Example Embodiment

[0010] Example 1. Three bags, upper, middle and lower, are sewn with fabric. The fabric itself is a filter. figure 1 After the structure is sewn, coat the outer walls of the three bags with hydrophobic or water-resistant paint. Or use a waterproof cloth as a bag, and the filter is fixed with a thin fabric such as gauze or a perforated non-woven fabric by stitching, bonding, or welding, but the seam should be waterproofed.

[0011] The bag mouth of the upper bag is provided with a frame 6. The upper bag is especially a wide bag, and the bag mouth support 7 can be fixed on the frame. The bag mouth frame can be collected on a clamping table. A filter screen is arranged between adjacent bags to make the upper and middle bags opaque and the lower bag more transparent. There is a filter net between each bag is a fabric (it can be a thin fabric such as gauze), and the green nets of the upper and middle bags are clamped by clips. First clip on the filter screen with a clip, then add a ...

Example Embodiment

[0013] Example 2. A disposable soft plastic cup (especially a longer-length cylinder or cup) is prepared by blister or injection molding, and a filter is added to the above-mentioned cylinder structure. 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. Each cup is a self-molding soft plastic, which can also be clamped by a clamp during use (the substance and liquid do not directly contact the filter. Do not let the washing liquid leak). The filter screen of this embodiment can also be used in the filter screen structure of embodiment 1 (especially non-woven material).

Example Embodiment

[0014] Example 3 is the same as the bag of Example 1. The bag is made of plastic film material, and the filter screen adopts the structure of Example 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...
