Apparatus for taking blood samples from a patient
First Claim
1. A blood drawing device for use with a blood receptacle assembly including a first part and a second part, blood from a patient passing through the first part into the second part for collection therein, the blood drawing device comprising:
- a base;
a means secured to the base for securing the first part of the blood receptacle assembly;
a means secured to the base for grasping the second part of the blood receptacle assembly;
a means secured to the base for moving the second part into engagement with the first part for collection of blood within the second part; and
a means for manipulating the means for grasping and for manipulating the means for moving, the means for manipulating including a lever actuatable between a first position and a second position, movement of the manipulating means from the first position to the second position causing the means for grasping to clamp the second part of the blood receptacle assembly.

Abstract
A device for use with conventional blood receptacle assemblies provides increased safety and stability for blood collecting operations. The blood drawing device includes a holding element for securing a blood collecting assembly and a clamping mechanism for clamping a blood sampling tube. A sliding mechanism is provided for sliding the blood sampling tube into engagement with the blood collecting assembly. In an alternative embodiment, the blood drawing device may be configured to include a carriage assembly moveably attached to a base and holding a plurality of blood tubes for blood collection. A servo motor moves the carriage assembly relative to the base. A mechanism reciprocates the blood tube between a first and second position such that movement of the tube causes the tube to engage a needle inside the blood collecting assembly. The device may further include sensors for detecting the fill level of the tube and a sensor that detects the insertion of the tube into the opening of the carriage assembly to activate the servo motor to reciprocally move the tube.
