AI Technical Summary
In the prior art, HAIC treatment lacks an effective fixation method between the sheath, catheter and microcatheter, which causes them to easily displace or fall off when the patient's position changes or moves, affecting the treatment effect and limiting the patient's activities.
A special device including a strap, a fixing bottom belt, a tube fixing clip and a coating patch is designed. By combining the strap and a fixing bottom belt, the sheath, catheter, and a micro-catheter are fixed by using a tube fixing clip and a coating patch to achieve relative fixation between the three.
Effectively prevent the displacement and fall of sheaths, catheters and microcatheters from displaced and falling off, ensure the treatment effect, and reduce patient activity restrictions.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a special device for fixing a vascular sheath and a catheter for HAIC treatment. Background Art
[0002] Hepatic arterial chemotherapy (HAIC) involves the use of an interventional technique to deliver chemotherapy drugs directly to the tumor-feeding artery via hepatic artery catheterization, targeting liver cancer cells. The hepatic artery catheterization consists of a sheath, a catheter, and a microcatheter. The catheter is placed inside the sheath, the microcatheter is placed inside the catheter, and the portion remaining outside the body is longer than the sheath, while the microcatheter is longer than the catheter.
[0003] In order to prevent the patient from shifting and loosening after the hepatic artery catheter is inserted, it needs to be fixed. Since the sheath, catheter and microcatheter of the hepatic artery catheter are independent of each other and movable, there is currently no more effective fixation method or special fixation device to effectively fix the three, so as to prevent the positions of the three from shifting due to the patient's body position or normal activities, and to ensure a good perfusion treatment effect. Currently, clinical nursing uses gauze covering and then fixing with elastic tape, but its effective time is very short and it is easy to shift or fall off, affecting the perfusion treatment effect and greatly restricting the patient's activities. Utility Model Content
[0004] The utility model provides a special device for fixing the vascular sheath and catheter in HAIC treatment. The device can solve the problem that the sheath, catheter, and microcatheter, which are independent of each other, cannot be effectively fixed during hepatic artery cannulation. The device provided by the utility model can keep the positions of the three relatively fixed, avoiding displacement and loosening after catheterization.
[0005] In order to achieve the above technical objectives, the present invention is implemented through the following technical solutions:
[0006] A special device for fixing vascular sheaths and catheters for HAIC treatment, comprising: a bandage, a fixing base band, a tube fixing clamp, and a covering patch;
[0007] A fixed bottom belt is detachably mounted on the strap, and the fixed bottom belt is perpendicular to the strap;
[0008] A plurality of pipe fixing clips are detachably mounted on the fixing bottom belt;
[0009] A detachable covering film sticker on the upper side of the fixed bottom belt;
[0010] Preferably, the strap is an elastic band, with Velcro provided at both ends of the strap; a detachable auxiliary elastic band is provided between the strap and the fixed bottom band;
[0011] Preferably, a buckle bottom is connected to the middle part of the strap;
[0012] Preferably, the fixing bottom straps include leg fixing bottom straps and wrist fixing bottom straps;
[0013] Preferably, buckle pins are provided on the corresponding buckle bottoms of the leg fixing bottom strap and the wrist fixing bottom strap;
[0014] Preferably, a tube placement groove is provided in the middle of the upper surface of the tube fixing clamp; and the inner diameter of the tube placement groove can be set to three sizes according to the outer diameters of the sheath tube, catheter, and microcatheter;
[0015] Preferably, the side edge of the upper surface of the tube fixing clamp is connected to an overlay patch; an adhesive material is provided on the overlay patch;
[0016] Preferably, the upper covering sticker is provided with soft convex strips; after the pipeline is placed in the pipeline groove, it is covered by the upper covering sticker, and the soft convex strips further fix the pipeline;
[0017] Preferably, a fixing adhesive is provided on the bottom surface of the tube fixing clamp; the fixing tube clamp can be connected to the fixing bottom belt by the fixing adhesive.
[0018] The beneficial effects of the utility model are:
[0019] The utility model is used to fix the sheath tube, catheter and microcatheter inserted through the hepatic artery. Since the sheath tube, catheter and microcatheter are nested and gradually extended with each other, the fixed points need to be dispersed. The fixed bottom belt of the device is long and can be provided with tube fixing clips of corresponding tube sizes and the number of tube fixing clips according to the positions of the sheath tube, catheter and microcatheter. The tube fixing clips are used on the fixed bottom belt to fix three independent and movable tubes at the same time, thereby achieving fixation between the three tubes, preventing their relative positions from moving and preventing the risk of tube displacement and tube detachment.
[0020] The fixing bottom straps are respectively provided with leg fixing bottom straps and wrist fixing bottom straps, which can adapt to the use of the device on the legs or wrists. BRIEF DESCRIPTION OF THE DRAWINGS
