Description

Technical Field

[0001] The utility model belongs to the technical field of leg pads, and particularly relates to a leg pad for clinical nursing. Background Art

[0002] In clinical nursing work, leg pads are an indispensable auxiliary device. It is mainly used to provide support and elevation for the patient's legs to promote blood circulation, reduce leg swelling, relieve pain, and prevent pressure sores.

[0003] In clinical nursing, the conditions and needs of different patients vary. For some patients who need specific height support for the lower legs, the existing leg pads are difficult to meet the requirements. For example, for patients with lower limb edema, varicose veins, etc., appropriately elevating the lower legs can promote blood return and reduce swelling and pain. However, the existing leg pads cannot be flexibly adjusted to the appropriate height, limiting their therapeutic assistance effect in these situations. In some cases where long-term bedridden care is required, the heat dissipation problem in the lower leg area is more prominent. If the leg pad cannot effectively dissipate the heat generated by the lower legs, it may cause the patient's legs to feel stuffy and sweaty, which not only affects the patient's comfort but also increases the risk of skin problems such as eczema and pressure sores.

[0004] In response to the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model

[0005] In response to the problems in the related art, the utility model proposes a leg pad for clinical nursing to overcome the above-mentioned technical problems existing in the existing related art.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a leg pad for clinical nursing, including a housing. One end of the housing is provided with a wind power assembly. An elevating mechanism is arranged inside the housing. A lower leg pad is arranged at the top of the elevating mechanism. The lower leg pad is slidably installed between the housing. One end of the lower leg pad is rotatably installed with an upper leg pad. The upper leg pad is inclined. Two limiting plates are symmetrically and fixedly installed at one end of the housing close to the upper leg pad. The upper leg pad is clamped in the two limiting plates. A switch is fixedly installed at one end of the housing.

[0008] Further, an air inlet is opened inside the housing. The wind power assembly includes a driving motor. The driving motor is located inside the air inlet and fixedly installed with the housing.

[0009] Further, an output shaft is fixedly installed at the output end of the drive motor, and a rotating blade is fixedly installed at the other end of the output shaft and located in the inner cavity of the housing.

[0010] Further, the lifting mechanism includes a bearing plate fixedly installed in the inner cavity of the housing. A power motor is fixedly installed at the bottom of the bearing plate, and a power shaft is fixedly installed at the output end of the power motor.

[0011] Further, the power shaft penetrates through the bearing plate and extends above the bearing plate. A first synchronous pulley is fixedly installed at the top of the power shaft. A synchronous belt is rotatably installed on the outer wall of the first synchronous pulley, and the other end of the synchronous belt is rotatably installed with a second synchronous pulley.

[0012] Further, the second synchronous pulley is rotatably installed on the top of the bearing plate. A threaded rod is threadedly installed on the central axis of the second synchronous pulley. A pulling plate is rotatably installed at the top of the threaded rod. The pulling plate is fixedly installed at the bottom of the calf cushion. A plurality of sliding rods are fixedly installed at the bottom of the pulling plate. The plurality of sliding rods are slidably installed with the bearing plate. The other ends of the four sliding rods are fixedly installed with a fixing plate below the bearing plate.

[0013] Further, a plurality of ventilation holes are formed inside the calf cushion. A moving plate is fixedly installed at one end of the calf cushion. The moving plate is slidably installed with the housing to ensure the tightness between the housing and the calf cushion during the movement of the calf cushion, so that the wind blows out from the plurality of ventilation holes.

[0014] The utility model has the following beneficial effects:

[0015] 1. By the operation of the lifting mechanism, the lifting mechanism drives the calf cushion to move, enabling the calf cushion to slide up and down relative to the housing, and the height of the calf cushion can be flexibly adjusted according to the conditions and needs of different patients to meet the treatment assistance requirements.

[0016] 2. When a patient is in long-term bed care, the heat dissipation requirement of the calf part increases. The wind power component starts to work, causing the air outside the housing to generate an air flow. This air flow flows along the inside of the housing and blows towards the calf cushion, and then blows from the calf cushion to the patient's calf to dissipate heat from the patient's calf, avoiding skin problems such as leg stuffiness, sweating, and possible eczema and pressure sores caused thereby.

[0017] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. Description of the Drawings

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, rather than all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the utility model.

[0029] In the description of the present utility model, it should be understood that terms such as "opening", "upper", "lower", "top", "middle", "inner", etc. indicating orientation or positional relationship are only for facilitating the description of the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the utility model.

