Description

Technical Field

[0001] The present invention relates to the technical field of blood sampling, and particularly to an automated blood sample collection device for ankylosing spondylitis patients. Background Art

[0002] An automated blood collection robot is a high-tech medical device that combines machine vision, biometric technology, and intelligent navigation control technology, etc., and can automate the entire process of blood collection.

[0003] Ankylosing spondylitis is a chronic inflammatory disease that mainly affects the spine and peripheral joints. As the disease progresses, the inflammation is not only limited to the spine but may also spread to more parts. When the inflammation affects the wrist and finger joints, the patient's finger flexion function is limited and it is difficult to complete the fist clenching action. Fist clenching is a key step in filling the vein before blood collection. Through the active contraction of the hand muscles, it can effectively squeeze the vein, reduce blood reflux, and make the blood vessels dilate more significantly, facilitating needle puncture. If the patient's fingers cannot bend normally due to factors such as joint stiffness, synovial hyperplasia, and joint cavity stenosis, the effect of vein filling will be affected, making it difficult to visualize the blood vessels and increasing the difficulty of blood collection. In an automated blood collection robot, the system defaults that the patient can independently complete the fist clenching action to ensure that the blood vessel state meets the blood collection requirements. However, for patients who cannot clench their fists, the blood vessels may remain collapsed, resulting in blood collection failure or difficult puncture, affecting the success rate and stability of blood collection.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides an automatic blood sample collection device for ankylosing spondylitis, having the following beneficial effects:

[0018] 1. For this automatic blood sample collection device for ankylosing spondylitis, with the setting of the fist clenching mechanism, when the flexible glove is subjected to an external force, it bends in a predetermined direction. When the bellows is pushed by high-pressure air to elongate, multiple triangular prism grooves on the flexible glove will synchronously deform along the arrangement direction, causing the overall glove to bend inward, simulating the natural flexion movement of the fingers, thereby driving the palm of the ankylosing spondylitis patient to complete the clenching action, making the veins more obvious, facilitating accurate puncture, and improving the blood collection success rate.

[0019] 2. For this automatic blood sample collection device for ankylosing spondylitis, with the setting of the air blowing mechanism, it promotes air to flow into the air blowing mechanism. The air blows towards the hand in a circumferential array direction through the obliquely arranged air jet ports, warming the patient's hand. At the same time, the hand temperature is increased through the heating device, promoting blood vessel dilation and enhancing the visibility of the veins.

[0020] 3. For this automatic blood sample collection device for ankylosing spondylitis, with the setting of the protection mechanism, when the high-pressure air pressure in the bellows and the positioning hollow block is too high, the high-pressure air pushes open the sealing disc through the through hole on the hollow connecting bar. This design ensures that when the system pressure is too high, excess gas can be released in a timely manner, avoiding equipment damage caused by excessive pressure and discomfort to the patient.

Detailed implementation manners

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the protection scope of the present invention.

[0035] Please refer to Figure 1 - Figure 12 , an automated blood sample collection device for ankylosing spondylitis, comprising: a body 1, serving as a support structure for the entire device, accommodating all internal components, and providing a stable working environment; a control panel 2, provided on the body 1, for controlling the device, adjusting parameters such as the blood collection process, fist clenching force, temperature, etc., for the user to operate; an entrance 3, opened on one side of the body 1 for the hand to reach in; a collection mechanism 4, arranged inside the body 1 for blood collection; a fist clenching mechanism 5, arranged inside the body 1, for assisting the patient to complete the fist clenching action, helping the veins to fill, making the blood vessels more obvious, and improving the blood collection success rate, applicable to patients who are unable to clench their fists independently due to ankylosing spondylitis; a blowing mechanism 6, arranged on the fist clenching mechanism 5, for providing warm air flow, increasing the hand temperature, promoting blood vessel dilation, increasing blood flow, thereby improving vein visibility and the blood collection success rate; a protection mechanism 7, arranged on the fist clenching mechanism 5, for preventing the fist clenching mechanism 5 from applying excessive assisting force, protecting the patient's hand from excessive squeezing, and ensuring a safe and comfortable blood collection process.

