  • Patent number: 8728407
    Abstract: A holding device disposed in a bio-detecting instrument for holding a test strip is provided, wherein the holding device comprises a first casing, a second casing, an ejecting member, and an elastic member. The second casing is assembled with the first casing to form an accommodating space, wherein the sensing terminals are extended into the accommodating space. The ejecting member comprises a push rod configured to be reciprocated in the accommodating space. The elastic member is configured to be compressed by driving the ejecting member to an ejecting position, where the push rod enters the accommodating space and is adapted to push the test strip outward without being contact with the sensing terminals, and the elastic member is configured to be released by drawing the push rod back from the accommodating space to an initial position.

  • Patent number: 8524168
    Abstract: A device for holding a medical test strip is provided. The device comprises a receiving casing having an opening for receiving the medical test strip and a first stopping portion protruding from an upper surface of the receiving casing; an ejection base having a cover and a pusher beneath the cover, the cover downwardly extending a second stopping portion for sliding against the upper surface of the receiving casing; and an elastic member located between the receiving casing and the ejection base. When the pusher moves toward the opening by an external force to eject the test strip from the opening, the elastic member is compressed and the second stopping portion slides away from the first stopping portion. 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.
