Sensor release mechanism for a meter
View Patent ↗A sensor-dispensing instrument adapted to handle a sensor pack contains sensors and performs a test using one of the sensors. The instrument includes an outer housing and a mechanical mechanism for rotating the sensor pack and ejecting one of the sensors from the sensor pack and through a sensor slot on the housing. The instrument also includes a sensor actuator to engage with a sensor disposed in the sensor slot, and a sensor release that is movable to disengage the sensor actuator from the sensor disposed in the sensor slot and permit the discharge of the sensor. The sensor release activates a sensor release mechanism that has a sensor release aid arm, a mounting block, and a pivot pin. The sensor release aid arm contacts the sensor disposed in the sensor slot to assist removal of the sensor from the sensor slot.
1. A sensor-release system for removing a test sensor from a sensor slot in a sensor-dispensing instrument, the sensor-release system comprising:
a sensor actuator disposed adjacent to the sensor slot in the sensor-dispensing instrument, the sensor actuator being configured to engage with a sensor disposed in the sensor slot;
a sensor-release mechanism having a sensor-release aid arm, a mounting block, and a pivot pin connecting the sensor-release aid arm to the mounting block; and
a sensor release including at least one portion configured to engage the sensor-release aid arm to cause the sensor-release aid arm to rotate about the pivot pin and to contact the sensor disposed in the sensor slot thereby causing the sensor to be removed from the sensor slot.
2. The sensor-release system of claim 1 , wherein the pivot pin connecting the sensor-release aid arm to the mounting block is spring loaded.
3. The sensor-release system of claim 1 , wherein the sensor release includes a button portion that projects outwardly from a surface of an outer housing of the sensor-dispensing instrument.
4. The sensor-release system of claim 3 , wherein the at least one portion of the sensor release is coupled to the button portion of the sensor release such that the at least one portion extends from the button portion towards the sensor-release aid arm.
5. The sensor-release system of claim 1 , wherein the sensor release is configured to be depressed to disengage the sensor actuator from the sensor disposed in the sensor slot.
6. The sensor-release system of claim 1 , wherein the sensor actuator is configured to electrically engage with the sensor disposed in the sensor slot.
7. A method of removing a test sensor from a sensor slot in a sensor-dispensing instrument, the method comprising:
providing a sensor-dispensing instrument including an outer housing, a sensor release, and a sensor-release mechanism, the outer housing having a sensor slot through which the test sensor is disposed to conduct the test, the sensor-release mechanism including a sensor-release aid arm, a mounting block, and a pivot pin connecting the sensor-release aid arm to the mounting block;
activating the sensor-release;
in response to the activating, contacting the sensor-release aid arm with at least one portion of the sensor release;
in response to the contacting, causing the sensor-release aid arm to rotate about the pivot in and to engage the test sensor disposed in the sensor slot; and
causing the sensor to be removed from the sensor slot.
8. The method of claim 7 , wherein the sensor release includes a button portion that projects outwardly from a surface of an outer housing of the sensor-dispensing instrument, and wherein the activating includes depressing the button portion of the sensor release.
9. The method of claim 7 , wherein the at least one portion of the sensor release is coupled to the button portion of the sensor release such that the at least one portion extends from the button portion towards the sensor-release aid arm.
10. The method of claim 7 , further comprising, prior to the activating, electrically engaging the sensor actuator with the test sensor disposed in the sensor slot.
11. The method of claim 7 , further comprising, prior to the activating, spring loading the pivot pin connecting the sensor-release aid arm to the mounting block.
12. A sensor-dispensing instrument for dispensing a plurality of sensors, the sensor-dispensing instrument comprising:
an outer housing having a sensor slot through which one of the sensors is disposed to conduct a test;
an electronics assembly generally disposed in the outer housing, the electronic assembly being configured to perform the test;
a sensor actuator disposed adjacent to the sensor slot in the outer housing, the sensor actuator being configured to engage with the sensor disposed in the sensor slot;
a sensor-release mechanism having a sensor-release aid arm, a mounting block, and a pivot pin connecting the sensor-release aid arm to the mounting block; and
a sensor release including at least one portion configured to engage the sensor-release aid arm to cause the sensor-release aid arm to rotate about the pivot in and to contact the sensor disposed in the sensor slot thereby causing the sensor to be removed from the sensor slot.
13. The sensor-dispensing instrument of claim 12 , wherein the sensor actuator is further configured to connect to electrical contacts on the sensor and to transmit electrical signals between the sensor and the electronics assembly.
14. The sensor-dispensing instrument of claim 12 , wherein the sensor release includes a button portion that projects outwardly from a surface of an outer housing of the sensor-dispensing instrument and wherein the at least one portion of the sensor release is coupled to the button portion of the sensor release such that the at least one portion extends from the button portion towards the sensor-release aid arm.
15. The sensor-dispensing instrument of claim 12 , wherein the sensor actuator is configured to electrically engage with the sensor disposed in the sensor slot.
