Description
Technical field
This utility model patent relates to a kind of medical apparatus and instruments articles for use, particularly one can be on-the-spot quickly in first aid
The portable head low temperature induction device of application.
Background technology
Therapeutic Mild Hypothermal, it is verified that the ischemia-anoxia-induced apoptosis of core target organ can be alleviated, improves patient
Function of nervous system and survival region.A variety of causes (global brain ischemia that cardiac arrest causes, in wind-induced office
Portion's ischemia and serious craniocerebral trauma etc.) brain tissue impairment that causes needs to treat as soon as possible, during except first
Between use various method ensure cerebral tissue blood perfusion outside, implement the local therapeutic low temperature energy of head as early as possible
Enough cerebral tissue edema that significantly alleviates, the damage of minimizing brain tissue cell, improves prognosis.Mild hypothermia therapy in the past
The induction mode using total body hypothermia or the cooling of skull outer surface more, required induction time is long, in cerebral tissue
Portion's cooling is undesirable, it is difficult to quickly the nervous system to head is formed and protects fast and effectively, is badly in need of novel
Non-invasive manner from the beginning intracranial part implement effective low temperature induction.
Utility model content
The purpose of this utility model is to provide a kind of portable head low temperature induction device, it is possible to quick, noinvasive
Ground from the beginning intracranial part produces low temperature, the environment such as in applying also for the emergency transportation vehicles, in institute, it is simple to urgency
The personnel that rescue quickly apply in clinical emergency treatment, effectively solve problems of the prior art.
The technical scheme that this utility model is taked is:
A kind of portable head low temperature induction device, it is characterised in that include pipe-line system, described pipe-line system
Include the high velocity air portion of the initial segment, the parallel portion of gas refrigerant of interlude and the mixing of nasopharynx section successively
Ejection section, wherein: described high velocity air portion includes the gas tube of a hollow, is used for importing high-speed gas；
The parallel portion of described gas refrigerant includes the gas tube extended to by high velocity air portion and for importing cold-producing medium
Refrigerant pipe, described gas tube does not connects in the parallel portion of gas refrigerant with refrigerant pipe, independent the most also
OK；Described mixing jetting portion include spray-hole, Hybrid connections pipe and by the parallel portion of gas refrigerant extend and
The gas tube come and refrigerant pipe, described spray-hole makes gas tube and outside communicate, described Hybrid connections Guan Lian
Connect refrigerant pipe and spray-hole, pass through said structure so that gas tube and refrigerant pipe are in mixing jetting portion
Being interconnected at spray-hole, the high-speed gas injection that cold-producing medium is introduced from gas tube by spray-hole is to nasopharynx
Intracavity.
Further, described portable head low temperature induction device, also include refrigerant flow controlling device.
Further, described refrigerant flow controlling device include refrigerant storage high-tension rubber cuff,
Store cuff support and control valve.During use, refrigerant storage is in high-tension rubber cuff, by cuff
Autogenous shrinkage power (retraction elastic force) extrudes, and drives cold-producing medium to enter in refrigerant pipe from storing cuff, and
Enter cavum nasopharyngeum eventually.It is the storage cuff support of metal or plastics outside refrigerant storage high-tension rubber cuff,
Ensureing to store the shape of cuff, control system by selecting the connection conduit of certain internal diameter or can be arranged at connection
Supravasal simple control valve gate control refrigerant flow rates.
Or, described spray-hole, towards the different direction opening of two or more, makes the multi-faceted enforcement of injection.
During use, by the high velocity air portion of pipe-line system the initial segment by high velocity air (generally 70-80 liter/
Minute) bring into, the parallel portion of gas refrigerant at pipe-line system interlude is by cold-producing medium molten, that boiling point is relatively low
(the most own halothane) or brine ice are brought into, and make gas and system in the mixing jetting portion of pipe-line system nasopharynx section
Cryogen is sufficiently mixed and injection release in cavum nasopharyngeum, and cold-producing medium volatilizees rapidly under the effect of high velocity air,
It is changed into steam state by liquid, and absorbs ambient heat in a large number, in cavum nasopharyngeum (basis cranii), produce low temperature.
Produce after using above-mentioned technical scheme and have the beneficial effect that use device described in the utility model can letter
Just, quickly, low temperature induction effect is effectively produced.
