Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an endoscope cleaning and disinfecting machine with an anti-pressure function. Background Art

[0002] The contents in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] An endoscope cleaning and disinfecting machine is a medical device used to clean and disinfect endoscopes. It usually consists of a cleaning and disinfecting tank provided on the machine body and a hatch for sealing the cleaning and disinfecting tank.

[0004] In related technologies, the door of an endoscope cleaning and disinfecting machine is usually hingedly connected to the machine body. On this basis, a driving device (such as an electric push rod) is used to drive the door to rotate relative to the machine body, so that the door can be automatically opened or closed.

[0005] The door of an existing endoscope cleaning and disinfecting machine usually only has an open position and a closed position, wherein the process of the door moving from the open position to the closed position is roughly as follows: the output shaft of the driving component extends to drive the door to rotate relative to the machine body, so that the door gradually approaches the machine body until the door just contacts the machine body and completely covers the cleaning and disinfection tank. Thereafter, the force of the driving component driving the door to rotate will be converted into an extrusion force applied by the door to the machine body. Under the action of this extrusion force, the gap between the door and the machine body is further reduced. Only then is the door in the closed position, thereby ensuring that the cleaning and disinfection tank can be reliably sealed by the door when the door is in the closed position.

[0006] However, in actual operation, there is no time interval between the door's movement from the position completely blocking the cleaning and disinfection tank to the closed position, so that when there is foreign matter between the door and the machine body (such as the endoscope tube or the hand of the relevant operator), the relevant operator does not have enough reaction time to deal with the foreign matter, so that the door may directly squeeze the foreign matter. In this case, it may cause the endoscope cleaning and disinfection machine to malfunction or even cause unnecessary safety accidents. Summary of the Invention

[0007] The object of the present invention is to provide an endoscope cleaning and disinfecting machine with an anti-pressure function. By improving the driving component used to drive the rotation of the cabin door, when the cabin door moves from the open position to the blocking position, the time required for the cabin door to move from the blocking position to the closed position can be effectively extended, thereby giving relevant operators more time to discover foreign objects that may exist between the cabin door and the body, thereby effectively improving the safety and reliability of the cabin door during the closing process.

DETAILED DESCRIPTION

[0045] Please refer to Figures 1 to 9 This embodiment provides an endoscope cleaning and disinfecting machine with an anti-pressure function, so as to at least overcome the technical problem discovered by the inventors of this application that during the closing process of the hatch 20 of the existing endoscope cleaning and disinfecting machine, there is no time interval when the hatch 20 moves from the position of completely blocking the cleaning and disinfection tank 11 to the closed position, so that when foreign matter is between the hatch 20 and the machine body 10, the relevant operator has no sufficient reaction time to deal with the foreign matter.

[0046] Specifically, combined Figure 1 As shown, the endoscope washer-disinfector comprises a body 10 and a freely openable and closable door 20. The body 10 is provided with a cleaning and disinfection tank 11 for storing endoscopes and other related medical devices and performing cleaning and disinfection on these medical devices. The door 20 is hingedly connected to the body 10 and can seal the cleaning and disinfection tank 11, thereby making the cleaning and disinfection tank 11 a relatively closed chamber during cleaning and disinfection operations.

[0047] It is understandable that, in actual implementation, the number of cleaning and disinfection tanks 11 provided on the body 10 can be set as needed. At the same time, as for the number of doors 20, the cleaning and disinfection tank 11 can be sealed by one door 20. Of course, one door 20 can also be used to seal multiple cleaning and disinfection tanks 11 at the same time. This is not limited here. For example, Figure 1 and Figure 2 The figure shows a double-chamber endoscope washer-disinfector with two cleaning and disinfecting tanks 11 provided on a machine body 10 , and each cleaning and disinfecting tank 11 is equipped with an independent cabin door 20 .

[0048] In addition, as for the connection between the door 20 and the body 10, Figure 3 and Figure 6As shown, the door 20 can be hingedly connected to the body 10 by means of a hinge 30, thereby enabling the door 20 to open or close the cleaning and disinfection tank 11 by rotating relative to the body 10. Specifically, the door 20 is hingedly connected to the body 10 by a hinge shaft 31 in the hinge 30. Furthermore, the door 20 has a sealing portion 21 for sealing the cleaning and disinfection tank 11 and a protruding portion 22 protruding from one side of the cleaning and disinfection tank 11, with the hinge position of the door 20 and the body 10 as the boundary. When the door 20 is closed, Figure 8 As shown, the cleaning and disinfection tank 11 can be reliably sealed by the sealing portion 21 .

