Description

Technical Field

[0001] The invention relates to the technical field of disinfection equipment, in particular to a surgical instrument disinfection equipment. Background Art

[0002] During the operation, surgical instruments will come into contact with human internal tissues and blood, and may carry various pathogens, such as bacteria, viruses, fungi, etc., so surgical instruments need to be sterilized. The reason why vertical steam sterilizers are used to sterilize surgical instruments is that steam sterilization is a very effective sterilization method. During the steam sterilization process, high-temperature and high-pressure steam can quickly kill most bacteria, viruses and fungi, thereby effectively sterilizing surgical instruments. The steam sterilizer can provide a high-temperature and high-pressure environment to ensure that the steam can fully penetrate every corner of the instrument, thereby achieving a thorough disinfection effect. The upper cover of the steam sterilizer needs to be pressed tightly during the pressing process, otherwise leakage will occur during use. However, it cannot be over-tightened, otherwise the rubber ring below will be damaged. Most steam sterilizers in the prior art cannot control the appropriate force of pressing the upper cover during use, which requires multiple debugging during the pressing of the upper cover. Multiple debugging is required to ensure that the upper cover is pressed with the appropriate force, which will increase the operating time cost of the operator and reduce work efficiency. Due to the need for multiple debugging, the use process of the steam sterilizer becomes unstable and is easily affected by the individual differences of the operators, increasing the risk of use. When the internal pressure of the steam sterilizer is too high, the rubber ring may not be completely sealed, resulting in steam or high-temperature water vapor leakage, affecting the disinfection effect, and may even cause harm to the operator.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1-Figure 8 , which is the first embodiment of the present invention, provides a surgical instrument disinfection device, which includes a disinfection component 100, a pressing component 200 and a sealing component 300, and the cooperation of the three can improve the disinfection efficiency.

[0033] The disinfection assembly 100 includes a tank body 101 , a sealing cover 102 , a fixing ring 103 and a rotating frame 104 . The sealing cover 102 is disposed above the tank body 101 , the fixing ring 103 is fixed to the top of the tank body 101 , and the rotating frame 104 is disposed above the tank body 101 .

[0034] A sealing strip is provided on the top of the fixing ring 103. When the sealing cover 102 is pressed against the top of the fixing ring 103, the tank body 101 can be sealed. At this time, the inside of the tank body 101 can be disinfected. The rotating frame 104 is provided to drive the sealing cover 102 to rotate to one side, so as to facilitate the placement of surgical instruments inside the tank body 101. This is the prior art and will not be elaborated in this solution.

[0035] The pressing assembly 200 is disposed on the sealing cover 102 , and includes a rotating member 201 and an adjusting member 202 . The rotating member 201 is located inside the sealing cover 102 , and the adjusting member 202 is disposed on one side of the rotating member 201 .

[0036] The rotating part 201 is provided to drive the sealing cover 102 to move downward, so that the sealing cover 102 and the fixing ring 103 can be pressed tightly, and when the sealing cover 102 is pressed to an appropriate force, it cannot move downward any further, so as to avoid the situation where the sealing strip is damaged due to excessive pressing of the sealing cover 102, and there is no need to manually adjust the pressing force of the sealing cover 102 multiple times, so as to improve the disinfection efficiency of surgical instruments. Through the provision of the adjusting part 202, as the sealing strip is used for a long time, its sealing effect is reduced, so it is necessary to increase the pressing force of the sealing cover 102 and the fixing ring 103, so as to ensure sufficient sealing between the two. At this time, the pressing force of the sealing cover 102 can be adjusted by the adjusting part 202, so as to increase the sealing effect of the sealing cover 102 accordingly.

[0037] The sealing assembly 300 is arranged at the bottom of the sealing cover 102, and includes a sealing member 301, an extrusion member 302, a limiting member 303 and a transmission member 304. The sealing member 301 is located at the bottom of the sealing cover 102, the extrusion member 302 is arranged on the inner side of the sealing member 301, the limiting member 303 is located on one side of the extrusion member 302, and the transmission member 304 is arranged on one side of the limiting member 303.

