Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an anti-pollution device and a collection method for collecting intestinal fecal fluid and gas during colonoscopy diagnosis and treatment. Background Art

[0002] Before undergoing colonoscopy, patients need to take 2 to 3 liters of laxatives and water orally for intestinal preparation, which will form a large amount of fecal fluid in the intestine. Even with multiple bowel movements, the fecal fluid in the intestine cannot be completely eliminated. Sometimes, in order to clearly examine the intestinal wall, water needs to be injected into the intestine to flush the intestinal wall. In addition, during colonoscopy, in order to facilitate the entry of the colonoscope into the intestine or fill the intestinal cavity, gas needs to be injected into the intestine to expand the intestinal cavity. The above situations will cause a large amount of fecal fluid or fecal fluid gas and other impurities in the intestine. Regardless of whether the patient's anal sphincter is relaxed or not, fecal fluid will flow out of the anus. Even due to the excessive expansion of the intestinal cavity caused by the injection of gas, intestinal peristalsis will be stimulated, causing gas and fecal fluid to be ejected from the anus. The outflowing or ejected impurities splash onto the body and clothing of patients, medical staff, and related items and equipment for diagnosis and treatment, greatly polluting the diagnosis and treatment environment and reducing the satisfaction and comfort of patients and medical staff throughout the diagnosis and treatment process. However, there is currently no relevant equipment and technology to solve this problem. Summary of the Invention

[0020] like Figures 1 to 3 As shown, this embodiment provides a fecal liquid and gas collection system for colonoscopy diagnosis and treatment, which includes a cylindrical catheter 1 with an inner end and an outer end both open, the inner end of the cylindrical catheter 1 is provided with an expandable fixed cuff 2, the fixed cuff 2 is coated on the outer side wall of the cylindrical catheter 1 and is connected to an extension tube 10, the extension tube 10 extends to the outer end of the cylindrical catheter 1, the fixed cuff 2 is an inflatable or water-filled silicon capsule, and its diameter expands to 1.5 to 5 times the diameter of the cylindrical catheter 1 after filling. In this embodiment, the inflatable type is preferred, and a PVC air drum is installed at the outer end of the extension tube 10. The PVC air drum is The prior art is not described here in detail. The fixed cuff 2 is pumped with air by pressing the PVC air drum. The outer end of the cylindrical catheter 1 is covered with an elastic membrane 3. A colonoscope through hole 4 is opened in the center of the elastic membrane 3. The elastic membrane 3 is made of medical PE film. The outer edge of the medical PE film is heat-sealed to the outer end of the cylindrical catheter 1. The wall of the cylindrical catheter 1 near the outer end is provided with an open section 5. The open section 5 is provided with a plurality of fecal liquid and gas through holes. The outside of the open section 5 is covered with a fecal liquid and gas collection bag 6. The fecal liquid and gas collection bag 6 is connected to the fecal liquid and gas collection container through a drainage tube. The outer wall of the cylindrical catheter 1 is integrally injection-molded with an anal retaining ring 8 and an indented fitting groove 9. The anal retaining ring 8 is arranged between the fixed cuff 2 and the feces, liquid and gas collection bag 6. The outer end of the extension tube 10 passes through the anal retaining ring 8 and extends outside the body; the anal retaining ring 8 and the axial direction of the cylindrical catheter 1 form an angle of 45 to 90 degrees, and the outer edge of the anal retaining ring 8 is designed to fit the anal skin; the inner end of the indented fitting groove 9 terminates at the fixed cuff 2, and the outer end terminates at the feces, liquid and gas collection bag 6. The indented fitting groove 9 is arranged along the axial direction of the cylindrical catheter 1, and the extension tube 10 is pre-buried in the indented fitting groove 9; In order to prevent the colonoscope from rubbing against the inner wall of the cylindrical catheter 1 when advancing and retracting, a plurality of strip silicone pads 7 are provided on the inner tube wall of the inner end of the cylindrical catheter 1 in this embodiment. The length direction of the strip silicone pad 7 is provided along the axial direction of the cylindrical catheter 1, and the strip silicone pad 7 is fixed to the inner wall of the cylindrical catheter 1 by heat welding.

[0021] The collection method of the fecal liquid and gas collection system for colonoscopy diagnosis and treatment in this embodiment is as follows: The cylindrical catheter 1 in the present invention is about 10 cm long, with an inner diameter larger than the outer diameter of the colonoscope and open at both ends. The inner end of the cylindrical catheter 1 is inserted through the anus to a position above the anal papilla until the anus abuts against the anal retaining ring 8. The PVC air drum is pressed to fill the inner end fixing cuff 2. The inner end fixing cuff 2 locks the cylindrical catheter 1 at the junction of the rectum and the anal canal. At this time, the cylindrical catheter 1 is fixed, which can effectively prevent the cylindrical catheter 1 from slipping out of the intestine. The colonoscope is passed through the colonoscope through hole 4 and the cylindrical catheter 1 into the rectum. Since the medical PE film has strong elasticity and tensile strength, the diameter of the colonoscope through hole 4 is smaller than the outer diameter of the colonoscope rod, and the medical PE film will be wrapped around the outer wall of the colonoscope rod in a tensioned state. During the process of inserting or removing the colonoscope through the colonoscope through-hole 4, the unique tensile strength of the medical PE film can ensure that it plays a sealing role. At this time, the outer wall of the fixed cuff 2 in the filled state is tightly attached to the intestinal tract of the rectum, and feces, liquid and gas cannot enter the gap between the fixed cuff 2 and the rectum. Feces, liquid and gas are forced to enter the inner cavity of the cylindrical catheter 1. The overflowed feces, liquid and gas are blocked by the elastic membrane 3 at the outer end and enter the feces liquid and gas collection bag 6 through the feces liquid and gas through-hole, and finally enter the feces liquid and gas collection container through the drainage tube; collecting waste through this collection system can prevent waste from flowing out or spraying out of the anus during colonoscopy diagnosis and treatment, reduce pollution of the diagnosis and treatment environment, and improve the satisfaction and comfort of patients and medical staff.

[0022] Anything not described in detail in the present invention is well known to those skilled in the art.

[0023] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
