Description

Technical Field

[0001] The present invention relates to the field of medical care, and more particularly to a care device for foot pressure injuries. Background Art

[0002] Pressure injury of the foot, also known as pressure sores or bedsores, is a condition in which the skin and its deeper tissues become damaged, such as ischemia, hypoxia, and necrosis, due to long-term pressure, friction, or shear force on the feet. Long-term external pressure on the feet, such as an inappropriate mattress when lying in bed, standing or walking for long periods of time, etc., can cause local tissue ischemia and hypoxia, resulting in pressure injury to the feet.

[0003] Clinically, the most common foot pressure care is to elevate the patient's feet to promote blood circulation, thereby reducing the pressure of foot swelling and pain. This method is more suitable for patients who are bedridden for a long time, but it is not suitable for patients who need to perform appropriate activities. It is particularly important to use devices to fix and protect the patient's feet as necessary, while maintaining a flexible connection between the patient's lower limbs and the care device. Moreover, the specific size and structure of the feet of different patients are different, and the shapes of the left and right feet are also different, so the care device for foot pressure injuries requires a higher level of universality.

[0004] Based on the above technical problems, the prior art also provides some solutions. For example, the Chinese patent with the authorization announcement number CN117045415A discloses a nursing device for pressure injuries of the foot. The device solves the problem that the existing nursing devices are not universal and cannot be applied to the care of different foot sizes of different patients and between left and right feet. In addition, the existing nursing devices are difficult to use and difficult to install and disassemble.

[0005] However, in actual production operations, the above-mentioned device is difficult to adapt to patients with different sizes of feet. The existing device can only perform simple tightness adjustment. At the same time, when the patient lifts the foot after wearing the care device, the care device will be in contact with the patient's foot for a long time, which will cause compression and blood circulation problems. At the same time, long-term close wrapping will cause friction and compression on the skin, causing skin damage. The environment of the close wrapping is relatively closed, which is prone to bacterial growth and increased risk of infection. Summary of the invention

[0006] In view of the problem in the prior art that long-term close fitting wrapping may cause skin damage due to friction and pressure, and the problem that the close fitting wrapping environment is relatively closed, the purpose of the present invention is to provide a care device for pressure injuries of the feet.

[0028] While the top ventilation fan rotates to improve the ventilation in the right support frame, the air guide groove can reduce the coldness caused by the top ventilation fan blowing directly on the foot. By improving the ventilation effect in the right support frame, the growth of bacteria during long-term care can be reduced, the risk of infection is reduced, and the patient's protection during the care of foot pressure injuries is improved.

[0029] After generating heat in the heating box, the top vent fan will blow the hot air in the heating box upward along the air guide groove when it rotates, which can improve the comfort of the patient's feet during the care process. The warm air can accelerate blood circulation in the feet, help relieve foot fatigue and discomfort caused by pressure injuries. At the same time, hot air can keep the wound dry, which helps to accelerate the recovery process of pressure injuries of the feet.

[0030] During the rotation of the top vent fan, the dust screen in the protective frame reduces the dust and other particles from entering the heating box, reduces the dust particles blown toward the patient's feet, and reduces bacterial infection. At the same time, the surface of the dust screen is cleaned by the cleaning brush on one side of the transmission block, and the dust particles accumulated and blocked on the surface of the dust screen are cleared, thereby improving the cleaning effect.

[0031] The rotating massage mechanism will come into contact with the soles of the patient's feet, and can massage the soles of the patient's feet. Through rotation and pressing, it can stimulate blood circulation, improve the nutrition supply to the nerves, thereby promoting the recovery of injuries and improving the patient's recovery effect.

[0032] Finally, the disinfection lamp is driven by the battery body to start, and the sole of the foot is disinfected regularly after the disinfection lamp is started. At the same time, the controller can drive the starting time of the disinfection lamp, thereby reducing bacterial growth and improving protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] The top of the bottom transmission rod 705 is rotatably connected to the output end of the DC motor 704. A first toothed disc 706 is installed at the bottom end of the bottom transmission rod 705. A second toothed disc 707 is installed at one end of the side transmission rod. The first toothed disc 706 is meshed with the second toothed disc 707. A third toothed disc 709 is installed at the other end of the side transmission rod. The fan assembly includes a top ventilation fan 7011. A fourth toothed disc 7010 is installed at the bottom of the top ventilation fan 7011. The fourth toothed disc 7010 is meshed with the third toothed disc 709.

