CN2344031Y - Human body fluid infusion heater - Google Patents

Abstract

The utility model relates to a human body fluid infusion heater which is provided with a chamber which is encompassed by a heating body and used for containing a fluid bottle or a fluid bag. The heating body is an interlayer superposition body which is composed of an internal cover layer, a heat conducting layer, an insulating layer, a heating layer, a heat insulation layer and an external cover layer from inside to outside. When the fluid bottle or the fluid bag is put into the chamber and two lead-out terminals of the heating layer are supplied with safety direct current or alternating current voltage, infused fluid or blood products can be heated through heat conduction and the temperature can be raised. If the utility model is provided with a temperature control circuit and the temperature is controlled at an optimum fluid infusion temperature, constant temperature fluid infusion can be realized. Obviously, the utility model can prevent shivering phenomenon of human body in the fluid infusion process.

Description

The human transfusion heater

This utility model relates to a kind of human transfusion heater.

Human transfusion is to point to input medicinal liquid goods or blood products in the vein of human body, because the temperature of medicinal liquid goods and blood products is well below the temperature of human body, tend to occur the phenomenon of shivering when therefore concerning the weakling, infusing, if transfusion speed is fast, shiver phenomenon more very, obviously, this phenomenon of shivering is disadvantageous to sick body.

The purpose of this utility model provides a kind of human transfusion heater that can improve the transfusion liquid temperature.

This human transfusion heater has the chamber that a confession that is formed by the calandria encirclement holds liquid bottle or liquid bag, and this calandria is an interlayer superimpose body, is made up of inner shield layer, heat-conducting layer, insulating barrier, zone of heating, thermal insulation layer and enclosing cover layer from the inside to the outside.

Liquid bottle or liquid bag are put in the chamber of above-mentioned human transfusion device, and add safe direct current or alternating voltage at two leading-out terminals of zone of heating, pass through conduction of heat so, can be heated intensification by defeated medicinal liquid or blood products, if temperature-control circuit is gone up in configuration again, make its heating and temperature control in the best temperature of infusing, then can realize constant-temp transfusion.

Illustrate particular content of the present utility model below in conjunction with drawings and Examples.

Fig. 1: structure diagram of the present utility model;

The vertical view of Fig. 2: Fig. 1.

As shown in the figure, the utlity model has one and surround the chamber 1 that the confession form holds liquid bottle or liquid bag by calandria, this calandria is an interlayer superimpose body, is made up of inner shield layer 2, heat-conducting layer 3, insulating barrier 4, zone of heating 5, thermal insulation layer 7 and enclosing cover layer 8 from the inside to the outside.The material that heats intravital each interlayer is suitably selected, can be made calandria become rigid body, at this moment, the shape of chamber 1 is fixed, also can make calandria become flexible body, and at this moment, the shape of chamber 1 is revocable.Zone of heating 5 generally is power taking heated filament or Electric radiant Heating Film, and insulating barrier 4 generally is to get mica paper, and heat-conducting layer 3 general depletion belong to sheet material or tinsel fabric, and thermal insulation layer 7 is generally got foam plastics or asbestos.Described chamber 1 upper and lower equal opening, upper shed is put into for bottle, bag, and under shed stretches out for tube for transfusion.For inflexible human transfusion heater, chamber 1 also is provided with side opening 9, but so both liquid measures in the direct observation liquid bottle can make the sidewall of the chamber 1 that calandria forms have certain elasticity again, the liquid bottle can be strained at, and improves heat conducting effect.Set up one deck in the outside of zone of heating 5 and tighten up layer 6, make zone of heating 5 be close to insulating barrier 4 and heat-conducting layer 3, also can improve heat-transfer effect.The material that tightens up layer 6 is a rigid material, can be with producing clamping force between the inflexible heat-conducting layer 3 under the effect of radial force.On the basis of said structure, can be further insulating barrier 10 be set tightening up between layer 6 and the thermal insulation layer 7, also control box 11 can be set on enclosing cover layer 8, interior dress temperature-control circuit is by the power input line dc source or the alternating current power supply Access Control box 11 of blood pressure lowering; The control box 11 of also the step-down rectifier DC power supply circuit can being packed into, need only get final product electric main Access Control box 11 this moment, and the temperature-sensing element in the temperature-control circuit then will be arranged on the inwall of chamber 1.

Claims (3)

1, a kind of human transfusion heater, it is characterized in that: have the chamber (1) that a confession that is formed by the calandria encirclement holds liquid bottle or liquid bag, this calandria is an interlayer superimpose body, is made up of inner shield layer (2), heat-conducting layer (3), insulating barrier (4), zone of heating (5), thermal insulation layer (7) and enclosing cover layer (8) from the inside to the outside.

2, human transfusion heater according to claim 1 is characterized in that: the outside of zone of heating (5) is provided with and tightens up layer (6).
