Abstract
Description
Technical Field
[0001] This utility model relates to the medical field, specifically an anti-pressure ulcer pad. Background Technology
[0002] Pressure ulcer prevention air cushions are a type of pressure ulcer prevention cushion. They work by continuously inflating the air bladder with an air pump, which increases the pressure area on the body and disperses the pressure, thereby improving blood circulation and normal oxygen supply to the skin. This effectively prevents pressure ulcers and is suitable for patients who are bedridden for extended periods.
[0003] For example, in the patent application number CN202321205064.6, the patent title is "A Multifunctional Anti-Pressure Ulcer Air Mattress Bed", which includes a bed board, an air mattress and an air delivery device; the air mattress includes a leg-lifting air chamber, a leg-raising air chamber, a back-raising air chamber, a turning air chamber, a first-cycle inflation / deflation air chamber and a second-cycle inflation / deflation air chamber, and has the functions of back-raising, turning over, leg and arm rehabilitation training and preventing pressure ulcers.
[0004] However, the applicant has found that while existing pressure ulcer prevention air mattresses can effectively prevent pressure ulcers, the long-term contact between the patient and the inflated air bladder may cause a lot of germs to accumulate at the contact point, which is detrimental to the patient's health. However, since the patient's body is difficult to move, cleaning the surface of the air bladder is very inconvenient. Therefore, it is necessary to propose a pressure ulcer prevention mat to solve the above-mentioned technical problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide an anti-pressure ulcer pad to solve the technical problem in the prior art that when cleaning is required at the contact point between the airbag and the patient, the cleaning work is very inconvenient because the patient's body is difficult to move.
[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:
[0007] An anti-pressure sore pad includes a base pad, the upper surface of which is provided with a plurality of parallel grooves; the anti-pressure sore pad further includes:
[0008] Several sliding plates that match the chute;
[0009] A support airbag is provided on the skateboard, and the support airbag is provided with an inflation port and an air outlet port;
[0010] An air inlet pipe and an air outlet pipe are provided. The air inlet end of the air inlet pipe is used to connect to the air outlet end of the air pump, and the air outlet end of the air outlet pipe is used to connect to the air inlet end of the air pump. The air inlet pipe is provided with several first branch pipes communicating with it. The first branch pipe is provided with a first on / off valve and is used to communicate with the air filling interface. The air outlet pipe is provided with several second branch pipes communicating with it. The second branch pipe is provided with a second on / off valve and is used to communicate with the air outlet interface.
[0011] At least one wheel assembly disposed on the upper surface of the skateboard, the wheel assembly including a plurality of guide wheels, wherein when the skateboard is located in the groove and the support airbag is filled with gas, the distance from the top of the support airbag to the upper surface of the skateboard is greater than the maximum distance from the guide wheels to the upper surface of the skateboard.
[0012] Furthermore, the wheel assembly is provided in two symmetrical arrangements, forming an airbag space between the two wheel assemblies; when the supporting airbag is not inflated, it is located within the airbag space.
[0013] Furthermore, the chute is a T-shaped chute, the bottom of the slide plate matches the chute, and the chute has an opening on one side of the base pad to allow the slide plate to enter the chute.
[0014] Furthermore, the anti-pressure sore pad also includes screws that correspond one-to-one with the slide grooves. The bottom surface of the slide groove near the opening is provided with a screw hole. The screws match the screw holes and are used to limit the slide plate located in the slide groove.
[0015] Furthermore, the pressure ulcer prevention pad also includes an auxiliary airbag and several top rods. The slide plate has an inner cavity, the top rods are slidably connected to the inner cavity, and the support airbag is located on the top of the top rod. The auxiliary airbag is located on the lower surface of the support airbag, and the two are connected.
[0016] Furthermore, after the support airbag is filled with gas, the width of the support airbag is greater than the width of the upper surface of the skateboard.
[0017] Furthermore, after the support airbag is filled with gas, the side surface of the guide wheel contacts the lower surface of the support airbag.
