Abstract

The invention discloses a critical ill patient respirator. In a first-aid site, the lung myoplegia patient who loses autonomous respiration capacity can lose life in short time if not forced to breathe. The respirator can be used for sending air of certain pressure into the lung to meet the requirements of the human body for oxygen inhalation and oxygen exchange. The price of a general respirator is more than ten thousand yuan, but the price of the critical ill patient is only several hundred yuan. Thus, the critical ill patient respirator is low in cost. Furthermore, the critical ill patient respirator is reliable and safe and can bring convenience to low-income patients in poverty-stricken areas. The critical ill patient respirator is composed of oxygen-bearing compressed air, a pressure reducing valve, an overflowing valve, a respirator control valve and a respirator connector.

Description

A kind of critical patient's respirator

Technical field

The present invention relates to a kind of critical patient's respirator, belong to medical apparatus and instruments.

Background technology

Some patient's lung myoparalysis, has lost the ability of autonomous respiration, and pulmonary cannot oxygen uptake, as not forced breathing, the short time will lose one's life, the effect of respirator is exactly with its built-in compressed air ，Xiang pulmonary, to transmit the air of certain pressure, to meet human body oxygen uptake and to change oxygen demand.

The common peasant Shao Da in one, Shao Lou village, great Xu town, east, Xuzhou is diagnosed as progressive muscular atrophy, from walking to, be paralyzed in bed, 21 year old that year, he has lost the ability of autonomous respiration substantially, his lip, ear, it is livid purple that cheek will become, over 3 years, father and mother keep watch with him in turn, 24 hours every days, couple of seconds once, the artificial respirator that has with the hands served as him, the respirator because they cannot afford, more than 10,000 yuan of general respirator market price, cheap also wants eight or nine thousand yuan, if there are a kind of thousand yuan to supply poverty-stricken area low income patient with interior respirator, how that is.

Summary of the invention

For above present situation, a kind of critical patient's respirator of the present invention only needs the cost of 200 yuan, and 500 yuan of market prices can be bought one; The object of the present invention is achieved like this: it is by forming containing oxygen compressed air, air relief valve, overflow valve, respiratory organ control valve, respiratory organ interface.

Wherein containing oxygen compressed air: the mixing air of oxygen content 20%, is stored in pressure vessel;

Air relief valve: pressure vessel mesohigh gas is reduced to low pressure adjustable;

Overflow valve: injure patient while preventing air relief valve operation irregularity, by over-pressure gas bypass;

Respiratory organ control valve: when valve block is closed, containing the oxygen air pulmonary of making a gift to someone, valve block is opened the gas Natural excrement of Shi， pulmonary, reach with atmospheric pressure balance till;

Respiratory organ interface: it is a seal closure, safe will send into pulmonary containing oxygen air.

Accompanying drawing explanation

Fig. 1, the block diagram of a kind of critical patient's respirator of the present invention operation principle, also as Figure of abstract;

Fig. 2, the principle schematic of a kind of critical patient's respirator of the present invention.

Specific embodiments

Below in conjunction with accompanying drawing, one embodiment of the present of invention are described in detail:

As described in Figure 1, it is by forming containing oxygen compressed air, air relief valve, overflow valve, respiratory organ control valve, respiratory organ interface.

As described in Figure 2, it by be stored in pressure pan 1 containing oxygen compressed air, through pressure piping 12 air relief valve 2 of making a gift to someone, through post-decompression, containing oxygen air, enter low pressure pipeline 13, be 10-20 centimeter water column containing the compressed-air actuated air pressure of oxygen in low pressure pipeline 13, then after air filter 3, the end that enters low pressure pipeline 11 forces air-breathing through respiratory organ interface 10 for patient, respiratory organ interface 10 is the soft covers of hemispherical, is buckled on patient's face 7, and nostril 8 and oral cavity 9 covers is tight and air tight; Low pressure pipeline 11 these sections are established two bypass ，Yi roads and are connect overflow valve 4, and when in low pressure pipeline 11, air pressure surpasses alarm pneumatic, overflow valve 4 is opened automatically, makes unnecessary gas bypassing; An other bypass is respiratory organ control valve 5, and the closure of valve block 6 wherein and unlatching are subject to the programme-control of electromagnetic relay, and electromagnetism valve block 6 is breathing process when closed, and electromagnetism valve block 6 is exhalation process while opening, and valve block is opened the gas Natural excrement of Shi， pulmonary; Inspiratory/expiratory: be generally 1:1.5-2, respiratory frequency: 30～40 beats/min of babies, adult 16-20 beat/min.

Claims

1. critical patient's respirator, it is by containing oxygen compressed air, air relief valve, overflow valve, respiratory organ control valve, respiratory organ interface forms, it is characterized in that: it by be stored in pressure pan (1) containing oxygen compressed air, through pressure piping (12) air relief valve (2) of making a gift to someone, through post-decompression, containing oxygen air, enter low pressure pipeline (13), again through air filter (3) afterwards, the end that enters low pressure pipeline 11 forces air-breathing through respiratory organ interface 10 for patient, respiratory organ interface (10) is the soft cover of hemispherical, be buckled on patient's face (7), nostril (8) and oral cavity (9) are covered tight and air tight, this section of low pressure pipeline (11) is established two bypass ，Yi roads and is connect overflow valve (4), and when in low pressure pipeline (11), air pressure surpasses alarm pneumatic, overflow valve (4) is opened automatically, makes unnecessary gas bypassing, in addition-bypass is respiratory organ control valve (5), and the closure of valve block wherein (6) and unlatching are subject to the programme-control of electromagnetic relay, and electromagnetism valve block (6) is breathing process when closed, and electromagnetism valve block (6) is exhalation process while opening.
