Problems solved by technology

[0003] At present, when performing venography of lower extremities, personnel need to stand on the examination bed in a vertical state first, and then gradually turn the bed into a supine state. The contrast agent is injected, and then when the bed is rotated to 45° and 20°, the contrast agent is injected respectively. The existing detection bed is a rotatable bed board, and the bottom end of the top is fixed with a support board for placing the feet. When a person is lying on the bed, because the bed body is in a tilted state, the person will move down slowly, which will cause the legs to be squeezed and affect the imaging effect. Therefore, we propose a venous thrombosis detection device Lower extremity venography device and method

Embodiment 1

[0030] see Figure 1-Figure 3 , a lower extremity phlebography apparatus for detecting venous thrombus in the figure, including an examination bed 1, with support bars 2 fixed on both sides of the examination bed 1, and two rotating sleeves 3 that are rotatably installed at the tail end of the examination bed 1. On the support mechanism 7 on the examination bed 1 and the linkage mechanism 8 installed on the bottom of the examination bed 1, the adjustment rod 4 is threadedly inserted into the two rotating sleeves 3, and the two ends of the two adjustment rods 4 are rotated and installed with connecting plates 5, and the backing plate 6 is fixed through the connecting plate 5, the supporting mechanism 7 is used for auxiliary support to the patient, and the linkage mechanism 8 is used for adjusting the position of the backing plate 6.

[0031] It should be noted that: in this scheme, the designed support mechanism 7 and linkage mechanism 8 are installed on the examination bed 1, ...

Embodiment 2

[0046] see Figure 7 with Figure 8 , this embodiment is further described for Example 1. The support member 13 in the illustration includes an arc-shaped plate 14, and an adjustment shaft 15 is fixed inside the arc-shaped plate 14, and the adjustment shaft 15 slides through the support rod 12. One side of the adjustment shaft 15 A tooth plate 16 is fixed, and a limiting groove 17 is opened on the other side. A limiting block 18 matching the limiting groove 17 is fixed in the support rod 12, and a rotating shaft 19 is inserted in the supporting rod 12 for rotation, and the rotating shaft The bottom end of 19 is fixed with the adjustment gear 20 meshed with the tooth plate 16, and the top is fixed with a rotary cap 21;

[0047] It should be noted that: the arc-shaped plate 14 can support the patient's armpits. When supporting people of different sizes, considering the improvement of comfort, the design of the sliding plug and the adjustment shaft 15 in the support rod 12 allow...

Embodiment 3

[0049] see Image 6 , this embodiment is further described for other embodiments, the backing plate 6 in the illustration is provided with an adjustment port 34, and a mounting plate 35 is fixed in the adjustment port 34, and a moving rod 36 is slidably inserted into the mounting plate 35, and the moving The outer end of the bar 36 is fixed with an arc-shaped block 37, and the linkage table 22 is fixed with an abutment plate 38 contacting the tail end of the moving bar 36, and the outer side of the moving bar 36 is covered with a push-off spring 39 for pushing the arc-shaped block 37 to move outward. ;

[0050] It is worth noting that: in order to make the contact between the tail end of the moving rod 36 and the abutment plate 38 more stable, the tail end of the moving rod 36 is designed to be fixed with a ball 42 .

[0051] It should be noted that: when the examination bed 1 is in a vertical state, the backing plate 6 is in direct contact with the ground, thereby pressing t...

Abstract

The invention discloses a lower limb vein radiography device and method for venous thrombosis detection, relates to the technical field of vein radiography, and solves the problem that legs are easily squeezed when an existing detection bed inclines. The two rotating sleeves are rotatably installed at the tail end of the examining table, the supporting mechanism is installed on the examining table, the linkage mechanism is installed at the bottom of the examining table, adjusting rods are inserted into the two rotating sleeves in a threaded mode, connecting plates are rotatably installed at the two ends of each adjusting rod, and base plates are fixed through the connecting plates; the supporting mechanism is used for supporting a patient in an auxiliary mode, and the linkage mechanism is used for adjusting the position of the base plate, an existing examination bed is optimized, and the designed supporting mechanism and the linkage mechanism are matched with each other, so that when the examination bed rotates from a vertical rotating state, the patient can be supported in an auxiliary mode; the shank part is prevented from being extruded, and the radiography effect is improved.

Description

technical field [0001] The invention relates to the technical field of venography, in particular to a lower extremity venography device and method for detecting venous thrombus. Background technique [0002] Lower extremity venography is the most common type of extremity venography and is widely used in clinical practice. Angiography is mainly to confirm the presence or absence of deep vein thrombosis, and whether the communicating branch valves of deep veins and superficial veins are sound. [0003] At present, when performing venography of lower extremities, personnel need to stand on the examination bed in a vertical state first, and then gradually turn the bed into a supine state. The contrast agent is injected, and then when the bed is rotated to 45° and 20°, the contrast agent is injected respectively. The existing detection bed is a rotatable bed board, and the bottom end of the top is fixed with a support board for placing the feet. When a person is lying on the be...
