Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically to an anal bag for colonoscopy. Background Technology
[0002] Colonoscopy is an important tool for the diagnosis and treatment of digestive system diseases. It allows doctors to directly observe the inside of the colon and rectum to detect polyps, tumors, or other abnormalities. However, during colonoscopy, poor bowel preparation, excessive water intake after taking laxatives, or a large amount of fluid accumulation in the intestinal lumen due to physiological or pathological factors can lead to overflow of fecal matter from the anus. This not only contaminates the patient's skin and surrounding environment, creating a susceptible environment for infection and affecting the patient's health, but also hinders the operator's normal operation. The operator needs to repeatedly wipe away the overflowing fecal matter from the anus, which not only increases the complexity of the procedure but may also affect the efficiency and effectiveness of the colonoscopy. Utility Model Content
[0003] The purpose of this invention is to design an anal bag for collecting fecal matter during colonoscopy, reducing environmental pollution and simplifying the operator's procedures.
[0004] To achieve the above objectives, this utility model provides an anal bag for colonoscopy, comprising a rectal segment bag body and a storage bag body. The distal end of the rectal segment bag body has an annular opening, and the proximal end of the rectal segment bag body is connected to the opening of the storage bag body.
[0005] The rectal segment pouch is provided with an elastic ring and a through hole. The elastic ring is connected to the annular opening. The inner diameter of the elastic ring limits the size of the annular opening. When the elastic ring is opened, it can be fixed to the inner wall of the rectum. The through hole is opened at the proximal end of the rectal segment pouch for insertion of a colonoscope.
[0006] In use, the elastic ring and at least part of the rectal segment bag are located inside the rectum, while the through hole and the storage bag are exposed outside the patient's body.
[0007] Furthermore, the outer diameter of the elastic ring is larger than the inner diameter of the rectum.
[0008] Furthermore, the surface of the elastic ring is provided with several textured structures to increase the friction with the inner wall of the rectum.
[0009] Furthermore, the texture structure includes at least one of bumps, protrusions, and ripples.
[0010] Furthermore, an elastic sealing ring is provided circumferentially in the through hole, and when the colonoscope is inserted, the elastic sealing ring abuts against the surface of the colonoscope.
[0011] Furthermore, the inner diameter of the elastic sealing ring is smaller than the outer diameter of the colonoscope.
[0012] Furthermore, the length of the rectal segment pouch is greater than the axial length of the anal canal.
[0013] Furthermore, the surface of the opening of the storage bag is provided with several adhesive parts, which are used to adhere and fix the side of the opening of the storage bag away from the through hole to the skin surface of the patient's buttocks when the patient is in a lateral position.
[0014] Compared with the prior art, the beneficial effects of this utility model include at least the following:
[0015] The anal bag of this utility model includes a rectal segment bag body and a storage bag body; wherein, the distal end of the rectal segment bag body is connected to an elastic ring, which is inserted into the patient's rectum by contracting and inserting it, and then naturally opens in the rectum after being released, thereby allowing the elastic ring to expand and fix itself to the inner wall of the rectum, so that fecal matter can pass through the rectal segment bag body directly into the storage bag body outside the patient's body, reducing environmental pollution; the proximal end of the rectal segment bag body includes a through hole located outside the patient's body, which facilitates the insertion of a colonoscope for examination.
[0016] Furthermore, the surface of the elastic ring of this invention is provided with several textured structures to increase the friction with the rectal wall, which helps to stably fix the elastic ring and ensures that the anal bag will not dislodge from the patient's body. The surface of the opening of the storage bag includes several adhesive parts, which can be used to adhere and fix the side of the opening of the storage bag away from the through hole to the patient's buttock skin surface, further fixing the position of the anal bag and preventing the anal bag from slipping off.

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] In this article, "proximal" refers to the direction closer to the operator, and "distal" refers to the direction closer to the patient's body cavity.
[0030] The term "anal canal" as used in this article refers to the short tube connecting the "rectum" and the "anus".
[0031] The "anal sphincter" mentioned in this article refers to the muscles surrounding the anal canal, which have the ability to naturally contract the anal canal and anus.
[0032] As described in the background section, during colonoscopy, patients often experience poor bowel preparation or excessive water intake after taking laxatives, leading to a large accumulation of fluid in the intestinal lumen. This results in the anus overflowing with fecal matter during the colonoscopy, contaminating the patient's skin and the surrounding environment, affecting the patient's health and the operator's work.
[0033] To address the aforementioned problems, this invention provides an anal bag for colonoscopy (hereinafter referred to as "anal bag"). The anal bag is used during colonoscopy. An elastic ring is positioned at the distal end of the rectal segment of the bag. By compressing the elastic ring with a finger, the ring and at least a portion of the rectal segment are inserted into the rectum through the anus. Upon releasing the elastic ring, it generates elastic tension as it returns to its original shape, gradually expanding to the mucosal surface of the rectal wall. Because the outer diameter of the elastic ring is larger than the inner diameter of the rectum, the expanded elastic ring exerts a certain radial pressure on the rectal wall, allowing it to be held in place. Fecal matter in the intestinal lumen can then flow sequentially through the ring cavity of the elastic ring and the inner wall of the rectal segment into the storage bag, thus preventing fecal matter from contaminating the patient's skin and the surrounding medical environment.
[0034] The following description, in conjunction with the accompanying drawings, illustrates an anal bag for colonoscopy provided by this utility model.
[0035] like Figure 1 As shown, the anal bag provided by this utility model includes a rectal segment bag body 10 and a storage bag body 20. The distal end of the rectal segment bag body 10 is an annular opening, and the proximal end of the rectal segment bag body 10 is connected to the opening of the storage bag body 20.
