Description

Technical Field

[0001] The present application relates to the field of inflatable equipment, and in particular to an inflatable device and a sputum removal vest. Background Art

[0002] As an auxiliary medical device, the expectoration vest is gaining more and more attention in clinical applications. It helps patients expel phlegm from their lungs by simulating the effect of patting, significantly improving their recovery speed and quality of life. Traditional expectoration methods rely on manual operation, which is time-consuming, labor-intensive and has unstable effects. The emergence of the expectoration vest has greatly improved this situation. This device can not only evenly distribute vibrations throughout the back, but also adapt to the needs of different patients through adjustable intensity, thereby ensuring the effectiveness and safety of treatment.

[0003] In the prior art, the expectoration vest mainly includes a vest body, a vibrator fixedly mounted on the vest body, a controller and a battery. Among them, the vest body is generally designed to be inflatable, and is inflated by a built-in air pump to expand the vest body and make close contact with the human body, thereby better transmitting the vibration effect. In addition, the controller is used to control the working state of the vibrator, and the battery is responsible for powering the entire system to ensure the normal operation of the device.

[0004] However, the air pump installed in the existing expectoration vest will significantly increase the overall weight of the vest, which not only affects the wearing comfort of the patient, but also may cause discomfort after wearing for a long time. Summary of the invention

[0005] In order to improve the wearing comfort of the expectoration vest, the present application provides an inflation device and an expectoration vest.

[0006] The present application provides an inflatable device and a sputum removal vest, which adopt the following technical solutions: An inflation device comprises a valve body, one end of the valve body is connected to an air guide hose, the end of the air guide hose away from the valve body is used to be connected to a sputum removal vest, the end of the valve body away from the air guide hose is connected to an air cushion, the interior of the valve body is sequentially provided with a support ring, a first spring, a blocking block and a blocking ring, the peripheral side of the support ring and the peripheral side of the blocking ring are both fixedly connected to the inner wall of the valve body, the first spring is fixedly installed between the blocking block and the support ring, the first spring is used to drive the blocking block to move toward the blocking ring, the blocking block is provided with a limiting opening, a limiting rod is passed through the limiting opening, the valve body is provided with a driving mechanism, the driving mechanism is used to drive the limiting rod to move to avoid the blocking block.

[0007] By adopting the above technical solution, when using the expectoration vest, the air guide hose is connected to the expectoration vest, and the weight of the inflation device is not imposed on the patient, thereby improving the comfort of wearing the expectoration vest. After that, the patient wears the expectoration vest and sits on the air cushion. The weight of the patient squeezes the air cushion, so that the air inside the air cushion enters the expectoration vest from the valve body and the air guide hose, thereby facilitating the inflation of the expectoration vest. After the expectoration vest is pressed against the patient's body, the driving mechanism drives the limit rod to move, so that the limit rod releases the blocking block, and the first spring drives the blocking block to press the blocking ring, and the air in the air cushion stops flowing to the expectoration vest, thereby facilitating the control of the pressing force of the expectoration vest on the patient, thereby improving the comfort of wearing the expectoration vest.

[0008] Optionally, the driving mechanism includes a first shrinkable hood, a second shrinkable hood, a bellows, a driving plate and a boosting assembly, the first shrinkable hood and the second shrinkable hood are both fixedly mounted on the outer wall of the valve body, the first shrinkable hood and the second shrinkable hood are both connected to the interior of the valve body, one end of the bellows is fixedly connected to an end of the first shrinkable hood away from the valve body, the other end of the bellows is fixedly connected to the driving plate, one end of the limit rod is slidably penetrated into the interior of the first shrinkable hood and is fixedly connected to the driving plate, the other end of the limit rod is slidably penetrated into the interior of the second shrinkable hood, and the boosting assembly is used to apply pressure to the driving plate to move toward the valve body.

[0009] By adopting the above technical solution, when the patient sits on the air cushion, the air inside the air cushion enters the valve body, thereby increasing the air pressure inside the valve body. The increase in air pressure inside the valve body pushes the drive plate to move away from the valve body, thereby facilitating the removal of the limit rod from the limit port, and further facilitating the first spring to drive the blocking block to press the blocking ring for sealing.

[0010] Optionally, the boost assembly includes a boost hood, a first pressure plate, a driving rod, a second pressure plate and a second spring. The boost hood is fixedly mounted on an end of the first shrinking hood away from the valve body, the bellows and the driving plate are located inside the boost hood, the first pressure plate and the second pressure plate are both slidably disposed inside the boost hood, the second spring is fixedly mounted between the first pressure plate and the second pressure plate, the second spring is used to drive the first pressure plate and the second pressure plate away from each other, and the driving rod thread passes through a side of the boost hood away from the first shrinking hood.

