[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present 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.

[0033] Example 1: Please refer to Figure 1-Figure 10 , an extracorporeal cooling device for emergency department nursing, comprising a main body component 1, both sides of the main body component 1 are fixedly connected with an adjustment component 2, the surfaces of the two adjustment components 2 are slidably connected with a water holding component 3, a replacement component 4 is fixedly connected inside the main body component 1, a spray component 5 is slidably connected to the lower end of the replacement component 4, and the lower end of the replacement component 4 is fixedly connected to a clamping component 6;

[0034] The main component 1 includes a housing 11, and the replacement component 4 includes an A drive gear 42 and a B drive gear 45. The A drive gear 42 and the B drive gear 45 are both rotatably connected to the housing 11, and the two are meshed with each other. The end of the A drive gear 42 is fixedly connected to the A output gear 43. Two A screw rods 49 are rotatably connected to the housing 11. The threads of the two A screw rods 49 are opposite. The end of the A screw rod 49 is fixedly connected to the B output gear 44, and the B output gear 44 is meshed with the A output gear 43. The circumferential surface of the A screw rod 49 is threadedly connected to an external member 48, and the end of the external member 48 is fixedly connected to a replacement plate 47. The upper end of the replacement plate 47 is provided with a sliding groove, and a driving rack 46 is slidably connected in the sliding groove, and the driving rack 46 is meshed with the B drive gear 45.

[0035] The external component 48 includes a threaded portion 481, which is threadedly connected to the surface of the A screw rod 49. The circumferential surface of the threaded portion 481 is slidably connected with a telescopic portion 482, which is fixedly connected to the replacement plate 47. The spray assembly 5 and the clamping assembly 6 are both arranged at the lower end of the replacement plate 47.

[0036] Specifically, when cooling the patient's forehead, the patient can be allowed to lie on the bed first, and the housing 11 can be placed at the head of the bed. The overall height of the housing 11 can be controlled by adjusting the assembly 2, so that one of the replacement plates 47 is located above the patient's head. Then, the A drive gear 42 can be rotated to drive the A output gear 43 to rotate, and the A output gear 43 can drive the two B output gears 44 to rotate, thereby driving the A screw rod 49 to rotate. When in use, since the external component 48 is threadedly arranged on the A screw rod 49, the external component 48 can drive the replacement plate 47 to move left and right, and since the A drive gear 42 and the B drive gear 45 are meshed, when When the A driving gear 42 rotates, it can drive the B driving gear 45 to rotate, and because the B driving gear 45 and the driving rack 46 are meshed, the driving rack 46 can move up and down, and thus can drive the replacement plate 47 to move up and down. When the A driving gear 42 is rotated, one of the replacement plates 47 can be driven to move diagonally downward, while the other replacement plate 47 will move diagonally upward.

[0037] As a further limitation of the replacement component 4 of the present invention, the replacement component 4 also includes an A motor 41, which is fixedly connected to the inner wall of the outer shell 11, and the output end of the A motor 41 passes through the interior of the outer shell 11 and is fixedly connected to the A driving gear 42.

[0038] Specifically, when in use, in order to enable the A driving gear 42 to rotate automatically, an A motor 41 can be set on the housing 11, and the output end of the A motor 41 can be connected to the A driving gear 42, so that the A driving gear 42 can be driven to rotate by starting the A motor 41.

[0039] As a further limitation of the adjustment component 2 of the present invention, the adjustment component 2 includes a fixed plate 21, an A electrically controlled telescopic rod 22 and a support member 23, the fixed plate 21 is fixedly connected to the surface of the housing 11, the A electrically controlled telescopic rod 22 is fixedly connected to the lower end of the fixed plate 21, and the support member 23 is fixedly connected to the telescopic end of the A electrically controlled telescopic rod 22.

A support member 23 is provided at the telescopic end of the A electrically controlled telescopic rod 22, and the support member 23 is placed on the bed. At this time, the extension and retraction of the A electrically controlled telescopic rod 22 can be controlled to control the overall height of the main component 1, thereby making it easier for the patient to lie down or stand up.

[0041] The specific implementation of this embodiment is as follows: when cooling the patient's forehead, the replacement component 4 can be operated so that two cooling towels can be placed on the patient's head respectively, and the two cooling towels are placed alternately on the patient's head, so that the patient's forehead can be cooled by the cooling towels, and after a period of time, when the temperature of the surface of the cooling towel rises, the replacement component 4 is operated in reverse, so that the towel can rise and the other towel can fall, so that the cooling towels can be quickly replaced, thereby reducing the workload of medical staff.

