Armrest device for preoperative range determination of patient with varicose veins of lower limbs

Abstract

The invention discloses an armrest device for preoperative range determination of a patient with varicose veins of lower limbs. The device comprises a wall top, an H-shaped guide rail is fixedly connected to the lower surface of the wall top through expansion bolts, and an adjustment device is arranged on the upper surface of the bottom of the H-shaped guide rail and comprises driving bearings andvertical rods. The armrest device for preoperative range determination of the patient with varicose veins of lower limbs has the advantages that the positions of horizontal pipes are adjusted, when the device needs to be used, the tops of the vertical rods are inserted in the inner walls of lifting pipes, and the surfaces of the outer sides of clamping plates slide along the inner walls of the lifting pipes until the surfaces of the outer sides of the clamping plates are inserted in the inner walls of clamping grooves in the bottoms; the vertical rods drive the driving bearings at the tops ofU-shaped rods to roll on the surface of the H-shaped guide rail, the distance between the device and the patient is adjusted, and when adjustment is moderate, the vertical rods are jacked upwards, and accordingly each clamping plate is clamped to the clamping groove in the topmost portion; meanwhile, positioning protrusion points are slidingly inserted into positioning grooves, the U-shaped rodsare positioned, and the distance between the armrest device and the patient is adjusted.

Description

technical field [0001] The invention relates to the technical field of venous thrombosis of lower extremities, in particular to an armrest device for preoperative range determination for patients with varicose veins of lower extremities. Background technique [0002] Venous thrombosis of lower extremities is a common peripheral vascular disease, and venous valve insufficiency and concurrent pulmonary embolism caused by venous thrombosis of lower extremities are a major danger to the labor force and life safety of patients. The disease has been paid much attention clinically. Thrombosis of the left lower extremity was much higher than that of the right lower extremity, especially primary iliac-femoral vein thrombosis. Sometimes lower extremity venous thrombosis can also extend centripetally to the inferior vena cava, and even block the renal vein, causing renal failure and threatening life. [0003] At present, before lower extremity venous thrombosis surgery, most doctors ...

AI Technical Summary

Problems solved by technology

[0003] At present, before lower extremity venous thrombosis surgery, most doctors will draw the surgical site in advance on the patient's surgical site. At this time, the patient needs to stand up to paint, but the lower extremity venous thrombosis will make the patient's lower limbs difficult to move. It is difficult for personnel to help, and the patient can only stand by himself. However, the height of ordinary hospital beds is limited, and it is difficult for patients to stand up on the bed. They can only use infusion guide rails and add handrails to the infusion guide rails;

[0004] However, many ordinary infusion guide rails are designed to bear limited gravity and limited by the hardness of the material, so it is difficult to bear the weight of the human body.
