Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a hemodialysis concentrate packaging bag. Background Art

[0002] At present, the existing hemodialysis products on the market are all filled in plastic barrels, which require the use of special hemodialysis machines to complete the configuration process. Moreover, the containers used are all hard plastic barrels, which are easily damaged during transportation. In addition, due to the heavy barrel body, the patient's mobility is affected to a certain extent.

[0003] However, when using dialysis powder or dialysis concentrate, it is still necessary to transfer the dialysis powder or concentrate to a new container and add water for dilution, which causes problems such as easy contamination and inconvenience in use. The new container will also increase the cost.

[0004] Hemodialysis dry powder A is often used in sodium bicarbonate dialysis treatment for patients with acute or chronic renal failure or acute hemodialysis poisoning. It is frequently used in medical hemodialysis treatment. Hemodialysis dry powder A is usually stored in sealed packaging bags.

[0005] Online B dry powder is to put B dry powder in a special container, install it on the dialysis machine and prepare it into saturated sodium bicarbonate solution online. Its advantages are that it is easy to use, no manual liquid preparation is required, it is convenient for transportation and storage, and it also avoids bacterial growth. Since the composition of A dry powder is relatively complex and the dissolution speed of various substances is different, if the same online treatment mode as B dry powder is used, it will not be able to form a concentrated solution with stable composition during the entire treatment process, and the safe treatment of patients cannot be guaranteed.

[0006] CN101181649A discloses that the concentrated liquid is connected to a dialysis machine to prepare the required dialysis liquid, but this is bound to increase the cost of the dialysis machine, and the dialysis machine needs corresponding water addition and stirring. Summary of the invention

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] The present invention provides a hemodialysis concentrate packaging bag and a method for preparing hemodialysis fluid for immediate use. The features and implementation methods of various aspects thereof are described in detail below.

[0031] Design and structure of hemodialysis concentrate packaging bag

[0032] Flexible bag body: The packaging bag is made of flexible material, with an overall cylindrical bottle-shaped design, and a sunken round, conical, or partially sunken 1-5cm cylindrical, conical or square bag at the bottom. When filled with liquid, the packaging bag presents a complete cylindrical bottle shape, like a stable container; when empty, the flexible bag body can be easily folded and curled, which is convenient for storage and transportation, greatly saving space.

[0033] Bag opening and cover: The upper end of the flexible bag body is provided with a bag opening 11, and a cover 2 is installed on the bag opening. The cover is provided with multiple functional openings for operation and auxiliary configuration and use of the dialysate.

[0034] Liquid filling port: The cover 2 is provided with a liquid filling port 12 for directly adding purified water into the bag to dissolve the hemodialysis concentrate in the bag.

[0035] The straw port and straw: The straw port 13 on the lid is connected to a straw 3. The bottom end of the straw extends all the way to the bottom of the bag body to ensure that it can contact the bottom layer of the liquid in the bag, which is convenient for fully mixing and extracting the dialysate.

[0036] Connector and support device: The cover 2 is also provided with a connector, which includes at least three extensions 21, evenly distributed around the cover. The ends of these extensions are provided with rollers 22, which can roll freely on the supporting arms 41 of the supporting device 4 matched therewith. The design of the supporting device matches the shape of the packaging bag. Through the cooperation of the connector and the supporting device, the cover can be fixed and kept in a horizontal state, ensuring the stability of the packaging bag during operation.

[0037] Graduation lines: Graduation lines 16 are clearly marked on the flexible bag body 1 for accurately measuring the volume of the liquid in the bag, so as to facilitate the preparation of the dialysate according to the standard dosage.

[0038] Additional functional component design

[0039] Drug adding port: An additional drug adding port 15 is provided on the cover 2. This design allows additional drugs to be added as needed during the preparation of the dialysate, thereby increasing the flexibility and adaptability of the packaging bag and being able to meet the treatment needs of more special patients.

[0040] Circulation tube and circulation power device: A circulation tube 17 is provided, one end of which is connected to the suction tube port 13, and the other end is connected to the liquid filling port 12. The circulation tube is externally connected to a circulation power device 18, with the help of which the dialysate can circulate in the packaging bag, and through continuous stirring and mixing, the uniformity and stability of the dialysate are further improved, thereby ensuring the quality and therapeutic effect of the dialysate.

[0041] Air filter device: The cover 2 is also provided with an air filter device 14, which can effectively filter impurities and microorganisms in the outside air and prevent external pollutants from entering the packaging bag during operation, thereby ensuring the purity and safety of the dialysate.

[0042] Roller locking piece: The roller 22 is designed with a locking piece. When the position of the packaging bag needs to be fixed, the locking piece can be used to lock the roller to prevent it from rolling, thereby ensuring the stability of the packaging bag in a specific operation link.

[0043] Types of Hemodialysis Concentrates

[0044] The hemodialysis concentrate contained in the hemodialysis concentrate packaging bag is preferably hemodialysis dry powder A powder.

[0045] Method for preparing hemodialysis fluid for immediate use

[0046] Placing the packaging bag: First, place the hemodialysis concentrate packaging bag containing the hemodialysis concentrate steadily on the supporting device 4 that matches the shape of the packaging bag. Through the cooperation of the roller of the connecting piece and the supporting arm, the cover is automatically kept in a horizontal state to ensure the stability of the packaging bag.

[0047] Add water to dissolve: Add pure water through the liquid filling port 12 on the lid of the packaging bag, and add until the required standard amount can be accurately calibrated with the help of the scale line on the bag body. During the water adding process, in order to help the concentrate dissolve quickly and fully, the packaging bag can be vibrated, and the power generated by the vibration can be used to promote the rapid mixing of the concentrate and water, thereby improving the preparation efficiency.

[0048] Circulation stirring: After the dialysate is initially prepared, the circulation tube 17 is installed and connected to the external circulation power device 18. The circulation power device allows the dialysate to circulate in the packaging bag to achieve the purpose of stirring, further fully mix the components in the dialysate, ensure the uniformity of the dialysate, and thus improve the quality and effect of dialysis treatment.

[0049] Adding medicine is optional: In step S2, medicine can be further added through the medicine adding port 15 on the cover according to the patient's specific condition and treatment needs. This step can flexibly adjust the dialysate to be more in line with the patient's individualized treatment plan, thereby improving the pertinence and effectiveness of the treatment.
