Abstract
Description
Technical Field
[0001] This utility model relates to the field of anal pouch technology, specifically an integrated anal pouch suitable for patients with severe bedridden diarrhea. Background Technology
[0002] Anal bags are mainly used in special situations such as anal incontinence, intestinal diseases, and postoperative care to help patients keep their skin dry and reduce the occurrence of complications. Anal bags are usually made of medical-grade silicone or other soft materials, which have anti-allergy, anti-aging, and anti-corrosion properties to ensure safety and comfort during use.
[0003] For example, patent CN217245084U discloses a novel anal pouch sleeve, including an anal pouch and a connecting tube. The connecting tube is fixedly inserted into the opening of the anal pouch and consists of a straight tube section and a Y-shaped head. One end of the straight tube section is fixedly connected to one end of the Y-shaped head, which is located inside the anal pouch. A branch tube is fixedly connected to the side wall of the straight tube section, located outside the anal pouch. The straight tube section, the Y-shaped head, and the branch tube are integrally formed and interconnected. By setting the connecting tube connected to the opening of the anal pouch as an integrally formed structure consisting of a straight tube section, a Y-shaped head, and a branch tube, while maintaining the Y-shaped head portion of the connecting tube... The anal bag is sealed within its inner cavity, maintaining a tight seal between the connecting tube and the bag. This allows patients or healthcare workers to simply attach the bag to the anus, making operation simple and convenient without requiring extensive preparation, thus improving ease of use. However, the anal bag has limited effectiveness in draining excrement, especially viscous excrement, which is prone to blockage during collection. Manual unclogging can produce odors and easily lead to leakage. Furthermore, as the amount of excrement collected increases, the airtight connection between the bag and the tube may cause some odor to leak out, affecting patients and surrounding caregivers.
[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing anal pouch. Utility Model Content
[0005] The purpose of this invention is to provide an integrated anal bag suitable for severely bedridden patients with diarrhea, in order to solve the problem mentioned in the background art that the anal bag has a limited drainage effect on excrement, especially for some viscous excrement, where blockage is easy to occur during the drainage and collection process, and manual unclogging and cleaning causes odor and leakage.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated anal bag suitable for severely bedridden patients with diarrhea, comprising an anal patch that adheres to the outside of the patient's perianal skin and a centrally located circular hole on the anal patch, wherein a guide bag for collecting the patient's excrement is connected to the anal patch, a guide interface is connected through the lower end of the guide bag, a drainage tube is snapped onto the guide interface, and a collection bag for collecting and measuring the patient's excrement is connected through the lower part of the drainage tube; the guide bag is provided with a flushing mechanism for diluting the excrement inside the guide bag to maintain unobstructed drainage.
[0007] Preferably, the collection bag is equipped with an internal threaded interface, which is internally threaded to an external threaded interface, and the external threaded interface is fixedly connected to the bottom of the drainage tube; the collection bag is provided with a hanging rope for its own auxiliary hanging and placement.
[0008] Preferably, the rinsing mechanism includes a rinsing port obliquely installed on the lower side of the guide bag, and a rinsing pipe is connected through the rinsing port.
[0009] Preferably, both the flushing tube and the drainage tube are flexible hoses, and the flushing tube and the drainage tube are externally fitted with elastic clamps that limit the size of the opening in the inner diameter of the tubes.
[0010] Preferably, the elastic tightening clamp is equipped with limiting teeth to restrict the tightening range.
[0011] Preferably, the collection bag is equipped with a deodorizing mechanism to reduce the odor of excrement.
[0012] Preferably, the deodorizing mechanism includes multiple breathable mesh covers connected at equal intervals inside the collection bag, the breathable mesh covers being curved and connected to the front and rear inner walls of the collection bag; the breathable mesh covers are provided with activated carbon particles that absorb the odor of excrement.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the integrated anal bag suitable for patients with severe bedridden diarrhea, the guide bag is attached to the patient's perianal area by an anal patch, and the excrement in the guide bag is controlled to enter the collection bag below by the drainage tube, thus maintaining the hygiene of the patient's perianal area.
[0014] Furthermore, the guide bag is equipped with a flushing mechanism to dilute the excrement inside the guide bag and maintain smooth drainage. When relatively viscous excrement enters the guide bag, the excrement is difficult to pass through the drainage tube into the collection bag below. At this time, flushing fluid is added to the inside of the guide bag through the flushing tube to dilute the excrement inside and assist the excrement in being drained into the collection bag.