[0018] Furthermore, the guide wheel is made of a flexible material.
[0019] The beneficial effects of this utility model are as follows: Using this device, firstly, the base pad is placed on the bed. Then, several sliding plates are slid sequentially along the grooves onto the base pad. Next, the first branch pipe is connected to the corresponding inflation port, and the second branch pipe is connected to the corresponding air outlet port. Finally, the first and second on / off valves are opened. After completion, the air pump is started. After each support airbag is filled with gas, the upper surface of each support airbag forms a flat surface for the patient to lie on. When it is necessary to clean the surface of the support airbags, all support airbags need to be removed from the base pad sequentially for cleaning. The main process is as follows: [The text abruptly ends here, likely due to an incomplete sentence or missing information.] When cleaning one of the support airbags, first close the first and second on / off valves corresponding to that support airbag. Then, separate the first branch pipe from the inflation port and the second branch pipe from the air outlet port. This will release the gas inside the support airbag. Since the surrounding adjacent support airbags are still full of gas, this support airbag will not be compressed by the patient's body. Eventually, the support airbag will gradually contract due to the release of gas until the guide wheel contacts the patient. The reason the guide wheel contacts the patient is that the patient's fat, after being squeezed, will fill the gap after the support airbag contracts. Finally, the slide can be removed by following the chute. During the removal process, the friction between the slide and the patient is greatly reduced due to the rolling action of the guide wheels, greatly reducing patient discomfort. After removal, the surface of the support airbag is cleaned. After cleaning, the slide is pushed back into the chute along the chute. The first branch pipe is then reconnected to the corresponding inflation port, and the second branch pipe is connected to the corresponding air outlet port. The corresponding first and second on / off valves are then opened to re-inflate the support airbag. This completes the cleaning of one support airbag. The remaining support airbags can be cleaned in the same way. With this device, when the support airbag needs to be cleaned at the point of contact with the patient, the caregiver can easily complete the cleaning of the support airbag surface without the patient moving.

[0025] As attached Figure 1 , Figure 2 As shown, this utility model includes: an anti-pressure sore pad, including a base pad 3, the upper surface of which is provided with a plurality of parallel grooves 5; the anti-pressure sore pad also includes:
[0026] Several sliding plates 6 that match the slide rail 5;
[0027] The support airbag 4 is provided on the skateboard 6. The support airbag 4 is provided with an inflation port and an air outlet.
[0028] The air inlet pipe 1 and the air outlet pipe 2 are provided. The air inlet end of the air inlet pipe 1 is used to connect to the air outlet end of the air pump, and the air outlet end of the air outlet pipe 2 is used to connect to the air inlet end of the air pump. The air inlet pipe 1 is provided with several first branch pipes connected to it. The first branch pipe is provided with a first on / off valve and is used to connect to the inflation interface. The air outlet pipe 2 is provided with several second branch pipes connected to it. The second branch pipe is provided with a second on / off valve and is used to connect to the air outlet interface.
[0029] At least one wheel assembly is provided on the upper surface of the skateboard 6. The wheel assembly includes a plurality of guide wheels 10. When the skateboard 6 is located in the groove 5 and the support airbag 4 is filled with gas, the distance from the top of the support airbag 4 to the upper surface of the skateboard 6 is greater than the maximum distance from the guide wheels 10 to the upper surface of the skateboard 6.
