Description

Technical Field

[0001] The present invention belongs to the technical field of medical device logistics, and particularly relates to an endoscope transfer device. Background Art

[0002] A flexible endoscope is an endoscope used for medical diagnosis and treatment. Compared with traditional rigid endoscopes, it is more flexible and can better adapt to the complex anatomical structures and curved parts inside the human body. However, due to its flexible characteristics, it is prone to contamination and infection risks. Therefore, after use, a series of disinfection and cleaning are required to ensure safety and effectiveness during the next use. Inside a hospital, different areas have different functions and levels. The consulting room is the main area where doctors and patients come into contact, and medical devices such as endoscopes are used here. However, since these devices are prone to contamination and infection risks, cleaning and disinfecting them in the consulting room may pose a threat to other patients and doctors. Therefore, the disinfection and cleaning process of flexible endoscopes requires transferring the contaminated endoscopes after use from the consulting room to the disinfection and cleaning room. However, this transfer process is not suitable for directly using common transfer trolleys for the following reasons:

[0003] 1. The transfer trolley occupies the corridor floor passage, affecting traffic and work efficiency, and wasting the hospital's scarce human resources;

[0004] 2. Cross-infection risk: During the transfer process, the flexible endoscope may be at risk of contamination and infection. Especially when accidents or improper operations occur during the transfer, it may lead to the spread of pathogens and cross-infection.

[0005] 3. Endoscope damage and failure: During the transfer process, the flexible endoscope may be damaged and fail due to improper operations and inappropriate environmental factors, resulting in waste of consumables and reduced usage efficiency.

[0006] 4. Legal liability issues: If accidents or improper operations occur during the transfer, it may lead to medical accidents and legal disputes, causing unnecessary losses and risks to the hospital and doctors.

[0007] In summary, there is currently a need for a device that can clean and safely transfer flexible endoscopes. Summary of the Invention

[0008] The object of the present invention is to provide an endoscope transfer device. When the endoscope needs to be cleaned in the consulting room, the conversion slideway is switched to the cleaned endoscope slideway, so that the cleaned endoscope suspended by the hook slides into the consulting room by gravity; when the endoscope to be cleaned needs to be transported out of the consulting room, the conversion slideway is switched to the soiled endoscope slideway, so that the endoscope to be cleaned suspended by the hook slides out of the consulting room by gravity. And when the conversion slideway is switched to the soiled endoscope slideway, the locking unit on the cleaned endoscope slideway will pop up to prevent the cleaned endoscope from sliding into the consulting room.

[0009] The technical solution adopted by the present invention to solve the above problems is: an endoscope transfer device, comprising:

[0010] A cleaned endoscope slideway for transporting the cleaned endoscope;

[0011] A soiled endoscope slideway located below the cleaned endoscope slideway and used for transporting the endoscope to be cleaned;

[0012] A hook for hanging the endoscope on the cleaned endoscope slideway or the soiled endoscope slideway;

[0013] A conversion slideway for switching the state of connection between the cleaned endoscope slideway and the consulting room, or between the soiled endoscope slideway and the consulting room;

[0014] A locking unit for locking the end of the cleaned endoscope slideway when the conversion slideway is switched to the state of connection between the soiled endoscope slideway and the consulting room.

[0015] A further preferred technical solution lies in that: the locking unit includes a trigger part for contacting the end of the conversion slideway, and a stop part that pops up after the trigger part contacts the end of the conversion slideway and is used for locking the hook.

[0016] A further preferred technical solution lies in that: the trigger part includes a contact column and an axial return spring for pushing the contact column outwards.

[0017] A further preferred technical solution lies in that: the trigger part further includes an arc-shaped edge provided at the outer end of the contact column and used for contacting the end of the conversion slideway.

[0018] A further preferred technical solution lies in that: the trigger part further includes a pressing groove provided at the upper end of the contact column and used for pressing the stop part upwards; the stop part includes a pressing block installed in the pressing groove and a limiting column provided on the pressing block.

[0019] A further preferred technical solution lies in that: the trigger part further includes a limiting groove provided on the upper side of the upper end of the limiting column and used for engaging the hook.

[0020] A further preferred technical solution lies in that: the trigger part further includes a radial return spring for pushing the limiting column downwards.

[0021] A further preferred technical solution is that the mirror cleaning slide is arranged obliquely, and the consulting room is located at the lower end of the mirror cleaning slide.

[0022] A further preferred technical solution is that the dirty mirror slide is arranged obliquely, and the consulting room is located at the upper end of the clean mirror slide.

[0023] A further preferred technical solution is that the clean mirror slide is located above the dirty mirror slide.

