A dosing syringe comprising a barrel and a piston is provided. The piston is slidably receivable in the barrel and can move within the barrel from a maximum inserted position to a withdrawn position to draw a dose of a product into the barrel. The syringe comprises means for pre-setting the withdrawn position, which defines a maximum dose which can be drawn into the barrel.

A protected sterile injector with ready isotonic sodium chloride which provides drug dilution and administration in patient treatment services, contains isotonic sodium chloride liquid, includes at least one chamber having a hole for the medicament outlet, a piston connected to the chamber, ajutage that is located on the upper part of the chamber hole, and which is the part that allows for attachable-detachable use and is suitable for the use of different needle tips, a gasket which is connected to the upper part of the piston in the chamber, separating the liquid in the chamber and the empty space, at least one needle tip located in the outermost part of the chamber, a clamp connected to the outer part of the piston that prevents the involuntary outflow of the liquid in the chamber by preventing the movement of the piston and ensuring the controlled use of the liquid.

An injector device comprising: an outer housing for receiving a medicament container; and a drive mechanism for dispensing medicament from a medicament container received in the outer housing. The drive mechanism comprises a plunger rod and a displacing member configured to displace a distal end of the plunger rod into said medicament container to dispense said medicament. The device further comprises a brake configured to slow the rate of displacement of the plunger rod under the force of the displacing member.

An antiseptic medical cap that may include a base, a sidewall, and a chamber configured to receive a proximal end of a medical fluid port having an opening. The antiseptic medical cap, in some instances, may include an insert having a gas-releasing anti-microbial compound and/or include a nitric oxide-releasing system that is configured to be positioned at least partially through the opening of the medical fluid port when the antiseptic medical cap receives the proximal end of the medical fluid port into the chamber.

Disclosed are systems that include a syringe having a barrel configured to hold a fluid and a plunger configured to draw the fluid into the barrel when the plunger is pulled backward through the barrel. The syringe is configured to inhibit forward movement of the plunger. For example, the systems can include mating pockets configured to engage barbs to inhibit forward movement of the plunger.

A syringe assembly including: (1) a syringe barrel defining a chamber; (2) a plunger mounted in the chamber and moveable with respect to the barrel; and (3) a cap holder assembly containing a cap and an absorbent material removably attached to the syringe.

An injector comprises a cylindrical barrel, a movable body housed in the barrel, and a plunger coming into separable contact with the movable body. The movable body includes a main body having an outer diameter smaller than an inner diameter of the barrel, a disk-shaped seal body disposed on the main body and including an outer circumferential end brought into close contact with an inner circumferential surface of the barrel, and at least one projecting portion projecting from the main body toward the inner circumferential surface of the barrel. A distance from a central axis of the movable body to a leading end of the at least one projecting portion is smaller than a half of an outer diameter of the seal body.

Embodiments including an injection device having a housing with an outer surface, an inner surface, a proximal end and a distal end, and a defining a chamber extending between the proximal end and the distal end are provided herein. The device may include a plunger having a first end and a second end, the plunger being movable proximally and distally within the chamber of the housing, the plunger comprising a plunger rod extending from the first end to the second end of the plunger; and a plunger limiting mechanism configured to interface with the plunger rod, to limit the proximal movement of the plunger and prevent removal of the plunger from the housing.

A syringe includes a barrel, a plunger, and a sealing member creating a seal between the plunger and the barrel. The barrel includes a first portion with a first inner diameter and a second portion with a second inner diameter that is larger than the first inner diameter. The sealing member engages the first portion of the barrel to give rise to a first contact pressure when the barrel is filled with product. The first contact pressure is sufficient to maintain a gas-tight seal over the expected temperature ranges −25° C. to 40° C. A first force is applied to the plunger to overcome the first contact pressure and move the plunger out of the first portion and into the second portion to dispense product. The sealing member engages the second portion of the barrel to give rise to a second contact pressure that is lower than the first contact pressure. A second force lower than the first force is sufficient to overcome the second contact pressure and move the plunger in the second portion to continue dispensing product. The syringe may include a restraining element for accommodating expansion of the product during freezing.

Devices used to deflate an inflatable hemostasis device are disclosed. The devices may be configured to deflate the inflatable hemostasis device in staged increments over a period of time. The devices may include a barrel member and a plunger member comprising an insert configured to couple with a retention ring of the barrel to restrict a retraction distance of the plunger member.