[0011] By adopting the above technical solution, the driving rod is rotated to adjust the length of the driving rod inside the second shrink cover, thereby limiting the sliding range of the second pressing plate inside the second shrink cover. By adjusting the sliding range of the second pressing plate inside the second shrink cover, it is convenient to adjust the pressure of the spring driving the first pressing plate to press the bellows, and then it is convenient to adjust the air pressure required for the limit rod to pull out the limit port.

[0012] Optionally, a plurality of first tooth blocks are fixedly mounted on the rod body of the limiting rod, and a plurality of second tooth blocks are fixedly mounted on the inner wall of the limiting opening. The first tooth blocks and the second tooth blocks are both spaced apart along the length direction of the limiting rod, and the space between two adjacent first tooth blocks is used for the second tooth blocks to enter.

[0013] By adopting the above technical solution, when the first tooth block and the second tooth block abut against each other, the blocking block is blocked, the blocking block is away from the blocking ring, and the valve body is opened, so that the air inside the air cushion can enter the sputum discharge vest from the valve body and the air guide hose. When the first tooth block and the second tooth block are misaligned with each other, the first spring drives the blocking block to press the blocking ring, so as to facilitate closing the valve body.

[0014] Optionally, both sides of the first tooth block and both sides of the second tooth block are arc-shaped, the side of the first tooth block and the second tooth block facing each other is flat, a ball is embedded on the side of the first tooth block close to the second tooth block, the support ring is located on the side of the sealing block close to the air cushion, and the inner diameter of the support ring is smaller than the inner diameter of the sealing ring.

[0015] By adopting the above technical solution, when the expectoration vest is worn, the air pressure inside the valve body increases, so that the limit rod moves away from the second shrink cover. When the limit rod moves away from the second shrink cover, the friction between the first gear block and the second gear block is reduced by the ball bearing, so that the limit rod moves away from the second shrink cover to be unlocked.

[0016] When the expectoration vest needs to be deflated and taken off after use, the driving rod is rotated, and the driving rod pushes the limiting rod to move inside the second shrink cover through the first pressing plate, the second pressing plate and the second spring. The limiting rod is pressed against each other by the arc-shaped side walls of the first tooth block and the second tooth block, so that the blocking block is away from the blocking ring. After the flat positions of the first tooth block and the second tooth block are against each other, the limiting rod re-locks the blocking block.

[0017] Optionally, a first support plate is fixedly installed on one side of the air cushion close to the valve body, a first telescopic tube is installed on the top surface of the first support plate, a second telescopic tube is slidably inserted inside the first telescopic tube, an end of the second telescopic tube away from the first support plate is sealed, a driving hose is arranged inside the first telescopic tube, one end of the driving hose is fixedly connected to the top end of the second telescopic tube, and the other end of the driving hose is arranged along the first support plate and connected to the air cushion.

[0018] By adopting the above technical solution, when the patient sits on the air cushion, the air inside the air cushion enters the driving hose, thereby expanding the driving hose. After the driving hose expands, the driving hose drives the second telescopic tube to extend, and the second telescopic tube supports the expectoration vest, thereby improving the comfort of wearing the expectoration vest.

[0019] Optionally, the cross-sections of the first telescopic tube and the second telescopic tube are both rectangular, a second support plate is provided at the top end of the second telescopic tube, the second support plate is provided with a sliding opening, the top end of the second telescopic tube is passed through the sliding opening, and the top end of the second telescopic tube is provided with a support groove for the second support plate located at the edge of the sliding opening to enter.

[0020] By adopting the above technical solution, different patients will have some differences in body shape. By moving the second support plate to support the expectoration vest, it is convenient to reduce the pressure of the expectoration vest on the patient, thereby improving the comfort of the patient wearing the expectoration vest.

[0021] Optionally, a receiving groove is provided on the top surface of the first support plate, and the bottom end of the first telescopic tube is hinged to the inner wall of the receiving groove, and the receiving groove is used for the first telescopic tube to enter after rotating to be horizontal.

[0022] By adopting the above technical solution, when the air cushion needs to be stored, the first telescopic tube is rotated to enter the storage groove, thereby facilitating the storage of the air cushion.

[0023] Optionally, a plurality of shunt pipes connected in a staggered manner horizontally and vertically are fixedly installed on the inner top wall of the air cushion, a supporting hose is fixedly installed between the tube body of the shunt pipe and the inner bottom wall of the air cushion, and an airbag is arranged on the peripheral side of the air cushion, and the airbag is connected to the shunt pipe.

