Description

Technical Field

[0001] This application relates to the field of medical auxiliary cleaning devices, and in particular to an instant pretreatment device for endoscopes. Background Technology

[0002] An endoscope is a medical instrument that enters the human body through various tubes to observe the internal condition of the body; some endoscopes also have therapeutic functions, such as gastroscopes, colonoscopes, and bronchoscopes; endoscopes are widely used in a variety of invasive medical examinations and treatments.

[0003] After use, endoscopes require immediate pretreatment: wipe away surface contaminants with a damp wipe or gauze containing cleaning solution, repeatedly inflate and deflate with air and water for at least 10 seconds, place the endoscope tip into a container of cleaning solution, activate the suction function, and aspirate the cleaning solution until it flows into the suction tube. Currently, the pretreatment wiping operation relies on manual labor, which is highly subjective and may leave some contaminants behind; furthermore, the long tubing makes wiping laborious and increases the difficulty of operation. Therefore, an immediate pretreatment device for endoscopes is proposed to solve the above technical problems. Summary of the Invention

[0004] One objective of this application is to provide an instantaneous pretreatment device for endoscopes.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: an immediate pretreatment device for endoscopes, comprising a movable frame, a moving device, and a clamp. The upper end of the movable frame has a placement station for placing the endoscope body. The moving device is mounted on the movable frame, and the clamp is mounted on the moving device and cooperates with the flexible tube of the endoscope body. During cleaning, the clamp is adapted to cover and confine the gauze outside the flexible tube, and the moving device is adapted to drive the clamp to move axially downward along the flexible tube.

[0006] Preferably, the moving device includes a lead screw, a slider, and a driving device. The lead screw is vertically mounted on the movable frame, the slider is vertically slidably mounted on the movable frame, the clamp is mounted on the end of the slider, and the driving device is mounted on the slider and cooperates with the lead screw. The slider is adapted to move up and down along the axial direction of the lead screw under the drive of the driving device.

[0007] Preferably, the driving device includes a motor, a threaded sleeve, and a transmission assembly. The threaded sleeve is rotatably mounted inside the slider and cooperates with the lead screw. The motor is mounted on the top of the slider and its output end is connected to the threaded sleeve through the transmission assembly. The motor is adapted to drive the threaded sleeve to rotate through the transmission assembly, thereby the threaded sleeve and the lead screw cooperate to drive the slider to move up and down.

[0008] Preferably, the end of the slider has an arc-shaped groove, and the clamp is elastically slidably installed in the arc-shaped groove. The clamp is connected to the output end of the motor through an intermittent device. When the slider moves downward, the clamp is adapted to reciprocate along the axial direction of the hose under the action of the intermittent device and the elastic force.

[0009] Preferably, the intermittent device includes an arc-shaped rack and a partial gear. The rack is mounted on the side of the clamp, and the partial gear is rotatably mounted on the slider via a rotating shaft and engages with the rack. The rotating shaft engages with the output end of the motor via a transmission assembly two. The motor is adapted to drive the partial gear to rotate via the transmission assembly two. When the toothed section of the partial gear meshes with the rack, the clamp is adapted to rotate. When the toothless section of the partial gear engages with the rack, the clamp is adapted to rotate and reset under the action of elastic force.

[0010] Preferably, the rotating shaft is connected to the transmission assembly two via a one-way bearing; when the motor rotates in the first direction, the one-way bearing is in a engaged state, and the clamp is adapted to move downward and rotate; when the motor rotates in the second direction, the one-way bearing is in a free state, and the clamp is adapted to move upward and remain stationary in the circumferential direction.

[0011] Preferably, the placement station includes a placement plate and a placement platform. The placement plate is horizontally installed on the top of the movable frame and has a placement groove at its end. The placement platform is installed on the top of the placement plate and close to the placement groove. The placement platform cooperates with the handle at the upper end of the endoscope body, and the placement groove cooperates with the connector at the bottom end of the endoscope body.

[0012] Preferably, a baffle is mounted on the bottom end of the placement plate via a rotating rod, and a drive rod is elastically and vertically slidably mounted inside the placement platform. The drive rod and the rotating rod cooperate through a guide structure. When the endoscope body is placed, the drive rod is adapted to move downward under the pressure of gravity of the endoscope body, thereby driving the baffle to rotate through the guide structure until it abuts against the connector.