[0076] The top of the protective bottom box 7014 is fixedly connected with a top limit plate 7013, and the bottom of the top limit plate 7013 is rotatably connected with a bearing plate 7012, and the bottom of the bearing plate 7012 is rotatably connected to the top of the center of the top ventilation fan 7011. The top limit plate 7013 limits the top ventilation fan 7011. Since the protective bottom box 7014 is connected to the upper surface of the support platform 1 through the air guide groove 7016, when the top ventilation fan 7011 works in the protective bottom box 7014, the generated airflow is blown to the support base pad 5 on the upper surface of the support platform 1 through the air guide groove 7016 to ventilate the feet. The movable connection of the bearing plate 7012 can improve the rotation stability of the top ventilation fan 7011.

[0077] After the DC motor 704 in the power box 701 is started, the DC motor 704 can drive the bottom transmission rod 705 to rotate, and the bottom transmission rod 705 can drive the No. 1 gear plate 706 to rotate after the rotation, and the rotating No. 1 gear plate 706 will drive the No. 2 gear plate 707 to rotate, and the rotating No. 2 gear plate 707 will drive the side transmission rod 708 to rotate, and the rotating side transmission rod 708 will drive the No. 3 gear plate 709 to rotate synchronously, and the side transmission rod 708 will be supported by the No. 1 limiting hole 7015 during the rotation process, and the No. 3 gear plate 709 can be meshed with the No. 4 gear plate 7010 to rotate on the No. 3 gear plate. When 709 rotates, it drives the fourth gear disc 7010 and the top ventilation fan 7011 to rotate. At this time, the top ventilation fan 7011 will generate wind after rotating in the protective bottom box 7014. The generated wind will be blown upward along the air guide groove 7016. The direction of the wind is changed by opening the air guide groove 7016. While the ventilation is improved after the top ventilation fan 7011 rotates, the cold caused by the top ventilation fan 7011 blowing directly on the foot can be reduced. By improving the ventilation effect, the growth of bacteria in the long-term care process can be reduced, the risk of infection is reduced, and the patient's protection against foot pressure injuries during care is improved.

[0078] like Figures 3 to 9 As shown, the heating assembly includes a heating box 801, which is installed at the bottom of the protective bottom box 7014 and connected to the protective bottom box 7014, one side of the heating box 801 is electrically connected to a temperature controller 804, the temperature controller 804 is electrically connected to an overheat protector 805, a support seat 802 is provided inside the heating box 801, a heating wire 803 is installed inside the support seat 802, the temperature controller 804 is electrically connected to the heating wire 803, and a dust screen 808 is provided on the side of the heating box 801 close to the threaded rod 403.

[0079] After the heating wire 803 in the support seat 802 is driven to work by the temperature controller 804, the heating wire 803 can be started and generate heat. At the same time, the temperature can be monitored by the temperature controller 804, and the temperature in the heating box 801 can be controlled by the start-stop method. The overheat protector 805 is used to automatically cut off the power supply when the equipment is overheated. After heat is generated in the heating box 801, since the protective bottom box 7014 is connected to the heating box 801, when the top vent fan 7011 rotates, the hot air in the heating box 801 will be blown upward along the air guide groove 7016, which can improve the comfort of the patient's feet during the nursing process. The warm air can accelerate blood circulation in the feet, help relieve foot fatigue and discomfort caused by pressure injuries. At the same time, the hot air can keep the wound dry, which helps to accelerate the recovery process of pressure injuries of the feet.

[0080] like Figures 1 to 13As shown, the massage mechanism includes at least one massage component. In this embodiment, there are two massage components.

The first bottom fixed rod has a bottom gear 1014, which rotates with the first bottom transmission rod, and the bottom gear 1014 is meshed with the rack 1015, and the rack 1015 is also meshed with a top gear 1016, that is, the top gear 1016 is connected to the bottom gear 1014 through the rack 1015, and the rotation of the bottom gear 1014 drives the top gear 1016 to rotate, and the top gear 1016 is sleeved on the second bottom fixed rod, that is, the rotation of the top gear 1016 drives the second fixed rod to rotate, so that the first bottom fixed rod and the second bottom fixed rod rotate synchronously. The bottom gear 1014, the rack 1015 and the top gear 1016 are all located outside the first support frame 2, the first bottom fixed rod passes through the second limiting hole 1009 on the first support frame 2 and is connected to the bottom gear 1014, and the second bottom fixed rod passes through the second limiting hole 1009 on the first support frame 2 and is connected to the top gear 1016.

