Abstract
The utility model discloses an adjustable inhaled air quantity oxygen mask, comprising a mask body 1, a three-way pipe 2 and a fastening belt 3, wherein the lower end port of the three-way pipe 2 is screw connected with the mask body 1, the left end port of the three-way pipe 2 is equipped with an oxygen pipe jointer 4 connected with the oxygen pipe, and the right end port of the three-way pipe 2 is connected with an upper folded bellow 5. The adjustable inhaled air quantity oxygen mask not only has simple structure and convenient usage, but also can adjust and control the repeated inhaling quantity of the CO2 inhaled by the patient, and increases the therapy effect.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and particularly a kind of adjustable tolerance oxygen face mask of reverting to take drugs is applicable to Hyperventilated patient.
Background technology
In hospital neruosurgery, emergency department, intensive care unit(ICU), often run into Hyperventilated patient, comprise central Hyperventilation, hysteric Hyperventilation etc.Clinical manifestation is that respiratory frequency is too fast, makes that carbon dioxide is excessive to excrete, and body generation respiratory alkalosis causes low calcium, low magnesium then, the lighter's tetany, numb limbs and tense tendons, and weight person can cause epilepsy, serious acid base imbalance, threat to life.Clinical solution commonly used is at present: utilize paper bag or plastic bag that mouth and nose are covered, make patient expired CO
2Part repeats to suck, but this method can not be regulated the patient expired CO of control according to state of an illness needs
2The repetition suction volume of gas is so therapeutic effect is relatively poor.
Summary of the invention
The purpose of this utility model is to provide a kind of scalable to control patient expired CO
2The repetition suction volume of gas is to improve the adjustable tolerance oxygen face mask of reverting to take drugs of therapeutic effect.
For reaching above purpose, the technical scheme that this utility model adopted is: this is adjustable tolerance oxygen face mask of reverting to take drugs, constitute by mask body, tee T, frenulum, the lower port of tee T and mask body are with being threaded, the left port of tee T is established the oxygen catheter joint that is connected with oxygen catheter, connect folded formula bellows, patient expired CO in the right output port of tee T
2The part oxygen of gas and input can when patient inhales, can make the gas in the folded formula bellows suck again, so also sucked portion C O again in folded formula bellows inner accumulated
2Gas, flexible by folded formula bellows changes the volume of folded formula bellows, itself and patient's respiratory frequency and tidal volume adapted, to reach patient expired CO
2The purpose that part sucks again.This utility model is also implemented by following measure: described folded formula bellows are that plastic material is made, for cylindric, cylindrical wall is a folded wall, the right side is the plectane face, the middle part is provided with the circular open of outside ventilation, the left side also is the plectane face, and the middle part is provided with and the tee T right output port mouth of pipe that is threaded, and establishes the collapsing length fixed mount in the cylindrical wall outside; Described collapsing length fixed mount is that four cross bars are formed, the right-hand member of four cross bars all is fixed on the stretching annulus, the left end of four cross bars all is fixed on the folded formula bellows left end panel, on a cross bar of upside, establish the collapsing length positioning, the collapsing length positioning can be established A, B, C third gear, the A shelves are for folded formula bellows volume is 100ml, the patient when being applicable to respiratory frequency less than per minute 40 times; The B shelves are for folded formula bellows volume is 200ml, are applicable to the patient of respiratory frequency in 40-70 time/minute scope; The C shelves are for folded formula bellows volume is 300ml, are applicable to respiratory frequency greater than 40 times/minute and the tidal volume patient greater than 500ml, and the circular open diameter on the folded formula bellows right side is 25mm, by circular open and atmospheric pressure maintenance balance, prevents CO
2Excessive concentration, gas are in suction process, and the air-flow center can be introduced into alveolar, when flow velocity is fast, the tolerance that the air-flow center enters alveolar also increases relatively, and when excessive ventilation, inspiratory flow rate speeds, each air-breathing all can have the part fresh air to enter bellows, and enter alveolar, so CO can not take place
2Anesthesia, the oxygen-supplying amount of oxygen catheter be the 2-4 liter/minute, can make to suck the gas oxygen concentration and reach 24-28%, be higher than aerial oxygen concentration, reduce the irritability of carotid sinus and chemoreceptor of aortic body, and then improve Hyperventilated symptom.
When using this utility model, face shield is fixed in patient's snout with frenulum, oxygen catheter connections in, adjusting oxygen therapy amount be the 2-4 liter/minute, the collapsing length of folding the formula bellows according to patient respiratory frequency and tidal volume adjustment gets final product.
The beneficial effects of the utility model are: the CO patient expired with the Hyperventilation of present application
2The method of reverting to take drugs is compared, and is not only simple in structure, easy to use, and scalable is controlled patient expired CO
2The repetition suction volume of gas improves therapeutic effect.
