Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to a pressurization recovery system. Background Art

[0002] Deep vein thrombosis (DVI) is a serious and potentially life-threatening disease. The cause is poor blood circulation in the limbs. Insufficient venous blood flow can form blood clots, leading to local blood vessel blockage; in severe cases, life-threatening blood clots may form in the lungs or heart. A large number of medical studies have shown that improving or accelerating deep vein return in the limbs can prevent deep vein thrombosis. A generally accepted preventive measure is to apply pressure to the corresponding position of the limb. This treatment is usually called "compression therapy."

[0003] At present, pressure bandages are generally used in combination with massage to achieve the effect of "pressure therapy". However, manual massage requires high skills from the operator, and the force is easily uneven, which is labor-intensive. The existing massagers with health care and treatment functions on the market cannot be directly matched with pressure bandages, which imposes great restrictions on users and is inconvenient to operate. Summary of the invention

[0004] In order to achieve the effect of simple operation and convenient use, the present application provides a pressurization recovery system.

[0005] The following technical solutions are adopted:

[0015] A first connecting structure is provided between the front pieces of the two half garments and between the back pieces of the two half garments for connecting the two half garments to form a pressurized garment.

[0016] By adopting the above technical solution, the pressure garment formed by splicing two halves of the garment can be convenient for the user to wear.

[0017] Optionally, the compression garment further comprises:

[0018] The widening band can be filled between the front pieces or the back pieces of the two halves of the garment, and both sides of the widening band can be spliced ​​with the first connecting structure.

[0019] By adopting the above technical solution, when the size of the compression garment needs to be adjusted to meet the needs of different users, the compression garment can be disassembled into two halves and the widening band can be filled between the front and / or back pieces of the two compression garments to adapt to different user body shapes.

[0020] Optionally, the compression garment further comprises:

[0021] The two ends of the shoulder strap can be connected to the front piece and the back piece of any half garment.

[0022] By adopting the above technical solution, when only half of the garment is needed, the shoulder strap can be taken and the two ends of the shoulder strap can be connected to the front piece and the half piece of the half garment respectively. Then, the half garment can be worn on the user's upper body and hung obliquely on the user's shoulders through the shoulder strap, so that the half garment can be worn, meeting practical needs.

[0023] Optionally, the pressurizing component includes:

[0024] Two split trouser legs, one side of each split trouser leg is provided with a second connection structure along the length direction thereof, and the second connection structure can unfold the split trouser leg.

[0025] By adopting the above technical solution, when in use, two or a single split trouser legs can be selected for wearing according to needs. When wearing, the split trouser legs are first directly unfolded to a plane through the second connecting structure, and then the split trouser legs are wrapped around the legs of the wearer, and then the separated sides of the split trouser legs are connected through the second connecting structure.

[0027] One side of the trouser legs of the compression pants is provided with a third connection structure along the length direction thereof, and the third connection structure can unfold the trouser legs of the compression pants.

[0028] By adopting the above technical solution, when wearing, the two trouser legs of the compression pants are directly spread out through the third connecting structure, and then the two trouser legs of the compression pants are wrapped around the legs of the wearer, and then the separated sides of the compression pants are connected through the third connecting structure, and the compression pants can be put on, which reduces the wearing difficulty of the wearer, is simple to operate, and is easy to use.

[0030] A connection structure four is provided between the two ends of the pressure belt, and the connection structure four can change the size of the ring surrounded by the pressure belt.

[0031] By adopting the above technical solution and using the connection structure 4 to adjust the ring size of the pressure belt, the pressure belt can be adapted to different parts of different users to meet different usage requirements.

[0032] Optionally, the airway tube set includes an airway tube;

[0033] The air bag is fixed with an air nozzle for connecting to an airway;

[0034] A safety balloon is fixed to one end of the air nozzle located in the airbag;

[0035] One side of the safety balloon is concave and connected to the air nozzle, and an air outlet is provided on the concave side of the safety balloon, which is connected to the air bag;

[0036] A sealing strip is correspondingly arranged between the insurance balloon and the airbag, and the sealing strip is arranged on the side of the air outlet away from the air nozzle. After the insurance balloon and the airbag are expanded to form, the sealing strip can seal the insurance balloon and the airbag.

