[0020] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0021] It should be noted that Figures 1 to 3 The dashed arrow in the figure represents the direction of the force.

[0022] Reference Figures 1 to 3 The present invention discloses an ostomy bag, including a bag body 100, a first elastic sheet 200, a second elastic sheet 300, a first actuating part 400, a second actuating part 500, a third actuating part 600 and a fourth actuating part 700.

[0023] The bag body 100 includes a front membrane sheet 110 and a rear membrane sheet 120. Both the front membrane sheet 110 and the rear membrane sheet 120 are made of soft films and can be deformed under the action of external force or its own gravity. After the external force is removed and after support is obtained, the shape of the film will remain unchanged.

[0024] The front film 110 and the rear film 120 enclose an inner cavity, and a downward outlet 130 is formed between the lower ends of the front film 110 and the rear film 120, and an inlet is provided on the rear film 120, and a bottom plate 122 is connected to the rear film 120, and a scissor hole is provided on the bottom plate 122, and the bottom plate 122 is used to be attached to the abdominal skin, and the scissor hole, the inlet and the inner cavity of the bag body 100 are connected. When using the ostomy bag, an opening matching the size of the stoma can be cut on the bottom plate 122 through the scissor hole, and the bottom plate 122 is attached to the abdominal skin, and the opening and the stoma are connected, and the excrement discharged from the stoma can enter the inner cavity of the bag body 100 through the opening and the inlet.

[0025] The edge of the front diaphragm 110 and the edge of the rear diaphragm 120 are connected by welding or hot melting, and the welding or hot melting area has good sealing. There is no welding between the lower edge of the edge of the front diaphragm 110 and the lower edge of the edge of the rear diaphragm 120, thereby forming an outlet 130.

[0026] Reference Figures 1 to 3The first spring piece 200 is arranged on the rear side of the rear diaphragm 120; the second spring piece 300 is arranged on the front side of the front diaphragm 110, the length directions of the first spring piece 200 and the second spring piece 300 are extended in the left-right direction, the length of the first spring piece 200 is greater than the length of the second spring piece 300, the second spring piece 300 and the first spring piece 200 are staggered up and down and the first spring piece 200 is located below the second spring piece 300; the first actuating portion 400 is the left end of the first spring piece 200; the second actuating portion 500 is the right end of the first spring piece 200; the third actuating portion 600 is the area on the front diaphragm 110 corresponding to the center of the first spring piece 200; the fourth actuating portion 700 is the area on the rear diaphragm 120 corresponding to the center of the second spring piece 300.

[0027] It should be understood that when there is less excrement in the bag body 100, the front membrane 110 and the rear membrane 120 tend to stick together in the area corresponding to the outlet 130, and it is difficult to open the outlet 130 by relying on the gravity of the excrement, especially when there is liquid in the front membrane 110 and the rear membrane 120 corresponding to the outlet 130, a certain external force is required to open the outlet 130, that is, external force is required to open the front membrane 110 and the rear membrane 120.

[0028] When dumping excrement, the first actuating portion 400 and the second actuating portion 500 are suitable for being clamped toward each other, the third actuating portion 600 is pushed backward to make the center of the first elastic sheet 200 bend backward, the third actuating portion 600 releases the push, the center of the first elastic sheet 200 remains in a state of bending backward, the fourth actuating portion 700 is pushed forward to make the center of the second elastic sheet 300 bend forward, and the first actuating portion 400 and the second actuating portion 500 are further clamped toward each other to make the front diaphragm 110 and the rear diaphragm 120 open, so that the excrement in the bag body 100 can be easily dumped, and the opening of the front diaphragm 110 and the rear diaphragm 120 facilitates cleaning the interior of the bag body 100.