[0081] Since the massage components have the same structure, the structure on the first bottom fixed rod is taken as an example below, and the structure on the second bottom fixed rod is the same as the structure of the first bottom fixed rod. The massage component includes a sleeve column 1004 and a fixed frame. There is at least one sleeve column 1004, and in this embodiment, there are two sleeve columns 1004. Two sleeve columns 1004 are sleeved on the first bottom fixed rod in sequence. On each sleeve column 1004, at least two connection frames 1005 are evenly installed on the outer peripheral surface of the ring sleeve column 1001. In this embodiment, four connection frames 1005 are installed on each sleeve column 1004. On the connection frame, a massage column 1006 is installed on the side away from the sleeve column 1004, and a plurality of massage modules 1007 are evenly arranged on the surface of the massage column 1006. A fixed frame is fixedly installed on the inner side of the first support frame 2, and the fixed frame is located on one side of the first bottom fixed rod and is parallel to the first bottom fixed rod (a fixed frame is also provided on one side of the second bottom fixed rod). The fixed frame includes two parallel connecting rods 1011 and two parallel side fixing rods 1010. The rectangular frame obtained by connecting the side fixing rods 1010 and the connecting rods 1011 is the fixed frame. An elastic belt 1012 is installed in the fixed frame. The elastic belt 1012 is a rectangular cloth. Communication holes 1013 are respectively opened on both sides of the two length edges of the elastic belt 1012. The two length edges of the elastic belt 1012 are respectively sleeved on the two connecting rods 1011 through the communication holes 1013. The fixed frame and the elastic belt 1012 are close to the massage column 1006. At least one massage column 1006 on each sleeve column 1004 is in contact with the elastic belt 1012.

[0082] When the DC motor 704 is started and drives the bottom transmission rod 705 to rotate, the rotation of the bottom transmission rod 705 will drive the fifth gear disc 1001 to rotate, and the engagement of the fifth gear disc 1001 with the sixth gear disc 1002 can drive the bottom fixing rod 1003 on one side of the sixth gear disc 1002 to rotate, and the rotating bottom fixing rod 1003 will drive the sleeve column 1004 to rotate synchronously, and when the sleeve column 1004 rotates, it will drive multiple connection frames 1005 and massage columns 1006 to rotate along the sleeve column 1004. The center of the circle rotates in a circle, and the rotating massage column 1006 will continuously push the surface of the elastic belt 1012 to move, and one side of the elastic belt 1012 is in contact with the sole of the patient's foot. At the same time, the elastic belt 1012 is elastic. When the massage block 1007 on the surface of the massage column 1006 continuously moves to push the elastic belt 1012, the sole of the patient's foot can be massaged, and the bottom fixed rod 1003 will drive the bottom gear 1014 to rotate when rotating, and through the meshing connection of the rack 1015, the bottom gear 1014 can be rotated. When the top gear 1016 rotates, the bottom fixed rod 1003, the sleeve column 1004, the connecting frame 1005, the massage column 1006, the massage block 1007, the second bearing plate 1008, the second limiting hole 1009, the side fixed rod 1010, the connecting rod 1011 and the elastic belt 1012 are each provided with two groups. The two groups of massage columns 1006 can be driven to rotate through the transmission of the bottom gear 1014, the rack 1015 and the top gear 1016, and the elastic belt 1012 can massage the sole of the patient's foot. While supporting, the patient's foot can be massaged. Through rotation and pressing, blood circulation can be stimulated, and the nutrition supply to the nerves can be improved, thereby promoting the recovery of the injury and improving the patient's recovery effect. One end of the two bottom fixing rods 1003 is movably connected with a No. 2 bearing disk 1008. When the No. 2 bearing disk 1008 contacts the No. 2 limiting hole 1009, the No. 2 limiting hole 1009 can be used to support and limit the No. 2 bearing disk 1008, which can improve the stability of the bottom fixing rod 1003 during rotation.

