Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a nasogastric endoscope anti-loop tube. Background Technology

[0002] The anti-loop tube for nasogastric endoscopy is a device used to assist in nasogastric endoscopy examinations and treatments.

[0003] Currently, the existing anti-looping tube for nasogastric endoscopes (patent number: CN204484045U) discloses an anti-looping tube for nasogastric endoscopes, which is mainly a sleeve that is fitted over the insertion part of the nasogastric endoscope. The distal end of the sleeve is about 20cm away from the lens of the nasogastric endoscope. A fixing member is connected to the sleeve, and the sleeve is firmly and tightly bound to the body of the nasogastric endoscope through the fixing member to prevent the sleeve from moving up and down along the body of the nasogastric endoscope. It can effectively increase the rigidity of the insertion part of the nasogastric endoscope and prevent it from looping in the stomach cavity during the insertion of the common bile duct.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were found: the anti-loop tube of the nasogastric endoscope is mainly composed of a sleeve and two fixing components. The two fixing components are set on the outside of the sleeve. The sleeve itself has a certain thickness. Adding two fixing components increases the thickness of the anti-loop tube, thereby increasing the discomfort of the user. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, this utility model provides a nasogastric endoscope anti-loop tube, which solves the technical problem that the thickness of the anti-loop tube is increased by adding two fixing parts, which increases the discomfort of the user when using the tube, since the tube itself has a certain thickness.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A nasogastric endoscope anti-loop tube includes two cannulas, with a flexible connecting tube between them. Intermediate tubes are fixedly connected to both ends of the flexible connecting tube. The two cannulas are fixedly connected to the outside of the two intermediate tubes. Each cannulas has an adhesive mechanism for securing it. Each adhesive mechanism includes a flexible connector, an adhesive layer, and release paper. There are two flexible connectors, both located on the outside of the cannulas. There are two adhesive layers, each laid on the inside of the two flexible connectors. There are two release papers, each adhered to the outside of the two adhesive layers. A pull ring is fixedly connected to the outside of each release paper.

[0008] Preferably, the flexible connecting tube has several support bars on its inner side and several fixing grooves on its inner side.

[0009] Preferably, each sleeve has an annular groove on its outer side, and an adjusting cylinder is slidably connected inside each annular groove. A flexible connector is fixedly installed on the outside of the adjusting cylinder. Each sleeve has a limit groove on one side corresponding to the annular groove, and a limit block is slidably connected inside each limit groove. The limit block is fixedly installed on the outside of the adjusting cylinder to adjust the overall length of the anti-loop tube.

[0010] Preferably, each sleeve is provided with a limiting protrusion on the side near the flexible connecting tube, and each sleeve has a groove inside. One end of the limiting protrusion is fixedly connected to the inside of the groove to increase the stability of the anti-loop tube installation.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Before using a nasogastric endoscope, place the cannula, flexible connecting tube, intermediate tube, and flexible connector onto the insertion part of the nasogastric endoscope. When the three parts are in the appropriate position, lift the flexible connector upwards to expose the release paper. At this time, use the pull ring to peel off the release paper to expose the adhesive layer. Then, reset the flexible connector so that the adhesive layer fits into the insertion part of the endoscope. At this time, the anti-loop tube is installed. The adhesive layer is used for fixation, avoiding the extra thickness added by the fixation component, making the overall structure lighter and thinner, and reducing the discomfort caused to the patient by the anti-loop tube during the examination.

[0013] Second, the flexible connecting tube allows the anti-loop tube to better conform to the physiological curvature of the human digestive tract. The difference in hardness between the transition sleeve and the flexible connecting tube, therefore, the cooperation between the intermediate tube and the flexible connecting tube enhances the overall flexibility of the anti-loop tube structure.

[0021] This application provides a nasogastric endoscope anti-loop tube, which effectively solves the technical problem that the thickness of the anti-loop tube increases due to the addition of two fixing members, which increases the user's discomfort. Example

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this embodiment effectively solves the problem that the thickness of the anti-loop tube increases due to the addition of two fixing members, which increases the user's discomfort. The overall idea is as follows:

[0023] To address the problems existing in the prior art, this utility model provides a nasogastric endoscope anti-loop tube, comprising two sleeves 1, with a flexible connecting tube 2 disposed between the two sleeves 1, and intermediate tubes 3 fixedly connected to both ends of the flexible connecting tube 2. The two sleeves 1 are respectively fixedly connected to the outside of the two intermediate tubes 3. The intermediate tubes 3 are more flexible than the sleeves 1 but less flexible than the flexible connecting tube 2. Each sleeve 1 is provided with an adhesive mechanism for fixing the sleeve 1 on its outside. Each adhesive mechanism includes a flexible connector 4, an adhesive layer 5, and a release paper 6. There are two flexible connectors 4, both of which are disposed on the outside of the sleeves 1. There are two adhesive layers 5, which are respectively laid on the inside of the two flexible connectors 4. There are two release papers 6, which are respectively adhered to the outside of the two adhesive layers 5.