[0037] By adopting the above technical solution, as the airbag and the insurance balloon gradually expand, the sealing clip seals the airbag and the insurance balloon, and the airbag can no longer be inflated, thereby avoiding the explosion of the airbag.

[0038] Optionally, an elastic claw is fixed to the end of the air guide tube;

[0041] An air channel is arranged in the air nozzle, and the gas between the air bag and the safety ball enters the air channel to push the extrusion block to squeeze the elastic claw to disengage from the clamping groove.

[0042] By adopting the above technical solution, after the airbag and the insurance balloon are sealed by the sealing clip strip, the gas pressure between the airbag, the insurance balloon and the air nozzle increases, the gas will enter the airway, and then push the extrusion block to move, thereby pushing the extrusion block to squeeze the elastic claw of the airway tube, so that the elastic claw is separated from the slot, the airway tube and the air nozzle quickly lose connection, and the gas in the airway tube will no longer be filled in the airway. At this time, the gas in the airbag will be discharged, but because the airbag and the insurance balloon are still sealed by the sealing clip strip, the airbag will not be exhausted at this time. On the other hand, the insurance balloon after exhaust increases the space in the airbag, which will reduce the internal pressure of the airbag and prevent the airbag from being in a high-pressure state all the time. Moreover, the balloon in the airbag will also push the insurance balloon after exhaust to continue to squeeze the inner surface of the airbag, ensuring that the gas in the airbag will not be discharged. When it is necessary to exhaust the gas in the airbag, any long rod is inserted through the air nozzle to push the insurance balloon to separate the sealing clip strip between the insurance balloon and the airbag to achieve exhaust of the airbag.

[0043] In summary, the present application includes at least one of the following beneficial technical effects:

[0044] When in use, the air pump is connected to the airbag of the pressurizing component through the airway tube group, and then the pressurizing component is put on the limb to wrap the limb. Finally, the air pump is used to inflate the airbag of the pressurizing component through the airway tube group to expand the airbag of the pressurizing component, so that the limb wrapped by the pressurizing component can be pressurized. When use is finished, the airbag of the pressurizing component can be deflated. It is easy to use and simple to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0055] The following is combined with Figure 1-9 This application is described in further detail.

[0056] The embodiment of the present application discloses a pressurization recovery system, which is mainly used for pressurization treatment of a user's limbs and can simplify operation and improve ease of use.

[0057] Reference Figure 1 , a pressurization recovery system includes an air pump 1, an air guide tube group 2 and a pressurization component 3.

[0058] The air pump 1 serves as an air source power output end, and is used to transport gas into the pressurizing component 3 to change the shape of the pressurizing component 3 .

[0059] The pressurized component 3 is used to wrap around the user's limbs. As the main unit for achieving pressurized therapy, the interior of the pressurized component 3 mainly includes a plurality of mutually isolated air bags 31, and the pressurized component 3 can be surrounded in a ring shape, so that the pressurized component 3 can be wrapped around the corresponding limb part according to needs, and then pressurized gas is input into each air bag 31 of the pressurized component 3 through the air pump 1, so as to achieve the effect of pressurizing the part of the limb surrounded by the pressurized component 3.

[0060] The air guide tube group 2 serves as the main connection unit for connecting the air pump 1 and each air bag 31 of the pressurizing component 3. The air guide tube group 2 includes a plurality of air guide tubes 21, one end of each of the plurality of air guide tubes 21 is connected to the air pump 1, and the other end of each of the plurality of air guide tubes 21 can be respectively connected to each air bag 31 of the pressurizing component 3, so that the air source output by the air pump 1 can be delivered to each air bag 31 of each pressurizing component 3 through the air guide tube 21. In order to facilitate the storage of the overall device and improve the portability, both ends of the air guide tube group 2 can be connected to the air pump 1 and the pressurizing component 3 in a detachable connection manner, such as by plug-in matching, snap-on matching, bolt matching, etc., which can achieve a fixed and disassembled connection method.

