Description

Technical Field

[0001] The present invention relates to a medical auxiliary device, and particularly to an upper and lower limb good limb position placement device that is easy to clean and store. Background Art

[0002] The good limb position refers to a therapeutic position designed to prevent or counter the emergence of spastic patterns, protect the movement of large joints such as the shoulder, elbow, hand, hip, knee, and ankle from being restricted, and early induce isolated movement. All kinds of position placements are premised on countering spasticity, making the joints relatively stable after hemiplegia, effectively preventing the typical spastic patterns of the flexor muscles of the upper limb and the extensor muscles of the lower limb. The good limb position is not a functional position, but a temporary position designed from a treatment perspective. Designing the correct good limb position for hemiplegic patients is the key point of early rehabilitation care for hemiplegic patients. The design and placement of the good limb position in the early rehabilitation care of stroke patients are the key points to improve the neurological function, self-care ability in daily life, and quality of life of stroke patients, and have obvious rehabilitation effects on acute stroke patients. If the posture is incorrect, many abnormal patterns can be formed, such as shoulder joint dislocation, shoulder pain, muscle spasm, foot varus and drop, hip joint external rotation, and joint movement limitation and other series of complications. A good limb placement position in bed in the early stage can make the joints relatively stable after hemiplegia, and has a certain role in preventing and relieving spasticity, shoulder subluxation, shoulder pain, shoulder-hand syndrome, pelvic retroversion, hip joint abduction, external rotation, and early inducing isolated movement, etc. It is a very important link in rehabilitation treatment, and at the same time, it is also one of the methods to prevent the emergence of pathological movement patterns in the future; The good limb position placement is a temporary position designed to prevent and counter spastic postures and protect joints and early induce isolated movement. In order to avoid complications such as pressure sores and spasticity, currently, hospitals generally use pillows to lift the lower limbs of patients. However, due to the softness of the pillows, the lifting height is low, and a large number of pillow cores are required, which increases the difficulty of later cleaning. Moreover, the shaping effect of the pillows is poor, and it is difficult to fix the posture of the patients, making the limbs of the patients maintain the good limb position state for a long time. For this reason, we propose an upper and lower limb good limb position placement device that is easy to clean and store. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By respectively providing an adjusting mechanism one, a lumbar pad, an adjusting mechanism two, and a support mechanism on the first mounting plate and the second mounting plate, and providing a lifting mechanism on both the adjusting mechanism one and the adjusting mechanism two, when using the device to assist the patient to maintain a good limb position posture, multiple lifting mechanisms, lumbar pads, and support mechanisms can be used to simultaneously lift and support the shoulder, elbow, wrist, hip, knee, ankle, and toe joints of the patient. It is convenient to use and can be applied to the placement of good limb positions in various postures such as supine position, lateral position, and healthy side lateral position, making the patient feel comfortable and creating conditions for further rehabilitation training.

[0015] 2. By setting the adjusting mechanism one and the adjusting mechanism two to be respectively connected to multiple lifting mechanisms, when using the device, the user can rotate the first worm to drive the support shaft, mounting disc, first fixing plate, fixing disc, and the front lifting mechanism to rotate 180 degrees by using the first worm gear, so that the front lifting mechanism rotates to a suitable side of the first mounting plate, thereby facilitating the adjustment of the position of the front lifting mechanism according to the actual needs of the patient. And when the patient is in the lateral position, the user can control the second motor to work to drive the rear lifting mechanism to rotate by using the third gear, the fourth gear, the sleeve, and the second connecting frame, and at the same time drive the fourth connecting shaft and the first connecting frame to drive the middle lifting mechanism to rotate in the opposite direction of the movement direction of the rear lifting mechanism through the first sprocket and the second sprocket, so that the rear two lifting mechanisms form an angle to adapt to the leg posture of the patient in the lateral position, and the rotation direction of the rear two lifting mechanisms can be adjusted according to the direction of the patient's lateral position, further improving the applicability and functionality of the device.

[0016] 3. In the present invention, a lifting plate and a silica gel strip are arranged inside the first protective pad of the lifting mechanism. When using the lifting mechanism to lift and support the limb of a patient, the first motor can be controlled to operate, driving the connecting shaft II, the turntable and the pull rod to rotate through the first gear and the second gear. At this time, the pull rod slides in the connecting groove, and the pull rod drives the fourth fixing plate and the lifting plate to move up and down reciprocally. When the lifting plate moves upward, the top of the first protective pad is extruded by the silica gel strip, so as to press and massage the limb of the patient by the extrusion of the silica gel strip, thereby promoting the blood circulation of the patient's limb, preventing venous thrombosis, and further increasing the functions of the device.

