Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, in particular to a leakage-proof ostomy bag. Background Art

[0002] An ostomy bag is a medical device used to store human waste, such as urine and feces. It is also called a colostomy bag and is a medical device used to collect and store waste that passes through the human intestine. It is commonly seen in patients who have undergone a colostomy. A colostomy is a surgical procedure that connects a section of the intestine to the abdominal wall to form an artificial opening. The bag collects waste, allowing patients to continuously excrete waste.

[0003] Before using existing medical ostomy bags, medical staff usually need to use calipers to measure the size of the patient's excretory opening, and then use scissors to cut a round hole on the bottom plate of the ostomy bag to fit the size of the excretory opening. The bag is then glued to the excretory opening. Manually cutting the round hole on the bottom plate will result in inaccurate and irregular cutting. The cut may be too large or too small. If it is too large, it will not match the size of the stoma, resulting in the ostomy bag not fitting and sealing properly, affecting the adhesion and sealing of the ostomy bag, causing the undamaged skin around the patient's excretory opening to directly contact excrement, which is likely to increase the risk of leakage and infection. If the cut is too small, the bottom plate of the bag will directly contact the skin of the excretory opening, which is likely to cause scratches, irritation or tears to the excretory opening, causing pain, discomfort and inflammation.

[0004] Secondly, when patients use an ostomy bag, they usually need to wear it for a week before replacing it. Therefore, after excrement enters the ostomy bag, it may adhere to the inner wall of the bag around the excretion opening. Since the ostomy bag is usually used in a sealed manner and is not cleaned for a long time, when the patient lies down, the excrement adhered to the inner wall of the ostomy bag will be close to the excretion opening of the patient's skin due to inertia, causing the patient's excretion opening to be contaminated by excrement for a long time, which can easily cause bacterial infection in the patient's excretion opening.

[0005] In view of this, the present invention provides a leakage-proof ostomy bag. Summary of the Invention

[0019] (3) Beneficial effects

[0020] The leak-proof ostomy bag provided by the present invention has the following beneficial effects:

[0021] By pressing the pressing rod and then twisting it clockwise, the curved blade drives the elastic cover to rotate frictionally in the circular elastic splint. After rotating about forty-five degrees, that is, when the other sliding sleeve column corresponds to the position of the piston cylinder, the rotation can be stopped, and the curved blade can be rotated one circle to cut the opening on the pocket bottom plate, thereby completing the size cutting of the pocket body, ensuring that the edge of the pocket bottom plate after cutting is regular, avoiding inaccurate cutting and mismatching with the stoma size, ensuring that the stoma bag can be correctly fitted and sealed, and reducing the phenomenon that the skin around the stoma loses protection due to long-term contact with excrement caused by the excessive size of the pocket bottom plate, and the skin is damaged. In addition, the size can be adjusted according to the size of the excreta of different patients, and the purpose of regular cutting can be achieved.

[0022] After the pocket body is cut, one side of the pocket bottom plate can be aligned with the stoma on the patient's skin surface for fitting. After the pocket body is pasted to the human skin surface, the two sides of the elastic cover can be pinched again to make it elastically deformed and detached from the circular elastic splint, and the elastic cover can be smoothly removed as a whole, and then the original stoma bag cover plate can be installed on the pocket body. The disassembled elastic cover can be disinfected and stored, and the new stoma bag bottom plate can be cut when the pocket body needs to be replaced next time, so as to achieve the purpose of multiple recycling and will not be discarded with the pocket body. Therefore, each batch of stoma bags used for a short time only needs to be equipped with one elastic cover to complete the cutting of a large number of stoma bag bottom plates, thereby achieving the purpose of resource utilization;

[0023] The arc-shaped suction cup absorbs the skin around the patient's excretion opening to achieve the purpose of auxiliary fixation. Compared with the traditional method of using only film bonding, this adsorption and bonding effect can effectively enhance the adhesion of the pocket body to the human skin, and further reduce the risk of the pocket body falling off due to loose adhesion.

[0024] When the rotating sleeve and the cleaning rod rotate, the cleaning range of the inner wall of the pocket body can be extended, and when the second pull rope moves, it will also drive the long rod to slide on the upper part of the baffle plate, thereby cleaning the baffle plate, thereby preventing waste liquid residue from condensing on the upper part of the pocket body and breeding bacteria to contaminate the patient's excretion port when the wearer is continuously worn, thereby keeping the inner wall of the pocket near the excretion port clean;

[0025] When the patient lies on his side, the liquid under the baffle plate will shake and move toward the baffle plate. At this time, the two blocking blocks can prevent the liquid inlet plate from rotating toward the second pull rope, thereby preventing the waste liquid entering the pocket body from flowing back to the upper part of the pocket body through the liquid inlet plate again, preventing the patient's skin from being soaked and contaminated by the waste liquid when the patient lies on his side, and ensuring the dryness of the patient's excretion port.

