All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The embodiment of the utility model provides a human tissue filtering device, which is characterized in that a collection cavity with a large upper part and a small lower part is arranged to enable tissue fragments to be piled together, so that the contact area between the tissue fragments and the inner wall of the collection cavity is reduced, and in addition, the area of a filtering structure is reduced to enable the tissue fragments not to be easily adhered to the filtering structure, so that the tissue fragments in the collection cavity can be conveniently collected. The utility model solves the problems that the tissue fragments after being filtered in the related technology are easy to adhere to a filter screen cage or a filter cloth, and are difficult to collect the tissue fragments at one time.

Referring to fig. 1 to 3, a human tissue filtering apparatus includes a reservoir 1 and a collecting member 2, the reservoir 1 including a reservoir chamber 1a and a feed port 1b, the feed port 1b connecting the reservoir chamber 1a to the outside, and liquid and tissue fragments entering the reservoir chamber 1a through the feed port 1 b. The collecting member 2 is located in the reservoir 1a, the collecting member 2 comprises a collecting chamber 2a and a filter structure 2b, the filter structure 2b communicates the collecting chamber 2a with the reservoir 1a, and the feed inlet 1b communicates with the collecting chamber 2a, whereby liquid and tissue fragments enter the collecting chamber 2a from the feed inlet 1b and pass through the filter structure 2b, the tissue fragments remain in the collecting chamber 2a, and the liquid flows from the filter structure 2b into the reservoir 1a. Thus, the tissue fragments drain within the collection chamber 2a, facilitating subsequent collection and detection.

Referring to fig. 1 to 3, the collecting member 2 includes a collecting body 201 and a collecting cover 202, a collecting chamber 2a is provided in the collecting body 201, an opening of a top surface of the collecting body 201 is provided, and the collecting cover 202 is screw-coupled with the collecting body 201 and shields the opening of the top surface of the collecting body 201. The feed inlet 1b communicates with the collection chamber 2a via a feed pipe which extends into the collection chamber 2a through the feed inlet 1b and through the collection cap 202. The filtering structure 2b is positioned at the bottom of the collecting cavity 2a, after the liquid and the tissue fragments enter the collecting cavity 2a, the liquid leaves the collecting cavity 2a from the filtering structure 2b at the bottom of the collecting cavity 2a, and then the collecting cover 202 is opened, so that the drained tissue fragments can be poured out of the collecting cavity 2a, and the collection of the tissue fragments is completed.

Referring to fig. 3 and 4, the cross-sectional area of the collecting cavity 2a is gradually reduced from top to bottom, the collecting cavity 2a is in a funnel shape, that is, the collecting body 201 is in a hollow truncated cone shape, preferably, the collecting body 201 is in a hollow regular quadrangular pyramid shape or a triangular pyramid shape, the cavity wall of the collecting cavity 2a is formed by a plurality of planes, and the included angle edge of each plane is more beneficial to the sliding of tissue fragments. The space at the bottom of the collecting cavity 2a is smaller, tissue fragments are stacked at the bottom of the collecting cavity 2a, the tissue fragments are not easy to scatter to all parts of the collecting cavity 2a, and the tissue fragments are easy to form clusters, so that the contact area between the tissue fragments and the inner wall of the collecting cavity 2a is smaller, and when the drained tissue fragments are poured out, the stacked tissue fragments are easy to be poured out together. In addition, because the filtering structure 2b is arranged at the bottom of the collecting cavity 2a, the contact area between the filtering structure 2b and the tissue fragments is small, the tissue fragments are not easy to adhere to the tissue fragments, even if the filtering structure 2b is adhered with the tissue fragments, the tissue fragments can be conveniently separated from the filtering structure 2b through the beating operation, and the collection of the tissue fragments is facilitated.

Referring to fig. 2-4, specifically, the filtering structure 2b includes a filtering hole formed in the bottom wall of the collecting cavity 2a to communicate the collecting cavity 2a with the liquid storage cavity 1a, when the liquid and the fragments of the tissue enter the collecting body, the tissue will be blocked at the filtering hole, and the size of the filtering hole is slightly smaller than the average size of the tissue, so that the tissue can be prevented from sliding down directly, and thus the tissue is accumulated at the filtering hole, and the liquid seeps downwards from the gap between the tissues and finally leaks into the liquid storage cavity from the filtering hole. After the liquid flows into the liquid storage cavity, only the filtered tissue sample is remained in the collecting cavity, and then the collecting body is detached, so that the tissue sample can be directly poured out, the better effect of separating the tissue sample from the liquid is achieved, and the tissue is easy and convenient to pour out, does not produce adhered tissue and does not need secondary cleaning.

In other embodiments, the number of filter holes may be plural, or the filter structure 2b may further include a filter tank.

The inner wall of the collecting chamber 2a is covered with a lubrication layer, in this embodiment, the material of the collecting body 201 is polytetrafluoroethylene, so that the material of the inner wall of the collecting chamber 2a is polytetrafluoroethylene, so as to form the lubrication layer. Because the sliding friction coefficient of the inner wall of the collecting cavity 2a is smaller, the wall hanging condition is not easy to occur when the tissue fragments are poured out, and the tissue fragments are convenient to pour out once.

Referring to fig. 3-5, in some embodiments, the body tissue filter device further comprises a filter tube 3, the filter tube 3 comprising a filter section 301 and a water outlet section 302.

To communicate the filter segment 301 with the reservoir 1a. The liquid in the collection chamber 2a can thus pass through the mesh structure 301a from the outside of the filter section 301 into the inside of the filter section 301 and finally from the outlet section 302 into the reservoir chamber 1a. The tissue fragments are deposited on the circumferential outer side of the filter segment 301, so that liquid between the tissue fragments easily flows into the filter segment 301 through the mesh structure 301a, accelerating the draining process of the tissue fragments.

Referring to fig. 3-5, further, the circumferential outer side of the filter segment 301 contacts the wall of the filter aperture, and when the filter segment 301 is withdrawn from the collection chamber 2a, the edge of the filter aperture scrapes off tissue fragments adhering to the circumferential outer side of the filter segment 301, so that the tissue fragments remain in the collection chamber 2a, and the possibility of the tissue fragments adhering to the outer wall of the filter segment 301 is reduced. In addition, even if the tissue fragments leave the collection chamber 2a with the filter segment 301, it is convenient to collect the tissue fragments on the outer side of the filter segment 301 because the tissue fragments adhere to the outer side of the filter segment 301. The filter tube 3 is made of polytetrafluoroethylene.

Wherein, when tissue fragments are filtered in the collecting piece 2, the filtering tube 3 is fixed on the collecting piece 2 under the action of the connecting component 4 so as to maintain the state that the filtering tube 3 extends to the collecting cavity 2a. In addition, the connection of the filter tube 3 to the collecting member 2 can be released by rotating the fitting sleeve 402 with respect to the collecting member 2, so as to facilitate the extraction of the filter tube 3 from the collecting chamber 2a.
