Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to an arterial blood centrifugal separation device for autohemotherapy. Background Art

[0002] Autohemotherapy is a method of treatment that uses the patient's own blood components. It is widely used in the auxiliary treatment and health management of various diseases. With the development of medical technology, the demand for autohemotherapy is increasing, and in the process of autohemotherapy, the separation of arterial blood is a key link. To ensure the safety and effectiveness of treatment, the centrifugal separation device plays an important role in this process. The arterial blood centrifugal separation device separates different components in the blood by rotating the centrifuge tube at high speed to obtain components that meet the treatment requirements to ensure the treatment effect.

[0003] Existing arterial blood centrifugal separation devices generally use mechanical or electric drive structures to manually or semi-automatically complete the operation of taking and placing centrifuge tubes. However, most of these devices require operators to manually remove the reagent tubes, which increases the complexity and time cost of the operation. In addition, during the centrifugation and ejection process, the position of the centrifuge tube is often not effectively fixed and protected, causing the reagent tube to shift or tilt during the separation process, affecting the separation accuracy, and even causing the reagent tube to be damaged due to improper operation.

[0004] The main problem with the prior art is that after centrifugation, the removal process of the reagent tube still relies on manual operation, which not only increases the workload but also may cause damage to the reagent tube due to manual operation. The lack of a stable automatic ejection structure often makes it impossible to avoid the reagent tube from being subjected to impact during the ejection process, thereby affecting the integrity of the reagent tube and the safety of centrifugation. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an arterial blood centrifugal separation device for autohemotherapy, which solves the problem that after the centrifugal separation is completed, the removal process of the reagent tubes in the prior art still relies on manual operation, which not only increases the workload but also may cause the reagent tubes to be damaged due to human operation.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an arterial blood centrifugal separation device for autohemotherapy, comprising:

[0017] Preferably, the rotating rod is connected to the first fixed plate via a rotating shaft, so that during the driving process of the hydraulic rod, the rotating rod can rotate smoothly, thereby achieving a smooth ejection action, reducing mechanical resistance, and improving ejection efficiency.

[0022] Working principle: The box body is made of high-strength corrosion-resistant material, and contains a placement box, a centrifugal mechanism and a hydraulic control mechanism.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example:

[0037] Please see attached Figure 1 - Attachment Figure 7 The embodiment of the present invention provides an arterial blood centrifugal separation device for autohemotherapy, comprising:

[0038] The box body 1 is a rectangular structure with an internal storage space, made of high-strength corrosion-resistant materials, and is used to accommodate the placement box 11, the hydraulic control mechanism and the centrifugal mechanism. The structural design of the box body 1 ensures full utilization of the internal space and durability under the external environment;

[0039] The sealing cover 2 is connected to the top edge of the box body 1 through a hinge structure. Two first connecting rods 4 arranged in parallel are provided on the sealing cover 2. The first connecting rods 4 provide a stable supporting transmission effect when the sealing cover 2 is opened or closed, so as to ensure that the sealing cover 2 moves smoothly along a predetermined path during the opening process, thereby avoiding a decrease in sealing performance due to unstable opening and closing;

[0040] A first slide bar 3 and a second slide bar 5 are respectively installed on both sides of the box body 1. The first slide bar 3 and the second slide bar 5 are vertically arranged on the side wall of the box body 1 and are slidably connected with the sealing cover 2 to achieve smooth movement of the sealing cover 2 along the slide rail during the opening and closing process, and effectively avoid the left and right deviation of the sealing cover 2, thereby improving the structural stability of the device;

[0041] The protective plate 6 is fixedly installed on the outside of the box body 1. The protective plate 6 is fastened to the side wall of the box body 1 by multiple sets of bolts, and is used to provide protection for key components such as the centrifugal mechanism and the hydraulic control mechanism inside the device to prevent foreign matter from entering, and at the same time enhance the impact resistance of the device;

[0042] The top plate 7 is located above the protective plate 6 and is firmly connected to the box body 1 through multiple sets of fixed connection structures. A limit block 8 is provided below the top plate 7. The limit block 8 is embedded in the fixed groove of the top plate 7 to limit the opening angle of the sealing cover 2 to prevent the sealing cover 2 from being over-opened to expose the internal components, so as to maintain the sealing inside the device;

[0043] The centrifugal mechanism is installed below the placement box 11 and is driven by a second motor 26. The centrifugal mechanism is used to rotate the centrifuge tube at high speed to achieve effective separation of arterial blood during autohemotherapy. The hydraulic control mechanism includes a hydraulic rod 14 and a connecting block 15. The hydraulic rod 14 and the connecting block 15 are rotatably connected to the inner wall at the bottom of the placement box 11. The opening and closing actions of the sealing cover 2 and the top plate 7 are achieved through hydraulic control to meet the automatic control requirements. The hydraulic rod 14 is provided with a buffer device for providing buffering when the sealing cover 2 is opened or closed to reduce the impact on the centrifuge tube.

