A catheter securement device

Abstract

This utility model discloses a catheter fixation device, including an adhesive part and a catheter fixator connected to the adhesive part. The adhesive part includes an adhesive layer and an anti-adhesive layer. A release layer is detachably connected to the lower surface of the adhesive layer. The adhesive layer is composed of a non-woven fabric substrate and self-adhesive silicone gel. The catheter fixator includes a base connected to the upper surface of the anti-adhesive layer and a catheter fixing clip rotatably connected to the base. The non-woven fabric substrate coated with self-adhesive silicone gel is used as the adhesive layer, and its surface properties significantly reduce the adhesion to hair. Compared with traditional adhesive materials, it can effectively avoid sticking to the patient's body hair when pasting, adjusting, or removing the device, significantly reducing the patient's pain and discomfort, and improving the comfort of use. At the same time, the adhesive part is very firm when it is peeled off from the patient and then immediately re-pasted, thus preventing secondary detachment; while the adhesive of traditional catheter fixation tape is greatly reduced after being peeled off from the patient, and it is easy to detach again when re-pasted.

Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a catheter fixation device. Background Technology

[0002] In clinical practice, indwelling catheters are a widely used medical procedure. To ensure the catheter is safely, effectively, and permanently fixed on the patient's body surface and to prevent accidental slippage or displacement, specialized catheter fixation devices are required.

[0003] Catheter fixation patches are common catheter fixation devices. These devices typically consist of an adhesive part and a clamping structure for holding the catheter. The adhesive part attaches to the patient's skin, while the clamping structure secures or holds the catheter. However, existing catheter fixation devices of this type still have some technical issues that require improvement:

[0004] 1. When changing the placement of the catheter fixation patch after it has been applied to the body, peeling it off can be problematic. The adhesive, having come into contact with the patient's skin, becomes significantly less sticky due to sweat and oil, affecting the fixation effect. Additionally, the adhesive can adhere firmly to hair on the skin, pulling out hair and causing pain when removing the patch. Furthermore, some products may leave adhesive residue on the skin after use, further impacting patient comfort.

[0005] 2. Fixation clips are typically fixed directly to the adhesive surface or via simple connectors. This connection method often limits the angle adjustment capability of the fixation clip relative to the adhesive surface. When it is necessary to adjust the angle of the fixation clip according to the catheter's direction or changes in the patient's position, existing devices usually lack a convenient and stable adjustment mechanism, resulting in either difficulty in adjustment or insecure fixation after adjustment. A common solution is to completely detach and re-attach the fixation device, which is not only cumbersome and increases consumable costs, but more importantly, frequent detachment and reattachment can damage the patient's skin.

[0006] This utility model is based on the above-mentioned circumstances. Utility Model Content

[0007] This invention overcomes the shortcomings of the prior art and provides a duct fixing device that does not stick to lint and can be washed with water after use to restore the adhesive layer to its adhesiveness.

[0008] This utility model is achieved through the following technical solution:

[0009] A catheter fixation device includes an adhesive part and a catheter fixator connected to the adhesive part. The adhesive part includes an adhesive layer and an anti-adhesive layer connected to the upper surface of the adhesive layer. A release layer is detachably connected to the lower surface of the adhesive layer. The adhesive layer is composed of a non-woven fabric substrate and a self-adhesive silicone gel coated on the non-woven fabric substrate. The catheter fixator includes a base connected to the upper surface of the anti-adhesive layer and a catheter fixing clamp rotatably connected to the base.

[0010] As described above, a catheter fixing device includes a connecting seat rotatably connected to a base. The connecting seat has a first slot for inserting a catheter. A locking cover that cooperates with the connecting seat to fix the catheter in the first slot is also rotatably connected to the connecting seat. A limiting structure that restricts the opening of the locking cover is provided between the locking cover and the connecting seat.

[0011] As described above, in a catheter fixing device, the connecting seat is provided with a first limiting protrusion that extends into the first slot to further fix the catheter.

[0012] As described above, in a catheter fixing device, the locking cover is provided with a second limiting protrusion that can further fix the catheter.

