阅读说明：本技术 带滤过功能的切口保护膜 (Incision protection film with filtering function ) 是由 王婧 田国辉 于 2019-11-15 设计创作，主要内容包括：本发明公开了一种带滤过功能的切口保护膜,其包括贴膜,在所述贴膜一侧设有集液袋,在所述集液袋内设有滤网。本发明的优点：结构简单,使用方便,通过滤网有效取出细小手术病理,防止有效标本信息的流失,将标本收集袋置于整个集液袋的内层的上半部分,可以实现无菌平面的上移,在手术操作者的手术中手术医生可以随时从过滤网中拾取标本并且处于无菌平面以上,防止医生留取标本时由于口袋位置低于手术无菌平面造成操作污染；拓宽了手术使用范围,既适应传统大切口手术使用,更适应于现代微创手术技术的发展。(The invention discloses an incision protection film with a filtering function, which comprises a film, wherein a liquid collection bag is arranged on one side of the film, and a filter screen is arranged in the liquid collection bag. The invention has the advantages that: the sample collection bag is arranged at the upper half part of the inner layer of the whole liquid collection bag, so that the upward movement of a sterile plane can be realized, a surgeon can pick up a sample from the filter screen at any time in the operation of an operator and the sample can be positioned above the sterile plane, and the operation pollution caused by the fact that the position of a pocket is lower than the sterile plane in the operation when the surgeon keeps the sample is prevented; the operation range is widened, and the device is not only suitable for the traditional large incision operation, but also more suitable for the development of the modern minimally invasive operation technology.)

1. The incision protection film with the filtering function comprises a film, wherein a liquid collection bag is arranged on one side of the film, and the incision protection film is characterized in that a filter screen is arranged in the liquid collection bag.

2. The incision protection film with a filtration function of claim 1, wherein the filter screen is a pocket, and a pocket opening of the filter screen is fixed on an inner wall of the liquid collection bag.

3. The incision protection film with the filtration function of claim 1, wherein the filter screen is in a pocket shape, and a filter screen adhesive strip is arranged on the outer wall of the mouth of the filter screen pocket; the filter screen in the pocket is separately stuck and fixed on the inner wall of the liquid collecting bag through the filter screen sticking strip.

4. A notch protection film with filtration function as claimed in any one of claims 1 to 3, wherein a liquid guide tube is provided at the bottom of the liquid collection bag, and a stop valve is provided on the liquid guide tube.

5. The incision protection film with filtration function according to any one of claims 1 to 3, wherein an iodophor coating is provided on the surface of the adhesive film.

6. The incision protection film with filtration function according to claim 4, wherein an iodophor coating is provided on the surface of the patch.

The technical field is as follows:

the invention relates to a medical instrument, in particular to an incision protection film with a filtering function used in an operation.

Background art:

the existing incision protection film is only suitable for being stuck to an operation part to carry out aseptic protection on an operation incision or contain liquid for flushing the incision in an operation to prevent an operation drape around the incision from being polluted. The washing liquid contains a lot of valuable tiny or tiny operation specimen information, the existing incision protection film can not effectively take out tiny operation pathology contained in the washing liquid, for example, in a minimally invasive gallbladder-protecting and stone-taking operation, because of different stone components, stones or gallbladder polyps which can be directly taken out by a surgical instrument can be removed, and part of silt-like stones or electrocoagulated polypus tissues can be mixed in a large amount of washing media and can not be taken out to cause partial loss of specimen information; meanwhile, when the medical liquid collecting bag is used, after the abdominal incision protection film is fixed, the liquid collecting bag is positioned on the side face or the lower face of the incision of a patient, the lowest part of the liquid collecting bag is lower than an operation sterile operation plane and even exceeds a place covered by a sterile towel, the liquid collecting bag is considered as a polluted part, if an operator wants to collect and check pathological specimens in real time in an operation, the pathological specimens can be collected only at the tail end, the height is reduced, or the hand is lower than the operation plane, so that the aseptic technical operation principle is violated, and the information.

The invention content is as follows:

the invention aims to provide an incision protection film with a filtering function, which can effectively take out tiny surgical pathology and prevent effective specimen information loss and pollution.

The invention is implemented by the following technical scheme: the incision protection film with the filtering function comprises a film, wherein a liquid collection bag is arranged on one side of the film, and a filter screen is arranged in the liquid collection bag.

Preferably, the filter screen is in a pocket, and the mouth of the filter screen in the pocket is fixed on the inner wall of the liquid collecting bag.

Preferably, the filter screen is in a pocket, and a filter screen adhesive strip is arranged on the outer wall of the opening of the filter screen in the pocket; the filter screen in the pocket is separately stuck and fixed on the inner wall of the liquid collecting bag through the filter screen sticking strip.

Preferably, a liquid guide pipe is arranged at the bottom of the liquid collection bag, and a stop valve is arranged on the liquid guide pipe.

Preferably, an iodophor coating is arranged on the surface of the film.

The invention has the advantages that: the sample collection bag is arranged at the upper half part of the inner layer of the whole liquid collection bag, so that the upward movement of a sterile plane can be realized, a surgeon can pick up a sample from the filter screen at any time in the operation of an operator and the sample can be positioned above the sterile plane, and the operation pollution caused by the fact that the position of a pocket is lower than the sterile plane in the operation when the surgeon keeps the sample is prevented; the operation range is widened, and the device is not only suitable for the traditional large incision operation, but also more suitable for the development of the modern minimally invasive operation technology.
