Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an ozone water flushing device for the treatment of perianal diseases. Background Technology

[0002] Ozone water has broad-spectrum bactericidal properties and does not induce drug resistance, and it has been used for irrigation treatment in anorectal departments. During the treatment of perianal diseases or postoperative care, the irrigation solution needs to reach irregular areas such as wounds, cavities, sinuses, or blind tubes to remove secretions, necrotic tissue, or residual contaminants, and help reduce the risk of local infection.

[0003] Existing irrigation devices mostly use standard straight or open-ended designs, lacking specialized irrigation heads for deep cavities, sinus tracts, and blind tubes in the perianal region. In clinical practice, doctors often need to repeatedly adjust the angle or use self-made extension tubes for irrigation, which is not only inconvenient but also makes it difficult to ensure that the irrigation fluid accurately reaches hidden areas, easily leaving irrigation dead zones and affecting the removal of secretions, necrotic tissue, or residual contaminants. Therefore, there is a need for an irrigation device that can stably prepare and deliver ozone water, adjust the water outlet direction of the irrigation tube head, and switch the water outlet mode according to the spatial morphology of the lesion.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, embodiments of the present invention; 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.

[0021] In the description of this invention, the term "and / or" is used to indicate that associated objects can exist individually or simultaneously; the terms "first," "second," etc., are used only to distinguish identical or similar components and do not indicate order, quantity, or importance. The terms "connection," "connection," "installation," "setting," etc., should be interpreted broadly and can refer to direct connection, indirect connection, fixed connection, detachable connection, movable connection, or fluid communication, unless the context explicitly defines otherwise.

[0022] Example 1 like Figures 1 to 9 As shown, this embodiment provides an ozone water flushing device for treating perianal diseases, including an ozone water generating unit 1 and a flushing unit 2 connected to the ozone water generating unit 1. The ozone water generating unit 1 is used to generate ozone water within the device body and output it externally. The flushing unit 2 is used by the operator to hold and guide the ozone water to the perianal area to be flushed. The flushing unit 2 includes a handle 23, an adjustment component 22, a flushing nozzle 21, and a locking component 24. The handle 23 is connected to the output end of the ozone water generating unit 1. The handle 23 is a hollow tube, and a connecting pipe 25 is provided inside the handle 23. The adjustment component 22 is arranged between the distal end of the handle 23 and the proximal end of the flushing nozzle 21, so that the flushing nozzle 21 can maintain fluid communication with the connecting pipe 25 and can be angularly adjusted relative to the handle 23.

[0023] In this embodiment, the handheld part 23 can form a composite structure that serves as both a gripper and an internal water channel support. Its internal cavity accommodates the connecting pipe 25, and its outer surface provides a stable grip for the operator. One end of the handheld part 23 near the ozone water generating unit 1 is connected to the delivery pipe 17, and the other end near the rinsing head 21 is arranged adjacent to the adjustment assembly 22. This arrangement allows the operator to directly control the entry direction and depth of the rinsing head 21 while gripping the handheld part 23, while preventing the operator from directly contacting the distal area of ​​the rinsing head 21.

[0024] When the connecting ball head 222 is fixedly installed or integrally formed with the flushing tube head 21, the connecting ball head 222 can serve as a fulcrum for rotation of the flushing tube head 21, and the locking claws 221 are arranged in a circumferential array around the outside of the connecting ball head 222. The receiving space formed between the multiple locking claws 221 is adapted to the outer surface of the connecting ball head 222, so that the connecting ball head 222 can rotate relative to the locking claws 221 in the unlocked state, and is clamped and positioned by the locking claws 221 in the locked state. Through this spherical mating relationship, the flushing tube head 21 can change its pitch or yaw direction relative to the handle 23, thereby adapting to situations where the perianal lesion is irregularly located, the sinus tract is curved, or the blind tube entrance is deviated.

[0025] During use, ozone water enters the flushing unit 2 from the ozone water generating unit 1, passes through the handheld part 23 into the connecting pipe 25, and then exits through the connecting pipe 25 and the flushing head 21 for perianal flushing. When the angle of the flushing head 21 needs to be adjusted, the locking component 24 is depressurized or the pressure on the locking claw 221 is reduced. At this time, the connecting ball head 222 can be moved within the receiving space, causing the flushing head 21 to change its angle relative to the handheld part 23. After the angle adjustment is completed, the locking component 24 continues to provide pressure to the locking claw 221 so that the locking claw 221 clamps the connecting ball head 222, thereby keeping the connecting ball head 222 and the flushing head 21 in a fixed and stable state. The connecting pipe 25 can remain connected within the connecting ball head 222 and adapts to the angle adjustment action of the connecting ball head 222 through its own flexibility or the sealing fit with the connecting ball head 222 to ensure that the water path is not cut off during the angle adjustment process.

