[0016] The present invention provides a blood extraction device for medical examination with anti-vibration, and has the following beneficial effects:

[0017] This anti-shake blood extraction device for medical examinations has a needle assembly that can be fixed to the wrist to prevent shaking caused by external traction. At the same time, it can also limit the position of the wrist to prevent arm shaking during blood extraction from affecting subsequent blood extraction. In addition, the blood extraction assembly can perform electric or manual blood extraction operations, which is convenient to use.

[0018] 1. This anti-shake blood extraction device for medical examinations is provided with an adjustment assembly and an anti-shake limit assembly. The mutual cooperation between the slider and the chute facilitates the sliding adjustment of the position of the moving frame, and then the position of the anti-shake limit assembly can be adjusted. It is suitable for different wrist blood extraction positions. The rotation of the rotating block facilitates the rotation of the bidirectional lead screw, and then it can drive the opposite displacement of the two threaded sleeves outside the bidirectional lead screw to adjust the position movement of the two anti-shake limit assemblies, so that the two arc-shaped side frames can be adjusted. The flexible cushion layer and the airbag layer inside the arc-shaped side frame are convenient for limiting the wrist during blood extraction, and the airbag layer and the airbag ridges evenly distributed inside it can be inflated and expanded to fit the wrist, so as to further limit the position and prevent arm shaking during blood extraction from affecting subsequent blood extraction.

[0019] 2. This anti-shake blood extraction device for medical examinations is provided with a needle assembly. The puncture needle can puncture the skin, and the adhesive tape can be attached to the blood extraction puncture site to initially fix the puncture needle. The two ends of the annular airbag strip are locks and can be set on the outside of the wrist to re-fix the needle assembly, thus avoiding the situation that the fixed tube and the hose of the needle assembly shake due to external traction. At the same time, the provided hose is a flexible structure, and its slight shaking will not affect the syringe at the back. The bidirectional sealing joint facilitates the assembly of the needle assembly, the control valve and the syringe, which is convenient for use and disassembly and replacement of components.

[0020] 3. This anti-shake blood extraction device for medical examinations is provided with a blood extraction assembly. The rotation of the micro-motor facilitates the rotation of the threaded lead screw, and then it is convenient to drive the horizontal movement of the threaded sleeve, so that the connecting plate under the threaded sleeve can drive the movement of the pulling head, the piston rod and the rubber stopper, and then realize stable-rate electric blood extraction without manual operation. Since the connecting plate and the pulling head are bolt-connected, it is convenient to remove the bolt to release their connection relationship, and the position of the connecting plate can be rotated sideways through the movable rotating shaft to avoid it blocking the pulling head, so that the pulling head can be used manually for blood extraction operations. At this time, the anti-slip layer on the outside of the syringe can play an anti-slip role, and the functionality is better.

[0021] 4. The blood extraction device for medical examination with anti-shake is provided with a collection component. When using the collection tube, the control valve needs to be closed, and then pushing the rubber stopper forward can make the blood inside the syringe flow into the collection tube through the connecting tube and the one-way valve, which is convenient for collecting blood. At the same time, the setting of the one-way valve prevents the blood in the collection tube from flowing back into the syringe. The setting of the sealing joint facilitates the disassembly and replacement of the collection tube. Therefore, blood collection can be achieved without removing the syringe.

[0022] 5. The blood extraction device for medical examination with anti-shake is provided with a clamping frame and a positioning component. The telescopic rod is convenient for lifting and adjusting the positions of the clamping frame and the syringe, and the damping rotating shaft is convenient for rotating and adjusting the inclination angles of the clamping frame and the syringe.