[0030] Please refer to Figures 1-7 As shown, the present utility model is a leg support for clinical nursing, including a housing 1. One end of the housing 1 is provided with a wind power assembly 2. An elevating mechanism 3 is arranged inside the housing 1. A calf cushion 4 is arranged at the top of the elevating mechanism 3. The calf cushion 4 is slidably installed between the calf cushion 4 and the housing 1. One end of the calf cushion 4 is rotatably installed with a thigh cushion 5. The thigh cushion 5 is inclined. Two limiting plates 6 are symmetrically and fixedly installed at one end of the housing 1 close to the thigh cushion 5. The thigh cushion 5 is clamped in the two limiting plates 6. A switch 7 is fixedly installed at one end of the housing 1.

[0031] First of all, the housing 1 serves as the main structure of the entire leg support, providing an installation and protection space for the internal components. The switch 7 is fixedly installed at one end of the housing 1 and is used to control the start and stop of the elevating mechanism 3. The calf cushion 4 is used to support the calf part of the patient. The thigh cushion 5 is rotatably installed at one end of the calf cushion 4 and is inclined, which can better fit the natural angle of the patient's thigh and provide comfortable support for the thigh. The two limiting plates 6 are symmetrically fixed at one end of the housing 1 close to the thigh cushion 5. The thigh cushion 5 is clamped in the limiting plates 6 to ensure that the thigh cushion 5 is stable in position during use and will not move randomly, thereby providing stable support for the patient's leg. The elevating mechanism 3 is located inside the housing 1, and its top is connected to the calf cushion 4. When it is necessary to adjust the height of the calf for specific patients (such as patients with lower limb edema and varicose veins) to promote blood return, reduce swelling and pain, the elevating mechanism 3 starts to work. Subsequently, the elevating mechanism 3 will drive the calf cushion 4 to move, so that the calf cushion 4 slides up and down relative to the housing 1. In this way, according to the conditions and needs of different patients, the calf cushion 4 can be flexibly adjusted to a suitable height to meet the requirements of treatment assistance. In addition, when adjusting the height of the calf cushion 4, it is necessary to first disengage the thigh cushion 5 from the limiting plate 6 by hand to ensure the normal up and down sliding of the calf cushion 4. After adjusting the position of the calf cushion 4, then clamp the thigh cushion 5 in the limiting plate 6 by hand. The sliding of the calf cushion 4 in the housing 1 will not exceed the height of the housing 1 itself, avoiding the separation between the calf cushion 4 and the housing 1, and the height of the housing 1 can be determined according to specific needs.

[0032] Secondly, the wind power component 2 at one end of the outer shell 1 is mainly used to solve the heat dissipation problem of the patient's calf. When the patient is in long-term bed care and the heat dissipation requirement of the calf is prominent, the wind power component 2 starts to generate air flow. The wind power component 2 blows the outside air into the interior of the outer shell 1 and towards the calf cushion 4, and then blows towards the calf through the calf cushion 4. Since the calf cushion 4 is slidably installed on the outer shell 1, the connection between the two is designed to ensure a certain tightness, enabling the air flow to blow out smoothly from the calf cushion 4.

[0033] Finally, through the operation of the lifting mechanism 3, the lifting mechanism 3 drives the calf cushion 4 to move, enabling the calf cushion 4 to slide up and down relative to the outer shell 1, and the height of the calf cushion 4 can be flexibly adjusted according to the conditions and needs of different patients to meet the requirements of treatment assistance.

[0034] When the patient is in long-term bed care, the heat dissipation requirement of the calf increases, and the wind power component 2 starts to work, causing the air outside the outer shell 1 to generate an air flow. This air flow flows along the interior of the outer shell 1 and blows towards the calf cushion 4, and then blows towards the patient's calf from the calf cushion 4, dissipating heat from the patient's calf and avoiding skin problems such as leg stuffiness, sweating, and possible eczema and pressure sores caused thereby.

[0035] In one embodiment, for the above-mentioned outer shell 1, an air inlet 101 is provided inside the outer shell 1. The wind power component 2 includes a driving motor 201, and the driving motor 201 is located in the air inlet 101 and fixedly installed on the outer shell 1.

[0036] An output shaft 202 is fixedly installed at the output end of the driving motor 201, and a rotating blade 203 is fixedly installed at the other end of the output shaft 202 and located in the inner cavity of the outer shell 1.

