Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of syringe centrifugal processing, in particular to a centrifuge for syringes and a centrifugal process. BACKGROUND

[0002] At present, the centrifuge on the market has many problems when it is used for centrifugal operation of special syringes. The overall structure design of the traditional centrifuge is relatively general, and the adaptability of the special syringe rotor and adapter is not considered, which leads to inaccurate positioning and poor stability when the special components are installed and used. Moreover, the synergy of the driving system and control system of the traditional centrifuge with the special components is insufficient, which makes the centrifugal efficiency not high and cannot meet the demand of high-precision centrifugal processing of the sample in the special syringe. In addition, the safety protection structure of the traditional centrifuge is also difficult to completely adapt to the special working conditions of the special syringe during centrifugal operation, and there is a certain safety hazard.

[0003] It can be seen that the structure of the current centrifuge still needs to be improved, and it should be optimized to improve its adaptability to special syringes, ensure stable and reliable operation during centrifugal operation, and improve the precision and safety of centrifugal processing. Therefore, a more reasonable technical solution is needed to solve the technical problems in the prior art. SUMMARY

[0004] In view of the problems existing in the prior art, the present application discloses a centrifuge for syringes and a centrifugal process, which can adapt to special syringes by adjusting the structure of the centrifuge, maintain accurate positioning and high stability during centrifugal operation, and ensure the efficiency and safety of centrifugal processing.

[0005] In order to achieve the above purpose, the centrifuge disclosed by the present application can adopt the following scheme: A centrifuge for syringes, comprising: a machine body, a centrifugal cavity is arranged in the machine body, and a centrifugal container for carrying a syringe is arranged; the centrifugal containers are arranged at intervals on the circumference and are connected and fixed by a centrifugal rotor; a centrifugal rotor, comprising a circular rotor main body, a plurality of connection positions for cooperating with the centrifugal containers are formed on the rotor main body, and the centrifugal rotor is driven to rotate by a centrifugal driver; a centrifugal driver, which is fixedly arranged in the machine body and is used to drive the centrifugal rotor to rotate; a gas pressure balance structure, comprising an air inlet hole and an air outlet hole arranged at the centrifugal cavity, the air inlet hole is communicated with a sound-attenuating air inlet channel on the machine body, and the air outlet hole is communicated with a sound-attenuating air outlet channel on the machine body.

[0006] The centrifuge disclosed above rotates the centrifugal rotor by the centrifugal driver, rotates the syringe in the centrifugal container synchronously, and thus realizes the sedimentation separation of the substances in the syringe, and achieves the centrifugal processing effect. In the process, the air pressure balancing structure realizes the gas flow between the inside and outside of the machine body, can reduce the noise and temperature rise generated by the centrifugal rotor in the rotation process, and can also avoid the vibration of the machine body caused by air pressure imbalance, and thus ensures the stable and reliable centrifugal operation.

[0007] Further, the structure of the machine body can be configured in various forms to meet the requirement of forming sufficient space inside for centrifugal operation, and the structure is not uniquely limited, and one of the feasible options is proposed herein: the machine body includes a lower shell and a cover, and the inner container is arranged in the lower shell, and the cover is closed with the inner container to form a centrifugal cavity. When the above scheme is adopted, the lock body structure is formed between the lower shell and the cover, so that the cover forms an openable structure.

[0008] Further, since the centrifuge includes the air pressure balancing structure and the intake hole at the centrifugal cavity is communicated through the sound-attenuating air inlet channel, the sound-attenuating air inlet channel can be configured in various feasible options, and the structure is not uniquely limited, and one of the feasible options is proposed herein: the cover is hollow inside and is staggered with a plurality of turbulence strips, the turbulence strips form a bent sound-attenuating air inlet channel in the cover, and the side surface of the cover forms a plurality of air vents communicating with the sound-attenuating air inlet channel; the intake hole is arranged on the lower surface of the cover, and the air outside the machine body enters the sound-attenuating air inlet channel from the air vent and then enters the centrifugal cavity from the intake hole. When the above scheme is adopted, the turbulence strips are staggered on the hollow inner top and inner bottom of the cover to form a bent sound-attenuating air inlet channel, which can ensure the gas flow while increasing the sound wave propagation distance, improving the sound absorption efficiency, and reducing the noise.