[0036] The blood collection mechanism 4 includes: a driving shaft 41, which is fixedly connected to the inner wall of the body 1 to provide stable support and serves as the lifting center of the entire blood collection mechanism 4. At the bottom of the driving shaft 41, there is an electric universal rotating member 42. At the bottom of the electric universal rotating member 42, there is a puncture device 43. A puncture head 44 is provided on the puncture device 43. The puncture device 43 is used to perform the puncture operation to ensure that the puncture head 44 can accurately enter the target vein. The electric universal rotating member 42 is used to control the multi-angle adjustment of the puncture device 43, so that the puncture device 43 can perform precise positioning according to the blood vessel position information obtained by the recognition device 45. An identification device 45 is provided on the outer wall of the driving shaft 41. The identification device 45 is used for downward visual recognition of the vein position. By obtaining the venous image of the patient's hand, analyzing the vein trend and the optimal puncture point through an image processing algorithm, and transmitting this information to the electric universal rotating member 42 to adjust the angle and position of the puncture device 43 to ensure precise puncture. The identification device 45 first performs vein identification, obtains the coordinate information of the vein position, and transmits it to the control system. The control system adjusts the angle of the electric universal rotating member 42 according to the recognition data, so that the puncture device 43 accurately aligns with the target vein. After the adjustment is completed, the puncture device 43 is activated, and the puncture head 44 slowly descends and punctures into the blood vessel to ensure an appropriate puncture depth, and then blood extraction is performed. During the whole process, the driving shaft 41 provides structural support to ensure the stable operation of each component. The identification device 45 continuously monitors the blood vessel state to avoid puncture failure caused by blood vessel movement or collapse.

[0037] The fist clenching mechanism 5 includes: a main telescopic motor 51, which is fixedly connected to the inner wall of the body 1. The output shaft of the main telescopic motor 51 is fixedly connected with an annular handle 52, and a fixing ring 53 is fixedly connected to the annular handle 52. When the control system issues an instruction, the main telescopic motor 51 drives the annular handle 52 to expand and contract by adjusting the movement of the output shaft. The bottom of the fixing ring 53 is fixedly connected with a flexible glove 54. A high-pressure air output device 55 is fixedly connected to the inner wall of the body 1. The high-pressure air output device 55 is used to connect to an air compressor and output high-pressure air internally. A first high-pressure connecting pipe 56 is arranged on the high-pressure air output device 55. One end of the first high-pressure connecting pipe 56 is fixedly connected to the high-pressure air output device 55, and the other end of the first high-pressure connecting pipe 56 is fixedly connected with a first electromagnetic valve 57. The outer wall of the first electromagnetic valve 57 is fixedly connected with a hollow connecting strip 58. The high-pressure air output device 55 is connected to the flexible glove 54 through the first high-pressure connecting pipe 56 and the first electromagnetic valve 57. The hollow connecting strip 58 is fixedly connected to the outer wall of the flexible glove 54. A corrugated pipe 59 is fixedly connected to the hollow connecting strip 58, and a positioning hollow block 510 is fixedly connected to the corrugated pipe 59. There are several positioning hollow blocks 510, and the positioning hollow blocks 510 are arranged in an array. A triangular prism groove is arranged at the top of the flexible glove 54, and the triangular prism grooves on the flexible glove 54 are arranged in an array. When the first electromagnetic valve 57 is opened, high-pressure air enters the corrugated pipe 59, causing the corrugated pipe 59 to elongate and undergo axial extension. This extension generates a certain traction force on the hollow connecting strip 58 and the positioning hollow block 510. Since the top of the flexible glove 54 is provided with triangular prism grooves and the triangular prism grooves are arranged in an array, these groove structures form local stress concentration areas, causing the flexible glove 54 to bend in a predetermined direction when subjected to an external force. When the corrugated pipe 59 is pushed by high-pressure air to elongate, multiple triangular prism grooves on the flexible glove 54 will deform synchronously along the arrangement direction, causing the glove as a whole to bend inward, simulating the natural flexion movement of the fingers, so as to drive the palm of the ankylosing spondylitis patient to complete the clenching action. Thumb placement positions are provided on both sides of the flexible glove 54. Different patients may be accustomed to using their left or right hand for blood collection operations. The provision of bilateral thumb placement positions can be compatible with both left and right hands, improving the versatility of the device and avoiding restricting the hand placement method of users due to the design of a single-sided placement position.

