Description

Technical Field

[0001] The present invention specifically relates to a storage cabinet with a sterilization structure. Background Art

[0002] In a hospital, if medical devices are stored in an ordinary storage cabinet, they are extremely vulnerable to contamination by microorganisms such as bacteria and viruses. Cross-infection may occur when they are used again, seriously threatening the health of patients. Therefore, most current medical devices are stored in a storage cabinet with a sterilization structure. Through the sterilization structure in the storage cabinet, bacteria, viruses and other microorganisms in the storage space can be effectively killed, providing a safe and hygienic storage environment for medical devices.

[0003] For example, the Chinese invention patent with the patent number CN111035777B provides a smart storage device for disinfecting medical devices. This storage device can rotate 360° through a bearing sleeve. Fixed columns are provided on four walls of the square column except for the left and right side walls. There are U-shaped clips made of rubber material on the fixed columns to fix medical devices. Since medical devices can be fixed and stored on four sides, the number of stored devices is increased, and the internal space of this storage device is fully utilized.

[0004] However, when the existing storage cabinet with a sterilization function is used to clean and disinfect medical scissors and clip instruments, it is easily blocked by the structure of the medical devices themselves, resulting in relatively large cleaning dead corners. In view of this, a storage cabinet with a sterilization structure is proposed to solve the above problems. Summary of the Invention

[0005] Aiming at the deficiencies existing in the prior art, the present invention proposes a storage cabinet with a sterilization structure to solve the technical problem that when the existing storage cabinet with a sterilization function is used to clean and disinfect medical scissors and clip instruments, it is easily blocked by the structure of the medical devices themselves, resulting in relatively large cleaning dead corners as mentioned in the above background art.

[0016] Furthermore, a dryer is arranged on the side wall of the cabinet, and multiple groups of disinfection lamps are arranged inside the cabinet.

[0017] Furthermore, mounting shafts are arranged at both ends of the mounting plate. The two mounting shafts on each mounting plate are not coaxial. Multiple groups of connecting seats are arranged at intervals on the chain of the chain conveying mechanism, and the mounting shafts are rotatably arranged inside the connecting seats.

[0018] Furthermore, a mounting cylinder is arranged on one side of the mounting plate. Multiple groups of sliding grooves are arranged at intervals on the mounting cylinder. A mounting rod is slidably arranged inside the mounting cylinder. One of each pair of the hooks is fixedly connected to the mounting cylinder, and the other hook is slidably clamped inside the sliding groove and fixedly connected to the mounting rod. The driving mechanism is connected to the mounting rod to drive the mounting rod to reciprocate inside the mounting cylinder when the mounting plate moves below the cleaning assembly.

[0019] Furthermore, the driving mechanism includes:

[0020] A mounting disc is provided with a guiding column on one side. The guiding column is slidably arranged along its axis inside the cabinet. An arc-shaped track is arranged on the other side of the mounting disc. A guiding block is arranged at the end of the mounting rod, and the guiding block is slidably clamped inside the arc-shaped track;

[0021] A linkage assembly is arranged inside the cabinet and connected to the output shaft of the motor and the mounting disc, so as to convert the rotation of the output shaft of the motor into driving the mounting disc to reciprocate; and

[0022] A guiding frame is fixedly arranged inside the cabinet. The bottom of the guiding frame is aligned with one end opening of the arc-shaped track, and the opening at the top is in a flared shape.

[0023] Furthermore, the linkage assembly includes:

[0024] The first universal joint is arranged on one side of the mounting plate;

[0025] The driving gear is arranged on the output shaft of the motor;

Detailed implementation manners

[0043] The present invention will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present invention and cannot be understood as limiting the protection scope of the present invention. Those skilled in the art can make some non - essential improvements and adjustments to the present invention according to the above application content.

[0044] Example:

[0045] As Figures 1 to 3As shown in the figure, the present invention provides a storage cabinet with a sterilization structure, which includes a cabinet body 1. An access window 2 and a placement window 3 are opened on the cabinet body 1. It also includes two sets of chain conveying mechanisms arranged in a staggered manner and multiple sets of mounting plates 12 arranged in parallel. A motor 10 for driving the sprocket 9 in the chain conveying mechanism to rotate is provided on the cabinet body 1. Mounting shafts 13 are provided at both ends of the mounting plate 12. The two mounting shafts 13 on each set of mounting plates 12 are not coaxial. Multiple connecting seats 11 are arranged at intervals on the chain of the chain conveying mechanism. The mounting shaft 13 is rotatably arranged in the connecting seat 11. On one side of the mounting plate 12, multiple pairs of mounted hooks 17 are provided.

