Abstract
Abstract A bio-medical injector apparatus comprising a base unit having a skin engaging portion disposed at an angular orientation with respect to the longitudinal axis of the base unit for supporting and maintaining a hypodermic needle at an optimum angular orientation for effecting an injection procedure, a carriage assembly reciprocally mounted on the base unit and carrying the hypodermic needle simultaneously therewith, a motor drive unit operably connected with the hypodermic needle for the preloading thereof with a suitable medication, a solenoid secured to the base unit and operably connected with the carriage assembly for a controlled reciprocation thereof for effecting the injection operation of the needle, and an electronic circuitry operably connected between a power supply and the motor drive and the solenoid for creating the logic necessary to perform the functions of the injector apparatus.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
161 words
A bio-medical injector apparatus comprising a base unit, carriage means reciprocally secured to the base unit, hypodermic needle means removably secured to the carriage means and movable simultaneously therewith, solenoid means carried by the base unit and operably connected with the carriage means for simultaneous reciprocation of the carriage means and hypodermic needle means, motor drive means carried by the carriage means and operably connected with hypodermic needle means for injection of the contents of the hypodermic needle means during an injection procedure, power means operably connected with solenoid means and motor drive means for supplying electrical power thereto, and electronic circuitry means including sensor means for detecting the presence of blood on the hypodermic needle means, said electronic circuitry means being interposed between the power supply means and the solenoid means and motor drive means for providing the logic required to perform the operation of the injector apparatus to stop the operation of the hypodermic needle upon detection of blood.
Claim 2
Dependent Claim
161 words
A bio-medical injector apparatus comprising a base unit, carriage means reciprocally secured to the base unit, hypodermic needle means removably secured to the carriage means and movable simultaneously therewith, solenoid means carried by the base unit and operably connected with the carriage means for simultaneous reciprocation of the carriage means and hypodermic needle means, motor drive means carried by the carriage means and operably connected with hypodermic needle means for injection of the contents of the hypodermic needle means during an injection procedure, power means operably connected with solenoid means and motor drive means for supplying electrical power thereto, and electronic circuitry means including sensor means for detecting the presence of blood on the hypodermic needle means, said electronic circuitry means being interposed between the power supply means and the solenoid means and motor drive means for providing the logic required to perform the operation of the injector apparatus to stop the operation of the hypodermic needle upon detection of blood.
Claim 3
Dependent Claim
73 words
A bio-medical injector apparatus as set forth in claim 1 wherein surface means is provided on the base unit and angularly oriented with respect to the longitudinal axis of the base unit for engagement with a skin area wherein the injection procedure is to take place, the angular orientation of the surface means cooperating with the carriage means for supporting the hypodermic needle means at an optimum angular orientation for the injection procedure.
Claim 4
Dependent Claim
32 words
A bio-medical injector apparatus as set forth in claim 2 wherein the angular orientation of the surface means with respect to the longitudinal axis of the base unit is forty five degrees.
Claim 5
Dependent Claim
73 words
A bio-medical injector apparatus as set forth in claim 1 wherein the hypodermic needle means includes a housing for receiving a medication dosage therein, plunger means reciprocally disposed within the housing and movable in one direction for drawing a quantity of the medication therein and in another direction for ejecting the medication therefrom, and connecting means extending between the motor drive means and the plunger means for reciprocation thereof during an injection procedure.
Claim 6
Dependent Claim
76 words
A bio-medical injector apparatus as set forth in claim 1 wherein the electronic circuitry means comprises data input means operably connected with the power supply means, motor drive circuit means operably connected with the data input means, timer circuit means operably connected with the data input means and sensor circuit means and motor drive means, data output means operably connected with the sensor circuit means and timer circuit means and motor drive means and solenoid means.
Claim 7
Dependent Claim
59 words
A bio-medical injector apparatus comprising: a base unit; carriage means reciprocally secured to the base unit; hypodermic needle removably secured to the carriage means and movable simultaneously therewith; sensing means for detecting the presence of blood on the hypodermic needle; and, means responsive to said sensor means for stopping the operation of the hypodermic needle upon detecting said blood.
Claim 8
Dependent Claim
59 words
A bio-medical injector apparatus comprising: a base unit; carriage means reciprocally secured to the base unit; hypodermic needle removably secured to the carriage means and movable simultaneously therewith; sensing means for detecting the presence of blood on the hypodermic needle; and, means responsive to said sensor means for stopping the operation of the hypodermic needle upon detecting said blood.