[0038] The air blowing mechanism 6 includes a second electromagnetic valve 61. The second electromagnetic valve 61 is fixedly connected to the positioning hollow block 510 on the side farthest from the first electromagnetic valve 57. A second high-pressure connecting pipe 62 is provided on the second electromagnetic valve 61. The second electromagnetic valve 61 controls the air flow by controlling the opening and closing of the air flow, and controls the air flow direction to the second high-pressure connecting pipe 62. Through the opening and closing of the second electromagnetic valve 61, the air flow can be controllably transmitted to the fixed hollow block 63. One end of the second high-pressure connecting pipe 62 is fixedly connected to the second electromagnetic valve 61, and the other end of the second high-pressure connecting pipe 62 is fixedly connected to a fixed hollow block 63. The fixed hollow block 63 is fixedly connected to the annular handle 52. An outer wall of the fixed hollow block 63 is rotatably connected to a connecting disc block 64. An inclined air jet port 65 is fixedly connected to an inner wall of the connecting disc block 64. The inclined air jet ports 65 are arranged in a circumferential array. The high-pressure air in the fixed hollow block 63 is discharged through the connecting disc block 64 and the inclined air jet ports 65. When the inclined air jet ports 65 jet air, they will be driven by the reaction force to drive the connecting disc block 64 to rotate, so that the inclined air jet ports 65 rotate and jet air, and the direction and injection angle of the air flow will change, so that the air is evenly distributed to each part in the flexible glove 54. A heating device 66 is fixedly connected to an inner wall of the fixed hollow block 63. By heating the air on the inner wall of the fixed hollow block 63, hot air is provided to help increase the temperature of the patient's hand, thereby improving blood circulation and prompting the veins to become more prominent. This helps to increase the visibility of the veins and further improves the success rate of blood collection; when the system receives the instruction to start blood collection, the second electromagnetic valve 61 is activated, allowing high-pressure air to be transmitted through the second high-pressure connecting pipe 62 to the fixed hollow block 63, and pushing the air to flow into the air blowing mechanism 6. The air blows towards the hand in a circumferential array direction through the inclined air jet ports 65, warming the patient's hand, and at the same time increasing the hand temperature through the heating device 66, promoting blood vessel dilation and enhancing the visibility of the veins. In addition, the inclined air jet ports 65 ensure uniform air flow distribution, help the glove to expand, simulate the fist clenching action of the hand, and ultimately help to complete vein filling and prepare for blood collection. During this process, the air in the corrugated pipe 59 and the positioning hollow block 510 is output, and at this time the flexible glove 54 will not be curled. Until the patient's arm is heated for a period of time, the second electromagnetic valve 61 is closed, and then there is enough high-pressure air in the fist clenching mechanism 5 to clench the fist, ensuring that after the patient's hand has been heated to a sufficient temperature, there is enough high-pressure air in the fist clenching mechanism 5 to assist in clenching the fist. This design not only ensures the comfort of the hand, but also optimizes blood flow and vein filling, making the blood collection process smoother. The heating device 66 includes a heating plate 661. The heating plate 661 is fixedly connected to the inner wall of the fixed hollow block 63. A temperature controller 662 is fixedly connected to the heating plate 661. A temperature sensor 663 is fixedly connected to the temperature controller 662. The heating plate 661, as the core component of the heating device 66, is responsible for converting the input electrical energy into heat energy. The temperature controller 662 is mainly responsible for adjusting the heat output by the heating plate 661 to ensure that the temperature remains within the set range.The temperature controller 662 can adjust the power of the heating plate 661 in real time according to the temperature signal feedback by the temperature sensor 663, avoiding overheating or too low temperature, and ensuring the safety and comfort of the hand heating process.

[0039] The protection mechanism 7 includes a through hole 71 which is arranged on the inner wall of the hollow connecting bar 58. A sealing frame 72 is fixedly connected to the outer wall of the hollow connecting bar 58. A whistle 73 is fixedly connected to the sealing frame 72. A control motor 74 for controlling the expansion and contraction is fixedly connected to the outer wall of the hollow connecting bar 58. An output shaft of the control motor 74 is fixedly connected with a pressure sensor 75. A connecting block 77 is fixedly connected to the outer wall of the pressure sensor 75. A compression spring 78 is arranged on the outer wall of the connecting block 77. One end of the compression spring 78 is fixedly connected to the connecting block 77, and the other end of the compression spring 78 is fixedly connected with a sealing disc 79. A guide rod 710 is fixedly connected to the outer wall of the sealing disc 79, and the outer wall of the guide rod 710 is slidably connected to the inner wall of the connecting block 77. A pressure controller 76 is fixedly connected to the control motor 74, and the pressure controller 76 is electrically connected to the pressure sensor 75. When the high-pressure air pressure in the corrugated pipe 59 and the positioning hollow block 510 is too high, the high-pressure air pushes open the sealing disc 79 through the through hole 71 on the hollow connecting bar 58. This design ensures that when the system pressure is too high, the excess gas can be released in time, avoiding equipment damage or discomfort to the patient. The sealing disc 79 squeezes the compression spring 78, and the function of the compression spring 78 is to provide a resilience force. When the pressure decreases, the spring will return to its original state to ensure that the sealing disc 79 can be normally closed. The excessive air is discharged to the sealing frame 72 through the through hole 71 and then discharged through the whistle 73. At this time, the whistle 73 makes a sound to prompt the operator, and then the solenoid valve 57 can be closed to prevent the input of high-pressure air, playing a prompting role. When a greater pressure is required, the control motor 74 is started to drive the pressure sensor 75 and the connecting block 77 to further compress the compression spring 78. If a greater pressure is needed to complete the task, the control motor 74 can further adjust the compression amount of the compression spring 78, thereby playing a role in adjusting the maximum air pressure of the fist clenching mechanism 5.

