Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a blood separation device and method with a call function. Background Technology

[0002] Clinical blood tests can be divided into general blood tests, laboratory tests for hemolytic anemia, bone marrow cytology tests, blood typing, and crossmatching. They can detect the hematological characteristics of common blood diseases. Blood separation devices are essential equipment for blood testing; currently, centrifuges are generally used to separate blood samples.

[0003] In the prior art, such as the portable medical blood centrifuge with publication number CN106475235B, there is a base with an inner liner inside. A centrifuge assembly is located within the inner liner. A cover is hinged to the top of the base. The centrifuge assembly includes a triangular plate with a spring fixed below it in a spring seat, which is also fixed within the inner liner. A motor is located below the triangular plate, with a rotating shaft at its output end. A rotating disk is located at the top of the rotating shaft, and a first and second cup are installed within the rotating disk. Both the first and second cups are sealed. This invention improves upon existing medical blood centrifuges. The triangular plate and three sets of springs in the centrifuge assembly provide stability and cushioning. The rotating disk can hold two sets of blood containers, allowing for a larger number of samples to be tested at once. Furthermore, the device's structure is reasonable, effectively reducing its weight.

[0004] The above technical solution has some problems in practical application. In order to facilitate the handling of samples, the samples are inserted vertically into the device. However, when the vertically inserted samples are centrifuged, the separated samples are not easy to separate into layers, and a static separation process is required, resulting in low separation efficiency.

[0005] Therefore, it is necessary to invent a blood separation device and method with a call function to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a blood separation device and method with a call function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a blood separation device with a call function, comprising:

[0008] The main body of the equipment has a processing cavity, which is used for;

[0009] A drive shaft, which is rotatably mounted inside the machining cavity;

[0010] The turntable is detachably mounted on the drive shaft;

[0011] The feeding rack has multiple rotating feeders located on the outside of the turntable. The top of the feeding rack is fixed with a connecting arm, which is rotatably located on the outside of the turntable via a pin. The bottom of the feeding rack is fixed with a positioning sleeve, and slots are provided on both sides of the positioning sleeve. The slots are equipped with movable clamps.

[0012] Sample bottles, which are detachably installed inside the material rack, are used to store blood samples;

[0013] The sample bottle is mounted on the outside of the turntable via a feeding rack. The power shaft drives the feeding rack and the sample bottle to rotate via the turntable to separate serum and plasma in the blood within the sample bottle.

[0014] Preferably, a pressure seat is located at the bottom of the inner part of the feeding rack. A pressure rod is fixedly provided at the bottom of the pressure seat, and the pressure rod is slidably provided at the bottom of the feeding rack. A connecting seat is fixedly provided at the bottom of the pressure rod. The connecting seat is located below the feeding rack, and a spring is provided between the connecting seat and the feeding rack. Movable arms are movably provided on both sides of the connecting seat through pins. A support arm is movably provided at one end of the movable arm through a pin, and the top end of the support arm is fixedly provided at the bottom of the clamping plate. The sample bottle applies pressure to the pressure seat under the action of centrifugal force so that the connecting seat moves away from the feeding rack. The connecting seat drives the clamping plate to move inward through the movable arm and the support arm so that it clamps the sample bottle.

[0015] The inner wall of the clamp is provided with a silicone pad.

[0016] Preferably, a connecting rod is movably provided at the bottom end of the support arm via a pin, and a fixing plate is fixed at both ends of the connecting rod. The fixing plate is fixed at the bottom end of the feeding rack, and the fixing plate and the connecting rod restrict the range of motion of the support arm.

[0017] Preferably, the spline shaft and spline groove are provided, with the spline shaft fixedly disposed in the middle of the power shaft and the spline groove disposed in the middle of the turntable. The spline shaft and spline groove are used to realize the connection between the turntable and the power shaft.

[0018] Preferably, the limiting groove and the limiting block are provided. The limiting groove is a ring structure and is located on the outside of the power shaft near the top. Multiple limiting blocks are provided and can be slidably disposed inside the turntable. The limiting blocks and the limiting groove are used to limit the connection between the turntable and the power shaft.

[0019] Preferably, there are multiple through slots, all of which are opened inside the turntable, and the multiple limiting blocks are slidably disposed in the multiple through slots;

[0020] An extension rod, which is designed as an inclined structure and located at one end of the limiting block;

[0021] The pressure plate is located inside the connecting arm. When the connecting arm is flipped, the pressure plate squeezes the extension rod, and the extension rod drives the limiting block to slide so that it is inserted into the limiting groove to lock the position between the turntable and the power shaft.

