that the clamping plate 63 is clamped in the corresponding clamping groove 52. At this time, the connecting pipe 42 can be limited and fixed so that the connecting pipe 42 is always in this position. When sputum is discharged later, air enters the airbag vest 3 from the connecting pipe 42. Since the connecting pipe 42 is located at the position where the sputum is in the patient's body, the efficiency of sputum discharge can be improved.
[0022] Combined with attachment Figure 6 、 Figure 7 and Figure 8 As shown, a number of evenly distributed limiting teeth 44 are fixedly connected to the inner wall of the limiting groove 43, an installation cavity 61 is provided in the slider 6, and a connecting port connected to the installation cavity 61 is provided at one end of the slider 6 close to the limiting groove 43. A transmission frame 7 is slidably connected to one end of the installation cavity 61 close to the fixed ring 4, and a clamping block 71 is fixedly connected to the end of the transmission frame 7 close to the fixed ring 4. The clamping block 71 is meshed with the limiting teeth 44 through the connecting port, and a rack 72 is fixedly connected to the inner top wall of the transmission frame 7. A mounting rod 8 is rotatably connected to the installation cavity 61, and one end of the mounting rod 8 is fixedly docked with the rotating seat 62. A gear 81 is fixedly connected to the installation rod 8, and the gear 81 and the rack 72 are meshed with each other.
[0023] Furthermore, when the rotating seat 62 rotates counterclockwise, it can drive the mounting rod 8 and the gear 81 to rotate synchronously. At this time, the gear 81 cooperates with the rack 72 to drive the transmission frame 7 to move toward the mounting cavity 61, and the clamping block 71 is retracted into the mounting cavity 61 through the connecting port. At this time, the clamping block 71 is separated from the limiting tooth 44, and the limiting effect of the slider 6 is released. At this time, the mounting ring 5 can be rotated normally, and the limiting frame 51 is used to drive the slider 6 to rotate along the limiting groove 43. When the mounting ring 5 has finished rotating, the rotating seat 62 is rotated clockwise. At this time, the rotating seat 62 will continue to drive the mounting rod 8 and the gear 81 to rotate synchronously clockwise. At this time, the gear 81 cooperates with the rack 72 to drive the transmission frame 7 toward the slider 6. When the locking plate 63 is stuck in the slot 52 of the limiting frame 51, the rotating seat 62 is limited, and the mounting rod 8 is also limited. Due to the mutual engagement between the gear 81 and the rack 72, the transmission frame 7 and the locking block 71 are automatically limited. At this time, the slider 6 can be limited by cooperating with the limiting teeth 44 through the limited block 71. At this time, the mounting ring 5 can be limited by cooperating with the limiting frame 51 to avoid the problem that the position of the connecting pipe 42 is easily offset due to the installation ring 5 not being fixed during the sputum discharge process.
[0024] Combined with attachment Figure 5 As shown, the side of the mounting ring 5 away from the limit frame 51 is fixedly connected to the balance frame 53, and the balance frame 53 and the limit frame 51 are symmetrically distributed. A balance block 9 is slidably connected in the limit groove 43, and the balance block 9 is slidably connected to the balance frame 53. The end of the balance block 9 close to the balance frame 53 is fixedly connected to the limit plate 91.
[0025] Furthermore, during the rotation of the mounting ring 5, the balance frame 53 will rotate synchronously with the mounting ring 5. At this time, the balance frame 53 will drive the balance block 9 to rotate along the limit groove 43 of the fixed ring 4. Since the balance frame 53 and the limit frame 51 are symmetrically distributed, and the balance block 9 cooperates with the limit plate 91, the balance frame 53 can be restricted. At this time, through the cooperation of the balance frame 53 and the limit frame 51, the docking tube 42 can always be in a horizontally aligned state with the fixed ring 4, ensuring that the gas can face the patient's body when entering the airbag vest 3 through the docking tube 42, thereby improving the efficiency of sputum removal.
