[0034] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.

[0035] As described in the background, the current "impurity removal" method for medical devices not only has a slow impurity removal rate, but also easily affects the impurity removal effect of local parts of each medical device.

[0036] In view of this, the impurity removal device provided in the embodiments of the utility model can solve the above problems, which will be described in detail as follows.

[0037] Please refer to Figure 1 With Figure 2 The impurity removal device comprises a box body 1, a conveying pump 2 and a placing box 4, the bottom of the box body 1 is provided with a liquid inlet hole 10, the top of the box body 1 is provided with a liquid outlet hole 11, the conveying pump 2 is in communication with the liquid inlet hole 10, the placing box 4 is arranged in the interior of the box body 1, and a seepage hole 40 is arranged on each wall surface of the placing box 4. Wherein, the conveying pump 2 is used for pumping impurity removal liquid into the interior of the box body 1, the box body 1 is used for accommodating medical devices, the conveying pump 2 and the box body 1 are in communication through a liquid flow pipe 3, one end of the liquid flow pipe 3 is connected to the liquid inlet hole 10, and the other end of the liquid flow pipe 3 is connected to the conveying pump 2.

[0038] When the medical devices needing impurity removal are placed in the placing box 4, the delivery pump 2 is connected with the outside impurity removal liquid, the impurity removal liquid enters from the bottom of the box body 1 and is discharged from the top, the upward flow of the impurity removal liquid can completely immerse the medical devices, and the continuous flow of the impurity removal liquid can quickly contact the medical devices, thereby accelerating the dissolution of the solvent in the medical devices into the impurity removal liquid and improving the impurity removal rate. In addition, the medical devices are placed in the placing box 4, avoiding stacking together, so that the impurity removal liquid can contact each part of the medical devices, which is beneficial to ensure the impurity removal effect of each medical device.

[0039] The box body 1 is a closed structure, the inside of the box body 1 is hollow, and the shape of the box body 1 can be one of various shapes such as a cube or a cylinder. The box body 1 in the embodiment is a cube. The liquid inlet hole 10 is arranged at the bottom of the box body 1, and the liquid outlet hole 11 is arranged at the top of the box body 1 or around the side wall of the box body 1. The number of the liquid inlet hole 10 is one, and the number of the liquid outlet hole 11 is multiple. The liquid outlet hole 11 is arranged around the side wall of the box body 1. The liquid inlet hole 10 and the liquid outlet hole 11 are in communication with the inside of the box body 1. When the impurity removal liquid continuously flows into the inside of the box body 1 through the liquid inlet hole 10, the height of the impurity removal liquid in the inside of the box body 1 gradually increases until the medical devices in the inside of the box body 1 are completely immersed. When the liquid level of the impurity removal liquid in the inside of the box body 1 reaches the liquid outlet hole 11, the impurity removal liquid overflows from the liquid outlet hole 11, thereby forming a continuous liquid environment in the inside of the box body 1.

[0040] In order to repeatedly use the impurity removal liquid, a ring-shaped flow collection groove 12 is arranged on the outer side wall of the box body 1, and the flow collection groove 12 is located below the liquid outlet hole 11. A reflux pipe 6 is arranged between the flow collection groove 12 and the delivery pump 2. One end of the reflux pipe 6 is in communication with the flow collection groove 12, and the other end of the reflux pipe 6 is connected with the delivery pump 2. When the impurity removal liquid overflows from the liquid outlet hole 11 and flows into the flow collection groove 12, the impurity removal liquid in the flow collection groove 12 reenters the delivery pump 2 through the reflux pipe 6, and then the impurity removal liquid is pumped into the inside of the box body 1 again by the delivery pump 2.

[0041] In the embodiment, the flow collection groove 12 is sealingly connected with the outer wall of the box body 1, for example, by using sealing glue for bonding, to avoid liquid leakage. Meanwhile, the flow collection groove 12 is provided with a lower collection point. The impurity removal liquid flowing into the flow collection groove 12 flows to the collection point, which is convenient for collecting and using the impurity removal liquid. The connection part between the reflux pipe 6 and the flow collection groove 12 is the collection point, and the connection part is sealingly arranged.

[0042] When the impurity removal liquid is recycled for a long time, the solvent in the impurity removal liquid will increase, and the repeated use of the impurity removal liquid will affect the dissolution rate of the solvent in the medical device. Therefore, the box 1 is also provided with a concentration detection sensor, which is used to detect the concentration of the solvent in the impurity removal liquid. When the concentration of the solvent in the impurity removal liquid reaches a certain value, the delivery pump 2 is turned off, the used impurity removal liquid is replaced, and new impurity removal liquid is added to the box 1. The concentration sensor can be installed on the top of the box 1, and the detection probe of the concentration sensor can be inserted into the box 1 or immersed in the impurity removal liquid in the collecting tank 12. The type and category of the concentration sensor are not limited here, and the specific type and category should be selected according to the type of the solvent to be detected.

[0043] The delivery pump 2 can be selected from existing products on the market, and the specific model can be selected according to the size and use time of the box 1. In this embodiment, the delivery pump 2 is not limited.

[0044] In this embodiment, the impurity removal liquid can be water for injection, physiological saline or PBS solution. In other embodiments, appropriate impurity removal liquid can also be prepared according to the type of solvent to be removed.

