Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figure 1 As shown;

[0027] A venipuncture fixation device includes a mounting plate 1, a shield 11 fixedly connected to the upper surface of the mounting plate 1, and a display screen 12 mounted on the surface of the shield 11. The display screen 12 is mounted on the surface of the shield 11, and a controller 13 is mounted on the surface of the display screen 12. A placement groove 14 is opened on the surface of the mounting plate 1, and a fixing ring 15 is fixedly connected in a through groove opened on the surface of the shield 11.

[0028] In this implementation plan: When children undergo intravenous puncture for blood collection, they are often uncooperative with medical staff, which is not conducive to the success of the operation. Therefore, a fixation component 2, an airbag component 3, and a limiting component 4 are added to address this issue.

[0029] It should be noted that: the shield 11 can block the child's view and prevent the child from being afraid of observing the actions of medical staff; the display screen 12 and controller 13 can divert the child's attention and facilitate the operation of medical staff; the placement slot 14 is convenient for medical staff to keep medical instruments away; the fixing ring 15 is convenient for the child to reach out to the medical staff; the gesture sensor switch 215 is electrically connected to the fan 31, solenoid valve 37 and solenoid valve 38 respectively through wires; the gesture sensor switch 215 controls the fan 31, solenoid valve 37 and solenoid valve 38 differently by rotating the handle 26; the control plate 48 is electrically connected to the sensor 44 and the fan 47 respectively through wires; when the handle 26 contacts the sensor 44, the control plate 48 starts the fan 47.

[0030] Furthermore:

[0031] like Figures 1 to 7 As shown:

[0032] Based on the above:

[0033] It also includes a fixing component 2 disposed on the surface of the mounting plate 1, an airbag component 3 disposed on the surface of the fixing component 2, and a limiting component 4 disposed on the surface of the fixing component 2.

[0034] The fixing component 2 includes a fixing shell 21 fixedly connected to the upper surface of the mounting plate 1. A toothed ring 22 is provided inside the fixing shell 21. A lead screw 28 is rotatably connected to a rectangular cavity opened inside the mounting plate 1 through two bearing seats. A gear 27 is fixedly connected to one end of the lead screw 28. The gear 27 and the toothed ring 22 are meshed and connected through a through groove 2 opened on the surface of the mounting plate 1. A moving block 29 is threadedly connected to the surface of the lead screw 28. A telescopic rod 210 is symmetrically fixedly connected to the surface of the moving block 29. A connecting rod 211 is fixedly connected to the telescopic end of the telescopic rod 210. Two arc-shaped grooves 212 are opened on the upper surface of the mounting plate 1. The two connecting rods 211 are slidably connected to the mounting plate 1 through the two arc-shaped grooves 212 respectively. An arc-shaped block 213 is fixedly connected to the top end of the connecting rod 211.

[0035] The surface of the toothed ring 22 is symmetrically provided with annular grooves 23. Rollers 25 are symmetrically arranged inside the annular grooves 23. A fixed rod 24 is rotatably connected to a circular groove on the surface of the roller 25. The fixed rod 24 is fixedly connected to the fixed shell 21. The roller 25 is rotatably connected to the toothed ring 22 through the annular grooves 23. A handle 26 is provided inside the toothed ring 22. A handle 214 is fixedly connected to the surface of the handle 26. A gesture sensing switch 215 is installed on the surface of the fixed shell 21.

