Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a device for fixing a gastrostomy tube, particularly a fixing device that integrates a Y-shaped feeding head storage function. Background Technology

[0002] Gastrostomy is an important way to provide enteral nutritional support for patients who are unable to eat orally for a long time. Proper fixation of the gastrostomy tube is crucial post-operatively. Traditional fixation methods, such as using gauze, adhesive tape, or bandages, suffer from problems such as insecure fixation, easy displacement, easy contamination, and inconvenient care. While some existing gastrostomy tube fixation straps have improved upon these methods, they still have the following shortcomings: 1) The fixation angle of the gastrostomy tube is not adjustable, making the tube prone to twisting or compression when the patient's position changes; 2) Adjusting the tightness of the fixation strap is inconvenient, affecting patient comfort; 3) There is a lack of effective protection and storage for the gastrostomy tube and external connectors (such as Y-shaped feeding heads). The Y-shaped feeding heads are exposed, easily contaminated with dust and bacteria, and are prone to shaking and pulling when not in use, posing safety hazards and contamination risks.

[0003] Therefore, it is necessary to provide a more comprehensive, convenient, and safer gastrostomy tube fixation device. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and to propose a gastrostomy tube fixation device with integrated Y-shaped feeding head storage, comprising: The main body of the fixation strap has a catheter hole in the middle for the gastrostomy tube to pass through; The anti-dislodgement fixation structure is located in the middle of the fixation strap body and close to the catheter hole. It is used to clamp and fix the gastrostomy tube that passes through the catheter hole, and its fixation angle can be adjusted. Quick-adjusting buckles are located at both ends of the main body of the fixation strap, and are used to quickly adjust the tightness of the fixation strap when worn on the patient. A detachable protective cover is installed outside the anti-detachment fixing structure and conduit holes to provide physical protection and isolation. A dustproof storage bag, located on the main body of the fixing strap and on one side of the anti-fouling protective cover, is used to store the Y-shaped feeding head of the gastrostomy tube; The anti-detachment fixing structure includes: The toothed disc is rotatably connected to the main body of the fixed belt; An arc-shaped fixing clamp, which rotates around an axis and is mounted on a toothed disc, is used to hold the gastrostomy tube. The telescopic locking mechanism, installed on the main body of the fixed belt, is used to lock the rotational position of the toothed disc, thereby fixing the angle of the arc-shaped fixing clamp.

[0005] As a further embodiment of the present invention, the quick-adjusting buckle includes: A toothed adjusting belt is fixedly connected to one end of the fixed belt body; A collar is provided at the other end of the fixing belt body, and its interior has a through groove for the toothed adjusting belt to pass through; The locking plate is rotatably mounted on the fixed shaft of the collar via a return spring. The locking plate has teeth that engage with the limiting teeth on the toothed adjusting belt. By pressing or releasing the locking plate, the teeth can separate or engage with the limiting teeth, thereby quickly adjusting and locking the tension of the fixing belt.

[0006] As a further embodiment of the present invention, the arc-shaped fixing clamp is rotatably connected to the gear plate via a damping shaft, and there are also interlocking blocks and slots between the two to provide additional locking force when closed, preventing accidental opening.

[0007] As a further aspect of the invention, the inner side of the arc-shaped fixing clip is provided with a silicone anti-slip pad, and the surface of the silicone anti-slip pad is distributed with several micro-barbs. This design is used to increase the friction with the gastrostomy tube and prevent it from sliding.

[0008] As a further embodiment of the present invention, the telescopic locking mechanism includes a housing, a pressing rod, a locking pin, and a return spring. The housing is fixedly mounted on the main body of the fixing belt; the pressing rod is movably mounted inside the housing; one end of the locking pin is movably connected to the pressing rod, and the other end is telescopic; the edge of the gear disc has multiple equally spaced locking holes, and the locking pin cooperates with the locking holes to achieve locking or unlocking. The mechanism principle is similar to that of a push-button ballpoint pen, where pressing extends and retracts the locking pin.

[0009] As a further embodiment of the present invention, the outer periphery of the conduit hole is provided with a hook and loop fastener male side, and the bottom of the anti-fouling protective cover is provided with a hook and loop fastener female side. The two can be detachably glued together, which facilitates the cleaning, replacement or maintenance of the anti-fouling protective cover.

[0010] As a further embodiment of the present invention, the anti-fouling protective cover includes an upper cover and a lower cover. One end of both the upper and lower covers is hinged to the back of the Velcro face via a damping pivot, and their opposite sides have a detachable connection structure. When the upper and lower covers are closed, they form a closed space to protect the internal pipe joints. Symmetrical semi-circular grooves are formed at the center of opposite sides of both the upper and lower covers, and semi-circular sealing rings are provided within these grooves. When the covers are closed, the two semi-circular sealing rings tightly wrap around the gastrostomy tube extending from the center, forming a seal and providing auxiliary fixation.

