safety needle

Abstract

The invention discloses a safe remaining needle, which comprises a catheter seat and a needle seat, wherein an acupuncture prevention protection assembly is arranged between the catheter seat and the needle seat and comprises a protection sheet and a protection seat, the two ends of the protection seat are respectively provided with a first through hole and a second through hole, the protection sheet consists of a connecting sheet and baffle sheets arranged at the two ends of the connecting sheet, a needle passing hole is formed in the first baffle sheet far away from the catheter seat, an opening is formed in a connecting part of the connecting sheet and the second baffle sheet near the catheter seat, a deformation point is arranged at the head part of a puncture needle, the outer diameter of the deformation point is smaller than the inner diameter of the first through hole and is greater than the inner diameter of the needle passing hole or the second through hole, the distance from the deformation point to the needle point of the puncture needle is smaller than the distance from the needle passing hole formed in the first baffle sheet to the second baffle sheet, the first baffle sheet is fixedly connected with the protection seat, the connecting sheet consists of a deformation section connected onto the second baffle sheet and a recovery section connected onto the first baffle sheet, and a groove where the deformation section is located is an inclined groove. The safe remaining needle has the advantage that harm such as acupuncture injury, disease infection and environment pollution can be effectively prevented.

Description

technical field [0001] The invention belongs to the field of infusion equipment, in particular to a disposable safe indwelling needle with anti-acupuncture effect. Background technique [0002] The use of intravenous indwelling needles can reduce the pain caused by repeated venipuncture and the fear of injections in children, relieve the anxiety of parents, facilitate clinical medication, rescue medication for acute and critical patients, reduce the workload of nurses, and reduce the number of patients. Pain in children, so intravenous indwelling needles are widely used in clinical practice. However, the existing indwelling needles are withdrawn after use, and the needles are contaminated by the blood of the patient. When medical staff pull out or clean and discard the indwelling needles, they are easily stabbed by the needles and easily infected with diseases. At the same time, the discarded needles are exposed to the environment. It is easy to cause environmental pollutio...

Problems solved by technology

However, the existing indwelling needles are withdrawn after use, and the needles are contaminated by the blood of the patient. When medical staff pull out or clean and discard the indwelling needles, they are easily stabbed by the needles and easily infected with diseases. At the same time, the discarded needles are exposed to the environment. It is easy to cause environmental pollution and has serious safety hazards

Chinese patent application 2013100333325 discloses a disposable safe indwelling needle. This patent solves the disadvantages caused by the exposed environment of the needle through the anti-acupuncture component, but the protective sheet in the anti-acupuncture component is back in the protective seat. The elasticity is not enough, and the structure of the protective sheet is relatively complicated, and the production cost is high
