Description

Technical Field

[0001] This utility model belongs to the field of hemodialysis technology and relates to an online dialysis dry powder packaging bag. Background Technology

[0002] Hemodialysis utilizes the principle of semipermeable membranes to remove various harmful and excess metabolic waste products and excess electrolytes from the patient's body through diffusion and convection, thereby purifying the blood and correcting water, electrolyte, and acid-base imbalances. Dialysis fluid is a crucial component of hemodialysis, typically composed of hemodialysis concentrate or hemodialysis dry powder mixed with reverse osmosis water at a specific concentration.

[0003] Traditional hemodialysis concentrate is often packaged in 5L plastic containers, which are bulky and have high transportation and storage costs. Hemodialysis dry powder needs to be prepared and used immediately, requiring a dedicated preparation room and ongoing equipment and environmental sterilization and maintenance, increasing the burden and cost of use. Clinically, online-connected B-type dry powder has been implemented, where the dry powder bag is directly connected to the dialysis machine to prepare hemodialysis B-type concentrate. For hemodialysis A-type concentrate, it is usually prepared separately or connected to the dialysis machine using a dedicated packaging bag. While the packaging bag design can replace plastic containers and reduce costs, it often comes into contact with the ground during use, which can cause interface contamination. There is also a risk of the bag tipping over and causing the concentrate to leak when connected to the dialysis machine. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an online dialysis dry powder packaging bag that allows for the simultaneous online use of dry powder A and dry powder B to prepare hemodialysis concentrate A and hemodialysis concentrate B.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] The online dialysis dry powder packaging bag includes a dry powder bag one, a dry powder bag two, and a support plate for mounting the dry powder bag one and the dry powder bag two.

[0007] Dry powder bag one is used for packaging and sealing hemodialysis powder A. When used online, it is suspended on one side of the hemodialysis machine for online preparation of hemodialysis powder A concentrate. Dry powder bag two is used for packaging and sealing hemodialysis powder B. When used online, it is suspended on one side of the hemodialysis machine for online preparation of hemodialysis powder B concentrate. After producing dry powder bags one and two, they are installed on the same support plate, enabling online use of dry powder A and dry powder B to prepare hemodialysis powder A and hemodialysis powder B concentrates.

[0008] In the above-mentioned online dialysis dry powder packaging bag, the support plate is provided with at least one fastener, the upper part of the dry powder bag one is provided with a first mounting hole, the upper part of the dry powder bag two is provided with a second mounting hole, the dry powder bag one is hung on the fastener through the first mounting hole, and the dry powder bag two is hung on the fastener through the second mounting hole.

The first connector has a certain degree of elasticity, and the first mounting hole can move within a certain range during assembly. The first protrusion extends horizontally along the thickness direction of the dry powder bag. In order to better limit the movement, a first buckle is provided on both opposite sides of the first protrusion. After assembly, the two first buckles can prevent the first connector from falling off the first protrusion.

[0017] In the above-mentioned online dialysis dry powder packaging bag, the dry powder bag is provided with a second connector, the second connector is provided with a second assembly hole, the support plate is provided with a second protrusion opposite to the second assembly hole, the second protrusion is provided with a second buckle, and during installation, the second protrusion extends into the second assembly hole and is limited by the second buckle.

[0018] The second connector extends upwards, and the second mounting hole extends horizontally along the thickness direction of the second dry powder bag. The second connector has a certain degree of elasticity, allowing the second mounting hole to move within a certain range during assembly. The second protrusion extends horizontally along the thickness direction of the second dry powder bag. To better limit the movement, second buckles are provided on both opposite sides of the second protrusion. After assembly, the two second buckles prevent the second connector from falling off the second protrusion.

[0019] Compared with existing technologies, this online dialysis dry powder packaging bag has the following advantages: By installing dry powder bag one and dry powder bag two on the same support plate, online use of dry powder A and dry powder B can be used to prepare hemodialysis concentrate A and hemodialysis concentrate B, avoiding contamination of the concentrate; it is easy to install and has good stability after installation; it reduces transportation and storage costs and optimizes the requirements for equipment and environmental maintenance during solution preparation.
