Abstract
Description
Technical Field
[0001] The present application relates to the field of medical care, and in particular to a catheter fixing device. Background Art
[0002] PICC catheterization is to use the PICC catheter to puncture the vein on the back of the patient's peripheral hand, so that the catheter can reach the large vein close to the heart, avoiding direct contact between chemotherapy drugs and the superficial veins of the arm, thereby reducing the damage of chemotherapy drugs to the peripheral veins. The fixation of the PICC catheter is particularly important. If the catheter is not firmly fixed, it may cause the catheter to fall out, break, and become infected.
[0003] See also Figure 1 , a fixing wing 11 is usually provided on the catheter 1. There are two main ways to fix the catheter 1 in the related art. One is to use a specific fixer for fixation, wherein the fixer mainly includes a base that can be adhered to the skin, and a snap-fit structure provided on the base that can form a snap-fit connection with the fixing wing. The purchase cost of this fixer is relatively high, and the snap-fit structure on the fixer is a convex structure. When a layer of transparent film is attached to the outside of the fixer, a certain cavity will be formed inside the transparent film, so that the transparent film is not sufficiently fitted to the skin, resulting in reduced wrapping. The other is to directly cover a layer of transparent film around the fixer, and add tape around the transparent film for secondary fixation. Since this method does not directly limit the catheter, the inventor found in the implementation of this method that the catheter will be pulled outward with improper activities of the patient (see Figure 1 ), causing the catheter to be dislodged. Utility Model Content
[0004] In view of this, the present application provides a catheter fixing device, which has a simple structure, low manufacturing cost, is easy to use, and has a good catheter fixing effect.
[0005] In order to achieve the above objectives, this application is implemented through the following technical solutions:
[0006] A catheter fixing device, characterized in that it comprises an anchoring portion and a stabilizing portion, wherein the lower surface of the anchoring portion is provided with a first adhesive for fixing the anchoring portion to the patient's skin;
[0007] There are two stabilizing parts, which are fixed to the anchoring part respectively, and a slit is reserved between the two stabilizing parts. The tube part of the catheter can be inserted into the slit and placed on the upper surface of the anchoring part; the two stabilizing parts can be folded to present a cross structure with one on top and the other on the bottom, and the two staggered stabilizing parts are used to wrap around the fixed wings of the catheter, and the lower surface of the head of the stabilizing part is provided with a second adhesive for fixing the head of the corresponding stabilizing part to the patient's skin, so that the roots of the two cross-arranged stabilizing parts can be snapped on the end of the fixed wing to limit the catheter from falling out, and one end of the head of the two stabilizing parts wraps around the two sides of the fixed wing from the two sides to limit the lateral deviation of the fixed wing.
[0008] The above-mentioned catheter fixing device of the present application can be adhered to the skin through the anchoring part. The tube part of the catheter is inserted into the slit between the two stabilizing parts and placed on the upper surface of the anchoring part. The two stabilizing parts are cross-folded and the two ends of the stabilizing parts are adhered to the skin, so that the root positions of the two stabilizing parts can clamp the ends of the fixed wings to limit the catheter from slipping out. The middle areas of the two stabilizing parts are pressed on the fixed wings, and one end of the head of the stabilizing part wraps the side of the fixed wings, so that the fixed wings can be stably wrapped therein, thereby achieving the purpose of fixing the catheter. And the stabilizing part wraps the fixed wings, and there is no additional outward protruding structure, so that when wrapping the transparent film, it can fit the skin better. In addition, the fixing device has a simple structure, is easy to operate, and has a low manufacturing cost.
[0009] In some embodiments, the anchoring portion is further provided with a tear line. The tear line is provided mainly to facilitate the later disassembly of the fixing device, and the number of the tear lines can be one, two or more. The tear line is usually provided in the form of a dotted line.
[0010] In some embodiments, the tear line is tilted toward one of the two sides of the anchoring portion. The purpose of tilting the tear line is to divide the anchoring portion into two areas, one large and one small. When the pulling force of the catheter is too large, the small area is usually destroyed first, while the large area can still be firmly connected to the skin and continue to keep the catheter fixed. It can be imagined that if the tear line is set in the middle position, the two areas formed will be of equal size, which may easily cause the problem of both areas being destroyed at the same time.
[0011] In some embodiments, the lower surface of the stabilizing portion is provided with a non-adhesive cushion layer in the area where the second adhesive is not provided. The stabilizing portion is not provided with adhesive in the area wrapping the fixed wing, mainly to prevent the adhesive layer from adhering to the catheter, which does not meet the requirements of the specification. Moreover, the cushion layer is provided in this area mainly to form a flexible connection with the fixed wing.
[0012] In some embodiments, the anchoring portion and the stabilizing portion are connected in one piece. The structure connected in one piece is simpler to manufacture.
