Device with needling prevention function

Abstract

The invention belongs to the field of medical instruments and particularly relates to a device with a needling preventing function. The device comprises a steel needle and a catheter seat, and an expansion protruding part is arranged on the upper portion of a steel needle tube body. A clamping piece seat is installed at the rear end of the catheter seat, openings are formed in the upper end and the lower end of the clamping piece seat, and an elastic clamping piece in an opening state is installed in the clamping piece seat. The elastic clamping piece is formed by connecting a bent hook at the front end, an elastic arm in the middle and a steel needle limiting seat at the rear end. The bent hook is composed of a hook part and a check piece, a notch corresponding to the hook part is formed in the rear end of the catheter seat, the lower portion of the steel needle tube body sequentially penetrates through the opening in the upper end of the clamping piece seat, the steel needle limiting seat and the opening in the lower end of the clamping piece seat from top to bottom, and the expansion protruding part of the steel needle is located above the steel needle limiting seat all the time. The hook part of the bent hook of the elastic clamping piece in the opening state is hooked in the notch, and the end, opposite to the hook part, of the check piece abuts against the steel needle tube body. By means of the device, medical staff can be prevented from being punctured, and meanwhile the medical staff can be prevented from making contact with blood flowing out of the needle tip of the steel needle.