[0046] When the storage cabinet is in use, the finger rings of the scissor clamp instruments are hung on a pair of hooks 17 through the placement window 3. The two motors 10 are respectively used to control the rotation of the sprockets 9 in the two sets of chain conveying mechanisms to drive the chains to run. Since the two sets of chain conveying mechanisms are arranged in a staggered manner, each set of mounting plates 12 can always remain parallel during the movement process to stably convey the instruments. After the instruments move a certain distance along the extension direction of the chain inside the cabinet body 1 and move from the inside of the cabinet body 1 to one side of the access window 2, the instruments can be taken out and used through the access window 2.

[0047] As Figures 1 to 2 shown in the figure, in this embodiment, a cleaning component is provided inside the cabinet body 1. The instruments on the hooks 17 are rinsed through the cleaning component. The cleaning component includes a cleaning pipe 5 arranged inside the two sets of chain conveying mechanisms. Nozzles are provided at the bottom of the cleaning pipe 5. A water pump 6 is fixedly provided on the cabinet body 1. One end of the water pump 6 is externally connected to a water source, and the other end is communicated with the cleaning pipe 5. A water storage tank 4 is also provided at the bottom of the cabinet body 1.

[0048] When the instruments are conveyed to the lower part of the cleaning pipe 5 through the chain conveying mechanism, the water pump 6 can extract the externally connected water source or disinfectant liquid and spray it out under pressure through the nozzles to clean the instruments. The cleaned water enters the water storage tank 4 for convenient discharge. A dryer 8 is also provided on the side wall of the cabinet body 1, and multiple disinfection lamps 7 are provided inside the cabinet body 1. The cleaned instruments can be moved to one side of the dryer 8 for drying. After drying is completed, they can be moved to the top of the cabinet body 1 and disinfected by the disinfection lamps 7.

[0049] As Figure 3 and Figure 7 shown in the figure, in this embodiment, a mounting cylinder 14 is provided on one side of the mounting plate 12. Multiple sliding grooves 15 are opened at intervals on the mounting cylinder 14. A mounting rod 16 is slidably inserted into the mounting cylinder 14. One of each pair of hooks 17 is fixedly connected to the mounting cylinder 14, and the other hook 17 is slidably clamped in the sliding groove 15 and fixedly connected to the mounting rod 16.

[0050] By controlling the sliding of the mounting rod 16 within the mounting cylinder 14, during the sliding process of the mounting rod 16, it can drive multiple sets of hooks 17 fixedly installed above it to slide within the sliding groove 15, so as to open and close each pair of hooks 17. During the opening and closing process of the hooks 17, the scissor clip instrument can be controlled to open and close, avoiding the interior of the scissor clip instrument from not being rinsed.

[0051] As Figures 3 to 7 shown, in this embodiment, a driving mechanism connected to the output shaft of the motor 10 is provided within the cabinet body 1. When the mounting plate 12 moves below the cleaning assembly through the driving mechanism, the rotation of the output shaft of the motor 10 is converted into driving each pair of hooks 17 to open and close. The driving mechanism is connected to the mounting rod 16 to drive the mounting rod 16 to reciprocally slide within the mounting cylinder 14 when the mounting plate 12 moves below the cleaning assembly. The driving mechanism includes a mounting disk 23. One side of the mounting disk 23 is provided with a guiding column 27. The guiding column 27 is slidably arranged along its axis within the cabinet body 1. The other side of the mounting disk 23 is provided with an arc-shaped track 24. The end of the mounting rod 16 is provided with a guiding block 20. The guiding block 20 can be slidably clamped within the arc-shaped track 24. A linkage assembly connected to the output shaft of the motor 10 and the mounting disk 23 is provided within the cabinet body 1. Through the linkage assembly, the rotation of the output shaft of the motor 10 is converted into driving the mounting disk 23 to reciprocally slide. The linkage assembly includes a first universal joint 28 arranged on one side of the mounting disk 23. A driving gear 29 is arranged on the output shaft of the motor 10. A driven gear 30 is rotatably arranged within the cabinet body 1. The driven gear 30 meshes with the driving gear 29. The number of teeth of the driving gear 29 is greater than the number of teeth of the driven gear 30. A second universal joint 31 is eccentrically arranged on one side of the driven gear 30. The second universal joint 31 is connected to the first universal joint 28 through a connecting rod 32.