[0024] The flexible connecting tube 2 has several support bars 8 on its inner side and several fixing grooves 9 on its inner side, with the support bars 8 fixedly connected inside the fixing grooves 9.

[0025] Each sleeve 1 has an annular groove 10 on its outside, and an adjusting cylinder 11 is slidably connected inside each annular groove 10. A flexible connector 4 is fixedly installed on the outside of the adjusting cylinder 11. Each sleeve 1 has a limiting groove 12 on one side corresponding to the annular groove 10. A limiting block 13 is slidably connected inside each limiting groove 12. The limiting block 13 is fixedly installed on the outside of the adjusting cylinder 11.

[0026] Each sleeve 1 is provided with a limiting protrusion 14 on the side near the flexible connecting tube 2. The limiting protrusion 14 is a rubber block with a certain elasticity. Each sleeve 1 has a groove 15 inside. One end of the limiting protrusion 14 is fixedly connected to the inside of the groove 15, and the other end of the limiting protrusion 14 extends outward.

[0027] Each release paper 6 is fixedly connected to a pull ring 7 on the outside. The pull ring 7 makes it easy for workers to pull the release paper 6 to expose the adhesive layer 5.

[0028] Cannula 1: Cannula 1 is made of medical rubber material with a certain degree of hardness, which can effectively increase the rigidity of the nasogastric endoscope insertion part and prevent the endoscope from bending excessively or getting stuck.

[0029] Flexible connecting tube 2: Adapts to physiological curvature, and can adjust the curvature of each segment of the cannula 1 according to the actual route of the nasogastric endoscope in the digestive tract to reduce pressure on the digestive tract;

[0030] Intermediate tube 3: The hardness difference between transition sleeve 1 and flexible connecting tube 2 reduces stress concentration and prevents breakage or deformation at the connection.

[0031] Flexible connector 4 and adhesive layer 5: Flexible connector 4 is made of softer medical rubber. When installing the anti-loop tube, the doctor can easily lift and reset it, and quickly fix the anti-loop tube to the nasogastric endoscope using adhesive layer 5.

[0032] Release paper 6: Prevents the adhesive layer 5 from being contaminated before use, ensures the adhesion of the adhesive layer 5 during installation, and guarantees the fixing effect;

[0033] Support bar 8: The support bar 8 is a reinforcing structure embedded in the inner wall of the flexible connecting pipe 2 to prevent the flexible connecting pipe 2 from undergoing excessive local deformation or collapse when subjected to external pressure;

[0034] Annular groove 10 and adjusting cylinder 11: Adjust the total length of the anti-loop tube to adapt to different inspection needs and improve versatility;

[0035] Limiting block 13 and limiting groove 12: limit the sliding range of adjusting cylinder 11 and prevent excessive movement that could cause adjusting cylinder 11 to fall off;

[0036] Limiting protrusion 14: The limiting protrusion 14 can be engaged with the natural folds of the endoscope insertion part to prevent axial displacement of the anti-loop tube and enhance stability. During the installation of the anti-loop tube, Figure 4 The sleeve 1 containing the middle limiting protrusion 14 is first installed by contacting the insertion part of the nasogastric endoscope.

[0037] Working principle:

[0038] First, before using the nasogastric endoscope, place the cannula 1, flexible connecting tube 2, intermediate tube 3, and flexible connector 4 on the insertion part of the nasogastric endoscope. When the three are moved to the appropriate position, lift the flexible connector 4 upward to expose the release paper 6. At this time, use the pull ring 7 to peel off the release paper 6 to expose the adhesive layer 5. Then reset the flexible connector 4 to make the adhesive layer 5 fit with the insertion part of the endoscope. At this time, the anti-loop tube installation is completed.

[0039] The second step is to adjust the overall length of the anti-loop tube before peeling off the release paper 6. Move the flexible connector 4 to drive the adjusting cylinder 11 to slide inside the annular groove 10, thereby adjusting the overall length of the anti-loop tube. After the adjustment is completed, peel off the release paper 6 and fix the anti-loop tube.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
