Problems solved by technology

When there are a little more solid fragments, plus blood and intercepted tissues are mixed to accelerate the formation of blood clots, the speed of clogging the filter will be further accelerated, because the inside of the filter is not separated, when the accumulation reaches a certain amount, due to gravity The reason will also reduce the degree of attraction and affect the attraction effect. It will squeeze and accumulate on the filter screen, which will easily block the filter screen and cause the filter screen to lose its effect. At the same time, it is inconvenient to clean or replace the traditional filter. The Internet will bring unpredictable risks

Abstract

The invention discloses a medical suction filter, which comprises an outer shell piece and an upper cover piece, and the outer shell piece comprises an outer shell body and a liquid outlet pipe arranged at the bottom of the outer shell body; the upper cover piece comprises an upper cover body and a liquid inlet pipe arranged at the top of the upper cover body; the shell body and the upper cover body are connected to form a filtering cavity; a filtering piece is arranged in the filtering cavity and comprises an inner cup body, and filtering holes are formed in the inner cup body; the width value of the gap between the inner cup body and the upper cover body is a, the diameter value of the filtering hole is b, the width value of the gap between the inner cup body and the outer shell body isc, the hole diameter value of the liquid outlet pipe is d, and a is smaller than b, b is smaller than c, and c is smaller than d, so that the problem that a filter in the prior art is prone to being blocked is solved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a medical suction filter. Background technique [0002] Medical filters are often used in orthopedics, brain surgery, and intraoperative filtration and interception of blood clots, bone fragments, shed or resected fragments that are not easy to clamp. [0003] Traditional filtration is to intercept all solid fragments above the filter screen as much as possible, that is, to do everything possible to prevent all solid fragments from passing through the filter screen. When there are a little more solid fragments, plus blood and intercepted tissues are mixed to accelerate the formation of blood clots, the speed of clogging the filter will be further accelerated, because the inside of the filter is not separated, when the accumulation reaches a certain amount, due to gravity The reason will also reduce the degree of attraction and affect the attraction effect. It will squeeze and ...
