Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a permanently implantable ostomy chassis and an ostomy bag kit. Background Art

[0002] A stoma is caused by diseases of the digestive system or urinary system and requires surgical treatment to separate the intestine and lead one end of the intestine to the body surface (the anus or urethra is moved to the abdominal wall) to form an opening, usually in the abdomen. It can achieve intestinal decompression, reduce obstruction, and protect the anastomosis or damage of the distal intestine. After a radical cystectomy for urinary bladder cancer, a section of the intestine needs to be taken for stoma to collect and drain urine, promote the recovery of intestinal and urinary tract diseases, and even save the patient's life.

[0003] For patients with a stoma, such as an ileostomy, it is usually necessary to provide a stoma bag at the stoma to collect human excrement. In the prior art, a commonly used stoma bag is a two-piece stoma bag, which usually includes a chassis and a bag body, wherein the chassis is provided with adhesive, and the bag body is detachably connected to the chassis, and the bag body is used to store excrement, such as urine, feces, etc. In actual use, the chassis is fixed to the skin around the stoma by the adhesive, and then the bag body is installed on the chassis. However, the existing two-piece ostomy bags usually still have some problems. 1. The cost of use is relatively high, because the chassis usually needs to be replaced every 3 to 5 days, and no longer than 7 days, and when the inner chassis leaks, it needs to be replaced immediately. The cost of each chassis is relatively high. Frequent replacement greatly increases the cost and the burden on patients; 2. It is easy to leak. Since the chassis is fixed to the patient's skin with glue, the connection is not reliable, especially in the summer when it is easy to sweat, it is very easy to fall off; 3. Replacement is inconvenient. When installing the existing chassis, it needs to be aligned with the fistula opening. It is usually inconvenient for patients to replace it by themselves, and they need the assistance of medical staff or family members, which is very inconvenient; 4. The chassis of the ostomy bag is fixed by gluing, which is easy to cause complications such as skin inflammation and redness. Summary of the invention

[0004] The purpose of the present invention is to improve the deficiencies in the prior art and to provide an ostomy base plate which is simple in structure, compact and easy to use and can be permanently implanted in the patient's body and cooperate with a bag body arranged outside the body. It not only has low cost and will not cause leakage and other problems, but also is convenient for the patient to replace the bag body by himself without any complications.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] The first aspect of the present invention aims to solve the problems of frequent replacement of ostomy base plates, high cost, easy leakage, and inability to be replaced by individuals, and provides a permanently implantable ostomy base plate, including an implantation part for implantation in the body and an extracorporeal part connected to the implantation part, the extracorporeal part is used to remain outside the body, the extracorporeal part is used to surround the ostomy opening along the circumferential direction of the ostomy opening, and the extracorporeal part is constructed with a first connecting part for detachably connecting to a bag body. In the present solution, the implanted part of the ostomy chassis can be implanted into the patient's body during the ostomy operation, usually implanted into the patient's skin, and the external part can just surround the ostomy opening along the circumferential direction of the ostomy opening, so that the excrement flowing out of the ostomy opening can be constrained within the external part to avoid leakage, and the external part extends outside the body and can be permanently left outside the patient's body. The external part is also provided with a first connecting part to cooperate with the second connecting part on the bag body to achieve a detachable connection, which not only allows the ostomy opening to be connected with the bag body outside the body, but also facilitates the replacement of the bag body; using the ostomy chassis provided by the present solution, there is no need to replace the chassis during the entire use process, only the bag body that matches it needs to be replaced regularly, which can not only greatly reduce costs and reduce the burden on patients, but also facilitate replacement, and the patient can easily complete the bag body replacement work by himself without the assistance of others, which is very convenient; in addition, since the ostomy chassis is arranged on the patient's abdominal wall in an implanted manner and does not involve glue, there are no problems such as unreliable connection, easy leakage, and easy to cause skin diseases, thereby effectively solving the shortcomings of the prior art.

[0007] In order to prevent the implant part implanted in the patient's body from falling off, preferably, the implant part includes a connecting tube and a connecting piece arranged on the outside of the connecting tube, one end of the connecting tube is connected to the external part, the connecting tube is used to be implanted in the body and surround the fistula opening inside, and the connecting piece is used to be implanted in the body and provide the connecting tube with a constraint along the central axis direction of the connecting tube. That is, in this scheme, after the implant part is implanted in the body, the connecting tube just surrounds the fistula opening, and the connecting piece can be in the subcutaneous muscle tissue outside the connecting tube and be constrained by the muscle tissue, thereby providing the connecting tube with a constraint along the central axis direction of the connecting tube, thereby effectively preventing the connecting tube from falling out along its own axis direction.

[0008] Preferably, the connecting piece is perpendicular to the central axis of the connecting tube, which is more convenient for positioning and fixing the implanted part during the fistula operation.

