Abstract

A body fluid analyte detection device, includes: a transmitter, provided with at least one first fastener part; a bottom case, provided with at least one second fastener part corresponding to the first fastener part, and the bottom case including at least one fixed portion and at least one force-receiving portion. When separating the bottom case and the transmitter, the fixed portion is fixed and a force is applied to the force-receiving portion in one direction, separating the bottom case and the transmitter. The body fluid analyte detection device further includes a sensor connected with the transmitter to transmit the parameter signal; and a battery assembled in the bottom case or in the transmitter. The part holding the battery is the battery portion. A force is applied to the force-receiving portion in only one direction to make the bottom case fail and thereby separating the transmitter and the bottom case, simplifying user action and enhancing user experience.

First claim

The invention claimed is:

1 . A body fluid analyte detection device, comprising:
a transmitter, provided with at least one first fastener part; a bottom case, provided with at least one second fastener part corresponding to the at least one first fastener part, and with the at least one first fastener part and the at least one second fastener part fastening with each other, wherein the transmitter is assembled on the bottom case, and the bottom case comprises at least one fixed portion and at least one force-receiving portion, and when separating the bottom case and the transmitter, the at least one fixed portion is fixed and a force is applied to the at least one force-receiving portion in one direction leading to the bottom case failure, separating at least one pair of the at least one first fastener part and the at least one second fastener part mutually fastened with each other, thus separating the bottom case and the transmitter; a sensor, assembled to the bottom case, wherein the sensor is used to detect an analyte parameter of a body fluid, and the sensor is connected to the transmitter to transmit a parameter signal; and a battery, for powering the transmitter, wherein the battery is assembled in the bottom case or in the transmitter, and a part holding the battery is a battery portion, wherein a bottom board of the bottom case is provided with a window where a sensor unit is assembled, and a part of the sensor is mounted on the sensor unit, and an edge contour shape of the sensor unit and an edge contour shape of the window match each other, an edge of the sensor unit and an edge of the window are embedded into each other and fit together so as to fix the sensor unit to the bottom board, and the sensor is assembled on the bottom case with support of the sensor unit, wherein the sensor unit comprises a main portion and a protrusion protruding from the main portion, the sensor is disposed at the main portion, the window comprises a main hole and a concave portion communicated with the main hole, the main portion is located in the main hole, the protrusion is engaged with the concave portion, and the sensor unit is detachably engaged with the bottom case.

2 . The body fluid analyte detection device of claim 1 , wherein
a part of the bottom case where the transmitter is fastened is the force-receiving portion.

3 . The body fluid analyte detection device of claim 1 , wherein
a side of the bottom case is provided with a convex portion which is the force-receiving portion.

4 . The body fluid analyte detection device of claim 1 , wherein
the battery is provided in the bottom case on which at least one connection hole is provided, and the transmitter is electrically connected to two electrodes of the battery through the connection hole, and the battery portion is the force-receiving portion.

5 . The body fluid analyte detection device of claim 4 , wherein
a sealing ring is provided around the connection hole to seal in an electrical connection position, and when a force is applied to the force-receiving portion, the sealing ring provides an elastic force that facilitates separation of the bottom case and the transmitter.

6 . The body fluid analyte detection device of claim 1 , wherein
a seal member is provided around the sensor to seal in a connection position between the sensor and the transmitter, and when a force is applied to the force-receiving portion, the seal member provides an elastic force that facilitates separation of the bottom case and the transmitter.

7 . The body fluid analyte detection device of claim 3 , wherein
the transmitter is provided with two first fastener parts, and the bottom case is correspondingly provided with two second fastener parts, and in the bottom case, the force-receiving portion and the fixed portion are respectively set on two sides of a connection line l 1 between the two second fastener parts.

8 . The body fluid analyte detection device of claim 7 , wherein
a crease groove is provided on the bottom case at a position corresponding to the connection line l 1 .

9 . The body fluid analyte detection device of claim 7 , wherein
the two second fastener parts are hooks and disposed on a side wall of the bottom case.

10 . The body fluid analyte detection device of claim 7 , wherein
the convex portion is provided on a same side as the two second fastener parts and close to the two second fastener parts.

11 . The body fluid analyte detection device of claim 1 , wherein
the at least one force-receiving portion comprises two force-receiving portions, the bottom case is provided with four second fastener parts, and connection lines between corresponding second fastener parts of the four second fastener parts are l 2 and l 3 , respectively, which divide the bottom case into three parts: one of the force-receiving portions, the fixed portion and an other of the force-receiving portions, in which the two force-receiving portions are located on both sides of the bottom case while the fixed portion is located between the two force-receiving portions.

12 . The body fluid analyte detection device of claim 3 , wherein
the battery is provided inside the transmitter, the bottom case is provided with an assembly hole which is used to assemble the battery portion, and a part of the battery portion is exposed outside the bottom case, and the convex portion is located on one side of the assembly hole, and when a force is applied to the convex portion, the part of the battery portion is used as a supporting portion.

13 . The body fluid analyte detection device of claim 1 , wherein
a failure mode of the bottom case comprises one or more combinations of fracture of a bottom board or a side wall of the bottom case, breakage of the bottom case, breakage of the second fastener part, or plastic deformation of the bottom case.
