Abstract

The utility model relates to a heating and thermal insulation apparatus for infusion, which is composed of a heating layer, an inner liner pad layer and an external thermal insulation layer, wherein, the heating layer is formed by insulation resistance wires winding into long blocks, and a voltage regulation switch is connected in series on a power supply line. The utility model has the functions of heating and thermal insulation to a patient's infusion. The utility model has the advantages of simple structure, low manufacture cost, little power consumption, safe utilization, sanitation and convenience.

Description

Heating and temperature keeping apparatus for infusion

The transfusion heating and heat-insulating device is a kind of medical treatment insulation utensil.

In the winter time, hospital's transfusion room overwhelming majority of China's southern area does not all have heater unit, and at present patient infusion is generally all at room temperature carried out, there is not special-purpose heat tracing facility, transfusion again after the employing preheating that has, but because room temperature is low, the transfusion temperature drops to room temperature very soon, the transfusion of several hrs, and the patient infusion limbs are felt cold, shivering often appears in whole body, has increased misery to transfusion patient.

The purpose of this utility model provides a kind of transfusion heating and heat-insulating device.Simple in structure, low cost of manufacture, power consumption is little, and is safe in utilization, hygienic and convenient.

This transfusion heating and heat-insulating device is made up of electrothermal layer (3) non-conductive fibre yarn (2) (4), heat-insulation layer (5), spacer layer (1), hasp (6), power line (7) and voltage-regulation switch (8).

Now describe its implementation process in conjunction with the accompanying drawings in detail:

Fig. 1 is a Facad structure sketch map of the present utility model.

Fig. 2 is the A-A profile of Fig. 1.

This utility model is insulation resistance wire to be wrapped up in materials such as non-conductive fibre outward, the electrothermal layer (3) of one 220 * 160 millimeters long square of coiled, be pasted on electrothermal layer up and down to improve insulating properties with non-conductive fibre gauze (2) (4), the heating surface of close infusion bottle posts with the good material of conduction of heat makes thin liner (1), the another side of electrothermal layer posts with the heat-insulating property heat-insulation layer (5) made of material preferably, the connection link of electrothermal layer (3) and power supply wiring (7) and voltage-regulation switch (8).The power of electrothermal layer is configured as required, is generally 20-40 watt, and the heat tracing effect can be regulated by by-pass cock.Wherein the voltage-regulation switch is provided with power, cuts out gear, and is provided with power supply indicator.Hasp (6) is sewn on the insulation aspect.

At first this device is fixed on the infusion bottle during use, the plug that plugs in transfers to the prime time position with the voltage-regulation switch, after the transfusion temperature reaches uniform temperature (generally should below 50 ℃), again the voltage-regulation switch be transferred to weak gear, is incubated.Because this device electrothermal layer power is less, when heating, under 0 ℃ of left and right sides room temperature in the prime time position, the transfusion temperature is the highest in the bottle can not surpass 60 ℃, and the voltage-regulation switching line is longer, opens or closes to be regulated by patient oneself, also can regulate, so safe in utilization, hygienic and convenient by caregiver.

Claims

1, a kind of transfusion heating and heat-insulating device is made up of power supply wiring (7) and electrothermal layer (3), it is characterized in that the described electrothermal layer (3) that links to each other with power line (7) wraps up in insulant outward by insulation resistance wire and constituted.

2, a kind of transfusion attemperator as claimed in claim 1 is characterized in that being in series with voltage-regulation switch (8) in the junction of electrothermal layer (3) and power line (7).

3, a kind of transfusion attemperator as claimed in claim 1 or 2 is characterized in that the upper and lower surface of electrothermal layer (3) is pasted with non-conductive fibre gauze (2), (4) respectively.

4, a kind of transfusion attemperator as claimed in claim 1 or 2 is characterized in that posting liner (1) in the outside of non-conductive fibre gauze (2), and heat-insulation layer (5) is posted in the outside of non-conductive fibre gauze (4).