[0013] As described above, in a catheter fixing device, the locking cover is provided with a second slot that can cooperate with the first slot to place the catheter, and the second limiting protrusion is provided on the groove wall of the second slot.

[0014] As described above, a catheter fixing device has an insertion end and an extension end for the catheter to pass through, and a partition structure between the locking cover and the connecting seat is provided to separate the insertion end and / or the extension end into at least two ports.

[0015] As described above, the catheter fixing device includes a partition structure comprising a first partition block disposed on the bottom of a first slot and a second partition block disposed on the bottom of a second slot.

[0016] As described above, a catheter fixing device is provided between the first partition block and the second partition block, which allows the two to be inserted into each other.

[0017] As described above, a catheter fixing device includes a first locking block on a locking cover, a lever block with a certain elasticity on a connecting seat, and a second locking block that can disengage from the first locking block when the lever block is pried outward and engage with the first locking block when the locking cover is brought closer to the connecting seat.

[0018] As described above, in a catheter fixing device, the adhesive part is provided with a plurality of vent holes for ventilation.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This invention uses a non-woven fabric substrate coated with self-adhesive silicone gel as the adhesive layer, whose surface properties significantly reduce adhesion to hair. Compared to traditional adhesive materials, it effectively avoids sticking to the patient's body hair when attaching, adjusting, or removing the device, significantly reducing patient pain and discomfort and improving user comfort. Furthermore, the adhesive is firmly attached even after being peeled off the patient, preventing secondary detachment; whereas traditional catheter fixation tape loses its adhesiveness significantly after being peeled off, making it prone to secondary detachment upon re-attachment.

[0021] The self-adhesive silicone gel of the adhesive part is washable. When the adhesive layer becomes less sticky due to sweat, sebum, or dust, it can be cleaned by rinsing with gentle water. After cleaning, allow it to air dry or gently wipe it dry, and the adhesive layer will effectively restore most of its initial stickiness, enabling safe and repeated application of the device. This significantly extends the effective lifespan of a single product, reduces replacement frequency, and consequently lowers long-term nursing costs and medical consumable consumption for patients.

[0022] The rotatable design of the catheter clamp facilitates quick and flexible clamping of catheters in different extension directions, ensuring that the catheter remains stable and securely fixed in various activity states, preventing slippage or displacement. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figures 1 to 6The catheter fixation device shown includes an adhesive part 1 and a catheter fixator 2 connected to the adhesive part 1. The adhesive part 1 includes an adhesive layer 3 and an anti-adhesive layer 4 connected to the upper surface of the adhesive layer 3. A release layer 5 is detachably connected to the lower surface of the adhesive layer 3. The adhesive layer 3 is composed of a non-woven fabric substrate and a self-adhesive silicone gel coated on the non-woven fabric substrate. The catheter fixator 2 includes a base 21 connected to the upper surface of the anti-adhesive layer 4 and a catheter fixing clip 22 rotatably connected to the base 21.

[0032] This invention uses a non-woven fabric substrate coated with self-adhesive silicone gel as the adhesive layer 3, whose surface properties significantly reduce adhesion to hair. Compared to traditional adhesive materials, it effectively avoids sticking to the patient's body hair when attaching, adjusting, or removing the device, significantly reducing patient pain and discomfort and improving user comfort. The self-adhesive silicone gel of the adhesive part 1 is washable. When the adhesive layer surface becomes less sticky due to sweat, sebum, or dust contamination, it can be cleaned by rinsing with gentle water. After cleaning, the adhesive layer 3 can effectively restore most of its initial stickiness after air drying or gentle wiping, enabling safe and repeated attachment and use of the device. This significantly extends the effective lifespan of a single product, reduces replacement frequency, and thus lowers the long-term nursing costs and medical consumable consumption for patients. The rotatable design of the catheter clamp 22 facilitates quick and flexible clamping of catheters in different extension directions, ensuring stable and secure fixation of the catheter in various activity states and preventing slippage or displacement.

[0033] In one embodiment, the adhesive part 1 can be elliptical, arc-shaped, or square, or of course, other shapes.

