Abstract
The utility model relates to a duplex-cavity slowrelease liquid medicine infusion device, which belongs to the medical device. The duplex-cavity liquid medicine slowrelease injecting device is composed of a duplex-cavity infusion pump, a highly resilient liquid medicine storage balloon, a duplex-cavity infusion pipe, and the like. The utility model aims at overcoming the defects that the prior chemotherapeutic pump can not finish the single large-dose liquid medicine infusion and the continuous lower-concentration liquid medicine injection. The duplex-cavity slowrelease liquid medicine infusion device is characterized in that two ends of the highly resilient liquid medicine storage balloon are respectively connected with the duplex-cavity infusion pump and the duplex-cavity infusion pipe, when the liquid medicine is infused from the front cavity of the infusion pump, the liquid medicine is firstly infused into the liquid medicine storage balloon, and then the liquid medicine storage balloon inflates and the liquid medicine is gradually infused into the coelomic cavity or the haemal tube through one cavity of the infusion pump under the elastic recoil, thus the continuous lower-concentration liquid medicine infusion is finished; when the liquid medicine is infused from the rear cavity of the infusion pump, the liquid medicine directly flows to the coelomic cavity or the haemal tube through the other cavity of the infusion pipe to finish the single large-dose liquid medicine infusion. The arrangement of an anti-reflux device at the tail end of the duplex-cavity infusion pipe can prevent the blood and the humoral fluid from reflux to the conduit cavity to cause clogging. The utility model has easy manufacturing, low cost, strong practicability and wide market prospect.
