## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The presently disclosed subject matter claims priority and is related to U.S. Provisional Patent Application No. 61/772,705, entitled “Finger Guide for Testing Blood Glucose and Associated Methods,” filed on Mar. 5, 2013; the entire disclosure of which is incorporated herein by reference.


TECHNICAL FIELD
The presently disclosed subject matter relates generally to mechanisms for testing blood glucose levels and more particularly to a finger guide system for testing blood glucose and associated methods.
BACKGROUND
A blood glucose test measures the amount of a certain type of sugar, called glucose, in a person's blood. The test can be done at home or anywhere using a small portable device called a blood glucose meter. Testing blood sugar at home is often called home blood sugar monitoring or self-testing. The traditional method of testing blood sugar involves pricking the person's finger with a lancing device (or lancet—a small, sharp needle) to produce a blood droplet, putting the blood droplet on a test strip, and/or then placing the test strip into a glucose meter that displays the person's blood sugar level.
For many people the steps of performing the blood glucose test are seemingly simple. For others, however, this process can be difficult or, at best, challenging. For example, individuals with visual impairment, neurological disorders, and/or tremors may have difficulty using the glucose lancing device and properly placing the blood sample at the correct area on the test strip for accurate blood glucose testing. Accordingly, an apparatus and method for performing these required blood tests is needed that mitigates one or more of the difficulties discussed above.
SUMMARY
In one embodiment, a blood glucose testing system is provided. The blood glucose testing system may include a finger guide and a glucose meter coupler. In some embodiments, the finger guide may include a finger guide body, a finger guide sleeve, and a finger guide opening within the finger guide sleeve. Additionally, the glucose meter coupler may include a locking mechanism configured to attach the glucose meter coupler to a glucose meter. In some embodiments, the glucose meter coupler may also include a battery cover portion configured to replace the battery cover of a glucose meter and, using the locking mechanism, couple to the glucose meter in the same manner as the battery cover.
The glucose meter coupler may also include a coupling feature configured to mate with the finger guide opening of the finger guide sleeve. In some embodiments, an opening is provided in the coupling feature to allow a test strip to pass from a test strip receptacle on the glucose meter to a subject's finger positioned within the finger guide. In certain other embodiments, alignment features may be included within the finger guide opening and on the coupling feature to ensure that the glucose meter coupler and finger guide are desirably aligned during use.
In operation, the blood glucose testing system may be used in some embodiments by providing a standard glucose meter, replacing the battery cover of the meter with the glucose meter coupler, and inserting a test strip in the test strip receptacle of the meter. Thereafter, the finger guide may be secured to a subject's finger, and the finger may then be pricked by inserting a lancing device into the finger guide opening of the finger guide sleeve. After removing the lancing device, the coupling feature of the glucose meter coupler may be pressed into the finger guide opening, thereby enabling the test strip to contact a blood droplet left behind after removal of the lancing device and further enabling the meter to calculate and display a blood glucose level.

The operation of blood glucose testing system 100 can be summarized as follows. With reference to FIG. 1 through FIG. 12, the subject of the blood glucose test and/or a caretaker of the subject of the blood glucose test slides finger guide 110 onto one of the subject's fingers and optionally secures finger guide 110 to the finger using finger guide strap 124. Finger guide 110 is positioned with line of sight through opening 116 of finger guide sleeve 114 to the subject's skin. Subsequently, lancing device 170 is inserted into finger guide sleeve 114 of finger guide 110 (see FIG. 2) and the subject's finger is pricked in order to generate a blood droplet. Lancing device 170 is then removed from finger guide 110. A test strip 160 may then be inserted through opening 150 of coupling feature 146 of glucose meter coupler 140 thereby installing the test strip 160 into test strip receptacle 136 of glucose meter 130, as shown in FIG. 6. Then, coupling feature 146 of glucose meter coupler 140 is press-fitted into finger guide sleeve 114 of finger guide 110, as shown in FIG. 12. Thereby coming into contact with the previously generated blood sample and allowing for a reading of the subject's blood sugar level to be generated and displayed on glucose meter 130.
