Abstract

A system for dispensing Botox, anti-venom, local chemotherapy, anesthetics, aesthetic fillers, endogen materials, fat for aesthetic surgery, stem cells, and lethal injection compounds though a sterile syringe. They system uses pressure, generated by a pump unit, to apply force on a syringe containing the materials to be delivered into the patient'"'"'s body. The volume rate and volume per injection are adjustable through user inputs. The injection occurs when the physician activates a momentary switch. The system provides precise control of the injected material thus minimizing the inaccuracies associated with manually injected materials. Additionally, the simplicity of the system eases cleaning and sterilization practices thus minimizing risks of transferring undesirable transmissible agents.

Claims

1. A dispensing device for injecting toxic or otherwise dangerous medical compositions subcutaneously comprising:

a sterile, autoclavable, hand piece having a sterile syringe removably mounted therein, said syringe comprising a plunger slidably mounted within a syringe barrel, said hand piece having a first driving mechanism therein connected to said syringe for actuating said syringe plunger to inject said compositions subcutaneously into a patient;

a remote control unit having a second driving mechanism mounted therein;

a connection means between said first and second driving mechanisms that transfers motion of the second driving mechanism in the remote control unit to the first driving mechanism in the hand piece without any time delay, change in displacement of the injection and change in the speed of the injection; and

said hand piece having a actuator mounted thereon fort actuating said second driving mechanism in said remote control unit.

2. A dispensing device as claimed in claim 1, further comprising;

said remote control unit having a reader (bar code, qr, rfid) that detects the serial number of the syringe to be mounted in the hand piece;

a microprocessor connected to the remote control unit wirelessly or electrically wired having software or an algorithm stored therein that allows the operation of the remote control unit after the syringe is verified;

a data storage system local or remote to said dispensing device for maintaining records of any or combination of the following;

patient data, medication used, injection rate and amount and date of injections.

3. A dispensing device as claimed in claim 1, further comprising;

said first and second driving mechanisms comprise hydraulic piston/cylinder assemblies connected by a flexible hydraulic tube.

4. A dispensing device as claimed in claim 3, wherein said flexible tube has an outside diameter of between 1/32 and ⅛

of an inch and a length between 2-12 feet, said hydraulic cylinders and said flexible tube being is filled with an incompressible liquid thereby providing an incompressible medium to deliver controlled thrust from the piston of the second driving mechanism to the piston of the first driving mechanism to the plunger of the syringe located in the hand unit.

5. A dispensing device as claimed in claim 1, wherein said connection means is a Bowden cable.

6. A dispensing device as claimed in claim 1, wherein said connection means is a Bowden cable.

7. A dispensing device as claimed in claim 3, wherein said second driving mechanism further comprises a DC electric rotary motor and a potentiometer for controlling the speed of the motor and a linear screw drive that converts the rotary motion of the electric rotary motor to linear motion to drive the piston of the piston/cylinder assembly of the second driving mechanism to drive the non-compressible liquid in the hydraulic tube and apply a force to the piston of the piston/cylinder assembly of the first driving mechanism cylinder to drive the plunger of the syringe in the hand piece.

8. A dispensing device as claimed in claim 3, wherein said the hydraulic piston-cylinder assembly located in the hand piece is also a sterile syringe.

9. A dispensing device as claimed in claim 3, wherein said the hydraulic tube is a sterile medical tube.

10. A dispensing device as claimed in claim 3, wherein said hydraulic piston-cylinder assembly located in the remote control unit is also a sterile syringe.

11. A dispensing device as claimed in claim 7, wherein said actuator comprises a momentary electric switch which is wirelessly or wired to said DC electric motor in said remote control unit.

12. A dispensing device as claimed in claim 1, wherein said injection compounds include any one of the following:

Botox, anti-venom, local chemotherapy, anesthetics, aesthetic fillers, endogen materials, fat for aesthetic surgery, stem cells, lethal injection compounds.

13. A dispensing device as claimed in claim 1, wherein the connection means is any one of the following:

a. rotating flexible cable actuator,

b. electroactive polymer actuator,

c. thermo bimorph actuator.

14. A dispensing device as claimed in claim 11, wherein said momentary electric switch is easily removably clipped to the hand piece covered by a disposable sterile sheath.
