Abstract
Description
Technical Field
[0001] The utility model relates to the field of brushing equipment, in particular to a hydrophilic coating brushing equipment for medical guide wires. Background Technique
[0002] During the interventional treatment process, the medical guide wire plays an irreplaceable role in guiding, positioning and transmitting, and can assist the catheter to accurately enter various tiny blood vessels in the human body, guiding the catheter to reach the lesion site in the body smoothly for local diagnosis and treatment.
[0003] The surface of a simple medical metal guide wire and a metal micro-spring has a certain degree of hydrophobicity and a high surface friction coefficient. When directly used, it is extremely easy to have astringency, which will affect the actual guiding function, and in severe cases, it will damage the inner wall of the blood vessel. Introducing a relatively thin hydrophilic lubricating coating on the surface of the metal guide wire or metal spring can reduce blood vessel damage when the guide wire moves, thereby reducing unnecessary pain and damage to the patient, and can ensure that the surface of the guide wire has a lower friction coefficient, making it easy to achieve the tracking and smoothness of the guide wire, and effectively reducing the operation difficulty of doctors.
[0004] At present, the hydrophilic coating on the medical guide wire generally adopts a simple dipping method. After dipping, the hydrophilic coating needs a long time to dry, which affects the production efficiency, and dipping cannot well control the thickness and uniformity of the hydrophilic coating. Content of the Utility Model
[0005] Therefore, it is necessary to provide a hydrophilic coating brushing equipment for medical guide wires to solve the problems of poor control of the thickness of the hydrophilic coating on the medical guide wire and low production efficiency.
[0006] To achieve the above object, the utility model provides a hydrophilic coating brushing equipment for medical guide wires, including:

[0008] A brushing module, the brushing module includes a brushing bracket, a plurality of groups of brushing components and a brushing driving device. The brushing components and the brushing driving device are both arranged on the brushing bracket. Each group of the brushing components includes two relatively arranged brushing liquid adsorption blocks. The brushing driving device is used to drive the two brushing liquid adsorption blocks in the same group to move towards or away from each other, and the medical guide wire is located between the two brushing liquid adsorption blocks in the same group;

The two brushing liquid adsorption blocks of the brushing assembly are respectively a fixed adsorption block and a movable adsorption block. The movable adsorption block and the fixed adsorption block are respectively fixed on the movable plate and the brushing bracket.
[0011] During the brushing of the medical catheter, the position of the fixed adsorption block is relatively fixed, while the movable adsorption block fixed on the movable plate moves towards the fixed adsorption block under the drive of the brushing driving device. The brushing driving device drives multiple groups of brushing assemblies to brush the medical guide wire through the movable plate at the same time.
[0012] Further, each group of the brushing assemblies includes a positioning rod and two mounting seats. The movable adsorption block and the fixed adsorption block of the same group are respectively fixed on the movable plate and the brushing bracket through the mounting seats. The positioning rod is fixed on the side of one mounting seat, and a positioning hole corresponding to the positioning rod is provided on the other mounting seat. The cooperation of the positioning hole and the positioning rod ensures the accurate alignment when the brushing liquid adsorption blocks move towards each other.
[0013] Further, each group of the brushing assemblies includes two positioning rods. One ends of the two positioning rods are respectively fixed to one mounting seat, and the two positioning rods are parallel to each other. The medical guide wire is threaded between the two positioning rods.
[0014] While guiding the relative movement of the two brushing liquid adsorption blocks, the two positioning rods define the position of the medical guide wire, which is beneficial to the progress of the brushing process.
[0015] Further, the brushing driving device is a synchronous belt module. The synchronous belt module is connected to the side of the movable plate through a connecting plate. The brushing bracket is provided with a sliding linear guide, and the movable plate is slidably arranged on the sliding linear guide.
[0016] The synchronous belt module drives the movable plate to perform linear motion, and the sliding linear guide on the brushing bracket is used to ensure the stability of the movement of the movable plate.
[0017] Further, the fixture includes a fixed seat, and a fixed cavity is provided on the fixed seat. Elastic plates are inclinedly arranged on both sides of the fixed cavity, and buffer pads are provided on the inner sides of the elastic plates.
[0018] During use, one end of the medical guide wire is inserted into the fixed cavity, and the buffer pads on the inner sides of the elastic plates clamp and fix the medical guide wire.
[0019] Further, the fixed bracket is provided with a plurality of connecting columns, and one ends of the connecting columns are threadedly connected to the fixed seat. The threaded connection between the fixed seat and the connecting columns facilitates disassembly and replacement.
