Abstract: A biosensor is a sensor strip that is folded to form a base and a cover. The base has sides, a reactive layer and two electrodes. One of the electrodes is mounted longitudinally on the base, extends from the base to the cover and is covered with insulating materials. The other electrode is mounted on the base from an end of the base to the reactive layer. The cover bonds to and is shorter than the base and has a sample notch. The sample notch is formed in one side of the cover, corresponds to the reactive layer and is near the electrode on the reactive layer. A sample reacts thoroughly with the reactive layer because the anode on the cover takes time to transfer electrons therefore accurate test results are obtained.

Abstract: A biosensor is a sensor strip that is folded to form a base and a cover. The base has a reactive layer, two electrodes, a compensating electrode and a variable resistive pad. The reactive layer is formed on the base. The electrodes are formed on the base and connect to the reactive layer to an end of the base. The compensating electrode is formed between the electrodes and is connected to one electrode by the variable resistive pad having an adjustable resistivity to account for manufacturing errors. The cover is shorter than and adhered to the base and has a sample-dropping section corresponding to the reactive layer to allow a liquid sample to be added to the reactive layer. Operators insert the biosensor into the biosensor detector and obtain a correct result without calibrating the biosensor detector so preventing human calibration errors.

Abstract: An ejection device for a biosensor detector has a body that has a front end, an insertion slot formed in the front end, an ejection mount and a resilient element. The ejection mount has a recess with a guide protrusion being mounted near the front end of the body, two button guides being formed in the ejection mount, an ejection button being mounted on the body and adjacent to the insertion slot, two guide tabs and a limit mounted in the recess. The guide tabs are mounted slidably in the button guides to slidably hold the ejection button on the body. The resilient element is mounted in the recess and has a proximal end being mounted on the guide protrusion and a distal end to move the ejection button forward. Therefore, a patient or carer can eject the biosensor conveniently and safely.

Abstract: A connector to receive blood test chips for use with a blood-substance measuring device includes a receptacle, a plug and a wire lead. The receptacle has two ends and a slot. The slot is formed on one end of the receptacle and receives a test chip. The wire lead connects to the other end of the receptacle and the plug. The plug is adapted to be inserted into a corresponding socket in the blood-substance measuring device to electrically connect the test chip to the device.

Abstract: A biosensor is a sensor strip that is folded to form a base and a cover. The base has sides, a reactive layer and two electrodes. The reactive layer is mounted of the base and has a gap. The electrodes are mounted longitudinally on the base respectively near the sides and connect to the reactive layer. The cover bonds to and is shorter than the base and has a sample notch formed in one side of the cover, corresponding to the reactive layer and being near one of the electrodes. Because the sample notch is formed in the side of the cover and blood needs to cross the gap, blood reacts thoroughly with the reactive layer to provide accurate test results.

Abstract: An electric-current biosensor has a support, an electrode film, a conductive film, a bioactivity layer, and an adhesive layer. The support has a first support and a second support with a concave having a testing port therein. The electrode film has a first electrode film disposed on the first support and a second electrode film disposed on the second support. The first electrode film has a positive electrode film and a negative electrode film, which are formed with an interval slit therebetween. The conductive film has a positive and negative conductive films electrically connecting with the positive and negative electrode films, respectively. The bioactivity layer is disposed on the first electrode film and forms an activity area. The activity area covers at least some portions of the positive and negative electrode films. The adhesive layer is disposed between the first and second supports for bonding together.

Abstract: An electric-current biosensor has first and second supports, a pair of positive and negative electrodes on the first supports, an activity area covers the positive and negative electrodes, a pair of testing ports on two sides of the second support, and an electrode film mating with the activity area. The pair of testing ports force the sample to flow into the activity area and stops the sample from flowing outside the support along the surface thereof.

Abstract: An amperometric glucose biosensor comprises a sensing electrode and a reference electrode arranged in a side-by-side parallel configuration on an electrically insulating sheet. A passive cover electrode is placed over the side-by-side sensing electrode and reference electrode so that the active surface of the passive cover electrode opposes the active surfaces of the side-by-side electrodes. Physical contact between the passive covering electrode and the side-by-side electrodes is prevented by insulating spacers. The sensing electrode comprises a conductive graphite track coated with a formulation comprising a redox mediator and enzyme and the reference electrode is a parallel track comprising an Ag/AgCl formulation while the passive cover electrode comprising a conductive graphite track coated with a formulation comprising the same redox mediator as used in the sensing electrode but not including an enzyme.
