CN2822686Y - Controllable mask with filter for reusing exhaled air - Google Patents

Abstract

The utility model discloses a controllable mask for filtering and reusing exhaled air, which is composed of a mask body 1, an inflation sealing pad 2, a tie 3, an air inlet pipe 4 and a three-way valve 5, wherein the three-way valve 5 is provided with an oxygen pipe joint 6 and a carbon dioxide reusing pipe joint 7; the lower side of the mask body 1 is provided with an exhalation flow pipe 8 which is inserted into the bottom of a sealing filtration bottle 9 through a rubber pipe 14; an insertion pipe 10 on the upper part in the filtration bottle 9 is connected with a miniature gear pump 12 through a corresponding rubber pipe 11; an air outlet of the miniature gear pump 12 is fixed with a flow quantity and diversion control valve 13. Because the controllable mask for filtering and reusing exhaled air integrates the functions of exhalation filtration, reusing quantity, pumping flow diversion and quantitative oxygen conveying, the utility model not only can control quantitative reusing quantities of exhalation carbon dioxide for patients, but also can carry out sterilization and filtration for reusing carbon dioxide which is inhaled so as to prevent further infection of diseases. Meanwhile, the utility model can also prevent return breath of carbon dioxide so as to reduce the occurrence of a dead cavity effect.

Description

Exhale and filter the controlled face shield of reverting to take drugs

Technical field

The utility model relates to a kind of medicine equipment, and the controlled face shield of reverting to take drugs is filtered in particularly a kind of expiration that is applicable to the overventilation patient.

Background technology

Overventilation is meant that expiration is excessive.The overventilation patient often runs in neurology department, emergency department, comprises central overventilation, disease overventilation.Overventilation patient's principal character is that respiratory rate is too fast, makes excreting of hypercapnia, makes human body generation respiratory alkalosis, and then cause low calcium, low magnesium, and the lighter's tetany, numb limb, weight person can cause epilepsy, serious acid-base imbalance, even threat to life.Excessive for preventing expiration, the method of taking at present is with paper bag or polybag mouth and nose to be covered, patient expired carbon dioxide is sucked again, though this method is simple, but also exist significantly not enough: the one, because the carbon dioxide of breathing out often carries the germs of a disease, particularly for the patient with spreading venereal diseases, expiratory air sucks again again, can increase the weight of conditions of patients; The 2nd, the carbon dioxide of reverting to take drugs again is difficult to the control amount of reverting to take drugs, so result of treatment is undesirable; The 3rd, muzzle is covered, though in all sealing realization malleation artificial ventilation, patient for acute exacerbation is the most frequently used, so that suitable ventilation support to be provided, change the oxygenate function, alleviate the load of the heart and breathing muscle, but when face shield is ventilated, owing to exist carbon dioxide to return to breathing, can cause tangible dead space effect, influence the effect that it lowers carbon dioxide level.

Summary of the invention

The purpose of this utility model is to provide a kind of amount of reverting to take drugs that not only can control patient expired carbon dioxide, and the gas that gives off carbon dioxide carried out reverting to take drugs after the filtration treatment again, prevent because of the carbon dioxide of reverting to take drugs further infects, also prevent that the expiration of dead space effect generation from filtering the controlled face shield of reverting to take drugs simultaneously.

For reaching above purpose, the technical scheme that the utility model adopted is: the controlled face shield of reverting to take drugs is filtered in this expiration, by mask body, blown-in-place blood gasket, frenulum, air inlet pipe, triple valve constitutes, blown-in-place blood gasket sticks on the mouth of mask body along last, triple valve is fixed on the outer end of air inlet pipe, in the inner inserting surface cover body of air inlet pipe, its position is corresponding with nose portion, on triple valve, establish oxygen tube junction and filter the carbon dioxide pipe joint of reverting to take drugs, it is characterized in that establishing the expiration effuser at the downside of mask body, the bottom in the filtering flask that seals is inserted in the sebific duct lower end that is connected with the expiration effuser, filtering flask internal upper part in sealing is provided with intubate, intubate is connected with the air inlet of miniature gears pump by corresponding sebific duct, fixing the flow shunting valve on the gas outlet of miniature gears pump, a gas outlet of flow shunting valve is by corresponding sebific duct and filter the carbon dioxide pipe joint of reverting to take drugs and be connected, another gas outlet was communicated with outer Jie, in working order down, be provided with disinfecting liquid in the filtering flask, patient expired carbon dioxide gas enters the sterilization that carries out disinfection in the interior disinfecting liquid of filtering flask, because the swabbing action of miniature gears pump, the top of filtering flask is negative pressure state, so the carbon dioxide gas of breathing out also is relatively easy to enter in the disinfection of filtering flask, the carbon dioxide that has filtered, under the promotion of gear pump, by the flow shunting valve, a part enters in the triple valve by sebific duct, with oxygen mix, in the entering surface cover body, make the patient both suck oxygen, reverted to take drugs again carbon dioxide after filtering, the carbon dioxide of excessive part flows out from the gas outlet that the flow shunting valve is in communication with the outside.The utility model is to implement by following measure also: described flow shunting valve, by valve body, the runner partition wall, handler, quantitatively flow distribution plate constitutes, the runner partition wall is divided into two chambeies with the exit of valve body, a chamber connects sebific duct by corresponding gas outlet, another chamber is in communication with the outside by corresponding gas outlet, quantitatively flow distribution plate and handler are fixed, rotation by handler, can regulate the position of quantitative flow distribution plate, on the panel of valve body, also be provided with quantitative stepping sign, can be divided into A, B, the C third gear, when handler points to the A shelves, the flow that enters the carbon dioxide gas after the filtration of triple valve is the 100ml/ branch, patient when being applicable to respiratory rate less than per minute 40 times, when the B shelves, the flow that enters the carbon dioxide gas after the filtration of triple valve is the 200ml/ branch, be applicable to the patient of respiratory rate in 40-70 time/minute scope, when the C shelves, the flow that enters the carbon dioxide gas after the filtration of triple valve is the 300ml/ branch, be applicable to the patient that respiratory rate is divided greater than 500ml/ greater than 40 times/minute and tidal volume, by control, prevent that gas concentration lwevel is too high, dead space appears, while also makes each air-breathing all can have oxygen and filtration carbon dioxide participation suction, prevents carbon dioxide narcosis.When using the utility model, mask body is fixed on patient's snout with frenulum, and the oxidation tube joint on the triple valve is connected with the oxygen cathete of oxygen cylinder, and regulate the oxygen therapy amount be the 2-4 liter/minute, according to the position of patient respiratory frequency and tidal volume adjustment flow shunting valve, can normally use.

The beneficial effects of the utility model are: compare with the oxygen face mask that present overventilation patient uses, because this face shield collection call gas filters, reverts to take drugs quantitatively, pumping is shunted, quantitatively sent oxygen in one, so can not only control patient to a certain amount of amount of reverting to take drugs that given off carbon dioxide, and the carbon dioxide of reverting to take drugs that sucks has passed through the disinfection filtration, prevented the further infection of disease, prevented from also simultaneously that carbon dioxide from returning to breathe and cause the generation of dead space effect.