[0044] In one embodiment, when the device starts working, the sealing cover 2 is closed. Through the support and transmission action of the first connecting rod 4, the sealing cover can maintain a smooth path movement during the opening and closing process to prevent deviation and ensure that the sealing performance is not reduced. The first sliding bar 3 and the second sliding bar 5 installed on both sides of the box body 1 further ensure that the sealing cover moves smoothly along the slide rail without left and right deviation, thereby enhancing the structural stability of the device. The hydraulic rod 14 drives the connecting block 15 to realize the opening and closing action of the sealing cover 2 and the top plate 7. The hydraulic rod is provided with a buffer device to provide buffer protection when the sealing cover is opened or closed, thereby avoiding the equipment from causing impact on the centrifuge tube due to sudden opening and closing actions, thereby ensuring the safety and stability of the separation process. The automated design of the hydraulic control mechanism reduces manual intervention and improves the convenience and efficiency of equipment operation.

[0045] A limit plate 12 is provided on the top of the placement box 11. The limit plate 12 is made of high-strength alloy material and is fixed to the inner side of the top frame of the box body 1 by welding. The limit plate 12 is used to provide stable support during the placement of the centrifuge tube to prevent the centrifuge tube from shifting.

[0046] In one embodiment, by installing the limit plate 12, the centrifuge tube is firmly supported during high-speed rotation, thereby preventing the centrifuge tube from sliding or tilting due to equipment vibration or centrifugal force. This design ensures the accuracy of the centrifugal separation process, helps to obtain a stable and efficient separation effect, and ensures the quality of blood component separation during autohemotherapy.

[0047] A transverse plate 25 is provided inside the protective plate 6, and the transverse plate 25 is connected to the first motor 10. The first motor 10 drives the transverse plate 25 to reciprocate, thereby driving the opening and closing of the sealing cover 2 through the transmission action of the second connecting rod 9, thereby realizing automatic sealing control inside the device.

[0048] In one embodiment, the linkage design of the horizontal plate 25 and the first motor 10 ensures the stable opening and closing of the sealing cover 2, enables the sealing cover to move smoothly along a predetermined path, and avoids the degradation of the sealing performance due to unstable opening and closing, thereby ensuring the stability of the internal environment of the device. During the autohemotherapy process, the stability and pollution-free nature of the internal environment are extremely important. This design effectively improves the sealing effect of the device and ensures the safety and reliability of the separation process.

[0049] A first fixing plate 16 is provided inside the placement box 11, and a spring 20 is provided between the first fixing plate 16 and the cover plate 21. The spring 20 is used to eject the reagent tube inside the placement box 22. After the separation process is completed, the spring 20 provides an ejection force to facilitate the removal of the reagent tube and improve the convenience of operation.

[0050] In one embodiment, by setting a first fixed plate 16 inside the placement box 11 and installing a spring 20 between it and the cover plate 21, the device can automatically eject the reagent tube inside the placement box 22 after the separation process is completed. This design greatly simplifies the operation process, avoids manual intervention, and makes the removal of the reagent tube more convenient, especially improving work efficiency during frequent operations.

[0051] The hydraulic rod 14 is used to drive the first fixed plate 16. A side plate 13 is provided on the outside of the hydraulic rod 14 to protect the internal structure, so that the first fixed plate 16 drives the rotating rod 17 to rotate, thereby ejecting the first ejector rod 19, and further pushing the second ejector rod 24, so as to automatically eject the reagent tube inside the placement box 22, so as to facilitate the removal of the reagent tube after centrifugation.

