Description

Rotary anti-acupuncture syringe

Technical Field

The invention relates to the technical field of medical instruments, in particular to a rotary type anti-acupuncture syringe.

Background

The syringe is a common medical appliance, and the liquid medicine is directly injected into a human body through the syringe, so that the injection end of the syringe is protected by a protective sleeve to ensure sterility and safety. In order to prevent the syringe needle from accidentally injuring a user after use to cause medicine pollution or prevent the syringe from being used for the second time, the needle is generally required to be uniformly recovered after injection is finished at present; however, with the further strict management of medical devices, some mechanisms have required that a special protection device is additionally arranged on the disposable syringe, and after the injection is completed, the protection device is started to protect the needle head part, so that the needle head is prevented from being accidentally injured, the needle head is also prevented from being separated from the syringe body, and the use safety of the disposable syringe is improved.

Through the magnanimity retrieval, discover that prior art publication number is CN211751555U, disclose a syringe protective sheath, relate to protective sheath technical field, including outer protective sheath, the inside one side of outer protective sheath is provided with interior protective sheath, the inside one side of outer protective sheath is provided with first arch, first bellied one side is provided with the second arch, one side of interior protective sheath is provided with first bulge loop, one side that first bulge loop was kept away from to interior protective sheath is provided with the second bulge loop. The syringe is protected by the inner protective sleeve and the outer protective sleeve, so that the syringe is prevented from being broken or broken, loss is avoided particularly when scarce materials and precious medicines are placed in the syringe, and cost is reduced.

To sum up, the mode that the relative position of protective sheath and syringe needle was locked through bulge loop and arch to current syringe, in the actual operation in-process, the effect of locking is relatively poor for bulge loop and bellied locking mode, if the operating force is too big or the undersize all can destroy the locking effect.
