Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an anal irrigator. Background Technology

[0002] Anal irrigators, commonly used in proctology within the field of medical device technology, are widely applied in postoperative care, daily perianal hygiene maintenance, and as an adjunct treatment for perianal diseases such as hemorrhoids and anal fissures. Their core function is to clean the perianal area and intestinal cavity by delivering irrigation fluid, reducing wound irritation, lowering the risk of infection, and improving patient comfort during postoperative recovery and the convenience of daily care. Currently, most anal irrigators on the market are based on a water storage container, connecting hose, and irrigation head. However, with the increasing sophistication of clinical nursing needs and patients' growing demands for safety, the industry is gradually raising technical requirements for anal irrigators in terms of pressure control precision, contamination prevention reliability, and adaptability to different wound surfaces, necessitating optimized designs that better suit actual clinical applications.

[0003] However, existing anal irrigators still have many technical shortcomings in practical applications, making it difficult to meet clinical needs: First, the irrigation pressure control is unstable. Most products rely on the user manually squeezing the water reservoir to adjust the pressure, which is prone to fluctuations in output water pressure due to uneven force. If the pressure is too low, it cannot clean the perianal folds or deep intestinal tract residues; if the pressure is too high, it may damage the fragile postoperative wound tissue. Furthermore, there is a lack of anti-leakage design, meaning that even slight contact with the water reservoir can cause leakage of the irrigation solution. Second, the backflow prevention and contamination prevention effects are poor. Existing products mostly use a single one-way valve to prevent sewage backflow, but... When the flushing pressure changes suddenly, tiny contaminants can easily backflow through the valve body gaps, contaminating the flushing fluid in the water storage container. If the flusher is reused, it may also cause cross-infection. At the same time, the one-way valve is prone to fatigue failure after long-term use, further reducing the reliability of contamination prevention. Thirdly, there is insufficient adaptability to different scenarios and insufficient splash prevention. Most existing flushing heads are of a fixed shape, which makes it difficult to fit closely to the perianal shape of different patients. During the flushing process, sewage containing contaminants can easily splash from the gaps in the fit, contaminating the operator's clothes, hands, or the bed environment. This problem is more prominent in the scenario of flushing patients in the lateral position of bedridden patients. Summary of the Invention

[0010] In a preferred embodiment of the anal irrigator of the present invention, an elastic check valve is further provided on the inner wall of the irrigation channel and the elastic check valve is located at the end of the float ball, and an isolation cavity is formed between the elastic check valve and the float ball.

[0011] In a preferred embodiment of the anal irrigator of the present invention, the outer wall of the rotating ring is provided with a first groove and a second groove, and the end of the first protruding rib located at the end of the mounting head extends to the inner wall of the first groove and slides therewith.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example

[0022] Reference Figures 1-4 This is the first embodiment of the present invention, which provides an anal irrigator.

[0023] Specifically, the main component 100 includes a water storage tank 101, a water storage cavity 1011 is provided inside the water storage tank 101, and an installation head 102 is fixed at the end of the water storage cavity 1011. A rotating ring 103 is provided inside the installation head 102, and a moving part is provided on the inner wall of the rotating ring 103. The moving part is affected by the rotating ring 103 and adjusts the opening pressure of the water storage cavity 1011 inside the installation head 102. The flushing assembly 200 includes a connecting pipe 201, and a flushing head 202 is provided at the end of the connecting pipe 201. The flushing head 202 has a flushing channel 2021 inside and an isolation component is provided inside the flushing channel 2021. The isolation component is used to isolate the backflow sewage during flushing. The end of the flushing head 202 is also provided with a column 206 and a connecting cap 208 is sleeved on the outer wall of the column 206. The end of the column 206 is provided with a flushing component, and the flushing component changes the flushing mode due to the rotation of the connecting cap 208.

[0024] The mounting head 102 is screwed and fixed to the top of the water storage tank 101 and can be disassembled to facilitate the injection of flushing fluid into the water storage chamber 1011 inside the water storage tank 101. The connecting pipe 201 is connected to the mounting head 102 of the main component 100, so that the flushing component 200 and the main component 100 form a flushing fluid flow path.

[0025] According to the flushing requirements, the rotating ring 103 inside the mounting head 102 is rotated. The rotating ring 103 drives the moving parts on its inner wall to change position or state inside the mounting head 102, thereby adjusting the opening pressure of the water storage chamber 1011 and determining the initial pressure of the flushing fluid. By preset a critical opening pressure, when the pressure generated by the force squeezing the water storage tank 101 is lower than this preset value, the flushing fluid flow passage remains closed to prevent unintentional low-pressure leakage. When the pressure reaches the preset value, the flow passage opens and can stabilize the output pressure near the set value to avoid pressure peaks damaging tissues.

[0026] When the pressure inside the water storage chamber 1011 reaches the adjusted opening pressure, the flushing fluid inside the water storage chamber 1011 enters the connecting pipe 201 through the mounting head 102, and is then transported through the connecting pipe 201 to the flushing channel 2021 of the flushing head 202.

