Description

Technical Field

[0001] The present invention relates to the technical field of ventilator masks, and more specifically, to a ventilator mask with a pressure ulcer prevention function. Background Art

[0002] In the modern medical field, as an important life support device, ventilators are widely used in the treatment of various patients who need assisted breathing. For some patients, wearing a ventilator mask for a long time has become a necessary means to maintain stable vital signs. However, in the design and use of existing ventilator masks, some problems that need to be solved urgently have emerged, among which the problem of facial skin pressure ulcers is particularly prominent;

[0003] When wearing a ventilator mask for a long time, the area of the patient's face in contact with the mask bears pressure for a long time. Especially on both sides of the nose, due to its unique facial anatomical structure, it is in a relatively prominent position when the mask is worn, resulting in more concentrated pressure on this part. As the wearing time continues to extend, the mask continuously contacts the same position on the face, and the pressure continuously acts on the skin on both sides of the nose, leading to serious obstruction of local blood circulation;

[0004] The human skin relies on normal blood circulation to provide nutrients and oxygen and carry away metabolic wastes. When local blood circulation is blocked due to long-term pressure, skin cells cannot obtain sufficient nutrient supply, and metabolic wastes cannot be discharged in time, thus leading to disorders of cell metabolic functions. In the initial stage, this disorder is manifested as skin redness and swelling, which is a stress response of the body to local ischemia and hypoxia;

[0005] At the same time, during the patient's use of the ventilator, although there may be slight head movement, due to the tight fit between the mask and the face, its long-term fit at the same position on the face causes continuous friction between the skin on both sides of the nose and the mask. This friction will continuously wear the cutin layer of the skin and weaken the barrier function of the skin. And the exhaled gas accumulates inside the mask, increasing the humidity in the contact area. The skin is in a humid environment for a long time, further reducing the skin's tolerance to pressure and friction;

[0006] Over time, if the above situation is not effectively improved, the skin redness and damage will continue to deteriorate, and the skin tissue will gradually lose its normal physiological functions, and finally develop into pressure ulcers. Pressure ulcers not only bring great pain to patients, affect their quality of life, but also increase the risk of infection, prolong the patient's recovery period, and even may cause serious complications, posing a threat to the patient's life and health. Summary of the Invention

[0020] The technical solution provided by the present invention has at least the following beneficial effects compared with the prior art:

[0021] In the above solution, when the present mask is actually used, it is firmly fixed on the patient's face by means of an elastic strap, and at the same time, it is connected to a ventilator by using a threaded joint at the end of the ventilation hose on the connecting head. When it is necessary to adjust the mask, the electric push rod is started to push the bracket and the adjusting wheel to rotate, and then the mask body is pulled. Since the mask body is made of a highly elastic material, it can be flexibly adjusted according to actual needs. For example, at different times of the day, in the morning, the electric push rod is started to expand the bracket, and the mask body opens; at noon and at night, by controlling the electric push rod to contract, the bracket and the mask body gradually contract. This way of adjusting the opening degree and area of the mask body according to time can effectively prevent it from pressing the same position of the patient's face for a long time, effectively reducing the possibility of pressure sores and providing a more comfortable use experience for the patient.

[0022] The connection mechanism is arranged such that when it is necessary to clean or replace the mask body, only need to pull the pull plate, the pull plate drives the coupling shaft, so that the limit block compresses the limit spring to contract, the limit block disengages from the limit groove, and the clamping block can be pulled out from the inside of the clamping frame. Then separate the hook and the pull ring at the top of the mask body to complete the removal. The installation process is vice versa. Pull the pull plate to make the limit block disengage from the inside of the clamping frame, insert the clamping block and then release the pull plate. The limit spring resets and pushes the limit block to engage with the limit groove, and then hook the hook and the pull ring to complete the installation. Such a design makes the mask body easy to disassemble and assemble, provides convenience for subsequent daily maintenance and disinfection, and helps to maintain the hygiene and safety of the mask.

