Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a warmer for replantation of severed fingers. Background Art

[0002] Finger replantation refers to a high-precision and delicate surgery that reattaches a completely or partially severed finger to its original position under the aid of an optical magnifying glass (microscope), restores blood circulation, and enables it to survive and regain certain functions.

[0003] After finger replantation, the patient's arms and hands need to be kept warm to promote blood circulation and prevent vascular embolism or spasm. However, the existing warming technology still has some defects:

[0004] 1. Most existing technologies use lamp heating to keep the patient's arms and hands warm. During the lamp heating process, the patient's arms and hands are prone to getting hot and the temperature cannot be kept constant, resulting in poor warming effect after flap or finger replantation, affecting the patient's normal recovery;

[0005] 2. At the same time, after finger replantation, it is necessary to ensure normal blood circulation in the patient's arms and hands to prevent ischemia and hypoxia in the surgical site. However, the existing technology is not convenient for the patient to raise his arms and hands for exercise, which has a certain impact on the recovery effect and speed of skin flap or finger replantation.

[0006] In view of the above problems, the inventor proposes a warmer for post-severed finger replantation surgery to solve the above problems. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example: Figure 1-7As shown, the present invention provides a warmer for replantation of severed fingers, comprising a warming box 1, a placement channel 11 is fixedly installed on the inner wall of the warming box 1, a ring-shaped airbag 12 is fixedly installed on the side wall at one end of the placement channel 11, an air inlet pipe 13 is fixedly installed at one end of the placement channel 11, one end of the air inlet pipe 13 is communicated with the inner cavity of the ring-shaped airbag 12, a warming component 2 is provided on the warming box 1, a lifting mechanism 3 is provided inside the placement channel 11, and a blood circulation component 5 is also provided inside the placement channel 11. By arranging the placement channel 11 in the warming box 1, it is convenient to place the patient's arm in the placement channel 11, so that the patient's hand is in the placement channel 11, and by arranging the air inlet pipe 13, it is convenient to fill gas into the ring-shaped airbag 12, so that the ring-shaped airbag 12 expands, and when the patient's arm passes through the ring-shaped airbag 12, the expansion of the ring-shaped airbag 12 can fix the arm. At the same time, the placement channel 11 can be sealed. After the annular airbag 12 contracts, the high-temperature airflow in the placement channel 11 can be evacuated. By setting the warming component 2, the warming component 2 can keep the patient's arms and hands warm, promote blood circulation, prevent vascular embolism and spasm, and compared with the existing technology using lamp heating, it avoids high temperature and fever, thereby improving the warming effect after flap or finger replantation. By setting the lifting mechanism 3, the lifting mechanism 3 can make the patient's arms and hands slowly lift back and forth, thereby accelerating the blood return of the arm, preventing ischemia and hypoxia in the surgical site, and further improving the recovery effect and recovery speed of flap or finger replantation. By setting the blood circulation component 5, the blood circulation component 5 can slowly massage the back of the patient's hand, thereby ensuring the blood circulation of the hand, and further improving the recovery effect and recovery speed of flap or finger replantation.

[0031] A corrugated soft plate 14 is fixedly installed on the side wall at one end of the placement channel 11, and the outer wall of the annular airbag 12 is fixedly connected to the middle part of the corrugated soft plate 14. By setting the corrugated soft plate 14, when the patient's arm passes through the annular airbag 12, as the annular airbag 12 expands, the corrugated soft plate 14 follows the deformation, thereby improving the sealing of the end of the placement channel 11 and preventing the high-temperature airflow in the placement channel 11 from overflowing.

