Description

An emergency treatment tool for frostbite on the legs Technical Field

[0001] This invention relates to the field of medical technology, specifically to an emergency treatment tool for frostbite on the legs. Background Technology

[0002] Frostbite is a localized or systemic injury caused by cold and dampness. Mild cases may cause transient skin damage requiring immediate treatment; severe cases can lead to permanent functional impairment, necessitating professional medical care. In extreme cases, it can be life-threatening, requiring emergency treatment.

[0003] The basic goals of frostbite treatment are rapid rewarming, prevention of further cold exposure, and restoration of blood circulation. Early treatment of frostbite includes covering the affected area or other body surfaces with clothing or warm hands to maintain an appropriate temperature and adequate blood supply. Rapid water bath rewarming is necessary; the water temperature should be between 37°C and 43°C, and this method is suitable for all types of frostbite.

[0004] In practical use, the traditional emergency treatment for frostbite on the legs is often to rewarm the legs by water bath. If you want to accelerate blood flow in the patient's legs on top of water bath, you need to manually massage the patient's legs, which requires a certain amount of manpower and is relatively complicated.

[0005] Therefore, we propose an emergency treatment tool for frostbite on the legs to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an emergency treatment tool for frostbite of the legs, which has a drive mechanism to drive two massage blocks located in the channel to move in opposite directions to press on the patient's legs, thereby accelerating blood flow in the patient's legs so that the patient's legs can return to normal temperature more quickly. This solves the problem of having to manually massage the patient's legs, which requires a certain amount of manpower.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an emergency treatment tool for frostbite of the legs, comprising a bathtub, wherein two first upright plates are fixed to the bottom surface of the inner wall of the bathtub, and the two first upright plates form a V-shape between them; two second upright plates are vertically fixed to the bottom surface of the inner wall of the bathtub, and the two second upright plates are parallel to the two first upright plates respectively; a channel is formed between the parallel first upright plates and the second upright plates; symmetrically distributed massage blocks are provided in both channels; and a driving mechanism is provided in the bathtub for driving the two opposing massage blocks to move in opposite directions to press the patient's legs.

[0008] Preferably, there are two drive mechanisms, each corresponding to one of the two channels. Each drive mechanism includes two mounting seats located on one side of the second upright plate and vertically fixed to the bottom surface of the inner wall of the bathtub. A cylindrical cam is rotatably connected between the two mounting seats. A fully gear I, coaxially fixed with the cylindrical cam, is provided inside the bathtub. A partially gear that intermittently meshes with the fully gear I is rotatably connected to the surface of one of the mounting seats. The partially gear is driven by an external drive device. A movable plate is fitted on the surface of the cylindrical cam. A slider that matches the groove on the surface of the cylindrical cam is integrally fixedly connected inside the movable plate. A limit rod is fixedly connected to the lower surface of the cylindrical cam. A groove parallel to the cylindrical cam and used for sliding the limit rod is opened on the bottom surface of the inner wall of the bathtub.

[0009] Preferably, the driving mechanism further includes two reversible telescopic rods vertically fixed to the bottom surface of the inner wall of the bathtub. A U-shaped frame is fixedly connected to the top of each reversible telescopic rod. Two U-shaped frames are fixedly connected between the two U-shaped frames. The two U-shaped frames are located directly above the first upright plate and the second upright plate, and are parallel to the first upright plate and the second upright plate, respectively. A horizontal plate is slidably connected within the two U-shaped frames. Four inclined push rods are fixedly connected to the lower surface of the horizontal plate, and the inclined push rods at both ends of the horizontal plate are inclined in opposite directions to form a figure-eight shape.

[0010] Preferably, a plurality of springs are fixedly connected to the opposite side of the first and second upright plates. The free end of each spring is fixedly connected to an I-shaped block. A convex groove that matches the I-shaped block is opened on one side of the surface of the massage block. A bending rod is fixedly connected to the surface of one of the U-shaped frames. A roller is rotatably connected to one end of the bending rod. A limit inclined panel is installed on the upper surface of the movable plate.

[0011] Preferably, the bathtub is provided with a linkage mechanism for driving the inclined push rod to move horizontally along the first upright plate. The linkage mechanism includes a second fully gear that is rotatably connected to the surface of the mounting base and intermittently meshes with the incomplete gear. A threaded rod that is coaxially fixed between the two mounting bases is rotatably connected to the second fully gear.

[0012] Preferably, the threaded rod is threaded with an internal threaded sleeve, and a limit post is vertically fixed on the lower surface of the internal threaded sleeve. The bottom surface of the inner wall of the bathtub is provided with a long groove that is parallel to the threaded rod and is used for sliding of the limit post. A connecting rod is fixedly connected to the upper surface of the internal threaded sleeve, and one end of the connecting rod is telescopically inserted into the horizontal plate.

