Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an irrigation and cleaning assembly for endoscopes. Background Technology

[0002] An endoscope is a flexible endoscope used for the examination or treatment of human cavities, such as a gastroscope, duodenoscope, and colonoscope. While its material is soft and flexible, its luminal structure is complex (e.g., water / air delivery tubes, suction tubes, auxiliary water delivery tubes), and its surface is prone to forming biofilms (stubborn attachments composed of bacteria, mucus, etc.), which are difficult to penetrate with conventional water flow and chemical disinfectants, requiring special cleaning processes.

[0003] Existing endoscopic irrigation and cleaning equipment has the following problems when processing two or more endoscopes simultaneously:

[0004] (1) High operational complexity: Medical staff need to spend a lot of time and energy to correctly connect each irrigation channel, which can easily lead to connection errors, resulting in the irrigation and cleaning work not being able to be carried out normally, and may even damage the endoscope equipment.

[0005] (2) Risk of cross-infection: Improper connection of irrigation channels between different endoscopes or backflow of fluid during cleaning can easily lead to cross-infection, posing a serious threat to the patient's health. In addition, it is difficult to effectively ensure the airtightness between irrigation channels, which further increases the risk of cross-infection.

[0006] (3) Low accuracy and efficiency of leak detection: During endoscope leak detection, problems such as unstable pressure and insensitive leak detection often occur, which makes it impossible to detect the leak point of the endoscope in a timely and accurate manner, affecting the safety and service life of the endoscope.

[0007] In summary, how to provide an irrigation component that solves any of the above-mentioned technical problems is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0020] The second port of the side leakage inlet connector is connected to the second port of the side leakage outlet connector to form a side leakage detection channel.

[0021] Preferably, all the irrigation inlet connectors, all the irrigation outlet connectors, the side leakage air inlet connectors, and the side leakage air supply connectors in each group of connectors are marked with different colors.

[0022] Preferably, the side of the motherboard is provided with a plurality of side insertion holes spaced apart along its length, for inserting all of the water outlet connectors and the air leakage connectors respectively;

[0023] The bottom of the motherboard is provided with a plurality of bottom insertion holes spaced apart along its length, for all of the irrigation water inlet connectors and the side leakage air inlet connectors to be inserted, and the plurality of bottom insertion holes and the plurality of side insertion holes are connected to each other. A sealing ring is provided between the irrigation water inlet connector, the side leakage air inlet connector and the bottom insertion holes.

[0024] Preferably, the motherboard can be divided into a first board and a second board along its thickness direction.

The first insertion hole and the second insertion hole are connected to form the bottom insertion hole, and the side insertion hole is provided on one side of the first board in the width direction.

[0025] Preferably, the second plate is provided with a nail head receiving groove along its thickness direction, and the first plate is provided with a nut rod receiving groove along its thickness direction;

[0026] The head of the first nut abuts against the end face of the second plate facing away from the first plate, and the nut shank of the first nut extends into the nut shank receiving groove;

[0027] The screw head is fitted into the screw head receiving groove, and the screw shank passes through the second plate and is threadedly connected to the nut shank.

[0028] Preferably, the connection method between the irrigation water inlet connector, the side leakage air inlet connector, and the main board is the same;

[0029] The irrigation inlet connector is inserted into the first socket and the two are tightly fitted together. The first end of the irrigation inlet connector extends out of the first socket in a direction away from the second plate.

[0032] Preferably, both the irrigation channel and the side leakage detection channel have an inverted L-shaped structure.

[0033] It should be noted that an endoscope has three main cavities (water / air supply channel, suction channel, and auxiliary water supply channel, etc.). Therefore, each set of connectors must have at least three pairs of interconnected irrigation inlet and outlet connectors to irrigate and clean an endoscope. The following explanation uses the irrigation and cleaning of the three main cavities of an endoscope as an example:

[0034] When using the endoscope irrigation and cleaning assembly provided by this utility model, in each set of connectors, the first port of the three irrigation water inlet connectors is connected to the pump valve used for irrigation and cleaning, and the second port is connected to the three main cavities of an endoscope, so that the three independent irrigation channels irrigate and clean the three main cavities of the endoscope respectively, thereby avoiding leakage of liquid or gas between the irrigation channels and reducing the risk of cross-infection.

[0035] In addition, the two sets of connectors are located on both sides of the motherboard width. The three irrigation outlet connectors in one set are dedicated to connecting one endoscope, while the three irrigation connectors in the other set are dedicated to connecting another endoscope. This allows for independent control of irrigation and cleaning of the two endoscopes. Therefore, the two sets of connectors in different positions make it convenient for medical staff to correctly connect the irrigation channels, greatly simplifying the operation process and avoiding improper connection of irrigation channels of different endoscopes, further reducing the risk of cross-infection.

