Description

central venous access fixer

technical field

The utility model relates to a medical auxiliary device, in particular to a central vein puncture fixer.

Background technique

Central venous puncture and indwelling central venous catheter is a basic technique commonly used in clinical practice. For patients with acute and chronic renal failure who need to establish a central venous for blood purification, critically ill patients with multiple organ dysfunction or those who need long-term infusion, central venous catheter is the best choice for patients. Lifeline, cardiovascular medicine often requires central venous interventional treatment. Commonly used indwelling veins are the internal jugular, subclavian, and femoral veins. Improper central venous puncture often leads to complications such as hematoma, pneumothorax, and hemothorax, and even hematoma can compress the trachea and cause death. Fix the patient in an appropriate position during puncture, especially when the central venous needle has penetrated into the central vein and is waiting to be placed. The moment when the guide wire is inserted is of great significance for improving the safety of central venous puncture. The existing method of fixing the patient's position is to tell the patient to maintain the position by himself, but the patient often turns his head, tilts his neck, involuntarily moves his limbs, twists his body and changes his position after laying a sterile towel, due to fear of pain and mental stress. , so that the anatomical position of the predetermined mark of central venous puncture changes, and it is difficult to maintain an appropriate body position for close cooperation, so that the puncture is easy to damage important structures, resulting in puncture failure, and even life-threatening serious consequences.

Contents of the invention

The purpose of the utility model is to provide a central venous puncture fixer, which can solve the problems of increased puncture difficulty, increased complications, and even fatal complications due to the patient's own change of body position during central venous puncture.

In order to solve the above-mentioned technical problems, the technical scheme of the utility model is as follows: a central venous puncture fixer, which is characterized in that: it includes a head and neck fixing frame, a shoulder and back fixing frame, and the head and neck fixing frame includes a horizontal support frame and a vertical support frame. The horizontal support frame is an arc-shaped plate with two ends upturned. The two ends of the horizontal support frame are provided with fixing holes, and the fixing holes are provided with fixing belts. The horizontal support frame and the vertical support frame are connected in a "T" shape; The shoulder and back fixing frame includes a horizontal support frame, and a vertical support frame is arranged on one side of the horizontal support frame. The vertical support frames are respectively arranged at the two ends and the middle part of the horizontal support frame. Correspondingly, fixing holes are arranged on the vertical supporting frame at both ends of the horizontal supporting frame, a fixing belt is arranged in the fixing hole, and a connecting sleeve is provided on the other side of the horizontal supporting frame; the vertical support of the head and neck fixing frame The supporting frame is plugged into the connecting sleeve.

Improvement to the above technical solution: the head and neck fixing frame is covered with a cushion.

A further improvement to the above technical solution: the shoulder and back fixing frame is provided with a cushion on the vertical support frame in the middle of the horizontal support frame, and the thickness of the cushion is 4-6 cm.

A further improvement to the above technical solution: the connecting sleeve is a hollow steel pipe, the side of the steel pipe is provided with screw holes, and fastening bolts are provided in the screw holes.

Beneficial effect:

Using the central vein puncture fixer described in the utility model, the predetermined fixed position in the patient's central vein can be maintained through the head and neck fixing frame and the shoulder and back fixing frame, so as to improve the success rate of puncture and reduce the occurrence of puncture complications; The fixed frame is covered with a soft pad, which can reduce the discomfort of the patient's head; the vertical support frame located in the middle of the horizontal support frame is provided with a soft pad, the thickness of which is 4-6 cm, and is used to maintain the patient's shoulder lift. The vertical head position is conducive to vein expansion and improves the success rate of puncture; the connecting sleeve is a hollow steel pipe, and the side of the steel pipe is provided with screw holes, and fastening bolts are arranged in the screw holes, so that the vertical support frame of the head and neck fixed frame The insertion depth can be adjusted, which is suitable for patients with different body sizes. The angle between the head and neck fixing frame and the shoulder and back fixing frame can be freely selected. After the angle is selected, the head and neck fixing frame and the shoulder and back fixing frame The relative position between them is fixed.
