Description

TECHNICAL FIELD

[0001] The present specification relates to the field of medical devices, in particular to a complete drying reusable endoscope purifying device. BACKGROUND

[0002] In the medical field, especially in the reusable endoscope, the endoscope is inserted into the body for endoscopy, so the reusable endoscope should be purified after use to keep clean for the next use.

[0003] The existing purification treatment mainly has two ways, way one: as shown in the publication number JP3645010B2, through the manual cleaning of the perfusion device, because of the cleaning efficiency, the proportion of using this way is gradually reduced; way two: through the medical endoscope cleaning workstation, the main cleaning steps include pre-cleaning, leak detection, cleaning, soaking disinfection, rinsing and drying steps (generally divided into washing program, disinfection program and drying program), among them, the pre-cleaning should be carried out immediately after the endoscope is used, including flushing the air supply channel, water supply channel, suction channel and other channels, to remove the attached blood, mucus and tissue debris, to ensure the smoothness of the endoscope lumen; leak detection is to ensure that the endoscope has no leakage before cleaning and disinfection; cleaning and soaking disinfection make the endoscope reach the cleaning and disinfection standard, through the above steps, it is ensured that the endoscope can reach the appropriate cleaning and disinfection standard before and after use; rinsing is to remove the cleaning liquid residue, generally using flowing water to flush the outer surface, and then using a pressure gun to fill the pipeline with air, and wiping the outer surface; the drying step is to complete the rinsing, then use 70% to 90% ethanol or isopropyl alcohol (volatile) to flush the endoscope channel, and then use a high-pressure air gun to blow, to dry the air supply channel, water supply channel, suction channel and other channels of the endoscope, as shown in the publication number US20240215811A1, the flow control unit of the endoscope reprocessing device, the dedicated switchable valve integrated in the supply channel, the reprocessing program or reprocessing routine is provided to the flow control unit by the CPU of the endoscope reprocessing device, the treatment fluid can be a reprocessing fluid, such as a fluid for cleaning and / or a fluid for disinfection. By setting the dedicated switchable valve to a saving state, the treatment fluid consumption of the flow control unit can be significantly reduced. Some endoscope reprocessing devices, as shown in the publication numbers CN108387480B and CN115429922B, are provided with a chamber for placing the instrument (endoscope), the instrument is dried by controlling the pressure and temperature in the chamber (vacuum chamber), specifically, the chamber (vacuum chamber) can be heated by a heating element.

[0004] However, due to the long length of the endoscope channel, simple irrigation with ethanol or continuous drying with artificial clean air flow is prone to residual cleaning water; and the use of a chamber (vacuum chamber) to control pressure and temperature for drying the instrument is high in cost, and the heat cannot effectively act on the air supply channel, water supply channel and suction channel of the endoscope, incomplete drying can cause many problems, such as bacterial reproduction, residual moisture in the channel provides an ideal environment for bacterial growth, and residual live bacteria will rapidly reproduce and bacterialize the instrument, increasing the risk of patient infection; in addition, a long-term wet environment can damage the internal structure and performance of the endoscope and shorten its service life. Therefore, the drying link after the endoscope disinfection is very important, and thorough drying must be ensured to avoid the above problems

[0005] Therefore, it is necessary to provide an apparatus capable of ensuring complete drying of the endoscope and ensuring the safety of the patient and the reuse of the endoscope. Utility model content

DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the technical solutions of the embodiments of the present specification, the drawings needed to be used in the embodiment description will be briefly introduced as follows. Obviously, the drawings in the following description are only some examples or embodiments of the present specification, and for those skilled in the art, the present specification can also be applied to other similar scenarios without creative labor on the basis of these drawings. Unless it is clear from the language environment or otherwise stated, the same reference numbers in the drawings represent the same structures or operations.

[0024] It should be understood that the "system", "device", "unit" and / or "module" used herein is a method for distinguishing different components, elements, parts, sections or assemblies at different levels. However, if other words can achieve the same purpose, the words can be replaced by other expressions.

[0025] As shown in the specification and claims, unless the context clearly indicates otherwise, "one", "a", "an", and / or "the" do not refer to the singular, but can also include the plural. Generally speaking, the terms "comprise" and "include" only indicate the inclusion of the steps and elements explicitly identified, and these steps and elements do not constitute an exclusive list, and the method or device can also include other steps or elements.

