Limb trauma low-temperature sterile protection device for emergency department

Abstract

The invention discloses a limb trauma low-temperature sterile protection device for the emergency department. The limb trauma low-temperature sterile protection device is characterized by comprising afirst cover body, a hinge rotating shaft, a second cover body, a latex gasket, an elastic airbag gasket, an ultraviolet disinfection lamp tube, a miniature inflator pump, a semiconductor chilling plate, a small fan and a central control part. According to the device, the semiconductor chilling plate is matched with a temperature controller to create low temperature, the temperature is controllable, and the device is safer to use while low-temperature bacteriostasis is guaranteed. Openings in the head end and the tail end of the device are connected with the latex gasket and the elastic air bag gasket respectively, the elastic air bag gasket can be tightly attached to the skin of a patient after being filled with air, a wound surface located in the device is in a sealed environment, germsare prevented from further invading, and the elastic air bag gasket has elasticity and can adapt to limbs of different thicknesses. The latex gasket plays a role in buffering, and four-limb injury caused by extrusion can be avoided.

Description

technical field [0001] The invention belongs to a wound care protection device, in particular to a low-temperature aseptic protection device for extremity wounds used in an emergency department. Background technique [0002] The emergency department often encounters patients with trauma to the limbs. When the emergency doctor receives the patient and sends the patient to the hospital, the wound is directly exposed to the external environment, and it is very easy to be invaded by germs in the external environment on the wound and cause infection; therefore In this method, doctors generally use low-temperature sterilization protection devices to protect the wounds of limbs; [0003] Most of the currently used hypothermic aseptic protection devices for extremities wounds achieve low temperature by injecting cooling substances, but as the temperature of the cooling substances rises, it will not play the role of creating a low-temperature environment, and the cooling substances n...

AI Technical Summary

Problems solved by technology

[0003] Most of the currently used hypothermic aseptic protection devices for extremities wounds achieve low temperature by injecting cooling substances, but as the temperature of the cooling substances rises, it will not play the role of creating a low-temperature environment, and the cooling substances need to be replaced frequently. Increase the cost of consumables; Another way to achieve low temperature is to use water cooling cycle to create a low temperature environment, but the water cooling cycle method needs to design a liquid storage device on the device, which increases the weight of the entire device, and the cooling effect of the water cooling cycle is very slow and ineffective; Whether using cooling substances or water-cooling methods to create a low-temperature environment, it is impossible to control the low temperature. If the temperature is too low, it may cause frostbite. If the temperature is not enough, there is no low-temperature antibacterial growth effect.
