Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a pressure ulcer care and pressure relief pad. Background Technology

[0002] Pressure ulcers, also known as pressure sores or bedsores, are soft tissue injuries or even necrosis caused by prolonged pressure on localized tissues, leading to impaired blood circulation, tissue ischemia, hypoxia, malnutrition, and ultimately, tissue damage. They are one of the most common complications in elderly bedridden patients and critically ill patients, increasing patient suffering, nurses' workload, and potentially prolonging hospital stays, thus increasing the economic burden on families and society. Reducing skin pressure can effectively prevent pressure ulcers. Current techniques typically use pads to elevate the areas requiring pressure relief, but this method requires lifting the patient's body first, placing the pad underneath, and removing the pad after a period of use—a cumbersome and inconvenient process. Furthermore, when different areas of the patient's body need pressure relief simultaneously, different parts cannot be raised at once; they must be raised gradually, which is also inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a pressure ulcer care pressure relief pad that can conveniently reduce the pressure on the patient's skin, and can also conveniently reduce the pressure on the patient's skin at different locations at the same time, thus preventing the formation of pressure ulcers.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A pressure ulcer care pressure relief pad includes a base pad, with a plurality of air bladders evenly spaced at the upper end of the base pad. A limiting groove is formed near each air bladder at the upper end of the base pad. A limiting shell is provided inside each limiting groove. A first limiting opening is formed on the front and rear sides of the upper end of each limiting shell. A horizontally arranged limiting plate is slidably connected inside each limiting shell. A first spring is provided between the lower end of each limiting plate and the corresponding limiting shell. A second limiting opening is formed on the front and rear sides of the upper end of each limiting plate. A vertically arranged limiting rod is slidably connected inside each first limiting opening and is slidably connected to each second limiting opening.

[0006] Each pair of limiting rods slidably connected to the same limiting shell has a horizontally arranged clamping block slidably connected between their upper ends. Each clamping block has a third limiting port on both the front and rear sides of its upper end. Each limiting rod is slidably connected to the corresponding third limiting port. Each limiting rod has a limiting block slidably connected to the corresponding clamping block at its upper end. A second spring is provided between each pair of limiting blocks slidably connected to the same clamping block. Each limiting rod has a locking block slidably connected to the corresponding first limiting port at its end away from the corresponding second spring. Each locking block has an inclined surface that slopes upward from bottom to top. A first air tube is provided at the upper end of the bottom pad near the limiting groove. A second air tube, which communicates with the corresponding airbag and the first air tube, is provided between each clamping block and the corresponding limiting shell. Each airbag has several silicone strips arranged at equal intervals at its upper end.

[0007] By adopting the above technical solution, during use, the airbag is placed on the hospital bed with a base pad, and then the patient lies down. The silicone strip on the airbag prevents the patient's skin from completely adhering to the airbag, increasing the breathability of the patient's skin. When pressure is needed on the patient's skin, airbags at different locations are inflated as required. For airbags that do not need to be inflated, pushing the clamping block causes the inclined surface on the clamping block to slide relative to the first limiting port, thereby causing the limiting rod to slide relative to the first limiting port. At the same time, the limiting rod slides relative to the third limiting port and the second limiting port. The limiting rod adjusts the sliding of the limiting block, compressing the second spring, and the clamping block moves downward. The limiting rod drives the limiting plate to slide relative to the limiting shell, compressing the first spring and causing the clamping block and limiting shell to clamp the second air tube. Under the action of the second spring, the locking block locks the first limiting port. By inflating the first air tube, the gas passes through the unblocked second air tube and enters the airbag that needs to be inflated. When it is not necessary to clamp the airbag, by pushing the limiting block to compress the second spring, the locking block is not locked at the first limiting port. Under the action of the first spring, the limiting plate slides, thereby causing the clamping block and limiting shell to release the corresponding second air tube, thus achieving simultaneous decompression of the skin at different locations on the human body.

[0008] A further feature of this invention is that each airbag is equipped with a heating belt inside, one end of the base pad is equipped with a power cord for connecting to a power source to provide power, and one end of the base pad is equipped with a controller for controlling the power supply of the heating belt.

[0009] A further feature of this invention is that a silicone block is provided at the lower end of each clamping block.

