Device for positioning cardiographic sensor
First Claim
1. In an apparatus for taking cardiograms having an echocardiograph and an electrocardiograph, a device for positioning and for fixing the position of an echosignal sensor and the positions of sensors of electric signals, said echosignal and electric signal sensors being connected, respectively, to said echocardiograph and said electrocardiograph, said device comprising:
- a base,means for fixing the base on the patient'"'"'s body within the zone under examination,a movable carriage,two mutually perpendicular guideways carried by said base for mounting and for guiding movement of the movable carriage,retainers for locking the carriage in a required position in the guideways,a swivel head rotatable with respect to said carriage about a common point to be examined and having a sleeve for accommodating the echosignal sensor and for holding said echosignal sensor in contact with the patient'"'"'s body, said swivel head being rotatable to place said echosignal sensor in one of several monitoring positions while said carriage is locked in the required position in said guideways, said swivel head and sleeve being rotatable about the common point, wherein the swivel head incorporates a hemispherical case with a flat base mounted on the carriage and defining a through opening in a central portion thereof for said sleeve and the swivel head further including two partly spherical members carrying said sleeve and embracing the hemispherical case, one from outside and the other from inside;
means for mounting said members to allow said members to be moved together and apart so that when said members are moved apart, said members can be swivelled along with the sleeve to an angle with respect to the common point to be examined, and when said members are moved together, said members and the sleeve are fixed rigidly in position; and
at least three sockets connected to and electrically insulated from said base, said sockets adapted for accommodating said sensors of electric signals.

Abstract
Described herein is a device for positioning and fixing an echosignal sensor and sensors of electric signals in an apparatus for taking cardiograms having an echocardiograph and an electrocardiograph. The device has a base with two mutually perpendicular guideways for the movable carriage to travel thereon. The carriage carries a swivel head with a socket for accommodating the echosignal sensor. The swivel head is angularly displaceable in such a way that the centers of rotation of the socket and of the head itself coincide. The sensors of electric signals are fixed stationary on the base.

In an apparatus for taking cardiograms having an echocardiograph and an electrocardiograph, a device for positioning and for fixing the position of an echosignal sensor and the positions of sensors of electric signals, said echosignal and electric signal sensors being connected, respectively, to said echocardiograph and said electrocardiograph, said device comprising:
-
a base, means for fixing the base on the patient'"'"'s body within the zone under examination, a movable carriage, two mutually perpendicular guideways carried by said base for mounting and for guiding movement of the movable carriage, retainers for locking the carriage in a required position in the guideways, a swivel head rotatable with respect to said carriage about a common point to be examined and having a sleeve for accommodating the echosignal sensor and for holding said echosignal sensor in contact with the patient'"'"'s body, said swivel head being rotatable to place said echosignal sensor in one of several monitoring positions while said carriage is locked in the required position in said guideways, said swivel head and sleeve being rotatable about the common point, wherein the swivel head incorporates a hemispherical case with a flat base mounted on the carriage and defining a through opening in a central portion thereof for said sleeve and the swivel head further including two partly spherical members carrying said sleeve and embracing the hemispherical case, one from outside and the other from inside; means for mounting said members to allow said members to be moved together and apart so that when said members are moved apart, said members can be swivelled along with the sleeve to an angle with respect to the common point to be examined, and when said members are moved together, said members and the sleeve are fixed rigidly in position; and at least three sockets connected to and electrically insulated from said base, said sockets adapted for accommodating said sensors of electric signals. - View Dependent Claims (2, 3, 4, 5)

6. A device for positioning an echosignal sensor and sensors of electric signals on a patient'"'"'s body, said device comprising:
-
a base positionable on the body of a patient so that the patient'"'"'s body supports the device; first and second guide means, said first guide means being fixed to said base and supporting said second guide means for movement; a carriage slidably mounted on said second guide means, said carriage being movable in a first direction by movement of said second guide means along said first guide means and being movable in a second direction by movement of said carriage with respect to said second guide means; first retainer means for fixing the position of said second guide means with respect to said first guide means; second retainer means for fixing the position of said carriage with respect to said second guide means, said first and said second retainer means fixing the position of said carriage with respect to the base; an echosignal sensor carried by said carriage; a swivel head, said swivel head including a sleeve angularly displaceable with respect to said carriage for supporting said echosignal sensor and for holding said echosignal sensor in contact with the patient'"'"'s body, said sleeve allowing said echosignal sensor to be positioned in one of several monitoring positions while the position of said carriage is fixed with respect to said base wherein the swivel head incorporates a hemispherical case with a flat base mounted on the carriage and said hemispherical case defining a through opening in a central portion thereof for said sleeve and the swivel head further including two partly spherical members carrying said sleeve with one partly spherical member contacting the hemispherical case from the outside and the other partly spherical member contacting the hemispherical case from the inside; means for mounting said members to allow said members to be moved together and apart so that when said members are moved apart, said members can be swivelled along with the sleeve to an angle with respect to the common point to be examined, and when said members are moved together, said members and the sleeve are fixedly rigidly in position; and a plurality of sensors of electric signals carried by and electrically insulated from said base and positionable in contact with the patient'"'"'s body. - View Dependent Claims (7, 8)
