Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figure 1 to Figure 3, this coating apparatus being used for polymeric catheter surface comprises:
First support plate 1, first support plate is provided with multiple through hole 11, is five in the present embodiment; The sidewall of each through hole is longitudinally provided with many convex tendons 12; Rounding off between each convex tendon in the present embodiment, and the surface of convex tendon is also arcuate structure.The surface of the first support plate offers groove 13, this groove 13 is all connected with five through holes.This groove is the fluid infusion passage of fluid infusion in each through hole.
Base 2, be the supporting seat of this coating apparatus, the middle part of base 1 is provided with reservoir 21, and the both sides of reservoir are respectively equipped with the first column 3 and the second column 4.Base 2 is provided with the first gauge tap 22 for controlling the first cylinder (not shown) work and the second gauge tap 23 for controlling the second cylinder operation.Second gauge tap 23 has two, and these two the second gauge taps 23 are connected in series, and when only having them to close up, the second cylinder (not shown) just can work simultaneously.
First column 3 is provided with can under external force along the first slide block 5 that the first column 3 slides up and down.First slide block 5 connects the piston rod of the first cylinder.First slide block 5 connects the first support plate 1 by head rod 51.First column 3 is also provided with the support 31 for locating liquid storage container 7.Liquid storage container 7 is spacing on support 31, and the outlet of liquid storage container 7 connects the groove 13 on the first support plate 1 by conduit 8, conduit 8 is provided with flow control valve (not shown).
Head rod 51 is provided with the spacing ring 52 for spacing conduit 8.
Second column 4 is provided with the piston rod that second slide block 6, second slide block 6 that can slide up and down along the second column 4 under external force connects the second cylinder.Second slide block 6 connects the second support plate 9 by the second connecting rod 61.
Second column 4 is also provided with the baffle plate 41 stretching out the length of the second support plate 9 for controlling conduit, this baffle plate 41 can rotate around the second column 4.
Second support plate 9 is provided with the spacing hole 91 that multiple confession conduit to be coated passes.Conveniently treat the clamping of coated catheters, the present embodiment is provided with multiple box body 92 on the upper surface of the second support plate 9, and each box body 92 and each spacing hole 91 one_to_one corresponding, the bottom surface of box body 92 is provided with the through hole consistent with spacing hole 91.Also be provided with two pieces of limited blocks, 93, two pieces of sides that limited block 93 is relative in each box body 92 and be provided with arc notch 94, two pieces of limited blocks 93 dock latter two arc notch and form the perforation consistent with spacing hole.Also being provided with two springs 95 in box body 92, conflicts respectively between the inner side edge and limited block 93 of box body in the two ends of spring.The through hole 11 of the first support plate and spacing hole 91 correspondence of the second support plate, suitable with the caliber of conduit to be coated.
Above-mentioned box body 92, limited block 93 and spring 95 form the clamping device of the present embodiment.
Above-mentioned box body also can replace by arranging groove on the second support plate.In the program, the perforation on spacing hole and above-mentioned box bottom coincides, and the bottom surface that limited block is arranged on groove is positioned at the top of spacing hole.
The operation principle of this coating apparatus is described below:
Before coating, first need the position of Height Adjustment first support plate relative to the first column of coating according to conduit, the height between the first support plate and reservoir liquid level is greater than the coated length of coated conduit.
Flap shutter, makes baffle plate be positioned at the below of the second support plate, the distance between baffle plate and the second support plate and catheter coatings height suitable.Push the limited block in box body aside, make conduit pass perforation and spacing hole expose to the second support plate.When conduit lower end touches baffle plate, unclamp limited block, limited block clamps respective conduit under the action of the spring automatically.
Outside flap shutter, makes baffle plate depart from and the overlapping, to facilitate moving up and down of the second support plate of the second support plate.
The each spacing hole on the second support plate is made to aim at each through hole on the first support plate.
Flow control valve in closure catheter for closing, injects coating solution in reservoir and liquid storage container.
Press the first gauge tap, return original position after making the first support plate move down immersion reservoir, the masking liquid in reservoir forms liquid film in the hole of the first support plate.Open flow control valve, the masking liquid in liquid storage container enters groove by conduit, then enters in each through hole, with to continuous supplementation masking liquid in each through hole.
Press two the second gauge taps, the second cylinder action drives the second support plate to move down together with conduit simultaneously, through the through hole on the first support plate and after reaching the limit of position, then at the drive initial position again next time of the second cylinder.
According to the number of times that the thickness determination conduit of required coating is reciprocal, until complete the coating layer thickness of regulation.In coating procedure, the flow of make-up solution controls by flow control valve.Conduit moves back and forth speed can adjust cylinder air inlet valve to realize control to movement rate according to coating result.
After coating, open limited block one by one, take off conduit, to coating dry solidification separately.
This coating apparatus forms fluid film by masking liquid surface tension, in the first support plate, masking liquid is supplemented continuously by transfusion catheter and infusion vessel, make to possess fluid film in the through hole of the first support plate always, by moving up and down of the second support plate, be the coated film that conduit to be coated passes in through hole, form the film coating of evenly coating at catheter surface; By reciprocating motion repeatedly, effectively ensure that uniformity and the uniformity of catheter coatings; And coating reusable edible, save masking liquid, and avoid the waste of masking liquid.
This equipment is without the need to external power supply simultaneously, and required drive is only compressed air, not only energy-conserving and environment-protective, and avoids masking liquid and reveal and the danger such as the equipment leakage short circuit that causes of splash.Being equipped with the first support plate and second support plate of different pore size, by changing the first support plate and the second support plate, carrying out the conduit of adaptive different size.
The design of two the second gauge taps, need both hands to operate simultaneously and just can start the second cylinder, guarantee the movement just carrying out the second support plate after operating personnel's both hands all leave working region, crush danger when avoiding single switch caused by false hit, production security obtains further raising.