[0026] Working principle: First, place the main body shell 1 in the designated position, then power on the device, put the airbag vest 3 on the patient, and fix the airbag vest 3 with the straps 31 and buckles. According to the size of the user, leave a fist's distance between the inner wall of the airbag vest 3 and the patient's body; Then, the limit frame 51 is pressed to move the card plate 63 out of the card slot 52, and then the knob 64 is used to drive the rotating seat 62 to rotate counterclockwise. At this time, the card plate 63 is separated from the limit frame 51. Then, according to the patient's body size, the approximate location of the sputum in the patient's body is determined, and then the mounting ring 5 is rotated to rotate the direction of the limit frame 51 to the direction in which the docking tube 42 needs to be displaced. In this process, the rotating seat 62 can drive the mounting rod 8 and the gear 81 to rotate synchronously. At this time, the gear 81 cooperates with the rack 72 to drive the transmission frame 7 toward the mounting cavity. 61, and the block 71 is retracted into the installation cavity 61 through the connection port. At this time, the block 71 is separated from the limiting tooth 44, and the limiting effect of the slider 6 is released. At this time, the installation ring 5 can be rotated normally, and the limiting frame 51 is used to drive the slider 6 to rotate along the limiting groove 43. After rotating the installation ring 5, manually move the docking tube 42, and use the good ductility of the silicone film 41 to adjust the position of the docking tube 42. After the position of the docking tube 42 is adjusted, press the limiting frame 51 again. At this time, the rotating seat 62 is driven to rotate clockwise again by the knob 64. The pin is pressed, so that the card plate 63 is aligned with the corresponding card slot 52 of the limit frame 51, and then the limit frame 51 is released. At this time, the limit frame 51 begins to rebound, so that the card plate 63 is stuck in the corresponding card slot 52. At this time, the docking pipe 42 can be limited and fixed, so that the docking pipe 42 is always in this position. In this process, when the rotating seat 62 is rotated clockwise, the rotating seat 62 will continue to drive the mounting rod 8 and the gear 81 to rotate synchronously clockwise. At this time, the gear 81 cooperates with the rack 72 to drive the transmission frame 7 to move toward the upper connection port of the slider 6, and the block 7 is 1 will enter the limiting groove 43 of the fixing ring 4 through the connecting port and be stuck between the limiting teeth 44 at the corresponding position. At this time, when the clamping plate 63 is stuck in the clamping groove 52 of the limiting frame 51, since the rotating seat 62 is limited, the mounting rod 8 will also be limited. Due to the mutual engagement between the gear 81 and the rack 72, the transmission frame 7 and the clamping block 71 will be automatically limited. At this time, the limited clamping block 71 cooperates with the limiting teeth 44 to limit the slider 6. At this time, the slider 6 cooperates with the limiting frame 51 to limit the mounting ring 5. During the rotation of the mounting ring 5, the balancing frame 53 will rotate synchronously with the mounting ring 5. At this time, the balancing frame 53 will drive the balancing weight 9 to rotate along the limiting groove 43 of the fixing ring 4. Since the balancing frame 53 and the limiting frame 51 are symmetrically distributed, and the balancing weight 9 cooperates with the limiting plate 91 to limit the balancing frame 53, the balancing frame 53 and the limiting frame 51 cooperate to ensure that the docking tube 42 is always in a horizontal alignment with the fixing ring 4. Then, insert one end of the bellows 45 into the docking port 12 on the main housing 1, and dock the other end of the bellows 45 with the docking tube 42. Then, press the control switch 13 to start the device. The device is set through the controller 22 according to the patient's age and body shape. After adjustment, the fan 21 starts to run, and the fan 21 inhales air through the air inlet 11 and transmits the air to the pulse main unit 2. At this time, the pulse main unit 2 will transport the air through the bellows 45 to the airbag vest. 3, at this time the airbag vest 3 is inflated and bulges, and then the fan 21 draws out the air in the airbag vest 3 through the air inlet 11 and discharges it to the outside of the main body shell 1. When the frequency reaches a certain height, the airbag vest 3 starts to vibrate. Through this high-frequency oscillation, it simulates the chest wall oscillation caused by coughing, relaxes and liquefies the mucus and metabolites on the surface of the expiratory tract mucosa, makes them smaller and looser, and falls off. When the sputum moves from the bronchi to the main trachea, it is discharged from the body by coughing or artificial suction, and the sputum removal work can be completed.
