Description

Technical Field

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

[0002] In clinical diagnosis and treatment of anorectal diseases, bowel cleansing enemas, and enteral drug administration, the insertion process of traditional enema devices is rather abrupt. During insertion, the perianal sphincter is easily stimulated to contract and tighten, resulting in high insertion resistance, strong pain for the patient, and a high likelihood of difficulty in insertion. During anal dilation, rigid structures are often used, which can easily cause compression and abrasion to the perianal mucosa, resulting in low safety. Some pneumatic anal dilation structures can only achieve a single expansion and dilation function, and cannot simultaneously complete the perianal relaxation, resulting in limited functionality and insufficient adaptability. Moreover, conventional enema instruments lack a real-time observation field of the intestinal tract, making it impossible to intuitively determine the insertion position and intestinal condition. In addition, conventional enema equipment lacks a strict anti-backflow structure, making it easy for intestinal contents to reflux and contaminate the tubing. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this invention provides a visual enema device that integrates the functions of visual observation of the intestine, painless anal dilation with flexible air pressure, non-invasive relaxation of the perianal sphincter with airflow, anti-reflux drug infusion and water rinsing, thereby reducing catheterization injury and improving the comfort and ease of operation of diagnosis and treatment.

[0004] The technical solution adopted in this invention is as follows: A visual enema device includes a tubular body, an external pressure component and a vibration damping component. The external pressure component is sleeved on the rear end of the tubular body, and the vibration damping component is sleeved on the front end of the tubular body. The output end of the external pressure component is detachably and continuously connected to the vibration damping component. The vibration damping component includes a sealed elastic air chamber, an arc-shaped plate, an elastic connector, an elastic support pad, a silicone ring, and an elastic enclosure. The sealed elastic air chamber is annularly sleeved at the front end of the tubular main body. Multiple sets of arc-shaped plates and elastic connectors are arranged in annular staggered pattern. The arc-shaped plates are fixed to the circumferential sidewalls of the sealed elastic air chamber. The elastic connectors are located between adjacent arc-shaped plates. The elastic support pads are assembled on the outside of the elastic connectors. The silicone rings are sleeved on the outside of the elastic support pads, and the elastic support pads support the silicone rings. A space is reserved between the silicone rings and the arc-shaped plates. The elastic enclosure is fixed to the end of the annular structure composed of multiple sets of arc-shaped plates. The sealed elastic air cavity, arc plate, elastic connector, elastic support pad, and silicone ring are coaxially nested.

[0005] The sealed elastic air chamber has a first air outlet at its rear end. The first air outlet is connected to the chamber inside the sealed elastic air chamber. A control valve is installed in the first air outlet. When the control valve is opened, the gas in the sealed elastic air chamber can be discharged from the first air outlet.

[0006] Each of the arc-shaped plates has a gas storage chamber, and the rear end face of the arc-shaped plate has a first air inlet pipe and a second air inlet pipe. The first air inlet pipe is connected to the gas storage chamber, and the second air inlet pipe is connected to the sealed elastic gas chamber. Both the first air inlet pipe and the second air inlet pipe are equipped with control valves.

[0007] The arc-shaped plate has multiple sets of inclined air holes on its circumferential sidewall. The air holes are connected to the gas storage cavity. A fixing seat is installed on the circumferential sidewall of the arc-shaped plate. A vibrating plate is embedded in the fixing seat. The other end of the vibrating plate is a free end, which is located near the inner sidewall of the silicone ring. The vibrating plate is inclined at the upper end of the air hole. The gas blown out of the air hole blows the vibrating plate.

[0008] The silicone ring and the front end of the tubular body are equipped with a silicone sealing member. When the front end of the tubular body is slowly inserted into the intestine, the silicone sealing member will buffer the tubular body and slowly move the silicone ring to the anus.

[0009] The elastic enclosure is located on the rear end face of the arc-shaped plate and has a hollow internal structure. The first air inlet opening and the second air inlet opening on the arc-shaped plate are both located inside the elastic enclosure.

[0010] The external pressurization assembly includes a fixed plate and a sliding plate. The fixed plate is detachably fixed to the rear end of the tubular body, and the sliding plate is movably sleeved on the tubular body. An elastic element is installed between the fixed plate and the sliding plate. The elastic element is a hollow annular structure and is sleeved on the outside of the tubular body. A vent hose is installed on the side wall of the sliding plate. The two ends of the vent hose are respectively connected to the elastic element and the elastic enclosure. A second vent hole is also provided on the side wall of the sliding plate, and a control valve is installed in the second vent hole.

