Abstract
The cold precipitating preparation instrument includes heat insulating refrigerator, 0-4 deg.c constant temperature control circuit, weight sensing control circuit, display circuit and alarm circuit. The using process includes turning on the power switch to start the heat insulating refrigerator, setting frozen plasma on the weight sensor and transferring bag in the plasma bag groove in the position lower than that of the frozen plasma, and transferring thawed plasma to the transferring bag owing to gravitational force and siphonage. When the residual plasma is reduced to 50 g, the weight sensing circuit and the alarm circuit operate to send out warning signal to show the finish of the cold precipitating preparation process and the relevant information is shown in the LCD. During the whole process, the temperature of plasma is controlled in 0-4 deg.c to ensure the quality and activity of plasma.
Description
Technical field
Blood products when the present invention relates to component blood transfusion in a kind of blood station and the hospital---used instrument when cryoprecipitate prepares.
Background technology
In blood station and hospital's component blood transfusion process, more special a kind of component blood transfusion is the use of cryoprecipitate preparation.This cryoprecipitate is mainly used in hemophilia patient's component blood transfusion.The cryoprecipitate technology is widely used in the blood station at present, for treatment hemophilia patient makes a significant contribution.But the method that is incubated when preparing cryoprecipitate at present all is to reach with ice and frozen water to keep 0 ℃～4 ℃ constant temperature, and this method is not only required great effort but also time-consuming, and the bad control of temperature, and Products Quality also is not easy to guarantee.
Summary of the invention
The purpose of this invention is to provide a kind of advanced technology, cryoprecipitate preparing instrument easy to use.
For achieving the above object, the present invention includes thermal insulation refrigerator, 0 ℃～4 ℃ constant temperature control circuits, weight induction control circuit, display circuit and warning circuits compositions.The loam cake of thermal insulation refrigerator is to be made by transparent heat insulating material, and the plasma bags groove is positioned at thermal insulation refrigerator; 0 ℃～4 ℃ constant temperature control circuits are made up of temperature control induction apparatus and temperature control chip; The weight induction control circuit is made up of weight sensor and weight sensor chip, and weight sensor is positioned at the thermal insulation refrigerator bottom; Display circuit is made up of liquid crystal display and display chip; Warning circuit is made up of buzzer and Music Clip.Refrigerated plasma is placed on the weight sensor in the thermal insulation refrigerator, the blood plasma transfering bag places the plasma bags groove to be lower than the position of refrigerated plasma, because the principle of siphon and gravity, the blood plasma that melts shifts in the blood plasma transfering bag, when the residuals weight in the refrigerated plasma bag is 50g, when promptly cryoprecipitate weight is 50g, weight induction control circuit and warning circuit are started working, send warning, prompting staff cryoprecipitate preparation process is finished, and above-mentioned information is presented on the liquid crystal display by display circuit.In the whole process, 0 ℃～4 ℃ constant temperature control circuits guarantee that blood plasma is in 0 ℃～4 ℃ temperature constant states, guarantee the quality and the activity of each composition in the blood plasma.Adopt said structure, because the present invention adopts 0 ℃～4 ℃ constant temperature control circuits, guarantees that blood plasma is in 0 ℃～4 ℃ temperature constant states, process is finished automatic warning, this has just alleviated blood station and corpsman,hospital's workload greatly, brings great convenience for the component blood transfusion process.
In sum, advantage of the present invention is: advanced technology, alleviate staff's burden greatly, guarantee the quality and the activity of each composition in the blood plasma.
Description of drawings
Below in conjunction with accompanying drawing to further detailed explanation of the present invention.
Figure is a structural representation of the present invention.
7.0 ℃～4 ℃ constant temperature control circuits of 1. thermal insulation refrigerators, 2. switches, 3. plasma bags grooves, 4. weight induction control circuits, 5. weight sensors, 6. power interfaces, 8. temperature control sensors, 9. warning circuits, 10. display circuits, 11. liquid crystal displays among the figure
The specific embodiment
As seen from the figure, the present invention includes 1,0 ℃～4 ℃ constant temperature control circuits 7 of thermal insulation refrigerator, weight induction control circuit 4, display circuit 10 and warning circuit 9 forms.Because the loam cake of thermal insulation refrigerator 1 is to be made by transparent heat insulating material, the plasma bags groove is positioned at thermal insulation refrigerator 1; 0 ℃～4 ℃ constant temperature control circuits 7 are made up of temperature control induction apparatus 8 and temperature control chip; Weight induction control circuit 4 is made up of weight sensor 5 and weight sensor chip, and weight sensor 5 is positioned at thermal insulation refrigerator 1 middle and lower part; Display circuit 10 is made up of liquid crystal display 11 and display chip; Warning circuit 9 is made up of buzzer and Music Clip.At first connect with the mains during use, open switch 2, thermal insulation refrigerator 1 is started working, refrigerated plasma is placed on the weight sensor 5 in the thermal insulation refrigerator 1, transfering bag places plasma bags groove 3 to be lower than the position of refrigerated plasma, because the principle of siphon and gravity, the blood plasma that melts shifts in transfering bag, when residue blood plasma weight is 50g, be cryoprecipitate weight when being 50g, weight induction control circuit 4 and warning circuit 9 are started working, and send warning, prompting staff cryoprecipitate preparation process is finished, and above-mentioned information is presented on the liquid crystal display 11 by display circuit 10.In the whole process, 0 ℃～4 ℃ constant temperature control circuits 4 guarantee that blood plasma is in 0 ℃～4 ℃ temperature constant states, guarantee the quality and the activity of each composition in the blood plasma.
Adopt said structure, because the present invention adopts 0 ℃～4 ℃ constant temperature control circuits, guarantees that blood plasma is in 0 ℃～4 ℃ temperature constant states, process is finished automatic warning, this has just alleviated blood station and corpsman,hospital's workload greatly, brings great convenience for the component blood transfusion process.
