Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that there is no special equipment for traditional blood transfusion and cross-matching experiments. Common test tubes are used for experiments. The operation is complicated and cumbersome, and it is easy to make mistakes. However, the combiner of the original invention is inconvenient to add intermediate reagents and pump out the test. Clear liquid, not suitable for polybrene medium test, observation of samples, inconvenient operation, etc., providing a multi-purpose disposable blood transfusion cross-matching test combiner

Embodiment 1

[0026] see figure 1 , the present invention has transparent plastic small test tube 5, is provided with a square sampling tube 1 and a circular sampling tube 3 at the upper end of small test tube 5, (two sample loading tubes 1,3 described in the present invention can also One is long and the other is short, or the cross-sectional shapes of the two sample tubes 1 and 3 are designed to be two different other shapes), especially: the upper end of the small test tube is also provided with an agent sampling port 2, and the small test tube 5 The lower part of the bottom is fork-connected with a suction tube 4 at a distance of 4-10mm from the bottom, and is equipped with a sampling observer. It has a suction tube 8, and the tail end of the suction tube 8 is connected with a transparent plastic film bag 7, and the transparent plastic film bag 7 is connected to There is a manual airbag6.

[0027] The length of the suction tube 4 in this embodiment is such that the upper port exceeds t...

Embodiment 2

[0036] see Figure 4-7 , the second structure of the present invention is a group of combiners used for trigeminal-match test, first adopt transparent plastic molding such as Figure 4 As shown in the small test tube 9, the lower part of the small test tube 9 is 4-10 mm (specifically 6 mm) from the bottom surface and a suction tube 10 is cross-connected. The liquid suction tube 10 is arranged upward and is 10-20 mm lower than the upper opening of the small test tube 9 (specifically 15mm for one outlet), take four such small test tubes 9 and connect them into a row (connectors, such as connecting cards, can be used to connect them into one, or they can be made into a row during pre-processing of plastics, and series products can be made according to the needs of the test. Such as 3 in a row, 5 in a row, etc. to apply to various blood matching tests such as dichotomous one, quadruple one, etc.), prepare four rows of small test tubes 9 . Adopt plastic molding a test tube rack 13...

Abstract

The invention relates to medical treatment experiment equipment, and particularly relates to a multifunctional disposable transfusion and cross blood-matching test combiner. The multifunctional is provided with a small transparent plastic test tube, wherein two sample adding tubes are arranged at the upper end of the small test tube. The multifunctional disposable transfusion and cross blood-matching test combiner is characterized in that a reagent adding and sample collecting hole is formed in the upper end of the small test tube, a liquid pumping pipe is crossly connected to a place, which is at a distance 4-10mm from the bottom surface and is provided with a sample collecting observer, of the lower part of the small test tube, the sample collecting observer is provided with a pipette, a transparent plastic film sleeve is connected to the tail end of the pipette, and a manual air bag is connected behind the transparent plastic film sleeve. According to the multifunctional disposable transfusion and cross blood-matching test combiner, the problems that no special tool exists for an existing transfusion and cross blood-matching test, the existing transfusion and cross blood-matching test is very complex and tedious to operate due to the adoption of a common test tube, and is error-prone. The invention provides a multifunctional existing transfusion and cross blood-matching test combiner.

Description

technical field [0001] The invention relates to medical experiment equipment, in particular to a multiple-purpose disposable blood transfusion cross-matching test combiner. Background technique [0002] So far, the blood transfusion departments of hospitals at all levels have done blood transfusion cross-matching experiments based on the principle of safe blood transfusion, applying for blood sources of the same type of ABO blood type and RH blood type (if a type A RH positive patient needs blood transfusion, he must seek A type RH blood transfusion). Positive blood donors), the blood cells and serum of the blood transfusion recipient and the blood recipient are separated, crossed with each other to allow them to react in the test tube, and then observe the hemolysis and agglutination phenomenon to judge whether the blood transfusion can be carried out safely, that is, to conduct a cross-matching experiment. In the prior art, there is no special equipment for blood transfusi...
