Abstract
A syringe system (100) is provided. The syringe system comprises a pump assembly (101) including a movable actuation rod (440) and a plunger contact (445) coupled to an end of the movable actuation rod (440). The syringe system also comprises a cartridge assembly (102). The cartridge assembly (102) includes a manifold (105) removably coupled to the pump assembly (101) and a syringe cartridge (107) positioned within the manifold (105) and including a plunger assembly (330) movable with respect to the manifold (105) upon actuation of the actuation rod (440).
Claims28
A syringe system (100), comprising:
- a pump assembly (101) including a movable actuation rod (440) and a plunger contact (445) coupled to an end of the movable actuation rod (440);
- a cartridge assembly (102) including:
- a manifold (105) removably coupled to the pump assembly (101);
- and
- a syringe cartridge (107) positioned within the manifold (105) and including a plunger assembly (330) movable with respect to the manifold (105) upon actuation of the actuation rod (440).
A cartridge assembly (102) for a syringe system (100), comprising:
- a manifold (105) including one or more fluid ports (106);
- a syringe housing (210) positioned within the manifold (105);
- a fluid barrel (211) positioned within the syringe housing (210) and in fluid communication with the one or more fluid ports (106);
- and
- a plunger assembly (330) movable within the fluid barrel (211) to draw fluid into and expel fluid out of the fluid barrel (211).
A method for forming a syringe system, comprising steps of:
- positioning a movable actuation rod and a plunger contact within a pump assembly;
- positioning a syringe cartridge within a manifold, the syringe cartridge comprising a plunger assembly movable with respect to the manifold;
- and
- removably coupling the manifold to the pump assembly such that actuation of the actuation rod moves the plunger assembly.
