摘要：
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.