[0011] As a further aspect of the present invention, the detachable connection structure includes a magnetic sealing strip. The upper and lower covers have mating grooves and protrusions on opposite sides, and magnetic sealing strips are provided on the opposite sides of both the grooves and protrusions. Magnetic closure is achieved, making operation convenient and providing a good seal.

[0012] As a further embodiment of the present invention, the anti-fouling protective cover also includes a soft support cover. A through groove is formed at the center of the outer wall of the soft support cover, which is parallel to the main body of the fixing strap. The through groove also has a detachable connecting structure (such as a magnetic sealing strip and a groove protrusion). This facilitates side access to the internal piping without completely disassembling the cover.

[0013] As a further aspect of the invention, the dustproof storage bag has an opening on its outer side, with a zipper at the opening and a guide tube fixing sticker inside. The zipper allows the bag to be closed, and the guide tube fixing sticker is used to secure the Y-shaped feeding head stored inside, preventing it from shaking.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the coordinated action of the toothed disc, arc-shaped fixing clamp, and telescopic locking mechanism, the gastrostomy tube can not only be firmly clamped, but also the tube's exit angle can be flexibly and precisely adjusted according to the patient's position or needs, avoiding twisting and pressure, and significantly improving patient comfort.

[0015] The quick-adjustment buckle, consisting of a toothed adjustment strap and a locking plate, is easy to operate and can be completed in one step. It solves the problem of cumbersome adjustment of traditional straps and improves the nursing efficiency of medical staff.

[0016] The removable protective cover completely encloses the gastrostomy tube interface, effectively preventing the intrusion of external liquids, dust, and bacteria, thus reducing the risk of infection. Its multi-component, multi-sealing design enhances the level of protection and facilitates cleaning and replacement.

[0017] By integrating a dustproof storage bag, a closed and hygienic storage space is provided for unused Y-shaped feeding heads, solving the problems of easy contamination, shaking, and pulling, and further ensuring the hygiene and safety of the pipeline.

[0018] The device features a user-friendly overall design and simplified operation, which reduces the workload of medical staff and improves the comfort and safety of patients, making it highly valuable for clinical use. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example

[0022] Please see Figures 1 to 11 This invention provides a gastrostomy tube fixation device with integrated Y-shaped feeding head storage, aiming to solve a number of problems in existing gastrostomy tube fixation methods.

[0023] The core components of this device include: a flexible fixation strap body 1 for wrapping around the patient's body; an anti-slip fixation structure 2 integrated in the middle of the fixation strap body 1; quick-adjusting buckles 3 located at both ends of the fixation strap body 1; a detachable anti-fouling protective cover 4 covering the anti-slip fixation structure 2 and the catheter hole 11; and a dustproof storage bag 5 located on one side of the anti-fouling protective cover 4.

[0024] The fixing strap body 1 has a catheter hole 11 for the gastrostomy tube to pass through. The two ends of the fixing strap body 1 are connected by quick-adjusting buckles 3. In this embodiment, the quick-adjusting buckle 3 includes a toothed adjusting strap 31 fixed at one end and a locking mechanism at the other end. The locking mechanism includes a collar with a fixed shaft and a through groove inside. The locking pressure plate 32 is mounted on the fixed shaft via a return spring 232 (this return spring can be shared with the locking mechanism 23 or set independently). The locking pressure plate 32 has toothed claws. In use, the toothed adjusting strap 31 is passed through the through groove, and pressing the locking pressure plate 32 disengages the toothed claws from the toothed groove, allowing the adjusting strap to be pulled freely; after release, the return spring 232 pushes the locking pressure plate 32 back to its original position, and the toothed claws engage the toothed groove, achieving self-locking.

[0025] The anti-dislodgement fixing structure 2 is the key component of this invention, used to fix the gastrostomy tube and adjust its angle. It includes a rotatable toothed disc 21, which is connected to the fixing strap body 1 via a shaft. An arc-shaped fixing clip 22 is mounted on the toothed disc 21 via a damping pivot 45 and is used to clamp the gastrostomy tube. The arc-shaped fixing clip 22 can rotate around the damping pivot to open and close, and its inner side is provided with a silicone anti-slip pad 221 with micro-barbs 222 to increase friction. The edge of the toothed disc 21 has multiple equally spaced locking holes 211. The telescopic locking mechanism 23 includes a housing 231, a pressing rod 234, a locking pin 233, and a return spring 232. The locking pin 233 and the pressing rod 234 are linked by an inclined plane. Press the lever 234 once, the locking pin 233 retracts, the gear plate 21 can rotate freely, and the arc-shaped fixing clamp 22 can swing to adapt to the pipeline direction; press again, the locking pin 233 extends and inserts into the locking hole 211, locking the angle of the gear plate 21 and the arc-shaped fixing clamp 22.

