Description

Technical Field

[0001] This invention relates to the field of sterilization technology, specifically to a sterilization device for sterile areas in operating rooms. Background Technology

[0002] However, most common sterilization devices for sterile areas are fixed structures or have limited adjustment ranges. Their height adjustment usually relies on simple electric push rods or screw rods, which have problems such as not being able to accurately lock at any position within the stroke range, or being bulky and inconvenient to adjust flexibly. At the same time, their sterilization range is often fixed and cannot be flexibly adapted to the dynamic changes in the placement of instruments or the activity area of ​​medical staff during surgery. This results in an excessively large sterilization range causing energy waste, or an excessively small range leaving sterilization dead zones. Common sterilization devices for sterile areas are inconvenient to adjust the sterilization range during use, and the height adjustment method lacks novelty. They are also inconvenient to adjust the height position of the sterilization equipment and cannot flexibly adapt to sterilization objects of different heights. Therefore, we propose a sterilization device for sterile areas in operating rooms. Summary of the Invention

[0003] The purpose of this invention is to provide a sterilization device for sterile areas in operating rooms.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a sterilization device for a sterile area in an operating room, comprising a sterilization device, a telescopic frame for adjusting the sterilization height installed at the upper end of the sterilization device, a sterilization rack for mounting sterilization equipment installed on the telescopic frame, a fixed slide rail installed on the telescopic frame, and staged range slide rails for defining the sterilization area installed on the left and right sides of the fixed slide rail, a lifting block for adjusting the telescopic frame's extension degree installed inside the sterilization device, and two lifting frames for providing power for lifting the lifting blocks installed on one side of the sterilization device.

[0005] As a further embodiment of the present invention: the fixed slide rail is installed with a top frame and a bottom frame in sequence from top to bottom on the side near the sterilization device, the upper end of the bottom frame is equipped with a movable frame, and a threaded rod is rotatably connected to the bottom frame.

[0006] As a further aspect of the present invention: the threaded rod and the movable frame are connected by a helical connection, and the rear end of the stepped range slide rail is connected to a connecting plate for connecting the stepped range slide rail and the fixed slide rail, and the connecting plate is located between the movable frame and the top frame.

[0007] As a further embodiment of the present invention: the upper end of the top frame is provided with a positioning hole, and the upper end of the connecting plate is equipped with a positioning post for cooperating with the positioning hole. The sterilization rack is fixedly installed with a motor, and the output end of the motor is equipped with a rolling wheel. The outer wall of the rolling wheel is in close contact with the outer wall of the fixed slide rail.

[0008] As a further aspect of the present invention: a lifting groove is provided on one side of the two lifting frames that are close to each other, and a lifting shaft is slidably connected inside the lifting groove, and the outer wall of the lifting shaft is rotatably connected to the lifting block.

[0009] As a further aspect of the present invention: the sterilization device has a lifting slide groove inside, and the inner wall of the lifting slide groove is slidably connected to the outer wall of the telescopic frame. The lower end of the telescopic frame is equipped with a lifting block that is slidably connected to the inner wall of the lifting slide groove, and the lifting block is connected to the lifting block.

[0010] As a further aspect of the present invention: two mounting plates are installed at the rear end of the sterilization device, and a lifting control shaft is rotatably connected between the two mounting plates. The outer wall of the lifting control shaft is rotatably connected to two lifting frames.

[0011] As a further aspect of the present invention: a rotating rod is rotatably connected to the side end of the sterilization device, a position fixing frame is installed on the outer wall of the rotating rod, and a rotating fixing shaft is installed on the side of the position fixing frame near the sterilization device. A rotating fixing hole is opened on the side end of the sterilization device to fix the rotating state of the rotating rod in cooperation with the rotating fixing shaft.

[0012] As a further aspect of the present invention: the two lifting frames are provided with snap-fit ​​holes on the sides that are far apart from each other, and the position fixing frame is fixedly connected with snap-fit ​​posts for cooperating with the snap-fit ​​holes.