[0022] Preferably, a strip groove is provided through the middle of the limiting block, and a fixing block is provided through the inside of the strip groove. The fixing block is fixed in the groove, and a spring is provided between the fixing block and the strip groove.

[0023] Preferably, the bottom end of the power shaft is provided with a power motor, and the power motor is located inside the main body of the equipment.

[0024] Preferably, a call module is located on the outside of the main body of the device. The call module includes a timer controller, a speaker, and a power supply. The call module is used to send a call message to remind the user after the device has been turned on for a certain period of time.

[0025] A blood separation method using a blood separation device with a call function includes the following steps:

[0026] Step 1: Sample placement. Place the blood to be separated into sample bottles, and then place the sample bottles into multiple material racks. Finally, place the material racks onto the drive shaft.

[0027] Step 2, sample separation: The power motor inside the main body of the control device drives the power shaft to rotate. The power shaft drives the sample bottle to rotate at high speed through the turntable and feeding rack, so that the serum and plasma in the blood sample in the sample bottle are separated into layers under the action of centrifugal force. When starting the power motor, press the timer controller in the call module at the same time.

[0028] Step 3: Sample Removal. After the equipment has been running for a period of time, the speaker in the call module will issue a call message, and the motor will stop rotating. At this time, the feeding rack can be removed, and multiple sample bottles can be removed one by one.

[0029] The technical effects and advantages of this invention are as follows:

[0030] 1. This invention features a power shaft, a turntable, a feeding rack, and sample bottles. The sample bottles are fixed to the outside of the turntable by the feeding rack, and the feeding rack and the turntable are connected in a flip-out manner. When picking up or putting down the sample bottles, the feeding rack remains vertical under the action of gravity. When centrifuging to separate the samples, the feeding rack and the sample bottles flip under the action of centrifugal force, making the sample bottles tend to be in a parallel position, so as to facilitate the stratification of the samples inside the sample bottles. After the sample bottles return to a vertical position, the stratified samples can retain their stratified state, thereby eliminating the need for static stratification. This invention facilitates the picking up and putting down of sample bottles while improving the stratification efficiency of the device.

[0031] 2. The turntable and the drive shaft are connected by a splined shaft and splined groove for a detachable plug-in connection. When picking up and putting down sample bottles, the turntable can be directly removed for easy handling.

[0032] 3. This invention sets up a feeding rack, sample bottles, positioning sleeves, and clamps. The sample bottles are inserted into the feeding rack by insertion. When the sample bottles rotate at high speed with the feeding rack, the sample bottles apply pressure to the pressure seat at the bottom of the feeding rack under the action of centrifugal force. The pressure seat drives the clamps to move through the pressure rod, connecting seat, movable arm, and support arm to clamp the sample bottles, thereby avoiding the sample bottles from shaking and colliding with the feeding rack during rotation and being damaged.

[0033] 4. This invention, by setting a limiting groove, a limiting block, an extension rod, and a pressure plate, allows the connecting arm to rotate under centrifugal force as the turntable rotates with the power shaft. The connecting arm then presses the extension rod through the pressure plate, causing the limiting block to insert into the limiting groove. This improves the connection stability between the power shaft and the turntable, thus preventing loosening due to high-speed rotation. Consequently, it facilitates the overall loading and unloading of the turntable, the feeding rack, and sample bottles while ensuring the stability of the equipment during operation.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1

[0045] like Figures 1 to 8 As shown, the blood separation device with a call function provided by the present invention is essentially a blood centrifuge that can pick up and put in blood samples in a vertical state and centrifuge blood samples in a horizontal state. By setting a detachable turntable 4 in the main body 1 of the centrifuge, when picking up and putting in blood sample bottles 6, the turntable 4 and the feeding rack 5 can be removed as a whole. After removal, the feeding rack 5 remains vertical under the action of gravity. At this time, the sample bottle 6 can be directly inserted into the feeding rack 5. During blood centrifugation, the feeding rack 5 drives the sample bottle 6 to flip under the action of centrifugal force, so that the horizontal sample bottle 6 tends to be horizontal. The sample in the horizontal sample bottle 6 completes the separation under the action of centrifugal force. After the equipment stops, the sample bottle 6 and the feeding rack 5 lose the action of centrifugal force and return to the vertical state. At this time, the sample in the sample bottle 6 remains separated, so the separation of serum and plasma in blood can be completed without standing for separation.

