Description

Technical Field

[0001] This invention relates to the field of leg support for turning over mats, specifically a turning over mat with convenient leg support function. Background Technology

[0002] Patients who are bedridden for a long time need to be turned from side to side to avoid pressure sores. In practice, when lying on their side, the legs are pressed together, resulting in poor ventilation. This can easily cause edema in the genitals and skin ulceration. The legs are also prone to ulceration due to poor ventilation and high pressure. Current turning pads only provide back support and do not have the function of leg support to increase ventilation of the genitals. Therefore, how to make the turning pad have the function of upper leg support, reduce the occurrence of pressure sores, and facilitate ventilation of the lower body is an urgent problem for technicians in this field to solve. Summary of the Invention

[0003] The purpose of this invention is to provide a turning mat with convenient leg support function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a turning mat with convenient leg support function, comprising a mat body with a triangular cross-section, and a base plate located at the bottom of the mat body. A support plate located on the rear side of the mat body and pointing upwards is connected to the rear end of the base plate. A support mechanism is connected to the upper right side of the support plate to support the patient's upper leg, reducing pressure sores. The patient can use their own weight to compress the mat body to fix the base plate and prevent tilting. The patient can use their own weight to compress the base plate through the mat body; the heavier the patient, the greater the compression force and the more stable the support mechanism, preventing it from tipping over. The support mechanism supports the upper thigh, reducing pressure on the lower thigh, minimizing pressure sores, and also provides some space for ventilation, making the lower body more comfortable.

[0005] Preferably, the support mechanism includes a reinforcing plate that bends backward from the right end of the support plate to form a perpendicular reinforcing plate. The support plate and the reinforcing plate are at a right angle, which improves stability. A horizontal plate facing to the right is installed at the upper end of the reinforcing plate. A support plate located at the front of the supporting leg is installed at the end of the horizontal plate. The support plate is an arc shape with an upper opening set to the left and right of the center line. The support plate is located in front of the horizontal plate, supporting the knee joint of the supporting leg on the side near the root of the thigh. Of course, it can also support the knee joint on the side near the foot, but the ligaments will be stretched, and the comfort will be reduced.

[0006] Preferably, the horizontal plate and the reinforcing plate are integrally formed and have a rounded transition. The reinforcing plate is made of elastic plastic to generate elastic support force. Of course, stainless steel can also be used, which is elastic. In this way, the upper and lower support height can be varied, making it more comfortable. Alternatively, a thicker rigid stainless steel material can be used to fix the leg support height.

[0007] Preferably, the horizontal plate and the reinforcing plate are hinged together, and the system further includes a telescopic mechanism disposed between the reinforcing plate and the horizontal plate. This telescopic mechanism is connected to an inflation mechanism installed at the front end of the pad on the side in contact with the back. When compressed by the back, the inflation mechanism inflates the telescopic mechanism to push the horizontal plate to flip, changing the support height. The heavier the patient, the greater the compression force on the inflation mechanism, resulting in more gas inside the telescopic mechanism and thus greater support force from the horizontal plate, balancing the weight of the patient's legs. Compared to a fixed connection between the horizontal plate and the reinforcing plate, this hinged connection allows for more flexible support angles. Heavier patients require greater support, while lighter patients require less support, resulting in greater comfort. The support force changes proportionally to the patient's weight.

[0008] Preferably, the telescopic mechanism includes a piston cylinder hinged to the right end of the reinforcing plate and a piston rod inserted into the piston cylinder. The other end of the piston rod is hinged to the lower end of the horizontal plate. A piston chamber is formed between the inner end of the piston rod and the bottom of the inner cavity of the piston cylinder, and the piston chamber is connected to an inflation mechanism via an air pipe. A sealing ring is provided at the inner end of the piston rod to ensure sealing. When the air pipe is inflated, the piston rod extends, pushing the upper horizontal plate to flip upward. When the air pipe is deflated, the piston rod retracts, the horizontal plate flips downward, and the force supporting the load decreases.

