Description

Technical Field

[0001] This utility model relates to the field of medical consumables technology, specifically to a disposable endoscope anti-fecal-contamination wipe. Background Technology

[0002] With the popularization and development of digestive endoscopy technology, endoscopy has become an important means of diagnosing and treating digestive tract diseases. However, in actual operation, due to insufficient bowel preparation or abnormal bowel function, leakage of intestinal contents often occurs. This not only seriously contaminates the surgical environment and increases the workload of medical staff, but also may bring the risk of nosocomial infection.

[0003] Currently, the following methods are mainly used clinically to address contamination during endoscopic examinations: First, enhanced preoperative bowel preparation, such as using laxatives to empty the bowels as much as possible; however, this method is not effective for elderly patients or those with abnormal bowel function. Second, placing absorbent pads or nursing pads under the patient's buttocks; this method only passively receives contaminants and cannot prevent spray contamination. Third, using simple plastic baffles; however, these devices are difficult to secure and cannot address odor issues. Each method has its advantages and disadvantages: bowel preparation is inconsistent in effectiveness, absorbent pads provide incomplete protection, and baffles offer poor comfort. In recent years, with the widespread use of disposable medical supplies, developing a dedicated anti-contamination device for endoscopic examinations has significant clinical and market value. Utility Model Content

[0004] The purpose of this utility model is to at least partially solve one of the technical problems in related technologies. In view of this, a disposable endoscope anti-fecal contamination cloth is provided, comprising: a perianal rubber ring with an adhesive surface, wherein the adhesive surface of the perianal rubber ring is provided with an easy-tear film; an anti-contamination cloth pocket, wherein the openings at both ends of the anti-contamination cloth pocket are connected through the middle, one end of the anti-contamination cloth pocket is fixedly connected to the side of the perianal rubber ring away from the adhesive surface, and the other end of the anti-contamination cloth pocket is open for the insertion of an endoscope; and a fecal water absorption structure, wherein the fecal water absorption structure is fixed to the inner wall of the anti-contamination cloth pocket close to the inner side of the perianal rubber ring, and the fecal water absorption structure is provided with a support hole for the endoscope to pass through.

[0005] Compared with the prior art, the technical solution of this utility model has the following advantages: Before use, the endoscope is passed through the distal opening of the anti-contamination drape and the support hole on the fecal water absorption structure. Then, the easy-tear film is peeled off and the perianal adhesive ring is attached to the patient's perianal area. This design provides a sealed and protective wrap around the perianal area, effectively preventing the contamination of the surgical environment by intestinal contents sprayed from the anus during the endoscopic examination. At the same time, the fecal water absorption structure absorbs the outflowing fecal water, solving the problem of collecting solid and liquid contaminants. In addition, the anti-contamination drape that seals over the outside of the perianal area can mask odors generated during the examination and prevent bacteria from spilling out, reducing the risk of nosocomial infection and improving the safety of medical staff.

[0006] According to one example of the present invention, an elastic rubber plug is included, which is fixed to an opening at the end of the anti-pollution cloth bag away from the perianal rubber ring.

[0007] According to one example of the present invention, the elastic plug includes a bottom ring, a conical shrink ring and an inner ring connected in sequence, wherein the inner ring is provided with a plurality of expansion slits extending to the conical shrink ring at equal intervals.

[0008] According to one example of the present invention, the anti-pollution cloth bag is retractable along the axial direction of the perianal rubber ring, and the anti-pollution cloth bag is hollow cone-shaped when fully stretched.

[0009] According to one example of the present invention, the sewage absorption structure is a microporous sponge block, or the sewage absorption structure is a non-woven fabric block embedded with highly absorbent polymer particles.

[0010] According to one example of the present invention, an exhaust gas adsorption and sterilization structure is attached to the upper inner wall of the anti-pollution cloth bag. The exhaust gas adsorption and sterilization structure includes a plurality of activated carbon fibers woven in a mesh, or the exhaust gas adsorption and sterilization structure is a chitosan nanofiber membrane.

[0011] According to one example of the present invention, a negative pressure connector for connecting a negative pressure suction tube is installed on the side wall of the anti-pollution cloth near the perianal rubber ring. The negative pressure connector is located directly below the fecal water absorption structure, and a sealing plug is connected to the outside of the negative pressure connector.

[0012] According to one example of the present invention, the inner ring of the perianal rubber ring is provided with an annular waterproof strip.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] [First Embodiment] Please see Figures 1-6As shown, this utility model provides a disposable endoscope-proof fecal-contaminated cloth, comprising: a perianal rubber ring 100 with an adhesive surface, the adhesive surface of which is provided with an easy-tear film 200; a fecal-contaminated cloth pocket 300, the two ends of which are open and connected in the middle, one end of which is fixedly connected to the side of the perianal rubber ring 100 away from the adhesive surface, and the other end of which is open for the endoscope to pass through; and a fecal-absorbing structure 400, which is fixed to the inner wall of the fecal-contaminated cloth pocket 300 close to the inner side of the perianal rubber ring 100, and has a support hole 401 for the endoscope to pass through.

