Abstract
This utility model provides a kind of artery remaining blood gas analysis needle, comprising: the trocar and inspection section; The trocar comprises syringe needle and needle tubing; Syringe needle, comprises nook closing member, trocar sheath, isolated tube, needle handle.It is 0ml-1.0ml that inspection section outer surface indicates scope, and inspection section internal diameter is 3mm, and inspection section inner surface scribbles anticoagulant.Its advantage is, when blood back enters after in inspection section, the form that can spring up in cylinder according to blood, judges the opportunity of inserting trocar sheath, so just greatly can increase the success rate that disposable puncture puts pipe, reduce secondary puncture and put the pain of injury and economic loss that pipe brings to patient.Meanwhile, the blood in inspection section fast timely for arterial blood gas analysis, can save time, and avoids waste.
Description
Technical field
This utility model belongs to the technical field of clinical middle anesthesiology, particularly one improvement puncture and intubation device.
Background technology
At present, this technology of puncture and intubation mainly relies on feel and the clinical experience of operator, for just entering the student of bedside practice, is very large challenge.What operator saw blood in puncture cannot judge trocar sheath at once whether in blood vessel, be now insert trocar sheath immediately or force down that pin is dry continue inserting needle 1-2mm after again row insert trocar sheath, judge to get up especially difficulty.Owing to being by touching blind wearing, the angle of puncture inserting needle is easy to into angle with radial artery, and 1-2mm just likely wears out the sidewall of tremulous pulse, and now Aculeata has been filled with blood, and operator cannot judge the position of needle point exactly, is easy to cause putting tube failure.
If put tube failure first, radial artery because stimulate spasm or local hematoma to make follow-up puncture and intubation become more difficult, also can bring the very large pain of injury to patient simultaneously.
A kind of wire needle is also had to be used for Arterial puncture intubation art in clinical practice, carry out trocar sheath by means of seal wire and put pipe, success rate is also higher, and the success rate of improvement puncture and intubation device does not have notable difference, but the more general arterial puncture needle of this pin external diameter is thick, puncture pain is stronger, blood back speed is comparatively slow, and price is approximately 10 times of common pin, very expensive, therefore, in developing country, especially China is difficult to universal.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of arterial blood gas indwelling dissecting needle, overcomes the low defect of puncture and intubation success rate by increasing an inspection section.
This utility model provides a kind of artery remaining blood gas analysis needle, it is characterized in that, comprising: the trocar and inspection section; The trocar comprises syringe needle and needle tubing; Syringe needle, comprises nook closing member, trocar sheath, isolated tube, needle handle; Trocar sheath is enclosed within outside nook closing member, and trocar sheath lower end and isolated tube are fixed; Nook closing member is fixed on the center of isolated tube; Nook closing member lower end extend in needle tubing; Needle tubing, is positioned at syringe needle lower end; Inspection section, is positioned at trocar lower end.
Further, this utility model provides a kind of artery remaining blood gas analysis needle, can also have such feature:
Needle handle comprises protrusion and both wings, and both wings are arranged on the both sides of isolated tube, and protrusion is arranged on isolated tube one end relative to both wings.
Further, this utility model provides a kind of artery remaining blood gas analysis needle, can also have such feature:
Both wings are butterfly.
Further, this utility model provides a kind of artery remaining blood gas analysis needle, can also have such feature:
There is recess isolated tube lower end, and recess is arranged on the same side of both wings; Needle tubing upper end arranges a tang, and tang matches with recess and is connected.
Further, this utility model provides a kind of artery remaining blood gas analysis needle, can also have such feature:
Inspection section inner surface scribbles anticoagulant.
Further, this utility model provides a kind of artery remaining blood gas analysis needle, can also have such feature:
Inspection section outer surface indicates scale.
Further, this utility model provides a kind of artery remaining blood gas analysis needle, can also have such feature:
The range ability of inspection section is 0.5ml-1.0ml.
Further, this utility model provides a kind of artery remaining blood gas analysis needle, can also have such feature:
The internal diameter of syringe cylinder is 2-4mm.
The beneficial effect of utility model:
The object of a kind of artery remaining blood gas analysis needle that this utility model provides is: Blood return time is extended greatly, operator can adjust needle angle and the degree of depth according to Blood return time at leisure, greatly improve puncture and intubation success rate, strengthen the confidence of operator, alleviate misery and unnecessary economic loss that two-time catheterization brings to patient, meanwhile, the blood in inspection section can fast timely for arterial blood gas analysis, save time, avoid waste.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further described.
As shown in the figure, artery remaining blood gas analysis needle comprises: the trocar 100 and inspection section 200, both removably connect.
The trocar 100 comprises syringe needle 10 and needle tubing 20.Syringe needle 10 comprises nook closing member 11, trocar sheath 12, isolated tube 13 and needle handle composition.Needle tubing 20 is positioned at syringe needle 10 lower end, and inspection section 200 is positioned at the trocar 100 lower end.
Trocar sheath 12 is enclosed within outside nook closing member 11, and trocar sheath 12 lower end and isolated tube 13 are fixed, and nook closing member 11 is fixed on the center of isolated tube 13.Nook closing member 11 lower end extend in needle tubing 20.Needle handle comprises protrusion 14 and both wings 15.Both wings 15 are arranged on the both sides of isolated tube 13, and both wings 15 are in butterfly.Protrusion 14 is arranged on the other end of isolated tube 13 relative to both wings.When inserting needle, forefinger props up both wings 15, and thumb is pinned protrusion 14 and carried out inserting needle.
There is recess 16 isolated tube 13 lower end, and recess is arranged on the same side with both wings 15.
Needle tubing 20 upper end is provided with a tang 21, and to be matched with recess 16 by tang 21 and be connected, can well locate, plug is convenient.
Inspection section 200 outer surface indicates scale, and the range ability of scale is 1.0ml, and the inner surface of inspection section 200 scribbles anticoagulant, as heparin etc., can solidify in inspection section 200 by effectively anti-Hemostatic Oral Liquid.The internal diameter of inspection section 200 is 3mm, certainly, also can be 2mm, 4mm or other sizes.Can know like this and see that blood springs up in inspection section, make to put pipe success rate and improve.If inspection section is meticulous, cause inspection section long, be inconvenient to operate.If inspection section is excessively thick, cause blood flow rate slow, clearly cannot judge that whether arterial blood is in flowing.
The work process of artery remaining blood gas analysis needle is as follows:
Operator holds needle handle, and make artery remaining blood gas analysis needle become 10-20 to spend angle inserting needle with skin, after seeing blood back in needle tubing, then inserting needle is about 2mm, when see in inspection section blood be wave spring up backward time, insert trocar sheath.Operator, while operation, sees in inspection section, if slow blood flow or without blood pollex, can the withdraw of the needle to subcutaneous, adjusting left and right directions slightly, then row puncture, is gush row again after pulsation type to insert trocar sheath until blood.If blood flow rate is stablized in inspection section, illustrate that trocar sheath inserts Ink vessel transfusing.
After completing Arterial puncture intubation, take off observing tube.Blood in observing tube may be used for blood gas analysis.
