Abstract
A heater for regulating the temp of fluid, especially the intravenous perfusion, is composed of an electrically conductive metal element, a heating PTC element, an electric conducting line, a potentiometer, and a casing with clamp, line inlet, knob of potentiometer and indicating lamps. Its application is also disclosed.
Description
Technical field
The present invention relates to a kind of fluid homoiothermic heater, be particularly useful for the heating homoiothermic usefulness of hospital's medium-sized vein transfusion, also can be used for the ducted fluid homoiothermic heating of other miniature fluids and use.
Background technology
Fluid in the small pipeline is generally refused homoiothermic, but during the transfusion of hospital medium-sized vein, because the raising of people's living standard, when winter, temperature was low in addition, the medicine stream of input was because of close with room temperature, with the body temperature of human body difference to some extent, to the patient uncomfortable feeling is arranged, what have has a pain.The heating of useful hot water bag or hot towel, but wayward temperature, can Yin Wendu too high and cause that medicine decomposes, make to lessen the curative effect or cause other side effect.Also have and use electric heater unit, its heater element, parallel arranged, the thermal efficiency is low.On-off control can only have a grade homoiothermic.。
Summary of the invention
The object of the present invention is to provide a kind of simple and reasonable, thermal efficiency height, the fluid temperature regulating heater of stepless temperature-regulating.
Technical scheme of the present invention is, a kind of fluid temperature regulating heater, has the metal heat-conducting element, the PTC heater element, lead and shell, shell comprise lid and box body, and metal heat-conducting element and PTC heater element axially spaced-apart are arranged and combined closely, the heating groove is all arranged and respectively heat groove axially to connect, the PTC heating element heater is clipped between the metal heat-conducting element; Adjacent metal heat conducting element one joint is by lead, and another joint is connected with power input by lead and potentiometer; The periphery of metal heat-conducting element and PTC heater element is coated with insulation material, and insulation material places in the shell.
Metal heat-conducting element and PLC heater element are the column of band heating groove, and the axial columns body length of order metal heat-conducting element is preferably greater than column diameter radially, and the axial columns body length of PTC heater element is preferably less than column diameter radially.
For preventing that heater tube leakage influence from causing electric leakage to be preferably in heating groove inwall and being coated with insulating barrier.
For PTC heater element and metal heat-conducting element are combined closely, there is depression the end of metal heat-conducting element, and bonding by conducting resinl between metal heat-conducting element and the PLC heater element.
Potentiometer be to be installed, can the metal heat-conducting element wherein be provided with the potentiometer installed surface on one, on this installed surface potentiometer is installed.
Preferably the shell two ends have end cap, and the observation window of printing opacity is housed on the lid.
Preferably shell is provided with clip, incoming line, potentiometer knob hole and display lamp.
The present invention is simple and reasonable, and heat energy utilization rate height, but stepless temperature-regulating can be not supercool or overheated, aesthetic in appearance, safe and reliable, easy to use.
