Description

Technical Field

[0001] This application relates to the field of medical devices, and more particularly to a blood cell washing centrifuge. Background Technology

[0002] With the continuous advancement of medical technology, blood transfusion therapy has become an indispensable clinical treatment method. However, while traditional blood transfusion methods bring therapeutic benefits, they also come with certain risks, such as transfusion reactions and disease transmission. To reduce these risks, scientists have developed blood cell washing technology, which involves finely processing whole blood or suspended red blood cells to remove plasma, white blood cells, and other non-red blood cell components, thereby producing purer and safer red blood cell products.

[0003] Currently, the most common method for washing blood cells is manual washing, but the process is cumbersome and time-consuming, requiring 3-4 repetitions to complete the washing. Furthermore, the amount of liquid remaining during the process is unstable, which can easily lead to sample loss or high levels of washing solution residue. In addition, it requires a lot of manpower. Utility Model Content

[0062] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0063] Please see Figures 1 to 8 This application provides a blood cell washing centrifuge, including: a centrifuge shell 01, a centrifugation mechanism 02, a signal mechanism 03, a mixing mechanism 04, a washing mechanism 05, and a liquid storage chamber 06;

[0064] The centrifugation mechanism 02 is disposed inside the centrifuge housing 01. The centrifugation mechanism 02 includes a centrifuge support frame 021 and a centrifugation device 022. The centrifugation device 022 is disposed on the centrifuge support frame 021.

[0065] The signal mechanism 03 is located inside the centrifuge support frame 021, and the signal mechanism 03 is used to control the washing mechanism 05 to wash the blood cells.

[0066] The cleaning mechanism 05 is located on one side of the liquid storage chamber 06 and is mounted on the centrifuge support frame 021. A pipeline is provided below the cleaning mechanism 05 to connect to the liquid storage chamber 06, which is used to cooperate with the liquid storage chamber 06 to collect waste liquid and inject cleaning solution during the cleaning process.

[0067] The mixing mechanism 04 is located below the centrifuge support frame 021 and is used to mix the blood cell sample after centrifugation.

[0068] The components in this embodiment are described in detail below:

[0069] Centrifuge Housing 01: The centrifuge housing 01 is the main structure of the centrifuge, used to protect the internal components from external environmental influences such as dust, moisture, and vibration. The centrifuge housing 01 is typically made of robust and durable materials, such as metal or high-strength plastic, to ensure stability and safety during high-speed rotation. The housing also contains components for operating and controlling the centrifuge, such as a power button, control panel, and display screen.

[0070] Centrifugation Mechanism 02: Centrifugation mechanism 02 is the core component of the centrifuge, responsible for generating high-speed rotational force. This force applies centrifugal force to the sample or container placed inside the centrifuge, thereby achieving separation, concentration, precipitation, and other purposes. Centrifugation mechanism 02 includes components such as a motor, rotor, and bearings. The motor drives the rotor to rotate at high speed, moving the sample during the centrifugation process.

[0071] Signal mechanism 03: mainly used to detect the height of the hematocrit layer and the liquid layer, so as to accurately control the operation of the cleaning mechanism 05.

[0072] Mixing Mechanism 04: Primarily used to mix blood cells after waste liquid collection, ensuring thorough contact between the blood cells and the washing solution for more complete washing, thus guaranteeing consistency and accuracy in experimental or production processes. It may achieve mixing through stirring, vibration, rotation, or other methods.

[0073] Cleaning Unit 05: Cleaning Unit 05 is mainly used to absorb the waste liquid after blood cell washing and to inject washing solution into the test tubes to be washed, so as to wash the blood cells.

[0074] Liquid Storage Chamber 06: Liquid Storage Chamber 06 refers to the space or container outside the centrifuge used to store the liquid to be centrifuged. Liquid Storage Chamber 06 comes in different capacities and shapes to accommodate different types of samples and experimental needs. Liquid Storage Chamber 06 has excellent sealing properties, effectively preventing liquid leakage or contamination of other samples.

[0075] The experimenters first load the blood cell sample to be washed into the centrifuge device 022 and begin centrifugation. Supported by the centrifuge support frame 021, the centrifuge rotates at high speed. The centrifuge casing 01 provides protection for the entire device, ensuring safety and stability during operation. This step aims to initially separate different components in the blood cell sample, such as red blood cells, white blood cells, and platelets, using centrifugal force. The signaling mechanism 03 monitors the centrifugation process and stops centrifugation after reaching a specific speed or time, sending a signal to control the washing mechanism 05 to start. The washing mechanism 05 first draws the waste liquid from the centrifugation process through its lower pipeline and discharges it to the corresponding area of ​​the liquid storage chamber 06. Then, it draws washing solution from the liquid storage chamber 06 through its lower pipeline to wash the centrifuged blood cell sample, removing unwanted impurities or liquid. After washing, the mixing mechanism 04 starts working to homogenize the centrifuged and washed blood cell sample. This helps ensure the homogeneity of the blood cell sample, preparing it for subsequent experiments or treatments. The mixing mechanism 04 achieves uniform mixing of blood cells through vibration and rotation. Once all steps are complete, the researchers can stop the centrifuge and safely remove the processed blood cell sample.

