Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to an elastic bionic suction cup fixation patch. Background Technology

[0002] A gastrostomy tube is a medical device primarily used for patients who are unable to eat normally through the mouth. It is surgically inserted directly into the stomach, allowing nutrients to be delivered directly to the stomach to meet the patient's nutritional needs. This treatment is commonly used for patients with dysphagia, esophageal obstruction, or other conditions that impair normal eating.

[0003] In order to prevent the gastrostomy tube from swaying or falling off during use, a fixing tape is usually used to attach the tube to the patient's abdomen using the adhesive backing of the fixing tape.

[0004] However, in actual use, the chemical adhesive on traditional fixation tape is in prolonged contact with the patient's skin, which can easily cause allergies and damage to the patient's skin, thereby increasing the patient's pain. Therefore, in order to solve the above-mentioned problems, an elastic bionic suction cup fixation patch is provided. Utility Model Content

[0005] The purpose of this invention is to solve the problem that traditional adhesive tapes can easily cause skin allergies and damage, thus increasing patient suffering. This invention proposes an elastic bionic suction cup fixation patch.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An elastic biomimetic suction cup fixing patch includes a substrate and further includes: a plurality of suction nozzles arranged in an array on the substrate, wherein each suction nozzle has a plurality of through grooves arranged in a ring at the opening of the suction nozzle, making the opening of the suction nozzle wavy; the substrate is provided with a fixing member for limiting the fistula; a plurality of ribs are fixedly connected in a ring at equal intervals to the outer wall of the suction nozzle, wherein the ribs are located between two adjacent through grooves; the substrate is provided with a locking member for positioning them.

[0008] In order to confine the fistula to the substrate, preferably, the fixing member includes an anti-slip ring, and the substrate has a central hole through which the anti-slip ring is fixedly connected.

[0009] To further improve the friction of the inner wall of the anti-slip ring, the anti-slip ring is provided with multiple protrusions, and the multiple protrusions are fixedly connected in a ring at equal intervals on the inner wall of the anti-slip ring.

[0010] To enable the substrate fixation patch to be mechanically fixed to the patient's abdomen, preferably, the locking component includes a flexible strip. The substrate has mounting holes on both sides, and the flexible strip is inserted into the mounting holes. One end of the flexible strip is fixedly connected to a buckle, and the outer side of the flexible strip is fixedly connected to a locking tooth that engages with the buckle.

[0011] To improve the friction of the inner wall of the flexible strip and enhance patient comfort, the flexible strip is further provided with protective particles, which are fixedly connected to the inner side of the flexible strip.

[0012] To facilitate inserting one end of the flexible strip into the buckle, a guide head is fixedly connected to the end of the flexible strip away from the buckle, and the guide head is triangular in shape.

[0013] To ensure the suction effect of the nozzles, preferably, the number of nozzles is 4 to 8.

[0014] To maximize the fixing surface area of ​​the fixing sticker, the substrate is preferably elliptical in shape.

[0015] To make the fixation patch more flexible, preferably, the substrate is made of medical-grade silicone and has a thickness of 2mm-5mm.

[0016] To make the flexible strip lighter, the material of the flexible strip is nylon.

[0017] Compared with the prior art, this utility model provides an elastic bionic suction cup fixing sticker, which has the following beneficial effects:

[0018] 1. This elastic bionic suction cup fixation patch, through the combined use of a base plate, suction nozzle, and anti-slip ring, can mimic the shape of an octopus suction cup to support and fix the fistula outside the patient's body, thereby replacing traditional adhesive tape and chemical bonding, avoiding skin allergies and damage, and thus avoiding increasing the patient's pain.

[0019] 2. This elastic bionic suction cup fixation patch, through the design of through grooves and ribs, enables the opening of the suction nozzle to form a wave shape. The wave-shaped sealing opening helps the suction nozzle to adjust its shape more flexibly to match the contour of non-planar objects, thereby adapting to the patient's skin texture, preventing air leakage from the suction nozzle, and thus improving the effectiveness of the fixation patch.

[0020] 3. This elastic bionic suction cup fixation patch, through the combination of soft strips, buckles and teeth, can fix the base plate to the patient's abdomen through active fixation, and in conjunction with the passive fixation of the suction nozzle, it further improves the fixation effect of the patch on the fistula.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Example:

[0031] Reference Figures 1-5This utility model embodiment provides an elastic bionic suction cup fixation patch, including a substrate 1. The substrate 1 is made of medical-grade silicone and has a thickness of 2mm-5mm, preferably 3mm in this fixation patch, making the substrate 1 more flexible and malleable, ensuring that the substrate 1 can better adhere to the patient's skin. The substrate 1 is elliptical in shape, but can also be circular, allowing for a larger fixing surface area, better stability, and rounded ends to prevent scratching the patient. It also includes: multiple suction nozzles 2, arranged in an array on the substrate 1. The quantity is 4-8, preferably 6 in this fixing patch, which can ensure that multiple suction nozzles 2 have sufficient adsorption force and ensure the stability of the fixing patch. The suction nozzle 2 is provided with multiple through grooves 21, which are arranged in a ring at the opening of the suction nozzle 2, so that the opening of the suction nozzle 2 forms a wave shape. The base plate 1 is provided with a fixing member for limiting the fistula. Multiple ribs 22 are fixedly connected to the outer wall of the suction nozzle 2 in a ring at equal intervals. The ribs 22 are located between two adjacent through grooves 21. The base plate 1 is provided with a locking member for positioning them.

