Abstract
The utility model relates to an oxygen inhalation mask for measuring end-expiratory carbon dioxide, in particular to an oxygen inhalation mask for measuring end-expiratory carbon dioxide which can be connected with an end-expiratory carbon dioxide monitoring instrument for monitoring the breathing situation while the oxygen is inhaled, which is characterized in that: a small pipe is arranged on the top part of an ordinary oxygen-inhalation mask shell, an outer end port of the small pipe is connected with a bypass-type end-expiratory carbon-dioxide measured sampling pipe, the inner end of the small pipe is connected with a section of a threaded small pipe which is free to stretch and retract, the monitoring instrument can collect gas inside the mask through the retracted threaded small pipe so as to measure the variation of the expiratory carbon dioxide of a patient, and the variation of the carbon dioxide is reflected as a carbon dioxide oscillogram with a given frequency and given amplitude on the monitoring instrument, so that a purpose on monitoring the breathing of the patient can be realized; and the threaded small pipe also can be stretched, and the front end of the threaded small pipe can be arranged inside one side nasal cavity of the patient to monitor the end-expiratory carbon dioxide level of the patient.
Description
Technical field
This utility model relates to a kind of medical oxygen absorption mask, but the monitor monitoring patient respiratory situation of connecting band end-expiratory carbon dioxide monitoring and the device of carbon dioxide level when exhaling mask oxygen-inspiration time the when relating in particular to recovery behind non-intubation and general anaesthesia and the intubation and general anaesthesia tube drawing.
Background technology
The structure that is widely used in clinical common oxygen absorption mask at present comprises: there are some diffusing gas apertures, shaping sheet metal in triangle body mask shell, housing both sides, climb band, air inlet pipe interface, oxygen catheter.When the patient needs mask oxygen-inspiration, oxygen catheter is connected to the delivery outlet end of oxygen flow meter, the mouth and nose that face shield fixedly covered the patient can be accomplished oxygen uptake.But common face shield has only the oxygen uptake function.And behind non-intubate general anesthesia and intubate general anesthesia tube drawing during recovery most of patients in various degree respiration inhibition and respiratory tract obstruction are all arranged; The monitoring project that can reflect the breathing situation in the art has only detecting sphygmus and blood oxygen saturation; There are many shortcomings again in detecting sphygmus and blood oxygen saturation reflection breathing situation: one is subject to external interference and can survey; As when shivering with cold; Two hysteresis qualitys just show as decline like patient's detecting sphygmus and blood oxygen saturation after asphyxia can reach 3-5 minute after the abundant oxygen uptake in advance, and actual patient has at this moment existed tangible anoxia and serious carbon dioxide accumulation.This also is to meet accident during recovery behind present non-intubate general anesthesia and the intubate general anesthesia tube drawing and cause one of main causes of death.U.S. anesthesia doctors'associations (ASA) just clearly stipulate: monitor end-expiratory carbon dioxide unexpectedly for the breathing in the minimizing anesthesia process and be the routine monitoring project in the anesthesia.But the monitor with end-expiratory carbon dioxide monitoring can only be used for its end-expiratory carbon dioxide level of tracheal intubation patient-monitoring at present.And common face shield can't be connected with the monitor of band end-expiratory carbon dioxide monitoring, also just can't monitor patient's breathing situation and end-expiratory carbon dioxide level at mask oxygen-inspiration simultaneously.
Summary of the invention
Can promptly and accurately understand patient respiratory situation and end-expiratory carbon dioxide level for making in oxygen uptake, this utility model provides a kind of and surveys the oxygen absorption mask that can survey end-expiratory carbon dioxide that the end-expiratory carbon dioxide sampling tube is complementary with the by-pass flow formula.This oxygen absorption mask can not only oxygen uptake and the breathing situation and the end-expiratory carbon dioxide level that can be connected and monitor the patient with the monitor of band end-expiratory carbon dioxide monitoring simultaneously.
This utility model solves the technical scheme that its technical problem adopted: establish a tubule on common oxygen absorption mask housing top and be fixed in mask shell; There are air dispelling hole, moulding sheet metal in the mask shell both sides and climb band; The upper end is provided with oxygen intake pipe and is connected with oxygen catheter, and a tubule is established at the mask shell top, and tubule is a rigid plastics; Its mask shell outer end interface is a standard interface; Can survey the end-expiratory carbon dioxide sampling tube with the by-pass flow formula and be connected, the inner interface of tubule is fixedly connected one section telescopic screw thread tubule, and the screw thread tubule is a flexible pipe.In the time of in the time of patient's oxygen uptake, need monitoring breathing situation and end-expiratory carbon dioxide level; Give patient's mask oxygen-inspiration earlier; Again the by-pass flow formula being surveyed the end-expiratory carbon dioxide sampling tube is connected with the vertical outer section tubule of mask shell; Monitor can be gathered patient's in the face shield expired gas through the screw thread tubule, on monitor, demonstrates the carbon dioxide waveform figure of certain frequency and amplitude, and this oscillogram can reflect patient's respiratory frequency and amplitude and the carbon dioxide level of measuring its expired gas.Also can the screw thread tubule be stretched to the side nasal cavity that certain-length is inserted the patient, not influenced by the flushing of fresh Oxygen Flow, can reflect the breathing situation better and can monitor the end-expiratory carbon dioxide level more accurately.And can reflect partial pressure of carbon dioxide in the dynamic blood indirectly, avoid the loaded down with trivial details of survey vim and vigour of drawing blood repeatedly.This is simple to operation, and monitoring is observed easily: have the carbon dioxide waveform that breathing is promptly arranged, no carbon dioxide waveform is an apnea.
The beneficial effect of this utility model is: is connected with the monitor of band end-expiratory carbon dioxide monitoring when can be used for breathing patient's row mask oxygen-inspiration of recovering behind unsettled non-intubate general anesthesia and the intubate general anesthesia tube drawing, thus objective patient respiratory situation and the end-expiratory carbon dioxide level of monitoring effectively.
