[0002] Colorectal cancer is a common malignant tumor in the gastrointestinal tract. When a radical enterostomy operation is performed on a colorectal cancer patient, a stoma is formed by leading one end of the intestine out of the patient's abdomen, and the patient excretes through the stoma. A special stoma bag is installed on the patient's abdomen outside the stoma by adhesion and fixation to collect excrement.

[0003] In the prior art, the following defects exist when the stoma bag is pasted on the stoma position of the patient's abdomen:

[0004] 1. Physiological saline cleaning, stoma powder application and skin protection film spraying need to be performed in sequence. In the stoma powder application link, the medical staff usually sprays the powder around the stoma and then evenly applies it with a cotton swab. This process not only takes time and effort, but also has the risk of uneven application. If the operation force is not appropriate or the attention is distracted, it is easy to cause mechanical damage to the stoma.

[0005] 2. When the secondarily used stoma bag is pasted, it is often not fixed firmly due to the decrease in adhesion. During the patient's daily activities, the stoma bag base and the collection bag are easily pulled off due to the skin traction, muscle contraction or limb collision of the abdomen, affecting normal use.

A plurality of circular holes 4 are uniformly formed in the bottom of the storage cylinder 1 in the circumferential direction, and a circular disc 5 is slidingly installed in each circular hole 4. The outer diameter of the circular disc 5 matches the inner diameter of the circular hole 4, so that the circular disc 5 can slide up and down in the circular hole 4 without falling off.

[0053] In use, the storage cylinder 1 is placed on the top of the external rotating ring 20, and the positioning grooves 3 at the bottom of the positioning disc 2 are inserted with the pin shafts 19 on the rotating ring 20 to position the storage cylinder 1 and the positioning disc 2. At this time, the outer wall of the rubber wheel 7 is in contact with the top of the rotating ring 20.

[0054] Reference Figure 3 and Figure 4 A plurality of discharge ports 12 are uniformly formed in the circumferential direction inside each circular disc 5, and the discharge ports 12 are circular holes (or long strip-shaped through holes, which are not limited here) for guiding the stoma powder in the storage cylinder 1 out. Limiting rings 11 are arranged above and below the circular disc 5, respectively, and the two limiting rings 11 are fixed on the inner wall of the circular hole 4 to limit the up-down movement range of the circular disc 5 and prevent the circular disc 5 from falling out of the circular hole 4.

[0055] Reference Figures 2-4The device further comprises a vibrating structure for driving the disc 5 to move up and down.

The end of each rotating shaft 6 away from the rotating disc 8 extends into the positioning disc 2 and is fixedly connected with a rubber wheel 7, the outer wall of the rubber wheel 7 protrudes from the bottom of the positioning disc 2.

[0056] In operation, the storage cylinder 1 is manually driven to rotate, and the storage cylinder 1 drives the rotating shaft 6 and the rubber wheel 7 to revolve. Due to the friction between the rubber wheel 7 and the rotating ring 20, the rubber wheel 7 drives the rotating shaft 6 and the rotating disc 8 to rotate. The rotating disc 8 drives the disc 5 to move up and down through the fit with the rectangular slot 10, so that the ostomy powder in the storage cylinder 1 can be uniformly poured out through the discharge port 12. At the same time, the rotation of the storage cylinder 1 drives the disc 5 to rotate, ensuring that the ostomy powder can be uniformly sprayed on the perianal area.

[0057] With reference to Figure 5 and Figure 6 , the nursing device relates to the technical field of anorectal surgical nursing and comprises a fixed disc 13 which is in the shape of a disc and is rotatably connected with an annular rotating ring 20 at the top thereof through a rotating bearing. The fixed disc 13 is fixedly provided with a waistband 14 at each side thereof, and the ends of the two waistbands 14 away from each other are respectively sewn with a magic tape 15, the two magic tapes 15 are respectively a hook surface and a loop surface, and in use, the fixed disc 13 is sleeved on the abdomen of a patient and is fixedly connected through the magic tapes 15.

