Abstract
The utility model relates to a multifunctional air oxygen mixer comprising a proportional adjusting valve used for adjusting the air/oxygen proportion, and an air mixing chamber communicated with the proportional adjusting valve by a gas pipe; the air mixing chamber is provided with a flow adjusting valve used for adjusting and outputting the flow of an air mixture, the air mixing chamber is communicated with an air mixture outlet by the gas pipe; and the proportional adjusting valve is communicated with a pressure balance device which is used for adjusting the flow of air and oxygen so as to realize pressure balance. The multifunctional air oxygen mixer balances different pressure by adjusting the air/oxygen flow, wherein air can be supplied by using a small low-pressure pump, thus having low manufacturing cost and small noise, being more applicable to the use of the medium and small hospitals without compression air source and having complete functions, compact structure and convenient use.
Description
(1) technical field
This utility model relates to a kind of multi-functional air oxygen mixed instrument.
(2) background technology
Empty oxygen mixer is multipurpose, the multi-functional special equipment that uses various concentration oxygen source relief patients to design according to the clinical medical and nursing personal security.Existing similar products only possess single empty oxygen ratio regulatory function, and pressure equaliser is come constant pressure and formed the adjusting that realizes empty oxygen ratio with empty oxygen ratio adjusting valve by two decompressors.The shortcoming of this kind structure is that generally to need air and oxygen be the Compressed Gas of pressure greater than 0.4Mpa for pressure equaliser that this decompression realizes, and this decompression balance device structure complexity, cost is very high, compressed air has only large hospital just can provide at home, does not just reach instructions for use at middle and small hospital.And that the oxygen uptake when in the modern medical service process infant being rescued requires is very high, and pure oxygen can cause the infant retina to damage, and is difficult for again finding, therefore harm is very big.
(3) utility model content
Technical problem to be solved in the utility model is to provide a kind of employing to regulate air and oxygen flow comes equalizing pressure, thereby air source can be used the multi-functional air oxygen mixed instrument of small low-voltage pump.
Described multi-functional air oxygen mixed instrument, comprise that one is used to regulate the ratio adjusting valve of air/oxygen mixed proportion, once the mixed air vessel that appendix is communicated with ratio adjusting valve, described mixed air vessel is provided with the flow control valve that is used for regulating the output mixed gas flow, mixed air vessel is communicated with mixed gas outlet through appendix, and described ratio adjusting valve connection is used to regulate air and oxygen flow is realized pressure balanced pressure equaliser.
Further, described pressure equaliser comprises air valve pocket, oxygen valve pocket and is used for the spool of while control air valve chamber and oxygen valve pocket openings of sizes that described spool two ends connect air valve pocket and oxygen valve pocket respectively.
Further, described mixed air vessel is communicated with oxygen concentration sensor, and described oxygen concentration sensor connects the oxygen concentration display instrument.
Further, described mixed air vessel is communicated with the flow indicator.
Further, described mixed air vessel is communicated with the constant temperature humidifier through appendix, and the constant temperature humidifier is communicated with mixed gas outlet.
Further, the appendix between described mixed air vessel and the constant temperature humidifier is provided with the flow indicator.
The beneficial effects of the utility model are:
1, adopt adjusting air/oxygen flow to come the different pressure of balance, air can use the small low-voltage pump to provide, and cost is low, and noise is little, more is applicable to the use of the middle and small hospital that does not have compressed air gas source;
2, multiple functional, compact conformation, easy to use, being applicable to breathe clinically has the situation that needs oxygen therapy of obstacle to comprise nasal tube oxygen inhalation, noinvasive oxygen uptake, and uses in the neonate oxygen head-shield and in the baby incubator.
(4) description of drawings
Fig. 1 is the structural representation of the described multi-functional air oxygen mixed instrument of embodiment.
(5) specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, a kind of multi-functional air oxygen mixed instrument, comprise that one is used to regulate the ratio adjusting valve 1 of air/oxygen mixed proportion, once the mixed air vessel 2 that appendix is communicated with ratio adjusting valve 1, described mixed air vessel 2 is provided with the flow control valve 3 that is used for regulating the output mixed gas flow, mixed air vessel 2 is communicated with mixed gas outlet 4 through appendix, and described ratio adjusting valve 1 connection is used to regulate air and oxygen flow is realized pressure balanced pressure equaliser 5.
Described pressure equaliser 5 comprises air valve pocket 10, oxygen valve pocket 11 and is used for the spool 12 of while control air valve chamber 10 and oxygen valve pocket 11 openings of sizes that described spool 12 two ends connect air valve pocket 10 and oxygen valve pocket 11 respectively.
Described mixed air vessel 2 is communicated with oxygen concentration sensor 6, and described oxygen concentration sensor 6 connects oxygen concentration display instrument 7.
Described mixed air vessel 2 is communicated with constant temperature humidifier 8 through appendix, and constant temperature humidifier 8 is communicated with mixed gas outlet 4.Appendix between described mixed air vessel 2 and the constant temperature humidifier 8 is provided with flow indicator 9.
Operation principle of the present utility model is: the air of different pressures and oxygen are sent in the pressure equaliser through air plug and oxygen plug respectively, can control the flow of two kinds of gases by spool, thereby obtain the gas of two kinds of certain flow, the passing ratio control valve can obtain the empty oxygen gas mixture of different proportion again, by regulating the mist that flow control valve can obtain the different flow size, by giving the patient by mixed gas outlet after the constant temperature humidifying.The utlity model has the flow deictic function, the oxygen concentration of gas is shown in real time by the oxygen concentration display instrument.
Claims (6)
1, a kind of multi-functional air oxygen mixed instrument, comprise that one is used to regulate the ratio adjusting valve of air/oxygen mixed proportion, once the mixed air vessel that appendix is communicated with ratio adjusting valve, described mixed air vessel is provided with the flow control valve that is used for regulating the output mixed gas flow, mixed air vessel is communicated with mixed gas outlet through appendix, it is characterized in that: described ratio adjusting valve connection is used to regulate air and oxygen flow is realized pressure balanced pressure equaliser.
