Description

Technical Field

[0001] This utility model belongs to the technical field of blood processing equipment, specifically relating to a multi-unit balancing system. Background Technology

[0002] A blood balancing device is primarily used during blood component separation to ensure that all blood bags within a centrifuge have the same or similar weight, thereby improving separation efficiency and preventing centrifuge damage. Different blood components, due to differences in sedimentation coefficients, will settle at different speeds under centrifugal force, forming zones with varying density gradients, thus achieving blood component separation. During this process, the blood to be separated is placed in blood bags and then into the centrifuge. If the blood bags are of inconsistent weight, the centrifuge will experience uneven stress during operation, not only reducing separation efficiency but also easily damaging the centrifuge. Therefore, balancing the blood bags is essential.

[0003] Existing plasma balancing devices are primarily based on the weighing principle. They detect the weight of plasma bags using a weighing platform, transmit the weight data to the control system for processing, and thus achieve weight balancing of the plasma bags. Their basic structure typically includes the main body, a weighing platform mounted on the main body, a display screen for showing the weight data, and an internal data processing module. Currently, existing balancing devices have at least two weighing platforms. To balance multiple plasma bags at once, there are generally two methods: one is to set up several weighing platforms on a single machine, and the other is to use multiple machines to weigh the bags simultaneously and then manually compare the weight data for pairing. Both methods require manual monitoring of the data from each weighing platform to complete the balancing process, resulting in high human intervention and cumbersome operation, leading to low balancing efficiency and failing to meet the requirements for efficient and accurate balancing.

[0030] Example 1:

[0031] This embodiment discloses a multi-unit balancing system, which is mainly used in the pairwise balancing process of blood bags before centrifugation. Because when centrifuging to separate serum and plasma, an even number of blood bags with almost the same weight are required, otherwise the centrifugation process will be unstable. Therefore, it is necessary to balance several blood bags before centrifugation, that is, to find pairs of blood bags with a weight difference of less than a limit to pair up.

[0032] The common method is to weigh each blood bag and then manually select and match them. This process is inefficient. The existing balancing device is based on the structure of an electronic scale with special structural improvements and program optimizations. This allows an even number of weighing areas to be set on a single balancing device, which can meet the requirement of weighing and matching multiple blood bags at the same time. This allows the device to find blood bags with matching weights among several blood bags for centrifugation.

[0033] The multi-unit balancing system provided in this embodiment is based on the existing single balancing instrument. Through modular structural design, it enables multiple balancing instruments to be connected as the smallest unit, forming an array for balancing several blood bags, as detailed below:

[0034] The multi-unit balancing system in this embodiment includes several independent units 1. Each unit 1 is a benchtop structure with independent power supply and includes a casing and a circuit board inside the casing. A conventional weighing platform 3 is provided on top of each unit 1, and each unit 1 has at least two weighing platforms 3 to ensure that each unit 1 can be used independently.

[0035] The machine body 1 is also equipped with a display screen 2, which is connected to a circuit board to display weighing data. After powering on, the display screen 2 displays the number of weighing platforms 3 corresponding to each weighing platform 3 set in each machine body 1. Each area uses numbers as the main display, with a constantly lit weighing platform 3 number and unit identification, directly displaying the current weight value of each weighing platform 3. When the difference between two weights is less than a set threshold, it is indicated on the display screen 2 with a specific color background or other conspicuous markings, allowing the operator to find the corresponding blood bag for matching based on the corresponding weighing platform 3 number.

[0036] To address the issue in existing technologies where data is not shared between individual machines 1, requiring manual screening of blood bags across machines 1, this embodiment further includes a signal module 6 on machine 1, which is connected to the circuit board of machine 1. Several signal ports 7 are also provided on machine 1, connected to the signal module 6. Data exchange between two machines 1 is achieved by inserting signal lines 4 corresponding to the signal ports 7.

[0037] In this embodiment, the signal port 7 can adopt various specifications, including serial ports of various types such as RJ45, USB, and RS485, or common video signal output ports such as HDMI and DP interfaces. In this embodiment, the commonly used RJ45 port is used as the specification of the signal port 7, and the signal cable 4 is a wire harness with signal terminals at both ends, used to connect the signal ports 7 of the two units 1 for communication.

[0038] This data connection method enables data exchange across multiple machine bodies 1. Essentially, it utilizes signal module 6 as an independent structure to enhance data exchange functionality. This independent signal module 6 is responsible for handling the communication logic across multiple machine bodies 1. Signal module 6 includes a network protocol stack supporting UDP / TCP communication, a data buffer storing the weighing data of each machine body 1, and a communication status monitoring unit to detect the link connection status.

[0039] When multiple units 1 are connected in series, to ensure power supply stability, a DC-DC isolation module can be used to provide a separate power supply for the data module, avoiding ground loop interference. The differential signal lines 4 of the RJ45 interface need to be lengthened to reduce signal distortion.

