Abstract: A belt structure includes a first housing, a second housing, a third housing and a belt. The two ends of the belt are respectively connected to the first housing and the third housing, which can be buckled together quickly. The second housing and the first housing are connected, so that a mechanism for fine tuning the belt can be formed through the gear, the driving element and the resisting element in the first and the second housing.

Abstract: An active squeezing device is used with a drip bag has a drip bag holder and a magnetic pressure assembly. The drip bag holder has a base and a cover mounted pivotally on the base. The magnetic pressure assembly is mounted on the drip bag holder and selectively generates an attractive magnetic force to tightly close the cover on the base to hold and squeeze the drip bag between the base and the cover or generates a repulsive magnetic force to open the cover to release the drip bag. The active squeezing device uses the magnetic force to actively transfuse the liquid medicine or blood in the drip bag to a patient without hanging the drip bag over the patient.
