Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to an intelligent blood plasma separator. Background Art

[0002] When separating plasma and red blood cells, separation equipment is needed. At present, some staff members use manual plasma separators or fully automatic component separators to separate the blood components in blood bags. Among them, manual plasma separators are small in size and low in cost, but they require personnel to supervise during the blood separation process, resulting in large manpower investment and low work efficiency. Otherwise, it is easy to squeeze red blood cells into the plasma bag, resulting in a decrease in separation effect. Fully automatic component separators have the advantages of good separation effect and high degree of automation, but they are expensive, the preparation cost of blood component separation is high, and they occupy a large area.

DETAILED DESCRIPTION

[0028] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0030] In the description of the utility model, if there is a word description such as "several", it means one or more, and the meaning of "more" is two or more. Greater than, less than, and more than are understood to exclude the number itself, and above, below, and within are understood to include the number itself. If there is a description of the first, second, and third, it is only used to distinguish the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] With the rapid development of science and technology in my country, the component department of the blood collection and supply industry has gradually adopted automated, intelligent and data-based instruments or equipment for all aspects of blood preparation. Among them, blood component separation is the most critical work link.

[0033] At present, manual separation clamps or fully automatic component separators are commonly used for blood component separation. Among them, the manual separation clamp uses a spring to drive the extrusion plate to squeeze the blood bag, and squeeze the upper plasma of the centrifuged blood bag into the empty plasma bag. Manual supervision is required during the entire separation process, which will consume a lot of manpower. Otherwise, it is easy to squeeze red blood cells into the plasma bag, resulting in a decrease in separation effect. Fully automatic component separators can realize automatic plasma separation without manual supervision. However, most of the fully automatic component separators are currently purchased through imports, and the cost is quite expensive. In addition, the preparation cost of blood component separation is quite high, which is not conducive to the use of medical units with large blood collection volumes, nor is it conducive to the use of medical units with small blood collection volumes.

[0034] Based on the above problems, the utility model provides an intelligent blood plasma separator, which can automatically separate plasma, PRP (platelet-rich plasma) and red blood cells in whole blood into corresponding empty blood bags. The whole process does not require manual supervision, which can reduce the intensity of manual labor. It can solve the problems of large footprint and high cost investment of traditional fully automatic component separators, so that blood collection and supply units can place more instruments, increase the quantity of plasma preparation, and improve the quality of plasma preparation.

[0035] Reference Figures 1 to 4 , several embodiments of the intelligent blood plasma separator of the utility model are given below.

[0036] like Figures 1 to 4As shown, the intelligent blood plasma separator provided according to the embodiment of the utility model can automatically complete the plasma separation work, has the advantages of small footprint, low cost and good separation effect, and can be used in medical units with large blood collection volume, and can also be used in medical units with small blood collection volume.

[0037] The intelligent blood pulping machine has a first direction, a second direction and an up-down direction, wherein the first direction is perpendicular to the second direction and the up-down direction, and the second direction is perpendicular to the up-down direction. In this embodiment, it is assumed that the first direction is the front-back direction and the second direction is the left-right direction.

[0038] The structure of the intelligent blood pulping machine includes an organism 100, a clamping plate 200, a bag hanging rod 710, a driving device, a first catheter clamp 520, a first sensor 820 and a controller.

[0039] The machine body 100 is provided with a clamping plate 200 and a bag hanging rod 710. The clamping plate 200 and the bag hanging rod 710 are both arranged on one side of the machine body 100 in the first direction, the lower end of the clamping plate 200 is hinged to the machine body 100, and the hinge axis of the clamping plate 200 extends along the second direction, and the clamping plate 200 can swing around its hinge axis. A squeezing area is defined between the clamping plate 200 and the machine body 100, and the staff can place the centrifuged blood bag in the squeezing area. The bag hanging rod 710 is fixedly connected to the machine body 100, and the bag hanging rod 710 is located above the squeezing area, and the staff can hang the blood bag on the bag hanging rod 710.