[0040] In another embodiment, the signal module 6 is integrated on the circuit board of the body 1 and is directly connected to the signal port 7 provided on the body 1. The embedded program is integrated on the MCU of the circuit board, and the signal module 6 is only used for signal processing.

[0041] When multiple devices are connected (1), RJ45 is used as signal port 7, typically in a serial connection, meaning one device (1) connects to another device (1) sequentially, including two end devices and several intermediate devices (1) connecting two devices (1) to each other. In this method, the first connected device (1) is the default master. When a new device connects, it announces its identity via a broadcast packet and periodically synchronizes weighing data using a master-slave or peer-to-peer mode. In other words, device discovery and networking occur when a device sends a broadcast packet to announce its existence upon power-on. The received broadcast packets establish the device topology, connecting multiple devices in a daisy-chain configuration and automatically assigning unique IDs. The master device then periodically broadcasts synchronization frames, and slave devices immediately reply with their current weighing data upon receiving the synchronization frames. Through this hardware and software design, data sharing and balancing prompts for multiple devices connected in series can be achieved. When the weight difference of blood bags on two devices (1) is within a threshold, the corresponding display screen (2) will display a specific color to indicate successful balancing; otherwise, a red display will indicate unbalanced balancing.

[0042] Furthermore, this embodiment proposes several practical configuration methods for the balancing system of the aforementioned multi-split air conditioner, referring to... Figures 2-5 The image shows how the two units 1 are connected and used.

[0043] The machine body 1 in the figure adopts a structural design similar to an electronic scale. The outer shell is a tabletop structure with a sloping front, which allows for a large surface area while maintaining a certain thickness, for the centrally located display screen 2 and corresponding operation panel. The top of the machine body 1 is a large top plate area, where several weighing platforms 3 are evenly spaced and movable relative to the machine body 1. Each weighing platform 3 is independently and movablely connected to the machine body 1, and can weigh the weights of the weight sensors installed inside the machine body 1. Each machine body 1 has six weighing platforms 3, and a single machine body 1 can simultaneously weigh and balance six blood bags.

[0044] On the back of unit 1, there is a dedicated connection surface with several ports providing corresponding functions. (See reference) Figure 2 and Figure 3 The main body 1 has a three-hole power interface 5, which is connected to an external socket via a power cord to supply power to the main body 1. Then, several ports are set in the left side area, including two signal ports 7, a first signal plug 8 of USB specification and a second signal plug 9 of RS485 specification. Both of these signal plugs can be connected to external terminal devices for data exchange, and can also be used to burn the program of the control module inside the main body 1.

[0045] As can be seen, in this embodiment, signal port 7 consists of two symmetrically arranged RJ45 network ports, and there is also a separate RJ45 network port on the body 1, which can be connected to the network to realize remote data interaction.

[0046] Based on the scheme shown in the figure, the two machines 1 are connected by a signal cable 4, and the signal plug 10 of the signal cable 4 is inserted into the corresponding signal port 7, thereby realizing data sharing between the two machines 1. In use, after the power-on self-test process of the two machines 1 is completed, the blood bags are placed on the weighing platforms 3 of the two machines 1. The display screens 2 of the two machines 1 display the mass of the blood bags on the weighing platforms 3 with corresponding numbers in six areas. Once it is found that the masses on these 12 weighing platforms 3 are paired, the display screen 2 will flash a specific background color or use other prompts to indicate that the operator can quickly find the corresponding blood bags for pairing and centrifugation.

[0047] Furthermore, refer to Figure 1 , Figure 4 and Figure 5 The diagram shows a connection scheme for four units 1. The units 1 shown are placed side-by-side and connected in pairs via signal cables 4 on their backs. (Refer to...) Figure 5As can be seen, two signal lines 4 are connected to the middle unit 1, thus enabling the four units 1 to be connected in series. Similar to the above scheme, the 24 weighing platforms 3 on the four units 1 can simultaneously match weights and use different colors or other prompts to indicate pairing. If the threshold is set low enough, more weighing platforms 3 are needed to achieve effective pairing.

[0048] Furthermore, refer to Figure 6 The figure shows another configuration. To achieve array placement, a signal port 7 is provided on each side of the main unit 1. Side-by-side main units 1 are connected via a short cable 401, while adjacent main units 1 on opposite sides are connected in series via a long cable 402 on the same side, achieving multi-unit series connection in a Z-shaped rotation. This configuration is also more convenient for wiring and arrangement compared to ports on the back. In other embodiments, a rigid connection structure can replace the short cable 401 between two adjacent main units 1, i.e., a connection structure folded and fixed to the side of the main unit 1. During connection, simply plugging and fixing the two main units 1 together achieves data connection.

[0049] This utility model is not limited to the optional embodiments described above, and anyone can derive other various forms of products under the guidance of this utility model. The specific embodiments described above should not be construed as limiting the scope of protection of this utility model. The scope of protection of this utility model shall be determined by the claims, and the description can be used to interpret the claims.
