Description

Technical Field

[0001] This utility model relates to the field of medical disinfection equipment technology, and in particular to a surgical knife disinfection device. Background Technology

[0002] Sterilization of surgical instruments is a crucial step in ensuring medical safety and preventing postoperative infections. Among these methods, pressure steam sterilization is the preferred method for handling instruments resistant to high temperatures and humidity due to its reliable sterilization effect and low cost. During this process, the sterilization device must ensure that saturated steam fully contacts every surface of the instrument and maintains the required temperature and time; any "dead zones" that steam cannot reach will lead to sterilization failure. For instruments like scalpels, which have delicate structures and sharp edges, improper placement within the sterilization chamber can easily cause blade damage due to collisions or contact with the container walls. Furthermore, the close proximity of the instruments can create areas that steam cannot penetrate, posing a potential safety hazard.

[0003] In existing technologies, commonly used instrument baskets or trays are employed to hold surgical scalpels for sterilization. These baskets allow steam to pass through through their mesh structure and their partitioned design reduces instrument stacking to some extent. This approach solves the serious obstruction problem caused by haphazardly stacked instruments and avoids entanglement and collision between instruments.

[0004] However, this method has significant drawbacks: when multiple baskets are placed side by side, the blades or handles of the scalpels in each basket can easily come into contact with the common sidewall between them simultaneously. This not only results in a large area of ​​contact between the instruments and the sidewall, but more seriously, instruments from two baskets can form a face-to-face contact or extremely close proximity in this narrow central area. This area severely hinders the entry of steam and heat exchange, creating a closed dead zone that is difficult for the sterilization medium to reach, leading to incomplete sterilization. Furthermore, the existing fixed racks are inconvenient to operate when loading and unloading instruments, affecting work efficiency. Utility Model Content

[0005] Purpose of the Invention: The purpose of this invention is to provide a surgical scalpel sterilization device. The invention aims to solve the sterilization dead zone problem caused by the scalpel's surface-to-surface contact with the side walls of adjacent baskets during steam sterilization. By using an inclined grid structure and pre-reserved gaps between the frames, steam is ensured to circulate without dead zones, effectively improving sterilization reliability and operational efficiency.

[0006] Technical solution:

[0007] A surgical scalpel sterilization device includes a box body, a box door, a steam inlet, and a steam outlet, as well as several parallel frames with gaps between adjacent frames. Each frame includes multiple vertically equidistant compartments, a top fixing seat, and a bottom fixing seat. Each compartment has a front placement opening, a bottom grid, a top grid, two side grids, and a rear grid. The bottom grid and the top grid are inclined downwards towards the rear end. The bottom grid includes multiple equidistant horizontal support bars, and the end of the bottom grid near the placement opening is also provided with multiple inclined support bars extending along the length of the bottom grid. The inclined support bars and the horizontal support bars are staggered.

[0008] Furthermore, a condensate collection tank is provided at the bottom of the box, and multiple support plates are provided at the top of the condensate collection tank, forming a drainage channel between adjacent support plates; a drain outlet is provided at the bottom of the condensate collection tank.

[0009] Furthermore, the bottom surface of the bottom fixing seat is provided with a guide groove that is adapted to the position of the support plate.

[0010] Furthermore, the top and bottom of the housing are provided with multiple guide shafts extending in the front-to-back direction, and the top and bottom fixing seats are provided with guide grooves that are adapted to the guide shafts.

[0011] Furthermore, the bottom grid of the uppermost cell in an adjacent cell forms the top grid of the lower cell.

[0012] Furthermore, both the side grid and the rear grid include multiple vertical support bars arranged at equal intervals.

[0013] Furthermore, the steam inlet and steam outlet are located on both sides of the housing, with the steam inlet located at the upper end of the housing and the steam outlet located at the lower end of the housing.

[0014] Furthermore, a feeding ramp is provided at the lower front end of the box.

[0015] Beneficial effects:

[0016] 1. By designing the bottom and top grids of the receiving compartments with a unique inward and downward tilt, this structure ensures that the scalpel adheres stably to the bottom grid under gravity, thus establishing a unique and stable posture and position in the vertical direction. This design, combined with the pre-reserved gaps between the side-by-side frames, effectively isolates the scalpels in different frames in the horizontal direction. This fundamentally avoids face-to-face contact or proximity of scalpels from adjacent frames in the side wall area between them, completely eliminating any enclosed dead zones and ensuring unobstructed flow of saturated vapor around all instruments.