[0023] By setting the elastic component and the tightening mechanism to cooperate, during the application of this mask, the telescopic spring between the bottom plate and the substrate can play an auxiliary buffering role, and with the guidance of the support rod for the telescopic process, the overall device has good elasticity, effectively improving the comfort when wearing the mask body. And the movable mechanism further improves the practicality of the mask. When in use, start the driving motor, through the transmission of the gear and the toothed ring, drive the slider to slide in the annular groove, flexibly adjust the rotation of the bracket, and cause the mask body to deform, better adapting to the faces of different patients. In addition, twisting the adjustment handle can drive the screw rod in the rail frame to rotate, drive the movable plate to slide up and down, and make the hook rise and fall accordingly. When the mask body expands or contracts, further optimize its shape and strengthen the anti-pressure ulcer effect, comprehensively improving the patient's use experience.

[0054] As Figures 1 to 10 shown, an embodiment of the present invention provides a ventilator mask with a pressure ulcer prevention function, including a mask body 1. The mask body 1 is made of a highly elastic rubber material. Elastic straps 2 are fixedly installed on both sides of the mask body 1. A connection seat 3 is fixedly installed in the middle of the top of the mask body 1. A connection head 4 is fixedly connected to the top of the connection seat 3. An air ventilation hose 5 is fixedly installed on the outer side of the connection head 4. The input end of the air ventilation hose 5 is communicated with the inside of the mask body 1. An adjustment device 6 is installed on the top of the mask body 1.

[0055] The adjustment device 6 includes a connection mechanism 61 and a ring body 62. An angle adjustment mechanism 63 is fixedly installed on the top of the connection mechanism 61. A movable mechanism 64 is installed on the outer side of the ring body 62 in an equidistant annular arrangement. The outer side of the movable mechanism 64 is connected to the adjustment mechanism. A tightening mechanism 65 is fixedly installed on the top of the ring body 62. The mask body 1 of the device made of a highly elastic rubber material can be stably worn on the patient's face through the elastic straps 2 on both sides. The connection head 4 on the top connection seat 3 is connected to the air ventilation hose 5, and the input end of the air ventilation hose 5 is communicated with the inside of the mask body 1 to realize the gas delivery to the ventilator. In the adjustment device 6, the connection mechanism 61 serves as a basic connection component to provide support for the angle adjustment mechanism 63. The angle adjustment mechanism 63 can change the angle of the mask body 1 to adapt to the facial contours of different patients. The movable mechanism 64 arranged annularly on the outer side of the ring body 62 can flexibly change its own position under the action of the adjustment mechanism, and then drive the connected adjustment mechanism to realize the shape adjustment of the mask body 1. At the same time, the tightening mechanism 65 on the top of the ring body 62 can finely adjust the tightness of the entire adjustment device 6 to ensure that the mask fits the face during use and will not cause pressure ulcers due to being too tight. At the same time, its contraction and expansion design can avoid the mask body 1 covering the same position of the patient's face for a long time at the edge, realizing a good pressure ulcer prevention function and wearing comfort.

[0056] As Figures 5 to 8 and Figure 10As shown in the figure, the movable mechanism 64 includes an annular groove 641 which is formed on the outer side of the ring body 62. The inner part of the annular groove 641 is slidably connected with sliders 642 arranged annularly at equal intervals. The outer side of the slider 642 is connected to the inner side of the angle adjustment mechanism 63. The top of the slider 642 is fixedly connected with a driving component 23 which is arranged on the top of the ring body 62. The driving component 23 includes a side arm 231 and a toothed ring 233. The side arm 231 is fixedly connected to the top of the slider 642, and the toothed ring 233 is fixedly installed on the top of the ring body 62. The top of the side arm 231 is fixedly connected with a driving motor 234, and the output end of the driving motor 234 penetrates through the side arm 231 and is fixedly connected with a gear 232. The gear 232 is meshed with the toothed ring 233. The annular groove 641 formed on the outer side of the ring body 62 provides a track for the movement of the whole mechanism. A plurality of sliders 642 are arranged annularly at equal intervals and slide in the annular groove 641. The outer side of the slider 642 is connected to the inner side of the angle adjustment mechanism 63, which can drive the angle adjustment mechanism 63 to move. The driving component 23 connected to the top of the slider 642 is the power source of the movable mechanism 64. The side arm 231 in the driving component 23 is fixed to the top of the slider 642, and the toothed ring 233 is installed on the top of the ring body 62. After the driving motor 234 at the top of the side arm 231 is started, its output end drives the gear 232 to rotate. Since the gear 232 is meshed with the toothed ring 233, the power generated by the driving motor 234 is transmitted through the gear 232 and the toothed ring 233, so that the slider 642 slides in the annular groove 641, and then drives the connected angle adjustment mechanism 63 to move, and then the deformation of the mask body 1 at the bottom can be flexibly adjusted, and the mask body 1 can be better adjusted.