[0076] Centrifugation and washing processes effectively remove impurities and unwanted liquid components from blood cell samples, improving the purity and quality of blood cells. Proper centrifugation and washing conditions help maintain the activity and function of blood cells, providing reliable samples for subsequent experiments or treatments. Signaling mechanism 03, washing mechanism 05, and mixing mechanism 04 enhance operational convenience and efficiency, reducing manual intervention and errors.

[0077] Optionally, the centrifuge support frame 021 includes: a centrifuge cover 0211, a motor storage chamber 0212, a centrifuge chamber 0213, and a centrifuge coil sleeve 0214;

[0078] The centrifuge cover 0211 is mounted on the centrifuge support frame 021 by a hinge;

[0079] The centrifuge chamber 0213 is disposed inside the centrifuge support frame 021;

[0080] The motor storage chamber 0212 is located below the centrifuge chamber 0213;

[0081] The centrifuge coil sleeve 0214 is installed on the bottom surface of the centrifuge chamber 0213, and a centrifuge coil placement opening is provided on the top of the centrifuge coil sleeve 0214 for installing the centrifuge device 022.

[0082] The centrifuge support frame 021 consists of a centrifuge cover 0211, a motor storage chamber 0212, a centrifuge chamber 0213, and a centrifuge coil sleeve 0214. The structural design of the centrifuge support frame 021 ensures the stability and safety of the equipment during high-speed rotation. The centrifuge cover 0211 is installed using a hinge, facilitating user operation while ensuring a tight seal during centrifugation. The centrifuge chamber 0213 provides rotation space for the centrifuge unit 022. The centrifuge coil sleeve 0214 is located in the center of the centrifuge chamber 0213 and is fixedly connected to the centrifuge housing 021 for mounting the centrifuge unit 02. The motor storage chamber 0212 is located below the centrifuge chamber 0213, providing space for the motors, including a centrifuge motor 0223, a washing mechanism motor 055, and a sample mixing mechanism motor 043.

[0083] Optionally, the centrifugation device 022 includes: a centrifugation disc 0221, a centrifugation shaft 0222, a centrifugation shaft gear 0223, a centrifugation tube basket 0224, a clamping strip 0225, and a centrifuge motor 0226;

[0084] The centrifugal shaft 0222 is installed below the centrifugal disc 0221, and a centrifugal shaft gear 0223 is provided below the centrifugal shaft 0222;

[0085] The centrifugal shaft gear 0223 is meshed with the gear of the centrifuge motor 0226 and is used to control the centrifugal disc 0221 to perform centrifugal operation.

[0086] The centrifuge motor 0226 is located inside the motor storage chamber 0212;

[0087] The centrifuge disc 0221 is provided with a plurality of arc-shaped grooves, and the locking strip 0225 is provided on both sides of the inner wall of the arc-shaped grooves. The arc-shaped grooves cooperate with the locking strip 0225 to lock the centrifuge tube basket 0224.

[0088] Centrifuge motor 0226 is installed in motor storage chamber 0212. When centrifuge motor 0226 starts, its power is transmitted to centrifuge shaft gear 0223 via gears. Centrifuge shaft gear 0223 meshes with the gears of centrifuge motor 0226 to ensure the accuracy and stability of power transmission. Centrifuge shaft 0222 begins to rotate under the action of centrifuge motor 0226, driving the centrifuge disc 0221 mounted above it to rotate as well. Centrifuge disc 0221 rotates at high speed, generating a strong centrifugal force, which is key to achieving blood cell separation. Centrifuge disc 0221 has multiple arc-shaped grooves, and each groove has a retaining strip 0225 on both sides of its inner wall. Centrifuge tube basket 0224 is fixed in the arc-shaped grooves by the retaining strips 0225, ensuring that it will not shake or fall off during centrifugation. When centrifuge disc 0221 rotates, the blood cell sample in centrifuge tube basket 0224 is subjected to centrifugal force and begins to separate. Under the action of centrifugal force, the different components in the blood cell sample begin to separate. Heavier components settle at the bottom of the centrifuge tube, while lighter components remain on top. This achieves highly efficient separation and purification of blood cells.

