[0030] Embodiment:

[0031] Please refer to Figures 1 - 2 , the present invention provides a technical solution: a blood extraction device for pediatric internal medicine, including an upper limb posterior arm supporting seat 1 and an upper limb anterior arm supporting seat 2. The upper limb posterior arm supporting seat 1 is used to support the posterior arm part of the child's upper limb, and the upper limb anterior arm supporting seat 2 is connected to the upper limb posterior arm supporting seat 1 to support the anterior arm part. The outer walls of the tops of the upper limb posterior arm supporting seat 1 and the upper limb anterior arm supporting seat 2 are both provided with arm placement grooves 3, and the outer wall of the top of the upper limb anterior arm supporting seat 2 is provided with a line of sight blocking device 4 and an anterior arm limiting structure 5;

[0032] The line of sight blocking device 4 includes a liftable lifting baffle 405 and a video player 407 arranged above the lifting baffle 405, and further includes an attention diversion structure 409;

[0033] The anterior arm limiting structure 5 is arranged at the rear side of the line of sight blocking device 4, and the anterior arm limiting structure 5 is used to limit the position of the anterior arm.

[0034] In this embodiment, when drawing blood, place the child's arm in the groove of the supporting seat, lower the lifting baffle 405 to block the line of sight, and the video player 407 and the attention diversion structure 409 divert the attention; the anterior arm limiting structure 5 limits the anterior arm to ensure the smooth progress of blood collection.

[0035] Please refer to Figures 3 - 6, the line-of-sight blocking device 4 includes a fixing frame 401, which is vertically installed on the top of the upper limb forearm support seat 2. A baffle moving groove 402 is formed on the outer wall of the top of the fixing frame 401. Through grooves 403 are formed on both sides of the outer wall of the fixing frame 401 and are in communication with the baffle moving groove 402. Tooth moving grooves 404 are formed on both outer walls of the fixing frame 401, and the tooth moving grooves 404 are in communication with the through grooves 403.

[0036] A lifting baffle 405 is movably connected to the inner wall of the fixing frame 401. Tooth plates 4051 are fixedly connected to both outer walls of the lifting baffle 405, and the outer walls of the tooth plates 4051 are slidably connected to the inner walls of the through grooves 403.

[0037] A connecting frame 406 is fixedly connected to the outer wall of the top of the fixing frame 401, and a video player 407 is installed on the outer wall of the top of the connecting frame 406.

[0038] A driving structure 408 is fixedly connected to one outer wall of the fixing frame 401. The driving structure 408 includes a first protective cover 4081. A driving gear 4082 is rotatably connected to the inner wall of the first protective cover 4081. The outer wall of the tooth plate 4051 is meshed with the outer wall of the driving gear 4082.

[0039] In this implementation scheme, when the first motor 4083 is started, its output shaft drives the driving gear 4082 to rotate. When the driving gear 4082 rotates, it drives the tooth plate 4051 to slide in the through groove 403. While the tooth plate 4051 slides, since the tooth plates 4051 are fixedly connected to both outer walls of the lifting baffle 405, the lifting baffle 405 will move up and down on the inner wall of the fixing frame 401, thus realizing the lifting function of the lifting baffle 405. When the lifting baffle 405 descends, it can block the child's line of sight and reduce the child's attention to the blood drawing process.

[0040] The video player 407 installed on the top of the connecting frame 406 can play videos. By playing interesting videos, it can further distract the child's attention and reduce the child's fear of the blood drawing process.

[0041] Please refer to Figures 1 - 2 and Figure 3 、 Figure 5, attention diversion structures 409 are provided on both outer walls of the fixing frame 401. The attention diversion structures 409 include second protective covers 4091. Second protective covers 4091 are fixedly connected to both outer walls of the fixing frame 401. The second protective covers 4091 are vertically and arrayedly distributed on the outer wall of the fixing frame 401. A driven gear 4092 is rotatably connected to the inner wall of the second protective cover 4091. The outer wall of the driven gear 4092 meshes with the outer wall of the toothed plate 4051. A windmill 4093 is rotatably connected to the front outer wall of the second protective cover 4091. A rotating shaft is fixedly connected to one outer wall of the windmill 4093. One end of the rotating shaft is fixedly connected to the outer wall of the driven gear 4092.

[0042] In this implementation, the driven gear 4092 in the second protective cover 4091 on both sides of the fixing frame 401 meshes with the toothed plate 4051. When the toothed plate 4051 slides, it will drive the driven gear 4092 to rotate. The driven gear 4092 is connected to the windmill 4093 through a rotating shaft. When the driven gear 4092 rotates, it will drive the windmill 4093 to rotate. The rotating windmill 4093 can attract the attention of children, play a role in diverting the attention of children, and relieve the tension of children.