[0013] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows: 1. This invention uses a telescopic frame, lifting block, and lifting structure to form a height adjustment system. The telescopic frame directly achieves basic adjustment of the sterilization height, while the lifting block and lifting frame work together to further precisely control the degree of extension and retraction. It can adapt to sterilization objects of different heights and can adjust the slide rail range according to the size and shape of the sterilization object, avoiding energy waste due to an excessively large sterilization area or incomplete sterilization due to an excessively small area. It is especially suitable for scenarios where precise sterilization of local areas is required, improving the accuracy and resource utilization of the overall sterilization operation. 2. This invention uses a base frame, movable frame, and threaded rod to form a spiral drive adjustment structure. This structure can adapt to the limited range of the slide rail according to the height range of the object to be sterilized. It can also avoid interference with the sterilization equipment or the items to be sterilized by fine-tuning the position of the slide rail in a step-by-step range, thus improving the flexibility of scene adaptation. The lifting slide groove of the lifting frame and the lifting shaft form a sliding + rotation dual cooperation, which ensures the smooth adjustment of the lifting block to the telescopic frame, while reducing component wear and extending the service life of the lifting structure. 3. This invention uses a lifting control shaft between two mounting plates to rotatably connect to the lifting frame, allowing the lifting frame to flexibly adjust its angle around the lifting control shaft. Based on the position of the lifting block and the telescopic requirements of the telescopic frame, the tilt angle of the lifting frame can be finely adjusted to ensure precise power transmission from the lifting frame to the lifting block. The rotation state of the rotating rod is locked by the cooperation of the rotating fixing shaft and the rotating fixing hole. The locking pin on the position fixing frame and the locking hole on the lifting frame constitute a precise positioning and fixing structure, which can directly lock the angular position of the lifting frame, ensuring the working stability of the lifting frame and reducing the risk of sterilization failure due to lifting frame displacement.

[0017] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0018] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] Example 1 This invention provides a sterilization device for sterile areas in operating rooms. When performing delicate neurosurgical procedures in an operating room, it is necessary to continuously sterilize the area around the operating table. Traditional fixed sterilization devices are difficult to adapt to dynamically changing sterilization requirements. At this point, medical staff can activate the sterilization device. The operating procedure is as follows: 1. Adjustment of sterilization range: By combining different stepped range slide rails 21 with fixed slide rails 24, a closed annular slide rail is formed. By rotating the threaded rod 31 on the base frame 3, the movable frame 33 is driven to move upward, and together with the top frame 32, the connecting plate 34 is clamped, thereby firmly installing the stepped range slide rail 21 on the side of the fixed slide rail 24, and finally forming an annular sterilization track with an adjustable diameter (e.g., 0.5 meters to 1 meter). 2. Adjustment and locking of sterilization height: First, pull the position fixing bracket 51 outward so that the snap-fit ​​post 52 on it disengages from the snap-fit ​​hole 52 of the lifting bracket 23. At the same time, the rotation fixing shaft 54 ​​on the side of the position fixing bracket 51 is also pulled out from the rotation fixing hole 55 on the side of the sterilization device 1. At this time, the rotation constraint of the lifting bracket 23 is released. Then, rotate the two lifting frames 23 downwards. Since the lifting shaft is slidably connected in the groove of the lifting frame 23, rotating the lifting frame 23 will force the lifting shaft to move along the groove and push it upwards. The lifting shaft will drive the lifting block connected to it to move upwards. The lifting block 23 will then push the lifting block 41 and the telescopic frame 11 fixed to it to slide upwards along the lifting groove, thereby raising the sterilization rack 2 with the sterilization equipment installed to the required height (e.g., 80cm). Finally, rotate the lifting frame 22 in the opposite direction to the appropriate angle, push the position fixing frame back, so that the locking pin 53 is re-locked into the locking hole 52 of the lifting frame 22 at the current angle, and at the same time rotate the fixing shaft 54 ​​into the corresponding rotating fixing hole 55 to achieve double locking and ensure the stability of the lifting frame 22 and the entire height adjustment system. Start the ultraviolet sterilization equipment on the sterilization rack 2. The motor drives the rolling wheel to move the sterilization rack 11 along the circular slide rail at a constant speed, and continuously sterilize the sterile area around the operating table and the instrument placement area in 360°. Therefore, in order to effectively solve the above problems, this application proposes a sterilization device for sterile areas in operating rooms, as shown in the attached drawings of the specification. Figure 1-7As shown, the device includes a sterilization device 1. A telescopic frame 11 for adjusting the sterilization height is installed at the upper end of the sterilization device 1. A sterilization frame 2 for installing sterilization equipment is installed on the telescopic frame 11. A fixed slide rail 24 is installed on the telescopic frame 11. A staged range slide rail 21 for defining the sterilization area is installed on the left and right sides of the fixed slide rail 24. A lifting block 23 for adjusting the telescopic degree of the telescopic frame 11 is installed inside the sterilization device 1. Two lifting frames 22 for providing power for lifting the lifting block 23 are installed on one side of the sterilization device 1. Specifically, an electric telescopic rod can be installed at the upper end of the sterilization device 1, and two drive plates can be installed at the lower end of the output end of the electric telescopic rod. A barrel-shaped handle is installed between the two lifting frames 22, and then the barrel-shaped handle is arranged between the two drive plates, with the two drive plates in a parallel state. The barrel-shaped handle can move up and down along the two drive plates.

