Abstract

The invention discloses a disposable painless syringe, and belongs to the technical field of medical instruments, the disposable painless syringe comprises an upper shell, a lower shell, a disposable painless syringe body, a limiting cylinder, a connecting rod, a pressing key, a limiting mechanism and a reset mechanism, the upper shell and the lower shell are fixedly connected through threads, the disposable painless syringe body is inserted into the upper shell and the lower shell, and the limiting cylinder is fixedly connected with the connecting rod. The limiting cylinder is arranged above the disposable painless syringe body, the pressing key, the limiting mechanism and the limiting cylinder are connected into a whole through the connecting rod, the reset mechanism is arranged on the side wall of the upper shell, a first spring is further arranged in the bottom end of the lower shell, and the first spring is arranged at the bottom of the disposable painless syringe body. The syringe needle can be stretched out and drawn back, medical staff are protected against needling threats after injection is completed, the risk of cross infection between the medical staff and a patient due to needling injury is effectively reduced, and the personal safety of the medical staff is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a disposable painless syringe. Background technique [0002] It has been confirmed that 20 kinds of pathogens can be transmitted by needlestick inoculation; when needlestick injury occurs, generally only 0.004mL of blood is enough to infect the injured person with hepatitis B virus, which will cause serious consequences and long-lasting damage to the injured person. Psychological stress seriously affects their normal life. [0003] At present, in clinical work, nurses often come into contact with needles, knives, scissors, and patients' blood, body fluids, secretions, etc., which make nurses often exposed to occupational risk factors, especially needle stick injuries. A needlestick injury is an accidental injury deep enough into the skin to cause the injured person to bleed, so that blood or bodily fluids contaminated with pathogens inoculate the victim. Needle stick in...
