Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an infusion set used for hemodialysis. Background Art

[0002] Hemodialysis is a method of treating renal failure. Under normal circumstances, the main function of the kidneys is to filter blood, remove metabolic waste and excess water, and then excrete them from the body in the form of urine. When renal failure occurs, the kidneys completely or almost completely stop working, and external force is needed to help the kidneys work. Hemodialysis is to use a machine to replace the kidneys. During the operation of the hemodialysis machine, in order to prevent the blood from coagulating in the dialysis machine and causing blood clots, etc., it is necessary to continuously input medical sodium citrate solution that has an anticoagulant effect and prevents the formation of blood clots into the dialysis machine.

[0003] The existing installation method of medical sodium citrate solution is that medical staff connect a bag of liquid medicine to the dialysis machine through an infusion tube and hang it on the side wall of the dialysis machine. When the medical staff observes that a bag of liquid medicine has been delivered, they remove the consumed liquid medicine and then manually install the next bag of liquid medicine. This replacement method is more troublesome and requires medical staff to stand by, resulting in a waste of human resources. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings in the prior art, the utility model provides an infusion set for hemodialysis.

[0006] As a preferred technical solution of the utility model, the control component includes a weight sensor, a PLC control module, a connecting plate, a solenoid valve and an infusion tube. The weight sensor is fixedly installed on the upper part of the L-shaped mounting plate, the bottom of the weight sensor is fixedly connected to the top of the mounting frame, the PLC control module is fixedly installed on the lower part of the L-shaped mounting plate, five connecting plates are fixedly connected to the top of the PLC control module at intervals, the front ends of the five connecting plates are fixedly connected to the solenoid valves, the upper ends of the five solenoid valves are connected to the lower ends of the five connecting tubes one by one, and the lower ends of the five solenoid valves are commonly connected to the infusion tube.

[0007] As a preferred technical solution of the utility model, it also includes a connecting sleeve, and the right part of the mounting frame is slidably provided with the connecting sleeve.

[0008] As a preferred technical solution of the utility model, it also includes a limiting block, and a plurality of limiting blocks are arranged at intervals at the lower part of the mounting frame.

[0009] As a preferred technical solution of the utility model, it also includes a reinforcing plate, and three reinforcing plates are fixedly connected to the L-shaped mounting plate in an interval manner.

[0010] As a preferred technical solution of the utility model, it also includes a hook, and four hooks are fixedly connected to the rear side of the L-shaped mounting plate in an interval manner.

[0011] Beneficial effects: 1. By setting up a mounting frame and a control component, multiple bags of liquid medicine can be hung on the mounting frame at one time, and the control component can transport the liquid medicine in multiple bags of liquid medicine to the hemodialysis machine in sequence. In this way, medical staff do not need to stay by for a long time to replace the bagged liquid medicine, thereby reducing the waste of human resources.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.

[0019] Embodiment: An infusion set for hemodialysis, such as Figure 1-Figure 4As shown, it includes an L-shaped mounting plate 1, a mounting frame 2, bagged liquid medicine 001, a connecting pipe 7 and a control component. The upper part of the L-shaped mounting plate 1 is slidably connected to the mounting frame 2, and five bagged liquid medicine 001 are suspended at intervals at the lower part of the mounting frame 2. The lower part of each bagged liquid medicine 001 is connected to the connecting pipe 7 in a snap-on manner. The lower part of the L-shaped mounting plate 1 is provided with a control component for controlling the opening or closing of the connecting pipe 7.

[0020] like Figure 1 and Figure 2 As shown, the control component includes a weight sensor 3, a PLC control module 4, a connecting plate 5, a solenoid valve 6 and an infusion tube 8. The weight sensor 3 is fixedly installed on the upper part of the L-shaped mounting plate 1 by bolts, and the bottom of the weight sensor 3 is fixedly connected to the top of the mounting frame 2 by bolts. The PLC control module 4 is fixedly installed on the lower part of the L-shaped mounting plate 1 by bolts. Five connecting plates 5 are fixedly connected to the top of the PLC control module 4 by bolts at intervals. The front ends of the five connecting plates 5 are welded and fixed with solenoid valves 6. The upper ends of the five solenoid valves 6 are connected to the lower ends of the five connecting tubes 7 in a one-to-one correspondence. The lower ends of the five solenoid valves 6 are commonly connected to the infusion tube 8. The infusion tube 8 includes a connecting block and a hose. A cavity is provided inside the connecting block. Five hoses are connected to the top of the connecting block. The five hoses are respectively connected to the lower ends of the five solenoid valves. A hose is connected to the bottom of the connecting block. The six hoses are all connected to the cavity set inside the connecting block.

[0021] When using the device, first hang five bags of liquid medicine 001 on the lower part of the mounting frame 2, connect five connecting tubes 7 to the five bags of liquid medicine 001 respectively, and then connect the infusion tube 8 to the hemodialysis machine, start the PLC control module 4, and the PLC control module 4 controls the electromagnetic valve 6 located on the far left to open, so that the sodium citrate solution in the bag of liquid medicine 001 located on the far left flows into the infusion tube 8 through the connecting tube 7 and the electromagnetic valve 6 located on the far left, and finally flows into the hemodialysis machine. When the sodium citrate solution in the bag of liquid medicine 001 on the left is consumed, , the weight sensor 3 detects that the total weight of the mounting frame 2 is reduced by the weight of a bag of sodium citrate solution. After receiving this signal, the PLC control module 4 closes the solenoid valve 6 located on the far left, and starts another solenoid valve 6 adjacent thereto, thereby delivering the sodium citrate solution in another bag of medicine solution 001 to the hemodialysis machine. Similarly, the sodium citrate solution in the remaining bag of medicine solution 001 is delivered to the hemodialysis machine in turn. In this way, medical staff do not need to stay by the hemodialysis machine to replace the bag of medicine solution 001, thereby reducing the waste of human resources.

[0022] like Figure 1 and Figure 2 As shown, a connecting sleeve 9 is also included, and the connecting sleeve 9 is slidably provided on the right part of the mounting frame 2.

[0023] When hanging the bagged liquid medicine 001, the connecting sleeve 9 can be removed. After the bagged liquid medicine 001 is installed, the connecting sleeve 9 can be slid and installed on the right part of the mounting frame 2 again. In this way, the right end of the lower part of the mounting frame 2 can be supported to prevent the lower part of the mounting frame 2 from bending and deforming under the gravity of the bagged liquid medicine 001.

[0024] like Figure 3 As shown, it also includes a limiting block 10, and a plurality of limiting blocks 10 are arranged at intervals at the lower part of the mounting frame 2.

[0025] By setting the limit block 10, the bagged liquid medicine 001 can be limited so that the bagged liquid medicine 001 are separated in pairs and do not affect each other. At the same time, it can also prevent the bagged liquid medicine 001 from sliding on the mounting frame 2 and affecting the weight sensor 3.

[0026] like Figure 2 As shown, a reinforcing plate 11 is also included, and three reinforcing plates 11 are welded and fixed to the L-shaped mounting plate 1 at intervals.

[0027] By providing the reinforcing plate 11 , the strength and rigidity of the L-shaped mounting plate 1 can be improved, thereby increasing its stability.

[0028] like Figure 4 As shown, it also includes a hook 12, and four hooks 12 are welded and fixed at intervals on the rear side of the L-shaped mounting plate 1.

[0029] By providing the hook 12, the L-shaped mounting plate 1 is clamped and fixed on the side of the hemodialysis machine, so as to facilitate the use with the hemodialysis machine.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
