Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the invention provides a technical scheme that:
referring to fig. 1, 12 and 18, an assembly pushing device for an invasive biosensor electrode assembly includes an upper case 1 and a bottom case 2, wherein the inside of the bottom case 2 is connected with a support seat 5 through a second screw pair 02, and the inside of the support seat 5 is clamped with an invasive biosensor electrode assembly 4; the inner part of the upper shell 1 is clamped with an invasive biosensor transmitting assembly 3; the upper shell 1 and the bottom shell 2 are connected through a first thread pair 01; the upper part of the supporting seat 5 is clamped with the upper shell 1 through a guide piece 8; the pitch of the first thread pair 01 is smaller than the pitch of the second thread pair 02;
when unscrewing before implantation, the stress direction of the supporting seat 5 is converted from transverse to longitudinal due to the action of the guide piece 8; because the pitch of the first thread pair 01 is smaller than that of the second thread pair 02, the axial distance of rotation of the first thread pair 01 is smaller than that of the second thread pair 02, when the upper shell 1 and the bottom shell 2 are separated through the rotation of the first thread pair 01, the bottom shell 2 drives the supporting seat 5 to push the upper shell 1 through the second thread pair 02, and therefore the assembly of the invasive biosensor transmitting assembly 3 and the invasive biosensor electrode assembly 4 is achieved.
Alternatively, the pitch of the first thread pair 01 is 4mm and the pitch of the second thread pair 02 is 8mm.
Alternatively, the first thread pair 01 may be a single thread, a double thread, or a multiple thread structure above the double thread; this example is a double thread structure.
Optionally, the lead angle of the first thread pair 01 and the second thread pair 02 is greater than 0 °, which may be 30 °, 45 °, or 60 ° in this embodiment; only if the thread lift angle is larger than 0 degrees, the base can drive the screw rod column to rotate, so that the supporting seat is pushed to move upwards.
According to the embodiment of the disclosure, the assembly of the invasive biosensor electrode assembly and the invasive biosensor emission assembly can be completed only by rotating the bottom shell through double-thread transmission, the ascending height of the supporting seat is controlled by calculating and adjusting the pitch difference between the first thread pair and the second thread pair, and the moving direction of the supporting seat is controlled by the guide piece, so that the bioelectrode can move to a designated position, and the accurate assembly is realized; meanwhile, a user can complete the assembly of the biosensor before implantation by only twisting the bottom shell to separate the bottom shell from the upper shell, and the biosensor is implanted in the body, so that the biosensor is relatively simple and convenient to use and assemble; simultaneously, the upper shell and the bottom shell are connected by adopting a threaded structure, friction force and a connected surface base are increased, relatively tight connection is realized, the false touch prevention effect is better, and the reliability is high.