[0011] The tubular body has a transparent silicone ball head at its front end, which integrates a miniature camera and an ultraviolet LED cold light source. From front to back, the tubular body has a capillary water injection hole, a reverse-proof one-way injection port, and an inflation channel. An airbag is installed at the front end of the tubular body, and a sealed elastic air chamber is movably fitted onto the outside of the airbag. The inflation channel connects to the airbag, which has a corrugated structure. At the rear end of the tubular body, there is an injection channel inlet, a water interface, a video interface, and an inflation channel interface. The injection channel inlet is a Luer connector connected to the reverse-proof one-way injection port. The water interface connects to the capillary water injection hole. The video interface can connect to an external display. The miniature camera is electrically connected to an external display via the video interface. The power supply line for the ultraviolet LED cold light source is integrated inside the tubular body and extends to the rear end interface.

[0012] The anti-reverse one-way infusion port is a one-way valve structure that prevents intestinal fluid from flowing back into the tubular body. The Luer connector can be quickly connected to a syringe or infusion tubing to introduce infusion fluid. The tubular body is a flexible tubular structure made of medical-grade silicone or PVC, with a diameter of 1.5-2.0 cm, smaller than that of a conventional anoscope. Its front end, transparent silicone bulb, air bladder, and rear end interfaces are all integrally molded. The ultraviolet LED cold light source has a wavelength of 365-400nm, a safe near-ultraviolet band. The light is diffused and softened by the transparent silicone bulb, mainly used for fluorescence imaging of intestinal secretions and lesions to aid in identification. It also provides a gentle antibacterial effect on the body surface. The low-energy design will not cause burns or organic damage to the delicate intestinal mucosa. The miniature camera is a high-definition miniature camera that can collect images of the inside of the intestine in real time and transmit them to the external display.

[0013] The beneficial effects of the present invention after adopting the above structure are as follows: 1. An independent air supply path is used to direct the airflow through the inclined air hole to the silicone vibrating pad, forming a low-frequency gentle micro-vibration. The micro-vibration is transmitted to the perianal skin, effectively relieving the tight anal sphincter, reducing the resistance of insertion, and reducing the patient's resistance and pain from a physiological perspective.

[0014] 2. By using air pressure to drive the sealed elastic air chamber to achieve multi-stage radial expansion, the silicone ring slowly completes the flexible expansion of the anus, abandoning the traditional rigid stretching method. The expansion force is gentle and uniform, effectively avoiding the squeezing and abrasion of the perianal mucosa, and greatly improving the comfort of diagnosis and treatment.

[0015] 3. The vibration damping component is movably attached to the outside of the tubular body. Relying on the resistance of the anal soft tissue to offset the axial friction force generated by the inner side of the sealed elastic air chamber after inflation, the vibration damping component can be stably retained in the anal position when the tubular body is pushed at a uniform speed. It will not follow the tube into the intestine, thus accurately separating the insertion and perianal positioning operations.

[0016] 4. It integrates multiple functions such as high-definition visual camera observation, one-way anti-reverse drug infusion, independent water flushing, and intestinal wall corrugated airbag sealing and anti-slip. The multi-channel interface layout is well-organized, and the Luer connector can quickly connect to external drug delivery devices, completing multiple diagnosis and treatment operations in one stop and simplifying the operation process. It is equipped with an anti-reverse one-way infusion port, which can completely block the backflow of intestinal liquids and waste into the tubular body, avoid pipeline contamination, and ensure the cleanliness of enema drug delivery.

[0017] 5. The rear external inflation component relies on the sliding plate to squeeze the hollow elastic element to achieve manual air supply. There is no need to connect a large external inflation device. Multiple control valves can freely switch between various working states such as inflation expansion, airflow vibration, and depressurization and retraction. Pressure regulation and air control are simple and easy to use. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0023] In this embodiment, refer to Figure 1 A visual enema device includes a tubular body 1, an external pressure component 2, and a vibration damping component 3. The external pressure component 2 is sleeved at the rear end of the tubular body 1, and the vibration damping component 3 is sleeved at the front end of the tubular body 1. The output end of the external pressure component 2 is detachably and continuously connected to the vibration damping component 3.