[0024] By adopting the above technical solution, when the air cushion needs to be used, the airbag is pressed, and the gas inside the airbag enters the supporting hose, and the supporting hose expands the airbag, thereby facilitating the use of inflating the airbag.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-8 This application is described in further detail.

[0031] The embodiments of the present application disclose an inflation device and a sputum removal vest.

[0032] Reference Figure 1 , Figure 2, an inflation device comprises a valve body 1, one end of the valve body 1 is connected to an air hose 2, and the end of the valve body 1 away from the air hose 2 is fixedly connected to an air cushion 3. The air hose 2 is connected to a sputum discharge vest, and the patient sits on the air cushion 3 after wearing the sputum discharge vest. The air cushion 3 is squeezed by the patient's own gravity, and the air inside the air cushion 3 flows to the sputum discharge vest, so that the sputum discharge vest can be closely attached to the patient. The inflation device of the present application is separated from the sputum discharge vest, and can realize the inflation function without increasing the weight of the sputum discharge vest, thereby improving the comfort of the patient wearing the sputum discharge vest.

[0033] Reference Figure 3 , Figure 4 , a support ring 4, a first spring 5, a blocking block 6 and a blocking ring 7 are sequentially arranged inside the valve body 1 from one end close to the air cushion 3 to the other end. The peripheral side of the support ring 4 and the peripheral side of the blocking ring 7 are fixedly connected to the inner wall of the valve body 1, and the first spring 5 is fixedly installed between the blocking block 6 and the support ring 4. The first spring 5 is used to drive the blocking block 6 to move toward the blocking ring 7. When the blocking block 6 is tightly against the blocking ring 7, the valve body 1 is closed, so that the gas inside the air cushion 3 stops flowing to the sputum discharge vest; when the blocking block 6 is separated from the blocking ring 7, the valve body 1 is opened, so as to facilitate the gas inside the air cushion 3 to flow to the sputum discharge vest.

[0034] Reference Figure 3 , Figure 4 The blocking block 6 is provided with a limit opening 8, and a limit rod 9 is inserted inside the limit opening 8. A plurality of first tooth blocks 10 are fixedly mounted on the rod body of the limit rod 9, and a plurality of second tooth blocks 11 are fixedly mounted on the inner wall of the limit opening 8. The first tooth blocks 10 and the second tooth blocks 11 are arranged at intervals along the length direction of the limit rod 9. The space between two adjacent first tooth blocks 10 is used for the second tooth blocks 11 to enter.

[0035] After the limiting rod 9 is pulled to align the first tooth block 10 and the second tooth block 11, the limiting rod 9 abuts against each other through the first tooth block 10 and the second tooth block 11, thereby limiting the first spring 5 from pushing the blocking block 6 against the blocking ring 7, thereby facilitating the air inside the air cushion 3 to flow from the valve body 1 and the air guide hose 2 to the sputum discharge vest. After the limiting rod 9 is pulled to misalign the first tooth block 10 and the second tooth block 11, the second tooth block 11 enters between two adjacent first tooth blocks 10, and the first tooth block 10 enters between two adjacent second tooth blocks 11, thereby facilitating the first push of the blocking block 6 against the blocking ring 7, thereby facilitating the closing of the valve body 1.

[0036] The first tooth block 10 and the second tooth block 11 are arranged flat on one side facing each other, and a ball 12 is embedded on the side of the first tooth block 10 close to the second tooth block 11. When the limiting rod 9 is pulled to make the first tooth block 10 and the second tooth block 11 misaligned, the ball 12 converts the sliding friction into rolling friction, so that it is convenient to pull the limiting rod 9 to move.

[0037] Both sides of the first tooth block 10 and the second tooth block 11 are arc-shaped. When the blocking block 6 needs to be separated from the blocking ring 7, the limiting rod 9 is pulled, and the side walls of the first tooth block 10 and the second tooth block 11 are squeezed against each other. The arc-shaped side walls of the first tooth block 10 and the second tooth block 11 facilitate pulling the limiting rod 9 to drive the blocking block 6 to separate from the blocking ring 7.

[0038] Reference Figure 3 , Figure 4 The valve body 1 is provided with a driving mechanism 13, and the driving mechanism 13 includes a first shrinking cover 131, a second shrinking cover 132, a bellows 133, a driving plate 134 and a booster assembly 135. The first shrinking cover 131 and the second shrinking cover 132 are both fixedly mounted on the outer wall of the valve body 1, and the first shrinking cover 131 and the second shrinking cover 132 are both connected to the inside of the valve body 1. One end of the bellows 133 is fixedly connected to the end of the first shrinking cover 131 away from the valve body 1, and the other end of the bellows 133 is fixedly connected to the driving plate 134. One end of the limit rod 9 is slidably disposed inside the first shrinking cover 131 and is fixedly connected to the driving plate 134, and the other end of the limit rod 9 is slidably disposed inside the second shrinking cover 132.

