Description
Technical field
The utility model relates to seal wire manufacture field, especially dynamic sealing reservoirs and the painting of seal wire hydrophilic coating to cover
It is standby.
Background technique
Minimally Interventional Therapy technology and endoscopic technique have been carried out extensively in recent years as emerging Advances in Medicine,
Its process is under the monitoring of medical imaging device, and super-selective is by interventional medical device through naturally occurring blood vessel or intracoelomic cavity
Road is sent to many vitals and the position of human body, such as heart, liver, brain, kidney, digestive system and reproductive system, to carry out
The important technology and method of diagnosing and treating have the advantages that without performing the operation, wound is small, medical expense relative moderate.
In intervention and endoscopic diagnosis and therapeutic process, seal wire reaches target portion as all kinds of conduits of guiding and intervention apparatus
Position important instrument, be responsible for explore the way, lead deflection and guide move ahead etc. it is essential, act on it is irreplaceable, and belong to one
The medical treatment consumptive materials that secondary property uses, are usually made of core filaments and external coating, rigidity needed for core filaments play the role of support, outsourcing
Coating plays the role of guaranteeing that seal wire will not scratch cavity in use (diameter at the soft end of guidewire core wire is usually only
0.1mm or so).
In medical clinical practice, interventional guide wire enter human body using when can bring a series of reaction, such as coagulant property,
Bacterial adsorption and due to rub bring tissue damage, guidewire material other than must have due mechanical property,
Surface biocompatible be it is highly important, lubricity processing is done to interposing catheter surface, to the maximum extent mitigate patient pain
Hardship can simultaneously be effectively reduces the absorption of bacterial adhesion and protein, is the main way for improving material surface biocompatibility
Diameter.
And carrying out hydrophilic modifying to material surface is the main method for improving material surface lubricant nature, what is generallyd use in the past is
Lubricating oil (such as paraffin oil, silicone oil) is coated to seal wire surface, but this processing method it is poor to the lubricity effect of seal wire,
It is difficult to persistently and is unfavorable for operating.
Therefore, most medical instrument manufacturers generallys use with " PVP " as hydrophilic solution, is carried out in a manner of " dip-coating "
The technique of hydrophilic coating coating, and when dip-coating, since seal wire cannot be bent, the masking liquid copper of corresponding length is generally required with full
The requirement coated enough, and most of equipment can only often process the seal wire of 1.5 meters of length, also, to process 1.5 meters of long seal wires
Dipping system for, for the reservoir of dip-coating at 1.2 meters or so, this results in equipment will be at 3 meters or so, if to process more
Long seal wire, it is necessary to higher reservoir, and the height of equipment just needs increasing at double, equipment cost also mentions at double therewith
It is high.
Also have by the way of secondary u-turn dip-coating, that is, coat one time, after solidification, then seal wire reversed end for end, carry out secondary leaching
It applies, solidification, causes the cumbersome of process, efficiency reduces, and the uniformity of the clad formed after dip-coating respectively twice
It not can guarantee consistency with parameters such as thickness, the quality of final products caused to reduce, defect rate improves.

The small end opening for stating pilot hole 51 is greater than the diameter of the bar.
Therefore during the dynamic sealing reservoir 3 moves down, the guider 5 can be to positioned at its pilot hole 51
Interior seal wire carries out position restriction, to prevent from being in contact between adjacent seal wire, while the shape design of pilot hole 51 also can
It avoids generating interference to the hydrophilic coating having been coated on seal wire to the greatest extent, guarantees the effect of coating.
Further, since in the coating procedure of hydrophilic solution, it is possible that the phenomenon that hydrophilic solution drips, this will
The pollution for causing equipment internal environment is not easy to the maintenance of equipment, corresponding, as shown in Fig. 1, in the bottom plate of the cabinet 1
It is provided with dismountable pallet 9.
When being coated using above-mentioned seal wire hydrophilic coating coating equipment, process is as follows:
S1, it is suitable to be first moved to clamp assembly 2 and dynamic sealing reservoir 3 by control device control driving device
Clamp position, it is then artificial or one end of one group of seal wire is fixed on side by side on clamp assembly 2 by automation equipment.
S2, then by the other end of every seal wire 10 through a guider pilot hole and through one it is corresponding can shape
Become sealer 4 on through-hole 41 and extend to outside the dynamic sealing reservoir 3.
S3, then driving device makes the clamp assembly 2 and dynamic sealing reservoir 3 be moved upwards up to highest order.
S4, feeder starting gas supply, by air pressure make can deformation sealer 4 deformation with seal wire 10 be tightly connected, at this time
The bottom of the dynamic sealing reservoir 3 is sealing state, and hydrophilic solution can be injected.
S5 injects hydrophilic solution 20 in dynamic sealing reservoir 3, at this point, being located at the seal wire in dynamic sealing reservoir 3
Part is immersed in hydrophilic solution, so that the guidewire region immersed in hydrophilic solution is coated by hydrophilic solution.
S6 is moved downward to seal wire from dynamic sealing reservoir 3 according to the driving dynamic sealing reservoir 3 that imposes a condition and moves back
Out, during dynamic sealing reservoir 3 moves down, the position for immersing hydrophilic solution constantly changes, so that hydrophilic solution is not
The disconnected different location for being attached to seal wire, so that the coating of seal wire hydrophilic coating is done step-by-step under for upper right.
Further, after being coated with hydrophilic solution, it is also necessary to so that hydrophilic solution is formed by curing hydrophilic coating, it is corresponding, such as
Shown in attached drawing 1, it is provided with the highest order for being located at least in the clamp assembly 2 in the inner cavity of the cabinet 1 and the dynamic is close
Seal UV lamp band 7 between the lowest order of reservoir 3 and with the matched reflector 8 of the UV lamp band 7, the UV lamp band 7 is electrically
Connect the control device.
It is corresponding, further include S7 step during the dynamic sealing reservoir 3 moves down or later, opens UV lamp
Band 7 carries out hydrophilic coating solidification, and the UV cured specific time needs to be configured according to the characteristic of different hydrophilic solution.
Still there are many embodiment, all technologies formed using equivalents or equivalent transformation for the utility model
Scheme is all fallen within the protection scope of the utility model.