[0024] In this embodiment, refer to Figure 5 , Figure 6 and Figure 7The vibration damping component 3 includes a sealed elastic air chamber 4, an arc-shaped plate 5, an elastic connector 6, an elastic support pad 7, a silicone ring 8, and an elastic barrier 9. The sealed elastic air chamber 4 is annularly sleeved at the front end of the tubular body 1. Multiple sets of arc-shaped plates 5 and elastic connectors 6 are arranged in annular staggered pattern. The arc-shaped plates 5 are fixed to the circumferential sidewalls of the sealed elastic air chamber 4. The elastic connectors 6 are located between adjacent arc-shaped plates 5. The elastic support pad 7 is assembled on the outside of the elastic connector 6. The silicone ring 8 is sleeved on the outside of the elastic support pad 7, supporting the silicone ring 8. A space is reserved between the silicone ring 8 and the arc-shaped plate 5. The elastic barrier 9 is fixed to the end of the annular structure composed of multiple sets of arc-shaped plates 5. The sealed elastic air chamber 4, arc-shaped plate 5, elastic connector 6, elastic support pad 7, and silicone ring 8 are coaxially nested.

[0025] After the sealed elastic air cavity 4 is slowly ventilated, it gradually expands radially outward, driving the arc plate 5 and the elastic connector 6. The elastic connector 6 expands radially outward, driving the elastic support pad 7. The elastic support pad 7 slowly drives the silicone ring 8, and the silicone ring 8 expands radially outward to flexibly expand the anus.

[0026] In this embodiment, refer to Figure 6 and Figure 7 The sealed elastic air chamber 4 has a first air outlet 16 at its rear end, which is connected to the chamber inside the sealed elastic air chamber 4. A control valve is installed in the first air outlet 16. When the control valve is opened, the gas in the sealed elastic air chamber 4 can be discharged from the first air outlet 16. Each set of arc-shaped plates 5 has a gas storage chamber 13. The rear end face of the arc-shaped plate 5 has a first air inlet pipe 14 and a second air inlet pipe 15. The first air inlet pipe 14 is connected to the gas storage chamber 13, and the second air inlet pipe 15 is connected to the sealed elastic air chamber 4. A control valve is installed in both the first air inlet pipe 14 and the second air inlet pipe 15. The elastic enclosure 9 is located on the rear end face of the arc-shaped plate 5 and has a hollow internal structure. The openings of the first air inlet pipe 14 and the second air inlet pipe 15 on the arc-shaped plate 5 are both located in the elastic enclosure 9. Specifically, when the control valve in the first intake pipe 14 is closed and the control valve in the second intake pipe 15 is open, the gas enters the sealed elastic gas chamber 4 through the second intake pipe 15. At this time, the control valve in the first outlet 16 is closed, and the sealed elastic gas chamber 4 expands slowly. When the control valve in the first intake pipe 14 is open and the control valve in the second intake pipe 15 is closed, the gas enters the gas storage chamber 13 through the first intake pipe 14 and is discharged from the blowing hole 10.

[0027] In this embodiment, refer to Figure 6 and Figure 7The arc-shaped plate 5 has multiple sets of inclined air holes 10 on its circumferential sidewall. The air holes 10 are connected to the gas storage chamber 13. A fixing seat 11 is installed on the circumferential sidewall of the arc-shaped plate 5. A vibrating plate 12 is embedded in the fixing seat 11. The other end of the vibrating plate 12 is a free end, which is located close to the inner sidewall of the silicone ring 8. The vibrating plate 12 is inclined above the air holes 10. The gas blown out of the air holes 10 blows the vibrating plate 12. The free end of the vibrating plate 12 is far from the silicone ring 8. The inner wall is about 0.5-1mm thick, which ensures that it can slightly touch the skin during vibration without damaging the tissue. The airflow blows from the oblique air hole 10 of the arc plate 5 at an angle of 30°-45° onto the plane of the vibrating plate 12. The vibrating plate 12 is driven by a constant airflow to produce gentle low-frequency micro-vibrations. The vibration is transmitted to the silicone ring 8, and the outer surface of the silicone ring 8 vibrates, thus acting on the perianal skin and relaxing the sphincter muscles. The vibrating plate 12 is made of ultra-soft medical silicone with a Shore angle of 10-15°. It is thin and elastic and is easily blown by the airflow to vibrate back and forth.

[0028] In this embodiment, refer to Figure 4 and Figure 5 The silicone ring 8 and the front end of the tubular body 1 are equipped with a silicone sealing member 17. When the front end of the tubular body 1 is slowly inserted into the intestine, the tubular body 1 can slowly move the silicone ring 8 to the anus position under the buffering effect of the silicone sealing member 17.

