Abstract
Abstract A device for arterial compression to promote formation of a blood clot or thrombus which closes an arterial puncture is constructed with an inflatable transparent expandable pad unit. An adjustable support means mounted to a base supports the transparent pad in its required operative position. The patient is properly located by body-positioning pads located on the base with a pair of belts maintaining the patient in such operative position. After the unit is placed over the arterial opening, the unit is inflated to a point where blood does no more than merely ooze from the arterial opening and pulsing indications of blood pressure within the artery in question become observable on a gauge connected to read pressure within the transparent chamber. The arterial compression is observable through the pad and the clot is usually formed properly a short time after blood stops oozing.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
176 words
A medical device for applying controlled pressure to a localized area of a body comprising a base having bodypositioning means, a securing means for holding a body on said body-positioning means, a pad unit including an expandable pressure chamber partially defined by a extendable, flexible, transparent membrane and partially defined by a transparent rigid support for said membrane, an adjustable support means for mounting said transparent rigid support relative to said base, means for securing said adjustable support means in adjusted position; a pump means connected to said chamber for inflation thereof whereby said membrane is expanded into engagement with said localized area of the body when said support means positions said chamber adjacent said localized area; means connected to said chamber for indicating pressure changes therein; a one-way valve means interposed between said pump means and said chamber to permit pressure buildup in the latter; whereby conditions at the localized area of the body are viewable through sAid transparent rigid support and said membrane while said membrane is in operative engagement with such localized area.
Claim 2
Dependent Claim
176 words
A medical device for applying controlled pressure to a localized area of a body comprising a base having bodypositioning means, a securing means for holding a body on said body-positioning means, a pad unit including an expandable pressure chamber partially defined by a extendable, flexible, transparent membrane and partially defined by a transparent rigid support for said membrane, an adjustable support means for mounting said transparent rigid support relative to said base, means for securing said adjustable support means in adjusted position; a pump means connected to said chamber for inflation thereof whereby said membrane is expanded into engagement with said localized area of the body when said support means positions said chamber adjacent said localized area; means connected to said chamber for indicating pressure changes therein; a one-way valve means interposed between said pump means and said chamber to permit pressure buildup in the latter; whereby conditions at the localized area of the body are viewable through sAid transparent rigid support and said membrane while said membrane is in operative engagement with such localized area.
Claim 3
Dependent Claim
36 words
A medical device as set forth in claim 1 in which includes support means permitting linear movement of said unit in first and second mutually perpendicular planes and for permitting universal pivotal movement of said unit.
Claim 4
Dependent Claim
35 words
A medical device as set forth in claim 1 in which one end of said support means is secured to said base and said unit is secured to the other end of said support means.
Claim 5
Dependent Claim
31 words
A device as set forth in claim 1 in which the pad unit also includes a framelike member holding the periphery of said transparent membrane clamped against the transparent rigid support.
