Dry powder dialysis bottle

Abstract

The invention discloses a dry powder dialysis bottle. The dry powder dialysis bottle comprises a big-end-up conical bottle body, wherein a connecting part is arranged at the upper end of the conical bottle body, an upper cover is arranged on the connecting part, and the upper cover is detachably connected with the connecting part; a discharge inlet is formed in the upper end of the upper cover; a discharge outlet is formed in the lower end of the conical bottle body; a limiting convex ring is arranged at the upper end of the inner wall of the upper cover, the upper end of the connecting part is in contact with the limiting convex ring, and silica gel rings cooperating with the connecting part are arranged on the lower surface of the limiting convex ring; and a filtering membrane is arranged in the limiting convex rings, the filtering membrane is arranged on elastic mounting rings, and the mounting rings are placed in an annular groove formed in the inner walls of the limiting convex rings. According to the scheme, the filtering membrane is arranged on the upper cover, impurities in dialysate can be effectively filtered out, and besides, the upper cover is detachably connected with the conical bottle body. The upper cover extrudes the silica gel rings, so that good sealing performance is ensured, and the situation of powder leakage is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dry powder dialysis bottle. Background technique [0002] Hemodialysis dry powder is suitable for sodium bicarbonate dialysis treatment of patients with acute and chronic renal failure or acute dialyzable poison poisoning. It is a special raw material for preparing hemodialysis solution, which is used to treat renal failure, anuria and electrolyte disturbance caused by drug poisoning. The dry powder dialysis bottle is used to package and store the hemodialysis dry powder. The hemodialysis dry powder is directly put into the bottle after the production is completed. Many dry powders with insufficient particle uniformity and large particles will also be stored in the bottle and cannot be removed, affecting the overall product. the quality of. [0003] In addition, the dry powder dialysis bottle in the prior art needs to be assembled due to the filter mechanism in the mi...

AI Technical Summary

Problems solved by technology

The dry powder dialysis bottle is used to package and store the hemodialysis dry powder. The hemodialysis dry powder is directly put into the bottle after the production is completed. Many dry powders with insufficient particle uniformity and large particles will also be stored in the bottle and cannot be removed, affecting the overall product. the quality of

[0003] In addition, the dry powder dialysis bottle in the prior art needs to be assembled due to the filter mechanism in the middle of the bottle body, so the inlet part needs to be made separately from the bottle body, and then connected by heat welding. Heat welding usually uses the inlet of Industry 4.0 It takes at least 47 seconds for the equipment to process from two separately produced parts entering the machine and then welding to the product exiting the machine, and the highest yield rate can only reach 96%.

Therefore, the dry powder dialysis bottle in the prior art has the problems of high cost, low efficiency and low yield in the production process.

[0004] In the prior art, the filter mechanism in the middle of the dry powder dialysis bottle usually uses a sintered PE plastic filter. This sintered filter controls the filtration accuracy through the sintered plastic particle size, resulting in the inability to accurately control the filtration accuracy. Often As a result, the filtration accuracy cannot meet the requirements of hemodialysis
