Abstract
Be provided with an indwelling needle device for two indwelling needles, be provided with two indwelling needles, both are by hose connection, and flexible pipe is provided with liquid storage cylinder, and liquid storage cylinder surface is provided with liquid discharge hand-hole; Described indwelling needle, comprises and holds needle handle, draw point and conduit, and one end of draw point is inserted into hand-holdable holds in needle handle, and the other end is enclosed with soft conduit; The flexible pipe of described liquid storage cylinder both sides is respectively established an one-hand clip.This utility model is provided with the indwelling needle device of two indwelling needles, the company's of being provided with indwelling needle, and reasonable in design, can realize Real-time Collection blood or administration; And it is simple to operate, best blood sampling or administering effect can be reached when sampling and time correlation, be suitable for clinical expansion.
Description
Technical field
This utility model relates to a kind of remaining needle, specifically a kind of indwelling needle device being provided with two indwelling needles.
Background technology
Remaining needle has now become the comparatively normal a kind of medical apparatus and instruments used in hospital care work, has the puncture time reduced patient, reduces puncture painful, reduce the advantages such as medical personnel's workload.
Existing indwelling needle device is generally and single-endedly punctures into blood, and the other end is semi-closed blood sampling system.Semi-closed system is in closure state when not taking a blood sample, and is anti-hemostasis-coagulation simultaneously, injects a certain amount of anticoagulant at closing end.When taking a blood sample, by negative pressure system as syringe is outwards drawn blood, forming instantaneous path and obtaining desired blood.In like manner, semi-closed system is also in closure state when not administration; When administration, by positive pressure system as syringe inwardly injects the instantaneous path administration of formation.
The common disadvantage of existing remaining needle is: 1. there is dead volume in semi-closed system, namely in existing remaining needle tube chamber, when blood sampling next time or dosing techniques, can be full of back all the time and operate remaining blood and anticoagulant, this part blood and anticoagulant can impact next step operation.When especially measuring the indexs such as blood drug level, when the blood drug level rising stage, the blood in tube chamber dead volume and anticoagulant can dilute the blood of future time point, cause measured result on the low side; Otherwise then result is higher.This situation can cause acquired results and actual value to depart from, and affects medicine Comprehensive Assessment result.2. if, sampling and time correlation, the physiochemical indice that semi-closed system gathers can not the accurate response actual physiochemical indice situation of time point at that time.If discard dead volume inner blood in advance, workload can be made to strengthen, and a large amount of blood resource can be wasted.
Utility model content
This utility model object is the deficiency for solving the problems of the technologies described above, a kind of indwelling needle device being provided with two indwelling needles is provided, structure is simpler, reasonable in design, Real-time Collection blood or administration can be realized, it is simple to operate, at blood sampling or the administering effect of sampling with can reach the best when time correlation.
This utility model for solving the problems of the technologies described above adopted technical scheme is: a kind of indwelling needle device being provided with two indwelling needles, be provided with two indwelling needles, two indwelling needles are by hose connection, and flexible pipe is provided with liquid storage cylinder, and liquid storage cylinder surface is provided with liquid discharge hand-hole; Described indwelling needle, comprises and holds needle handle, draw point and conduit, and one end of draw point is inserted into hand-holdable holds in needle handle, and the other end is enclosed with soft conduit; The flexible pipe of described liquid storage cylinder both sides is respectively established an one-hand clip.
Described liquid discharge hand-hole is one.
Described liquid discharge hand-hole is provided with syringe.
Described liquid discharge hand-hole is provided with the tube for transfusion connecting infusion bottle.
Described liquid storage cylinder is elasticity instant recovery device.
Beneficial effect is:
This utility model is provided with the indwelling needle device of two indwelling needles, is provided with two indwelling needles, reasonable in design, can realizes Real-time Collection blood or administration; And it is simple to operate, best blood sampling or administering effect can be reached when sampling and time correlation, be suitable for clinical expansion.This utility model remaining needle is provided with two indwelling needles, the blood treatment flow regime when needs collected specimens, solving the defect of prior art---during the blood drug level rising stage, the blood in tube chamber dead volume and anticoagulant can dilute the blood gathered next time, cause surveyed data result on the low side; Otherwise then data result is higher, the progress on possessing skills; Be conducive to the accurate response actual physiochemical indice situation of time point at that time; The workload caused because discarding dead volume inner blood is avoided to increase.
