Technical Field

[0001] The utility model provides a catheter dipping production device, belonging to the technical field of catheter dipping. Background Art

[0002] Catheters are of great significance in the field of medical technology, as they can achieve the functions of drug delivery and fluid control. In the field of catheter production technology, catheters need to be dip-coated to cover the outside of the catheters with a protective film; the surface of the catheter is often exposed to complex biological fluids or in contact with each other, and dip coating can provide a layer of anti-corrosion and anti-pollution protection to ensure the stability and reliability of the microcatheter; at the same time, catheter dip coating can improve its biocompatibility and reduce adverse effects on tissues and cells.

[0003] Since the catheter is relatively soft, when the catheter is dip-coated, the catheter is first fixed by using a fixed structure, and the catheter is placed in the dipping solution for a period of time and then taken out, and then the catheter is removed from the fixed structure; and then the new catheter to be dip-coated is fixed on the fixed structure. Therefore, when the catheter is dip-coated in batches, the work is often not continuous: the dip-coated catheter needs to be removed and a new catheter needs to be installed, which greatly reduces the efficiency of dip-coating.

[0028] Principle of the utility model

[0029] When using the utility model, first, the catheter 8 to be dipped is sleeved on the mounting rod 4; the limiting plate 9 and the mounting rod 4 are fixedly connected by the fixing screws 11, so that the catheter 8 is fixed to the mounting rod 4 by the limiting plate 9 and the limiting ring 7; after the catheter 8 is sleeved on the four groups of mounting rods 4, the dipping liquid is added to the dipping box 1; first, the catheter 8 on the lowest group of mounting rods 4 is dipped, and after the dipping is completed, the fixing rod 14 is pulled upward to disengage the fixing rod 14 from the fixing hole 10, and at the same time the fixing plate 16 compresses the rebound spring 17; operate the operating block 5 to make the rotating block 6 drive the rotating shaft 3 to rotate 90°, at this time, the mounting rod 4 vertically located in the dipping liquid is disengaged from the dipping liquid and becomes horizontal, and the mounting rod 4 originally in the horizontal state rotates into the dipping liquid, changes to a vertical state, and begins to be dipped. Therefore, the present application can put a new catheter 8 to be dipped into the coating liquid while taking out the catheter 8 that has been dipped, which can ensure the continuity of the dipping work and greatly improve the work efficiency. After rotating the operating block 5, loosen the fixing rod 14, and under the action of gravity and the rebound force of the rebound spring 17, the fixing rod 14 is inserted into the fixing hole 10, thereby fixing the rotating block 6 to prevent the rotating shaft 3 from rotating. When the catheter 8 that has been dipped is separated from the dipping liquid, the fan 2 can accelerate the curing of the dipping material and remove the solvent that may remain during the coating process. After drying for a period of time, remove the catheter 8 from the mounting rod 4, then put on a new catheter 8, and wait for the next rotation of the rotating shaft 3.
