Description

A kind of cold compress that skin does not contact ice cube is brought down a fever device

Technical field

It brings down a fever device the present invention relates to a kind of cold compress, does not more particularly to contact ice cube instead of a kind of skin that ice cube cold compress is brought down a fever Cold compress bring down a fever device.

Background technology

Currently, some symptoms of patient need cold treatment, as patient fever symptoms occurs and body temperature reaches 38.4 DEG C not yet When, although patient does not feel well, but doctor in order to faster search the cause of disease and reduce the drugs such as antipyretic and antibiotic negative work With, generally not give patient medication, crymotherapy is usually taken and brings down a fever.Currently used crymotherapy has：Ice cube cold compress, warm sponge bath, The crymotherapys such as alcohol bath and heat pipe-type physical cooler are brought down a fever, with mitigate the pain of patient and winning find out the cause of disease when Between.Currently used crymotherapy has：

1. ice cube cold compress：After the fabrics such as ice cube towel are wrapped, it is placed in patient's armpit, groin, neck, forehead etc. Place.

2. warm sponge bath：With the armpit for the towel wiping patient for being stained with warm water, groin, neck, forehead etc..

3. alcohol bath：Wiping patient's armpit, groin, neck, forehead etc. repeatedly with the towel for being stained with medicinal alcohol has artery At big blood vessel.

4. using heat pipe-type physical cooler：By heat pipe-type physical cooler, it is placed in patient's armpit, groin, neck etc. Place.Heat dissipation is realized using the cycle of working medium heat absorption evaporation, exothermic condensation in heat pipe.

Although these methods have the cooling effect of bringing down a fever, but also have some unsatisfactory places：

Ice cube cold compress：

Cold patient should not use, because various cold stimulations can all make patient occur shivering, striated muscle heat production increases Add and influences cooling-down effect.Because of reasons such as temperature, hardness and volumes, patient does not feel well, and is unwilling to be clamped and influence cooling Effect.The stringent control of ice cube time needs is clamped, is otherwise susceptible to frostbite skin.Nurse and entourage's workload also compared with Greatly.

Warm sponge bath：

The songe bath whole body time is unsuitable long, and patient is easy to suffer from cold；Water temperature need to be kept in a certain range, and too low patient is not relaxed Clothes overheat and are easy scald, need often to adjust water temperature, increase entourage and obtain workload.It is easy to get clothing, the quilt of patient wet, Patient does not feel well.Slow in reacting and eruption the child that goes into a coma should not use warm sponge bath.

Alcohol puts bath on the skin：

Patient's peripheral blood vessel is shunk after alcohol puts bath cold stimulation on the skin, and capillary pressure increases, and pulmonary vascular resistance is made to increase, Hypoxemia has been aggravated, empsyxis is easy to cause.

Alcohol bath is also not suitable for infant.Because infant's cerebral cortex and corpus straitum develop not perfect, neural marrow Sheath is not formed completely, the body surface face of children is relatively large, skin it is thin it is tender, veins beneath the skin is abundant, after fever at whole body capillary In expansion state, body is low to the tolerance of alcohol, and the ethyl alcohol in alcohol is easy to be absorbed and cause to be poisoned.

Children's measles Rash diease, hemorrhagic tendency, subcutaneous hemorrhage and with it is Cutaneous damage etc. should not use.

Bleeding exacerbation can be directed at after leukemia patient alcohol bath.

The low patient of blood platelet is easy to cause subcutaneous hemorrhage.

Use heat pipe-type physical cooler：

The operation principle of heat pipe-type physical cooler is：Working medium in the body temperature heating, vacuum pipe of patient, working medium is heated to steam It sends out into certain speed and takes the working substance steam for heat.These working substance steams are climbed to condensation segment in pipe, and lead to Crossing the tube wall of condensation segment will be transmitted on radiating fin.The working substance steam for losing heat is condensed into worker quality liquid, these working medium liquid Body under gravity, and flows back into evaporator section along the tube wall of heat pipe, continues the cycle for participating in heat absorption evaporation exothermic condensation, such as This moves in circles, and the heat of patient is brought on radiating fin the air with environment and carries out heat exchange.It is transmitted on cooling fin Heat, heat fin around air；The air heated rises because volume increases due to proportion declines, and the cold air of surrounding is fast Speed adds to the position of ascending air.The reality that moves in circles of the supplement of the rising and cold air of hot-air around radiating fin Distributing for heat on radiating fin is showed.Heat pipe-type physical cooler has heat conduction is fast, patient is not direct to be contacted with various low-temperature receivers The characteristics of, so that heat pipe-type physical cooler is increasingly received an acclaim.But the condensation of working medium all relies on natural convection air, Since the difference of body temperature and environment temperature is less than 15C °, therefore its condensation rate is slower.Although its heat conduction is fast, because its condensation is slow, Therefore the heat absorption for reducing working medium is steamed, the speed of the cycle of exothermic condensation, affects the cooling rate of heat pipe-type physical cooler.Suffer from The body temperature that person, family numbers of patients, doctor and nurse are intended to the patient of fever lowers as soon as possible, therefore heat pipe-type physical cooler Cooling rate must improve, otherwise influence heat pipe-type physical cooler popularization and application.

Invention content

The purpose of the present invention is：Overcome the cooling rate of existing heat pipe-type physical cooler is slow, contacts skin because of ice cube to make Patient does not feel well and is reluctant the shortcoming used, provide a kind of cooling rate it is fast, it is easy to use, be applicable in patient range Extensively, mitigate patient suffering and a kind of both economical skin and do not contact the cold compress of ice cube and bring down a fever device, to replace current extensive ice Block cold compress, alcohol put the cold treatment method such as bath, warm sponge bath and heat pipe-type physical cooler on the skin.To mitigate the pain of patient, to win Valuable Diagnostic Time, early recovery.