[0061] The solution provided by this embodiment achieves the following goals: the air pump 1 is connected to the air bags 31 of the pressurizing component 3 through a plurality of air guide tubes 21, and then the pressurizing component 3 is sleeved on the limb to wrap the limb; finally, the air pump 1 is used to inflate the air bags 31 of the pressurizing component 3 through the air guide tubes 21 to expand the air bags 31 of the pressurizing component 3, thereby pressurizing the limb wrapped by the pressurizing component 3; when use is finished, the air bags 31 of the pressurizing component 3 are deflated, and the air pump 1, the air guide tubes 21 and the pressurizing component 3 are separately disassembled and stored for use on the lower side, which is convenient to use and simple to operate.

[0062] Reference Figure 2 In another embodiment of the present application, in order to realize that one air pump 1 can be connected to multiple pressurizing components 3 at the same time, a branch pipe group 4 can be additionally provided to connect the air pump 1 with multiple air guide tube groups 2, thereby realizing the inflation use of multiple pressurizing components 3.

[0063] The branch pipe group 4 specifically includes a plurality of branch pipes 41, one end of which is commonly fixed with a plug connector for plugging with the air pump 1, and the other end of which is commonly fixed with a branch joint 42. The branch joint 42 can be provided with two connection parts for respectively connecting with two groups of air guide tube groups 2, that is, the branch joint 42 can divide the output end of one branch pipe into multiple output ends for connecting with the air guide tube 21 of the air guide tube group 2. The connection between the branch joint 42 and the air guide tube group 2 can also be achieved by plugging, or by a clamping bolt connection or other connection methods. When the air pump 1 needs to be used to connect three or more groups of air guide tube groups 2 at the same time, the branch joint 42 can also be provided with three or more connection parts that can be connected with the air guide tube group 2 to meet different needs.

[0064] In summary, when multiple pressurizing components 3 need to be used at the same time, the air guide tube group 2 can be pulled out from the air pump 1, and one end of the plug connector of the decomposition tube group can be connected to the air pump 1, and then the multiple air guide tube groups 2 can be connected to the branch connectors 42 respectively, so as to realize the inflation and pressurization operation of multiple pressurizing components 3 by one air pump 1.

[0065] In another embodiment of the present application, the pressure component 3 may include an upper limb pressure component, a lower limb pressure component and a local pressure component, which are further described in detail below.

[0066] Reference Figure 3 The upper limb pressurization component mainly includes a pressurization garment 5. The pressurization garment 5 includes two half garments 51, and the two half garments 51 are symmetrically arranged along the connecting line of the front center and the back center of the pressurization garment 5, so as to realize dividing the pressurization into two symmetrical parts. The multiple air bags 31 in the half garment 51 can be arranged along the length direction of the sleeve toward the front center and the back center of the half garment 51. A first connecting structure is arranged between the front pieces of the two half garments 51 and before the back pieces of the two half garments 51, wherein the first connecting structure is mainly used to realize splicing the two half garments 51 into the pressurization garment 5, or decomposing the pressurization garment 5 into the two half garments 51, so as to facilitate the user to wear it conveniently. Therefore, the first connecting structure can adopt a detachable connecting method such as a zipper, Velcro, snap fasteners, rope buckles, etc.

[0067] Reference Figure 3 In order to increase the wearing range of the compression garment 5 and adapt it to people of more body shapes, the compression garment 5 may further include an enlarged band 52. One or two enlarged bands 52 may be provided. The enlarged band 52 is used to fill between the front piece or the back piece of the two half garments 51, and cooperate with the two half garments 51 to increase the adaptable range of the compression garment 5. In order to further increase the adaptable range of the compression garment 5, the enlarged band may also be made of elastic material.

[0068] Since the widening belt 52 is used to fill between the two halves of the garment 51 , first adapting connection structures adapted to the first connection structures of the two halves of the garment 51 are provided on both sides of the widening belt 52 . The first adapting connection structure is selected according to the selection of the first connection structure to ensure the connection between the two halves of the garment 51 and the widening belt 52 .

[0069] In this way, the setting of the widening band 52 achieves the goal that when the size of the compression garment 5 needs to be adjusted to meet the needs of different users, after the compression garment 5 is disassembled into two halves 51, the widening band 52 can be taken out and filled between the front and / or back pieces of the two compression garments 5, so as to adapt to different user body shapes.

