We provide a system for continuously injecting liquids. [Solution] The system includes a syringe body defining a proximal opening and a distal needle interface; a proximal stopper member and a distal stopper member forming a proximal and distal chamber; a first liquid in the distal chamber and a second liquid in the proximal chamber; a plunger configured to be manually operated to insert the proximal stopper member distally; and a needle hub assembly coupled to the syringe body, the needle assembly including a needle. The needle has an internal structure and defines a distal opening, an intermediate opening, and a proximal opening, which are fluid-coupled through the internal structure of the needle. By operating the plunger member to insert the proximal stopper member, the first liquid is first discharged from the distal chamber, and then, continuously, the second liquid is discharged from the proximal chamber.

A safety syringe system that automatically shields a needle after an injection. A plunger extends into a barrel. An elastic return construct is provided that has at least one stretchable arm. The elastic return construct engages the barrel and positions each stretchable arm along the exterior of the barrel. A safety shield is provided that slides over a first end of the barrel. In a first position, the needle is protected by the safety shield. In a second position, the needle is exposed. The safety shield engages and stretches the elastic return construct when moved from the first position to the second position. A locking mechanism is used to lock the safety shield into its second position. The locking mechanism is released by elements displaced by movement of the plunger.

To provide a suitable system and method for safety syringes. [Solution] One embodiment relates to a system for injection, the system comprising: a syringe body defining an internal drug chamber; a stopper member configured to be inserted into the internal drug chamber to contain a drug within the drug chamber; a plunger member configured to be manually operated to insert the stopper member into the syringe body; and a needle having a proximal and distal end, wherein the proximal end has an anchor geometry configured to be at least partially inserted into the stopper member, thereby pulling the needle proximal together with the stopper when the stopper member is retracted, thereby at least partially containing it within the internal drug chamber.

A safety syringe comprising a barrel having an opening at an end thereof and a bung positioned in the barrel and creating a volume between the opening and the bung. The safety syringe also comprises a handle portion secured to the barrel and a syringe plunger slidably engaged with the handle portion and moveable within the barrel on an inward stroke to drive the bung forwards within the barrel to cause a substance within the volume to be expelled from the opening. The safety syringe further comprises a rotation mechanism configured to rotate the syringe plunger within the barrel at a point during the inward stroke when the syringe plunger is in contact with the bung, such that a rotational force is applied to the barrel and a brake connected to the handle portion and configured to provide a frictional force to resist the rotational force applied to the barrel.

A safety lock syringe assembly comprising a barrel including a distal end and a proximal end, one or more lugs extending outwardly from an outer surface of the barrel, and a needle extending from the distal end, and a sleeve having threads that engage the one or more lugs, the sleeve includes a sleeve locking mechanism, wherein the sleeve threadably rotates in a first direction to a first position that exposes the needle, the sleeve threadably rotates in a second direction to a second position that shields the needle, and the sleeve threadably rotates in the second direction to a third position that engages the one or more lugs to the sleeve locking mechanism to irreversibly lock the shield to the barrel.

Safety syringe assemblies are described. A safety syringe assembly comprises a syringe barrel, a needle hub having a proximal end configured to be connected to the syringe tip and a distal end having an opening configured to receive a needle cannula, a needle plug comprising a distal end comprising a socket and a proximal end comprising a plunger connection element configured to engage a needle plug engagement element on the distal face of the plunger rod. The needle plug and the needle cannula are retractable inside the syringe tip or the needle hub.

A system for serially injecting liquids includes a syringe body defining a syringe proximal opening and a distal needle interface, proximal and distal stopper members, forming proximal and distal chambers. The system also includes a first liquid in the distal chamber and a second liquid in the proximal chamber, and a plunger configured to be manually manipulated to insert the proximal stopper member distally. Moreover, the system includes a needle hub assembly coupled to the syringe body, the needle assembly including a needle. The needle defines a needle interior, and distal, middle and proximal openings. The distal, middle and proximal openings are fluidly coupled through the needle interior. Manipulating the plunger member to insert the proximal stopper member initially expels the first liquid from the distal chamber, then serially expels the second liquid from the proximal chamber.

The application relates to the technical field of medical equipment, and discloses a disposable syringe capable of preventing injury, which comprises a needle cylinder, a needle head is connected to the upper end of the needle cylinder, a rubber plug is movably sleeved in the needle cylinder, and a top rod is fixedly connected to the bottom of the rubber plug. Through the arrangement of the straight rod, the air cavity and the high-pressure gas chamber, the air in the air cavity is extruded into the cavity along with the pushing of the plunger by the ejector pin, so that the tail end sharp head of the straight rod pierces the high-pressure-resistant film, the high-pressure inert gas in the high-pressure gas chamber enters the cavity, the high-pressure gas can push the straight rod to move to the end of the needle head, and the straight rod enters the needle tube along the needle head and extends out of the needle tube. Since the rubber plug segment cut off firstly extends out of the needle tube, people will not be injured by the sharp end of the needle head when handling or destroying the contact needle head, the harm caused by the needle head injury can be avoided, even infection, and the needle head can be completely avoided from being reused.
