Description

Technical Field

[0001] This invention relates to the field of stoma cleaning technology, and more specifically to a stoma cleaning device. Background Technology

[0002] An ostomy is caused by diseases of the digestive or urinary system and requires surgical treatment to separate the intestinal tract and bring one end of the intestinal tract to the body surface (the anus or urethra is moved to the abdominal wall) to form an opening. An ostomy can achieve intestinal decompression, reduce obstruction, protect distal intestinal anastomoses or injuries, promote the healing of intestinal and urinary tract diseases, and even save the patient's life.

[0003] A stoma is typically used for rectal or bladder diseases (such as rectal cancer, bladder cancer, intestinal obstruction, etc.). To save the patient's life, doctors surgically remove the affected area; for example, in rectal cancer, the rectum and anal canal are removed, and in bladder cancer, the bladder is removed. An incision is then made on the left or right side of the patient's abdomen. Stool or urine is involuntarily expelled through this stoma. After discharge, these patients will need a bag attached to the stoma to collect the excrement.

[0004] For patients with ostomy, when changing the ostomy bag, the patient or their family needs to first remove the dirt, wash the stoma and surrounding skin with warm water until clean, and then dry the skin around the stoma with a paper towel. However, in clinical nursing, it has been found that patients and their families are afraid to touch the stoma, resulting in the stoma not being cleaned properly. This can lead to skin damage to the stoma, fecal dermatitis, and other problems, causing great suffering to the patient. Summary of the Invention

[0005] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by the present invention is that patients and their families are afraid to touch the stoma, resulting in the stoma not being cleaned properly.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a stoma cleaning device, comprising:

[0007] A cover, with one end of the cover open;

[0008] A cleaning mechanism, mounted on the cover, capable of spraying water toward the opening of the cover; and

[0009] Waste liquid recycling mechanism, which can recycle wastewater after cleaning inside the hood.

[0010] In this invention, the stoma is placed inside the mask by contacting the patient's skin through the opening of the mask. Then, the cleaning mechanism is controlled to spray water toward the stoma to clean the stoma and the skin around it. The waste liquid after cleaning is covered by the mask, and then the waste liquid recycling mechanism is controlled to collect the waste water after cleaning inside the mask. In this way, the stoma can be cleaned manually, reducing the psychological burden on patients and their families.

[0011] Preferably, the cleaning mechanism includes: a base, a spray head, a water inlet pipe, a water extraction pipe, and a first pump body; the base is mounted on the cover, and a water storage chamber is provided on the base; the spray head is mounted on the side of the base near the opening of the cover; one end of the water inlet pipe is connected to the spray head, the other end of the water inlet pipe is connected to one end of the water extraction pipe, and the other end of the water extraction pipe is connected to the water storage chamber; the first pump body is mounted on the water extraction pipe.

[0012] The first pump body draws water from the storage chamber into the inlet pipe through the pumping pipe. The inlet pipe then delivers the water into the spray head, which sprays the water onto the stoma to clean the stoma and the surrounding skin.

[0013] Preferably, the cover includes: a sliding ring, a rubber ring, an abutment ring, a mounting bracket, and a spreading spring; the sliding ring, rubber ring, and abutment ring are sequentially sleeved on the base; the end of the sliding ring away from the abutment ring is slidably engaged with the base; the abutment ring is fixedly mounted on the base by the mounting bracket; the two ends of the rubber ring are respectively fixedly connected to the sliding ring and the abutment ring; one end of the spreading spring abuts against the mounting bracket, and the other end of the spreading spring abuts against the sliding ring.

[0014] Press the sliding ring towards the abutment ring, causing the abutment ring to compress and expand the spring, and squeeze and deform the rubber ring, reducing the space of the mask; then, the end of the abutment ring away from the rubber ring abuts against the annular skin, and then release the sliding ring, expand the spring and push the sliding ring to slide away from the abutment ring. In this way, a negative pressure is formed inside the mask, so that the mask adheres to the patient's skin, thereby effectively preventing waste liquid from seeping out from the abutment ring.

[0015] Preferably, it also includes a self-locking mechanism, which can control the opening and closing of the water inlet pipe according to the magnitude of the negative pressure inside the cover.

[0016] When the internal pressure of the cover is less than the external pressure, it indicates that there is no gap between the abutment ring and the skin, and wastewater will not leak out. Therefore, the self-locking mechanism controls the water inlet pipe to remain open. When the internal pressure of the cover is the same as the external pressure, it indicates that there is a gap between the abutment ring and the skin, and wastewater may leak out. Therefore, the self-locking mechanism controls the water inlet pipe to be disconnected to prevent a large amount of wastewater from leaking out from the gap.

