WEIGHT DEPENDENT, AUTOMATIC FILLING DOSAGE SYSTEM AND METHOD OF USING SAME

摘要

A weight dependent, automatic filling dosage system (10) including a pump (18), controlled by a minicomputer (16), in fluid communication with a fluid reservoir (22). A connecting tube (24) provides fluid communication between the pump (18) and a syringe assembly (20). The syringe assembly (20) includes a gun body (54) having a handle assembly (58) and a barrel (52) for receiving fluid. A fluid inlet passes through the plunger assembly (70). The handle assembly (58) is connected to a shaft (60) attached to the plunger assembly (70). The system (10) includes devices for weighing (14) and restraining (12) the subject. The method of medicating subjects with varying doses of various substances includes the steps of weighing the subject and sending a weight signal to the computer (16). The computer (16) calculates the required dosage to be administered to the subject according to its weight. A dosage signal is sent to the pump (18) to fill the syringe (20) with the proper dosage. Once filled, the dosage is administered to the subject.
