Abstract
The utility model provides a synchronous pressurized breathing face (nose) cover, which is characterized in that: the supporter of air inlet of the face (nose) cover is connected sealingly with a chargeable airbag, the airbag is provided with two charge nozzles, an air cavity is built in the airbag, the face (nose) cover is tightly abutted against the face (nose) by a synchronous charge head belt via the head belt fixing sleeve. The utility model effectively avoids the putrescence of skin on the face due to oxygen lack, thereby improving the compliance of patients on the face (nose) and enlarging the adaptability of noninvasive ventilation.
Description
Technical field
This utility model relates to the ventilation utensil of a kind of hospital rescue, particularly a kind of synchronous pressure breathing face (nose) cover.
Background technology
The later stage seventies and the initial stage eighties, the positive airway pressure technology applying clinical that carries out through face shield or nose cup.The quality that is limited to face shield at that time is not good enough, and style is single not to match, and patient's toleration is relatively poor, can only use in the gap.The effect that improves oxygenate still can, but reduce partial pressure of carbon dioxide (paCO2), the effect that increases ventilation is undesirable.Along with the progress of materialogy, the material of making face shield also ceaselessly improves, and what use at present is the softish silica gel of quality.Style is on the increase, and the shape of face shield more meets people's facial anatomical features, and sealing property strengthens.Existing bibliographical information be exclusively used in the modified model full facepiece mask of noninvasive positive pressure ventilation (NIPPV).It has the advantage of less gas leakage and patient comfort with the face shield of standard or nose cup comparison.And face shield has the trend of individuation, as: the face shield that is specifically designed to the agomphosis patient is arranged.The appearance of nose cup has obviously improved patient's compliance.The dead space that nose cup increased is less, and the less fear of being enclosed that causes, allows expectoration and ingests and needn't pluck nose cup complication such as reduce that mistake is inhaled, suffocated.Mortimore, IL is divided into two groups with the sleep apnea syndrome patient and uses nose cup and face shield to continue the report positive airway pressure respectively, relatively its curative effect and side effect, the result shows: patient obviously will get well than face shield the compliance of nose cup, but owing to the gas leakage of nose cup per os influences therapeutic effect, thereby the improvement of mask designs is imperative.Be the sealing of increase face (nose) cover, smear paste or the clean dressing of padding at face (nose) cover pressure place when using the noinvasive ventilation clinically, with the gas leakage of the dough-making powder that reduces friction (nose) cover.The improved face shield of Chen Rongchang has been eliminated the RB of carbon dioxide to a certain extent.But come the research of the sealing comfortableness of raising face (nose) cover not appear in the newspapers as yet by the method for synchronous pressurization.
Summary of the invention
The purpose of this utility model is intended to overcome the deficiencies in the prior art and provides the pressurization of a kind of (nose) and breathing synchronous, avoids the gas leakage of patient's skin of face ischemic necrosis dough-making powder (nose) cover, improves the synchronous pressure breathing face (nose) of giving first aid to effect and covers.
The purpose of this utility model is achieved in that
A kind of synchronous pressure breathing face (nose) cover, comprise headband fixed cover hook 1, it is characterized in that the supporter 3 of face (nose) cover air inlet is airtight is connected in inflatable air bag 4, air bag 4 is provided with two inflations (losing heart) and chews 5, air bag 4 built-in gas gallbladders 10 are inflated headband 6 synchronously and through headband fixed cover hook 1 face (nose) cover are closely attached on face (nose).
---(letting out) gas that fills of described synchronous inflation headband 6 is chewed 9 and is connected with synchronous pressurized control gas circuit.
---(letting out) gas that fills on the described air bag 4 is chewed 5 and also is connected with synchronous pressurized control gas circuit.
This utility model is practical through the clinical verification proof, avoids patient's skin of face ischemic necrosis effectively, has improved the compliance of patient opposite (nose) cover, has enlarged the indication of noinvasive ventilation.

The specific embodiment
Face (nose) cover inflation headband is designed to type inflatable.When respirator is in inspiratory phase, electromagnetic valve 1DT conducting, 2DT closes, and air pump plays its capsule to respiratory surface (nose) cover or the quick punching press of inflation headband, makes the leakproof of combining closely of face (nose) cover and patient's face; Work as patient exhales, when respirator was in expiratory phase, electromagnetic valve 1DT closed, the 2DT conducting, gas flows into atmosphere in the air bag, and face (nose) cover or the pressure release of inflation headband air bag are lax, with of the extruding of elimination face (nose) cover, avoided the facial long-term stressed discomfort of pressing generation of patient to patient's face.The tensioning degree of face (nose) cover or inflation headband is by the decision of the gas pressure in the air bag, and atmospheric pressure value is regulated by overflow valve, determines to rush down the pressure threshold value according to the result of zoopery and clinical trial.
Be equipped with the synchronous induction element of diaphragm contact
Install a simple conductive film element additional at the respirator escape pipe, as shown in Figure 5, when respirator was in inspiratory phase, diaphragm was impacted by positive draft, and the pressurized motion is connected with stationary contact, circuit turn-on, actuating coil HC is charged, coil auxiliary contact 1HC catalyst closure (shown in Figure 6), and HQ is charged for inflation electromagnetic valve 1DT switch motion coil, the 1DT conducting, the electromagnetic valve of pressure release simultaneously 2DT closes.Pressurized gas is to face (nose) cover or the pressurising of inflation headband; Otherwise when respirator was in expiratory phase, diaphragm automatically springed open, and separated with static contact, Fig. 5 down circuitry, coil HC dead electricity, coil auxiliary contact 1HC catalyst disconnects, inflation electromagnetic valve 1DT closes, the electromagnetic valve of pressure release simultaneously 2DT conducting, face (nose) cover or inflation headband releasing pressure automatically.Being subjected to the pressuring film plate circuit part is 6 volts of low-voltage dc circuits, and to avoid frequent contact, at disconnected fashionable generation spark, 110 volt AC power can be used in switch motion coil point road, make switch motion strong rapidly.
Also can directly control two electromagnetic valves of synchronous pressurized control gas circuit during enforcement with the logical signal of respirator.For preventing that face shield from losing heart back stiff dough cover main body vertical compression in face, with the constant internal air bladder 10 of the built-in air content of face cushion.