[0013] Preferably, a sleeve is installed at the bottom end of the drive rod, and the guide structure includes a guide groove and a guide block. The guide groove is disposed inside the sleeve and has a spiral structure, and the guide block is disposed on the rotating rod and cooperates with the guide groove.

[0014] Preferably, the immediate pretreatment device for endoscopes further includes a lifting device and a disinfection tank. The lifting device is installed at the lower end of the movable frame, and the disinfection tank is placed on the lifting device and contains a pre-prepared cleaning solution. The top of the disinfection tank has a cover, and the top of the cover is provided with an openable receiving slot containing gauze soaked in the cleaning solution. During cleaning, the receiving slot is adapted to collect the cleaned contaminants and the used gauze.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: This invention, by incorporating a moving device and a clamp, allows for the automatic cleaning of the endoscope tubing during pre-treatment and cleaning. The clamp securely wraps the gauze soaked in cleaning solution around the tubing, while the moving device drives the clamp to move smoothly downwards along the tubing's axis. This reduces the workload of medical staff and improves the wiping effect. Attached Figure Description

[0027] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0029] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0030] One preferred embodiment of this application, such as Figures 1 to 10 As shown, an immediate pretreatment device for endoscopes includes a movable frame 1, a moving device 2, and a clamp 7. The movable frame 1 has a placement station 5 at its upper end for placing the endoscope body 6. The moving device 2 is mounted on the movable frame 1, and the clamp 7 is mounted on the moving device 2 and cooperates with the flexible tube 601 of the endoscope body 6.

[0031] Understandably, during the pretreatment and cleaning of the endoscope, the endoscope body 6 is first placed on the placement station 5, with the flexible tube 601 hanging vertically downwards. Then, gauze 8 soaked in cleaning solution is wrapped around the upper end of the flexible tube 601, and then clamp 7 is used to wrap the gauze 8, so that the gauze 8 can be stably positioned and wrapped around the outside of the flexible tube 601. Finally, the moving device 2 is activated to drive the clamp 7 to move axially downwards along the flexible tube 601. During this process, the gauze 8 can automatically wipe the outer surface of the flexible tube 601 under the action of the clamp 7, thereby effectively removing contaminants such as body fluids and tissue debris attached to the flexible tube 601.

[0032] Therefore, compared to manual wiping, this device automates the wiping process through mechanical drive, which not only reduces the labor intensity of medical staff but also avoids the problems of incomplete or missed wiping caused by the subjectivity of manual operation. It should be noted that this application mainly targets the pre-treatment stage of endoscopes, that is, the initial cleaning of the endoscope after use to remove most of the contaminants and lay the foundation for a more thorough disinfection and sterilization process, and does not replace the complete disinfection and sterilization steps.

[0033] In one embodiment of this application, such as Figure 2 and Figure 3 As shown, the moving device 2 includes a lead screw 201, a slider 202, and a driving device 203. The lead screw 201 is vertically fixed on the movable frame 1, the slider 202 is vertically slidably mounted on the movable frame 1, the clamp 7 is mounted on the end of the slider 202, and the driving device 203 is mounted on the slider 202 and cooperates with the lead screw 201. It can be understood that during cleaning, the slider 202 can move up and down along the axial direction of the lead screw 201 under the drive of the driving device 203.

[0034] As a further description of the above embodiments: as Figure 3 As shown, the drive device 203 includes a motor 2031, a threaded sleeve 2032, and a transmission assembly 2033. The threaded sleeve 2032 is rotatably mounted inside the slider 202 and cooperates with the lead screw 201. The motor 2031 is mounted on the top of the slider 202 and its output end is connected to the threaded sleeve 2032 through the transmission assembly 2033.

