Embodiment Construction

[0020] Preferred embodiments of the invention will be better understood with reference to the drawings, wherein like reference numerals indicate identical or functionally similar elements. It will be readily appreciated that the components of the present invention may be arranged and designed in many different configurations, as generally described and shown in the drawings. Accordingly, the following more detailed description is not intended to limit the scope of the invention as claimed, but is merely representative of preferred embodiments of the invention, as shown in the accompanying drawings.

[0021] Refer below figure 1 , which shows an extravascular system 20 for which a blood sampling device 42 may be used. It should be appreciated that blood sampling device 42 is not limited to use with these example extravascular systems, but may be used with other extravascular systems, ranging from a single needle to more complex extravascular devices. In some constructions, bl...

Abstract

An extravascular system is disclosed. The system includes a body, a septum, a septum activator, and a blood sampling device. The body has and inner lumen extending therethrough. The septum is disposed within the inner lumen. The septum activator is disposed within the inner lumen proximal the septum. The septum activator has an inner passage extending therethrough. The blood sampling device has a tube that is longer than a length of the septum activator and has a width less than or equal to a width of the inner passage of the septum activator. An interior of the tube is in fluid communication with a reservoir within the blood sampling device. A vent is in fluid communication with the reservoir. The vent passes air but not blood therethrough.

Description

Background technique [0001] The present invention relates to ventilation and blood sampling procedures through vascular access devices. Blood sampling is a common health care procedure that involves drawing at least one blood sample from a patient. Blood samples are typically obtained from hospitalized, home care, emergency room patients by finger stick, heel puncture, or venipuncture. Once collected, the blood sample is analyzed through one or more blood test level devices. [0002] Blood tests will determine the patient's physiological and biochemical status, such as disease, mineral content, drug effects, and organ function. Blood tests may be performed in a laboratory some distance away from the patient's location, or at a point-of-care close to the patient's location. An example of a point-of-care blood test is the routine testing of a patient's blood glucose level, which involves drawing blood via a finger prick and mechanically collecting the blood into a diagnostic ...
