Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically to an ostomy base. Background Technology

[0002] Ostomy bags are essential daily items for ostomy patients and need to be changed frequently. Therefore, patients need to attach an ostomy baseplate to the skin around the stoma to secure the ostomy bag. The convex ostomy baseplate, with its raised shape, can effectively conform to the depressions on the skin surface and smooth out surrounding skin folds, thereby improving sealing performance and preventing leakage of excrement.

[0003] However, most of these chassis still use a one-piece design with a fixed protrusion height, which makes it difficult to adapt to the significant differences in stoma shape and body surface indentation depth among different patients. This results in poor fit and limited range of adaptation, which not only affects the reliability of nursing care but also reduces the quality of life of patients.

[0004] Therefore, existing convex stoma chassis still have significant limitations in terms of structural adjustability and individual adaptability, and there is an urgent need for a new design that can flexibly adapt to different physiological structural characteristics. Utility Model Content

[0005] Purpose of the utility model: The technical problem to be solved by this utility model is to provide a stoma base plate that solves the problem that the protrusion degree of the existing stoma base plate cannot be adjusted.

[0006] Technical solution

[0007] To solve the above problems, the technical solution provided by this utility model is as follows:

[0008] An ostomy baseplate includes an upper adhesive layer, a lower adhesive layer, and a telescopic connector. The telescopic connector is connected between the upper adhesive layer and the lower adhesive layer. The telescopic connector is composed of an inner ring and an outer ring. The inner ring is sleeved inside the inner and outer rings. The outer ring is fixed to the upper adhesive layer, and the inner ring is fixed to the lower adhesive layer. The inner ring and the outer ring can move axially relative to each other.

[0009] Furthermore, both the upper adhesive layer and the lower adhesive layer have an opening at their center.

[0010] Furthermore, an annular buckle is fixedly provided on the upper surface of the adhesive layer.

[0011] Furthermore, the adhesive layer is provided with a liquid guiding sheet, which extends outward from the opening of the adhesive layer at an angle. One end of the liquid guiding sheet is connected to the opening of the adhesive layer, and the other end is located on the upper side of the annular buckle. The liquid guiding sheet is fixed to the adhesive layer only on the side close to the opening of the adhesive layer.

[0012] Furthermore, the liquid guiding sheet has a fan-shaped structure, and the liquid guiding sheet is provided with a liquid guiding port in cooperation with the opening of the upper adhesive layer.

[0013] Furthermore, the fan-shaped angle of the liquid guiding sheet is 10-50 degrees, and the two sides of the liquid guiding sheet are curved upwards.

[0014] Furthermore, the inner ring has a cavity, which is an inclined structure, and the cavity on the inner side of the inner ring gradually expands outward from the lower adhesive layer to the upper adhesive layer.

[0015] Furthermore, the outward expansion angle of the cavity in the inner ring is 0-20 degrees.

[0016] Furthermore, the outer surface of the outer ring gradually slopes outward from the lower adhesive layer to the upper adhesive layer.

[0017] Furthermore, the lower adhesive layer is folded upwards and adhered to the upper adhesive layer.

[0018] Beneficial effects

[0019] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0028] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] Combined with appendix Figure 1-3 An ostomy base plate includes an upper adhesive layer 1, a telescopic connector 2, and a lower adhesive layer 3. The telescopic connector 2 is disposed between the upper adhesive layer 1 and the lower adhesive layer 3. Both the upper adhesive layer 1 and the lower adhesive layer 3 are circular rings with an opening at their center.

[0031] An annular buckle 11 is fixedly provided on the upper surface of the adhesive layer 1. The annular buckle 11 is a buckle structure with the opening facing upward. The annular buckle 11 is used to engage with the ostomy bag. By fixing the ostomy bag, which is used in conjunction with the ostomy base plate, to the annular opening through the buckle engagement, the combination use of the ostomy base plate and the ostomy bag can be realized. The opening of the annular buckle 11 is provided with locking teeth.