[0045] In order to avoid the collision between the multiple medical devices in the box 1, which affects the accuracy of the medical devices, a placing box 4 is also provided in the box 1. The placing box 4 is used to place the medical devices, and the walls of the placing box 4 are provided with seepage holes 40, which communicate the inside of the placing box 4 with the inside of the box 1.

[0046] Specifically, the placing box 4 is connected by five rectangular plates with seepage holes 40 to form a frame structure. In use, the top of the frame structure is opened, and the medical devices are placed in the placing box 4. A grid plate 41 can also be provided in the placing box 4, which divides the space in the placing box 4 into multiple small spaces, and each small space contains a medical device. This can not only avoid the collision between multiple medical devices, but also further avoid the possibility of stacking of the medical devices, thereby ensuring the impurity removal effect. Of course, the grid plate 41 is also provided with multiple seepage holes 40 to ensure the flow of impurity removal liquid in each area.

[0047] Reference Figure 3 When the number of placing boxes 4 is multiple, a placing rack 5 can be provided in the box 1, and the placing boxes 4 are placed on the placing rack 5. The placing rack 5 includes multiple vertical columns 51 and multiple horizontal bars 52. The multiple horizontal bars 52 are connected with the multiple vertical columns 51 and form a limiting cavity 50. The multiple placing boxes 4 are stacked in the limiting cavity 50, and the number of limiting cavities 50 can also be multiple.

[0048] In the embodiment, the placing rack 5 is connected by four same columns 51 and twelve horizontal strips 52. The four columns 51 are arranged in parallel and at intervals. The two ends of the horizontal strips 52 are connected with the columns 51. Every four horizontal strips 52 are connected at the same height position of the column 51 to form a circle. In the height direction of the column 51, the adjacent horizontal strips 52 form the limiting cavity 50, and the placing box 4 is placed in the limiting cavity 50. A top hole plate 53 with holes is connected at the top end of the column 51. The top hole plate 53, the four columns 51 and the twelve horizontal strips 52 jointly build three limiting cavities 50. Of course, the inner bottom wall of the box body 1 is provided with the limiting fixed groove 13, and the bottom end of the column 51 is inserted into the limiting fixed groove 13, so as to prevent the placing rack 5 from moving in the box body 1. The bottom end of the column 51 and the limiting fixed groove 13 can be fixed by adhesive or can be placed without fixing, so that the placing rack 5 can be freely assembled and disassembled from the box body 1. The shapes of the column 51 and the horizontal strip 52 are not described in detail here, and can be selected according to the difficulty of obtaining the manufacturing materials.

[0049] If the size of the box body 1 is large, it is not conducive to the dispersion flow of the impurity removal liquid in the box body 1 to set an inlet hole 10 at the bottom of the box body 1, which may affect the impurity removal effect. Therefore, in the embodiment, a dispersion liquid outlet rack 7 is further arranged in the box body 1. The impurity removal liquid pumped is sprayed from different positions through the dispersion liquid outlet rack 7, so as to improve the impurity removal efficiency.

[0050] Reference Figure 4 and in combination Figure 1 The dispersion liquid outlet rack 7 comprises a main pipeline 70 and a plurality of branch pipelines 71. One end of the main pipeline 70 is closed, and the other end is open. The open end is inserted into the inlet hole 10. A plurality of round holes are formed in the circumferential side wall of the main pipeline 70. The plurality of branch pipelines 71 are respectively inserted into the plurality of round holes, so as to connect the plurality of branch pipelines 71 with the main pipeline 70. One end of each branch pipeline 71 is open, and the other end is closable. A plurality of liquid outlet holes 72 are formed in the side wall of the branch pipeline 71. When the impurity removal liquid enters the main pipeline 70 through the inlet hole 10, the impurity removal liquid flows into the plurality of branch pipelines 71 through the plurality of round holes. The impurity removal liquid is sprayed from the liquid outlet holes 72 of the branch pipelines 71, so as to increase the number of liquid outlet points of each part in the box body 1, which is conducive to the impurity removal effect. Of course, the liquid outlet holes 72 of the branch pipelines 71 are directed to the placing box 4.

[0051] In the embodiment, the dispersion liquid outlet rack 7 is arranged between the inner bottom wall of the box body 1 and the lowest placing box 4. The impurity removal liquid can flow through the plurality of stacked placing boxes 4 in sequence and then be discharged from the liquid outlet hole 11.

[0052] In order to avoid the growth of bacteria in the inner wall of the box 1 or the impurity removing liquid, the box 1 is further provided with a sterilization lamp 14, which can be selected as an ultraviolet lamp, and the ultraviolet lamp generates ultraviolet rays to sterilize the box 1 and the impurity removing liquid inside the box 1. The sterilization lamp 14 can be arranged at the top end of the inner wall of the box 1, or arranged outside the box. Of course, when the sterilization lamp 14 is arranged outside the box 1, the box 1 is transparent, so that the ultraviolet rays can smoothly penetrate the side wall of the box 1.

[0053] The impurity removing device of the embodiment of the utility model contacts the medical apparatuses rapidly through the continuously flowing impurity removing liquid, so as to accelerate the impurity removing rate, avoids that the medical apparatuses are stacked together, and guarantees the impurity removing effect of each medical apparatus.

[0054] The above is only a specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