[0036] The annular opening of the rectal pouch 10 is provided with an elastic ring 11, the inner diameter of which defines the size of the annular opening. When the elastic ring 11 is subjected to force, it contracts, facilitating the operator to push the elastic ring 10 and at least part of the rectal pouch 10 into the patient's rectum 30 using their fingers. When the operator releases their fingers, the elastic ring 10 tends to return to its original shape, expanding and fixing itself to the mucosal surface of the inner wall of the rectum 30. This allows fecal matter in the intestinal lumen to flow through the annular cavity of the elastic ring 10 along the inner wall of the rectal pouch 10 into the storage pouch 20 without overflowing onto the patient's skin surface and interfering with the colonoscopy. The anal canal 60 is surrounded by the anal sphincter 50. The natural contraction of the anal sphincter 50 helps to keep the elastic ring 11 and part of the rectal pouch 10 within the rectum 30, thereby reducing the risk of accidental dislodgement of the elastic ring 11.
[0037] In some embodiments, the outer diameter of the elastic ring 11 is slightly larger than the inner diameter of the patient's rectum 30, so that when the elastic ring 11 is stretched, a certain radial pressure is generated between the surface of the elastic ring 11 and the inner wall of the rectum 30, so that the elastic ring 11 can fit tightly against and be fixed to the inner wall of the rectum 30, preventing the anal bag from falling off.
[0038] In some embodiments, the surface of the elastic ring 11 is provided with several textured structures (not shown in the figure). The textured structures include, but are not limited to, protrusions, bumps, and ripples. When the elastic ring 11 is opened, the textured structures can increase the friction between the surface of the elastic ring 11 and the inner wall of the rectum 30, thereby making it more conducive to the surface of the elastic ring 11 being fixed to the inner wall of the rectum 30.
[0039] In some embodiments, the elastic ring 11 may be made of silicone or rubber, which has excellent elasticity and can make safe contact with human tissue.
[0040] The rectal pouch 10 has a through-hole 12 at its proximal end for insertion of a colonoscope. In some embodiments, an elastic sealing ring 121 is provided circumferentially around the through-hole 12. The inner diameter of the elastic sealing ring 121 is slightly smaller than the outer diameter of the colonoscope. When the colonoscope is inserted into the rectal pouch 10 through the elastic sealing ring 121, the elastic sealing ring 121 can abut against the surface of the colonoscope, forming a seal to prevent fecal matter from leaking along the colonoscope through the through-hole 12. The inner wall of the rectal pouch 10 is coated with a water-based super-lubricating material coating, such as a polytetrafluoroethylene coating, so that after the colonoscope is inserted through the through-hole 12, even if it comes into contact with the inner wall of the rectal pouch 10, it can smoothly slide into the rectum 30 distally along the inner wall of the rectal pouch, thus eliminating the need for repeated use of colonoscope lubricant on the colonoscope surface and improving the efficiency of colonoscopy.
[0041] During colonoscopy, the elastic ring 11 and at least a portion of the rectal pouch 10 are located within the rectum 30, while the through-hole 12 and the storage pouch 20 are exposed outside the patient's body. In some embodiments, the length of the rectal pouch 10 is greater than the axial length of the anal canal 60, ensuring that the elastic ring 11 can be pushed in and secured within the rectum 30. During colonoscopy, the patient is typically in a lateral decubitus position, and the proximal end of the storage pouch 20 can be placed on the examination bed near the patient's buttocks to support the storage pouch 20, preventing the anal pouch from dislodging from the patient's anus due to the gravity of fecal matter.
[0042] In some embodiments, the surface of the opening of the storage bag 20 is provided with several adhesive portions (not shown in the figure). As an example, rice starch adhesive can be coated on the surface of the opening of the storage bag 20. When the patient is in a lateral decubitus position, it is used to adhere and fix the side of the opening of the storage bag 20 away from the through hole 12 to the skin surface of the patient's buttocks, further fixing the position of the anal bag, while ensuring that the through hole 12 is exposed in the operator's field of vision, which facilitates colonoscopy insertion.
[0043] The method of using this utility model includes the following steps:
[0044] Step 1: The operator uses their fingers to contract the elastic ring at the distal end of the rectal segment of the anal bag, pushing the elastic ring and at least part of the rectal segment into the patient's rectum through the anus. The through-hole at the proximal end of the rectal segment and the storage bag are exposed outside the patient's body. The proximal end of the storage bag is placed on the examination bed near the patient's buttocks.
[0045] Step 2: The operator releases and removes the finger from inside the patient's rectum, and by evenly pulling the proximal end of the rectal segment bag, causes the elastic ring to expand rapidly, thereby fixing it to the inner wall of the rectum.
[0046] Step 3: With the through-hole outside the patient exposed to the operator's view, the operator glues and fixes the side of the storage bag opening away from the through-hole to the patient's buttocks to further secure the position of the anal bag.
[0047] Step 4: The operator inserts the colonoscope into the rectal pouch through the through-hole and pushes it distally, allowing the colonoscope to enter the patient's rectum through the annular opening at the distal end of the rectal pouch along the inner wall or cavity of the rectal pouch for subsequent colonoscopy.
[0048] In summary, the anal bag design of this utility model includes a rectal segment bag body and a storage bag body. The distal end of the rectal segment bag body is connected to an elastic ring, which can be inserted into the patient's rectum upon contraction and naturally opens upon release, expanding and fixing itself to the rectal wall. The proximal end of the rectal segment bag body has a through hole with an elastic sealing ring circumferentially arranged for colonoscope insertion. This design allows fecal matter to flow directly from the rectal segment bag body into the external storage bag body, preventing fecal matter overflow, effectively reducing environmental pollution, and improving the efficiency of colonoscopy.

Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above content. Therefore, the scope of protection of the present invention should be defined by the appended claims.