[0057] As Figures 5 to 8 shown in the figure, the angle adjustment mechanism 63 includes a fixed block 631 which is fixedly installed on the outer side of the slider 642. The outer side of the fixed block 631 is hinged with a first hinge seat 632, and the bottom of the fixed block 631 is fixedly connected with a second hinge seat 633. The inner side of the first hinge seat 632 is rotatably connected with an adjustment wheel 634. The outer side of the adjustment wheel 634 is fixedly connected with a bracket 635. The outer end of the bracket 635 is fixedly installed with an elastic component 22. The outer end of the elastic component 22 is connected to the top of the connection mechanism 61. The bottom of the second hinge seat 633 is hinged with an electric push rod 637. The output end of the electric push rod 637 is provided with a hinge piece 638, and the electric push rod 637 is hinged with the upper inner side of the bracket 635 through the hinge piece 638 at its output end.

[0058] The elastic component 22 includes a base plate 221 which is fixedly installed at the outer end of the bracket 635. A telescopic spring 222 is fixedly installed at the bottom of the base plate 221. A bottom plate 223 is fixedly installed at the bottom of the telescopic spring 222. The bottom of the bottom plate 223 is connected to the connecting mechanism 61. Fixed rods 224 are fixedly installed at both ends of the top of the bottom plate 223. The top of the fixed rod 224 penetrates through the base plate 221, and the upper end of the fixed rod 224 is slidably connected to the base plate 221. The fixed block 631 on the outside of the slider 642 serves as a connection pivot. The first hinge seat 632 hinged on its outside and the second hinge seat 633 fixed at the bottom respectively provide connection points for the adjusting wheel 634 and the electric push rod 637. When the electric push rod 637 is started, the hinge member 638 at its output end pushes the bracket 635 to move. Since the adjusting wheel 634 is rotatably connected to the first hinge seat 632, it can assist the bracket 635 to smoothly change the angle. At the same time, the elastic component 22 fixed at the outer end of the bracket 635 plays a buffering and supporting role during the adjustment process. In the elastic component 22, the base plate 221 is installed at the outer end of the bracket 635, and the telescopic spring 222 at its bottom is connected to the bottom plate 223 to provide elastic buffering during adjustment. The fixed rods 224 at both ends of the bottom plate 223 penetrate through the base plate 221 and are slidably connected to it, guiding the stable expansion and contraction of the telescopic spring 222 to ensure the reliability of the elastic component 22. The outer end of the elastic component 22 is connected to the top of the connecting mechanism 61, realizing the stable connection of the entire angle adjustment mechanism 63 with other components, and finally realizing the flexible and stable adjustment of the specific angle and position of the face mask. At the same time, the buffer design can avoid excessive squeezing of the patient's face and the situation of excessive compression during wearing.