[0052] The mounting rod 16 performs circumferential translation under the action of two sets of chain conveying mechanisms until the guiding block 20 at one end of the mounting rod 16 enters the arc-shaped track 24. And while the motor 10 drives the chain conveying mechanism to move, it drives the driving gear 29 to rotate, so that the driven gear 30 rotates at an accelerated speed. During the movement process of the driven gear 30, the mounting rod 16 can reciprocally move within the mounting cylinder 14 through the arrangement of the second universal joint 31, the first universal joint 28, and the connecting rod 32, so as to achieve the purpose of controlling the opening and closing of the instrument when the instrument moves below the cleaning assembly. And a limiting nut 18 is arranged at one end of the mounting rod 16. An elastic member 19 is arranged between the limiting nut 18 and the mounting cylinder 14. During the sliding process of the mounting rod 16, the elastic member 19 is compressed. When the mounting rod 16 is not subjected to external force, it can be reset under the action of the elastic member 19, causing the guiding block 20 to be reset, which is convenient for entering the arc-shaped track 24 next time.

[0053] As Figures 4 to 6As shown, in this embodiment, the driving mechanism further includes a guiding frame 22 fixedly arranged in the cabinet body 1. The bottom of the guiding frame 22 is aligned with the opening at one end of the arc-shaped track 24, and the opening at the top is flared. A baffle 25 is arranged at one end of the arc-shaped track 24 close to the guiding frame 22. The inner side of the baffle 25 is hinged to the inner side of the arc-shaped track 24, and a torsion spring (not shown in the figure) is arranged at the hinge point. The outer side of the baffle 25 abuts against the end face of the arc-shaped track 24.

[0054] The guiding block 20 is guided through the arrangement of the guiding frame 22, so that the guiding block 20 can more easily enter the arc-shaped track 24. And when the guiding block 20 moves to the bottom end of the guiding frame 22 and has not entered the arc-shaped track 24, since the arc-shaped track 24 is in a moving state, when the arc-shaped track 24 moves to abut against a part of the guiding block 20 protruding from the bottom end of the guiding frame 22, the baffle 25 is pushed to flip and the torsion spring is compressed, avoiding the impact between the arc-shaped track 24 and the guiding block 20, and controlling the baffle 25 to reset under the action of the torsion spring after the guiding block 20 enters the arc-shaped track 24, ensuring that the guiding block 20 can smoothly enter the arc-shaped track 24 and improving the reliability of the internal structure of the storage cabinet.

[0055] As Figures 5 to 7 shown, in this embodiment, the mounting cylinder 14 is rotatably arranged at one end of the mounting plate 12 along its axis. A driving gear 21 is arranged at the end of the mounting rod 16. Multiple groups of driving racks 26 are arranged in a staggered manner on both sides of the inner wall of the arc-shaped track 24. The driving racks 26 are meshed with the driving gear 21. After the guiding block 20 enters the arc-shaped track 24, the driving gear 21 can alternately mesh with the driving racks 26 on both sides of the inner wall of the arc-shaped track 24 to drive the mounting cylinder 14 to swing reciprocally at the end of the mounting plate 12, thereby driving the instrument to swing, increasing the contact surface between the instrument and the cleaning liquid, and making the cleaning more thorough.

[0056] The specific usage mode and beneficial effects of the present invention:

[0057] The storage cabinet can be used for disinfecting and storing medical scissor clamp instruments. The two groups of finger rings of the medical scissor clamp instruments are respectively hung on a pair of hooks 17. The instruments that have been cleaned and disinfected in the cabinet body 1 can be taken through the access window 2, and the used instruments can be put into the cabinet body 1 through the placement window 3. After the instruments to be cleaned are put into the cabinet body 1, the motor 10 is controlled to start to drive the two groups of chain conveying mechanisms to move. Since the two groups of chain conveying mechanisms are arranged in a staggered manner, the mounting plate 12 can be driven to translate circumferentially in the cabinet body 1, so as to drive the instruments to enter below the cleaning assembly, and the cleaned instruments can be moved to the access window 2 for use. When the instruments enter below the cleaning assembly, the rotation of the output shaft of the motor 10 can be converted into driving each pair of hooks 17 to open and close through the driving mechanism, so that the scissor clamp instruments are continuously opened and closed during the cleaning process, thereby cleaning the dead corners inside the scissor clamp instruments and improving the cleaning and disinfection effect. It can also be used for storing instruments with hanging rings or ropes. The engagement of the driving rack 26 and the driving gear 21 can drive the instruments to swing during the cleaning process, so as to increase the contact surface between the instruments and the liquid. At the same time, the cleaning area is separated from the drying and disinfection storage area without interference with each other, improving the practicability of the storage cabinet.

[0058] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments. Based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
