[0014] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.
[0015] In order to illustrate the technical scheme of the utility model, the following is described by specific embodiments.
[0016] As Figures 1-3 shown, the durable drainage tube fixing patch provided by the embodiment comprises a base layer patch 1 and a fixer 2, the top of the base layer patch 1 is provided with a center ring 3, the top of the center ring 3 is provided with a groove to form a ring of clamping hooks 31, the top of the clamping hooks 31 protrudes inward, the inner wall of the center ring 3 is further provided with a plurality of limiting strips 32, which are two limiting strips in the figure, the bottom of the fixer 2 is provided with a joint 4, the lower part of the joint 4 has a larger diameter than the upper part, wherein the lower part of the joint 4 is provided with a narrow opening 41 with a width larger than that of the limiting strips, the top of the fixer 1 is provided with a pair of arc-shaped grooves 11, and the side edge of the fixer 1 is further connected with a locking cover 5 through a rotating shaft.
[0017] The fixing patch of the structure is divided into two parts, which are the base layer patch and the fixer, the fixer is made of plastic material, the top of the fixer is provided with two arc-shaped grooves for placing the drainage tube, the top of the arc-shaped groove can also be provided with a clamping strip to preliminarily limit the drainage tube, and then the locking cover is closed to press the drainage tube. Since the structure adopts the way of fixing the drainage tube by the fixer, compared with the cross-sticking tape form, the fixing is more firm. Moreover, two drainage tubes can be fixed at the same time without using two fixing patches. In addition, by this way of fixing, when the drainage tube is replaced, the fixing patch also does not need to be replaced, the locking cover is opened, the drainage tube is directly taken out and replaced, and the existing fixing patch needs to be torn off the adhesive tape, the adhesive tape after being torn off has lower adhesion and cannot be used continuously. Therefore, the durability of the product is also stronger.
[0018] The joint at the bottom of the fixer is directly inserted into the center ring on the base layer patch, the top of the center ring is provided with a ring of clamping hooks, and the bottom of the joint is provided with a peripheral inverted edge. When the joint is inserted, the clamping hooks are first opened, and after being inserted in place, the clamping hooks automatically recover to limit the lower part of the joint. Since the lower part of the joint is provided with a narrow opening, after the joint is inserted, the limiting strips in the center ring are located in the narrow opening of the joint, and under the limiting of the narrow opening, the fixer can only rotate slightly. When the fixing patch is pasted on the active part of the human body, the fixer can rotate slightly, can adapt to such changes in activity, can minimize the degree of pulling of the drainage tube on the fixing patch, and the fixing patch will not fall off, which is more durable.
[0019] Further, the top of the fixer 1 is further provided with a pair of shallow grooves 12, the locking cover 5 is of a door type structure, the other side edge of the fixer 1 is located between the pair of shallow grooves and outwardly formed with a protruding strip 13, and the inner side of the locking cover 5 is formed with a clamping groove 51 corresponding to the position of the protruding strip. After the locking cover is buckled, the locking cover is located in the shallow groove to press the drainage tube. And the protruding strip 13 is buckled into the clamping groove 51 of the locking cover. Since the fixer is made of plastic material and can have a small deformation, after the locking cover is buckled, the locking cover can also be relatively conveniently opened.
[0020] In addition, in order to further prolong the use time of the fixing patch, the bottom of the base layer patch 1 is pasted with a hand-tearable adhesive film 6. The bottom surfaces of the base layer patch and the hand-tearable adhesive film are both adhesive layers, and the top surface of the hand-tearable adhesive film is smooth. In initial use, the hand-tearable adhesive film is not torn off, and the base layer patch is pasted on the skin through the hand-tearable adhesive film. After use for a period of time, if the adhesion of the hand-tearable adhesive film is not strong, the hand-tearable adhesive film can be torn off, and the bottom surface of the base layer patch is directly pasted on the skin, the pasting effect is the same as that of a new fixing patch, and the durability of the product can be improved through this way.
[0021] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