[0029] In this embodiment, refer to Figure 2 , Figure 5 and Figure 9 The external pressurization assembly 2 includes a fixed plate 18 and a sliding plate 19. The fixed plate 18 is detachably fixed to the rear end of the tubular body 1. The sliding plate 19 is movably sleeved on the tubular body 1. An elastic element 20 is installed between the fixed plate 18 and the sliding plate 19. The elastic element 20 is a hollow annular structure. The elastic element 20 is sleeved on the outside of the tubular body 1. A ventilation hose 27 is installed on the side wall of the sliding plate 19. The two ends of the ventilation hose 27 are respectively connected to the elastic element 20 and the elastic enclosure 9. A second vent hole 21 is also provided on the side wall of the sliding plate 19. A control valve is provided in the second vent hole 21. Specifically, when the control valve inside the second air outlet 21 is closed, and the operator gently pushes the tubular body 1 into the intestine, the tubular body 1 slowly moves the silicone ring 8 to the anus under the buffering effect of the silicone sealing component 17. Then, the inflation channel inflates the airbag 28, and the airbag 28 slowly inflates, driving the vibration damping component 3. The vibration damping component 3 gradually expands, and after the sealed elastic air chamber 4 is slightly higher than the circumferential sidewall of the tubular body 1, the inflation inside the airbag 28 stops. Then, the operator holds the sliding plate 19 and moves it closer to the anus. The fixed plate 18 is slowly pushed in the direction of the sliding plate 19, which slowly compresses the elastic element 20. The gas inside the elastic element 20 enters the elastic enclosure 9 through the ventilation hose 27. At this time, the control valves in the first air inlet pipe 14 and the first air outlet 16 are closed, and the control valve in the second air inlet pipe 15 is opened. The gas enters the sealed elastic air chamber 4 through the second air inlet pipe 15. The sealed elastic air chamber 4 slowly expands, driving the arc plate 5 and the elastic connecting member 6. The elastic connecting member 6 expands radially outward, driving the elastic support pad 7. The support pad 7 slowly drives the silicone ring 8, causing the silicone ring 8 to expand radially outwards, flexibly dilating the anus. Then, the control valve in the first air inlet pipe 14 is opened, and the control valve in the second air inlet pipe 15 is closed. Gas enters the gas storage chamber 13 through the first air inlet pipe 14 and is discharged from the air outlet 10, blowing onto the plane of the vibrating plate 12. The vibrating plate 12 is driven by a constant airflow, generating gentle low-frequency micro-vibrations that directly act on the perianal skin, relaxing the sphincter muscles. Then, the tubular body 1 is slowly inserted, and the tubular body 1 is pushed in at a uniform and slow speed. During operation, the axial clamping resistance formed by the soft tissue of the anus against the silicone ring 8 is greater than the gripping friction between the inner side of the sealed elastic air chamber 4 and the tubular body 1. Therefore, the vibration damping component 3 can remain stably in the anal position and will not enter the intestine along with the tubular body 1. As the body gradually relaxes, the control valves in the first air outlet 16 and the second air outlet 21 are opened, the gas in the sealed elastic air chamber 4 is slowly discharged, the silicone ring 8 gradually retracts, reducing the impact on the anus, and then the vibration damping component 3 is manually removed from the anus.

[0030] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 and Figure 8The tubular body 1 has a transparent silicone ball head 22 at its front end, which integrates a miniature camera 23 and an ultraviolet LED cold light source 24. The surface of the transparent silicone ball head 22 has a superhydrophobic coating to prevent dirt adhesion. The tubular body 1 has a capillary water injection hole 25, a reverse-proof one-way injection port 26, and an inflation channel from front to back. An airbag 28 is installed at the front end of the tubular body 1. The sealed elastic air chamber 4 is movably sleeved on the outside of the airbag 28. The inflation channel connects to the airbag 28. The airbag 28 has a corrugated structure. The rear end of 1 is provided with an infusion channel inlet, a clean water interface, a video interface, and an inflation channel interface. The infusion channel inlet is a Luer connector connected to the anti-reverse one-way infusion port 26. The clean water interface is connected to the capillary clean water injection hole 25. The video interface can be connected to an external display. The miniature camera 23 is electrically connected to the external display through the video interface. The power supply line of the ultraviolet LED cold light source 24 is integrated inside the tubular body 1 and extends to the rear end interface. After inflation, the airbag 28 expands in a corrugated shape to increase the contact area with the intestinal wall to achieve sealing, leak prevention, and anti-slip functions.

[0031] The anti-reverse one-way infusion port 26 has a one-way valve structure to prevent intestinal fluid from flowing back into the tubular body 1; the Luer connector can be quickly connected to a syringe or infusion tubing to introduce infusion fluid; the tubular body 1 is a flexible tubular structure made of medical-grade silicone or PVC, with a diameter of 1.5-2.0 cm, smaller than the diameter of a conventional anoscope; its front end, the transparent silicone bulb head 22, the air bladder 28, and the various interfaces at the rear end are integrally molded; the ultraviolet LED cold light source 24 has a wavelength of 365-400nm, a safe near-ultraviolet band, and is diffused and softened by the transparent silicone bulb head, mainly used for auxiliary identification of intestinal secretions and lesions through fluorescence imaging, while achieving a gentle antibacterial effect on the body surface; the low-energy design will not cause burns or organic damage to the delicate intestinal mucosa; the miniature camera 23 is a high-definition miniature camera that can collect images of the inside of the intestine in real time and transmit them to the external display.

