[0034] With reference to Figures 1 to 3 The present application discloses a filtering structure, comprising a connecting film 100, a water-blocking and air-permeable film 200, a filtering piece 300 and a water-blocking and air-permeable cloth 400 arranged in sequence, the edge of the connecting film 100 is connected with a bag body 500, so as to abut the water-blocking and air-permeable film 200, the filtering piece 300 and the water-blocking and air-permeable cloth 400 on the bag body 500, and the water-blocking and air-permeable cloth 400 abuts on the circumferential side of an air outlet 510 of the bag body 500, a window 110 for intestinal gas to pass through is arranged on the connecting film 100, the water-blocking and air-permeable film 200 and the water-blocking and air-permeable cloth 400 are both used for water-blocking and air-permeable, and the filtering piece 300 is used for filtering intestinal gas.

[0035] With reference to Figure 2 and Figure 3The water-resistant and air-permeable film 200 and the water-resistant and air-permeable cloth 400 are both air-permeable, and air can pass through the window 110, the water-resistant and air-permeable film 200, the filter 300, the water-resistant and air-permeable cloth 400, and the air outlet 510 in sequence, or pass through the air outlet 510, the water-resistant and air-permeable cloth 400, the filter 300, the water-resistant and air-permeable film 200, and the window 110 in sequence, so that the inner cavity of the bag 500 exchanges air with the outside, and then the intestinal gas in the bag 500 is discharged to the outside, that is, to the outside of the bag 500, which can avoid the bag 500 from swelling due to the accumulation of intestinal gas, or the air from the outside entering the bag 500, reducing the inconvenience of operating the bag 500 or the ostomy bag. When the bag 500 is pouring feces and urine, the speed of pouring feces and urine can be improved. When the intestinal gas passes through the filter 300, the filter 300 can absorb the peculiar smell gas in the intestinal gas, so that the intestinal gas discharged to the outside does not have a peculiar smell.

[0036] The water-resistant and air-permeable film 200 and the water-resistant and air-permeable cloth 400 both have hydrophobic and oleophobic properties, which can prevent water and oil components of excrement from penetrating the water-resistant and air-permeable film 200 and the water-resistant and air-permeable cloth 400, that is, can prevent the water and oil components in the bag 500 from leaking, and can also prevent water outside the bag 500 from entering the bag 500. Even when taking a shower, water will not enter the bag 500. When the filter structure is blocked by excrement such as feces and urine, the excrement can be removed from the water-resistant and air-permeable film 200 by pressing the entire filter structure, thereby restoring the air permeability of the entire filter structure.

[0037] Referring to Figure 2 and Figure 3 In some embodiments, the edges of the connecting film 100 are connected to the inner wall of the bag 500, and the water-resistant and air-permeable cloth 400 abuts against the inner wall of the bag 500, and the entire filter structure is arranged in the bag 500, so that the connection structure between the edges of the connecting film 100 and the bag 500 is not exposed outside the bag 500, the surface of the entire filter structure is smoother, the comfort is better, and the connection structure can be prevented from falling off due to being scratched by external components.

[0038] In some embodiments, the edges of the connecting film 100 are connected to the inner wall of the bag 500 by a hot melting method. The hot melting processing method utilizes the characteristics of the materials of the connecting film 100 and the bag 500, and can tightly connect the connecting film 100 and the bag 500 without adding external materials such as glue, and the processing method is simple and low in cost, and the sealing performance of the connection between the connecting film 100 and the bag 500 is very good.

[0039] In some embodiments, the water-proof and air-permeable cloth 400 is connected to the periphery of the exhaust port 510 of the bag 500, so that a connection is formed between the water-proof and air-permeable cloth 400 and the bag 500, and the connection has a sealing effect, ensuring that intestinal gas can only move along the track of the water-proof and air-permeable cloth 400 and the exhaust port 510.

[0040] In some embodiments, the water-proof and air-permeable cloth 400 is connected to the periphery of the exhaust port 510 of the bag 500 by means of hot melting.

[0041] It is conceivable that the periphery of the window 110 of the connecting film 100 is connected to the water-proof and air-permeable film 200, and the water-proof and air-permeable film 200 and the water-proof and air-permeable cloth 400 are clamped and positioned to the filter 300.

[0042] In some embodiments, the filter 300 is an activated carbon bag, and the activated carbon in the activated carbon bag has very good odor adsorption effect. The activated carbon bag is a common component on the market, and will not be described redundantly here.

[0043] In some embodiments, the connecting film 100, the water-proof and air-permeable film 200, the filter 300 and the water-proof and air-permeable cloth 400 are all in the shape of a square, which is convenient to process and low in cost. Of course, the connecting film 100, the water-proof and air-permeable film 200, the filter 300 and the water-proof and air-permeable cloth 400 can also all be in the shape of a circular cake.

[0044] With reference to Figure 1 The utility model discloses a stoma bag, including bag 500 and above-mentioned filter structure, and filter structure sets up on bag 500.

[0045] The stoma bag has all the beneficial effects brought by the filter structure of the above-mentioned embodiments, which will not be repeated here.

[0046] In some embodiments, the bag 500 includes a front surface and a back surface, and the back surface is provided with a base plate. The bag 500 is attached to the abdominal skin through the base plate. An inlet is provided on the bag 500, and an opening is provided on the base plate. The inlet, the opening and the inner cavity of the bag 500 are sequentially connected. The filter structure is provided on the front surface, and the projection of the filter structure on the back surface is above the base plate. Intestinal gas is discharged to the outside of the bag 500 through the filter structure.

[0047] With reference to Figure 1 In some embodiments, an outlet is provided on the bag 500. Through the outlet, feces, urine and other pollutants in the bag 500 can be discharged to the outside of the bag 500, and the dumping of feces, urine and the like is completed.

[0048] The bag body 500 is provided with a sealing device structure, which is used for sealing the outlet.

[0049] The connecting film 100, the water-resistant and air-permeable film 200, the water-resistant and air-permeable cloth 400 and the bag body 500 are all made of common materials and belong to common components.

[0050] The technical features of the above embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that the range is recorded in the specification.

[0051] Of course, the utility model is not limited to the above-mentioned implementation, the skilled person in the art can also make equivalent transformation or replacement without departing from the spirit of the utility model, and these equivalent transformations or replacements are all included in the range defined by the claims of the present application.
