A kind of transfusion connector and infusion pipeline and transfusion device provided with the transfusion connectorTechnical field
The present invention relates to medical instruments field, more particularly to a kind of transfusion connector and provided with the defeated of the transfusion connectorLiquid pipeline and transfusion device.
Background technology
Traditional infusion device, as transfusion connector, is punctured into container in infusion vessel provided with exposed body-free transfusion puncture needleLiquid discharges into transfusion device, and nursing staff needs hand-held exposed body-free transfusion puncture needle operation when changing transfusion, easily accidentally injured.
Body-free transfusion puncture needle is smooth because of surface, and adhesive force is low, when inserting infusion vessel, such as because attached on transfusion device and transfusion devicePart is excessive, overweight, easily slips, and forms medical hidden danger；Meanwhile, because puncture needle needs part to be exposed in outside air, easilyIt is contaminated, when contaminated puncture needle punctures into next bottle of transfusion again, decoction can be caused contaminated.As deposited in infusion treatment placeIt is former there is drug resistance to cause a disease（The golden grape ball of such as drug resistance）, or have in same infusion treatment place highly pathogenic pathogenic originalInfectious patients when easily cause nosocomial infection, the time required to increase Case treatment expense and extended treatment, or even jeopardize diseasePeople's life.
Existing body-free transfusion puncture needle is worn substantially provided with hollow pipeline with facilitating decoction water conservancy diversion, but being provided with the transfusion of hollow pipelineThe production cost of pricker is higher, and puncture force needed for the rubber stopper in the infusion vessel supporting with it is larger, it is often more important that itsMore puncture chips can be brought, chip is punctured and is mixed into infusion vessel with decoction and human body formation is endangered.
Nursing staff need to come back when patrolling transfusion condition and observe infusion vessel situation, also need to look squarely observation dropping funnel situation,Increase nursing staff's workload.
General infusion set transfusion can cause blood to defeated when completing because there is pressure differential between woven hose and patient's blood vesselLiquid pipe is flowed back or transfusion inner air tube is entered in patient body by woven hose, gently then causes patient or family members panic, heavy then leadThe people's aggravation that causes a disease forms malpractice.