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] The core of this invention is to provide an irrigation and cleaning assembly for endoscopes. When processing two endoscopes simultaneously, this assembly facilitates the correct connection of each irrigation channel by medical staff, and prevents liquid or gas leakage between the irrigation channels, thereby reducing the risk of cross-infection.

[0050] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this application and simplifying the description, and does 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. Therefore, it should not be construed as a limitation on this application. In addition, "first," "second," "third," and "fourth" are only used to describe effects and should not be construed as indicating or implying relative importance.

[0051] Please refer to Figure 1 and Figure 2 This application provides an irrigation and cleaning assembly for endoscopes, including a main board 1 and two sets of connectors. The two sets of connectors are respectively located on both sides of the main board 1 in the width direction. Each set of connectors includes at least three irrigation inlet connectors 2 and at least three irrigation outlet connectors 3.

[0052] At least three irrigation inlet connectors 2 are arranged at intervals along the length of the main board 1, and each irrigation inlet connector 2 is inserted into the bottom of the main board 1 with its first port extending out of the main board 1.

[0053] At least three irrigation outlet connectors 3 are arranged at intervals along the length of the main board 1, and each irrigation outlet connector 3 is inserted into one side of the main board 1 with its first port extending out of the main board 1.

[0054] The second port of each irrigation inlet connector 2 is connected to the second port of an irrigation outlet connector 3 to form an independent irrigation channel 4.

[0055] It should be noted that the endoscope has three main cavities (water / air supply channel, suction channel, auxiliary water supply channel, etc.). Therefore, each set of connectors must have at least three pairs of interconnected irrigation inlet connectors 2 and irrigation outlet connectors 3 to irrigate and clean an endoscope. Of course, if each set of connectors has more than three pairs of interconnected irrigation inlet connectors 2 and irrigation outlet connectors 3, it can irrigate and clean other cavities besides the three main cavities, making the irrigation and cleaning assembly suitable for endoscopes with complex structures and ensuring the comprehensiveness of the irrigation and cleaning assembly.

[0056] Each set of connectors includes a hollow tubular structure with open ends for gas-liquid flow, comprising both the inlet connector 2 and the outlet connector 3. The inlet connector 2 is inserted into the bottom of the main board 1, with its first port extending beyond the main board 1 for easy connection to the pump valve used for irrigation cleaning. The outlet connector 3 is inserted into one side of the main board 1, with its first port extending beyond the main board 1 for easy connection to a cavity of the endoscope. The second ports of the inlet connector 2 and the outlet connector 3 are connected, forming an independent irrigation channel 4. Figure 4 As shown. Since each set of connectors has at least three pairs of connected irrigation inlet connectors 2 and irrigation outlet connectors 3, each set of connectors has at least three irrigation channels 4, and at least three irrigation channels 4 independently irrigate and clean each cavity of the endoscope.

[0057] Therefore, the endoscope irrigation and cleaning assembly provided in the above embodiments has the following effects:

[0058] First, it facilitates medical staff to correctly connect each irrigation channel 4: three irrigation outlet connectors 3 in one set of connectors are specifically used to connect one endoscope, and three irrigation connectors in another set of connectors are specifically used to connect another endoscope. This allows for independent control of irrigation and cleaning of the two endoscopes, ensuring that medical staff can easily and accurately connect each irrigation channel 4, thereby improving the accuracy and efficiency of the operation.

[0059] Secondly, it reduces the risk of cross-infection: At least three irrigation channels 4 independently irrigate and clean each cavity of the endoscope, preventing liquid or gas leakage between the channels 4 and reducing the risk of cross-infection. Furthermore, accurate connection of each irrigation channel 4 by medical staff avoids improper connection between irrigation channels 4 of different endoscopes, further reducing the risk of cross-infection.

[0060] Based on the above embodiments, as a further preferred embodiment, the connectors are provided in two or more groups. Some groups of connectors are located on one side of the width direction of the motherboard 1 and are arranged at intervals along the length direction of the motherboard 1, while other groups of connectors are located on the other side of the width direction of the motherboard 1 and are arranged at intervals along the length direction of the motherboard 1.

[0061] Understandably, two or more sets of connectors are suitable for long mainboard 1. Adding one more set of connectors allows for the simultaneous cleaning of one more endoscope, enabling the irrigation and cleaning assembly to simultaneously irrigate and clean two or more endoscopes, thereby batch irrigating and cleaning endoscopes and greatly improving cleaning efficiency.