[0036] In this implementation plan: Before performing intravenous puncture on a child, the child's arm is passed through the fixing ring 15 and the child's palm grasps the handle 26. Medical personnel can, depending on the puncture site, such as the back of the hand or the median venous vein at the elbow, rotate the toothed ring 22 180 degrees clockwise or counterclockwise via the handle 214 on the handle 26. This causes the gear 27 to drive the lead screw 28 to rotate. The rotation of the lead screw 28 causes the moving block 29 to move on the surface of the lead screw 28. The movement of the moving block 29 causes the connecting rod 211 on the surface of the telescopic rod 210 to move along the inner wall of the arc-shaped groove 212, thereby causing the arc-shaped block 213 to move towards the arm. The grip 26 moves in a certain direction. When the grip 26 rotates 180 degrees counterclockwise, the two arc-shaped blocks 213 are closer to the median cubital vein. When the grip 26 rotates 180 degrees clockwise, the two arc-shaped blocks 213 are closer to the dorsal vein of the hand. This makes the child's arm struggle less when medical personnel perform venipuncture. The toothed ring 22 is restricted inside the fixed housing 21 by the fixed rod 24 fixed inside the fixed housing 21. The toothed ring 22 can rotate inside the fixed housing 21 by the action of the roller 25 and the annular groove 23, so that the toothed ring 22 can drive the gear 27 to rotate. The gesture sensor switch 215 can sense the rotation direction of the grip 26.

[0037] It should be noted that the surface of the movable block 29 is in contact with the inner wall of the mounting plate 1, which facilitates the movement of the movable block 29 on the surface of the lead screw 28. The size of the arc groove 212 allows the handle 26 to rotate at a maximum angle of 180 degrees in a clockwise or counterclockwise direction. The resistance of the movable block 29 moving within the mounting plate 1 makes it difficult for children to turn the handle 26.

[0038] Furthermore:

[0039] In an optional embodiment, the airbag assembly 3 includes a fan 31 mounted on the upper surface of the mounting plate 1. A ventilation hose 32 is fixedly connected to the air outlet of the fan 31. An airbag 33 is fixedly connected to the end of the ventilation hose 32 away from the fan 31. A second ventilation hose 34 is fixedly connected to a through hole 1 on the surface of the ventilation hose 32. An airbag 35 is fixedly connected to the end of the second ventilation hose 34 away from the first ventilation hose 32. The first airbag 33 is fixedly connected to a fixing ring 15. An airbag 36 is fixedly connected to a through hole 2 symmetrically opened on the surface of the second airbag 35. The two airbags 36 are fixedly connected to two arc-shaped blocks 213 respectively. A solenoid valve 37 is installed on the surface of the first ventilation hose 32, and a solenoid valve 38 is installed on the surface of the second ventilation hose 34.

[0040] In this implementation scheme: When one end of the handle 26 is rotated 180 degrees, it is sensed by the sensing area of ​​the gesture sensor switch 215, causing the blower 31 to start. When the handle 26 is rotated 180 degrees clockwise, the gesture sensor switch 215 controls the blower 31 to start and activates the solenoid valve 38, so that the airflow blown by the blower 31 is directed from the ventilation hose 32 to the ventilation hose 34, thereby inflating the airbag 36 in the two arc-shaped blocks 213, thereby compressing the vein at the wrist, facilitating venipuncture by medical personnel, and simultaneously fixing the child's arm. When the handle 26 is rotated 180 degrees counterclockwise, the blower 31 is started and the solenoid valve 37 is activated, so that the airflow blown by the blower 31 is directed from the ventilation hose 32 into the airbag 33, thereby compressing the vein above the median cubital vein in the child, thus facilitating venipuncture of the median cubital vein.

[0041] Furthermore:

[0042] In an optional embodiment, the limiting component 4 includes a circular rod 41 symmetrically arranged on the surface of the grip 26. The circular rod 41 is slidably connected to a through hole 3 opened on the surface of the grip 26. A fixing block 42 is fixedly connected to both ends of the circular rod 41. The fixing block 42 is fixedly connected to the toothed ring 22. A spring 43 is symmetrically arranged on the surface of the circular rod 41. One end of the spring 43 is fixedly connected to the fixing block 42. A sensor 44 is fixedly connected to the surface of the circular rod 41. The sensor 44 is fixedly connected to the fixing block 42. An arc-shaped piston 45 is slidably connected in a groove 1 opened inside the arc-shaped block 213. A second spring 46 is symmetrically arranged inside the arc-shaped block 213. The two ends of the second spring 46 are fixedly connected to the arc-shaped piston 45 and the arc-shaped block 213, respectively.

