Description
Technical field
The utility model is related to a kind of monitoring analysis pin；More particularly to a kind of artery remaining blood gas analysis needle.
Background technology
Clinically, Arterial puncture intubation technology has been widely used, using needle of retaining on artery donor source arterial blood samples,
Enter Mobile state blood gas analysis and arterial pressure monitoring etc., be conducive to dynamic observation and active treatment in art.This technology is main
The long-term skilled operation degree of operator and clinical experience are fixed against, and for the person of lacking experience, operator sees in puncture
During to blood, and force down the dry continuation inserting needle of pin and further insert after indwelling needle tubing, judge indwelling needle tubing whether still in the blood vessels
It is difficult.
Arterial pressure is higher, if after puncturing successfully, it is impossible to which simultaneously position presses artery exactly in time, easily causes artery
Blood sprays from needle tubing tail end, pollutes operating area, or even cause the propagation of iatrogenic disease.
When radial artery detaining tube fails first, radial artery can because stimulate spasm or local hematoma, it is necessary to oppress five minutes with
On again row puncture or change puncture another hand.In this way, the timely progress of influence operation, while bringing more pains of injury to patient.
In document CN204072259U, a kind of artery remaining blood gas analysis needle, including combination pin and inspection section are disclosed.
Observation tube outer surface indicates scope for 0ml~1.0ml, and inspection section internal diameter is 3mm, and observation tube inner surface scribbles anti-coagulants.
In the above documents, during inspection section, nook closing member is extracted to installation detection pipe, outer tube is by arteries and greatly
Gas is connected.In such cases, blood can constantly outbound flow.If for anti-Hemostatic Oral Liquid, then need it is artificial push down blood vessel, to prevent
Hemostatic Oral Liquid outflows.The human hand that so operation needs is more, while the promptness and harmony to operation require higher.
The content of the invention
The purpose of this utility model is to solve during Arterial puncture intubation and blood sampling blood gas analysis, outside blood
The problem of stream, many operation human hands, inconvenient operation.
In order to solve the above problems, the utility model proposes a kind of artery remaining blood gas analysis needle, including trochar, puncture
Pin and collection blood needle tubing；Described sleeve pipe pin includes the sleeve pipe and casing seat being fixedly connected, and is formed with and sleeve pipe in described sleeve pipe seat
The flow liquid road communicated；The puncture needle includes nook closing member and punctures seat, and one end of the nook closing member is connected with puncturing seat, other end edge stream
Fluid passage is piercing in sleeve pipe；The collection blood needle tubing includes syringe and core bar that grafting is slidably matched, and syringe is with nook closing member by puncturing seat
It is connected；Provided with the branch pipe communicated with flow liquid road on described sleeve pipe seat；Set in the branch pipe with flow liquid road connectivity part
There is the three-way valve core of T-shape path, select sleeve pipe to be turned on syringe or branch pipe by the rotation of three-way valve core；The nook closing member is worn
The T-shape path of three-way valve core is crossed, torsion spring, the two ends of the torsion spring are provided between the bottom of the three-way valve core and casing seat
It is connected respectively with casing seat and three-way valve core.
Further, rotary position limiting structure, the rotary position limiting structure are provided between the three-way valve core and casing seat
It is included in the limited block formed on casing seat and the block formed on three-way valve core, when extracting nook closing member out of trochar, turns round
Spring drives three-way valve core to rotate, and limited block coordinates limitation three-way valve core rotational angle with block so that three-way valve core turns on sleeve pipe
With branch pipe.
Further, in addition to the conduit that is connected with the branch pipe of one end, the other end of conduit is used to connect with monitoring device.
Further, in addition to the wrist strap with two connection ends, wrist strap be connected with described sleeve pipe seat passes through two and connected
End is fixed in wrist.
Further, in addition to detection needle tubing, the detection needle tubing is connected on the conduit, is passed through the detection needle tubing and is examined
That surveys sleeve pipe puts pipe situation.
Further, the scale provided with observation sleeve pipe paracentesis depth in described sleeve pipe.
The beneficial effects of the utility model are：
1st, the setting of torsion spring, can be when extracting puncture needle, and three-way valve core automatic rotary transfers conductive channel, so reduces
The problem of manual operation rotates three-way valve core, while simple in construction, convenient operation.
2nd, position limiting structure can improve the rotational positioning precision of three-way valve core.
3rd, during puncture needle is extracted, gush out not smooth or stop gushing out when running into arterial blood, it is meant that need
When adjusting locating sleeve position.Puncture needle can be fallen back on after three-way valve core, side pipe path is opened naturally, by detect needle tubing to
Puncture needle insertion is passed outside sleeve pipe, adjusts the position of sleeve pipe by a little anti-freezing liquid medicine of injection in sleeve pipe, swivel tee valve element；
And when radial artery detaining tube is good, equally after puncture needle falls back on three-way valve core, can accomplish quickly to inject a certain amount of anti-freezing
Liquid medicine, avoids the arterial blood in sleeve pipe and casing seat from resting on for a long time outside blood vessel in time.
4th, the depth that sleeve pipe is punctured, can help junior doctor to judge to puncture the position turned to during blood back is punctured, from
And improve the success rate punctured.
5th, medical worker is after Radial Artery Cannulation success, it usually needs be fixed with a plurality of medical proof fabric, and this
Wrist strap in utility model, can be after pipe success be put, more effectively fixed sleeving.The doctor using excessive or large area is avoided simultaneously
The inconvenience brought with adhesive plaster.And elimination long-time larger area pastes medical adhesive tape, and skin tape at patients wrist is come
Harmful effect.