[0083] The side of the support platform 1 away from the transmission assembly is provided with a bottom connection block 4014. In this embodiment, there are two bottom connection blocks 1014, which are arranged in parallel. A guide hole 4015 is provided in the bottom connection block 1014. Two parallel guide rods 4016 are installed at the bottom of the second support frame 406. The two guide rods 4016 correspond to the two guide holes 4015 respectively, and one end of the two guide rods 4016 is slidably connected to the two guide holes 4015. When the second support frame 406 moves, the guide rods 4016 are driven to slide in the guide holes 4015.

[0084] The sliding of the guide hole 4015 and the guide rod 4016 can improve the stability of the horizontal movement of the second supporting frame 406.

[0085] like Figures 7 and 8 As shown, an air intake frame 806 is provided on one side of the heating box 801 close to the threaded rod 403, a protective frame 807 is installed on the inner circumference of the air intake frame 806, and a dust screen 808 is installed in the protective frame 807; a sliding rail 906 is provided on the inner edge of the air intake frame, and a cleaning mechanism is provided on one side of the heating box 801; the cleaning mechanism includes a side transmission plate 901, a No. 2 threaded sleeve 902 is provided on the top of the side transmission plate 901, the No. 2 threaded sleeve 902 is threadedly connected to the threaded rod 403, and the side transmission plate 901 moves linearly on the threaded rod 403 through the No. 2 threaded sleeve 902, and the principle is similar to the screw movement and will not be repeated here. A transmission block 903 is installed on one side of the bottom end of the side transmission plate 901, and sliding blocks 905 are respectively provided at the top and bottom ends of the transmission block 903. A cleaning brush 904 is provided on the side of the transmission block 903 close to the dust screening net 808; the transmission block 903 is slidably connected to the sliding rail 906 through the sliding block 905. When the transmission block 903 slides on the sliding rail 906, the cleaning brush 904 contacts the dust screening net 808 and cleans the dust screening net.

[0086] During the rotation of the top ventilation fan 7011, external air will be drawn into the heating box 801 along the air intake frame 806, and the dust and other particles entering the heating box 801 will be reduced through the dust shield 808 in the protective frame 807. This can reduce the dust particles blown toward the patient's feet along the air guide groove 7016 and reduce bacterial infection.

[0087] During the process of the transmission motor 402 driving the second support frame 406 to move horizontally, through the threaded connection between the No. 2 threaded sleeve 902 and the threaded rod 403, the side transmission plate 901 can be driven to move horizontally synchronously during the process of the threaded rod 403 rotating to adjust the horizontal position of the second support frame 406. During the horizontal movement, the side transmission plate 901 will drive the transmission block 903 to move horizontally along one side of the air intake frame 806. At this time, the surface of the dust screen 808 can be cleaned by the cleaning brush 904 on one side of the transmission block 903, and the dust particles accumulated and blocked on the surface of the dust screen 808 can be cleaned. At the same time, during the horizontal movement of the transmission block 903, the sliding of the sliding block 905 and the sliding rail 906 can improve the stability of the horizontal movement of the transmission block 903.

[0088] like Figures 1 to 13As shown, a disinfection mechanism is installed on the second support frame 406, and the disinfection mechanism includes a connecting frame 1101, and the connecting frame 1101 includes a first connecting frame and a second connecting frame, and the lamp holder 1102 includes a first lamp holder and a second lamp holder, and the second supporting frame 406 and the first supporting frame 2 are respectively provided with a second connecting frame and a first lamp holder and a second lamp holder are respectively installed on the inner side of the first connecting frame and the inner side of the second connecting frame, and the controller body 1103 and the battery body 1104 are installed on the first lamp holder, and a disinfection lamp 1105 is installed in the second lamp holder, and a protective outer frame 1106 is installed on one side of the second lamp holder, and the protective outer frame 1106 is located on the outer side of the disinfection lamp 1105 for protecting the disinfection lamp 1105. The battery body 1104 is installed on the top of the second lamp holder.

