Abstract

A hypodermic syringe and a plurality of single use cartridges able to be successively loaded into said syringe for providing rapid dispensing of a medicant to numerous users without possibility of contamination. The cartridges are continuously fed through the syringe for the quick and efficient inoculation of patients. An operator inserts a needle into a patient by pushing in a trigger. Prior to the needle being inserted into the patient, a disinfectant is dispersed from the cartridge to maintain sterility. An operator then pushes in a plunger forcing the medication through the needle into the patient. The plunger is pulled back into its original location after use. The needle is pulled back with the plunger out of the patient'"'"'s skin and back into the cartridge. A new cartridge on a clip is then advanced into the syringe for use in inoculating the next patient needing medication. The syringe and cartridge dispenser further maintains a sterile environment during successive vaccinations reducing the transmission of any disease from patient to patient.

Claims

1. A cartridge for dispensing a liquid comprising:

a housing having a channel extending therethrough and including a first membrane sealing a first end thereof and a second membrane sealing a second end thereof;

a reservoir positioned within the housing for retaining the liquid, said first membrane forming an end of said reservoir;

a hollow needle positioned between an end of said reservoir and said second membrane for receiving the liquid therethrough; and

an accordion sleeve having a collapsible section and a tip section, said sleeve surrounding said needle when said accordion section is selectively collapsed, said needle is caused to extend from said tip section for penetrating an adjacent membrane and into a user and said liquid in said reservoir is forced through said needle and into the user.

2. The cartridge as recited in claim 1, further comprising a disinfectant, said disinfectant being positioned within a space formed between said housing, sleeve and second membrane.

3. The cartridge as recited in claim 2, wherein said tip section further comprises an edge sufficient to pierce said second membrane and apply said disinfectant to the user prior to said needle injecting the user.

4. The cartridge as recited in claim 1, wherein said hollow needle includes a base forming an end of said reservoir opposite said first membrane, said base having a diameter greater than a diameter of said reservoir.

5. The cartridge as recited in claim 1, wherein said liquid is a medicant.

6. An apparatus for continuously dispensing the contents of a plurality of cartridges in succession comprising:

a housing, said housing including

a dispensing section, said dispensing section including

a barrel extending along a length of said dispensing section for successively receiving a respective one of the plurality of cartridges containing a liquid therein;

means for dispensing the liquid contained in the cartridge; and

a handle section extending from said dispensing section for gripping by a user, said handle section including means for selectively activating said dispensing means to dispense the liquid contained in a respective cartridge positioned in said barrel.

7. The apparatus as recited in claim 6, wherein said dispensing means comprises:

a piston having a geared section positioned adjacent said barrel, said geared section mating with said handle section;

a pressure plate moveably connected within said piston; and

a plunger connected to an end of said pressure plate and extending out from both said tube and said barrel.

8. The apparatus as recited in claim 7, wherein said tube includes a piercing edge for selectively piercing a membrane on a cartridge.

9. The apparatus as recited in claim 7 wherein said selectively activating means comprises:

a trigger having a geared section, said trigger being pivotally connected within said handle section and mating with said geared section on said tube, wherein upon pivoting said trigger, said tube is caused to move towards said barrel.

10. A method for dispensing the content of a cartridge in a syringe, comprising the steps of:

loading a cartridge including a medicant into the syringe;

manipulating a trigger of said syringe;

moving a piston of the syringe against a sleeve of the cartridge thereby puncturing a membrane at an end of the cartridge causing a disinfectant to be released onto a patient and a needle to be injected into the patient;

forcing a plunger and pressure plate forward against a sleeve within the cartridge;

causing a medicant contained within the cartridge to flow through the hollow needle;

delivering the medicant to said patient through said hollow needle;

pulling said plunger back to an initial position thereby returning the piston to its initial position and retracting said hollow needle inside said cartridge;

removing the spent cartridge from the syringe; and

reloading the syringe with an adjacent cartridge.
