Description

Technical Field

[0001] This invention relates to the field of medical auxiliary products technology, and in particular to a drainage tube fixing device. Background Technology

[0002] Drainage tubes are widely used in clinical medicine to address postoperative drainage needs. They are primarily placed in human tissue or specific body cavities to drain blood, tissue fluid, secretions, and other fluids, preventing their accumulation in specific areas and thus avoiding adverse symptoms such as compression or irritation of organs. They also prevent postoperative infection and impair wound healing, and facilitate postoperative observation of active bleeding at the surgical site or suture sites. Furthermore, monitoring changes in the properties, quantity, and composition of various drainage fluids helps monitor the patient's postoperative recovery. Since drainage tubes are usually left in place for a period of time, how they are secured significantly impacts user comfort.

[0003] The most traditional way to fix drainage tubes is to attach part of the drainage tube to the body with tape, so that the drainage tube inserted by the user is less likely to be accidentally pulled off. However, the stickiness of the tape can easily cause damage to the skin surface when the tape is removed, and fixing the drainage tube directly to the skin in contact can also easily cause pressure injury.

[0004] like Figures 18 to 20 The image shows a prior art drainage tube fixing device, comprising: a patch 91 with a tube hole 911 at its center and a cutout 912 extending to the tube hole 911 on one side of its periphery; an adhesive layer 913 on the bottom surface of the patch 91, on which a tearable release paper 914 is attached; and a fixing seat 92 disposed on the top surface of the patch 91 and close to or near the tube hole 911; the fixing seat 92 having a strap 921 and a strap hole 922 on the side facing the tube hole 911; the strap 921 having a plurality of anti-reverse teeth 923 arranged along its length; and the strap hole 922 having a plurality of latching teeth 924 that can engage and latch with the anti-reverse teeth 923.

[0005] In use, the release paper 914 is peeled off, and the drainage tube 93 is introduced into the tube hole 911 through the cut 912. The patch 91 is firmly adhered to the skin using the adhesive layer 913. The strap 921 is wrapped around the drainage tube 93 and then passed through the strap hole 922 of the fixing seat 92. The buckle teeth 924 in the strap hole 922 and the anti-reverse teeth 923 of the strap 921 engage with each other to form a one-way limiting locking form, so that the drainage tube 93 is bound and fixed towards the fixing seat 92 by the strap 921.

[0006] However, the existing drainage tube fixation device has a hole 911 at the center of the patch 91 for the drainage tube 93 to pass through, and a fixing seat 92 is located on the top surface of the patch 91 close to or against the hole 911. Due to the obstruction of the patch 91 and the fixing seat 92, medical personnel cannot clearly observe the wound, which makes wound disinfection and cleaning difficult. Furthermore, because the drainage tube 93 has various diameters, when the strap 921 binds and fixes the drainage tube 93 towards the fixing seat 92, it is easy to cause deformation or displacement of the drainage tube, thus affecting the drainage effect and wound healing. Therefore, designing a more user-friendly and effective drainage tube fixation device has become an important direction in current medical device research and development. Summary of the Invention

[0007] This invention provides a drainage tube fixing device, comprising: a fixing patch, the fixing patch being annular in shape, having a hollow portion at its center and a cut extending to the hollow portion on one side of its periphery, and an adhesive layer on the bottom surface of the fixing patch; a fixing base, disposed on the top surface of the fixing patch, the fixing base having a strap and a strap hole on the side facing the hollow portion, the strap having a plurality of anti-reverse teeth arranged along its length, at least one elastic buckle on at least one side of the strap hole, the elastic buckle having at least one locking tooth on the side facing the strap hole that can engage with the anti-reverse teeth, the upper side of the fixing base having a sliding groove, and a locking tooth portion protruding inward on each side of the sliding groove; and a... The support unit includes a slider with a sliding base at the bottom and an operating part at the top. One end of the slider has a top-positioning part, and the other end has two opposing elastic locking parts on both sides. The sliding base is slidably installed in the sliding groove. The elastic locking parts can be engaged with the locking teeth to form a positioning. By pushing the operating part, the slider can move forward towards the hollow part or backward away from the hollow part, thereby moving the top-positioning part accordingly. During the movement of the slider, the elastic locking parts can continuously bend inward and spring back outward. After movement, the elastic locking parts re-engage with the locking teeth to form a positioning.

[0008] The main purpose of the drainage tube fixing device of the present invention is that a hollow part is provided at the center of the fixing patch. When in use, the drainage tube is located at the center of the hollow part, which can effectively avoid obstructing the wound through which the drainage tube is inserted, so that medical staff can clearly observe the wound condition and facilitate the disinfection and cleaning of the wound.

[0009] Another objective of the drainage tube fixing device of the present invention is that, when in use, the drainage tube is first abutted and positioned by the sliding member, and then the drainage tube is secured and fastened towards the abutting and positioning part by the strap around the drainage tube. This design can effectively prevent the drainage tube from deforming or shifting, and ensure that the drainage effect and wound healing are not affected. Attached Figure Description

[0066] The following description, in conjunction with the drawings of preferred embodiments of the present invention, is intended to enable those skilled in the art to implement the invention based on the statements in this specification.

[0067] First, please refer to the following: Figures 1 to 4 As shown, the drainage tube fixing device of the present invention includes: a fixing sticker 10, a fixing base 20 and a supporting unit 30.

[0068] The fixing sticker 10 is ring-shaped with a hollow part 11 at the center and a cut 12 on one side of the periphery. The cut 12 extends to the hollow part 11. The bottom surface of the fixing sticker 10 is provided with an adhesive layer 13, and a tearable release paper 14 is attached to the adhesive layer 13. In this embodiment, the hollow part 11 is circular and the diameter of the hollow part 11 is 20 mm to 80 mm. The release paper 14 is composed of two symmetrical semi-circular release papers.

