Problems solved by technology

[0002] The currently routinely used screening method for colon cancer is to use fecal occult blood test, which is widely used due to its simplicity, but the specificity of this method is low, and the false positive rate is more than 90%.
Molecular biological examination using exfoliated cells in feces has high sensitivity and specificity in theory, but because less intestinal mucosa is collected, the sensitivity is low, so collecting enough intestinal mucosa is the key to further research. However, if the amount of feces is large, it is difficult to handle, and it is difficult for both the patient and the examiner to accept

Embodiment 1

[0010] Embodiment 1, adopt upper, middle and lower three bags, sew with fabric, fabric itself is filter screen, press figure 1 After the structure is sewn, the outer walls of the three bags are coated with hydrophobic or water-proof paint. Or make a bag with a waterproof cloth, and the filter screen is fixed with a thin fabric such as gauze or a non-woven fabric with holes by sewing, bonding or welding, but the weaving seam should be waterproofed.

[0011] The bag opening of the upper bag is provided with a frame 6, and the upper bag is especially a wide pocket, and the frame can be fixedly provided with a pocket support 7. Equipped with a bag mouth frame for collection operations on a holding table. A screen is provided between adjacent bags to make the upper and middle bags opaque while the lower bag is more transparent. There is a filter screen between each bag to be fabric (it can be thin fabrics such as gauze), and there are clips on the green nets of the upper and midd...

Embodiment 2

[0013] Embodiment 2, prepare disposable soft plastic cup body (especially make length longer cylinder body or cup body) with blister or injection molding mode, add filter screen on above-mentioned cylinder structure, the filter screen The outer diameter is the same as the inner diameter of the cup, and the filter screen (the filter screen can be installed on an outer ring) is welded to a certain position of the long cylinder by means of ultrasonic welding. In fact, there are three cups in a thin-walled plastic cylinder that can be self-molded, and each cup is a self-molding soft plastic, which can also be clamped by clips during use (at this time, the liquid does not directly contact the filter screen, Do not let the washing liquid leak). The filter screen of this embodiment can also be used for the filter screen structure of Embodiment 1 (especially the non-woven fabric material).

Embodiment 3

[0014] Embodiment 3, with the bag of embodiment 1, adopt plastic film material to prepare bag, filter screen adopts the structure of embodiment 1. The volume of each bag is unlimited, even reaching about 1 liter.

Abstract

The invention relates to an intestine mucosa collector comprising at least three bags connected sequentially from top to bottom. A filter screen, i.e., the bottom of an upper bag is arranged between the adjacent bags; the bottom bag is the non-leakage bag bottom; the upper bag, the middle bag and the lower bag especially formed by sewing with fabric are used; the filter screen is fixed in the sewing, splicing or welding manner by using thin fabrics of gauze and the like or non-woven fabrics with holes. The invention provides a device for collecting excrement, called as a disposable intestine mucosa collector, is convenient for inspectors to operate, has good collection effect and low cost, can be made of environmental-friendly materials and can collect more intestine mucosa, thereby being convenient for inspecting personnel and patients.

Description

technical field [0001] The invention relates to a device for collecting and treating excrement so as to facilitate medical examination. Background technique [0002] The currently routinely used screening method for colon cancer is to use fecal occult blood test, which is widely used because of its simplicity, but its specificity is low, and the false positive rate is more than 90%. Using exfoliated cells in feces for molecular biological examination has high sensitivity and specificity in theory, but because the collected intestinal mucosa is less, the sensitivity is low, so collecting enough intestinal mucosa is the key to further research. However, if the amount of feces is large, it is difficult to handle, and it is difficult for both the patient and the examiner to accept it. Contents of the invention [0003] The object of the present invention is to propose a device for collecting and processing excreta, also known as a disposable intestinal mucosa collector, and a...