[0015] Both the drainage tube and the flushing tube are equipped with elastic clamps on the outside. During use, the opening and closing status of the drainage tube and the flushing tube, as well as the degree of opening and closing, are controlled by the elastic clamps according to the usage conditions.
[0016] Furthermore, the collection bag is equipped with an odor-reducing mechanism inside to reduce the odor of excrement. The excrement entering the collection bag comes into contact with multiple breathable mesh covers that are evenly distributed inside. With the help of activated carbon particles inside the breathable mesh covers to adsorb odors, the leakage of odors can be reduced.
[0017] The drainage tube is connected to the collection bag in a relatively sealed manner through external and internal threaded interfaces, further preventing the leakage of odor from the collected excrement. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1: Please refer to Figures 1-7The present invention provides the following technical solution: an integrated anal bag suitable for patients with severe bedridden diarrhea, comprising an anal patch 1 that fits onto the outside of the patient's perianal skin and a centrally located circular hole 2 on the anal patch 1, a guide bag 3 for collecting the patient's excrement connected to the anal patch 1, a guide interface 4 connected through the lower end of the guide bag 3, a drainage tube 5 snapped onto the guide interface 4, and a collection bag 6 for collecting and measuring the patient's excrement connected through the lower end of the drainage tube 5; the guide bag 3 is provided with a flushing mechanism for diluting the excrement inside the guide bag 3 to maintain smooth drainage.
[0028] The collection bag 6 is equipped with an internal threaded interface 8, which is internally connected to an external threaded interface 9. The external threaded interface 9 is fixedly connected to the bottom of the drainage tube 5. The collection bag 6 is equipped with a hanging rope 7 for self-supporting hanging and placement.
[0029] The rinsing mechanism includes a rinsing port 10 installed obliquely on the lower side of the guide bag 3, and a rinsing pipe 11 is connected through the rinsing port 10.
[0030] Both the flushing pipe 11 and the drainage pipe 5 are flexible tubes, and the flushing pipe 11 and the drainage pipe 5 are externally fitted with elastic clamps 12 to limit the size of the pipe's inner diameter opening. The elastic clamps 12 are equipped with limiting teeth 13 to limit the tightening range.
[0031] The anal patch 1 is designed with a soft and elastic ring structure that can closely fit the patient's perianal skin. The inner side of the connecting part is made of skin-friendly and hypoallergenic medical adhesive to ensure that it can be firmly fixed to the perianal area without damaging the patient's skin and to prevent leakage of excrement. The patient's excrement enters the guide bag 3 through the round hole 2 on the surface of the anal patch 1. The excrement inside the guide bag 3 enters the collection bag 6 below through the drainage tube 5 to complete the collection of excrement. The collection bag 6 is made of soft, transparent and somewhat tough medical silicone material. The transparent design makes it easy to observe the amount and characteristics of excrement. The capacity is designed to be 500-1000 ml to meet the potentially larger excretion volume of critically ill patients. At the same time, clear scales are marked on the bag to facilitate accurate recording by medical staff.
[0032] When the excrement collected inside the guide bag 3 is viscous and difficult to drain, flushing fluid is added into the guide bag 3 through the flushing pipe 11. The flushing fluid can dilute the viscous excrement and help drain it out.
[0033] Furthermore, both the drainage tube 5 and the flushing tube 11 are equipped with elastic clamps 12. The elastic clamps 12 can restrict the opening and closing states of the drainage tube 5 and the flushing tube 11, and can also limit the degree of engagement of the drainage tube 5, while also preventing backflow.
[0034] Example 2: Based on Example 1, a deodorization mechanism is also disclosed, the specific structure of which is as follows: The collection bag 6 is equipped with a deodorization mechanism to reduce the odor of excrement. The deodorization mechanism includes multiple breathable mesh covers 14 connected at equal intervals inside the collection bag 6. The breathable mesh covers 14 are curved and connected to the front and rear inner walls of the collection bag 6; activated carbon particles 15 for absorbing the odor of excrement are provided in the breathable mesh covers 14.
[0035] The drainage tube 5 is threaded to the collection bag 6 via an external threaded interface 9 and an internal threaded interface 8. The connection structure is stable and has good sealing performance, which can prevent gas from leaking out of the collection bag 6. The excrement entering the collection bag 6 is in uniform contact with multiple breathable mesh covers 14 that are evenly distributed inside. The activated carbon particles 15 set in the breathable mesh cover 14 can effectively absorb the odor of the excrement, further preventing the odor from leaking out and affecting the user experience.
