Abstract

A portable syringe dispenser system capable of holding one or more syringes containing different types of fluid medicine therein. Filled syringes, holding enough fluid medicine for multiple injections, are placed into syringe holders in the dispenser and inserted into a sterile mixing chamber. The dosage of each type of fluid medicine in each syringe is independently adjusted employing a dose adjusting indicator system. An activation system allows all doses of the fluid medicine to be simultaneously injected through a replaceable sterile needle. The sterile needle can remain on the dispenser system. The sterile needle maintains its sterility by sealing it with a sealing cap. This allows the needle to be reused. In addition, a dosage/time recording unit can be attached to the portable syringe dispensing system to accurately record at least the time, date and amount of fluid medicine injected. A plurality of these recordings can be made.

Claims

1. A syringe dispenser system, comprising:

a housing including a plurality of dose adjustable syringe holders therein;

a plurality of syringes inserted into said plurality of dose adjustable syringe holders, said plurality of syringes each including fluid medicine and capable of several sequential dose injections and each having a needle and plunger attached thereto, said fluid medicine being dispensed simultaneously from each of said plurality of syringes; and

activation means contacting each of said plurality of syringes, for simultaneously dispensing said fluid medicine from said plurality of syringes.

2. A syringe dispenser system according to claim 1, further comprising:

adjusting means, coupled to each of said plurality of dose adjustable syringe holders, for adjusting the dosage of fluid medicine in each of said plurality of dose adjustable syringes, said adjusting means including;

indicator means on one of or both of each of said plurality of dose adjustable syringe holders and said syringes;

threaded rods, a threaded rod provided for each of said plurality of syringes and coupled to said plungers;

threaded tubes threaded onto each of said threaded rods, respectively;

an indicator dial, threaded onto each of said threaded tubes and including;

calibration means extending through said indicator dial and fastening to each of said threaded tubes, said indicator dial pointing to said indicator means on each of said plurality of dose adjustable syringe holders and said syringes;

a spring loaded activation bar, located across a middle portion of each of said dose adjustable syringe holders and contacting each of said threaded tubes, for simultaneously releasing said fluid medicine from said plurality of syringes.

3. A syringe dispenser system according to claim 2, wherein said calibration means aligns said indicator dial with said indicator means.

4. A syringe dispenser system according to claim 2, further comprising:

sterile mixing manifold means having a multiple septum opening for receiving each needle from said plurality of syringes and a single septum opening; and

a screw-on needle, screwed into said single septum opening of said sterile mixing manifold means, for simultaneously receiving and dispensing said fluid medicine from said sterile mixing manifold means.

5. A syringe dispenser system according to claim 1, wherein said sterile mixing manifold means comprises:

a first septum into which each needle of said plurality of syringes is inserted;

a passage for receiving each needle, each passage combining into one combined passage, said combined passage being joined at a portion where said screw-on needle attaches; and

a second septum into which said screw-on needle passes to connect with said combined passage.

6. A syringe dispenser system according to claim 5, further comprising a needle sealing cap for covering said screw-on needle.

7. A syringe dispenser system according to claim 6, wherein said needle sealing cap has an open end for receiving said screw-on needle and a sealed end, said needle sealing cap further comprises:

a septum located inside said needle sealing cap near said sealed end; and

sterilizing means packed inside said needle sealing cap for sterilizing said screw-on needle.

8. A syringe dispenser system according to claim 7, wherein said sterilizing means includes alcohol soaked gauze.

9. A syringe dispenser system according to claim 4, wherein each one of said plurality of syringes contains a different type of fluid medicine.

10. A syringe dispenser system according to claim 9, further comprising:

a spring loaded activation bar having a large force stored therein, attached to said syringe dispenser system, for arming said syringe dispenser system for an injection;

an arming knob, coupled to said spring loaded activation bar, for arming said spring loaded activation bar; and

injection means, coupled to said spring loaded activation bar, for releasing the large force stored in said spring loaded activation bar and simultaneously releasing the fluid medicine in each of said plurality of syringes into said screw-on needle.

11. A syringe dispenser system according to claim 10, wherein said plungers are independently and simultaneously moved when said injection button is pushed.

12. A syringe dispenser system according to claim 9, further comprising:

a battery within said housing;

a motor connected to said battery in said housing; and

a microswitch in each of said plurality of dose adjustable syringe holders, coupled to said motor, said injection means and said activation bar, for simultaneously releasing the fluid medicine in each of said plurality of syringes when a small force is applied to said injection means.

13. A syringe dispenser system according to claim 9, further comprising:

an injection button, coupled to said spring loaded activation bar, for releasing said spring loaded activation bar and activating said plungers,

thereby simultaneously dispensing said fluid medicine in said plurality of syringes.

14. A syringe dispenser system, according to claim 2, further comprising a dosage/time recording system.

15. A syringe dispenser system according to claim 14, wherein said dosage/time recording system comprises:

indicator dial sensor means, coupled to said adjusting means, for detecting a position of said indicator means;

zeroing means for zeroing said indicator dial sensor means;

a liquid crystal display (LCD), coupled to said indicator dial sensor means, for displaying an output of said indicator dial sensor means; and

memory means, coupled to said LCD, for storing information including the amount of fluid medicine injected, date and time.

16. A syringe dispenser system according to claim 15, further comprising:

clock means, incorporated into said LCD, for determining and outputting the time and date to said memory means; and

set means, coupled to said clock means, for setting the time and date of said clock means.

17. A syringe dispenser system according to claim 16, further comprising:

recall means, incorporated into said memory means, for recalling said information stored in said memory means; and

downloading means for downloading the recalled information.

18. A syringe dispenser system according to claim 17, wherein said indicator dial sensor means can be one of an optical, electrical and mechanical device.

19. A syringe dispenser system, comprising:

a syringe holding and guiding system including syringes filled with fluid medicine;

a dose adjusting indicator system connected to said syringe holding and guiding system;

an activation system coupled to said dose adjusting indicator system, said activation system including;

an injection button, coupled to said syringes, for simultaneously releasing fluid medicine in each of said syringes; and

a spring loaded arming knob, coupled to said injection button, for arming said injection button for an injection; and

sterile mixing manifold means, coupled to said syringes, for receiving and simultaneously dispensing said fluid medicine in said syringes.