[0013] Preferably, the limiting inclined plate is rotatably connected to the upper surface of the movable plate. The bathtub is provided with an adjustment mechanism for adjusting the moving distance of the massage block according to the patient's own weight. The adjustment mechanism includes a rectangular box fixedly connected to the bottom surface of the inner wall of the bathtub. A rectangular piston plate is installed in the rectangular box. A telescopic rod is fixedly connected to the lower surface of the rectangular piston plate. The free end of the telescopic rod is fixedly connected to the bottom surface of the inner wall of the rectangular box. A spring is sleeved on the surface of the telescopic rod. The two ends of the spring are fixedly connected to the rectangular box and the rectangular piston plate, respectively. A seat is fixedly connected to the upper surface of the rectangular piston plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. First, fill the bathtub with an appropriate amount of warm water. Then, have the patient with frostbite on their legs sit in the bathtub with their legs placed in the channel. By setting up a drive mechanism, the two massage blocks located in the channel can be moved in opposite directions to press on the patient's legs, thereby accelerating blood flow and helping the patient's legs return to normal temperature more quickly.

[0017] 2. By setting up a linkage mechanism, after the inclined push rod moves upward, it is driven to move horizontally along the first vertical plate, so that the four inclined push rods move directly above the other two massage blocks, so that the inclined push rods can subsequently drive the two massage blocks to move in opposite directions.

[0018] 3. Since each frostbite patient has a different body shape and leg thickness, an adjustment mechanism is set up to adjust the movement distance of the massage block according to the patient's weight. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please refer to Figures 1-4. The present invention provides a technical solution: an emergency treatment tool for frostbite of the legs, including a bathtub 1 and two first upright plates 21 fixed to the bottom surface of the inner wall of the bathtub 1, forming a V-shape between the two first upright plates 21. Two second upright plates 22 are vertically fixed to the bottom surface of the inner wall of the bathtub 1. The two second upright plates 22 are parallel to the two first upright plates 21 respectively. A channel 23 is formed between the parallel first upright plates 21 and the second upright plates 22. Each of the two channels 23 is provided with symmetrically distributed massage blocks 3. The bathtub 1 is provided with a driving mechanism 4 for driving the two opposing massage blocks 3 to move in opposite directions to press the patient's legs.

[0031] In use, first pour an appropriate amount of warm water into the bathtub 1, then let the patient with frostbite on their legs sit in the bathtub 1 and place their legs in the channel 23. By setting the drive mechanism 4, the two massage blocks 3 located in the channel 23 are driven to move in opposite directions to press the patient's legs, so that the blood flow in the patient's legs can be accelerated, so that the patient's legs can return to normal temperature more quickly.

[0032] There are two drive mechanisms 4, and the two drive mechanisms 4 correspond to the two channels 23 respectively.

[0033] The driving mechanism 4 includes two mounting seats 41 located on one side of the second upright plate 22 and vertically fixed to the bottom surface of the inner wall of the bathtub 1. A cylindrical cam 42 is rotatably connected between the two mounting seats 41. A fully gear 43 coaxially fixed with the cylindrical cam 42 is provided inside the bathtub 1. A partially gear 44 intermittently meshes with the fully gear 43 on the surface of one of the mounting seats 41. The partially gear 44 is driven by an external driving device. A movable plate 45 is sleeved on the surface of the cylindrical cam 42. A slider that matches the groove on the surface of the cylindrical cam 42 is integrally fixedly connected inside the movable plate 45. A limit rod 46 is fixedly connected to the lower surface of the cylindrical cam 42. A groove parallel to the cylindrical cam 42 and used for sliding the limit rod 46 is opened on the bottom surface of the inner wall of the bathtub 1.

[0034] The external drive device is a motor.

[0035] In use, the external drive device motor is started to drive the incomplete gear 44 to rotate. The incomplete gear 44 can drive the complete gear 43, which meshes with it intermittently, to rotate intermittently. The complete gear 43 can drive the cylindrical cam 42, which is fixed coaxially with it, to rotate intermittently. The cylindrical cam 42 can drive the movable plate 45 to move intermittently back and forth in the horizontal direction.

[0036] The drive mechanism 4 also includes two reversible telescopic rods 471 that are vertically fixed to the bottom surface of the inner wall of the bathtub 1. A U-shaped frame 472 is fixedly connected to the top of the reversible telescopic rod 471. Two loop frames 473 are fixedly connected between the two U-shaped frames 472. The two loop frames 473 are located directly above the first upright plate 21 and the second upright plate 22, and are parallel to the first upright plate 21 and the second upright plate 22. A horizontal plate 474 is slidably connected inside the two loop frames 473. Four inclined push rods 475 are fixedly connected to the lower surface of the horizontal plate 474, and the inclined push rods 475 at both ends of the horizontal plate 474 are inclined in opposite directions to form a figure-eight shape.

