Description

Technical Field

[0001] The invention relates to the technical field of oxygen inhalation masks, and in particular to oxygen inhalation equipment for cardiovascular and cerebrovascular treatment and care. Background Art

[0002] For patients with many diseases, supplementary oxygen inhalation is an important treatment measure. Supplementary oxygen inhalation is usually completed with the help of oxygen inhalation equipment. The mask in the oxygen inhalation equipment is in direct contact with the patient. The mask will exert pressure on the patient's skin during wearing. When the patient wears it for a long time, this pressure will cause the patient to experience various discomfort symptoms, such as skin redness and pain, and may even cause skin damage, seriously affecting the patient's comfort. In addition, the mask needs an air outlet to discharge the patient's exhaled gas, but in order to prevent oxygen from being lost from these holes, an air outlet valve is usually set. The patient's exhaled gas needs to overcome a certain pressure resistance when passing through the air outlet valve, which makes it difficult for the exhaled gas to be discharged smoothly. When the patient's breathing frequency is fast or the breathing force is strong, this discomfort will be more obvious, which may cause the patient to feel shortness of breath, increase the patient's pain, and is not conducive to the patient's physical recovery.

[0021] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0022] like Figures 1 to 7 As shown, an embodiment of the present invention provides a cardiovascular and cerebrovascular treatment and care oxygen inhalation device, which includes a mask 110, a contact sleeve 130, a support bar 140 and an adjustment component.

[0023] The mask 110 is provided with two ear straps, and an elastic cord is provided between the two ear straps, and the elastic cord can be worn on the wearer's head. The mask 110 is provided with an oxygen supply tube 120, and the oxygen supply tube 120 is used to provide oxygen to the inside of the mask 110.

[0024] The contact sleeve 130 is arranged at the edge of the mask 110. The contact sleeve 130 is made of a flexible material, for example, the contact sleeve 130 is made of rubber, and the contact sleeve 130 can fully contact the wearer's face. The contact sleeve 130 is hollow inside, and has a first side wall that contacts the skin and a second side wall that connects to the mask 110. Furthermore, the first side wall and the second side wall are both arc side walls, and the cross-sectional profile of the contact sleeve 130 is slightly quasi-circular. When the contact sleeve 130 is transversely cut, the internal profile of the contact sleeve 130 is slightly quasi-circular.

[0025] The support bar 140 is a plate-like structure. The support bar 140 is a metal thin plate. The support bar 140 can be deformed. The support bar 140 can be inserted into the contact sleeve 130. The width of the support bar 140 is greater than the diameter of the inside of the contact sleeve 130. When the support bar 140 is installed in the contact sleeve 130, the support bar 140 is deformed into an arc. The support bar 140 has a third side wall and a fourth side wall with relatively small areas. The third side wall and the fourth side wall of the support bar 140 are located on two opposite side walls of the support bar 140. When the support bar 140 is arranged inside the contact sleeve 130, the third side wall of the support bar 140 abuts against the inner side wall corresponding to the first side wall of the contact sleeve 130, and the fourth side wall of the support bar 140 abuts against the inner side wall corresponding to the second side wall of the contact sleeve 130. Since the support bar 140 is arc-shaped inside the contact sleeve 130, the support bar 140 has a tendency to reset. The reset force of the support bar 140 squeezes the inner side walls corresponding to the first side wall and the second side wall of the contact sleeve 130, so that the contact sleeve 130 has a tendency to deform into an elliptical shape. The support bar 140 can be deformed in the contact sleeve 130 and can change the contact position with the inner wall of the contact sleeve 130. When the contact position between the support bar 140 and the inner wall of the contact sleeve 130 changes, the end point position of the ellipse formed by the contact sleeve 130 changes.

[0026] The adjustment component includes a first adjustment unit and a second adjustment unit. The first adjustment unit is used to adjust the contact position between the support bar 140 and the inner wall of the contact sleeve 130 when the contact sleeve 130 contacts the wearer's skin. Specifically, when the wearer wears the mask 110 on the face, the first adjustment unit adjusts the contact position between the support bar 140 and the inner wall of the contact sleeve 130. After the contact position between the support bar 140 and the inner wall of the contact sleeve 130 is adjusted, the degree of squeezing of the inner wall corresponding to the first side wall of the contact sleeve 130 by the support bar 140 changes, and the difficulty of deformation of the first side wall of the contact sleeve 130 is reduced. If the first side wall of the contact sleeve 130 causes squeezing wrinkles on the wearer's face, the support bar 140 is adjusted by the first adjustment unit to reduce the probability of squeezing wrinkles on the wearer's face. The second adjustment member is used to change the contact position between the support bar 140 in the local area and the inner wall of the contact sleeve 130 when the wearer exhales. When the contact position between the support bar 140 in the local area and the inner wall of the contact sleeve 130 changes, the difficulty of deformation of the local area of ​​the first side wall of the contact sleeve 130 is reduced, and the gas exhaled by the wearer can be discharged from the mask 110 in this area, so that the exhaled gas can be discharged smoothly.

