Abstract: Vented syringes are described herein. A vented syringe includes a syringe body and a plunger body. The syringe body defines a syringe cavity. The plunger body is at least partially disposed within the syringe cavity. The plunger body includes an air intake channel defined within the plunger body. The vented syringe further includes a plunger seal that is sealingly engaged with the syringe cavity to cooperatively define a syringe volume. The vented syringe further includes a one-way valve in fluid communication with the air intake channel and the syringe volume, wherein the one-way valve is configured to prevent fluid flow from the syringe volume to the air intake channel and permit fluid flow from the air intake channel to the syringe volume.

Abstract: Syringes are described herein. In certain embodiments, a syringe includes a syringe body, a movable plunger, and a biasing member. The syringe body defines a cavity and a port in fluid communication with the cavity. The movable plunger is disposed within the cavity. The plunger and cavity define a volume. The port is in fluid communication with the volume. The biasing member is coupled to the plunger. The biasing member is configured to urge the plunger toward the port to dispense a fluid stored within the volume at a desired rate.

Abstract: IV spikes are described herein. An IV spike includes a spike body. The spike body can be formed of a first material and can include a spike portion converging to a point. The IV spike further includes at least one spike flow port formed through the spike body. The IV spike further includes a lower flow port in fluid communication with the at least one spike flow port. The IV spike can also include an overmolded engagement feature disposed around the spike body, wherein the overmolded engagement feature comprises a second material and is configured to retain the IV spike within an IV container.
