Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment and relates to a stoma anal dilator. Background Art

[0002] A stoma is a surgical opening created in the abdominal wall for defecation and urination, and is commonly used in the treatment of colorectal and bladder cancer patients. After stoma surgery, to prevent and treat stoma stenosis, dilation is performed depending on the stoma's condition. The most common method is to dilate the stoma with a finger. This involves wearing a glove, applying lubricant, and gently inserting a finger into the stoma to a depth of one to two knuckles. The finger remains in the stoma for 5 to 10 minutes, and dilation is performed once or twice daily.

[0003] Finger dilation requires the finger to remain inside the stoma for 5-10 minutes, which can easily cause arm soreness. Existing techniques have proposed using an anal dilator to dilate the stoma, which avoids this arm soreness. However, using an anal dilator to dilate the stoma, especially when the dilator remains inside the stoma, makes it difficult to collect or clean fecal fluid seeping from the stoma, resulting in fecal contamination and sensory discomfort. Utility Model Content

[0004] The purpose of the utility model is to provide a stoma dilator, which can be used to expand the stoma and collect exudate, so as to solve the problems raised in the above background technology.

[0005] The utility model is achieved through the following technical solutions:

[0006] A stoma anal dilator comprises an anal dilator tube and a syringe, wherein the left end of the anal dilator tube is sheathed with an annular water bag, the inner side wall of the annular water bag is glued and fixed to the outer side wall of the anal dilator tube, the left end of the anal dilator tube and the annular water bag can be inserted into the stoma for dilating the stoma, the right end of the annular water bag is provided with a water injection joint, the interior of the water injection joint is communicated with the interior of the annular water bag, the syringe and the water injection joint are connected by a hose, the syringe is used to inject water into the annular water bag to expand it and to pump out the water in the annular water bag to make it deflate, when the stoma is dilated, the annular water bag is initially deflated, the left end of the anal dilator tube is inserted into the stoma, and the annular water bag is then filled with water. The annular water bag is inserted into the stoma, and then water can be injected into the annular water bag using a syringe to expand the annular water bag to expand the stoma. After staying in the stoma for 5 to 10 minutes, the water in the annular water bag is sucked out to make it deflate, and then the anal dilator is pulled out. When the annular water bag is deflated, it can make it easier to insert it and the anal dilator into the stoma and easier to pull out from the stoma without damaging the stoma. The right end of the anal dilator is connected to a collection bag for collecting fecal liquid. When the left end of the anal dilator tube and the annular water bag stay in the stoma to expand the stoma, the fecal liquid can flow out through the inside of the anal dilator tube and flow into the collection bag for collection, so as to prevent the fecal liquid from leaking out and causing pollution and sensory discomfort.

[0007] Further defined, a limit plate is fixedly provided on the outer side wall of the anal expansion tube at the right end of the annular water bag, which can be limited by the limit plate to prevent the anal expansion tube from being inserted too deeply into the stoma.

[0008] Further definition, the horizontal distance between the left wall of the limit plate and the left end of the anal dilator is 3 to 4 cm, and the left end of the annular water bag protrudes from the left end of the anal dilator by 0.5 to 1.5 cm.

[0009] As a further limitation, the left end of the anal expansion tube is provided with an arc-shaped chamfer to prevent the stoma from being damaged or the annular water bag from being scratched when the anal expansion tube is inserted into the stoma.

[0010] Further definition, the limit plate is provided with a socket for the water injection connector to pass through, so that the interface end of the water injection connector is located on the right side of the limit plate, which is convenient for connecting the syringe and does not cause any obstruction when inserting the anal dilator into the stoma.

[0011] Further defined, a handle is fixedly provided on the top of the limiting plate, and the handle extends in a square shape along the central axis of the limiting plate. The operator can hold the handle by hand to operate and maintain the stability of the anal dilator.

[0012] In a further definition, the anal dilator is a V-shaped curved tube, which is convenient for holding the handle and can prevent the inlet end of the collection bag from being bent and fitted.

[0013] Further defined, the left end of the anal dilator is tapered, and the outer diameter of the left end is smaller than that of the right end, so that the left end is slightly smaller than the right end, which is convenient for insertion into the stoma.

[0014] Further definition, the outer wall of the right end of the anal dilator is integrally formed with a positioning ring, the collection bag is mounted on the positioning ring at the right end of the anal dilator, and the collection bag and the anal dilator are fixed by an elastic rubber ring, which can facilitate the disassembly and assembly of the collection bag. The collection bag is a disposable transparent plastic bag, and the anal dilator can be reused by the same person after cleaning and disinfection.