[0070] Reference Figure 4 In order to facilitate the use of the half garment 51 alone, the compression garment 5 further includes a shoulder strap 53. The shoulder strap 53 is used to be connected to any half garment 51, so that when the user only needs to wear the half garment 51, the shoulder strap 53 can be hung obliquely on the shoulder position of the side of the body where the half garment 51 is not worn while wearing the half garment 51 connected with the shoulder strap 53, thereby achieving the wearing of the half garment 51.

[0071] In order to facilitate the connection between the shoulder strap 53 and any half garment 51, connecting components are provided at both ends of the shoulder strap 53, and the connecting method of the connecting components can still adopt the same connecting method as the first connecting structure.

[0072] In addition, in order to facilitate adaptation to different body shapes of the wearer, the connecting parts between the shoulder strap 53 and any half garment 51 can adopt an adjustable connection method, such as setting one side of the shoulder strap 53 along its length with a velvet belt or hook belt of a velvet fastener, and setting the connecting part of the half garment 51 corresponding to the shoulder strap 53 in a form that can be adapted to the velvet belt or hook belt of the shoulder strap 53 to form a velvet fastener, so that the connection length between the shoulder strap 53 and the half garment 51 can be adjusted.

[0073] In this way, the setting of the shoulder strap 53 achieves the goal that when only the half garment 51 is needed, the shoulder strap 53 can be taken out and the two ends of the shoulder strap 53 can be respectively connected to the front piece and the half piece of the half garment 51. Then, the half garment 51 can be worn on one side of the user's upper body and hung obliquely on the other shoulder of the user's upper body through the shoulder strap 53, so that either half garment 51 can be worn.

[0074] Reference Figure 1 and Figure 5The lower limb pressurizing component is divided into two forms, one is in the form of a split trouser leg 6, and the other is in the form of a pressurizing trouser 61. The main difference between the two is that the split leg exists independently and can only be wrapped around one leg of the user, while the pressurizing trouser 61 can simultaneously wrap the user's legs up to the waist. The split trouser leg 6 and the airbags 31 in the pressurizing trouser 61 can be arranged in sequence along the length direction of the trouser leg. In order to increase the pressurizing effect of the pressurizing trouser 61 and the split trouser leg 6, the lower sides of the legs of the split trouser leg 6 and the pressurizing trouser 61 can be extended to wrap part of the foot, that is, only the front toes or the front toes and the front sole of the foot of the user are exposed to avoid squeezing the user's feet during the pressurization process.

[0075] To ensure wearing comfort, the split trouser legs 6 include two, which are respectively used to be worn on the front leg and the back leg of the user. To facilitate wearing of the split trouser legs 6, one side of the split trouser legs 6 is provided with a second connection structure along its length direction, which can be used to unfold the split trouser legs 6. The second connection structure can be used in the same manner as the first connection structure, so that the split trouser legs 6 can be unfolded and wrapped around the user's legs, and then the split trouser legs 6 can be connected.

[0076] The setting of the split trouser legs 6 allows the user to choose two or a single split trouser legs 6 to wear according to needs. When wearing, the split trouser legs 6 are first directly unfolded to a plane through the second connecting structure, and then the split trouser legs 6 are wrapped around the wearer's legs. The separated sides of the split trouser legs 6 are then connected through the second connecting structure to complete the wearing of the split trouser legs 6, which reduces the wearing difficulty of the wearer.

[0077] To facilitate wearing of the compression pants 61, the compression pants 61 adopts the same wearing method as the split pants, that is, a third connection structure is provided on one side of both trouser legs of the compression pants 61 along the length direction thereof, and the third connection structure is used to spread the two trouser legs of the compression pants 61, so that the two trouser legs can be quickly worn and wrapped around the user's legs. Similarly, the third connection structure can adopt the same connection method as the first connection structure, which will not be repeated here.

[0078] When the compression pants 61 are worn, similarly, the two trouser legs of the compression pants 61 are spread out using the third connecting structure, and then the two trouser legs of the compression pants 61 are wrapped around the legs of the wearer, and then the separated sides of the compression pants 61 are connected using the third connecting structure, and the compression pants 61 can be worn.

