Description

Technical Field

[0001] This invention relates to the field of stoma bag technology, and in particular to a storage bag type stoma bag device and its usage method. Background Technology

[0002] In the field of cancer, the incidence of colorectal cancer is rising year by year, seriously threatening people's quality of life and social development. Among them, patients with rectal cancer, especially low rectal cancer, often face the dilemma of not being able to preserve their anus. With current technology, the only way to save their lives is through sigmoid colonostomy. During the operation, it is generally necessary to create a fistula in the patient's side wall and use a stoma bag to solve the patient's excretion problem.

[0003] Existing disposable stoma base plates and collection bags can only be used once, and both require the base plate to be peeled off the skin, which can easily damage the skin and the stomated intestine. Another type of stoma device with replaceable bags has a difficult-to-align locking mechanism, making it prone to detachment. Installation and removal are cumbersome, and patients cannot operate them themselves, requiring assistance from family members. Changing the stoma bag is also extremely inconvenient. Both of these stoma devices expose the intestines and excrement each time they are changed, resulting in a strong odor. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0042] Currently, disposable stoma base plates and collection bags can only be used once. After each use, the base plate needs to be peeled off the skin, which can easily damage the skin and the stoma's intestinal tract. In addition, each time it is changed, the intestines and excrement are exposed, resulting in a strong odor.

[0043] In view of this, such as Figures 1-4 As shown, the stoma bag device 1 provided in this embodiment of the invention includes: a stoma bag 1, a stoma ring 2, a locking mechanism 5, and a cutting mechanism 9; the stoma ring 2 has a through hole in the middle, and the stoma ring 2 is detachably connected to the patient's stoma; the stoma ring 2 has an annular receiving space, and the stoma bag 1 is placed in the receiving space, and the stoma bag 1 is slidably connected to the receiving space so that the stoma bag 1 can extend out through the receiving space; the locking mechanism 5 is disposed on the stoma ring 2, and the locking mechanism 5 is connected to the stoma ring 2 and detachably connected to the stoma bag 1, and the locking mechanism 5 can lock the stoma bag 1 so that the stoma bag 1 is fixed; the cutting mechanism 9... Located on one side of the stoma bag 1, the cutting mechanism 9 is used to cut and seal the stoma bag 1. When the stoma bag 1 needs to be replaced, it is separated from the stoma bag 1 by the locking mechanism 5, and the stoma bag 1 is pulled out from the accommodating space to increase the accommodating volume of the stoma bag 1. Then, the cutting mechanism 9 cuts and seals the stoma bag 1, so that the stoma bags 1 on both sides are sealed to prevent the emission of odor. There is no need to remove the stoma ring 2, which alleviates the technical problems of easily damaging the skin and intestines when changing the collection bag, while exposing excrement and intestines, and causing a large odor. It achieves the technical effect of avoiding the exposure of excrement and intestines, removing odor, and not easily damaging the skin and intestines.

[0044] Regarding the structure and shape of stoma bag 1, specifically:

[0045] The stoma bag 1 can be made of flexible material or tough material. The stoma bag 1 is rolled into a ring shape in the accommodating space. Both ends of the stoma bag 1 can be set as sealed. The stoma bag 1 can be heat-melted so that it can be sealed by the cutting mechanism 9. The stoma bag 1 can be made of opaque material, with transparent windows set at intervals of 30cm to prevent the excrement from being exposed. At the same time, the windows can also be set to observe the inside.

[0046] Regarding the structure and shape of stoma ring 2, specifically:

[0047] The stoma ring 2 includes an outer ring 3 and an inner ring 4. The outer ring 3 and the inner ring 4 can be connected by threads or by a bayonet. Both the outer ring 3 and the inner ring 4 can be made of metal or plastic. The axes of the outer ring 3 and the inner ring 4 are aligned. The outer ring 3 is fitted onto the outer surface of the inner ring 4. A first groove is provided on the inner wall of the outer ring 3, and a second groove is provided on the outer wall of the inner ring 4. After the outer ring 3 and the inner ring 4 are connected, the first groove and the second groove are opposite each other and form a receiving space to accommodate the stoma bag 1. After the stoma bag 1 is used up, a new stoma bag 1 can be replaced by separating the outer ring 3 and the inner ring 4. The opening of the receiving space is located on the outer ring 3. On one side of ring 3 and inner ring 4, the internal width of the accommodating space is greater than the width of the opening. That is, the second groove on the inner ring 4 can be set as a plane, and the surface of the second groove is parallel to the surface of the inner ring 4. The first groove of the outer ring 3 can be set at an angle, and the diameter of the first groove decreases along the direction in which the stoma bag 1 is pulled out. The opening of the accommodating space can be set to allow only a single layer of stoma bag 1 to pass through, so as to avoid pulling out excess stoma bag 1. A ball bearing can also be set on the inner wall of the accommodating space. The ball bearing can make it easier to pull out the stoma bag 1. The inner ring 4 is connected to the patient's stoma. The inner ring 4 can be connected to the patient's stoma by adhesive.

[0048] Regarding the structure and shape of locking mechanism 5, specifically:

[0049] The locking mechanism 5 includes a first spring 7, a second spring 8, and a locking plate 6. The axis of the locking plate 6 coincides with the center of the outer ring 3. The locking plate 6 is disposed in the locking hole of the outer ring 3 and is slidably connected to the locking hole. The two sides of the locking plate 6 are respectively connected to the first spring 7 and the second spring 8. The first spring 7 and the second spring 8 are arranged at an angle. The bisector of the angle between the first spring 7 and the second spring 8 coincides with the axis of the locking plate 6. That is, the first spring 7 and the second spring 8 cause the locking plate 6 to have a tendency to move closer to the center of the outer ring 3, so that the locking plate 6 can press the stoma bag 1 in the accommodating space. When it is necessary to pull out the stoma bag 1, the locking plate 6 is pulled out in a direction away from the center of the outer ring 3. At this time, the first spring 7 and the second spring 8 are stretched, the locking plate 6 separates from the stoma bag 1, and the stoma bag 1 can be pulled out.

[0050] Optionally, two sets of locking plates 6, first springs 7 and second springs 8 are provided. The two sets of locking plates 6, first springs 7 and second springs 8 are arranged opposite each other along the diameter direction of the outer ring 3. Each set of locking plates 6, first springs 7 and second springs 8 is used to lock the stoma bag 1.

[0051] Regarding the structure and shape of cutting mechanism 9, specifically:

[0052] The cutting mechanism 9 includes a handle 12, a blade 10, and sealing blocks 11. The handle 12 can be rectangular, and there can be two handles 12, which are hinged at one end. The blade 10 and the two sealing blocks 11 are located on one handle 12 and face the other handle 12. When it is necessary to cut and seal the stoma bag 1, the two handles 12 are brought close to each other. Under the pressure of the two handles 12, the stoma bag 1 is cut into two sections by the blade 10, and the two sealing blocks 11 on both sides of the cut stoma bag 1 are sealed. Furthermore, the length of the blade 10 is greater than the width of the stacked stoma bag 1 so that the blade 10 can completely cut the stoma bag 1. The sealing blocks 11 on both sides of the blade 10 can be set as heating modules and connected to the battery inside the handle 12 to seal the stoma bag 1 by heat fusion.

[0053] Regarding the usage of the storage bag-type stoma bag device 1, the specifics are as follows:

[0054] In use, first attach the inner ring 4 to the patient's stoma, then place the stoma bag 1 onto the second groove of the inner ring 4, extending the beginning of the stoma bag 1 from the second groove. Then install the outer ring 3, pull out the locking plate 6, and pull the stoma bag 1 out to an appropriate length to accommodate excrement. Then loosen the locking plate 6 to fix the stoma bag 1. Further, when the stoma bag 1 needs to be replaced due to accumulated excrement, pull out the locking plate 6 and pull it outward by the length of the stoma bag 1. At this time, there are two stoma bag 1 lengths on the outside. The stoma bag 1 is cut and sealed by the blade 10 and sealing block 11 of the cutting mechanism 9, leaving the length of one stoma bag 1. This process does not expose the excrement and the patient's stoma, reduces odor, and avoids damage to the patient's skin and intestines.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