[0049] The V-shaped lower end of the second pull rope 65 is fixedly connected to the long rod 69 , and the inner wall of the pocket body 1 is symmetrically fixedly connected with an auxiliary spring 611 , and the lower end of the auxiliary spring 611 is fixedly connected to the outer wall of the rotating sleeve 66 .

[0050] The following is the entire working process and working principle of the above embodiment:

[0051] Initial use: The original stoma surface of the pocket body 1 has a disc surface with size markings, namely the pocket bottom plate 7, and the other side is provided with a detachable cover. Since the elastic cover 3 and the circular elastic splint 48 are made of elastic material, the detachable cover originally connected to the opening of the pocket body 1 needs to be removed when in use. Then, by manually pinching the two sides of the elastic cover 3, the end of the elastic cover 3 close to the circular elastic splint 48 is elastically deformed, so that the size of the bottom end 3 of the elastic cover is reduced, and the elastic cover 3 can be smoothly inserted into the pocket body. The interior of the pocket body 1 is inserted into the pocket body 1 and aligned with the circular elastic clamping plate 48, so that the elastic cover 3 can be loosened. At this time, the elastic cover 3 is elastically reset and can be snapped into the circular elastic clamping plate 48, so as to achieve the purpose of detachable installation. After the elastic cover 3 is inserted, the arc-shaped blade 46 installed inside it does not fit the inner wall of the pocket body 1, and the openings on the front and back sides of the pocket body 1 are both set to be inwardly protruded. Therefore, the cleaning rod 67 is horizontal at this time and is abutted by the raised edge inside the pocket body 1, so that the reset spring 68 inside the rotating sleeve 66 is in a compressed state;

[0052] Specifically, first, the staff measures the size of the pocket bottom plate 7 of the pocket body 1 required by the patient according to the needs, and then one side of the pocket bottom plate 7 can be fitted to the upper part of the desktop, and then the rotating rod 410 is manually pulled upward to disengage it from the originally engaged adjustment limit plate 411. At this time, the rotating disk 41 can be driven to rotate clockwise by pushing the rotating rod 410. When the rotating disk 41 rotates, the arc groove 42 opened on its surface will squeeze the sliding column 45 on the inner wall. Since the sliding column 44 is limited and slidably connected to the limit groove 43 in the elastic cover 3, the squeezed multiple sliding columns 44 can only drive the sliding rod 45 and the arc blade 46 to slide closer to the middle. After the arc blade 46 moves to the size of the pocket bottom plate 7 to be cut, the rotating rod 410 can be pressed downward to make it engage in the corresponding adjustment limit plate 411, so that the adjusted size can be fixed to avoid sliding displacement during cutting, and then the pressing rod 49 on its upper part is manually pressed to press the sliding rod 45 The sliding post 44 slides in the sliding sleeve and drives the limit spring 47 to stretch, which can drive the sliding rod 45 to move in the direction away from the elastic cover 3, so that the curved blade 46 presses and cuts the adjusted pocket bottom plate 7 position. After pressing the pressing rod 49, it can be manually twisted clockwise so that the curved blade 46 drives the elastic cover 3 to rotate frictionally in the circular elastic clamping plate 48. After rotating about forty-five degrees, that is, after the other sliding sleeve post 44 corresponds to the position of the piston cylinder 2, the rotation can be stopped, and the curved blade 46 can be allowed to rotate one circle to cut the opening on the pocket bottom plate 7, thereby completing the size cutting of the pocket body 1, ensuring that the edge of the pocket bottom plate 7 after cutting is regular, avoiding inaccurate shearing and mismatching with the stoma size, ensuring that the stoma bag can be correctly fitted and sealed, reducing the phenomenon that the pocket bottom plate 7 is too large and causes the skin around the stoma to lose protection and long-term contact with excrement, thereby damaging the skin. In addition, the size can be adjusted according to the size of the excreta of different patients, and the purpose of regular cutting can also be achieved.

