Description

Technical Field

[0001] This utility model relates to the field of stoma care, specifically a stoma plug for monitoring sigmoid colon peristalsis. Background Technology

[0002] Sigmoid colostomy is a common surgical procedure used in cases of rectal trauma, obstruction or stenosis, and rectal cancer. Depending on the needs, a sigmoid colostomy may be a temporary or permanent colostomy to facilitate postoperative bowel management. Because the stoma is located in the lower part of the colon, close to the rectum, the excrement has already undergone most of the colonic absorption process, and the excrement from a sigmoid colostomy is usually formed stool. Currently, most patients who have undergone sigmoid colostomy require long-term use of an ostomy bag, which can negatively impact their daily lives, such as reduced comfort, limited social activities, and skin complications.

[0003] In addition, some patients who have undergone sigmoid colostomy are prone to sigmoid colostomy prolapse, which is characterized by the entire intestinal wall protruding through the stoma. Utility Model Content

[0017] 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.

[0018] As attached Figure 1 As shown, the sigmoid colon peristalsis monitoring stoma plug involved in this utility model includes a stoma support plug 1, a plug cap 2, a proximal monitoring ring assembly 3, and an external monitoring assembly 4.

[0019] The stoma support plug 1 includes a support tube 11 and an adhesive plate 12.

[0020] The support tube 11 includes an upper tube and a lower tube. The upper tube is made of polypropylene (PP) or polytetrafluoroethylene (PTFE), which is relatively hard, while the lower tube is made of silicone or other elastic materials, which are relatively soft.

[0021] The adhesive plate 12 is located on the outer side of the lower part of the upper tube of the support tube 11 and is used to adhere the stoma support plug 1 to the skin.

[0022] The lower part of the support tube 11 is provided with a protruding structure 111 to improve the stability of the connection with the intestine. The protruding structure 1111 protrudes outward relative to the outer side of the support tube 11 and is integrally formed during the forming process of the support tube 11.

[0023] A first electrode d1 is provided on the lower outer side of the support tube 11.

[0024] The cap 2 is detachably connected to the upper part of the support tube 11, and can be connected by threads or snap-fit ​​structure.

[0025] The proximal monitoring ring assembly 3 includes a second electrode d2 and a proximal support ring 31, with the second electrode d2 disposed outside the proximal support ring 31.

[0026] The wires of the second electrode d2 extend to the area of ​​the support tube 11, and the wires of the first electrode d1 extend to the outside of the adhesive plate 12 along the support tube 11. The first circuit interface structure 121 is provided on the adhesive plate 12.

[0027] The external monitoring component 4 is used to obtain and process the signals from the first electrode d1 and the second electrode d2. It includes a main unit 41 and a second circuit interface structure 42, which are connected to the main unit 41 via a circuit. The main unit 41 includes modules such as a housing, integrated circuit, and power supply, and is used to receive and process the signals from the first electrode d1 and the second electrode d2.

[0028] The first circuit interface structure 121 and the second circuit interface structure 42 can be common round hole connector structures, or as shown in the attached figure. Figure 1 , 2 The magnetic connector shown is attached. Figure 1 , 2 The first electrode d1 includes a first interface housing d11 and circuit contacts (not shown in the figure); the second electrode d2 includes a second interface housing d21 and circuit contacts (not shown in the figure).

[0029] The first interface shell d11 is rectangular, and the second interface shell d21 has a cross-section of C, which includes a rectangular base plate at the top and side plates on both sides of the rectangular base plate. The distance between the two side plates is the same as the width of the first interface shell d11. In use, the two side plates of the second interface shell d21 cover the outside of the first interface shell d11 and achieve a good connection with the strong magnet. At the same time, they can be detached when subjected to a large external force to avoid being pulled.

[0030] As attached Figure 2 As shown, this application provides a plug cover 2 with a breathable function, including a plug cover base 21, a filter block 22, and a top cover 23.