[0049] Furthermore, the door 20 has an open position, a blocking position and a closed position, wherein Figure 6 As shown, when the door 20 is in the open position, the door 20 is in a tilted state, at this time, the cleaning and disinfection tank 11 is in the open state; Figure 8 As shown, when the hatch 20 is in the closed position, the hatch 20 is in a horizontal state. At this time, the cleaning and disinfection tank 11 is in a sealed state, and the hatch 20 will apply a sufficiently large squeezing force to the body 10 to ensure that the cleaning and disinfection tank 11 is reliably sealed by the hatch 20; Figure 7 As shown, the shielding position of the door 20 refers to the position where the door 20 just contacts the body 10 to completely shield the cleaning and disinfection tank 11 .

[0050] At the same time, the center of gravity of the hatch 20 can be set at the sealing part 21, so that when the hatch 20 is in the open position, the hatch 20 has a tendency to move toward the side of the cleaning and disinfection tank 11, and the hatch 20 can be made of a lighter material such as ABS plastic or tempered glass.

[0051] At this time, if Figure 1 or Figure 6 As shown, a supporting step 12 can be provided on the body 10 located at the periphery of the cleaning and disinfection tank 11, that is, the supporting step 12 is arranged around the cleaning and disinfection tank 11, and when the cabin door 20 is in the blocking position or the closed position, the sealing portion 21 of the cabin door 20 can be supported on the supporting step 12, so that the cabin door 20 is supported by the supporting step 12, and a sealing strip 13 can also be provided on the supporting step 12, so that when the cabin door 20 is in the closed position, the extrusion force applied by the sealing portion 21 of the cabin door 20 to the body 10 can squeeze the sealing strip 13, thereby further ensuring that the cleaning and disinfection tank 11 can be reliably sealed by the cabin door 20 when the cabin door 20 is in the closed position.

[0052] On this basis, if Figure 2 As shown, the endoscope cleaning and disinfecting machine provided in this embodiment further includes a driving component 40 for driving the cabin door 20 to rotate relative to the machine body 10, thereby opening or closing the cleaning and disinfecting tank 11.

[0053] Specifically, the driving component 40 includes a driving member 41 and a position holding member 42, wherein Figure 3 or Figure 6 As shown, the position retaining member 42 is connected to the cabin door 20. Specifically, the position retaining member 42 is connected to the bottom of the protrusion 22. The driving member 41 can use the position retaining member 42 to move the cabin door 20 from the open position to the blocking position and the closed position in sequence. Moreover, when the cabin door 20 moves from the open position to the blocking position, the position retaining member 42 can extend the time required for the cabin door 20 to move from the blocking position to the closed position.

[0054] That is to say, during the process of closing the cabin door 20, the cabin door 20 will first move from the open position to the blocking position. When the cabin door 20 is in the blocking position, the cabin door 20 is just in contact with the body 10 to completely block the cleaning and disinfection tank 11. At this time, the extrusion force applied by the cabin door 20 to the body 10 is only part of the gravity of the cabin door 20. Therefore, even if there is foreign matter between the cabin door 20 and the body 10, the cabin door 20 is not enough to crush the foreign matter. On this basis, by extending the time required for the cabin door 20 to move from the blocking position to the closed position by the position retaining member 42, the relevant operating personnel can have more reaction time to discover foreign matter that may exist between the cabin door 20 and the body 10, and promptly control the driving member 41 to stop the action when foreign matter is found, thereby avoiding the cabin door 20 from continuing to close and crushing the foreign matter, thereby improving the safety and reliability of the entire cabin door 20 closing process.

[0055] It should be noted that the method of extending the time required for the door 20 to move from the blocking position to the closed position to improve the safety of the door 20 during closing is more effective when the foreign object between the door 20 and the body 10 is the operator's hand. The reason is that once the door 20 moves from the open position to the blocking position, the door 20 will gently press on the hand of the relevant operator. At this time, the relevant operator can feel his hand being pressed at the first time, so that he can control the driving member 41 to stop moving in time to avoid the relevant operator's hand from being crushed, thereby avoiding unnecessary safety accidents.

