Description

Technical Field

[0001] The present invention belongs to the technical field of stoma, and particularly relates to a stoma device capable of reducing odor. Background Art

[0002] Since there are two layers of sphincter muscles around the anus of the human body, which can control the excretion of feces; however, after stoma surgery, the function of the anus disappears, and the so-called artificial anus does not have sphincter muscles, and the discharge of feces is not controlled. Therefore, a stoma device must be used to avoid the embarrassment and inconvenience during feces discharge. Currently, there are two types of stoma devices on the market, namely one-piece ostomy bags and two-piece ostomy bags. Among them, the two-piece ostomy bag is better accepted by patients because it causes less harm to the patient's stoma when replacing the bag body. However, in the existing two-piece stoma device, there is still a certain gap at the connection between the bag body and the chassis after connection, so that the odor gas discharged by the patient is easy to leak from the connection gap. And when discharging the odor gas, the current method is to directly open the sealing cover on the bag body for discharge, and the odor gas cannot be processed, which is likely to cause certain embarrassment and inconvenience to the wearing patient. Therefore, designing a stoma device capable of reducing odor can reduce the leakage of odor and can filter and purify the odor to a certain extent to solve the above problems.

[0030] The odor treatment and emission mechanism 3 includes a treatment box 31, a socket 32, an activated carbon adsorption and purification block 33, a conduit 34, a connecting soft sleeve 35 and a spring 36. The lower part of the socket 32 is movably inserted into the treatment box 31. The activated carbon adsorption and purification block 33 is clamped in the socket 32. One end of the conduit 34 movably penetrates through the side wall of one side of the treatment box 31. The spring 36 is sleeved on the conduit 34 in the treatment box 31. The connecting soft sleeve 35 is sleeved and fixed at one end of the conduit 34 outside the treatment box 31. A clamping groove for clamping the activated carbon adsorption and purification block 33 is opened in the horizontal direction at the lower part of the socket 32, and the activated carbon adsorption and purification block 33 can be horizontally inserted into the socket 32. Through the activated carbon adsorption and purification block 33, the odor entering the treatment box 31 can be filtered and purified, and thus the odor generated at the stoma of the patient can be reduced through this stoma device.

[0031] The circumferential side wall of the socket 32 is in contact with the inner side wall of the treatment box 31, which can effectively prevent the leakage of peculiar smell from the gap between the socket 32 and the treatment box 31, and can further reduce the leakage of peculiar smell. A top cover 321 is provided at the top of the socket 32. The lower part of the top cover 321 is stuck on the treatment box 31, and an opening and closing notch is provided on one side of the top cover 321. Through the provided opening and closing notch, the socket 32 can be taken out from the card slot of the treatment box 31, and then the activated carbon adsorption and purification block 33 in the socket 32 can be taken out to clean or replace the activated carbon adsorption and purification block 33. An exhaust grille is provided at the top of the socket 32. Through grooves are vertically formed in the socket 32 and communicated with the exhaust grille. The gas purified by the activated carbon adsorption and purification block 33 can finally be discharged from the exhaust grille at the top of the socket 32.

[0032] The treatment box 31 is fixedly connected to the chassis 1. A sealing vertical plate 311 is vertically and fixedly arranged in the treatment box 31 below the socket 32. A connecting circular plate 341 is arranged at one end of the conduit 34 inside the treatment box 31, and a rubber ring is embedded and fixed on the end face of the connecting circular plate 341. The connecting circular plate 341 abuts against the sealing vertical plate 311. Through the provided rubber ring, effective sealing between the connecting circular plate 341 and the sealing vertical plate 311 can be achieved, so that the discharge of the peculiar smell in the bag body 4 can be controllable. External threads are provided at one end of the conduit 34 outside the treatment box 31. The connecting soft sleeve 35 has a certain elasticity. One end of the connecting soft sleeve 35 is fixedly connected to the outer side wall of the conduit 34, and the other end of the connecting soft sleeve 35 is fixedly connected to the outer side wall of the treatment box 31. Through the provided connecting soft sleeve 35, the connecting gap between the conduit 34 and the treatment box 31 can be effectively sealed, and the leakage of peculiar smell from the gap between the treatment box 31 and the conduit 34 can be avoided, reducing the emission of peculiar smell. One end of the spring 36 is fixedly connected to the connecting circular plate 341, and the other end of the spring 36 is fixedly connected to the inner side wall of the treatment box 31. Through the provided spring 36, the connecting circular plate 341 can be automatically and effectively attached to the sealing vertical plate 311, and the controllability of the peculiar smell discharge can be achieved.