[0017] 2. The frame can be pushed into or pulled out of the box independently and smoothly through the cooperation of the guide shaft and guide groove. Combined with the ramp design at the front of the box, the batch loading and unloading process of scalpels is more labor-saving and faster, greatly improving the work experience and operating efficiency of medical staff.

[0023] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] like Figure 1-5 As shown, a scalpel sterilization device includes a box body 1, a box door 2, a steam inlet 3, and a steam outlet 4, as well as several parallel frames 5 with gaps between adjacent frames 5. Each frame 5 includes multiple vertically equidistant storage compartments 51, a top fixing seat 52, and a bottom fixing seat 53. Each storage compartment 51 has a front placement opening, a bottom grid 511, a top grid 512, two side grids 513, and a rear grid 514. The bottom grid 511 and the top grid 512 are inclined downwards towards the rear end. This inclined structure allows the scalpel to slide naturally backwards under gravity and stably adhere to the bottom grid, ensuring that the instrument maintains a fixed posture. The bottom grid 511 includes multiple equidistant horizontal support bars 5111. Near the placement opening, the bottom grid 511 also has multiple inclined support bars 5112 extending along the length of the bottom grid 511. The inclined support bars 5112 and the horizontal support bars 5111 are staggered to form a composite support structure, which can prevent the scalpel from sliding forward and minimize the contact area between the instrument and the support surface, ensuring that the steam fully contacts the instrument surface.

[0026] Furthermore, a condensate collection tank 6 is provided at the bottom of the housing 1, and multiple support plates 61 are provided at the top of the condensate collection tank 6, forming a drainage channel between adjacent support plates 61; a drain outlet 62 is provided at the bottom of the condensate collection tank 6 for draining the condensate generated during the sterilization process.

[0027] Furthermore, the bottom surface of the bottom fixing base 53 is provided with a guide groove 531 that corresponds to the position of the support plate 61. This guides the dripping condensate to the drain channel, preventing water accumulation from affecting the sterilization effect.

[0028] Furthermore, the top and bottom of the housing 1 are each provided with multiple guide shafts 7 extending in the front-to-back direction, and the top fixing seat 52 and the bottom fixing seat 53 are each provided with guide grooves 54 that are adapted to the guide shafts 7. This guiding mechanism ensures that the frame 5 can be smoothly pushed into and pulled out of the housing, realizing modular operation and facilitating the batch handling of scalpels.

[0029] Furthermore, the bottom grid 511 of the upper compartment 51 of the adjacent compartments 51 forms the top grid 512 of the lower compartment 51. This integrated design simplifies the structure while ensuring steam flow between the compartments.

[0030] Furthermore, both the side grid 513 and the rear grid 514 include multiple equidistant vertical support bars. This reduces contact between the scalpel and the side when the scalpel is placed flat.

[0031] Furthermore, the steam inlet 3 and the steam outlet 4 are located on both sides of the housing 1, with the steam inlet 3 located at the upper end of the housing 1 and the steam outlet 4 located at the lower end of the housing 1. This layout utilizes the principle of hot steam rising naturally and cold air sinking to form a top-down steam flow path, ensuring that saturated steam fully fills the cavity and that cold air is completely discharged from the bottom.

[0032] Furthermore, a feeding ramp 8 is provided at the lower front end of the box 1 to facilitate the workers to push the frame 5 into and out of the box 1.

[0033] The staff places the scalpels into their respective compartments 51 one by one. The inclined bottom grid 511 allows the scalpels to automatically slide to a stable position, and the staggered support bars ensure that the instruments maintain optimal posture. After filling, the frame 5 is pushed into the chamber 1 along the guide shaft 7, and the chamber door 2 is closed. After the sterilization program is started, saturated steam enters the upper part of the chamber from the steam inlet 3 and flows from top to bottom under gravity. It penetrates into each compartment through the gaps between the frames and the grid structure, fully coating the surface of each scalpel. During the steam flow, the steam pushes the cold air to the bottom and is discharged through the steam outlet 4. At the same time, condensate flows along the inclined grid into the collection tank 6 and is finally discharged from the drain outlet 62, ensuring that the chamber always maintains an ideal saturated steam environment and completing an efficient and reliable sterilization process.

[0034] The embodiments described above are merely illustrative of certain implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
