Description

Technical Field

[0001] This invention relates to the field of hospital bandaging technology, and in particular to a stump bandaging device and a stump bandaging method. Background Technology

[0002] The stump refers to the proximal end remaining after the distal end of a limb has been severed.

[0003] Currently, standard stump bandaging methods include circular bandaging and spiral bandaging. Circular bandaging is the most basic method, with the following steps: A. Cover the wound with a sterile dressing and secure it. B. Unwrap the bandage, making the first loop slightly angled, approximately 45 degrees; then tuck a corner of the first loop into the second loop. C. Apply pressure and wrap the bandage around the limb 4 to 5 times, each loop covering the previous one, ensuring the bandage extends beyond the edge of the dressing. D. Trim off any excess bandage and secure it with adhesive tape. Alternatively, the end of the bandage can be cut lengthwise into two strips and tied. C. Spiral bandaging is often used for limbs or torsos of similar thickness. The steps are: A. Cover the wound with a sterile dressing and secure it. B. Wrap the bandage two times in a circular pattern. C. Starting from the third loop, wrap each loop in a spiral shape, covering one-third or one-half of the previous loop. D. Finally, end with a circular bandage.

[0004] Regardless of the existing method used for stump bandaging, wrapping gauze and bandages is quite cumbersome and requires both hands. In addition, it is often necessary to support the patient's limbs and hold the dressing in the early stages of wrapping to prevent it from moving. Therefore, stump bandaging often requires two people to perform, as it is difficult for one person to do it alone. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a stump bandaging device that can assist in stump bandaging and facilitate stump bandaging.

[0006] The technical solution adopted to solve the above problems is: the stump bandage includes a bandaging aid and a bandaging sleeve;

[0007] The bandaging aid includes an airbag, an airbag seat, an exhaust valve, a handle, a piston, a piston rod, a telescopic claw, and a telescopic claw drive mechanism. The airbag, airbag seat, and handle are coaxially arranged and connected from front to back. The exhaust valve is installed on the airbag seat and opens when the airbag is compressed. The handle is hollow, with the piston located inside and engaging with it. The piston rod is connected to the piston and extends outside the handle. The handle, piston, and piston rod together form an air pump that inflates the airbag. The telescopic claw includes at least three claw bodies, each evenly spaced around the airbag, and hinged to the airbag seat. The telescopic claw drive mechanism drives each claw body to swing, causing the front end of the telescopic claw to open and close.

[0008] The bandage is an elastic sleeve with a U-shaped cross-section. The bandage is located inside the tensioning claw, and the opening of the bandage is folded outward and fitted onto the front end of the tensioning claw.

[0009] Furthermore, the bandaging aid includes an inflation valve and an air inlet valve. The airbag seat has a connecting hole and an air inlet. The connecting hole connects the airbag to the handle. The air inlet extends from the outer surface of the airbag seat to the connecting hole. The inflation valve is located at the front end of the connecting hole and is installed on the airbag seat. The inflation valve is a one-way valve that can open in the direction of the airbag. The air inlet valve is located at the air inlet and is installed on the airbag seat. The air inlet valve is a one-way valve that can open inward.

[0010] Furthermore, the retractable claw drive mechanism includes a spring, a drive sleeve, and a connecting rod; the handle has a positioning flange; the drive sleeve is fitted onto the handle and located in front of the positioning flange; the connecting rod is arranged in a one-to-one correspondence with the claw body, and the two ends of the connecting rod are respectively hinged to the claw body and the drive sleeve; the spring is fitted onto the handle and located between the airbag seat and the drive sleeve, the spring pushes the drive sleeve back so that the drive sleeve abuts against the positioning flange, and the connecting rod drives the claw body to swing inward; when the drive sleeve moves forward, the connecting rod drives the claw body to swing outward.

[0011] Furthermore, the rear end of the drive sleeve has a push flange.

[0012] Furthermore, the stub wrapper includes a rear cover, which is threaded to the rear end of the handle and covers the piston rod.

