Description

Technical Field

[0001] The utility model relates to the technical field of interventional catheter fixation, and particularly relates to an interventional radiology catheter fixator. Background Art

[0002] Interventional radiology is to insert a special catheter or instrument into the lesion site for diagnostic angiography and treatment through a skin puncture approach or through the original body orifice under the guidance of imaging medicine (X-ray, ultrasound, CT, MRI). However, after the treatment, the catheter needs to be placed in the body for a period of time.

[0003] In the prior art, in order to prevent the catheter from slipping out, generally medical staff will use adhesive strips or directly sew the catheter to the affected area of the patient for fixation. The former has unstable fixation and is easy to slip out, while the latter is easy to cause wound infection and is not conducive to the recovery of the patient; although there are some current fixation methods that directly use clips to clamp the catheter, a simple clip cannot guarantee stability. When the patient makes a large movement or is accidentally touched by others, it is extremely easy to loosen, which will lead to wound infection and inflammation, and is also not conducive to the recovery of the patient. At the same time, the current clips have relatively single functions and do not have a fine-tuning mechanism. When the clip clamps, there will still be a loosening phenomenon, which is not conducive to fixing the catheter. Therefore, in order to improve the stability of catheter fixation and prevent the catheter from slipping out after fixation, it is necessary to improve the catheter fixation device in the prior art. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an interventional radiology catheter fixator to solve the problems raised in the above background art.

[0005] To solve the above problems, the technical solutions adopted by the utility model are as follows:

[0006] An interventional radiology catheter fixator, comprising

[0007] A fixing patch, a bent strip is fixedly connected to the fixing patch, and the bent strip is used for wrapping and binding an interventional catheter;

[0008] A soft rubber pad, the soft rubber pad is fixedly installed on the inner wall of the bent strip and makes flexible contact with the outer wall of the interventional catheter;

[0009] Teeth, a plurality of the teeth are fixedly arranged at equal intervals on the outer wall of the bent strip;

[0010] A flexible rod, one end of the flexible rod is fixedly connected to the upper wall of the fixing patch;

[0011] A clamping plate, the clamping plate is fixedly arranged at the upper end of the flexible rod, and one end of the clamping plate is clamped between two adjacent teeth;

[0012] The first card slot is opened on the outer wall of the bent strip;

[0013] The second card slot is opened on the outer wall of the soft rubber pad.

[0014] Preferably, the central axes of the first card slot and the second card slot coincide, and the handle ears of the intervention catheter are engaged inside the first card slot and the second card slot.

[0015] Preferably, a handle end is fixedly connected to the outer wall of the bent strip.

[0016] Preferably, the bent strip, the teeth, the flexible rod and the clamping plate are all made of soft plastic.

[0017] Preferably, an anti-misoperation box is fixedly connected to the fixing sticker, and the clamping plate and the flexible rod are both arranged inside the anti-misoperation box.

[0018] Preferably, a limiting jack is opened on the upper wall of the teeth, a limiting insertion rod is fixedly connected to the lower wall of the clamping plate, and the limiting insertion rod is inserted and connected with the limiting jack.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] By placing the handle ears arranged on the outer wall of the intervention catheter in the first card slot and the second card slot, the utility model is convenient for initially fixing the intervention catheter. Then, the medical staff bends the bent strip, so that the bent strip is wound and reduced to wrap the outer wall of the intervention catheter. Further, by utilizing the characteristic that one end of the clamping plate is clamped between two adjacent teeth, it is convenient to fix the intervention catheter by using the bent strip, and the intervention catheters with different specifications and sizes can be fixed.

[0021] In order to further fix and restrain the intervention catheter, a limiting jack is opened on the upper wall of the teeth, and a limiting insertion rod is fixedly connected to the lower wall of the clamping plate. When the medical staff uses one end of the clamping plate to limit the bending shape of the bent strip, the limiting insertion rod can be further inserted into the limiting jack, thereby strengthening the fixation of the intervention catheter, and the fixation operation of the intervention catheter is convenient and fast.