[0035] Understandably, when the motor 2031 starts, its output end transmits power to the threaded sleeve 2032 through the transmission component 2033, driving the threaded sleeve 2032 to rotate. Since the threaded sleeve 2032 is threadedly engaged with the lead screw 201, and the lead screw 201 is fixed, the rotating threaded sleeve 2032 will move axially relative to the lead screw 201, thereby causing the entire slider 202 and the clamp 7 mounted at the end of the slider 202 to move up and down along the axial direction of the lead screw 201. Furthermore, the threaded transmission between the threaded sleeve 2032 and the lead screw 201 enables precise control of the slider 202's movement speed, ensuring that the clamp 7 drives the gauze 8 to wipe the hose 601 stably and evenly.

[0036] like Figure 4 As shown, the clamp 7 includes a pair of half-hoops 701 and a limiting member 702. One end of the two half-hoops 701 is hinged together, and the other end is engaged by the limiting member 702, which can be a bolt and nut structure. Understandably, during use, medical personnel can open the two half-hoops 701, place the tubing 601 covered with gauze 8 between the two half-hoops 701, and then close the half-hoops 701. The limiting member 702 locks and fixes the free ends of the two half-hoops 701, thereby stably clamping the gauze 8 outside the tubing 601. This structural design makes the clamping and replacement of the gauze 8 convenient.

[0037] Further optimization, such as Figure 4 As shown, the slider 202 has an arc-shaped groove 10 at its end. The clamp 7 is elastically and slidably installed in the arc-shaped groove 10 by a spring. The clamp 7 is connected to the output end of the motor 2031 through an intermittent device 11. It can be understood that during cleaning, while the slider 202 moves down, the clamp 7 can also reciprocate along the axial direction of the hose 601 under the combined action of the intermittent device 11 and the spring force.

[0038] Specifically, when the motor 2031 drives the slider 202 to move downward, the intermittent device 11 periodically drives the clamp 7 to rotate against the spring force. When the intermittent device 11 stops driving, the clamp 7 rotates back to its original position under the spring force. This cycle repeats, allowing the clamp 7 to move the gauze 8 along the axial direction of the hose 601 while simultaneously rotating at a certain angle. This composite motion creates a relative spiral wiping trajectory between the gauze 8 and the outer surface of the hose 601. Compared to simple axial linear wiping, this significantly increases the contact area between the gauze 8 and the outer surface of the hose 601, thus more effectively removing contaminants adhering to the surface of the hose 601 in all directions and improving the pretreatment cleaning effect.

[0039] In one embodiment of this application, such as Figure 5 and Figure 6As shown, the intermittent device 11 includes an arc-shaped rack 1101 and an incomplete gear 1102. The rack 1101 is installed on the side of the clamp 7 (one of the half-hoops 701). The incomplete gear 1102 is rotatably installed on the slider 202 via a rotating shaft 12 and cooperates with the rack 1101. The rotating shaft 12 cooperates with the output end of the motor 2031 through the transmission assembly 2 9.

[0040] Understandably, after the motor 2031 starts, its output power is transmitted to the rotating shaft 12 through the transmission assembly 2 9, driving the incomplete gear 1102 to rotate synchronously. When the toothed section of the incomplete gear 1102 meshes with the arc-shaped rack 1101, the rack 1101 rotates and drives the clamp 7 to rotate along the arc-shaped groove 10. At this time, the spring is compressed and accumulates elastic potential energy. When the incomplete gear 1102 rotates to the point where the toothless section is opposite the rack 1101, the rack 1101 loses its driving force, and the clamp 7 rotates back to its initial position under the elastic force of the spring. Through the intermittent meshing of the incomplete gear 1102 and the rack 1101, the clamp 7 can achieve reciprocating rotation along the axial direction of the hose 601, thereby allowing the gauze 8 to wipe the outer surface of the hose 601 more thoroughly.

[0041] In a further preferred embodiment, the rotating shaft 12 is connected to the transmission assembly 9 via a one-way bearing 13. It should be noted that when the motor 2031 rotates in the first direction (clockwise), the one-way bearing 13 is engaged, allowing the clamp 7 to move downwards and rotate. When the motor 2031 rotates in the second direction (counterclockwise), the one-way bearing 13 is free, allowing the clamp 7 to move upwards and remain stationary in the circumferential direction.