[0058] With reference to Figure 2 and Figure 6 , the fixed disc 13 is provided with the above-mentioned nursing device, which comprises the storage cylinder 1, the positioning disc 2, the disc 5, the vibrating structure and the like. The positioning disc 2 is placed on the top of the rotating ring 20, a plurality of pin shafts 19 are slidably arranged in the rotating ring 20, the bottom of the positioning disc 2 is provided with a plurality of positioning grooves 3, and the pin shafts 19 are in fit with the positioning grooves 3 and are used for positioning the positioning disc 2. The rubber wheel 7 on the outer wall of the storage cylinder 1 is in contact with the top of the rotating ring 20, the self-rotation of the rubber wheel 7 is realized through friction, the disc 5 is driven to move up and down, and the uniform spraying of the ostomy powder is realized.

[0059] With reference to Figure 6 and Figure 8The fixing structure further includes an adsorption structure for adsorbing and fixing the collecting bag on the ostomy bag. The adsorption structure includes an annular cavity 24 arranged in the fixing disc 13, and a plurality of communication pipes 25 fixed to the top of the fixing disc 13, the bottom end of each communication pipe 25 extending into the annular cavity 24, and a suction disc 26 fixed in communication with the top end of each communication pipe 25. A fixing cylinder 27 is further fixed in the fixing disc 13, and the annular cavity 24 and the fixing cylinder 27 are in communication through a hose 28. A piston plate 29 is sealingly and slidably connected in the fixing cylinder 27, the top of the piston plate 29 being rotatably connected with a threaded rod 30, and the top end of the threaded rod 30 being threadedly penetrated through the fixing cylinder 27 and extending above the fixing cylinder 27.

[0060] Specifically, when the bottom disc 37 needs to be fixed, the rotating ring 20 is rotated to drive the arc-shaped grooves 21 to rotate, the pin shaft 19 is simultaneously in sliding cooperation with the arc-shaped grooves 21 and the track grooves 18 to drive the pressing blocks 17 to move towards the middle, the bottom of each pressing block 17 is fixed with a rubber pad for increasing the pressing effect on the bottom disc 37 and preventing the bottom disc 37 from easily falling off, and the bottom contact surface of the rubber pad can be designed as an arc shape, a sawtooth shape or a honeycomb texture, and the sawtooth anti-skid pattern (with a tooth height of 0.5-1 mm and a tooth pitch of 2-3 mm) can increase the friction coefficient between the rubber pad and the bottom disc 37 to 0.4-0.6.

[0061] With reference to Figure 6 and Figure 7 , the fixing structure further includes an adsorption structure for adsorbing and fixing the collecting bag on the ostomy bag. The adsorption structure includes an annular cavity 24 arranged in the fixing disc 13, and a plurality of communication pipes 25 fixed to the top of the fixing disc 13, the bottom end of each communication pipe 25 extending into the annular cavity 24, and a suction disc 26 fixed in communication with the top end of each communication pipe 25. A fixing cylinder 27 is further fixed in the fixing disc 13, and the annular cavity 24 and the fixing cylinder 27 are in communication through a hose 28. A piston plate 29 is sealingly and slidably connected in the fixing cylinder 27, the top of the piston plate 29 being rotatably connected with a threaded rod 30, and the top end of the threaded rod 30 being threadedly penetrated through the fixing cylinder 27 and extending above the fixing cylinder 27.

[0062] In use, the bottom of the collecting bag is attached to the plurality of suction discs 26, and then the threaded rod 30 is rotated to drive the piston plate 29 to move upwards, so that the air in the annular cavity 24 is sucked into the fixing cylinder 27 to adsorb the collecting bag by the suction discs 26 and ensure the stability of the collecting bag.

[0063] The nursing device can stably fix the bottom disc 37 and the collecting bag of the ostomy bag through the cooperation of the fixing structure and the adsorption structure, and can uniformly spray the ostomy powder by combining the vibration and spraying functions of the nursing mechanism, so as to effectively promote the healing of the skin around the stoma and improve the life quality of the patient. The components are compact in structure and easy to operate, and have good practicability and operability.

[0064] With reference to Figure 6 and Figure 8The rotating ring 20 is made of medical-grade polypropylene material, and a plurality of semicircular notches 22 are uniformly distributed on the outer wall in the circumferential direction. The depth of the notch 22 is 2 mm, and the width is 3 mm. The top of the fixed disc 13 is fixed with a rubber column 23 by M3 bolts. The rubber column 23 is made of silicone rubber material with a hardness of 60A, and the top is a hemispherical structure with a diameter matching the width of the notch 22, which is 3 mm. The cooperation of the rubber column 23 and the notch 22 can withstand a reverse torque of ≥3N·m, avoiding the loosening of the pressing block 17.