[0032] Specifically, in use, the base plate 1, suction nozzle 2, and fixing components work together to mimic the shape of an octopus suction cup to support and fix the fistula outside the patient's body, thus replacing traditional adhesive tape and avoiding skin allergies and damage that could increase the patient's pain. The through groove 21 and ribs 22 allow the opening of the suction nozzle 2 to form a wave shape. This wave-shaped sealing opening helps the suction nozzle 2 to adjust its shape more flexibly to match the contours of non-planar objects, thereby adapting to the patient's skin texture and preventing air leakage from the suction nozzle 2, thus improving the effectiveness of the fixing patch. The locking component allows the base plate 1 to be actively fixed to the patient's abdomen, and combined with the passive fixation of the suction nozzle 2, further improves the fixing effect of the patch on the fistula.

[0033] The fastener in this fastener includes an anti-slip ring 3 made of rubber. A central hole 4 is provided through the substrate 1, and the anti-slip ring 3 is fixedly connected in the central hole 4. The anti-slip ring 3 is provided with multiple protrusions 5, and the multiple protrusions 5 are fixedly connected in a ring at equal intervals on the inner wall of the anti-slip ring 3. The number of protrusions 5 is 8 to 15, and the number of protrusions 5 in this fastener is preferably 13.

[0034] Specifically, by setting the central hole 4 and the anti-slip ring 3, the fistula can be passed through the anti-slip ring 3 during use, which can limit the fistula on the base plate 1, thereby improving the stability of the fistula. Furthermore, by setting the protrusion 5, the friction of the inner wall of the anti-slip ring 3 can be increased, thereby improving the limiting effect on the fistula.

[0035] The locking component in the fixing clip includes a flexible strip 6. Mounting holes 7 are provided on both sides of the base plate 1. The flexible strip 6 is inserted into the mounting holes 7. One end of the flexible strip 6 is fixedly connected to a buckle 61, and the outer side of the flexible strip 6 is fixedly connected to a tooth 62 that engages with the buckle 61. The flexible strip 6 is made of nylon, making it lighter.

[0036] Specifically, through the cooperation of the soft strip 6, the mounting hole 7, the buckle 61 and the locking teeth 62, when in use, by passing the soft strip 6 through the mounting hole 7, then wrapping one end of the soft strip 6 around the patient's body and inserting it into the buckle 61, so that the locking teeth 62 are engaged in the buckle 61, the base plate 1 can be fixed to the patient's abdomen in an active fixation manner, which further improves the fixation effect of the fixation patch on the fistula.

[0037] The aforementioned soft strip 6 is provided with protective particles 8, which are made of medical-grade silicone and are fixedly connected to the inner side of the soft strip 6.

[0038] Specifically, by setting up the protective particles 8, the friction of the inner wall of the soft strip 6 can be increased and the patient's comfort can be improved.

[0039] The end of the aforementioned flexible strip 6 away from the buckle 61 is fixedly connected to a guide head 63, and the guide head 63 is triangular in shape.

[0040] Specifically, the guide head 63 can guide one end of the soft strip 6, making it easier to quickly insert one end of the soft strip 6 into the buckle 61.

[0041] Working principle: During use, this elastic bionic suction cup fixation patch first allows the fistula outside the patient's body to pass through the anti-slip ring 3, which can initially limit the fistula. Then, by pressing the base plate 1, the suction nozzle 2 is negatively attached to the patient's skin. Through the combined use of the base plate 1, suction nozzle 2, and anti-slip ring 3, it can mimic the shape of an octopus suction cup to support and fix the fistula outside the patient's body, thereby replacing the traditional chemical adhesive tape and avoiding skin allergies and damage, thus avoiding increasing the patient's pain.

[0042] Furthermore, the through groove 21 and rib 22 enable the opening of the suction nozzle 2 to form a wave shape. The wave-shaped sealing opening helps the suction nozzle 2 to adjust its shape more flexibly to match the contour of non-planar objects, thereby adapting to the patient's skin texture and preventing air leakage from the suction nozzle 2, thus improving the effectiveness of the fixation patch.

[0043] In addition, after the substrate 1 is adsorbed and fixed, by passing the soft strip 6 through the mounting hole 7, wrapping one end of the soft strip 6 around the patient's body and inserting it into the buckle 61, the locking teeth 62 are locked in the buckle 61, and the substrate 1 can be fixed to the patient's abdomen by active fixation. Combined with the passive fixation of the suction nozzle 2, the fixation effect of the fixation patch on the fistula is further improved.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
