Description

Technical Field

[0001] The invention relates to the technical field of breathing masks, in particular to a floating anti-falling breathing mask. Background Art

[0002] In respiratory care, respiratory masks can provide patients with oxygen supply, non-invasive ventilation or other forms of respiratory support. They are widely used, especially in the treatment of respiratory diseases such as chronic obstructive pulmonary disease, asthma, pneumonia, etc., in which respiratory masks play a vital role.

[0003] However, in actual applications, we found that traditional respiratory masks also have some problems. For example, when worn for a long time, the respiratory mask is prone to position displacement or even fall off due to changes in patient posture, tube traction, nursing operations, etc. This displacement not only affects the sealing of the respiratory mask, but also puts pressure on the patient's facial muscles and causes discomfort.

[0004] In order to enhance the stability of the respiratory mask, in the prior art, many respiratory masks are designed with a "forehead pad". The respiratory mask covers the mouth and nose, and the forehead pad rests on the forehead, and both are fixed by straps. This can significantly improve the stability of the respiratory mask when worn and reduce the risk of falling off.

[0005] However, in actual operation, we found that although the forehead pad improves the stability of wearing the respiratory mask, it cannot completely solve the problem of easy displacement of the respiratory mask. If the displacement is small, the respiratory mask can still function normally. If the displacement is large, the respiratory mask will lose its sealing and even fall off.

[0006] Therefore, there is an urgent need for an improved respiratory mask that can effectively prevent displacement and falling off during long-term wearing. Summary of the invention

[0034] 2. For this floating anti-falling breathing mask, when the electromagnet is activated, the gas automatically enters the plug cavity, pushing the entire mask body to float slightly, and then the mask body will slowly drop under the action of the supporting spring and gravity. This can effectively reduce the long-term pressure of the mask body on the patient's facial muscles, significantly improve the wearing comfort, and is especially suitable for patients who wear it for a long time.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Embodiment 1:

[0047] See also Figure 1-Figure 4A floating anti-falling breathing mask comprises a mask body 1, such as Figure 1 As shown, face straps 2 are provided on both sides of the mask body 1, and the top is connected to the forehead pad 3 through a connector. Head straps 4 are provided on both sides of the forehead pad 3. When in use, the mask body 1 covers the mouth and nose, and the forehead pad 3 rests on the forehead. The two are fixed by the face straps 2 and the head straps 4 respectively. The design of the forehead pad 3 can significantly improve the wearing stability of the mask body 1.

[0048] In this embodiment, the connector includes a floating cylinder 6 and a movable plate 9 movably disposed in the floating cylinder 6. The bottom of the movable plate 9 is connected to the mask body 1 through a connecting rod 5, and the top of the floating cylinder 6 is connected to the forehead pad 3 through an insertion rod 7.

[0049] like Figure 2 As shown, an upper spring 10 is provided between the top of the moving plate 9 and the inner top wall of the floating cylinder 6, a lower spring 11 is provided between the bottom of the moving plate 9 and the inner bottom wall of the floating cylinder 6, an upper electromagnet 16 is fixedly mounted on the inner top wall of the floating cylinder 6, and a lower electromagnet 17 is fixedly mounted on the inner bottom wall of the floating cylinder 6. When the upper electromagnet 16 is energized, the moving plate 9 can be attracted to move upward by magnetic force, and when the lower electromagnet 17 is energized, the moving plate 9 can be attracted to move downward by magnetic force;

[0050] In the present invention, further, as Figure 3 As shown, two upper mounting grooves 12 are relatively formed on the inner wall of the upper part of the floating cylinder 6, and an upper opposing photoelectric sensor group 13 is fixedly installed in the upper mounting grooves 12. Two lower mounting grooves 14 are relatively formed on the inner wall of the lower part of the floating cylinder 6, and a lower opposing photoelectric sensor group 15 is fixedly installed in the lower mounting grooves 14. The output ends of the upper opposing photoelectric sensor group 13 and the lower opposing photoelectric sensor group 15 are electrically connected to the controller, and the output end of the controller is electrically connected to the input ends of the upper electromagnet 16 and the lower electromagnet 17.

[0051] When the mask body 1 moves downward due to an external force, the connecting rod 5 will also pull the movable plate 9 downward. The movable plate 9 will compress the lower spring 11 while blocking the lower opposed-beam photoelectric sensor group 15. The lower opposed-beam photoelectric sensor group 15 is blocked and transmits the signal to the controller. The controller controls the upper electromagnet 16 to be energized. The upper electromagnet 16 can attract the movable plate 9 to move upward, and then pull the mask body 1 upward through the connecting rod 5 to overcome the downward external force of the mask body 1.

[0052] Similarly, when the mask body 1 moves upward due to external force, the connecting rod 5 will also push the movable plate 9 to move upward. The movable plate 9 will block the upper photoelectric sensor group 13 while compressing the upper spring 10. The upper photoelectric sensor group 13 is blocked and transmits the signal to the controller. The controller controls the lower electromagnet 17 to be energized. The lower electromagnet 17 can attract the movable plate 9 to move downward, and then push the mask body 1 downward through the connecting rod 5 to overcome the upward external force of the mask body 1.

