Description

Portable liquid heating therapeutic instrument

Technical Field

The patent of the utility model relates to the field of medical equipment, especially a portable liquid therapeutic instrument that heats.

Background

After general anesthesia, the patient has a relatively obvious hypothermia, and the core body temperature is usually reduced by 1-3 ℃. Postoperative body temperature recovery usually takes 2-5 hours or more. With respect to the incidence of hypothermia during the operative period, a cross-sectional survey in a part of the country in 2017 reported data of 44.5%. Mild hypothermia at 34-36 ℃ can cause an adverse stimulus to a human body, cause a series of stress reactions and bring about a plurality of adverse outcomes, such as: the incidence of cardiovascular adverse events increased by 4.9%, surgical infection rate increased by 13%, coagulation/fibrinolysis dysfunction, shivering, prolonged awakening, etc.

There are two common heat preservation methods: passive insulation and active insulation. Passive heat preservation measures such as covering cotton blankets, surgical drapes and the like can reduce 30% of heat loss, but are not enough to prevent the body temperature of the patient from lowering after anesthesia, so active heat preservation measures still need to be implemented; the active heat preservation measures mainly comprise a pressure warm air blanket and infusion heating equipment. Research shows that in non-extracorporeal circulation coronary bypass operation, the temperature reduction during operation can be effectively prevented by inputting warming liquid.

2017 edition "perioperative hypothermia prevention and treatment expert consensus" recommendation: infusion of more than 500ml of fluid and refrigerated blood products requires infusion by warming to 37℃ using an infusion warmer, and all peritoneal irrigation solutions are recommended to be warmed to 38-40℃ before use, thus fluid warming is essential.

The currently used liquid heating methods mainly include:

1) heating in water bath: the liquid bottle is placed in a thermostat or a microwave oven for heating, then the infusion tube is placed in the heated liquid bottle, and the infusion tube heats the blood transfusion and the infusion through heat conduction in the process of flowing through the hot liquid bottle. The disadvantages are mainly: has potential safety hazard, uncertain temperature, troublesome use, and can cause hemolytic reaction of blood products due to overhigh temperature, and can not be safely used for heating refrigerated blood products.

2) Heating in a constant temperature box: the liquid to be infused is placed in a constant temperature cabinet to be heated to 37 ℃, and then is infused into the body of a patient, and is mainly used for heating medical saline, blood products, flushing fluid, peritoneal dialysis solution, B-ultrasonic liquid and traditional Chinese medicine decoction and keeping the constant temperature of auxiliary medicines in an operating room. The disadvantages of the method are that the heating speed is slow, at least 30min is needed, and the liquid temperature can drop rapidly in the room temperature environment, so that the liquid can not be infused into the body of a patient at constant temperature.

3) Blood transfusion and infusion heating instrument: the device is used for heating liquid in the processes of blood transfusion, fluid infusion and nutrient solution infusion, the heating process is controlled by a microcomputer, the temperature is accurately adjusted, and the whole process is constant. The device has the disadvantages of high manufacturing cost, large volume and inflexible use, and cannot be popularized and applied to each patient in a large area.

In conclusion, the existing water bath heating and thermostat heating both belong to the traditional heating mode, and have the disadvantages that the temperature of the liquid medicine is suddenly high and suddenly low, the control is not suitable, and the use is inconvenient; the existing transfusion and blood transfusion heating instrument is an instrument with relatively large volume, and has the defects of inconvenient use, high cost and difficult realization of large-area popularization and generalization.

Based on this, how to achieve portable warming of liquids is a technical problem that those skilled in the art need to solve at present.