[0020] The stepped range slide rail 21 and the fixed slide rail 24 are not all set as straight lines; they can also be set as arcs. Example 2 The top frame 32 and the bottom frame 3 are installed sequentially from top to bottom on the side of the fixed slide rail 24 near the sterilization device 1. The upper end of the bottom frame 3 is equipped with a movable frame 33, and a threaded rod 31 is rotatably connected to the bottom frame 3. The threaded rod 31 is connected to the movable frame 33 by a screw. The rear end of the stepped range slide rail 21 is connected to a connecting plate 34 for connecting the stepped range slide rail 21 to the fixed slide rail 24. The connecting plate 34 is located between the movable frame 33 and the top frame 32. The top frame 32 has a positioning hole at its upper end, and the upper end of the connecting plate 34 is equipped with a positioning post 35 for cooperating with the positioning hole. The sterilization rack 2 has a motor fixedly installed inside, and the output end of the motor is equipped with a roller. The outer wall of the roller is in close contact with the outer wall of the fixed slide rail 24. A lifting groove 4 is provided on one side of the two lifting frames 22 that are close to each other, and a lifting shaft is slidably connected inside the lifting groove 4. The outer wall of the lifting shaft is rotatably connected to the lifting block 23. Specifically, the connecting plate 34 is preferably Z-shaped or a plate-like structure with similar connecting functions, used to reliably connect the staged range slide rail 21 and the fixed slide rail 24. The positioning column 35 cooperates with the positioning hole on the top frame 32 to play a preliminary positioning and error prevention role. The connection principle between the stepped range slide rail 21 and the fixed slide rail 24 is as follows: Insert the end of the connecting plate 34 into the gap between the movable frame 33 and the top frame 32, align the positioning pin 35 with the positioning hole, rotate the threaded rod 31 to drive the movable frame 33 to move upward, and use the upper surface of the movable frame 33 and the lower surface of the top frame 32 to clamp the connecting plate 34, thereby achieving a tight connection. By selecting stepped range slide rails of different lengths, sterilization areas of different sizes can be combined.

