Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a facial oxygen mask,

The present invention relates to a facial oxygen mask for implementing a high-concentration oxygen administration, and more particularly, to a facial oxygen mask for administering high-concentration oxygen, Can be about facial oxygen mask.

The facial oxygen mask is a device for improving the respiratory condition of a patient by supplying a high concentration of oxygen to the patient. Facial oxygen masks are widely used and frequently used in general wards as well as facilities (ambulances, emergency rooms) for treating emergency patients.

These facial oxygen masks are classified into 're-breathing type' that can administer high-concentration oxygen to patients and 'simple type' that can not administer high-concentration oxygen (ie, re-breathing type). Since a nasal prong cannula is used for patients requiring low-dose oxygen, the use of a facial oxygen mask presupposes a medical judgment that the patient needs to administer a higher oxygen concentration.

For this reason, facial oxygen masks used in medical field are used more frequently than 'simple type' for 're-breathing type'. The 're-breathing type' facial oxygen mask is said to theoretically be able to supply patients with a high concentration of oxygen close to 100% (commonly referred to as 'high concentrations of oxygen', more than 80%). For this purpose, 100% oxygen accumulated in the storage bag must flow into the patient's airways and lungs when the patient is inhaled, without the presence of air outside the mask. When the patient is breathing, To be maximally discharged out of the mask so as not to be sucked in again. For this reason, the anti-respiratory face oxygen mask includes oxygen storage bags and one-way valves for air interception.

However, although the respiratory protection type masks currently used in practice have a one-way valve for venting, a one-way valve for intake, and an oxygen storage bag, the one-way valves do not operate correctly, I can not. In addition, the storage bag is not easily inflated by the oxygen introduced during the patient's breath and is not easily compressed when a negative pressure is applied to the mask during the inspiration of the patient, There is a limit in achieving the original purpose of supplying oxygen at a high concentration. In other words, most products sold as 're-breathing type' masks have very little re-breathing protection due to functional defects of the storage bag and one-sided valve, and are merely functions of a 'simple' mask.

For this reason, in practice, tracheal intubation or similar airway securing technique, which may be unnecessary for patients who need oxygen at a high concentration, is being applied. These invasive airway assurance techniques cause serious side effects and complications Have.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved facial oxygen mask for strictly preventing a patient's re-breathing.

It is another object of the present invention to make use of a face oxygen mask suitable for a patient's condition and a face shape by proposing various forms of a face oxygen mask for strictly preventing recurrence.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

1 is a front view of a face oxygen mask according to an embodiment of the present invention. The face oxygen mask 50 according to one embodiment includes a storage bag 100 in which a high concentration of oxygen to be supplied to a patient is stored, a path in which oxygen at a high concentration to be supplied to the patient from the storage bag 100 is moved A second communication part 120 which is a path through which the gas discharged from the patient's lung and airway moves during the breathing of the patient, and a path through which high-concentration oxygen is introduced into the storage bag 100 The emergency air inflow pipe 140 and the emergency air inflow pipe 140 which are separate and separate paths when the patient's respiration is weak and the air is additionally supplied to the patient are connected to the first communication part 110 And an engaging portion 145.

In addition, the first valve 152 and the second valve 156, which move in accordance with the patient's breath, are positioned in the first communication part 110 of the face oxygen mask 50, The first and second plate films 154 and 158 are moved.

Next, the operation between the above-described configurations according to the patient's breathing will be described in detail. First, a high concentration of oxygen is continuously supplied from an external oxygen supply device to the storage bag 100 through the oxygen inflow pipe 130. The face oxygen mask 50 covers the nose of the patient, (10) is attached to the face of the patient.

During inspiration of the patient, the first valve in the first communication part 110 moves from the position 152 to the position 156, whereby the high concentration of oxygen stored in the storage bag 100 is supplied to the patient's nose. At this time, the second valve plate in the second communication part 120 moves from the position 154 to the position 158 and closes the second communication part 120 according to the movement of the first valve plate. That is, the first plate and the second plate are fixed while maintaining a predetermined angle, and the first plate and the second plate are moved together according to the inspiration of the patient, and the first and second communicating parts 110, Open and close. The air existing outside the face oxygen mask can be prevented from being supplied again through the mouth of the patient as the second communication portion 120 is closed.

Subsequently, at the time of expiration of the patient, the first valve in the first communication part 110 moves from the position 156 to the position 152 again, whereby the first communication part 110 is closed. At the same time, the second valve plate of the second communication part 120 moves from the position 158 to the position 154, and the air released by the patient is discharged to the outside through the second communication part 120. At this time, the first communication part 110 is closed by the first valve film 152, and the high concentration of oxygen flowing through the oxygen inflow pipe 130 is stored in the storage bag 100.

