Background technology
Cricothyroid membrane puncture needle is applicable to acute laryngeal obstruction, and especially vocal area blocks, and severe dyspnea has little time to set up artificial airway's patient, can implement thyrocricocentesis rapidly, to alleviate dyspnea.Because the people will stop suffocating in 2～4 minutes in heart beating, irreversible pathological changes appears in brain, if and medical personnel can not arrive and handle in the so short time, the chance that patient can survive is just very little, so the rescue of this moment must be seized every minute and second, preferably the right and wrong medical personnel also can operate, and this just requires the cricothyroid membrane puncture needle must be easy to carry, easy to use and effect is remarkable, so dyspnea that just can reduction of patient before medical personnel are on the scene.
Summary of the invention
The purpose of this invention is to provide the also operable portable cricothyroid membrane puncture needle of a kind of medical personnel easy to carry, easy to use, non-, implemented by the Field Force in the very first time of the capable thyrocricocentesis of needs, life to greatest extent gives emergency treatment to a patient.Win the quality time for the rescue in medical personnel's later stage, reduce the sick and wounded's mortality rate to a great extent.
For achieving the above object, the present invention includes handle, puncture needle and portable the button, puncture needle is a trocar design, comprise puncture needle tubing and puncture nook closing member two parts composition, the puncture needle tubing is a hollow-core construction, the puncture nook closing member is a solid, be positioned at the cavity of puncture needle tubing, the tip that the needle tip of puncture nook closing member passes the puncture needle tubing closely is connected with the most advanced and sophisticated of puncture needle tubing, seam is level and smooth and form a solid syringe needle, puncture needle tubing and puncture nook closing member have a base respectively, there is spiral interface the anterior outside of the base of puncture needle tubing base inner and the puncture nook closing member, the puncture needle tubing is connected with puncture nook closing member spiral, the tip of described puncture needle tubing is slick and sly concordant otch, the tip of puncture nook closing member is sharp rhizoma sparganic or four ribs or circular cone syringe needle, described handle is a hollow tubular, can put into puncture needle, the one end inside of handle is respirator or artificial ventilator standard interface, other end outside is a spiral interface, there is spiral interface the inside, base rear portion of described puncture nook closing member, the base rear portion of puncture nook closing member can be connected with the spiral interface of handle, the base of described puncture needle tubing can be connected with the spiral interface spiral of handle, and described portable button can be connected with the spiral interface of handle.The standard interface of described handle is put at puncture needle under the state of handle with the helical structure spiral of the outside, middle part of puncture nook closing member base and is connected.The external diameter of described puncture needle tubing is 4.5mm, and internal diameter is 3.5mm.The length (L) of described puncture needle tubing protuberate basic unit is 40-50mm.Described puncture needle tubing and puncture nook closing member are that the flexible alloy material of high strength is made.
Under the resting state, portable button is connected with the spiral interface of handle, and puncture needle is put into handle, and handle standard interface end is connected with puncture nook closing member base middle part, makes handle become the needle guard of puncture needle, and whole structural texture is small and exquisite, is convenient for carrying.
Under the puncture state, the spiral interface of handle is connected with the spiral interface at puncture nook closing member base rear portion.
Under the user mode of puncture back, the spiral interface of handle is connected with the spiral interface of puncture needle tubing base.
In sum, advantage of the present invention is: volume is small and exquisite, easy to carry, effect is remarkable, owing to used the principle and the technology of the trocar, more reliable than using the common syringe syringe needle to carry out the thyrocricoid puncture operation, the puncture needle tubing can not stop up in the piercing process, it is better that the puncture needle tubing is more known a little about airway dysfunction, puncture needle tip end is level and smooth otch, the puncture back is difficult for patient is damaged, easy to carry under the resting state, under the user mode operation simple and easy, non-medical personnel also can operate, medical personnel more can carry, and have improved the dysfunction of ventilation patient's who causes because of airway obstruction salvage success rate greatly.
