[0002] For limb correction, wrist and arm treatment, physical therapy dressing, blood drawing and other operations for children and adults, during the treatment process, patients often shake or move their limbs unconsciously due to pain, and restraints are used to restrain them.

[0003] In the medical field, drawing blood from children is a common but challenging operation. When drawing blood from children, most existing restraints are used to tighten the children with straps. However, during the restraint process, children are prone to moving around randomly due to nervousness, fear, and other emotions, such as pulling the blood collection tube and interfering with the normal operation of medical staff. This not only affects the smooth progress of the blood drawing operation, but may also cause accidental injuries to children, resulting in poor blood drawing protection. Moreover, it is impossible to provide stable support for the arms when moving around, causing discomfort to children. In addition, the restraint cannot be adaptively adjusted according to the thickness of the child's arm, which causes medical staff to waste time in the early restraint process, reduces the restraint efficiency, and makes it difficult to effectively restrain the patient, which interferes with the normal progress of treatment, reduces the treatment effect, and makes it difficult to ensure the stability of treatment.

[0029] like Figures 1 to 10 As shown, an embodiment of the present invention provides an ergonomic blood extraction restraint for children, including a cross base 1, which is designed in the shape of a "cross" so as to provide stable support on a plane, ensuring that the restraint will not easily shake or shift during use. The cross base 1 is rotatably connected to a first arc frame 101 and a second arc frame 102, respectively. A slide bar 2 is slidably connected at the intersection of the first arc frame 101 and the second arc frame 102. An arc-shaped abutment plate 21 is fixed to the bottom surface of the slide bar 2. Through the rotation of the first arc frame 101 and the second arc frame 102, the placement table 3 can rotate freely within a certain range, so that the angle can be adjusted according to actual needs. like Figure 1 and Figure 2 As shown, a placement table 3 is fixed on the top surface of the slide bar 2 for placing the child's limbs that need to be applied with medicine, the arms that need to be drawn blood, etc. The surface of the placement table 3 is smooth and has a certain degree of softness to avoid causing compression or discomfort. A placement groove 4 is provided in the placement table 3. In order to facilitate the sliding of the slide bar 2 therein, thereby realizing the flexible movement of the slide bar 2 between the two arc-shaped frames, an induction sheet sensor 5 is installed on the inner wall of the placement table 3. It should be noted that the model of the induction sheet sensor 5 is EZ-LS. When the child's arm is placed on the test table, the induction sheet sensor 5 can respond quickly and calculate the limb position, arm circumference and other information through its internal matching measurement system, so that subsequent adaptive adjustment can be achieved, avoiding the problem of excessive restraint during the restraint process causing muscle tension and joint stiffness in the patient's elbows and palms, or excessive loose restraint resulting in poor restraint effect, thereby improving the comfort level.

[0030] A circular table frame 6 is fixed on the placement table 3, which can limit the moving direction of the first pressure claw 74 to ensure its stable vertical sliding. A rotating rod 91 is rotatably connected to the placement table 3, and a guardrail 9 is fixedly sleeved on the rotating rod 91. The overlapping part of the placement table 3 and the guardrail 9 is arranged in a semi-arc shape. The rotation of the rotating rod 91 can drive the guardrail 9 to rotate. By controlling the rotation angle of the rotating rod 91, the position of the guardrail 9 can be adjusted to achieve effective shielding, preventing children from touching and moving around when medical staff perform limb correction, wrist and arm treatment, physical therapy, dressing, and blood drawing on children, without causing excessive restraint on the children.

[0031] like Figure 1 and Figure 2 As shown, a constraint assembly 7 is installed on the placement table 3, and the constraint assembly 7 includes a first pressure claw 74 slidably connected to the circular table frame 6, the end of the first pressure claw 74 is fixedly connected to an L-shaped frame 75, the bottom of the L-shaped frame 75 is fixedly connected to a second pressure claw 77, and the end of the second pressure claw 77 is installed with a disinfection assembly 8.

[0032] like Figure 3 As shown, an annular groove is provided inside the first arc frame 101 and the second arc frame 102 to facilitate the sliding of the slide bar 2. The top surface of the arc-shaped support plate 21 slides in contact with the bottom surface of the second arc frame 102, ensuring the stability of the slide bar 2 during movement. At the same time, it also enables the placement platform 3 to better contact the child's arm, providing certain support and restraint.

[0033] like Figure 2 As shown, the bottom surface of the placement table 3 is fixedly connected to a base 71, and a motor 72 is fixedly connected to the base 71. The motor 72 is electrically connected to the inductive sheet sensor 5. The output end of the motor 72 is fixedly connected to a screw rod 73, and the screw rod 73 is rotatably installed on the placement table 3. The first pressure claw 74 is threadedly connected to the screw rod 73. A guide rod 76 is fixedly connected to the placement table 3, and the first pressure claw 74 is slidably sleeved with the guide rod 76.