[0033] An observation window 41 is provided at the upper part of the front surface of the bag body 4. Through the provided observation window 41, the excrement of the stoma patient in the bag body 4 can be viewed, and the bag body 4 can be removed and replaced in a timely manner. At the lower part of the back surface of the bag body 4, fixing cards 11 are symmetrically and fixedly connected. The two fixing cards 11 are connected in cooperation with the two connecting card seats 7 on the chassis 1, and the fixing cards 11 are stuck on the connecting card seats 7. By correspondingly sticking the two fixing cards 11 on the two connecting card seats 7, an effective connection can be achieved between the lower part of the bag body 4 and the chassis 1. The air guide hose 8 is communicated with the inside of the bag body 4. One end of the connecting head 81 of the air guide hose 8 is threadedly connected with one end of the conduit 34 located outside the treatment box 31. Through the air guide hose 8, the odor gas in the bag body 4 can be introduced into the odor treatment and discharge mechanism 3, and the odor can be filtered, purified and discharged through the odor treatment and discharge mechanism 3.

[0034] At the upper part of the connecting seat 9, connecting ears 91 are symmetrically arranged. Connecting grooves 911 are provided on the connecting ears 91. The two movable clamping arms 27 on the locking and connecting mechanism 2 are respectively connected in cooperation with the connecting grooves 911 on the two connecting ears 91. The lower ends of the two movable clamping arms 27 respectively penetrate through the connecting grooves 911 on the two connecting ears 91 correspondingly. When connecting the bag body 4 to the chassis 1, by adjusting the two movable clamping arms 27, the lower ends of the two movable clamping arms 27 can respectively penetrate through the connecting grooves 911 on the connecting ears 91, and thus the upper part of the bag body 4 can be quickly connected and fixed to the chassis 1, which is convenient for personnel to replace the bag body 4.

[0035] Working principle: When using this stoma device, the back of the chassis 1 can be adhesively fixed on the abdomen at the stoma of the patient through a medical adhesive, and the stoma sleeve 5 is sleeved on the stoma. Then, the handheld bag body 4 is used, and the connecting seat 9 is aligned with the stoma sleeve 5 and sleeved on the stoma sleeve 5, so that the rubber annular sealing protrusion 10 on the inner wall of the connecting seat 9 is stuck in the annular sealing groove 51 on the outer wall of the stoma sleeve 5. Then, the adjusting wheel 21 on the locking connection mechanism 2 can be manually rotated to drive the rotating shaft 23 to rotate. The rotation of the rotating shaft 23 can drive the driving bevel gear 24 to rotate. The rotation of the driving bevel gear 24 can drive the driven bevel gear 25 to rotate. The rotation of the driven bevel gear 25 can drive the adjusting screw 26 to rotate. The rotation of the adjusting screw 26 can drive the two movable clamping arms 27 to rotate downward through the connecting teeth 271, and the lower ends of the two movable clamping arms 27 respectively penetrate through the connecting grooves 911 on the two connecting ears 91, so that the upper part of the bag body 4 can be fixed on the chassis 1. Then, the two fixing clips 11 at the lower part of the bag body 4 can be respectively clamped on the two connecting card seats 7 at the lower part of the front surface of the chassis 1, and the connecting head 81 at one end of the air guide hose 8 is screwed on the end of the conduit 34 on the odor treatment and discharge mechanism 3, so that this stoma device can be fixed at the stoma site of the patient. The excrement generated by the patient can be collected through the bag body 4. The amount of excrement in the bag body 4 can be observed through the observation window 41, and the bag body 4 can be timely removed and replaced from the chassis 1. Through the cooperation of the annular sealing groove 51 and the rubber annular sealing protrusion 10, the odor of excrement can be effectively prevented from leaking from the connection gap between the stoma sleeve 5 and the connecting seat 9;

[0036] When there is excretory gas in the bag body 4 that needs to be discharged in time, at this time, the patient can pinch the connection part of the conduit 34 and the connecting head 81 by hand and pull the conduit 34 outward. At this time, the conduit 34 moves outward, which can separate the connecting circular plate 341 from the sealing vertical plate 311 and can compress the spring 36 at the same time. At this time, the odor-containing gas in the bag body 4 can be introduced into the treatment box 31 in the odor treatment and discharge mechanism 3 through the air guide hose 8 and the conduit 34. The odor gas entering the treatment box 31 can move upward and is finally discharged from the exhaust grille at the top of the top cover 321 after being adsorbed, filtered and purified by the activated carbon adsorption and purification block 33. During this process, the odor can be reduced by the activated carbon adsorption and purification block 33. After the gas in the bag body 4 is discharged, the conduit 34 is released. At this time, under the elastic force of the spring 36, the connecting circular plate 341 can be driven to automatically move towards the sealing vertical plate 311 and fit tightly with the sealing vertical plate 311.
