Detailed implementation manners

[0033] For the convenience of understanding the present invention, the specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings of the specification.

[0034] Unless otherwise specified or defined, the "first, second..." used herein is only for differentiating names and does not represent a specific quantity or order.

[0035] Unless otherwise specified or defined, the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] It should be noted that "fixed to" and "connected to" herein can be directly fixed or connected to an element, or indirectly fixed or connected to an element.

[0037] An embodiment of the present invention provides an intelligent blood collection instrument 100. As Figures 1 to 6 shown, the intelligent blood collection instrument 100 includes an operation table 1, a limiting mechanism 2, and a grasping mechanism 3; an accommodation groove 11 is provided on the operation table 1. The accommodation groove 11 is used to place the arm of the person to be blood collected.

[0038] The limiting mechanism 2 includes a first moving device 21, a mounting frame 22, a winding device 23, and a developing device 24; the first moving device 21 is disposed on the operation table 1, and the output end of the first moving device 21 is connected to the mounting frame 22 and drives the mounting frame 22 to reciprocate along the extending direction of the accommodation groove 11. It should be noted that the extending direction of the accommodation groove 11 refers to the extending direction of the length direction of the accommodation groove 11, that is, the length extending direction when the arm of the person to be blood collected is placed in the accommodation groove 11. When the first moving device 21 drives the mounting frame 22 to reciprocate along the length direction of the accommodation groove 11 to different positions of the accommodation groove 11, the mounting frame 22 can adapt to adjust its own position to different positions of the arm of the person to be blood collected. The winding device 23 and the developing device 24 are both disposed on the mounting frame 22. The winding device 23 can form a tightened state or a loosened state to fix or loosen the arm; the developing device 24 is used to identify and locate the blood collection position of the arm. It can be understood that since the persons to be blood collected have different age groups, the arm lengths and sizes of the persons to be blood collected are quite different. When the arm of the person to be blood collected is placed in the accommodation groove 11 and extends into the winding device 23, the winding device 23 is in a loosened state at this time. Subsequently, the developing device 24 will identify and analyze the arm of the person to be blood collected placed in the accommodation groove 11 to obtain the blood collection position of the arm of the person to be blood collected. Subsequently, the first moving device 21 is controlled to drive the mounting frame 22 to move along the extending direction of the accommodation groove 11 so that the winding device 23 on the mounting frame 22 moves to the upper section of the blood collection position of the arm of the person to be blood collected. Subsequently, the winding device 23 forms a tightened state to tighten the arm, so that the veins on the arm bulge and are exposed for subsequent blood collection operations.

[0039] The grasping mechanism 3 includes a second moving device 31, a grasping member 32, and a vision module. The second moving device 31 is connected to the grasping member 32 and drives the grasping member 32 to move in the space on the operation table 1. Among them, the vision module is used to screen the area below the grasping member 32, so that the grasping member 32 can accurately reach the preset blood collection position under the drive of the second moving device 31 for blood collection. The grasping member 32 is used to grasp the blood collection device and pierce the blood collection device into the blood vessel of the person to be blood collected for blood collection operation. It should be noted that the intelligent blood collection instrument 100 also includes conventional components such as a control system and a power supply to realize the automatic control and operation of the intelligent blood collection instrument 100.

[0040] Specifically, the control method based on the intelligent blood collection instrument 100 includes the following steps:

[0041] When the arm of the person to be blood-collected is placed in the placement slot 11 and extends into the winding device 23, the winding device 23 is in a loose state;

[0042] The developing device 24 identifies and analyzes the arm of the person to be blood drawn placed in the placement tank 11 to obtain the blood collection position and information of the arm of the person to be blood drawn;

[0043] Based on the obtained blood sampling position and information, the first moving device 21 is controlled to drive the mounting frame 22 to move along the extension direction of the placement slot 11 so that the winding device 23 on the mounting frame 22 moves to the upper part of the blood sampling position on the arm of the person to be blood drawn. The winding device 23 is now in a tightened state and fixes the upper part of the arm;

[0044] The grabbing part 32 grabs the blood collection device, locates the position of the arm through the visual module, and controls the second moving device 31 to move the grabbing part 32 to the position of the arm according to the position of the arm. Then the grabbing part 32 drives the blood collection device to penetrate the arm for blood collection operation according to the blood collection position and information.

