Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical equipment, especially relates to a test tube observation auxiliary assembly for protein qualitative test. BACKGROUND

[0002] Protein qualitative test is an experimental method for detecting whether protein exists in a sample. This test is usually based on the chemical reaction between protein and specific reagents, and whether the sample contains protein is judged by observing the formation of white turbidity or precipitate.

[0003] For example, for cerebrospinal fluid, thoracic and abdominal fluid, urine and other body fluid samples, observing the formation of white precipitate is a key step to determine the test result. However, in actual operation, the formation of white precipitate is sometimes not obvious, only showing a small amount of white cloud, making observation very difficult, and specific environmental conditions need to be used to assist identification. At present, the commonly used method is to use black paperboard as background to enhance contrast. However, the black paperboard limits the angle and position of observation. In order to obtain the best observation effect, the tester needs to constantly adjust the position and angle of the paperboard to ensure that the white precipitate can be clearly seen. Sometimes after observation, the test tube is put back into the test tube rack, and after a period of time, it needs to be taken again and placed on the back with black paperboard to observe the reaction again to review or confirm again. Therefore, this step faces many inconveniences. SUMMARY

[0004] In view of the above problems, the purpose of the utility model is to provide a test tube observation auxiliary assembly for protein qualitative test, which aims to solve the above technical problems.

[0005] The utility model adopts the following technical scheme:

[0015] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following is with the drawings and embodiment, and the utility model is further detailedly explained.It should be understood that the specific embodiment described here is only used to explain the utility model, and is not used to limit the utility model.

[0016] In order to explain the technical scheme described in the utility model, the following is explained by specific embodiment.

[0017] As Figures 1-3 shown, the test tube observation auxiliary assembly of protein qualitative test provided by the embodiment includes the black sleeve 1 of cylindrical, the front of black sleeve 1 is provided with open 2 from approaching bottom position upwards, the back of black sleeve 1 has a pair of protruding strip as pressing part 3, the bottom position of the front of black sleeve 1 is provided with slot 4, and the bottom end of black sleeve 1 and located the outside of protruding strip is provided with support part 5.

[0018] In the structure, the black sleeve clamp is made of plastic material. When the protruding strips are pressed, the part of the black sleeve clamp between the protruding strips can be deformed to a certain extent, so that the black sleeve clamp is opened to a certain extent. When operating, the protruding strips on the back of the black sleeve clamp are pressed first. After the black sleeve clamp is opened to a certain extent, the test tube is inserted from the top down until the lowest position, and then the protruding strips are released. The black sleeve clamp is reset to clamp the test tube. The embodiment is not limited to a specific use. The detection liquid of the protein qualitative test can be added to the test tube first, then the reaction reagent is added, and the top cover is covered. Finally, the test tube is inserted into the black sleeve clamp. Alternatively, the test tube with the detection liquid can be inserted into the black sleeve clamp first, then the top cover is opened to add the reaction reagent, and finally the top cover is covered.

[0019] Since the front of the black sleeve clamp is open, the internal reaction of the test tube can be observed from the front. The black sleeve clamp serves as a reference background, so there is no need to use black paper as a background. Therefore, the operation of this method is simpler. In another way, the test tube and the black sleeve clamp can also be placed directly on the desktop without the need for the tester to pick up and observe and place the operation, further improving the convenience of the operation.

[0020] It should be noted that the embodiment is also not limited to the specific height position of the test tube in the black sleeve clamp. The test tube can be inserted directly to the lowest position, or the height of the test tube can be adjusted so that the sample in the test tube is in the best observation position.

[0021] In addition, a notch 4 is formed at the bottom of the front of the black sleeve clamp 1. The width of the notch 4 is smaller than the opening 2. The purpose is to increase the area of the bottom of the black sleeve clamp, and the black sleeve clamp is more stable when placed on the desktop. Further, a support part 5 is provided at the bottom end of the black sleeve clamp 1 and outside the protruding strip, that is, a circle of support parts is also provided at the bottom of the black sleeve clamp (there are no support parts at the positions between the protruding strips and below the notch). The purpose is to further increase the contact area with the desktop without affecting the pressing operation. The protruding strip is arranged along the height direction of the black sleeve clamp and consistent with the height of the black sleeve clamp. The bottom of the protruding strip can also be used as a support, and the structure is also more beautiful.

[0022] As shown in Figure 4 Since the height of some models of test tubes is different, in order to form a long enough black background on the back of the test tube, the test tube observation auxiliary assembly also includes an extension sleeve clamp 6, and the transverse cross-sectional shape of the extension sleeve clamp is consistent with the transverse cross-sectional shape of the upper part of the black sleeve clamp. The front of the extension sleeve clamp also has an opening, and the back also has a pair of protruding strips. The extension sleeve clamp can be clamped on the neck of the test tube first, then the test tube is inserted into the black sleeve clamp, and finally the position of the extension sleeve clamp is adjusted to contact the black sleeve clamp, which becomes a whole black background reference, and is more suitable.

[0023] In addition, as a preferred structure, the bottom of the protruding strip of the extension sleeve 6 is fixed with a steel rod 7, the top of the protruding strip of the black sleeve 1 is provided with a matching hole 8, and the steel rod 7 is inserted into the corresponding matching hole 8. For another use mode of the extension sleeve, the extension sleeve can be connected with the black sleeve integrally through plug-in placement, the overall opening of the black sleeve and the extension sleeve can be realized by operating the protruding strip of the black sleeve, and the operation mode is simplified.

[0024] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