[0024] In this embodiment, before use, the endoscope 900 is passed sequentially through the distal opening of the anti-contamination cloth 300 and the support hole 401 on the fecal water absorption structure 400. Then, the easy-tear film 200 is peeled off and the perianal adhesive ring 100 is attached to the patient's perianal area. This design provides a sealed and protective wrap around the perianal area, effectively preventing the problem of intestinal contents being sprayed from the anus and contaminating the surgical environment during the endoscopic examination. At the same time, the fecal water absorption structure absorbs the outflowing fecal water, solving the problem of collecting solid and liquid contaminants. In addition, the anti-contamination cloth 300, which seals over the outside of the perianal area, can shield the odor generated during the examination and prevent the leakage of bacteria, thereby reducing the risk of nosocomial infection and improving the safety of medical staff.

[0025] Preferably, the anti-pollution cloth bag 300 can extend and retract along the axis of the perianal rubber ring 100. In normal condition, the entire anti-pollution cloth bag 300 is flattened and compressed for easy storage. When in use, it is stretched to expand the internal storage space. When fully stretched, the anti-pollution cloth bag 300 is hollow cone-shaped. The wider end is used to accommodate the intestinal contents that overflow from the perianal area, while the narrower end is used to connect to the endoscope.

[0026] Preferably, the inner ring of the perianal rubber ring 100 is provided with an annular waterproof strip 500, which is used to tighten the inner edge of the perianal rubber ring 100 to increase its waterproof performance and prevent the perianal overflow liquid from wetting the annular waterproof strip 500 and causing it to fall off.

[0027] [Second Embodiment] Based on Embodiment 1 above, this embodiment makes one optimized design. The fecal contamination prevention cloth also includes an elastic rubber plug 600, which is fixed to the opening at the end of the fecal contamination prevention cloth pocket 300 away from the perianal rubber ring 100. The elastic rubber plug 600 has a stopper in the middle, which is adapted to the outer diameter of the colonoscope, so that after the colonoscope is inserted through the stopper, the elastic band can tightly wrap around the outer wall of the colonoscope due to the elastic wrapping force.

[0028] Preferably, the elastic rubber stopper 600 includes a bottom ring 601, a conical contraction ring 602 and an inner ring 603 connected in sequence. The inner ring 603 is provided with a plurality of expansion slits 604 that extend to the conical contraction ring 602 at equal intervals, for adapting to endoscope instruments with larger diameters.

[0029] [Third Embodiment] This embodiment, based on Embodiment 1 above, provides an exemplary design for the fecal water absorption structure 400, used to efficiently absorb solid and liquid intestinal contents overflowing from the perianal area. In a first feasible example, the fecal water absorption structure 400 is a microporous sponge block. The microporous sponge block can be made of open-pore polyurethane sponge for rapid liquid absorption, and can be further combined with a superabsorbent polymer to increase its capacity. In a second feasible example, the fecal water absorption structure 400 is a nonwoven fabric block embedded with superabsorbent polymer particles. The superabsorbent polymer particles can be cross-linked sodium polyacrylate particles, which can absorb hundreds of times their own weight in liquid to form a gel that locks in water. These particles are designed to be embedded in the nonwoven fabric interlayer to form a water-absorbing core layer.

[0030] [Fourth Embodiment] Based on Embodiment 1 above, this embodiment provides an exemplary design for the waste gas adsorption and sterilization structure 700, used to efficiently absorb polluted waste gas overflowing from the perianal area. The waste gas adsorption and sterilization structure 700 is attached to the upper inner wall of the anti-pollution cloth bag 300. In a first feasible example, the waste gas adsorption and sterilization structure 700 includes several activated carbon fibers woven in a mesh. The activated carbon fibers can be selected with a high specific surface area (500-1500 m² / g) to adsorb pathogen metabolites (such as indole, hydrogen sulfide) and VOCs, blocking the spread of pathogens. Alternatively, in a second feasible example, the waste gas adsorption and sterilization structure 700 is a chitosan nanofiber membrane. Natural chitosan adsorbs negatively charged bacteria / viruses through positive charge adsorption, and then degrades them to render them harmless.

[0031] [Fifth Embodiment] Based on Embodiment 1 above, this embodiment incorporates a negative pressure suction drainage design to address situations with large perianal overflow. A negative pressure connector 800 for connecting a negative pressure suction tube is installed on the side wall of the anti-contamination cloth 300 near the perianal rubber ring 100. The negative pressure connector 800 is located directly below the fecal water absorption structure 400. This negative pressure connector 800 can be connected to the negative pressure drainage tube of a hospital negative pressure suction system. Through negative pressure suction, excess overflowing liquid contaminants are extracted and discharged. A sealing plug 801 is connected to the outside of the negative pressure connector 800 to seal the negative pressure connector 800 under normal conditions.