[0079] Reference Figure 6The application scope of the local pressure component is wider than that of the upper limb pressure component and the lower limb pressure component, and it can be used for pressure treatment of any local position of the limb. The local pressure component includes a pressure belt 7, and the airbags 31 in the pressure belt 7 are arranged in sequence along the length direction of the pressure belt 7, and can also be arranged along one side of the width direction of the pressure belt 7. The pressure belt 7 is a belt body structure whose two ends can be connected to each other to form a ring shape. In order to realize that the pressure belt 7 can be formed into rings of different sizes, a fourth connection structure is arranged at both ends of the pressure belt 7.

[0080] The fourth connecting structure adopts an adjustable connection method, such as a nylon buckle connection method, that is, a velvet belt and a hook belt are respectively provided at the two ends of the pressure belt 7, and the length of either the velvet belt or the hook belt is extended along the length of the pressure belt 7, so as to achieve the pressure belt 7 to be wrapped in a ring of different sizes through the cooperation of the nylon buckle; another example is a parent-child snap button connection method, that is, the parent-child snap buttons are respectively fixed to the two ends of the pressure belt 7, and the number of child buckles or mother buckles at either end of the pressure belt 7 is set to be multiple, and they are all arranged along the length direction of the pressure belt 7, so as to achieve the pressure belt 7 to be wrapped in a ring of different sizes through different parent-child snap button cooperation. The above two forms of the fourth connecting structure are only used as examples, and do not mean that the fourth connecting structure can only adopt the above forms, that is, any connection method that can achieve adjustable positions at both ends of the pressure belt 7 is possible.

[0081] Reference Figure 4 In another embodiment of the present application, the connection method between the airway tube assembly 2 and the airbag 31 of the pressurizing component 3 is further described in detail:

[0082] An air nozzle 32 is fixed at each air bag 31 of the pressurizing component 3, and each air tube 21 of the air tube group 2 can be plugged into the air nozzle 32 of each air bag 31, so as to realize the connection between each air bag 31 and one end of each air tube 21 of the air tube group 2. In order to ensure the connection between the air nozzle 32 and the air tube 21 and prevent the air tube 21 from being separated from the air nozzle 32 when the air bag 31 moves, a pressing sheet 33 is provided on the outer side of the pressurizing component 3 corresponding to the air nozzle 32, one side of the pressing sheet 33 is fixed to the pressurizing component 3, and the other side of the pressing sheet 33 is detachable for easy opening, such as Velcro, snap buttons or zipper.

[0083] In this way, when it is necessary to connect the air duct 21 and the air bag 31 of the pressurizing component 3, open the movable end of the clamping sheet 33, connect one end of each air duct 21 to the air nozzle 32 of the pressurizing component 3, and then press the clamping sheet 33 against the air duct 21 and the air nozzle 32, and connect the movable side of the clamping sheet 33 to the pressurizing component 3, so as to further fix the air nozzle 32 and the air duct 21, and avoid the separation of the air duct 21 and the air nozzle 32. The operation is simple and ensures the safety of use on the one hand, and avoids the separation of the air nozzle 32 and the air duct 21 due to the activities of the actual user on the other hand, so as to facilitate the use of the user.

[0084] In another embodiment of the present application, the air pump 1 is described in detail:

[0085] Reference Figure 7 The air pump 1 includes a housing 11, in which an air outlet nozzle 12, a power supply compartment 13, a DC pump core 14 and a solenoid valve 15 are mainly arranged. The air outlet nozzle 12 is installed on the housing 11, and the number of air outlet holes 342 of the air outlet nozzle 12 is determined according to the number of air guide tubes 21 of the air guide tube group 2, so as to realize that each air outlet hole 342 corresponds to each air guide tube 21, so as to respectively deliver airflow to each air guide tube 21 through each air outlet hole 342.

[0086] The power supply compartment 13 is used to store the power supply, and the DC pump core 14 can be electrically connected to the power supply through the power supply compartment 13, thereby providing power for the DC pump core 14. The power supply can be an integrated rechargeable power supply fixed in the power supply compartment 13, or a rechargeable power supply that can be disassembled from the power supply compartment 13, or a disposable battery.

