Description
Art
This utility model belongs to technical field of medical instruments, especially relates to a kind of cycle gas escape type oxygen face mask.
Background technology
Oxygen face mask provides the method that can be transferred to the oxygen of besoin de respirer human lung from storage tank.Mainly contain the kinds such as the oxygen face mask of medical oxygen face shield, aviation oxygen face mask and airline passengers use, disease therapy, protection passenger and pilot are played an important role safely.The oxygen face mask that people commonly use when carrying out medical treatment is connected with oxygen tank or oxygen generating plant by air inlet pipeline usually, usual directly opening venthole on oxygen face mask, oxygen face mask ceaselessly passes into oxygen by air inlet pipeline, waste gas when being breathed by user is discharged from venthole, venthole is ceaselessly given vent to anger in this process, although the mode that this oxygen blows can ensure the oxygen purity in oxygen face mask, making user be in a kind of comparatively comfortable still this sample presentation mode needs oxygen ceaselessly to send into, oxygen consumption is huge, use cost is high.
Utility model content
For above-mentioned problem, the purpose of this utility model is, provides one periodically to carry out sending oxygen in oxygen mask, makes with the lower cycle gas escape type oxygen face mask of oxygen expense.
This utility model solves the technical scheme that its technical problem adopts: this cycle gas escape type oxygen face mask comprises case, air inlet pipe, escape pipe; The medium design of described case outer surface has inlet chamber, and air inlet pipe is communicated with the top of case by described inlet chamber, and described escape pipe is communicated with the bottom of case; Described air inlet pipe is connected with the electronics air valve that periodic switch controls air inlet pipe break-make, described escape pipe is designed with transitional cavity.
As preferentially, described air inlet pipe, escape pipe all design the bottom at described case.
As preferably, described case is also equipped with baroceptor, the detecting head of described baroceptor gos deep into the below of described casing interior, and the pore of described detecting head just to be given vent to anger position to user nostril upward, and described baroceptor is by electronics air valve described in control circui.
As preferably, the gas outlet diameter of described escape pipe is less than 10mm.
As preferably, the switch periods of described electronics air valve is less than 2.5s.
The beneficial effects of the utility model are: this cycle gas escape type oxygen face mask uses mainly for medical patient, described air inlet pipe is used for being connected with oxygen tank, by the connection of described electronics Air Valve Control air inlet pipe, described electronics air valve is periodically opened, periodically oxygen is passed into casing interior by air inlet pipe, each logical oxygen cycle is not more than on average each breathing time, and the oxygen in case can be entered transitional cavity and be discharged by the gas in transitional cavity by the amount of oxygen passed at every turn, the gas using the patient of this oxygen face mask at every turn to suck in case is so just made to be all the oxygen of high concentration, periodic break-make oxygen simultaneously, the oxygen consumption of this face shield is reduced greatly, reduce the oxygen cost of use of medical patient.
Accompanying drawing explanation
Fig. 1 is the structural representation in cycle gas escape type oxygen face mask front.
Fig. 2 is the structural representation of cycle gas escape type oxygen face mask side.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further illustrated:
As shown in the embodiment shown in fig, this cycle gas escape type oxygen face mask, it comprises case 1, air inlet pipe 2, escape pipe 3; The medium design of described case 1 outer surface has inlet chamber 11, and the top of air inlet pipe 2 with case 1 is communicated with by described inlet chamber 11, and described escape pipe 3 is communicated with the bottom of case 1; Make the gas passing into case 1 enter from case 1 top like this, bottom is discharged, and can form smooth air-flow, be convenient to the displacement of gas.Described air inlet pipe 2 is connected with the electronics air valve 4 that periodic switch controls air inlet pipe 2 break-make, described escape pipe 3 is designed with transitional cavity 5.
This cycle gas escape type oxygen face mask uses mainly for medical patient, and described air inlet pipe 2 is used for being connected with oxygen tank, passes into oxygen by the high pressure oxygen in oxygen tank in case 1; Described escape pipe 3 is directly communicated with outside atmosphere.The connection of air inlet pipe is controlled by described electronics air valve 4, described electronics air valve 4 is periodically opened, oxygen is passed into case 1 intercycle property by air inlet pipe 2, each logical oxygen cycle is not more than on average each breathing time, and the oxygen in case 1 can be entered transitional cavity 5 and be discharged by the gas in transitional cavity 5 by the amount of oxygen passed at every turn, described crossing in cavity 5 loads the air of user exhalation and the gaseous mixture of oxygen, like this can by the high-concentration oxygen in case 1 and extraneous snubber contact, the high-concentration oxygen in case 1 is prevented to be neutralized, the gas so just making to use the patient of this oxygen face mask at every turn to suck in case 1 is all the oxygen of high concentration.Periodic break-make oxygen, makes the oxygen consumption of this face shield greatly reduce, reduces the oxygen cost of use of medical patient simultaneously.
As depicted in figs. 1 and 2, described air inlet pipe 2, escape pipe 3 all design in the bottom of described case 1.The arrangement of such convenience parts, and the access of oxygen pipeline.
As depicted in figs. 1 and 2, described case 1 is also equipped with baroceptor 6, the detecting head 61 of described baroceptor 6 gos deep into the below of described case 1 inside, the pore of described detecting head 61 just to be given vent to anger position to user nostril upward, and described baroceptor 6 is by electronics air valve 4 described in control circui.Baroceptor 6 is for measurement gas pressure, when the user breath of face shield, the air pressure at detecting head 61 place of described baroceptor 6 uprises, described baroceptor 6 sends detectable signal and is opened by electronics air valve 4, connection delay shut-off circuit on described electronics air valve 4 simultaneously, the late release of described electronics air valve 4, in the opening time of electronics air valve 4, described case 1 and cushion chamber 5 gas complete the discharge of gas just, what make this face shield like this puts oxygen cycle and synchronized with breath, reduce further oxygen consumption.
The gas outlet diameter of described escape pipe 3 is less than 10mm.The contact of cushion chamber 5 space outerpace can be reduced like this, the air in cushion chamber 5 is not easily neutralized.
In face shield, also can not use described baroceptor 6, but use the replacement of the circuit of described electronics air valve 4 periodic switch, when specific design parameter, the switch periods of described electronics air valve 4 is less than 2.5s.The frequency that people breathe is about the respiratory frequency of normal adult when calmness and is about 16 ~ 20 times per minute, women comparatively slightly fast 2 ~ 3 times of male.So each breathing cycle is about between 2.5s to 3s, described electronics air valve 4 cycle design below 2.5, just can ensure the user of this face shield aerobic process all once between the breathing of twice, what ensure that user sucks at every turn is all the oxygen of higher concentration.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