[0009] Preferably, the inflation mechanism includes a flat airbag mounted on the pad, and the pad has an installation groove for inserting the airbag, with the rear end of the airbag connected to the trachea. The heavier the patient, the greater the pressure on the pad, and similarly, the greater the pressure on the airbag. Gas will be discharged through the trachea to the piston chamber, resulting in more air inflation into the piston chamber and greater support.

[0010] Preferably, the airbag has a drainage tube groove extending to the right, and the mounting groove extends to the right through the pad. The drainage tube is easy to place, and the opening at the right end of the mounting groove facilitates the extension of the drainage tube, preventing pressure sores. The airbag can also extend to the right through the mounting groove to change the pressure and make adjustments.

[0011] Preferably, the airbag extends upward to form an extension, and the patient can change the pressure in the piston chamber by moving it upward to alter the compression area of ​​the airbag. If the patient wants the horizontal plate to flip upward at a greater angle, they can move it upward to press down a larger area of ​​the extension, thereby increasing the pressure. If the extension is exposed, it will expand towards the patient, reducing the pressure.

[0012] Preferably, the tray is provided with a breathable fleece layer to increase toughness and comfort, and also to make it more breathable.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The patient lies on their side on the mat. Their own weight compresses the mat and the bottom board, while the support board supports the upper leg. The patient's own weight ensures the stability of the support board and prevents it from tilting. At the same time, the heavier the patient, the greater the pressure on the bottom board, preventing the support board from tipping over. The support board reduces the pressure of the upper leg on the lower leg and also creates a gap between the legs for ventilation, preventing pressure sores and promoting ventilation and health of the lower body.

[0015] 2. The piston cylinder, piston rod, trachea, and air bag are designed to adjust the support strength according to the patient's weight. The heavier the patient, the greater the support strength. Compared to fixed-height support, this support that can change with weight allows the patient to move up and down within a certain range, providing elastic support and greater comfort.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] Please see Figures 1 to 2This invention provides a turning pad with convenient leg support: a turning pad with convenient leg support includes a triangular cross-section pad 1, made of compressible sponge material, and a base plate 2 at the bottom of the pad 1. A support plate 3 is connected to the rear end of the base plate 2, extending upwards from the rear side of the pad 1. A support mechanism is connected to the upper right side of the support plate 3 to support the patient's upper leg and reduce pressure sores. The patient can use their own weight to compress the pad 1, thus fixing the base plate 2 and preventing tilting. The patient's weight, through the pad 1, compresses the base plate 2; the heavier the patient, the greater the compression and the more stable the support mechanism, preventing it from tipping over. The support mechanism supports the upper thigh, reducing pressure on the lower thigh, minimizing pressure sores, and also provides some space for ventilation and comfort. A breathable fleece layer is provided on the support plate 6, increasing resilience, comfort, and breathability.

[0027] The support mechanism includes a reinforcing plate 4 formed by bending backward from the right end of the support plate 3. The support plate 3 and the reinforcing plate 4 are at a right angle, which improves stability. A horizontal plate 5 facing to the right is installed at the upper end of the reinforcing plate 4. A support plate 6 located at the front of the supporting leg is installed at the end of the horizontal plate 5. The support plate 6 is an arc shape with an opening at the upper end and is located in front of the horizontal plate 5, supporting the knee joint of the supporting leg near the root of the thigh. Of course, it can also support the knee joint near the foot, but the ligaments will be stretched and the comfort will be reduced. Here, the right end of the horizontal plate 5 can be bent forward into an "L" shape and then connected to the support plate 6 to increase the support distance.

[0028] The horizontal plate 5 and the reinforcing plate 4 are integrally formed and have a rounded transition. The reinforcing plate 4 is made of elastic plastic to generate elastic support. Of course, stainless steel can also be used, which is elastic. In this way, the upper and lower support height can be varied, making it more comfortable. Thicker rigid stainless steel can also be used to fix the leg support height.

