Technical Field

[0001] The utility model relates to the technical field of lifting tables, in particular to an electric lifting table. Background Art

[0002] PICC catheterization is clinically known as peripherally inserted central venous catheter, which is a relatively large operation. It is a central venous catheter placed in the peripheral vein of the arm for puncture, with the head end located in the superior vena cava or subclavian vein and the tail end located in the patient's upper limb. The burial time is also relatively long, which may be up to several years. It can be used to infuse various drugs, reduce the pain caused to patients by frequent venous punctures, and avoid local tissue necrosis caused by stimulating drugs that damage peripheral veins and chemotherapy drug extravasation, solving the problem of infusion for patients with poor peripheral vascular conditions. It has been widely used in clinical practice.

[0003] Before cannulation, the patient's entire arm on the cannulation side must be disinfected. During disinfection, the patient's entire arm must be removed from the diagnostic bed, and both the puncture site and the skin beneath the arm must be disinfected. After disinfection, a sterile treatment drape is placed over the arm before the disinfected arm is lowered. During the clinical procedure, an assistant is required to help lift the patient's arm, suspending it in the air to facilitate disinfection. Assisting in lifting the patient's arm during surgery not only increases the workload of medical staff but can also lead to unstable support, impacting treatment effectiveness.

[0004] Therefore, an electric lift table has become a problem that needs to be solved urgently by the whole society. Utility Model Content

[0020] Example 1:

[0021] When the utility model is in use, by pressing the power control button on the control panel 11, the drive motor 3 installed in the beam 2 is started, and the drive motor 3 drives the first guide gear 6 to rotate. Since the first guide gear 6 and the second guide gear 7 are engaged, the rotation of the first guide gear 6 drives the engaged second guide gear 7 to start rotating, and the second guide gear 7 drives the screw rod 4 to move up and down along the thread of the guide hollow shaft 5. The screw rod 4 moves up and down and drives the first telescopic support frame 8 at the top to move up and down through the fixed plate 15, thereby realizing the extension and retraction of the first telescopic support frame 8, the second telescopic support frame 9 and the third telescopic support frame 10, and completing the lifting and lowering of the electric lifting table.

[0022] Before adjusting the lifting height, you can first move it to the side of the operating bed, place the patient's arm on the supporting table 1, and then adjust the height of the electric lifting table through the control panel 11. Adjusting it to a suitable height can provide convenience for the medical staff's surgical operation process. There is no need to manually support the patient's arm or limb. The above-mentioned electric lifting table can improve the stability of the patient's arm or limb support.

[0023] In order to facilitate the rotation of the screw rod, the screw rod 4 is rotatably connected to the fixing plate 15 .

[0024] Example 2:

[0025] The column component includes a first telescopic support frame 8, a second telescopic support frame 9 and a third telescopic support frame 10, and the first telescopic support frame 8, the second telescopic support frame 9 and the third telescopic support frame 10 are sequentially assembled together from top to bottom.

[0026] When this embodiment is in use, the column component includes three groups of telescopic support frames. The driving motor 3 drives the screw rod 4 to rotate, and the screw rod 4 is lifted and lowered to drive the first telescopic support frame 8 at the top to lift and lower, thereby realizing the lifting of the first telescopic support frame 8, the second telescopic support frame 9 and the third telescopic support frame 10. The lifting of the above-mentioned column components drives the support table top 1 to realize the lifting process, which is simple to operate and has strong practicality.