[0009] Preferably, the connecting tube is provided with a connecting piece of annular structure in the circumferential direction, or with a plurality of connecting pieces which are independent of each other, so as to facilitate the production and molding of the implant part, and to facilitate the convenient arrangement of the connecting piece when the implant part is implanted, so as to clamp the connecting piece in the subcutaneous muscle tissue around the stoma, thereby fixing the entire implant part.

[0010] In order to ensure that the implanted part can be safely implanted in the body, preferably, the connecting tube and the connecting piece are respectively made of polyester patch, polypropylene patch or expanded polytetrafluoroethylene patch. The polyester patch, polypropylene patch and expanded polytetrafluoroethylene patch are all materials that can be used for implantation in the body in the prior art. After being used to make the connecting tube and the connecting piece, they can be safely implanted in the body without complications.

[0011] The second aspect of the present invention is to solve the problem of the implant part and the human body muscle tissue being more compatible. Further, the connecting tube and / or the connecting sheet are respectively provided with a plurality of through holes.

[0012] Alternatively, the connecting tube and / or the connecting piece are mesh structures. By providing a plurality of through holes, when the connecting tube and the connecting piece are implanted in the body, the muscle tissues on both sides of the connecting tube and the connecting piece can extend from one side to the other side through the through holes during the growth and healing process, so that the connecting tube and the connecting piece can be firmly clamped in the muscle tissue, and the implanted part and the human muscle tissue are more compatible, which is conducive to making the connecting tube and the connecting piece implanted in the body more secure.

[0013] Preferably, the through hole is a combination of one or more of a square hole, a round hole, a strip hole, a triangular hole, and an elliptical hole.

[0014] In order to better surround the stoma and prevent leakage, preferably, the external part is a cylindrical structure, so as to match the shape of the connecting tube, so that when the stoma chassis is implanted, the stoma can be covered inside the stoma chassis, and when the stoma chassis is connected to the bag body, the stoma can be connected with the bag body and the leakage of excrement can be prevented.

[0015] Preferably, one end of the extracorporeal part is inserted into one end of the connecting tube, thereby realizing the connection between the extracorporeal part and the connecting tube. With such a connection method, on the one hand, the connecting tube can wrap around one end of the extracorporeal part, so that when the implanted part is implanted into the body, one end of the extracorporeal part can extend into the body for a certain distance under the wrapping of the connecting tube, thereby effectively preventing excrement from leaking out from the position where the extracorporeal part is connected to the connecting tube.

[0016] Preferably, the first connection part is an external thread, an internal thread, a buckle or a notch etc. provided on the external part, so as to match with the second connection part provided on the bag body, thereby realizing a detachable connection, so as to facilitate the replacement of the bag body.

[0017] An ostomy bag kit includes a bag body and an ostomy chassis, wherein the bag body is provided with an internal cavity for accommodating excreta, and the bag body is provided with a second connection part adapted to the first connection part, and the bag body and the external part are detachably connected through the cooperation of the second connection part and the first connection part. Through the cooperation of the bag body and the ostomy chassis, the ostomy opening can be effectively closed, and the excreta at the ostomy opening can be conveniently collected, the use cost is low, and there is no leakage problem, and by setting the cooperation of the first connection part and the second connection part, not only the installation and replacement of the bag body is convenient, but also the patient can perform the replacement operation by himself, which is very simple.

[0018] Compared with the prior art, the present invention provides a permanently implantable ostomy base and ostomy bag kit. The ostomy base can be permanently implanted in the patient's body and collect human excrement by cooperating with the bag body. During the entire use process, there is no need to replace the base, and only the bag body that matches it needs to be replaced regularly. This can not only greatly reduce costs and alleviate the patient's economic burden, but also facilitate replacement. The patient can easily complete the replacement of the bag body by himself without the assistance of others, which is very convenient. In addition, since the ostomy base is implanted in the patient's abdominal wall and does not involve glue, there are no problems such as unreliable connection, easy leakage, and easy to cause skin diseases. This can not only effectively solve the shortcomings of the prior art, but also has outstanding substantial characteristics and significant progress compared to the existing two-piece ostomy bags.

[0031] Fistula 200 , skin 201 , and muscle tissue 202 . DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0033] Example 1

[0034] See also Figure 1 , Figure 2 , Figure 6 and Figure 7 In this embodiment, a permanently implantable ostomy base plate is provided, including an implantation part 101 for implantation in the body and an external part 104 connected to the implantation part 101, the external part 104 is used to remain outside the body for connection with a bag body, the external part 104 is used to surround the ostomy opening 200 along the circumferential direction of the ostomy opening 200 to prevent leakage of excrement, and the external part 104 is constructed with a first connection part 105 for detachably connecting to the bag body to facilitate replacement of the bag body.