[0010] A further feature of this invention is that an inflator is provided at the free end of the first trachea.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] It allows for convenient adjustment of skin pressure at desired locations and simultaneous pressure relief at different locations, preventing pressure sores. By clamping different second tracheas, the inflation of airbags at different locations is controlled, elevating and depressing the skin. When clamping the second trachea, pushing the clamping block causes the inclined surface on the block to slide relative to the first limiting port, allowing the clamping block and limiting shell to clamp the second trachea. Under the action of the second spring, the clamping block locks the first limiting port in place. When releasing the second trachea, pushing the limiting rod causes the clamping block to release from the first limiting port. Under the action of the first spring, the clamping block and limiting shell release the second trachea, thus controlling the flow of gas through different second tracheas to inflate airbags at different locations.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Example, refer to Figure 1-4 A pressure ulcer care and pressure relief pad includes a base pad 1. Several air bladders 5 are evenly spaced on the upper end of the base pad 1. Several horizontally arranged silicone strips 6 are evenly spaced on the upper end of each air bladder 5 to increase the breathability of human skin. A heating band 19 is provided inside the upper end of each air bladder 5. A power cord 20 for connecting to a power source is provided on the right end of the base pad 1. A controller 21 for controlling the power supply of the heating band 19 is provided on the right end of the base pad 1, which can conveniently heat the skin of different parts of the human body.

[0023] On the upper left side of the base pad 1, there are several equally spaced limiting grooves 7 that correspond one-to-one with the airbags 5. Each limiting groove 7 has a limiting shell 8 inside. Each limiting shell 8 has a first limiting port 9 on both the front and rear sides of its upper end. Each limiting shell 8 has a horizontally arranged limiting plate 10 slidably connected inside. Each limiting plate 10 has a second limiting port 11 on both the front and rear sides of its upper end. Each limiting plate 10 has a first spring 12 between its lower end and the corresponding limiting shell 8, which can easily drive the limiting plate 10 to reset. Each first limiting port 9 has a vertically arranged limiting rod 15 slidably connected inside and slidably connected to the corresponding second limiting port 11.

[0024] A clamping block 13 is horizontally arranged between the upper ends of two limiting rods 15 that are slidably connected to the same limiting shell 8. A third limiting port 14 is opened on the front and rear sides of the upper end of each clamping block 13. Each limiting rod 15 is slidably connected to the corresponding third limiting port 14. A limiting block 17 is provided at the upper end of each limiting rod 15 that is slidably connected to the corresponding clamping block 13. A second spring 18 is provided between two limiting blocks 17 that are slidably connected to the same clamping block 13. A locking block 16 is provided at the end of each limiting rod 15 away from the second spring 18 that is slidably connected to the corresponding first limiting port 9. Each locking block 16 is provided with an inclined surface that is inclined from bottom to top, which can facilitate adjustment of the required airbag 5, thereby facilitating skin decompression at the required position of the patient.

[0025] A first air tube 3 is provided on the right side of the upper end of the base pad 1. A second air tube 4 is provided between each silicone block 22 and the corresponding limiting shell 8, which is connected to the corresponding airbag 5 and the first air tube 3. A silicone block 22 is provided between the lower end of each clamping block 13 and the corresponding two third limiting ports 14, which can ensure that the second air tube 4 is fully clamped. An inflator 2 is provided at the end of the first air tube 3 away from the base pad 1.

[0026] Usage: When in use, place the base pad 1 onto the hospital bed, then have the patient lie down. The silicone strip 6 on the airbag 5 prevents the patient's skin from completely adhering to the airbag 5, increasing the breathability of the patient's skin. When pressure is needed on the patient's skin, inflate the airbags 5 at different locations as required. For airbags 5 that do not need to be inflated, push the clamping block 13, causing the inclined surface on the locking block 16 to slide relative to the first limiting port 9, thereby causing the limiting rod 15 to slide relative to the first limiting port 9. At the same time, the limiting rod 15 slides relative to the third limiting port 14 and the second limiting port 11. The limiting rod 15 moves the limiting block 17 to slide, compressing the second spring 18. The clamping block 13 moves downward, and the limiting plate 10 slides relative to the limiting shell 8 through the limiting rod 15, compressing the first spring 12. This causes the silicone block 22 and the limiting shell 8 to clamp the second air tube 4. Under the elastic force of the second spring 18, the locking block 16 locks the first limiting port 9. Then, the inflator 2 is started. The gas generated by the inflator 2 passes through the first air tube 3, then through the unblocked second air tube 4, and enters the airbag 5 that needs to be inflated, thereby achieving simultaneous decompression of the skin at different locations on the human body.

[0027] When the airbag 5 is not needed, the second spring 18 is compressed by pushing the limiting block 17, causing the locking block 16 to not block the first limiting port 9. Under the elastic force of the first spring 12, the limiting plate 10 is slid, thereby allowing the clamping block 13 and the limiting shell 8 to release the corresponding second air tube 4. By connecting the power cord 20 to the power supply, the controller 21 can control the power supply to the heating belt 19 to heat the human skin and prevent pressure sores from forming.

[0028] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
