Abstract
The utility model discloses an electric heater, relating to the electrical heating assembly of a medical infusion thermostat. The electric heater is composed of a support plate (6), a heater (3) arranged on the support plate (6) and a heating tank (1) arranged on the heater (3). The utility model is characterized in that a heat conducting insulation pad (2) is arranged between the heater (3) and the heating tank (1), and the cross section of the heating tank (1) is made into a 'U'-typed 'II'-shaped structure. The utility model has the advantages that the electric heater can be adapted to a plurality of exothermic materials and a plurality of electronic thermostatically control, and heating performance is good. The heating requirement for the constant temperature of medical infusion can be ensured.
Description
This utility model relates to a kind of medical infusion thermostat electric heating assembly.
Electric heater on the medical infusion thermostat is the key component of infusion thermostat, and the quality of its performance directly has influence on the safety of human transfusion.Existing medical infusion thermostat is just because electric heating assembly design reason not to the utmost entirely, and the selection of exothermic material is restricted, and heating properties is not good, occurs easily that overtemperature dissolves tube for transfusion, low temperature does not reach problems such as adding heat request, thereby shape is rung the clinical practice of product.
It is comparatively reasonable that the purpose of this utility model is to disclose a kind of design, can adapt to the control of multiple exothermic material and multiple electronic thermostatic, and heating properties is good, can guarantee the electric heater that the medical infusion heated at constant temperature requires.
Technical solution of the present utility model is: a kind of electric heater by support plate, be located at the heater on the support plate, the heating tank that is located on the heater is formed, its special character is to be provided with the heat conductive insulating pad between said heater and the heating tank, and the cross section of said heating tank is made
Shape or
The shape structure.
Heater in this utility model technical solution adopts heating potsherd or electric heating film or resistance wire.
Felt pad in this utility model technical solution is made by the heat conductive rubber material.
This utility model electric heater is owing to adopted technique scheme, have the advantages that to adapt to multiple exothermic material and the control of multiple electronic thermostatic, can avoid overtemperature to dissolve the situation that tube for transfusion, low temperature do not reach heating-up temperature and take place, can guarantee the homothermic heat request that adds of medical infusion.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a left pseudosection of the present utility model.
Fig. 3 is an A-A profile of the present utility model.
Fig. 4 is a B-B profile of the present utility model.
Embodiment of the present utility model is as shown in drawings: by support plate [6] be located at heater [3] on the support plate [6], be located at the heat conductive insulating pad [2] on the heater [3], the heating tank [1] that is located on the felt pad [2] is formed.Its cross section of heating tank [1] is made
Shape or
The shape structure, here owing to supporting with the tube for transfusion of 4.5mm, thus make length 17mm, width 12mm, groove width is 4mm deeply, and bottom land is a semicircle shape.It is 150～250mm that heating tank [1] generally adopts length, and frid is wide to be 12～25mm, and groove width is 3～6mm, and groove depth is 3～8mm.Material is an aluminium section bar, also can adopt copper or the good material of other heat conductivity.Felt pad [2] adopts the insulant of heat conductive rubber or other good heat conductivity, and its length and width and heating tank are suitable.Heater [3] adopts 4 (also can adopt 3 chips more than 5) PTC potsherd that generates heat, and is provided with along the support plate length direction.Because the heating tank bottom is the plane, heater also can adopt (TOC) electric heating film or resistance wire, the top and bottom of heater [3] are provided with electrode [4], and support plate [6] adopts epoxy offset plate or other partiting thermal insulation material, and support plate [6], felt pad [2], heating tank [1] connect with screw [5].The electric heater of present embodiment, through thousands of different temperatures, different transfusion constant temperature experiment of dripping speed, better performances overtemperature do not occur or does not reach the phenomenon of heating-up temperature, can reach the requirement of peace property entirely of medical infusion constant temperature fully.