[0027] The present invention provides a cardiovascular and cerebrovascular treatment and care oxygen inhalation device, in which a contact sleeve 130 made of a flexible material is arranged on the edge of a mask 110, so that the position contacting the wearer's face is the flexible contact sleeve 130, thereby reducing the patient's discomfort. At the same time, a support bar 140 is arranged inside the contact sleeve 130, and the support bar 140 supports the contour of the contact sleeve 130. In an initial state, the third side wall of the support bar 140 abuts against the inner side wall corresponding to the first side wall of the contact sleeve 130, and the fourth side wall of the support bar 140 abuts against the inner side wall corresponding to the second side wall of the contact sleeve 130, wherein the wearer's face contacts the first side wall of the contact sleeve 130, and the support bar 140 can provide a certain pressure to the inner side wall corresponding to the first side wall of the contact sleeve 130; when the wearer wears the mask 110 on the face, the first adjustment unit in the adjustment component adjusts the contact position between the support bar 140 and the inner side wall of the contact sleeve 130, and adjusts the contact position between the support bar 140 and the contact sleeve 130. After the contact position of the inner wall of the contact sleeve 130 is adjusted, the degree of compression of the inner wall corresponding to the first side wall of the contact sleeve 130 by the support bar 140 changes, and the difficulty of the first side wall of the contact sleeve 130 to deform is reduced. If the first side wall of the contact sleeve 130 causes compression wrinkles on the wearer's face, the support bar 140 is adjusted by the first adjustment unit to reduce the probability of compression wrinkles on the wearer's face; further, by providing a second adjustment unit, the contact position of the support bar 140 and the inner wall of the contact sleeve 130 in a local area is changed when the wearer exhales. When the contact position of the support bar 140 and the inner wall of the contact sleeve 130 in a local area changes, the difficulty of the local area of ​​the first side wall of the contact sleeve 130 to deform is reduced, and the gas exhaled by the wearer can be discharged from the mask 110 in this area, so that the exhaled gas can be discharged smoothly, reducing the discomfort of the wearer when wearing the mask 110.

[0028] In one embodiment, the first adjustment unit includes an adjustment block 150 and a clamping member. The contact sleeve 130 is arranged along the edge contour of the mask 110. A slide rail 260 is arranged on the contact sleeve 130. The slide rail 260 is arranged along the extension direction of the contact sleeve 130. The slide rail 260 connects the inside of the contact sleeve 130 with the external environment. The adjustment block 150 is slidably arranged along the slide rail 260. In the initial state, the adjustment block 150 is arranged at the end of the slide rail 260. The clamping member is arranged on the adjustment block 150, and the clamping member is always inside the contact sleeve 130. The support bar 140 can form a raised area inside the contact sleeve 130. After the support bar 140 forms the raised area inside the contact sleeve 130, the contact position between the support bar 140 at the raised area and the inner wall of the contact sleeve 130 changes. The clamping member can clamp the raised area of ​​the support bar 140. When the adjustment block 150 slides along the guide rail, the adjustment block 150 drives the clamping member to slide along the guide rail synchronously. The raised area clamped by the clamping member can change position along the extension direction of the support bar 140. Specifically, the raised area is composed of a section of the support bar 140. When the adjustment block 150 slides along the slide rail 260, the support bar 140 forming the raised area is continuously switched, so that the raised area changes position along the extension direction of the support bar 140. After the adjustment block 150 slides along the slide rail 260, any position of the support bar 140 inside the contact sleeve 130 changes position once. When the position of the support bar 140 changes inside the contact sleeve 130, the support bar 140 deforms. After the support bar 140 deforms, the support bar 140 is actively reset inside the contact sleeve 130. When the contact sleeve 130 contacts the wearer's skin, the adjustment block 150 is driven to slide on the slide rail 260.

[0029] In one embodiment, the clamping member includes a first gear rod 160, a second gear rod 170, a first clamping rod 180 and a second clamping rod 190. The first gear rod 160 and the second gear rod 170 are fixedly connected to the adjustment block 150. There is a first preset angle between the first gear rod 160 and the second gear rod 170. The first gear rod 160 and the second gear rod 170 are always inside the contact sleeve 130. The ends of the first gear rod 160 and the second gear rod 170 abut against the surface of the support bar 140 at the same time. When the adjustment block 150 slides on the slide rail 260, the first gear rod 160 and the second gear rod 170 can slide on the surface of the support bar 140. The first clamping rod 180 and the second clamping rod 190 are hinged to the adjustment block 150 at the same time. Furthermore, the first clamping rod 180 and the second clamping rod 190 are hinged to each other. In the initial state, the first clamping rod 180 and the second clamping rod 190 do not contact the surface of the support bar 140. When the raised area is formed on the support bar 140, the first gear rod 160 and the second gear rod 170 prevent the raised area from moving inside the contact sleeve 130. The first clamping rod 180 and the second clamping rod 190 When a raised area is formed on the support bar 140, it can rotate to abut the surface of the support bar 140. When a raised area is formed on the support bar 140, the first clamping rod 180 and the second clamping rod 190 can cooperate with the first gear rod 160 and the second gear rod 170 to stabilize the shape of the raised area. Subsequently, the adjustment block 150 is driven to slide on the slide rail 260, and the adjustment block 150 drives the first gear rod 160, the second gear rod 170, the first clamping rod 180 and the second clamping rod 190 to move synchronously.

