Embodiment Construction

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] figure 1 Schematically shows the structure of the syringe near-empty or empty detection mechanism according to the embodiment of the present invention. As shown in the figure, the nearly empty syringe detection mechanism according to the embodiment of the present invention includes: a motor (not shown separately in the figure), used to drive the syringe 5; a transmission device, connected with the motor, and converting the rotation of the motor into Linear motion; injecting part 6, connected with the transmission device; syringe 5, connected with injecting part 6, for example, fixed on the injecting part 6; sensor 2, can be arranged on the part that is relatively fixed on the ground, for example, be arranged on On the mounting plate 1, the position of the injecting part 6 is detected and a corresponding signal is sent out. S...

Abstract

The invention provides an injector nearly-empty already-empty detection mechanism. The mechanism comprises a motor for driving an injector, a driving device which is connected with the motor and transforms the rotation of the motor into linear motion, a push injection component which is connected with the driving device, the injector which is connected with the push injection component, a sensor for detecting the position of the push injection component and sending corresponding signals, a processor which is electrically connected with the sensor, receives the corresponding signals and sends corresponding commands, and an alarm which is electrically connected with the processor and receives the corresponding commands to alarm or not alarm. The motor is electrically connected with the processor and runs or stops running according to the corresponding commands. The invention also provides an injector nearly-empty already-empty detection method. The injector nearly-empty already-empty detection mechanism has a simple structure, and the detection method has high efficiency and is convenient to implement. The mechanism is favorable for prolonging the service life of an injection pump, improving the utilization rate of injection solution in the injector and reducing waste.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a near-empty and empty detection mechanism and method for a syringe. Background technique [0002] Medical syringe pumps are devices that directly inject medicinal liquid into the patient's body, and have high requirements for safety and reliability. When the syringe of the syringe pump is nearly empty, it needs to be reminded that the syringe is almost empty in time, so that the user can handle it in time. If the near-empty and empty alarm is inaccurate, there will be early and delayed alarms. If the syringe is empty, the alarm will be issued in advance, that is, the alarm will be issued before the syringe reaches the zero mark, and the liquid medicine will be left to cause waste of liquid medicine. If the syringe is empty, the alarm will be issued. Hysteresis, that is, the syringe has reached the zero scale without an alarm, which will cause damage to the transmission mechanism ...