[0034] Again Figure 2 As shown, a gear 93 is fixedly connected to the rotating rod 91 , and a tooth plate 92 is fixedly connected to the side wall of the first pressing claw 74 , and the gear 93 and the tooth plate 92 are meshed with each other.

[0035] like Figure 1 and 2 As shown, in actual operation, whether it is limb correction, wrist and arm treatment, physical therapy dressing, or blood drawing, the patient needs to place the arm to be treated in the placement slot 4 of the placement table 3. In the process of placing the arm, the arm will come into contact with the induction sheet sensor 5. The induction sheet sensor 5 can quickly and accurately sense the position, circumference and other detailed information of the child or adult's limb, and quickly integrate and process this information, convert it into data and generate an electrical signal, which is transmitted to the motor 72. After receiving the signal, the motor 72 starts immediately and drives the screw rod 73 to rotate. Since the first pressure claw 74 and the screw rod 73 are tightly matched through the thread, when the screw rod 73 rotates, the first pressure claw 74 will move downward under the action of the thread, so that the first pressure claw 74 can fit tightly against the rear end of the limb and firmly clamp and limit it. This design enables the equipment to fit closely to the contour of the patient's arm when performing limb correction, wrist and arm treatment, physical therapy dressing, blood drawing and other operations, greatly enhancing the stability of the constraint.

[0036] While the first pressing claw 74 moves downward, because the second pressing claw 77 is firmly connected to the first pressing claw 74 through the L-shaped frame 75, and the initial position of the second pressing claw 77 is lower than the first pressing claw 74, when the first pressing claw 74 moves downward, the second pressing claw 77 will move downward synchronously and fit against the rear end of the patient's arm. In this way, during various operations, the device can better adapt to the contour of the patient's arm and fit closely to the rear end of the arm, further improving the stability of the restraint.

[0037] After the affected limb is properly restrained, if a child or adult patient moves his or her limbs during limb correction, wrist and arm treatment, physical therapy dressing, blood drawing and other operations, the movement of the arm will be transmitted to the slide bar 2 through the placement table 3, and the slide bar 2 will slide accordingly in the sliding track at the intersection of the first arc frame 101 and the second arc frame 102. At the same time, the first arc frame 101 and the second arc frame 102 will rotate according to the direction and strength of the arm movement, so that the placement table 3 can adjust the position and angle in real time to adapt to the movement of the child's arm. Through the flexible adjustment of the placement table 3, the equipment can always keep a close fit with the child's arm during use, providing continuous and stable support for the arm, and effectively reducing the discomfort caused by the child's limb movement.

[0038] In the process of the first pressure claw 74 moving downward, the tooth plate 92 on its side wall also moves downward and contacts the gear 93. Since the tooth plate 92 and the gear 93 are meshed with each other, the gear 93 will rotate when it is subjected to the force transmitted by the tooth plate 92, thereby driving the rotating rod 91 connected to it to rotate. As the rotating rod 91 rotates, the fence 9 on the outside of the rotating rod 91 will also rotate and overlap with the arc-shaped part of the placement table 3 to form a shielding area, which effectively prevents children from pulling the blood collection tube or other auxiliary tools due to tension, fear, etc. during limb correction, wrist and arm treatment, physical therapy dressing, and blood drawing, thereby interfering with the normal operation of medical staff, improving the protection effect during limb correction, wrist and arm treatment, physical therapy dressing, blood drawing, etc., and providing strong guarantee for medical staff to complete limb correction, wrist and arm treatment, physical therapy dressing, and blood drawing operations.

[0039] It should be noted that, in this technical solution, although the device is mainly used in the scenario of drawing blood from children, in actual application, it has a wider range of applications, covering multiple different operation directions such as limb correction, wrist and arm treatment, physical therapy and dressing for children or adults. During limb correction and wrist and arm treatment, patients often feel pain due to the treatment, which can easily cause the patient to unconsciously move their limbs. The patient's unconscious movement will interfere with the normal progress of the treatment and reduce the treatment effect. The restraint can effectively restrain the patient, which can minimize the patient's limb shaking caused by pain, thereby improving the stability of the treatment and providing a strong guarantee for the smooth progress of the treatment.

