Abstract: A displacement sensing device is configured for a peritoneal dialysis system. The peritoneal dialysis system includes a housing and a syringe. The syringe is disposed on the housing and has a push rod. The displacement sensing device includes a guide rod, a probing module, and a resistance scale. The guide rod is coupled to the push rod, and the probing module is disposed in the housing and is fixed at the guide rod. The resistance scale is disposed at a side of the probing module. The probing module is configured to contact the resistance scale to obtain a resistance value of the resistance scale and determine a displacement magnitude of the push rod. In addition, a peritoneal dialysis system is also mentioned.

Abstract: A medical injection and suction device includes: a housing that encloses a driving motor; a syringe mount disposed on a wall of an upper side of the housing; a plurality of valves disposed on the wall of the upper side of the housing and on a side of the syringe mount; a slider that moves toward or away from the housing and is disposed on a lateral side of the housing; a driving rod connected to the slider; and at least one slide rod. The driving rod extends through a wall of the lateral side of the housing. An end of the driving rod is connected to the driving motor. The driving motor drives the driving rod to move the slider. An end of the at least one slide rod is connected to the wall of the lateral side of the housing. The slider is disposed in a slidable manner on the slide rod.

Abstract: A peritoneal dialysis device includes: a dialysate catheter that is connected at a first end to a dialysate container connector and at a second to a four-way joint; an injection catheter that is connected at a first end to an injection catheter connector and at a second end to the four-way joint; a waste fluid catheter that is connected at a first end to a waste fluid container connector and at a second end to the four-way joint; and a syringe catheter that is connected at a first end to a syringe and at a second end to the four-way joint.
