Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a sampler bracket. Background Art

[0002] The blood sampler is one of the most basic means of blood testing. It refers to the sampling and testing of blood samples for analysis and testing to determine the human body's anemia, cholesterol, diabetes, various infections, kidney function, calcium, liver function, blood diseases and physical abnormalities.

[0003] A blood sampler is generally composed of a blood collection needle and a blood collection tube. In the prior art, a vacuum blood collection tube is generally used to collect blood from patients, and a blood collection needle is generally a venous blood collection needle. Both ends of this blood collection needle are puncture needles, one end is used to pierce the tube mouth of the vacuum blood collection tube, and the other end is used to pierce the human skin and blood vessels to collect blood.

[0004] The principle of vacuum blood collection tubes is to pre-evacuate the blood collection tubes with head caps to different vacuum degrees, and use the negative pressure to automatically and quantitatively collect venous blood samples. After one end of the blood collection needle is inserted into the human vein, the other end is inserted into the rubber stopper of the vacuum blood collection tube. Under the action of negative pressure, the human venous blood is drawn into the blood sample container through the blood collection needle inside the vacuum blood collection tube. In one venous puncture, multiple tubes can be collected without leakage. The inner cavity volume connected to the blood collection needle is very small, and the impact on the blood collection volume can be ignored, but the probability of backflow is relatively small. If the inner cavity volume is large, it will consume part of the vacuum degree of the blood collection tube, thereby reducing its collection volume.

[0005] After the blood sampler completes sampling, the blood collection tube is generally placed on a bracket, and then several blood collection tubes and brackets are uniformly sent to the laboratory for testing. The number of holes in the blood collection tube brackets currently used is fixed, such as a Chinese patent (authorization announcement number: CN211514622U), which proposes a blood collection tube bracket for a pediatric intensive care unit. However, sometimes more blood collection tubes need to be stored, and sometimes fewer blood collection tubes need to be stored. Blood collection tube brackets equipped with multiple samplers with different numbers of holes are required, but the number of holes in the patent is not easy to increase or decrease. In order to facilitate personnel to increase the number of holes in the blood collection tube bracket of the blood sampler, we propose a sampler bracket. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a sampler bracket. When it is necessary to increase or decrease the number of holes in the blood collection tube bracket of the blood sampler, the distance between the two groups of support shells can be adjusted by a distance adjustment component. During this process, the first lower horizontal plate will slide along the first support frame, and the first upper horizontal plate will slide along the second support frame. By controlling the number of overlapping holes on the first upper horizontal plate and the second upper horizontal plate, the number of holes can be increased or decreased, thereby solving the background problem.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0025] When it is necessary to increase or decrease the number of holes in the blood collection tube holder of the blood sampler, the distance between the two groups of support shells 1 can be adjusted by the distance adjustment component. During this process, the first lower cross plate 8 will slide along the first support frame 6, and the first upper cross plate 13 will slide along the second support frame 14. By controlling the overlapping number of holes on the first upper cross plate 13 and the second upper cross plate 15, the number of holes can be increased or decreased, thereby realizing the background technology.

[0026] The distance adjustment assembly includes a knob 2, and the front and rear sides of the outer surface of the left support shell 1 are fixedly connected with a screw rod 7, and two groups of internal threaded tubes 5 symmetrically distributed front and back are rotatably installed on the right support shell 1. The screw rod 7 is threadedly penetrated on the corresponding internal threaded tube 5, and the right end of the internal threaded tube 5 is fixedly connected with a worm gear 20. A bidirectional worm 19 is rotatably installed on the right support shell 1, and the bidirectional worm 19 is meshed with the worm gear 20. The knob 2 is fixedly connected to the front end of the bidirectional worm 19.

[0027] When using the distance adjustment component, rotate the knob 2, and the knob 2 drives the bidirectional worm 19 to rotate. Since the bidirectional worm 19 is engaged with the worm wheel 20, it drives the two groups of internal threaded tubes 5 to rotate. Since the internal threaded tubes 5 are threadedly connected with the screw 7, the distance adjustment between the two groups of support shells 1 is achieved.

[0028] A plurality of first fixed strips 10 are fixedly connected to the support shell 1 on the left side, and a plurality of second fixed strips 18 are fixedly connected to the support shell 1 on the right side. Both the first fixed strips 10 and the second fixed strips 18 are provided with a 'T'-shaped groove. The left end surface of the first upper horizontal plate 13 is fixedly connected to the first insertion strip 16, and the right end surface of the second upper horizontal plate 15 is fixedly connected to the second insertion strip 17. The first insertion strip 16 is slidably connected to the 'T'-shaped groove on the first fixed strip 10, and the second insertion strip 17 is slidably connected to the 'T'-shaped groove on the second fixed strip 18.

[0029] When it is necessary to adjust the distance between the first upper horizontal plate 13 and the first lower horizontal plate 8 according to the length of the blood collection tube, the first insertion plate 16 can be slidably inserted into the appropriate first fixed strip 10, and the second insertion strip 17 can be inserted into the appropriate second fixed strip 18, so that the placement height of the bracket can be adjusted to adapt to the length of the blood collection tube, thereby effectively improving the practicality of the bracket.

[0032] The support shell 1 is provided with a handle hole 11, and the handle hole 11 can be conveniently used to carry the support together with the blood collection tube to the laboratory for blood sampling inspection.

[0033] Working principle: When the number of holes in the blood collection tube support of the blood sampler needs to be increased or decreased, the knob 2 is rotated, and the knob 2 drives the bidirectional worm 19 to rotate. Since the bidirectional worm 19 is meshed with the worm wheel 20, the two groups of internal threaded tubes 5 are driven to rotate. Since the internal threaded tubes 5 are threadedly connected with the screw 7, the distance between the two groups of support shells 1 can be adjusted by the distance adjustment component. In this process, the first lower horizontal plate 8 will slide along the first support frame 6, and the first upper horizontal plate 13 will slide along the second support frame 14. By controlling the number of overlapping holes on the first upper horizontal plate 13 and the second upper horizontal plate 15, the increase or decrease of the holes can be achieved;

[0034] When the distance between the first upper horizontal plate 13 and the first lower horizontal plate 8 needs to be adjusted according to the length of the blood collection tube, the first inserting plate 16 can be slidably inserted into the appropriate first fixed strip 10, and the second inserting plate 17 can be inserted into the appropriate second fixed strip 18, so that the placement height of the bracket can be adjusted to adapt to the length of the blood collection tube, effectively improving the practicality of the bracket;
