Description

Technical Field

[0001] The utility model relates to the field of medical appliances, and particularly relates to a support frame for examining the limbs of patients. Background Art

[0002] When performing examination work on patients in medical treatment, auxiliary tools are generally used to support the limbs, so that doctors can more conveniently observe the treatment of the limbs or the recovery situation of applying medicine. Therefore, the support frame for patient examination is very common;

[0003] Chinese Patent Authorization Application No.: CN202122662038.3 provides a limb positioning device for radiology examination. In this solution, by screwing the screw until the backing plate touches the operating table and stops, the first fixing plate is fixed on the operating table. The first fixing plate is fixed on the operating table by screwing the bolt into the third threaded hole, and the first fixing plate and the operating table are fixed doubly. Moreover, when the patient's limb needs to be examined at a specific position, this device can also be conveniently disassembled and fixed, saving the physical strength and time of medical staff during the examination process; the medical staff opens the cover plate and places the patient's forearm part into the U-shaped plate of the first fixing plate. The medical staff drives the adjusting rod to rotate by screwing the handle, so that the distance between the first fixing plate and the second fixing plate can be adjusted, enabling this device to be adjusted and fixed according to the limb length of the patient, improving the applicable range of this device. The cover plate and the U-shaped plate are fixed together by the fixing rod inside the first threaded hole, reducing the activity range of the patient's limb. The air bag is inflated by connecting the hose to the air tank, and the patient's limb is lifted by the inflated air bag and contacts the sponge in the cover plate until there is no gap. The patient will only feel a slight lift of the limb during use. The contact between the air bag and the sponge and the limb makes the patient more comfortable and there will be no resistance.

[0004] There are certain drawbacks in the existing support frames for examination. First of all, the structure of the support frame for examination is relatively fixed and cannot adjust the position according to the positions of the limbs of patients with different body shapes. This leads to a low adaptability when the support frame for examination supports the limbs, affecting the use effect of the support frame for examination. For this reason, we propose a support frame for examining the limbs of patients. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present utility model is to provide a support frame for examining the limbs of patients.

[0037] Refer to Figures 1-5 As shown, in a preferred embodiment of the present utility model, a support frame for examining the limbs of a patient includes a body mechanism 1. An adjusting mechanism 2 is installed at the lower end of the body mechanism 1, and a positioning mechanism 3 is installed at the lower end of the adjusting mechanism 2;

[0038] The adjusting mechanism 2 includes a driving member 201. A screw rod 202 is fixedly connected to the transmission end of the driving member 201. Symmetrically distributed guide blocks 203 are sleeved on the outer end of the screw rod 202. A connecting frame 204 is slidably connected to the outside of the guide blocks 203. Lifting rods 205 are hingedly connected to the outer ends of the guide blocks 203, and the other ends of the lifting rods 205 away from the guide blocks 203 are hingedly connected to sliders 206.

[0039] Refer to Figures 1-2 As shown, further, the outer end of the slider 206 is slidably connected to a chute frame 207, and the outer end of the chute frame 207 is slidably connected to a limiting frame 208.

[0040] Refer to Figure 1 As shown, further, the limiting frames 208 are symmetrically distributed, and the tops of the limiting frames 208 are connected to the bottom end of the body mechanism 1.

[0041] By installing the rotation of the screw rod 202 to act on a pair of guide blocks 203 through threads, the guide blocks 203 move in opposite directions to drive the lifting rods 205 to adjust their positions. The chute frame 207 cooperating with the slider 206 can guide the hinged lifting rods 205 during position adjustment, making the lifting adjustment of the lifting rods 205 more stable. The limiting frames 208 can guide the moving and lifting chute frame 207, making the chute frame 207 drive the lower positioning mechanism 3 to move up and down more stably. Thus, the positioning mechanism 3 can support and adjust the positioning of the patient's limbs at different heights, improving the practicality of the support frame in the work of examining the patient's limbs.

[0042] Refer to Figure 1 As shown, further, the body mechanism 1 includes a receiving frame 101. The receiving frames 101 are symmetrically distributed and the receiving frame 101 is of a U-shaped structure.

[0043] Refer to Figure 1 As shown, further, symmetrically distributed mounting plates 102 are fixedly connected to the outer ends of a pair of receiving frames 101, and symmetrically distributed telescopic rods 103 are installed at the inner ends of the receiving frames 101.

[0044] Refer to Figure 1 As shown, further, guide frames 104 are installed at the transmission ends of the telescopic rods 103. A first chute 105 is opened at the outer end of the guide frame 104, and the first chute 105 is located at the inner end of the receiving frame 101.

[0045] By installing the telescopic rod 103, it can drive the horizontal adjustment. While enabling the adjustment mechanism 2 to lift, it can also achieve horizontal adjustment, which is convenient for positioning according to different opening degrees of the patient's limbs. The movable and adjustable guide frame 104 is restricted by the chute 105 to prevent the guide frame 104 from shifting during movement, further improving the stability of the coordinated movement between the structures of the device.

[0046] Refer to Figures 3-5 As shown, further, evenly distributed positioning rings 301 are movably connected to the inner side of the receiving frame 101. The outer ends of the positioning rings 301 are hinge-connected to connecting rings 302. The inner ends of the connecting rings 302 are provided with clamping rods 303. The front ends of the clamping rods 303 are provided with clamping heads 304. The outer ends of the clamping heads 304 are provided with clamping grooves 305, and the clamping grooves 305 are located at the inner ends of the positioning rings 301.

The outer ends of the adjusting members 307 are provided with mounting frames 308, and the mounting frames 308 are located at the bottom ends of the chute frames 207.

[0048] When the device positions the patient's limbs, the connecting ring 302 moves and cooperates with the positioning ring 301 to be fixed outside the limbs. Then, the clamping rod 303 is pressed to make the clamping head 304 clamped at the inner end of the positioning ring 301, making the positioning of the connecting ring 302 and the positioning ring 301 outside the limb more stable and facilitating the support and positioning of the limb.

[0049] Specific implementation process: When the device is used, the driving member 201 is started. The driving member 201 drives the screw rod 202 and the guide block 203 to act in a threaded manner. The guide block 203 moves in the opposite direction to drive the lifting rod 205 to adjust its position. The limiting frame 208 can guide the movable and lifting chute frame 207, so that the positioning mechanism 3 can support and adjust the positioning of the patient's limbs at different heights.

[0050] Then, according to the opening degree of the patient's limb, the telescopic rod 103 is adjusted to be turned on. The telescopic rod 103 can drive the guide frame 104 to perform horizontal adjustment. While enabling the adjustment mechanism 2 to lift, it can also achieve horizontal adjustment, which is convenient for positioning according to different opening degrees of the patient's limbs.

[0051] Finally, the adjusting member 307 is composed of a motor and a lead screw, which can drive the connecting ring 302 and the positioning ring 301 to be conveniently adjusted in position for fixing work according to limbs of different specifications. The connecting ring 302 moves and cooperates with the positioning ring 301 to be fixed outside the limbs. Then, the clamping rod 303 is pressed so that the clamping head 304 is clamped at the inner end of the positioning ring 301, making the connection between the connecting ring 302 and the positioning ring 301 more stable outside the limb, facilitating the support and positioning of the limb.
