Abstract

A fluid dispensing device, particularly suited to medicine but also having many other applications. The device selectively dispenses any of one or more fluids contained within the device. Adapters on the dispensing end of the unit permit the device to be effectively used for intra-venous, intra-dermal or intra-muscular injections, gasses, colloids, gels, liquids or other fluids. Adapters on the head of the unit permit the device to be used with or without electrical power and to varying degrees of automatic control for timing, sequence, volume of fluid dispensed and other features.

Claims

1. A fluid dispensing device comprising:

a. a head assembly comprising a means to select a fluid to be dispensed and a means to dispense a fluid; and

b. a case assembly that contains a fluid, or fluids, to be dispensed; and

c. an apical assembly that funnels the fluids to be dispensed through a common output.

2. A fluid dispensing device as in claim 1 where said means to dispense a fluid is powered by a spring.

3. A fluid dispensing device as in claim 1 where said means to dispense a fluid is pneumatically powered.

4. A fluid dispensing device as in claim 1 where said means to dispense a fluid is an electronic lineal actuator.

5. A fluid dispensing device as in claim 1 where the fluid dispensation is computer controlled.

6. A fluid dispensing device as in claim 1 where said apical assembly has a port for an external fluid source to flush said apical assembly.

7. A fluid dispensing device as in claim 1 where said apical assembly has a common output that prevents the commingling of fluids dispensed.

8. A fluid dispensing device as in claim 1 that has a mechanical means to set the volume of fluid to be dispensed.

9. A fluid dispensing device as in claim 1 where said head assembly, said case assembly and said apical assembly are separable.

10. A fluid dispensing device according to claim 1 further comprising a cartridge assembly of pre-selected fluids that is removable from said case assembly.

11. A method of using the fluid dispensing device as in claim 1 where the fluids dispensed are drugs.

12. A method of using the fluid dispensing device as in claim 1 where the fluids dispensed are lubricants, food products, gasses, liquids, chemical reagents, tints, colorants, stains, paints or gels.

13. A fluid dispensing device that contains one or more fluids that can be selectively dispensed through a common output.

14. A fluid dispensing device as in claim 13 that further comprises a replaceable cartridge of a predetermined fluid, or fluids, to be dispensed.

15. A fluid dispensing device as in claim 13 that further comprises a port for an external fluid source to flush said common output.

16. A method of using the fluid dispensing device as in claim 13 where the fluids dispensed are drugs.

17. A method of using the fluid dispensing device as in claim 13 where the fluids dispensed are lubricants, food products, gasses, liquids, chemical reagents, tints, colorants, stains, paints or gels.

18. A fluid dispensing device comprising a case that contains fluid, or fluids, a means to select a fluid to be dispensed and a means to dispense a fluid through a common output.

19. A Fluid dispensing device as in claim 18 that further comprises a replaceable cartridge containing a predetermined fluid, or fluids, to be dispensed.

20. A method of using the fluid dispensing device as in claim 18 where the fluids dispensed are drugs, lubricants, food products, gasses, liquids, chemical reagents, tints, colorants, stains, paints or gels.
