Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and specifically relates to a decompression protection structure for heel pressure sores of patients. Background Art

[0002] In the clinical nursing scenario, patients who are bedridden for a long time, in intensive care, or have limited mobility are prone to continuous local tissue compression due to the lack of autonomous movement regulation in the heel area. According to medical research, when the pressure on the skin surface exceeds the normal closing pressure of capillaries, the compressed area will experience ischemia and hypoxia symptoms due to blocked blood circulation, and tissue damage will occur after 6 - 8 hours, resulting in pressure sores.

[0003] Traditional decompression protection structures made of ordinary cotton materials have certain softness but poor elasticity, cannot effectively disperse pressure, and are prone to bacterial growth after absorbing liquid. In addition, most existing protective devices adopt an integral design and need to be completely disassembled during replacement, which not only increases the workload of medical staff, but also frequent operations will interfere with the patient's rest and may even cause secondary injuries due to improper operation, making it difficult to meet the comprehensive requirements of high efficiency, safety, and comfort in clinical nursing. Summary of the Invention

One end of the connecting edge block is movably installed with a front foot protector, one end of the front foot protector is fixedly connected with a fixing edge block, and one end of the fixing edge block is fixedly connected with a limiting rod, and a plurality of limiting rods are provided. The plurality of limiting rods are fitted with the fixing holes; the decompression structure includes a support cushion movably arranged inside the front foot protector, a decompression pad is movably installed inside the support cushion, the bottom of the support cushion is fixedly connected with fixing blocks, and a plurality of groups of fixing blocks are provided. Positioning holes are provided at the bottom ends inside the rear foot protector and the front foot protector, and a plurality of groups of positioning holes are provided. The plurality of groups of fixing blocks are fitted with the positioning holes.

[0006] Preferably, leather ropes are provided on the inner sides of the rear foot protector and the front foot protector, and connecting blocks are provided on the outer periphery of the leather ropes.

[0007] Preferably, a placement groove is provided inside the support cushion, and the decompression pad is fitted with the placement groove.

[0008] Preferably, a pulling piece is fixedly connected to one side of the decompression pad, and the pulling piece is made of glass fiber material.

[0009] Preferably, a pull-out groove is provided on one side of the interior of the rear foot guard and the front foot guard, and the pulling piece is engaged with the pull-out groove.

[0010] Preferably, ventilation grooves are provided inside the rear foot guard and the front foot guard at the top of the positioning hole, and there are two groups of ventilation grooves.

[0011] Preferably, the interior of the pressure relief pad is provided with slots, and there are two groups of slots.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention realizes dynamic and long-lasting pressure relief protection through the innovative combination of a pressure relief pad with a polyurethane foam composite silver ion coating and an EVA foam material support sleeve, coupled with two sets of grooves with preset weak fracture lines inside the pressure relief pad and a traction structure of a glass fiber pulling piece. When the front end of the pressure relief pad contacts the patient's heel and is pressurized, causing wear or contamination of exudate, medical staff can directly tear off the contaminated section along the groove to avoid hand contact with the wound and infection. The contaminated section can be pulled out by axially pulling the pressure relief pad along the pull-out groove by the pulling piece, and the unused rear end can be moved forward in the placement groove of the support sleeve, so that the new pressure relief area is precisely aligned with the pressure area of the heel. The porous structure of the polyurethane foam quickly absorbs exudate through capillary action, the silver ion coating continuously inhibits bacterial growth, and the EVA support sleeve assists in dispersing pressure through elastic deformation. The ventilation grooves inside the foot protector accelerate air circulation, forming a "moisture absorption-antibacterial-pressure relief-breathable" composite protection system, which not only reduces the interference to patients caused by frequent replacement of protective gear, but also extends the single use cycle, thereby improving the efficiency of pressure ulcer prevention and care.

