Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a temporary stoma closure device. Background Technology

[0002] A stoma is caused by a disease of the digestive or urinary system and requires surgical treatment to separate the intestinal tract and bring one end of the intestinal tract out to the body surface (the anus or urethra is moved to the abdominal wall) to form an opening.

[0003] Generally, patients need to have their ostomy bags changed regularly to maintain personal hygiene and detect potential problems such as skin redness, pain, and abnormal discharge. When changing the ostomy bag, the skin around the stoma needs to be cleaned with warm water or saline solution to remove dirt and secretions. However, it's important to note that because the stoma is open and most patients cannot control their bowel movements, there may be a continuous and intermittent discharge of fecal matter and other intestinal contents during cleaning. This requires healthcare workers to wipe the patient's skin as quickly as possible to avoid repeated wiping after the discharge. Currently, in clinical practice, healthcare workers temporarily seal the stoma with cotton balls or sealing plugs to prevent the discharge of intestinal contents during cleaning. However, this method has the following drawbacks:

[0004] 1. Because the sealing plug and temporary sealing devices such as cotton lack fixing components at both ends, if medical staff accidentally touch them during cleaning or the patient moves during cleaning, they can easily fall outwards, affecting their sealing effect. They may also move inwards and fall into the patient's intestines, greatly reducing the safety of patient use. The connection between them and the patient's stoma is also unstable.

[0005] 2. During the cleaning process, due to the sealing of the cotton and the sealing plug, fecal matter and other intestinal contents accumulate in the patient's intestines. When medical staff wipe the patient's skin and install a new stoma base plate, and need to remove the cotton or sealing plug, the intestinal contents accumulated in the patient's intestines flow out rapidly. Since the stoma base plate has been installed but the ostomy bag has not, the intestinal contents drip onto the patient's body, bottom, etc., which increases the workload of medical staff in subsequent cleaning and reduces the patient's comfort.

[0006] Therefore, how to design a temporary stoma closure device that can solve the above-mentioned technical problems is a technical problem that needs to be solved. Utility Model Content

[0007] To address the aforementioned problems, the present invention aims to provide a temporary stoma sealing device that solves the issues of poor connection stability between the existing temporary stoma sealing device and the stoma fitting, and easy leakage of intestinal contents when the device is removed.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: It includes a sealing column for sealing the stoma, a first airbag fixed to the outer peripheral wall of the bottom of the sealing column, a second airbag fixed above the first airbag on the outer peripheral wall of the sealing column, a connecting block movably disposed above the second airbag on the outer peripheral wall of the sealing column, a connecting shell fixed to the outer peripheral wall of the connecting block, and a waterproof plastic membrane movably disposed inside the connecting shell, one end of which is fixedly connected to the outer peripheral wall of the connecting block, and the other end of which passes through the connecting shell and is disposed outside the connecting shell; a first adhesive layer is fixed to the inner peripheral wall of the movable end of the waterproof plastic membrane; the outer diameter of the first airbag after expansion ranges from 2 to 5.5 cm;

[0009] The sealing column is fixedly provided with a first connecting tube communicating with the first airbag, and a first through hole communicating with the first connecting tube is opened on the top end face of the sealing column; a second connecting tube communicating with the second airbag is also opened in the sealing column, and a second through hole communicating with the second connecting tube is opened on the top end face of the sealing column; a sealing plug is fixedly provided in both the first through hole and the second through hole;

[0010] The sealing column has an external thread fixed on its outer peripheral wall along its height direction. The connecting block includes a connecting inner tube movably disposed on the outer peripheral wall of the sealing column and a connecting outer abutment block in the shape of a hollow frustum slidably disposed on the outer peripheral wall of the connecting inner tube. The connecting inner tube has an internal thread that mates with the external thread, and the connecting inner tube is threadedly connected to the outer peripheral wall of the sealing column. A second adhesive layer is fixed on the outer edge of the bottom surface of the connecting outer abutment block. The diameter of the bottom surface of the connecting outer abutment block is in the range of 2-5.5 cm.

[0011] Furthermore, symmetrical sliding tracks are provided on the left and right sides of the inner peripheral wall of the connecting outer abutment block along its height direction, and a slider is fixed at the bottom of the outer peripheral wall of the connecting inner tube corresponding to the positions of the left and right sliding tracks, and the slider is slidably disposed in the sliding track.

