Description

Technical Field

[0001] The utility model relates to the technical field of test samplers, in particular to a sampler for medical testing. Background Art

[0002] Medical testing is a discipline that conducts microbiology, immunology, biochemistry, genetics, hematology, biophysics, cytology and other tests on materials taken from the human body, thereby providing information for the prevention, diagnosis, treatment of human diseases and the assessment of human health. During the medical testing process, a medical test sampler is required to sample the test fluid.

[0003] The Chinese patent application number 201922136811.5 proposes a sampler for medical examination, including a tube body with an open upper end, a piston plate slidably connected to the tube body, a sliding rod fixedly connected to the upper side of the piston plate, an inlet and outlet pipe provided at the lower end of the tube body, a needle mounted on the inlet and outlet pipe, a protective sleeve provided at the lower end of the tube body, a clearance hole provided at the lower end of the protective sleeve, and the needle can pass through the clearance hole. The sampler for medical examination provided by the utility model is provided with a protective sleeve at the lower end of the tube body, which can protect the needle to prevent it from breaking during movement, and the protective sleeve can be clamped in the annular groove during sampling without affecting sampling.

[0004] However, after the above patent has been improved, there is still a problem that after the sampling is completed, there is a lack of self-locking structure, which makes it easy to accidentally touch the pressure plate, causing the internal pressure of the sampler to increase and discharge the sample, and the bottom of the needle tube cannot be closed, which makes it easy for the extracted sample to flow out accidentally. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a sampler for medical testing, which solves the problems raised in the above-mentioned background technology.

[0009] Preferably, a spherical clamp block is rotatably installed inside the spherical groove and at the top of the sampling tube, a through groove is opened inside the spherical clamp block, a connecting rod is fixedly installed on one side of the spherical clamp block, and the connecting rod is rotatably connected to the inside of the tube body. By rotating the spherical clamp block, the end with the through groove is rotated to one side of the spherical groove, and the arc surface of the spherical clamp block is facing upward, so as to close the spherical groove inside the tube body and prevent the sampled liquid from flowing out and causing contamination.

[0010] Preferably, second clamping blocks are fixedly installed on both sides of the connecting rod, a rotating block is provided on one side of the tube body, and two third clamping blocks are fixedly installed on one side of the rotating block, a third slot is opened on one side of the tube body, the third clamping block is inserted into the interior of the third slot, a second slot is opened inside the rotating block, the connecting rod is inserted into the interior of the second slot, a rotating groove is opened inside the rotating block and on one side of the second slot, the connecting rod is inserted into the interior of the rotating groove and is rotatably connected thereto, the rotating block is pulled out to make the third clamping block disengage from the interior of the third slot, and at this time the second slot is pulled from the interior of the rotating groove to the interior of the second slot, and the rotating block can be rotated to rotate the spherical clamping block.

[0011] Preferably, a first auxiliary block is fixedly mounted on one side of the rotating block, and both sides of the first auxiliary block are arc-shaped surfaces, which facilitates the staff to pull out the rotating block.

[0012] The utility model provides a sampler for medical examination, which has the following beneficial effects:

[0013] 1. The sampler for medical examination fixes the second auxiliary block on the top of the tube body. After the sample is extracted, the spring is reset to insert the limit block into the corresponding limit groove to limit the slide bar and prevent the slide bar from moving into the tube body again, thereby avoiding the sample being discharged due to the increase of the internal pressure of the sampler due to the push-pull plate being touched by mistake.

[0014] 2. The sampler for medical testing rotates the spherical block to rotate one end of the through groove to one side of the spherical groove, and faces the arc surface of the spherical block upward to seal the spherical groove inside the tube body to prevent the sampled liquid from flowing out and causing pollution.