[0039] When the patient sits on the air cushion 3, the pressure inside the valve body 1 increases. The pressure inside the valve body 1 squeezes the driving plate 134 away from the valve body 1, so that the limiting rod 9 overcomes the friction between the first gear block 10 and the second gear block 11 and the pressure of the booster assembly 135 and moves toward the inside of the first shrink cover 131. After the limiting rod 9 moves into the first shrink cover 131, the first gear block 10 and the second gear block 11 are staggered, so that it is convenient for the first spring 5 to drive the blocking block 6 to press the blocking ring 7, thereby facilitating the automatic closing of the valve body 1.

[0040] Reference Figure 3 , Figure 4 , the inner diameter of the support ring 4 is smaller than the inner diameter of the blocking ring 7. The small inner diameter of the support ring 4 reduces the amount of air passing through the support ring 4, thereby facilitating the slow deflation of the air cushion 3 after being compressed. Since the inner diameter of the blocking ring 7 is larger than the inner diameter of the support ring 4, the air inside the valve body 1 is accelerated to flow to the expectoration vest. When the expectoration vest is not full of air, the air pressure inside the valve body 1 is low, thereby reducing the movement of the limit rod 9 when the expectoration vest is not full of air.

[0041] Reference Figure 3 , Figure 4The boost assembly 135 includes a boost cover 1351, a first pressure plate 1352, a driving rod 1353, a second pressure plate 1354 and a second spring 1355. The boost cover 1351 is fixedly mounted on the end of the first shrink cover 131 away from the valve body 1, and the bellows 133 and the driving plate 134 are located inside the boost cover 1351. The first pressure plate 1352 and the second pressure plate 1354 are both slidably arranged inside the boost cover 1351, and the second spring 1355 is fixedly mounted between the first pressure plate 1352 and the second pressure plate 1354. The elastic force of the second spring 1355 is used to drive the first pressure plate 1352 and the second pressure plate 1354 away from each other. The driving rod 1353 is threadedly penetrated through the side of the boost cover 1351 away from the first shrink cover 131.

[0042] The driving rod 1353 is rotated to adjust the length of the driving rod 1353 inside the pressurizing cover 1351. By adjusting the length of the driving rod 1353 inside the pressurizing cover 1351, the moving range of the second pressing plate 1354 inside the pressurizing cover 1351 is adjusted, thereby facilitating the adjustment of the pressure applied by the second spring 1355 to the driving plate 134 through the first pressing plate 1352. By adjusting the pressure applied by the first pressing plate 1352 to the driving plate 134, the air pressure required for closing the valve body 1 is conveniently adjusted, thereby facilitating the adjustment of the pressing force of the expectoration vest on the patient after inflation.

[0043] Reference Figure 2 , Figure 5 A first support plate 14 is fixedly mounted on one side of the airbag 28 close to the valve body 1, a storage groove 15 is provided on the top surface of the first support plate 14, and a first telescopic tube 16 is hingedly mounted on the inner wall of the storage groove 15. When the air cushion 3 needs to be stored, the first telescopic tube 16 is rotated horizontally to enter the storage groove 15, so as to facilitate the storage of the air cushion 3.

[0044] Reference Figure 5 , Figure 6 A second telescopic tube 17 is slidably inserted into the first telescopic tube 16. The second telescopic tube 17 cannot be pulled out of the first telescopic tube 16. One end of the second telescopic tube 17 away from the first support plate 14 is sealed. A driving hose 18 is arranged inside the first telescopic tube 16. One end of the driving hose 18 is fixedly connected to the top of the second telescopic tube 17. The other end of the driving hose 18 is arranged along the first support plate 14 and connected to the air cushion 3.

[0045] When the patient sits on the air cushion 3, the air inside the air cushion 3 enters the driving hose 18, and the driving hose 18 is inflated and straightened, thereby extending the second telescopic tube 17. After the patient stands up from the air cushion 3, the second telescopic tube 17 moves downward due to gravity, so that the air inside the driving hose 18 returns to the inside of the air cushion 3.

[0046] Reference Figure 5 , Figure 6The cross-sections of the first telescopic tube 16 and the second telescopic tube 17 are both rectangular, and a second support plate 19 is provided at the top of the second telescopic tube 17. The second support plate 19 is provided with a sliding opening 29, and the top of the second telescopic tube 17 is passed through the sliding opening 29. The top of the second telescopic tube 17 is provided with a support groove 20 for the second support plate 19 to enter at the edge of the sliding opening 29.