[0053] Thus, in this embodiment, when the mask body 1 has a tendency to move downward or upward, the two electromagnets can generate forces in opposite directions, so that the mask body 1 is kept in a stable position, effectively preventing the mask body 1 from shifting or falling off due to changes in the patient's body position, pipeline traction or nursing operations, ensuring the stability of the mask body 1, and achieving the effect of preventing shifting and falling off;

[0054] The above-mentioned "upward movement" and "downward movement" also include the downward displacement or upward position of the mask body 1, which can trigger the floating device as long as the movable plate 9 is driven to move.

[0055] Specifically in the application, the controller will immediately cut off the power after the upper electromagnet 16 or the lower electromagnet 17 is energized, so that the movable plate 9 can return to its original position under the elastic force of the upper spring 10 and the lower spring 11, thereby maintaining the correct position of the mask body 1;

[0056] The specific circuit structure can be constructed by those skilled in the art according to actual needs.

[0057] like Figure 4 As shown, a through slot 18 is also provided on the connecting rod 5 to allow the laser of the lower opposing photoelectric sensor group 15 to pass through.

[0058] Embodiment 2:

[0059] See also Figure 5 and Figure 6 , based on the first embodiment, in this embodiment, as Figure 5 As shown, a plug cavity 20 is provided inside the forehead pad 3 in the same direction as the insertion rod 7, a piston 19 is movably provided in the plug cavity 20, the insertion rod 7 is fixedly mounted on the piston 19, and a support spring 21 is also sleeved on the insertion rod 7, and the support spring 21 is fixedly arranged between the piston 19 and the inner wall of the plug cavity 20;

[0060] For easier understanding, please refer to Figure 6 A schematic diagram (not a structural diagram) is shown as Figure 6As shown, one side of the upper part of the floating cylinder 6 is connected with an upper air inlet pipe 22, on which an upper one-way air inlet valve 23 is provided, the other side of the upper part of the floating cylinder 6 is connected with the plug cavity 20 through an upper air outlet pipe 24, on which an upper one-way air outlet valve 25 is provided, one side of the lower part of the floating cylinder 6 is connected with a lower air inlet pipe 26, on which a lower one-way air inlet valve 27 is provided, the other side of the lower part of the floating cylinder 6 is connected with the plug cavity 20 through a lower air outlet pipe 28, on which a lower one-way air outlet valve 29 is provided, and in addition, a micro exhaust channel 30 is opened at the bottom of the plug cavity 20;

[0061] When the upper electromagnet 16 is energized to attract the moving plate 9 to move upward, the moving plate 9 will also squeeze the air in the upper half of the floating cylinder 6 into the plug cavity 20 through the upper air outlet pipe 24;

[0062] When the lower electromagnet 17 is energized to attract the moving plate 9 to move downward, the moving plate 9 will also squeeze the air in the lower half of the floating cylinder 6 into the plug cavity 20 through the lower air outlet pipe 28;

[0063] A large amount of space instantly enters the plug cavity 20, which pushes the piston 19 upward, and then pushes the entire mask body 1 to float upward through the insertion rod 7; then, through the exhaust of the micro-exhaust channel 30, the gravity of the mask body 1 itself, and the restoring force of the support spring 21, the piston 19 will move down again to return to its original position, thereby allowing the mask body 1 to tightly cover the patient's mouth and nose again;

[0064] This design can effectively reduce the long-term pressure of the mask body 1 on the patient's facial muscles, significantly improve the wearing comfort, and is particularly suitable for patients who wear the mask for a long time. It also solves the problem that the mask body 1 is easily squeezed by moving directly on the patient's face. The position of the mask body 1 is easily adjusted by briefly floating upward the mask body 1.

[0065] Embodiment three:

[0066] See also Figure 7 and Figure 8 On the basis of the first or second embodiment, in this embodiment, a rod groove 8 is provided at the top of the floating cylinder 6, and the insertion rod 7 is movably inserted in the rod groove 8;

[0067] like Figure 8 As shown, the insertion rod 7 is evenly provided with a card slot 31, and a card column 32 is movably provided in the card slot 31. The card column 32 is fixedly mounted on a pressure plate 33. The pressure plate 33 is movably arranged in a plate cavity 34 provided inside the top of the floating cylinder 6, and is supported by a lower support spring 35. In this way, the floating cylinder 6 can be positioned on the insertion rod 7 by inserting the card column 32 into the card slot 31, so as to facilitate the adjustment of the position of the floating cylinder 6 and the mask body 1. When adjusting, the floating cylinder 6 can be directly pushed on the insertion rod 7.

[0068] However, this does not completely lock the position of the floating cylinder 6, and the floating cylinder 6 can still move on the insertion rod 7 due to external force. Figure 8 As shown, a nut 36 is also provided at the top of the floating cylinder 6, and a screw rod 37 is threadedly connected to the inner wall of the nut 36. One end of the screw rod 37 passes through the plate cavity 34, and the other end extends to the outside of the floating cylinder 6 and is fixedly connected to a knob 38;

[0069] Therefore, by turning the knob 38 and making the end of the screw rod 37 abut against the pressure plate 33 , the upward movement of the pressure plate 33 can be limited, thereby limiting the separation of the clamping column 32 from the clamping groove 31 and locking the position of the floating cylinder 6 .

[0070] In this embodiment, the locking structure of the insertion rod 7 makes the adjustment of the mask body 1 more flexible. When wearing, the position of the mask body 1 can be quickly adjusted to ensure comfortable wearing. After wearing, the position of the mask body 1 can be freely locked to ensure stable positioning.

[0071] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