[0046] In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment. In this embodiment, no special limitations are imposed.

[0047] In this embodiment, a blood separation device with a call function includes:

[0048] The main body of the equipment 1 has a circular processing cavity 2;

[0049] The power shaft 3 is rotatably located inside the machining cavity 2;

[0050] Turntable 4, whose detachable plug-in is located near the top of drive shaft 3;

[0051] The spline shaft 31 and spline groove 32 are fixedly located in the middle of the power shaft 3 and the spline groove 32 is located in the middle of the turntable 4. The spline shaft 31 and spline groove 32 are used to realize the connection between the turntable 4 and the power shaft 3. In other embodiments, the connection between the turntable 4 and the power shaft 3 can also be realized by snap-fit, screw connection or other means.

[0052] The limiting groove 33 and the limiting block 34 are provided. The limiting groove 33 is a ring structure and is opened on the outside of the power shaft 3 near the top. Multiple limiting blocks 34 are provided and can be slidably disposed inside the turntable 4. The limiting block 34 and the limiting groove 33 are used to limit the connection between the turntable 4 and the power shaft 3.

[0053] Multiple through slots 35 are provided and are all opened inside the turntable 4, and multiple limiting blocks 34 are slidably provided in the multiple through slots 35.

[0054] Extension rod 36, which is designed as an inclined structure and located at one end of limit block 34;

[0055] The pressure plate 37 is located inside the connecting arm 51. When the connecting arm 51 is flipped, the pressure plate 37 presses the extension rod 36. The extension rod 36 drives the limiting block 34 to slide and insert it into the limiting groove 33 to lock the position between the turntable 4 and the power shaft 3.

[0056] A strip groove 341 is provided through the middle of the limiting block 34, and a fixing block 342 is provided through the inside of the strip groove 341. The fixing block 342 is fixed in the through groove 35, and a spring is provided between the fixing block 342 and the strip groove 341. The spring is used to provide a force to the limiting block 34 away from the power shaft 3, so that it separates from the limiting groove 33 when the device stops, so that the turntable 4 can be removed.

[0057] A power motor is provided at the bottom of the power shaft 3, and the power motor is located inside the main body 1 of the equipment;

[0058] The feeding rack 5 has multiple rotating parts located on the outside of the turntable 4. The top of the feeding rack 5 is fixedly provided with a connecting arm 51, which is rotatably located on the outside of the turntable 4 via a pin. The bottom of the feeding rack 5 is fixedly provided with a positioning sleeve 52. The positioning sleeve 52 has slots 53 on both sides. The slots 53 have movable clamps 54 inside, and the inner side wall of the clamps 54 is provided with a silicone pad 541. The silicone pad 541 prevents the clamps 54 from damaging the sample bottles 6.

[0059] The pressure seat 55 is located at the bottom of the inner part of the feeding rack 5. The bottom end of the pressure seat 55 is fixedly provided with a pressure rod 56, and the pressure rod 56 is slidably provided at the bottom end of the feeding rack 5. The bottom end of the pressure rod 56 is fixedly provided with a connecting seat 57, which is located below the feeding rack 5. A spring is provided between the connecting seat 57 and the feeding rack 5. Here, the spring is a tension spring, which is used to provide an upward force to the connecting seat 57 so that it lifts up the sample bottle 6.

[0060] Both sides of the connecting seat 57 are movably provided with movable arms 58 via pins. One end of the movable arm 58 is movably provided with a support arm 59 via a pin, and the top end of the support arm 59 is fixed to the bottom end of the clamping plate 54. Under the action of centrifugal force, the sample bottle 6 applies pressure to the pressure seat 55 so that the connecting seat 57 moves away from the feeding rack 5. The connecting seat 57 drives the clamping plate 54 to move inward through the movable arm 58 and the support arm 59 so that it clamps the sample bottle 6.

[0061] The bottom end of the support arm 59 is movably connected to a connecting rod 591 via a pin. Both ends of the connecting rod 591 are fixedly provided with fixing plates 592, and the fixing plates 592 are fixedly provided to the bottom end of the feeding rack 5. The fixing plates 592 and the connecting rod 591 restrict the range of motion of the support arm 59. When the connecting seat 57 drives the bottom end of the movable arm 58 to move downward, the movable arm 58 drives the middle part of the support arm 59 to move downward, while the bottom end of the support arm 59 is restricted by the connecting rod 591 to flip, so as to drive the clamping plate 54 to move, thereby achieving the clamping of the sample bottle 6.

