Diagnostic medical device and methods of use thereof

Abstract

A medical device to test bodily fluid, the device comprising a light emitting source, the light emitting source arranged to emit light inside the medical device; a test strip port, the test strip port comprising a test strip port receptacle to receive a test strip; and the light emitting source and the test strip port arranged such that, when the light emitting source emits light, at least a portion of the light emitted from the light emitting source is redirected inside the medical device to provide redirected light inside the medical device, and at least a portion of the redirected light lights the test strip port from inside the medical device in a manner than the redirected light is visible outside the test strip port.

What is claimed is: 
     
         1 . A device, comprising:
 a main body; and   a test module detachably coupled to the main body, the test module including a cover engageable to the main body by engagement of a snap-fit connection and disengageable from the main body by disengagement of the snap-fit connection, wherein the snap-fit connection is engageable by translational motion of the cover relative to the main body, and wherein the snap-fit connection is disengageable by rotational motion of the cover relative to the main body.   
     
     
         2 . The device of  claim 1 , wherein the snap-fit connection is not disengageable by translational motion of the cover relative to the main body. 
     
     
         3 . The device of  claim 1 , wherein the main body comprises a center axis and at least two resilient cantilevered arms, and wherein the at least two resilient cantilevered arms are arranged to move towards and away from the center axis. 
     
     
         4 . The device of  claim 3 , wherein the at least two resilient cantilevered arms are arranged to move towards each other during engagement of the snap-fit connection. 
     
     
         5 . The device of  claim 3 , wherein the at least two resilient cantilevered arms each include at least one engagement tab, wherein the cover includes at least two engagement tab receptacles, and wherein each of the at least two engagement tab receptacles is configured to receive one of the engagement tabs. 
     
     
         6 . A device, comprising:
 a main body; and   a test module detachably coupled to the main body, wherein the test module comprises a cover including a receptacle operable to receive a biasable arm of the main body for coupling the main body and the cover together, and wherein the cover includes a rib engageable within a rib receptacle of the main body to restrict motion of the cover relative to the main body.   
     
     
         7 . The device of  claim 6 , the cover further comprising an engagement tab operable to engage a corresponding engagement tab of the biasable arm to restrict translational motion of the cover away from the main body. 
     
     
         8 . The device of  claim 7 , the engagement tab of the cover comprising a sloped surface operable to bias the biasable arm relative to a center axis of the main body as the engagement tab and the corresponding engagement tab engage one another. 
     
     
         9 . The device of  claim 7 , the corresponding engagement tab of the biasable arm comprising a sloped surface operable to bias the biasable arm relative to a center axis of the main body as the engagement tab and the corresponding engagement tab engage one another. 
     
     
         10 . The device of  claim 9 , the main body further comprising a second biasable arm, wherein the biasable arm and the second biasable arm are operable to move relative to the center axis of the main body when the main body and the cover are coupled together. 
     
     
         11 . The device of  claim 6 , the cover further comprising a test strip receptacle. 
     
     
         12 . The device of  claim 6 , wherein the rib extends from an inner surface of the cover. 
     
     
         13 . The device of  claim 6 , the test module further comprising one or more electronic components and a test strip connector coupled to the cover, the test strip connector operable to receive a test strip. 
     
     
         14 . A handheld electronic device, comprising:
 a main body; and   a test module detachably coupled to the main body, wherein the test module comprises a cover including an engagement tab operable to engage a biasable arm of the main body for securing the main body and the cover together, and wherein the cover includes a rib engageable within a rib receptacle of the main body to restrict motion of the cover and the main body relative to one another.   
     
     
         15 . The handheld electronic device of  claim 14 , the biasable arm comprising a corresponding engagement tab, wherein the engagement tab and the corresponding engagement tab are operable to engage one another to restrict translational motion of the cover relative to the main body. 
     
     
         16 . The handheld electronic device of  claim 15 , the corresponding engagement tab comprising a sloped surface operable to bias the biasable arm relative to a center axis of the main body as the engagement tab and the corresponding engagement tab engage one another. 
     
     
         17 . The handheld electronic device of  claim 16 , the main body further comprising a second biasable arm, wherein the biasable arm and the second biasable arm are operable to move relative to the center axis of the main body when the main body and the cover are coupled together. 
     
     
         18 . The handheld electronic device of  claim 14 , the cover further comprising a test strip receptacle. 
     
     
         19 . The handheld electronic device of  claim 14 , the test module further comprising one or more electronic components coupled to the cover. 
     
     
         20 . The handheld electronic device of  claim 14 , wherein the rib extends from an inner surface of the cover.
