Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to an anti-extrusion ostomy bag. Background Art

[0002] Clinically, some digestive tract diseases such as intestinal necrosis and tumors can hinder the digestion of food through the intestine. In this case, enterostomy can bypass the obstruction by establishing a new channel so that food can pass normally. Enterostomy is a common operation in clinical practice. It usually requires pulling out a section of the intestine in the abdominal cavity, and then putting an ostomy bag on the pulled-out intestine. Excreting feces into the ostomy bag through an opening in the skin of the abdominal wall can improve the patient's disease and prevent the disease from continuing to develop.

[0003] The ostomy bag in the prior art often causes liquid reflux due to external force when in use, leading to stoma inflammation and infection. In addition, since the gas in the intestine will enter the ostomy bag, if it is not discharged in time, it will cause the bag to swell. Therefore, to address the above problems, we propose an anti-squeezing ostomy bag. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide an anti-squeezing ostomy bag. When the ostomy bag is squeezed by external force, there will be no problem of liquid reflux, thus avoiding stoma inflammation and infection. Moreover, when there is a lot of gas in the ostomy bag, the gas can be exhausted to avoid the expansion and leakage of the ostomy bag.

[0005] To achieve the above objectives, the utility model adopts the following technical solution: an anti-extrusion ostomy bag, comprising an ostomy bag body, wherein the upper end of the ostomy bag body is connected to a drainage tube for draining feces, the end of the drainage tube away from the ostomy bag body is connected to an adhesive plate, a sealing portion is provided on the drainage tube, the sealing portion is located between the ostomy bag body and the adhesive plate, a sealing component is provided in the sealing portion, the sealing component comprises a sealing ring and a sealing plate, the top of the sealing ring is connected to the top inner wall of the sealing portion, the sealing plate is located below the sealing ring, a spring is connected between the bottom surface of the sealing plate and the bottom inner wall of the sealing portion, a filter tube is provided at the upper end of the ostomy bag body, a filter element is provided in the filter tube, the filter element is used to filter and discharge the liquid in the ostomy bag body, and the bottom of the ostomy bag body is connected to a sewage discharge pipe.

[0006] The beneficial effects of the utility model are as follows: the drainage tube is adhered to the stoma opening through the adhesive plate, and feces is discharged into the interior of the stoma bag body through the drainage tube; when the stoma bag body is squeezed, the blocking component blocks the drainage tube to prevent liquid reflux and stoma inflammation and infection; at the same time, gas can be filtered and discharged from the filter tube by the filter element to prevent the stoma bag body from expanding and leaking.

[0007] In order to discharge the gas in the ostomy bag body;

[0008] As a further improvement of the above technical solution: the filter element includes a filter layer and an activated carbon layer, and the filter tube has a filter layer and an activated carbon layer in sequence from the ostomy bag body to the filter tube opening, and a sealing cap is threadedly connected to the filter tube.

[0009] The beneficial effect of this improvement is that when the gas in the ostomy bag body needs to be discharged, the gas is filtered through the filter layers in turn by squeezing the ostomy bag body, and then the activated carbon layer adsorbs the toxic substances in the gas, and then the filter tube is blocked by the blocking cap to avoid contamination of the filter element.

[0010] In order to make the drainage tube completely airtight;

[0011] As a further improvement of the above technical solution: a sealing convex ring is provided at the bottom of the sealing disk, and a sealing groove matched with the sealing convex ring is provided at the bottom of the sealing ring.

[0012] The beneficial effect of this improvement is that when the ostomy bag body is squeezed, the sealing disk is squeezed by the gas, so that the sealing disk moves upward to squeeze the sealing ring, and at the same time the sealing convex ring is clamped into the sealing groove to completely seal the drainage tube.

[0013] To prevent feces from falling on the blocking disc;

[0014] As a further improvement of the above technical solution: a guide portion is provided above the sealing disk, and the guide portion is conical in shape.

[0015] The beneficial effect of this improvement is that when feces flows into the stoma bag body from the stoma, the feces falls on the sealing disk. At this time, due to the setting of the guide part, the feces flows down from the guide part and enters the inside of the stoma bag body.

[0016] In order to discharge the feces inside the ostomy bag body;

[0017] As a further improvement of the above technical solution: a valve is provided on the waste discharge pipe.

[0018] The beneficial effect of this improvement is that when the feces in the ostomy bag body needs to be discharged, the valve is opened, and the feces inside the ostomy bag body flows out from the waste discharge pipe.