[0026] The anti-fouling protective cover 4 is detachably connected by bonding the female side 44 of the bottom Velcro to the male side of the outer periphery of the conduit hole 11 with the Velcro. In this embodiment, the anti-fouling protective cover 4 consists of an upper cover 41 and a lower cover 42 hinged by a damping pivot. When the upper and lower covers are closed, their opposite sides are sealed by magnetic sealing strips 43 (set in mutually mating grooves and protrusions), and a conduit outlet wrapped by two semi-circular sealing rings is formed at the center. This structure effectively prevents external contaminants from entering.

[0027] A dustproof storage bag 5 is placed next to the anti-fouling protective cover 4. It has a zipper 51 opening on the outside and a tube fixing sticker 52 inside. When the Y-shaped feeding head 6 is not in use, it can be placed in the bag, closed with the zipper 51, and fixed with the tube fixing sticker 52 to prevent it from shaking and being exposed.

[0028] Work process: In use, first, pass the gastrostomy tube through the catheter hole 11 of the fixing strap body 1. Wrap the fixing strap body 1 around the patient's body and secure it in the appropriate position using the quick-adjusting buckle 3. Next, open the arc-shaped fixing clip 22, place the gastrostomy tube inside, and close it for fixation; the silicone anti-slip pad 221 provides an anti-slip effect. Then, press the pressing lever 234 of the telescopic locking mechanism 23 according to the patient's position to unlock the toothed disc 21, rotate the arc-shaped fixing clip 22 to the most natural, undistorted angle of the gastrostomy tube, and press it again to lock it. Subsequently, secure the anti-fouling protective cover 4 with Velcro, and lead the gastrostomy tube out from the semi-circular groove 46 in the center of the upper and lower covers, closing the upper and lower covers. Finally, place the exposed Y-shaped feeding head 6 into the dustproof storage bag 5, zip it up and secure it. When it is necessary to adjust the gastrostomy tube or use the Y-shaped feeding head, the cover or zipper of the anti-fouling protective cover can be easily opened. Example

[0029] This embodiment further improves upon Embodiment 1 regarding the anti-fouling protective cover 4. Please refer to... Figure 5 and Figure 6 In this embodiment, the anti-fouling protective cover 4 also includes a soft support cover. The soft support cover has a through groove parallel to the center of the outer wall of the fixing belt body 1. The through groove has a detachable connection structure (such as a magnetic sealing strip and a groove). When it is necessary to adjust the internal pipeline from the side, simply manually open this through groove to expose the internal space; there is no need to fully open the upper and lower covers, making operation more convenient. After operation, release your hand, and the magnetic sealing strip will automatically close the through groove. Example

[0030] This embodiment optimizes the locking plate 32 of the quick-adjusting buckle 3 based on embodiment one or two. Anti-slip textures are provided on the surface of the locking plate 32, increasing the friction between the fingers and the plate, allowing medical personnel to apply force stably even when wearing gloves, preventing slippage and improving the accuracy and stability of the operation.

[0031] Based on the above embodiments and working principles, this invention, through the synergistic effect of the toothed disc, the arc-shaped fixing clamp, and the telescopic locking mechanism, can not only firmly clamp the gastrostomy tube, but also flexibly and precisely adjust the tube's exit angle according to the patient's position or needs, avoiding twisting and pressure, and significantly improving patient comfort.

[0032] This invention uses a quick-adjusting buckle composed of a toothed adjusting strap and a locking pressure plate, which is easy to operate and can be completed in one step. It solves the problem of cumbersome adjustment of traditional straps and improves the nursing efficiency of medical staff.

[0033] This invention completely encloses the interface of the gastrostomy tube with a detachable protective cover, effectively preventing the intrusion of external liquids, dust, and bacteria, thus reducing the risk of infection. Its multi-component, multi-sealing-ring design enhances the level of protection and facilitates cleaning and replacement.

[0034] This invention provides a closed and hygienic storage space for unused Y-shaped feeding heads by integrating a dustproof storage bag, solving the problems of easy contamination, shaking, and pulling, and further ensuring the hygiene and safety of the pipeline.

[0035] This device features a user-friendly overall design and simplified operation, reducing the workload of medical staff while improving patient comfort and safety, thus possessing high clinical practical value.
