Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of protective knee, specifically is a kind of anti-pressure sore protective knee. BACKGROUND

[0002] High incidence of pressure sores: with the social population aging, cardiovascular and cerebrovascular diseases and the increase of late-stage cancer, bedridden patients and seriously ill patients are increasing, and the incidence of pressure sores is also rising. Medical reports at home and abroad show that the incidence of pressure sores in general hospitals is 3.1%-14.1%, the incidence of pressure sores in hospitalized elderly is 11.0%-26.0%, and the incidence of pressure sores in critically ill patients is about 24%. In particular, the incidence of pressure sores in elderly patients can reach 10%-25%. Pressure sores not only affect the quality of life of patients, but also can cause serious complications. Due to the loss of skin barrier function, the wound is exposed and often contaminated by feces and urine, and the infection rate is very high, including abscess, osteomyelitis and sepsis, etc. These complications can lead to high mortality under hospital conditions, and pressure sores are the "number one killer" of long-term bedridden patients. Pressure sores are difficult to treat and prone to recurrence. Once formed, it is often difficult to cure quickly and is prone to repeated attacks, causing great pain and distress to patients.

[0003] The anti-pressure sore protective knee is a nursing aid designed specifically for patients who are long-term bedridden, cannot turn over by themselves or have limited lower limb mobility. It aims to prevent the occurrence of pressure sores, which are a phenomenon of ulceration and necrosis caused by long-term pressure on local tissues, leading to blood circulation disorders, tissue ischemia and hypoxia. It is commonly seen in areas such as the knee, which has no muscle wrapping or a thin muscle layer.

[0004] When the protective knee protects the knee area of the patient, most of them are to put the knee sleeve on the knee area of the patient. However, this nesting method can easily cause abrasion and injury to the knee area of the patient, and the knee sleeve cannot be stably sleeved on the knee area of the patient, reducing the practicality of the protective knee.

[0005] In order to overcome the above-mentioned defects, the prior art 1 (Chinese patent with application number CN201320875983.4 and application date of December 30, 2013) a kind of medical pressure relief knee pad, according to the thickness of leg adjusts the position of sponge pad, satisfy patient various lying position knee pressure relief prevent pressure sore needs, while be favorable to patient lying position leg activity, and nursing personnel is convenient, time-saving and labor-saving when assisting patient to turn over operation;

[0006] Although the prior art can achieve quick installation and positioning of the protective knee, avoid abrasion and injury to the knee area of the patient, but after long-term use of the sponge pad, the pus water flowing out of the knee wound surface can contaminate the sponge pad, and the sponge pad needs to be regularly disassembled and replaced to avoid contamination of the sponge pad in the later period.

[0031] The technical solutions in the embodiments of the utility model will be apparently and completely described below with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of protection of the utility model.

[0032] The utility model provides the following technical scheme:

[0033] Embodiment one, to solve the problem that existing knee pad 1 is easy to cause abrasion injury to the knee part of patient when installing, and inconvenient to freely adjust the tightness of knee pad 1, discloses:

[0034] Knee pad 1 and sponge pad 2, wherein the sponge pad 2 is attached to the inner side of knee pad 1, and knee pad 1 and sponge pad 2 are both circular arc shape;

[0035] Further comprising: the right side of knee pad 1 is provided with adjusting buckle belt 3, the left side of knee pad 1 is provided with perforation 4, the inside of perforation 4 is connected with adjusting buckle belt 3 in penetration, and the outside of adjusting buckle belt 3 extends to the outside of the left end of knee pad 1 in penetration.

[0036] The inside of the left side of knee pad 1 is provided with limiting block 9, and the limiting block 9 is circular arc shape, and the outside of limiting block 9 is sequentially connected with a row of limiting slots 10, and the row of limiting slots 10 is equidistantly provided in the inside of adjusting buckle belt 3, the inside of the left side of knee pad 1 is provided with extrusion spring 11, and the outside end of extrusion spring 11 is connected with limiting block 9.

[0037] The inner slot of the limiting block 9 is provided with a torsion spring 12, and the inner side of the torsion spring 12 is wound and connected with a rotating rod 5, and the rotating rod 5 is rotatably installed in the inner side of the knee pad 1, and the outer end of the rotating rod 5 extends to the outer side of the left end of the knee pad 1.

[0038] As shown in Figures 1-7 When the knee pad 1 is needed to protect the knee wound of the patient from pressure sores, the knee pad 1 is attached to the wound, and then the adjusting buckle 3 is wound around the knee and extended to the outer side of the knee pad 1 through the perforation 4. At this time, the extrusion spring 11 will pop out the limiting block 9 into a row of limiting grooves 10 on the inner side of the adjusting buckle 3 by its own elastic force. At this time, the adjusting buckle 3 can be limited and positioned, avoiding the loosening and falling of the installed knee pad 1 during use, and improving the protection stability of the knee pad 1.

[0039] When the tightness of the knee pad 1 needs to be adjusted or the knee pad 1 needs to be disassembled, the limiting block 9 is rotated by manually rotating the rotating rod 5, so that the limiting block 9 is separated from the limiting groove 10. At this time, the adjusting buckle 3 can be extracted and reset, which is convenient for disassembling and replacing the knee pad 1, and also convenient for freely adjusting the tightness of the knee pad 1, which is more time-saving and labor-saving.

[0040] In the second embodiment, the sponge pad 2 can be quickly disassembled and replaced, avoiding the pollution of the sponge pad 2 caused by the pus flowing out of the knee wound surface.

[0043] As shown in Figures 1-4 When the sponge pad 2 is used for a long time, the liquid flowing out of the wound will easily soak into the sponge pad 2, and the sponge pad 2 needs to be disassembled and replaced regularly. At this time, the sponge pad 2 is manually torn off, so that the first magic tape 7 is separated from the second magic tape 8. At this time, the sponge pad 2 can be quickly disassembled, and the new sponge pad 2 is pasted on the inner side of the knee pad 1 through the first magic tape 7 and the second magic tape 8. At this time, the sponge pad 2 can be quickly disassembled and replaced, avoiding the pollution of the sponge pad 2 caused by the thick water flowing out of the knee wound surface.