[0019] In order to reinforce the ostomy bag body;

[0020] As a further improvement of the above technical solution: both sides of the ostomy bag body are provided with straps, and the two straps are detachably connected via a connecting piece.

[0021] The beneficial effect of this improvement is that by fixing the strap on the patient's body, the ostomy bag body can be reinforced, and at the same time, the pressure on the patient when the ostomy bag body falls can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the ostomy bag body 1 is connected to a waste discharge pipe 9, wherein the ostomy bag body 1 and the adhesive plate 3 are both prior arts and will not be described in detail herein. By fixing the adhesive plate 3 at the stoma of the patient, and then draining the feces into the ostomy bag body 1 through the drainage tube 2, when the ostomy bag body 1 is squeezed by an external force, the gas in the ostomy bag body 1 will be squeezed into the drainage tube 2, and then the gas squeezes the blocking plate 502, so that the blocking plate 502 moves up and is tightly attached to the blocking ring 501, and at the same time, the gas is filtered and discharged through the filter element, and when the ostomy bag body 1 is not squeezed, the spring 6 is elastic. Under the action of the plugging disk 502, the plugging disk 502 is restored to its original position, and the feces continues to flow into the interior of the ostomy bag body 1 through the drainage tube 2 from the gap between the plugging ring 501 and the plugging disk 502; the filter element includes a filter layer 801 and an activated carbon layer 802, and the filter tube 7 is provided with the filter layer 801 and the activated carbon layer 802 in the direction from the ostomy bag body 1 to the filter tube 7 mouth in sequence, and the filter tube 7 is threadedly connected with a plugging cap 10, wherein the filter layer 801 is a microporous membrane filtration structure, and when the gas in the ostomy bag body 1 needs to be discharged, the ostomy bag body 1 is squeezed, and the gas is filtered through the filter layer 801 in sequence, and then the activated carbon layer 802 adsorbs the toxic substances in the gas, and then the plugging cap 10 adsorbs the toxic substances in the gas. The filter tube 7 is blocked to avoid contamination of the filter element; a sealing convex ring 11 is provided at the bottom of the blocking disk 502, and a sealing groove 12 matched with the sealing convex ring 11 is provided at the bottom of the blocking ring 501. When the ostomy bag body 1 is squeezed, the blocking disk 502 is squeezed by the gas, so that the blocking disk 502 moves upward to squeeze the blocking ring 501, and the sealing convex ring 11 is stuck in the sealing groove 12, so that the drainage tube 2 is completely closed; a guide part 13 is provided above the blocking disk 502, and the guide part 13 is conical. When feces flows into the ostomy bag body 1 from the stoma, the feces falls on the blocking disk 502. At this time, due to the setting of the guide part 13, the feces flows down from the guide part 13 and enters the inside of the ostomy bag body 1;The waste discharge pipe 9 is provided with a valve 14. When the feces in the ostomy bag body 1 needs to be discharged, the valve 14 is opened, and the feces in the ostomy bag body 1 flows out from the waste discharge pipe 9. Both sides of the ostomy bag body 1 are provided with straps 15. The two straps 15 are detachably connected by a connector, wherein the connector can be a Velcro, a snap-on buckle or the like.

When the feces passes through the blocking component, the feces flows down from the middle of the blocking ring 501 and around the blocking plate 502. At the same time, the setting of the guide part 13 prevents the feces from staying on the blocking plate 502. When an external force acts on the ostomy bag body 1 and squeezes the ostomy bag body 1, the gas in the ostomy bag body 1 will be squeezed upward, and then squeeze the blocking plate 502. 2, move the sealing disk 502 upward, and at the same time, insert the sealing convex ring 11 into the sealing groove 12, and then seal the drainage tube 2 to prevent the liquid inside the ostomy bag body 1 from flowing back and polluting the stoma. When it is necessary to discharge the gas inside the ostomy bag body 1, open the sealing cap 10, squeeze the ostomy bag body 1, and at the same time, the sealing assembly seals the drainage tube 2, and then the gas is discharged from the filter tube 7. The gas is filtered by the filter layer 801 and adsorbed by the activated carbon layer 802, which reduces the pollution of the gas to the air. Then, the sealing cap 10 is screwed on the filter tube 7 to avoid contamination of the filter element. Finally, when it is necessary to discharge the feces in the ostomy bag, open the valve 14, and the feces is discharged from the waste discharge pipe 9.
