Hemodialysis solution preparation device

Abstract

The invention discloses a hemodialysis solution preparation device. A dry powder bag comprises a bag body, and a discharging connector which is arranged on the bag body and comprises a flaring head fixedly connected with the bag body, a material guide pipe connected with the flaring head, a deformation section formed on the material guide pipe and a stop ring arranged on the deformation section. The preparation device comprises a machine box which is provided with a dry powder conveying device located on the upper portion of the machine box and used for releasing materials in the dry powder bag outwards; a liquid preparation device which is internally provided with liquid for containing dry powder and is used for mixing the dry powder with the liquid in the device in a sealed environment to prepare dialysate; and a quantitative discharging device which is used for controlling the discharging amount of the dry powder and reducing the discharging speed of the dry powder. The dry powder bag is placed in a powder cavity to be communicated with a discharging pipe, and the operation is easy and convenient; and the powder cavity does not need to be supplemented frequently, so that the working efficiency is high, and the possibility that dialysate is polluted is further reduced.

Description

technical field [0001] The invention belongs to the technical field of nephrology, in particular to a device for preparing hemodialysis fluid. Background technique [0002] Hemodialysis is to use the principle of semi-permeable membrane to purify blood, correct water, electrolyte and acid-base balance through diffusion, remove various harmful metabolic wastes and excess electrolytes from the body, and is used in internal medicine for treatment. One of the ways of renal replacement therapy in patients with acute and chronic renal failure. During hemodialysis, dialysate is used to exchange substances with human blood to achieve purification of human blood. [0003] Chinese patent CN104120882B discloses a "stirring device for preparing dialysate", which includes a stirrer, a barrel body and a barrel cover, the agitator enters the barrel body through the barrel cover, the bottom of the barrel body is arc-shaped, and the agitator is provided with Blade; when adding dry powder, ...

Problems solved by technology

[0003] Chinese patent CN104120882B discloses a "stirring device for preparing dialysate", which includes a stirrer, a barrel body and a barrel cover, the stirrer passes through the barrel cover and enters the barrel body, the bottom of the barrel body is arc-shaped, and the stirrer is provided with Blades; when adding dry powder, it needs to be manually scooped into the mixing chamber to control the concentration of the dialysate, the operation is complicated and the control accuracy is low

Secondly, the operation of manual scooping is time-consuming and laborious, and the work efficiency is low
