Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical catheter fixing, in particular to a catheter fixing device. BACKGROUND

[0002] At present, in the clinic, when the minimally invasive drainage operation is completed, it is usually necessary to use the indwelling drainage catheter to continuously drain the effusion, and the fixation of the indwelling catheter is particularly important. In the actual use process, in order to prevent the indwelling catheter from moving or falling off, one way is to fix the indwelling catheter on the skin surface by sewing needle thread directly. This method needs to sew more parts, and the amount of sewing is large, which can easily increase the trauma of the tissue and increase the opportunity of tissue infection. Moreover, the traction of the suture thread on the tissue can also cause pain to the patient. Another way is to fix the indwelling catheter by using a non-woven fabric fixing patch. However, the friction between the non-woven fabric and the indwelling catheter is small, which can easily cause the catheter to slip out, and there is no support, which can cause the catheter to form a right angle with the skin, and can easily cause the catheter to be folded, resulting in poor drainage. Another way is to use a catheter fixing device. The catheter fixing device includes a pad and a tube sleeve connected to the pad, and the indwelling catheter penetrates through the tube sleeve. However, the tube sleeve is usually a hard structure, and the bending direction of the tube sleeve is fixed and can be adjusted, that is, the bending direction cannot be changed, and the catheter fixing device is not convenient to use.

[0035] Figure 1 A perspective structural schematic diagram of the catheter fixer provided by the embodiments of the present application is shown. Figure 2 Another view diagram of the catheter fixer provided by the embodiments of the present application is shown. Figure 3 A front view diagram of the catheter fixer provided by the embodiments of the present application is shown. The catheter fixer includes a sticking disc 1 and a tube sleeve 2, the sticking disc 1 is used for sticking to the skin, the tube sleeve 2 is connected to the sticking disc 1, the tube sleeve 2 and the sticking disc 1 are provided with a tube passing groove 21 and a deformation seam communicating with the tube passing groove 21, the tube sleeve 2 is provided with a plurality of deformation grooves 22, the deformation grooves 22 extend along the circumferential direction of the tube sleeve 2, and each of the deformation grooves 22 is sequentially arranged along the length direction of the tube sleeve 2. Under the action of an external force, the tube sleeve 2 can be bent and deformed to adapt to the actual tube leading angle requirement. In the state that the external force is removed, the tube sleeve 2 can restore the shape. Under the action of no external force, the tube sleeve 2 is substantially perpendicular to the sticking disc 1.

[0036] The catheter fixer of the present application has a tube sleeve 2 which is adapted to the catheter and is used for clamping the catheter, an internal tube passing groove 21 is used for passing and fixing the catheter (such as an indwelling catheter), and the tube sleeve 2 is provided with a deformation seam communicating with the internal tube passing groove 21, so that the tube sleeve 2 has good elasticity and can adapt to catheters with different outer diameters. Under the action of an external force, the deformation seam can be opened and the gap can be enlarged, so that the catheter can be conveniently loaded into the tube passing groove 21 through the deformation seam.

[0037] The tube sleeve 2 is provided with a plurality of deformation grooves 22 at intervals on the outer wall, so that the tube sleeve 2 is thinned at a plurality of intervals, has good bending deformation performance, and the setting density of the deformation grooves 22 is large enough, so that the tube sleeve 2 can be bent in any direction with a rounded corner, and the catheter can be prevented from being folded to cause poor drainage. The sticking disc 1 can be well stuck to the skin, and an adhesive such as a plaster can be used to stably and effectively paste the sticking disc 1 on the skin.

[0038] In some possible embodiments, each of the deformation grooves 22 extends to a deformation seam (i.e., the first deformation seam 25 in the following) on the sleeve 2. The deformation groove 22 extends along the circumference of the sleeve 2 to the outer surface of the sleeve 2, so that the sleeve 2 is thinned around the circumference and can be bent and deformed in any direction.

[0039] In some possible embodiments, the sleeve 2 has sleeve thickness sections 23 on both sides of the deformation seam, and the deformation groove 22 extends to the sleeve thickness sections 23. The deformation groove 22 extends to the thickness end surface of the sleeve 2, which extends the extension size of the deformation groove 22 and improves the bending and deformation performance of the sleeve 2.

