Description
Technical field
The present invention relates to a kind of medical first aid utensil, particularly a kind of thyrocricoid puncture T shape ventilation trocar.
Background technology
As everyone knows, human body can not tolerate anoxia, continues several minutes severe depletion of oxygen, can cause the infringement of body generation irreversibility.In the first aid process at the scene,, must promptly set up the artificial airway when patient self can not guarantee effective autonomous respiration and face shield pressure-vent can not improve anaerobic condition the time.Artificial airway's foundation at present mainly contains tracheal intubation, tracheotomy, technology such as film incision of ring first and thyrocricoid puncture.Because tracheal intubation; Tracheotomy is relatively complicated with the operating procedure that ring first film cuts these three technology; In case of emergency; Even received the personnel of professional training also can't guarantee in short-term to accomplish smoothly, therefore a lot of patients wait for or implement tracheal intubation, tracheotomy or encircle irreversible anoxia infringement has just taken place in the process that the first film cuts in addition life unexpected.And the thyrocricoid puncture technical operation is simple relatively, and the people who accepts first aid education a little can grasp, so the rescue that successful implementation thyrocricoid puncture ventilation can be patient tries to gain time precious to one.
Existing thyrocricoid puncture technology is directly to puncture ring first film with one piece of thick needle, to reach the purpose of improving patient ventilating.The interface of device (breathing bag or respirator) owing to breathe no more; Can't carry out respiratory control to patient; Therefore guarantee that the effective prerequisite of this way is that patient will have autonomous respiration or need be by the high frequency jet ventilation machine, this also is one of limitation of conventional thyrocricoid puncture technical application in the past.
To the use limitation of routine techniques, a lot of follow-on thyrocricoid puncture ventilation external members are devised.These external members mainly can be divided into two types, and one type is simple ventilation type external member, as adding a respiratory organ interface at bodkin collar extension place, controls ventilation.The ventilating mode that this type external member can be carried out is more single, is prone to cause when the patient that autonomous respiration is arranged is carried out assisted ventilation breathe antagonism, thereby can not effectively improves anaerobic condition.And owing to lack the oxygen catheter interface, the patient who keeps autonomous respiration can not effectively be cured by oxygen therapy, thereby patient's anaerobic condition is improved limited.In addition, this type external member lacks air vent, is combined patient that upper respiratory tract blocks when controlling ventilation, because gas can not effectively be got rid of in patient's lung, is prone to cause air flue to weigh wounded.Another kind of is the function composite external member; Such external member also is compounded with devices such as dermatotome, sputum aspirator tube except the respiratory organ interface is arranged; The design of this type external member is complicated; The field first aid personnel are not easy correctly to grasp its method for using, thereby have often incured loss through delay valuable emergency time, cause patient the generation of anoxia infringement to occur.Therefore; Design a kind of ventilation that can adopt different mode according to patient's state of an illness, simple to operate again, thus really can improve patient's anoxia in the on-the-spot performance of first aid; The give emergency treatment to a patient cricothyroid membrane puncturing and ventilating device of life all is vital for first-aid personnel and patient.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art and a kind of perfect in shape and function is provided; Can adapt to different state of an illness needs; Operational approach is simple again simultaneously, and the first-aid personnel is easy to grasp, and can fast and effeciently accomplish the thyrocricoid puncture T shape ventilation trocar of thyrocricoid puncture ventilation.
A kind of thyrocricoid puncture T shape ventilation trocar; Comprise T shape breather and ventilation tube core; One end of said T shape breather is provided with standard respiratory organ joint; The other end is sealedly connected with the puncture trocar sheath; The caliber of said T shape breather is less than the caliber of said standard respiratory organ joint; Also be provided with the standard oxygen catheter joint that is communicated with said T shape breather internal cavities on the body of said T shape breather, said T shape breather and said puncture trocar sheath junction are provided with the fixed-wing that can be fixed on the human body, and the end of said ventilation tube core is provided with the puncture needle of diameter less than said puncture trocar sheath internal diameter; Said ventilation tube core is provided with than the big rubber seal of said T type breather internal diameter with said puncture needle junction, and said ventilation tube core is inserted in the said T shape breather and through said rubber seal and said T shape breather inner wall sealing.
Among the present invention, said puncture trocar sheath is provided with protective sleeve outward.
Among the present invention, the length of said puncture needle is greater than the length of said puncture trocar sheath, and the length of said ventilation tube core is greater than the length of said T shape breather, and the end of said ventilation tube core is provided with handle.
Among the present invention, the end sides of said puncture trocar sheath is provided with a plurality of pores.
Among the present invention, said fixed-wing is the butterfly fixed-wing.
The present invention has introduced the notion of T pipe ventilation first in thyrocricoid puncture; As a kind of breather, T pipe both can connect breathing bag or breathing machine ventilation, also can ventilate having only under the situation of external oxygen source; Both can keep patient's autonomous respiration, also can control or assisted ventilation.Therefore, this device can effectively improve the limitation of present thyrocricoid puncture ventilation external member, and the ventilation of different mode is provided for the patient of different situations.In addition, the present invention adopts lancet puncture, and the design of puncture trocar sheath ventilation can effectively reduce the incidence rate that conventional cricothyroid membrane puncture needle punctures complication such as esophagus; Puncture trocar sheath tip is other to be provided with side opening, can increase ventilation, reduces the risk that sleeve pipe stops up; T shape breather front end is provided with the butterfly fixed-wing, can play fixedly breather, prevents the effect of slippage; And the ventilation tube core links to each other with puncture needle to hold the airtight circle of rubber is arranged; Make ventilation tube core and T shape breather lump together the effect of just having played a syringe, when puncture, as long as pumpback ventilation tube core; If have gas to be drawn in the T shape breather; Explain that the trocar has got into trachea, this T shape ventilation trocar can be used under the situation of external syringe need not, further simplified operating process.Because the T shape breather among the present invention, the operational approach of critical pieces such as paracentesis trocar is all comparatively simple, therefore in case of emergency can improve its correct utilization rate greatly.In addition; Unique T shape breather design, making itself just becomes a kind of easy respiratory organ, even under the situation of apnea capsule or respirator, also can ventilate; Therefore reduced dependency degree, adaptable across adult and child's first aid thyrocricoid puncture ventilation to outside breathing equipment.In sum, this device construction is light and handy, can be positioned in each first aid place or the emergency case subsequent usely, really plays gizmo, the purpose of big effect.