[0059] Such as Figures 5 to 8As shown, the connecting mechanism 61 includes a clamping frame 611 and a clamping block 612. The clamping blocks 612 are fixedly connected in a circumferential arrangement at equal intervals to the lower outer side of the mask body 1. The clamping frame 611 is fixedly connected to the bottom of the bottom plate 223. The clamping blocks 612 are inserted into the inside of the clamping frame 611. A clamping component 21 is provided on the inner side of the clamping frame 611. The clamping component 21 includes a concave frame 211 and a limiting groove 212. Limiting springs 213 are fixedly connected to both ends of the inner side of the concave frame 211. A push plate 214 is fixedly installed on the outer side of the limiting spring 213. A limiting block 215 is fixedly connected to the outer side of the push plate 214. The limiting groove 212 is opened on the outer side of the clamping block 612. The end of the limiting block 215 penetrates through the clamping frame 611 and is inserted into the inside of the clamping groove. A connecting shaft 216 is fixedly connected to the outer side of the push plate 214. The end of the connecting shaft 216 penetrates through the concave frame 211 and is fixedly connected to a pulling plate 217. The input end of the ventilation hose 5 is fixedly installed with a regulating valve 7. The regulating valve 7 is fixedly installed with a threaded joint 8 on the outer side. The clamping blocks 612 arranged in a circumferential arrangement at equal intervals on the lower outer side of the mask body 1 cooperate with the clamping frame 611 fixed to the bottom of the bottom plate 223. The clamping blocks 612 can be inserted into the inside of the clamping frame 611. The clamping component 21 on the inner side of the clamping frame 611 is used to lock the clamping blocks 612. The limiting springs 213 fixed to both ends of the concave frame 211 are connected to the outer side of the push plate 214. The push plate 214 is further connected to the limiting block 215. The limiting groove 212 is opened on the outer side of the clamping block 612. When the clamping block 612 is inserted into the clamping frame 611, under the action of the limiting spring 213, the end of the limiting block 215 penetrates through the clamping frame 611 and is inserted into the limiting groove 212 to complete the clamping and fixing. If it is necessary to disassemble, pull the pulling plate 217 at the end of the connecting shaft 216. The connecting shaft 216 drives the push plate 214 to compress the limiting spring 213, so that the limiting block 215 disengages from the limiting groove 212, and the clamping block 612 can be pulled out, which is convenient for quickly removing the mask body 1. In addition, the ventilation hose 5 and the regulating valve 7 are provided, and the gas flow can be controlled through the regulating valve 7 installed at the input end of the ventilation hose 5 during use. The threaded joint 8 on the outer side of the regulating valve 7 is used to connect to the ventilator to ensure stable gas delivery to the mask body 1.

[0060] As Figures 1 to 4As shown in the figure, the tightening mechanism 65 includes a rail frame 651 and a pull ring 652. The rail frame 651 is fixedly installed on the inner side of the ring body 62. The pull ring 652 is fixedly connected to the top of the connecting head 4. A lead screw 653 is rotatably connected inside the rail frame 651. The top of the lead screw 653 penetrates through the rail frame 651 and is fixedly connected to an adjusting handle 654. A movable plate 655 is threadedly connected to the outer surface of the lead screw 653. The movable plate 655 is movably connected inside the rail frame 651. A connecting frame 656 is fixedly connected to the bottom of the movable plate 655. A hook 657 is fixedly connected to the bottom of the connecting frame 656. The pull ring 652 is hung on the outer surface of the hook 657. The rail frame 651 is fixedly installed on the inner side of the ring body 62. The pull ring 652 is fixed to the top of the connecting head 4 and is hung on the outer surface of the hook 657. The hook 657 is connected to the connecting frame 656 at the bottom of the movable plate 655. The movable plate 655 is located inside the rail frame 651 and is threadedly connected to the lead screw 653. When the adjusting handle 654 at the top of the lead screw 653 is rotated, the lead screw 653 rotates accordingly. Since the lead screw 653 is threadedly connected to the movable plate 655, the rotation of the lead screw 653 will drive the movable plate 655 to move up and down inside the rail frame 651. In this way, the hook 657 can be driven to move up and down, thereby changing the position and force state of the pull ring 652, and further adjusting the tightness of the entire device to achieve the tightening operation of the ventilator mask, so that the fitting degree and tension of the mask can be adjusted to meet different usage requirements.

[0061] The working process of the technical solution provided by the present invention is as follows:

