Medical body temperature maintaining mechanism

Abstract

The invention discloses a medical body temperature maintaining mechanism, which comprises a shell provided with an air inlet channel, and another shell provided with a filtering channel, wherein one end of an air inlet of the air inlet channel is provided with a PTC (Positive Temperature Coefficient) heater, the other end of the air inlet is provided with a direct current air pump, one end of thefiltering channel is communicated with the air inlet, the other end of the filtering channel is communicated with the outer world, a filter screen is arranged in the filtering channel, an air outlet is provided with a blast tube, the other end of the blast tube is connected with a protective blanket with a cavity or a semienclosed warm box, an air outlet end of the blast tube is respectively provided with a control valve, a spirally arranged clamp slot used for fixing an infusion tube in the warm box, and a flow control valve for controlling liquid flow in the infusion tube, a plurality of air vents are distributed on the protective blanket, the shell is provided with a control component for adjusting the output power of the PTC heater and the air pump, the warm box and the protective blanket are provided with temperature sensors used for measuring the temperature of air of the protective blanket and the temperature in the warm box, and the temperature sensors, the PTC heater and the air pump are respectively electrically connected with the control component.

Description

technical field [0001] The invention relates to a medical temperature control device, in particular to a medical body temperature maintenance mechanism which maintains the patient's body temperature through a protective blanket and warms the patient's infusion through an incubator. Background technique [0002] With the continuous progress of society, people's living standards are getting higher and higher, and people's requirements for medical equipment and medical environment are also getting higher and higher. However, when patients are exposed to air-conditioned modern operating rooms or wards for a long time during surgery, inadvertent hypothermia is very common, usually resulting in loss of body temperature, although moderate hypothermia can provide certain benefits to the patient's brain tissue in a state of low blood flow. Protective effect, but deeper hypothermia will inhibit the function of vital organs and the metabolism of drugs, and its most profound impact will...

AI Technical Summary

Problems solved by technology

The current main methods include chemical energy heating, electric energy direct heating, water bath heating, microwave heating, etc.: chemical energy heaters cannot be used continuously because they are heated by their own chemical substances, and can only be used in the field and when the amount of infusion is small. ;The water bath heater is safe and has a fast heating speed, which can meet the needs of large flow heating, but the structure is complex and requires specific equipment, and it is generally only used in large operating rooms in large hospitals; microwave heating has the characteristics of fast heating speed, but microwave irradiation Whether it will cause damage to blood and medicinal liquid is rarely used in clinical practice; direct heating with electric energy is cost-effective, easy to use, and a heating method suitable for popular use