[0009] In some schemes, the turbulence strips are fluffy and porous, and a plurality of conical turbulence protrusions are formed on the surface, which can ensure the gas flow while maximizing the absorption of the noise emitted from the inner container.

[0010] Further, when the centrifugal rotor in the centrifugal cavity rotates, it will cause the airflow in the centrifugal cavity to flow, so the gas is transported into the centrifugal cavity through the sound-attenuating air inlet channel, and the circulation of the gas is formed, and the specific structure is not uniquely limited, and one of the feasible options is proposed herein: the exhaust hole is arranged on the inner container and is uniformly and spacedly distributed along the circumferential wall of the inner container. When the above scheme is adopted, the exhaust hole is used to exhaust the gas in the centrifugal cavity to the outside.

[0011] Further, in order to protect the inner container and avoid shaking and collision of the centrifugal rotor during rotation, the outer part of the inner container is provided with a protective structure, which at least includes a protective shell spaced from the inner container, the inner surface of the protective shell is provided with a protective pad, and the protective pad and the inner container form a gap, and a weight reduction structure is formed on the protective shell. When the above scheme is adopted, the protective pad can be a foam pad, which can provide impact protection for the gas flow discharged from the inner container, ensure the stability of the inner container during centrifugal rotation, and provide shock absorption.

[0012] Further, the centrifugal container is used to place a syringe, and the structure thereof can be configured in various forms. Here, an optimal and feasible option is proposed: the centrifugal container includes a container cover and a container hanger, the container cover and the container hanger are connected to form a container cavity, the container cavity is provided with a normal adapter for fixing a syringe in a normal direction, or is provided with an inverted adapter for fixing a syringe in an inverted direction, and the normal adapter is internally formed with a groove corresponding to the injection end of the syringe. When the above scheme is adopted, the adapter is cylindrical, the outer wall surface thereof is attached to the inner wall surface of the centrifugal container, and the inner wall surface thereof is attached to the syringe, thereby achieving fixation of the syringe. When the adapter is arranged in different directions, the structure of the bottom of the adapter is different. When the injection end of the syringe is downward, the groove is matched with the injection end; when the tail end of the syringe is downward, the inner part of the adapter is flat, and directly attaches to the tail end of the syringe.

[0013] Further, the air pressure balancing structure is used to balance the air pressure inside and outside the separation cavity and ensure the stability of the separation cavity during separation rotation, and the structure thereof is not uniquely limited. Here, an optimal and feasible option is proposed: the air pressure balancing structure further includes a silencing device arranged in the main machine, and the silencing exhaust channel is connected to the silencing device to send the gas into the silencing device and then exhaust it outward. When the above scheme is adopted, the sound of the gas exhausted outward is effectively controlled and reduced.

[0014] Further, the silencing device can adopt various schemes, and the structure thereof is not uniquely limited. Here, an optimal and feasible option is proposed: the silencing device includes a silencing box, and a silencing piece is arranged in the silencing box to eliminate the noise generated when the gas is exhausted outward. When the above scheme is adopted, the silencing piece can be foam or other sound-absorbing structures.

[0015] The above disclosure relates to the structure of a centrifugal machine, and the present application also discloses a centrifugal method.

[0016] A syringe centrifugal process using the centrifugal machine described above, comprising: Place the injector combination adapter in the centrifuge container, according to the direction of the material to be separated, place the injector combination adapter vertically or upside down; Start the centrifuge and perform the first centrifugation operation to separate the material to be separated; After the first centrifugation operation is completed, the direction of the injector to be centrifuged again is reversed; Start the centrifuge for the second centrifugation operation to separate the material to be separated again; At least two centrifugation operations are performed to complete the centrifugation process.

[0017] The disclosed centrifugation process changes the direction of the injector during the first and second centrifugation operations according to the settling direction of the material, thereby achieving the separation of different materials with a single injector, improving the convenience of the separation operation, avoiding the operation of breaking the injector, and avoiding the pollution caused by sample transfer.