[0037] Several springs 481 are fixedly connected to the opposite side of the first upright plate 21 and the second upright plate 22. The free end of each spring 481 is fixedly connected to an I-shaped block 482. A convex groove that matches the I-shaped block 482 is opened on one side of the surface of the massage block 3.

[0038] During use, if the patient has a wound on their leg, the massage block 3 corresponding to the wound can be removed from the I-shaped block 482 to prevent the wound from being pressed.

[0039] One of the loop frames 473 has a bending rod 491 fixedly connected to its surface. One end of the bending rod 491 is rotatably connected to a roller 492. A limit inclined plate 493 is installed on the upper surface of the movable plate 45.

[0040] In use, the movable plate 45 can drive the limiting inclined plate 493 located on its upper surface to move intermittently in the horizontal direction. The limiting inclined plate 493 can push the bending rod 491 to move intermittently in the vertical direction through the roller 492. The bending rod 491 can drive the loop frame 473 to move intermittently in the vertical direction. The loop frame 473 can drive the horizontal plate 474 to move intermittently in the vertical direction. The horizontal plate 474 can drive the inclined push rod 475 to move intermittently in the vertical direction.

[0041] When the inclined push rod 475 moves downward, it can push the two corresponding massage blocks 3 to move in opposite directions, so that the massage blocks 3 can press the patient's legs. At this time, the spring 481 is stretched.

[0042] When the inclined push rod 475 moves upward and returns to its original position, it can completely disengage from the massage block 3, and the spring 481 can drive the massage block 3 to return to its original position through the rebound force.

[0043] Example 2

[0044] Please refer to Figure 5. This embodiment further illustrates Example 1. The bathtub 1 is provided with a linkage mechanism 5 for driving the inclined push rod 475 to move horizontally along the first upright plate 21.

[0045] In use, by setting the linkage mechanism 5, after the inclined push rod 475 moves upward, it drives the inclined push rod 475 to move horizontally along the first vertical plate 21, so that the four inclined push rods 475 move directly above the other two massage blocks 3, so that the inclined push rods 475 can subsequently drive the two massage blocks 3 to move in opposite directions.

[0046] The linkage mechanism 5 includes a second complete gear 51 rotatably connected to the surface of the mounting base 41 and intermittently meshing with the incomplete gear 44. A threaded rod 52 coaxially fixed between the two mounting bases 41 is rotatably connected to the second complete gear 51. An internal threaded sleeve 53 is threadedly connected to the surface of the threaded rod 52. A limit post 54 is vertically fixed to the lower surface of the internal threaded sleeve 53. A long groove parallel to the threaded rod 52 is opened on the bottom surface of the inner wall of the bathtub 1 for sliding of the limit post 54. A connecting rod 55 is fixedly connected to the upper surface of the internal threaded sleeve 53. One end of the connecting rod 55 is telescopically inserted into the horizontal plate 474.

[0047] In use, the incomplete gear 44 can drive the intermittently meshing complete gear 51 to rotate intermittently. The complete gear 51 can drive the threaded rod 52, which is fixed coaxially with it, to rotate intermittently. The threaded rod 52 can drive the internal threaded sleeve 53 to move intermittently in the horizontal direction. The internal threaded sleeve 53 can drive the connecting rod 55 to move intermittently in the horizontal direction. The connecting rod 55 can drive the horizontal plate 474 to move intermittently in the horizontal direction. The horizontal plate 474 can drive the inclined push rod 475 to move intermittently in the horizontal direction, thereby moving the inclined push rod 475 to directly above the other two massage blocks 3, so that the inclined push rod 475 can subsequently drive the two massage blocks 3 to move in opposite directions.

[0048] Example 3

[0049] Please refer to Figures 6-8. This embodiment further illustrates Example 2. The limiting inclined panel 493 is rotatably connected to the upper surface of the movable plate 45. The bathtub 1 is provided with an adjustment mechanism 6 for adjusting the moving distance of the massage block 3 according to the patient's own weight.

[0050] During use, since each frostbite patient has a different body shape and leg thickness, an adjustment mechanism 6 is set up to adjust the movement distance of the massage block 3 according to the patient's weight.

[0051] The adjustment mechanism 6 includes a rectangular box 61 fixedly connected to the bottom surface of the inner wall of the bathtub 1. A rectangular piston plate 62 is installed inside the rectangular box 61. A telescopic rod 63 is fixedly connected to the lower surface of the rectangular piston plate 62. The free end of the telescopic rod 63 is fixedly connected to the bottom surface of the inner wall of the rectangular box 61. A spring 64 is sleeved on the surface of the telescopic rod 63. The two ends of the spring 64 are fixedly connected to the rectangular box 61 and the rectangular piston plate 62 respectively. A seat 65 is fixedly connected to the upper surface of the rectangular piston plate 62.