[0026] As Figure 1As shown in some embodiments of the present disclosure, a dry and reusable endoscope device includes a gas input interface 1, a gas tube 2, a heating container 3, a gas output interface 4 and a setting unit 5. Clean compressed gas filtered by the gas input interface 1 enters the gas tube 2, which is wrapped in the heating container 3. The heating container 3 can heat the outside of the gas tube 2, thereby heating the clean compressed gas in the gas tube 2. The heated clean compressed gas flows out of the gas output interface 4 for dry use in the channel of the endoscope. During the above heating process, the user can set the temperature of the clean compressed gas in the gas tube 2 by operating the setting unit 5. Specifically, the setting unit 5 controls the heating container 3 through the controller to make the temperature in the gas tube 2 reach the set temperature. The setting unit 5 has a pressure gauge 6, a time setting unit 7 and a temperature setting unit 8. Through the embodiment, it is ensured that the gas reaches the preset temperature and is sent into different pipes of the endoscope. The clean and heated gas is automatically and continuously supplied to the endoscope pipe, which improves the influence of artificial interference factors such as artificial continuous drying time, quality influence and individual execution difference on the drying result, realizes rapid and uniform drying effect, and facilitates the user to operate the dry and reusable endoscope device.

[0027] As shown in some embodiments, Figure 2 The heating container 3 includes an outer shell and a heater arranged in the outer shell. Specifically, the heating container 3 is composed of a protective cover 12 and a heating wire 9. The heating wire 9 is fixedly wound on the gas tube 2. The heating wire 9 is uniformly and closely wound on the entire gas tube 2, which can realize uniform and rapid heating of the clean compressed gas in the gas tube 2. The protective cover 12 covers the entire heating wire 9 to prevent heat loss of the heating wire 9 and effectively improve the heating efficiency of the entire device.

[0028] In addition, the part of the gas tube 2 in the protective cover 12 is in the shape of an "arch". This arrangement can increase the length of the gas tube 2 in the protective cover 12, increase the contact area of the clean compressed gas in the gas tube 2 with the gas tube 2, and also enable more heating wires 9 to be wound on the gas tube 2, thereby significantly improving the heating efficiency. Understandably, the shape of the gas tube 2 is not limited to the "arch" shape, but can also be an "S" shape, a "Z" shape, etc., which can also achieve the above-mentioned purpose of improving the heating efficiency.

[0029] As shown in some embodiments, Figure 3 The heating container 3 includes an outer shell and a heater arranged in the outer shell. Specifically, the outer shell is a liquid tank 13, and the heater is composed of a heat-conducting liquid 10 and a heating rod 11. The heating rod 11 heats the heat-conducting liquid 10, and the entire gas tube 2 is immersed in the heat-conducting liquid 10. As the temperature of the gas tube 2 rises, the clean compressed gas in the gas tube 2 also rises to achieve the heating effect. The liquid heating method can make the heating of the gas tube 2 more uniform.

[0030] In addition, the air tube 2 is in the shape of an "arch" inside the liquid tank 13. This arrangement can increase the length of the air tube 2 inside the liquid tank 13, allowing the longer air tube 2 to be immersed in the heat-conducting liquid 10. The clean compressed gas inside the air tube 2 can increase the contact area with the air tube 2. This "arch" shape arrangement can also make full use of the space inside the liquid tank by arranging the heating rod 11 in the empty space of the air tube 2. This not only saves space, but also heats the heat-conducting liquid 10 evenly and fully. The heating of the entire air tube 2 can also be more uniform and faster.

[0031] Understandably, in some embodiments, the shape of the air tube 2 is not limited to the "bow" shape, but can also be "S" shaped, "Z" shaped, etc., which can also achieve the above-mentioned purpose of improving heating efficiency.

[0032] Understandably, in some embodiments, in addition to using the protective cover 12 and heating wire 9 and the heating rod 11 and heat-conducting liquid 10 as heating containers to heat the air pipe 2, the heating container can also be a heating blanket, heating belt, chemical heating pack and electric heating plate, etc., all of which can achieve heating of the air pipe 2.

[0033] like Figure 4 As shown, in some embodiments, the setting unit 5 includes a time setting unit 7 and a temperature setting unit 8. The time setting unit 7 includes a time display 15 and a time setting button 16. The time display 15 can be used to display the set temperature and the remaining time after the device starts working, allowing the operator to monitor the device's operation in real time. The temperature setting unit 8 includes a set temperature display 17, an actual temperature display 18, and a temperature setting button 19. By observing the two independent temperature display values ​​(set temperature display 17 and actual temperature display 18), the operator can more clearly observe the device's operating status. Both the time setting button 16 and the temperature setting button 19 include a down button for decreasing the set value and an up button for increasing the set value.

