Abstract
A continuous injecting apparatus comprises an hollow housing (10) including an upper portion and a lower portion (10′,10″); a syringe (1) mounted in the hollow housing (10); a connector (20) tightly threaded onto the front end portion of the housing (10); an adjusting portion (90) including an adaptor (50) coupled to the rear end of the hollow housing (10); a plug (60) inserted into the adaptor (50); a plunger (70) including a gripper (74) coupled at the front end to the pushing portion (3b) of the syringe (1), a grasping portion (76) formed to force a user to push down the piston (3) of the syringe (1) and a stopper (80) movably mounted onto a rod of the plunger (70), thereby adjusting an amount of medical liquid to be injected for diagnostic or therapeutic purposes.
Claims26
A continuous injecting apparatus comprising:
- a housing having upper and lower portions, the upper and lower portions configured to be separated and adapted to receive a disposable syringe having a piston and a piston rod;
- a connector configured to connect the upper and lower portions of the housing;
- and
- a pushing assembly coupled to a rear end of the housing and configured to transfer input force to the piston of the disposable syringe, wherein front portions of the upper and lower portions are threadedly engaged with a threaded portion of a clamp.
A continuous injecting apparatus with a disposable syringe comprising:
- a hollow housing including:
- a connector coupled to a front portion of the syringe to supply liquid to be injected to the disposal syringe including a syringe rod and a pushing portion, and a clamp coupled to a needle fitting portion of the syringe to allow a needle to be communicated with the syringe positioned therein, wherein the connector and the clamp are assembled in order to form an injection portion;
- and
- an adjusting portion including:
- an adaptor coupled to a rear end of the hollow housing, which covers the moving distance of the syringe rod, a plug fitted into the adaptor to guide the longitudinal movement of the syringe rod, a plunger coupled to a front end of the pushing portion to operate the syringe and a stopper movably mounted onto a rod of the plunger to adjust an amount of the liquid to be injected, the adaptor, wherein the plug and the plunger are assembled in order to form an operating portion.
A continuous injecting apparatus comprising:
- a housing having upper and lower portions, the upper and lower portions configured to be separated and adapted to receive a disposable syringe having a piston and a piston rod;
- a connector configured to connect the upper and lower portions of the housing;
- and
- a pushing assembly coupled to a rear end of the housing and configured to transfer input force to the piston of the disposable syringe, the pushing assembly comprising:
- an adaptor coupled to a rear end of the housing;
- a plug inserted onto the adaptor and including a flange formed to mate with a portion of the adaptor;
- and
- a plunger including (1) a gripper adapted to couple to a rear end of the piston rod of the syringe, (2) a grasping portion configured to transfer input force to the piston rod of the syringe and (3) a stopper movably mounted onto a rod of the plunger so as to adjust an amount of fluid to be injected.
