Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to an external magnetic ostomy device. Background Technology

[0002] Enterostomy is a common surgical procedure, especially in the treatment of diseases such as colon cancer and rectal cancer, or related surgeries. After surgically removing the diseased part of the intestine, an opening is created in the patient's abdomen, and a portion of the intestine is sutured to the abdominal wall, forming a passage called a stoma to help eliminate waste. Current stoma care devices typically use ostomy bags, which are attached to the outside of the stoma to collect the patient's feces and other excrement.

[0003] However, existing ostomy bags have many drawbacks, primarily in their contact with and fixation methods around the stoma. Firstly, because the ostomy bag is in direct contact with the patient's skin for extended periods, the stoma area is subjected to prolonged infiltrative damage and chemical irritation from the bag, leading to discomfort such as redness, exudation, and pain. This is one of the most common complications after stoma surgery, and in severe cases, it can affect the healing of the skin around the stoma. Secondly, prolonged irritation from urine and feces at the stoma site can easily cause localized skin thickening, resulting in irregular wart-like protrusions—that is, thickening or abnormal growth of the skin surface—increasing the difficulty of stoma care and exacerbating patient suffering. Furthermore, mechanical damage is also a common problem during ostomy bag use. The skin around the stoma is prone to physical damage such as tearing due to pressure, improper care, or shearing forces applied when removing the stoma baseplate, further aggravating patient suffering. Other easily overlooked drawbacks include the fact that the stoma changes the way defecation is originally done through the anus. Due to the lack of control from the anal sphincter, patients cannot control defecation at the stoma site. Furthermore, the existing ostomy bags have poor adhesive sealing, resulting in odor leakage, and are also bulky. In addition, the existing stoma instruments are difficult to disassemble and clean, and the odor retention also causes a great emotional and psychological burden on patients.

[0004] Therefore, no effective solution has yet been proposed in the existing technology to reduce the occurrence of the above complications and improve the use of stoma care devices. Summary of the Invention

Detailed Implementation

[0036] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0037] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. Unless otherwise defined, the technical or scientific terms used in this application should be understood in their ordinary sense by one of ordinary skill in the art to which this application pertains. The terms "comprising" or "including" and similar words used in this application specification and claims mean that the elements or objects preceding "comprising" or "including" cover the elements or objects listed following "comprising" or "including" and their equivalents, and do not exclude other elements or objects. The terms "connected" or "linked" and similar words are not limited to physical or mechanical connections and can include electrical connections, whether direct or indirect.

[0038] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items. Specific implementation examples:

[0040] like Figure 1-6 As shown, after preoperative preparation, the surgeon selects a suitable location on the abdomen, makes an incision in the skin and subcutaneous tissue to expose the intestine 3 requiring a stoma, and pulls a portion of the intestine 3 out of the abdomen to form an opening. A pre-selected magnetic ring 1 is then placed around the base of the intestinal 3 outside the body. The intestinal opening is then folded over to cover the magnetic ring 1, and the skin 4 is sutured to the intestinal opening along its edge to form a stoma. Thus, the magnetic ring 1 is sutured and fixed between the intestinal opening and the skin 4 outside the body, ensuring a stable fit and good adhesion. Subsequently, the patient or caregiver attaches the outer cover 2 to the stoma using magnetic attraction, ensuring a good fit between the outer cover 2 and the magnetic ring 1.

[0041] The magnetic ring 1 is fitted with a silicone sleeve, which comes into direct contact with the intestinal opening and the skin 4. It has good biocompatibility and softness, preventing skin allergies and mechanical damage. The annular pad 201 in the outer cover 2, which contacts the stoma, is also made of silicone, further reducing skin allergies and mechanical damage. During installation and use, the flared section 211 of the annular pad 201 ensures complete coverage of the stoma, and the magnetic ring 1, covered by the intestinal opening, engages with the limiting section 212. Under the magnetic attraction of the magnetic ring 1 and the magnet 202, the annular pad 201 slightly deforms and compresses the stoma, achieving a good seal and reducing odor leakage.

[0042] When the patient excretes, the stoma device is opened and closed via a simple switch operation. This involves the handle 234, which moves the sealing plate 224 within the receiving cavity 235, opening the excretion channel and allowing bodily waste to be discharged through the stoma device. Because the sealing element 206 and the sealing plate 224 are press-fitted, both a sealing function and manual follow-up control are achieved. When there is a large amount of waste, the patient or medical staff can slowly open the sealing plate 224 to prevent waste from spraying out. Furthermore, the base cover 205 of the outer cover 2 can be connected to an external excretion pipeline, and the sealing element 206 ensures the sealing of the pipeline connection. This allows the patient to directly excrete intestinal contents to a specific location, such as a toilet. Compared to ostomy bags, which cannot control the timing of excretion, this invention allows the patient to autonomously select the excretion occasion and timing by controlling the opening and closing valve body 204, thus reducing the patient's psychological burden.

[0043] After use, the outer cover 2 can be removed from the stoma to disinfect and rinse the stoma area and the removable outer cover 2. This is convenient and quick, and can prevent odor from lingering. After cleaning, it can be reinstalled by magnetic adsorption. The operation is simple and suitable for the daily care needs of various patients.

[0044] In addition, the magnetic ring 1 is equipped with a freely rotating magnetic bead 101, so that patients can undergo MRI examinations while wearing the external magnetic ostomy device of the present invention without disassembly or adjustment, ensuring the integrity of the device and the smooth conduct of the examination.