FIG. 13 illustrates a flow diagram of an example of a method 1300 of retrofitting glucose meter 130 with glucose meter coupler 140. Method 1300 may include, but is not limited to, the following steps.
At a step 1310, a standard glucose meter is provided and the battery cover is removed. For example, glucose meter 130 is provided and its original equipment battery cover at battery compartment 134 is removed, as shown in FIG. 8.
At a step 1315, a glucose meter coupler 140 with features that substantially correspond to the features of the original battery cover of the standard glucose meter is provided. Then, the glucose meter coupler 140 is installed on the standard glucose meter in place of its original battery cover. For example, the battery cover 142 and locking mechanism 148—portion of glucose meter coupler 140 is installed at battery compartment 134 of glucose meter 130, as shown in FIG. 6.
FIG. 14 illustrates a flow diagram of an example of a method 1400 of using blood glucose testing system 100. Method 1400 may include, but is not limited to, the following steps.
At a step 1410, test strip 160 is inserted through opening 150 in coupling feature 146 of glucose meter coupler 140 and test strip 160 is installed into test strip receptacle 136 of glucose meter 130.
At a step 1415, finger guide 110 is secured onto the subject's finger. For example, the subject of the blood glucose test and/or a caretaker of the subject of the blood glucose test slides finger guide 110 onto the subject's finger and secures finger guide 110 using finger guide strap 124. Finger guide 110 is positioned with line of sight to the subject's skin through opening 116 of finger guide sleeve 114.
At a step 1420, lancing device 170 is inserted into finger guide 110 and the subject's finger is pricked. For example, lancing device 170 is inserted into opening 116 of finger guide sleeve 114 of finger guide 110 and the subject's finger is pricked in order to generate a blood droplet.
At a step 1425, lancing device 170 is removed from finger guide 110, leaving a blood droplet behind. Namely, lancing device 170 is removed from opening 116 of finger guide sleeve 114 of finger guide 110. A blood droplet is left behind on the subject's finger. The blood droplet is in a certain location with respect to finger guide sleeve 114 of finger guide 110.
At a step 1430, coupling feature 146 of glucose meter coupler 140 is press-fitted into finger guide sleeve 114 of finger guide 110 such that test strip 160 contacts blood droplet on subject's finger. Namely, because the blood droplet that was created using lancing device 170 in step 1425 is in a certain location with respect to finger guide sleeve 114, the test strip 160 protruding from coupling feature 146 will contact the same location on subject's finger because it is guided by the same finger guide sleeve 114.
At a step 1435, glucose meter coupler 140 of glucose meter 130 is removed from finger guide sleeve 114 of finger guide 110. Then, finger guide 110 is removed from the subject's finger.
At a step 1440, the blood glucose level is read from the display of glucose meter 130.
FIG. 15 illustrates a flow diagram of an example of a method 1500 of operating blood glucose testing system 100 according to a simplest configuration. Method 1500 may include, but is not limited to, the following steps.
At a step 1510, the lancing device is guided to a spot on the subject's finger for producing a blood droplet. For example, by inserting lancing device 170 into finger guide sleeve 114 of finger guide 110, lancing device 170 is guided to a spot on the subject's finger for producing a blood droplet.
At a step 1515, the test strip in the glucose meter is guided to the same spot on the subject's finger for collecting the blood sample. For example, by inserting coupling feature 146 of glucose meter coupler 140 into finger guide sleeve 114 of finger guide 110, test strip 160, which is protruding from coupling feature 146, is guided to the same spot on the subject's finger to which the lancing device 170 was guided in step 1510, and the blood sample is tested.
In summary, blood glucose testing system 100 and methods 1300, 1400, and 1500 may be used to guide a lancing device, such as lancing device 170, to a spot on the subject's finger for producing a blood droplet, and subsequently guide a test strip, such as test strip 160, in a glucose meter, such as glucose meter 130, to the same spot on the subject's finger for collecting the blood sample. Accordingly, blood glucose testing system 100 and methods 1300, 1400, and 1500 may be used to ensure a successful blood glucose test for any individual, but in particular those who might otherwise have difficulty performing the steps of the blood glucose test, such as, but not limited to, those individuals having visual impairment, neurological disorders, and/or tremors.
