DETAILED DESCRIPTION OF THE EMBODIMENTS
[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0033] The core of the present utility model is to provide a medical trolley, which can ensure the dryness of the plug of the light guide part of the endoscope. Another core of the present utility model is to provide an endoscope system including the above-mentioned medical trolley, which has the same beneficial effects as the aforementioned medical trolley.
[0034] Please refer to Figure 1 and Figure 2 , an embodiment of the present utility model provides a medical trolley, including a trolley 1, a detection device and a drying device 3. The trolley 1 is provided with a light guide part placement seat 11, and the light guide part placement seat 11 is used for placing the light guide part 51 of the endoscope (as shown in Figure 3 ); both the detection device and the drying device 3 are arranged on the trolley 1. The detection device is used to detect whether the light guide part 51 is placed in place; the drying device 3 is connected to the detection device, and the drying device 3 is used to dry the plug 511 of the light guide part 51 after the detection device detects that the light guide part 51 is placed in place.
[0035] It should be noted that after the endoscope is cleaned and disinfected in the cleaning and disinfection machine, the medical staff will take out the endoscope and place it on the trolley 1. At this time, the light guide part 51 of the endoscope is placed on the light guide part placement seat 11 for use, and the doctor will use the endoscope to examine the patient after arriving.
[0036] In the embodiment of the present utility model, after the light guide part 51 of the endoscope is placed on the light guide part placement seat 11, the detection device automatically detects whether the light guide part 51 is placed in place. When the detection device detects that the light guide part 51 is placed in place, it sends a signal that the light guide part 51 is placed in place to the drying device 3, and the drying device 3 is used to dry the plug 511 of the light guide part 51, so that the plug 511 of the light guide part 51 is kept in a dry state, so that the endoscope can be directly used to examine the patient after the doctor arrives. Since the plug 511 of the light guide part 51 of the endoscope has been dried by the drying device 3 before the doctor uses the endoscope, when the plug 511 of the light guide part 51 of the endoscope is inserted into the host and the endoscope is powered on to make it work, it is not easy to cause an electrolytic reaction, thereby improving the service life of the plug 511 of the light guide part 51 of the endoscope, which is beneficial to protecting the long-term reliable operation of the host and the endoscope.
[0037] It can be seen that for this medical trolley, as long as the light guide part 51 is placed on the light guide part placement seat 11 and the detection device can automatically detect that the light guide part 51 is placed in place, the drying device 3 can be started to dry the plug 511 of the light guide part 51, and the waiting time before the doctor arrives can be used to dry the light guide part 51 of the endoscope, without affecting the actual use time of the endoscope. Moreover, without additional operations, the dryness of the plug 511 of the light guide part 51 can be ensured, and the endoscope can be prevented from being powered on under wet or water-carrying conditions. In addition, it can also prevent the phenomenon of missed drying caused by forgetting to turn on the drying device 3 when relying on manual opening.
[0038] It should be noted that the specific structure of the light guide part placement seat 11 in this embodiment is not limited, as long as the light guide part placement seat 11 can place the light guide part 51.
[0039] In addition, in some embodiments, the trolley 1 is further provided with an operation part placement seat 12 for placing the operation part of the endoscope. When the endoscope is placed on the trolley 1, the operation part is placed on the operation part placement seat 12, and the light guide part 51 is placed on the light guide part placement seat 11, so that the whole endoscope is in a suspended state. The specific structure of the operation part placement seat 12 in this embodiment is not limited, as long as the operation part placement seat 12 can place the operation part of the endoscope.
[0040] Furthermore, the specific number of the light guide part placement seats 11 in the embodiments of the present utility model is not limited. The number of the light guide part placement seats 11 can be one, or at least two. When the number of the light guide part placement seats 11 is at least two, that is, at least two endoscopes can be placed on the trolley 1 at the same time. Correspondingly, the number of the detection device and the drying device 3 is one or at least two respectively, that is, the number of the detection device, the drying device 3 and the light guide part placement seats 11 is the same, and the three are in one-to-one correspondence. When at least two endoscopes are placed on the trolley 1 at the same time, two or more detection devices can be used to respectively detect whether the light guide parts 51 of the corresponding endoscopes are placed in place, and two or more drying devices 3 can be used to respectively dry the plugs 511 of the corresponding light guide parts 51. For example, as Figures 1 to 3 shown, in some embodiments, the trolley 1 is provided with two light guide part placement seats 11, two detection devices and two drying devices 3.
[0041] Of course, in some embodiments, the number of the detection device and the drying device 3 can also be different from the number of the light guide part placement seats 11, as long as the detection device can locate the light guide part placement seat 11 where the light guide part is placed and enable the drying device 3 to dry the light guide part.
