Problems solved by technology

[0002] At present, the known method of coating the hydrophilic super-slip coating on the polymer guide tip is the dip coating method or the spray coating method. For the dip coating method, the thickness of the coating is difficult to control, and the catheter is pulled out from the coating solution after soaking. The coating liquid will move downward under the action of gravity, which will cause the thickness of the coating to increase as the catheter goes down. The coating cannot be coated evenly, and the thickness is difficult to control. Spraying sprays the coating material and adheres to the surface of the catheter , but this kind of coating method is easy to cause waste of coating and low adhesion during the atomization spraying process, and has high requirements for equipment and site environment, and the equipment cost is relatively high

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as Figure 1 to Figure 3 As shown, the coating equipment for the surface of polymer catheters includes:

[0023] The first carrier plate 1 is provided with a plurality of through holes 11 on the first carrier plate, five in the present embodiment; a plurality of ribs 12 are longitudinally provided on the side walls of each through hole; each rib in the present embodiment There is a smooth transition between them, and the surface of the convex rib is also a curved structure. A groove 13 is opened on the surface of the first carrier, and the groove 13 communicates with five through holes. The groove is a fluid replenishment channel for replenishing fluid into each through hole.

[0024] The base 2 is the supporting seat of the coating equipment. The middle part of the base 1 is provided with a liquid storage tank 21 , and the two ...

Abstract

The invention relates to a coating device used for a polymer conduit surface. The coating device is characterized in that: the coating device comprises a first support plate; the first support plate is provided with a plurality of through holes and a groove; the first support plate is connected to a first support pillar through a first driving mechanism; a liquid storage tank containing a coating liquid is disposed right below the first support plate; a second support pillar is disposed in parallel with the first support pillar; a second support plate is disposed at the second support pillar through a second driving mechanism; the second support plate is provided with a plurality of limiting holes used for limiting a conduit to be coated; the second support plate is provided with a clamping and fixing device used for positioning the conduit to be coated; the second support pillar is also provided with a baffle plate used for controlling the length penetrating through the second support plate of the conduit, and the baffle plate is rotatablely connected to the second support pillar. A novel coating method is provided. The thickness of the coating is uniform. The coating has strong adhesive force with the surface of the conduit. Waste of the coating liquid is avoided. The coating process is free of contamination to the inner wall of the conduit, thus guaranteeing production sanitation and safety.