[0029] Example 2

[0030] like Figures 3 to 5 As shown, unlike the fixed connection in Embodiment 1, the horizontal plate 5 and the reinforcing plate 4 are hingedly connected. It also includes a telescopic mechanism disposed between the reinforcing plate 4 and the horizontal plate 5. This telescopic mechanism is connected to an inflation mechanism installed on the front end of the pad 1, on the side in contact with the back. When compressed by the back, the inflation mechanism inflates the telescopic mechanism to push the horizontal plate 5 to rotate, changing the support height. The heavier the patient, the greater the compression force on the inflation mechanism, resulting in more gas inside the telescopic mechanism and thus greater support force on the horizontal plate 5, balancing the weight of the patient's legs. Compared to the fixed connection between the horizontal plate 5 and the reinforcing plate 4, this hinged connection allows for more flexible support angles. The heavier the patient, the greater the support force; the lighter the patient, the less support force, resulting in greater comfort. The support force changes proportionally to the patient's weight.

[0031] The telescopic mechanism includes a piston cylinder 7 hinged to the right end of the reinforcing plate 4 and a piston rod 8 inserted into the piston cylinder 7. The other end of the piston rod 8 is hinged to the lower end of the horizontal plate 5. A piston chamber is formed between the inner end of the piston rod 8 and the bottom of the inner cavity of the piston cylinder 7, and the piston chamber is connected to the inflation mechanism through an air pipe 9. A sealing ring is provided at the inner end of the piston rod 8 to ensure airtightness. When the air pipe 9 is inflated, the piston rod 8 extends, pushing the upper horizontal plate 5 to flip upward. When the air pipe 9 is deflated, the piston rod 8 retracts, the horizontal plate 5 flips downward, and the force support decreases.

[0032] The inflation mechanism includes a flat airbag 10 mounted on the pad 1, and the pad 1 has an installation groove for inserting the airbag 10. The rear end of the airbag 10 is connected to the trachea 9. The heavier the patient, the greater the pressure on the pad 1. Similarly, the greater the pressure on the airbag 10, the more gas is discharged into the piston chamber through the trachea 9, resulting in more air inflation into the piston chamber and greater support.

[0033] like Figure 6 As shown, in a preferred embodiment, the airbag 10 has a drainage tube groove 11 extending to the right, and the mounting groove extends to the right through the pad 1. The drainage tube groove 11 facilitates the placement of the drainage tube, and the opening at the right end of the mounting groove facilitates the extension of the drainage tube, preventing pressure sores. The airbag 10 can also extend to the right through the mounting groove to change the pressure and make adjustments.

[0034] Example 3

[0035] like Figure 7 As shown, based on Embodiment 2, in a preferred embodiment, the airbag 10 extends upward to form an extension 12, and the patient can change the pressure in the piston chamber by moving it upward to change the compression area of ​​the airbag 10. If the patient wants the horizontal plate 5 to flip upward at a greater angle, it can move upward to press down a larger area of ​​the extension 12, thereby increasing the pressure. If the extension 12 is exposed, it will expand towards the patient, and the pressure will decrease.

[0036] Working principle: The patient lies on their side on the pad 1. Their own weight compresses the pad 1 and the base plate 2. The support plate 6 supports the upper leg. The patient's own weight ensures the stability of the support plate 6 and prevents it from tilting. At the same time, the heavier the patient, the greater the pressure on the base plate 2, preventing the support plate 6 from tipping over. The support plate 6 reduces the pressure of the upper leg on the lower leg and also creates a gap between the legs for ventilation, preventing pressure sores and promoting ventilation and health of the lower body.

[0037] The piston cylinder 7, piston rod 8, trachea 9, and air bag 10 are designed to adjust the support strength according to the patient's weight. The heavier the patient, the greater the support strength. Compared to fixed-height support, this support that can change with weight allows the patient to move up and down within a certain range, providing elastic support and greater comfort.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