Detailed implementation mode

[0030] The following further describes in detail the implementation mode of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0031] Please refer to Figures 1 to 2 , the present invention provides a technical solution: a blood extraction device for medical examination with anti-vibration, including a mounting plate 1, an anti-vibration limiting component 4 and a blood extraction component 11. A bearing plate 2 is fixed on one side in front of the mounting plate 1, and an adjusting component 3 is installed above the inner part of the mounting plate 1. The anti-vibration limiting component 4 is installed above the adjusting component 3, and the anti-vibration limiting component 4 includes an arc-shaped side frame 401, a flexible cushion layer 402, an airbag layer 403 and an airbag rib 404. The flexible cushion layer 402 is glued to the inner side of the arc-shaped side frame 401, and the airbag layer 403 is fixed to the inner side of the flexible cushion layer 402, and airbag ribs 404 are arranged on the inner side of the airbag layer 403. The flexible cushion layer 402 and the airbag layer 403 are both arc-shaped structures, and the airbag layer 403 and the airbag ribs 404 are integrally connected, and the airbag ribs 404 are equidistantly distributed;

[0032] The specific operation is as follows. The flexible cushion layer 402 and the airbag layer 403 on the inner side of the arc-shaped side frame 401 are convenient for limiting the wrist during blood extraction, and the airbag layer 403 and the airbag ribs 404 equidistantly distributed on the inner side thereof can be inflated and expanded to fit the wrist, so as to further limit the position and prevent the arm from shaking during blood extraction and affecting the subsequent blood extraction.

[0033] Please refer to Figures 1 to 2, the adjustment assembly 3 includes a moving frame 301, a bidirectional lead screw 302, rotating blocks 303, threaded barrels 304 and a connecting plate 305. The bidirectional lead screw 302 is rotatably installed inside the moving frame 301, and the rotating blocks 303 are connected to the outer ends of both ends of the bidirectional lead screw 302. The threaded barrels 304 are sleeved on the outer side of the bidirectional lead screw 302, and the connecting plate 305 is fixed above the threaded barrels 304, and two groups of threaded barrels 304 are provided; the adjustment assembly 3 further includes sliders 306 and chutes 307. Both sides of the moving frame 301 are in a strip-shaped opening structure, and the chute 307 is opened in the middle inside the moving frame 301. The slider 306 is fixed on one side of the moving frame 301 close to the chute 307, and the slider 306 is slidably connected to the chute 307;

[0034] The specific operation is as follows. The mutual cooperation between the slider 306 and the chute 307 facilitates the sliding adjustment of the position of the moving frame 301, and then the position of the anti-shake limit assembly 4 is adjusted by moving, which is applicable to different wrist blood-drawing positions. The rotation of the rotating block 303 facilitates the rotation of the bidirectional lead screw 302, and then the opposite displacement of the two threaded barrels 304 on the outer side of the bidirectional lead screw 302 can be driven to adjust the position movement of the two anti-shake limit assemblies 4, so that the two arc-shaped side frames 401 can move and adjust to initially clamp and limit wrists of different thicknesses.

[0035] Please refer to Figure 3 and Figure 4 , a telescopic rod 5 is installed above the bearing plate 2, and a clamping frame 7 is installed above the telescopic rod 5 through a damping rotating shaft 6. A syringe barrel 9 is arranged inside the clamping frame 7, and an anti-slip layer 10 is pasted on the outer side of the syringe barrel 9. Positioning assemblies 8 are fixed on both sides of the inner wall of the clamping frame 7, and the positioning assemblies 8 include positioning blocks 801 and rubber layers 802. The rubber layer 802 is adhesively bonded to the inner side of the positioning block 801, and the inner side surface of the rubber layer 802 is attached to the outer side surface of the syringe barrel 9;

[0036] The specific operation is as follows. The telescopic rod 5 facilitates the lifting adjustment of the positions of the clamping frame 7 and the syringe barrel 9, and the damping rotating shaft 6 facilitates the rotation adjustment of the inclination angles of the clamping frame 7 and the syringe barrel 9. The changes are relatively flexible and convenient for medical staff to use. The positioning block 801 and the rubber layer 802 inside the clamping frame 7 facilitate the positioning and fixing of the syringe barrel 9 therein.