[0035] In this embodiment, the implant portion 101 in the ostomy chassis can be implanted into the patient's body during the ostomy surgery, usually implanted into the patient's skin 201 (not described in detail below), and the external portion 104 can just surround the ostomy opening 200 along the circumferential direction of the ostomy opening 200, so that the excrement flowing out of the ostomy opening 200 can be confined within the external portion 104 to avoid leakage, and the external portion 104 extends out of the body and can be permanently left outside the patient's body, such as Figure 1 , Figure 6 and Figure 7 As shown, the external part 104 is also provided with a first connecting portion 105 to cooperate with the second connecting portion on the bag body to achieve a detachable connection, which not only allows the fistula opening 200 to be connected to the bag body outside the body, but also facilitates the replacement of the bag body.

[0036] During the entire use of the ostomy base, it is only necessary to regularly replace the bag body that matches it, which can not only greatly reduce costs and alleviate the burden on patients, but also facilitate replacement. The patient can easily complete the replacement of the bag body by himself without the assistance of others, which is very convenient. In addition, since the ostomy base is implanted in the patient's abdominal wall and does not involve glue, there are no problems such as unreliable connection, easy leakage, and easy to cause skin 201 diseases, thereby effectively solving the shortcomings of the existing technology.

[0037] The implant part 101 has multiple embodiments. To prevent the implant part 101 implanted in the patient's body from falling off, preferably, the implant part 101 includes a connecting tube 102 and a connecting piece 103 arranged on the outside of the connecting tube 102. One end of the connecting tube 102 is connected to the external part 104. The connecting tube 102 is used to be implanted in the body and surround the fistula 200 inside. The connecting piece 103 is used to be implanted in the body and provide a constraint for the connecting tube 102 along the central axis direction of the connecting tube 102. Figure 1 , Figure 6 and Figure 7 As shown; in this solution, after the implant part 101 is implanted into the body, the connecting tube 102 just surrounds the fistula opening 200, and the connecting piece 103 can be stuck in the subcutaneous muscle tissue 202 outside the connecting tube 102 and be constrained by the muscle tissue 202, so as to provide constraints for the connecting tube 102 along the central axis direction of the connecting tube 102, thereby effectively preventing the connecting tube 102 from falling out along its own axis direction.

[0038] It can be understood that the connecting piece 103 and the connecting tube 102 have a variety of relative positional relationships. Preferably, the connecting piece 103 is perpendicular to the central axis of the connecting tube 102. Figure 1 and Figure 2As shown, it is more convenient to position and fix the implant part 101 during the fistula operation.

[0039] The structure and number of the connecting piece 103 can be determined according to actual needs. As a preferred embodiment, a connecting piece 103 with an annular structure is arranged in the circumferential direction of the connecting cylinder 102. Figure 1 and Figure 2 As shown, it is convenient to produce and shape the implant part 101, and it is convenient to set the connecting piece 103 when implanting the implant part 101, so that the connecting piece 103 can be stuck in the subcutaneous muscle tissue 202 around the fistula opening 200 to fix the entire implant part 101. In another preferred embodiment, the circumferential direction of the connecting tube 102 is provided with multiple independent connecting pieces 103 (that is, the number of connecting pieces 103 is greater than or equal to 2). As an example, Figure 3 As shown, three independent connecting pieces 103 are arranged in the circumferential direction of the connecting tube 102, and the three connecting pieces 103 are evenly distributed along the circumferential direction of the connecting tube 102; as another example, Figure 4 As shown, four independent connecting sheets 103 are arranged in the circumferential direction of the connecting tube 102, and the four connecting sheets 103 are evenly distributed along the circumferential direction of the connecting tube 102, ..., and can achieve the same technical effect, which will not be repeated here.

[0040] It can be understood that the connecting piece 103 can be arranged at the end of the connecting tube 102, or at the middle position of the connecting tube 102, and when multiple connecting pieces 103 are included, each connecting piece 103 can be arranged in the same plane, or respectively in different planes, and examples will not be given one by one here.

[0041] like Figure 1 As shown, the connecting tube 102 may preferably be a round tube, or may be a square tube, a conical tube or the like.

[0042] In order to ensure that the implant part 101 can be safely implanted in the body, preferably, in the present embodiment, the connecting tube 102 and the connecting piece 103 can be made of existing implantable materials respectively, for example, they can be made of polyester patch, polypropylene patch or expanded polytetrafluoroethylene patch respectively; the polyester patch, polypropylene patch and expanded polytetrafluoroethylene patch are all materials that can be used for implantation in the body in the prior art, and after being used to make the connecting tube 102 and the connecting piece 103, they can be safely implanted in the body without any complications.