[0026] The connecting pipe 25 passes through the connecting ball head 222 and extends into the flushing pipe head 21, ensuring the ozone water flow remains continuous after crossing the adjusting component 22. A tight fit, a sealing ring fit, or a flexible pipe section fit can be used between the connecting pipe 25 and the connecting ball head 222 to reduce the possibility of leakage at the water connection point during angle adjustment. Since the connecting pipe 25 is located inside the handle 23, the external operating force is mainly borne by the handle 23 and the adjusting component 22. The connecting pipe 25 primarily performs the function of fluid delivery, thereby improving the overall stability of the flushing unit 2.

[0027] Furthermore, the locking assembly 24 includes a sleeve 241, a locking portion 242, a protrusion 243, a limiting seat 244, a first spring 245, and a receiving cavity 246. This locking assembly 24 applies pressure to the locking claw 221 in the locked state and releases the locking claw 221 in the unlocked state, allowing the connecting ball head 222 to rotate. The locking assembly 24, in conjunction with the adjusting assembly 22, forms a continuous action relationship of manual angle adjustment, elastic reset, and clamping positioning, thereby enabling the operator to adjust the direction of the flushing head 21 within a small operating space.

[0028] The receiving cavity 246 is cylindrical and is disposed on the handle 23. The sleeve 241 is fixedly connected to the locking part 242, which has a cup-shaped structure and matches the locking claw 221. When the locking part 242 approaches the locking claw 221, it can apply radial or oblique pressure to the locking claw 221, which has multiple elastic plate structures. The limiting seat 244 is fixedly connected to the sleeve 241. The first spring 245 is sleeved on the handle 23 and located within the receiving cavity 246. The limiting seat 244 is also located within the receiving cavity 246 and is used to prevent the sleeve 241 from disengaging from the receiving cavity 246. The protrusion 243 is located on the sleeve 241 and is exposed in a position accessible to the operator.

[0029] When the locking part 242 is configured as a bowl-shaped structure, its inner surface can contact the outer surfaces of the multiple locking claws 221. Under the restoring force of the first spring 245, the sleeve 241 drives the locking part 242 to approach the locking claws 221, and the locking part 242 presses the locking claws 221 towards the connecting ball head 222, thereby forming a circumferential clamping of the connecting ball head 222. Compared with the single-point screw clamping method, the circumferential clamping of multiple locking claws 221 can make the connecting ball head 222 more evenly stressed, reducing the shaking of the flushing tube head 21 under the reaction force of the flushing water flow or the resistance of the contact tissue.

[0030] During use, by moving the protrusion 243, the sleeve 241 can slide on the handle 23. When the sleeve 241 slides into the receiving cavity 246, it moves the locking part 242 away from the locking claw 221. At this time, the first spring 245 is compressed, and the locking part 242 cancels or reduces the locking pressure on the locking claw 221, allowing the operator to rotate the connecting ball head 222. After rotating to the desired angle, the force applied to the protrusion 243 is released, the first spring 245 pushes the sleeve 241 back to its original position, and the sleeve 241 continues to apply pressure to the locking claw 221, causing the locking claw 221 to lock the connecting ball head 222. Thus, the flushing head 21 can be adjusted in angle before or during use, and can remain stable after adjustment, facilitating directional flushing of deep cavities, sinuses, or blind tubes.

[0031] Furthermore, in this embodiment, a switching assembly 26 is also provided inside the flushing head 21. The front end of the flushing head 21 forms a front outlet, and the side wall of the flushing head 21 has water outlet holes 211, which are arranged equidistantly around the side wall of the flushing head 21. The switching assembly 26 includes a second spring 261, a switching block 262, a driving member 263, two connecting rods 264, and a rotating sleeve 265. The inner wall of the flushing head 21 is provided with a support edge 212. The second spring 261 is installed inside the flushing head 21 and contacts or connects with the support edge 212. The inner wall of the flushing head 21 is also provided with a strip-shaped protrusion 213. The switching block 262 is slidably connected to the strip-shaped protrusion 213, so that the switching block 262 can move along the axial direction of the flushing head 21 without easily deflecting circumferentially. The switching block 262 has a central hole for water supply. Even when the outlet hole 211 is closed, the ozone water can still flow through this hole to the front outlet of the flushing pipe head 21.

[0032] The sliding connection between the switching block 262 and the strip protrusion 213 also limits the movement trajectory of the switching block 262, allowing it to move axially along the flushing head 21 when the water outlet 211 is opened or closed. The support edge 212 provides a support position for the second spring 261, which in turn provides an elastic force to the switching block 262, ensuring that the switching block 262 can stably enter the corresponding position after the drive member 263 rotates. Thus, the external rotation of the rotating sleeve 265 is converted into axial displacement of the switching block 262 inside the flushing head 21, facilitating the switching of the water outlet mode without disassembling the flushing head 21.