The emergency air inlet pipe 140 is connected to the first communication unit 110 through the coupling unit 145. The coupling unit 145 automatically connects the first communication unit 110 to the first communication unit 110 when a pressure equal to or greater than a threshold value is sensed, As shown in FIG. For example, when the patient is breathing normally, the coupling part 145 connects the first communication part 110 and the emergency air inflow pipe 140 so that only the high concentration oxygen stored in the storage bag 100 is supplied to the patient . On the other hand, if the patient's respiration is very bad, oxygen stored in the storage bag 100 may not be supplied with sufficient oxygen to the patient. When the pressure or the resistance is more than the threshold value within such a short time, the coupling part 145 implemented by a spring or the like can drop the emergency air inflow pipe 140 from the first communication part 110, And can be additionally supplied to the patient through the communication part 110.

Alternatively, the coupling portion 145 may be formed in the form of a one-way valve having an arbitrary opening resistance. In this case, the coupling portion 145 completely disengages the emergency air inflow pipe 140 from the first communication portion 110 But instead may operate in a manner that is open as needed.

In the above description, the storage bag 100 is made of a soft material, so that it can be easily expanded and contracted so as to stably supply oxygen at a high concentration even in a fast breathing of a patient.

2 is a view showing a case where a face oxygen mask according to an embodiment of the present invention is worn on a patient. The face oxygen mask 50 is mounted so that the rim 10 is attached to the face of the patient 5 and covers the face of the patient 5. [ At this time, the first communication part 110 is a path for supplying high-concentration oxygen from the storage bag 100 to the patient 5 at the time of inspiration of the patient. One end of the first communication part 110 is connected to the patient 5, Of the nose. On the contrary, the second communication part 120 is a path for discharging the air externally discharged by the patient at the time of patient's breath, and one end of the second communication part 120 may be positioned around the mouth of the patient.

Through this arrangement, the valve plate 150 is automatically moved according to the patient's expiration and intake, and the first communication part 110 and the second communication part 120 are opened and closed. 2, the valve 150 is included in the first communication part 110. However, the valve 150 may be provided in the first communication part 110 and the second communication part 120, And the respective communication portions are opened and closed. At this time, the valve plates disposed in the first communication part 110 and the second communication part 120 are fixed to maintain a constant angle with each other, and when one communication part is opened, the other communication part can be closed.

3 is a front view of a face oxygen mask according to another embodiment of the present invention. The embodiment shown in FIG. 3 is substantially similar to FIG. 1, but is different from FIG. 1 in that the sizes of the first communication portion 110 and the second communication portion 120 are different from each other.

That is, in the embodiment of FIG. 3, the second communicating part 120 is implemented with a relatively larger size (or width) than the first communicating part 110. Accordingly, the second plate films 154 and 158 in the second communication part 120 are formed to be larger than the first plate films 152 and 156 so that the second communication part 120 can be sufficiently closed.

The embodiment of FIG. 3 differs from FIG. 1 in that the operation of the first communication unit 110 is controlled by the control of the second communication unit 120. That is, since the second valve plate of the second communication portion 120 is larger than the first valve plate at the patient's expiration time, the second valve plate is preferentially moved to the position 154, and the first valve plate is automatically moved from the position 156 to the position 152 . That is, the valve plate in the first communication portion 110 is operated by the valve plate in the second communication portion 120. On the contrary, when the patient is sucked, the second valve plate automatically closes the second communication part 120 due to the difference in size between the second valve plate and the first valve plate, and the first valve plate moves to the first communication part The high-concentration oxygen can be introduced into the patient by opening the valve 110.

4 is a front view of a face oxygen mask according to another embodiment of the present invention. The embodiment of FIG. 4 is a modification of the embodiment described with reference to FIG. 3. In FIG. 4, the second communicating part 120 is implemented with a larger size (or width) than the first communicating part 110, similar. 4 shows a state in which one end of the first communication part 110 into which high-concentration oxygen flows from the storage bag 100 to the first communication part 110 and one end of the air communicated from the second communication part 120 And one side end portion discharged to the outside is positioned so as to face the same direction.

1 to 3, one end of the first communication part 110, which is connected to the storage bag 100, is directed to the lower side of the patient's face, and the other end of the second communication part 120 And one end of the air exhausted to the outside is directed to the opposite direction to the direction of the face of the patient. However, in the embodiment of Fig. 4, an embodiment is described in which both end portions of the two communicating portions are disposed so as to face the direction of the face of the patient. Also in this embodiment, since the valve plate in the second communication portion 120 and the second communication portion 120 is configured to be larger than the valve plate in the first communication portion 110 and the first communication portion 110, The first communicating part 110 is opened and closed by the operation of the valve plate in the valve body 120, similar to that described with reference to Fig.

5 to 9, a face oxygen mask structurally different from the embodiment described above with reference to FIGS. 1 to 4 will be described. FIG. 5 is a front view of a face oxygen mask according to another embodiment of the present invention, and FIG. 6 is a view showing when a face oxygen mask according to the embodiment of FIG. 5 is worn by a patient.

The face oxygen mask provided as an embodiment of the present invention includes a storage bag 100 into which a gas to be supplied to a patient is introduced and stored and a storage bag 100 connected to the storage bag 100, And a second communication part 300 in which the gas provided through the first communication part 200 is accommodated or the gas by the patient's expiration is accommodated.