[0014] 2. The present invention realizes the rapid operation and flexible replacement of the protective gear assembly through the interlocking design of the limit rod and the fixing hole made of elastic rubber material, and the detachable connection structure between the fixed block at the bottom of the support sleeve and the positioning hole. During assembly, the fixed edge block of the front foot guard is inserted into the connecting edge block of the rear foot guard through the elastic deformation of the limit rod, forming a stable and detachable splicing structure, which can be disassembled by pulling it in the opposite direction, making it convenient for the protective gear to be sterilized at high temperature or disinfected by ultraviolet light as a whole; when the decompression assembly needs to be replaced, the support sleeve is pulled upward to disengage its fixed block from the positioning hole, and the support sleeve and the decompression pad can be taken out and replaced together. This modular design not only ensures the stability of the splicing of the front foot guard and the rear foot guard, preventing the protective gear from loosening when the patient is active, but also allows the decompression pad to be quickly updated without disassembling the entire protective gear, which reduces the difficulty of operation for medical staff and reduces the irritation to patients caused by frequent care. At the same time, it meets the strict requirements of infection control in the medical environment and achieves a dual improvement in practicality and safety. Brief Description of the Drawings

Detailed Description of the Invention

[0024] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] As shown in Figure 1 to Figure 7 shown:

[0026] Embodiment 1: The present invention provides a decompression protection structure for a patient's heel pressure sore, including a rear foot guard 1, a front foot guard 2, a decompression component, and a splicing component; the splicing component includes a connecting edge block 101 provided at one end of the rear foot guard 1, and a fixing hole 102 is provided inside the connecting edge block 101. There are several fixing holes 102. One end of the connecting edge block 101 is movably installed with a front foot guard 2. One end of the front foot guard 2 is fixedly connected with a fixing edge block 201. One end of the fixing edge block 201 is fixedly connected with a limiting rod 202. There are several limiting rods 202, and several limiting rods 202 are fitted with the fixing holes 102; the decompression structure includes a support cushion 6 movably arranged inside the front foot guard 2. A decompression pad 8 is movably installed inside the support cushion 6. The bottom of the support cushion 6 is fixedly connected with a fixing block 601. There are several groups of fixing blocks 601. Positioning holes 5 are provided at the bottom ends inside the rear foot guard 1 and the front foot guard 2. There are several groups of positioning holes 5. Several groups of fixing blocks 601 are fitted with the positioning holes 5. A slot 801 is provided inside the decompression pad 8, and there are two groups of slots 801. One side of the decompression pad 8 is fixedly connected with a pulling piece 3, and the pulling piece 3 is made of fiberglass material.

[0027] The decompression pad 8 is made of a polyurethane foam composite silver ion coating material, combined with the support cushion 6 of EVA foam material, which can not only disperse the heel pressure through elastic deformation, but also absorb exudate by capillary action. The staff wears the device on the patient's foot. Through the segmented use design and the slot 801 of the decompression pad 8, dynamic pressure dispersion and long-term protection are realized. The two slots 801 inside the decompression pad 8 are designed as preset weak fracture lines. The staff can tear off the used and contaminated section along the slot 801 to avoid contacting the wound surface. At the same time, the decompression pad 8 adopts a long strip design that can be axially pulled. When the previous section is compressed, worn, or contaminated with exudate, the medical staff can pull out the used part through the fiberglass pulling piece 3. At the same time, the unused end moves inside the support cushion 6, so that the new decompression area is aligned with the patient's heel. Using the easy-to-tear characteristic of the slot 801 to quickly remove the contaminated section, combined with the traction function of the pulling piece 3 to realize the axial displacement of the decompression pad 8, so as to continuously provide a new buffer area for the heel without disassembling the protective device, which not only reduces the interference to the patient caused by frequent replacement;

[0028] First, the staff aligns the fixed edge block 201 of the front foot guard 2 with the connecting edge block 101 of the rear foot guard 1, inserts the limit rod 202 into the fixing hole 102, and completes the splicing of the front foot guard 2 and the rear foot guard 1. The limit rod 202 is made of elastic rubber and can be stably inserted into the fixing hole 102 to ensure the stability of the splicing of the front foot guard 2 and the rear foot guard 1. Conversely, pulling the front foot guard 2 and the rear foot guard 1 in opposite directions to separate the limit rod 202 from the fixing hole 102 can quickly disassemble the front foot guard 2 and the rear foot guard 1. The staff pulls up the support cushion 6 so that the fixing block 601 at its bottom is separated from the positioning hole 5 at the inner bottom end of the rear foot guard 1 and the front foot guard 2, and then the entire support cushion 6 and the decompression pad 8 can be replaced, which is convenient for the staff to quickly disassemble and replace the decompression pad 8 after it is used up. The front foot guard 2 and the rear foot guard 1 are also made of TPU (thermoplastic polyurethane elastomer) material to avoid harm to the patient's feet.