[0021] Example 3 The sterilization device 1 has a lifting slide groove inside, and the inner wall of the lifting slide groove is slidably connected to the outer wall of the telescopic frame 11. The lower end of the telescopic frame 11 is equipped with a lifting block 41 that is slidably connected to the inner wall of the lifting slide groove, and the lifting block 41 is connected to the lifting block 23. Two mounting plates 42 are installed at the rear end of the sterilization device 1, and a lifting control shaft is rotatably connected between the two mounting plates 42. The outer wall of the lifting control shaft is rotatably connected to the two lifting frames 22. A rotating rod 5 is rotatably connected to the side end of the sterilization device 1. A position fixing frame 51 is installed on the outer wall of the rotating rod 5, and a rotating fixing shaft 54 ​​is installed on the side of the position fixing frame 51 close to the sterilization device 1. A rotating fixing hole 55 is opened on the side end of the sterilization device 1 to fix the rotating state of the rotating rod 5 in cooperation with the rotating fixing shaft 54. The two lifting frames 22 have locking holes 52 on their opposite sides, and the position fixing frame 51 is fixedly connected with locking posts 53 for cooperating with the locking holes 52. Specifically, the angle between adjacent rotating fixing holes 55 can be adjusted as needed. Additionally, a rubber ring can be added to the outer wall of the snap-fit ​​post 53 to increase the friction between the snap-fit ​​post 53 and the snap-fit ​​hole 52, thereby improving the stability of the connection between the snap-fit ​​hole 52 and the snap-fit ​​post 53. Positioning of the lifting frame 22: Pull out the position fixing bracket 51. The position fixing bracket 51 will slide on the rotating rod 5, thereby driving the rotating fixing shaft 54 ​​to be pulled out from the inside of the rotating fixing hole 55. At the same time, the locking pin 53 can be moved out from the inside of the locking hole 52, thereby disconnecting the position fixing of the lifting frame 22. When the angle position adjustment of the lifting frame 22 is completed, the rotating fixing shaft 54 ​​is reinserted into the inside of the rotating fixing hole 55. At this time, the locking pin 53 can be moved back into the inside of the locking hole 52, and the position fixing bracket 51 is used to fix the position of the lifting frame 22.

[0022] The present invention provides a sterilization device for use in a sterile area of ​​an operating room, the working principle and operation procedure of which are as follows: 1. Flexible adjustment of sterile areas: Step 1: Using the connection between the stepped range slide rail 21 and the fixed slide rail 24, insert the connecting plate 34 into the upper side of the adjacent movable frame 33, and align the positioning post 35 with the positioning hole. Step 2: Rotate the threaded rod 31, which causes the movable frame 33 to move upward. Step 3: Use the clamping capacity of the movable frame 33 and the top frame 32 to fix the connecting plate 34, so that the different stage range slide rails 21 and the fixed slide rail 24 form a circular slide rail. Step 4: Start the motor and use the motor to drive the rollers to rotate, so that the sterilization rack 2 moves along the circular slide rail; Step 5: Start the sterilization equipment installed on sterilization rack 2 to sterilize the area within the circular slide rail; 2. Adjustment of the height of sterilization rack 2: Step 1: Pull the lifting frame 22 to rotate along the lifting control axis. At this time, the rotation of the lifting frame 22 will shorten the distance between the lifting frame 22 and the sterilization device 1. Step 2: The lifting block 23 is forced to move upward by shortening the distance between the sterilization device 1 and the lifting frame 22; Step 3: Use the upward movement of lifting block 23 to drive lifting block 41 to move upward, which will then push telescopic frame 11 to move upward. 3. The position of the lifting frame 22 is fixed: Step 1: Pull out the position fixing bracket 51. At this time, the position fixing bracket 51 will slide on the rotating rod 5, thereby driving the rotating fixing shaft 54 ​​to be pulled out from the inside of the rotating fixing hole 55. Step 2: Simultaneously remove the snap-fit ​​post 53 from the inside of the snap-fit ​​hole 52, thereby disconnecting the position fixation of the lifting frame 22; Step 3: When the angle position adjustment of the lifting frame 22 is completed, re-insert the rotating fixing shaft 54 ​​into the rotating fixing hole 55; Step 4: The snap-fit ​​post 53 is moved back into the snap-fit ​​hole 52, and then the position fixing bracket 51 is used to fix the position of the lifting frame 22. At this point, the entire process is completed.
