Description

Technical Field

[0001] The utility model relates to a cervical sampler, in particular to a side-push type cervical sampler with a manually retractable sampling head function. Background Art

[0002] The function of the cervical sampler is to take cells from the female vagina, and then analyze them through the hospital's detection equipment to understand whether the cervix and secretions are in a normal state. In the document with publication number CN211049441U, a side-push cervical sampler is proposed, including an insertion tube, a power component and a sampling rod; the power component includes a shell connected to the insertion tube as a whole, a push plate, a fan tooth and a rack, the axis of the fan tooth is rotatably connected in the shell, the fan tooth includes a first fan tooth part and a second fan tooth part arranged around the axis, the first fan tooth part and the second fan tooth part are arranged on both sides of the axis, and the radius of the first fan tooth part is smaller than the size of the second fan tooth part; the rack is arranged inside the shell in the axial direction, and one end of the rack is detachably connected to the sampling rod; the first fan tooth part is partially exposed outside the shell, and the exposed part of the first fan tooth part is meshed with the push plate; the second fan tooth part is meshed with the rack. When the push plate is pushed, the sampling rod can be telescoped by the fan teeth. The structure of this technology is relatively simple, making the operation more convenient. When the above-mentioned cervical sampler is in use, a push plate and fan teeth are used to extend and retract the sampling rod. However, during use, the position of the push plate needs to be confirmed before the fingers can push the push plate. Confirming the position of the push plate also takes a certain amount of time, which affects the speed of gynecological testing. Utility Model Content

[0013] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] (1) The utility model is a side-push cervical sampler with a manually retractable sampling head function. The lower pressure plate is inserted into the interior of the built-in tube, and the bottom end of the lower pressure plate contacts the top end of the lower moving plate. The hemisphere, the trapezoidal tube and the push tube are inserted into the vaginal opening, and the outlet hole contacts the cervical opening. At this time, the thumb presses the pressing circular plate, and the lower pressure plate is driven by the lower push rod to apply force to the lower moving plate. At this time, the lower moving plate moves downward. Since the side slider installed at the side end of the lower moving plate moves inside the spiral groove, the lower moving plate drives the sampling cotton swab to move downward in a rotational manner. Since the compression spring is movably installed at the bottom end of the lower moving plate, the compression spring contracts, and the sampling cotton swab moves out from the outlet hole to sample the cervix;

[0016] (2) The utility model provides a side-push cervical sampler with a manually retractable sampling head function. After sampling is completed, the thrust on the propulsion mechanism is released. At this time, the compression spring uses its own restoring force to push up the lower plate, and the sampling cotton swab is driven to rise in a spiral through the lower plate. The sampling cotton swab carries the sample back to the interior of the trapezoidal tube, and the sampling tube is pulled out. When the side slider moves, the rotating ball rotates on the outer surface of the limit rod to facilitate the movement of the side slider. BRIEF DESCRIPTION OF THE DRAWINGS
