Description

Technical Field

[0001] The utility model relates to the technical field of medical care products, in particular to a device for assisting lower limb elevation and transfer. Background Art

[0002] Clinically, during the rehabilitation process of patients with knee ligament injuries or lower limb fractures, fear of pain, worry about re-injury, or the inability of some elderly patients to correctly master the activities and movement of the injured limbs, as well as muscle contraction weakness and paralysis caused by the inhibition of muscle contraction impulses by anesthetic drugs after surgery, often lead to some patients being unable or unwilling to cooperate with limb lifting training, or some patients having difficulty in limb transfer activities.

[0003] Prolonged limb immobilization and lack of active rehabilitation training can lead to a series of complications, such as pressure sores, deep vein thrombosis, muscle atrophy, lack of endurance for limb activities, functional degradation or even loss. Abnormal limb function can cause anxiety, insomnia and depression in patients. In addition to having a greater negative impact on patients, it will also increase the patient's hospitalization costs, as well as the workload of clinical medical staff and the burden on their families. In order to minimize the related complications of patients after lower limb surgery, medical staff and their families must spend more time and energy to help patients passively perform limb function training or body position transfer, which is not only time-consuming and labor-intensive, but also fails to achieve the desired effect.

[0004] Currently, there is no auxiliary device on the market that can allow patients to independently perform limb lifting activity training and limb transfer. Clinical medical staff will provide some ankle pump straps, ordinary bandages or braces to assist patients in the above activities, but these tools cannot fully support the weight of the patient's lower limbs, and the patient experience is poor. If the patient after surgery cannot fully support the limbs, the wound will be pulled and pain will occur, all of which lead to reduced patient compliance.

[0005] In this regard, the inventor of this patent combined clinical experience, thought about the problems encountered in clinical work, read a large amount of scientific research materials and literature, and conducted searches and novelties to gradually conceive and design this application to solve related technical problems.

[0077] The auxiliary lower limb lifting and transfer device 1000 of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0078] Reference Figures 1 to 4 As shown, the auxiliary lower limb lifting and transfer device 1000 provided according to the embodiment of the utility model includes a hanger 10, a pulley assembly 20, a pull rope 30 and a fixed leg support 40 for lifting and fixing the patient's lower limbs;

[0079] Among them, the hanger 10 is adapted to be mounted on a hospital bed; the pulley assembly 20 is fixedly installed on the hanger 10; the fixed leg rest 40 is arranged directly below the pulley; the pull rope 30 passes through the pulley assembly 20, and its first end is connected to the fixed leg rest 40, and a pull ring 301 is provided at the second end.

[0080] Based on the above, it can be clearly seen that when the present application is implemented, it is mainly used as an auxiliary lower limb lifting and transfer device 1000.

[0081] Specifically, when applying the present application, the patient lies flat on the bed to rest, and the present application is installed on the bed, and the pull rope 30 is passed through the pulley assembly 20. The patient places the affected limb of the lower limb on the fixed leg rest 40, and then pulls the pull ring 301 toward the arms or toward the head with the hand, and the affected limb of the lower limb can be lifted upward. When the affected limb of the lower limb is slightly moved sideways, it is easy to move the affected limb of the lower limb.

[0082] The use of the above-mentioned application will obviously have the following technical effects:

[0083] First, compared with the ankle pump straps, ordinary bandages or braces provided on the market to assist patients in independently performing limb lifting activity training and limb transfer related operations, the present application is provided with the pulley assembly 20 to drive the pull rope 30 to slide to pull up the patient's affected lower limb, making the operation more convenient and labor-saving.

[0084] Second, when the present application is convenient and labor-saving to use, the patient is also willing to independently perform the above-mentioned limb raising activity training and limb transfer related operations, which helps the patient to perform limb functional exercises, can better prevent muscle atrophy and venous thrombosis of the affected lower limbs, can activate the contraction impulse of the quadriceps muscles, and promote rapid recovery of the affected lower limbs. At the same time, it also helps the patient to quickly transfer the affected lower limbs and transfer the body position, making the present application comprehensive in function and very flexible to use.

[0085] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good use effect.