[0038] By setting the sealing member 301, when the internal pressure of the tank body 101 is too high, the extrusion member 302 will be pushed to move upward, so that the extrusion member 302 can drive the seal member 301 to move, so that the seal between the sealing cover 102 and the fixing ring 103 can be increased through the seal member 301, so as to avoid the leakage of the internal pressure of the tank body 101. The setting of the limiting member 303 is used to limit the extrusion member 302 to avoid excessive upward movement of the extrusion member 302, resulting in excessive extrusion force on the seal member 301, thereby causing the seal to leak. In the case where the seal 301 is damaged, through the setting of the transmission member 304, when the sealing effect of the sealing strip is reduced, the corresponding sealing effect of the seal 301 will also be reduced. When the adjusting member 202 increases the pressing force of the sealing cover 102, the limiting member 303 will be driven to move upward through the transmission member 304 at the same time, so that the distance between the limiting member 303 and the extrusion member 302 is increased, thereby increasing the moving stroke of the extrusion member 302 and increasing the extrusion force on the seal 301, thereby improving the sealing effect of the seal 301.

[0039] Example 2

[0040] Reference Figure 1-Figure 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0041] Specifically, the rotating member 201 includes a threaded column 201a, a moving block 201b and a connecting sleeve 201c. The threaded column 201a is rotatably connected to the rotating frame 104, the moving block 201b is arranged on the outside of the threaded column 201a, a through hole 102a is opened on the sealing cover 102, and the connecting sleeve 201c is fixed in the through hole 102a.

[0042] A turntable is fixed on the top of the threaded column 201a, and the threaded column 201a is connected to the rotating frame 104 through a bearing. A threaded hole is opened in the moving block 201b, and the threaded column 201a is threadedly connected to the threaded hole. A connecting ring is fixed to the bottom of the moving block 201b, and the connecting sleeve 201c is rotatably connected to the outer side of the connecting ring through a bearing, so that the connecting sleeve 201c can be connected to the moving block 201b.

[0043] When the threaded column 201a rotates, the threaded hole cooperates to drive the moving block 201b to move downward, and the moving block 201b drives the connecting sleeve 201c and the sealing cover 102 to move downward, so that the sealing cover 102 can contact with the fixing ring 103 and press the fixing ring 103 tightly.

[0044] Specifically, the rotating member 201 also includes a block 201d and a positioning sleeve 201e. A groove 201b-1 is provided on the moving block 201b. The block 201d is located in the groove 201b-1. The positioning sleeve 201e is inserted into the through hole 102a. A slot 201e-1 is provided in the positioning sleeve 201e. The block 201d slides in the slot 201e-1. A movable slot 201e-2 is provided in the positioning sleeve 201e.

[0045] There are two blocks 201d, which are located on both sides of the movable block 201b respectively. The blocks 201d are movably connected with the groove 201b-1. There are two slots 201e-1 and two movable slots 201e-2, which are located on both sides of the positioning sleeve 201e respectively. The bottom of the slot 201e-1 is connected with the movable slot 201e-2, and the two movable slots 201e-2 are not connected. The inner wall end of the movable slot 201e-2 is inclined.

[0046] When the threaded column 201a is rotating, the moving block 201b is restricted by the cooperation of the block 201d and the slot 201e-1, so as to prevent the moving block 201b from rotating synchronously with the threaded column 201a, thereby preventing the moving block 201b from being unable to move downward. When the sealing cover 102 contacts the fixing ring 103 and is pressed against the fixing ring 103 with appropriate force, the block 201d enters the movable groove 201e-2 through the slot 201e-1, and the restriction on the moving block 201b is released. When the rotation continues, the movable block 201b will lose its restriction and will rotate along with the threaded column 201a instead of moving downward, so that the sealing cover 102 can be pressed with an appropriate force, avoiding the need to adjust the sealing cover 102 multiple times, thereby reducing the working efficiency. When the block 201d continues to rotate in the movable groove 201e-2 and contacts the inclined surface of the inner wall end of the movable groove 201e-2, it will be squeezed by the inclined surface of the inner wall end of the movable groove 201e-2 and enter the groove 201b-1, so that the movable block 201b can continue to rotate.

