the utility model provides an anti-seepage partition plate, includes plate body 1, and the upper end of plate body 1 is equidistant to be provided with a plurality of guiding gutters 3, and the both ends of plate body 1 are provided with album liquid box 2, and the inner chamber cavity of collection liquid box 2, and album liquid box 2 has seted up plate body slot 4 towards one side of plate body 1, and collection liquid box 2 corresponds every guiding gutter 3's position towards plate body 1 one side and has all seted up water conservancy diversion hole 5, the lower edge of water conservancy diversion hole 5 with the alignment of guiding gutter 3, and the inner chamber of water conservancy diversion hole 5 intercommunication collection liquid box 2 still be provided with on the plate body 1 and scrape strip 18, scrape the length of strip 18 with the width looks adaptation of plate body 1, scrape the downside of strip 18 with for the sliding fit who pastes tightly each other between the upside of plate body 1, be provided with stay cord 19 on scraping the strip 18, the length of stay cord 19 is greater than the width of plate body 1.

In this embodiment, preferably, the inner wall of the diversion trench 3 is sprayed with a polytetrafluoroethylene coating, the center of the trench bottom of the diversion trench 3 protrudes upward, and two ends of the trench bottom are inclined outward and downward; the polytetrafluoroethylene coating is arranged to prevent liquid from adhering to the inner wall of the diversion trench 3, so that the diversion effect of the diversion trench 3 is improved, and the two ends of the trench bottom are inclined outwards and downwards, so that the liquid falling into the diversion trench 3 can automatically flow out to two sides under the action of gravity, and the diversion effect is improved;

in the solution of the present application, by providing the wiper strip 18, when there is a liquid leak, by pulling the wiper strip 18, the wiper strip 18 slides between the plate body 1 and the nonwoven fabric layer 11, in this sliding, on the one hand, the liquid on the plate body 1 is hung in the guiding groove 3, and on the other hand, more importantly, when the scraping strip 18 scrapes, not only the scraping strip scrapes the plate body 1, but also the non-woven fabric layer 11 and the liquid attached to the lower side of the patient body, the liquid in the non-woven fabric layer 11 and the lower part of the patient clothes can be squeezed out, when the liquid flows out, due to the existence of the scraping strip 18, the extruded liquid seriously flows into the chute by the scraping strip 18, so that after the doctor blade 18 has passed over the nonwoven layer 11, the liquid on it is greatly reduced, while the nonwoven material itself is thinner, so the residual liquid can be evaporated and dried quickly, and the comfort of the patient is greatly improved in such a way; furthermore, especially when the liquid is viscous liquid such as blood, body tissues or gastric juice, the method can directly avoid the problem that the crusts of the liquid on the single sheet are hardened, so that the whole bed sheet and clothes of a patient are completely scrapped, and also greatly reduces the risk of pathogenic infection and infection caused by the liquid.

Preferably, in the width direction of the bed body 9, one side of the scraping strip 18 is in a wedge-shaped inclined plane shape, and the other side is in an arc surface shape which is in smooth transition from the top end to the bottom end. The wedge-shaped inclined plane shape is favorable for the scraping strip 18 to enter between the non-woven fabric layer 11 and the plate body 1, and avoids the problem of curling the non-woven fabric layer 11 in the sliding process of the scraping strip 18 along the plate body 1, and the other side of the scraping strip 18 is in the shape of an arc surface in smooth transition from the top end to the bottom end, so that when the scraping strip 18 scrapes the lower part of a human body, the upper edge of the wedge-shaped inclined plane can form extrusion, the arc-shaped top surface and the back of the wedge-shaped inclined plane can form support of a larger area, and discomfort of a patient is reduced.