[0043] Please refer to Figures 7 - 8 , the forearm limiting structure 5 includes a fixing plate 501. Fixing plates 501 are fixedly connected to both outer walls of the upper limb forearm supporting seat 2. A lifting groove 502 is formed on one outer wall of the fixing plate 501. A lead screw 503 is rotatably connected to the inner wall of the lifting groove 502. A second motor 504 is fixedly connected to the top outer wall of the fixing plate 501. The output shaft of the second motor 504 is connected to one end of the lead screw 503. A lifting block 505 is slidably connected to the inner wall of the lifting groove 502. A blocking rod 506 is fixedly connected to the outer wall of the lifting block 505. An airbag 507 is fixedly connected to the outer wall of the blocking rod 506.

[0044] A protrusion 5071 is integrally formed at the bottom of the airbag 507. An air pipe 5072 is fixedly connected to the inner wall of the airbag 507. The other end of the air pipe 5072 is connected to an air pump.

[0045] In this implementation, start the second motor 504. Its output shaft drives the lead screw 503 to rotate in the lifting groove 502. Since the lifting block 505 is threadedly connected to the lead screw 503 and the lifting block 505 slides in the lifting groove 502, when the lead screw 503 rotates, it will drive the lifting block 505 to slide up and down in the lifting groove 502. When the lifting block 505 slides, the blocking rod 506 fixedly connected to the lifting block 505 will also move up and down accordingly; when it is necessary to limit the arm, the blocking rod 506 moves downward, and the blocking rod 506 limits the arm to prevent the child from moving the arm;

[0046] The airbag 507 fixedly connected to the shift lever 506 can limit the forearm of the child, preventing the child's arm from moving randomly during blood drawing. The material of the airbag 507 is soft, which can avoid discomfort to the child. The air pump inflates the airbag 507 through the air pipe 5072. When the airbag 507 expands, the protrusion 5071 integrally formed at its bottom can increase the friction with the child's forearm, further improving the limiting effect on the child's forearm and ensuring that the child's arm remains stable during blood drawing.

[0047] During blood drawing, place the arm on the upper arm rear arm support 1 and the upper arm forearm support 2. The medical staff binds the arm and starts the first motor 4083. The output shaft of the motor drives the driving gear 4082 to rotate. When the driving gear 4082 rotates, it drives the rack 4051 to slide in the chute 403. While the rack 4051 slides, since the two outer walls of the lifting baffle 405 are fixedly connected to the rack 4051, the lifting baffle 405 will move up and down on the inner wall of the fixed frame 401, thus realizing the lifting function of the lifting baffle 405. When the lifting baffle 405 descends, it can block the child's sight and reduce the child's attention to the blood drawing process.

[0048] The driven gear 4092 in the protective covers 4091 on both sides of the fixed frame 401 meshes with the rack 4051. When the rack 4051 slides, it drives the driven gear 4092 to rotate. The driven gear 4092 is connected to the windmill 4093 through a rotating shaft. When the driven gear 4092 rotates, it drives the windmill 4093 to rotate. The rotating windmill 4093 can attract the child's attention, play a role in diverting the child's attention, and relieve the child's nervousness.

[0049] The video player 407 installed at the top of the connecting frame 406 can play videos. By playing interesting videos, it can further divert the child's attention and reduce the child's fear of the blood drawing process.

[0050] Start the second motor 504. The output shaft of the motor drives the lead screw 503 to rotate in the lifting groove 502. Since the lifting block 505 is threadedly connected to the lead screw 503 and the lifting block 505 slides in the lifting groove 502, when the lead screw 503 rotates, it drives the lifting block 505 to slide up and down in the lifting groove 502. When the lifting block 505 slides, the shift lever 506 fixedly connected to the lifting block 505 will also move up and down accordingly; when it is necessary to limit the arm, the shift lever 506 moves downward, and the shift lever 506 limits the arm to prevent the child from moving the arm.

[0051] The airbag 507 fixedly connected to the shift lever 506 can limit the forearm of a child, preventing the child's arm from moving randomly during blood drawing. The material of the airbag 507 is soft, which can avoid discomfort to the child. The air pump inflates the airbag 507 through the air tube 5072. When the airbag 507 expands, the convex part 5071 integrally formed at its bottom can increase the friction with the child's forearm, further improving the limiting effect on the child's forearm and ensuring that the child's arm remains stable during blood drawing.

[0052] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