[0017] 4. In the present invention, a leather surface sleeve is sleeved outside the first protective pad, and an elastic sleeve is arranged at the bottom end of the leather surface sleeve, so that the leather surface sleeve is fixed on the first protective pad by the elastic sleeve. During the use of the device, the user can remove the leather surface sleeve from the first protective pad to wipe and clean the leather surface sleeve, thereby ensuring the cleanliness during the use of the device, further improving the convenience of cleaning the device. At the same time, by setting the insertion plate and the slot to connect the first mounting plate and the second mounting plate, when the device is not in use, the user can pull the limiting rod to the right so that the limiting rod disengages from the limiting hole, and then pull the first mounting plate forward so that the insertion plate disengages from the slot to separate the first mounting plate and the second mounting plate. And the user can rotate the second worm to drive the connecting shaft I and the cam to rotate through the second worm gear, so that the convex end of the cam gradually disengages from the limiting plate. At this time, the pulling force of the first spring pulls the two limiting plates to approach each other, so that the limiting plates gradually disengage from the limiting groove. When the limiting plates disengage from the limiting groove, pull the front lifting mechanism upward so that the front lifting mechanism disengages from the first mounting plate, thereby further reducing the volume of the device, and thus facilitating the user to disassemble, carry and store the device.

[0018] 5. In the present invention, a supporting mechanism is arranged at the rear end of the second mounting plate. When the patient takes the supine position, the ankle can be placed inside the second protective pad to lift and support the ankle joint by the second protective pad, and the sole of the foot is attached to the foot pedal. At this time, the user can rotate the third worm to drive the rotating shaft, the eighth fixing plate and the foot pedal to rotate through the third worm gear, so that the sole of the patient's foot and the calf are kept at a fixed angle by the rotation of the foot pedal, the ankle joint is dorsiflexed to 90 degrees, the toes are upward, preventing foot drop, ankle joint plantar flexion and varus, and at the same time avoiding the occurrence of pressure sores on the heel and outer ankle. And when the supporting mechanism is in use, according to the length of the patient's lower limb, the screw can be rotated to move the screw back and forth along the screw hole to adjust the front and rear positions of the second protective pad, further improving the applicability of the device.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 10 , the present invention provides a technical solution for an upper and lower limb good limb position placement device that is easy to clean and store: including a first mounting plate 1 and a second mounting plate 9. The rear end of the first mounting plate 1 is fixedly connected to the front end of the insertion plate 11. The rear end of the insertion plate 11 is sleeved in the slot 18, and the slot 18 is opened at the front end of the second mounting plate 9. By setting the insertion plate 11 and the slot 18, the first mounting plate 1 and the second mounting plate 9 are connected. When the device is not in use, the user can pull the limit rod 15 to the right so that the limit rod 15 disengages from the limit hole 10, and then pull the first mounting plate 1 forward so that the insertion plate 11 disengages from the slot 18 to separate the first mounting plate 1 and the second mounting plate 9; A first adjusting mechanism 3 is fixedly arranged in the first mounting plate 1, a second adjusting mechanism 8 is fixedly arranged in the second mounting plate 9. The first adjusting mechanism 3 is fixedly connected to one of the lifting mechanisms 4, and the second adjusting mechanism 8 is connected to the other two lifting mechanisms 4. A supporting mechanism 7 is fixedly arranged at the rear end of the second mounting plate 9. By respectively arranging the first adjusting mechanism 3, the lumbar pad 5, the second adjusting mechanism, and the supporting mechanism 7 on the first mounting plate 1 and the second mounting plate 9, and arranging the lifting mechanisms 4 on both the first adjusting mechanism 3 and the second adjusting mechanism 8, when using the device to assist the patient to maintain the good limb position posture, multiple lifting mechanisms 4, the lumbar pad 5, and the supporting mechanism 7 can be used to simultaneously lift and support the shoulder, elbow, wrist, hip, knee, ankle, and toe joints of the patient, which is convenient to use and can be applied to the placement of good limb positions in various postures such as the supine position, the lateral position, and the healthy side lateral position, making the patient feel comfortable and creating conditions for further rehabilitation training.