[0024] In summary, the present invention has the following advantages:

[0025] 1. The conversion slide can avoid cross infection between the dirty mirror slide and the clean mirror slide. After the endoscope is used in the clinic, the dirty mirror is put back on the dirty mirror slide. The conversion slide can disconnect the dirty mirror slide from the clinic, thus avoiding the risk of cross infection between the dirty mirror and the clean mirror;

[0026] 1. The clean mirror slide is located above the dirty mirror slide, so the pollutants on the endoscope to be cleaned will not contaminate the clean mirror slide during transportation, thus achieving the clean and dirty separation effect;

[0027] 2. The length of the conversion slide is short, so each time the conversion slide transports the endoscope room to be cleaned, it can be disinfected in a simple way to facilitate the subsequent switch to the cleaning slide to receive the cleaned endoscope;

[0028] 3. When the endoscope is still considered to have problems after cleaning and needs to be transferred directly from the clean endoscope slide to the dirty endoscope slide, the conversion slide can disconnect the clean endoscope slide from the clinic, thereby preventing the endoscope from being mistakenly transferred to the clinic and increasing the safety of endoscope transfer;

[0029] 4. When the conversion slide is switched to the dirty endoscope slide, the locking unit can block the clean endoscope slide from transporting the cleaned endoscope into the clinic, thereby preventing cross infection between the endoscope to be cleaned and the cleaned endoscope;

[0030] 5. The locking unit 5 can also improve the safety of endoscope delivery, preventing the endoscope from flying into the consulting room without the guide of the conversion slide, causing harm to the personnel in the consulting room, or breaking the endoscope;

[0031] 6. A limit groove is provided on the stop portion to prevent the cleaned endoscope installed on the hook from rushing into the consulting room as soon as the conversion slide is switched to the cleaning mirror slide, so that the staff in the consulting room cannot greet it in time and the endoscope is broken.

Detailed implementation manners

[0042] The present invention will be further described in detail below with reference to the accompanying drawings.

[0043] This specific embodiment is only an interpretation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.

[0044] Embodiment 1:

[0045] In this embodiment, the endoscope transfer device includes: clean mirror slideway 1, dirty mirror slideway 2, conversion slideway 3, hook 4, locking unit 5;

[0046] Wherein the locking unit 5 includes: triggering part 501, stop part 502;

[0047] Among them, the trigger part 501 includes: a contact column 501a, an axial return spring 501b, an arc edge 501c, and an extrusion groove 501d;

[0048] Among them, the stop part 502 includes: an extrusion block 502a, a limit column 502b, and a radial return spring 502d.

[0049] Reference Figure 1 , showing a schematic structural diagram of an endoscope transfer device, where the clean endoscope slideway 1 is located above, and the dirty endoscope slideway 2 is located below. In this way, the pollutants on the endoscope to be cleaned will not contaminate the clean endoscope slideway 1 or the cleaned endoscope transported on the clean endoscope slideway 1 during transportation, achieving the effect of separating cleaning and contamination. The main body of the conversion slideway 3 is a small section of track with the same specifications as the clean endoscope slideway 1 and the dirty endoscope slideway 2, and a rotating shaft that is rotatably connected to the track and fixed on a certain fixed surface or device is provided in the center of the track. The track switches between the clean endoscope slideway 1 and the dirty endoscope slideway 2 by rotating on the rotating shaft. There are two limit points in the rotating shaft to align the conversion slideway 3 with the clean endoscope slideway 1 or the dirty endoscope slideway 2.

[0050] In summary, placing the clean endoscope slideway for transporting the cleaned endoscope above the dirty endoscope slideway for transporting the endoscope to be cleaned can bring the following benefits:

[0051] 1. Avoid cross-infection: Placing the clean endoscope slideway above the dirty endoscope slideway can effectively avoid cross-infection between the endoscope to be cleaned and the cleaned endoscope. Because the endoscope to be cleaned usually has a high risk of bacterial and viral contamination. If the clean endoscope slideway is placed below the dirty endoscope slideway, the cleaned endoscope may be contaminated, increasing the risk of cross-infection.

[0052] 2. Improve work efficiency: Placing the clean endoscope slideway above the dirty endoscope slideway can make it easier to take out the cleaned endoscope, thereby improving the efficiency of endoscope transfer. If the clean endoscope slideway is placed below the dirty endoscope slideway, then the cleaned endoscope needs to be taken out from below, which will consume more time and energy.

[0053] 3. Facilitate management: Placing the clean endoscope slideway above the dirty endoscope slideway can make the endoscope transfer system easier to manage. Because the endoscope to be cleaned and the cleaned endoscope are stored on different slideways respectively, it is easier for managers to classify and manage the endoscopes, thereby improving the efficiency and accuracy of endoscope transfer management.

