Abstract
Abstract A patient monitor includes an enclosure which is secured to the bed of a patient. The enclosure is electrically connected with a nurse's call panel and the enclosure serves to mount a jack which is electrically connected to the nurse's call panel. This jack includes a normally closed switch which is opened when a mating plug is installed in the jack. The plug is connected by a cord to the gown of the patient in the bed. When the patient attempts to leave the bed the patient's motion pulls the plug from the jack, thereby allowing the switch to close and signalling via the call panel the patient's attempt to leave the bed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
107 words
In combination with a call panel of the type which activates a remote alarm in response to a predetermined signal and is situated adjacent to a bed, the improvement comprising: a cord having a first end and a second end; means, coupled to the first end of the cord and the call panel, for generating the predetermined signal when the cord is pulled; and means for securing the second end of the cord to clothing of a patient in the bed; said cord, generating means, and securing means cooperating to cause the call panel to activate the remote alarm when a patient attempts to leave the bed.
Claim 2
Dependent Claim
107 words
In combination with a call panel of the type which activates a remote alarm in response to a predetermined signal and is situated adjacent to a bed, the improvement comprising: a cord having a first end and a second end; means, coupled to the first end of the cord and the call panel, for generating the predetermined signal when the cord is pulled; and means for securing the second end of the cord to clothing of a patient in the bed; said cord, generating means, and securing means cooperating to cause the call panel to activate the remote alarm when a patient attempts to leave the bed.
Claim 3
Dependent Claim
58 words
The invention of claim 1 wherein the generating means comprises: a plug connected to the first end of the cord; an enclosure; a socket mounted on the enclosure and sized to receive the plug; a cable interconnecting the socket with the call panel; and means for generating the predetermined signal when the plug is absent from the socket.
Claim 4
Dependent Claim
38 words
The invention of claim 2 wherein the socket is mounted to the enclosure by an elongated flexible member such that the orientation of the socket is variable in response to forces applied to the socket by the cord.

Claim 7
Dependent Claim
210 words
In combination with a call panel of the type which activates a remote alarm in response to a predetermined signal and is situated adjacent to a hospital bed, the improvement comprising: a cord having a first end and a second end; a plug connected to the first end of the cord; means for securing the second end of the cord to clothing of a patient in the bed; a jack sized to receive the plug, said jack having two terminals which are shorted together when the plug is absent from the jack and are open circuited when the plug is in the jack; an enclosure; a flexible tube having a first end secured to the jack and a second end mounted to the enclosure such that the jack moves in response to forces applied via the cord to more nearly align the jack with said forces; means for securing the enclosure to the bed; conductor means which pass through the tube for electrically interconnecting the call panel with the two terminals of the jack; said call panel responsive to a short circuit between the two terminals of the jack to activate the remote alarm when a patient pulls the plug out of the jack in attempting to leave the bed.
Claim 8
Dependent Claim
210 words
In combination with a call panel of the type which activates a remote alarm in response to a predetermined signal and is situated adjacent to a hospital bed, the improvement comprising: a cord having a first end and a second end; a plug connected to the first end of the cord; means for securing the second end of the cord to clothing of a patient in the bed; a jack sized to receive the plug, said jack having two terminals which are shorted together when the plug is absent from the jack and are open circuited when the plug is in the jack; an enclosure; a flexible tube having a first end secured to the jack and a second end mounted to the enclosure such that the jack moves in response to forces applied via the cord to more nearly align the jack with said forces; means for securing the enclosure to the bed; conductor means which pass through the tube for electrically interconnecting the call panel with the two terminals of the jack; said call panel responsive to a short circuit between the two terminals of the jack to activate the remote alarm when a patient pulls the plug out of the jack in attempting to leave the bed.
Claim 9
Dependent Claim
42 words
The invention of claim 2 wherein the generating means further comprises an additional socket mounted on the enclosure, said additional socket comprising two terminals which are normally open circuited and capable of generating the predetermined signal when said terminals are close circuited.