[0040] A support portion is provided at the lower end of the clamp 200, and the support portion is located on the surface of the clamp 200 close to the squeezing area. When the blood bag is placed in the squeezing area, the support portion can provide a certain support to the bottom of the blood bag. The support portion can be in a long strip shape and extend along the second direction. The support portion is fixedly connected to the clamp 200.

[0041] In this embodiment, the clamping plate 200 and the bag hanging rod 710 are located at the front side of the machine body 100, and the lower end of the clamping plate 200 can be mounted on the machine body 100 through the hinge 210, and the hinge axis between the clamping plate 200 and the machine body 100 extends in the left-right direction. The clamping plate 200 is a square plate. The bag hanging rod 710 is a round rod and extends in the front-back direction, and the rear end of the bag hanging rod 710 is fixedly connected to the machine body 100. Two bag hanging rods 710 are provided and are spaced apart in the left-right direction, so that the two round holes on the blood bag can be covered on the bag hanging rods 710.

[0042] A cavity is formed inside the body 100, and the cavity is located at the lower part of the body 100. Moreover, the body 100 is provided with a through hole 101, and the through hole 101 is connected to the cavity. The upper end of the through hole 101 passes through the body 100 and forms an opening structure, and the lower end of the through hole 101 passes through the body 100 and communicates with the cavity. It can be understood that the shape and size of the cavity can be set according to actual conditions, as long as it can accommodate the drive device. In this embodiment, the through hole 101 is a long strip hole and extends in the front-to-back direction. The body 100 can be made of, but not limited to, a metal material such as iron.

[0043] The structure of the driving device includes a linear driving mechanism 330 , a connecting block 320 and a connecting arm 310 .

[0044] The linear drive mechanism 330 and the connecting block 320 are both arranged in the cavity of the machine body 100, can be hidden in the machine body 100, and are not easily affected by the outside. The output end of the linear drive mechanism 330 is connected to the connecting block 320. When the linear drive mechanism 330 is running, the output end of the linear drive mechanism 330 can drive the connecting block 320 to move along the first direction. The linear drive mechanism 330 is fixedly connected to the machine body 100 through the first mounting frame 340. It can be understood that the linear drive mechanism 330 can be a linear drive device such as an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, a linear module, etc., which can drive the connecting block 320 to move linearly along the first direction.

[0045] In this embodiment, the linear drive mechanism 330 is a screw motor, which has a screw rod extending in the front-to-back direction, and the connecting block 320 is a nut seat, which is provided with a screw hole threadedly connected to the screw rod, and the nut seat can be installed on the machine body 100 through a slide rail and a slider pair, so that the nut seat and the machine body 100 are slidably connected in the front-to-back direction. The connecting arm 310 and the connecting block 320 are both made of metal materials such as iron.

[0046] The upper end of the connecting arm 310 is connected to the surface of the clamping plate 200 away from the extrusion area, the lower end of the connecting arm 310 passes through the through hole 101 and is hinged to the connecting block 320, and the hinge axis of the connecting arm 310 extends along the second direction. In this embodiment, the upper end of the connecting arm 310 is fixedly connected to the front side of the clamping plate 200 by bolts, and the lower end of the connecting arm 310 is hinged with a mounting seat, and the mounting seat is installed on the nut seat by bolts. The clamping plate 200 is provided with two hinges 210, and the two hinges 210 are symmetrical about the clamping plate 200. The connection between the connecting arm 310 and the clamping plate 200 is located in the middle of the two hinges 210. Specifically, the connecting arm 310 can be connected to the center position of the clamping plate 200.

