Abstract
A fluid jet blood sampling system and method for obtaining a blood sample from a patient, utilizes a short duration fluid jet from a disposable jet nozzle to perforate at least the epidermis of the skin and to break at least one blood vessel, thereby allowing a quantity of blood to accumulate on the skin surface. A cowling prevents contamination of the local environment with excess fluid, blood, etc. A drying unit may be provided to remove excess fluid, blood, etc. from the skin within the cowling. A sample of blood may be transferred to a test strip, or a collection unit may be used to collect and contain a blood sample from the mammal.
