Dry powder bag and dialysis assisting equipment for kidney internal medicine

Abstract

The invention discloses a dry powder bag and dialysis assisting equipment for kidney internal medicine. The dry powder bag comprises a bag body and a discharging joint which is arranged on the bag body, wherein the discharging joint comprises an expanding head fixedly connected with the bag body, a guide tube which is connected with the expanding head, a deformation section which is formed on theguide tube and an intercepting ring which is arranged on the deformation section. A preparing device comprises a device box and a liquid preparing device; the liquid preparing device comprises an accommodating cavity formed in the lower portion of the device box, a preparing chamber formed in the accommodating cavity and a spinning part which is matched with the preparing chamber; the preparing chamber is internally provided with a stirring device, and the rotating direction of the stirring device is opposite to the spinning direction of the preparing chamber. The dry powder bag can be communicated with a discharging tube by placing the powder bag in the powder cavity, and the operation is convenient; materials do not need to be frequently supplied to the powder cavity, and the working efficiency is high; the stirring device is arranged in the preparing chamber, the turbulence effect of liquid in the preparing chamber is improved, the dry powder dissolution rate is high, and the concentration control over dialysate is precise.

Description

technical field [0001] The invention belongs to the technical field of nephrology, and in particular relates to a dry powder bag and dialysis auxiliary equipment for nephrology. Background technique [0002] Hemodialysis is to use the principle of semi-permeable membrane to remove various harmful and redundant metabolic wastes and excess electrolytes from the body through diffusion to achieve the purpose of purifying blood, correcting water-electrolyte and acid-base balance. It is used in internal medicine to treat One of the ways of renal replacement therapy for patients with acute and chronic renal failure. During hemodialysis, dialysate is used to exchange substances with human blood to purify 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 stirrer passes through the barrel cover and enters the barrel body, the bottom of the barrel body is arc-shaped, ...

AI Technical Summary

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 has Blades; when preparing the dialysate, it is only stirred by the agitator in the barrel, the stirring effect is poor, the dissolution rate of the dry powder is low, and the concentration of the prepared dialysate is difficult to reach the specified standard, which affects the dialysis effect

Secondly, the method of manual scooping is used when feeding, which is time-consuming and labor-intensive, and the work efficiency is low
