a diagram of an exemplary system 100 in accordance with an embodiment of the present invention is shown in fig1 . for the following discussion , reference will be made to fig1 and 3 , and as necessary , attention will be drawn to a particular figure . fig1 is a view in partial section of a collection cartridge 102 disengaged from a collection device 104 . fig2 is a view of the removable cartridge 102 engaged with the collection device 104 of fig1 and fig3 is a view of the removable cartridge 102 of fig1 engaged with a hand - held analytical device 106 , each according to an embodiment of the present invention . the system 100 of fig1 preferably includes a disposable cartridge 102 for providing a containment chamber 108 into which fluid samples are placed by a collection device for analysis . as known to those skilled in the art , a collection device 104 such as a syringe or lancet , may be used to safely collect a fluid sample into a device body cavity or passageway . the cartridge 102 is adapted to removably engage the collection device 104 and allow the collection device to collect a fluid sample directly into the containment chamber 108 of the cartridge 102 . once a sample is collected into the cartridge 102 , the cartridge may be removed from the collection device 104 and engaged with a remote analytical device 106 for testing . where the collection device 104 allows shielding or retraction of the collection element , such as a needle or lancet , the cartridge 102 may remain safely engaged with the collection device during testing . it will be noted that the embodiments below include needle and lancet assemblies , however , the apparatus of the present invention works just as well with other collection device assemblies . the containment chamber 108 of the cartridge 102 provides contact between collected fluid samples within the chamber and sensory apparatus , such as miniaturized electrodes and micro - sensors , for executing a series of calibration and diagnostic tests on the sample . the sensory apparatus ( not shown ) is distributed in and around the chamber 108 as known to those skilled in the art , and is electrically coupled to an exposed electrical contact 110 located within a port 112 along the containment chamber wall 114 of the cartridge 102 . the exposed electrical contact 110 is contained within a mechanical coupler 116 as known to those skilled in the art , which is adapted to allow direct physical and electrical coupling of the cartridge 102 and a remote analytical device such as a hand - held analyzer , personal digital assistant ( pda ) or visor ®. alternatively , the cartridge 102 may be coupled with a stand - alone computer workstation , or with any number of existing analyzers , such as those manufactured by the i - stat corporation of princeton , n . j . the electrical contact 110 of cartridge 102 allows the cartridge to engage an input port on a hand - held analytical device and electrically couple the sensory apparatus of the cartridge to a testing and analysis means within the analytical device . once coupled to the cartridge 102 , the analytical device gathers and processes information regarding the contained sample via the sensory apparatus within the containment chamber 108 , and thereafter produces outputs which are displayed on an output mechanism , such as a liquid crystal display ( lcd ), analog display or light emitting diode ( led ) indicator . additional tests on the sample may be directed by activation of user interface mechanisms located on the analytical device . as the cartridge 102 is inexpensive and entirely disposable , upon completion of sample testing the cartridge is removed from the analytical device and disposed of . with reference to the drawings of fig1 and 3 , the cartridge assembly 102 of the embodiment shown comprises a housing 118 having a top and bottom containment wall mechanically coupled to one another in a fashion creating a chamber 108 providing for the capture and containment of a sample substance such as blood , from a collection device 104 . the housing 118 has a distal end 120 with a contaimnent chamber inlet orifice 122 formed therein , the orifice 122 being adapted to engage an outlet port 124 on the sample collection device 104 . as used herein , the term “ proximal ” refers to a location on the housing 118 closest to the person using the device and farthest from the patient in connection with which the device is used . conversely , the term “ distal ” refers to a location on the housing 118 farthest from the person using the device and closest to the patient in connection with which the device is used . the cartridge 102 may be removably coupled with a collection device 104 in a number of methods , such as through a press fit between the outlet port 124 of the collection device 104 and the inlet orifice 122 of the cartridge housing 118 . the press fit mechanism of the collection device 104 removably holds the cartridge 102 firmly in place opposite the inlet port , or proximate end of the collection device 104 , which may