[0032] The ostomy bag is equipped with a locking strip that engages with the locking teeth. By directly inserting the locking strip into the locking teeth, the ostomy bag is mounted on the annular buckle 11. Both the locking teeth of the annular buckle 11 and the locking strip on the ostomy bag are annular structures for easy fastening. The annular buckle 11 is preferably fixed to the adhesive layer 1 by heat welding.

[0033] The diameter of the opening of the top adhesive layer 1 is 5-15mm. A liquid guide plate 12 is fixedly provided at any position outside the opening of the top adhesive layer 1. The liquid guide plate 12 has a fan-shaped structure and is inclined. The narrower side of the liquid guide plate 12 is fixedly provided at the opening of the top adhesive layer 1. The end of the liquid guide plate 12 is aligned with the edge of the opening. The liquid flowing out of the opening of the top adhesive layer 1 can flow directly onto the liquid guide plate 12. The inclined structure of the liquid guide plate 12 makes the other side of the liquid guide plate 12 located above the annular buckle 11. The liquid guide plate 12 is fixed to the top adhesive layer 1 only at the narrower end. A liquid guide port is provided on the side of the liquid guide plate 12 that is aligned with the opening of the top adhesive layer 1. The liquid guide port can be formed by the combination of the liquid guide plate 12 and the opening of the top adhesive layer 1 to facilitate the flow of liquid. The liquid guide port facilitates the flow of liquid from the opening onto the liquid guide plate 12. The liquid guide port is preferably an inclined groove, through which liquid can flow.

[0034] The drainage strip 12 has slightly raised beveled sides to prevent liquid from scattering when flowing on it. The fan-shaped structure of the drainage strip 12 has an angle of 10-50 degrees. The drainage strip 12 not only facilitates liquid drainage, but also, after the ostomy bag is installed on the stoma base, its inclined structure supports the ostomy bag body, preventing it from becoming stuck together. The portion of the drainage strip 12 on the upper side of the adhesive layer 1 can be fixedly supported on the bottom surface by a bracket, ensuring the structural stability of the drainage strip 12.

[0035] The fluid guide 12 can undergo elastic deformation. When the annular buckle 11 needs to lock the ostomy bag, the fluid guide 12 is first bent to expose the annular buckle 11. After the ostomy bag is installed on the stoma base plate, the fluid guide 12 enters the ostomy bag and returns to its original shape, thereby playing the role of guiding and supporting the ostomy bag.

[0036] A telescopic connector 2 is provided between the upper adhesive layer 1 and the lower adhesive layer 3. The telescopic connector 2 consists of an inner ring 21 and an outer ring 22. The inner ring 21 of the telescopic connector 2 is fitted inside the outer ring 22 to form an integral structure. The inner ring 21 and the outer ring 22 of the telescopic connector 2 can move axially relative to each other, thereby extending or shortening the telescopic connector 2 by misalignment.

[0037] The relative movement of the inner ring 21 and the outer ring 22 can be achieved through an elastically deformable locking structure and friction fit. By setting an elastically deformable locking structure on the inner ring 21 and the outer ring 22, the inner ring 21 and the outer ring 22 can be fixed and moved relative to each other. At least one locking structure can be set on the side of the inner ring 21 and the outer ring 22 facing each other. The locking structure is composed of a wave structure or a bent structure that interlocks with each other. Through the elastic deformation of the interlocking position, the interlocking locking structures can move relative to each other, thereby realizing the relative movement of the inner ring 21 and the outer ring 22, thereby adjusting the distance between the upper adhesive layer 1 and the lower adhesive layer 3.

[0038] In other embodiments, the inner ring 21 and the outer ring 22 can be threaded together to extend and shorten the telescopic connector 2. By rotating either the inner ring 21 or the outer ring 22, the outer ring 22 can rotate relative to the inner ring 21 to rise or fall. The threaded engagement of the inner ring 21 and the outer ring 22 also needs to be combined with a friction engagement to give the inner ring 21 and the outer ring 22 a self-locking function.