[0037] Please refer to Figure 3 and Figure 5, the blood extraction assembly 11 is installed on the inner side of the syringe 9, and the blood extraction assembly 11 includes a rubber stopper 1101, a piston rod 1102, a pulling head 1103, a fixing frame 1104, a micro motor 1105, a threaded lead screw 1106, a threaded sleeve 1107, a movable rotating shaft 1108 and an adapter plate 1109. The rubber stopper 1101 is slidably connected to the inner wall of the syringe 9, and a piston rod 1102 is fixed to one side of the rubber stopper 1101. A pulling head 1103 is installed on the outer side of the piston rod 1102. A fixing frame 1104 is fixed above the clamping frame 7, and a micro motor 1105 is installed on one side inside the fixing frame 1104. One end of the output shaft of the micro motor 1105 is connected to a threaded lead screw 1106, and a threaded sleeve 1107 is sleeved on the outer side of the threaded lead screw 1106. The lower side of the threaded sleeve 1107 is rotatably connected to an adapter plate 1109 through a movable rotating shaft 1108; The adapter plate 1109 is bolted to the pulling head 1103, and the pulling head 1103, the piston rod 1102 and the rubber stopper 1101 are of an integrated structure;

[0038] The specific operation is as follows. The rotation of the threaded lead screw 1106 is facilitated by the micro motor 1105, and then the lateral movement of the threaded sleeve 1107 is facilitated, so that the adapter plate 1109 on the lower side of the threaded sleeve 1107 can drive the movement of the pulling head 1103, the piston rod 1102 and the rubber stopper 1101, thereby realizing stable-rate electric blood extraction without manual operation. Since the adapter plate 1109 is bolted to the pulling head 1103, it is convenient to remove the bolt to release the connection between the two, and the position of the adapter plate 1109 can be rotated sideways through the movable rotating shaft 1108 to avoid blocking the pulling head 1103, so that the pulling head 1103 can be manually used for blood extraction operation. At this time, the anti-slip layer 10 on the outer side of the syringe 9 can play an anti-slip role, and the functionality is better.

[0039] Please refer to Figure 3 , a collection assembly 12 is installed below one side of the syringe 9, and the collection assembly 12 includes a connecting pipe 1201, a one-way valve 1202, a sealing joint 1203 and a collection pipe 1204. The syringe 9 is fixedly connected to the connecting pipe 1201, and a one-way valve 1202 is installed in the middle of the connecting pipe 1201. A sealing joint 1203 is arranged below the one-way valve 1202, and a collection pipe 1204 is installed below the sealing joint 1203; The syringe 9 is internally connected to the collection pipe 1204 through the connecting pipe 1201, and the sealing joint 1203 is threadedly connected to the collection pipe 1204;

[0040] The specific operation is as follows. After closing the control valve 13, pushing the rubber plug 1101 forward can enable the blood inside the syringe 9 to be injected into the inside of the collection tube 1204 through the connecting tube 1201 and the one-way valve 1202, thereby facilitating blood collection. At the same time, the setting of the one-way valve 1202 prevents the blood inside the collection tube 1204 from flowing back into the syringe 9. The setting of the sealing joint 1203 facilitates the disassembly and replacement of the collection tube 1204. Therefore, blood collection can be achieved without removing the syringe 9.

[0041] Please refer to Figure 1 and Figure 6 As shown in the figure, a control valve 13 is installed on one side in front of the syringe 9, and both ends of the control valve 13 are connected with a double-sealed joint 14. The rear side of the control valve 13 is connected to the syringe 9 through the double-sealed joint 14, and the front side of the control valve 13 is connected with a needle assembly 15 through the double-sealed joint 14; the needle assembly 15 includes a fixed tube 1501, a flexible tube 1502, a puncture needle 1503, an adhesive patch 1504, and an annular airbag strip 1505. The front of the fixed tube 1501 is connected with a flexible tube 1502, and a puncture needle 1503 is fixed in front of the flexible tube 1502. Adhesive patches 1504 are fixed on both sides in front of the flexible tube 1502, and annular airbag strips 1505 are connected to both sides of the fixed tube 1501.

