During medical rescue, the injured often die from excessive blood loss due to failure to receive blood transfusions in time in the wild. The main reason for this situation is the lack of relevant instruments and equipment that can adapt to the outdoor environment. The existing blood recovery or blood transfusion equipment is large in size and can only be used in hospital operating rooms. Medical staff usually need to transport the injured with severe bleeding to an ambulance or operating room before they can perform a blood transfusion on the injured. There is a possibility that treatment will be delayed due to the lack of blood recovery or blood transfusion equipment, affecting the probability of successful treatment of the injured. Therefore, there is an urgent need to develop portable blood collection, filtration, storage and transfusion medical equipment for rescuing the injured. Summary of the invention

[0035] In a preferred implementation manner of this embodiment, a cover body 212 is rotatably provided on the side wall in the height direction of the device housing 21. When the cover body 212 is in contact with the side wall in the height direction of the device housing 21, the cover body 212 can cover the openings of the plurality of mounting grooves 211, thereby reducing the possibility of the blood inlet channel 12 and the blood transfusion channel 13 placed in the mounting groove 211 falling off due to external shaking, so that the blood inlet channel 12 and the blood transfusion channel 13 can maintain a state of being in contact with the ultraviolet lamp 241, thereby achieving a better sterilization effect on the blood passing through the blood inlet channel 12 or the blood transfusion channel 13.

[0036] refer to Figure 5The driving assembly 23 includes a peristaltic pump, which includes a mounting box 231, a roller 232, a driver 233 and a hose 234. The mounting box 231 is provided with a mounting cavity 2311, the roller 232 is movably arranged in the mounting cavity 2311, and the roller 232 can rotate circumferentially around its own axis. The driver 233 is used to drive the roller 232 to rotate clockwise and / or counterclockwise, and the driver 233 is connected to the main control unit 22 for communication; the hose 234 is arranged between the side wall of the outer edge of the roller 232 and the inner wall of the mounting cavity 2311, and the hose 234 is arranged around part of the outer edge of the roller 232. The roller 232 can squeeze the hose 234 when it rotates; both ends of the hose 234 in the length direction are penetrated through the installation box 231 and extend to the outside of the installation box 231, one end of the hose 234 in the length direction is connected to the blood storage bag 11, and the other end is connected to the blood inlet channel 12 and the blood transfusion channel 13; in this embodiment, a three-way tube 235 is provided at the end of the hose 234 away from the blood storage bag 11, a first port of the three-way tube 235 is connected to the hose 234, a second port of the three-way tube 235 is connected to the blood inlet channel 12, and a third port of the three-way tube 235 is connected to the blood transfusion channel 13.

[0037] The roller 232 squeezes the hose 234 when rotating. In the squeezed area, the cross-section of the hose 234 becomes smaller and closed, forming a "pillow" shaped fluid. As the roller 232 continues to rotate, negative pressure is formed in the hose 234, and the fluid in the previously squeezed area begins to move in the direction of discharge, so as to drive the liquid in the hose 234 to move in the specified direction. In this embodiment, the hose 234 is made of wear-resistant and corrosion-resistant materials, such as rubber, silicone or polyurethane, so as to extend the service life of the drive component 23.

[0038] In this embodiment, the driver 233 adopts a servo motor. The control accuracy of the servo motor is high and the positioning accuracy is very accurate. When the signal voltage is zero, there is no self-rotation phenomenon, thereby reducing the possibility of the blood flow direction in the hose 234 changing due to the self-rotation of the driver 233; the base of the servo motor is fixedly connected to the outer wall of the installation box 231, and the output end of the servo motor is passed through the installation box 231 and extends to the inside of the installation cavity 2311, and the output end of the servo motor is coaxially fixed with the mixing wheel; the main control unit 22 can control the servo motor to rotate forward or reverse, thereby controlling the blood flow direction or outflow of the blood storage bag 11.

In this embodiment, the rotation speed of the servo motor is adjusted by the regulating module 236 to adjust the blood flow through the hose 234 per unit time. Medical staff can adjust the blood recovery or infusion speed through the regulating module 236.

[0040] Specifically, the adjustment module 236 can receive the running speed information; after receiving the running speed information, the adjustment module 236 generates a speed adjustment instruction based on the running speed information and sends it to the driver 233 to control the running speed of the driver 233; The adjustment module 236 can obtain the running speed information through an input unit, such as receiving the running speed information through a knob, a keyboard input, a touch screen input, or an audio input; the interface can also obtain the running speed information through a communication unit, such as through a wired communication form such as a control line, or by receiving the running speed information through a wireless signal; In one embodiment of the present application, the method for obtaining the running speed information is preferably a knob.

When the gas in the hose 234 is greater than a preset threshold range, the gas ultrasonic detection device 28 issues a warning instruction, and the driver 233 is closed after receiving the warning instruction, and blood transfusion into the patient's body is stopped, thereby reducing the possibility of gas transfusion into the injured person and improving the safety of the blood transfusion system during use.

[0042] refer to Figure 2 The gas ultrasonic detection device 28 is communicatively connected to an early warning component 29, and the early warning component 29 can issue a prompt message; after receiving the early warning instruction, the early warning component 29 issues an alarm to prompt the medical staff to deal with it in time. In this embodiment, the early warning component 29 can be an audible and visual alarm, or a voice prompter, a buzzer or an indicator light, or other devices that can issue an alarm message. This embodiment is not limited, and it is sufficient to be able to prompt the medical staff.

[0043] refer to Figure 1 and Figure 7 A accommodating chamber 213 for accommodating the blood storage bag 11 is provided inside the equipment housing 21. The opening of the accommodating chamber 213 is covered with a side door 214, which is rotatably connected to the side wall of the accommodating groove. The side door 214 can reciprocate toward or away from the opening of the accommodating chamber 213 to facilitate medical staff to take and place the blood storage bag 11.

[0044] When in use, the side door 214 is opened to place the blood storage bag 11 in the accommodating chamber 213, and then the side door 214 is closed, so that the blood storage bag 11 will not be exposed to the outside of the device housing 21, thereby protecting the blood storage bag 11 and reducing the possibility of blood spillage due to external collision and squeezing of the blood storage bag 11; a hook 215 is protruding from the side wall of the accommodating groove away from the opening, and the blood storage bag 11 can be hung on the hook 215 when in use, thereby improving the stability of the blood storage bag 11.

[0047] The use of the heat conducting plate 251 can reduce the possibility of direct contact between the blood storage bag 11 and the heating plate 252. The heat conducting plate 251 can heat the pot more evenly, thereby reducing the possibility that the blood storage bag 11 may be affected in its blood state due to excessively high local temperature.