[0040] In some possible embodiments, the sleeve 2 is provided with a fixed fitting groove 24 on one side close to the end.

[0041] The fixed fitting groove 24 is located at the end of the sleeve 2 away from the pad 1. The fixed fitting groove 24 can facilitate the fastening of the buckle to fix the extension direction of the sleeve 2 and the catheter. The medical staff can bend the sleeve 2 and the catheter in the corresponding direction according to the actual situation. For example, the adhesive piece can be wound around the fixed fitting groove 24, and the two ends are respectively adhered to the pad 1 or the skin. The sleeve 2 has a restoring deformation capability, and the elastic direction of the restoring deformation of the sleeve 2 is opposite to the external force applied by the adhesive piece, so that the sleeve 2 is stably fixed and is not easily deformed.

[0042] In some possible embodiments, the groove width of the fixed fitting groove 24 is greater than the groove width of the deformation groove 22. In this embodiment, the groove width of the fixed fitting groove 24 is increased in adaptability, and the cooperation with the buckle structure is more convenient. The groove depth of the fixed fitting groove 24 can be substantially matched with the groove depth of the deformation groove 22. When the fixed fitting groove 24 cooperates with the buckle structure (such as an adhesive piece or other adhesive structure), the sleeve 2 is not easy to be detached, and the reliability of the fixed structure of the fixed catheter is improved.

[0043] The catheter fixer of the present application can be made of soft rubber material, for example, the catheter fixer can be a silicone piece, a rubber piece or other plastic pieces with soft material.

[0044] In some possible embodiments, each of the deformation grooves 22 is located between the fixed fitting groove 24 and the pad 1.

[0045] The fixed fitting groove 24 is located at the end of the sleeve, which is not used for bending, and the area between the fixed fitting groove 24 and the pad 1 is the part that needs to be bent and deformed, so each deformation groove 22 is arranged between the fixed fitting groove 24 and the pad 1, and each deformation groove 22 can be uniformly and equidistantly arranged along the length direction of the sleeve 2.

[0046] In some possible embodiments, the deformation slot includes a first deformation slot 25 arranged on the tube sleeve 2, the first deformation slot 25 extends along the length direction of the tube sleeve 2, and the width of the first deformation slot 25 gradually increases from the center line of the tube sleeve 2 to the outer wall of the tube sleeve 2.

[0047] The width of the deformation slot is small near one side of the pipe passing groove 21, and the width of the deformation slot is large on the side outside the tube sleeve 2, thereby having a guiding effect, facilitating the smooth movement of the catheter from the side outside the deformation groove 22 to the side of the pipe passing groove 21, and finally moving completely into the pipe passing groove 21.

[0048] In some possible embodiments, the deformation slot includes a second deformation slot 11 arranged on the patch 1, the second deformation slot 11 is connected to the first deformation slot 25, the second deformation slot 11 extends from the first deformation slot 25 to the edge of the patch 1, and the second deformation slot 11 penetrates the patch 1 along the thickness direction of the patch 1.

[0049] In the process of fixing the catheter, opposite forces can be applied on both sides of the second deformation slot 11 on the patch 1 first, so that the patch 1 is opened at the second deformation slot 11, and the first deformation slot 25 is also opened, at this time, the catheter can be moved along the second deformation slot 11 to the tube sleeve 2, and then smoothly moved into the pipe passing groove 21 through the first deformation slot 25, and finally the external force is removed, and the tube sleeve 2 can clamp and fix the catheter.

[0050] In some possible embodiments, the patch 1 is provided with a suture fixing hole 12, which can be selected according to actual conditions. When the patch 1 is not stable by adhesive bonding, the patch 1 can be sutured to the human skin by means of the suture fixing hole 12, thereby improving the effect of stable fixation.

[0051] In some possible embodiments, the patch 1 is provided with a breathable hole 13. The breathable hole 13 can make the skin covered by the patch 1 contact the air, thereby avoiding the increase of the cutin layer of the skin, the growth of acne, and the breeding of bacteria.