[0029] It can be understood that the thumb and middle finger of the left hand can be used to press against the first actuating part 400 and the second actuating part 500 respectively, and then the thumb and the middle finger are pinched together to bring the first actuating part 400 and the second actuating part 500 closer to each other, and the index finger is hooked back on the third actuating part 600 and pulls back the front diaphragm 110 and the central area of ​​the first elastic sheet 200, so that the central area of ​​the first elastic sheet 200 bends backward, and then the index finger is removed, and the index finger is no longer pressed against the front diaphragm 110, that is, the push on the third actuating part 600 is released. At this time, the center of the first elastic sheet 200 remains in a state of bending backward. Then the index finger is pressed against the fourth actuating part 700 and pushes the center of the second elastic sheet 300 forward, so that the center area of ​​the second elastic sheet 300 bends forward, and the thumb and the middle finger continue to pinch, so that the first actuating part 400 and the second actuating part 500 are further approached to each other, and the center area of ​​the first elastic sheet 200 is further bent backward, so that the front diaphragm 110 and the rear diaphragm 120 are opened, and the outlet 130 is opened. The above operation is completed by one hand, and the operation is convenient and quick.

[0030] The first spring piece 200 and the second spring piece 300 respectively drive the rear diaphragm 120 and the front diaphragm 110, and the rear diaphragm 120 and the front diaphragm 110 move away from each other, thereby realizing the opening or spreading of the outlet 130. The first spring piece 200 and the second spring piece 300 act as a skeleton to prop open the outlet 130, which is convenient for dumping excrement, and the spread outlet 130 is conducive to pouring in cleaning liquid and inserting cleaning tools, so as to facilitate cleaning the interior of the bag body 100.

[0031] The first spring sheet 200 and the second spring sheet 300 are elastic and can quickly return to a flat shape after being bent. The first spring sheet 200 and the second spring sheet 300 can be made of plastic. The length of the first spring sheet 200 is slightly shorter than the front diaphragm 110 and the rear diaphragm 120 at the outlet 130.

[0032] Reference Figure 2 In some embodiments, the ostomy bag further includes a fifth actuating portion 800 and a sixth actuating portion 900 , wherein the fifth actuating portion 800 is the left end of the second elastic piece 300 ; and the sixth actuating portion 900 is the right end of the second elastic piece 300 .

[0033] The first actuating portion 400 and the second actuating portion 500 are further clamped toward each other, and the first actuating portion 400 and the second actuating portion 500 continue to approach each other, and the fifth actuating portion 800 and the sixth actuating portion 900 are suitable for being clamped toward each other, and the fifth actuating portion 800 and the sixth actuating portion 900 make the central area of ​​the second elastic sheet 300 bend further forward, thereby making the front diaphragm 110 and the rear diaphragm 120 further open, and the fourth actuating portion 700 releases the push again.

[0034] It can be understood that when the thumb and the middle finger are respectively pressed against the first actuating part 400 and the second actuating part 500, the thumb and the middle finger are simultaneously pressed against the fifth actuating part 800 and the sixth actuating part 900, respectively. That is, during specific operation, the first actuating part 400 and the fifth actuating part 800 are both operated by the thumb, and the second actuating part 500 and the sixth actuating part 900 are both operated by the middle finger.

[0035] The first elastic sheet 200 is located below the second elastic sheet 300, that is, the first elastic sheet 200 is closer to the opening of the outlet 130 than the second elastic sheet 300. The first elastic sheet 200 is arranged at the rear side of the rear membrane 120, and the second elastic sheet 300 is arranged at the front side of the front membrane 110, so that the inner wall of the outlet 130 remains smooth, and the inner wall of the outlet 130 here refers to the rear side of the lower end of the front membrane 110 and the front side of the lower end of the rear membrane 120. When dumping excrement, the rear membrane 120 is usually located below the front membrane 110, and the rear membrane 120 at the outlet 130 is supported by the first elastic sheet 200 to prevent the rear membrane 120 at the outlet 130 from being soft, so as to facilitate observation and cleaning of the inner wall of the outlet 130.

[0036] In some of the embodiments, the front membrane 110 and the rear membrane 120 are both made of transparent materials, so that the situation inside the bag body 100 can be directly observed, thereby knowing the condition of the excrement in the bag body 100, such as the amount, color and presence of foreign matter of feces and urine.

[0037] In some embodiments, the first spring piece 200 and the second spring piece 300 are made of white material, and the excrement is clearly visible against the background of the white material. The first spring piece 200 and the second spring piece 300 are respectively arranged on the front film 110 and the rear film 120 corresponding to the outlet 130, so it can be clearly observed whether there is excrement residue on the front film 110 and the rear film 120 corresponding to the outlet 130, thereby confirming whether the outlet 130 is clean. Of course, the first spring piece 200 and the second spring piece 300 can also be made of skin-colored material.

