Syringe pump

A syringe pump comprising:

• a housing, a first surface of which is concave and a second surface of which is provided with a through hole;
• a push handle seat provided with a syringe snap which is configured for snapping the syringe on the push handle seat;
• a driving device provided inside the housing to drive a push handle seat to move;
• a processor provided inside the housing to send control orders to drive a push handle seat to move;
• a display device movably connected with the first surface, the display device being configured to be foldable so that when the display device is folded in a direction close to the first surface, the display device can be covered on the first surface to form an accommodation space with the first surface;
• a syringe provided in the accommodation space, the syringe including a barrel and a ram;
• a syringe clip fixedly provided on the first surface for clamping and fixing the syringe;
• a connecting rod, one end of which extends into the through hole and is connected with the driving device, and an other end of which extends out of the through hole and is connected with the push handle seat;
• an infusion tube, one end of which is connected with the barrel and an other end of which is connected with a puncture needle;
• a first pressure sensor fixedly provided on the push handle seat;
• a second pressure sensor attached to a first surface of a membrane piece for detecting a pressure in the infusion tube;
• and
• an alarm device provided inside the housing and electrically connected with the processor;
• wherein
• the processor is implemented for acquiring a pressure value of the first pressure sensor in real time, determining whether the pressure value of the first pressure sensor is smaller than a first pressure threshold;
• and controlling the driving device to stop driving the push handle seat to move if the pressure value of the first pressure sensor is greater than or equal to the first pressure threshold;
• the processor is further implemented for acquiring a pressure value of the second pressure sensor if the pressure value of the first pressure sensor has been determined to be smaller than the first pressure threshold, determining whether the pressure value of the second pressure sensor is smaller than a second pressure threshold;
• and controlling the driving device to stop driving the push handle seat to move if the pressure value of the second pressure sensor is greater than or equal to the second pressure threshold.
