Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a visual enema device. Background Technology

[0002] Enemas, as a key technique in clinical treatment and perioperative bowel preparation, have indications covering both therapeutic and diagnostic fields. Therapeutic applications include incomplete intestinal obstruction, inflammatory bowel disease, cirrhosis-related complications (such as endotoxemia and hepatic encephalopathy), chronic constipation, and pelvic inflammatory disease; diagnostic applications focus on bowel cleansing before colonoscopy and abdominal / pelvic surgery. Existing technologies, such as the integrated anal gas and stool drainage enema device proposed in patent CN214911329U, integrate an enema fluid storage tank, drainage belt, and multi-lumen catheter system (including a first liquid-blocking valve to control the enema fluid flow and a second liquid-blocking valve to regulate the direction of excretion), achieving simultaneous lubrication and drainage, thus improving clinical convenience. However, this device still has the following technical bottlenecks:

[0003] 1. Risks of blind insertion: The depth of anal cannula insertion depends on the operator's experience (usually <15cm), lacks objective positioning methods, and is prone to mucosal damage due to differences in rectal anatomy (such as the double-curved structure of the sacral flexure and perineal flexure), especially for those with insufficient operating experience.

[0004] 2. Limitations in the assessment of cleansing effect: Postoperative bowel cleanliness can only be indirectly judged by the patient's defecation. Patients with functional constipation or anal sphincter dysfunction need repeated enemas due to incomplete defecation, but there is a lack of real-time visual monitoring of the intestines to accurately adjust the enema parameters.

[0005] In summary, there is an urgent need to develop enema devices that integrate real-time image guidance to reduce operational risks and improve the accuracy of cleaning assessments. Utility Model Content

[0006] This invention overcomes the shortcomings of the prior art and provides a visual enema device, which helps to reduce operational risks and facilitates the reassessment of intestinal conditions.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] A visual enema device includes an enema inner tube, which comprises a silicone flexible tube segment and a silicone rigid tube segment connected in communication; the end of the silicone flexible tube segment is provided with a fish-mouth arc flushing opening, and drainage openings are symmetrically opened on both sides thereon.

[0009] It also includes a visualization component, which comprises a grip, flexible optical fiber, and a camera module, wherein:

[0010] One end of the flexible optical fiber is connected to the gripping part, and the other end extends to the silicone tube section and is fixedly connected to the camera module;

[0011] The camera module is connected to the display screen in real time via a flexible optical fiber, and its lens is close to the front of the fish mouth arc flushing opening.

[0012] Furthermore, the silicone rigid tube section is provided with a drainage interface on the outside, which is connected to the drainage tube. The drainage interface is connected to one end of the drainage tube by thread or snap-fit, and the other end of the drainage tube is connected to the enema fluid storage bag.

[0013] Furthermore, the length of the silicone rigid tube section is 20±2cm, the length of the silicone flexible tube section is 5±1cm, and the axial distance from the center of the drainage interface to the end of the fish mouth arc flushing opening is 15±1cm.

[0014] Furthermore, the drainage interface is provided with an annular valve assembly on the side away from the drainage opening. The annular valve assembly is composed of several circumferentially distributed elastic silicone sheets, and the center formed by the several elastic silicone sheets allows the flexible optical fiber to pass through.

[0015] Furthermore, the front end of the gripping part is also provided with a sleeve, and the front end of the sleeve is provided with a clamping plate fixed on the flexible optical fiber; the enema internal sleeve is provided with a trumpet-shaped opening, and a limiting part is provided on the inner side of the trumpet-shaped opening; when the visualization component is assembled with the enema internal sleeve, the sleeve is located in the trumpet-shaped opening, and the clamping plate is located on the side of the limiting part near the fish mouth arc flushing opening.

[0016] Furthermore, the outer diameter of the silicone rigid tube section is 0.8±0.1cm, the wall thickness is 0.1±0.02cm, and its hardness is Shore A type 70-80 degrees, while the hardness of the silicone flexible tube section is Shore A type 30-40 degrees.

[0017] Furthermore, the silicone hose segment is designed to gradually narrow towards the fish-mouth arc-shaped rinsing opening.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model discloses a visual enema device. By incorporating a visualization component, the insertion process is visualized, which avoids the risk of perforation caused by enema due to variations in rectal structure and length. Furthermore, the intestinal condition can be reassessed through the photographed images after enema cleaning. The front end of the enema tube is a silicone flexible tube, which is less likely to damage the intestinal mucosa compared to ordinary enema tubes. In addition, the fish-mouth arc-shaped rinsing opening design is more conducive to water pressure concentration compared to the round nozzle design of ordinary enema tubes.