[0040] like Figures 4 to 8 As shown, the disinfection assembly 8 includes a connecting post 81 fixedly connected to the surface of the second pressing claw 77, a sliding post 83 is slidably connected in the connecting post 81, a sliding track is provided for the sliding post 83, and the sliding post 83 can slide freely in the connecting post 81. This sliding connection mode allows the sliding post 83 to adjust its position according to actual needs, so that it can be displaced accordingly when adapting to different patient arm lengths or during the operation of the restrainer. The rotation of the sliding post 83 end is connected with a rotating shaft 85, and the rotating shaft 85 end is fixedly connected with a storage bin 86. A plurality of iodine cotton swabs 814 are placed in the storage bin 86. A latch 82 is inserted into the connecting post 81, and a plurality of sockets 84 are provided on the sliding post 83, and the latch 82 is plugged into the socket 84. When the position of the sliding column 83 needs to be adjusted, the pin 82 can be manually pulled out to allow the sliding column 83 to slide in the connecting column 81; after adjusting to the appropriate position, the pin 82 is inserted into the corresponding socket 84 to fix the sliding column 83 and the connecting column 81, ensuring that the position of the disinfection component 8 is relatively stable when the restraint is used.

[0041] The side wall of the storage bin 86 is provided with an arc-shaped groove 861, and a cover plate 87 is clamped on the top of the storage bin 86 to close the storage bin 86 to prevent the iodine cotton swab 814 from being contaminated by the outside world or accidentally falling off. A first arc-shaped plate 88 is fixedly connected to one side of the bottom of the storage bin 86, and a rotating rod 89 is rotatably connected to the other side of the bottom of the storage bin 86. A second arc-shaped plate 810 is fixedly sleeved on the rotating rod 89, and a protruding rod 811 is fixedly connected to the end of the rotating rod 89. The end of the protruding rod 811 is fixedly connected to a connecting rod 812. The connecting rod 812 is fixedly connected to one end of a spring 813, and the other end of the spring 813 is fixedly connected to the inner wall of the arc-shaped groove 861. In the initial state, the iodine swab 814 is stuck between the first curved plate 88 and the second curved plate 810. When the iodine swab 814 needs to be used for disinfection, the second curved plate 810 is driven to rotate by operating the rotating rod 89, thereby changing the distance between the first curved plate 88 and the second curved plate 810, so that the iodine swab 814 can fall down for disinfection.

[0042] like Figures 4 to 8 As shown, before using the restraint, it is necessary to make corresponding adjustments according to the length of the patient's arm. When adjusting, manually pull out the pin 82 to disengage the pin 82 from the socket 84 on the slide post 83 and the connecting post 81, and then pull the storage bin 86 to drive the slide post 83 to slide outward in the connecting post 81. After sliding to the appropriate position, insert the pin 82 into the connecting post 81 and make it pass through the corresponding socket 84, so as to achieve fixation between the slide post 83 and the connecting post 81.

[0043] Then, the sterilized cotton swabs are stacked in sequence and placed in the storage bin. As the sterilized cotton swabs are placed, the sterilized cotton swab at the bottom will be stuck between the first curved plate 88 and the second curved plate 810 due to the force, and the bottom of the sterilized cotton swab will slide out to a distance that just fits the skin.

[0044] When the preparations are ready, during the treatment of limb correction, wrist and arm treatment, physical therapy dressing, blood drawing and other treatment operations, the motor 72 is started, and the motor 72 drives the screw rod 73 to rotate. Since the first pressing claw 74 and the screw rod 73 are installed by threads, the screw rod 73 will drive the first pressing claw 74 to move downward under the action of the threads. Moreover, since the first pressing claw 74 and the second pressing claw 77 are fixedly connected by the L-shaped frame 75, during the process of the first pressing claw 74 and the second pressing claw 77 pressing downward, the connecting column 81 is fixedly connected to the second pressing claw 77, and the sliding column 83 is connected to the connecting column 81. The column 81 is slidably connected, and the storage bin 86 is rotationally connected to the sliding column 83 via the rotating shaft 85. Then, when the second pressing claw 77 slides down, the connecting column 81 will synchronously drive the storage bin 86 to move downward. Since the height of the storage bin 86 is higher than the second pressing claw 77, the storage bin 86 will first contact the patient's skin during the downward movement. Since multiple sterile cotton swabs are placed in the storage bin 86, as the second pressing claw 77 continues to move downward, the sterile cotton swabs at the bottom of the storage bin 86 will be deflected when they contact the skin, thereby causing the storage bin 86 to drive the rotating shaft 85 to rotate in the sliding column 83. As the storage bin 86 continues to rotate, the sterile cotton swabs at its bottom will slide along the skin surface of the affected limb, and the iodine-containing liquid in the sterile cotton swabs will contact the skin surface, thereby producing a sterilizing effect.