[0018] Further, the reversing operation of the injector during centrifugation can be performed in different ways. Here, one feasible option is optimized and proposed: during the centrifugation process, the injection end of the injector is downward during the first centrifugation operation, and the injection end of the injector is upward during the second centrifugation operation. When the above scheme is used, the orientations of the injector during the two centrifugation operations are different, and the settling directions of the separated materials are different, which can be separated by the injector.

[0019] Compared with the prior art, some beneficial effects of the disclosed technical solution include: The present application improves the stability and reliability of the centrifuge during the centrifugation operation by improving the structure of the centrifuge, ensures the smooth flow of air inside and outside the centrifuge, thereby ensuring air pressure balance, reducing temperature rise caused by rotor rotation, and reducing noise during centrifugation; At the same time, the direction of the injector is changed for centrifugation, and the separation process is performed according to the different settling directions of the materials, which simplifies the convenience of the material centrifugation and separation, and makes the centrifugation effect better.

[0032] In view of the fact that the centrifuge in the prior art has an unsatisfactory centrifugal processing effect and the centrifugal equipment is not stable enough, the following embodiments are optimized and overcome the defects in the prior art.

[0033] Embodiment 1 As shown in the drawings, the present embodiment provides a centrifuge for syringes to improve the convenience of centrifugal processing while ensuring the stability and reliability of the centrifugal processing. Figures 1-9

[0035] The machine body can be configured in various forms to meet the requirement of forming sufficient space inside for centrifugal operation, and the structure is not uniquely limited. In the embodiment, one of the feasible options is optimized and adopted: the machine body includes a lower shell 1 and a cover 2, the lower shell 1 is provided with an inner container 4, and the cover 2 is closed to form a centrifugal cavity.

[0036] Preferably, as shown in Figure 4 , Figure 5 The lock body structure 10 includes a lock body motor 1001, which drives the lock tongue 1002 to move to achieve locking and unlocking.

[0037] When the centrifugal rotor 9 in the centrifugal cavity rotates, it will cause airflow in the centrifugal cavity to flow, so that the sound-attenuating air inlet 202 is used to deliver gas to the centrifugal cavity, and a circulating flow of gas is formed. The specific structure is not uniquely limited, and one of the feasible options is optimized and adopted in the embodiment: the exhaust hole 401 is arranged on the inner container 4 and uniformly distributed along the circumferential wall of the inner container 4. When the above scheme is adopted, the exhaust hole 401 is used to exhaust the gas in the centrifugal cavity to the outside.

[0038] In order to protect the inner container 4 and avoid shaking and collision of the centrifugal rotor 9 during rotation, one of the feasible options is optimized and adopted in the embodiment: as shown in Figures 4-7 The outer part of the inner container 4 is provided with a protection structure, which at least includes a protection shell 5 spaced from the inner container 4, the inner surface of the protection shell 5 is provided with a protection pad 6, and the protection pad 6 and the inner container 4 form a gap, and a weight-reducing structure is also formed on the protection shell 5. When the above scheme is adopted, the protection pad 6 can be a foam pad, which can provide impact protection for the airflow discharged from the inner container 4, ensure the stability of the inner container 4 during centrifugal rotation, and provide shock absorption.

[0039] The centrifugal container 8 is used to place a syringe, and the structure can be configured in various forms. In the embodiment, one of the feasible options is optimized and adopted: as shown in Figure 8 , Figure 9As shown, the centrifugal container 8 comprises a container cover 801 and a container hanging body 802, the container cover 801 and the container hanging body 802 are in butt joint to form a container cavity, the container cavity is provided with a normal adapter 13 for fixing a syringe in normal direction, or is provided with an inverted adapter 11 for fixing a syringe in inverted direction, the normal adapter 13 is internally formed with a groove 12 corresponding to the injection end of the syringe. When the above scheme is adopted, the adapter is in a cylindrical shape, the outer wall surface of the adapter is in abutment with the inner wall surface of the centrifugal container 8, and the inner wall surface of the adapter is in abutment with the syringe, so that the syringe is fixed.