[0037] A plurality of ventilation holes 401 are provided inside the calf cushion 4. A moving plate 402 is fixedly installed at one end of the calf cushion 4, and the moving plate 402 is slidably installed on the outer shell 1 to ensure the tightness between the outer shell 1 and the calf cushion 4 during the movement of the calf cushion 4, so that the wind blows out from the plurality of ventilation holes 401.

[0038] When it is necessary to dissipate heat from the patient's calf, the drive motor 201 is started. When the drive motor 201 works, its output end drives the output shaft 202 to rotate. The rotating blade 203 located at the other end of the output shaft 202 in the inner cavity of the housing 1 also rotates accordingly. The rotation of the rotating blade 203 generates an air flow. The air flow enters the interior of the housing from the air inlet 101. A plurality of ventilation holes 401 are provided inside the calf pad 4, and a moving plate 402 at one end of the calf pad 4 is slidably installed with the housing 1, ensuring the tightness between the housing 1 and the calf pad 4 during the movement. In this way, the air flow generated by the rotating blade 203 can smoothly reach the calf pad 4 through the interior space of the housing 1 and blow out from the plurality of ventilation holes 401. The air flow directly acts on the patient's calf placed on the calf pad 4, accelerating the air flow around the calf, taking away heat, realizing the heat dissipation of the calf, and avoiding skin problems such as stuffiness, sweating, and possible eczema and pressure sores on the patient's legs.

[0039] In one embodiment, for the above-mentioned lifting mechanism 3, the lifting mechanism 3 includes a bearing plate 301, the bearing plate 301 is fixedly installed in the inner cavity of the housing 1, a power motor 302 is fixedly installed at the bottom of the bearing plate 301, and a power shaft 303 is fixedly installed at the output end of the power motor 302.

[0040] The power shaft 303 passes through the bearing plate 301 and extends above the bearing plate 301. A first synchronous pulley 304 is fixedly installed at the top of the power shaft 303. A synchronous belt 305 is rotatably installed on the outer wall of the first synchronous pulley 304, and the other end of the synchronous belt 305 is rotatably installed with a second synchronous pulley 306.

[0041] The second synchronous pulley 306 is rotatably installed on the top of the bearing plate 301. A threaded rod 307 is threadedly installed on the central axis of the second synchronous pulley 306. A pulling plate 308 is rotatably installed at the top of the threaded rod 307. The pulling plate 308 is fixedly installed at the bottom of the calf pad 4. A plurality of sliding rods 309 are fixedly installed at the bottom of the pulling plate 308. The plurality of sliding rods 309 are slidably installed with the bearing plate 301. The other ends of the four sliding rods 309 and below the bearing plate 301 are fixedly installed with a fixing plate 310.

[0042] First, the bearing plate 301 is fixedly installed in the inner cavity of the housing 1. When it is necessary to adjust the height of the calf cushion 4, press the switch 7. Subsequently, the switch 7 will send an instruction to start the power motor 302 at the bottom of the bearing plate 301. The output end of the power motor 302 drives the power shaft 303 to rotate. The power shaft 303 passes through the bearing plate 301 and extends upward. The first synchronous pulley 304 fixedly installed at its top rotates together with the power shaft 303. The first synchronous pulley 304 drives the second synchronous pulley 306 to rotate through the synchronous belt 305. The second synchronous pulley 306 is rotatably installed on the top of the bearing plate 301. Since a threaded rod 307 is threadedly installed on the central axis of the second synchronous pulley 306, when the second synchronous pulley 306 rotates, the threaded rod 307 will move in the vertical direction. The top of the threaded rod 307 is rotatably installed with a pulling plate 308, and the pulling plate 308 is fixedly installed at the bottom of the calf cushion 4. Therefore, the up and down movement of the threaded rod 307 will drive the pulling plate 308 to move up and down. A plurality of sliding rods 309 fixedly installed at the bottom of the pulling plate 308 are slidably installed with the bearing plate 301, which play a guiding and stabilizing role when the pulling plate 308 moves. The other ends of the four sliding rods 309 and located below the bearing plate 301 are fixedly installed with a fixing plate 310, which further ensures the stability of the sliding rods 309 and prevents them from slipping off the bearing plate 301;

[0043] In summary, by driving the first synchronous pulley 304, the synchronous belt 305 and the second synchronous pulley 306 to rotate through the power motor 302, the threaded rod 307 is driven to move up and down, so that the pulling plate 308 drives the calf cushion 4 to slide up and down relative to the housing 1, realizing the adjustment of the height of the calf cushion 4 to meet the needs of different patients.
