Problems solved by technology

The existing problem of the infusion pump is that since the infusion pump controls the flow rate and flow rate of the infusion by adjusting the speed of the motor, if the transmission between the motor 2 and the rotating shaft 6 fails, such as slipping, belt detachment, etc. When the peristaltic pump does not rotate or rotates at a very slow speed, it will cause safety problems in infusion and cause medical hazards

Embodiment Construction

[0013] an infusion pump, such as figure 1 As shown, it is the same as the existing infusion pump, including a pump body bracket 1, a motor 2, a driving wheel 3, a belt 4, a driven wheel 5, a rotating shaft 6, and an eccentric wheel 7. The motor 2 drives the driving wheel 3 to rotate, and the driving wheel 3 drives the driven wheel 5 to rotate through the belt 4, and the driven wheel drives the rotating shaft 6 of the peristaltic pump to rotate. The wave-shaped movement pushes the liquid in the infusion tube compressed on the outer surface to flow. The infusion pump is also provided with a control unit, which is used to control the starting, stopping and rotating speed of the motor.

[0014] In this embodiment, a pump jam alarm device is also provided.

[0015] like figure 1 As shown, an electromagnetic rotational speed sensor 8 is also provided on one end of the rotating shaft 6 of the peristaltic pump and the pump body support to detect the rotational speed of the driven r...

Abstract

The invention discloses an infusion pump with an occlusion alarm device, which comprises a pump body bracket, a peristaltic pump installed on the pump body bracket, a motor for driving the peristaltic pump and an occlusion alarm device, wherein the occlusion alarm device comprises a sensor and a signal processing module, and the sensor is used for detecting the rotation speed signals of the peristaltic pump and outputting the rotation speed signals to the signal processing module; and the sensor is installed on one end surface of the rotating shaft of the peristaltic pump. By arranging the occlusion alarm device, the invention can detect the rotating condition of the peristaltic pump, and can send out alarm signals in time when the peristaltic pump stalls or the rotation speed of the peristaltic pump drops due to the belt creep or fracture or other causes, thereby reducing the potential safety hazard in the transfusion process.

Description

technical field [0001] The invention relates to a medical device for introducing a medium into a human body, in particular to an infusion pump. Background technique [0002] The infusion pump is a device for safe and precise control of infusion. The traditional bottle infusion method uses the potential energy of the liquid as power, and it is difficult to control the infusion speed and volume stably for a long time, while the infusion pump can meet the requirements of high-precision and rapid infusion. like figure 1 As shown, a motor 2 is fixed on the pump body bracket 1 of the infusion pump, and the motor 2 drives the driving wheel 3 to rotate, and the driving wheel 3 drives the driven wheel 5 to rotate through the belt 4, thereby driving the rotating shaft 6 of the peristaltic pump to rotate. The outer surfaces of the plurality of eccentric wheels 7 on the 6 form a wave-like movement, thereby pushing the liquid in the infusion tube compressed on the outer surfaces to flo...