[0040] As shown in the drawings, Figure 4 , Figure 5 the centrifuge disclosed in the embodiment comprises the following structure: a centrifugal rotor 9 comprising a circular rotor main body, a plurality of connecting positions for matching the centrifugal container 8 are formed on the rotor main body, and the centrifugal rotor 9 is driven to rotate by the centrifugal driver 3.

[0041] Preferably, a plurality of abutting members 14 are arranged at the connecting positions, the abutting members 14 can adopt abutting bolts and the like, and are used to abut against the centrifugal container 8 to ensure that the centrifugal container 8 is installed stably and reliably.

[0042] the centrifuge disclosed in the embodiment comprises the following structure: a centrifugal driver 3 fixedly arranged in the machine body and used to drive the centrifugal rotor 9 to rotate.

[0043] Preferably, in the embodiment, the centrifugal driver 3 adopts a motor.

[0044] the centrifuge disclosed in the embodiment comprises the following structure: a gas pressure balance structure comprising an air inlet hole 403 and an air outlet hole 401 arranged at the centrifugal cavity, the air inlet hole 403 is communicated with the sound-attenuating air inlet channel 202 on the machine body, and the air outlet hole 401 is communicated with the sound-attenuating air outlet channel 402 on the machine body.

[0045] Since the centrifuge comprises the air pressure balance structure, and the air inlet hole 403 is communicated with the centrifugal cavity through the sound-attenuating air inlet channel 202, the sound-attenuating air inlet channel 202 can be configured in various feasible options, and the structure is not uniquely limited. In the embodiment, one feasible option is optimized and adopted: the cover 2 is hollow inside and staggered with a plurality of spoiler strips 201, the spoiler strips 201 form a bent sound-attenuating air inlet channel 202 inside the cover 2, and the side surface of the cover 2 forms a plurality of air vents communicating with the sound-attenuating air inlet channel 202; the air inlet hole 403 is arranged on the lower surface of the cover 2, and the air outside the machine body enters the sound-attenuating air inlet channel 202 from the air vent and then enters the centrifugal cavity through the air inlet hole 403. When the above scheme is adopted, the spoiler strips 201 are staggered on the inner top and inner bottom of the hollow cover 2, forming a bent sound-attenuating air inlet channel 202, which can ensure the flow of gas, increase the sound wave propagation distance, improve the sound absorption efficiency, and reduce the noise.

[0048] As shown in Figure 5 , Figure 7 The sound-attenuating device 7 can adopt various schemes, and the structure is not uniquely limited. In the embodiment, one feasible option is optimized and adopted: the sound-attenuating device 7 comprises a sound-attenuating box, and a sound-attenuating piece 701 is arranged in the sound-attenuating box to eliminate the noise generated when the gas is exhausted outward.

[0049] The centrifuge disclosed in the embodiment drives the centrifugal rotor 9 to rotate through the centrifugal driver 3, synchronously rotates the syringe in the centrifugal container 8, and realizes the sedimentation separation of the substances in the syringe, thereby achieving the centrifugal treatment effect. In this process, the air pressure balance structure realizes the gas flow inside and outside the machine body, reduces the noise of the centrifugal rotor 9 during the rotation, avoids the vibration of the machine body caused by the air pressure imbalance, and ensures the stable and reliable centrifugal operation.

[0050] According to the scheme disclosed in the embodiment, an actual case is listed here for illustration, and the specific settings in the case are as follows: 1. The gas pressure in the inner container 4 changes due to the rotation of the rotor. The gas enters the inner container 4 through the door cover gas channel (the gas channel is zigzag and arranged with sound-absorbing material), and then enters the box through the gas channel between the inner and outer containers (the gas channel is zigzag and arranged with sound-absorbing material). The gas outlet of the box is arranged with a gas outlet silencing device 7. The whole convection cooling system has good ventilation effect, and effectively reduces the noise generated by the rotation of the rotor.

[0051] 2. The cylindrical surface and the bottom surface of the inner container 4 are partially reinforced, and a lightweight design is made under the condition of avoiding resonance.

[0052] 3. A cylindrical pin is embedded on the motor shaft, and a pin groove is provided on the rotor. During operation, the main machine and the rotor can be prevented from slipping, and the safety performance is further improved.