[0032] The warming component 2 includes a U-shaped water tank 21, which is opened inside the warming box 1. An insulating pad 22 is fixedly installed on the side wall of the U-shaped water tank 21, and a thermal conductive pad 23 is fixedly installed on the other side wall of the U-shaped water tank 21. A heater 26 is fixedly installed on the upper end surface of the warming box 1, and the heating plate of the heater 26 is located in the U-shaped water tank 21. A number of evenly distributed air inlet grooves 27 are opened around the placement channel 11. When the water cup to be heated is filled into the U-shaped water tank 21, the heating plate of the heater 26 can heat the water in the U-shaped water tank 21, and the heater 26 has a constant temperature heating function. The insulating pad 22 prevents the water temperature from dissipating through the outer wall of the warming box 1, and the thermal conductive pad 23 conducts the water temperature, so that the inner wall of the warming box 1 heats up quickly, and the high-temperature airflow generated can enter the placement channel 11 through the air inlet groove 27 to keep the patient's arms and hands warm.

[0033] A filling pipe 24 is fixedly installed on the upper end surface of the warming box 1, and one end of the filling pipe 24 is connected to the circular water tank 21. A drain pipe 25 is fixedly installed on one side of the warming box 1, and one end of the drain pipe 25 is connected to the circular water tank 21. By setting the filling pipe 24, it is convenient for medical personnel to fill the water to be heated into the circular water tank 21. By setting the drain pipe 25, the water in the circular water tank 21 can be discharged through the drain pipe 25.

[0034] The lifting mechanism 3 includes a frame plate 31, which is fixedly mounted on the inner wall of the placement channel 11, and a lifting plate 32 is arranged inside the placement channel 11. A fixing plate 34 is fixedly mounted on the lower surface of the frame plate 31, and a swing plate 35 is fixedly mounted on the lower surface of the lifting plate 32. Two rotating shafts 36 are rotatably mounted on one end of the swing plate 35, and one end of the two rotating shafts 36 is fixedly connected to one end of the fixing plate 34. The outer walls of the two rotating shafts 36 are movably sleeved with torsion springs 37, and one end of the two torsion springs 37 is fixedly connected to one end of the fixing plate 34, and the other end of the two torsion springs 37 is fixed to one end of the swing plate 35. The frame plate 31 is connected so that the frame plate 31 can support the patient's arm, and the lifting plate 32 is provided so that the lifting plate 32 can lift the patient's arm and hand. A rotating shaft 36 and a torsion spring 37 are provided. When the swing plate 35 is pushed to move upward, the swing plate 35 can move with the axis of the rotating shaft 36 as the center of the circle. The upward movement of the swing plate 35 can deform the torsion spring 37. The swing plate 35 can lift the patient's hand and arm upward through the lifting plate 32. When the swing plate 35 stops moving upward, the resetting of the torsion spring 37 can cause the swing plate 35 to move downward and reset.

[0035] A cushion 33 is fixedly installed on the upper surface of the frame plate 31 and the lifting plate 32, and a limit seat 38 is fixedly installed on the inner wall of the placement channel 11. The lower surface of the swing plate 35 is in movable contact with the upper surface of the limit seat 38. By providing the cushion 33, the cushion 33 can improve the comfort of the patient's arms and hands. By providing the limit seat 38, when the swing plate 35 moves downward, the limit seat 38 can support the swing plate 35 so that the swing plate 35 always maintains a horizontal state after being lowered.

[0036] A motor 39 is fixedly installed on the bottom wall of the placement channel 11, and a rotating rod 4 is fixedly installed on the driving output end of the motor 39. Two cams 41 are fixedly installed on one end of the rotating rod 4. Two arc seats 42 are fixedly installed on the lower surface of the swing plate 35, and one cam 41 is vertically corresponding to one arc seat 42. By turning on the motor 39, the driving shaft of the motor 39 can rotate the rotating rod 4, the rotating rod 4 can rotate the cam 41, and the cam 41 can move the swing plate 35 upward through the arc seat 42.

[0037] The blood circulation component 5 includes an equipment frame 51, which is fixed in an inclined state on the inner wall of the placement channel 11. The equipment frame 51 is located above the lifting plate 32. A number of evenly distributed rotating rollers 52 are rotatably installed on the inner wall of the equipment frame 51, and sponge covers 53 are fixedly installed on the outer walls of the number of rotating rollers 52. By setting the inclined rotating rollers 52 and sponge covers 53, when the patient's hand is raised upward, the back of the patient's hand contacts the outer wall of the sponge cover 53. When the rotating rollers 52 and the sponge cover 53 rotate, the rotation of the sponge cover 53 can massage the back of the patient's hand.