[0033] When the drive unit 263 is in the first position, the switching block 262 blocks the water outlet 211. The ozone water continues to flow towards the front outlet of the flushing head 21 mainly through the central hole of the switching block 262, forming an axial flush. The axial flushing state is suitable for flushing shallower areas, straight sinus tract entrances, or areas where secretions need to be flushed first. Because the water outlet 211 is blocked in this state, the lateral water flow is reduced, making it easier for the operator to control the water flow direction and reduce the overflow of flushing fluid in non-target directions.

[0034] When lateral or circumferential rinsing is required, the operator moves the rotating sleeve 265. The rotating sleeve 265 drives the drive component 263 to rotate via two connecting rods 264. The drive rod 2631 on the drive component 263 moves along the guide slope 2622 of the transmission part 2621. The guide slope 2622 converts the circumferential movement of the drive rod 2631 into an axial pushing or yielding action on the switching block 262. Under the elastic force of the second spring 261, the switching block 262 moves to a position where it no longer blocks the water outlet 211, and ozone water can be discharged from the water outlet 211 on the side wall of the rinsing pipe head 21.

[0035] Two arc-shaped notches 214 are provided on the flushing head 21. One end of two connecting rods 264 is fixedly connected to the drive component 263. The two connecting rods 264 extend from the arc-shaped notches 214 and are fixedly connected to the rotating sleeve 265. The rotating sleeve 265 is rotatably connected to the flushing head 21. The arc-shaped notches 214 provide circumferential swing space for the connecting rods 264, so that the rotating sleeve 265 can drive the drive component 263 to rotate synchronously when it is externally moved. The side wall of the drive component 263 fits tightly against the inner wall of the flushing head 21 to achieve sealing and prevent ozone water from being discharged through the arc-shaped notches 214. This fit also allows the ozone water to enter the vicinity of the switching block 262 along a predetermined water path, reducing unexpected leakage.

[0036] With the aforementioned switching component 26, the flushing head 21 can be switched between axial and lateral / circumferential water flow without replacement. Combined with the adjustment component 22 and locking component 24, the operator can first adjust the angle of the flushing head 21 and then select the opening state of the water outlet 211, thereby allowing ozone water to more accurately reach deep perianal cavities, sinus tracts, and blind tube areas, reducing flushing dead zones and improving the convenience of the flushing operation. In actual flushing, the operator can first use axial flushing to flush the inlet or main channel, and then switch to lateral / circumferential flushing to provide a comprehensive flushing of the cavity sidewalls. Alternatively, the operator can switch between the two water flow modes according to the wound location and the patient's tolerance.

[0037] The number of water outlets 211 is 2 to 8, with a diameter of 0.3 to 1.5 mm. The spray direction of each water outlet 211 forms different angles with the axis of the flushing head 21 from 30° to 150°, allowing the flushing head 21 to form multi-angle coverage in space. The setting of the orifice diameter range can ensure that the water flow has a certain flushing capacity while avoiding excessive flow velocity in a single orifice; the different spray angles can allow ozone water to cover the side walls of the sinus tract, the periphery of the blind cavity, and the edges of irregular wounds.

[0038] In another embodiment, the water outlets 211 are arranged in a spiral or layered manner in the circumferential direction, with a circumferential angle between adjacent water outlets 211 of 30° to 120° and an axial spacing of 2 to 10 mm. The number of holes, hole diameter, spray angle, circumferential angle, and axial spacing can be selected according to the size of the perianal cavity, sinus tract, or blind tube to balance the flushing coverage and patient tolerance. When the water outlets 211 are arranged in a spiral manner, the flushing head 21 can form a continuous sweeping water flow during slow advancement or withdrawal; when the water outlets 211 are arranged in a layered manner, water outlets 211 at different axial positions can form layered flushing of areas at different depths.

[0039] After the distal end of the flushing head 21 enters the sinus tract or cavity, the front outlet can flush the deep channel along the axial direction of the flushing head 21, while the side wall outlet 211 can provide transverse flushing to the side wall of the channel. When the front outlet and the side wall outlet 211 are used together, ozone water can simultaneously contact the area to be flushed in both longitudinal and transverse directions, which helps to reduce the risk of local omissions caused by ordinary straight-head flushing heads that can only spray in one direction.