[0047] It is understandable that when the linear drive mechanism 330 drives the connection block 320 to move forward, the connection arm 310 will rotate counterclockwise relative to the connection block 320, and drive the clamping plate 200 to rotate counterclockwise relative to the body 100, so that the clamping plate 200 can squeeze the blood bag located in the squeezing area. When the linear drive mechanism 330 drives the connection block 320 to move backward, the connection arm 310 will rotate clockwise relative to the connection block 320, and drive the clamping plate 200 to rotate clockwise relative to the body 100, so that the clamping plate 200 releases the squeezing effect on the blood bag and makes the upper end opening of the squeezing area larger, so that the staff can place the next centrifuged blood bag in the squeezing area.

[0048] The first catheter clamp 520 is installed on the body 100 and is disposed on the surface of the body 100. The first catheter clamp 520 can clamp the catheter between the blood bags and can control the catheter to be cut off or connected. The first catheter clamp 520 can be an electric proportional clamp valve. In this embodiment, the first catheter clamp 520 is disposed on the front side of the body 100.

[0049] The first sensor 820 is installed on the body 100 and disposed on the surface of the body 100. The first sensor 820 is used to detect the type of liquid flowing in the catheter. The first sensor 820 may be a color sensor or an infrared sensor capable of detecting red blood cells.

[0050] In this embodiment, the first sensor 820 is a color sensor that can identify red blood cells. When the first sensor 820 detects that red blood cells are flowing in the catheter, the first sensor 820 generates a detection signal. The first sensor 820 is disposed on the front side of the body 100 .

[0051] The controller is electrically connected to the first sensor 820 and the first catheter clamp 520, respectively, and the controller can control the opening and closing of the first catheter clamp 520 according to the detection of the first sensor 820. The controller can send a control signal to the first catheter clamp 520 according to the detection signal of the first sensor 820 to control the first catheter clamp 520 to close. It can be understood that the controller can be a 51 single chip microcomputer, a PLC controller, a main control board, etc.

[0052] In the intelligent blood plasma separation machine provided in the present embodiment, since the splint 200 and the bag hanging rod 710 are arranged on one side of the body 100 in the first direction, the splint 200 and the body 100 jointly define a squeezing area. Therefore, when the centrifuged blood bag is hung on the bag hanging rod 710 and the blood bag is located in the squeezing area, the driving device is activated to allow the splint 200 to move under the driving action of the driving device, so that the splint 200 automatically swings around the hinge axis between it and the body 100, and can exert a squeezing effect on the blood bag in the squeezing area, thereby expelling the uppermost layer of plasma through the catheter to the empty plasma bag.

[0053] During the whole plasma separation process, the type of liquid flowing in the catheter is monitored in real time by means of the first sensor 820. When the first sensor 820 detects that red blood cells are flowing in the catheter, the controller controls the first catheter clamp 520 to close, preventing the red blood cells from flowing into the plasma bag through the catheter, thereby achieving the purpose of automating the separation of plasma and improving the effect of blood component separation.

[0054] In the driving device structure, the linear driving mechanism 330 and the connecting block 320 are arranged in the cavity at the lower part of the body 100, and a connecting arm 310 is arranged between the connecting block 320 and the clamping plate 200, which can make full use of the lower space of the body 100 and provide an installation position and good protection for the driving device, thereby effectively reducing the footprint of the intelligent blood plasma separator, and more intelligent blood plasma separators can be placed in the blood collection and supply unit to prepare a larger amount of plasma.

[0055] Moreover, when the linear drive mechanism 330 drives the connection block 320 to move linearly in the first direction, the connection arm 310 moves linearly with the connection block 320 and swings around the hinge axis between the connection block 320 and the connection block 320, so as to drive the clamping plate 200 to swing around the hinge axis between the clamping plate 200 and the machine body 100 and squeeze the blood bag. Compared with the method of driving the hinge axis on the clamping plate 200 to realize the automatic swing of the clamping plate 200, the above-mentioned structural setting can reduce the driving force applied by the driving device to the clamping plate 200, thereby reducing the performance requirements of the linear drive mechanism 330 such as torque, and reducing the cost of the intelligent blood pulping machine.

[0056] The intelligent blood plasma separator provided in this embodiment can simultaneously meet the requirements of low cost, large-volume purchase and use, and fast separation speed, and can reduce manual labor intensity and improve the efficiency of plasma preparation.