[0062] When in use, the mask body 1 is firmly bound to the patient's face with the help of the elastic strap 2; during use, the threaded connector 8 at the end of the ventilation hose 5 on the connector 4 is used to connect the ventilator. When the mask needs to be adjusted, the electric push rod 637 is started. After the electric push rod 637 is running, it pushes the bracket 635 and the adjusting wheel 634 to rotate. As the bracket 635 and the adjusting wheel 634 rotate, the mask body 1 begins to be pulled. Since the mask body 1 is made of highly elastic material and has good elasticity, it can be flexibly adjusted according to actual needs during use; for example, in the morning period, the electric push rod 637 is started, which pushes the hinge 638 to interact with the first hinge seat 632 and the second hinge seat 633, so that the bracket 635 expands outward. At noon, the electric push rod 637 is started to contract, driving the adjusting wheel 634 to make the bracket 635 contract inward, and the mask body 1 shrinks adaptively accordingly. When night comes, the electric push rod 637 is further started to contract, and the first hinge seat 632 and the second hinge seat 633 cooperate with the hinge 638 to move the bracket 635 further inward. During this period, the mask body 1 further shrinks and deforms. In this way, during the use of the mask, the opening degree of the mask body 1 can be adjusted according to different time periods to achieve the adjustment of the area of ​​the mask body 1. This function can effectively prevent the mask body 1 from always pressing on the same position of the patient's face when worn for a long time, thereby reducing the risk of pressure sores.

[0063] The setting of the connecting mechanism 61 provides convenience for cleaning and replacing the mask body 1. When the mask body 1 needs to be cleaned or replaced, the pull-out plate 217 is pulled, and the pull-out plate 217 drives the connecting shaft 216, and then the limit block 215 is pulled, and the limit block 215 presses the limit spring 213 to shrink it. At this time, the limit block 215 moves outward and disengages from the limit groove 212. After the limit groove 212 is separated from the limit block 215, the card block 612 can be pulled out from the inside of the card frame 611. After the card block 612 is disassembled, the mask body 1 can be removed by separating the hook 657 on the top of the mask body 1 from the pull ring 652. If the mask body 1 needs to be installed, the pull-out plate 217 is also pulled to drive the limit spring 213 to shrink. The block 215 compresses the limit spring 213 to compress the limit block 215 so that the limit block 215 is separated from the inner side of the card frame 611, and then the card block 612 on the mask body 1 is inserted into the card frame 611. After that, the pull-out plate 217 is released, the limit spring 213 is reset, and the push plate 214 is pushed to squeeze the limit block 215 so that it is inserted into the inner side of the limit groove 212. Through the mutual engagement and limiting of the limit block 215 and the limit groove 212, the card block 612 is firmly engaged and installed on the inner side of the card frame 611. Finally, the hook 657 and the pull ring 652 are hung with each other to complete the installation of the mask body 1. This design makes the mask body 1 of the present device easy to disassemble and assemble, which is beneficial to the subsequent replacement of the mask body 1 for daily maintenance and disinfection.

[0064] The provision of the elastic component 22 endows the device with good buffering performance during use. The telescopic spring 222 between the bottom plate 223 and the base plate 221 can play an auxiliary buffering role during use, providing a good buffering effect on the mask body 1. At the same time, the provision of the support rod 224 can guide the telescopic process of the telescopic spring 222 to ensure its stable telescoping, thereby making the overall device have good elasticity and improving the comfort of the mask body 1 during wearing.

[0065] The provision of the moving mechanism 64 provides more flexibility for the adjustment of the mask. When using this device, start the drive motor 234, and the drive motor 234 drives the gear 232 to rotate. Since the gear 232 is meshed with the toothed ring 233, as the gear 232 and the toothed ring 233 drive each other, the reverse drive slider 642 slides inside the annular groove 641. By driving the slider 642 to slide inside the annular groove 641, the rotation of the bracket 635 can be flexibly adjusted. After adjusting the rotation of the bracket 635, the bottom mask body 1 can be pulled, causing the mask body 1 to deform further, so as to better fit the faces of different patients. During use, in addition to adjusting through the drive motor 234, the adjustment handle 654 at the top can also be twisted to rotate it. The rotation of the adjustment handle 654 drives the lead screw 653 inside the rail frame 651 to rotate. The rotation of the lead screw 653 drives the movable plate 655 to slide up and down inside the rail frame 651. By adjusting the up and down sliding of the movable plate 655, the hook 657 at the bottom of the movable plate 655 is driven to move up and down. When the angle adjustment mechanism 63 adjusts the expansion of the mask body 1, the hook 657 is adjusted to move up, so that the entire mask body 1 can be further expanded; when adjusting the contraction of the mask body 1, the hook 657 is adjusted to move down to cooperate with the further contraction of the mask body 1. In this way, the mask body 1 can form a relatively stable structure during expansion and contraction, further ensuring its pressure ulcer prevention effect.