hold a collection element such as a needle assembly . the press fit mechanism includes the outlet port 124 having a cylindrical extension 126 and an outlet passageway 128 . the inlet orifice 122 of the housing 118 includes an opening 132 , the inside diameter of which is slightly greater than the outside diameter of the cylindrical extension 126 . to couple the cartridge 102 with the collection device 104 , the collection device cylindrical extension 126 is inserted into the cylindrical opening 132 until the shoulder 130 is brought into contact with the distal end 120 of the housing 118 , indicating a secure fit between collection device 104 and collection cartridge 102 . once the cartridge 102 is properly coupled with the collection device 104 as described above , an inlet passageway 134 creates a path between the containment chamber 108 and the outlet passageway 128 contained within the sample collection device 104 . while engaged , a leak - proof seal is formed between the inlet passageway 134 and the outlet passageway 128 , and a fluid sample is drawn into the containment chamber 108 . the sample may be drawn into the containment chamber 108 in a number of ways , including vacuum created within the chamber 108 or capillary action of the inlet passageway 134 . the location of the press fit between collection device 104 and collection cartridge 102 at the proximal end of the collection device opposite the device needle allows easier and safer collection cartridge insertion and removal . all steps are performed opposite the sharp distal end of the collection device 104 preventing dangers to healthcare professionals who may accidentally or through negligent handling , stick themselves with needles . it will be noted that the embodiment above may use a number of press fit mechanisms to bring the inlet passageway 134 into contact with the outlet passageway 128 allowing sample collection . additionally , an adapter may be used at the outlet port 124 of the collection device 104 to allow the use of a wider range of collection cartridges . for example , collection cartridges by manufacturers such as the i - stat corporation , may be used in place of the collection cartridge 102 described above . the adapter may be used to engage any number of various collection cartridges and allow access between outlet passageway 128 of the collection device 104 and various inlet means employed by each collection cartridge manufacturer . as known by those skilled in the art , a fluid sample may be easily collected by a sample collection device 104 , where the collection device may be a syringe or lancet . the collected fluid sample within the device 104 is placed into contact with the outlet passageway 128 and is communicated to the proximal end of the collection device 104 through the natural capillary action of the passageway . the cartridge 102 , once properly engaged with the collection device 104 as described above and shown in fig2 allows the collection of a portion of the fluid sample from the outlet passageway 128 of the collection device 104 by the containment chamber 108 of the cartridge 102 via the inlet passageway 134 . once the cartridge 102 and the collection device 104 are properly engaged through the press fit mechanism described above , the outlet passageway 128 is brought into alignment and contact with the inlet passageway 134 . the inlet passageway 134 creates a path between the containment chamber 108 and the outlet passageway 128 contained within the sample collection device 104 . while engaged , a leak - proof seal is formed between the inlet passageway 134 and the outlet passageway 128 which allows the capillary action of the passageway 134 to communicate a fluid sample from the outlet passageway 128 . the capillary action of the containment chamber 108 completes the capture of the fluid sample , which is then communicated throughout the chamber . once a sufficient sample is captured and contained within the cartridge 102 , the cartridge may be disengaged from the sample collection device 104 or , where practical to do so as described below , the cartridge may remain coupled to the collection device during testing . the exposed electrical contact 110 is located opposite the distal end 120 of the cartridge 102 thereby allowing the cartridge to remain engaged with the collection device 104 during sample testing with a hand - held analytical device as described below . allowing the cartridge 102 and collection device 104 to remain coupled during testing may require shielding the collection device sharp distal end for safety , needle protection and other reasons obvious to those skilled in the art . existing safety - engineered sharps protection systems include shields that pivot over needles , needles that retract into shields , and shields that move forward relative tot he needle , in order to contain the point of the needle . needle pivoting , shielding or retracting systems and methods for collection devices are widely practiced and are described in numerous documents , such as u . s . pat . no . 