[0057] In some embodiments, Figure 1 and Figure 4 As shown, the structure of the intelligent blood pulping machine also includes a control switch.

[0058] The control switch is disposed on the surface of the machine body 100, and the function of the control switch is to control the opening and closing of the linear drive mechanism 330. The control switch and the linear drive mechanism 330 are electrically connected to the controller respectively. The control switch can be disposed on the left side, the right side or the upper side of the clamping plate 200.

[0059] In this embodiment, the control switch may be a button 110. After the staff member presses the button 110, the controller receives the corresponding input command, and the controller sends a start signal to the linear drive mechanism 330 to operate the linear drive mechanism 330 and drive the clamping plate 200 to squeeze the blood bag to perform the pulping operation. When the linear drive mechanism 330 is operating, if the button 110 is pressed, the linear drive mechanism 330 will stop operating under the control signal of the controller.

[0060] It is understandable that after completing a blood separation operation, the controller can control the linear drive mechanism 330 to operate and drive the clamping plate 200 to swing in the opposite direction to release its squeezing effect on the blood bag. The setting of the control switch can achieve the purpose of completing the blood component separation work with one click through the mechanical button 110.

[0061] In some embodiments, Figure 1 and Figure 4 As shown, the structure of the intelligent blood pulping machine also includes a control panel. The function of the control panel is to set the operating parameters of the linear drive mechanism 330. The control panel is arranged on the surface of the machine body 100, and the control panel and the linear drive mechanism 330 are electrically connected to the controller respectively.

[0062] In this embodiment, the control panel is a touch screen 120, which is arranged above the clamp plate 200. The staff can click on the control panel to set operating parameters, process operations and blood separation information. It can be understood that the operating parameters of the linear drive mechanism 330 can be set through the control panel to control the torque and speed of the clamp plate 200, so that the separation is more accurate and the quality of blood component separation is improved.

[0063] In some embodiments, Figure 1 and Figure 4 As shown, the structure of the intelligent blood pulping machine also includes a hook rod 600. The first catheter clamp 520 and the first sensor 820 are both located above the bag hanging rod 710, and the hook rod 600 extends in the up-down direction and is disposed on the upper surface of the body 100.

[0064] It is understandable that the hook rod 600 and the body 100 can be detachably connected, and the hook rod 600 can be adjusted up and down on the body 100. The hook rod 600 includes a rod body and a hook, the lower end of the rod body is connected to the body 100, and the upper end of the rod body is provided with a hook, and the staff can hang the plasma bag on the hook.

[0065] Further, the body 100 is provided with a protective cover 130, which is detachably connected to the body 100, and is located on one side of the body 100 in the first direction, and a protective cavity is formed between the protective cover 130 and the body 100, and the first catheter clamp 520 and the first sensor 820 are arranged at intervals along the second direction and are disposed in the protective cavity. A through hole 131 is provided on the upper surface of the protective cover 130, and the through hole 131 extends to two opposite side surfaces of the protective cover 130 in the second direction, so that the catheter passes through the through hole 131 from top to bottom and is placed on the first sensor 820 and the first catheter clamp 520.

[0066] In this embodiment, the protective cover 130 is a rectangular parallelepiped, and the four corners are designed with arc transitions. The first sensor 820 is located on the left side of the first conduit clamp 520. The first sensor 820 and the first conduit clamp 520 are located above the clamp plate 200 and are arranged on the front side of the body 100. The control panel is located on the left side of the first sensor 820. The through hole 131 passes through the upper surface of the protective cover 130 and extends to the left and right sides of the protective cover 130.

[0067] Then, before starting the slurry separation work, the staff can pass the catheter from top to bottom through the through hole 131 and place it on the first sensor 820 and the first catheter clamp 520, so that the first catheter clamp 520 can clamp or release the catheter, and the first sensor 820 can detect the type of liquid flowing in the catheter in real time. At this time, the first sensor 820 and the first catheter clamp 520 can support the catheter.

