[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, this embodiment provides a staining apparatus for staining a sample 5 coated with a hydrophilic coating. For example, the sample 5 can be a catheter or guidewire. The apparatus includes at least: a frame 1, which can be constructed from steel columns and beams, having two parallel columns and several horizontal and vertical beams connected to the columns; a connecting platform 2, which can be a rectangular plate structure and is vertically and vertically mounted on the frame 1; and several connectors 201 for connecting the sample 5 to the bottom surface of the connecting platform 2. For example, connectors 201 can be connecting lugs for catheters, or hemostatic valves for guidewires. For example, connectors 201 can be installed on the connecting platform using a fixed or detachable connection. When fixed, they can be glued or partially embedded in the connecting platform 2; when detachable, they can be threaded. Connectors 201 can be evenly spaced in an array on the connecting platform 2. For example, when connector 201 is a connecting lug, the connecting lug on the connecting platform 2 can be of the same or different sizes to accommodate catheters of different sizes. For example, when connector 201 is a hemostatic valve, the connector on the hemostatic valve can be either a knob type or a push-button type. With a knob-type connector, tightening the knob locks the guidewire. With a push-button connector, pressing down the outer shell allows the guidewire to be inserted; once the guidewire is in, the cap pops up to lock it. Both types can be selected according to usage habits, and both achieve the desired guidewire fixation. The staining tank 3 stores staining reagents. The staining tank 3 is mounted on the frame 1 and located below the connecting platform 2. For example, the bottom of the frame 1 can form a frame structure through connecting crossbeams and longitudinal beams. The internal space of the frame structure serves as a receiving cavity 10. The staining tank 3 is detachably mounted in the receiving cavity 10. For example, the staining tank 3 can be inserted into or removed from the receiving cavity 10 from the top opening of the frame structure.

[0032] The top surface of the dyeing tank 3 is provided with several limiting holes 4 that connect to the internal space of the tank. The guide tube or guide wire to be dyed can be inserted into the dyeing tank 3 through the limiting holes 4. Moreover, due to the liftable design of the connecting platform 2, the guide tube or guide wire can be inserted to a suitable depth as needed to control the dyeing length, and even the entire wire can be dyed.

[0033] The dyeing apparatus provided in this embodiment includes a frame 1, a connecting platform 2 that is vertically adjustable at the top of the frame 1, and a dyeing tank 3 located at the bottom of the frame 1 below the connecting platform 2. Taking the workpiece 5 to be dyed as a guide tube or guide wire as an example, when dyeing is required, one end of the guide tube or guide wire can be temporarily fixed to the connecting platform 2 via a connector 201. Then, as the connecting platform 2 descends, the guide tube or guide wire can be inserted into the dyeing tank 3 through a limiting hole for dyeing. This configuration enables automated dyeing, allowing for batch dyeing compared to manual dyeing, improving dyeing efficiency, and avoiding inconsistent dyeing quality due to differences in operator skill levels.

[0034] like Figure 5 As shown, a partition 303 is provided inside the dyeing tank 3. For example, the partition 303 can be set along the height direction of the dyeing tank 3. The partition 303 divides the space inside the dyeing tank 3 into a dyeing area 301 on the left and a rinsing area 302 on the right. The limiting hole 4 on the top surface of the dyeing tank 3 is divided into a first limiting hole 401 and a second limiting hole 402. The first limiting hole 401 is adapted to the dyeing area 301, and the second limiting hole 402 is adapted to the rinsing area 302. The water outlet 602 of the rinsing device is connected to the rinsing area 302 and is used to rinse the guide tube or guide wire located in the rinsing area 302.

[0035] The staining area 301 may have a single large cavity or multiple independent small cavities. When the staining area 301 has a single large cavity, all the first limiting holes 401 are connected to the single large cavity. During staining, all catheters or guidewires share the staining agent in the large cavity.

[0036] When the staining area 301 has multiple independent small cavities, the first limiting hole 401 is configured to correspond one-to-one with each small cavity. During staining, each catheter or guidewire occupies a separate small cavity for staining. This configuration allows for the addition of different concentrations of staining agent to different small cavities according to staining requirements.

