Description

Technical Field

[0001] This utility model relates to the technical field of hemodialysis equipment, specifically a multi-formula concentrated solution A connection and supply device. Background Technology

[0002] When performing hemodialysis treatment on patients, medical institutions' blood purification centers use different formulations of concentrated dialysis solution A. There are two methods for supplying concentrated solution A: single-tank supply and centralized supply. Single-tank supply involves transporting individual tanks of concentrated solution A to each dialysis machine, where it is drawn into the machine's suction tubing for dialysis treatment. Centralized supply involves storing concentrated solution A in a central reservoir, which is then piped to each dialysis machine for connection to the suction tubing before dialysis treatment.

[0003] Centralized supply of concentrated solution A is a current and future development trend. Concentrated solution A has different formulations, which are a fundamental element of personalized dialysis treatment prescriptions. Current technologies mostly use centralized supply systems with a single formulation. For treatment using personalized concentrated solution formulations, single-tank supply is still used. The centralized supply system and the dialysis machine are connected using plug-in quick-connect couplings. Using a centralized supply method (single-channel supply) for dialysis cannot achieve personalized dialysis solution formulation; the connection structure between the centralized supply system and the dialysis machine uses plug-in quick-connect couplings, requiring two steps—disconnecting the pipe and connecting the pipe—which is prone to secondary contamination and inconvenient to operate. Utility Model Content

[0004] The purpose of this invention is to provide a multi-formula concentrated A-liquid connection supply device that can switch between single-tank and centralized liquid supply as needed, avoid secondary pollution, and realize individualized dialysis fluid formula supply.

[0005] This utility model is implemented as follows:

[0006] A multi-formula concentrated A solution connection and supply device includes a three-way valve whose first end is controllably connected to a dialysis machine, a suction tube for single-tank liquid supply connected to the second end of the three-way valve, and multiple centralized liquid supply valves connected to the third end of the three-way valve for controllably connecting to multiple centralized liquid supply storage tanks storing concentrated A solutions of different formulations.

[0007] Furthermore, the three-way valve is connected to multiple centralized liquid supply valves via multi-way silicone tubing, and the centralized liquid supply valve is connected to the liquid storage tank via a straight silicone tubing.

[0008] Furthermore, the multi-port silicone tube is covered with a fixing box, which is connected to the third end of the multiple centralized liquid supply valves and the three-way valve respectively.

[0009] Furthermore, protective cotton is provided between the fixing box, the three-way valve, and the multiple centralized liquid supply valves.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention allows for switching between single-tank and centralized fluid supply via a three-way valve, enabling communication between the dialysis machine and the suction tube or storage tank as needed, thus avoiding secondary contamination. Furthermore, by combining multiple centralized fluid supply valves, it controls the supply of concentrated solution A with different formulations to the dialysis machine. The centralized supply of concentrated solution A with different formulations can be activated / switched according to the dialysis prescription requirements, achieving individualized dialysis fluid formulation supply.