[0027] Rotate the connecting cap 208 sleeved on the outer wall of the column 206. The connecting cap 208 drives the flushing component at the end of the column 206 to move, thereby changing the water outlet mode and switching to a flushing mode that is suitable for the current flushing scenario. The flushing liquid is flushed on the target area after being acted upon by the flushing component.

[0028] During the flushing process, if sewage flows back into the flushing channel 2021, the isolation component in the flushing channel 2021 will block the sewage backflow path to prevent sewage from flowing back into the connecting pipe 201 or the water storage chamber 1011.

[0029] After rinsing is completed, stop applying pressure to the water storage chamber 1011 or lower the pressure in the water storage chamber 1011 below the opening pressure, and the rinsing fluid will stop flowing out, thus completing the rinsing operation. Example

[0030] Reference Figures 5-8 This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0031] Specifically, the flushing component includes a fixing plate 207 on the inner wall of the column 206. A first flushing column 2071 is provided at the center of the fixing plate 207, and the end of the first flushing column 2071 is connected to the flushing channel 2021. A second flushing column 2072 is also arranged in an array on the end face of the fixing plate 207. The ends of the first flushing column 2071 and the second flushing column 2072 are connected to the water outlet 2081 provided at the end of the connecting cap 208.

[0032] The first flushing column 2071 is fixed at the axial position of the fixing plate 207 and is made of rigid material. It is fixed to the inner wall of the column 206 along with the fixing plate 207. The second flushing columns 2072 arranged around the first flushing column 2071 are made of silicone hose material and are deformable as a whole.

[0033] Both ends are connected to the water outlet 2081 at the top of the connecting cap 208. The water inside the column 206 enters the first flushing column 2071 and the second flushing column 2072 and then sprays out from the water outlet 2081.

[0034] Preferably, the end face of the column 206 is provided with an inclined groove 2062, and the end face of the column 206 is also provided with a moving plate 2073 and the end face of the moving plate 2073 is provided with a sliding column 2074. The end of the sliding column 2074 extends to the inner wall of the inclined groove 2062 and slides therewith. The connecting cap 208 is fixed with an output ring 209 inside and the output ring 209 is located at the end of the moving plate 2073. The end face of the output ring 209 is provided with a slide rail 2091 and slides therewith with the sliding column 2074.

[0035] The output ring 209 is fixed inside the connector cap 208. When the connector cap 208 is rotated, the output ring 209 rotates synchronously with the connector cap 208.

[0036] The output ring 209 presses against the moving plate 2073 and engages with the sliding column 2074 on the surface of the moving plate 2073 via the slide rail 2091 on its lower surface. At the same time, since the other end of the sliding column 2074 is in the inclined groove 2062 on the upper surface of the column 206, when the connecting cap 208 is rotated, the output ring 209 rotates synchronously. The slide rail 2091 drives the sliding column 2074 to slide along the slide rail 2091. Since the sliding column 2074 is also embedded in the inclined groove 2062, the inclined structure of the inclined groove 2062 will convert the circumferential motion of the sliding column 2074 into axial motion, thereby driving the moving plate 2073 to move along the axis of the column 206.

[0037] When the moving plate 2073 moves towards the center, the connecting cap 208 rotates and the end of the second flushing column 2072 is fixed to the connecting cap 208. At this time, the second flushing column 2072 surrounds the first flushing column 2071. Simultaneously, the end of the moving plate 2073 squeezes the second flushing column 2072 against the outside of the first flushing column 2071, deforming and blocking it, so that the water flow can no longer pass through the second flushing column 2072 and spray out the outlet 2081. At this time, only the first flushing column 2071 is still connected and sprays a concentrated water flow outward. Since only the first flushing column 2071 is spraying water outward, the water flow rate is relatively large, which is suitable for flushing deep intestinal cavities.

[0038] When the moving plate 2073 moves outward, it no longer squeezes the second flushing column 2072. At this time, the second flushing column 2072 is connected to the water outlet 2081, and the internal water flow can flow through the second flushing column 2072. The second flushing column 2072 and the first flushing column 2071 work together to spray water outward. At this time, the second flushing column 2072 and the first flushing column 2071 spray outward at the same time. Under the same water flow, since multiple water outlets 2081 spray water outward simultaneously, the sprayed water flow is a dispersed water flow or water mist, which is suitable for cleaning sensitive perianal wounds.

[0039] The inner wall of the connecting cap 208 is provided with an array of elastic sheets 2082, and the end face of the elastic sheet 2082 is also provided with an elastic rib 2083. The end of the elastic rib 2083 extends to the inner wall of the limiting groove 2061 opened on the outer wall of the column 206 and engages with it.

[0040] One end of the elastic sheet 2082 is fixed to the inner wall of the connecting cap 208, and the end of the elastic rib 2083 is embedded in the limiting groove 2061 on the outer wall of the column 206. The connecting cap 208 is fixed by the engagement of the end of the elastic rib 2083 with the limiting groove 2061. When the connecting cap 208 rotates, the elastic rib 2083 is affected by the compression of the inner wall of the limiting groove 2061, and the other end of the fixed part moves in the inner wall of the connecting cap 208, so that the elastic rib 2083 is released from the fixation of the limiting groove 2061, allowing the connecting cap 208 to rotate.

