Description

The inhalation anesthesia dedicated facemask
Technical field
The present invention relates to a kind of medical anaesthetic mask, specifically relate to a kind of face shield of inhalation anesthesia special use.
Background technology
Sucking general anesthesia is one of clinical the most frequently used general anesthesia method.Be used at present clinical inhalation anesthesia method and comprise that mainly endotracheal intubation sucks, laryngeal mask sucks and face shield sucks.Endotracheal intubation sucks and the laryngeal mask inhalation anesthesia all has the invasive operation, also usually easily causes relevant complication; It is simple that the face shield inhalation anesthesia has operational approach, and the advantage of Noninvasive is particularly suitable for inducing and keeping of pediatric anesthesia; But shortcoming also clearly, the one, because it belongs to open inhalation anesthesia, can produce a large amount of waste gas of anesthesia contaminated operation chambers, the medical worker works under this air-polluting environment for a long time not only affects health, also easily produce spiritual tried out, can not concentrate on work, there is very large potential safety hazard in the patient.The 2nd, the face shield inhalation anesthesia can't be monitored the patient respiratory situation and monitor inhalational anesthetic concentration by carbon dioxide waveform figure on the monitor, and particularly the inhalation anesthesia degree of depth can't be understood and control to the anesthetic concentration of patient's exhalation also just.So present open inhalation anesthesia method is to the stage that substantially is eliminated.
Summary of the invention
In order to solve the technical problem of open face shield inhalation anesthesia exhaust emission operating room environment and monitoring inhalation anesthesia concentration, the invention provides a kind of face shield of inhalation anesthesia special use of simple to operate, practicality easy to use, safe, this face shield not only can not cause operating room to pollute when using, and the monitor inhalation anesthesia concentration that can be complementary with the monitor with the anesthetic gases monitoring.
The present invention solves the problems of the technologies described above the technical scheme that adopts to be: a kind of inhalation anesthesia dedicated facemask of the present invention, it comprises mask body, inflation curtain, gas extraction system and four aspects of monitoring system.Mask body by mask shell, air bag cushion, air bag ring, air inlet pipe and climb the band form; Bottom one circle of described mask shell is provided with a circle air bag cushion, and air bag ring is attached on the air bag cushion, and air bag cushion is provided with an air-filled pore, for air bag ring inflation venting.Air inlet pipe on the described mask body is positioned at the top of mask shell, and its length is 10-20cm approximately.Face shield covers patient's mouth and nose, and is fixing to climb band, and air inlet pipe is connected with anaesthetic apparatus screwed pipe and can makes the patient be in narcotism for patient's oxygen uptake and inhalation anesthetic.
Described inflation curtain comprises curtain top, inflation curtain cover; The curtain top is fixed in air inlet pipe topmost and is moved into trachea outer wall one circle and forms umbrella shape, and the plane that bottom one circle on curtain top forms and curtain push up domatic formation 30 degree angles, and described curtain top is rigid plastics.An air-filled pore is established in curtain top/bottom part and junction, curtain cover top, inflates for the curtain cover.After the inflation of curtain cover curtain cover wall is expanded and form up-small and down-big drum-shaped, make whole curtain form approximately 10 liters capacity, can collect patient's Exhaled gasesS and waste gas of anesthesia.The curtain wall is by inside and outside two-layer the composition, and two-layer centre is airtight lacuna, and material is soft plastic material.
Described gas extraction system comprises exhaustor, attracts leather hose and vacuum extractor; Exhaustor is located at curtain and leans nearly air inlet pipe place, and exhaustor one end is in curtain, and the other end links to each other with attracting leather hose one end, attracts the leather hose other end to be connected with vacuum extractor.Vacuum extractor is opened traffic attraction is remained on about 20 Liter Per Minutes, and the oxygen flow of general anesthetic machine is approximately opened the Liter Per Minute to 3-5, traffic attraction can all siphon away the patient's expired gas in the curtain and waste gas of anesthesia and make much larger than oxygen flow and continue to be in certain negative pressure state in the curtain like this, and extraneous air can enter constantly by the curtain bottom that unlikely cause in the curtain crosses by force negative pressure also the unlikely waste gas of anesthesia that causes leaks outside in the curtain.
Described monitoring system comprises sampling tube, tubule, screw thread tubule and Y tube and with the monitor of end-expiratory carbon dioxide monitoring; Described tubule is located at the middle part, front of mask shell and is run through mask shell, tubule medial extremity connecting thread tubule, the tubule outboard end is connected with sampling tube, sampling tube walks in the curtain and wears curtain along air inlet pipe and ejects curtain, and sampling tube goes out an end of curtain and is connected with monitor with end-expiratory carbon dioxide monitoring; The contraction that can freely stretch of described screw thread tubule, the stretching shrinkage rates is about 3: 1, and the screw thread tubule other end is connected with Y tube.Can insert approximately 1-2cm of patient's bilateral nasal cavity to Y tube after pipe under the screw thread is stretched to suitable length, can monitor by the carbon dioxide waveform figure on the monitor patient's breathing situation and end-expiratory carbon dioxide level after monitor is opened.If monitor band inhalation anesthetic concentration monitor then can be monitored simultaneously the patient and be sucked and the exhalation anesthetic concentration, thereby reach the purpose of monitoring patient's inhalation anesthesia degree of depth.
In sum, inhalation anesthesia dedicated facemask of the present invention not only can be used for patient's oxygen uptake and inhalation anesthesia carries out simultaneously, can also connect the waste gas of anesthesia that negative pressure suction device breathes out the patient and automatically get rid of not contaminated operation chamber, can also be connected with the monitor with end-expiratory carbon dioxide monitoring in addition the breathing situation of directly monitoring the patient and also can monitor patient's suction and exhalation anesthetic concentration, thereby effectively control depth of anesthesia; Greatly improve inhalation anesthesia patient's safety, and medical worker's safety.
