Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a user-friendly limb elevation device. Background Technology

[0002] Fracture patients, especially those with lower limb fractures, often require nurses to elevate their limbs or prop them up on temporary supports during dressing changes. Elevation also promotes blood and lymphatic drainage and reduces swelling. Therefore, limb elevation devices are necessary. For example, CN212522285U discloses a limb elevation frame for general surgical care, comprising a base mechanism and a limb frame mechanism. The top of the base mechanism is fixedly connected to the bottom of the adjustment mechanism; the tail of the limb frame mechanism is rotatably connected to the adjustment mechanism. The limb frame mechanism allows for vertical height adjustment, while the rotating column allows for forward and backward adjustment, facilitating adjustments to the patient's joint angles. The moving column allows for horizontal movement, further enhancing joint adjustment and solving the problem of limb movement during clinical care.

[0003] The size of the limb placement frame of this elevation frame is fixed, making it difficult to adjust its length according to the patient's body shape, and it is also inconvenient to limit and fix the patient's limbs, which makes the patient's limb joints prone to bending, which may compress blood vessels and hinder circulation. Therefore, we propose an easy-to-use limb elevation device to solve the above problems. Utility Model Content

A clamping assembly 2 is fixedly connected to one end of the mounting plate 1. One end of a threaded rod 3 is fixedly connected to the top of the mounting plate 1. The threaded rod 3 is slidably sleeved onto one end of a supporting connecting rod 5. Nuts 4 are respectively provided on the top and bottom sides of the supporting connecting rod 5, and the nuts 4 are threadedly sleeved onto the threaded rod 3. One end of a connecting column 6 is fixedly connected to one side of the other end of the supporting connecting rod 5.

The ends of the two sliding rods 10 away from the main lifting plate 8 are respectively fixedly connected to the auxiliary lifting plate 11. One end of the auxiliary lifting plate 11 is respectively fixedly connected to one end of the strap 12. The other end of the strap 12 is glued and fitted with Velcro 13. The Velcro 13 is respectively fixedly connected to the other end of the auxiliary lifting plate 11. The connecting column 6 is movably provided with an unlocking component 9. The unlocking component 9 is inserted and fitted with the positioning hole 81. The positioning hole 81 is recessed in the main lifting plate 8.

[0024] Example 2

[0025] Reference Figure 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the clamping component 2 includes a support plate 21, a threaded knob 22, and a clamping plate 23. The middle of one end of the support plate 21 is fixedly connected to the mounting plate 1. The bottom of the support plate 21 is sleeved with the threaded knob 22 through a threaded structure. The top of the threaded knob 22 is rotatably connected to the clamping plate 23. The clamping plate 23 is movably disposed inside the support plate 21.

[0026] Furthermore, the support plate 21 has a U-shaped structure, and an anti-slip pad is fixedly connected to the end face of the clamping plate 23 away from the threaded knob 22. The anti-slip pad improves the friction at the clamping position.

[0027] The support plate 21 of the clamping assembly 2 is inserted into the bed frame of the medical bed. The bed frame is located between the clamping plate 23 and the support plate 21. Then, the threaded knob 22 is manually tightened, which moves the clamping plate 23 toward the bed frame. The clamping plate 23 cooperates with the support plate 21 to clamp the bed frame, so that the clamping assembly 2 is fixedly installed on the bed frame of the medical bed.

[0028] Specifically, an anti-disengagement cap 31 is fixedly connected to the end of the threaded rod 3 away from the mounting plate 1. The anti-disengagement cap 31 is set to prevent the nut 4 from falling off.

[0029] Specifically, the positioning holes 81 are evenly distributed around the circumference of the connecting plate 7.

[0030] Specifically, the unlocking component 9 includes a slip ring 91, a movable plate 92, a positioning post 93, a spring 94, and a toggle lever 95. There are two slip rings 91, which are slidably connected to the connecting post 6. The two slip rings 91 are fixedly connected to both ends of the movable plate 92. The bottom end of the movable plate 92 is fixedly connected to the positioning post 93, which is inserted into the positioning hole 81. The end of the movable plate 92 away from the connecting plate 7 is fixedly connected to one end of the spring 94. The other end of the spring 94 is fixedly connected to the end of the support rod 5. The end of the movable plate 92 away from the positioning post 93 is fixedly connected to the toggle lever 95. The movable plate 92 has a T-shaped structure.

[0031] The working principle and process are as follows: The support plate 21 of the clamping assembly 2 is inserted into the bed frame of the medical bed. The bed frame is located between the clamping plate 23 and the support plate 21. Then, the threaded knob 22 is manually tightened, which moves the clamping plate 23 toward the bed frame. The clamping plate 23 cooperates with the support plate 21 to clamp the bed frame, so that the clamping assembly 2 is fixedly installed on the bed frame of the medical bed. According to the required elevation height of the patient's limb, the two nuts 4 are manually turned to disengage the two nuts 4 from the clamping limit of the support link 5, so that the support link 5 can change its height position. After the height position is adjusted, the two nuts 4 move toward the support link 5 respectively. After tightening the two nuts 4, the support link 5 is clamped and limited. After the patient's limb is raised, it is placed in the groove on the main lifting plate 8. According to the patient's limb shape, the auxiliary lifting plate 11 is pulled away from the main lifting plate 8. The auxiliary lifting plate 11 cooperates with the main lifting plate 8 to move away from the main lifting plate 8. The elevation plate 8 increases the length of support for the patient's limb. Then, the strap 12, together with the Velcro 13, limits and fixes the patient's limb. When the patient's lower limb is raised, the lower limb will tilt around the femoral head. The unlocking component 9 is manually operated, and the lever 95 is manually moved. The lever 95 moves the fixed movable plate 92 away from the connecting plate 7. At the same time, the movable plate 92 compresses the spring 94. The movable plate 92 also moves the positioning pin 93 out of the positioning hole 81. At this time, the main elevation plate 8 can swing in a circle around the connecting plate 7, thereby changing the tilt angle of the main elevation plate 8. After the adjustment is completed, the lever 95 is released. Under the elastic force of the spring 94, the positioning pin 93 is re-inserted into the positioning hole 81, limiting and fixing the tilt angle of the main elevation plate 8. This makes it convenient to adapt to the tilt angle after the patient's lower limb is raised and avoids bending of the patient's lower limb after being raised.

[0032] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