[0045] After the disinfection is completed, since the protruding rod 811, the rotating rod 89 and the connecting rod 812 are fixedly connected, after the disinfection is completed, the protruding rod 811 is manually pressed, and the force on the protruding rod 811 will drive the rotating rod 89 to rotate. At the same time, the connecting rod 812 at the end of the protruding rod 811 will slide along the arc groove 861 and squeeze the spring 813. As the rotating rod 89 rotates, the second arc plate 810 fixed to the rotating rod 89 will also rotate. As the second arc plate 810 rotates, the resistance distance between the first arc plate 88 and the second arc plate 810 will change, causing the used disinfection cotton swab to fall off. After the disinfection cotton swab falls, it will be pressed by the spring 813. When used, the connecting rod 812 will immediately reset and slide, and the protruding rod 811 and the rotating rod 91 fixed thereto will also rotate and reset synchronously, so that the second curved plate 810 can quickly rotate to the initial position. In the process of resetting the second curved plate 810, since multiple sterile cotton swabs are arranged in the storage bin 86, as the sterile cotton swab at the bottom falls, the remaining sterile cotton swabs will move down under the action of inertia, so that the unused sterile cotton swabs are stuck between the first curved plate 88 and the second curved plate 810, and slide out to a distance that can fit the skin. In this way, when performing subsequent operations, the sterile cotton swabs can be quickly replaced without the need for staff to take them extra, which saves time and effort.

[0046] The auxiliary assembly 11 includes an electric push rod 111 fixed to the second pressure claw 77. The output end of the electric push rod 111 is fixedly connected to a connecting plate 112. A fixing rod 113 is fixed to the surface of the connecting plate 112. The function of the fixing rod 113 is to install the medical tape 12 and provide a mounting position for the blocking plate 115. The fixing rod 113 is provided with an external thread 114, which is threadedly connected to the blocking plate 115 to limit the position of the medical tape 12 and prevent it from shifting or slipping during use. A blade 116 is fixed on the connecting plate 112, and two limiting rollers 117 are fixed on the connecting plate 112. The limiting rollers 117 guide and limit the medical tape 12 to keep the medical tape 12 flat and stable during use, and prevent the medical tape 12 from wrinkling or twisting. The fixing rod 113 is sleeved with the medical tape 12. The medical tape 12 is sticky and can be used to fix and restrain the patient's body parts. When medical staff perform limb correction, wrist and arm treatment, physical therapy dressing, blood drawing and other operations, they need to put the bandages for the required fixed medicines in advance to prevent the medical tape 12 from wrinkling or twisting. The blood-stained cotton swab is pulled and pasted on the back of the hand in advance. Then, after limb correction, wrist and arm treatment, physical therapy dressing, and blood drawing, the required bandage or medical tape 12 is pasted on the wound for auxiliary reinforcement. An auxiliary component 11 is added to the device. During auxiliary fixation, the medical tape 12 is pulled so that it can cover the part that needs to be fixed, thereby completing the reinforcement of the wound and saving the medical staff the steps of preparing in advance and pressing to fix. The side wall of the second pressing claw 77 is fixedly connected to the connecting frame 10, and the connecting frame 10 is equipped with an infrared scanner 13.

[0047] The fixing rod 113 is sleeved with a medical tape 12 , and the electric push rod 111 is electrically connected to the infrared scanner 13 , and the electric push rod 111 is electrically connected to the infrared scanner 13 , and can receive signals from the infrared scanner 13 and make corresponding action instructions.

[0048] It should be noted that the model of the infrared scanner 13 is XTP, which can scan and locate the blood drawing site and transmit the location information to the subsequent control system to facilitate further accurate positioning of the location where the medical tape 12 is required to be used.

[0049] like Figure 1 and Figure 9 As shown, before carrying out limb correction, wrist and arm treatment, physical therapy dressing or blood drawing operations, it is necessary to first rotate the sealing plate 115 off the fixed rod 113 to separate it from the fixed rod 113, thereby releasing the limit on the fixed rod 113, and then put the medical tape 12 on the fixed rod 113, gently pull out one end of the tape, and clamp it between the two limiting rollers 117, and then reinstall the sealing plate 115 back to its original position, so that the medical tape 12 is firmly clamped, ready for subsequent operations.

[0050] During limb correction, wrist and arm treatment, physical therapy dressing or blood drawing, the infrared scanner 13 scans and locates the specific location of blood drawing, and then converts the acquired location information into a signal and transmits it to the electric push rod 111. After receiving the signal, the electric push rod 111 pushes the medical tape 12 toward the area where the medical tape 12 needs to be pulled to stop bleeding. When the medical tape 12 is pushed to the target area, the electric push rod 111 stops driving.

[0051] Then the medical staff starts to pull the medical tape 12. During the pulling process, the medical tape 12 will start to rotate under the action of force, and the medical tape 12 will be attached to the patient's affected limb. When the sticking operation is completed, the medical staff gently pulls the medical tape 12 to make it contact with the blade 116. Under the action of the blade 116, the medical tape 12 can be quickly cut off. In this way, after the limb correction, wrist and arm treatment, physical therapy dressing or blood drawing operation is completed, the bandage or medical tape 12 can be quickly attached to the affected area to play an auxiliary reinforcement role on the affected area, ensuring that the affected area can receive timely and effective care.
