Description

Technical Field

[0001] The utility model relates to the technical field of nursing frames, in particular to a blood purification nursing frame for a hemodialysis room. Background Art

[0002] Hemodialysis is a renal replacement therapy for patients with acute and chronic renal failure. It uses diffusion, ultrafiltration, adsorption, and convection to exchange substances, remove metabolic waste from the body, and maintain electrolyte and acid-base balance. During hemodialysis, a support frame is often required to support the patient's arm. However, existing support frames are mostly designed for mobility, but in practice, they lack stability and can be easily displaced by impacts and other factors.

[0003] The publication number CN216258032U retrieved after searching disclosed a blood purification nursing rack for a hemodialysis room. By setting a mobile nursing box, a mobile pulley, a fixed plate, a threaded column, a lifting plate, a support column, a support seat and a drive motor, the nursing rack can be moved to a designated location for use by first starting the drive motor to drive the threaded column to rotate. The rotation of the threaded column drives the four support columns to move downward through the lifting plate, so that the support seat lifts the nursing rack upward, thereby effectively improving the stability of the nursing rack during use. The height of the concave arm placement box can be adjusted by setting an electric push rod.

[0004] In the process of realizing the present utility model, the inventors found that there are at least the following problems in the prior art that have not been solved. During use of the above case, the staff is required to first control the electric push rod to adjust the height of the arm placement box, and then control the drive motor to adjust the stability of the mobile nursing box, which is cumbersome to operate.

[0005] Therefore, we propose a blood purification nursing frame for a hemodialysis room, which can automatically adjust the stability of the nursing box while adjusting the support frame. Utility Model Content