[0056] It is understandable that in order to extend the time required for the door 20 to move from the blocking position to the closed position by utilizing the position retaining member 42, this embodiment provides a driving member 41 and a position retaining member 42 with a relatively simple structure to achieve the above function.

[0057] Specifically, if Figure 5 As shown, the position retaining member 42 disposed at the bottom of the protruding portion 22 is provided with a moving groove 421 , and the moving groove 421 has a first end 421 a close to the protruding portion 22 and a second end 421 b away from the protruding portion 22 .

[0058] At this time, if Figure 4 As shown, the driving member 41 includes a movable shaft 411 and a driving part 412, wherein the movable shaft 411 is movably arranged in the movable groove 421, that is, the movable shaft 411 can move freely between the first end 421a and the second end 421b of the movable groove 421, and the axis of the movable shaft 411 is parallel to the axis of the hinge shaft 31.

[0059] The driving portion 412 is used to drive the moving shaft 411 to move in the moving groove 421. Figure 3 or Figure 6 As shown, the driving portion 412 can be but is not limited to a linear drive hingedly connected to the body 10. Furthermore, the linear drive can be a conventional driving device such as an electric push rod, a cylinder or a hydraulic cylinder. In this case, the output shaft of the linear drive is hingedly connected to the movable shaft 411.

[0060] Based on the above settings, Figure 6 As shown, when the hatch 20 is in the open position, the output shaft of the linear drive serving as the driving portion 412 is in a retracted state, and the movable shaft 411 is located at the second end 421b of the movable slot 421. At this time, when the linear drive does not drive the movable shaft 411, the output shaft of the linear drive together with the movable shaft 411 will apply a pulling force to the position retaining member 42, thereby ensuring that the hatch 20 is always in the open position.

[0061] When the hatch 20 needs to be closed, the output shaft of the linear actuator slowly extends. At this time, since the center of gravity of the hatch 20 is located at the sealing portion 21, the hatch 20 will slowly rotate toward the direction of the cleaning and disinfection tank 11 under the action of its own gravity until the hatch 20 moves from the open position to the blocking position. In the process of the hatch 20 moving from the open position to the blocking position, since the output shaft of the linear actuator is slowly extended, and the hatch 20 will drive the position retaining member 42 to move synchronously, the moving shaft 411 is always located at the second end 421b of the moving groove 421 under the limiting action of the position retaining member 42. That is to say, Figure 7 As shown, when the door 20 is in the shielding position, the movable shaft 411 is also located at the second end 421 b of the movable slot 421 . At this time, the squeezing force applied by the door 20 to the body 10 is only a part of the gravity of the door 20 .

[0062] Thereafter, as the output shaft of the linear actuator continues to extend, the hatch 20 and the position retaining member 42 will remain stationary. At this time, the movable shaft 411 can be driven by the linear actuator to move from the second end 421b of the movable slot 421 to the first end 421a. During this process, the linear actuator does not apply a thrust to the hatch 20 through the movable shaft 411 and the position retaining member 42. Figure 8As shown, after the movable shaft 411 moves to the first end 421a of the movable groove 421 under the drive of the linear driver, if the linear driver continues to drive the movable shaft 411 to move, the linear driver will apply a thrust to the cabin door 20 through the movable shaft 411 and the position retaining member 42. The thrust is eventually converted into an extrusion force applied by the cabin door 20 to the body 10. At this time, the gap between the cabin door 20 and the load-bearing step 12 of the body 10 is further reduced, and the cabin door 20 will squeeze the sealing strip 13 on the load-bearing step 12, thereby achieving reliable sealing of the cleaning and disinfection tank 11.

[0063] It can be seen from this that, during the movement of the door 20 from the blocking position to the closed position, the linear actuator must first drive the movable shaft 411 from the second end 421b of the movable slot 421 to the first end 421a before the linear actuator can apply a thrust to the door 20 via the movable shaft 411 and the position retaining member 42. This effectively prolongs the time required for the door 20 to move from the blocking position to the closed position, thereby providing operators with more reaction time to detect any foreign objects that may be between the door 20 and the body 10, thereby minimizing the possibility of the foreign objects being crushed by the door 20. Furthermore, in actual implementation, the time that the position retaining member 42 can extend can be adjusted as needed simply by changing the length of the movable slot 421.

[0064] It is understandable that in order to improve the stability of the door 20 when it moves from the open position to the shielding position, in actual implementation, Figure 2 As shown, each door 20 may be equipped with two driving components 40 , and the two driving components 40 are disposed opposite to each other along the width direction of the protruding portion 22 of the door 20 .