[0089] Optionally, the centrifuge tube basket 0224 is provided with slots 0227 on both sides above, and the centrifuge tube basket 0224 is connected to the clip 0225 through the slots 0227;

[0090] The centrifuge tube basket 0224 is provided with a signal inlet / outlet on its side;

[0091] An anti-slip pad inlet / outlet is provided below the centrifuge tube basket 0224.

[0092] The slots 0227 on both sides of the centrifuge tube basket 0224 match the retaining strips 0225 in the arc-shaped grooves on the centrifuge tray. When loading centrifuge tubes, align the slots of the centrifuge tube basket 0224 with the retaining strips 0225 on the centrifuge tray 0221, and gently push it in. The slots and retaining strips 0225 are tightly connected, ensuring that the centrifuge tube basket 0224 is stable and does not shake during centrifugation. After the sample is centrifuged, the centrifuge motor 0226 rotates and positions the centrifuge tube basket 0224 in the center of the signal mechanism 03. The signal mechanism 03 then sends a signal that passes through the test tubes and sample within the centrifuge tube basket 0224. Because the red blood cells separate into layers with the liquid after centrifugation, and the transmittance of the red blood cell layer is much lower than that of the liquid layer, the signal received by the signal mechanism 03 is different from that of the liquid layer. The signal mechanism 03 transmits the received signal to the system, which controls the washing mechanism 05 to move downwards into the test tubes within the centrifuge tube basket 0224 and aspirate the liquid. When it approaches the red blood cell layer, the system controls the washing mechanism 05 to stop moving downwards and to stop aspirating the liquid. An anti-slip pad inlet / outlet is located at the bottom of the centrifuge tube basket 0224 to place an anti-slip pad 042 at the bottom of the test tubes. The anti-slip pad 042 increases the friction between the centrifuge tube basket 0224 and the centrifuge tray 0221, preventing slippage or detachment during high-speed rotation. When it is necessary to replace the anti-slip mat 042, the operation can be carried out through the anti-slip mat inlet and outlet, ensuring that the replacement of the anti-slip mat 042 is convenient and quick and does not affect the centrifugation process.

[0093] Optionally, the signal mechanism 03 includes: a signal transmitting mechanism 031 and a signal receiving mechanism 032;

[0094] The signal transmitting mechanism 031 is installed on the inner wall of the centrifuge chamber 0213;

[0095] The signal receiving mechanism 032 is installed on the outer wall of the centrifugal coil sleeve 0214.

[0096] Signal transmitting mechanism 031 is installed on the inner wall of centrifuge chamber 0213 and is responsible for monitoring specific parameters or states during centrifugation. When centrifugation is complete, signal transmitting mechanism 031 sends a signal, which signal receiving mechanism 032 immediately captures and transmits to the centrifuge's control system. Upon receiving the signal, the control system processes it according to preset values.

[0097] Optionally, the mixing mechanism 04 includes a mixing mechanism telescopic rod 041, an anti-slip pad 042, and a mixing mechanism motor 043;

[0098] The anti-slip pad 042 is installed above the telescopic rod 041 of the mixing mechanism;

[0099] A mixing mechanism gear is installed below the telescopic rod 041 of the mixing mechanism, and the mixing mechanism gear is meshed with the gear of the mixing mechanism motor 043.

[0100] The mixing mechanism motor 043 is located inside the motor storage chamber 0212.

[0101] The lower end of the mixing mechanism telescopic rod 041 has a gear, which meshes with the gear of the mixing mechanism motor 043. The upper end of the mixing mechanism telescopic rod 041 is fixedly connected to the anti-slip pad 042. The mixing mechanism 04 is located at the bottom of the centrifuge chamber. When the test tubes in the centrifuge tube basket 0224 directly above the inlet and outlet of the mixing mechanism 04 need to be mixed, the mixing mechanism telescopic rod 041 moves upward, carrying the anti-slip pad 042 through the mixing mechanism inlet and outlet, and further through the anti-slip pad inlet and outlet, contacting the bottom of the test tube. At this time, the mixing mechanism motor 043 starts, driving the mixing mechanism telescopic rod 041 and the anti-slip pad 042 to rotate, thereby achieving the mixing effect. The anti-slip pad 042 has a pressure sensor. Its function is that when the mixing mechanism telescopic rod 041 and the anti-slip pad 042 move upward and feel the set pressure when they contact the bottom of the test tube, the pressure sensor transmits a signal to the system, thereby controlling the mixing mechanism telescopic rod 041 to stop moving upward and starting the sample mixing mechanism motor 043.

[0102] Optionally, the cleaning mechanism 05 includes: a first telescopic rod 051, a rotating arm 052, a second telescopic rod 053, a cleaning needle 054, and a motor 055.