[0053] Furthermore, after the elastic cover 3 is inserted into the pocket body 1 as a whole, a magnetic plate 412 is provided on the outer wall of the sliding rod 45 at the corresponding position thereof, and the magnetic plate 412 and the magnetic disk 54 have the same magnetic poles, and the two repel each other. Therefore, after the magnetic plate 412 enters the pocket body 1, the corresponding magnetic plate 412 will generate a repulsive force on the magnetic disk 54, causing the magnetic disk 54 to push the piston push rod 51 fixedly connected to it to slide inside the piston cylinder 2 and approach the one-way air outlet valve tube 52, and also press the support spring 53 on its surface to stretch, so that the air inside the piston cylinder 2 is discharged from the one-way air outlet valve tube 52. After the pocket body 1 is cut, one side of the pocket bottom plate 7 can be aligned with the patient's skin. The elastic cover 3 can be removed as a whole smoothly, and the original ostomy bag cover plate and the pocket body 1 can be installed again. The disassembled elastic cover 3 can be disinfected and stored. When the pocket body 1 needs to be replaced next time, the new ostomy bag can be cut into the chassis, thereby achieving the purpose of multiple recycling and will not be discarded together with the pocket body 1. Therefore, each batch of ostomy bags used for a short time only needs to be equipped with one elastic cover 3 to complete the cutting of a large number of ostomy bag chassis 7, thereby achieving the purpose of resource utilization;

[0054] It should be noted that after the magnetic plate 412 follows the elastic cover 3 to separate from the pocket body 1, the magnetic plate 412 no longer generates a repulsive force relative to the magnetic disk 54. At this time, the originally compressed support spring 53 will be reset, thereby pulling the piston push rod 51 to slide toward the magnetic disk 54. At this time, the suction force generated by the movement of the piston push rod 51 inside the piston cylinder 2 can be sucked in through the one-way air intake valve tube 55 and the arc-shaped suction cup 56. At this time, the arc-shaped suction cup 56 has been attached to the patient's skin surface through the above steps, so it will generate suction on the patient's skin, allowing the arc-shaped suction cup 56 to adsorb the patient's skin, thereby achieving the effect of auxiliary fixation. Compared with the traditional effect of only using film bonding, this adsorption and bonding effect can effectively enhance the adhesion of the pocket body 1 to human skin, and further reduce the risk of the pocket body 1 falling off due to loose adhesion.

[0055] Furthermore, when the patient discharges waste liquid, it will flow into the interior of the bag body 1 through the stoma opened in the bag bottom plate 7. The gravity of the waste liquid will fall on the upper part of the baffle plate 61 and press the liquid inlet plate 62 to rotate downward, and fall into the lower part of the baffle plate 61 through the opening of the liquid inlet plate 62. The rotation of the liquid inlet plate 62 will pull the first pull rope 64 and the second pull rope 65 downward through the sleeve frame 63. Since the first pull rope 64 and the second pull rope 65 are initially in a taut state, they will synchronously pull the rotating sleeve 66 fixedly connected to the upper end of the second pull rope 65 and the cleaning rod 67 inside it to rotate downward synchronously, and pull the outer wall of the rotating sleeve 66 The return spring 68 is stretched. At this time, the cleaning rod 67 that was originally in contact with the inner edge of the pocket body 1 will lose its resistance, causing the return spring 68 to return to its original position and rebound, thereby pushing the cleaning rod 67 to slide out of the rotating sleeve 66. As a result, when the rotating sleeve 66 and the cleaning rod 67 rotate, the cleaning range of the inner wall of the pocket body 1 can be extended. When the second pull rope 65 moves, it will also drive the long rod 69 to slide on the upper part of the baffle 61, thereby also cleaning the baffle 61, thereby preventing waste liquid residue from condensing on the upper part of the pocket body 1 and breeding bacteria to contaminate the patient's excretion port when the patient is continuously worn, thereby keeping the inner wall of the pocket near the excretion port clean.

[0056] Secondly, when there is no excretion at the patient's stoma, the rebound force of the reset spring 68 will pull the rotating sleeve 66 and the second pull rope 65 and the first pull rope 64 to reset, thereby driving the long rod 69 and the liquid inlet plate 62 to rotate and reset. When the patient lies on his side, the liquid under the baffle 61 will shake and move toward the baffle 61. At this time, the two blocking blocks 610 can prevent the liquid inlet plate 62 from rotating toward the direction of the second pull rope 65, thereby preventing the waste liquid entering the pocket body 1 from flowing back to the upper part of the pocket body 1 through the liquid inlet plate 62 again, preventing the patient's skin from being soaked and contaminated by the waste liquid when the patient lies on his side, and ensuring the dryness of the patient's excretion port.