[0047] The second support plate 19 is moved by the sliding opening 29, so that the support plate is conveniently moved to the bottom of the expectoration vest and away from the back of the patient. When the second telescopic tube 17 moves upward, the second telescopic tube 17 drives the second support plate 19 to support the expectoration vest, thereby reducing the pressure of the expectoration vest on the patient, thereby improving the comfort of the patient wearing the expectoration vest.

[0048] The second support plate 19 is elastic, so that it is convenient to remove the second support plate 19 from the second telescopic tube 17 after the sliding opening 29 is opened.

[0049] Reference Figure 2 , Figure 3 The inner top wall of the air cushion 3 is fixedly installed with a plurality of shunt pipes 21 connected in a horizontal and vertical manner, and a support hose 22 is fixedly installed between the tube body of the shunt pipe 21 and the inner bottom wall of the air cushion 3. The side wall of the air cushion 3 is fixedly installed with an air bag 28, which is connected to the shunt pipe 21.

[0050] When the air cushion 3 is needed, the airbag 28 is pressed, and the air inside the airbag 28 enters the support hose 22 from the shunt pipe 21, thereby straightening the support hose 22. After the support hose 22 is straightened, the support hose 22 opens the air cushion 3, thereby facilitating the air cushion 3 to be filled with air.

[0051] Reference Figure 7 , Figure 8 A sputum removal vest includes a vest body 23, a gas-filled joint 24 is fixedly mounted on the vest body 23, and the gas-filled joint 24 is connected to an airway. A plurality of vibrators 25 are fixedly mounted on the vest body 23, and a controller 26 and a battery 27 are mounted on the back side of the vest body 23. The battery 27 is used to power the controller 26 and the vibrator 25, and the controller 26 is used to turn the vibrator 25 on and off.

[0052] After the patient wears the expectoration vest, the vibrator 25 is started by the controller 26, and the vibrator 25 vibrates and pats the patient, thereby facilitating the patient to expectorate. After expectoration ends, the vibrator 25 is turned off by the controller 26.

[0053] The implementation principle of the inflatable device and the expectoration vest of the embodiment of the present application is as follows: when the expectoration vest is needed to expectorate the patient, the expectoration vest and the inflatable device are taken out, the airbag 28 is pressed to straighten the support hose 22 and then the air cushion 3 is expanded, and air enters the air cushion 3 from the air guide hose 2 and the valve body 1.

[0054] After the air cushion 3 is inflated, the air guide hose 2 is connected to the inflation connector 24 on the expectoration vest. According to the required pressing force of the expectoration vest on the patient, the pressure of the booster assembly 135 on the driving plate 134 is adjusted. Then the patient wears the expectoration vest and sits on the air cushion 3.

[0055] When the patient sits on the air cushion 3, the air inside the air cushion 3 enters the expectoration vest from the valve body 1 and the air guide hose 2, so that the expectoration vest expands and fits closely to the patient's body, thereby facilitating the vibrator 25 to vibrate and expectorate the patient.

[0056] After the expectoration vest is pressed against the patient's body, the air pressure inside the valve body 1 is high, so that the driving plate 134 moves away from the valve body 1. The driving plate 134 drives the limiting rod 9 to move inside the first shrink cover 131, so that the first tooth block 10 and the second tooth block 11 are misaligned. Then the first spring 5 drives the blocking block 6 to press the blocking ring 7, so as to close the valve body 1, and the air inside the air cushion 3 stops flowing to the expectoration vest.

[0057] After closing the valve body 1, the vibrator 25 is started to vibrate through the controller 26, so as to facilitate the patient to expectorate. After the patient finishes expectorating, the patient stands up from the air cushion 3, and then the booster assembly 135 drives the limit rod 9 to move inside the second shrink cover 132. The limit rod 9 is squeezed by the first tooth block 10 and the second tooth block 11, thereby driving the blocking block 6 to separate from the blocking ring 7. After that, the air inside the expectoration vest returns to the inside of the air cushion 3 from the air guide hose 2 and the valve body 1, so as to facilitate the patient to take off the expectoration vest.

[0058] If no other patient needs to use the expectoration vest later, the air guide hose 2 is pulled out from the inflation connector 24 to release the air inside the air cushion 3, thereby facilitating the storage of the air cushion 3 and the expectoration vest.

[0059] In the present application, when a patient wears the expectoration vest, the weight of the inflatable device is not applied to the patient, thereby improving the comfort of wearing the expectoration vest.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