[0042] It should be understood that the downward movement of clamp 7 is a process of cleaning hose 601. After cleaning hose 601, clamp 7 can be released and then moved upward to reset. At this time, clamp 7 does not need to rotate, and the main function of one-way bearing 13 is to reduce unnecessary mechanical wear and energy consumption.

[0043] It should be noted that this application does not specifically limit the structure of the transmission component 2033 and the transmission component 9 mentioned above. For example, they can be synchronous belt drives, gear drives, chain drives, etc.

[0044] In one embodiment of this application, such as Figure 6As shown, the placement station 5 includes a placement plate 501 and a placement platform 502. The placement plate 501 is horizontally fixed to the top of the movable frame 1 and has a placement groove 14 at its end. The placement platform 502 is installed on the top of the placement plate 501 and close to the placement groove 14. During placement: First, the connector 603 at the bottom of the endoscope body 6 is inserted into the placement groove 14. Then, the handle 602 at the top of the endoscope body 6 is lowered and placed in the slot on the placement platform 502. At this time, the connector 603 will move down and abut against the top of the placement plate 501, thereby achieving stable placement of the endoscope body 6.

[0045] Based on the above embodiments, instability may occur during placement: since the placement slot 14 is an open structure and the handle 602 is a cylindrical structure, if an external force is applied during placement, the handle 602 will rotate in the slot, thereby causing the connector 603 to rotate and disengage from the placement slot 14.

[0046] Therefore, in order to solve the above-mentioned technical problems, in one embodiment of this application, such as Figures 6 to 8 As shown, a baffle 15 is installed at the bottom of the placement plate 501 via a rotating rod 18, and a drive rod 16 is installed vertically and elastically inside the placement platform 502 via a spring. The drive rod 16 and the rotating rod 18 cooperate through a guide structure 19.

[0047] Understandably, when the handle 602 is placed in the slot of the placement stage 502, the weight of the handle 602 will press down on the drive rod 16, causing the drive rod 16 to move vertically downwards against the spring force. During the movement, the drive rod 16 drives the rotating rod 18 to rotate through the guide structure 19, thereby causing the baffle 15 to rotate towards the placement slot 14 until it abuts against the connector 603. When it is necessary to remove the endoscope body 6, simply lift the handle 602 upwards, and the drive rod 16 will return to its original position under the action of the spring force. The rotating rod 18 will then rotate in the opposite direction through the guide structure 19, and the baffle 15 will rotate back to its original position. Then, the connector 603 or the hose 601 can be removed from the placement slot 14, which is simple and convenient.

[0048] As a further description of the above embodiments: as Figure 7 and Figure 8 As shown, a sleeve 17 is installed at the bottom end of the drive rod 16. The guide structure 19 includes a guide groove 1901 and a guide block 1902. The guide groove 1901 is disposed inside the sleeve 17 and has a spiral structure. The guide block 1902 is disposed outside the rotating rod 18 and cooperates with the guide groove 1901.

[0049] Understandably, when the drive rod 16 moves downward under the gravity of the handle 602, the sleeve 17 at its bottom end moves downward simultaneously. The downward movement of the sleeve 17 will force the rotating rod 18 to rotate around its own axis through the cooperation of the spiral guide groove 1901 and the guide block 1902. This will cause the baffle 15 to rotate from the initial unobstructed position to a position that can laterally block the connector 603 in the placement slot 14, thereby effectively preventing the connector 603 from coming out of the placement slot 14 due to the rotation of the handle 602, and further improving the stability of the placement of the endoscope body 6.

[0050] Therefore, the limiting and unlocking of this baffle 15 are automatically completed by gravity and elasticity, requiring no additional manual operation and greatly simplifying the operation process for medical staff. Furthermore, during the rotation and limiting process, the baffle 15 also serves to align the endoscope body 6. That is, when the connector 603 is inserted into the placement groove 14, if its position is slightly tilted, the baffle 15, as it rotates towards the placement groove 14 and finally abuts against the connector 603, will exert a lateral pushing force on the connector 603, causing it to adjust to a more centered and stable position. This ensures that the tubing 601 remains vertically hanging, providing a good precondition for the subsequent precise clamping and wiping operations of the clamp 7.