[0065] When the rotating ring 20 rotates to the pressing block 17 completely presses the bottom disc 37, the rubber column 23 just embeds into the corresponding notch 22, which prevents the rotating ring 20 from rotating in the opposite direction through friction, ensuring the stable pressing of the bottom disc 37.

[0066] Referring to Figure 6 and Figure 7 , the bottom of the fixed disc 13 is embedded with a gas sensor 34 (model MQ-135) and a humidity sensor 35 (model DHT11). The sensor leads are routed through the wire slot inside the fixed disc 13. The water absorption pad 33 is made of high molecular water absorption resin (SAP) material, with a thickness of 5 mm, covering the skin contact area at the bottom of the fixed disc 13 and being fixed by medical adhesive. The gas sensor 34 and the humidity sensor 35 are used to detect whether the excrement is leaking in real time. When the excrement leaks, the water absorption pad 33 can quickly absorb the excrement to prevent its spread, while ensuring that the gas sensor 34 and the humidity sensor 35 can normally detect. The fixed disc 13 is uniformly distributed with six Z-shaped holes 31 in the circumferential direction, each with a hole diameter of 2 mm, and the bottom is communicated with the water absorption pad 33 through the air guide hole 32, which has a hole diameter of 1 mm. It ensures that the air can flow smoothly.

[0067] Referring to Figure 6 and Figure 7 , the alarm lamp 36 is fixed on the top of the fixed disc 13 by M2 bolts, using LED lamp beads, with a flickering frequency of 1 Hz, and is electrically connected with the sensor through the circuit on the PCB. The top of the fixed disc 13 is fixed with an alarm lamp 36 by bolts, and the alarm lamp 36 is electrically connected with the gas sensor 34 and the humidity sensor 35.

[0068] When the sensor detects that the ammonia concentration is ≥50 ppm or the humidity is ≥80% RH, the alarm lamp 36 is triggered to flash, and the data is uploaded to the hospital medical data sharing platform through the Bluetooth module (HC-05). After receiving the data, the platform sends a reminder message to the medical staff terminal that the ostomy bag needs to be replaced.

[0069] When the excrement leakage is detected, the alarm lamp 36 will issue a warning to prompt the user or medical staff to replace the ostomy bag in time. In addition, the gas sensor 34 and the humidity sensor 35 are both connected with the hospital medical data sharing platform through Bluetooth, realizing real-time transmission and sharing of data.

[0070] The sensor detection response time is less than or equal to 5 seconds, the alarm lamp 36 is triggered synchronously, and the false alarm rate is less than 0.1%.

[0071] The nursing device realizes stable fixation of the ostomy bag, real-time detection and alarm of excrement, air permeability adjustment between the fixing disc and the skin, and odor sealing when excrement leaks, effectively improving the quality of life of patients and reducing the work burden of medical staff. The compact structure of each component is simple and easy to operate, and has good practicality and operability.

[0072] Embodiment 2: Reference Figure 10 On the basis of Embodiment 1, the outer wall of the fixing disc 13 is sleeved with a sealing ring 39 for sealing the Z-shaped hole 31 when excrement leaks to avoid the odor spreading to the outside through the Z-shaped hole 31. The sealing ring 39 is made of medical polycarbonate material, and the inner diameter is gap-fitted with the outer diameter of the fixing disc 13 (gap 0.1 mm), and the height is 10 mm. The outer wall of the fixing disc 13 is also sleeved with a fixed ring 38 and a fixed ring 40, which are located below and above the sealing ring 39 respectively, for limiting the sealing ring 39. Six electromagnets 41 (model XDA-0530B) are embedded in the bottom of the fixed ring 40, and an iron sheet layer (thickness 0.5 mm) is attached to the corresponding position on the top of the sealing ring 39. When the humidity sensor 35 detects leakage, the electromagnets 41 are powered (voltage 12VDC) to generate a magnetic attraction force (≥5N) to attract the sealing ring 39 to move upward; when the sealing ring 39 moves upward to the bottom of the fixed ring 40, it completely covers the outer end opening of the Z-shaped hole 31, blocking the odor diffusion path.

[0073] After the sealing ring 39 moves upward, the odor blocking rate of the Z-shaped hole 31 reaches 99%, and the on-site odor intensity (CI value) decreases from level 4 to level 1.