[0017] Preferably, the self-locking mechanism includes: a sliding tube, a pusher column, a sealing plate, a return spring, and a detection and pushing assembly; the water inlet pipe is connected to the spray head through the sliding tube; the sealing plate is located inside the water inlet pipe to seal it; the sealing plate is L-shaped, with its long end hinged to the water inlet pipe and its short end located away from the spray head, abutting against the inner wall of the water inlet pipe; one end of the sliding tube is slidably inserted into the inside of the water inlet pipe, and the other end is slidably inserted into the inside of the spray head; the pusher column is installed at the end of the sliding tube near the sealing plate; the return spring applies a spring force to the water inlet pipe toward the sealing plate; the detection and pushing assembly can detect the negative pressure inside the enclosure to push the sliding tube toward the sealing plate.

[0018] When the detection and pushing component detects negative pressure inside the cover, it pushes the sliding tube toward the sealing plate. The sliding tube drives the push column to rotate the sealing plate, while simultaneously compressing the return spring, creating a gap between the sealing plate and the water inlet pipe. This allows water to enter the spray head through the sliding tube. When the detection and pushing component detects that the pressure inside the cover is the same as the external pressure, and the water in the water inlet pipe flows toward the sliding tube, it pushes the sealing plate to rotate in the opposite direction. At the same time, the return spring pushes the water inlet pipe to return to its original position, causing the short end of the sealing plate to abut against the inner wall of the water inlet pipe. This seals and isolates the water inlet pipe, preventing a large amount of water from flowing into the cover and seeping out.

[0019] Preferably, the detection and pushing assembly includes: a fixed block and a return spring; the fixed block is fixedly mounted on the sliding tube; an air cavity is formed in the base, and the air cavity is connected to the outside through a pipe; the sliding block is slidably mounted on the base, with one end of the sliding block extending into the cover body and the other end of the sliding block extending into the air cavity; the fixed block and the sliding block are respectively provided with mutually parallel and slidably abutting inclined surfaces, and the sliding block moves toward the cover body to drive the fixed block toward the sealing plate through the inclined surfaces; the return spring applies a spring force to the sliding block to slide toward the air cavity.

[0020] When negative pressure is generated inside the enclosure, the air chamber is connected to the outside air through a pipe, and the pressure inside the air chamber is atmospheric pressure. Therefore, the pressure inside the enclosure is less than the pressure inside the air chamber, which pushes the sliding block to slide into the enclosure. At the same time, the sliding block compresses the return spring, and the sliding block drives the fixed block to move towards the sealing plate through the inclined plane. In turn, the fixed block drives the sliding tube to move towards the sealing plate. When the pressure inside the enclosure is the same as the pressure inside the air chamber, the return spring drives the sliding block to reset.

[0021] Preferably, the wastewater recycling mechanism includes: a recycling pipe and a second pump body; a recycling chamber is provided on the base, one end of the recycling pipe is connected to the recycling chamber, and the other end of the recycling pipe extends into the housing; the second pump body is installed on the recycling pipe. When the second pump body operates, it transports the cleaned wastewater into the recycling chamber through the recycling pipe.

[0022] Preferably, a rubber ring is installed at the end of the abutment ring away from the rubber ring, and a groove is formed on the side of the rubber ring away from the rubber ring. The elastic deformation of the rubber ring allows it to fit more easily against the skin, and the elastic deformation of the rubber ring also allows the groove to adhere to the skin, increasing the connection strength between the rubber ring and the skin.

[0023] Preferably, the spray head includes a connecting pipe and a spray pipe; the connecting pipe is mounted on the base, the sliding pipe is inserted into one end of the connecting pipe, the other end of the connecting pipe is connected to the spray pipe, and the spray pipe has multiple spray holes on the side away from the connecting pipe.

[0024] The sliding tube delivers water into the connecting tube, and the water enters the spray pipe through the connecting tube. Then, it is sprayed through the spray hole onto the stoma and the skin near the stoma to clean the stoma area.

[0025] Preferably, it further includes a drive mechanism, which includes: a motor, an external gear ring, a gear, and a cleaning cotton; the connecting pipe is rotatably mounted on the base, the water spray pipe is perpendicular to the connecting pipe, and the cleaning cotton is installed on the side of the water spray pipe with water spray holes; the external gear ring is coaxially fixed with the connecting pipe; the gear is rotatably mounted on the base and meshes with the external gear ring, and the motor can drive the gear to rotate.