[0103] A cleaning mechanism gear is installed below the first telescopic rod 051 of the cleaning mechanism, and the cleaning mechanism gear is meshed with the gear of the cleaning mechanism motor 055.

[0104] The cleaning mechanism motor 055 is installed inside the motor storage chamber 0212;

[0105] The rotating arm 052 is installed above the first telescopic rod 051 of the cleaning mechanism;

[0106] The upper end of the second telescopic rod 053 of the cleaning mechanism is mounted on the rotating arm 052;

[0107] The cleaning needle 054 is installed below the second telescopic rod 053 of the cleaning mechanism.

[0108] The lower end of the first telescopic rod 051 of the cleaning mechanism has a gear, which meshes with the gear of the cleaning mechanism motor 055. The upper end of the first telescopic rod 051 is fixedly connected to the rotating arm 052. The purpose of this is that the cleaning mechanism motor 055 provides power to the cleaning mechanism 05, allowing the first telescopic rod 051 to move up and down during operation, thus driving the rotating arm 052, the second telescopic rod 053, and the cleaning needle 054 to move up and down. The rotating arm 052 serves as a bridge connecting the first telescopic rod 051 and the second telescopic rod 053. The upper end of the second telescopic rod 053 is fixedly connected to the rotating arm 052, and the lower end is fixedly connected to the cleaning needle 054. This allows the second telescopic rod 053 to drive the cleaning needle 054 to move up and down during operation, providing power for its movement.

[0109] Optionally, a rotating wheel 056 is installed on the second telescopic rod 053 of the cleaning mechanism, and the rotating wheel 056 is provided with an annular groove and a pressure sensing device.

[0110] The upper part of the second telescopic rod 053 of the cleaning mechanism is fixedly connected to the lower end of a rotating wheel 056. The rotating wheel 0565 has an annular groove, which helps to fix the test tube. When the second telescopic rod 053 of the cleaning mechanism reaches directly above the inlet and outlet, the first telescopic rod 051 of the cleaning mechanism moves downward, which drives the second telescopic rod 053 of the cleaning mechanism to move downward. The rotating wheel 056 on the upper part of the second telescopic rod 053 of the cleaning mechanism contacts the test tube in the centrifuge tube basket 0224. The mouth of the test tube enters the annular groove on the rotating wheel 056. The telescopic rod 041 of the mixing mechanism and the anti-slip pad 042 move upward, pressing against the bottom of the test tube and fixing the test tube between the anti-slip pad 042 and the rotating wheel 056. At this time, the test tube is suspended in the centrifuge tube basket 0224, that is, the test tube is not in contact with the centrifuge tube basket 0224. When the motor 043 of the mixing mechanism starts, it drives the telescopic rod 041 of the mixing mechanism, the anti-slip pad 42, the test tube, and the rotating wheel 056 to rotate simultaneously to mix the sample. The rotating wheel 056 has a pressure sensing device. When the first telescopic rod 051 of the cleaning mechanism moves downward, it drives the second telescopic rod 053 of the cleaning mechanism to move downward. When the rotating wheel 056 contacts the test tube and senses the set pressure, the pressure sensing device transmits a signal to the system, thereby controlling the first telescopic rod 051 of the cleaning mechanism to stop moving downward.

[0111] Optionally, the pipelines of the cleaning mechanism 05 include: a washing liquid pipe 057, a waste liquid pipe 058, a pressure pump 059, and a sensing device 0510.

[0112] Both the washing liquid pipe 057 and the waste liquid pipe 058 are equipped with pressure pumps 059.

[0114] The washing solution tube 057 is connected to the liquid storage chamber 06 and is used in conjunction with the pressure pump 059 to inject the washing solution into the sample.

[0115] The waste liquid pipe 058 is connected to the liquid storage chamber 06 and is used in conjunction with the pressure pump 059 to treat the waste liquid of the sample.

[0116] The upper end of the cleaning needle 054 is fixedly connected to the lower end of the second telescopic rod 053 driving the cleaning mechanism. The cleaning needle 054 has two channels: a liquid suction channel and a liquid discharge channel. The liquid suction channel is connected to a waste liquid pipe 058, and the liquid discharge channel is connected to a washing liquid pipe 057. Both the washing liquid pipe 057 and the waste liquid pipe 058 are connected to pressure pumps 059, which provide power for liquid injection and suction. The ends of both the washing liquid pipe 057 and the waste liquid pipe 058 are connected to sensors to monitor the liquid level in the liquid storage chamber 06.

[0117] Optionally, the liquid storage chamber 06 includes: a washing liquid storage chamber 061, a waste liquid storage chamber 062, and an alarm device 063;

[0118] The washing liquid storage chamber 061 and the waste liquid storage chamber 062 are both located on one side of the centrifuge support frame 021;