[0054] In summary, setting a conversion slideway between the clean endoscope slideway and the dirty endoscope slideway to switch the connection state between the clean endoscope slideway and the dirty endoscope slideway and the consulting room can bring the following benefits:

[0055] 1. Avoid cross-infection: During the transfer of the endoscope, the conversion chute can prevent cross-infection between the contaminated endoscope chute and the clean endoscope chute. After the endoscope is used in the consulting room, the contaminated endoscope is placed back on the contaminated endoscope chute, and the conversion chute can disconnect the contaminated endoscope chute from the consulting room, thus avoiding the risk of cross-infection between the contaminated endoscope and the clean endoscope.

[0056] 2. Facilitate maintenance: When the transfer system fails or needs maintenance, the conversion chute can disconnect the transfer system from the consulting room, facilitating the maintenance personnel to perform internal maintenance. Without the conversion chute, the maintenance personnel need to perform maintenance in the consulting room, which will affect the normal working order of the hospital.

[0057] 3. Improve safety: The conversion chute can improve safety during the transfer of the endoscope. When the endoscope after cleaning is considered still problematic by the consulting room and needs to be directly transferred from the clean endoscope chute to the contaminated endoscope chute, the conversion chute can disconnect the clean endoscope chute from the consulting room, thus preventing the mis-transfer of the endoscope to the consulting room and increasing the safety of endoscope transfer.

[0058] Specifically, as can be seen in the figure, the length of the conversion chute 3 is relatively small. Therefore, after the conversion chute 3 transports the endoscope to be cleaned to the endoscope room each time, it can be disinfected in a simple way to facilitate subsequent switching to the clean endoscope chute 1 to receive the endoscope after cleaning.

[0059] Reference Figure 2 , which shows a schematic diagram of the conversion chute switching from the clean endoscope chute 1 to the lower contaminated endoscope chute 2. It can be seen that after the conversion, the locking unit 5 protrudes and blocks the clean endoscope chute 1 to prevent the endoscope after cleaning from sliding down. Specifically, because there is a distance between the consulting room and the disinfection and cleaning room, there is a delay in communication, a delay in the process of the disinfection and cleaning room searching for the endoscope, and a delay in the process of transferring the endoscope. Sometimes, it will cause the process of the consulting room receiving the endoscope after cleaning and the process of transferring the endoscope to be cleaned to occur simultaneously. For example, when the consulting room requests the disinfection and cleaning room to transfer the endoscope, and at this time, there is also a corresponding endoscope to be cleaned in this consulting room that needs to be sent to the disinfection and cleaning room. At this time, the conversion chute 3 switches to the contaminated endoscope chute 2, then the endoscope after cleaning sliding towards the consulting room through the clean endoscope chute 1 cannot enter the consulting room and may even fall onto the lower contaminated endoscope chute 2. To avoid this phenomenon, after the conversion, the locking unit 5 protrudes and blocks the clean endoscope chute 1 to prevent the endoscope after cleaning from sliding down into the consulting room or falling onto the contaminated endoscope chute 2.

[0060] Specifically, generally, when the communication between the consulting room and the disinfection and cleaning room is smooth, during the process of the conversion chute 3 switching to the contaminated endoscope chute 2, the disinfection and cleaning room will not transport the endoscope after cleaning to the consulting room, and the consulting room will not often transfer the endoscope to be cleaned when it needs to receive the endoscope after cleaning. Therefore, the locking unit 5 more plays an insurance role. It is not necessary for the locking unit 5 to prevent the endoscope after cleaning from sliding towards the consulting room every time the conversion chute 3 switches to the contaminated endoscope chute 2.

[0061] Reference Figure 3 , which shows a schematic structural diagram of the locking unit 5. It can be seen that the locking unit 5 includes an axial triggering part 501 and a radial positioning part 502. When the end of the conversion slideway 3 presses the triggering part 501 into the inner cavity of the clean mirror slideway 1, the positioning part 502 also enters the inner cavity of the clean mirror slideway 1 accordingly. At this time, the positioning part 502 does not affect the process of the hook 4 sliding on the clean mirror slideway 1 to the conversion slideway 3.

[0062] Reference Figure 4 , which shows Figure 3 a schematic diagram in which the end of the conversion slideway in

[0063] leaves the clean mirror slideway, causing the triggering part to release outward and push up the positioning part. It can be seen that when the end of the conversion slideway 3 leaves the triggering part 501, the triggering part 501 will pop out of the inner cavity of the clean mirror slideway 1 and transform into a state to be triggered. At this time, the positioning part 502 pops out of the inner cavity of the clean mirror slideway 1 under the action of the force transformed by the triggering part 501 to the radial direction, so as to block the process of the hook 4 sliding on the clean mirror slideway 1 to the conversion slideway 3.