[0065] At the same time, in order to improve the stability of the driving portion 412 of the driving member 41 in the single driving component 40 when driving the moving shaft 411 to move in the moving groove 421, as shown in FIG. Figure 4 and Figure 5 As shown, the number of position retaining members 42 of each driving component 40 can be set to two, and the two position retaining members 42 are relatively positioned. Furthermore, the two position retaining members 42 can be an integrated structure, and the movable groove 421 provided on the position retaining member 42 is a hole that passes through the opposite sides of the position retaining member 42 and is in the shape of a long waist. At this time, the two ends of the movable shaft 411 respectively pass through the movable grooves 421 of the two position retaining members 42, and the two ends of the movable shaft 411 are provided with limiting members 413 for maintaining the movable shaft 411 in the movable grooves 421 of the two position retaining members 42. The limiting member 413 can be but is not limited to an open retaining ring, and the output shaft of the linear driver serving as the driving part 412 is hingedly connected to the part of the movable shaft 411 located between the two position retaining members 42.

[0066] Further, continue to refer to Figure 4A sliding sleeve 414 can be respectively provided on the outer walls at both ends of the movable shaft 411, and the sliding sleeves 414 at both ends of the movable shaft 411 are respectively slidably matched with the movable groove 421 of the corresponding position retaining member 42, so that when the linear drive drives the movable shaft 411 to move from the second end 421b of the movable groove 421 to the first end 421a, the friction between the movable shaft 411 and the movable groove 421 is reduced, so that the movable shaft 411 can move more smoothly in the movable groove 421, thereby further avoiding the movable shaft 411 from applying thrust to the position retaining member 42 and the cabin door 20 when moving in the movable groove 421.

[0067] On the other hand, although this embodiment can extend the time required for the door 20 to move from the blocking position to the closed position by providing the position retaining member 42, in practice there may be a situation where the relevant operator does not find foreign objects between the door 20 and the body 10 during this extended period of time.

[0068] To this end, the endoscope cleaning and disinfecting machine provided in this embodiment further includes a detection unit 50 and a control unit 60, wherein the detection unit 50 is provided on the body 10 and is used to detect whether the door 20 is in the blocking position. In actual implementation, Figure 6 As shown, the detection part 50 can be but is not limited to a proximity switch set on the supporting step 12. Furthermore, the proximity switch can be set on the side of the supporting step 12 close to the hinge position of the cabin door 20 and the body 10 to improve the accuracy of the proximity switch in detecting the position of the cabin door 20.

[0069] At this time, if Figure 9 As shown, the detection part 50 and the driving part 41 are both communicatively connected with the control part 60. Specifically, the communication connection between the driving part 41 and the control part 60 refers to the communication connection between the linear driver serving as the driving part 412 in the driving part 41 and the control part 60. The control part 60 can be, but is not limited to, a controller with a timing function, through which the position information sent by the detection part 50 can be received, and the action of the linear driver can be controlled.

[0070] In addition, the control unit 60 also presets a time threshold for the cabin door 20 to move from the open position to the blocking position, and the control unit 60 can record the time after the cabin door 20 starts to move from the open position. That is, once the cabin door 20 starts to move from the open position, the control unit 60 will start synchronous timing.

[0071] With such an arrangement, in actual use, once the cabin door 20 starts to move, the control unit 60 starts to synchronize timing. When the time recorded by the control unit 60 after the cabin door 20 starts to move from the open position reaches the time threshold, and the detection unit 50 does not detect that the cabin door 20 is in the blocking position (that is, the control unit 60 does not receive the position information sent by the detection unit 50), it means that there may be foreign matter between the cabin door 20 and the body 10. At this time, the control unit 60 promptly controls the driving member 41 to stop moving, that is, the output shaft of the linear drive no longer extends, thereby preventing the cabin door 20 from crushing possible foreign matter.

[0072] It should be noted that, continue to refer to Figure 9 In actual implementation, a corresponding alarm unit 70, such as an alarm, can be set up, and the alarm unit 70 can be communicated with the control unit 60. When the control unit 60 does not receive the location information sent by the detection unit 50 within a predetermined time threshold, the control unit 60 can control the alarm unit 70 to issue an early warning signal in time to remind relevant operators to handle it.

[0073] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