[0030] In this embodiment, the base pad 3 is first placed on the bed, and then several sliding plates 6 are slid sequentially along the sliding groove 5 onto the base pad 3. Next, the first branch pipe is connected to the corresponding inflation port, and the second branch pipe is connected to the corresponding air outlet port. Finally, the first and second on / off valves are opened. After completion, the air pump is started. After each support airbag 4 is filled with gas, the upper surface of each support airbag 4 forms a flat surface for the patient to lie on. When it is necessary to clean the surface of the support airbag 4, all support airbags 4 need to be removed from the base pad 3 sequentially for cleaning. The main process is as follows: when cleaning a specific support airbag... When cleaning the airbag 4, first close the first and second on / off valves corresponding to the supporting airbag 4, then separate the first branch pipe from the inflation port and the second branch pipe from the air outlet port. In this way, the gas inside the supporting airbag 4 will be discharged. Since the surrounding adjacent supporting airbags 4 are still full of gas, the supporting airbag 4 will not be pressed by the patient's body. Eventually, the supporting airbag 4 will gradually contract due to the release of gas until the guide wheel 10 contacts the patient. The reason why the guide wheel 10 contacts the patient is that the patient's fat will fill the gap after the supporting airbag 4 contracts after being squeezed. Finally, the slide plate 6 can be removed along the slide groove 5. During the removal process, the friction between the slide plate 6 and the patient is greatly reduced due to the rolling action of the guide wheel 10, significantly reducing patient discomfort. After removal, the surface of the support airbag 4 is cleaned. After cleaning, the slide plate 6 is pushed back into the slide groove 5. The first branch pipe is then reconnected to the corresponding inflation port, and the second branch pipe is connected to the corresponding air outlet port. The corresponding first and second on / off valves are then opened to re-inflate the support airbag 4. This completes the cleaning of one support airbag 4. The remaining support airbags 4 can be cleaned using the same steps. With this device, when the contact area between the support airbag 4 and the patient needs cleaning, the caregiver can easily complete the cleaning of the surface of the support airbag 4 without the patient moving. The first and second on / off valves can be solenoid valves.
[0031] In addition, such as Figure 2 , Figure 4 As shown, there are two wheel assemblies, which are symmetrically arranged, and an airbag space is formed between the two wheel assemblies. When the support airbag 4 is not inflated, it is located in the airbag space. After the airbag 4 is released, it is supported by the wheel assemblies on both sides, which can improve the patient's comfort.
[0032] To better facilitate the entry and exit of the skateboard 6 into and out of the slide rail 5, such as Figure 1 , Figure 2 As shown, the slide 5 is a T-shaped groove, and the bottom of the slide plate 6 matches the slide 5. The slide 5 has an opening on one side of the base pad 3 so that the slide plate 6 can enter the slide 5.
[0033] In addition, such as Figure 1 , Figure 3As shown, the anti-pressure sore pad also includes screws 11 that correspond one-to-one with the slide groove 5. The bottom surface of the slide groove 5 near the opening is provided with screw holes 12. The screws 11 and screw holes 12 are matched to limit the slide plate 6 located in the slide groove 5.
[0034] As one implementation method, such as Figure 1 , Figure 2 As shown, the pressure ulcer prevention pad also includes an auxiliary airbag 9 and several push rods 8. The slide plate 6 has an inner cavity 7 inside. The push rods 8 are slidably connected to the inner cavity 7. The support airbag 4 is located on the top of the push rod 8. The auxiliary airbag 9 is located on the lower surface of the support airbag 4, and the two are connected.
[0035] In this embodiment, after the slide plate 6 is located in the slide groove 5, the initial position of the bottom of the push rod 8 contacts the bottom of the inner cavity 7, so that the support airbag 4 and the auxiliary airbag 9 are both located in the airbag space. When inflated, both the support airbag 4 and the auxiliary airbag 9 will expand. When the auxiliary airbag 9 collides, the push rod 8 will slowly slide upward, so that the support airbag 4 will eventually leave the airbag space. After the support airbag 4 is deployed, it is located above the guide wheel 10.
[0036] As one implementation method, such as Figure 2 As shown, after the support airbag 4 is filled with gas, the width of the support airbag 4 is greater than the width of the upper surface of the slide plate 6 to prevent the patient from being in contact with the guide wheel 10 for a long time.
[0037] In addition, such as Figure 2 As shown, after the support airbag 4 is filled with gas, the side surface of the guide wheel 10 contacts the lower surface of the support airbag 4, so that when the support airbag 4 is fully deployed, it can assist in supporting the patient.
[0038] The guide wheel 10 is made of flexible material to increase patient comfort.
