Abstract
A device to maintain a user's vein in position includes at least two branches separated by a gap of width greater than the size of the vein. A positioner to position the branches around the vein. The device can additionally includes a heater to heat at least one branch and a controller to control the heater. The device can further include a cooler to cool at least one branch and the controller is configured to activate the cooler.
Core Innovation
The invention relates to a device for puncturing or injection into a user's vein that includes a device to maintain a user's vein in position. The vein is maintained using at least two branches separated by a gap of width greater than a size of the user's vein, and means for rotating the branches and an arm configured to move in translation along three axes position the branches around the user's vein.
The device captures an infrared image of the user's arm using a sensor, and detects a vein in the captured infrared image using a detector. A transmitter transmits a location of the detected vein, and the arm is configured to automatically position the branches around the user's vein being controlled according to the location of the detected vein.
A motor positions an extremity of a needle in the detected vein between the branches. The invention additionally encompasses optional vein-maintenance functions including cooler means for cooling at least one branch, ultraviolet emission directed toward the user's vein, and disinfection means to disinfect. In further variants, ultrasound-based sensing can be used via an ultrasound emitter and an ultrasound imaging sensor to position the needle based on images.
Claims Coverage
The partial content provides one independent claim (clm-00001). It covers a vein puncturing/injection device with three inventive features: vein positioning by rotating branches and a multi-axis arm, infrared vein detection and automatic positioning control, and motorized needle placement between the branches, with dependent refinements for auxiliary maintenance and additional sensing.
Vein positioning with rotating branches and multi-axis translation arm
A device to maintain a user's vein in position, comprising at least two branches separated by a gap of width greater than a size of the user's vein, means for rotating the branches and an arm configured to move in translation along three axes, the means for rotating the branches and to position the branches around the user's vein.
Infrared vein detection, transmission, and automatic branch positioning
A sensor to capture an infrared image of the user's arm; a detector to detect a vein in the captured infrared image; a transmitter to transmit a location of the detected vein; and the arm configured to position automatically the branches around the user's vein being controlled according to the location of the detected vein.
Motorized needle placement between branches based on detected vein location
A needle; and a motor to position an extremity of the needle in the detected vein between the branches.
Across the independent claim, the core coverage combines two spaced branches and a multi-axis arm to maintain vein position, infrared imaging detection with transmission of the vein location for automatic positioning control, and motorized positioning of the needle extremity into the detected vein between the branches. Dependent refinements in the provided content further add cooling, ultraviolet emission, disinfection, and optional ultrasound-based imaging for positioning.