[0013] In some embodiments, the anchoring portion and the stabilizing portion are made of breathable and hypoallergenic materials, such as gauze, non-woven fabrics, and the like.
[0014] In some embodiments, the lower surfaces of the anchoring part and the stabilizing part are further provided with a detachable isolation layer, wherein the isolation layer is provided mainly to prevent the adhesive from adhering to the outer packaging bag, and the isolation layer can be torn off during specific use.
[0015] It can be seen from the above technical solution that the present application has at least the following advantages and positive effects:
[0016] The present application provides a catheter fixing device, which can be adhered to the skin through an anchoring part. The tube of the catheter is inserted into the slit between the two stabilizing parts and placed on the upper surface of the anchoring part. The two stabilizing parts are cross-folded and the two ends of the stabilizing parts are adhered to the skin, so that the root positions of the two stabilizing parts can clamp the ends of the fixed wings to limit the catheter from slipping out. The middle areas of the two stabilizing parts are pressed on the fixed wings, and one end of the head of the stabilizing part wraps the side of the fixed wings, so that the fixed wings can be stably wrapped therein, thereby achieving the purpose of fixing the catheter. In addition, the stabilizing part wraps the fixed wings without any additional outward protruding structure, so that when wrapping the transparent film, it can fit the skin more closely. In addition, the fixing device has a simple structure, is easy to operate, and has a low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. The terms used in the implementation method of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.
[0023] See also Figures 1 to 4 , an embodiment of the present application provides a catheter fixing device, comprising an anchoring portion 2 and a stabilizing portion 3, wherein a first adhesive 21 is provided on the lower surface of the anchoring portion 2 for fixing the anchoring portion 2 to the patient's skin;
[0024] There are two stabilizing parts 3, which are fixed to the anchoring part 2 respectively, wherein the two stabilizing parts are distributed on the left and right, and a slit 4 is reserved between the two stabilizing parts 3, and the tube part 12 of the catheter 1 can be inserted into the slit 4 and placed on the upper surface of the anchoring part 2; the two stabilizing parts 3 can be folded to form a cross structure with one on the top and the other on the bottom, and the two staggered stabilizing parts 3 are used to wrap around the fixed wing 11 of the catheter 1, and the lower surface of the head of the stabilizing part 3 is provided with a second adhesive 31, which is used to fix the head of the corresponding stabilizing part 3 to the patient's skin, so that the roots of the two cross-arranged stabilizing parts 3 can be snapped on the end of the fixed wing 11 to limit the catheter 1 from falling out, and one end of the head of the two stabilizing parts 3 wraps around the two sides of the fixed wing 11 from the two sides to limit the lateral deviation of the fixed wing 11.
[0025] In this embodiment, the anchoring part 2 can be bonded to the skin, the tube part 12 of the catheter 1 is inserted into the slit 4 between the two stabilizing parts 3 and placed on the upper surface of the anchoring part 2. The two stabilizing parts 3 are cross-folded and the two ends of the stabilizing parts 3 are bonded to the skin, so that the root positions of the two stabilizing parts 3 can clamp the ends of the fixed wings 11 to limit the catheter 1 from slipping outwards, the middle areas of the two stabilizing parts 3 are pressed on the fixed wings 11, and one end of the head of the stabilizing part 3 wraps the side of the fixed wings 11, so that the fixed wings 11 can be stably wrapped therein, thereby achieving the purpose of fixing the catheter 1. In addition, the stabilizing part 3 wraps the fixed wings 11 without any additional outward protruding structure, so that when wrapping the transparent film, it can fit the skin more closely. In addition, the fixing device has a simple structure, is easy to operate, and has a low manufacturing cost.
[0026] In some embodiments, the anchoring portion 2 is further provided with a tear line 22.

[0027] In some embodiments, the tear line 22 is inclined toward one of the two sides of the anchoring portion 2. The purpose of the inclined setting of the tear line 22 is to divide the anchoring portion 2 into two areas, one large and one small. When the pulling force of the catheter 1 is too large, the small area is usually destroyed first, while the large area can still be firmly connected to the skin, and the catheter 1 continues to be fixed. It can be imagined that if the tear line 22 is set in the middle position, the two areas formed are of equal size, which easily causes the problem of both areas being destroyed at the same time.
[0028] In some embodiments, the lower surface of the stabilizing portion 3 is provided with a non-adhesive cushion layer 32 in an area where the second adhesive 31 is not provided. The stabilizing portion 3 is not provided with adhesive in an area wrapping the fixing wing 11, mainly to prevent the adhesive layer from adhering to the catheter 1, which does not meet the specification requirements. Moreover, the cushion layer is provided in this area mainly to form a flexible connection with the fixing wing 11.
[0029] In some embodiments, the anchoring portion 2 and the stabilizing portion 3 are integrally connected. The integrally connected structure is simpler to manufacture.
