Abstract
The utility model relates to a device for defrosting frozen blood plasma, which is suitable for hospital blood bands or central blood stations. The device for defrosting frozen blood plasma is composed of a control box, a defrosting groove, a heating box, etc. The internal part of the heating box is provided with an electric heater, and a pipeline device of water circulation is arranged between the heating box and the defrosting groove. The defrosting box adopts a microcomputer to control the whole working process, and the device for defrosting frozen blood plasma has functions of temperature display, temperature alarm, upper water drainage, etc. In order to prevent breakage of the blood bag and cross contamination caused by the breakage or leakage of the blood bag, the internal part of the defrosting groove is provided with cellular defrosting clamps. When the utility model melts the blood plasma, no ' hot ' points can be generated; effective ingredients of the blood plasma can not be broken, and the device for defrosting frozen blood plasma is very safe for red blood cells.
Description
This utility model relates to a kind of equipment that is used for the quick-thawing refrigerated plasma that is applicable to hospital blood bank or blood station, center.
Along with blood component blood transfusion extensively the carrying out of China, the clinical usage ratio of refrigerated plasma has accounted for 15%～40% of whole blood component blood transfusion.These product are generally in-20 ℃ of preservations, and must place 34 ℃～37 ℃ temperature to make its thawing in use rapidly.At present, domestic clinical hospital blood bank or blood station, center are adopted the light water incubator mostly, refrigerated plasma is put into this water tank after, constantly rock by hand and thaw.Because this equipment water temperature is irregular, causes refrigerated plasma thawing speed inconsistent, thereby influence the quality of blood plasma components; Also may cause the pollution of blood plasma simultaneously because of the plasma bags seepage.
The purpose of this utility model provides a kind of blood plasma that can make and melts and make the quick-thawing equipment that the blood plasma effective ingredient is not destroyed fully fast.
The refrigerated plasma that the utility model proposes case that thaws, it is made up of electric heater unit, thawing vat and control chamber etc., and the heating cabinet and the thawing vat branch that are provided with electric heater are arranged, and are provided with the water circulation pipe device between heating cabinet and thawing vat.When thawing, the refrigerated plasma bag is placed in the thawing vat, water is heated to design temperature in heating cabinet, is recycled pump then and sends into thawing vat by water circulation pipe, and after carrying out heat exchange with the refrigerated plasma bag, the water recirculation enters the heating cabinet internal heating.The circulation current have been accelerated the heat exchange of refrigerated plasma and water, and refrigerated plasma is melted quickly and safely to the temperature that is fit to human body.
Because the structure and the soft water circulation system of this utility model that have adopted above-mentioned heating cabinet and thawing vat branch to be arranged are fully melted blood plasma, no high spot does not destroy the blood plasma effective ingredient, and is as safe as a house to erythrocyte.
(embodiment) is further described the technical solution of the utility model below in conjunction with accompanying drawing.
Accompanying drawing discloses the micro-processor controlled case that thaws of a kind of employing.Fig. 1 is a structural representation of the present utility model.Number in the figure is represented respectively: 1. control chamber; 2. folder thaws; 3. thawing vat; 4. electric heater; 5. heating cabinet; 6. water circulation pipe device; 7. go up drainage arrangement; 8. level sensor; 9. temperature sensor.Fig. 2 is an operation principle block diagram of the present utility model.
This utility model is made up of control chamber, thawing vat, heating cabinet etc., is provided with electric heater in the heating cabinet, is provided with the water circulation pipe device between heating cabinet and thawing vat.The case that thaws adopts microcomputer to control its entire work process, and has functions (referring to Fig. 2) such as temperature demonstration, overtemperature alarm and last draining.Cross-contamination damaged and that cause because of the breakage of blood bag or seepage is provided with the basket that thaws of lattice, and can uses special-purpose bag that plasma bags and water are completely cut off in thawing vat for anti-hemostasis bag.This utility model can be set thaw point and thawing time, temperature-controlled precision height according to user's requirement.The thaw refrigerated plasma bag of 200ml～1200ml only needs 8～18 minutes.