[0013] Furthermore, the claw body has hooks, and the bandage has loops that hang on the hooks.

[0014] Furthermore, the bandage is a mesh sleeve.

[0015] Another technical problem this invention aims to solve is to provide a more convenient method for bandaging stumps.

[0016] The technical solution adopted to solve the above problems is: a stump bandaging method, which uses the stump bandaging device mentioned above to bandage the stump, and the specific steps are as follows:

[0017] A. Use an air pump to inflate the airbag until it expands.

[0018] B. Cover the stump with a dressing;

[0019] C. Operate the tensioning claw drive mechanism to open the tensioning claw; hold the handle to make the bottom of the bandage stick to the dressing, and the airbag presses against the bandage and dressing;

[0020] D. Advance bandaging aid; the airbag is compressed, the exhaust valve opens to release air, the airbag gradually shortens and continuously presses against the bandage and dressing; the bandage continues to move forward and covers the stump;

[0021] E. Operate the tension-retraction claw drive mechanism to shrink the tension-retraction claw and press it against the residual end, then remove the bandaging sleeve from the tension-retraction claw; then operate the tension-retraction claw drive mechanism again to open the tension-retraction claw and retract the bandaging aid away from the residual end.

[0022] F. Wrap the dressing with gauze and bandage to further bandage the stump.

[0023] The beneficial effects of this invention are as follows: 1. In the steps of bandaging the stump using the stump bandager of this invention, steps A and B can undoubtedly be performed by one person. In step C, one hand holds the stump and dressing to prevent the dressing from moving, while the other hand holds the bandaging aid; this can still be performed by one person. In step D, one hand holds the stump, and the other hand holds the bandaging aid; this can still be performed by one person. As the bandaging aid moves forward, it covers the stump, making it impossible to hold the dressing by hand, but the airbag holds the bandage and dressing in place, preventing the dressing from shifting. In step E, one hand holds the bandaging aid, and the other hand removes the bandage; this can still be performed by one person. After step E is completed, the bandage is placed on the stump, effectively performing preliminary bandaging; this is faster than existing technologies. When further bandaging with a bandage, since preliminary bandaging has been performed and the bandage has fixed the dressing, step F is relatively simple to operate and can also be performed by one person.

[0024] It is evident that this invention simplifies stump bandaging, allowing a single person to perform stump bandaging, thus reducing the workload of nurses and the number of personnel required. Attached Figure Description

[0032] The components in the diagram are labeled as follows: Bandaging aid 1, airbag 101, airbag seat 102, connecting hole 1021, air inlet 1022, handle 103, positioning flange 1031, piston 104, piston rod 105, tension / retraction claw drive mechanism 106, drive sleeve 1061, spring 1062, connecting rod 1063, push flange 1064, tension / retraction claw 107, claw body 1071, hook 1072, exhaust valve 108, inflation valve 109, air inlet valve 110, rear cover 111, bandaging sleeve 2, hanging ear 21, dressing 3. Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] The present invention utilizes an elastic bandage sleeve 2 to cover the stump and then the dressing 3 for initial bandaging, facilitating further bandaging. If the bandage sleeve 2 is applied manually, it requires both hands to expand it and secure it; furthermore, since the bandage sleeve 2 covers the stump, it's impossible to hold and stabilize the dressing 3; this not only requires two people but also carries the risk of dressing displacement. Therefore, the present invention further incorporates a bandaging aid 1.

