Description
Technical field
This utility model belongs to medical apparatus, is related to a kind of emergency airway handling implement, and in particular to a kind of ring first film is worn
Thorn device.
Background technology
Thyrocricoid puncture be clinically for have respiratory tract obstruction, severe dyspnea patient adopt first-aid method it
One, it can gain time for tracheotomy, be the important component part of field first aid.It has easy, quick, effective simultaneously
Advantage, current cricothyroid membrane puncture needle mostly be sleeve pipe pin type：I.e. built-in sharp property puncture needle, overcoat plastic ventilation conduit, during use,
Puncture needle and trocar sheath need to be firmly pushed, which is disadvantageous in that overcoat often occurs in Jing as overcoat pipe diameter is bigger than puncture needle
Pipe inserts difficulty, and sometimes also as the control of puncture needle insertion depth is bad, insertion is too deep to be caused to puncture offside tracheal wall, damages ring
First film, or even cause the situation of the severe complications such as tracheo esophageal fistula.
The content of the invention
The purpose of this utility model is that a kind of thyrocricoid puncture of offer is more smooth, and can prevent from wearing ring first film by mistake
Sting device.
For achieving the above object, this utility model provides following technical scheme：It is disposably anti-error to wear thyrocricoid puncture device,
Including puncture needle, it is characterised in that：The puncture needle is hollow tubular, and the rear end of puncture needle is provided with endotracheal tube interface, punctures
The resilient protection head that can slide up and down is provided with inside pin, damping spring, puncture needle front end side behind resilient protection head, is provided with
Outer vent is provided with, the side of resilient protection head also is provided with corresponding interior passage, after resilient protection head ejects head, described
Interior passage is alignd with the outer vent and is communicated, and is effectively improved ventilation, and can be prevented puncture needle from damaging offside trachea.
Further, the puncture needle is provided with limit fixator, can prevent puncture needle slide.
Further, the puncture needle is provided with protection head position instruction window, is easy to observe resilient protection head ejection situation.
Further, the interior passage and outer vent respectively have 1-4, further to improve ventilation.
Further, the dry leading portion of the pin of the puncture needle and resilient protection head are straight or arc.
When in use, after puncture needle penetrates skin, due to the resistance of skin and flesh, resilient protection head can be reduced to and wear this utility model
Inside pricker, puncture is not so interfered with, puncture needle more easily enters trachea, after piercing needle enters trachea antetheca, gas
It is hollow, no resistance in pipe, now resilient protection head can be ejected, and after ejection, its head stretches out the outside of puncture needle, and length surpasses
The tip position of puncture needle is crossed, so as to ensure that needle point will not damage trachea rear wall, without the need for inserting trocar sheath again after puncturing success, can
Respirator or respiratory balloon row assisted ventilation are connect directly.
The utility model has the advantages that：Puncture needle is melted into a whole with airway, it is more smooth during thyrocricoid puncture, subtract
Injury and pain in light piercing process, can prevent the needle stick injury trachea rear wall of puncture needle, damage ring first film, it is to avoid cause gas
The situation of the severe complications such as pipe esophageal fistula, this utility model can fast and effectively set up breathing circuit, reduce sending out for complication
It is raw, and flow process is simple, save time, safety, it is adaptable to the first aid to having respiratory tract obstruction, the patient of severe dyspnea.

Specific embodiment
Refer to Fig. 1, it is of the present utility model it is disposable it is anti-error wear thyrocricoid puncture device, including puncture needle 2, its feature exists
In：The puncture needle 2 is hollow tubular, and the rear end of puncture needle 2 is provided with the endotracheal tube interface 1 of standard, is provided with inside puncture needle 2
Can slide up and down resilient protection head 8, and damping spring 3 is provided with behind resilient protection head 8, and 2 front end side of puncture needle is provided with outer
Passage 7, the side of resilient protection head 8 also are provided with corresponding interior passage 6, after the resilient protection head 8 ejects head, institute
State interior passage 6 and align with the outer vent 7 and communicate.The puncture needle 2 is provided with limit fixator 5, on the puncture needle 2
Protection head position instruction window 4 is provided with, the interior passage 6 and outer vent 7 respectively have 1-4, can increase ventilation more than quantity.Institute
The dry leading portion of pin and resilient protection head 8 for stating puncture needle 2 is straight or arc, and will the ensureing of circular arc can not affect resilient protection head
(8) normal activity.
During use, the right hand holds puncture needle 2, and needle tip alignment point of puncture, firmly rotation are pierced into skin 9, resilient protection
8 bounce back in puncture needle tubing, and when puncture needle breaks through trachea antetheca 10, resilient protection head 8 is ejected to puncturing outside needle tubing, is passed through
Observation place indicating window 4 confirms the position of resilient protection head 8, so as to effectively prevent puncture needle from damaging trachea rear wall 11, same to time limit
It is too deep that position holder 5 can prevent puncture needle from entering.Without the need for inserting trocar sheath again after puncturing success, respirator or breathing can be directly connect
Sacculus row assisted ventilation, aforesaid operations effectively set up the generation that breathing circuit reduces complication, and flow process is simple, save time,
Safety, is worth of widely use.
