Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a fixing device for a cervical blood vessel puncture guide wire. Background Art
[0002] Modern medicine has made neck vascular access very common. In various clinical scenarios, multiple lines, such as arterial sheaths, central venous catheters, pulmonary artery catheters, and jugular venous drainage tubes, may need to be inserted through the neck arteries and veins. Because the neck access area is narrow, any subsequent vascular access after the first line is placed could damage previously inserted lines. Therefore, when multiple vascular accesses are required, clinicians must carefully monitor the guidewires already inserted into each access point and advance each catheter sequentially along the guidewires. This approach of placing multiple guidewires first and then advancing the catheters sequentially can prevent accidental catheter insertion and damage. Furthermore, guidewires should be inserted only at a limited depth, as this can directly impact the heart and result in a significant length of guidewire remaining outside the skin. However, because neck access does not allow for a wide, flat working area, this complex procedure often results in guidewire dislodgement or contamination from the guidewire tail. Utility Model Content
[0003] The utility model aims to overcome the deficiencies in the prior art and provides a device for fixing a cervical blood vessel puncture guide wire, which not only facilitates operations such as guide wire fixation and release in a sterile area, but also avoids additional damage to the patient.
[0004] To achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions: a fixation device for a cervical blood vessel puncture guidewire, comprising a fixation body, wherein both sides of the fixation body are provided with wire threading tubes along the transverse direction thereof, forming an overall fixation device structure, the wire threading tube at the ear inlet end is provided with a guidewire insertion opening along the transverse direction thereof, and an adhesive layer is provided at the bottom of the fixation body.
[0005] Furthermore, the shape of the fixer body is rectangular, and the wire threading tubes are placed on both sides of the rectangle to form an integral structure.
[0006] Furthermore, the fixing device is made of plastic material.
[0007] Furthermore, the holder body has a length of 50 mm, a width of 20 mm and a thickness of 3 mm.
[0008] Furthermore, the outer diameter of the wire threading tube is 4 mm and the inner diameter is 2 mm.
[0009] Furthermore, the width of the opening for the wire guide of the ear-entry wire tube is 1 mm.
[0010] Furthermore, the adhesive layer is made of medical double-sided sticker.
[0011] Beneficial effects: Compared with the existing technology, the present invention avoids the possibility of accidentally puncturing other catheters during continuous neck vascular puncture operations. It also prevents insufficient sterile operating space, which may lead to guidewire contamination and guidewire dislocation. Clinically, it frees the operator's hands, making the operation simpler and faster. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Working process
[0024] See attached for details Figure 3 ,
[0025] 1. During clinical neck vascular puncture, first locate the neck vessels using surface positioning or ultrasound guidance, and insert the guidewire 5 to the appropriate depth;
[0026] 2. The guide wire placed outside the body is inserted into the tube through the guide wire insertion opening of the wire insertion tube. The distal end of the guide wire is bent and then inserted into the wire insertion tube at the distal ear.
[0027] 3. Tear off the anti-sticking paper of the medical double-sided sticker and stick it on the skin or sterile sheet to complete the fixation;
[0028] 4. When the guide wire needs to be released, pull the distal end of the guide wire out of the wire threading port at the distal ear, and pull the guide wire out of the "C"-shaped bayonet at the proximal ear to completely separate the guide wire from the fixator;
[0029] 4. After the puncture is completed, tear off the fixing device.