[0035] like Figures 1 to 4 As shown, the stump bandaging device includes a bandaging assistant 1 and a bandaging sleeve 2; the bandaging assistant 1 includes an airbag 101, an airbag seat 102, an exhaust valve 108, a handle 103, a piston 104, a piston rod 105, a tension / retraction claw 107, and a tension / retraction claw drive mechanism 106; the airbag 101, airbag seat 102, and handle 103 are coaxially arranged and connected from front to back; the exhaust valve 108 is installed on the airbag seat 102, and the exhaust valve 108 opens when the airbag 101 is compressed; the handle 103 is a hollow structure, the piston 104 is located inside the handle 103 and cooperates with the handle 103, and the piston rod 105 is connected to the piston 104. The handle 103, piston 104, and piston rod 105 are connected to and extend to the outside of the handle 103. The handle 103, piston 104, and piston rod 105 form an air pump that can inflate the air bag 101. The expansion and contraction claw 107 includes at least three claw bodies 1071, each claw body 1071 is evenly spaced around the air bag 101, and the claw body 1071 is hinged to the air bag seat 102. The expansion and contraction claw drive mechanism 106 can drive each claw body 1071 to swing, so that the front end of the expansion and contraction claw 107 opens and closes. The bandage 2 is an elastic sleeve with a U-shaped cross-section. The bandage 2 is located inside the expansion and contraction claw 107, and the opening of the bandage 2 is folded outward and fitted onto the front end of the expansion and contraction claw 107.

[0036] The specific steps for bandaging the residual suffocation using the aforementioned residual bandage are as follows: A. Inflate the airbag 101 with an air pump to make the airbag 101 inflated.

[0037] B. Cover the stump with dressing 3;

[0038] C. Operate the tensioning claw drive mechanism 106 to open the tensioning claw 107; hold the handle 103 to make the bottom surface of the bandage 2 stick to the dressing 3, and the airbag 101 presses against the bandage 2 and the dressing 3.

[0039] D. Advance bandaging aid 1; the airbag 101 is compressed, the exhaust valve 108 opens to release air, the airbag 101 gradually shortens and continuously presses against the bandaging sleeve 2 and dressing 3; the bandaging sleeve 2 continues to move forward and is placed on the stump;

[0040] E. Operate the tension and retraction claw drive mechanism 106 to shrink the tension and retraction claw 107 and press it against the end of the wound. Remove the bandaging sleeve 2 from the tension and retraction claw 107. Then operate the tension and retraction claw drive mechanism 106 to open the tension and retraction claw 107 and retract the bandaging aid 1 away from the end of the wound.

[0041] F. Wrap the dressing with gauze and bandage to further bandage the stump.

[0042] Steps A and B can undoubtedly be performed by one person. In step C, one hand holds the stump and dressing 3 to prevent dressing 3 from moving, while the other hand holds the bandaging aid 1; this can still be performed by one person. In step D, one hand holds the stump, and the other hand holds the bandaging aid 1; this can still be performed by one person. As the bandaging aid 1 moves forward, it covers the stump, making it impossible to hold dressing 3 by hand. However, the airbag 101 holds the bandaging sleeve 2 and dressing 3, preventing dressing 3 from shifting. In step E, one hand holds the bandaging aid 1, and the other hand removes the bandaging sleeve 2; this can still be performed by one person. After step E, the bandaging sleeve 2 is placed on the stump, effectively performing initial bandaging; this is faster than existing technologies. When further bandaging with a bandage, since initial bandaging has been performed and the bandaging sleeve 2 also secures dressing 3, step F is relatively simple and can also be performed by one person.

[0043] Obviously, the bandaging sleeve 2 of this invention is for single use only, while the bandaging aid 1 is for repeated use. The bandaging aid 1 can be disinfected after use.

[0044] The function of the airbag 101 is to hold the dressing 3 in place and prevent it from shifting. The pressure of the airbag 101 is determined by the exhaust valve 108. In step D above, moving the bandage aid 1 forward increases the pressure exerted by the airbag 101 on the dressing 3 and the residual dressing. As the airbag 101 is compressed, the exhaust valve 108 opens to release air, causing the airbag 101 to gradually shrink. The gas pressure inside the airbag 101 is maintained at the opening pressure of the exhaust valve 108. Therefore, the function of the exhaust valve 108 is to ensure that the airbag 101 exerts appropriate pressure on the dressing 3. This pressure is low enough to prevent the dressing 3 from shifting, but should not cause significant pressure on the residual dressing. The opening pressure of the exhaust valve 108 should be approximately 1.1 atmospheres. The airbag 101 can be made of plastic film.