[0068] It can be understood that the protection cover 130 can not only protect the first sensor 820 and the first catheter clamp 520, but also have a decorative effect.

[0069] In some embodiments, Figure 1 and Figure 4 As shown, the structure of the intelligent blood pulping machine also includes a second sensor 810. The machine body 100 is provided with a detection station, which is located on the surface of the machine body 100 close to the squeezing area. The second sensor 810 is arranged opposite to the detection station. The function of the second sensor 810 is to detect the red blood cell level of the blood bag in the squeezing area.

[0070] The controller is electrically connected to the second sensor 810 and the first catheter clamp 520 respectively. The controller can also be used to control the clamping force of the first catheter clamp 520 to decrease according to the increase of the red blood cell level.

[0071] It is understandable that the body 100 may be provided with a transparent plate at the detection station, or may be provided with a detection hole 102, so that the second sensor 810 can monitor the red blood cell level of the blood bag in real time. The second sensor 810 is a multi-point infrared detection sensor.

[0072] In this embodiment, the detection station is provided with a plurality of detection holes 102, which are circular holes, and are arranged at intervals along the up-down direction of the body 100 and along the left-right direction of the body 100. The second sensor 810 uses an array infrared detection board, and the second sensor 810 is arranged corresponding to the plurality of detection holes 102. Therefore, as the squeezing time goes by, the red blood cell level in the blood bag will rise, which can be detected in real time by the second sensor 810. As the red blood cell level continues to rise, the red blood cells are easy to flow into the catheter. At this time, the controller can control the clamping force of the first catheter clamp 520, control the flow rate of the catheter, and effectively prevent the red blood cells from flowing into the plasma bag.

[0073] In some embodiments, Figure 1 and Figure 4 As shown, the structure of the intelligent blood pulping machine also includes a second catheter clamp 510. The second catheter clamp 510 is installed on the body 100 and is arranged on the upper surface of the body 100. The second catheter clamp 510 is used to clamp the catheter between the hook rod 600 and the first catheter clamp 520. The second catheter clamp 510 is an electric clamp valve that can control the cutoff and conduction of the catheter. The second catheter clamp 510 is electrically connected to the controller, and the controller can control the action of the second catheter clamp 510.

The breaking rod 720 can be a round rod.

[0075] In this embodiment, the diameter of the breaking rod 720 is larger than that of the bag hanging rod 710, and the distance between the two breaking rods 720 is larger than the distance between the two bag hanging rods 710. When the blood bag is hung on the bag hanging rod 710, the staff can grab the catheter on the blood bag and swing it to the left and right, and the plug rod in the catheter will be broken, so that the liquid can flow in both directions between the catheter and the blood bag; then, the staff can start the automatic blood separation by clicking the control switch. This setting allows the staff to carry out blood component separation more conveniently when using the intelligent blood separation machine.

[0076] The two breaking rods 720 and the two bag hanging rods 710 are all arranged on the mounting block, so that the mounting block, the breaking rods 720 and the bag hanging rods 710 form a rod assembly 700, and the mounting block is fixed to the body 100 by bolts, and the front side of the body 100 is provided with corresponding circular holes for the breaking rods 720 and the bag hanging rods 710 to pass through.

The weighing module 430 is connected to the bracket 420. Specifically, the weighing module 430 is fixedly connected to the center position of the bracket 420, and the weighing module 430 is fixedly connected to the body 100 through the second mounting bracket 440. The weighing module 430 and the display screen are respectively electrically connected to the controller.

[0079] It is understandable that the function of the bracket 420 is to connect the weighing module 430 and the weighing pan 410. The weighing module 430 includes a weighing sensor, a mounting plate, etc. The second mounting bracket 440 firmly fixes the weighing module 430 in the machine body 100. The display screen can clearly display the weighing data. In this embodiment, the display screen is integrated into the control panel.
