Sickbed for hemodialysis

Abstract

The invention discloses a sickbed for hemodialysis. The sickbed comprises a bed frame, a supporting mechanism and a lifting mechanism, wherein the supporting mechanism is arranged on the side edge ofthe bed frame; the supporting mechanism can slide and rotate relative to the bed frame; the supporting mechanism comprises a rotating arm, a telescopic arm and a supporting arm; one end of the rotating arm is connected to the side edge of the bed frame; one end of the telescopic arm is rotationally connected with the end, away from the bed frame, of the rotating arm, and the other end of the telescopic arm is rotationally connected with the supporting arm; the lifting mechanism is arranged on the bottom surface of the bed frame; the lifting mechanism comprises an electric air cylinder, a pushrod, a supporting plate and four supporting frames; the electric air cylinder, the push rod and the supporting plate are sequentially connected from bottom to top; and the four supporting frames are arranged at the four corners of the supporting plate respectively. According to the sickbed for hemodialysis, the supporting mechanism is arranged so that the arms of a patient can move, and the situation that the arms of the patient are stiff and uncomfortable due to the fact that the arms are in a posture for a long time during dialysis is avoided; and the height of the bed is adjusted through the lifting mechanism, and the situation that a medical worker bends the waist frequently and inserts a tube, and consequently the waist pain is caused is prevented.

Description

technical field [0001] The invention relates to the technical field of medical beds, in particular to a hemodialysis bed. Background technique [0002] Hemodialysis is required for renal failure, and hemodialysis (HD) is one of the important renal replacement therapies for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers. The blood and the electrolyte solution (dialysate) with a similar concentration to the body are exchanged through diffusion / convection inside and outside the hollow fibers. , remove metabolic waste in the body, maintain electrolyte and acid-base balance; remove excess water in the body at the same time. [0003] For long-term maintenance hemodialysis patients, most of them will establish an arteriovenous fistula in their forearm as a vascular access for dialysis, and the treatment can be performed after each dialysis with a special puncture nee...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a hospital bed for hemodialysis, which solves the technical problems that the patient's forearm is fixed for a long time and cannot be moved, resulting in stiffness, and the low height of the bed causes the medical staff to bend over frequently and feel back pain