[0043] A fan 47 is installed inside the through hole 4 on the surface of the arc-shaped block 213, and a control plate 48 is installed on the upper surface of the mounting plate 1.

[0044] In this implementation plan: when a child does not cooperate with the medical staff's operation and struggles and shakes the handle 26, the handle 26 overcomes the elastic potential energy of the spring 43 to reciprocate on the surface of the rod 41 and continuously hits the sensor 44 on the fixed block 42, thereby activating the fan 47, which continuously increases the air pressure in the arc block 213, and causes the arc piston 45 to overcome the elastic potential energy of the spring 46 and move away from the arc block 213 until the two arc pistons 45 come into contact. At this time, the cooperation of the two arc pistons 45 and the two arc blocks 213 further restricts the child's arm and reduces the range of the child's struggle.

[0045] Working principle: Before performing intravenous puncture on a child, the child's arm is passed through the fixing ring 15 and the child's palm grasps the handle 26. Medical personnel can determine the puncture site, such as the median vein on the back of the hand or elbow, and rotate the toothed ring 22 180 degrees clockwise or counterclockwise via the handle 214 on the handle 26. This causes the gear 27 to drive the lead screw 28 to rotate. The rotation of the lead screw 28 causes the moving block 29 to move on its surface. The movement of the moving block 29 causes the connecting rod 211 on the surface of the telescopic rod 210 to move along the inner wall of the arc-shaped groove 212, thereby moving the arc-shaped block 213 towards the arm. When the handle 26 is rotated 180 degrees counterclockwise... When the handle 26 is rotated 180 degrees clockwise, the two arc-shaped blocks 213 are close to the median cubital vein. When the handle 26 is rotated 180 degrees clockwise, the two arc-shaped blocks 213 are close to the vein on the back of the hand, thus reducing the range of the child's arm struggle when medical personnel perform venipuncture on the child. The toothed ring 22 is restricted inside the fixed housing 21 by the fixed rod 24 fixed inside the fixed housing 21. The action of the roller 25 and the annular groove 23 allows the toothed ring 22 to rotate inside the fixed housing 21, thus facilitating the rotation of the gear 27 driven by the toothed ring 22. The gesture sensor switch 215 can sense the rotation direction of the handle 26. When one end of the handle 26 is rotated 180 degrees, it is sensed by the sensing area of ​​the gesture sensor switch 215, causing the wind... When the fan 31 is activated, and the handle 26 is rotated 180 degrees clockwise, the gesture sensor switch 215 controls the fan 31 to start and activates the solenoid valve 38. This allows the airflow from the fan 31 to flow through the ventilation hose 32 to the ventilation hose 34, inflating the airbags 36 within the two arc-shaped blocks 213. This inflates the airbags, compressing the veins at the wrist to facilitate venipuncture by medical personnel and simultaneously immobilizing the child's arm. When the handle 26 is rotated 180 degrees counterclockwise, the fan 31 is activated, and the solenoid valve 37 is activated. This allows the airflow from the fan 31 to flow through the ventilation hose 32 into the airbag 33, compressing the vein above the median cubital vein in the child. This facilitates puncture of the median cubital vein. When the child does not cooperate with the medical staff and struggles and shakes the handle 26, the handle 26 overcomes the elastic potential energy of the spring 43 to reciprocate on the surface of the round rod 41 and continuously hits the sensor 44 on the fixed block 42, thereby starting the fan 47. This causes the air pressure in the arc block 213 to increase continuously, which in turn causes the arc piston 45 to overcome the elastic potential energy of the spring 46 and move away from the arc block 213 until the two arc pistons 45 come into contact. At this time, the cooperation of the two arc pistons 45 and the two arc blocks 213 further restricts the child's arm and reduces the range of the child's struggle.