[0052] In one embodiment, the hydraulic rod 14 drives the first fixed plate 16, which in turn drives the rotating rod 17 to rotate, thereby continuously pushing the first push rod 19 and the second push rod 24, thereby automatically ejecting the reagent tube in the placement box 22. This design realizes the automatic ejection function of the reagent tube, reduces the steps of manually removing the reagent tube after centrifugation, improves work efficiency, and is particularly suitable for high-frequency experimental operation requirements.

[0053] The rotating rod 17 is connected to the first fixed plate 16 via the rotating shaft 18, so that during the driving process of the hydraulic rod 14, the rotating rod 17 can rotate smoothly, realize a smooth ejection action, reduce mechanical resistance, and improve ejection efficiency.

[0054] In one embodiment, when the hydraulic rod 14 is started and drives the first fixed plate 16 to move, the first fixed plate drives the connected rotating rod 17 to rotate. The rotating rod 17 is connected to the first fixed plate 16 through the rotating shaft 18, so that during the transmission process, the rotating rod can flexibly rotate smoothly with the movement of the first fixed plate. The existence of the rotating shaft 18 provides a fulcrum for the rotating rod to rotate freely, thereby reducing the friction resistance during the rotation process.

[0055] A guide groove is provided between the first push rod 19 and the second push rod 24, and the lower surface of the second push rod 24 is fixedly connected to the second fixing plate 23 to ensure that the first push rod 19 remains aligned when driving the second push rod 24, so as to accurately eject the reagent tube inside the placement box 22 and avoid the reagent tube from being offset or stuck during the ejection process.

[0056] In one embodiment, during the operation of the device, the hydraulic rod 14 drives the first push rod 19 to move upward to eject the reagent tube. The ejection force of the first push rod is transmitted to the second push rod 24 through the guide groove. The guide groove provides a fixed trajectory for the movement of the first push rod, ensuring that the first push rod remains in a precise position during the ejection process and does not deviate from the direction.

[0057] The reagent tubes in the placement box 22 are fixed in a plurality of customized partition grooves, each of which is designed according to the shape and size of the reagent tube to ensure that the reagent tube is stable and does not shift during the centrifugation and ejection process to prevent the reagent tube from tilting or sliding.

[0058] In one embodiment, the reagent tubes are placed in a plurality of customized partitions inside the placement box 22. Each partition is designed according to the specific shape and size of the reagent tube to provide precise support and fixation. When the reagent tube is placed in the partition, the edge of the partition fits tightly against the outer wall of the reagent tube, so that the reagent tube will not be displaced or shaken during the entire operation. During the centrifugal separation process, the high-speed rotation of the second motor 26 will generate a strong centrifugal force. The reagent tube is fixed in the specified position by the partition to avoid tilting or sliding due to uneven force during rotation, thereby ensuring the accuracy of centrifugal separation. The structural design of the partition can effectively absorb some vibrations, further improve the stability of the reagent tube, and avoid displacement or damage caused by centrifugal force.

[0059] A buffer gasket is provided on the hydraulic rod 14 to absorb impact force during the ejection process, ensure smooth transmission between the first fixed plate 16, the rotating rod 17, the first ejector rod 19, and the second ejector rod 24, and prevent the reagent tube from being damaged due to excessive impact force.

[0060] In one embodiment, the buffer gasket on the hydraulic rod 14 can effectively absorb the impact force during the ejection process, preventing excessive force from being directly transmitted to the reagent tube during the transmission process, thereby avoiding damage to the reagent tube due to impact. This design improves the safety of the reagent tube, especially in continuous operation, and can effectively protect the reagent tube from damage.

[0061] The hydraulic rod 14 drives the first fixed plate 16 to drive the rotating rod 17, the first ejector rod 19, and the second ejector rod 24 in turn, so as to automatically eject the reagent tube inside the placement box 22, thereby reducing manual intervention and improving operation efficiency and safety.

[0062] In one embodiment, the hydraulic rod 14 serves as the main driving source to drive the first fixed plate 16 to move upward. The movement of the first fixed plate 16 is transmitted to the rotating rod 17 through a mechanical connection, driving it to rotate, further pushing the first ejector rod 19 to move upward, and the ejection action of the first ejector rod continues to be transmitted to the second ejector rod 24, causing the second ejector rod to move upward, gradually ejecting the reagent tubes inside the placement box 22 to a height that is convenient for the operator to take out. The entire process is controlled by the initial drive of the hydraulic rod 14, and a series of ejection actions are completed through the cooperation between the transmission components, forming a continuous and smooth automatic ejection process.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