[0020] Further, the lifting module includes a driving motor and two belt assemblies. Each belt assembly includes a conveyor belt, and both ends of the conveyor belt are respectively wound around a rotating shaft. The driving motor is connected to the rotating shaft of the belt assembly. Both ends of the fixed bracket are respectively connected to the two conveyor belts of one lifting module, and both ends of the brushing bracket are respectively connected to the two conveyor belts of the other lifting module.
[0021] The above technical solution has the following beneficial effects:
[0022] In the present utility model, the fixed bracket adjusts its height on the frame through one lifting module, and the other lifting module enables the brushing assembly to lift and slide along the surface of the medical guide wire. The proximity of the two brushing liquid adsorption blocks can comprehensively brush the medical guide wire therein. The brushing driving device drives the two brushing liquid adsorption blocks to fit and separate. Through the cooperation of the fixed module and the brushing module in the present utility model, the coating of the surfaces of multiple medical guide wires can be quickly completed, effectively improving the production efficiency. The drying time of brushing is faster than that of dip coating, and the thickness of the hydrophilic coating formed on the medical guide wire can be controlled by the number of times of brushing by the brushing module.

[0036] To describe in detail the technical content, structural features, achieved objectives and effects of the technical solution, the following is a detailed description in conjunction with specific embodiments and with reference to the accompanying drawings.
[0037] Please refer to Figure 1-8 , this embodiment discloses a hydrophilic coating brushing device for a medical guide wire, which includes a fixing module 1, a brushing module 2 and a machine frame 3.
[0038] The fixing module 1 includes a fixing bracket 11 and a plurality of clamps 12 fixed on the fixing bracket 11. The clamps 12 are used to fix one end of the medical guide wire 4.
[0039] In this embodiment, the fixing bracket 11 may include six groups of clamps 12. The six groups of clamps 12 are arranged in a row on the fixing bracket 11. The number of clamps 12 corresponds to the number of brushing assemblies 22, so that the brushing device can brush the coatings on multiple medical guide wires 4 at the same time, improving the efficiency.
[0040] The clamp 12 includes a fixing base 121. A fixing cavity 122 is provided on the fixing base 121. Inclined elastic plates 123 are provided on both sides of the fixing cavity 122. A buffer gasket 124 is provided on the inner side surface of the elastic plate 123.
[0041] During use, one end of the medical guide wire 4 is inserted into the fixing cavity 122, and the medical guide wire 4 is clamped by the self-elasticity of the elastic plate 123.
[0042] In some embodiments, a positioning ring 125 is connected to the fixing base 121. The positioning ring 125 is located at the front end of the fixing cavity 122. The medical guide wire 4 passes through the positioning ring 125 and then is inserted into the fixing cavity 122 for clamping.
[0043] In this embodiment, the fixed bracket 11 is provided with six connecting columns 13, and one end of each connecting column 13 is threadedly connected to the fixed seat 121. The threaded connection between the fixed seat 121 and the connecting column 13 facilitates disassembly and replacement.
[0044] The brushing module 2 includes a brushing bracket 21, six groups of brushing components 22, and a brushing driving device 23. The brushing components 22 and the brushing driving device 23 are both arranged on the brushing bracket 21. Each group of brushing components 22 includes two relatively arranged brushing liquid absorption blocks 221. The brushing driving device 23 is used to drive the two brushing liquid absorption blocks 221 in the same group to move towards each other or in opposite directions. The medical guide wire 4 is located between the two brushing liquid absorption blocks 221 in the same group.
[0045] In some embodiments, the brushing liquid absorption block 221 is a sponge block for absorbing the brushing liquid. During use, the brushing liquid is sucked by a rubber head dropper and dripped onto the sponge block. When the two brushing liquid absorption blocks 221 clamp the medical guide wire 4 relatively, the brushing liquid is extruded and brushed onto the surface of the medical guide wire 4.
[0046] The brushing module 2 includes a movable plate 224. The movable plate 224 is drivingly connected to the brushing driving device 23. The two brushing liquid absorption blocks 221 of the brushing component 22 are respectively a fixed absorption block 222 and a movable absorption block 223. The movable absorption block 223 and the fixed absorption block 222 are respectively fixed on the movable plate 224 and the brushing bracket 21.
[0047] During the brushing of the medical catheter, the position of the fixed absorption block 222 is relatively fixed, while the movable absorption block 223 fixed on the movable plate 224 moves towards the fixed absorption block 222 under the drive of the brushing driving device 23. The brushing driving device 23 drives multiple groups of brushing components 22 to brush the medical guide wire 4 through the movable plate 224 at the same time.
