Appl. No.:

09/628180

Inventors:

Thor R. Halseth - Simi Valley CA
John M Barker - Ventura CA
Michael J. Botich - Oxnard CA

Assignee:

MDC Investment Holdings, Inc. - Wilmington DE

International Classification:

A61B 500

US Classification:

600585, 600434, 600573, 606167, 60416412

Abstract:

A needle-bearing medical device is provided for inserting a guide wire. After use the needle is shielded to render the contaminated needle safe to prevent inadvertent needle sticks. The device includes a housing and a needle having a sharpened tip. A biasing element biases the needle toward a position in which the sharpened tip is shielded. A connector is provided for attaching a fluid collection device to the guide wire insertion device, if desired. A guide is configured for guiding the guide wire through the port and into the needle. A method is also provided for using the medical device, in which the needle is inserted vascularly into a patient. A fluid collection device is attached to the connector of the device and blood is drawn into the fluid collection device to ensure that the needle is properly positioned within a vein or artery of the patient. A guide wire is then inserted into the patient through the device and the needle is retracted to shield the needle. In one embodiment, the device includes a second port through which the guide wire is inserted while the fluid collection device is attached to the insertion device.

US Classification:

606108, 604192, 600576

Abstract:

A catheter insertion device is provided for inserting an over-the-needle catheter. The device includes an insertion needle that is retractable into the housing of the device after use to prevent exposure to the contaminated needle. The needle retainer releasably retains the needle in an extended position against the rearward bias of the biasing element. The needle retainer engages the hub of the catheter so that when the catheter is removed from the insertion device, the needle retainer automatically releases the needle. The biasing element then propels the needle rearwardly into the housing of the device. A method for inserting a catheter is also provided, in which the needle is hooded by the catheter during the insertion procedure.

US Classification:

358444, 382305, 382304, 358 116, 358 117, 358 19, 358407

Abstract:

A system is provided for scanning batch-type documents containing indicia on either a single side or on two sides of each document sheet. Misfeeds through a scanning device are identified by comparison of an anticipated number of pages with an actual number of scanned pages. Similar misfeeds may be identified by comparison of first and second series of pages in two-sided documents. Automatic collating of scanned pages is then performed where desired. The automatic collating may be based upon simple interleaving of pages, or upon recognition of page identifiers, such as page numbers in common or anticipated regions of the page. The scanning, analysis and collating operations may be followed by other processing steps, including transmission of facsimiles, printing, copying, and so forth.

US Classification:

710 10, 710 8, 710 62, 713323, 358 115

Abstract:

A system for seamless distributed job control between a multifunction peripheral and a host. A host, such as a personal computer, is linked with one or more multifunction peripherals. Each multifunction peripheral has at least scanning and printing capability. However, the peripherals do not require extensive memory or processing capability, because the processing and storage of data is accomplished by the host. A user potentially may operate the peripheral through a peripheral interface or through a user interface of the host.

US Classification:

37910009, 358407, 37910202

Abstract:

A facsimile machine provides firmware to remotely activate and deactivate fax forwarding. The firmware enables a user to remotely activate or deactivate fax forwarding through an email, fax, or a telephone. The facsimile machine may be set by the user to activate and deactivate fax forwarding at a predetermined activation time and a predetermined deactivation time. If fax forwarding with local printing is activated, the facsimile machine locally prints a fax after the fax is forwarded. The facsimile machine may be a multifunctional peripheral.

US Classification:

358468, 382317

Abstract:

A technique is disclosed for programming instructions into a system including a scanning device. The instructions are defined by machine and human readable indicia on an instruction support sheet. A document is associated with the instruction support sheet and may be processed with the instructions. Desired instructions may be selected by annotations on the instruction sheet. The instruction sheet is then scanned to encode the selections. Data sets corresponding to the composition of the instruction sheet are accessed to interpret the selected instructions. Based upon the selected instructions, operations are performed on the document. The operations may include scanning, transmission of facsimiles, transmission of electronic messages, archival storage, and so forth. The instruction sheet may be composed and configured in accordance with needs of individual users. The scanning device may be associated with a computer system or may be a stand-alone device.
