Abstract

The invention discloses a catheterization length measuring mechanism and medical catheterization simulation equipment. The catheterization length measuring mechanism comprises a case, one or a plurality of first sensing parts and one or a plurality of second sensing parts, wherein a catheterization passage is limited in the case; the catheterization passage is configured to accommodate a simulatedmedical tube; the one or the plurality of first sensing parts are connected with the case; when the plurality of first sensing parts are used, the plurality of first sensing parts are arranged at intervals in the axial direction of the catheterization passage; and when the one or the plurality of second sensing parts are configured to simulate the movement of the medical tube along the catheterization passage, the second sensing part and the first sensing part achieve mutual action. The catheterization length measuring mechanism has the advantages that the control logics are simplified; the production cost is reduced; and the catheterization length measurement reliability is improved.

Description

technical field [0001] The invention relates to the field of medical simulation teaching equipment, in particular to a tube length measuring mechanism and medical tube simulation equipment. Background technique [0002] In the actual medical catheterization process, it is necessary to drive the medical tube to extend into the human body. Therefore, in the simulated catheterization device of the medical education equipment, it is required that the simulated catheterization device can measure the moving distance of the simulated medical tube, so as to make the simulated catheterization process more realistic. In the prior art, the control circuit of the catheter length measuring mechanism set up in medical education is relatively complicated, the cost is high, and the reliability is not high. Contents of the invention [0003] The purpose of the present invention is to provide a tube length measuring mechanism with relatively simple control logic and low cost. [0004] Ano...
