Abstract

A hypodermic fluid dispenser and a collapsible body for the hypodermic fluid, with a hypodermic needle injecting the fluid once sufficient pressure is applied to collapse the body. There is also disclosed an electrical hypodermic fluid dispenser having a reusable, rechargeable power source, and a reservoir from which hypodermic fluid can be withdrawn for injection through a single injection orifice.

Claims

1. A hypodermic fluid dispenser for dispensing fluid from container means, said dispenser comprising:

fluid withdrawal means for withdrawing fluid from the fluid container means;

electrically-operated injection means for injecting fluid withdrawn from the container means into a body;

rechargeable power source means for supplying electrical power to said injection means, said power source means being depletable as its electrical power is transferred, said power source means being removable from said dispenser for subsequent recharging; and

power source operating means for operationally connecting said power source means to said injection means, said power source operating means making operational a power source means replacing a removed power source means.

2. A hypodermic fluid dispenser for dispensing fluid from container means, said dispenser comprising:

fluid withdrawal means for withdrawing fluid from the fluid container means, said fluid withdrawal means including an electrically-operated pump;

electrically-operated injection means for injecting fluid withdrawn from the container means into a living body, said injection means including a single injection orifice for a selected group of bodies to be injected; and

power source means for supplying electrical power to said pump and to said injection means.

3. A hypodermic fluid dispenser for dispensing fluid from container means holding a reservoir of fluid, said dispenser comprising:

fluid withdrawal means for withdrawing a predetermined dose of said fluid from the fluid container means, said fluid withdrawal means including a pump;

electrically-operated injection means for injecting fluid withdrawn from the container means into a body, said injection means including a single injection orifice for a selected group of bodies to be injected; and

power source means for supplying electrical power to said injection means.

4. A hypodermic fluid dispenser for dispensing fluid from a fluid container having a reservoir of the fluid, said dispenser comprising:

fluid withdrawal means for withdrawing fluid from the reservoir in the fluid container means, said fluid withdrawal means including fluid inlet means for receiving fluid from the container and fluid outlet means for discharging fluid;

compressible chamber means for receiving fluid from the fluid outlet means of said fluid withdrawal means;

electrically-operated compressing means for compressing said compressible chamber means for applying pressure to fluid in said compressible chamber means; and

injection means operatively connectable with said compressible chamber means for injecting fluid from said compressible chamber means into a body in response to the operation of said compressing means.

5. A hypodermic fluid dispenser according to claim 4 wherein said injection means comprises a plurality of injection orifices for consecutively passing fluid from said compressible chamber means into consecutive bodies being injected.

6. A hypodermic fluid dispenser according to claim 4 wherein said injection means includes a single injection orifice for passing fluid into a selected group of bodies being injected.

7. A hypodermic fluid dispenser according to claim 4 wherein said injection means comprises a plurality of injection needles for consecutively injecting fluid from said compressible chamber into consecutive bodies being injected.

8. A hypodermic fluid dispenser according to claim 4 wherein said dispenser comprises means for operatively connecting a power source means to said compressing means for supplying electrical power to said compressing means.

9. A hypodermic fluid dispenser according to claim 4, wherein said dispenser further comprises rechargeable power source means for supplying electrical power to said compressing means.

10. A hypodermic fluid dispenser according to claim 4, and further comprising means for connecting charged power source means to said compressing means to replace depleted power source means.

11. A hypodermic fluid dispenser according to claim 4 wherein fluid withdrawal means comprises means for establishing a predetermined dose of the fluid to be withdrawn

12. A hypodermic fluid dispenser according to claim 4 wherein said withdrawal means comprises a manually-operated pump.

13. A hypodermic fluid dispenser according to claim 4 wherein said withdrawal means comprises an electrically-operated pump.

14. A hypodermic fluid dispenser according to claim 4, and further including means for operatively connecting the inlet means of said fluid withdrawal means to a detachable and replaceable container, depleted containers being replaceable with containers holding the desired fluid.
