Abstract

Can the remaining needle of Real-time Collection blood or administration, comprise remaining needle body, be provided with two indwelling needles connected by extension tube, extension tube is provided with storage haemocoele and peristaltic pump; Described storage haemocoele is elasticity instant recovery device, which is provided with blood sampling hole; Hole is connected with automatic sampler in blood sampling; Described peristaltic pump is connected with power supply by electric lead, and electric lead is provided with switch.This utility model can the remaining needle of Real-time Collection blood or administration, 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

A kind of can the remaining needle of Real-time Collection blood or administration
Technical field
This utility model relates to a kind of medical apparatus and instruments, a kind of specifically can the remaining needle of Real-time Collection blood or administration.
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.If 2 sampling and time correlations, 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, there is provided a kind of can the remaining needle of Real-time Collection blood or administration, 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, improves the accuracy detecting data.
This utility model for solving the problems of the technologies described above adopted technical scheme is: a kind of can the remaining needle of Real-time Collection blood or administration, comprise remaining needle body, be provided with two indwelling needles connected by extension tube, extension tube is provided with storage haemocoele and peristaltic pump; Described storage haemocoele is elasticity instant recovery device, which is provided with blood sampling hole; Hole is connected with automatic sampler in blood sampling; Described peristaltic pump is connected with power supply by electric lead, and electric lead is provided with switch.
Described blood sampling hole is 1.
Described indwelling needle, comprises draw point, needle handle and conduit; One end of draw point is inserted in hand-holdable needle handle, and the other end is enclosed with soft conduit.
Described extension tube is respectively established an one-hand clip.
Beneficial effect is:
This utility model can the remaining needle of Real-time Collection blood or administration, 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.This utility model remaining needle is provided with two indwelling needles, the blood treatment flow regime when needs collected specimens, solve technological deficiency of the prior art, namely during the blood drug level rising stage, 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 accurate response time point physiochemical indice practical situation at that time; The workload caused because discarding dead volume is avoided to increase.
Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model can realize the remaining needle of Real-time Collection blood or administration;
In figure, labelling is: 1, indwelling needle, 11, needle handle, 12, draw point, 13, conduit, 2, storage haemocoele, 21, blood sampling hole, 3, automatic sampler, 4, power supply, 41, electric lead, 42, switch, 5, peristaltic pump, 6, extension tube, 61, one-hand clip.
Detailed description of the invention
As shown in Figure 1, a kind of can the remaining needle of Real-time Collection blood or administration, comprise remaining needle body, be provided with two indwelling needles 1 connected by extension tube 6, extension tube 6 is provided with storage haemocoele 2 and peristaltic pump 5; Described storage haemocoele 2 is elasticity instant recovery device, which is provided with blood sampling hole 21; Hole 21 is connected with automatic sampler 3 in blood sampling; Described peristaltic pump 5 is connected with power supply 4 by electric lead 41, and electric lead 41 is provided with switch 42.
Described blood sampling hole 21 is 1.
Described indwelling needle, comprises draw point 12, needle handle 11 and conduit 13; One end of draw point 12 is inserted in hand-holdable needle handle 11, and the other end is enclosed with soft conduit 13.
Described extension tube 6 is respectively established an one-hand clip 61.
This utility model can realize the remaining needle of Real-time Collection blood or administration, when use procedure, hand-held needle handle 11, first the draw point 12 of the wherein indwelling needle 1 of one end is thrust in vein blood vessel at human body distal end against blood flow direction, extracting draw point 12 after hemorrhage makes conduit 13 indwelling in Ink vessel transfusing, then closes this side one-hand clip 61; Then, the indwelling needle 1 of the other end is thrust in vein blood vessel in human body proximal part antegrade blood flow direction, extract draw point 12 after hemorrhage and make conduit 13 indwelling in Ink vessel transfusing, close this side one-hand clip 61.
When needs are taken a blood sample, negative pressure is implemented to storage haemocoele 2, opens both sides one-hand clip 61, make to be full of blood in extension tube 6 and storage haemocoele 2 and air in emptying tube chamber, be now full of blood in whole indwelling needle device and form a blood stream access.Meanwhile, be anti-hemostasis-coagulation, can inject a small amount of anticoagulant in indwelling needle device tube chamber, peristaltic pump 5 can strengthen hemodynamic further, and the similar artificial blood vessel of this path, can utilize automatic sampler 3 to implement real-time blood sampling.When needs administration, the automatic sampler 3 that connects of removing blood sampling hole 21, by infusion bottle directly and blood sampling hole 21 be connected, open the one-hand clip 61 in wherein one end extension tube 6, start to infuse.This remaining needle is easy to operate, be conducive to improving gather the accuracy of blood test results.
