Description
Technical field
The present invention relates to medical auxiliary equipment field, more particularly to a kind of portable infusion using saltcake as insulation material adds
Thermal and its producing principle method.The transfusion heater that the present invention makes can be used for heated at constant temperature transfusion medicament, reduce defeated
Creeping chill and related symptoms that liquid person produces to cryogenic liquid medicament.
Background technology
In cold winter, during patient fluid infusion, cryogenic liquid medicament enters in transfusion person's body, often causes timid cold to transfusion person
Sensation.Especially under prolonged transfusion condition, the position such as arm equitemperature of transfusion is decreased obviously, and transfusion person even produces
Sharp pain.Because infusion fluid and blood of human body temperature difference are larger, it is also possible to trigger the diseases such as vessel retraction, spasm
Shape.Particularly, there is the uncomfortable symptom of low temperature transfusion more universal in old, heart disease, hyperpietic and infant.It is real
The reason in part for infant's resistance transfusion is uttered a stifled cry of agony on border is also too low relevant with transfusion medicament temperature.Therefore, if energy will be defeated
Liquid medicament temperature is brought up to be close with human body temperature, then can significantly reduce sense of discomfort of the patient to low temperature medication infusion.
In the preferable hospital of some medical conditions, equipped with fairly perfect heating or air-conditioning system, patient is to infusing medicine
The uncomfortable problem of the low temperature of agent is not obvious.But in Partial Hospitals, hospital outpatient or Branch Clinic, because condition is relatively simple and crude, lack
Warming environment, the relevant issues that low temperature transfusion band comes seem especially prominent.
At present, the transfusion body heater that China uses, mainly there is two class methods.One class is that infusion bottle is heated, another kind of
It is that woven hose is heated.
Infusion bottle is heated, because amount of liquid is big（Typically at tens milliliters to hundreds of milliliters）, decoction heating rate is slow.And
And, decoction can externally radiate in woven hose transportation, gradually cool down, therefore be still low-temperature condition during into human body, reach
Less than Expected Results.
Woven hose is heated, only several milliliters per minute of the decoction of woven hose is flowed through, heating part can try one's best transfusion
Pin end, closer to human body, therefore heating effect is preferable.Most of existing woven hose mode of heating is heated or electricity using electrical bar
Heated filament is heated, such as Chinese patent CN201420042586.6 and 201320191670.7.Heating wire/electrical bar heating exists a lot
Not enough and shortcoming, one produces electromagnetic radiation when being work, can produce influence to medicament, cause drug molecular structure to change,
Reduce drug effect；Two be that woven hose is directly contacted with the heating wire/electrical bar heated, there is the risk of overheat.The work of many medicines
Property it is closely related with temperature, such as some activated protein medicaments, temperature is too high to cause pharmaceutical activity to be lost.Therefore, it is necessary
Invent the controllable novel infusion heater of a kind of electromagnetic-radiation-free, heating-up temperature.
