A kind of transfusion connector and infusion pipeline and transfusion device provided with the transfusion connectorTechnical field
Medical instruments field is the utility model is related to, more particularly to a kind of transfusion connector and provided with the transfusion connectorInfusion pipeline and transfusion device.
Background technology
Traditional infusion device is provided with exposed body-free transfusion puncture needle as transfusion connector, punctures into container in infusion vesselLiquid discharges into transfusion device, and nursing staff need to hold exposed body-free transfusion puncture needle operation when changing and infusing, easily accidentally injure.
For body-free transfusion puncture needle because surface is smooth, adhesive force is low, when inserting infusion vessel, such as because attached on transfusion device and transfusion devicePart is excessive, overweight, easily slips, 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（Such as drug resistance golden staphylococci）, or have highly pathogenic cause a disease in same infusion treatment placeNosocomial infection is easily caused during the infectious patients of original, the time required to increasing Case treatment expense and extended treatment, or even is jeopardizedPatients ' lives.
Existing body-free transfusion puncture needle is substantially provided with hollow pipeline to facilitate decoction water conservancy diversion, but the transfusion provided with hollow pipeline is wornThe 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 mixes to form human body with decoction into infusion vessel and endanger.
Decoction can mix with decoction, in decoction during lower section transfusion catheter is flowed to again by dropping funnel because of gasBubble phenomenon is formed, jeopardizes medical safety.Operating personnel are inverted or extruded dropping funnel typically after fluid path is infused in connection, make decoctionInto in dropping funnel, dropping funnel is returned into normal operating condition rapidly again after the liquid of half or so is filled with dropping funnel, to reduceBubble produces.Generally, the tube wall of transfusion catheter can still adsorb a small amount of bubble, and operating personnel need to use finger attack or pinchingTransfusion catheter, to exclude bubble.
Nursing staff need to come back when patrolling transfusion condition observes infusion vessel situation, also needs to look squarely observation dropping funnel situation,Increase nursing staff's workload.
