Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fecal collection device. Background Technology

[0002] In the field of medical care, fecal collection bags are essential nursing devices for incontinent patients, patients after intestinal surgery, and people with limited mobility. Currently, most fecal collection devices use adhesive rings or elastic belts to directly fix the bag around the patient's anus. These devices require prolonged contact with the skin to maintain a seal, causing significant inconvenience for patients in daily activities: when patients go for walks or engage in light activity, the bag moves with changes in body position, and the accumulated feces inside create a feeling of pressure due to gravity. Additionally, friction between the bag and clothing can lead to visual exposure, causing psychological distress for the patient. Temporarily removing the bag requires peeling off the tightly adhered device, causing repeated tearing and skin irritation or even damage. Furthermore, the process of cleaning the skin, reattaching the ring, and reconnecting the bag must be repeated before the next bowel movement. This repetitive disassembly and reassembly reduces nursing efficiency and exacerbates patient resistance to the device. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fecal collection device that can remove accumulated feces as needed.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A fecal collection device includes a flexible, strip-shaped collection bag with an insertion tube communicating with the interior of the bag on one side. The insertion tube has an expandable anti-dislodgement ring at its end for insertion into a patient's anus and securing it to the anal wall. An adhesive layer is provided around the insertion tube to adhere to the patient's anal skin. At least two sets of sealing strips are spaced apart along the length of the bag, horizontally extending through both sides. Initially, the sealing strips are open to allow communication within the bag. When segmented sealing is required, the lower segment containing accumulated feces is separated by closing two adjacent sealing strips at the target location and cutting the bag between the two strips.

[0006] Compared to existing technologies, this invention achieves at least the following beneficial effects: Through its segmented cutting design with a sealing strip, this invention only requires cutting the lower segment of the bag filled with feces, eliminating the need to remove the insertion tube and adhesive layer. The upper segment remains sealed due to the closed sealing strip and can continue to be used, effectively reducing physical friction and chemical irritation to the perianal skin from repeated disassembly and reassembly of the fixing device, thus lowering the risk of dermatitis. Simultaneously, the horizontally spaced sealing strips allow patients to seal the segment containing feces before cutting it. The remaining bag, due to its reduced volume and seal, significantly reduces the feeling of heaviness and friction noise during walking, making it lighter and more discreet for patients to go out, effectively reducing psychological resistance.

However, it should be understood that the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of the present invention more complete and to fully convey the concept of the present invention to those skilled in the art.

Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0015] like Figures 1 to 4 As shown, in at least one embodiment of the fecal collection device of this utility model, a flexible strip-shaped collection bag 1 is included. An insertion tube 2, communicating with the interior of the collection bag 1, is provided on one side. An expandable anti-dislodgement ring 3 is provided at the end of the insertion tube 2 for insertion into the patient's anus and for securing the anal wall with the anti-dislodgement ring 3. An adhesive layer 4 is provided around the insertion tube 2 in the collection bag 1 to adhere to the skin around the patient's anus. At least two sets of sealing strips 5 are spaced apart along the length of the bag body, with the sealing strips 5 horizontally penetrating both sides of the bag body. The sealing strips 5 are initially open to allow communication within the collection bag 1. When segmented sealing is required, the lower segment of the bag containing accumulated feces is separated by closing two adjacent sealing strips 5 at the target location and cutting the bag body between the two sealing strips 5.

[0016] In this embodiment, the anti-detachment ring 3 of the insertion tube 2 works in conjunction with the adhesive layer 4 to ensure the device fits firmly to the anus and prevents it from falling off. The spaced-out sealing strips 5 allow the pre-filled bag segment to be cut off, retaining the upper segment for continued use, avoiding repeated disassembly and reassembly. Feces can be cleaned without completely removing the device, reducing skin friction and chemical irritation, and improving ease of use.

[0017] refer to Figure 2 Specifically, the anti-dislodgement ring 3 is an inflatable ring-shaped airbag, which is connected to an external inflation control device via a miniature air pump 6. After inflation, it expands to press against the inner wall of the anus. With this design, the inflation degree of the airbag can be adjusted to adapt to different patients' anal sizes, improving fixation comfort.

[0018] The adhesive layer 4 is made of medical-grade pressure-sensitive adhesive and is covered with a peelable protective film 7. The protective film 7 is removed before installation to expose the adhesive layer 4. This design using medical-grade pressure-sensitive adhesive effectively reduces the risk of skin allergies and provides a gentler fit; at the same time, the protective film 7 ensures that the adhesive layer 4 is sterile before use, effectively reducing the risk of infection.

[0019] refer to Figure 2 Specifically, the sealing strip 5 is a self-sealing structure, including matching protrusions 51 and grooves 52. A seal is achieved by pressing the protrusions 51 into the grooves 52. This design allows for quick operation by patients or caregivers without the need for additional tools.

[0020] The top of the collection bag 1 is equipped with a one-way exhaust valve 8, which is used to expel gas from the bag and prevent liquid backflow. With this setting, gas can be expelled from the bag, avoiding the feeling of pressure or visual embarrassment caused by the expansion of the bag.

[0021] The fecal collection device is used as follows: During installation, after removing the protective film 7 of the adhesive layer 4, insert the anti-slip ring 3 at the end of the insertion tube 2 into the anus. Then, inflate and secure it using the micro air pump 6. Next, adhere the adhesive layer 4 to the perianal skin to ensure a firm fit. During use, keep the sealing strip 5 open to collect feces, and expel the air from the bag through the one-way exhaust valve 8 at the top. When going out or cleaning accumulated feces, press the two adjacent sets of sealing strips 5 above the feces to seal it. Cut the bag between the two sets of sealing strips 5 to remove the lower section of feces; the upper section of the bag can still be used due to the seal. For replacement, first deflate the anti-slip ring 3 and gently remove the device. After cleaning the skin, a new collection bag 1 can be installed. The entire process, through segmented sealing and cutting design, avoids repeated disassembly and reassembly of the device, reducing skin irritation, while ensuring sealing and portability, making it suitable for patients' daily activities or long-term care scenarios.

[0022] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this utility model should be within the protection scope of this utility model.