[0031] The cap base 21 is generally cap-shaped and is detachably connected to the upper part of the support tube 11 via a threaded or snap-fit ​​structure. A concave blind tube 211 is provided in the center of the top surface of the cap base 21, and a vent hole k1 is provided at the bottom of the concave blind tube. The filter block 22 is disposed inside the concave blind tube 211. The upper cover 23 is detachably connected to the upper part of the concave blind tube 211 via a threaded or snap-fit ​​structure to prevent the filter block 22 from leaking out. This structure enables filtration of the exhaust gas, reducing odors.

[0032] To reduce the thickness of the cap 2 and minimize its impact on the user, the upper part of the top cover 23 is basically flush with the upper part of the cap base 21. To facilitate the disassembly of the top cover 23 during filter block 22 replacement, the top cover 23 includes a base plate 231 and a side wall 232 located on the outer side of the base plate. The side wall 232 includes an annular portion a and a filling portion b. The filling portion b is connected to the annular portion a on one side, and a thin sheet-like tension band c is provided on the other side. The bottom of the base plate 231 has ventilation holes. The filling portion b can form an irregular shape within the annular portion a, making it easy to insert fingers to twist and separate or install the top cover 23. The tension band c can assist in applying force.

[0033] An array of notches 212 are provided on the outer side of the plug base 21 to assist in applying force when the plug base 21 is connected.

[0034] The proximal support ring 31 can be an elastic ring structure with an outer diameter larger than that of the intestine to improve the electrode detection effect. During placement, the doctor compresses the proximal support ring 31 with a tool or fingers to insert it into the intestine. After releasing, the proximal support ring 31 returns to its original shape, thus achieving placement within the intestine.

[0035] This application provides a specific structure of a proximal support ring 31, as shown in the attached figure. Figure 3 As shown, the proximal support ring 31 includes a deformation support frame 311 and several outer latex rings 312. The deformation support frame 311 is obtained by bending an elastic material, as detailed in the attached figure. Figure 3 The device shown is made by repeatedly bending an elastic material to a predetermined length and connecting the ends together. It includes a rod-shaped portion x1 and a bent portion x2. The bent portion x2 has a certain degree of elasticity, and the deformable support frame 311 can be unfolded by stretching. To improve the convenience of the setup and removal process, the outer diameter of the deformable support frame 311 after unfolding is larger than the size of the intestine. During removal, the doctor inserts a tool or finger between the intestine and the proximal support ring 31, compresses the proximal support ring 31, and then removes it.

[0036] The latex ring 312 is disposed on the outside of the deformation support frame 311, attached to Figure 3 In the figure, there are two latex rings 312, or there may be multiple latex rings 312 connected to several rod-shaped parts x1. Specifically, in the figure, the latex rings 312 are connected to a rod-shaped part x1 every 120 degrees.

[0037] The latex ring 312 has good deformation capability. During the expansion process of the deformation support 311, the latex ring 312 is also expanded, allowing the electrode to come into contact with the intestine. The second electrode d2 is located on the outside of the latex ring 312.

[0038] To illustrate the various components, see the attached document. Figure 3 The deformation support frame 311 is in a compressed state, and the latex ring 312 is in a partially stretched state. In practice, when the deformation support frame 311 is in a compressed state, the latex ring 312 is also in a contracted state.

[0039] Generally, the distance between the proximal monitoring ring assembly 3 and the stoma support plug 1 is 5-10 cm, and the width of the proximal support ring 31 is 1-3 cm. The width of the latex ring 312 can be smaller than that of the deformation support frame 311.

[0040] The installation can be easily achieved by setting the deformable support frame 311 and the external latex ring 312, and the external latex ring 312 can improve the firmness of the deformable support frame 311 in connection with the intestine.

[0041] The specific methods for acquiring and processing monitoring data are not the subject of this application, but are described below. In practice, the applicant selects a silver / silver chloride electrode (Ag / AgCl) to measure intestinal impedance to obtain information about intestinal peristalsis. The technical approach involves injecting an alternating current of known frequency into one electrode, while the other electrode is used to measure voltage. By measuring the voltage and the known current, the impedance between the two electrodes can be calculated. The movement of intestinal contents causes changes in impedance. The measured impedance changes are then converted into digital signals and further processed, including amplification and filtering, or other methods may be used.

[0042] It should be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
