Description

Resuscitation mask oxygen connection

Technical field

The utility model is related to technical field of medical instruments, more particularly to a kind of resuscitation mask oxygen connection.

Background technology

Artificial resuscitation adapter functions currently used in the market are had nothing in common with each other, but all have most basic function, i.e. handle Oxygen in oxygen or air is entered patient's requisite oxygen air pressure in the lung of patient by extruding air storage bag.Such equipment is general There are following a few classes：

(1) oxygen connection, i.e. control of breathing valve are connected by mask, but the control valve is only equivalent to a gas company Equipment is connect, only there is unidirectional air guiding function, without degassing function, equivalent to one check valve.

(2) existing air guiding function, while the carbon dioxide that patient breathes out can also be discharged by exhaust passage, that is, is vented work( Can, equivalent to two-way control of breathing valve.

(3) two-way control of breathing valve still has some defects., may if such as emergency staffs experience is not very abundant Because the gas atmosphere for being pressed into patient lungs is too high, the carbon dioxide ratio for causing patient to breathe out is very low, causes doctor's erroneous judgement trouble Person is dead and causes malpractice.So in an inlet end pressure-reducing valve in parallel for the two-way control of breathing valve, working as air inlet When air pressure is higher than 40CM water columns, the gas of inlet end just leaks, and reduces the malpractice caused by air inlet air pressure is too high.

(4) some defects are still had in the two-way control of breathing valve of inlet end pressure-reducing valve in parallel.Due to no pressure Display function, operating personnel can not judge to be pressed into the air pressure size of patient lungs.Therefore, occur in that on the market in inlet end at present Pressure-reducing valve in parallel and the two-way control of breathing valve with visualization admission pressure display function.The usual visualization function is to enter One piston barometer of gas end parallel connection, such operating personnel can see that the gas of press-in patient lungs at any time when rescuing patient Press size.But the visualization device still has some defects, due to piston during movement quickly, operating personnel are difficult Read accurate, do not meet the custom of mankind's reading, so the barometrical actual use of piston and little, reading is not directly perceived.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of resuscitation mask oxygen connection, can accurately show press-in The atmospheric pressure value of patient lungs, and convenient observation.

In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：

On the left of a kind of resuscitation mask oxygen connection, including air inlet port, expiration port and mask port, the air inlet port Include the connection worm screw, institute in the middle part of Flexible film, worm screw and dial plate barometer, the Flexible film in connection cavity, the cavity State and pointer is provided with inside dial plate barometer, the pointer is connected to the connection face below the top of the worm screw, the cavity Cover the connection expiration port on the left of port, the mask port.

Further, it is provided with guide valve below the cavity.

Further, the vertical section of the guide valve is " V " shape.

Further, the guide valve is check valve.

Further, it is provided with relief valve above the air inlet port.

Further, the relief valve is auto-manual system.

Using above-mentioned technical proposal, due to being provided with dial plate barometer and pointer in cavity, oxygen enters from air inlet port It is fashionable, the Flexible film of inside cavity can be driven to move, Flexible film driving worm screw rotates, and the pointer above worm screw will point to dial plate gas The upper corresponding atmospheric pressure value of pressure meter, operating personnel can intuitively read the atmospheric pressure value of press-in patient lungs very much, and make in time Adjustment, makes patient obtain most rational air pressure, while the atmospheric pressure value shown on dial plate barometer is exact value, can effectively improve and rob Rescue efficiency and precision, reduction rescue malpractice.

In figure, 1- air inlet ports, 2- expiration port, 3- mask ports, 4- relief valves, 5- dial plate barometers, 6- pointers, 7- Worm screw, 8- Flexible films, 9- guide valves, 10- cavitys.

Embodiment

Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that Explanation for these embodiments is used to help understand the utility model, but does not constitute to restriction of the present utility model.This Outside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not constitute conflict each other It can just be mutually combined.

As shown in Figure 1, Figure 2 and Figure 3, resuscitation mask oxygen connection disclosed in the utility model, including air inlet port 1, exhale Gas port 2, mask port 3, relief valve 4, dial plate barometer 5, pointer 6, worm screw 7, Flexible film 8, guide valve 9 and cavity 10.

Include Flexible film 8, worm screw 7 and dial plate in the left side connection cavity 10 of air inlet port 1 for inputting oxygen, cavity 10 Barometer 5, the middle part connecting worm 7 of Flexible film 8, the inside of dial plate barometer 5 is provided with pointer 6, and pointer 6 is connected to the top of worm screw 7, The lower section of cavity 10 is connected to cover the mask port 3 of patient facial region's mask, and the left side of mask port 3 connection expiration port 2 is exhaled Port 2 is used for the carbon dioxide for discharging patient's exhalation.Oxygen enters fashionable from air inlet port 1 needed for patient, and the oxygen of entrance drives Flexible film 8 inside dynamic cavity 10 is moved, and the driving worm screw 7 of Flexible film 8 rotates, and the pointer 6 of the top of worm screw 7 will point to dial plate air pressure Corresponding atmospheric pressure value on meter 5.

The lower section of cavity 10 is provided with guide valve 9, and the vertical section of guide valve 9 is " V " shape and is check valve.Needed for patient When oxygen enters cavity 10 by air inlet port 1, it can be opened on the right side of the " V " shape of the guide valve 9 of the lower section of cavity 10, oxygen passes through face Cover port 3 enters patient lungs, after patient takes a breath, and is closed on the right side of the " V " shape of guide valve 9, and left side is opened, patient's exhalation Carbon dioxide is discharged from expiration port 2, so completes a breath cycle.Guide valve 9 make it that the oxygen of conveying can only be unidirectional Ground is conveyed into mask port 3, and the carbon dioxide of patient's exhalation can not then mix the oxygen hose connected into air inlet port 1 Group, it is ensured that the degree of purity of conveying oxygen, improves treatment quality.Meanwhile, the carbon dioxide that guide valve 9 breathes out patient can only be unidirectional Ground is discharged to the outside from expiration port 2, and outside air enters in mask and causes the drop of oxygen concentration when can prevent patient breaths It is low.

In the present embodiment, the top of air inlet port 1 is provided with relief valve 4, and relief valve 4 is auto-manual system.In advance in dial plate gas One fixed value (generally 40CM water columns), when patient lungs' atmospheric pressure value is more than the fixed value, relief valve 4 are set on pressure meter 5 Can releasing pressure automatically, the gas atmosphere of reduction patient lungs, reduction malpractice caused by air inlet air pressure is too high.Certainly, for Experience very abundant medical personnel, if they be not in when rescuing patient be pressed into patient lungs gas atmosphere it is too high Situation, resuscitation mask oxygen connection of the present utility model can also without set relief valve 4, the present embodiment be only to provide one it is excellent Select scheme.

Embodiment of the present utility model is explained in detail above in association with accompanying drawing, but the utility model is not limited to be retouched The embodiment stated.For a person skilled in the art, it is right in the case where not departing from the utility model principle and spirit These embodiments carry out a variety of change, modification, replacement and modification, still fall within protection domain of the present utility model.