[0045] The handle 103, piston 104, and piston rod 105 form an air pump that inflates the airbag 101. For continuous inflation, a corresponding valve should be provided. Specifically: The bandaging aid 1 includes an inflation valve 109 and an air inlet valve 110. The airbag seat 102 has a connecting hole 1021 and an air inlet 1022. The connecting hole 1021 connects the airbag 101 and the handle 103. The air inlet 1022 extends from the outer surface of the airbag seat 102 to the connecting hole 1021. The inflation valve 109 is located at the front end of the connecting hole 1021 and is installed on the airbag seat 102. The inflation valve 109 is a one-way valve that can open towards the airbag 101. The air inlet valve 110 is located at the air inlet 1022 and is installed on the airbag seat 102. The air inlet valve 110 is a one-way valve that can open inwards.

[0046] Pulling the piston rod 105 outward closes the inflation valve 109 and opens the air intake valve 110, allowing air to enter the handle 103. Then, pushing the piston rod 105 inward opens the inflation valve 109 and closes the air intake valve 110, allowing air from the handle 103 to enter the air bladder 101. Repeating this pushing and pulling motion several times in this manner inflates the air bladder 101. When the air bladder 101 is fully inflated, its front end should be approximately flush with the front end of the retracting claw 107.

[0047] The claw body 1071 is hinged to the airbag seat 102, as follows: Figure 2 As shown, multiple slots can be provided on the airbag seat 102 for inserting the rear part of the claw body 1071. The rear part of the claw body 1071 is oriented in the inward and outward directions, and there is still a section of the claw body 1071 inside the hinge point between the claw body 1071 and the airbag seat 102. The connecting rod 1063 is hinged to the inner end of the rear part of the claw body 1071.

[0048] The retractable claw drive mechanism 106 is used to drive the retractable claw 107 to open and close. Its specific structure is preferably as follows: The retractable claw drive mechanism 106 includes a spring 1062, a drive sleeve 1061, and a connecting rod 1063; the handle 103 has a positioning flange 1031; the drive sleeve 1061 is fitted on the handle 103 and located in front of the positioning flange 1031; the connecting rod 1063 is arranged in a one-to-one correspondence with the claw body 1071, and the two ends of the connecting rod 1063 are respectively hinged to the claw body 1071 and the drive sleeve 1061; the spring 1062 is fitted on the handle 103 and located between the airbag seat 102 and the drive sleeve 1061. The spring 1062 pushes the drive sleeve 1061, causing the drive sleeve 1061 to abut against the positioning flange 1031, and the connecting rod 1063 drives the claw body 1071 to swing inward; when the drive sleeve 1061 moves forward, the connecting rod 1063 drives the claw body 1071 to swing outward.

[0049] Holding handle 103 in this manner, the thumb of the hand pushes the drive sleeve 1061 forward, causing the connecting rod 1063 to swing the claw body 1071 outward. Releasing the thumb, the spring 1062 returns to its original position, pushing the drive sleeve 1061 backward, causing the connecting rod 1063 to swing the claw body 1071 inward.

[0050] To facilitate pushing the drive sleeve 1061 with the thumb, the rear end of the drive sleeve 1061 preferably has a push flange 1064. Pushing the push flange 1064 with the thumb pushes the drive sleeve 1061 forward.

[0051] A further preferred residual bandaging device includes a rear cover 111, which is threaded to the rear end of the handle 103 and covers the piston rod 105. Opening the rear cover 111 allows the piston rod 105 to be pushed or pulled. The rear cover 111 covering the piston rod 105 serves both a protective function and makes the bandaging aid 1 more aesthetically pleasing.

[0052] The opening of the bandage 2 is folded outwards and fitted onto the front end of the tensioning claw 107. Because the bandage 2 is elastic, it prevents slippage. To further prevent accidental slippage of the bandage 2, the following settings can be made: Figure 5 As shown, the claw body 1071 has a hook 1072, and the bandage 2 has a hanging ear 21, which is hung on the hook 1072.

[0053] The bandage 2 is preferably a mesh sleeve.