[0087] The electromagnetic valve 15 is connected between the DC pump core 14 and the air outlet nozzle 12, and the air flow output by the DC pump core 14 is delivered to the air outlet nozzle 12 through the electromagnetic valve 15. The number of the electromagnetic valves 15 is determined according to the size of the housing 11 and the number of the air outlet holes 342 of the air outlet nozzle 12.

[0088] This embodiment is described by taking the case where the number of the air outlet holes 342 of the air outlet nozzle 12 is six.

[0089] There are two solenoid valves 15, which are installed on both sides of the housing 11. A three-way valve is connected between the two solenoid valves 15. The three ends of the three-way valve are respectively connected to the output end of the DC pump core 14 and the output ends of the two solenoid valves 15. The output end of each solenoid valve 15 is simultaneously connected to the three air outlet holes 342 of the air outlet nozzle 12. Through the movement of the valve core of the solenoid valve 15, the output end of the solenoid valve 15 and the three air outlet holes 342 are switched to multiple states such as being connected separately, connected at the same time, and blocked at the same time (the solenoid valve 15 is a prior art and will not be described here). In addition, different airflow states of the air outlet holes 342 of the air outlet nozzle 12 can be achieved, so that different modes such as pressurizing a single or partial airbag 31 of the pressurizing component 3, pressurizing multiple airbags 31 in sequence, and pressurizing multiple airbags 31 at the same time can be achieved, thereby meeting different usage requirements.

[0090] In order to further improve the protection of the DC pump core 14 and the electromagnetic valve 15 , a filter box can be installed between the electromagnetic valve 15 and the air outlet nozzle 12 .

[0091] In another embodiment of the present application, the connection method between the air nozzle 32 of the pressurizing component 3 and the air guide tube 21 of the air guide tube assembly 2 is further described in detail.

[0092] Reference Figure 8 and Fig. 9 The air duct 21 is inserted into one end of the air nozzle 32 of the pressurizing component 3 and a clamping structure is formed between the air nozzle 32. The clamping structure includes an elastic claw 23 connected to the circumference of the air duct 21. The elastic claw 23 can keep its end away from the end of the air duct 21 protruding from the circumference of the air duct 21 through its own elasticity. Pressing the elastic claw 23 can make the end of the elastic claw 23 protruding from the circumference of the air duct 21 shrink to the circumference of the air duct 21. The clamping structure also includes a clamping groove 321 opened on the inner circumferential surface of the air nozzle 32 of the pressurizing component 3. When the air duct 21 is inserted into the air nozzle 32, the elastic claw 23 can be compressed to enable the air duct 21 to be inserted into the air nozzle 32. When the air duct 21 is inserted to the position where the elastic claw 23 is located in the clamping groove 321, the elastic claw 23 will be pushed by its own elasticity to be inserted into the clamping groove 321 and limit the air duct 21 from being separated from the air nozzle 32, thereby achieving the connection and fixation of the air duct 21 and the air nozzle 32.

[0093] The outer circumference of the air nozzle 32 is connected to a squeezing block 322 at a position corresponding to each slot 321 and the squeezing block 322 can move along the slot 321. When the air nozzle 32 needs to be disassembled, the squeezing block 322 is squeezed to squeeze the elastic claw 23 of the air guide tube 21 through the squeezing block 322, so that the air guide tube 21 can be separated from the air nozzle 32.

[0094] A safety component is provided between the air guide tube 21 and the air nozzle 32 to limit the maximum air pressure input into the airbag 31 to prevent the airbag 31 from bursting.

[0095] The safety component includes a safety balloon 34, which is a spherical structure with a curved concave surface on one side after being filled with air, and the strength of the safety balloon 34 is greater than that of the airbag 31. An air inlet 341 is provided at the center of the curved concave surface of the safety balloon 34, and the air inlet 341 of the safety balloon 34 is fixed to and communicated with one end of the air nozzle 32 located in the airbag 31.

[0096] An air outlet hole 342 is provided on the outer side of the recessed portion of the safety balloon 34 corresponding to the air inlet 341, and the air outlet hole 342 connects the interior of the safety balloon 34 with the interior of the airbag 31. When the airbag 31 is inflated, the gas entering from the air nozzle 32 will first enter the safety balloon 34, and then be sent to the airbag 31 through the air outlet hole 342 of the safety balloon 34 to inflate the airbag 31. As the airbag 31 is inflated, both the airbag 31 and the safety balloon 34 will gradually expand into shape. When the airbag 31 and the safety balloon 34 expand to a predetermined state, the setting of the state is related to the strength of the airbag 31, that is, when the airbag 31 expands to a state close to but below its critical explosion point, the side of the safety balloon 34 close to the air nozzle 32 will be pressed against the inner surface of the airbag 31 around the air nozzle 32.