[0045] In summary, the intelligent blood collection instrument 100 identifies and analyzes the arm of the person to be blooded by setting a developing device 24 to obtain the blood collection position and information of the arm of the person to be blooded. The first moving device 21 can drive the winding device 23 to move to the upper part of the blood collection position of the arm of the person to be blooded to fix the upper part of the arm, so that the tendons and veins on the arm are expanded and exposed to facilitate subsequent blood collection operations. The visual module is used to identify the area below the grabbing part 32, so that the grabbing part 32 can accurately reach the preset blood collection position for blood collection operation under the drive of the second moving device 31. Therefore, through the cooperation of the above-mentioned various mechanical components, automatic blood collection operation can be realized for the person to be blooded, without the need for manual assistance, and can adapt to blood collection operations on the arms of different people.

[0046] In some embodiments, as Figure 2 and Figure 4As shown, the first mobile device 21 includes a first driving device 211 and a slide rail 212; on opposite sides of the operation table 1 corresponding to the placement groove 11, sliding grooves 213 are respectively provided, and the slide rail 212 is laid on both of the two sliding grooves 213. The mounting bracket 22 is slidably disposed on the slide rail 212, and the output end of the first driving device 211 is connected to the mounting bracket 22 and drives the mounting bracket 22 to reciprocate along the slide rail 212. It can be understood that by providing the first driving device 211 and the slide rail 212 and making the mounting bracket 22 slidable on the slide rail 212, the mounting bracket 22 can move smoothly and smoothly in the extending direction of the placement groove 11, so that the winding device 23 can be adjusted to a suitable position according to the blood collection position of the arm of the person to be blood collected. Moreover, since the slide rail 212 is disposed at the sliding grooves 213 on both sides of the placement groove 11, it can avoid affecting the comfort of placing the arm in the placement groove 11. The first driving device 211 can be a device such as a lead screw stepping motor that can drive the mounting bracket 22 to reciprocate, and no special limitation is made here.

[0047] In some embodiments, as Figure 4 and Figure 5 shown, the winding device 23 includes a winding belt 231, two second driving devices 232 and two winding shafts 233. The two winding shafts 233 are rotatably disposed on the mounting bracket 22 and are located on opposite sides of the placement groove 11. The output ends of the two second driving devices 232 are respectively connected to the two winding shafts 233 and drive the winding shafts 233 to rotate. Both of the two winding shafts 233 are connected to the winding belt 231 and wind or unwind the winding belt 231. The structure of the winding belt 231 at the position between the two winding shafts 233 is an arc-shaped structure, and the space between the arc-shaped structure and the mounting bracket 22 forms a winding cavity. It can be understood that by providing two winding shafts 233 to control the winding or unwinding of the winding belt 231, the winding belt 231 can quickly tighten or loosen the arm of the person to be blood collected. In addition, the position of the winding belt 231 between the two winding shafts 233 is an elastic belt, so that the structure of the winding belt 231 at the position between the two winding shafts 233 is in an arc-shaped structure in the normal state, which is convenient for the person to be blood collected to extend into the winding cavity for tightening operation. In addition, it should be noted that a pressure sensor can be provided at the position of the winding belt 231 between the two winding shafts 233. When the pressure sensor senses that the tightening pressure between the winding belt 231 and the arm exceeds the preset pressure, the winding shaft 233 stops continuing to wind, so that the winding cavity formed by the winding belt 231 can adapt to the arm of the person to be blood collected, achieving the effect of being able to tighten the arm while having appropriate comfort and avoiding excessive tightening from affecting the blood collection operation and comfort. The second driving device 232 can be a device such as a stepping motor that can drive the winding shaft 233 to rotate, and no special limitation is made here.

[0048] Specifically, in this embodiment, as Figure 4 shown, the mounting bracket 22 is provided with fixing grooves on opposite sides of the placement groove 11, and a communication channel connecting the fixing groove and the placement groove 11 is provided at the bottom of the fixing groove of the mounting bracket 22 and close to the side of the placement groove 11. The communication channel is used for the winding belt 231 to pass through, so that the winding belt 231 can cover the upper area of the placement groove 11 to tighten the arm.

[0049] In some embodiments, as Figure 2 and Figure 4 shown, an elastic gripping member 12 is provided at a position of the placement groove 11 close to its inner end. It should be noted that the placement groove 11 is formed by recessing from one side of the operation table 1 facing the blood donor to the opposite side, and the end of the placement groove 11 away from the blood donor is the inner end. The elastic force direction of the elastic gripping member 12 is consistent with the extending direction of the placement groove 11, and the elastic gripping member 12 is disposed opposite to the winding device 23. It can be understood that the elastic gripping member 12 is used for the blood donor to grip tightly, and cooperates with the winding device 23 to make the vein of the blood donor fully appear. The elastic action of the elastic gripping member 12 facilitates the adaptation of the arms of different lengths of different blood donors to grip tightly.