[0062] It should be noted that endoscopes are high-end consumable medical devices that are subject to fatigue, aging, and damage. Therefore, it is necessary to regularly check for side leakage of endoscopes. If side leakage occurs, it will cause disinfectant and other liquids to damage and corrode the endoscope, reducing its service life. It will also cause the risk of infection due to microorganisms left on the endoscope due to incomplete cleaning.

[0063] To achieve endoscopic leakage detection, as a further preferred embodiment based on the above-described embodiments, please refer to... Figure 1 and Figure 2 Each set of connectors also includes a side leakage inlet connector 5 and a side leakage outlet connector 6; the side leakage inlet connector 5 is inserted into the bottom of the main board 1 and its first port extends out of the main board 1; the side leakage outlet connector 6 is inserted into one side of the main board 1 and its first port extends out of the main board 1; the second port of the side leakage inlet connector 5 is connected to the second port of the side leakage outlet connector 6 to form a side leakage detection channel.

[0064] Both the side-leakage inlet connector 5 and the side-leakage outlet connector 6 adopt a hollow tubular structure with openings at both ends to facilitate gas flow. The side-leakage inlet connector 5 is inserted into the bottom of the main board 1, with its first port extending out of the main board 1 for easy connection to the leak detection instrument. The side-leakage outlet connector 6 is inserted into the side of the main board 1, with its first port extending out of the main board 1 for easy connection to the side-leakage interface on the endoscope. The second ports of the side-leakage inlet connector 5 and the side-leakage outlet connector 6 are connected, forming a side-leakage detection channel. In this way, the leak detection instrument applies air pressure to the endoscope through the side-leakage detection channel, accurately identifying damage or sealing failure in the outer layer of the endoscope, thereby achieving side-leakage detection of the endoscope.

[0065] It should be noted that the side leakage air inlet connector 5 and at least three irrigation water inlet connectors 2 in each group of connectors are arranged side by side along the length of the main board 1, and the side leakage air supply connector 6 and at least three irrigation water outlet connectors 3 in each group of connectors are also arranged side by side along the length of the main board 1, so as to facilitate medical staff to accurately connect each channel.

[0066] Based on the above embodiments, please refer to Figure 4 As a further preferred design, both the irrigation channel 4 and the side leakage detection channel (not shown) are inverted L-shaped. This design has the following advantages:

[0067] First, the inverted L-shaped structure, through its curved design, can guide the flow direction of gas or liquid and reduce resistance, which is beneficial to improving rinsing efficiency.

[0068] Secondly, it can prevent gas or liquid deposits from blocking the irrigation channel 4 or the side leakage detection channel, thereby improving the reliability and stability of the irrigation cleaning component and reducing maintenance costs.

[0069] Third, it has strong structural stability and can withstand large impacts without easily deforming or loosening, further improving the reliability and stability of the irrigation and cleaning components. Especially for the side leakage detection of endoscopes, the stable installation of the side leakage detection channel can avoid pressure leakage or gas purity reduction due to loose interfaces, ensuring sensitive leakage detection.

[0070] Based on the above embodiments, as a further preferred embodiment, each group of connectors has different color markings for all irrigation inlet connectors 2, all irrigation outlet connectors 3, side leakage air inlet connectors 5, and side leakage air supply connectors 6.

[0071] Understandably, the endoscope has different functional channels, including three main cavities: a water / air supply channel, a suction channel, and a secondary water supply channel, as well as a side-leak interface. Each irrigation water inlet connector 2, irrigation water outlet connector 3, side-leak air inlet connector 5, and side-leak air supply connector 6 has its own color-coded markings, which further ensures that medical staff can accurately connect the various channels, improving the accuracy and efficiency of the operation.

[0072] Taking the cleaning of the three main cavities of an endoscope as an example, the three irrigation inlet connectors 2 are respectively labeled as irrigation inlet connector 21 for the water / air supply pipeline, irrigation inlet connector 22 for the suction pipeline, and irrigation inlet connector 23 for the auxiliary water supply pipeline. The three irrigation outlet connectors 3 are respectively labeled as irrigation outlet connector 31 for the water / air supply pipeline, irrigation outlet connector 32 for the suction pipeline, and irrigation outlet connector 33 for the auxiliary water supply pipeline.

[0073] More preferably, the side leakage air inlet connector 5 and the side leakage air supply connector 6 adopt irrigation connectors with different structures, and the irrigation water inlet connector 2 and the irrigation water outlet connector 3 also adopt irrigation connectors with different structures. Thus, through different structural designs, it can be further ensured that medical staff can accurately connect each channel, thereby improving the accuracy and efficiency of operation.