[0086] Furthermore, in the specific implementation, Figure 1 and Figure 2 As shown, according to one embodiment of the present utility model, the hanging frame 10 includes a bed fixing frame 101 and a crossbar 102 fixedly mounted on the upper part of the bed fixing frame 101 along the left-right direction and located above the bed;

[0087] Among them, the pulley assembly 20 includes two connecting columns 201 vertically fixed in parallel at the bottom of the cross bar 102 and a rotating wheel 202 rotatably connected between the lower parts of the two connecting columns 201; a pulling gap is formed between the inner walls of the two connecting columns 201 and the upper part of the rotating wheel 202; the pull rope 30 passes through the pulling gap.

[0088] In this way, the hanger 10 of the present application is adapted to be installed on a hospital bed to erect the crossbar 102 above the bed, so as to facilitate the hoisting of the pulley assembly 20 to facilitate the pulling rope 30 to pass through its pulling gap.

[0089] Preferably, in this technical solution, continue to control Figure 1 and Figure 2 As shown, according to one embodiment of the present utility model, a plurality of pulley assemblies 20 are provided, and the plurality of pulley assemblies 20 are evenly fixed at the bottom of the cross bar 102 from left to right.

[0090] In this regard, it is clear that for different patients, the affected lower limb may be the left leg or the right leg, so that the position of the lower limb on the bed is different. In this regard, the pull rope 30 can be passed through the pulling gap of the pulley assembly 20 at a suitable position to facilitate pulling up the patient's affected lower limb in the vertical direction, so that the present application has strong adaptability and reliability.

[0091] Furthermore, in the specific implementation, we should refer to Figure 1 and Figure 2As shown, according to one embodiment of the present invention, a plurality of winding grooves 1021 for winding the pull rope 30 are evenly opened from left to right on the outer wall of the cross bar 102 , and the plurality of winding grooves 1021 and the plurality of pulley assemblies 20 are arranged alternately.

[0092] Therefore, it is clear that when the present application is not in use, the pull rope 30 can be partially wound around the desired position in the reeling groove 1021 for fixation to avoid being randomly placed on the bed and causing a mess.

[0093] In addition, in the specific implementation, Figure 1 and Figure 2 As shown, according to one embodiment of the utility model, the bed fixing frame 101 is formed into an inverted F shape, including a bottom fixing plate 1011 arranged along the left-right direction, an upper thin inserting plate 1012 suitable for inserting into the gap between the mattress and the bed board, and a vertical fixing plate 1013 arranged along the vertical direction;

[0094] Among them, the left end of the bottom fixing plate 1011 is connected to the bottom of the vertical fixing plate 1013, and the lower bottom surface of the bottom fixing plate 1011 is provided with a locking bolt 1014 that penetrates to its upper end surface and adapts to the lower bottom surface of the bed board; the left end of the upper thin insert plate 1012 is connected to the middle and lower part of the vertical fixing plate 1013; the left end of the cross bar 102 is fixed to the upper part of the vertical fixing plate 1013.

[0095] Therefore, after the upper thin insert plate 1012 described in the present application is inserted into the appropriate position of the gap between the hospital bed mattress and the bed board, the locking bolt 1014 is manually tightened upwards until its upper end is pressed against the lower bottom surface of the hospital bed board. In this way, the present application can be easily fixed for use. Conversely, when the locking bolt 1014 is loosened downwards until its upper end is downwardly away from the lower bottom surface of the hospital bed board, the thin insert plate can be pulled out from the gap between the hospital bed mattress and the bed board to transport, clean and disinfect the entirety constituted by the present application.

[0096] Furthermore, in the specific implementation, continue to compare Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, the upper portion of the vertical fixing plate 1013 is evenly provided with a plurality of fixing holes 10131 penetrating the left and right end surfaces thereof from top to bottom; the left end of the cross bar 102 can be inserted into any of the fixing holes 10131 to be fixed.

[0097] Preferably, in the technical solution of the present application, the plurality of fixed mounting holes 10131 are preferably screw holes, and the left end of the cross bar 102 is provided with a screw head 1022 adapted to be threaded into any of the fixed mounting holes 10131. In this way, the cross bar 102 can be easily assembled and disassembled, and the height position of the cross bar 102 can be adjusted, so that it has strong flexibility in use and can be fixed to a suitable height according to actual needs.