[0039] The movement between the inner ring 21 and the outer ring 22 must have a self-locking function. Generally, a friction fit is used to achieve self-locking. When the external force is less than the friction force, the inner ring 21 and the outer ring 22 cannot move relative to each other. Only when the external force is greater than the friction force can the inner ring 21 and the outer ring 22 move relative to each other.

[0040] The inner ring 21 is fixed on the lower adhesive layer 3, and the outer ring 22 is fixed on the upper adhesive layer 1. The initial length of the extension connector composed of the inner ring 21 and the outer ring 22 is 2cm, and it can be extended to 6cm.

[0041] The inner ring 21 has a cavity inside. The cavity inside the inner ring 21 gradually expands outward from the lower adhesive layer 3 to the upper adhesive layer 1. The outward expansion angle of the cavity inside the inner ring 21 is 0-20 degrees. The outer surface of the outer ring 22 also has an outward expansion structure. The outer surface of the outer ring 22 gradually slopes outward from the lower adhesive layer 3 to the upper adhesive layer 1. The slope angle of the outer ring 22 is 0-20 degrees.

[0042] The cavity inside the inner ring 21 is used for the flow of liquid. The liquid flows out from the opening of the lower adhesive layer 3 through the cavity inside the inner ring 21 and then through the opening of the upper adhesive layer 1, thus entering the ostomy bag.

[0043] The opening of the lower adhesive layer 3 can be cut to fit the size of the user's stoma, and the opening of the upper adhesive layer 1 can also be cut to facilitate the flow of liquid into the stoma bag. At the same time, the upper adhesive layer 1 and the lower adhesive layer 3 are cut in such a way that at least three evenly distributed openings are cut at the opening, and the disassembled adhesive layer is folded over to be fixed to the inner ring 21.

[0044] The lower surface of the upper adhesive layer 1 is adhesive, and the lower adhesive layer 3 can be flipped upwards and adhered to the bottom surface of the upper adhesive layer 1. The inclined structure inside the inner ring 21 facilitates the cutting of the openings of the upper adhesive layer 1 and the lower adhesive layer 3, and the cut adhesive layer can be easily pasted onto the inner ring 21. The inclined structure on the outer surface of the outer ring 22 also facilitates the flipping upwards and adhering of the lower adhesive layer 3 onto the upper adhesive layer 1. The flipping of the lower adhesive layer 3 and its adherence to the upper adhesive layer 1 facilitates the adjustment of the positions of the inner ring 21 and the outer ring 22, which is used to maintain the length of the telescopic connector 2.

[0045] Preferably, the upper adhesive layer 1 has a diameter of 12-18cm, the annular buckle 11 has a diameter of 4-5cm, the liquid guiding sheet 12 extends 1-3cm beyond the upper adhesive layer; and the lower adhesive layer 3 has a diameter of 15-25cm.

[0046] When using it, cut about 3 openings in the lower adhesive layer 3 perpendicular to the direction of the reserved opening, according to the size of the incision. Then fold the adhesive inward to fit it into the inside of the telescopic plastic part. Repeat the same process for the upper adhesive layer 1, folding it inward to fit it into the telescopic plastic part as well. Then fold the lower adhesive plate upward to fully fit the lower adhesive plate with the upper adhesive plate. At this time, it is equivalent to a convex adhesive plate, which can be used for attachment.

[0047] The upper adhesive layer 1 has a backing film attached to it, and a release material is attached to the bottom of the upper adhesive layer 1 for bonding the lower adhesive layer 3. The lower adhesive layer 3 has a backing film attached to its upper part and a release material attached to its lower part for bonding to the skin during use. The material of the backing film is preferably PE or EMA.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
