Description

Disposable sampling dropper sleeve for cross matching test of blood transfusion department

Technical Field

The utility model relates to the field of cross matching tests, in particular to a disposable sampling dropping pipe sleeve for cross matching tests in a transfusion department.

Background

The cross-matching test includes both a primary test and a secondary test (i.e., primary and secondary side). The former uses blood serum of blood recipient and red blood cell suspension of blood donor to test whether the blood serum of blood recipient contains antibody reacting with red blood cell of blood donor, the latter uses blood serum of blood donor and red blood cell suspension of blood recipient to test whether the blood serum of blood donor contains non-antibody, also called indirect matching. Cross matching is an important basis for determining whether blood transfusion can be carried out, and blood transfusion can be carried out without coagulation on two sides.

The cross matching test method is commonly used in the following two methods:

first, saline medium matching method:

1. two clean small test tubes are taken and respectively marked on the primary side and the secondary side.

2. Blood serum of a blood recipient is added into the main side tube to form two drops and red blood cell suspension of a blood donor is added into the main side tube to form 1 drop respectively. The secondary side tube was added with ﹖ drops of donor serum and 1 drop of recipient red blood cell suspension. Mixing, and centrifuging at 3400 rpm for 15 seconds. The tube was gently shaken and the results observed.

Second, coaguloamine matching:

1. two clean small test tubes are taken and respectively marked on the primary side and the secondary side. A main side tube, 2 drops of patient serum and 1 drop of 3-5% erythrocyte suspension of blood donor; the secondary side tube comprises 1 drop of 3-5% erythrocyte suspension of a patient and 2 drops of blood serum of a blood donor.

2. Respectively adding LIM0.65ml, uniformly mixing, then adding 2 drops of Polybrene solution, uniformly mixing, centrifuging at 3400 rpm for 15 seconds, removing supernatant, slightly shaking the test tube to observe whether agglutination is generated or not, if no agglutination is generated, performing repeated operation, finally adding 2 drops of Resuspending, slightly shaking the test tube to mix and observe the result.

3. If the coagulation is dispersed, the blood matching results are combined, and if the coagulation is not dispersed, the blood matching results are not combined.

Whether any of the above methods is used, there are strict requirements on the sampling of serum, red blood cell suspensions, and even Polybrene solutions, to the point of dripping. However, the currently used sampling dropper is larger than the number of sample drops (such as 1 drop or 2 drops) when sampling, and a tester needs to carefully pinch the rubber cap at the top of the rubber head dropper to drop the liquid with the specified number of sample drops into a small clean test tube. Then, another sample solution is sampled by changing the other test tube, and the liquid with the specified number of sample drops is dripped into the small clean test tube. The whole process not only uses a large number of droppers, but also is difficult to operate and drop the liquid with the specified number of drops into a small clean test tube.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a disposable sampling dropper sleeve for a cross matching test of a transfusion department, which can conveniently control and operate to drip liquid with specified number of sample drops into a small clean test tube, does not pollute the test tube in the whole test process, and can be completed by only using one dropper.

In order to achieve the purpose, the utility model is realized by the following technical scheme:

the disposable sampling and dripping pipe sleeve for the cross matching test of the blood transfusion department comprises a conical medical rubber pipe sleeve with an opening at the bottom, an overflow cavity sleeve is arranged at the lower end of the conical medical rubber pipe sleeve, and an overflow port communicated with the cavity of the rubber pipe sleeve is arranged at the top of the overflow cavity sleeve.

The conical medical rubber pipe sleeve is a pipe sleeve made of transparent materials.

The lower pipe sleeve part of the lower section of the overflow port contains 1 drop of sample liquid.

The lower pipe sleeve part of the lower section of the overflow port contains 2 drops of sample liquid.

An anti-dropping soft rubber ring is arranged on the inner surface of the dropper interface at the top of the conical medical rubber pipe sleeve.

Compared with the prior art, the utility model has the beneficial effects that:

when the medical rubber tube is used, the conical medical rubber tube sleeve is sleeved at the bottom drip opening of the dropper, then the rubber cap at the top of the rubber head dropper is pinched for sampling, and the sucked redundant sample liquid overflows into the overflow cavity sleeve through the overflow opening and is temporarily stored, so that the lower tube sleeve part of the lower section of the overflow opening can accommodate the specified 1-drop sample liquid volume or 2-drop sample liquid volume. Then the specified sample liquid contained in the lower pipe sleeve part at the lower section of the overflow port is dripped into the small clean test tube. The liquid that uses this device can be very convenient control operation to drip the clean little test tube with the liquid of regulation appearance drop number, and sample liquid only contacts the medical rubber pipe box of toper in whole experimentation moreover, can not contact the burette body, can not pollute the test tube, through change the medical rubber pipe box of toper carry on the sample of other sample liquids again can, whole in-process only uses a burette just can accomplish.

Detailed Description

The utility model will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.

Example 1:

the utility model relates to a disposable sampling and dropping pipe sleeve for a cross matching test of a transfusion department, which comprises a main body structure of a conical medical rubber pipe sleeve 1 with an opening at the bottom, wherein an anti-dropping soft rubber ring 5 is arranged on the inner surface of a dropping pipe interface at the top of the conical medical rubber pipe sleeve 1. When in use, the conical medical rubber pipe sleeve 1 is sleeved at the bottom drip opening of the dropper, as shown in the attached figure 4 of the specification, the anti-falling soft rubber ring 5 is extruded and deformed, so that the conical medical rubber pipe sleeve 1 is firmly sleeved at the bottom drip opening of the dropper. In order to facilitate observation of the condition of the internal sample liquid, the conical medical rubber pipe sleeve 1 is a pipe sleeve made of a transparent material.