[0047] When the sealing cover 102 needs to be opened, the threaded column 201a only needs to be rotated in the opposite direction. At this time, the block 201d will contact the side directly facing the end of the inner wall of the movable groove 201e-2, and the block 201d cannot enter the groove 201b-1. In this way, the movable block 201b can be restricted and cannot rotate with the threaded column 201a. Then, the threaded column 201a can drive the movable block 201b to move upward, so that the sealing cover 102 can be opened.

[0048] Specifically, the rotating member 201 further includes a spring 201f, and two ends of the spring 201f are respectively fixed to the inner wall of the groove 201b-1 and the block 201d.

[0049] The spring 201f applies a thrust to the block 201d, so that the block 201d and the slot 201e-1 are more tightly engaged, thereby preventing the two from being separated.

[0050] Specifically, the adjusting member 202 includes a threaded sleeve 202a, a positioning column 202b and a positioning block 202c, the threaded sleeve 202a is arranged outside the positioning sleeve 201e, the positioning column 202b is fixed to the bottom of the sealing cover 102, and the positioning block 202c is fixed to one side of the positioning sleeve 201e.

[0051] The threaded sleeve 202a is threadedly connected to the outer side of the positioning sleeve 201e. There are two positioning columns 202b and two positioning blocks 202c, which are respectively located on both sides of the positioning sleeve 201e. The positioning block 202c is movably connected to the outer side of the positioning column 202b. The two are used together to position the positioning sleeve 201e to prevent the positioning sleeve 201e from rotating. The top of the positioning column 202b is movably connected to the rotating frame 104.

[0052] With the long-term use of the sealing strip, its sealing effect is reduced. When the original clamping force of the sealing cover 102 cannot maintain sufficient sealing, if the sealing strip is directly replaced, the cost will increase, and the clamping force between the sealing cover 102 and the fixing ring 103 needs to be increased to improve the sealing of the sealing cover 102. At this time, the threaded sleeve 202a can be rotated to drive the positioning sleeve 201e to move downward. As the positioning sleeve 201e descends, the downward movement of the block 201d in the slot 201e-1 increases, and the distance entered into the movable slot 201e-2 increases, so that the movable block 201b can move downward a sufficient distance and drive the sealing cover 102 to be clamped with sufficient force, thereby compensating for the reduced sealing of the sealing strip and allowing the sealing cover 102 to provide sufficient sealing effect again.

[0053] Specifically, the sealing member 301 includes a fixing ring 301a, an extrusion ring 301b and a sealing sleeve 301c. The fixing ring 301a is fixed in the fixing ring 103, the extrusion ring 301b is located inside the fixing ring 301a, and the sealing sleeve 301c is sleeved outside the extrusion ring 301b.

[0054] There are four extrusion rings 301b, which are evenly distributed on the inner side of the fixing ring 301a in an annular shape. The extrusion ring 301b is arc-shaped as a whole, and one side is U-shaped. The sealing sleeve 301c is annular and has a certain elastic force.

[0055] When the extrusion ring 301b drives the sealing sleeve 301c to move, the sealing sleeve 301c will be stretched. When the sealing sleeve 301c contacts the fixing ring 301a and the extrusion ring 301b squeezes the sealing sleeve 301c, the three can cooperate to seal the sealing cover 102 and the fixing ring 103, thereby improving the sealing between the two and avoiding leakage inside the tank body 101.

[0056] Example 3

[0057] Reference Figure 1-Figure 8 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0058] Specifically, the sealing member 301 further includes a fixing rod 301d and a positioning frame 301e. The fixing rod 301d is fixed to one side of the extrusion ring 301b, and the positioning frame 301e is fixed to the bottom of the sealing cover 102. The fixing rod 301d is movably connected to the positioning frame 301e.

[0059] The fixing rod 301d is used to drive the extrusion ring 301b to move, so that when the extrusion ring 301b drives the sealing sleeve 301c to move, the fixing rod 301d is positioned through the positioning frame 301e to avoid the fixing rod 301d from deviating during movement.

