Repair of Mindray Brand Syringe Pump Type Benfusion SP1

Syringe pump is a tool used to inject medicinal liquids into the human body with high precision using millimeters per hour (ml/h). The Mindray brand syringe pump type Benefusion SP1 had a fatal damage condition because the system experienced a system failure, so it could not function properly. The syringe pump cannot detect the syringe size that has been set because the control system does not work. Repair of the syringe pump was carried out by measuring using a multimeter at the specified measurement point. The syringe pump was successfully repaired by replacing the potentiometer component. After making recommendations, the flowrate and occlusion function tests were carried out. From the results of the flowrate function test, the percentage values were obtained, namely 10ml/h= 3.48%, 50ml/h= 1.19%, 100ml/h= 3.48%. and with occlusion experiments wiht a setting point of 100ml/h, an average value of 523mmHg or 10.113251 psi was easily obtained. From the results above it can be concluded that the tool is still suitable for use because it is still within the tolerance limit of 10% so that the tool can be used again.