[0026] The motor drives the gear to rotate, and the gear drives the connecting pipe to rotate through the gear ring. The connecting pipe drives the water spray pipe to rotate, and the water spray pipe drives the cleaning cotton to rotate. Through the cooperation of the water spraying holes, secondary cleaning of the skin near the stoma is achieved.

[0027] Compared with the prior art, the present invention has at least the following advantages:

[0028] 1. In this invention, the stoma is placed inside the mask by contacting the patient's skin through the opening of the mask. Then, the cleaning mechanism is controlled to spray water toward the stoma to clean the stoma and the skin around the stoma. The waste liquid after cleaning is covered by the mask. Then, the waste liquid recycling mechanism is controlled to collect the waste water after cleaning inside the mask. In this way, the stoma can be cleaned manually, reducing the psychological burden on patients and their families.

[0029] 2. In this invention, the sliding ring is pressed towards the abutment ring, causing the abutment ring to compress and expand the spring, and squeeze and deform the rubber ring, reducing the space of the cover; then the end of the abutment ring away from the rubber ring abuts against the annular skin, and then the sliding ring is released, the spring is expanded and the sliding ring is pushed to slide towards the side away from the abutment ring. In this way, a negative pressure is formed in the cover, so that the cover is adsorbed on the patient's skin, thereby effectively preventing waste liquid from seeping out from the abutment point of the abutment ring.

[0030] 3. In this invention, when the internal pressure of the cover is less than the external pressure, it indicates that there is no gap between the abutment ring and the skin, and wastewater will not leak out. Therefore, the self-locking mechanism controls the water inlet pipe to be connected. When the internal pressure of the cover is the same as the external pressure, it indicates that there is a gap between the abutment ring and the skin, and wastewater may leak out. Therefore, the self-locking mechanism controls the water inlet pipe to be disconnected to prevent a large amount of wastewater from leaking out from the gap.

[0031] 4. In this invention, when negative pressure is generated inside the cover, since the air chamber is connected to the outside air through the pipe, the pressure inside the air chamber is atmospheric pressure. Therefore, the pressure inside the cover is less than the pressure inside the air chamber, which pushes the sliding block to slide towards the cover. At the same time, the sliding block compresses the return spring, and the sliding block drives the fixed block to move towards the sealing plate through the inclined surface, which in turn drives the sliding tube to move towards the sealing plate through the fixed block. When the pressure inside the cover is the same as the pressure inside the air chamber, the return spring drives the sliding block to reset.

[0032] 5. In this invention, the elastic deformation of the rubber ring makes it easier to fit snugly against the skin, and the elastic deformation of the rubber ring allows the groove to adhere to the skin, thereby increasing the connection strength between the rubber ring and the skin.

[0033] 6. In this invention, the motor drives the gear to rotate, the gear drives the connecting pipe to rotate through the gear ring, the connecting pipe drives the water spray pipe to rotate, and the water spray pipe drives the cleaning cotton to rotate. Through the cooperation of water spraying and cleaning with the water spray hole, secondary cleaning of the skin near the stoma is achieved. Attached Figure Description

[0044] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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 invention according to the specific circumstances.

[0045] See Figures 1-6 The present invention provides an embodiment of a stoma cleaning device, comprising: a cover 1, a cleaning mechanism 2, and a waste liquid recovery mechanism; one end of the cover 1 is open; the cleaning mechanism 2 is installed on the cover 1 and can spray water toward the opening of the cover 1; the waste liquid recovery mechanism can recover the wastewater after cleaning inside the cover 1.

[0046] In practice, the stoma is placed inside the mask 1 by contacting the patient's skin through the opening of the mask 1. Then, the cleaning mechanism 2 is controlled to spray water toward the stoma to clean the stoma and the skin around it. The waste liquid after cleaning is covered by the mask 1. Then, the waste liquid recycling mechanism is controlled to collect the waste water inside the mask 1. In this way, the stoma can be cleaned manually, reducing the psychological burden on the patient and their family.