[0034] Understandably, the set temperature display 17 and the actual temperature display 18 can share a single display screen. After the set temperature is adjusted, the display screen automatically switches to show the actual temperature. Furthermore, the temperature setting unit 8 may also include an alarm module; when the actual temperature exceeds the set temperature, the device will emit a buzzer alarm.

[0035] In addition, a pressure gauge 6 can be installed on the setting unit 5 to detect the pressure of the clean compressed gas in the trachea 2. The operator can determine whether the gas pressure in the trachea 2 meets the requirements based on the pressure detection value. Furthermore, a start button 14 can be installed on the setting unit 5 to turn this reusable endoscope purification device on and off. When not in use, the entire device can be turned off by using the start button 14.

[0036] likeFigure 5 As shown, in some embodiments, the multiplex endoscope purifying device further comprises a connecting pipe 20, the connection between the multiplex endoscope purifying device and the endoscope is connected through the connecting pipe 20, the connecting pipe 20 comprises a connecting pipe input interface 21, the input pipe interface 21 is connected with the gas output interface 4, specifically, the connecting pipe input interface is a quick plug interface, facilitating the plugging between the multiplex endoscope purifying device and the connecting pipe 20. The other end of the connecting pipe is connected with the suction interface, the auxiliary water supply interface and the water and gas interface on the light guide joint 27 of the endoscope through the suction output interface 24, the auxiliary water supply output interface 25 and the water and gas output interface 26, so as to transmit the heated clean compressed gas to the pipeline in the endoscope which needs to be dried. In addition, the connecting pipe 20 further comprises a first three-way pipe 22 and a second three-way pipe 23, the first three-way pipe 22 is used to split and connect the suction connecting pipe 32 for connecting the suction interface of the endoscope and the suction output interface 24, the second three-way pipe 23 is used to split and connect the auxiliary water supply connecting pipe 33 for connecting the auxiliary water supply interface of the endoscope and the auxiliary water supply output interface 25, and the water and gas connecting pipe 34 for connecting the water and gas interface of the endoscope and the water and gas output interface 26. By using the two three-way pipe structures, the output part of the connecting pipe 20 is divided into three output interfaces, which are respectively connected with different pipelines of the endoscope, so that the simultaneous drying of different pipelines of the endoscope can be realized.

[0037] It can be understood that, in some embodiments, the connecting pipe has and only has two output interfaces, that is, the connecting pipe has only one three-way pipe connection, for example, the input interface of the connecting pipe is connected with the gas output interface 4, and the two output interfaces are connected with any two of the suction interface, the auxiliary water supply interface and the water and gas interface, so as to realize the drying treatment of two pipelines.

[0038] In addition, the pipeline split by the first three-way pipe 22 is used to be connected with the suction interface on the endoscope, which can increase the amount of clean compressed gas in the suction connecting pipe 32, and the amount of clean compressed gas entering the suction interface of the endoscope is greater than the amount of clean compressed gas entering the water and gas interface and the auxiliary water supply interface in unit time, because there is more residual liquid in the suction channel in the endoscope, so that different pipelines in the endoscope can be dried almost simultaneously, so as to save time and cost.

[0039] In some embodiments, the inner diameter of the suction connecting pipe 32 is greater than that of the auxiliary water supply connecting pipe 33, and the inner diameter of the suction connecting pipe 32 is also greater than that of the water and gas connecting pipe 34.

[0040] The beneficial effects that may be brought by the embodiments of the present application include but are not limited to:

[0041] 1. The heated clean compressed gas is respectively introduced into different wet pipelines in the endoscope which need to be dried, so that the complete drying of the pipeline can be realized, and the breeding and reproduction of bacteria can be avoided;

[0042] 2. Drying the moist passage inside the endoscope separately eliminates the need to place the entire endoscope in a dedicated chamber to wait for the internal passage to dry, thus shortening the overall drying process time and saving equipment resources.

[0043] 3. By setting the time and temperature, different time and temperature parameters can be set for different types of endoscopes. The time and temperature display of the setting unit can accurately control the drying process, which is beneficial to the operator.

[0044] It should be noted that different embodiments may produce different beneficial effects. In different embodiments, the beneficial effects may be any one or a combination of the above, or any other possible beneficial effects.