[0074] Based on the above embodiments, as a further preferred embodiment, the side of the motherboard 1 is provided with a plurality of side insertion holes spaced apart along its length direction, and all the water outlet connectors 3 and the air leakage connectors 6 are inserted into the plurality of side insertion holes to realize the installation of the water outlet connectors 3 and the air leakage connectors 6.

[0075] The bottom of the motherboard 1 is provided with multiple bottom insertion holes spaced apart along its length. All the water inlet connectors 2 and the side leakage air inlet connectors 5 are inserted into the multiple bottom insertion holes to realize the installation of the water inlet connectors 2 and the side leakage air inlet connectors 5.

[0076] Multiple bottom insertion holes and multiple side insertion holes are connected to each other to enable all irrigation inlet connectors 2 and irrigation outlet connectors 3 to be connected in pairs to form multiple irrigation channels 4, and the side leakage air inlet connector 5 and the side leakage air supply connector 6 to be connected to form a side leakage detection channel.

[0077] Based on this, a sealing ring 11 is installed between each irrigation inlet connector 2 and the bottom insertion hole, and between each side leakage air inlet connector 5 and the bottom insertion hole, such as Figure 4 As shown, this design prevents leakage and backflow of liquids or gases between channels, effectively reducing the risk of cross-infection.

[0078] Based on the above embodiments, as a further preferred embodiment, the motherboard 1 can be divided into a first board 7 and a second board 8 along its thickness direction, such as... Figure 4 As shown, the first plate 7 has a first insertion hole along its thickness direction, and the second plate 8 has a second insertion hole along its thickness direction. The first insertion hole and the second insertion hole are connected to form a bottom insertion hole, and the side insertion hole is located on one side of the first plate 7 in the width direction. It should be noted that, as can be seen from the above description, there are multiple bottom insertion holes. It is easy to see that there also need to be multiple first insertion holes on the first plate 7 and multiple second insertion holes on the second plate 8, and every two first insertion holes and two second insertion holes are connected to form a bottom insertion hole.

[0079] The above-mentioned structural design of the motherboard 1 has the following effects: First, the motherboard 1 can be split into a first board 7 and a second board 8 to facilitate the disassembly and assembly of each board connector; Second, it facilitates regular cleaning and maintenance of the bottom and side sockets, avoiding the presence of foreign objects in each socket that would affect the cleaning effect.

[0080] Based on the above embodiments, considering the detachable connection between the first plate 7 and the second plate 8, as a further preferred embodiment, the second plate 8 is provided with a nail head receiving groove along its thickness direction, and the first plate 7 is provided with a nut rod receiving groove along its thickness direction.

[0081] The head of the first nut 9 abuts against the end face of the second plate 8 facing away from the first plate 7, and the nut shank of the first nut 9 extends into the nut shank receiving groove; the head of the screw 10 is fitted into the screw head receiving groove, and the screw shank of the screw 10 passes through the second plate 8 and is threadedly connected to the nut shank.

[0082] Specifically, such as Figure 5 As shown, the head of the first nut 9 abuts against the upper end face of the second plate 8, the shank of the first nut 9 extends into the shank receiving groove, the head of the screw 10 is fitted into the head receiving groove, and the screw shank of the screw 10 penetrates through the upper end face of the second plate 8 and is inserted into the shank of the first nut 9, and is threadedly connected to the inner wall of the shank of the first nut 9, thereby fastening the first plate 7 and the second plate 8 together. It should be noted that the first nut 9 can be a hand-tightened Torx nut 9.

[0083] The above method of connecting the first plate 7 and the second plate 8 has the following effects: First, when disassembling and assembling the main board 1, it is only necessary to manually tighten the nut head of the first nut 9, thereby realizing quick disassembly and assembly of the main board 1; Second, the use of the first nut 9 and screw 10 for fastening can improve the strong clamping force, so that the first plate 7 and the second plate 8 are firmly connected, so that the main board 1 as a whole can withstand a large impact force, and thus be able to withstand pressure changes within a certain range, ensuring the reliable stability of the irrigation cleaning component.

[0084] Preferably, the screw 10 and the first nut 9 of the threaded connection are located in the middle of the main board 1 (first plate 7 and second plate 8) to avoid interference with the two sets of joints.

[0085] Based on the above embodiments, considering the connection method between the irrigation water inlet connector 2 and the main board 1, as a further preferred embodiment, the irrigation water inlet connector 2 is inserted into the first socket and the two are tightly fitted together. The first end of the irrigation water inlet connector 2 extends out of the first socket in the direction away from the second plate 8. The second end of the irrigation water inlet connector 2 is inserted into the second socket and a sealing ring 11 is provided between the two. The second end is provided with an outer edge 12, which abuts against the end face of the first plate 7 facing the second plate 8.