[0052] The adjustment mechanism 6 also includes a support plate 66 vertically fixed to the surface of the movable plate 45. A pipe 67 is fixedly connected to the upper surface of the support plate 66. A circular piston plate 691 is installed inside the pipe 67. A vertical rod 692 extending out of the pipe 67 is fixedly connected to the surface of the circular piston plate 691. The upper end of the vertical rod 692 is attached to the lower surface of the limiting inclined plate 493. A load-bearing block 693 is fixedly connected to one end of the limiting inclined plate 493 near the vertical rod 692. A flexible hose 68 is fixedly installed between the rectangular box 61 and the pipe 67.

[0053] In use, when a patient sits on seat 65, the degree to which seat 65 moves downward will vary depending on the patient's weight. When seat 65 moves downward, it can push the gas in rectangular box 61 through hose 68 into pipe 67, thereby pushing the circular piston plate 691 in pipe 67 upward. The circular piston plate 691 can drive the upright rod 692 to move upward, and the upright rod 692 can push the limiting inclined plate 493 to rotate, causing the tilt angle of the limiting inclined plate 493 to change. Therefore, when patients of different weights sit on seat 65, the tilt angle of the limiting inclined plate 493 will be different.

[0054] During use, different tilt angles of the limiting inclined panel 493 will cause different vertical movement distances of the bending rod 491, which in turn will cause different vertical movement distances of the loop frame 473, the horizontal plate 474, and the inclined push rod 475, resulting in different horizontal movement distances of the massage block 3.

[0055] Working principle: This is an emergency treatment tool for frostbite of the legs. When using it, first pour an appropriate amount of warm water into the bathtub 1, then let the patient with frostbite sit in the bathtub 1 and place the patient's legs in the channel 23. Start the external drive device motor to drive the incomplete gear 44 to rotate. The incomplete gear 44 can drive the complete gear 43 that meshes with it to rotate intermittently. The complete gear 43 can drive the cylindrical cam 42 that is fixed on the same axis to rotate intermittently. The cylindrical cam 42 can drive the movable plate 45 to move intermittently back and forth in the horizontal direction.

[0056] The movable plate 45 can drive the limiting inclined plate 493 located on its upper surface to move intermittently in the horizontal direction. The limiting inclined plate 493 can push the bending rod 491 to move intermittently in the vertical direction through the roller 492. The bending rod 491 can drive the loop frame 473 to move intermittently in the vertical direction. The loop frame 473 can drive the horizontal plate 474 to move intermittently in the vertical direction. The horizontal plate 474 can drive the inclined push rod 475 to move intermittently in the vertical direction.

[0057] When the inclined push rod 475 moves downward, it can push the two corresponding massage blocks 3 to move in opposite directions, so that the massage blocks 3 can press the patient's legs. At this time, the spring 481 is stretched.

[0058] When the inclined push rod 475 moves upward and returns to its original position, it can completely disengage from the massage block 3, and the spring 481 can drive the massage block 3 to return to its original position through the rebound force.

[0059] If the patient has a wound on their leg, the massage block 3 corresponding to the wound can be removed from the I-shaped block 482 to prevent the wound from being pressed.

[0060] The incomplete gear 44 can drive the complete gear 51, which meshes with it intermittently, to rotate intermittently. The complete gear 51 can drive the threaded rod 52, which is fixed coaxially with it, to rotate intermittently. The threaded rod 52 can drive the internal threaded sleeve 53 to move intermittently in the horizontal direction. The internal threaded sleeve 53 can drive the connecting rod 55 to move intermittently in the horizontal direction. The connecting rod 55 can drive the horizontal plate 474 to move intermittently in the horizontal direction. The horizontal plate 474 can drive the inclined push rod 475 to move intermittently in the horizontal direction, thereby moving the inclined push rod 475 to directly above the other two massage blocks 3, so that the inclined push rod 475 can subsequently drive the two massage blocks 3 to move in opposite directions.

[0061] When a patient sits on seat 65, the degree to which seat 65 moves downward will vary depending on the patient's weight. As seat 65 moves downward, it pushes the gas in rectangular box 61 through hose 68 into pipe 67, thereby pushing the circular piston plate 691 in pipe 67 upward. The circular piston plate 691 can drive the upright rod 692 to move upward, and the upright rod 692 can push the limiting inclined plate 493 to rotate, causing the tilt angle of the limiting inclined plate 493 to change. Therefore, when patients of different weights sit on seat 65, the tilt angle of the limiting inclined plate 493 will be different.

[0062] During use, different tilt angles of the limiting inclined panel 493 will cause different vertical movement distances of the bending rod 491, which in turn will cause different vertical movement distances of the loop frame 473, the horizontal plate 474, and the inclined push rod 475, resulting in different horizontal movement distances of the massage block 3.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