[0023] The lumbar pad 5 is fixedly arranged at the rear end of the upper surface of the first mounting plate 1. The left end of the insertion plate 11 is provided with a limit hole 10, and the right end of the limit rod 15 is inserted into the limit hole 10. The left end of the limit rod 15 is sleeved in the jack 17 and the second spring 16. The jack 17 is opened on the left side surface of the second mounting plate 9. The two ends of the second spring 16 are respectively fixedly connected to the left end of the limit rod 15 and the left side surface of the second mounting plate 9. By sleeving the second spring 16 on the limit rod 15, the position of the limit rod 15 is restricted by the elasticity of the second spring 16, thereby preventing the limit rod 15 from disengaging from the limit hole 10 and affecting the limiting effect of the limit rod 15 on the insertion plate 11.

[0024] The first adjusting mechanism 3 includes a mounting plate 31. The mounting plate 31 is sleeved in the first through hole 2. The middle part of the mounting plate 31 is fixedly connected to the upper end of a support shaft 33. The bottom end of the support shaft 33 is rotatably connected to the inner bottom surface of the first mounting plate 1 through a rolling bearing. A first worm gear 32 is fixedly arranged in the middle of the support shaft 33. The first worm gear 32 is meshed with a first worm 34. The end optical shaft of the first worm 34 is rotatably connected to the left and right side surfaces of the first mounting plate 1 through rolling bearings. The left end of the first worm 34 is sleeved in the groove 12 and a cross slot is opened on the end face of the left end of the first worm 34. The groove 12 is opened on the left side surface of the first mounting plate 1. When using this device, the position of the front lifting mechanism 4 can be adjusted by using the first adjusting mechanism 3 according to the position of the patient's affected limb. The user can rotate the first worm 34 by using the cross slot at the end of the first worm 34, and drive the support shaft 33, the mounting plate 31, the first fixing plate 37, the fixed disk 35 and the front lifting mechanism 4 to rotate 180 degrees by using the first worm gear 32, so that the front lifting mechanism 4 rotates to a suitable side of the first mounting plate 1, and the angle of the front lifting mechanism 4 can be adjusted by rotating the first worm 34 to keep the patient's arm placed at a corresponding angle.

[0025] One side of the upper surface of the mounting plate 31 is fixedly connected to the bottom end of the first fixing plate 37. The upper end of the first fixing plate 37 is fixedly connected to the upper end of the fixed disk 35. The middle part of the fixed disk 35 is sleeved with a second fixing plate 38.

The four first telescopic rods 311 are divided into two groups, and the opposite ends of the two groups of first telescopic rods 311 are fixedly connected to the opposite ends of two limiting plates 313 respectively. The two limiting plates 313 are respectively sleeved in two limiting slots 39. The two limiting slots 39 are respectively opened at the bottom ends of the front and rear inner side surfaces of the fixed disk 35. The two limiting plates 313 are both wedge-shaped plates. By sleeving a first spring 312 on the first telescopic rod 311 to connect with the limiting plate 313 and the second fixing plate 38, when the convex end of the cam 315 gradually approaches the limiting plate 313 during rotation, at this time, the cam 315 pushes the two limiting plates 313 to move away from each other and move into the limiting slots 39, and the limiting plates 313 stretch the first telescopic rod 311 and the first spring 312 to make the first spring 312 generate a pulling force. Thus, when the convex end of the cam 315 disengages from the limiting plate 313, the pulling force of the first spring 312 is used to pull the two limiting plates 313 to move closer to each other and disengage from the limiting slots 39; A first spring 312 is sleeved on each of the two groups of telescopic rods 311. The two ends of the two first springs 312 are fixedly connected to the front and rear sides of the second fixing plate 38 and the opposite surfaces of the two limiting plates 313 respectively.

When the device is not in use, the user can rotate the second worm 36 to drive the first connecting shaft 316 and the cam 315 to rotate by means of the second worm gear 317, so that the convex end of the cam 315 gradually disengages from the limiting plate 313. At this time, the pulling force of the first spring 312 pulls the two limiting plates 313 to approach each other, so that the limiting plates 313 gradually disengage from the limiting groove 39. After the limiting plate 313 disengages from the limiting groove 39, the front side lifting mechanism 4 is pulled upward, so that the front side lifting mechanism 4 is separated from the first installation plate 1, thereby further reducing the volume of the device, and then facilitating the user to disassemble, carry and store the device; The first connecting shaft 316 is rotatably connected to the second fixing plate 38 through a rolling bearing.

The four corners of the bottom surface of the lifting plate 416 are fixedly connected to the upper ends of the four telescopic rods 44 respectively. The bottom ends of the four telescopic rods 44 are fixedly connected to the upper end of the support plate 41.
