Description

An infusion needle with a protective sleeve

technical field

The utility model relates to the technical field of medical appliances, in particular to an infusion needle with a protective sleeve.

Background technique

At present, human infusion has been widely used as an important and effective medical means to treat diseases. The needle must be secured during infusion. When the medical staff tie the needle of the infusion needle to the intended site of the recipient, they must fix the needle handle by hand, and then stick the tape to fix the needle handle. During the operation, the medical staff may shake their hands. It is not easy to locate and easily affects the accuracy of needle fixation; in addition, during the infusion process, the patient's movement will also affect the needle fixation, the needle is displaced, which leads to the need to re-puncture the infusion needle, which not only increases the workload of medical staff, but also increases patient's pain.

Infusion needles are disposable medical supplies. In order to prevent the spread of diseases through blood, the infusion needles are discarded and disposed of after use. At present, after the infusion needle is separated from the human body, a plastic protective cover is placed on the needle head of the infusion needle to prevent stabbing medical personnel and medical waste disposal personnel. To prevent the infection of diseases caused by stabbed medical personnel and garbage disposal personnel, and it is extremely easy to stab medical personnel, we provide an infusion needle with a protective cover.