[0086] Specifically, such as Figure 4As shown, the first plate 7 and the second plate 8 are arranged from bottom to top, and the irrigation water inlet connector 2 is inserted into the first socket. The second end of the irrigation water inlet connector 2 is inserted upwards into the second socket, and an annular groove is provided on the outer wall of the second end near its second port. The sealing ring 11 is engaged in the annular groove and tightly fits against the inner wall of the second socket to form a seal, preventing gas or liquid from leaking or flowing back between the irrigation water inlet connector 2 and the second socket. Furthermore, the second end has an outer edge 12, which abuts against the upper surface of the first plate 7. The outer edge 12 further prevents gas or liquid from leaking or flowing back through the gap between the irrigation water inlet connector 2 and the second socket. Preferably, the outer edge 12 is welded to the first plate 7, ensuring a secure installation of the irrigation water inlet connector 2. Alternatively, a threaded connection between the irrigation water inlet connector 2 and the first socket can also ensure a secure installation. Additionally, the first end of the irrigation water inlet connector 2 extends downwards out of the first socket for easy connection to the pump valve used for irrigation cleaning.

[0087] Therefore, the above-mentioned connection method between the irrigation inlet connector 2 and the main board 1 can improve the installation firmness of the irrigation inlet connector 2, and the irrigation inlet connector 2 can withstand pressure changes within a certain range, ensuring the reliable and stable operation of the irrigation cleaning component. On the other hand, the sealing ring 11 and the outer edge 12 on the irrigation inlet connector 2 work together to prevent liquid or gas leakage and backflow between the channels, effectively reducing the risk of cross-infection.

[0088] The connection method between the side leakage air inlet connector 5 and the main board 1 is the same as the connection method and effect between the irrigation water inlet connector 2 and the main board 1, and will not be described again here.

[0089] Based on the above embodiments, and considering the installation method between the irrigation assembly and the cleaning tank 14, as a further preferred option, please refer to... Figures 3-7 The lower end face of the first plate 7 is provided with a sealing gasket 13. The sealing gasket 13 is used to press between the first plate 7 and the bottom of the cleaning tank 14. The first ends of the irrigation water inlet connector 2 and the side leakage air inlet connector 5 are arranged to pass through the sealing gasket 13 and the bottom of the cleaning tank 14 in sequence, so as to facilitate connection with the pump valve used for irrigation cleaning.

[0090] It should be noted that the cleaning tank 14 contains cleaning fluid, and the endoscope is placed in the cleaning tank 14 during cleaning. The sealing gasket 13 can further seal the gap between the irrigation water inlet connector 2, the side leakage air inlet connector 5, and the second socket, thereby further preventing liquid or gas leakage and backflow between the various channels and effectively reducing the risk of cross-infection.

[0091] Therefore, the sealing ring 11, outer edge 12 and sealing gasket 13 on the irrigation water inlet connector 2 or the side leakage air inlet connector 5 can form a highly airtight structure, so that there will be no leakage or backflow of liquid or gas between the channels, which significantly reduces the risk of cross-infection.

[0092] For the specific connection method of the sealing gasket 13, please refer to [reference needed]. Figure 3 and Figure 7 The head of the bolt 15 is fitted into the first plate 7, and the bolt 15 passes through the lower end face of the first plate 7, the sealing gasket 13 and the bottom of the cleaning tank 14 in sequence, and is fastened to the cleaning tank 14 by the second nut 16.

[0093] In summary, the endoscopic irrigation and cleaning assembly of this application has the following advantages:

[0094] First, the multiple irrigation channels and side leakage detection channels are all designed independently, enabling independent control of irrigation and cleaning of two endoscopes, which greatly simplifies the operation process and reduces the probability of connection errors.

[0095] Second, the allocation of each channel is clear. At least three irrigation channels and side leakage detection channels are clearly defined for the leak detection, water / air delivery, suction, and auxiliary water delivery channels of one endoscope. Through color markings, shape design, and unique layout of interface positions, it can be ensured that medical staff can accurately connect each channel, thereby improving the accuracy and efficiency of the operation.

[0096] Third, the highly airtight structure prevents leakage and backflow of liquids or gases between the channels, significantly reducing the risk of cross-infection.

[0097] Fourth, the components in the irrigation and cleaning assembly are firmly connected and can withstand pressure changes within a certain range, ensuring the reliability and stability of the irrigation and cleaning operation.

[0098] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0099] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
