The utility model discloses a kind of pre-filled syringe protective caps, belong to medical instrument technical field, including the protective cap body, needle tip cavity, conical cavity, sliding cavity and connecting cavity are sequentially arranged in its inside along the axial direction. The sliding cavity side wall is provided with exhaust hole, the inside sliding is provided with silica gel block extending to connecting cavity, and connecting cavity diameter is greater than sliding cavity diameter. When syringe is inserted, realize phased exhaust function: initial stage is discharged compressed air by exhaust hole, final stage silica gel block slidingly closes exhaust hole, to avoid external pollution. While optimizing needle support stability, the utility model solves the problem of falling caused by poor exhaust of traditional protective cap, while taking into account aseptic seal and operation reliability, suitable for high health requirements injection scene such as vaccine, biological preparation.

A cartridge and loading system for loading tamper-evident syringe caps into a robotic pharmaceutical compounding device. The compounding device has a syringe finishing station, and can transfer tamper-evident caps from the cartridge to the syringe finishing station. The cartridge has a floor disposed at an angle to horizontal. The device may include a vibratory element for vibrating the cartridge, so that tamper-evident caps are fed to an outlet of the cartridge by gravity.

The utility model relates to the technical field of medical instruments, in particular to an injector cover pulling box. An injector cover pulling box comprises an injector and the like, a shell is fixedly connected to the top of a bottom plate, a pushing assembly is arranged at the top of the shell, the injector is placed on the pushing assembly, a needle cover is arranged at the bottom of the injector, a clamping mechanism used for clamping the needle cover is arranged in the shell, and the pushing assembly is used for pushing the clamping mechanism to complete the clamping action. The syringe needle cover can be rapidly separated through one-hand operation, operation is easy, convenient and efficient, the working efficiency of medical workers is remarkably improved, meanwhile, the risk that the medical workers are punctured when manually removing the needle cover is effectively reduced in the process, use safety is enhanced, in addition, stable clamping and releasing of the needle cover are guaranteed through the design of a rubber roller, a ratchet wheel and a pawl, and the safety of the medical workers is improved. And the reliability and the practicability of the whole operation are improved.

This drug cartridge is used by being incorporated into a drug injection device, and is provided with: a syringe that accommodates a drug; a housing that accommodates the syringe in a state in which the syringe is movable in the front-rear direction; a cover attached to a front end portion of the housing; and a spring that is provided between the syringe and the housing and constantly biases the syringe rearward.

[Problem] To provide a syringe cap having two functions, namely: slippage stopping when removing the same from the tip of a syringe; and excessive push-in prevention when attaching the same to the tip of the syringe. [Solution] A syringe cap is characterized by having a substantially cylindrical outside shape and having, on the lateral surface, a plurality of continuous protrusions that have a waveform cross-sectional shape and that are provided in the axial direction. The protrusions each have: a first inclined plane that has a first inclination and that extends from a first minimum diameter part to a maximum diameter part; and a second inclined plane that has a second inclination and that extends from the maximum diameter part to a second minimum diameter part. The first inclined plane has a gradient having a constant magnitude at a portion excluding at least the first minimum diameter part and the maximum diameter part. The maximum diameter part is located at a position closer to an opening as compared with a position 1 / 2 of the full length of the corresponding one of the protrusions.
