Description

Technical Field

[0001] The present invention relates to the field of clinical sampling devices, in particular to a diagnostic sampling device for clinical internal medicine. Background Art

[0002] The internal medicine clinical diagnostic sampling device is a medical device designed specifically for rectal sampling. It enters through the anus and can quickly and accurately complete rectal sampling without causing discomfort to the patient. In clinical applications, the internal medicine clinical diagnostic sampling device provides doctors with a reliable diagnostic basis, helps to detect and treat related diseases early, and protects the health of patients.

[0003] However, most of the existing clinical diagnostic sampling devices for internal medicine on the market require medical staff to manually insert the sampling device through the anus into the rectum to complete the sampling operation. This method is more laborious and affects the flexibility and accuracy of the sampling operation. In addition, when the existing clinical diagnostic sampling devices for internal medicine on the market draw out samples, tissues inside the patient's rectum and anus may come into contact with the samples, which may cause the samples to be contaminated, thereby affecting the accuracy of the diagnostic results.

[0011] Preferably, the No. 1 adjusting disk slides inside the No. 1 sliding groove;

[0012] Through the above technical solution, the No. 1 adjusting disk can be easily and smoothly moved through the No. 1 slide groove.

[0013] Preferably, a crank is fixedly connected to the edge of the outer wall of the front end of the turntable, and a sleeve is rotatably connected to the middle of the outer wall of the crank;

[0014] Through the above technical solution, it is convenient for medical staff to hold the crank handle with the sleeve, and then exert force to rotate the turntable, thereby rotating the driving threaded rod, so that the No. 1 adjustment disk moves inside the No. 1 slide groove, and then the adjustment disk moves the arc plate connected to it with the No. 2 adjustment disk, thereby adjusting the position of the sampling needle inside the No. 2 slide groove, and making it convenient for medical staff to perform sampling operations with the help of the sampling needle.

[0015] Preferably, the second adjusting disk slides inside the second chute;

[0016] Through the above technical solution, the stability of the movement of the No. 2 adjusting disk can be improved through the No. 2 slide groove.

[0017] Preferably, the outer wall of the sampling needle is in close contact with the contact surface of the blocking sheet;

[0018] Through the above technical solution, the blocking sheet is used to prevent tissue inside the patient's rectum and anus from entering the interior of the No. 2 chute through the gap between the sampling needle and the blocking sheet.
