Patent ID: 8524168

Claim:
A device for holding a medical test strip, the device comprising: a receiving casing having an opening for receiving the medical test strip, a guiding portion, at least one guiding track and a first stopping portion protruding from an upper surface of the receiving casing; an ejection base having a cover, at least one thrusting portion downwardly extended from the cover and a pusher beneath the cover, the cover downwardly extending a second stopping portion comprising a guiding groove for sliding against the upper surface of the receiving casing and selectively engaging with the first stopping portion, wherein the guiding groove movably engages with the guiding portion for leading the second stopping portion to slide against the upper surface of the receiving casing; and an elastic member located between the receiving casing and the ejection base, the elastic member comprising at least one spring placed in the guiding track, wherein an ejection mechanism comprising, the pusher corresponding to the opening, the guiding groove corresponding to the guiding portion, and the elastic member together with the thrusting portion corresponding to the guiding track, operates smoothly as the device generates less uneven stresses during operation; wherein when the pusher moves toward the opening by an external force to eject the medical test strip from the opening, the elastic member is compressed and the second stopping portion slides away from the first stopping portion; and when the external force disappears, the second stopping portion slides toward the first stopping portion by a resilient force of the elastic member until the first stopping portion and the second stopping portion are engaged.