[0042] The specific operation is as follows. The puncture needle 1503 can puncture the skin. The adhesive patch 1504 can be attached to the blood-drawing puncture site to initially fix the puncture needle 1503. The two ends of the annular airbag strip 1505 are locks that can be set on the outside of the wrist to re-fix the needle assembly 15, thereby avoiding the situation where the fixed tube 1501 and the flexible tube 1502 of the needle assembly 15 are affected by external traction and shake. At the same time, the set flexible tube 1502 is a flexible structure, and its slight shake will not affect the syringe 9 at the rear. Through the double-sealed joint 14, it is convenient to assemble the needle assembly 15, the control valve 13, and the syringe 9, facilitating the use and disassembly and replacement of components.

[0043] In summary, for this blood extraction device for medical examination with anti-shake function, during use, first, the position of the moving frame 301 can be adjusted by the mutual cooperation and sliding between the slider 306 and the chute 307, and then the position of the anti-shake limit component 4 can be adjusted. Then, the wrist to be drawn blood can be placed between the anti-shake limit components 4 of the mounting plate 1. Then, by rotating the rotating block 303, the rotation of the bidirectional lead screw 302 can be driven, and then the opposite displacement of the two threaded barrels 304 on the outside of the bidirectional lead screw 302 can be driven, so that the two arc-shaped side frames 401 can be moved and adjusted. At this time, the flexible cushion layer 402 and the airbag layer 403 inside the arc-shaped side frame 401 can limit the wrist during blood drawing, and the airbag layer 403 and the airbag protrusions 404 equally distributed inside it can be inflated and expanded to fit the wrist, thereby further limiting and preventing the arm from shaking during blood drawing and affecting the subsequent blood extraction.

[0044] Then the puncture needle 1503 can be used to puncture the skin and the adhesive patch 1504 can be attached to the blood drawing puncture site to preliminarily fix the puncture needle 1503, and the two ends of the annular airbag strip 1505 are lock buckles that can be set on the outside of the wrist to fix the needle assembly 15 again, thereby preventing the fixing tube 1501 and the hose 1502 of the needle assembly 15 from shaking due to external traction. At the same time, the hose 1502 is a flexible structure, and its slight shaking will not affect the syringe 9 on the rear side. During the blood drawing process, the micro motor 1105 drives the rotation of the threaded screw 1106, and then drives the lateral movement of the threaded sleeve 1107, so that the connecting plate 1109 on the lower side of the threaded sleeve 1107 can drive the movement of the pulling head 1103, the piston rod 1102 and the rubber stopper 1101, thereby realizing electric blood drawing with a stable rate without manual operation.

[0045] Since the connecting plate 1109 and the pull-out head 1103 are connected by bolts, the bolts can be removed to release the connection between the two when manual blood drawing is required. Then, the position of the connecting plate 1109 can be rotated sideways by the movable rotating shaft 1108 to prevent it from blocking the pull-out head 1103. Finally, the pull-out head 1103 can be used manually to draw blood. In this process, the position of the clamping frame 7 and the syringe 9 can be adjusted by lifting and lowering the telescopic rod 5, and the inclination angle of the clamping frame 7 and the syringe 9 can be adjusted by rotating the damping rotating shaft 6. The change is relatively flexible and convenient for medical staff to use. At the same time, the positioning block 801 and the rubber layer 802 on the inner side of the clamping frame 7 always position and fix the syringe 9 therein.

[0046] When the blood inside the syringe 9 is full, the control valve 13 can be closed, and then the rubber stopper 1101 can be pushed forward to allow the blood inside the syringe 9 to be injected into the collection tube 1204 through the connecting tube 1201 and the one-way valve 1202, thereby collecting the blood. At the same time, the setting of the one-way valve 1202 prevents the blood inside the collection tube 1204 from flowing back into the syringe 9. The setting of the sealing joint 1203 facilitates the disassembly and replacement of the collection tube 1204. Therefore, blood can be collected without removing the syringe 9. In this way, the entire use process of the blood extraction device for medical testing with anti-shake is completed.

Many modifications and variations will be apparent to those of ordinary skill in the art.