[0040] Example 2 This embodiment further illustrates the structure of the ozone water generating unit 1 compared to Embodiment 1. The ozone water generating unit 1 includes a first housing 11, a second housing 12, a water tank 13, an ozone generator 14, a delivery pump 15, a flow regulating valve 16, a delivery pipe 17, and a heating device 18. The first housing 11 and the second housing 12 constitute an external support and protective structure. The water tank 13 is used to contain water to be ozonated. The ozone generator 14 is used to generate ozone and introduce it into the water tank 13. The delivery pump 15 is used to deliver the generated ozone water into the delivery pipe 17.

[0041] The first housing 11 and the second housing 12 are fastened together, forming an installation space between them. The water tank 13, the ozone generator 14, and the delivery pump 15 are all installed within this installation space. The main body of the ozone generator 14 is located within the installation space. The ozone output end of the ozone generator 14 or the aeration element connected to the ozone generator 14 is located at the bottom of the water tank 13. The ozone generator 14 is used to deliver ozone into the water tank 13 via the ozone output end or the aeration element. The ozone is delivered from the bottom of the water tank 13, which facilitates the ozone entering the water body from bottom to top and mixing thoroughly with the water, thereby forming ozone water with a relatively stable concentration. The input end of the delivery pump 15 is connected to the water tank 13, and the output end of the delivery pump 15 is connected to the delivery pipe 17. The delivery pipe 17 extends from the installation space and is connected to the handle 23. The flow regulating valve 16 and the heating device 18 are respectively installed on the delivery pipe 17.

[0042] When the first housing 11 and the second housing 12 are fastened together, they form a relatively enclosed installation space, which supports and protects the water tank 13, ozone generator 14, delivery pump 15, and electrical control components. The relative positions of the water tank 13, ozone generator 14, and delivery pump 15 within the installation space minimize the ozone water generation and output paths, thereby reducing water path bends and residual space. The delivery pipe 17 extends from the installation space and connects to the handheld part 23, establishing an operable external connection between the ozone water generation unit 1 and the rinsing unit 2.

[0043] During use, the delivery pump 15 delivers ozone water from the water tank 13 to the handheld unit 23 via the delivery pipe 17. The ozone water then enters the flushing head 21 via the connecting pipe 25 and is finally discharged from the flushing head 21 for perianal flushing. The flow regulating valve 16 is used to regulate the flow rate of ozone water in the delivery pipe 17, and the heating device 18 is used to heat the ozone water in or flowing through the delivery pipe 17 to make the flushing solution temperature suitable for clinical operation needs. Because the flow regulating valve 16 is located on the water delivery path, the operator can adjust the flushing intensity according to the depth of the lesion, the size of the cavity, and the patient's tolerance, avoiding insufficient cleaning due to too weak a water flow or discomfort due to too strong a water flow.

[0044] The device also includes a control panel 19, which is a touch panel with a built-in controller. A concentration sensor 171 is also installed on the delivery pipe 17. The controller is connected to the concentration sensor 171, the ozone generator 14, the heating device 18, and the flow regulating valve 16. Based on the concentration feedback from the concentration sensor 171, the controller adjusts the power or air intake of the ozone generator 14 to maintain the output ozone water concentration within a set range, for example, 3–6 mg / L. Simultaneously, the operator can adjust the flow rate and temperature via the control panel 19, and control the heating device 18 to heat or stop. Therefore, the device can centrally regulate the concentration, temperature, and flow rate during rinsing, reducing the instability of rinsing caused by fluctuations in ozone water parameters.

[0045] When the concentration sensor 171 is installed on the delivery pipe 17, its detection position is close to the output water path, allowing it to more directly reflect the concentration of ozone water about to enter the rinsing unit 2. The controller adjusts the power or air intake of the ozone generator 14 based on the detection value of the concentration sensor 171 to maintain the ozone water concentration within a set range. When the detection value is too low, the power or air intake of the ozone generator 14 can be increased; when the detection value is too high, the power or air intake of the ozone generator 14 can be decreased. This closed-loop regulation method helps reduce concentration fluctuations in ozone water caused by dissolution, dispersion, or flow rate changes during generation and delivery.

[0046] A single flushing operation may include the following steps: adding flushing water to the water tank 13 and starting the ozone generator 14 to generate ozone water; setting the ozone water concentration, flow rate, or temperature via the control panel 19; delivering the ozone water to the handheld part 23 via the delivery pump 15 and the delivery pipe 17; adjusting the angle of the flushing nozzle 21 by moving the protrusion 243 according to the location of the lesion; adjusting the rotating sleeve 265 as needed to select axial or lateral / circular water discharge; stopping the delivery pump 15 and cleaning or replacing the flushing nozzle 21 after flushing. The above process allows water production, delivery, angle adjustment, and water discharge mode switching to be continuously completed within the same device.

[0047] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors; any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
