To this end, the present invention provides a PICC medical puncture instrument fixing mechanism.

SUMMARY OF THE INVENTION

In order to make up for the deficiencies of the prior art, at least one technical problem proposed in the background art is solved.

The technical solution adopted by the present invention to solve the technical problem is as follows: a PICC medical puncture instrument fixing mechanism according to the present invention includes a bottom plate; C-shaped elastic pieces are fixed on both sides of the bottom plate; the C-shaped elastic pieces are close to the bottom plate. A connecting tape is fixed on the surface; an isolation pad is arranged between the C-shaped elastic pieces; a first Velcro is fixed on the bottom surface of the isolation pad, and a second Velcro is fixed on the top surface; the top of the isolation pad is provided with a fixed The end of the connecting belt is fixed with a corresponding first Velcro; the bottom surface of the fixing pad is fixed with a corresponding second Velcro; the PICC puncture instrument is fixed on the patient for a long time, and the patient may rest at night. It will squeeze the puncture instrument, which will cause the puncture instrument to fall off, and then need to be punctured again, which will bring unnecessary pain to the patient. By placing the arm on the bottom plate, two C-shaped shrapnel clamp both sides of the arm to achieve a fixed effect, and the isolation pad Cover under the puncture device, separate the puncture device from the arm, reduce the pressure of the puncture device pressing on the skin surface for a long time, connect the isolation pad with the connecting belt through the first Velcro, the fixing pad covers the puncture device, and pass the second The Velcro connects the fixing pad and the isolation pad, and fixes the puncture device between the isolation pad and the fixing pad. The end of the C-shaped shrapnel will protect the fixing pad. When the patient's arm is punctured, the edge of the fixing pad will It will not be scratched, thereby reducing the situation that the puncture instrument is touched and then falls off.

Further, a support plate is fixed on the top of the C-shaped elastic piece; a chute is provided on the side of the support plate; a baffle is arranged in the chute, and the baffle is located between the two C-shaped elastic pieces; the baffle is close to the The side of the chute is provided with a plurality of limit holes; the support plate is provided with a connecting hole at the position corresponding to the limit hole; a connecting pin is slidably connected in the connecting hole; when the patient sleeps at night, it may be pressed to the The arm of the puncture instrument causes the puncture instrument to fall off, the baffle passes through the chute, and the baffle is fixed on the support plate by the connecting pin, so that the puncture instrument can be more stable when it is subjected to external pressure, and the baffle can also prevent foreign objects from hitting the fixing pad , causing the puncture instrument to loosen or even fall off.
