Background technique

In order to prevent hypothermia in surgical patients during the operation, and at the same time make the surgeon in a comfortable state during the operation. Since the ambient temperature of the operating room is usually required to be controlled at around 22°C-24°C, patients usually feel cold in the low temperature environment of the operating room. At the same time, the body temperature of the patient will drop under anesthesia, and the rapid convection of the indoor air will increase the heat dissipation of the patient's body. Complications affect the success rate of surgery and are not conducive to the early recovery of patients. Especially in case of hypothermia in critically ill, heavily traumatized, frail surgical patients, there is no corresponding suitable facility to solve it. If the room temperature is forcibly raised during the operation, the surgeon will sweat and itch, making it impossible to continue the operation. The ambient temperature of the operating room is too low for the patient. The prior art utilizes an electric blanket to be laid on the bed surface of the operating bed to increase the body temperature of the patient. This technical solution has the following deficiencies: 1. The electric blanket is difficult to clean and sterilize. Bacteria are easy to reproduce, causing cross-infection, which is not conducive to the work of hospital infection control; 2.

Detailed ways

The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

The operating bed as shown in Figure 1 and Figure 2 comprises a support base 1, a bed board 2 installed on the upper end of the support base 1 and a mattress 3 arranged on the bed board 2, the mattress 3 includes a head section, a back buttock section and In the leg section, a hose 13 in the shape of a double-row involute helix is buried in the back and hip section of the mattress 3, and the hose 13 passes through the water inlet pipe 5 and the return pipe 6 and the heat supply in the equipment room. The devices are connected; the heating device mainly includes a water tank 8, a heater 9 controlled by a temperature controller 15, and a water pump 14. The heater 9 is arranged at the bottom of the water tank 8, and a water supply pipe 8-1 is connected to the top of the water tank 8 to supply water. A replenishment valve 8-2 is installed on the pipe 8-4, and an exhaust valve 8-3 is also arranged on the top of the water tank 8, so that when the pressure in the tank is too large during the heating process, the exhaust valve 8-3 can automatically discharge the water. Air pressure relief. The two ends of flexible pipe 13 pass through from the side of mattress 3, and one end is used as water inlet, and the other end is used as water outlet; Connected to the water tank 8 through the return pipe 6, the water inlet pipe 5, the flexible pipe 13 and the water return pipe 6 are silicone tubes, and the water inlet pipe 5 and the return water pipe 6 are connected to the operating bed from the equipment room through the operating room pendant tower 7; 5 and the connection of the hose 13 and the connection of the return pipe 6 and the hose 13 are equipped with a switch valve 12 with a quick connector, so as to facilitate quick replacement and installation for different operating beds. The water pump 14 is arranged on the water return pipe 6, and the water tank 8, the water inlet pipe 5, the hose 13 and the water return pipe 6 form a heat supply circulation channel. Due to factors such as the temperature in the operating room and the length of the pipeline, some heat will be lost during the delivery of hot water. In order to accurately calculate and control the temperature of the hot water entering the mattress 3, avoid scalding the patient when the water temperature is too high or the water temperature is too low If the unsatisfactory temperature cannot be reached, temperature sensors 8-4, 13-1, 13-2 are provided at the water outlet of the water tank 8, the water inlet and the water outlet of the hose 13; Electromagnetic valve 11 is provided, relay 10 is connected between heater 9 and temperature controller 15, liquid level sensor 16 is set in water tank 8, temperature sensor 8-4, 13-1, 13-2, liquid level sensor 16 , heater 9, solenoid valve 11, relay 10 and water pump 14 are all electrically connected with temperature controller 15. As shown in Figure 3, the outer layer of mattress 3 is leather 3-1, is provided with double-layer sponge pad 3-2 in the mattress 3, and hose 13 is placed between double-layer sponge pad 3-2, can quickly Heat transfer can ensure the comfort of the patient when lying down.

When in use, connect the water inlet pipe 5 and the water return pipe 6 to both ends of the hose 13 of the operating bed with a switch valve 12 with a quick connector, open the valve body to connect the circulation pipeline, and press the corresponding button on the temperature controller 15 to start. The heater 9 heats the water in the water tank 8. When the water temperature reaches the first set value, the temperature sensor 8-4 at the water outlet of the water tank 8 sends a signal to the temperature controller 15, and the temperature controller 15 sends an instruction to start the water pump 14 according to the signal. , and the electromagnetic valve 11 is turned on, the hot water flows into the hose 13 in the mattress 3 through the water inlet pipe 5, and transfers heat to the mattress 3 to supplement the heat for the patient, and the water that has dissipated heat passes through the pump under the action of the water pump 14. The water return pipe 6 flows back into the water tank 8, thereby realizing circulating heating. When the water temperature monitored by the temperature sensor 13-2 at the water outlet of the hose 13 is lower than the second set value, then increase the heating temperature; when the temperature sensor 13-1 at the water inlet of the hose 13 is higher than the third set value , the relay 10 is disconnected to stop the heating, so as to avoid scalding the patient due to excessive temperature. the