6 , 368 , 303 issued to richard caizza , and in u . s . pat . no . 6 , 319 , 232 james kashmer , the entire contents of each being incorporated herein by reference . the cartridge assembly 102 further includes sensory apparatus which surrounds the collected sample within the containment chamber 108 . as can be appreciated by one skilled in the art , the sensory apparatus may consist of a number of miniaturized electrodes and micro - sensors adapted to detect and measure various chemical and physical properties of the sample contained within the chamber 108 . the sensory apparatus is distributed in and around the chamber 108 and inlet passageway 134 of the cartridge 102 and is electrically coupled to the exposed electrical contact 110 located externally along the containment chamber wall 114 opposite the distal end 120 of the cartridge 102 . the exposed electrical contact 110 is contained within a mechanical coupler 116 adapted to allow direct physical and electrical coupling of the cartridge 102 and a like electrical contact and mechanical coupler located on a remote analytical device , such as a hand - held analyzer , personal digital assistant ( pda ) or visor ®, or a stand - alone computer workstation . once within the containment chamber 108 , the sample is subject to extensive analysis through direct and indirect contacts with the sensory apparatus , as directed by the remote analytical device . specifically , sample testing is achieved by engaging the cartridge 102 with the collection device 104 as described above . as noted earlier , an adapter may first be engaged with the collection device to accommodate alternate cartridges where necessary . once engaged with the collection device 104 , a sample is collected by the collection device into the cartridge 102 . the filled cartridge 102 may then be removed from the sample collection device 104 , or where practical to do so as described above , the cartridge may remain coupled to the collection device or adapter during testing . a remote analytical device 106 is then prepared to receive the filled cartridge 102 for testing . as known to those skilled in the art , many interface modules are provided to adapt hand - held devices to multiple uses , such as springboard ® expansion modules for a personal digital assistant ( pda ) or visor ® as shown in fig3 . where required , an interface module 134 is installed on the analytical device 106 which allows engagement with the exposed electrical contact 110 and mechanical coupler 116 of the cartridge 102 . as appreciated by those skilled in the art , the analytical device 106 includes hardware and software adapted to access the sensory apparatus within the cartridge 102 and gather information on the sample contained therein , such as ph , pco 2 , po 2 na + , ca ++ , k + , hematocrit and glucose levels in the sample , in addition to sample temperature measurements . the analytical device may then perform numerous tests , configured by the user , on the sample contained within the containment chamber 108 of the cartridge 102 and display results via an output mechanism , such as a liquid crystal display ( lcd ), analog display or light emitting diode ( led ) indicator on the analytical device . additional tests or property detection may be directed by activation of user interface mechanisms located on the analytical device 106 . upon completion , the cartridge 102 and sample therein , are removed from the analytical device 106 and disposed . the cartridge 102 is fabricated as a sterile , disposable unit , preferably made of an inexpensive plastic , such as polyethylene , polypropylene , polyvinylidene chloride or the like . additionally , sensory apparatus within the cartridge 102 are sufficiently inexpensive to allow single use and disposal . in another embodiment of the present invention , a diagram of an exemplary system 136 in accordance with an embodiment of the present invention is shown in fig4 . fig4 is a view of a collection cartridge 138 disengaged from a collection device 140 . the system 136 preferably

located at the distal end of the device body . in the embodiment shown in fig4 the collection device 140 may be comprised of a handle housing 144 , or a handle - lancet housing combination , including a press fit mechanism 142 . the press fit mechanism 142 holds the cartridge 138 firmly in place within a recessed cartridge chamber 146 formed at the distal end of the collection device housing 144 . the recessed cartridge chamber 146 is comprised of a locking slot or recess located within the handle housing 144 extending from the distal end of the housing to receive and secure the collection cartridge 138 to the collection device 140 . the recessed cartridge chamber 146 is open at the distal end of the collection device , allowing the collection cartridge to position a containment chamber inlet orifice array 148 described below , adjacent to a collection device piercing mechanism also located at the distal end of the collection device 140 ( not shown ). with reference to the drawings