[0053] 4. An RFID identification device is installed on the upper end of the motor shaft, which can monitor the information of the used rotor in more detail. The upper end surface of the device is a circular truncated cone, and a waterproof sleeve is arranged on the motor shaft, which can effectively prevent liquid from entering and contaminating the motor.

[0054] 5. The main machine has a speed, current, voltage, and temperature rise detection component, which can realize over-speed protection, rotor identification protection, overload, over-voltage, and over-current protection, and temperature rise protection.

[0055] 6. The motor assembly adopts a two-stage vibration reduction structure, and the main machine is more comfortable to use.

[0056] Embodiment 2 The above embodiment 1 discloses the structure of the centrifugal machine, and the embodiment further discloses a centrifugal method.

[0057] A centrifugal process for a syringe, using the centrifugal machine described above, comprises: S01: Place the syringe combined with the adapter in the centrifugal container 8, and place the syringe combined with the adapter in the forward direction or upside down according to the settling direction of the substance to be separated; S02: Start the centrifugal machine to perform the first centrifugal operation to separate the substance to be separated; S03: After the first centrifugal operation is completed, the direction of the syringe to be subjected to the second centrifugal treatment is reversed; S04: Start the centrifugal machine to perform the second centrifugal operation to separate the substance to be separated again; S05: Perform at least two centrifugal operations to complete the centrifugal treatment process.

[0058] The centrifugal process disclosed in the embodiment changes the direction of the syringe during the first centrifugal operation and the second centrifugal operation according to the different sedimentation directions of substances, so that the requirement of separating different substances by a single syringe can be realized, the convenience of the separation operation is improved, and the operation of breaking the syringe and the pollution possibly caused by sample transfer are avoided.

[0059] During the specific centrifugal treatment, the reversing operation of the syringe can adopt different schemes, and the embodiment is optimized and one of the feasible options is adopted: during the centrifugal treatment, the injection end of the syringe is downward during the first centrifugal operation, and the injection end of the syringe is upward during the second centrifugal operation. When the above scheme is adopted, the directions of the separated substances are different during the two centrifugal operations of the syringe, and the separated substances can be separated by the syringe.

[0060] According to the above disclosed method, a case is listed here for illustration. In the case, the process of the centrifugal operation is as follows: 1. Two same cup bodies and matched adapters are arranged at the symmetric positions of the rotor, i.e. the first centrifugal operation (the injection end of the syringe is downward), and the second centrifugal operation (the injection end of the syringe is upward).

[0061] 2. During the operation, the cup bodies marked for the first and second centrifugal operations and the adapters with the required capacity are prepared, and the adapters marked for the first and second centrifugal operations are placed in the corresponding cup bodies (the opening direction of the adapter is outward).

[0062] 3. One syringe of the same specification is filled with water and the liquid volume of the syringe containing the blood sample is balanced, or two syringes of the same blood sample volume are used, the injection end of the syringe is downward, and the syringe is placed in the adapter marked for the first centrifugal operation, the cup cover is screwed to the cup cover which cannot be easily rotated, the cup is placed on the corresponding hanging pin, the rotor nut is tightened, the same cup is symmetrically placed, and the first centrifugal operation can be started; After the centrifugal operation is completed, the syringe is taken out, the corresponding cup cover is tightened, the red blood cells are discharged, the plug is tightened, the injection end of the syringe is upward, the syringe is placed in the second centrifugal adapter, the cup cover is tightened, and the syringe is placed in the corresponding position. After confirming that there is no error, the second centrifugal operation is started. After the centrifugal operation is completed, the upper platelet-poor plasma is discharged, and the preparation of PRP (Platelet-rich plasma, platelet-rich plasma) is completed.

[0063] 4. The PRP preparation method does not need to break the syringe, the whole process uses one syringe, there is no blood sample transfer, the pollution risk is reduced, and various specifications are universal. The corresponding marks are made on the cup body and the adapter, which greatly facilitates the operation personnel.

[0064] 5. The rotor assembly has an anti-fumble design. If the syringe is placed in the second centrifugal adapter during the first centrifugal operation, the cup cover cannot be normally screwed, and vice versa, which greatly reduces the probability of errors of the operation personnel.
