Abstract

An angiographic injector having a separable console selecting and displaying injector functions and parameters. Microprocessors provide serial data transmission between console and injector base, and between injector head and injector base. A microprocessor in the base controls the injector.

Claims

1. An angiographic injector for injecting liquid into the vascular system of a living being for diagnostic, therapeutic and like purposes comprising:

a console having means operable for selecting injector functions, for setting injector parameters, and for displaying information relating to said functions and parameters into an injector head;

a motor operated injector head for injecting said liquid into the vascular system of a living being in accordance with said preselected parameters and functions;

a base support having means for supporting said console;

electronic hardware for controlling said injector head in response to said means operable for selecting injector functions, for setting injector parameters, and for displaying information relating to said functions and parameters into said injector head, said hardware being located in said base support;

means for positively securing but readily-releasing said console from said base support so as to allow said console to be readily removed from said base support and moved to a remote location for operational use.

2. The invention of claim 1, wherein said console includes serial data transmission means for transmitting signals relating to injector functions and parameter settings to the injector.

3. The invention of claim 1, wherein said injector head includes a status transmitter having serial data transmission means for transmitting signals relating to head status to said injector for display by the first said means.

4. An angiographic injector for injecting liquid into the vascular system of a living being for diagnostic, therapeutic and like purposes comprising:

a control console having means for selecting injector functions, for setting injector parameters and for displaying information relating to said functions and parameters into an injector head;

a motor operated injector head for injecting said liquid into the vascular system of a living being in accordance with said preselected parameters and functions;

a base support housing;

electronic hardware for controlling said powerhead in response to the preselected parameters selected on said console, said electronic hardware being located in said base support housing;

a column support extending from said base support housing for supporting said console;

means for positively securing but readily-releasing said console to said column support so as to allow said console to be readily removed from said column and moved to a remote location for operational use.

5. An angiographic injector for injecting liquid into a vascular system of a living being for diagnostic, therapeutic, and like purposes comprising a console having means for operably selecting injector functions, for selecting injector parameters, and for displaying information related to said functions and parameters into an injector head, a motor operated injector head for injecting said liquid into the vascular system of a living being in accordance with said preselected parameters and functions;

electronic hardware means for controlling operation of said injector head in response to preselected parameter settings selected in said console, means for positively securing but readily-releasing said injector head from the remaining portion of said angiographic injector, said injector head remaining operable for injecting fluid into vascular system of a living being despite said injector head being separated from said angiographic injector, said injector head having a status transmitter having serial data transmitting means for transmitting signals to said electronic hardware means for eventual display on said console.