[0069] The fixing base 20 is disposed on the top surface of the fixing sticker 10. The fixing base 20 has a strap 21 and a through strap hole 22 on the side facing the hollow part 11. The strap 21 has a plurality of anti-reverse teeth 211 arranged along the longitudinal direction. At least one side of the strap hole 22 is provided with an elastic buckle 221. The elastic buckle 221 has at least one buckle tooth 222 on the side facing the strap hole 22 that can engage with the anti-reverse teeth 211. The upper side of the fixing base 20 is provided with a sliding groove 23. A locking tooth portion 231 is respectively protruding inward on both sides of the sliding groove 23. In this embodiment, an elastic buckle 221 is provided on one side of the strap hole 22, and a buckle tooth 222 is provided on the side of the elastic buckle 221 facing the strap hole 22.

[0070] The support unit 30 includes a slider 31. The bottom of the slider 31 is provided with a sliding base 311 and the top is provided with an operating part 312. One end of the slider 31 is provided with a top-positioning part 313, and the other end is provided with two opposing elastic locking parts 314. The sliding base 311 is slidably installed in the sliding groove 23. The elastic locking parts 314 can be locked into the locking teeth 231 to form a positioning. By pushing the operating part 312, the slider 31 can move forward towards the hollow part 11 or backward away from the hollow part, thereby moving the top-positioning part accordingly. During the movement of the slider 31, the elastic locking parts 314 can continuously bend inward and spring back outward. After the movement, the elastic locking parts 314 are re-locked into the locking teeth 231 to form a positioning. In this embodiment, the top-positioning part 313 is concave arc-shaped.

[0071] During use, first peel off the release paper 14, then introduce the drainage tube 40 into the center of the hollow part 11 through the incision 12. Next, use the adhesive layer 13 to firmly adhere the fixation patch 10 to the patient's skin, ensuring that the fixation patch 10 is fixed around the drainage tube 40 (e.g., Figure 5 (As shown), then by pushing the operating part 312, the sliding member 31 is driven forward toward the hollow part 11 until the abutting and positioning part 313 abuts against the drainage tube 40 (as shown). Figure 6 (As shown), the strap 21 is then wrapped around the drainage tube 40 and passed through the strap hole 22 of the fixing base 20, so that the buckle teeth 222 in the strap hole 22 and the anti-reverse teeth 211 of the strap 21 engage with each other to form a one-way limiting locking form, and the drainage tube 40 is fastened and secured by the strap 21 towards the fixing base 20 (as shown). Figure 7 As shown in the figure, the drainage tube 40 is fixed.

[0072] When removing the drainage tube fixing device of the present invention, the elastic buckle 221 is pulled outward to separate the buckle teeth 222 of the elastic buckle 221 from the anti-reverse teeth 211 of the strap 21 (e.g., Figure 8 (As shown), then the strap 21 is pulled out of the strap hole 22 to release the knot around the drainage tube 40. Then, by pushing the operating part 312, the sliding member 31 is driven backward away from the hollow part 11 until the abutting positioning part 313 separates from the drainage tube 40 (as shown). Figure 9 (As shown), finally peel the fixation patch 10 off the patient's skin (as shown). Figure 10 (As shown), the entire demolition process is completed.

[0073] In addition, such as Figures 11 to 17As shown, this is another embodiment of the drainage tube fixing device of the present invention. The difference between this other embodiment and the above embodiment is that the support unit 30 further includes a positioning member 32. The positioning member 32 is slidably disposed between the sliding base 311 and the operating part 312 of the sliding member 31, and can move between a release position 32A and a positioning position 32B. The positioning member 32 is provided with a positioning block 321. When the positioning member 32 is located at the release position 32A, the two elastic locking parts 314 are not blocked by the positioning block 321, so the two elastic locking parts 314 can be bent and deformed inward. When the positioning member 32 moves to the positioning position 32B, the positioning block 321 will be locked between the two elastic locking parts 314, restricting the two elastic locking parts 314 from bending and deforming inward.

[0074] Therefore, when the sliding member 31 is pushed forward towards the hollow portion 11 or backward away from the hollow portion by pushing the operating part 312, the positioning member 32 remains in the release position 32A. When the sliding member 31 moves forward towards the hollow portion 11, causing the abutting positioning part 313 to abut against the drainage tube 40, the positioning member 32 can be pushed to the positioning position 32B, so that the positioning block 321 is locked between the two elastic locking parts 314, thereby restricting the two elastic locking parts 314 from bending and deforming inward, thus making the sliding member 31 stably positioned and preventing the sliding member 31 from sliding unexpectedly.

[0075] The following beneficial effects can be obtained from the above specific embodiments:

[0076] 1. The drainage tube fixing device of the present invention has a hollow part 11 at the center of the fixing patch 10. When in use, the drainage tube 40 is located at the center of the hollow part 11, which can effectively avoid obstructing the wound through which the drainage tube 40 passes. During use, medical staff can clearly observe the condition of the wound, which is crucial for subsequent disinfection and cleaning. Good visibility can help medical staff to detect abnormalities in the wound in time, and then take corresponding treatment measures to reduce the risk of infection and improve patient safety.

[0077] 2. In the present invention, the drainage tube fixing device first uses the sliding member 31's abutting and positioning part 313 to abut the drainage tube 40, and then uses the strap 21 to wrap around the drainage tube 40, binding the drainage tube 40 towards the abutting and positioning part 313. The abutting and positioning part 313, together with the strap 21, secures the drainage tube 40. This design can effectively prevent the drainage tube 40 from deforming or shifting, ensuring that the drainage effect and wound healing are not affected.