[0040] In summary, when using the automatic blood sample collection device for ankylosing spondylitis:

[0041] The recognition device 45 is used for downward visual recognition of the vein position. By acquiring the vein image of the patient's hand, combining with the image processing algorithm to analyze the vein trend and the optimal puncture point, and transmitting this information to the electric universal rotating member 42 to adjust the angle and position of the puncture device 43 to ensure accurate puncture. The recognition device 45 first performs vein recognition, acquires the coordinate information of the vein position, and transmits it to the control system. The control system adjusts the angle of the electric universal rotating member 42 according to the recognition data, so that the puncture device 43 accurately aligns with the target vein. After the adjustment is completed, the puncture device 43 is activated, and the puncture head 44 slowly descends and punctures into the blood vessel to ensure an appropriate puncture depth, and then blood extraction is performed. During the whole process, the main shaft 41 provides structural support to ensure the stable operation of each component. The recognition device 45 continuously monitors the blood vessel state to avoid puncture failure caused by blood vessel movement or collapse.

[0042] The high-pressure air output device 55 is connected to the flexible glove 54 through the high-pressure connecting pipe 1 56 and the electromagnetic valve 1 57. When the electromagnetic valve 1 57 is opened, high-pressure air enters the corrugated pipe 59, causing the corrugated pipe 59 to elongate and undergo axial extension. This extension generates a certain traction force on the hollow connecting bar 58 and the positioning hollow block 510. Since the top of the flexible glove 54 is provided with triangular prism grooves, and the triangular prism grooves are arranged in an array, these groove structures form local stress concentration areas, causing the flexible glove 54 to bend in a predetermined direction when subjected to an external force. When the corrugated pipe 59 is pushed by high-pressure air to elongate, multiple triangular prism grooves on the flexible glove 54 will deform synchronously along the arrangement direction, causing the overall glove to bend inward, simulating the natural flexion movement of the fingers, so as to drive the palm of the ankylosing spondylitis patient to complete the clenching action.

[0043] When the system receives the instruction to start blood collection, the electromagnetic valve 2 61 is activated, allowing high-pressure air to be transmitted through the high-pressure connecting pipe 2 62 to the fixed hollow block 63, and pushing the air to flow into the blowing mechanism 6. The air blows towards the hand in a circumferential array direction through the oblique jet orifice 65, warming the patient's hand. At the same time, the hand temperature is increased through the heating device 66 to promote blood vessel dilation and enhance the visibility of the veins. In addition, the oblique jet orifice 65 ensures uniform air flow distribution, which helps the glove to expand and simulate the clenching action of the hand, and finally helps to complete venous filling and prepare for blood collection. During this process, the air in the corrugated pipe 59 and the positioning hollow block 510 is output, and at this time the flexible glove 54 will not be curled. Until the patient's arm is heated for a period of time, the electromagnetic valve 2 61 is closed. At this time, there is enough high-pressure air in the clenching mechanism 5 for clenching, ensuring that after the patient's hand is heated to an appropriate temperature, there is enough high-pressure air in the clenching mechanism 5 to assist in clenching. This design not only ensures the comfort of the hand, but also optimizes blood flow and venous filling, making the blood collection process smoother.

[0044] When the high-pressure air pressure in the corrugated pipe 59 and the positioning hollow block 510 is too high, the high-pressure air pushes open the sealing disc 79 through the through-hole 71 on the hollow connecting strip 58. This design ensures that when the system pressure is too high, excess gas can be released in a timely manner, avoiding equipment damage or discomfort to the patient. The sealing disc 79 squeezes the compression spring 78. The function of the compression spring 78 is to provide a resilience force. When the pressure decreases, the spring will return to its original state to ensure that the sealing disc 79 can be normally closed. The excess air is discharged through the through-hole 71 into the sealing frame 72 and then discharged through the whistle 73. At this time, the whistle 73 emits a sound to prompt the operator, and then the solenoid valve 1 57 can be closed to prevent the input of high-pressure air, playing a prompting role.