[0012] Furthermore, a limiting flange is fixedly provided at the outer end of each of the left and right sliders, and several limiting grooves are provided at equal intervals along the height direction of the slide rails on both sides for cooperating with the limiting flange.

[0013] Furthermore, the bottom surfaces of both the first adhesive layer and the second adhesive layer are covered with dustproof paper.

[0014] Furthermore, the waterproof plastic film is folded and placed inside the connecting housing.

[0015] Furthermore, the sealing column is 10-15cm long, and the second airbag is 3-5cm long.

[0016] This utility model has the following beneficial effects:

[0017] 1-This utility model is provided with a first airbag and a connecting outer abutment block; when in use, the first airbag is inflated or filled with water and then abuts against the inner wall of the stoma, and the connecting outer abutment block is moved so that it abuts against the patient's abdomen to fix the position of the sealing column, so as to prevent the sealing column from moving inward or outward due to the patient moving or medical staff accidentally touching it during the cleaning process, thereby improving the safety of use.

[0018] 2- This utility model is equipped with a second airbag and a first airbag. When in use, the first airbag and the second airbag are inflated or filled with water to expand, so that they respectively abut against the inner side wall of the stoma and the inner wall of the stoma to seal the stoma. Compared with a single airbag, sealing plug and cotton to seal the stoma, it effectively improves the sealing effect and further prevents secretions from flowing out during the cleaning process.

[0019] 3- This utility model is designed with a connecting shell and a waterproof plastic film. After cleaning the patient's abdominal skin, the waterproof plastic film is connected to the new stoma base plate, so that the stoma base plate, the sealing column and the waterproof plastic film form a relatively sealed space. This facilitates the collection of fecal matter that has accumulated in the patient's body during the cleaning process and will flow out after the sealing plug is removed. It also avoids the outflow of fecal matter and other intestinal secretions after the single air bag, sealing plug and cotton are removed, which would affect the patient and cause discomfort.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0035] See Figure 1-6 As shown, the solution includes a sealing column 1 for sealing the stoma, a first airbag 2 fixed to the outer peripheral wall of the bottom of the sealing column 1, a second airbag 3 fixed above the first airbag 2 on the outer peripheral wall of the sealing column 1, a connecting block 4 movably disposed above the second airbag 3 on the outer peripheral wall of the sealing column 1, a connecting shell 5 fixed to the outer peripheral wall of the connecting block 4, and a waterproof plastic membrane 6 movably disposed inside the connecting shell 5, one end of which is fixedly connected to the outer peripheral wall of the connecting block 4 and the other end of which passes through the connecting shell 5 and is disposed outside the connecting shell 5; a first adhesive layer is fixed to the inner peripheral wall of the movable end of the waterproof plastic membrane 6; furthermore, depending on the size and type of the stoma, in this embodiment, the outer diameter of the first airbag 2 after expansion is set to be in the range of 2-5.5cm;

[0036] The sealing column 1 is fixedly provided with a first connecting pipe 11 that communicates with the first airbag 2, and a first through hole 12 that communicates with the first connecting pipe 11 is opened on the top end face of the sealing column 1; a second connecting pipe 142 that communicates with the second airbag 3 is also opened in the sealing column 1, and a second through hole that communicates with the second connecting pipe 142 is opened on the top end face of the sealing column 1; a sealing plug 121 is fixedly provided in both the first through hole 12 and the second through hole;

[0037] The sealing column 1 has an external thread 15 fixed on its outer peripheral wall along its height direction. The connecting block 4 includes a connecting inner tube 41 movably disposed on the outer peripheral wall of the sealing column 1 and a connecting outer abutment 42 in the shape of a hollow frustum slidably disposed on the outer peripheral wall of the connecting inner tube 41. The inner peripheral wall of the connecting inner tube 41 has an internal thread 411 that mates with the external thread 15, and the connecting inner tube 41 is threadedly connected to the outer peripheral wall of the sealing column 1. A second adhesive layer 421 is fixed on the outer edge of the bottom surface of the connecting outer abutment 42. Preferably, a limiting post that mates with the connecting inner tube 41 is provided on the outer peripheral wall of the sealing column 1 at the position corresponding to the lowest point of the external thread 15.

