Description

Technical Field

[0001] This utility model relates to the field of hemodialysis machines, and in particular to a static fluid supply device for hemodialysis machines. Background Technology

[0002] In the use of hemodialysis machines, static fluid supply devices are widely used for fluid supply. A hemodialysis machine consists of two main parts: a blood monitoring and alarm system and a dialysate supply system. The blood monitoring and alarm system includes a blood pump, a heparin pump, arterial and venous pressure monitoring, and air monitoring. The dialysate supply system comprises a temperature control system, a solution preparation system, a degassing system, a conductivity monitoring system, ultrafiltration monitoring, and blood leakage monitoring. Static fluid supply devices are also used in the operation of hemodialysis machines.

[0003] Currently, a static fluid supply device is needed to supply fluid to hemodialysis machines during operation. However, in existing centralized dialysis concentrate supply systems, each hemodialysis machine is equipped with a separate tank of concentrate. During use, the dialysis machine's suction tubing is cut open and connected to the centralized supply line via a Y-shaped tee, or the dialysis machine's suction rod is directly connected to the supply port on the concentrate tank using a plug-and-play method. This cutting of the tubing damages the dialysis machine's suction tubing, resulting in poor performance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a static fluid supply device for hemodialysis machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a static liquid supply device for a hemodialysis machine, comprising a storage tank, a lid fixedly connected to the top of the storage tank, a first liquid level sensor penetrating and disposed at the center of the top of the lid, an alarm fixedly connected to the rear side of the top of the lid, a connecting pipe penetrating and fixedly connected to the bottom of the storage tank, a transition pipe penetrating and fixedly connected to the bottom of the connecting pipe, a uniformly distributed first solenoid valve penetrating and fixedly connected to one side of the outer ring of the transition pipe, a branch pipe penetrating and fixedly connected to the bottom of each of the first solenoid valves, a liquid storage tank penetrating and fixedly connected to the bottom of the branch pipe, and a second liquid level sensor penetrating and disposed on one side of the top of the outer wall of the liquid storage tank.

[0006] As a further description of the above technical solution: A liquid filling tube is connected and fixedly attached to the top right side of the cap.

[0007] As a further description of the above technical solution: A signal receiver is installed on one side of the outer wall of the storage tank, and a control panel is installed at the bottom of the signal receiver.

[0008] As a further description of the above technical solution: A second solenoid valve is fixedly connected through the bottom of the liquid storage tank, and an outlet pipe is fixedly connected through the bottom of the second solenoid valve.

[0009] As a further description of the above technical solution: The bottom of the outlet pipe is connected to a quick-connect fitting.

[0010] This utility model has the following beneficial effects: In this invention, a storage tank, a first liquid level sensor, a second liquid level sensor, a storage container, and a first solenoid valve are used. The first liquid level sensor detects the liquid level in the storage tank. Then, due to gravity, the liquid enters the connecting pipe and flows into the storage container for storage. The second liquid level sensor detects the liquid level in the storage container. After that, the hose is connected to the quick-connect fitting. As used, when the second liquid level sensor detects that the liquid level in the storage container is lower than a preset value, the control panel controls the first solenoid valve to open, automatically feeding the storage container. When the first liquid level sensor detects that the liquid level in the storage tank is lower than the preset value, an alarm sounds to remind the user. It can automatically feed the liquid, is convenient to use, and does not require damage to the suction hose. Attached Figure Description

The liquid in storage tank 1 flows downwards due to gravity and enters the transition pipe 9. Then, the first solenoid valve 11 is opened, and the liquid enters the storage tank 12 for storage. The liquid level inside the storage tank 12 is detected by the second liquid level sensor 16. The bottom of the first solenoid valve 11 is connected to a branch pipe 10, and the bottom of the branch pipe 10 is connected to the storage tank 12. When the second liquid level sensor 16 detects that the liquid level inside is lower than the preset value, the control panel 7 controls the first solenoid valve 11 to open and then deliver liquid into the storage tank 12 until the second liquid level sensor 16 detects that the liquid level has reached the preset value, and then stops adding liquid, realizing automatic feeding. It is convenient to use and does not require repeated plugging and unplugging. The second liquid level sensor 16 is installed on one side of the top of the outer wall of the storage tank 12.

[0016] A liquid filling tube 5 is connected through and fixedly connected to the top right side of the lid 2. A signal receiver 6 is set on one side of the outer wall of the storage tank 1. A control panel 7 is set at the bottom of the signal receiver 6. A second solenoid valve 15 is connected through and fixedly connected to the bottom of the liquid storage tank 12. A liquid outlet tube 14 is connected through and fixedly connected to the bottom of the second solenoid valve 15. The suction tube of the hemodialysis machine is connected to the quick connector 13. When in use, only the second solenoid valve 15 needs to be opened to supply liquid normally. The quick connector 13 is set through and fixedly connected to the bottom of the liquid outlet tube 14.

[0017] Working principle: During use, a certain amount of concentrated liquid is stored in storage tank 1. The first liquid level sensor 3 detects the liquid level. When the first liquid level sensor 3 detects that the internal liquid level is lower than the preset value, the signal receiver 6 receives the signal, and the control panel 7 controls the alarm 4 to sound an alarm, reminding the staff. Then, the liquid in storage tank 1 will flow downwards due to gravity and enter the transition pipe 9. Then, the first solenoid valve 11 is opened, and the liquid enters the storage tank 12 for storage. The second liquid level sensor 16 detects the liquid level inside the storage tank 12. The suction tube of the hemodialysis machine is connected to the quick-connect connector 13. During use, only the second solenoid valve 15 needs to be opened for normal liquid supply. When the second liquid level sensor 16 detects that the internal liquid level is lower than the preset value, the control panel 7 controls the first solenoid valve 11 to open, and then the liquid is delivered into the storage tank 12 until the second liquid level sensor 16 detects that the liquid level has reached the preset value, at which point the addition stops, realizing automatic feeding. It is convenient to use and does not require repeated plugging and unplugging. When not in use, only the second solenoid valve 15 needs to be closed.
