Abstract
The utility model relates to a disposable constant temperature heater for transfusion. A heating element made of the heat sensitive materials of the ceramic semiconductor of a PTC is packed in heat-resistant plastics on which a groove for just sticking a transfusion pipe is arranged. The utility model has the advantages of simple structure, low cost and natural constant temperature. When the utility model is used, the original transfusion apparatus is not changed completely, and use is convenient.
Description
This utility model belongs to disposable medical appliance, particularly a kind of disposable infusion thermostatic heater.
During patient infusion, fluid temperature is low excessively, often causes the discomfort and the clinical transfusion reaction of transfusion patient, brings extra misery to patient.Present existing infusion heating device adopts the whole heating of liquid more, wastes energy; The employing water jacket form that has is used the hot water jacket heating liquid, brings very big inconvenience in operation.
The purpose of this utility model provides a kind of disposable infusion thermostatic heater, overcomes the above-mentioned shortcoming and defect that wastes energy, operates aspects such as inconvenience.
The purpose of this utility model is achieved in that
A kind of disposable infusion thermostatic heater is characterized in that: heater element is encapsulated in the heat resistant plastice, and one groove that just blocks tube for transfusion arranged on the heat resistant plastice, and extracting power supply cord is to the heat resistant plastice outside on the heater element.Groove is the groove of circular arc type.
Heater element adopts PTC ceramic semiconductors thermo-sensitive material to make.
The utility model has the advantages that:
Simple in structure, cost is low, and temperature is constant naturally.During use, original transfusion device is not made any changes, easy to use.
Below in conjunction with description of drawings embodiment:
Fig. 1 is the structural representation of disposable infusion thermostatic heater.
Fig. 2 is the sectional elevation of Fig. 1.
A kind of disposable infusion thermostatic heater, heater element 1 is encapsulated in the heat resistant plastice 2, groove 3 is arranged above the heat resistant plastice one, groove just can block tube for transfusion in groove, extracting power supply cord 4 is to the heat resistant plastice outside on the heater element, and heater element adopts PTC ceramic semiconductors thermo-sensitive material to make.Because the heater element that PTC ceramic semiconductors thermo-sensitive material is made has the nature thermostatic effect, so this heater need not guaranteed the constant of fluid temperature by the temperature-adjusting circuit that temperature sensor and temp-controlling element are formed.
When the temperature of the groove surfaces of this transfusion thermostatic heater was 65 ℃-70 ℃, the effusive fluid temperature of syringe needle for transfusion device can be controlled between 28 ℃-35 ℃.Adjust the transfusion thermostatic heater leaves syringe needle on tube for transfusion distance, fine-tuning syringe needle flows out the temperature of medicinal liquid.
Claims (3)
1, a kind of disposable infusion thermostatic heater, it is characterized in that: heater element is encapsulated in the heat resistant plastice, and one groove that just blocks tube for transfusion arranged on the heat resistant plastice, and extracting power supply cord is to the heat resistant plastice outside on the heater element.
2, disposable infusion thermostatic heater according to claim 1 is characterized in that: the heater element that heater element can adopt PTC ceramic semiconductors thermo-sensitive material to make.
3, disposable infusion thermostatic heater according to claim 1 and 2 is characterized in that: groove is the groove of circular arc.
