The above-mentioned negative pressure drainage collection device, wherein, the cylinder cover is also provided with a suction tube communicating with the cylinder body; the solid-liquid separation bag also includes a cap that can cover the mouth of the suction tube of the outer cylinder, and the cap is connected through a The belt is connected with the upper cover of the solid-liquid separation bag.

In the above-mentioned negative pressure drainage collection device, the cylinder body is made of plastic.

The above-mentioned negative pressure drainage collection device, wherein, the outer cylinder includes a soft bag arranged in the cylinder body, and the mouth of the soft bag is sealed and connected with the cylinder cover; the transparent bag body of the solid-liquid separation bag extends into the soft bag.

Because the utility model has adopted above technical scheme, the technical effect that it produces is obvious:

1. After adopting the above technical scheme, during the artificial abortion operation, the embryonic tissue, villi, amniotic fluid and blood can be sucked into the transparent bag through the suction tube set on the solid-liquid separation bag, and the amniotic fluid and blood will pass through The through hole on the transparent bag flows out into the outer cylinder, and the medical staff only need to take out the solid-liquid separation bag from the outer cylinder to observe the embryonic tissue and villi left in the transparent bag, thereby avoiding the medical staff from contacting with the outer cylinder. Direct contact between embryonic tissue, villi, amniotic fluid and blood water not only facilitates the operation, but also reduces the chance of cross-infection among operators;

2. The transparent bag body of the solid-liquid separation bag of the present invention is provided with a tear opening, and the embryo can be poured out for further inspection only by tearing the transparent bag body along the tear opening, and the operation is simple;

3. The body of the outer cylinder of the present invention is made of plastic material, which not only saves cleaning time, but also avoids cross-infection of medical staff as a disposable product.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

1 to 3 show a negative pressure drainage collection device according to a first embodiment of the present invention, including a solid-liquid separation bag 1 and an outer cylinder 2 .

The solid-liquid separation bag 1 includes a transparent bag body 11 with a tear seam 111 and an upper cover 12 . The transparent bag body 11 is provided with a plurality of small through holes 110 for the liquid to flow out. The upper cover 12 includes a cover body 121 and a suction tube 122 passing through the cover body, and the mouth of the transparent bag body 11 is connected with the lower end of the suction tube 122 .

The outer cylinder 2 includes a cylinder body 21 made of plastic and a cylinder cover 22 covering the mouth of the cylinder body. The cylinder cover 22 is provided with a convex tube 221 , a negative pressure tube 222 and a suction tube 223 communicating with the cylinder body. The central hole of the convex tube 221 allows the transparent bag body 11 of the solid-liquid separation bag to pass through.

The transparent bag body 11 of the solid-liquid separation bag 1 extends into the cylinder body 21 , and the cover body 121 of the upper cover 12 of the solid-liquid separation bag covers the convex tube 221 .

Preferably, the solid-liquid separation bag 1 further includes a cap 123 that can cover the mouth of the suction tube 223 of the outer cylinder, and the cap 123 is connected to the upper cover 12 of the solid-liquid separation bag through a connecting belt 124 .

4 to 6 show a negative pressure drainage collection device according to a second embodiment of the present invention, including a solid-liquid separation bag 1 and an outer cylinder 2a. In this second embodiment, the structure of the solid-liquid separation bag 1 is completely the same as that of the aforementioned first embodiment, but the structure of the outer cylinder is different. The outer cylinder 2a includes a cylinder body 21a, a cylinder cover 22a covering the mouth of the cylinder body, and a soft bag 23a disposed in the cylinder body 21a. The cylinder cover 22a is provided with a convex tube 221a, a negative pressure tube 222a and a suction tube 223a communicating with the cylinder body. The central hole of the convex tube 221a allows the transparent bag body 11 of the solid-liquid separation bag to pass through. The mouth of the soft bag 23a is sealed and connected with the cylinder cover 22a, and the transparent bag body 11 of the solid-liquid separation bag 1 extends into the soft bag 23a.

During the artificial abortion operation, the suction tube on the solid-liquid separation bag is connected to the external absorber through the pipeline, and the negative pressure tube on the outer cylinder is connected to the vacuum source through the pipeline, so that embryonic tissue, villi, amniotic fluid and blood are sucked Into the solid-liquid separation bag, the inhaled liquid part will flow into the outer cylinder through the through hole on the transparent bag body of the solid-liquid separation bag. Medical personnel only need to take out the solid-liquid separation bag from the outer cylinder to observe the embryonic tissue and villi left in the transparent bag, thereby avoiding direct contact between the medical staff and embryonic tissue, villi, amniotic fluid and blood.