[0051] In one embodiment of this application, such as Figure 9 and Figure 10 As shown, the immediate pretreatment device for endoscopes also includes a lifting device 4 and a sterilization tank 3. The lifting device 4 includes a telescopic component 401 (e.g., an electric push rod, hydraulic cylinder, or pneumatic cylinder) and a base 402. The telescopic component 401 is installed at the lower end of the movable frame 1, and the base 402 is installed at one end of the piston rod of the telescopic component 401. The sterilization tank 3 is placed at the top of the base 402. The top opening of the sterilization tank 3 has a cover 20, and the top of the cover 20 is provided with a receiving groove 21. The receiving groove 21 is also provided with a separate cover plate 22. Gauze 8 soaked in cleaning solution can be pre-placed in the receiving groove 21. Of course, the prepared cleaning solution can also be pre-placed in the sterilization tank 3.

[0052] Further optimization, such as Figure 6 and Figure 9 As shown, the placement plate 501 includes a front plate 5011 and a rear plate 5012. The rear plate 5012 is fixedly installed on the top of the movable frame 1, and the front plate 5011 is movably and adjustablely installed on the rear plate 5012. The placement station 5 is located on the rear plate 5012. It can be understood that after wiping the hose 601, the hose 601 can be separated from the clamp 7 by adjusting and moving the rear plate 5012. This prevents the clamp 7 from interfering with the subsequent cleaning of the hose 601, and also facilitates the upward repositioning of the clamp 7.

[0053] The working principle of this invention is as follows: ① First, place the endoscope body 6, after being removed from the patient, on the placement station 5, such as... Figure 6 As shown, under the gravity of the endoscope body 6, the baffle 15 will align and limit the endoscope body 6, allowing the flexible tube 601 to remain vertically hanging. ② Open the cover plate 22 on the cover 20, remove the gauze 8 soaked in cleaning solution from the receiving tank 21, and wrap the gauze 8 around the flexible tube 601 near the connector 603. Then close the two half-hoops 701 of the clamp 7, and lock the gauze 8 to the outside of the flexible tube 601 using the limiting member 702. Next, place the disinfection bucket 3 on the base 402, so that the receiving tank 21 corresponds directly below the flexible tube 601, thereby collecting the contaminants and liquids from subsequent cleaning. ③ Start the motor 2031 from the operation panel of the device. The output end of the motor 2031 drives the threaded sleeve 2032 to rotate through the transmission component 1 2033. The slider 202 then moves the clamp 7 downward along the axial direction of the lead screw 201. At the same time, the output end of the motor 2031 drives the incomplete gear 1102 to rotate through the transmission component 2 9. The incomplete gear 1102 intermittently meshes with the arc rack 1101, so that the clamp 7 reciprocates along the axial direction of the hose 601 under the cooperation of the spring, so as to realize the spiral wiping of the outer surface of the hose 601 by the gauze 8. ④ After wiping, loosen the limiting piece 702, open the clamp 7, remove the used gauze 8, and wipe the bottom end of the tube 601 with the back of the gauze 8 (the side of the gauze 8 that is not in contact with the tube 601), that is, wipe the tip of the endoscope body 6 in the direction of the nozzle. Finally, the used gauze 8 can be thrown into the receiving tank 21 or the medical waste bin; then operate the air and water supply button on the endoscope body 6 to repeatedly supply air and water for at least 10 seconds. ⑤ By adjusting the movable rear plate 5012, the hose 601 is separated from the clamp 7, and the opening of the disinfection tank 3 is aligned with the hose 601. The lifting device 4 is activated from the control panel, causing the telescopic component 401 to shorten, which in turn causes the piston rod to move the base 402 and the disinfection tank 3 upwards until the tip of the hose 601 is immersed in the pre-prepared cleaning solution in the disinfection tank 3. The suction button on the endoscope body 6 is then used to aspirate the cleaning solution until it flows into the suction tube. Finally, the endoscope body 6 is removed from the placement station 5, the waterproof endoscope cap is closed, and it is placed in a transport container for subsequent cleaning in the cleaning and disinfection chamber. Thus, through the above series of automated and semi-automated operations, this device can efficiently and conveniently complete the immediate pretreatment process of the inner and outer surfaces of the endoscope after use.