[0038] When the outlet 130 needs to be closed / sealed, the front diaphragm 110 and the rear diaphragm 120 can be folded multiple times from bottom to top around the first elastic sheet 200 and the second elastic sheet 300 to form a folded package having a multi-channel sealing structure to improve the sealing performance of the outlet 130 .

[0039] Reference Figure 3In some embodiments, the ostomy bag further includes a male Velcro 121 and a female Velcro 111, which are respectively arranged on the rear side of the rear film 120 and the front side of the front film 110. When the male Velcro 121 and the female Velcro 111 are attached, they can bind the folded bag to prevent the folded bag from spreading, thereby fixing the outlet 130. In another embodiment, the positions of the male Velcro 121 and the female Velcro 111 are interchanged.

[0040] The operation of closing / sealing the outlet 130 is as follows: the first spring sheet 200 drives the front diaphragm 110 and the rear diaphragm 120 to fold onto the second spring sheet 300, and then the first spring sheet 200 and the second spring sheet 300 continue to fold twice. At this time, the male Velcro 121 and the female Velcro 111 are close to each other, and the male Velcro 121 and the female Velcro 111 are buckled together, and the male Velcro 121 and the female Velcro 111 can bind the folded bag.

[0041] It can be imagined that the male Velcro 121 and the female Velcro 111 are both above the first elastic sheet 200 and the second elastic sheet 300. In this embodiment, a transfer film is connected to the front side of the front membrane 110, and the upper end of the transfer film is connected to the female Velcro 111, and the female Velcro 111 is connected to the front side of the front membrane 110 through the transfer film.

[0042] Reference Figure 2 and Figure 3 In some embodiments, a storage bag 112 with the bag opening facing upward is provided on the front side of the front membrane 110, and the storage bag 112 is used to store the male Velcro 121, the female Velcro 111 and the folding bag. After the male Velcro 121 and the female Velcro 111 are bundled with the folding bag, the male Velcro 121, the female Velcro 111 and the folding bag are placed in the storage bag 112 to prevent the male Velcro 121, the female Velcro 111 and the folding bag from being exposed, that is, to prevent the male Velcro 121, the female Velcro 111 and the folding bag from rubbing or scratching the skin, thereby improving the comfort of the ostomy bag.

[0043] It is understandable that the front side of the front film 110 is connected with a connecting film, and the front film 110 and the connecting film form a storage bag 112 with the bag opening facing upward. When the male Velcro 121, the female Velcro 111 and the folding bag need to be stored, the storage bag 112 is turned up from the bottom so that the inner wall of the storage bag 112 and the outer wall of the storage bag 112 are interchanged, and the storage bag 112 is turned over so that the outer wall of the storage bag 112 wraps the male Velcro 121, the female Velcro 111 and the folding bag.

[0044] The connecting film may be a non-woven fabric. The lower end, the left end and the right end of the connecting film are all connected to the front side of the front film sheet 110 to form a storage bag 112 with the bag opening facing upward.

[0045] Reference Figure 2In some embodiments, the front membrane 110 is provided with an exhaust port, through which the intestinal gas in the inner cavity can be discharged to the outside of the bag body 100. A filter structure 113 for filtering intestinal gas is provided in the exhaust port, and the filter structure 113 can remove odorous gas and prevent intestinal gas from contaminating the air outside the bag body 100.

[0046] The filter structure 113 has a breathable function. Both intestinal gas and external air can pass through the filter structure 113 to adjust the air pressure in the inner cavity. The intestinal gas is discharged in time to prevent the bag body 100 from swelling due to intestinal gas. The external air enters the inner cavity, reducing the air pressure difference between the inner cavity and the outside world, so that the excrement can be dumped smoothly.

[0047] The filter structure 113 has a hydrophobic combing effect, which can prevent the oil and water of the excrement from passing through the filter structure 113.

[0048] In some of the embodiments, a skin-contacting layer is provided on the rear membrane 120, and the skin-contacting layer is used to contact the abdominal skin to prevent other parts of the ostomy bag from rubbing against the skin, thereby improving the comfort of the entire ostomy bag.

[0049] It is understandable that the skin-contacting layer covers the rear side of the entire rear membrane 120. The skin-contacting layer can be a non-woven fabric or a polyester fabric.

[0050] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
