Problems solved by technology

[0008] However, the above-mentioned patented technology or product of the intelligent trimming instrument actually only provides blood bag weighing, weight display and prompt function of blood bag of the same weight, and requires manual addition of trimming objects, and does not really realize the automatic trimming function, and still exists High labor intensity, prone to problems such as human error
[0009] In addition, the existing small objects for counterweights or special weights for silicone rubber are not suitable for filling the gap of the centrifuge liner, which is easy to form a centrifuge dead space and centrifuge breakage of the blood bag, which cannot guarantee the quality and safety of the blood
Moreover, only solid materials are used as the trimming object, the trimming object cannot be too small, and the trimming accuracy is also limited

Abstract

The invention provides an intelligent blood centrifugation balancing instrument and a balancing method. The intelligent blood centrifugation balancing instrument is characterized in that the adopted balancing object comprises plastic cement balancing rods and liquid filler, wherein each of the plastic cement balancing rods is a hollow rod with one end open, and a plug or an elastic closing cover is arranged at the open end. On the basis of the intelligent balancing instrument, a balancing filler chamber is arranged in a case, six feeding tubes independent to each other are connected to a discharging port in the balancing filler chamber, and solenoid valves are arranged on the feeding tubes. A magnetic core push rod of a push electromagnet drives feeding ports of the feeding tubes to move to be in butt joint with the corresponding plastic cement balancing rods in centrifugation lining buckets on trays of electronic balances, the feeding tubes return to the original places after feeding, and the push electromagnet, the solenoid valves and weighing sensors are connected with a board of a single-chip microcomputer. The intelligent blood centrifugation balancing instrument is capable of performing balancing simply, conveniently and accurately and high in automation degree. The balancing object is reasonable in structure and capable of being filled conveniently, formation of centrifugal dead space is prevented effectively, and risk of centrifugal breakage is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an auxiliary equipment for a medical blood centrifuge, in particular to an intelligent blood centrifugal trimmer and a trimming method. Background technique [0002] In order to effectively protect the physiological functions of each blood component, the centrifugation and separation of blood must be carried out in a relatively low temperature (generally 2-6°C) environment. Because the blood bag capacity is generally 200-400ml, a large-capacity low-temperature centrifuge must be used. A large-capacity low-temperature centrifuge is used to separate blood components by gravity centrifugation. The whole blood of the blood donor is collected in a plastic blood collection bag, placed symmetrically in the centrifuge, and different centrifugal forces are selected according to the type of blood components to be separated and prepared (such as: red blood cells, plasma, platelets, e...
