Description
Technical field
It the utility model is related to a kind of arterial puncture needle, specifically a kind of arterial puncture needle with seal wire.
Background technology
Blood pressure is clinical earliest and the most frequently used monitoring index.On Present clinical between commonly used cuff auscultation blood pressure category
Connect pressure testing method, counterweight danger and shock patients and in the case of low temperature and extracorporal circulatory system, then can not be promptly and accurately dynamically anti-
Reflect blood pressure.Due to the needs of emergency medicine, department of cardiovascular surgery and ICU development, direct manometric method is invasive blood pressure（IBP）Into
The Main Means monitored for critically ill patient and capital operation peri-operation period haemodynamics.These fields, all it be unable to do without anesthesia doctor
The participation of teacher, be required for anesthetist by it is accurate, monitor blood pressure in time, understand the state of an illness, participate in even guiding treatment, ensure and suffer from
Person or patient with operation safety, the complication caused to reduction peri-operation period haemodynamics change and case fatality rate have important
Meaning.IBP systems pass through peripheral arterial puncture and intubation, and the pressure in peripheral arterial is passed through into transducer（Pressure sensor）With prison
Instrument connection is surveyed, directly displays out pressure waveform and parameter.Most easy method is connected by pipeline with spring sphygomanometers come anti-
Reflect blood pressure data.IBP can typically monitor arterial pressure（ABP）, central venous pressure（CVP）, pulmonary arterial pressure（PAP）And PLA left atrial pressure
（LAP）.Its measuring principle is：First by arteriopuncture, place a catheter in the intravascular of tested position, external catheter end directly with
Transducer is connected.Because fluid has pressure transmission effect, intravascular pressure will be delivered to outside by the liquid in conduit
Transducer on, so as to obtain the dynamic waveform of intravascular real-time pressure change, by specific calculation method, obtain tested portion
Position vessel retraction pressure (SBP), diastolic pressure (DBP) and mean arterial pressure (MAP).IBP turns into critically ill patient hemodynamic at present
The Main Means of Hygienic monitoring on hands of childhood, it can timely and accurately monitor the blood pressure of patient, and can display waveform.In general,
IBP pressure measurement values are higher by 5 ~ 20mmHg than non -invasivetesting value.
Present ASA is classified conventional line arteriopuncture in patient's art of II grade and the above, but existing arterial puncture needle due to
The position of hand is bad, or local by position, does not fix, can influence normal testing result, sometimes piercing needle tip
It is adherent, testing result can be equally influenceed, there are some patient's blood vessel atherosis, there is patch, luminal stenosis, Arterial puncture intubation meeting
Have any problem.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model proposes a kind of arterial puncture needle with seal wire, including puncture needle
Seat, the puncture needle tubing on Paracentesis needle holder, indwelling base, the indwelling tube on indwelling base, indwelling tube, which is located at, to be worn
In pricker pipe, the external diameter of indwelling tube is equal to the internal diameter for puncturing needle tubing, promotes indwelling base, inwall of the indwelling tube along puncture needle tubing
Slide, in addition to the filament guiding seat in indwelling tube, and the seal wire being connected on filament guiding seat；
The filament guiding seat is hollow tube, and the external diameter of filament guiding seat is equal to the internal diameter of indwelling tube, and the both sides of filament guiding seat, which are provided with, to be slided
Plectrum, the inside of filament guiding seat are provided with seal wire fixed hurdle, and seal wire is fixedly connected on seal wire fixed hurdle；
The middle and upper part both sides for puncturing needle tubing are correspondingly provided with the track window slided up and down for sliding plectrum, the indwelling tube
Middle and upper part both sides also correspond to and be provided with for sliding the track window that slides up and down of plectrum, slide plectrum through the track window for puncturing needle tubing
With the track window of indwelling tube, slided up and down along the track window and the track window of indwelling tube that puncture needle tubing, so as to drive filament guiding seat,
Seal wire fixed hurdle and the seal wire being fixedly connected on seal wire fixed hurdle slide up and down；
The height of the filament guiding seat is more than twice of indwelling tube track window height, and the plectrum that slides is to filament guiding seat
The distance at end, the distance to filament guiding seat lower end are all higher than the height of indwelling tube track window.
The outer end for sliding plectrum is also connected with circular handle.
Beneficial effect：Due to adding seal wire inside indwelling tube, when row arteriopuncture in art, spike pierces patient
Skin reaches patient's artery, and now, slide downward slides plectrum, and so as to which seal wire be stretched out inside indwelling tube, seal wire is deeply suffered from
Person's intra-arterial, now, indwelling tube base is promoted, indwelling tube is inserted in patient's arteries, because the guide effect of seal wire, from
And ensure that indwelling tube gos deep into patient's intra-arterial along seal wire, so as to overcome existing arterial puncture needle due to hand position not
It is good or local by position, do not fix, the problem of influenceing normal detection result, it is adherent to it also avoid piercing needle tip, influences
The problem of testing result, for some patient's blood vessel atherosis, there are patch, luminal stenosis, the utility model moving with seal wire
It is simple to operate that arteries and veins puncture needle puts pipe, puts pipe and is easier.