[0047] See Figures 1-6 In other embodiments, the cleaning mechanism 2 includes: a base 21, a spray head 22, a water inlet pipe 23, a water extraction pipe 24, and a first pump body; the base 21 is mounted on the cover 1, and a water storage chamber 211 is provided on the base 21; the spray head 22 is mounted on the side of the base 21 near the opening of the cover 1; one end of the water inlet pipe 23 is connected to the spray head 22, and the other end of the water inlet pipe 23 is connected to one end of the water extraction pipe 24, and the other end of the water extraction pipe 24 is connected to the water storage chamber 211; the first pump body is mounted on the water extraction pipe 24. In specific implementation, when the first pump body is activated, the first pump body draws water from the water storage chamber 211 into the water inlet pipe 23 through the water extraction pipe 24, the water inlet pipe 23 delivers water into the spray head, and the spray head 22 sprays water onto the stoma, thereby cleaning the stoma and the skin near the stoma.

[0048] See Figures 1-2 In other embodiments, the cover 1 includes: a sliding ring 11, a rubber ring 12, an abutment ring 13, a mounting bracket 14, and a spreading spring 15; the sliding ring 11, the rubber ring 12, and the abutment ring 13 are sequentially sleeved on the base 21; one end of the sliding ring away from the abutment ring 13 is slidably engaged with the base 21; the abutment ring 13 is fixedly mounted on the base 21 by the mounting bracket 14; the two ends of the rubber ring 12 are respectively fixedly connected to the sliding ring 11 and the abutment ring 13; one end of the spreading spring 15 abuts against the mounting bracket 14, and the other end of the spreading spring 15 abuts against the sliding ring 11.

[0049] In practice, the sliding ring 11 is pressed towards the abutment ring 13, causing the abutment ring 13 to compress and expand the spring 15, and to squeeze and deform the rubber ring 12, reducing the space of the cover 1. Then, the end of the abutment ring 13 away from the rubber ring 12 is brought into contact with the annular skin. The sliding ring 11 is then released, and the spring 15 is expanded to push the sliding ring 11 to slide away from the abutment ring 13. In this way, a negative pressure is formed inside the cover 1, so that the cover 1 is attached to the patient's skin, thereby effectively preventing waste liquid from seeping out from the abutment point of the abutment ring 13.

[0050] See Figures 1-5 In other embodiments, a self-locking mechanism 3 is also included. The self-locking mechanism 3 can control the opening and closing of the water inlet pipe 23 according to the magnitude of the negative pressure inside the cover 1. Specifically, when the internal pressure of the cover 1 is less than the external pressure, it indicates that there is no gap between the abutment ring 13 and the skin, and wastewater will not seep out. Therefore, the self-locking mechanism 3 controls the water inlet pipe 23 to be open. When the internal pressure of the cover 1 is the same as the external pressure, it indicates that there is a gap between the abutment ring 13 and the skin, and wastewater may seep out. Therefore, the self-locking mechanism 3 controls the water inlet pipe 23 to be closed to prevent a large amount of wastewater from seeping out from the gap.

[0051] See Figures 1-5 In other embodiments, the self-locking mechanism 3 includes: a sliding tube 31, a pusher 32, a sealing plate 33, a return spring 34, and a detection and pushing assembly; the water inlet pipe 23 is connected to the spray head 22 through the sliding tube 31; the sealing plate 33 is located inside the water inlet pipe 23 to seal the water inlet pipe 23; the sealing plate 33 is L-shaped, and the long end of the sealing plate 33 is hinged to the water inlet pipe 23, the short end of the sealing plate 33 is located on the side away from the spray head 22, and the short end of the sealing plate 33 abuts against the inner wall of the water inlet pipe 23; one end of the sliding tube 31 is slidably inserted into the inside of the water inlet pipe 23, and the other end of the sliding tube 31 is slidably inserted into the inside of the spray head 22; the pusher 32 is installed at the end of the sliding tube 31 near the sealing plate 33; the return spring 34 applies a spring force toward the sealing plate 33 to the water inlet pipe 23; the detection and pushing assembly can detect the negative pressure inside the cover 1 to push the sliding tube 31 toward the sealing plate 33.

[0052] In specific implementation, when the detection and pushing component detects negative pressure inside the cover 1, it pushes the sliding tube 31 toward the sealing plate 33. The sliding tube 31 drives the push column 32 to rotate the sealing plate 33, while simultaneously compressing the return spring 34, creating a gap between the sealing plate 33 and the water inlet pipe 23, allowing water to enter the spray head 22 through the sliding tube 31. When the detection and pushing component detects that the pressure inside the cover 1 is the same as the external pressure, and the water in the water inlet pipe 23 flows toward the sliding tube 31, it pushes the sealing plate 33 to rotate in the opposite direction. At the same time, the return spring 34 pushes the water inlet pipe 23 to return to its original position, causing the short end of the sealing plate 33 to abut against the inner wall of the water inlet pipe 23, thereby sealing and isolating the water inlet pipe 23 to prevent a large amount of water from flowing into the cover 1 through the water inlet pipe 23 and seeping out.

