Description

Technical Field

[0001] The utility model relates to a catheter fixator. Background Art

[0002] Internal jugular vein catheterization is a type of deep vein catheterization. It is used to quickly open a large vein channel for emergency rescue treatments such as infusion and blood transfusion. It is used to monitor the central venous pressure and guide the amount of fluid replacement. When long-term fluid replacement is required or the peripheral vein conditions are poor, venous puncture catheterization should also be performed. After the internal jugular vein catheter is implanted, it is usually necessary to fix the internal jugular vein catheter to prevent the catheter from falling off.

[0003] When fixing the internal jugular vein catheter, medical adhesive tape is generally used for fixation. However, for the convenience of using the internal jugular vein catheter, the medical adhesive tape can generally only be fixed at the front end of the catheter and cannot fix the entire internal jugular vein catheter, usually not firmly enough. In addition, the internal jugular vein catheter is usually directly exposed to the outside and is easily contaminated after being outside for a long time. Therefore, how to better fix the internal jugular vein catheter and avoid the internal jugular vein catheter from being contaminated is an important problem to be solved in the design of the catheter fixator. Content of the Utility Model

[0004] The utility model provides a catheter fixator to solve the problems of better fixing the internal jugular vein catheter and avoiding the internal jugular vein catheter from being contaminated.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] The utility model provides a catheter fixator, which includes an internal jugular vein catheter, and further includes:

[0007] A fixing and protecting structure, which is arranged on the outer side of the internal jugular vein catheter and fixes and protects the internal jugular vein catheter from pollution;

[0008] An opening and closing structure, which is arranged on the fixing and protecting structure;

[0009] A clamping structure, which is arranged on the opening and closing structure.

[0010] Preferably, the fixing and protecting structure includes a straight tube, a telescopic tube and an ear loop rope. One end of the straight tube is fixedly connected to the outer wall of the internal jugular vein catheter, the other end of the straight tube is fixedly connected to one end of the telescopic tube, and both ends of the ear loop rope are fixedly connected to the other end of the telescopic tube.

[0011] In this technical solution, the straight tube is sleeved outside the jugular vein catheter, which can protect the jugular vein catheter from pollution and prevent the jugular vein catheter from being contaminated when not in use. Stretch the telescopic tube so that the ear loop rope at the end of the telescopic tube is sleeved on the ear on the same side as the jugular vein catheter. The telescopic tube can hold the straight tube well through the ear loop rope, avoiding the dropping of the jugular vein catheter. At the same time, the telescopic tube can be stretched and retracted without affecting the movement of the patient's head.

[0012] Preferably, the other end of the telescopic tube is set to a closed structure.

[0055] The clamping rod 611 is clamped within the clamping groove 602 on the plug-in block 601 to restrict the plug-in block 601.

[0056] When the present utility model is in use, the straight tube 201 is sleeved outside the jugular vein catheter 1, which can protect the jugular vein catheter 1 from pollution and prevent the jugular vein catheter 1 from being contaminated when not in use. When fixing the jugular vein catheter 1, the medical double-sided tape 5 is pasted on the skin of the patient's neck for fixation. Then, stretch the telescopic tube 202 so that the ear loop rope 203 at the end of the telescopic tube 202 can be sleeved on the ear on the same side as the jugular vein catheter 1. The telescopic tube 202 can be well pulled by the ear loop rope 203, and the telescopic tube 202 can well pull the straight tube 201 to prevent the jugular vein catheter 1 from falling. At the same time, the telescopic tube 202 can be telescoped without affecting the movement of the patient's head, thus better fixing the jugular vein catheter 1 and preventing the jugular vein catheter 1 from falling.

[0057] When the jugular vein catheter 1 needs to be used, push the pulling plate 614. The pulling plate 614 slides within the square groove 311. The pulling plate 614 pulls the connecting rope 613. The connecting rope 613 pulls the clamping rod 611. The sliding block 615 moves along with the movement of the clamping rod 611. The spring 612 is compressed. The clamping rod 611 moves out of the clamping groove 602 and retracts into the sliding placement groove 313. The plug-in block 601 is no longer restricted. Push the connecting block 302, and the plug-in block 601 can be separated from the plug-in groove 312. The separation of the two connecting blocks 302 causes the two opening and closing arc plates 301 to rotate and open to both sides, exposing the jugular vein catheter 1. Take out the jugular vein catheter 1 and connect the external catheter for use. After use, put the jugular vein catheter 1 back into the straight tube 201 again, close the opening and closing arc plates 301, and the clamping rod 611 is re-clamped within the clamping groove 602 on the plug-in block 601 to restrict the plug-in block 601.