[0050] In some embodiments, as Figure 4 shown, the elastic gripping member 12 includes an elastic telescopic member 121 and a gripping portion 122. A guiding groove 123 is provided on the groove side wall of the operation table 1 corresponding to the placement groove 11. The elastic telescopic member 121 is disposed in the guiding groove 123. The gripping portion 122 is connected to the elastic telescopic member 121, and the gripping portion 122 extends into the placement groove 11. Among them, by providing the guiding groove 123, the guiding groove 123 can guide the elastic movement of the elastic telescopic member 121, so that the elastic telescopic member 121 reciprocally expands and contracts along the extending direction of the guiding groove 123, driving the gripping portion 122 to reciprocally move in the extending direction of the guiding groove 123, and improving the movement stability of the gripping portion 122. Among them, the elastic telescopic member 121 can be an elastic component such as a spring, and no special limitation is made here.

[0051] In some embodiments, the developing device 24 includes a vein imager, an infrared camera, and an ultrasound probe, all of which are disposed on the mounting bracket 22; the vein imager is used to obtain an image of the vein distribution of the arm, the infrared camera is used to collect an infrared image of the blood vessels of the arm, and the ultrasound probe is used to obtain the depth of the vein blood vessels on the arm. Among them, the vein imager can scan the arm to irradiate an image of the vein distribution of the arm. The infrared camera is used to collect an infrared image of the blood vessels of the user's arm. Among them, the infrared image of the blood vessels includes a first left-viewpoint infrared image of the blood vessels and a first right-viewpoint infrared image of the blood vessels at the same part of the skin tissue; the thickest vein blood vessel is identified based on the infrared image of the blood vessels, and a blood collection point is identified among the thickest vein blood vessels, and the direction angle information of the blood vessel center line at the blood collection point is obtained according to the puncture direction. The ultrasound probe can collect a depth image of the thickest vein blood vessel, and then obtain the central depth information of the vein blood vessel based on the depth image, so as to determine the blood collection position and information of the arm, facilitating the subsequent adjustment of the position of the winding device 23 and the blood collection operation of the grasping mechanism 3.

[0052] In some embodiments, a protective pad is laid on the bottom of the placement groove 11. The protective pad can increase the comfort of the blood donor when stretching the arm into the placement groove 11.

[0053] In some embodiments, as Figure 4 and Figure 5 shown, the intelligent blood collection instrument 100 further includes a spraying mechanism 6. The spraying mechanism 6 includes a placement rack 61, a pump body 62, and a nozzle 63; the placement rack 61 is disposed on the mounting bracket 22. The placement rack 61 has a placement position for placing an alcohol bottle. The pump body 62 and the nozzle 63 are both disposed on the placement rack 61, and the nozzle 63 is connected to the alcohol bottle through a conduit. The pump body 62 is disposed at the conduit. Specifically, the pump body 62 is fixedly provided on the outer wall of one side of the placement rack 61. The pump body 62 is a micro water pump, which can pump the alcohol inside the alcohol bottle into the nozzle 63. The nozzle 63 is an atomizing nozzle, which can spray alcohol to disinfect the arm of the blood donor to avoid infection.

[0054] In some embodiments, as Figure 1 shown, the intelligent blood collection instrument 100 further includes a box body 4. The operation table 1 is disposed on the box body 4. A support plate device 41 extending outside the box body 4 is provided below the operation table 1 on the box body 4, and the support plate device 41 can move up and down relative to the box body 4. It can be understood that when the blood donor performs a blood collection operation, he can sit on the support plate device 41. The blood donor can adaptively adjust the height of the support plate device 41 according to his own position, so that the position of the blood donor is adjusted to a suitable position, facilitating special groups such as children and the elderly with inconvenient legs and feet to also be able to adapt to use the intelligent blood collection instrument 100 for blood collection.

[0055] In some embodiments, asFigure 1 As shown, the pallet device 41 includes a third driving device 411 and a pallet body 412. The box body 4 is located below the operation table 1 and is provided with a placement groove 42. The third driving device 411 is arranged in the placement groove 42. The output end of the third driving device 411 is connected to the pallet body 412 and drives the pallet body 412 to move up and down. The pallet body 412 is in an L-shaped structure. Specifically, the third driving device 411 includes a screw rod stepping motor and a connecting plate. The screw rod stepping motor is vertically arranged in the placement groove 42, and the output end of the screw rod stepping motor is connected to the pallet body 412 through the connecting plate. The screw rod stepping motor drives the pallet body 412 to move up and down in the vertical direction. The pallet body 412 is horizontally arranged to facilitate the blood donor to sit down. Specifically, in this embodiment, there are two screw rod stepping motors, and the two screw rod stepping motors are arranged in parallel and are both connected to the connecting plate to improve the driving force and driving stability. Further, a curtain 44 is hung at the notch of the placement groove 42 of the box body 4. The curtain 44 is used to shield the third driving device 411 to prevent it from being accidentally touched and injured by the blood donor.