[0037] Specifically, the dyeing zone 301 can be, for example, part of the dyeing tank 3 structure, meaning the two are an integral unit. Alternatively, the dyeing zone 301 can be a separate structure from the dyeing tank 3, in which case it can be a box-shaped structure. The dyeing zone 301 can be modularly designed, with a mounting slot inside the dyeing tank 3 to accommodate it. In this case, the dyeing zone 301 can be detachably installed within the mounting slot of the dyeing tank 3. With this configuration, when the dyeing agent is insufficient, a new dyeing zone 301 can be directly replaced, making it more convenient to use.

[0038] The staining device also includes a rinsing device 6, which is disposed in the rinsing zone 302 and is used to rinse the catheter or guidewire located in the rinsing zone 302.

[0039] Preferably, two rinsing devices 6 are provided. The dyeing tank 3 has mounting holes 603 on two opposite side walls of the rinsing zone 302. Each mounting hole 603 houses one rinsing device 6. The outlet 602 of each rinsing device faces downwards at an angle to simultaneously rinse both sides of the guide tube or guide wire. For example, the rinsing device 6 can be a rectangular box-shaped structure. Each rinsing device 6 has several nozzles on its side facing the guide tube as its outlet 602. An inlet 601 can be provided on one of the other sides of the rinsing device 6, allowing water to enter the rinsing device 6 through the inlet 601 and flow out through the nozzles.

[0040] The bottom of the rinsing zone 302 is provided with a water outlet, and the wastewater generated after rinsing can be discharged from the water outlet 304 of the rinsing zone in a timely manner.

[0041] The dyeing apparatus also includes a scissor lift support 7; a top plate 8 is provided on the top of the frame 1, the connecting part of the scissor lift support 7 is connected to the top plate 8, and the moving part of the scissor lift support 7 is connected to the connecting platform 2. The scissor lift support 7 is used to drive the connecting platform 2 to perform lifting movements. For example, the scissor lift support 7 can be connected to the top plate 8 and the connecting platform 2 using bolts. For example, the scissor lift support 7 can be an existing scissor lift support 7, the working method of which is known to those skilled in the art and will not be described in detail here.

[0042] like Figure 6 As shown, the staining device also includes a slide rail 9 and a slider 12. The slide rail 9 is connected to the moving part of the scissor lift bracket 7, and the connecting platform 2 is slidably disposed on the side of the slide rail 9 facing away from the scissor lift bracket 7 via the slider 12. For example, the length direction of the slide rail 9 can be consistent with the length direction of the staining tank 3. When the slider 12 moves along the slide rail 9, it can drive the connecting platform 2 to switch between different positions above the staining area 301 and the rinsing area 302. For example, the connecting platform 2 and the slider 12 are detachably connected. For example, the top surface of the slider 12 and the connecting platform 2 can be connected by bolts. With this configuration, the connecting platform 2 with the corresponding specifications of connecting Luer 201 or hemostatic valve can be replaced for different specifications of catheters or guidewires.

[0043] An alarm is installed on the rack 1, which alerts the user that the test is over by ringing a bell or lighting a light.

[0044] The dyeing device can also be equipped with an intelligent electrical control box 11. The scissor lift bracket 7, slider 12, rinsing device 6, etc. can all be electrically connected to the intelligent electrical control box 11 to realize intelligent control of the working status of each part in sequence.

[0045] Taking the tubing as an example, during use, the tubing is installed onto the connecting platform 2 via a connecting Luer. Based on the length to be dyed, the immersion time, rinsing time, and drying time, the intelligent electrical control box 11 sets the descent height, holding time, rinsing time, and drying time. Then, the connecting platform 2 can be raised and lowered via the scissor lift bracket 7 for immersion dyeing. After the immersion time is over, the connecting platform 2 is raised to the set height via the scissor lift bracket 7, slides horizontally to the rinsing area 302 via the slide rail 9, and then lowers to the set height via the scissor lift bracket 7. The rinser 6 rinses to remove the floating dye, and then the scissor lift bracket 7 is raised to the original height for natural drying.

[0046] For example, the soaking time can be freely set from 0 min to 5 min with an accuracy of 1 second; the rinsing time can be freely set from 0 min to 5 min with an accuracy of 1 second; and the drying time can be freely set from 0 min to 5 min with an accuracy of 1 second.

[0047] In summary, the dyeing apparatus in this application allows for the dyeing of the entire product through a product connection method; it integrates the dyeing, rinsing, and drying steps into a single device, resulting in a higher degree of testing automation and improved testing efficiency.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
