First Claim
1. A dispensing appliance for use in insertion of a therapeutic thin elongate article that extends into a living body at an insertion site on the body;
- said appliance comprising;
a shield for covering such site and immediately surrounding area;
a guide conduit, defined through the shield, for receiving and surrounding a portion of such thin elongate article outside the body and for guiding such article to such insertion site;
a reservoir containing a substance;
means, connected with the substance reservoir and with the shield, for securing such substance reservoir to the shield;
means, connected with the substance reservoir and with the shield, for conveying such substance from such reservoir to the conduit; and
means, opened at insertion of such article through the guide conduit, for retaining substance in the appliance before use of the appliance;
whereby substance from such reservoir is applied to such thin elongate article and thereby to such body; and
wherein;
the shield defines a first side that faces such body during use, and a second side that faces away from such body during use; and

Abstract
The appliance lubricates and disinfects the catheter, tube, or other article, as the catheter is inserted into or maintained in a patient'"'"'s urethra or other body opening. It also mildly anesthetizes the interior of the body opening itself. A contoured shield covers the body site through which the article extends; the shield has flexible stabilizing flaps or a sealing band, or a flange, to fit against the patient'"'"'s penis or perineum. The catheter is threaded through the conduit, which penetrates the appliance. A reservoir is secured outside or, preferably, inside the appliance. The shield is transparent, and the reservoir contains a conspicuous disinfectant/lubricant/analgesic substance. The reservoir is positioned to provide the user an unobstructed line of sight for ready and accurate positioning of the guide conduit and thus the catheter. Membranes across the conduit retain the substance in the appliance. The membranes are broken at the time of insertion to release the substance into contact with the article and the body passageway. The membranes are broken either by the article itself, as it is threaded through the appliance and inserted into the body, or by manual squeezing of part of the appliance.