[0038] Furthermore, the bottom diameter of the connecting outer abutment block 42 ranges from 2 to 5.5 cm. Generally, the diameter of the sigmoid colon is approximately 3-5 cm; the diameter of the ileostomy is approximately 2-2.5 cm; and the diameter of the urethrostomy is approximately 2-2.5 cm. Different connecting outer abutment blocks 42 with different bottom diameters are selected according to different types of ostomies, ensuring that the bottom diameter of the connecting outer abutment block 42 is larger than the ostomy opening. Furthermore, since the sigmoid colon typically protrudes 1.5-2 cm from the abdomen, the ileostomy protrudes approximately 2-3 cm from the abdominal wall, and the urethrostomy protrudes 1.5-2 cm from the abdominal wall, this embodiment sets the length of the sealing column 1 to 10-15 cm, and the length of the second airbag 3 to 3-5 cm, facilitating contact between the second airbag 3 and different ostomies.

[0039] The connecting outer abutment block 42 has symmetrically arranged slide rails 422 on its left and right sides along its height direction on its inner peripheral wall. A slider 412 is fixedly installed on the bottom of the outer peripheral wall of the connecting inner tube 41 at a position corresponding to the left and right slide rails 422. The slider 412 is slidably disposed within the slide rails 422. Furthermore, to increase the sliding resistance between the slider 412 and the slide rails 422, in this embodiment, a limiting flange 4121 is fixedly installed at the outer end of each slider 412 on both sides. Several limiting grooves 4221 for cooperating with the limiting flanges 4121 are equidistantly spaced along the height direction within the slide rails 422 on both sides. A gap is left between the connecting outer abutment block 42 and the sealing column 1 for placing the second airbag 3.

[0040] Furthermore, the bottom surfaces of both the first adhesive layer and the second adhesive layer 421 are covered with dustproof paper.

[0041] Furthermore, the waterproof plastic film 6 is folded and placed inside the connecting housing 5.

[0042] The working principle is roughly as follows:

[0043] After the medical staff removes the old ostomy bag, they insert the bottom end of the sealing column 1 into the stoma, ensuring that the first air bladder 2 at the bottom of the sealing column 1 is completely inside the stoma. At this time, water or gas is injected into the first connecting tube 11 using a syringe, causing the first air bladder 2 to inflate after being filled with water or gas, pulling the sealing column 1 outward so that the first air bladder 2... Figure 2 As shown, it abuts against the inner wall of the stoma;

[0044] After determining the position of the first airbag 2, rotate the connecting block 4 downwards to the bottom of the external thread 15. At this time, push the connecting outer abutment block 42 downwards again so that the adhesive layer on the bottom surface of the connecting outer abutment block 42 abuts against the outer side of the patient's abdomen (the stoma is generally set in a relatively flat abdomen. Under normal circumstances, the lower end surface of most connecting outer abutment blocks 42 can touch the patient's abdomen. In a few cases, the lower end surface of the connecting outer abutment block 42 cannot completely touch the patient's abdomen. Try to make its lower end surface touch the patient's abdomen as much as possible to increase the stability of the connection between the connecting outer abutment block 42 and the patient's abdomen). Then, inject water and gas into the second connecting tube 142 through a syringe so that the second airbag 3 expands after being injected with water or inflated and abuts against the inner wall of the stoma to seal the stoma.

[0045] Finally, after the patient's stoma skin has been cleaned and the new stoma baseplate has been connected, the waterproof plastic film 6 is pasted onto the stoma baseplate through the first adhesive layer at its movable end port, as shown in the image. Figure 3 As shown, the sealing column 1, connecting block 4, waterproof plastic membrane 6, and stoma base plate enclose a relatively sealed space; by sequentially drawing air or water into the first airbag 2 or the second airbag 3 with a syringe, it contracts, at which point the sealing column 1 is pulled outward. As the sealing column 1 moves outward from the stoma, the waterproof plastic membrane 6, folded and placed inside the connecting shell 5, is stretched outward as... Figure 4 As shown, during the cleaning of the patient's skin, fecal matter and other fluids accumulated in the patient's body flow into the sealed space formed by the waterproof plastic membrane 6. After the fecal matter is discharged, the connection between the waterproof plastic membrane 6 and the stoma base plate is released (the waterproof plastic membrane 6 and the sealing column 1 are as follows). Figure 5 (As shown), close its movable end and then discard it.
