Safe cross blood matching card and blood matching method

Abstract

The invention provides a safe cross blood matching card and a blood matching method. The blood matching card comprises a blood receptor plasma containing hole, a blood receptor erythrocyte diluent containing hole, a blood donor plasma containing hole, a blood donor erythrocyte diluent containing hole, a main side cross reaction hole and a secondary side cross reaction hole which are sequentially arranged. Hole number identifiers are arranged below the reaction holes; and information identification areas of blood receptor and blood donors are set. In addition, the blood matching method comprises the following steps: respectively putting blood plasma of a blood receptor and blood plasma of a blood donor into corresponding blood plasma containing holes; putting overstocking erythrocytes of the blood receptor and the blood donor respectively in the corresponding containing holes to prepare erythrocyte suspensions; carrying out sampling on the blood receptor plasma containing hole and the blood donor erythrocyte diluent containing hole and adding the sampled products into the main side cross reaction hole; and carrying out sampling on the blood donor plasma containing hole and the bloodreceptor erythrocyte diluent containing hole and adding the sampled products into the secondary side cross reaction hole to complete cross blood matching. Therefore, Pollution of diluent and waste ofresources are avoided; cross contamination is avoided in a unique person-card-correspondence manner; and the safety of clinical blood transfusion is guaranteed.

Description

technical field [0001] The present invention relates to an experimental device and a blood matching method required for cross-matching blood in clinical laboratories / blood transfusion departments / central blood stations and related scientific research institutes, in particular to a safe cross-matching blood card and a cross-matching method , belonging to the technical field of medical devices. Background technique [0002] Cross-matching blood test before blood transfusion is an important guarantee for blood transfusion safety. The clinical practice has proved that the micro-column gel method is currently recognized as a safe and effective cross-matching method. At present, there are mainly two kinds of microcolumn gel blood matching cards imported in China, Diana from the United States and DiaMed from Switzerland. There are dozens of domestic companies such as Changchun Boxun and Jiangyin Libo. [0003] The operation method, appearance and reaction principle of the above-m...

Problems solved by technology

4. Tear off the film slowly

Opened cell dilutions are often used for weeks or longer, increasing the risk of bacterial contamination that could skew test results

[0017] Second, test tubes and diluents need to be purchased separately to increase costs, and red blood cell suspensions are prepared separately, which increases the number of test operations and increases the possibility of contamination and errors

[0018] Third, since the donor and recipient red blood cell suspensions are prepared in separate test tubes, once the labeling work on the test tubes is forgotten or wrongly marked, it is possible to add the respective red blood cell suspensions of the donor and recipient to their own plasma, resulting in severe error accident

[0019] Fourth, at present, the blood transfusion department of the hospital routinely cross-matches three patients and three blood donors on the same blood matching card, which may lead to errors in adding wrong sample holes; Missplash of liquid from different patients near the test hole leads to wrong test results; it is also possible that the test environment may be contaminated by liquid splash due to crowding

However, the current blood matching card needs to manually write the hospital numbers, departments, bed numbers, and names of the three blood recipients and the blood bag numbers of the three blood donors. , so the traditional three-person blood matching card is not conducive to traceability