[0038] A sprocket 54 is fixedly installed at one end of the plurality of rotating rollers 52, and a chain 55 is installed for transmission between the plurality of sprockets 54. By arranging the sprockets 54 and the chains 55, when one rotating roller 52 rotates, one rotating roller 52 can be driven by the plurality of sprockets 54 and the chains 55 to make the plurality of rotating rollers 52 rotate synchronously in the same direction.

[0039] A transmission rod 56 is rotatably installed on the side wall of the placement channel 11, and a bevel gear 57 is fixedly installed on the middle part of the rotating rod 4 and one end of the transmission rod 56. The two bevel gears 57 are meshed with each other, and a transmission wheel 58 is fixedly installed on the other end of the transmission rod 56 and one end of one of the rotating rollers 52. A transmission belt 59 is installed between the two transmission wheels 58. When the rotating rod 4 rotates, the rotating rod 4 can rotate the transmission rod 56 through the two bevel gears 57, and the transmission rod 56 can rotate one of the rotating rollers 52 synchronously through the two transmission wheels 58 and the transmission belt 59.

[0040] Working principle: When the arm of a skin flap or finger replantation needs to be kept warm, the arm is first passed through the annular airbag 12, the patient's arm and hand are in contact with the upper surfaces of the two cushions 33, and then the annular airbag 12 is inflated through the air inlet pipe 13, the annular airbag 12 gradually expands, the patient's arm is stably fixed in the placement channel 11, and the placement channel 11 is sealed at the same time;

[0041] Subsequently, the medical staff fills water into the circular water storage tank 21 through the filling pipe 24, and starts the heater 26. The heating plate of the heater 26 heats the water in the circular water storage tank 21, and the thermal pad 23 conducts the water temperature, so that the inner wall of the warming box 1 is quickly heated up, and the generated high-temperature airflow enters the placement channel 11 through the multiple air inlet slots 27 to keep the patient's arms and hands warm, promote blood circulation, prevent vascular embolism and spasm, and avoid high temperature of the lamp heating, thereby improving the warming effect after flap or severed finger replantation;

[0042] At the same time, the medical staff turns on the motor 39, so that the driving shaft of the motor 39 rotates slowly, and the driving shaft of the motor 39 rotates the rotating rod 4, and the rotating rod 4 rotates the two cams 41, and the two cams 41 make the swing plate 35 move upward through the two arc seats 42, and the swing plate 35 moves with the axis of the rotating shaft 36 as the center of the circle, and the upward movement of the swing plate 35 deforms the torsion spring 37, and the swing plate 35 lifts the patient's hand and arm upward through the lifting plate 32 and a corresponding cushion 33. When the cam 41 is separated from the arc seat 42, the swing plate 35 stops moving upward, and the torsion spring 37 resets the swing plate 35 to move downward and reset, and at this time, the patient's arm and hand synchronously reciprocate up and down, thereby accelerating the blood return of the patient's arm, preventing ischemia and hypoxia at the surgical site, and thereby improving the recovery effect and recovery speed of the flap or severed finger replantation;

[0043] At the same time, the rotating rod 4 rotates the transmission rod 56 through two bevel gears 57, and the transmission rod 56 rotates one of the rotating rollers 52 synchronously through two transmission wheels 58 and a transmission belt 59. One rotating roller 52 is driven by multiple sprockets 54 and chains 55 to make multiple rotating rollers 52 rotate synchronously in the same direction. Multiple rotating rollers 52 make multiple sponge sleeves 53 rotate synchronously in the same direction. When the patient's arms and hands are on the upward stage, the backs of their hands contact the outer walls of the multiple sponge sleeves 53. As the multiple sponge sleeves 53 rotate, the rotation of the multiple sponge sleeves 53 massages the backs of the patient's hands, thereby ensuring the blood circulation of the patient's hands and further improving the recovery effect and recovery speed of skin flap or severed finger replantation.
