Abstract

The invention provides a multi-cavity infusion bag capable of being zoned and automatically changing medicines conveniently. The infusion bag comprises an infusion bag main body (1), a bag cavity bottom cover (2), a rotary outlet transformation device (3) and a liquid pipe (4), wherein the infusion bag main body (1) is a plastic bag which is used for storing medicine liquid; a separation film is arranged in the plastic bag, so that a cavity body is uniformly divided into at least two parts; at least two liquid filling ports (5) are formed in the top of the cavity body; the bag cavity bottom cover (2) is in threaded connection to an opening in the bottom of the infusion bag main body (1); at least two fan-shaped openings, which correspondingly communicate a plurality of cavity zones, are formed in the bottom of the bag cavity bottom cover (3); the rotary outlet transformation device (3) is a cake-shaped structural body; a fan-shaped opening is formed in the cake; and the fan-shaped opening is not greater than the fan-shaped openings in the bag cavity bottom cover (2) in radius and radian. The infusion bag is quite simple and convenient to conduct a liquid changing operation, which can be automatically operated by a patient and family members thereof, without the participation of professional nursing personnel; and the infusion bag is low in cost and broad in application scope.

Description

technical field [0001] The invention relates to the field of clinical medical care, in particular to a multi-chamber infusion bag which can be partitioned and is convenient for changing medicines by itself. Background technique [0002] Infusion is widely used in the field of clinical medical care as a medical method. At present, infusion bags with a single inner cavity are generally used for infusion, and there are several disadvantages: first, if a variety of liquids need to be infused, it is necessary to pull out the needle and replace the infusion bag, which is troublesome; second, when multiple bags are infused , need to pull out the needle multiple times, increase the exposure time of the needle in the air, and increase the chance of bacterial infection; third, all the needle pulling and bag changing processes require the participation of professional nurses. The amount is huge, and patients and their families are constantly consuming patience while waiting for the ba...

Problems solved by technology

At present, infusion bags with a single inner cavity are generally used for infusion, and there are several disadvantages: first, if a variety of liquids need to be infused, it is necessary to pull out the needle and replace the infusion bag, which is troublesome; second, when multiple bags are infused , need to pull out the needle multiple times, increase the exposure time of the needle in the air, and increase the chance of bacterial infection; third, all the needle pulling and bag changing processes require the participation of professional nurses. The volume is huge, and patients and their families are constantly consuming patience while waiting for the bag replacement process, and conflicts and conflicts occur from time to time, which is not conducive to building a harmonious doctor-patient relationship

Chinese patent document CN201310421828.x discloses a multi-chamber infusion bag. Its disadvantages are that the design of the valves between the chambers is complicated, the cost is high, and the volume of the third chamber is quite different from that of the first and second chambers. To limit the scope of application in clinical infusion, Chinese patent document CN201410159714.7 discloses a large-capacity multi-chamber infusion bag. The disadvantage is that when changing the bag, the patient or his family members still need to call the nurse, and the nurse completes this simple operation. , resulting in a serious waste of labor without reducing the risk of infection
