Description

Technical Field

[0001] This utility model relates to the technical field of hemodialysis concentrate preparation, and in particular to a sterile preparation device for hemodialysis concentrate. Background Technology

[0002] In recent years, with the improvement of people's living standards, unhealthy eating habits, and long-term sleep deprivation, the number of patients with uremia has been increasing. Hemodialysis is an important treatment for these patients. During hemodialysis, hemodialysis concentrate is a very important drug solution in dialysis treatment. Since hemodialysis concentrate needs to be injected into the human body, a very strict sterile environment is required during the preparation process. However, in existing hemodialysis concentrate preparation devices, the possibility of bacterial contamination is greatest during the addition stage of the preparation process. Once bacteria are introduced, the hemodialysis concentrate in the entire process will be unusable. To address the above problems, this application provides a sterile preparation device for hemodialysis concentrate. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a sterile preparation device for hemodialysis concentrate, which solves the technical problem of easy bacterial contamination during hemodialysis concentrate preparation and achieves the goal of improving the safety of hemodialysis concentrate preparation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Because hemodialysis concentrate needs to be injected into the body, a very strict sterile environment is required during its preparation. However, existing hemodialysis concentrate preparation devices are most susceptible to bacterial contamination during the addition stage of the concentrate. Once bacteria are introduced, the entire batch of hemodialysis concentrate will be unusable. Please refer to [link / reference]. Figures 1-4 This embodiment provides a sterile preparation device for hemodialysis concentrate, solving the technical problem of easy bacterial contamination during hemodialysis concentrate preparation. The device includes a mixing tank 1 as a supporting base, a sterile feeding mechanism 2 with sterilization function arranged around the mixing tank 1, and a stirring mechanism 3 on the mixing tank 1 to accelerate the mixing of the concentrate. Sterile ingredients are supplied to the mixing tank 1 through the sterile feeding mechanism 2, and the mixing mechanism 3 accelerates the mixing of the ingredients.

[0026] Since hemodialysis concentrate needs to be injected into the human body, a very strict sterile environment is required during the preparation process. However, the existing hemodialysis concentrate preparation device is most likely to introduce bacteria during the addition stage of the preparation process. Once bacteria are introduced, the hemodialysis concentrate will be unusable throughout the entire process. In order to solve this problem, a sterile feeding mechanism 2 is proposed. The aseptic feeding mechanism 2 includes several feeding sealed chambers 21 equidistantly arranged around the mixing tank 1. The ends of the feeding sealed chambers 21 are fitted with folding doors 22 via hinges. Both sides of the inside of the feeding sealed chambers 21 are fixedly connected to baffles 23. A sealing plate 24 is installed on one side of the baffles 23. Both sides of the inside of the feeding sealed chambers 21 are fitted with ultraviolet germicidal lamps 25. A mixing box 26 is placed at the bottom inside the feeding sealed chambers 21. A sealing aluminum film 27 is attached to the top of the mixing box 26. A pressing cylinder 28 is installed on the top of the inside of the feeding sealed chambers 21 via a base. A piercing tube 29 is installed at the extension end of the pressing cylinder 28. A connecting hose 210 is connected to one side of the piercing tube 29. The piercing tube 29 is located directly above the sealing aluminum film 27. The power input terminals of the two ultraviolet germicidal lamps 25 are connected to the power output terminals of an external control terminal.

[0027] During the ingredient preparation process, the aseptic feeding mechanism 2 supplies the ingredients. The operator opens the folding door 22, then removes the sealing plate 24 which is blocked by the partition plate 23, and then places the unopened ingredient box 26 into it. The folding door 22 and the sealing plate 24 are then reset, and the ultraviolet sterilization lamp 25 is turned on to sterilize the ingredient box 26 and the sealing aluminum film 27 on its top. Then, the pressing cylinder 28 is activated, which presses down the piercing tube 29 connected to its extension end to insert into the ingredient box 26. The entire process is completely isolated from the outside environment, ensuring sterility.

[0028] Example 2

[0029] Based on Example 1, which solved the technical problem of easy bacterial contamination during the preparation of hemodialysis concentrate, Example 1 still had the problem of slow mixing speed. Figures 1-4 As shown, the specific implementation process is as follows: In order to accelerate the mixing of the concentrate, the stirring mechanism 3 includes a stirring motor 31 mounted on the top of the stirring tank 1 via a base. The transmission end of the stirring motor 31 extends to the inside of the stirring tank 1 and is equipped with a stirring impeller 32. The bottom end of the stirring tank 1 is connected to a discharge pipe 33. A discharge pump 34 is placed below the stirring tank 1. The inlet end of the discharge pump 34 is connected to the outlet end of the discharge pipe 33. The stirring impeller 32 is located below the inside of the stirring tank 1. Several feed pumps 4 are arranged around the outside of the stirring tank 1. The inlet ends of the feed pumps 4 are respectively connected to the nearby connecting hoses 210. The outlet ends of the feed pumps 4 all extend into the interior of the stirring tank 1 through the top of the stirring tank 1.

[0030] After the aseptic feeding mechanism 2 has completed its operation, the operator starts the feed pump 4 to pump the ingredients into the mixing tank 1. Then, the stirring motor 31 is started, which drives the stirring impeller 32 at its transmission end to rotate, accelerating the mixing of the concentrate.
