DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0023] Please refer to Figure 1-5 The application provides a technical solution:

[0024] Embodiment one:

[0025] A centrifugal medical utensil sterilization device, comprising a centrifugal rotating cylinder 1, the centrifugal rotating cylinder 1 rotates around its own axis, the axis of the centrifugal rotating cylinder 1 is movably connected to an eccentric shaft 2, the eccentric shaft 2 is movably connected to an eccentric rotating disc 3, and the eccentric rotating disc 3 rotates around its own axis under the drive of a power mechanism;

[0026] A disinfection cabin 4 is provided inside the centrifugal rotating cylinder 1. A wall-mounted plane 5 for medical vessels 8 is provided on one side of the disinfection cabin 4. Several groups of racks 6 are provided on the wall-mounted plane 5. A sealing rubber layer 7 is also provided in the disinfection cabin 4 on one side of the wall-mounted plane 5. Several groups of racks 6 are arranged obliquely upward. The medical vessels 8 are tilted downward without external force. During the rotation of the centrifugal rotating cylinder 1, the medical vessels 8 are pressed against the wall-mounted plane 5 by the centrifugal force. The wall-mounted plane 5 where the several groups of racks 6 are located are provided with negative pressure holes 9 and injection holes 10. The negative pressure holes 9 are used to extract the internal gas to form a negative pressure space when the medical vessel 8 is pressed against the wall-mounted plane 5. The injection hole 10 is used to add disinfectant to the medical vessel 8. A spray head 11 is also provided on the inside of the disinfection cabin 4 for spraying and cleaning the outside of the medical vessel 8.

[0027] In this embodiment, the sterilization chamber 4 formed inside the centrifugal rotating cylinder 1 is used to store medical instruments 8. The medical instruments 8 are placed on the wall-mounted plane 5 through a plurality of sets of hangers 6. The plurality of hangers 6 are arranged obliquely upward. When the medical instruments 8 are hung on the hangers 6, without the action of external force, the medical instruments 8 are in a downwardly open and tilted state. Figure 5 In this state, the disinfectant inside the medical vessel 8 can flow out from the open bottom, but the centrifugal rotating cylinder 1 is in a rotating state, and the medical vessel 8 is tightly attached to the wall-mounted plane 5 under the action of centrifugal force. Since the sealing rubber layer 7 provided on the wall-mounted plane 5 seals the open edge of the medical vessel 8, the gas inside the medical vessel 8 is discharged outward through the negative pressure hole 9 to form a negative pressure space. At this time, the medical vessel 8 is tightly attached to the wall-mounted plane 5, and the disinfectant is filled into each medical vessel 8 through the injection hole 10. In the process of the medical vessel 8 performing planetary rotation with the centrifugal rotating cylinder 1, the disinfectant is discharged under the centrifugal force. Under the action of the centrifugal rotating cylinder 1, the medical vessel 8 is vibrated inside, thereby immersing and disinfecting the medical vessel 8. At the same time, the external spray head 11 is cooperated to perform external spray disinfection of the medical vessel 8. After the liquid in the disinfection chamber 4 reaches a certain height, during the rotation of the centrifugal rotating cylinder 1, the disinfectant can immerse and vibrate the outside of the medical vessel 8 for disinfection. Through the combined operation of shaking, spraying and soaking, the inside and outside of the medical vessel 8 can be effectively disinfected in all directions to ensure the safety of the medical device during use. A sealing cover 19 is provided on the upper part of the centrifugal rotating cylinder 1 and the protective cover 12 to prevent the internal disinfectant from splashing out during operation.

[0028] Example 2:

[0029] In this embodiment, the centrifugal rotating cylinder 1 is movably arranged inside the protective cover 12, the eccentric rotating disc 3 is movably arranged at the bottom of the protective cover 12, the inner wall of the protective cover 12 is provided with an inner tooth ring 13, the outer side of the centrifugal rotating cylinder 1 is fixedly provided with an outer tooth ring 14 matched with the inner tooth ring 13, the centrifugal rotating cylinder 1 rotates around the shaft in the meshing process of the inner tooth ring 13 and the outer tooth ring 14, the eccentric rotating disc 3 in this embodiment rotates under the driving of an external power mechanism, the motor-driven structure is a common structure in the prior art, which will not be described here. The rotation of the eccentric rotating disc 3 drives the centrifugal rotating cylinder 1 to rotate around the shaft. In the rotation process of the centrifugal rotating cylinder 1 around the shaft of the eccentric rotating disc 3, the meshing of the inner tooth ring 13 and the outer tooth ring 14 promotes the rotation of the centrifugal rotating cylinder 1 around its own shaft. In this way, the centrifugal rotating cylinder 1 can rotate around the shaft of the eccentric rotating disc 3 and rotate itself, thereby realizing the oscillation, immersion and flushing of the disinfectant on the medical utensils 8 by using the change of centrifugal force.

[0030] Embodiment three:

[0031] In this embodiment, the negative pressure holes 9 are communicated with the negative pressure pump 16 through the negative pressure channels 15 formed inside the centrifugal rotating cylinder 1, the liquid injection holes 10 are communicated with the electromagnetic valve 18 through the liquid injection channels 17 formed inside the centrifugal rotating cylinder 1, and the electromagnetic valve 18 is arranged at the bottom of the centrifugal rotating cylinder 1. When a negative pressure space is formed inside the medical utensils 8, the disinfectant in the disinfection cabin 4 above the electromagnetic valve 18 enters the inside of the medical utensils 8 under the action of negative pressure when the electromagnetic valve 18 is opened. The negative pressure environment in the medical utensils 8 is realized by the operation of the negative pressure pump 16. When the negative pressure environment in the medical utensils 8 is realized, the electromagnetic valve 18 is opened, and the negative pressure environment attracts the disinfectant in the disinfection cabin 4 into the medical utensils 8. In this way, the disinfectant is added into the medical utensils 8. Further, since the pressure inside the medical utensils 8 is consistent from top to bottom, when the electromagnetic valve 18 is opened, the liquid will preferentially enter the bottom medical utensils 8. Therefore, in order to ensure that the amount of liquid in each medical utensil 8 is consistent, the diameters of the liquid injection holes 10 are gradually reduced from top to bottom. In this way, the flow rate of the bottom liquid injection hole 10 is limited to prevent the bottom medical utensil 8 from falling off due to overfilling of disinfectant, while the upper disinfectant filling amount is small. By reasonably setting the diameters of the liquid injection holes 10, the unit flow rates of the liquid injection holes 10 are approximately the same, and the disinfectant filling amount is preferably 1 / 2 of the internal space of the medical utensils 8, which can not only ensure the realization of negative pressure adsorption, but also achieve good oscillation disinfection effect. When the disinfection is completed, the centrifugal rotating cylinder 1 is stationary, and the medical utensils 8 are inflated again by the negative pressure pump 16 at this time. The medical utensils 8 are in the state shown in the drawings under the restriction of their own gravity and the structure of the hanging frame 6. Figure 5When the sterilization is completed, the liquid is discharged through the drain hole 21, the bottom of the protection cover 12 is provided with a hollow channel 22 for the discharge of the cleaning liquid, the plurality of spray heads 11 are communicated with the spray channel 20, the spray channel 20 is communicated with the external liquid injection pump through the liquid injection channel of the eccentric rotating shaft 2 and the eccentric rotating disc 3, the liquid is injected into the spray channel 20 through the external liquid injection pump, and the sterilization liquid finally enters the sterilization cabin 4 through the spray head 11.

[0032] While the embodiments of the application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