5, the first communication part 200 is provided with an inlet port 210 through which high-concentration oxygen to be supplied to the patient is supplied from the outside, and high-concentration oxygen to be supplied to the patient is opened to be supplied to the second communication part 300 The first plate 220 may be included. The high concentration oxygen supplied to the patient is continuously supplied from the external oxygen supply device to the inlet 210 through the oxygen hose 400. [ The high concentration oxygen supplied through the inlet 210 may be stored in the storage bag 100 connected to the lower portion of the first communication unit 200.

The first valve 220 is disposed on the upper portion of the first communication portion 200 and the oxygen rich gas flows from the first communication portion 200 to the second communication portion 300 when the first valve 220 is opened Can be moved.

The second communication portion 300 is configured to cover the face portion including the nose and mouth of the patient so that high-concentration oxygen can be accommodated or gas by the patient's breath can be received. The second communication part 300 includes a second valve plate 310 which is opened to allow the gas generated by the patient's breath to be discharged to the outside.

The first valve 220 is connected to a first rod 230 having a predetermined length and the first rod 230 is disposed opposite to the inlet 210 to generate a first valve 230 based on the pressure of the high concentration oxygen flowing from the inlet 210. . The first valve 220 can be opened or closed by the movement of the first rod 230.

Meanwhile, the second plate 310 is connected to the second rod 320 having a predetermined length, and one end of the second rod 320 may be in contact with the top of the first plate 220. The upper portion of the first valve body 220 is pressed by the end of the second rod 320 connected to the second valve body 310 and the first valve body 220 is pressurized by the oxygen pressure continuously flowing from the inlet 210. [ The first plate 220 is pressed downward by pressing the distal end of the first rod 230 connected to the lower portion of the first plate 220. Therefore, the first valve body 220 is always closed when no external air pressure is applied, thereby solving the problem that the valve provided in the conventional face oxygen mask is opened and the air released by the patient again flows.

The end of the first rod 230 according to an embodiment of the present invention may be in the form of a bowl to collect all or a portion of the gas (e.g., oxygen) introduced from the inlet 210. Since the distal end of the first rod 230 is formed in a bowl shape and the distal end of the first rod 230 receives the pressure of the gas (for example, oxygen) introduced from the inlet 210 more strongly, Is subjected to a stronger force to the lower part, and the opening of the first valve 220 becomes more difficult than the conventional face oxygen mask. Therefore, the oxygen flowing into the first fluid communication part 200 through the inlet 210 can be stored in the storage bag 100 without being discharged out of the first valve 220.

7 and 8 are diagrams showing the operation of the face oxygen mask according to the embodiment described above with reference to FIGS. 5 and 6. FIG. 7 shows the operation of the patient during inspiration, FIG. Respectively.

7 and 8, the first plate 220 and the second plate 310 are alternatively opened. Interchangeable opening may be referred to as exclusive opening or the like and the second valve 310 is closed while the first valve 220 is opened and the second valve 310 is closed while the first valve 220 is closed, Lt; RTI ID = 0.0 > 310 < / RTI >

As shown in FIG. 7, during the inspiration of the patient, the second valve plate 310 is closed and the first valve plate 220 is opened, so that the high concentration Oxygen is transferred to the respiratory tract of the patient through the first fluid communication portion 200. On the other hand, the second plate film 310 can be closed by being hooked on the second plate fixing table 311.

That is, the pressure of the gas generated when the patient is inhaled is a sum of the pressure applied to the first valve 220 by the end of the second rod 320 and the pressure applied to the end of the first rod 230 The first valve 220 can be opened during the inspiration of the patient.

8, during the exhalation of the patient, the first valve 220 is closed, and as the second valve 310 is opened, the patient's exhalation gas flows out of the face oxygen mask . The first fluid communication part 200 and the storage bag 100 are connected to the inflow port 210 through the first fluid communication part 200 because the first valve 220 is closed, And is filled with high-concentration oxygen supplied through the pipe. On the other hand, the first plate 220 can be closed by being fixed to the first plate fixing table 221.

The pressure of the gas generated when the patient is breathing opens the second plate 310 and the second rod 320 connected to the second plate 310 can move as the second plate 310 is opened. That is, the upper portion of the first valve 220, which is in contact with the end of the second rod 320 due to the movement of the second rod 320, may be further pressurized to close the first valve 220. That is, the first plate 220 is closed due to the movement of the second plate 310 and the second rod 320.

FIG. 9 is a diagram specifically showing a valve according to an embodiment of the present invention.

The hypotenuse of the first valve 220 and the bottom of the first communication part 200 may be formed to be inclined at a predetermined angle? According to an embodiment of the present invention. In other words, the first plate 220 may have a shape that is inclined at a predetermined angle? Rather than a structure that is perpendicular to the first communicating part 200. This is because the first valve body 220 and the second valve body 310 can be more easily opened alternately by intake or exhaust.
