Manual pressure regulating device of medical sub-hypothermia ice blanket

Abstract

The invention relates to a manual pressure regulating device of a medical sub-hypothermia ice blanket. The ice blanket is connected with a refrigerating system via an ice blanket inlet and outlet tube, a pressure regulator is connected with the ice blanket by a tube, a manual booster pump is arranged on the pressure regulator, and a plug valve is connected to the bottom of the pressure regulator.Pressure of the inside of the ice blanket and refrigerant content can be adjusted at any time during usage according to weights and health conditions of different patients, the contact area between apatient and the ice blanket is maximized, the best contact degree is realized, the body temperature of the patient is reduced faster, and simultaneously, expectant goal can also be achieved rapidly and effectively. During surgery, due to the pressure regulating, the ice blanket cannot be broken even if the pressure is over high during usage, the ice blanket cannot excessively squeeze the body of the patient, so that influence to blood circulation of the patient is avoided, and precious time is gained for timely rescuing and treating the patient. As pressure regulation is realized by the aid of air, the manual pressure regulating device is pollution-free during working and is clean and sanitary. Besides, mechanical electric components are omitted, and accordingly the manual pressure regulating device is simple in structure and high in reliability.

Description

technical field [0001] The invention relates to a medical sub-low temperature ice blanket mattress, in particular to a pressure regulating device for the medical sub-low temperature ice blanket mattress. Background technique [0002] Mild hypothermia therapy refers to the treatment that keeps the patient's body temperature between 30 and 35°C. At present, we often encounter cases of persistent high fever such as traumatic brain injury, joint injury, infection, and coma in clinical practice. Patients with serious conditions need to quickly lower their body temperature to shrink capillaries and reduce local congestion. In addition, cooling can also reduce local bleeding and prevent the spread of inflammation and suppuration, reduce the sensitivity of nerve endings and reduce pain, and buy time for treatment. [0003] At present, most of the cooling accessories in the sub-hypothermia therapeutic apparatus are ice blankets. The principle of cooling is to connect the ice blanket...

AI Technical Summary

Problems solved by technology

However, because the existing ice blankets are generally non-adjustable, that is to say, for a long time, the sub-hypothermia treatment uses the ice blanket to cool down, and the shape of the ice blanket cannot be changed according to different patients so that the ice blanket can reach the best contact with the patient, and the degree of cooling cannot be achieved. Under the control of the operator, the expected goal cannot be achieved

Moreover, during the use of the ice blanket, due to the non-adjustable pressure, it often occurs that the ice blanket is broken due to excessive pressure.