[0015] Further definition, the anal dilator also includes a hollow circular collection box, the left side wall and the right side wall of the circular collection box are provided with circular through holes that are concentric with the left side wall and communicate with the inside and outside. The diameter of the circular through hole on the left side wall of the circular collection box is 0.2 to 0.4 cm larger than the diameter of the stoma, so that the stoma can pass into the circular collection box. The diameter of the circular through hole on the right side wall of the circular collection box is 1 to 2 cm smaller than the inner diameter of the circular collection box, so that the inside of the circular collection box has a groove. The left outer wall of the circular collection box is fixed with a medical adhesive tape that can be adhered to the skin surface around the stoma. The medical adhesive tape is used to adhere and fix the circular collection box around the stoma, so that the circular collection box is surrounded by the outside of the stoma. The fecal liquid seeping from between the stoma and the anal dilator can drip into the circular collection box for collection.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The anal dilator can be used to dilate a stoma. The annular water bag can be sent into the stoma by using the anal dilator tube. After the left end of the anal dilator tube and the annular water bag are inserted into place, water can be injected into the annular water bag by using a syringe to expand it. The expanded annular water bag can further dilate the stoma. After staying in the stoma for 5 to 10 minutes, the water in the annular water bag is sucked out to make it deflate, and then the anal dilator tube is pulled out. When the annular water bag is deflated, it can be easier to insert it and the anal dilator tube into the stoma and to be pulled out from the stoma without damaging the stoma. During the stoma expansion process, some fecal liquid may flow into the collection bag along the inside of the anal dilator tube for collection, and some fecal liquid may seep out along the gap between the stoma and the annular water bag and drip into the circular collection box. Fecal liquid can be collected during the stoma expansion process to prevent the fecal liquid from spreading everywhere, thereby reducing sensory discomfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example 2

[0041] A stoma anal dilator, which is different from the embodiment 1 in that: the anal dilator further includes a hollow circular collection box 10; Figure 4 and Figure 5 As shown, the left and right walls of the circular collecting box 10 are both provided with circular through holes that are concentric therewith and communicate with each other inside and outside. The diameter of the circular through hole on the left wall of the circular collecting box 10 is 0.3 cm larger than the diameter of the stoma, so that the stoma can pass through the circular collecting box 10. The diameter of the circular through hole on the right wall of the circular collecting box 10 is 1.5 cm smaller than the inner diameter of the circular collecting box 10, so that the inside of the circular collecting box 10 has a groove. The left outer wall of the circular collecting box 10 is fixed with a medical adhesive tape 11 that can be adhered to the skin surface around the stoma. The medical adhesive tape 11 is used to adhere and fix the circular collecting box 10 around the stoma, so that the circular collecting box 10 is surrounded on the outside of the stoma, and the fecal liquid seeping from between the stoma and the anal dilator 1 can drip into the circular collecting box 10 for collection.

[0042] The circular collection box 10 is made of PP plastic, has certain flexibility, and is lightweight. The medical adhesive tape 11 can be a double-sided tape, one side of which is pasted on the left outer wall of the circular collection box 10, and the other side is used to be pasted on the skin surface. In addition, the medical adhesive tape 11 can also be a hydrocolloid chassis on the ostomy bag.

[0043] The working principle and technical effects of the anal dilator in this embodiment are as follows:

[0044] When dilating the stoma, clean the skin around the stoma, stick the medical adhesive tape 11 on the skin surface around the stoma, and extend the stoma into the circular collection box 10 through the circular through hole on the left side wall of the circular collection box 10;

[0045] The annular water bag 3 is initially deflated. Lubricating oil is applied to its outer surface, and its left end is inserted into the left end of the anal expansion tube 1. The operator holds the limit plate 2 and inserts the left end of the anal expansion tube 1 into the stoma. The annular water bag 3 then enters the stoma. After being inserted into place, water is sucked into the syringe 5. The water injection connector 4 is connected to the syringe 5 through the hose 6. Water is injected into the annular water bag 3 through the syringe 5 to expand it. The expanded annular water bag 3 can further expand the stoma. After staying in the stoma for 5 to 10 minutes, the water in the annular water bag 3 is sucked out to make it deflated. Then the anal expansion tube 1 is pulled out. When the annular water bag 3 is deflated, it can be inserted into the stoma more easily and pulled out from the stoma together with the anal expansion tube 1, without damaging the stoma.

[0046] During the stoma expansion process, some fecal liquid may flow into the collection bag 8 along the inside of the anal expansion tube 1 and be collected, and some fecal liquid may seep out along the gap between the stoma and the annular water bag 3 and drip into the circular collection box 10. The fecal liquid can be collected during the stoma expansion process to prevent the fecal liquid from spreading everywhere, which can reduce sensory discomfort.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
