[0033] See attached document Figures 1-2 As shown, this utility model provides a technical solution: an arterial puncture auxiliary support device, including a support base 10 and at least two straps 20. The support base 10 forms a support space 11, which has a bottom wall 111 and a pair of side walls 112. The bottom wall 111 includes a first support portion 1111, a second support portion 1112 and a third support portion 1113. The second support portion 1112 and the third support portion 1113 are jointly constructed in an arc shape. At least two straps 20 are disposed on the pair of side walls 112, and the at least two straps 20 are arranged at intervals along the length direction of the support base 10.

[0034] For example, the strap 20 can be an elastic band, a snap fastener, or a Velcro strap. The bottom wall 111 can be made of rubber or textile fabric; for example, the rubber material can be silicone rubber or nitrile rubber.

[0035] According to this embodiment, before wrist puncture, the patient's palm and arm are inserted into the support space 11, and the arterial puncture site of the wrist is aligned with the second support portion 1112. The arm is fixed by a strap 20 near the first support portion 1111, and the palm is fixed by a strap 20 near the third support portion 1113. At this time, the strap 20 near the second support portion 1112 applies a downward force to the palm, causing the back of the hand to fit against the second support portion 1112 and the third support portion 1113; in particular, the second support portion 1112 keeps the wrist in an outward arched state, preventing the wrist from bending inward and making it impossible for medical personnel to perform the needle insertion.

[0036] Alternatively, the above method can also be applied to cubital fossa artery puncture. For example, the patient's upper and lower arms are inserted into the support space 11, and the cubital fossa is aligned with the second support portion 1112. At the same time, the strap 20 near the first support portion 1111 is used to fix the upper arm, and the strap 20 near the third support portion 1113 is used to fix the lower arm, thereby preventing bending within the cubital fossa that would prevent medical personnel from performing the needle insertion.

[0037] See attached document Figures 1-2 As shown, in some embodiments, portions of a pair of sidewalls 112 corresponding to the second support portion 1112 and the third support portion 1113 are both constructed in an arc shape.

[0038] According to this embodiment, by bringing the strap 20 closer to the palm than the third support portion 1113, it is easier to apply force to the palm and prevent the wrist from bending inward.

[0039] See attached document Figure 2 As shown, in some embodiments, the support base 10 has a receiving cavity 12, and a support pad 13 is provided in the receiving cavity 12 corresponding to the second support portion 1112.

[0040] According to this embodiment, the support pad 13 can enhance the supporting effect of the second support portion 1112 and prevent the second support portion 1112 from sinking downward.

[0041] See attached document Figures 3-4 As shown, in some embodiments, an adjustment mechanism 30 is included. The adjustment mechanism 30 is disposed between the bottom wall 111 of the accommodating cavity 12 and the support pad 13. The adjustment mechanism 30 includes a support tube 31, a lead screw 32, a threaded tube 33, a drive assembly 34, and a guide assembly 35. The support tube 31, the lead screw 32, and the threaded tube are arranged sequentially facing the support pad 13. The end of the support tube 31 facing away from the lead screw 32 contacts the support pad 13. The lead screw 32 is threadedly engaged with the threaded tube 33. The output end of the drive assembly 34 is connected to the lead screw 32, and the drive assembly 34 is used to drive the lead screw. 32. Rotation: The guide assembly 35 includes a first connecting sleeve 351, a second connecting sleeve 352, and a guide rod 353. The first connecting sleeve 351 is sleeved on the threaded tube 33, and the second connecting sleeve 352 is sleeved on the support tube 31. The second connecting sleeve 352 has at least two guide holes 3521, and the at least two guide holes 3521 are arranged at intervals around the axis of the second connecting sleeve 352. The number of guide rods 353 is related to the number of guide holes 3521. One end of the guide rod 353 passes through the guide hole 3521 in a corresponding manner and is connected to the first connecting sleeve 351.

[0042] For example, the drive component 34 can be a small servo motor or a small stepper motor, etc.; when the drive component 34 is a small servo motor or a small stepper motor, the drive component 34 can be housed inside the support tube 31. The lead screw 32 and the support tube 31 can be connected by bearings, etc.

[0043] According to this embodiment, the lead screw 32 is driven to rotate by the drive assembly 34, so that the lead screw 32 drives the threaded tube 33 to move in the vertical direction. At the same time, the guide rod 353 moves along the guide hole 3521, thereby adjusting the height of the support pad 13 and thus adjusting the degree of outward arching of the wrist to facilitate operation by medical staff.

[0044] See attached document Figure 3As shown, in some embodiments, the drive assembly 34 includes a transmission unit 341 and a drive shaft 342. The transmission unit 341 is mounted on the lead screw 32, one end of the drive shaft 342 is connected to the transmission unit 341, and the other end of the drive shaft 342 passes through a side wall 112 of the accommodating cavity 12 and is exposed outside the support base 10. Optionally, the transmission unit 341 includes at least two bevel gears or worm gears and a worm.

[0045] For example, when the transmission unit 341 includes two bevel gears, one bevel gear is sleeved on the lead screw 32, and the other bevel gear is sleeved on one end of the transmission shaft 342; when the transmission unit 341 includes a worm gear and a worm, the worm gear is sleeved on the lead screw 32, and the connecting end of the worm is connected to one end of the transmission shaft 342.

[0046] See attached document Figure 3 As shown, in some embodiments, a knob 40 is included, which is sleeved on the other end of the drive shaft 342.

[0047] According to this embodiment, force is applied to the drive shaft 342 by the knob 40, thereby providing convenience for medical staff.

[0048] Preferably, the support pad 13 is made of plastic.

[0049] For example, the plastic material can be polyphenylene sulfide plastic or polyvinyl chloride, etc.

[0050] According to this embodiment, by utilizing the relatively hard properties of plastic, bending of the second support portion 1112 can be avoided as much as possible when force is applied, thereby improving the support capacity of the second support portion 1112.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