[0098] Again, in the specific implementation, or reference Figure 1 and Figure 2 As shown, according to an embodiment of the utility model, the upper left end and the lower left end of the upper thin insert plate 1012 are both provided with reinforcing ribs 1015 connected to the middle and lower part of the vertical fixing plate 1013; the bottom fixing plate 1011, the upper thin insert plate 1012, the vertical fixing plate 1013 and the reinforcing ribs 1015 are integrally formed and made of stainless steel.

[0099] Therefore, by providing the reinforcing rib 1015, the connection between the upper thin insert plate 1012 and the vertical fixing plate 1013 is firmly connected, and the connection is not easy to break. In addition, since the bottom fixing plate 1011, the upper thin insert plate 1012, the vertical fixing plate 1013 and the reinforcing rib 1015 described in the present application are integrally formed and made of stainless steel, the whole formed by them is less likely to break at a certain position, thereby extending the service life.

[0100] Furthermore, in a specific implementation, according to an embodiment of the present invention, a plurality of auxiliary buckles 302 are evenly fixed on the outer wall of the pull rope 30 near the second end thereof along the length direction thereof.

[0101] Therefore, when the patient pulls the pull ring 301 toward his arms or toward his head with his hands so that his affected lower limb is intermittently lifted upward or needs to be moved laterally, when the pull ring 301 has reached the limit position and it is inconvenient for the patient to continue holding it, he can hold the auxiliary buckle 302 at the required position and continue to pull the pull rope 30 toward his arms or toward his head to drive the affected lower limb to be lifted or moved laterally. In this way, the pull rope 30 described in the present application is designed more reasonably and is more reliable to use.

[0102] It should be added that in the specific implementation, Figure 2 , Figure 3 and Figure 4 As shown, according to one embodiment of the present utility model, the fixed leg support 40 includes a horizontal L-shaped lightweight support plate 401, a foot restraint sleeve 402 and a leg restraint sleeve 403;

[0103] The foot restraint sleeve 402 is fixedly mounted on the front inner wall of the horizontal L-shaped portable support plate 401 along the up-down direction, and is made of elastic fabric, with both upper and lower ends being open; the leg restraint sleeve 403 is fixedly mounted on the inner bottom surface of the horizontal L-shaped portable support plate 401 along the front-back direction, and is preferably made of cotton fabric, with its front end connected to the lower end of the foot restraint sleeve 402, and a sleeve insertion opening 4031 is opened on its upper part from front to back, and a fastening piece 4032 is provided at the sleeve insertion opening 4031;

[0104] In addition, the inner bottom surface of the horizontal L-shaped portable pallet 401 is evenly provided with a plurality of perspiration ventilation holes 4011 penetrating to the lower bottom surface and connected to the inside of the leg restraint sleeve 403, and the lower bottom surface of the horizontal L-shaped portable pallet 401 is provided with support bars 4012 protruding downward along the front-to-back direction on the left and right sides respectively, and a breathable chamber is formed between the two support bars 4012.

[0105] In this regard, it is clear that:

[0106] First, the transverse L-shaped lightweight support plate 401 described in the present application is obviously made of lightweight material, and preferably made of carbon fiber material. It is light in texture, so that the fixed leg support 40 as a whole will not be too heavy. When it is used to support and fix the patient's affected lower limb, the patient can also easily pull it up together with the patient's affected lower limb, making it effortless to pull it up.

[0107] Second, the purpose of setting up the transverse L-shaped lightweight pallet 401 is that: after the patient's foot is put into the foot restraint sleeve 402, the front inner wall of the transverse L-shaped lightweight pallet 401 can fit well to the patient's foot, so as to better prevent the patient's foot drop; after the patient's affected lower limb is put into the leg restraint sleeve 403, the inner bottom surface of the transverse L-shaped lightweight pallet 401 can better support the patient's affected lower limb; when it is long enough, it can support the affected part of the patient's lower limb, especially the ankle joint and / or knee joint, so as to better protect the relevant injured parts and prevent re-injury.

[0108] Third, when using the present application, the patient's feet are put into the foot restraint sleeves 402, and the patient's lower limbs are put into the leg restraint sleeves 403. When the horizontal L-shaped lightweight pallet 401 can be firmly placed on the hospital bed, the patient's entire affected limb is lifted up with good stability, and the patient's entire lower limb is not easy to tip over.

[0109] Fourthly, the foot restraint sleeve 402 described in the present application is made of elastic fabric, which can elastically restrain the patient's foot.
