Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an interventional catheter fixer for cardiovascular and cerebrovascular care. Background Art

[0002] Vascular interventional catheter treatment for patients with cardiovascular and cerebrovascular diseases requires the insertion of a very long catheter into the human body. Since the catheter is very long, in order to allow the catheter to enter the body smoothly, the catheter located outside needs to be fixed, usually with medical tape.

[0003] After searching, the patent application with Chinese patent publication number CN113456992B discloses an interventional catheter fixer for cardiovascular and cerebrovascular care, which mainly fixes the catheter through placement holes of different diameters, a first turntable, a first transmission shaft and a locking plate.

[0004] By comparing with the existing technologies in related fields, it can be seen that the existing catheter fixers need to select a suitable placement hole according to the diameter of the catheter before they can be fixed, which is relatively cumbersome to operate. In addition, the existing catheters and fixing components are exposed to the outside. During use, external factors will affect the fixation of the interventional catheter, causing the interventional catheter to move, increasing the risk during treatment. Utility Model Content

The slide plate is slidably connected to the protective enclosure, and a pressure sensor is installed on the lower surface of the slide plate.

[0010] Furthermore, the restraining unit on the protective enclosure includes a mounting seat and a restraining belt. The mounting seat is arranged on both sides of the protective enclosure, one end of the restraining belt is installed in the mounting seat, and the other end of the restraining belt is installed with an adjustment buckle.

[0011] Furthermore, ventilation holes are provided on the sides of the protective enclosure to increase the air permeability of the insertion position of the interventional catheter.

The patient is placed on the patient's body, the interventional catheter is fixed by the fixing unit 3, the protective enclosure 1 is covered and closed by the protective cover 2, the protective cover 2 and the protective enclosure 1 are fixedly connected together by the locking rod 7 and the locking seat 6, and the interventional catheter and the fixing unit 3 are shielded and protected by the protective cover 2 and the protective enclosure 1, so as to avoid the risk of the interventional catheter being displaced by the patient's private movement or accidental touching of the interventional catheter, thereby improving the safety and stability of the interventional catheter during use, reducing complications caused by the displacement of the interventional catheter, and ensuring the smooth progress of the treatment. During use, the position of the protective enclosure 1 is located by the detection unit 4. When the detection unit 4 detects that the patient has privately moved the protective enclosure 1, the information is transmitted to the doctor through the wireless signal transmission mechanism 15, so that the doctor can find out in time and stop the patient, thereby improving safety;

[0028] like Figure 1 , Figure 2 , Figure 4As shown, the fixing unit 3 in the protective enclosure 1 includes a support rod 301 and a three-jaw chuck mechanism 302.