[0074] After replacing the ostomy bag, disconnect the power supply of the electromagnets 41, manually push the sealing ring 39 down to the top of the fixed ring 38, and the Z-shaped hole 31 restores the air function.

[0075] The nursing method of the peristomal nursing device for postoperative colostomy of colorectal cancer includes the following steps:

[0076] S1, the fixing disc 13 is attached to the patient's abdomen by the cooperation of the waistband 14 and the magic tape 15, and the stoma is located at the center of the fixing disc 13. When nursing the stoma, first clean the surrounding area of the stoma with physiological saline, then apply ostomy powder and skin protection film;

[0077] S2, when the stoma powder is applied, the storage barrel 1 is placed on the top of the rotating ring 20, and the pin shaft 19 is inserted into the positioning groove 3 to position the positioning disc 2 and the storage barrel 1. At this time, the outer wall of the rubber wheel 7 is in contact with the top of the rotating ring 20. Then, the storage barrel 1 is manually driven to rotate, and the storage barrel 1 drives the rotating shaft 6 and the rubber wheel 7 to revolve. The friction between the rubber wheel 7 and the rotating ring 20 drives the rotating disc 8 to rotate. The rotating disc 8 drives the disc 5 to move up and down through the cooperation of the pin rod 9 and the rectangular groove 10, so that the stoma powder in the storage barrel 1 can be sprayed on the stoma area through the discharge port 12. In addition, the storage barrel 1 drives the disc 5 to rotate, so that the stoma powder can be uniformly sprayed on the surrounding area of the stoma.

[0078] S3, after the stoma powder and the skin protection film are applied, the bottom disc 37 of the stoma bag is pasted on the stoma area of the patient, and the stoma penetrates the bottom disc 37. In order to ensure the stability of the bottom disc 37 later, the rotating ring 20 is rotated at this time, and the rotating ring 20 drives the arc-shaped groove 21 to rotate. The pin shaft 19 is simultaneously in sliding cooperation with the arc-shaped groove 21 and the track groove 18. Therefore, when the rotating ring 20 rotates, the pin shaft 19 drives the pressing block 17 to move to the middle. The pressing block 17 can press on the top of the bottom disc 37 to press and fix the bottom disc 37, so as to avoid the falling of the bottom disc 37.

[0079] S4, in addition, after the bottom disc 37 and the collecting bag are installed, in order to ensure the stability of the collecting bag, the bottom of the collecting bag is attached to the plurality of suction cups 26 at this time. Then, the screw rod 30 is rotated to drive the piston plate 29 to move upwards, so that the air in the annular cavity 24 is sucked into the fixing cylinder 27. In this way, the suction cups 26 can be adsorbed to the collecting bag, so as to ensure the stability of the collecting bag.

[0080] S5, the cooperation of the Z-shaped hole 31 and the air guide hole 32 can ensure the air permeability between the fixing disc 13 and the skin. In addition, when the bottom disc 37 leaks, the excrement of the patient is contaminated. At this time, the water absorption pad 33 can absorb the excrement, which can not only avoid the diffusion of the excrement, but also enable the gas sensor 34 and the humidity sensor 35 to detect. The gas sensor 34 detects the ammonia or hydrogen sulfide generated by the decomposition of the excrement, so as to give an early warning of the leakage. The humidity sensor 35 can monitor the change of the humidity in real time. The humidity sensor 35 and the gas sensor 34 can transmit signals to the alarm lamp 36 and give a light alarm. The humidity sensor 35 and the gas sensor 34 can transmit signals to the hospital medical data sharing platform, so as to remind the patient and the medical staff to replace the stoma bag in time.

[0081] S6, in addition, when leakage occurs, the electromagnet 41 is electrified, and the electromagnet 41 generates a magnetic attraction force to the closed ring 39. The closed ring 39 moves upwards to close the Z-shaped hole 31, so as to avoid the smell of the excrement from spreading to the surrounding through the Z-shaped hole 31.

[0082] However, as known by those skilled in the art, the working principles and wiring methods of the gas sensor 34, the humidity sensor 35 and the alarm lamp 36 are common, which belong to conventional means or common general knowledge, and thus will not be described herein, and those skilled in the art can make any selection according to their needs or convenience.

[0083] The drawings in the specification of the present application are only of a schematic nature, and the sizes and shapes of the components shown are not actual limitations but only a schematic representation. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0084] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
