Description
Technical field
The present invention relates to technical field of medical instruments, especially a kind of for tremulous pulse or venipuncture pressure measurement or quiet clinically
The indwelling puncture needle that arteries and veins transfusion is locking.
Background technology
Need at present patient is carried out arterypuncture pressure measurement or venous transfusion clinically and at tremulous pulse or intravenous inlying catheter,
There are the following problems: 1) owing to arterial vascular tube wall relatively vein is thicker, remaining needle when very distinct issues are arterypunctures
Just place, about 0.5 centimetre, the front end of conduit is formed tapered, easily rives or bifurcated when indwelling needle catheter inserts blood vessel, causes conduit
Cannot successfully insert intra-arterial, cause arterial intubation failure, this be also Arterial puncture intubation clinically difficulty apparently higher than
The main cause of Vein Tube.The repeatedly failure of puncture and intubation, not only significantly affects the flow process of clinical anesthesia work, and this is to spy
It is the most unfavorable not need quickly to set up when invasive monitoring is rescued, and there is potential safety hazard.Due also to repeatedly repeated localised puncture causes many
The damage of place's blood vessel brings misery to patient, and causes the waste of remaining needle consumptive material, too increases the medical expense of patient.2) wear
Pricker, without locking device, is attached tremulous pulse pressure measurement using indwelling puncture needle to carry out arterypuncture success backed off after random puncture needle core
Guan Shi, endarterial blood easily sprays through indwelling needle catheter, causes site of puncture or the blood pollution being around ejected.3) exist
When using common Intravenous Indwelling Needle to puncture arterial intubation, because its conduit is the softest, before going back conduit when indwelling needle catheter is inserted
Easily rolled over after holding the power that is hampered, it is impossible to make conduit insert, make one-time successful puncture rate reduce.4) the most locking dress of venous detaining needle
Putting, during the catheter retaining of non-continuous transfusion, blood also easy reflux causes blood coagulation little clot occur to conduit
Formation causes catheter blockage, endovascular blood clot to may result in the generation of patient's embolism class diseases, bring danger to patient.
Summary of the invention
The technical problem to be solved is to provide a kind of locking artery/vein indwelling puncture needle, and it can solve
Indwelling needle catheter front end is tapered because being mutated into, and makes conduit cause catheter proximal end to rive when inserting, jag, or before making conduit
Section is easily caused, by folding, the problem that arterial intubation is failed.
In order to solve the problems referred to above, the technical scheme is that this locking dynamic/venous indwelling puncture needle includes having
Remaining needle supervisor and the body of needle stand and puncture needle core, be provided with one section of flexible pipe in described needle stand leading portion, before described flexible pipe 1/3
The upper end of section is provided with rotary switch, and the flexible pipe lower end corresponding with described rotary switch is provided with blocking-up post；Described remaining needle is responsible for
Formation cone pipe is tapered into from needle stand connection to injector head；Described needle stand back segment is provided with the fixing of band fixing hole
Seat；Side opening pipe is separated on needle stand after described rotary switch；Described side opening pipe connects Y type tube for transfusion, described Y type tube for transfusion
Side pipe is encapsulated with closing cover, opposite side pipe is encapsulated with calparine cap, is provided with blocking-up folder between Y type tube for transfusion and described needle stand.
In technique scheme, more specifically scheme is it may also is that described fixing seat is butterfly architecture.
Owing to using technique scheme, there is advantages that
1, the inlying catheter front end of the present invention gradually forms tapered, and when being conducive to putting pipe, conduit leading portion meets blood vessel wall or subcutaneous tissue
Time resistance time, conduit leading portion or front end do not easily cause rive, bifurcated, or cause conduit leading portion to be rolled over, conduit can be improved and putting
Fashionable success rate；Solve and formed tapered at the catheter proximal end 0.5～1.0 unexpected angle of centimeters, make conduit make when inserting
One-tenth catheter proximal end is rived, jag, or makes conduit leading portion be rolled over.
2, the present invention by the one of flexible tube base section of flexible pipe position handicapping break post formed one blocking-up lock, both can prevent remaining needle
The arterial blood ejection that when far-end is open, pressure is higher, the venous blood being also beneficial to low pressure flows out, and prevents the blood flowed out dirty
Dye site of puncture or surrounding；It more can be shown especially as arterypuncture the most excellent when locking indwelling needle uses
Gesture.
3, the present invention is when using as venous detaining needle, and lock switch is forward in indwelling needle position, defeated in stopping
When liquid keeps puncture needle to be in indwelling state, closing blocking swtich, blood is back to the blood volume of remaining needle and significantly reduces, more favorably
In reducing venothrombotic formation.
4, present configuration is branched into supervisor and side pipe at the back segment of remaining needle with " Y " structure, and side pipe divides with " Y " structure again
Become two passages, it is simple to as venous transfusion or arterial blood drawing, provide conveniently for clinic.
5, the fixing seat of indwelling needle of the present invention is set to the butterfly wing, and the wing of both sides respectively stays a hole, can be used for suture
Fixing remaining needle, in order to privileged sites fixing for arterial puncture detaining needle, prevents the abjection of remaining needle.
6, present configuration is simple, and programming is reasonable, has taken into account the function of needle of retaining on artery and venous detaining needle, expands
The range of indwelling needle.