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] like Figures 1 to 4 As shown, this utility model claims protection for a visual enema device, including an enema inner tube 1. The enema inner tube 1 includes a silicone flexible tube segment 101 and a silicone rigid tube segment 102 connected together. The silicone flexible tube segment 101 is located at the front end and is mainly used for insertion into the anus and intestines, which can reduce damage to the intestinal mucosa. The silicone flexible tube segment 101 also provides support. The end of the silicone flexible tube segment 101 is provided with a fish-mouth arc-shaped flushing opening 2, and drainage openings 3 are symmetrically opened on both sides. The silicone rigid tube segment 102 is provided with a drainage interface 5 on the outside, which is connected to a drainage tube 6. The drainage interface 5 is connected to one end of the drainage tube 6 by thread or snap-fit, and the other end of the drainage tube 6 is connected to an enema fluid storage bag 7.

[0029] After the silicone tubing segment 101 is inserted into the anus and intestines, the enema fluid in the enema fluid storage bag 7 is sequentially injected into the anus and intestines through the drainage tube 6 and the enema internal cannula 1.

[0030] In this embodiment, the outer diameter of the rigid silicone tube segment 102 is 0.8±0.1cm, the wall thickness is 0.1±0.02cm, and its hardness is Shore A type 70-80 degrees, which is relatively good. The hardness of the flexible silicone tube segment 101 is Shore A type 30-40 degrees, which is relatively soft. Furthermore, from... Figure 1 It can be seen that the silicone tubing segment 101 is designed to gradually narrow towards the fish-mouth arc-shaped rinsing opening 2, which helps to smoothly insert it into the anus and intestines.

[0031] The fish-mouth arc flushing opening design, compared to the ordinary round nozzle design of enema tubes, is conducive to the concentration of water pressure and improves flushing force.

[0032] In this embodiment, the length of the silicone rigid tube segment 102 is 20±2cm, the length of the silicone flexible tube segment 101 is 5±1cm, and the axial distance from the center of the drainage interface 5 to the end of the fish-mouth arc irrigation opening 2 is 15±1cm. Since the insertion depth of the anal tube in clinical practice is usually less than 15cm, the maximum insertion depth is reached when the enema intubation cannula 1 is inserted close to the drainage interface 5, which also serves as a reference position.

[0033] The design of this utility model also includes a visualization component 4, which includes a gripping part 401, a flexible optical fiber 402, and a camera module 403. One end of the flexible optical fiber 402 is connected to the gripping part 401, and the other end extends to the silicone tubing section 101 and is fixedly connected to the camera module 403. The camera module 403 is a medical endoscope camera. The camera module 403 is connected to the display screen 406 in real time through the flexible optical fiber 402, and its lens is close to the fish mouth arc flushing opening 2 for easy observation. Therefore, the camera module 403 can transmit the collected images to the display screen 406 for display, improving the basis of operation.

[0034] When the visualization component 4 is inserted into the enema inner tube 1, the camera module 403 at the head end will be pushed to a position close to the fish mouth arc flushing opening 2. At this time, because the fish mouth is arc-shaped, there may be liquid inside the enema inner tube 1, and there may be liquid adhering to the front of the camera module 403. Therefore, by setting the drainage opening 3, it is beneficial for the enema liquid to be discharged from the side, providing an additional drainage path and helping to reduce obstruction.

[0035] like Figure 2 as well as Figure 3 See, the drainage interface 5 is provided with an annular valve assembly on the side away from the drainage opening 3. The annular valve assembly is composed of several circumferentially distributed elastic silicone sheets 8. The center formed by the several elastic silicone sheets 8 allows the flexible optical fiber 402 to pass through. The elastic silicone sheets 8 have a certain blocking effect on the flushing liquid to prevent backflow.

[0036] The front end of the gripping part 401 is also provided with a sleeve 404, and the front end of the sleeve 404 is provided with a clamping plate 405 fixed on the flexible optical fiber 402; the enema internal sleeve 1 is provided with a trumpet-shaped opening 103, and a limiting part 104 is provided on the inner side of the trumpet-shaped opening 103; the limiting part 104 is annular, and both the limiting part 104 and the clamping plate 405 are made of silicone material, which can undergo a certain degree of deformation. Therefore, when the visualization component 4 is assembled with the enema internal sleeve 1, pushing forward forcefully will push the clamping plate 405 into and through the annular hollow of the limiting part 104, forming a shape like... Figure 1 As shown in the diagram; when the visualization component 4 is assembled with the enema inner sleeve 1, the sleeve 404 is located inside the trumpet-shaped opening 103, and the clamping plate 405 is located on the side of the limiting part 104 near the fish mouth arc flushing opening 2, and the limiting part 104 prevents the visualization component 4 from detaching.

[0037] This invention relates to a visualization enema device. By incorporating visualization components, the insertion process can be visualized, thus avoiding the risk of perforation caused by enema due to variations in rectal structure and length. Furthermore, the intestinal condition can be reassessed through the photographed images after enema cleaning.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
