Abstract
This invention discloses a thermostatic apparatus for screening reagent of blood pigments used to keep the reagent of blood pigments in thermostatic status when screening the blood pigments content of person who donates his blood to ensure an accurate contents of blood pigments measured. The invention comprises thermostatic chamber, heating radiator and temperature control device that is composed of temperature sensor, semi-conductor cooling heating unit and temperature control display, which are orderly concatenated. The temperature of the control apparatus is set as 20+/-1 DEG C. This invention is characterized by small volume, low cost, accurate temperature control, simple technique and less technical demands on operating persons.
Description
Technical field
The present invention relates to a kind of constant temperature instrument, be in the constant temperature instrument of 20 ℃ ± 1 ℃ of temperature constant state in particular for keeping the hemochrome screening agent.
Background technology
At present the method that is used for examination blood donation personnel hemochrome content in clinical Blood Transfusion Services mainly is to detect with the hemochrome screening agent, it is the copper-bath hydrometer method, and the temperature of copper-bath must remain on 20 ℃ ± 1 ℃, because the difference of solution temperature changes, the accuracy of testing result there is very big influence.In order to keep the temperature constant state of copper-bath, regulating the room temperature by air-conditioning clinically reaches the purpose of regulating the copper-bath temperature, and like this, the temperature of copper-bath is mutually inaccurate, and affected factor is a lot.And common testing laboratory is adjustable with constant temperature instrument temperature, and volume is big, the cost height, and complicated operation is made troubles to clinical position on the contrary.
Summary of the invention
The purpose of this invention is to provide a kind of temperature precise control, volume is little, and cost is low, the constant temperature instrument that is exclusively used in the hemochrome screening agent simple to operate.
For achieving the above object, the present invention includes thermostatical storehouse, heating radiator and attemperating unit, attemperating unit comprises temperature sensor, temperature control display, control panel and semiconductor refrigerating heating combined equipment, and four are connected in series in proper order, and the desired temperature of control panel is 20 ℃ ± 1 ℃.Temperature sensor is positioned at the side of thermostatical storehouse, can perception air themperature in the thermostatical storehouse, and data are passed to the temperature control display, the temperature control display passes to control panel to data again, regulates temperature in the semiconductor refrigerating heating combined equipment control thermostatical storehouse by control panel.The front of thermostatical storehouse is that transparent material is made, and is convenient to observe situation in the storehouse, but is the lid of switch above, the hemochrome screening agent is put into thermostatical storehouse from above, the four sides constitutes for trilaminate material in addition, and innermost layer is a stainless steel material, the middle layer is a heat-conducting silicone grease, and skin is thick aluminium sheet.The both sides of thermostatical storehouse have two pilot lamp respectively, and described pilot lamp is a cold light source.Described heating radiator is an Aluminium Radiator, and there is vent fan the back of heating radiator, and there is vent port the outside of vent fan.
In sum, advantage of the present invention is: volume is little, and cost is low, the temperature precise control, and operative technique is simple, and is less demanding to operating personnel's theoretical level.

Embodiment
In Fig. 1, the hemochrome screening agent is put into thermostatical storehouse 8, cover thermostatical storehouse lid 12, turn on the power switch 13, temperature sensor 6 detects the air themperature in the thermostatical storehouse 8, and on temperature control display 7, demonstrate temperature value, if the air themperature in the thermostatical storehouse 8 is higher than 20 ℃+1 ℃, refrigerating plant work in the control panel 2 control semiconductor refrigerating heating combined equipments 1, reduce the air work in the thermostatical storehouse 8, when being reduced to 21 ℃, temperature sensor 6 is about to numerical value and passes to temperature control display 7 and control panel 2, and refrigerating plant quits work.When if the temperature in the thermostatical storehouse 8 is lower than 20 ℃-1 ℃, the heating combined equipment work in the control panel 2 control semiconductor refrigerating heating combined equipments 1, the air themperature in the rising thermostatical storehouse 8, when being elevated to 19 ℃, heating combined equipment quits work.So temperature remains on 20 ℃ ± 1 ℃ in the cycle control thermostatical storehouse 8.The front of thermostatical storehouse 8 is that transparent material is made, but is the lid of switch above, and the four sides constitutes for trilaminate material in addition, and innermost layer is a stainless steel material 14, and the middle layer is a heat-conducting silicone grease 15, and skin is thick aluminium sheet 16.The both sides of thermostatical storehouse 8 have two pilot lamp 4 respectively, and pilot lamp 4 is cold light sources, are convenient to observe situation in the storehouse and can influence temperature in the storehouse.Described heating radiator 5 is an Aluminium Radiator, and there is vent fan 3 back of heating radiator 5, and there is vent port 9 outside of vent fan 3.Move for convenience, a handle 11 is arranged above the casing.
