[0001] The present invention relates to the technical field of emergency treatment of war trauma, and more particularly to an extracorporeal cooling device for war trauma. Background Art

[0002] On the battlefield, when soldiers are injured, inflammation often occurs at the wound site, causing the wound temperature to rise. High temperature will accelerate the deterioration of the wound, prolong the healing time, and increase the risk of infection. Combat trauma treatment is a measure taken to eliminate wound contamination, remove inactive tissue, prevent wound infection, and create good conditions for wound healing through instrument-assisted correction or surgery. When emergency treatment of the injured limbs on the battlefield is performed, in order to avoid secondary injury to the injured limbs due to force, protective gear will be added to the injured limbs. Sponges or gelatin layers are often set inside the protective gear to ensure the comfort of the injured limbs. The sponge and gelatin layer have poor air permeability, which accelerates sweating of the injured limbs, easily breeds bacteria, and is not conducive to later recovery. Therefore, it is very important to effectively cool down combat trauma wounds.

The cooling patch 1 is made of a flexible heat-conducting material, and the shape of the cooling patch 1 can be changed according to the shape of the limbs of different injured persons so that it can be roughly fitted to the limbs for use. The cooling patch 1 has fixed seats 6 on both sides opposite to each other, and a bandage 3 is provided on the fixed seat 6 on one side of the cooling patch 1, and a fastener 5 is provided on the fixed seat 6 on the other side. The cooling device is fixed to the wound by the use of the bandage 3 and the fastener 5 to perform external cooling. A circuitous circulation channel 104 is provided inside the cooling patch 1, which can increase the heat exchange area between the cooling liquid and the cooling patch 1. The two ends of the circulation channel 104 are connected to the outside world at the top of the cooling patch 1 and are respectively a liquid outlet 101 and a liquid injection port 102, and the liquid outlet 101 and the liquid injection port 102 are located below the cooling system 4, which is convenient for connecting with the cooling system 4 to allow the cooling liquid to circulate. The cooling system 4 includes a mounting base 44, which is detachably arranged on one side of the top of the cooling patch 1; a cooling box 41, a micro pump 42 and a power supply 43 are arranged on the top of the mounting base 44, the output end of the micro pump 42 is provided with a return pipe 49 connected to the cooling box 41, the input end of the micro pump 42 is connected to the liquid outlet 101, and the cooling box 41 is provided with a drain port connected to the liquid injection port 102. The drain port is arranged at the bottom of the cooling box 41 and connected to the liquid injection port 102, and the connection between the return pipe 49 and the cooling box 41 is close to the top of the cooling box 41. A box port 410 is arranged on the top of the cooling box 41, which can be used to regularly replace the coolant. The power supply 43 is a rechargeable battery with a fast charging function, and has a long battery life to meet the unstable power supply that may exist in the battlefield environment.

[0023] Cooling liquid that is non-irritating to the skin is stored and circulated in the cooling box 41 and the circulation channel 104. The cooling liquid is initially stored in the cooling box 41. When circulating, the cooling liquid enters the circulation channel 104 from the discharge port at the bottom of the cooling box 41 through the injection port 102. Under the operation of the micro pump 42, the cooling liquid in the circulation channel 104 is returned to the cooling box 41 through the reflux pipe 49.

[0024] A display and control device 45 is also provided on the side of the mounting seat 44. The display and control device 45 includes a display screen, a circuit board and a number of functional control buttons. The micro pump 42 is electrically connected to the circuit board. The top of the mounting seat 44 is provided with a housing 2 that is slid out from one side. A high-precision temperature sensor 46 is provided at the bottom of the display and control device 45. The high-precision temperature sensor 46 is electrically connected to the circuit board. The cooling patch 1 is provided with a mounting port 103, and the high-precision temperature sensor 46 is located in the mounting port 103. The circuit board automatically adjusts the circulation speed and temperature of the coolant through the feedback data of the high-precision temperature sensor 46.

The display screen can display information such as real-time temperature, battery power, and coolant circulation status, so as to timely understand the remaining status of the power supply 43 and prepare for charging in advance. The temperature adjustment range can be adjusted according to the different stages of wound healing, and the measurement accuracy of the temperature sensor is within ±0.5°C. When the cooling device is not needed, the electromagnetic valve 1 48 is closed, and the electromagnetic valve 2 47 can stop the coolant from circulating.

[0025] The four corners of the bottom of the cooling patch 1 are provided with hydrogel adhesive parts that are non-irritating to the skin. The bottom of the cooling patch 1 is provided with an anti-slip patch 7 made of heat-conductive and skin-friendly material, and the anti-slip patch 7 is provided with a positioning hole 72 at the corresponding position of the hydrogel adhesive part. The positioning hole 72 not only facilitates the replacement and positioning of the anti-slip patch 7, but also allows the anti-slip patch 7 to be replaced quickly. The hydrogel adhesive part can pass through the positioning hole 72 to contact the skin so that the cooling patch 1 can be further fixed on the skin of the limbs wound cooling part, thereby enhancing the fixing effect and enabling the cooling to be used without the anti-slip patch 7. While preventing the cooling device from sliding with the limbs, the anti-slip patch 7 can also reduce the contamination of the cooling device by blood stains on the wound, and reduce the infection of the wound by the cooling device.

At the same time, in order to prevent the anti-slip sticker 7 from sliding with the cooling patch 1, the anti-slip sticker 7 has a certain viscosity on the contact surface with the cooling patch 1.

[0027] The bandage 3 is an elastic bandage 3 or a retractable bandage 3, and a lock is provided at the end of the bandage 3 to be buckled with the fastener 5. The bandage 3 is a retractable bandage 3, and a Velcro hook surface and a Velcro velvet surface are provided on the surface of the bandage 3. The end of the bandage 3 passes through the fastener 5 and is fixed by bonding the Velcro hook surface and the Velcro velvet surface. The bandage 3 can be fastened quickly, and can firmly fix the cooling patch 1 on the wound of the limbs, and will not cause excessive pressure on the wound and affect blood circulation.

[0028] Working principle: The in vitro cooling device of the present invention can control the start and stop of the cooling device and other functions through the control button. When in use, the cooling patch 1 and the anti-slip patch 7 are attached to the part of the limbs that need to be cooled. The cooling patch 1 is made of a flexible heat-conductive material, and the shape of the cooling patch 1 can be changed according to the shape of the limbs of different injured persons. The cooling device is fixed by a bandage 3 so that it cannot move between the limbs. Open the electromagnetic valve 1 48 and the electromagnetic valve 2 47. The coolant is initially stored in the cooling box 41. When circulating, it enters the circulation channel 104 from the discharge port at the bottom of the cooling box 41 through the injection port 102. Under the operation of the micro pump 42, the coolant in the circulation channel 104 is returned to the cooling box 41 through the reflux pipe 49. The display screen of the display control device 45 can display information such as real-time temperature, battery power, and coolant circulation status, so as to timely understand the remaining status of the power supply 43 and prepare for charging in advance. The cooling device can automatically adjust the coolant circulation speed and temperature through the feedback data of the high-precision temperature sensor 46.