[0042] In addition, the specific structure of the detection device and its detection principle and the like in this embodiment are not limited, as long as the detection device can detect whether the light guide part 51 is placed in place.
[0043] Please combine Figures 1 to 3, in some embodiments, the detection device includes a pressure sensor 2, which is disposed on the light guide part placement seat 11 and is used to detect the pressure between the light guide part 51 and the light guide part placement seat 11, so as to determine whether the light guide part 51 is placed in place according to this pressure. It can be understood that the pressure situation between the light guide part 51 and the light guide part placement seat 11 directly reflects the installation situation of the light guide part 51. When the pressure between the light guide part 51 and the light guide part placement seat 11 does not meet the preset conditions, it indicates that the light guide part 51 is not placed in place. When the pressure between the light guide part 51 and the light guide part placement seat 11 meets the preset conditions, it indicates that the light guide part 51 is placed in place. Therefore, in this embodiment, the pressure sensor 2 is used to detect the pressure between the light guide part 51 and the light guide part placement seat 11 to determine whether the light guide part 51 is placed in place. This solution is simple and easy to implement.
[0044] Considering the convenience of setting the pressure sensor 2, further, as Figure 2 shown, in some embodiments, the side wall of the light guide part placement seat 11 is provided with an installation hole 111 penetrating through its wall thickness, and the pressure sensor 2 is embedded in the installation hole 111. It can be understood that in order for the pressure sensor 2 to detect the pressure between the light guide part 51 and the light guide part placement seat 11, the pressure sensor 2 needs to be built into the inner wall of the light guide part placement seat 11. At the same time, considering the convenience of installing the pressure sensor 2, in this embodiment, an installation hole 111 penetrating through the inner and outer surfaces of the side wall is opened on the side wall of the light guide part placement seat 11, and the pressure sensor 2 is embedded in the installation hole 111. On the one hand, it is convenient to install the pressure sensor 2 from the outside of the light guide part placement seat 11. On the other hand, it is convenient for the pressure sensor 2 to be exposed on the inner side surface of the light guide part placement seat 11, so that the pressure sensor 2 can detect the pressure between the light guide part 51 and the light guide part placement seat 11.
[0045] Of course, in some other embodiments, the detection device can also be other solutions, which are not limited herein, as long as the detection device can detect whether the light guide part 51 is placed in place. For example, the detection device includes a laser sensor, and the laser sensor is used to detect the existence of the light guide part 51, so as to determine whether the light guide part 51 is placed in place.
[0046] In addition, in the above various embodiments, the specific installation position of the drying device 3 is not limited, as long as the drying device 3 can dry the plug 511 of the light guide part 51. It can be understood that the drying device 3 needs to have a preset relative position relationship with the light guide part placement seat 11, so that when the light guide part 51 is placed in place on the light guide part placement seat 11, the drying device 3 can be aligned with the plug 511 of the light guide part 51 to dry it.
[0047] As Figures 1 to 3As shown, in some embodiments, the drying device 3 is located above the light guide part placement seat 11, and the drying device 3 has a downward hot air outlet, so as to dry the plug 511 of the light guide part 51 by using the hot air coming out of the hot air outlet. That is to say, in this embodiment, the hot air outlet of the drying device 3 blows hot air downward, and the hot air from top to bottom is used to dry the plug 511 of the light guide part 51 located below the drying device 3, which is beneficial to quickly dry the end of the plug 511, with high drying efficiency and being convenient and fast.
[0048] Of course, in some other embodiments, the following solution may also be adopted: the drying device 3 is located at the side of the light guide part placement seat 11, and the drying device 3 has a hot air outlet facing obliquely upward to the light guide part placement seat 11, so as to use the hot air outlet to blow hot air obliquely upward to the light guide part placement seat 11, and dry the plug 511 from the side of the plug 511 of the light guide part 51.
[0049] When the drying device 3 is located above the light guide part placement seat 11, for the convenience of setting the drying device 3, please continue to refer to Figures 1 to 3 , in some embodiments, the trolley 1 is provided with a bracket 4, the bracket 4 is provided with a suspension opening, and the drying device 3 is inserted into the suspension opening. That is to say, in this embodiment, the drying device 3 is mounted at a suitable height position by using the bracket 4, so that the drying device 3 has a suitable distance from the top of the light guide part placement seat 11, so as to avoid the drying device 3 interfering with the insertion of the light guide part 51 into the light guide part placement seat 11. At the same time, the drying device 3 has a good drying effect on the plug 511. In addition, by inserting the drying device 3 into the suspension opening of the bracket 4, the connection between the drying device 3 and the bracket 4 is realized, which is convenient for installing the drying device 3, and the structure is simple.
