The invention discloses a portable infusion device which is composed of an infusion bag, an infusion pipe, a box body, a spiral spring power device, a feeding device, a speed regulation device and an alarm device. When the portable infusion device works, the tail end of the infusion bag is vertically clamped through rollers on the feeding device, the feeding device is driven by the spiral spring power device to conduct grinding so that the infusion bag can advance to extrude out liquid medicine, and the liquid medicine is conveyed into bodies of patients. The speed regulation device can regulate the advance speed of the feeding device so that the infusion flow can be controlled. When the rollers of the feeding device advance to the head top position of the infusion bag, liquid medicine conveying is completed at the moment, and the alarm device can be triggered to make a sound so that medical staff can be reminded of replacement of the infusion bag in time.
Description
technical field [0001] The invention belongs to a medical transfusion device, in particular to a portable transfusion device. Background technique [0002] At present, the infusion sets in the medical industry are mainly gravity infusion sets. Its working principle is that under the action of atmospheric pressure, the liquid in the bottle flows into the drip funnel along the thinner infusion hose. When the water column pressure of the drip funnel is greater than the venous pressure, the bottle The fluid in the tube flows into the vein along the tube. Its shortcoming is that the infusion bag will be placed on a certain height, is limited by the space, and the speed of infusion cannot be regulated. [0003] In the treatment sites where some accidents occurred, since there is no hanging rod for placing the infusion bag, the medical staff need to hold the infusion bag high with their hands to infuse the patient. , resulting in poor infusion effect, thereby affecting the patien...