[0089] After the disinfection lamp 1105 is started by the battery pack 1104, the disinfection lamp 1105 is fixed by the second lamp holder in the second connecting frame opened on the surface of the second support frame 406. After the disinfection lamp 1105 is started, the sole of the foot is disinfected regularly. During the disinfection process, the start time of the disinfection lamp 1105 can be driven by the controller body 1103. The controller body 1103 controls the disinfection lamp 1105 to perform disinfection regularly, which can reduce the impact on the patient's skin, reduce bacterial growth, and improve protection.

[0090] The working process of the technical solution provided by the present invention is as follows:

[0091] First, the transmission motor 402 is started, and the transmission motor 402 on the side of the first side fixing frame 401 drives the threaded rod 403 to rotate, and drives the fixed bottom plate 404 to move horizontally along the surface of the threaded rod 403, driving the second supporting frame 406 to move along the threaded rod 403 to the side of the first supporting frame 2. When the second supporting frame 406 moves, it will drive the second clamping L plate 407 and the second clamping plate 4010 to move synchronously, and the second connecting plate 4010 will contact the first limiting slide 4013 on the side of the first limiting L frame 4011 on the side of the first supporting frame 2. The first clamping plate 4012 on one side of the first supporting frame 2 will contact and limit the second limiting slide 409, wrap and support the back part of the patient's ankle, and the patient's skin surface will contact the soft support pad 408, thereby improving the comfort during the support process. By using a portable position-adjustable clamping mechanism 4 to clamp the back of the patient's ankle and support the patient's heel, the friction and pressure on the skin caused by the traditional wrapping and lifting methods are reduced, thereby improving the portability and comfort of nursing for pressure injuries of the patient's feet.

[0092] After the DC motor 704 in the power box 701 is started, the top ventilation fan 7011 will be driven to rotate, and the generated wind will be blown upward along the wind guide groove 7016, and blown toward the inner side of the first supporting frame 2 along the wind guide groove 7016. The direction of the wind is changed by opening the wind guide groove 7016. When the top ventilation fan 7011 rotates, the ventilation in the clamping mechanism is improved, and the cold caused by the top ventilation fan 7011 blowing directly on the foot surface can be reduced. By improving the ventilation effect in the clamping mechanism, the growth of bacteria in the long-term care process is reduced, the risk of infection is reduced, and the protection of patients against foot pressure injuries during care is improved.

[0093] After the heating wire 803 in the support seat 802 is driven to work by the temperature controller 804, heat is generated in the heating box 801. When the top ventilation fan 7011 rotates, the hot air in the heating box 801 is blown upward along the air guide groove 7016, which can improve the comfort of the patient's feet during the nursing process. The warm air can accelerate the blood circulation of the feet, help relieve the discomfort caused by foot fatigue and pressure injuries, and at the same time, the hot air can keep the wound dry, which helps to accelerate the recovery process of foot pressure injuries.

[0094] During the rotation of the top ventilation fan 7011, the dust and other particles entering the heating box 801 are reduced by the dust screen 808 in the protection frame 807, which can reduce the dust particles blowing toward the patient's feet along the air guide groove 7016 and reduce bacterial infection. At the same time, the surface of the dust screen 808 is cleaned by the cleaning brush 904 on one side of the transmission block 903, and the dust particles accumulated and blocked on the surface of the dust screen 808 are cleaned. At the same time, during the horizontal movement of the transmission block 903, the sliding block 905 and the sliding rail 906 can slide, which can improve the stability of the horizontal movement of the transmission block 903.

[0095] When the DC motor 704 is started and the bottom transmission rod 705 is driven to rotate, the multiple connection frames 1005 and the massage column 1006 will be driven to rotate in a circle along the center of the sleeve column 1004. The rotating massage column 1006 will continuously push the surface of the elastic belt 1012 to move, and one side of the elastic belt 1012 is in contact with the sole of the patient's foot, so as to massage the sole of the patient's foot. Through rotation and pressing, blood circulation can be stimulated, and the nutrition supply of the nerves can be improved, thereby promoting the recovery of the injury and improving the recovery effect of the patient.

[0096] Finally, after the disinfection lamp 1105 is driven by the battery pack 1104 to start, the sole of the foot is disinfected regularly. During the disinfection process, the controller body 1103 can drive the start time of the disinfection lamp 1105, thereby reducing bacterial growth and improving protection.

[0097] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0098] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