[0043] like Figure 1 and Figure 2 As shown, in this embodiment, the external part 104 is also a cylindrical structure, so as to match the shape of the connecting tube 102. Figure 6 and Figure 7 As shown, when the ostomy base is implanted, the ostomy opening 200 can be covered inside the ostomy base, and when the ostomy base is connected to the bag body, the connection between the ostomy opening 200 and the bag body can be ensured, and leakage of excrement can be avoided.

[0044] In this embodiment, the material of the extracorporeal part 104 may be different from that of the implanted part 101. Preferably, the extracorporeal part 104 may be made of materials such as plastic, polymer material, carbon fiber, etc.

[0045] To prevent excrement from leaking out from the position where the external part 104 is connected to the connecting tube 102, in a more perfect solution, one end of the external part 104 is inserted into one end of the connecting tube 102, and the insertion depth can be determined according to actual needs, such as Figure 5 As shown, by adopting such a connection method, on the one hand, the connecting tube 102 can wrap one end of the external part 104, so that when the implant part 101 is implanted into the body, one end of the external part 104 can extend into the body (extend to the subcutaneous tissue) for a distance under the wrapping of the connecting tube 102, thereby effectively preventing excrement from leaking out from the position where the external part 104 and the connecting tube 102 are connected; on the other hand, by adopting the connecting tube 102 to wrap the external part 104, the external part 104 can be effectively isolated, thereby preventing the external part 104 from directly contacting the muscle tissue 202 of the human body, avoiding complications.

[0046] To achieve a detachable connection, the first connection portion 105 can adopt the connection structure of the chassis in the existing two-piece ostomy bag. Preferably, the first connection portion 105 is an external thread, an internal thread, a buckle or a notch, etc., arranged on the external part 104, so as to be compatible with the second connection portion arranged on the bag body, thereby achieving a detachable connection for replacement of the bag body. For example, in this embodiment, the first connection portion 105 is an external thread arranged on the external part 104, such as Figure 1 , Figure 6 and Figure 7 As shown, the structure is simple and easy to form.

[0047] Example 2

[0048] In order to make the implant part 101 and the human muscle tissue 202 more compatible, the main difference between the present embodiment 2 and the above-mentioned embodiment 1 is that in the fistula base provided in the present embodiment, the connecting tube 102 and / or the connecting sheet 103 are respectively provided with a plurality of through holes 106, such as Figure 8As shown, by setting a plurality of through holes 106, when the connecting tube 102 and the connecting piece 103 are implanted in the body, the muscle tissue 202 on both sides of the connecting tube 102 and the connecting piece 103 can extend from one side to the other side through the through holes 106 during the process of growth and healing, so that the connecting tube 102 and the connecting piece 103 can be firmly clamped in the muscle tissue 202, and the implanted part 101 and the human muscle tissue 202 are more compatible, which is conducive to the connecting tube 102 and the connecting piece 103 implanted in the body to be more secure.

[0049] It can be understood that the shape of the through hole 106 can be determined according to actual needs. As a priority, the through hole 106 can be a combination of one or more of a square hole, a round hole, a strip hole, a triangular hole, and an elliptical hole; and the size and density of the through hole 106 can also be determined according to actual needs. When the density of the through hole 106 is large, the connecting tube 102 and / or the connecting sheet 103 can respectively form a mesh structure, that is, the connecting tube 102 and / or the connecting sheet 103 can also be a mesh structure, in which the through hole can also become a sieve hole, such as Fig. 9 As shown, no further description is given here.

[0051] This embodiment provides an ostomy bag kit, comprising a bag body and the ostomy base plate described in Embodiment 1 or Embodiment 2, wherein the bag body is provided with an internal cavity for accommodating excreta, and the bag body is further provided with a second connection portion adapted to the first connection portion 105, and the bag body is detachably connected to the external part 104 through the cooperation of the second connection portion and the first connection portion 105. When the bag body is arranged on the ostomy base plate, the internal cavity is connected to the ostomy opening 200, and the cooperation of the bag body and the ostomy base plate can effectively close the ostomy opening 200, and the excreta at the ostomy opening 200 can be conveniently collected, with low use cost and no leakage problems, and the cooperation of the first connection portion 105 and the second connection portion not only facilitates the installation and replacement of the bag body, but also facilitates the patient to perform the replacement operation by himself, which is very simple.

[0052] In this embodiment, the bag body may be a bag body commonly used in the prior art.

[0053] It can be understood that when the first connecting part 105 is an external thread, the second connecting part is an internal thread that matches the external thread, when the first connecting part 105 is an internal thread, the second connecting part is an external thread that matches the internal thread, when the first connecting part 105 is a snap, the second connecting part is a notch that matches the snap, and when the first connecting part 105 is a notch, the second connecting part is a notch that matches the notch.

[0054] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