[0034] In one embodiment, the catheter clamp 22 includes a connecting seat 221 rotatably connected to a base 21. The connecting seat 221 has a first slot 222 for inserting a catheter. A locking cover 223 is also rotatably connected to the connecting seat 221, which cooperates with the connecting seat 221 to fix the catheter in the first slot 222. A limiting structure 6 is provided between the locking cover 223 and the connecting seat 221 to prevent the locking cover 223 from opening. The base 21 can be attached to the anti-adhesive layer 4 with PUR adhesive. Compared with the current use of 502 glue, PUR adhesive is more flexible after curing, thereby reducing patient discomfort.

[0035] Furthermore, the connecting seat 221 is provided with a first limiting protrusion 224 that extends into the first slot 222 to further fix the conduit. The locking cover 223 is provided with a second limiting protrusion 225 that can further fix the conduit. This restricts the conduit from sliding within the slot and improves the fixing effect. Furthermore, the connecting seat 221, locking cover 223, first limiting protrusion 224, and second limiting protrusion 225 are integrally injection molded.

[0036] Furthermore, the base 21 is provided with a connecting shaft 211, and the connecting seat 221 is provided with a through hole 210 for the connecting shaft 211 to pass through. The end of the connecting shaft 211 is provided with a limiting block 2111 to prevent the connecting seat 221 from disengaging. Furthermore, the connecting shaft 211 is a hollow shaft, and the end of the connecting shaft 211 is provided with a cut 2112 for the limiting block 2111 to move towards the center.

[0037] In one embodiment, the first limiting protrusion 224 and the second limiting protrusion 225 are frustum-shaped. Of course, they can also be hemispherical or other shapes.

[0038] Furthermore, the locking cover 223 is provided with a second slot 226 that can cooperate with the first slot 222 to place the conduit, and the second limiting protrusion 225 is provided on the slot wall of the second slot 226.

[0039] In one embodiment, the first slot 222 and the second slot 226 are provided with an inlet end and an outlet end through which the conduit passes. A partition structure is provided between the locking cap 223 and the connecting seat 221 to separate the inlet end and / or the outlet end into at least two ports. This allows for a tighter connection between the conduit and the conduit clamp 22, reducing mutual interference between different conduits. Furthermore, the first slot 222 and the second slot 226 are tapered grooves that gradually narrow from the inlet end to the outlet end, thus adapting to the shape of the multi-port conduit.

[0040] In one embodiment, the partition structure includes a first partition block 71 disposed on the bottom of the first slot 222 and a second partition block 72 disposed on the bottom of the second slot 226. A plug-in structure is provided between the first partition block 71 and the second partition block 72 for insertion. The plug-in structure includes a socket 70 on the second partition block 72 and a pin 700 on the first partition block 71 that can be inserted into the socket 70, thereby making the connection between the locking cover 223 and the connecting seat 221 more secure.

[0041] In one embodiment, the partition structure divides the inlet and / or outlet into three ports; in another embodiment, the partition structure divides the inlet and / or outlet into two ports, or other numbers of ports may also be used.

[0042] In one embodiment, the limiting structure 6 includes a first locking block 61 disposed on the locking cover 223, and a flexible actuating block 62 disposed on the connecting seat 221. The actuating block 62 is provided with a second locking block 63 that can disengage from the first locking block 61 when the actuating block 62 is pried outward, and engage with the first locking block 61 when the locking cover 223 is brought closer to the connecting seat 221, thereby opening or closing the locking cover 223. The actuating block 62 and the connecting seat 221 are integrally formed.

[0043] In one embodiment, the locking cap 223 is provided with an indicator arrow 2230 for indicating the direction of conduit flow.

[0044] In one embodiment, the adhesive part 1 is provided with a plurality of ventilation holes 8 for ventilation, thereby improving the comfort of using the device.

[0045] In some embodiments, the release layer 5 may be a PE release film, or it may be made of other materials that facilitate release.

[0046] In some embodiments, the anti-adhesive layer 4 can be a PU film. Of course, it can also be made of other waterproof materials.