[0050] It should be noted that the specific structure of the bracket 4 in this embodiment is not limited, as long as the bracket 4 can play a role in connecting the drying device 3 and the trolley 1, and make the drying device 3 located at a suitable position above the light guide part placement seat 11. Please refer to Figure 2 and Figure 3 , in some embodiments, the bracket 4 includes a fixing part 41, a mounting part 42 and a connecting part 43 connecting the fixing part 41 and the mounting part 42. The fixing part 41 is fixedly connected to the trolley 1, the mounting part 42 is provided with the above-mentioned suspension opening for mounting the drying device 3, and the connecting part 43 connects the fixing part 41 and the mounting part 42 together. At the same time, it ensures that the fixing part 41 and the mounting part 42 each have a suitable position, so as to facilitate the connection between the fixing part 41 and the trolley 1, and make the drying device 3 located at a suitable position through the mounting part 42. Further, in some embodiments, the fixing part 41, the connecting part 43 and the mounting part 42 form a structure similar to a Z shape, the fixing part 41 and the mounting part 42 are respectively vertically connected to the connecting part 43, and the fixing part 41 and the mounting part 42 respectively extend in opposite directions with respect to the extending direction of the connecting part 43.
[0051] It should be noted that in the above embodiments, the specific structure of the drying device 3 is not limited, as long as the drying device 3 can dry the plug 511 of the light guide part 51.
[0052] In some embodiments, the drying device 3 includes a housing, a heater, and a blowing device. The housing is provided with a hot air outlet; the heater and the blowing device are both arranged inside the housing. The heater is used to heat the air inside the housing to a preset temperature; the blowing device is used to blow the heated air to the hot air outlet of the light guide part 51. That is to say, when the drying device 3 works, the air inside the housing is heated to the preset temperature by the heater, and the heated hot air is blown to the hot air outlet of the light guide part 51 by the blowing device, so that the hot air blows to the surface of the plug 511 of the light guide part 51 after coming out of the hot air outlet, causing the moisture on the surface of the plug 511 of the light guide part 51 to evaporate and ensuring the dryness of the plug 511 of the light guide part 51.
[0053] In addition, in order to facilitate controlling the drying time of the drying device 3 according to different requirements, in some embodiments, the drying device 3 includes a drying time setting module for setting different drying times. That is to say, in this embodiment, the drying time of the drying device 3 is adjustable, and the user can change the drying duration of the drying device 3 for the plug 511 of the light guide part 51 by adjusting the setting parameters of the time setting module. For example, the drying time of the drying device 3 on the trolley 1 can be set according to the drying effect of the cleaning and disinfection machine in each hospital. When the drying effect of the cleaning and disinfection machine is good, the drying duration of the drying device 3 can be set shorter; when the drying effect of the cleaning and disinfection machine is poor, the drying duration of the drying device 3 needs to be set longer.
[0054] In addition, for the convenience of use, in some embodiments, the drying device 3 includes a memory module for memorizing the setting parameters during the last drying. That is to say, in this embodiment, the memory module memorizes the setting parameters during the last drying. In this way, when the drying device 3 is started again, it directly works according to the setting parameters during the last drying, avoiding the need to set the setting parameters of the drying device 3 every time, such as the heating temperature, drying time, etc.
[0055] In addition, as Figure 2 and Figure 3 shown, in some embodiments, the drying device 3 includes an indicator 31 for giving a drying completion prompt after the drying of the plug 511 of the light guide part 51 is completed. That is to say, after the drying device 3 finishes drying, the drying completion indication is given through the indicator 31 to prompt the user that the drying of the plug 511 of the light guide part 51 has been completed, and the endoscope can be directly powered on for operation, which is convenient for the user to confirm that the plug 511 of the light guide part 51 has been dried.
[0056] It should be noted that the specific structure of the indicator 31 is not limited in this embodiment. For example, the indicator 31 can be an indicator light. When the drying device 3 finishes drying the plug 511 of the light guide portion 51, the indicator light turns on to indicate that the drying is completed. In other embodiments, the indicator 31 can also be a sound reminder, such as a buzzer. When the drying device 3 finishes drying the plug 511 of the light guide portion 51, the buzzer emits a beeping sound to indicate that the drying is completed. Of course, the indicator 31 can also be a broadcaster or a display device, etc., which reminds the user that the drying device 3 has completed drying the plug 511 of the light guide portion 51 by broadcasting or displaying the completion of drying.
[0057] In addition to the above-mentioned medical trolley, the present utility model also provides an endoscope system including the medical trolley disclosed in the above embodiment.