[0042] Example 2: Please refer to Figure 1-Figure 10 The present invention provides a technical solution: the spraying assembly 5 includes a moving block 53, a spraying member 54, a B screw rod 55, an A transmission gear 56 and a B transmission gear 57. A moving groove is opened at the lower end of the replacement plate 47, the B screw rod 55 is rotatably connected in the moving groove, the moving block 53 is threadedly connected to the surface of the B screw rod 55, and the moving block 53 is slidably connected in the moving groove, the A transmission gear 56 is fixedly connected to the end of the B screw rod 55, the B transmission gear 57 is rotatably connected in the moving groove, and the B transmission gear 57 is meshed with the A transmission gear 56, and the spraying member 54 is fixedly connected to the lower end of the moving block 53.

[0043] Specifically, after the cooling towel is used, the surface temperature of the cooling towel is relatively high, and thus the patient's head cannot be cooled. At this time, a movable groove can be opened at the lower end of the replacement plate 47, and a B screw rod 55 is arranged in the movable groove, and an A transmission gear 56 is arranged at the end of the B screw rod 55, and a movable block 53 is threadedly arranged on the surface of the B screw rod 55, and a spraying member 54 is arranged on the movable block 53. The two A transmission gears 56 and the B transmission gear 57 are meshed, and by rotating one B screw rod 55, the other B screw rod 55 can be driven to rotate together, so that the two movable blocks 53 can be moved simultaneously. At this time, alcohol can be sprayed on the surface of the towel below it through the spraying member 54, so that the towel can be disinfected and humidified, which is beneficial to the subsequent cooling operation of the patient.

[0044] As a further limitation of the spray assembly 5 of the present invention, the spray assembly 5 also includes a water tank 51, an inlet pipe 52 and a B motor 58. The water tank 51 is fixedly connected to the surface of the outer shell 11, the inlet pipe 52 is fixedly arranged at the side end of the water tank 51, and the inlet pipe 52 is connected to the inside of the water tank 51, the inlet pipe 52 is connected to the spray part 54, the B motor 58 is fixedly connected to the side end of the replacement plate 47, and the output end of the B motor 58 is fixedly connected to the B screw rod 55.

[0045] Specifically, when in use, a water tank 51 can be set on the shell 11, and the water tank 51 and two spray parts 54 can be connected through the inlet pipe 52. At this time, alcohol can be sprayed on the surface of the towel through the spray part 54, and the B screw rod 55 can be driven to rotate through the B motor 58.

[0046] Furthermore, when in use, a water pump can be provided on the water tank 51, and the water pump can be connected to the spraying member 54. When in use, the alcohol in the water tank 51 can be introduced into the spraying member 54 through the introduction pipe 52 by the water pump, and then the alcohol can be sprayed out through the spraying member 54.

[0047] As a further limitation of the main component 1 of the present invention, the main component 1 also includes a control panel 12, which is fixedly connected to the surface of the shell 11. The shell 11 is configured as a T-shaped structure, and slots are provided at the lower end and both sides of the shell 11.

[0048] Specifically, during use, in order to more conveniently control the operation of the A motor 41 and the B motor 58 as well as the A electric-controlled telescopic rod 22 and the B electric-controlled telescopic rod 33, a control panel 12 can be provided on the housing 11, and the operation of the A motor 41 and the B motor 58 as well as the A electric-controlled telescopic rod 22 and the B electric-controlled telescopic rod 33 can be controlled by the control buttons on the control panel 12. In order to facilitate the replacement plate 47 to move up and down and left and right without being hindered by the housing 11, slots can be provided at the lower end and both sides of the housing 11.

[0049] The specific implementation of this embodiment is: when processing a used towel, the towel can be replaced by the replacement component 4 first, and then the surface of the towel can be sprayed with alcohol by the spray component 5, so that the towel can be disinfected and humidified. By spraying alcohol on the surface of the towel, the cooling effect on the patient can be improved.