[0060] Specifically, the extrusion member 302 includes an extrusion plate 302a and a fixing column 302b. The extrusion plate 302a is located on one side of the fixing rod 301d, and the fixing column 302b is fixed to the four corners of the top of the extrusion plate 302a.

[0061] The fixing column 302b is inserted into the sealing cover 102 and passes through the through hole 102a. The connection between the fixing column 302b and the sealing cover 102 is sealed. The extrusion plate 302a is positioned by the fixing column 302b to prevent the extrusion plate 302a from shifting when moving. The extrusion plate 302a is conical and the end of the fixing rod 301d is inclined.

[0062] When the internal pressure of the tank body 101 is too high, the air pressure inside the tank body 101 will push the extrusion plate 302a to move upward, and squeeze the end of the fixed rod 301d through the extrusion plate 302a, thereby pushing the fixed rod 301d to move, and driving the extrusion ring 301b to move through the fixed rod 301d. When the internal air pressure of the tank body 101 is exhausted, the extrusion plate 302a will fall downward by its own gravity and separate from the fixed rod 301d. At this time, the elastic force of the sealing sleeve 301c can drive the extrusion ring 301b to separate from the fixed ring 301a.

[0063] Specifically, the limiting member 303 includes a positioning ring 303a, a limiting ring 303b, a stabilizing block 303c and a stabilizing sleeve 303d. The positioning ring 303a is fixed to the top of the fixing column 302b, the limiting ring 303b is located above the positioning ring 303a, the stabilizing block 303c is fixed to one side of the connecting sleeve 201c, and the stabilizing sleeve 303d is fixed to the top of the limiting ring 303b.

[0064] There are two stabilizing blocks 303c and two stabilizing sleeves 303d, which are respectively located on both sides of the connecting sleeve 201c. The stabilizing sleeve 303d is movably connected to the stabilizing block 303c, and the limiting ring 303b is supported by the stabilizing sleeve 303d, and the positioning ring 303a is restricted by the limiting ring 303b. There is a certain distance between the limiting ring 303b and the positioning ring 303a.

[0065] When the extrusion plate 302a and the fixed column 302b move upward, the fixed column 302b will drive the positioning ring 303a to move upward. When the extrusion ring 301b applies sufficient extrusion force to the sealing sleeve 301c, the positioning ring 303a will contact the limiting ring 303b. At this time, the limiting ring 303b will restrict the positioning ring 303a, making it unable to move upward, and the extrusion plate 302a unable to move upward, so that the extrusion plate 302a can stop pushing the fixing rod 301d and the extrusion ring 301b to move, thereby avoiding the situation where the extrusion ring 301b squeezes the sealing sleeve 301c with too much force, which will cause damage to the sealing sleeve 301c.

[0066] Specifically, the transmission member 304 includes a rotating column 304a, a fixed sleeve 304b, a fixed shaft 304c and a stabilizing plate 304d. The rotating column 304a is located in the stabilizing sleeve 303d, the fixed sleeve 304b is fixed to the bottom of the positioning sleeve 201e, the fixed shaft 304c is fixed to one side of the rotating column 304a, a spiral groove 304b-1 is opened in the fixed sleeve 304b, the fixed shaft 304c slides in the spiral groove 304b-1, and the stabilizing plate 304d is fixed to one side of the connecting sleeve 201c.

[0067] The rotating column 304a is rotatably connected to the stabilizing plate 304d via a bearing, and the rotating column 304a is internally threadedly connected to the stabilizing sleeve 303d.

[0068] When the sealing effect of the sealing strip is reduced and the clamping force needs to be increased, the sealing effect of the sealing sleeve 301c will also be reduced, and the extrusion force on the sealing sleeve 301c needs to be increased. When the positioning sleeve 201e moves downward, the fixed shaft 304c will slide in the spiral groove 304b-1, and the cooperation between the two drives the rotating column 304a to rotate. When the rotating column 304a rotates, it will drive the stabilizing sleeve 303d to move upward, and drive the limiting ring 303b to move upward through the stabilizing sleeve 303d, so that the distance between the limiting ring 303b and the positioning ring 303a can be increased, and then the upward movement stroke of the extrusion plate 302a can be increased, so that the extrusion plate 302a pushes the fixed rod 301d and the extrusion ring 301b to move. Increase, and then increase the extrusion force of the extrusion ring 301b on the sealing sleeve 301c, thereby improving the sealing effect.