[0048] Each group of brushing components 22 includes a positioning rod 225 and two mounting seats 226. The movable absorption block 223 and the fixed absorption block 222 in the same group are respectively fixed on the two mounting seats 226. The two mounting seats 226 are respectively fixed on the movable plate 224 and the brushing bracket 21. The positioning rod 225 is fixed on the side of one mounting seat 226, and a positioning hole corresponding to the positioning rod 225 is provided on the other mounting seat 226. The cooperation between the positioning hole and the positioning rod 225 ensures the accurate alignment when the brushing liquid absorption blocks 221 move towards each other.
[0049] Each group of brushing components 22 includes two positioning rods 225. One ends of the two positioning rods 225 are respectively fixed to one mounting seat 226. The two positioning rods 225 are parallel to each other, and the medical guide wire 4 passes through between the two positioning rods 225.
[0050] While guiding the relative movement of the two brushing liquid absorption blocks 221, the two positioning rods 225 limit the position of the medical guide wire 4, which is beneficial to the progress of the brushing process.
[0051] In some embodiments, one positioning rod 225 is a long rod and the other positioning rod 225 is a short rod. When the two mounting seats 226 move away from each other, the free end of the long rod remains within the positioning hole, while a gap is formed between the free end of the short rod and the side surface of the mounting seat 226. At this time, it is convenient to insert the medical guide wire 4.
[0052] The brushing driving device 23 is a synchronous belt module. The synchronous belt module is connected to the side surface of the movable plate 224 through a connecting plate 24. The brushing bracket 21 is provided with a sliding rail 25, and the movable plate 224 is slidably arranged on the sliding rail 25.
[0053] The synchronous belt module drives the movable plate 224 to perform linear motion, and the sliding rail 25 on the brushing bracket 21 is used to ensure the stability of the movement of the movable plate 224.
[0054] Two lifting modules 31 are provided on the frame 3, and the fixed bracket 11 and the brushing bracket 21 are respectively connected to one group of lifting modules 31.
[0055] The lifting module 31 includes a driving motor 311 and two belt assemblies. Each belt assembly includes a transmission belt 312. The two ends of the transmission belt 312 respectively bypass a rotating shaft 313. The driving motor 311 is connected to the rotating shaft 313 of the belt assembly. The two ends of the fixed bracket 11 are respectively connected to the two transmission belts 312 of one lifting module 31, and the two ends of the brushing bracket 21 are respectively connected to the two transmission belts 312 of the other lifting module 31.
[0056] In some embodiments, sensors are provided at the ends of the fixed bracket 11 and the brushing bracket 21. When they are lifted to the extreme distance at the upper and lower ends, the operator can be reminded through a prompting system.
[0057] The use process of the present utility model is as follows:
[0058] 1. The fixture 12 can be first removed from the fixed bracket 11. One end of the medical guide wire 4 is inserted into the fixed cavity 122 so that the buffer gasket 124 clamps and fixes the medical guide wire 4, and then the fixture 12 is fixed to the fixed bracket 11 again;
[0059] 2. The lifting module 31 raises the position of the fixed bracket 11 so that the medical guide wire 4 is vertically suspended, and the position of the medical guide wire 4 is adjusted so that it is just located between the two brushing liquid adsorption blocks 221;
[0060] 3. The brushing liquid is dropped on the two brushing liquid adsorption blocks 221, and the lifting module 31 raises the brushing bracket 21 to the starting point of brushing the medical guide wire 4;
[0061] 4. After that, the synchronous belt module drives the movable plate 224, so that the fixed adsorption block 222 and the movable adsorption block 223 are mutually attached. At this time, the medical guide wire 4 is located between the fixed adsorption block 222 and the movable adsorption block 223;
[0062] 5. The lifting module 31 drives the brushing bracket 21 to descend, and the brushing liquid on the fixed adsorption block 222 and the movable adsorption block 223 is extruded and brushed onto the surface of the medical guide wire 4.
[0063] During brushing, according to the requirements of the coating thickness, the medical guide wire 4 can be brushed multiple times.
[0064] In the present utility model, the fixed bracket 11 adjusts its height on the frame 3 through a lifting module 31. Another lifting module 31 can make the brushing assembly 22 lift and slide along the surface of the medical guide wire 4. The approach of the two brushing liquid adsorption blocks 221 can brush the medical guide wire 4 therein comprehensively. The brushing driving device 23 drives the attachment and separation of the two brushing liquid adsorption blocks 221. Through the cooperation of the fixed module 1 and the brushing module 2 in the present utility model, the coating of the surfaces of multiple medical guide wires 4 can be quickly completed, effectively improving the production efficiency. The drying time of brushing is faster than that of dip coating, and the thickness of the hydrophilic coating formed on the medical guide wire 4 can be controlled by the number of times of brushing by the brushing module 2.
