Embodiment Construction

[0037] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] The present invention provides a syringe pump. In the first embodiment of the syringe pump of the present invention, the syringe pump includes a frame, a driving device, a slider assembly and a reference plate, the driving device and the slider assembly are connected to the frame, and the driving device Drive the slider assembly to move back and forth, the slider assembly is provided with a magnet block, and the side of the reference plate facing the magnet block is provided with a plurality of Hall elements arranged in an array to detect the position of the slider assembly relative to the reference plate.

[0039] The position of the Hall element on the reference board has a corresponding relationship with the position during the sliding process of the slider assembly, and each Hall element can be numbered, and...

Abstract

The invention discloses a position detection method of an injection pump sliding block. The method comprises the following steps: according to a preset function relationship between output voltage and relative distance, acquiring relative distances corresponding to output voltages of various Hall elements, wherein the relative distances mean distances between the Hall elements and a magnetic block; comparing and selecting the Hall element which keeps the minimum relative distance with the magnetic block, and using the Hall element as a reference Hall element; and according to the positional information of the reference Hall element on a reference board, acquiring the position of an injection pump sliding block component relative to the reference board. According to the invention, real-time detection on the position of the injection pump sliding block is achieved by virtue of the Hall elements and the magnetic block which are stable in performance and relatively low in cost, so that the completion of an injection task of an injector is detected in real time; and in the case of failure of the injection pump or residual dosage in the injector is insufficient, the injection pump is capable of raising alarm timely so as to inform doctors to avoid the occurrence of medical accidents.

Description

technical field [0001] The invention relates to the technical field of medical device control, in particular to a method and device for detecting the position of a syringe pump and a slide block of the syringe pump. Background technique [0002] At present, the commonly used medical injection pumps at home and abroad mainly include a screw rod and a slider connected to the screw rod. The motor drives the screw rod to rotate to drive the slider to move back and forth on the screw rod, so that the slider can push the syringe head through the transmission device. However, during the use of the syringe pump, the position of the slider of the syringe pump cannot be detected in real time, so that the completion of the syringe injection task cannot be detected in real time. When the remaining dose is insufficient, the medical staff cannot be notified in time, which may easily lead to medical accidents. Contents of the invention [0003] The main purpose of the present invention ...
