Abstract
A blood extraction device (100) and method for withdrawing a controlled number of drops of blood from a patient, in whom there is created an incision of such dimension that blood does not freely flow therefrom. A release unit (160) urges drops of blood to flow from the incision, for example by applying a vacuum, and a disabling unit (145, 146, 170) is coupled to the incision unit for disabling the release unit when a predetermined number of drops of blood have been withdrawn.
Claims14
1-16. (Canceled).
A blood extraction device for withdrawing a quantity of blood from a patient, said blood extraction device comprising:
- an incision unit for creating an incision in the patient;
- a release unit for urging blood drops to flow from said incision;
- and
- a disabling unit coupled to the incision unit for disabling the release unit;
- characterized in that:
- a collecting receptacle is disposed in spaced relationship with the release unit for collecting discrete drops of blood that freely fall thereon;
- and
- the disabling unit is adapted to disable the release unit when a predetermined number of discrete drops of blood have been withdrawn.
A method for withdrawing a quantity of blood from a patient, said method comprising:
- creating an incision in the patient;
- urging blood drops to flow from said incision;
- and
- inhibiting blood flow;
- in that:
- blood flows from the incision and falls onto a collection receptacle disposed in spaced relationship with the release unit for collecting discrete drops of blood that freely fall thereon;
- and
- said inhibiting blood flow is performed when a predetermined number of discrete drops of blood have been withdrawn.
A body fluid testing device for performing chemical testing of a body fluid sample, said testing device comprising:
- a chemical test strip holder for receiving a single use chemical test strip on which drops of the fluid are collected;
- a drop counting unit responsive to blood flowing freely onto the chemical test strip for signaling when a predetermined number of discrete drops of body fluid have been applied to said chemical test strip;
- an imaging device for imaging the chemical test result obtained by the chemical test strip;
- and
- an electronic circuit coupled to said imaging device for transmitting data representative of an image of the result to a remote unit.