[0030] In one embodiment, the contact sleeve 130 is provided with a first opening and a second opening. Specifically, the contact sleeve 130 has a cut-off area on the mask 110, and the cut-off area is provided below the mask 110, and the cut-off area corresponds to the chin area of ​​the wearer. The cut-off area is provided so that the contact sleeve 130 forms the first opening and the second opening. The length of the support bar 140 is greater than the length of the contact sleeve 130, so that there are redundant support bars 140 outside the contact sleeve 130. When the contact sleeve 130 contacts the wearer's skin, the support bars 140 outside the contact sleeve 130 are transported into the contact sleeve 130 through the first opening or the second opening, so that the support bars 140 form a convex area inside the contact sleeve 130. Further, when there are support bars 140 inside the contact sleeve 130, the support bars 140 outside the contact sleeve 130 are transported into the contact sleeve 130, and the support bars 140 are accumulated inside the contact sleeve 130, so that a convex area of ​​the support bars 140 is formed inside the contact sleeve 130.

[0031] In one embodiment, a limit block 210 is provided at the end of the support bar 140, and the limit block 210 is used to prevent the end of the support bar 140 from entering the interior of the contact sleeve 130. Further, the diameter of the limit block 210 is larger than the diameter of the first opening or the second opening, and when the raised area is prepared inside the contact sleeve 130, the end of the support bar 140 is prevented from completely entering the interior of the contact sleeve 130.

[0032] In one embodiment, the second adjustment component includes a detection member and a toggle member, the detection member is used to detect the wearer's breathing, and the toggle member is used to toggle the support bar 140 in a local area of ​​the contact sleeve 130 when the wearer exhales. For example, the detection member is a carbon dioxide detector, and when the wearer exhales, the carbon dioxide exhaled by the wearer can be detected by the carbon dioxide detector in time. The mask 110 is provided with a control panel, and the control panel can receive the detection signal of the carbon dioxide detector. The control panel can control the toggle member. When the carbon dioxide detector detects the wearer's exhalation, the control panel promptly controls the toggle member to toggle the support bar 140 in the local area of ​​the contact sleeve 130. After the support bar 140 in the local area of ​​the contact sleeve 130 is deformed, the contact position between the support bar 140 in the local area and the inner side wall of the contact sleeve 130 is changed, and the difficulty of deformation of the local area of ​​the first side wall of the contact sleeve 130 is reduced, and the gas exhaled by the wearer can be discharged from the mask 110 in this area, so that the exhaled gas can be discharged smoothly.

[0033] In one embodiment, the toggle member includes a toggle plate 220, which is rotatably connected to the inner side wall of the contact sleeve 130, and the toggle plate 220 overlaps the edge of the third side wall of the support bar 140. When the wearer exhales, the toggle plate 220 rotates, and the toggle plate 220 can push the support bar 140. Specifically, when the toggle plate 220 pushes the support bar 140, the third side wall of the support bar 140 changes the position of abutting against the inner side wall of the contact sleeve 130, and the end point position of the ellipse formed by the contact sleeve 130 changes. At the same time, the difficulty of deformation of a local area of ​​the first side wall of the contact sleeve 130 is reduced.

[0034] In one embodiment, the detection member includes a fitting plate 230 and a rotating shaft 240. The rotating shaft 240 is rotatably connected to the mask 110. The rotating shaft 240 is disposed at the cut-off area of ​​the contact sleeve 130 on the mask 110. One end of the rotating shaft 240 extends to the inside of the contact sleeve 130. The rotating shaft 240 is fixedly connected to the toggle plate 220. The rotation of the rotating shaft 240 can drive the toggle plate 220 to rotate synchronously. The fitting plate 230 is fixedly connected to the rotating shaft 240. The fitting plate 230 always fits the chin of the wearer. When the wearer exhales, the fitting plate 230 can drive the rotating shaft 240 to rotate. Further, when the wearer exhales, the wearer's chin will fluctuate up and down. Since the fitting plate 230 always fits the wearer's chin, when the wearer's chin fluctuates up and down, the fitting plate 230 drives the rotating shaft 240 to rotate.

[0035] In one embodiment, the detection member further includes a first elastic member, which is disposed between the fitting plate 230 and the mask 110. Specifically, the first elastic member is a first spring 250, which is in an original length state in an initial state, and when the mask 110 is worn on the wearer's face, the first spring 250 is compressed, and the fitting plate 230 is closely fitted on the wearer's chin.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