[0032] The airbag 28, silicone ring 8, and silicone sealing component 17 are made of medical-grade silicone. Before inflation, the airbag 28 is attached to the outer surface of the tubular body 1. After inflation, it can expand evenly to fit the intestinal wall of different diameters.

[0033] The specific implementation and usage methods are as follows: Beforehand, check that all control valves of the device are closed, and confirm that the wiring of the miniature camera 23 and the ultraviolet LED cold light source 24 is normal. Connect the rear water interface, the inlet of the injection channel, and the video interface to the corresponding external devices. Apply medical lubricant only to the human contact parts on the outside of the device, and do not lubricate the internal mating surfaces.

[0034] Holding the rear end of the tubular main body 1, the front transparent silicone ball head 22 is aligned with the anus and slowly inserted into the intestine. Under the buffering and limiting effect of the silicone sealing component 17, the outer vibration damping component 3 is driven to move smoothly to the designated position of the anus and then the push is stopped, completing the initial positioning of the component.

[0035] Inflation is introduced into the front corrugated airbag 28 through the inflation channel interface at the rear end of the tubular body 1. The airbag 28 slowly inflates, driving the vibration damping component 3. The vibration damping component 3 gradually expands, and after the sealed elastic air chamber 4 is slightly higher than the circumferential side wall of the tubular body 1, the inflation inside the airbag 28 stops.

[0036] Open the control valve of the second air inlet pipe 15, and medical staff hold the sliding plate 19 of the external inflation component 2 and slowly squeeze it towards the fixed plate 18 to compress the hollow annular elastic element 20. The internal gas is introduced into the cavity of the elastic enclosure 9 through the ventilation hose 27, and then into the sealed elastic air chamber 4 through the second air inlet pipe 15. After the sealed elastic air chamber 4 is inflated, it deforms and expands radially on the outside, pushing the arc plate 5, the elastic connector 6, and the elastic support pad 7 in sequence, and finally driving the silicone ring 8 to slowly expand outward, completing the flexible non-invasive expansion of the anus.

[0037] After the anus is dilated to the appropriate size, switch the air circuit control state, close the control valve of the second air inlet pipe 15, and simultaneously open the control valve of the first air inlet pipe 14. Airflow enters the gas storage chamber 13 inside the arc-shaped plate 5 through the first air inlet pipe 14, and then blows out directionally from the air blowing hole 10 at an angle of 30°-45°, continuously blowing the ultra-soft silicone vibrating plate 12 above, causing it to generate low-frequency gentle micro-vibrations. The vibration is transmitted to the silicone ring 8, and the outer surface of the silicone ring 8 vibrates, thereby acting on the perianal skin and relaxing the sphincter muscles.

[0038] After the perianal muscles are fully relaxed, keep the vibration damping component 3 stationary on the outside of the anus, and slowly push the tubular body 1 forward into the intestine at a uniform speed. Relying on the axial clamping resistance of the anus against the silicone ring 8, the clamping friction between the sealed elastic air chamber 4 and the tubular body 1 is offset, ensuring that the component does not shift. As the body gradually relaxes, the control valves in the first air outlet 16 and the second air outlet 21 are opened, the gas in the sealed elastic air chamber 4 is slowly discharged, the silicone ring 8 gradually retracts, reducing the impact on the anus, and then the vibration damping component 3 is manually removed from the anus.

[0039] Inflation is performed through the rear air channel interface of the tubular main body 1 to the front corrugated structure airbag 28. After inflation, the airbag 28 expands uniformly along the axial and radial directions, closely adhering to the intestinal wall. Inflation is stopped after the airbag 28 reaches the adhering state. Subsequently, the drug solution is injected unidirectionally through the Luer connector type infusion channel inlet. At the same time, the miniature camera 23 and the ultraviolet LED cold light source 24 are turned on to observe the intestinal condition in real time. If the transparent silicone ball head 22 is covered with dirt and the field of vision is blurred, it is flushed through the capillary water injection hole 25.

[0040] After the enema and intestinal diagnosis and treatment are completed, the gas in the balloon 28 is expelled, and then the tubular main body 1 is slowly pulled out to complete all diagnosis and treatment procedures.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents. In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the invention, such designs should fall within the protection scope of the present invention.