[0056] In some embodiments, such as Figure 6As shown, the intelligent blood collection instrument 100 further includes a storage box 5 provided on the operation table 1. The storage box 5 includes a box body 51, a partition plate 52, an elastic support member 53, and a top plate 54. A plurality of partition plates 52 are provided, and the plurality of partition plates 52 are vertically inserted into the box body 51 to divide the internal space of the box body 51 into a plurality of storage slots. The bottom of each storage slot is provided with the top plate 54, and the elastic support member 53 is provided between the top plate 54 and the bottom of the box body 51. Among them, each storage slot of the box body 51 is used to place a blood collection device, and the blood collection device is an existing sampler integrated with a needle and a sampling tube. By stacking a plurality of blood collection devices in the storage slot, it is convenient for the grasping member 32 to continuously grasp the blood collection device for continuous blood collection operations. In addition, by providing an elastic support member 53 such as a spring and other components with elastic properties at the bottom of the storage slot, and providing a top plate 54 on the elastic support member 53, after the previous blood collection device is taken away, the elastic support member 53 can push up the top plate 54 to drive the next sampling tube to fill the space of the taken-away previous sampling tube, facilitating the grasping member 32 to continuously grasp the blood collection device. Specifically, the elastic support member 53 can be a spring, and the elastic force of the spring is calculated. For example, if 5 blood collection devices are placed in each storage slot, then when the spring is compressed to the minimum state, each time a blood collection device is taken away, the spring rises by a preset height to drive the next blood collection device to fill the space of the taken-away previous blood collection device. When all the blood collection devices are taken away, the spring returns to its original length, and the original length of the spring just ensures that it will not push out the top plate 54 on which the blood collection device is placed. Among them, a plurality of such elastic support members 53 can be provided in each storage slot, and the number thereof is set according to the specific required elastic support force, which is not particularly limited here, and each elastic support member 53 is dispersedly arranged at the bottom of the storage slot to stably support the top plate 54. Specifically, in this embodiment, three elastic support members 53 are provided, and the three elastic support members 53 are evenly arranged at the bottom of the storage slot.

[0057] In some embodiments, the grasping member 32 can be a manipulator, which can realize functions such as grasping and angle transformation, facilitating the grasping of the blood collection device and performing the acupuncture blood collection operation.

[0058] In some embodiments, as Figure 1 shown, an operation display module 7 is further provided above the operation table 1 of the box body 4. The operation display module 7 can start the intelligent blood collection instrument 100, and then log in the information by scanning the code with a mobile phone or placing the ID card on the operation display module 7 to enter the information of the person to be blood collected. In addition, the operation display module 7 can also perform operations and selections of other conventional functions, which are not particularly limited here.

[0059] In some embodiments, as Figure 3As shown, on the side of the box body 4 away from the pallet device 41, a box door 43 is installed through a hinge, and a handle is installed on one side of the box door 43. The handle facilitates opening the box door 43 for maintenance and adding consumables, etc.

[0060] In some embodiments, the second moving device 31 is a three-axis motion platform. Specifically, the three-axis motion platform is a motion platform that can move in the X-axis direction, Y-axis direction, and Z-axis direction to achieve the purpose of moving in three-dimensional space. The three-axis motion platform drives the grasping member 32 and the vision module to move in the X-axis, Y-axis, and Z-axis directions, thereby driving the grasping member 32 and the vision module to move arbitrarily in the operation table 1 area of the box body 4 to grasp blood collection tubes and perform blood collection operations.

[0061] The following will briefly describe a control method based on the intelligent blood collection instrument 100 in an implementation, including the following steps:

[0062] The operation display module 7 identifies and enters the information of the person to be blood collected.

[0063] When the arm of the person to be blood collected is placed in the placement groove 11 and extends into the winding cavity of the winding belt 231, at this time, the winding belt 231 is in an arc-shaped loose state.

[0064] The developing device 24 identifies and analyzes the arm of the person to be blood collected placed in the placement groove 11 to obtain the blood collection position and information of the arm of the person to be blood collected.