[0029] Embodiment 2: This embodiment is basically the same as the previous one, except that leather ropes 10 are arranged on the inner sides of both the rear foot guard 1 and the front foot guard 2, and connecting blocks 9 are arranged on the outer periphery of the leather ropes 10.

[0030] The leather ropes 10 on the inner sides and the connecting blocks 9 can ensure the tightness of the front foot guard 2 and the rear foot guard 1 and prevent the protective device from falling off.

[0031] Specifically, a placement groove 602 is arranged inside the support cushion 6, and the decompression pad 8 is fitted into the placement groove 602.

[0032] The decompression pad 8 can move inside the placement groove 602 of the support cushion 6.

[0033] Specifically, pull-out grooves 7 are arranged on one side inside both the rear foot guard 1 and the front foot guard 2, and the pulling piece 3 is fitted into the pull-out grooves 7.

[0034] Medical staff can pull out the used part from the pull-out groove 7 through the fiberglass pulling piece 3.

[0035] Specifically, ventilation grooves 4 are arranged inside both the rear foot guard 1 and the front foot guard 2 at the top of the positioning hole 5, and there are two groups of ventilation grooves 4.

[0036] Two groups of ventilation grooves 4 inside the protective device and the antibacterial water-absorbing layer of the decompression pad 8 form a convection channel. When the patient's heel sweats or exudes fluid, the liquid is absorbed by the decompression pad 8 and evaporated through the ventilation grooves 4. At the same time, external air flows in through the ventilation grooves 4 to reduce the humid and hot environment inside the protective device.

[0037] Working principle: A functional synergistic system is formed by the pressure relief pad 8 with a polyurethane foam composite silver ion coating and the support sleeve 6 made of EVA foam material to achieve pressure relief, exudate absorption and infection prevention and control for the patient's heel. The two sets of grooves 801 inside the pressure relief pad 8 are designed as preset weak fracture lines. When the section is worn under pressure or contaminated with exudate, medical staff can directly tear off the contaminated section along the groove 801 to avoid contact with the wound surface; at the same time, the pressure relief pad 8 adopts an axially pullable long strip structure, combined with a pulling piece 3 made of glass fiber material and a pull-out groove 7 inside the foot guard. After tearing off the contaminated section, the unused end can be pulled forward in the placement groove 602 of the support sleeve 6 through the pulling piece 3, so that the new pressure relief area is aligned with the patient's heel, thereby achieving "segmented consumption" dynamic pressure dispersion. The fixed block 601 at the bottom of the support sleeve 6 is engaged with the positioning hole 5 at the bottom end of the rear foot guard 1 and the front foot guard 2 to ensure its stable fixation in the protective gear, and the interlocking structure of the placement groove 602 and the pressure relief pad 8, While assisting in dispersing the pressure, it provides a guide frame for the axial movement of the decompression pad 8. During the splicing process of the front foot guard 2 and the rear foot guard 1, the elastic rubber limit rod 202 on the fixed edge block 201 at one end of the front foot guard 2 can be elastically deformed and inserted into the fixing hole 102 of the connecting edge block 101 of the rear foot guard 1 to form a stable detachable connection. When pulled in the opposite direction, the limit rod 202 is separated from the fixing hole 102 due to elastic reset, thereby realizing rapid disassembly; when the decompression assembly needs to be replaced as a whole, the support sleeve 6 is pulled upward to disengage the fixed block 601 from the positioning hole 5, and the support sleeve 6 and the decompression pad 8 can be disassembled together, ensuring that the long-term protection function of the protective gear is achieved through the antibacterial properties of the material, the porous structure of the polyurethane foam and the buffering performance of the EVA without frequently disturbing the patient.