[0064] In summary, by setting the locking unit 5 at the end of the clean mirror slideway 1 close to the consulting room, when the conversion slideway 3 switches to the dirty mirror slideway 2, the locking unit 5 pops up and blocks the clean mirror slideway 1 from transporting the cleaned endoscope into the consulting room, which can bring the following benefits:

[0065] 1. By setting the locking unit 5 at the end of the clean mirror slideway 1 close to the consulting room, when the conversion slideway 3 switches to the dirty mirror slideway 2, the locking unit 5 can block the clean mirror slideway 1 from transporting the cleaned endoscope into the consulting room, thus avoiding cross-infection between the endoscope to be cleaned and the cleaned endoscope.

[0066] 2. The locking unit 5 can prevent the endoscope on the clean mirror slideway 1 from falling or being left behind midway, ensuring the continuity and stability of the endoscope transmission.

[0067] 3. The locking unit 5 can also improve the safety of the endoscope transmission, preventing the endoscope from flying into the consulting room without the guidance of the conversion slideway 3, causing harm to the personnel in the consulting room or damaging the endoscope.

[0068] Reference Figure 5 , which shows a schematic diagram of the hook sliding to the positioning part and being stuck by the limiting groove thereon. It can be seen that when the hook 4 is blocked by the positioning part 502, it will be stuck by the limiting groove 502c on the positioning part 502 and cannot move on the clean mirror slideway 1.

[0069] Reference Figure 7, which shows a schematic diagram of observing the cleaning mirror slide axially. The endoscope structure suspended below the hook 4 is omitted here. Among them, the cleaning mirror slide 1 shows a rectangular cross-section. It is easy to think that the rectangular cross-section can also be a circular structure. Among them, the rectangular slide has a larger internal space and can accommodate more mechanical structures, such as the locking unit 5.

[0070] Reference Figure 8 , which shows the specific structure of the locking unit 5. Among them, the contact post 501a is a post with a rectangular or circular cross-section. An arc-shaped edge 501c is provided at the outer end of the contact post 501a. The arc-shaped edge 501c is a hemispherical shape as a whole. A pressing groove 501d is provided on the contact post 501a. The lower end surface of the pressing groove 501d has a gentle surface, and the outer side surface has a steep surface, and the gentle surface is inclined downward from the inside to the outside. In addition, there is an axial return spring 501b for applying a continuous outward force to the contact post 501a.

[0071] Reference Figure 9 , which shows the specific structure of the locking unit 5. Among them, the lower end of the pressing block 502a has the same gentle surface as the pressing groove 501d. When the contact post 501a moves outward, the gentle surface at the lower end of the pressing groove 501d will fit the gentle surface at the lower end of the pressing block 502a, and the gentle surface is inclined downward from the inside to the outside. Under the extrusion, the limit post 502b will move upward and thus protrude from the inner cavity of the cleaning mirror slide 1. The limit groove 502c is provided on the side surface of the top end of the limit post 502b, and the reference notch faces the direction of the cleaned endoscope. The radial return spring 502d always has a downward elastic force on the limit post 502b. When the gentle surface at the lower end of the pressing groove 501d leaves the gentle surface at the lower end of the pressing block 502a, under the action of the radial return spring 502d, the limit post 502b moves downward and resets.

[0072] Specifically, under the combined action of the gentle surface at the lower end of the pressing groove 501d and the radial return spring 502d, when the contact post 501a is pushed, it will continuously compress the radial return spring 502d, making its elastic force increase more and more until the force transmitted to the gentle surface at the lower end of the pressing groove 501d is balanced with the outward thrust of the axial return spring 501b, so that the contact post 501a will not be pushed out by the axial return spring 501b.

[0073] Embodiment 2

[0074] In this embodiment, the endoscope transmission device is basically the same as that in Embodiment 1, and the differences are as follows:

[0075] Among them, the stop portion 502 further includes a limit groove 502c.

[0076] Reference Figure 6 , which shows Figure 5Schematic diagram of the end of the middle conversion slideway 3 pushing the triggering part 501 into the cavity of the cleaning mirror slideway 1. It can be seen that even if the triggering part 501 is pushed back into the cavity of the cleaning mirror slideway 1 again, under the engagement of the limiting groove 502c and the hook 4, the stopping part 502 still cannot fall back into the cavity.

[0077] In summary, setting the limiting groove 502c on the stopping part 502 can bring the following benefits:

[0078] 1. It avoids the situation that as soon as the conversion slideway 3 switches to the cleaning mirror slideway 1, the endoscope after cleaning installed on the hook 4 rushes into the consulting room, causing the endoscope to be damaged because the personnel in the consulting room have no time to receive it.

[0079] 2. Since the conversion slideway 3 is relatively short, the personnel in the consulting room can manually remove the hook 4 from the limiting groove 502c, which does not affect the normal reception of the endoscope after cleaning in the consulting room.

[0080] In addition, the same or similar reference numerals are used as much as possible in the drawings and the description to refer to the same or similar parts or steps.
