Weight dependent, automatic filling dosage system and method of using same

Abstract

A weight dependent, automatic filling dosage system including a pump, controlled by a minicomputer, in fluid communication with a fluid reservoir. A connecting tube provides fluid communication between the pump and a syringe assembly. The syringe assembly includes a gun body having a handle assembly and a barrel for receiving fluid. A fluid inlet passes through the plunger assembly. The handle assembly is connected to a shaft attached to the plunger assembly. The system includes devices for weighing and restraining 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. The computer calculates the required dosage to be administered to the subject according to its weight. A dosage signal is sent to the pump to fill the syringe with the proper dosage. Once filled, the dosage is administered to the subject.

 a minicomputer;    a fluid reservoir;    a pump in fluid communication with said fluid reservoir, said pump controlled by said minicomputer;    a syringe assembly; and    a connecting tube providing fluid communication between said pump and said syringe assembly.    
     
     
         2 . The system of  claim 1 , further comprising a weighing device for weighing a subject.  
     
     
         3 . The system of  claim 2 , further comprising a restraining device for restraining the subject.  
     
     
         4 . The system of  claim 1 , further comprising means for inputting data relating to a subject's weight in said minicomputer.  
     
     
         5 . The system of  claim 4 , further comprising a central computer for maintaining the health history of various subjects, said central computer communicating with said minicomputer.  
     
     
         6 . The system of  claim 1 , wherein said pump is a valveless, viscosity-independent pump.  
     
     
         7 . The system of  claim 1 , further comprising an automatic sensoring device for monitoring the fluid level in said fluid reservoir.  
     
     
         8 . The system of  claim 1 , further comprising a container receptacle connected to said fluid reservoir, said container receptacle adapted to receive a fluid container containing fluid for delivery to said fluid reservoir.  
     
     
         9 . The system of claim of  claim 5 , wherein said pump is a valveless, viscosity-independent pump.  
     
     
         10 . A method of medicating subjects with varying doses of various substances, comprising the steps of: 
 weighing the subject;    sending a weight signal to a computer;    the computer calculating the required dosage to be administered to the subject according to the subject's weight;    sending a dosage signal to a pump to fill a syringe with the proper dosage; and    administering the proper dosage to the subject.    
     
     
         11 . The method of  claim 10 , wherein the required dosage is administered in individual dosages of no more than 10 cc maximum aliquots.  
     
     
         12 . The method of  claim 10 , further comprising the steps of: 
 identifying the subject; and    inputting the subject's identification in the computer.    
     
     
         13 . The method of  claim 12 , wherein the step of identifying the subject is done by using a scanner.  
     
     
         14 . The method of  claim 10 , wherein the step of sending a weight signal to the computer is done electronically.  
     
     
         15 . A syringe apparatus comprising: 
 a gun body having a handle assembly;    a barrel for receiving fluid, the barrel attached to the gun body;    a fluid inlet passing through the plunger assembly; and    the handle assembly connected to a shaft attached to the plunger assembly.    
     
     
         16 . The syringe apparatus of  claim 15 , wherein the plunger assembly has an inner plunger assembly and an outer plunger assembly, the inner plunger assembly permitted to move relative to the outer plunger assembly.  
     
     
         17 . The syringe apparatus of  claim 16 , wherein the fluid inlet passes through the inner plunger assembly.  
     
     
         18 . The syringe apparatus of  claim 17 , wherein the inner plunger assembly includes retrieval ports for retrieving the fluid from the barrel.  
     
     
         19 . The syringe apparatus of  claim 17 , further comprising a discharge outlet in the barrel having a spring-loaded valve.