[0097] A sealing clamp strip 311 is provided at the position where the airbag 31 and the safety balloon 34 can abut against each other after being inflated, that is, the airbag 31 and the safety balloon 34 are respectively fixed with an annular sealing convex strip and an annular sealing concave strip. As the airbag 31 and the safety balloon 34 gradually expand, the sealing convex strip will be buckled into the sealing concave strip to achieve fixation, thereby closing the abutting portion of the airbag 31 and the safety balloon 34, so that the airbag 31 can no longer be inflated.

[0098] The air nozzle 32 is located at one end of the air bag 31 and is provided with an air passage 323 connected to the card slot 321. An air receiving groove 324 is formed between the extrusion block 322 and the air nozzle 32 at a position corresponding to the air passage 323. After the air bag 31 and the safety balloon 34 are sealed by the sealing clip 311, the gas pressure between the air bag 31, the safety balloon 34 and the air nozzle 32 increases, and the gas will enter the air passage 323, and then push the extrusion block 322 to move, thereby pushing the extrusion block 322 to squeeze the elastic claw 23 of the air guide tube 21, so that the elastic claw 23 is separated from the card slot 321, the air guide tube 21 and the air nozzle 32 are quickly disconnected, and the gas in the air guide tube 21 will no longer be filled in the air passage 323. At this time, the gas in the airbag 31 will be discharged, but because the airbag 31 and the safety balloon 34 are still sealed by the sealing strip 311, the air in the airbag 31 will not be exhausted at this time. On the other hand, the deflated safety balloon 34 increases the space in the airbag 31, which will reduce the internal pressure of the airbag 31 and prevent the airbag 31 from being in a high-pressure state all the time. Furthermore, the balloon in the airbag 31 will also push the deflated safety balloon 34 to continue squeezing the inner surface of the airbag 31, ensuring that the gas in the airbag 31 will not be discharged. When it is necessary to discharge the gas in the airbag 31, any long rod can be inserted through the air nozzle 32 to push the safety balloon 34 to separate the sealing strip 311 between the safety balloon 34 and the airbag 31 to achieve the exhaust of the airbag 31.

[0099] In order to avoid the danger caused by the air guide tube 21 being directly separated from the air nozzle 32 after the elastic claw 23 is separated from the slot 321, further configurations may be provided:

[0100] Reference Figure 8The position between the air nozzle 32 and the limit ring 321 is provided with an exhaust limit opening 325. When the air guide tube 21 is inserted into the air nozzle 32, the elastic claw 23 can be inserted into the exhaust limit opening 325. The air guide tube 21 is continuously pushed, so that the elastic claw 23 of the air guide tube 21 can go over the exhaust limit opening 325 and continue to go deep into the air nozzle 32 until the elastic claw 23 is clamped in the clamping groove 321, thereby completing the fixation of the air guide tube 21 and the air nozzle 32. When the elastic claw 23 of the air guide tube 21 is separated from the clamping groove 321 and leaves the air nozzle 32, the elastic claw 23 of the air guide tube 21 can be inserted into the exhaust limit opening 325. The claw 23 will be clamped in the exhaust limit opening 325 again, limiting the air guide tube 21 from being separated from the air nozzle 32. At this time, the gas ejected from the air guide tube 21 can be quickly discharged from the exhaust limit opening 325, avoiding the danger of the air guide tube 21 being separated from the air nozzle 32 in the jetting state. When the air pump 1 is turned off and the air guide tube 21 is separated from its air nozzle 32, the elastic claw 23 is squeezed through the exhaust limit opening 325 and merged with the circumference of the air guide tube 21, so that the air guide tube 21 can be quickly pulled out of the air nozzle 32, thereby realizing the disassembly and assembly of the air guide tube 21 and the air nozzle 32.

[0101] 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.