[0069] During use, after the surgical instrument is placed inside the tank body 101, the sealing cover 102 of the tank body 101 is rotated to the top of the tank body 101, and then the threaded column 201a is rotated to drive the moving block 201b to move downward, and the connecting sleeve 201c and the sealing cover 102 are driven downward by the moving block 201b, so that the sealing cover 102 can contact with the fixed ring 103. When the sealing cover 102 is pressed on the top of the fixed ring 103 with an appropriate force, the block 201d will enter the movable groove 201e-2 through the slot 201e-1, and the restriction on the moving block 201b will be released at this time. When the threaded column 201a continues to rotate, the moving block 201b will lose the restriction and will rotate with the threaded column 201a instead of moving downward. In this way, the sealing cover 102 can be pressed with an appropriate force, avoiding the need to adjust the sealing cover 102 multiple times, thereby reducing work efficiency.

[0070] During the sterilization process, when the internal pressure of the tank body 101 is too high, the air pressure inside the tank body 101 will push the extrusion plate 302a to move upward, and squeeze the end of the fixed rod 301d through the extrusion plate 302a, thereby pushing the fixed rod 301d to move, and the extrusion ring 301b is driven to move through the fixed rod 301d, so that the extrusion ring 301b drives the sealing sleeve 301c to contact the fixed ring 301a, and the sealing sleeve 301c is squeezed through the extrusion ring 301b. At this time, the three can cooperate to seal the sealing cover 102 and the fixed ring 103, thereby improving the sealing between the two and avoiding leakage when the internal pressure of the tank body 101 is too high.

[0071] When the extrusion plate 302a and the fixed column 302b move upward, the fixed column 302b will drive the positioning ring 303a to move upward. When the extrusion ring 301b applies sufficient extrusion force to the sealing sleeve 301c, the positioning ring 303a will contact the limiting ring 303b. At this time, the limiting ring 303b will restrict the positioning ring 303a, making it unable to move upward, and the extrusion plate 302a unable to move upward, so that the extrusion plate 302a can stop pushing the fixing rod 301d and the extrusion ring 301b to move, thereby avoiding the situation where the extrusion ring 301b squeezes the sealing sleeve 301c with too much force, which will cause damage to the sealing sleeve 301c.

[0072] With the long-term use of the sealing strip, its sealing effect is reduced. When the original clamping force of the sealing cover 102 cannot maintain sufficient sealing, if the sealing strip is directly replaced, the cost will increase, and the clamping force between the sealing cover 102 and the fixing ring 103 needs to be increased to improve the sealing of the sealing cover 102. At this time, the threaded sleeve 202a can be rotated to drive the positioning sleeve 201e to move downward. As the positioning sleeve 201e descends, the downward movement of the block 201d in the slot 201e-1 increases, and the distance entered into the movable slot 201e-2 increases, so that the movable block 201b can move downward a sufficient distance and drive the sealing cover 102 to be clamped with sufficient force, thereby compensating for the reduced sealing of the sealing strip and allowing the sealing cover 102 to provide sufficient sealing effect again.

[0073] When the sealing effect of the sealing strip is reduced and the clamping force needs to be increased, the sealing effect of the sealing sleeve 301c will also be reduced, and the extrusion force on the sealing sleeve 301c needs to be increased. When the positioning sleeve 201e moves downward, the fixed shaft 304c will slide in the spiral groove 304b-1, and the cooperation between the two drives the rotating column 304a to rotate. When the rotating column 304a rotates, it will drive the stabilizing sleeve 303d to move upward, and drive the limiting ring 303b to move upward through the stabilizing sleeve 303d, so that the distance between the limiting ring 303b and the positioning ring 303a can be increased, and then the upward movement stroke of the extrusion plate 302a can be increased, so that the extrusion plate 302a pushes the fixed rod 301d and the extrusion ring 301b to move. Increase, and then increase the extrusion force of the extrusion ring 301b on the sealing sleeve 301c, thereby improving the sealing effect.