[0050] Example 3: Please refer to Figure 1-Figure 10The present invention provides a technical solution: the clamping assembly 6 includes a mounting member 61, a rotating gear A 62, a mechanical claw 63 and a rotating gear B 64, the mounting member 61 is fixedly connected to the lower end of the replacement plate 47, the rotating gear A 62 is rotatably connected to the side end of the mounting member 61, the mechanical claw 63 is fixedly connected to the surface of the rotating gear A 62, the rotating gear B 64 is fixedly connected to the circumferential surface of the screw rod B 55, and the rotating gear B 64 is meshed with the rotating gear A 62.

[0051] Specifically, when handling the towel after use, since the patient's sweat may remain in the towel after use, the B screw rod 55 can be rotated to drive the B rotating gear 64 to rotate. Since the B rotating gear 64 and the A rotating gear 62 are meshed, the A rotating gear 62 will rotate at this time, thereby driving the mechanical claw 63 to rotate together. Since the towel is clamped at both ends by the two mechanical claws 63, the two mechanical claws 63 are reversed, which can drive the two ends of the towel to twist, thereby squeezing out the sweat in the towel.

[0052] Furthermore, the driving principle of the mechanical claw 63 is as follows: the mechanical claw 63 is usually driven by a motor, which provides power to tighten and release the claw. Compared with traditional pneumatic technology, electric drive technology has higher precision and stability. A transmission mechanism is provided inside the claw to convert the rotational motion of the motor into a clamping force to achieve stable clamping of the object. The design of the transmission mechanism ensures the accuracy and reliability of the claw when grasping and releasing the object.

[0053] As a further limitation of the clamping assembly 6 of the present invention, two clamping assemblies 6 are provided, and the two clamping assemblies 6 are both fixedly connected to the lower end of the replacement plate 47 and symmetrically arranged.

[0054] Specifically, when in use, two symmetrical clamping components 6 can be provided to stably clamp the two ends of the towel, thereby facilitating the subsequent placement of the towel more flatly on the patient's forehead and facilitating subsequent operations such as wringing out the towel and spraying alcohol on it.

[0055] As a further limitation of the water holding component 3 of the present invention, the water holding component 3 includes a connecting member 31, an expansion member 32, a B electrically controlled telescopic rod 33 and a guide tube 34, the connecting member 31 is slidably connected to the circumferential surface of the A electrically controlled telescopic rod 22, the expansion member 32 is slidably connected to the inner wall of the connecting member 31, the guide tube 34 is fixedly connected to the lower end of the expansion member 32, and the guide tube 34 is internally connected to the expansion member 32, the B electrically controlled telescopic rod 33 is fixedly connected to the upper end of the support member 23, and the telescopic end of the B electrically controlled telescopic rod 33 is fixedly connected to the connecting member 31; the water holding component 3 also includes an extension gear 35, an extension rack 36 and a mounting plate 37, the mounting plate 37 is fixedly connected to the side end of the connecting member 31, the extension gear 35 is rotatably connected to the surface of the mounting plate 37, an insertion groove is provided at the end of the connecting member 31, the extension rack 36 is slidably connected in the insertion groove, and the end of the extension rack 36 is fixedly connected to the expansion member 32.

[0056] Specifically, during specific use, when squeezing out the sweat remaining in the cooling towel and spraying alcohol on the surface of the towel, in order to prevent sweat and alcohol from dripping directly onto the patient's head, a connecting piece 31 can be slidably set on the A electrically controlled telescopic rod 22, and an extension piece 32 can be slidably set on the connecting piece 31, and an outlet pipe 34 can be set on the extension piece 32, and the outlet pipe 34 is connected to the extension piece 32, and a B electrically controlled telescopic rod 33 is set between the connecting piece 31 and the support piece 23. At this time, the extension of the B electrically controlled telescopic rod 33 can be controlled to control the lifting and lowering of the connecting piece 31, so that the connecting piece 31 can be close to the clamping assembly 6, so that the connecting piece 31 can collect the dripping liquid and then discharge it through the outlet pipe 34 to avoid dripping directly onto the patient's head. In specific use, the extension gear 35 can be driven to rotate, so that the extension rack 36 can be driven to move, thereby pushing the extension piece 32 to move, thereby expanding the water holding capacity.

[0057] The specific implementation of this embodiment is as follows: when processing the used towel, the B screw rod 55 can be rotated to drive the clamping assembly 6 to operate, and then the two ends of the towel can be twisted through the clamping assembly 6 to squeeze out the sweat in the towel, and before squeezing out, the position of the connecting piece 31 can be controlled to collect the squeezed sweat to prevent it from dripping onto the patient's head.
