Example 2

As a second embodiment of the present invention, in order to facilitate the use of patients with different arm lengths, the present inventors have improved the first support frame 12 and the second support frame 13, as a preferred embodiment, as shown in fig. 4 to 8, the second support frame 13 has a receiving groove 2 communicating with the outside, the top wall and the bottom wall of the receiving groove 2 are both provided with a first sliding groove 20, the front side wall of the receiving groove 2 is also provided with a first threaded hole 21 communicating with the outside, the first threaded hole 21 is internally threaded with a screw rod 22, the end of the screw rod 22 is provided with a rotating disc 23, the first support frame 12 is provided with a fixed block 3 at a position facing the receiving groove 2, the fixed block 3 is located in the receiving groove 2 and is slidably connected with the receiving groove 2, the front side surface of the fixed block 3 is provided with a plurality of second threaded holes 30 arranged at equal intervals linearly, the screw rod 22 is in threaded connection with the second threaded holes 30, all be equipped with first slider 31 on the top surface and the bottom surface of fixed block 3, two first sliders 31 are located the coplanar, first slider 31 be located in the first spout 20 that corresponds with it and with sliding connection between the first spout 20, the inside of first support frame 12 still is equipped with second spout 4, set up the rectangular channel 40 that is linked together with the external world on the diapire of second spout 4, the top of the bracing piece 11 that is located first support frame 12 below passes rectangular channel 40 and close welding has second slider 5, sliding connection between bracing piece 11 and the rectangular channel 40, second slider 5 be located in second spout 4 and with sliding connection between the second spout 4.

In this embodiment, the positions of the two first sliding grooves 20 are opposite to each other, and the position of the first sliding block 31 corresponds to the position of the first sliding groove 20, so that the first sliding block 31 can correctly slide in the first sliding groove 20.

Specifically, be equipped with a plurality of on the carousel 23 and be the arc wall 231 of cyclic annular equidistant range, make when rotating carousel 23, can put into arc wall 231 with corresponding thumb, rotate carousel 23 more smoothly.

Further, the right side surface of the first slider 31 and the right side surface of the fixed block 3 are located on the same plane, and compared with the case that the first slider 31 is fixed at the middle position of the fixed block 3, when the first slider 31 is fixed at the end of the fixed block 3, the length of the fixed block 3 can be ensured to be the maximum when the fixed block 3 is pulled out towards the outside.

In addition, the size of the second sliding block 5 is matched with the size of the second sliding chute 4, and the left side surface and the right side surface of the second sliding block 5 are attached to the chute wall of the second sliding chute 4, so that the situation that the first support frame 12 shakes is avoided.

It is worth saying that, when taking fixed block 3 out to fixed block 3 and reaching the longest, at this moment, second slider 5 just in time contacts with the right side cell wall of second spout 4, when taking fixed block 3 wholly into and accomodate in the groove 2, at this moment, second slider 5 just in time contacts with the left side cell wall of second spout 4.

In this embodiment, through the storage groove 2 and the fixing block 3, when the length between the first support frame 12 and the second support frame 13 is not enough, the screw rod 22 can be firstly unscrewed, the fixing block 3 is drawn out from the storage groove 2 to a proper position, and then the fixing block 3 is fixed by using the screw rod 22, and the second slider 5 is slidably connected with the second sliding groove 4, so that the support rod 11 does not affect the normal movement of the first support frame 12, the process realizes the adjustment of the length between the first support frame 12 and the second support frame 13, and solves the problem that the length of a palm fixing support for general arterial puncture cannot be adjusted.

Example 3

As a third embodiment of the present invention, in order to adjust the heights of the first and second supporting

frames

12 and 13, the present inventor has modified the base plate 1 and the supporting rods 11, and as a preferred embodiment, as shown in fig. 9 to 11, a threaded sleeve 6 which is vertically distributed is further tightly welded at a position, facing the support rod 11, of the upper surface of the bottom plate 1, a third threaded hole 60 which is communicated with the outside is formed in the threaded sleeve 6, a screw 61 is in threaded connection with the third threaded hole 60, a fixed column 62 is tightly welded on the screw 61, a limit disc 63 is further tightly welded at the top end of the screw 61, the two screws 61 are connected through a transmission belt 64, the transmission belt 64 is located between the fixed column 62 and the limit disc 63, a bearing 65 is further tightly welded on the limit disc 63, and the tail end of the support rod 11 penetrates through the bearing 65 corresponding to the tail end of the support rod and is tightly welded with an inner ring of the bearing 65.

In this embodiment, the rod body of the screw 61 located between the limiting disc 63 and the fixing column 62 is not provided with an external thread, and the surface of the partial rod body is provided with an anti-slip layer to increase the friction between the partial rod body and the transmission belt 64, so that when one of the screw 61 is rotated, the transmission belt 64 can drive the other screw 61 to rotate.

Specifically, the outer ring of the bearing 65 and the limiting disc 63 are tightly welded, so that the inner ring of the bearing 65 can rotate, and the screw 61 can rotate.

In this embodiment, through the screw sleeve 6 and the screw rod 61, when one of the screw rods 61 is rotated, the screw rod 61 moves upwards or downwards, and simultaneously, the screw rod 61 rotates to drive the other screw rod 61 connected with the screw rod 61 through the transmission belt 64 to rotate, so that the two screw rods 61 are synchronously lifted or lowered, the effect of adjusting the heights of the first support frame 12 and the second support frame 13 is achieved, and the problem that the height of a palm fixing support for general arterial puncture cannot be adjusted is solved.

When the palm fixing bracket for arterial puncture is used, a patient places one punctured arm on the first support frame 12 and the second support frame 13, the first support frame 12 and the second support frame 13 can play a role of lifting the arm of the patient, then the two elastic belts 14 are respectively wound around the palm and the arm, the tail ends of the elastic belts 14 penetrate through the corresponding clamping grooves 151, then the stabbing surface magic tape 142 is adhered on the hair surface magic tape 141 to fix the arm of the patient, when the length between the first support frame 12 and the second support frame 13 is not enough, the screw rod 22 can be firstly unscrewed, the fixing block 3 is drawn out from the accommodating groove 2 to a proper position, then the screw rod 22 is used for fixing the fixing block 3 to adjust the length of the first support frame 12 and the second support frame 13, and finally, when one screw rod 61 is rotated, the screw rod 61 can move upwards or downwards, and the screw rod 61 is driven to rotate through the other screw rod 61 connected with the screw rod 61 through the transmission belt 64 when rotating, so that synchronous ascending or descending of the two screw rods 61 can be realized, the effect of adjusting the heights of the first support frame 12 and the second support frame 13 is achieved, and the problem that the patient is punctured even due to puncture failure caused by the fact that the arm of the patient moves and bounces when the artery puncture is performed on the patient is solved.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