[0062] The sample bottle 6 has a detachable plug-in arrangement inside the feeding rack 5. The sample bottle 6 is used to store blood samples. In other embodiments, the sample bottle 6 can also be fixed by clamping, snapping or other means.

[0063] Sample bottle 6 is mounted on the outside of turntable 4 via feed rack 5. Power shaft 3 drives feed rack 5 and sample bottle 6 to rotate at high speed via turntable 4 to achieve separation of serum and plasma in blood within sample bottle 6.

[0064] The call module 7 is located on the outside of the main body 1 of the device. The call module 7 includes a timer controller, a speaker and a power supply. The call module 7 is used to send a call message to remind the user after the device has been started for a certain period of time. It should be noted that the timer controller, speaker and power supply in the call module 7 are all commercially available devices. The timer controller is connected to the motor through a wire, which can realize the timing and control of the motor at the same time, so as to facilitate the operation of the user.

[0065] When using a blood separation device with a call function in this embodiment, first open the main body 1 of the device and take the turntable 4 out of the processing cavity 2. Then, insert multiple sample bottles 6 containing blood samples into the feeding rack 5 until the bottom of the sample bottle 6 is inserted into the positioning sleeve 52. Then, put the turntable 4 into the processing cavity 2 and make the spline groove 32 in the middle of the turntable 4 cooperate with the spline shaft 31 to complete the connection between the turntable 4 and the power shaft 3.

[0066] Then close the cover of the main body 1 of the equipment and start the power motor. The power motor drives the power shaft 3 to rotate, the power shaft 3 drives the turntable 4 to rotate, the turntable 4 drives the feeding rack 5 to rotate, and the feeding rack 5 drives the sample bottle 6 to rotate. At this time, the sample bottle 6 and the feeding rack 5 swing under the action of centrifugal force, so that the sample bottle 6 in the vertical state flips to a horizontal state. The sample bottle 6 rotates at high speed in the horizontal state. The plasma and serum of the blood sample in the sample bottle 6 are separated under the action of centrifugal force. After the power motor rotates for a certain period of time, it stops. At this time, the sample bottle 6 and the feeding rack 5 lose the action of centrifugal force. At this time, the sample bottle 6 and the feeding rack 5 flip to a vertical state under the action of gravity. After the sample bottle 6 loses the centrifugal force, the force on the pressure seat 55 disappears. The pressure seat 55, the pressure rod 56 and the connecting seat 57 move upward under the action of the spring, so that the sample bottle 6 is lifted upward to facilitate the subsequent removal of the sample bottle 6. At this time, open the cover of the main body 1 of the equipment and take out the turntable 4 and the feeding rack 5 to remove the sample bottle 6.

[0067] During this process, the feeding rack 5 drives the connecting arm 51 to swing. The connecting arm 51 squeezes the extension rod 36 through the pressure plate 37, so that the extension rod 36 drives the limiting block 34 to slide in the through groove 35. After sliding, one end of the limiting block 34 is inserted into the limiting groove 33 to achieve the limiting between the turntable 4 and the power shaft 3, thereby preventing the turntable 4 and the power shaft 3 from separating due to high-speed rotation.

[0068] When the power motor is started, the timer controller in the call module 7 is also activated, causing the timer controller to start timing. After a certain time has elapsed, the timer controller controls the speaker to send out a call message, so as to facilitate the operation of the device by the staff.

[0069] Example 2

[0070] In this embodiment, a blood separation method using a blood separation device with a call function includes the following steps:

[0071] Step 1: Sample placement. Place the blood to be separated into sample bottle 6, and then place sample bottle 6 into multiple material racks 5. Then place material racks 5 onto the power shaft 3.

[0072] The sample bottle 6 is picked up and placed in the vertical position of the feeding rack 5 to facilitate the picking up and placing of the sample bottle 6.

[0073] Step 2, sample separation: The power motor inside the main body of the control device 1 drives the power shaft 3 to rotate. The power shaft 3 drives the sample bottle 6 to rotate at high speed through the turntable 4 and the feeding rack 5, so that the serum and plasma in the blood sample in the sample bottle 6 are separated under the action of centrifugal force. When the power motor is started, the timer controller in the call module 7 is pressed at the same time.

[0074] Step 3: Sample Removal. After the equipment has been running for a period of time, the speaker in the call module 7 will issue a call message and the motor will stop rotating. At this time, the feeding rack 5 can be removed and multiple sample bottles 6 can be removed respectively.

[0075] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