[0053] See Figures 1-5 In other embodiments, the detection and pushing assembly includes: a fixed block 35 and a return spring 37; the fixed block 35 is fixedly mounted on the sliding tube 31; an air cavity 212 is provided in the base 21, and the air cavity 212 is connected to the outside through a pipe; the sliding block 36 is slidably mounted on the base 21, and one end of the sliding block 36 extends into the cover 1, and the other end of the sliding block 36 extends into the air cavity 212; the fixed block 35 and the sliding block 36 are respectively provided with inclined surfaces 38 that are parallel to each other and slide against each other, and the sliding block 36 moves toward the cover 1 so as to drive the fixed block 35 toward the sealing plate 33 through the inclined surface 38; the return spring 37 applies a spring force to the sliding block 36 to slide toward the air cavity 212.

[0054] In practice, when negative pressure is generated inside the cover 1, since the air chamber 212 is connected to the outside air through the pipe, the pressure inside the air chamber 212 is atmospheric pressure. Therefore, the pressure inside the cover 1 is less than the pressure inside the air chamber 212, which pushes the sliding block 36 to slide towards the inside of the cover 1. At the same time, the sliding block 36 compresses the return spring 37. The sliding block 36 drives the fixed block 35 to move towards the sealing plate 33 through the inclined surface 38. In turn, the fixed block 35 drives the sliding tube 31 to move towards the sealing plate 33. When the pressure inside the cover 1 is the same as the pressure inside the air chamber 212, the return spring 37 drives the sliding block 36 to reset.

[0055] See Figures 1-3 In other embodiments, the wastewater recycling mechanism includes: a recycling pipe and a second pump body; a recycling chamber 213 is provided on the base 21, one end of the recycling pipe is connected to the recycling chamber 213, and the other end of the recycling pipe extends into the cover 1; the second pump body is installed on the recycling pipe. In specific implementation, the second pump body operates, and the second pump body transports the cleaned waste liquid to the recycling chamber 213 through the recycling pipe.

[0056] See Figures 1-2In other embodiments, a rubber ring 4 is installed at the end of the abutment ring 13 away from the rubber ring 12, and a groove 41 is formed on the side of the rubber ring 4 away from the rubber ring 12. In specific implementation, the elastic deformation of the rubber ring 4 makes it easier to fit tightly to the skin, and the elastic deformation of the rubber ring 4 allows the groove 41 to adhere to the skin, thereby improving the connection strength between the rubber ring 4 and the skin.

[0057] See Figures 1-6 In other embodiments, the spray head 22 includes a connecting pipe 221 and a spray pipe 222. The connecting pipe 221 is mounted on the base 21, and a sliding pipe 31 is inserted into one end of the connecting pipe 221. The other end of the connecting pipe 221 is connected to the spray pipe 222. The spray pipe 222 has multiple spray holes 223 on the side away from the connecting pipe 221. In specific implementation, the sliding pipe 31 delivers water into the connecting pipe 221. The water enters the spray pipe 222 through the connecting pipe 221 and is then sprayed through the spray holes 223 onto the stoma and the skin near the stoma to clean the stoma area.

[0058] See Figures 1-3 In another embodiment, a drive mechanism 5 is also included. The drive mechanism 5 includes a motor 51, an external gear ring 52, a gear 53, and a cleaning cotton 54. The connecting pipe 221 is rotatably mounted on the base 21, the water spray pipe 222 is arranged perpendicularly to the connecting pipe 221, and the cleaning cotton 54 is installed on the side of the water spray pipe 222 where the water spray hole 223 is opened. The external gear ring 52 is coaxially fixed with the connecting pipe 221. The gear 53 is rotatably mounted on the base 21 and meshes with the external gear ring 52. The motor 51 can drive the gear 53 to rotate.

[0059] In practice, the motor 51 is activated, driving the gear 53 to rotate. The gear 53 drives the connecting pipe 221 to rotate through the gear ring. The connecting pipe 221 drives the water spray pipe 222 to rotate. The water spray pipe 222 drives the cleaning cotton 54 to rotate. Through the cooperation of water spraying and cleaning with the water spray hole 223, secondary cleaning of the skin near the stoma is achieved.