[0041] A fixing ring 203 is fixed to the inner wall of the flushing channel 2021, and a float 2031 is provided at the end of the fixing ring 203. A connecting column 2032 is provided at the end of the float 2031, and the end of the connecting column 2032 extends to the other end of the fixing ring 203 and is provided with a connecting block 2033. A second elastic element 2034 is also provided at the end of the connecting block 2033.

[0042] The fixed ring 203 is fixed to the inner wall of the flushing channel 2021, and a channel is opened on its surface for the medium to flow. The float 2031 is located at the upper end of the fixed ring 203, and the connecting column 2032 connected to the float 2031 extends into the lower part of the fixed ring 203. The bottom connecting block 2033 is pushed by the second elastic element 2034, so that the float 2031 moves downward under normal conditions. The flushing channel 2021 is closed by the fit between the float 2031 and the sealing ring 2035.

[0043] Preferably, the inner wall of the flushing channel 2021 is also provided with a flexible check valve 204, and the flexible check valve 204 is located at the end of the float 2031, and the flexible check valve 204 and the float 2031 form an isolation cavity 205.

[0044] The top of the flexible check valve 204 is a duckbill-shaped valve port. When the flushing medium passes through the float 2031, the water pressure reaches the opening pressure of the flexible check valve 204, causing the valve port at its top to open. When the internal flushing pressure drops suddenly or contaminants attempt to flow back into the water storage chamber 1011 along the flushing channel 2021, the flexible check valve 204 automatically closes due to the reverse pressure, blocking most of the contaminants. If a very small amount of contaminants enters the isolation chamber 205 through the tiny gap of the flexible check valve 204, the second elastic element 2034 will push the float 2031 forward, causing the float 2031 to tightly fit the sealing groove of the fixing ring 203, forming a secondary seal, retaining the contaminants in the isolation chamber 205, and completely preventing them from entering the water storage chamber 1011, thus solving the problems of easy leakage and high risk of cross-infection of existing one-way valves.

[0045] In summary, during use, the elastic sheet 2082 inside the connecting cap 208 fixes the connecting cap 208 by engaging with the limiting groove 2061 through the elastic rib 2083, preventing the connecting cap 208 from loosening and causing mode shift during rinsing. When it is necessary to switch rinsing modes, external force is applied manually to rotate the connecting cap 208, causing the elastic rib 2083 inside to undergo slight deformation due to the compression of the limiting groove 2061, allowing it to disengage from the limiting groove 2061 and enabling the connecting cap 208 to rotate smoothly. When the connecting cap 208 rotates, the internal output ring 209 rotates synchronously and drives the motion plate 2073 to move. The motion plate 2073 moves to the corresponding target to change the rinsing mode. Under the restoring force of the elastic sheet 2082, the elastic rib 2083 is re-embedded into the adjacent limiting groove 2061, completing the re-fixation of the connecting cap 208.

[0046] When deep intestinal flushing is required, the connecting cap 208 sleeved on the outer wall of the column 206 is rotated. The connecting cap 208 drives the output ring 209 fixed inside to rotate synchronously. The slide 2091 on the end face of the output ring 209 slides and engages with the slide column 2074 on the end face of the moving plate 2073, causing the slide column 2074 to move along the slide 2091.

[0047] The other end of the sliding column 2074 is embedded in the inclined groove 2062 on the end face of the column 206. The inclined structure of the inclined groove 2062 converts the circular motion of the sliding column 2074 into axial motion, which ultimately drives the moving plate 2073 to move towards the center along the axis of the column 206. When the moving plate 2073 moves towards the center, its end squeezes the second flushing column 2072 surrounding the first flushing column 2071. Since the second flushing column 2072 is made of silicone hose, it can be deformed. At this time, the second flushing column 2072 deforms and blocks. At this time, the water flow in the flushing channel 2021 can only pass through the first flushing column 2071 at the axis of the fixed plate 207 and spray out from the outlet 2081 at the end of the connecting cap 208. When only the first flushing column 2071 is emitting water, the water flow is concentrated and the flow rate is large, which is suitable for the flushing needs of the deep intestinal cavity.

[0048] When it is necessary to select the dispersed water flow or water mist mode to rinse the sensitive perianal wound, the connecting cap 208 is rotated in the opposite direction. The output ring 209 inside rotates in the opposite direction with the connecting cap 208. The slide 2091 drives the slide column 2074 to move in the opposite direction. The slide column 2074 slides in the opposite direction in the inclined groove 2062, which drives the moving plate 2073 to move outward along the axis of the column 206. After the moving plate 2073 moves outward, it no longer squeezes the second flushing column 2072, and the second flushing column 2072 is unblocked. The water flow in the flushing channel 2021 simultaneously enters the first flushing column 2071 and the arrayed second flushing columns 2072, and sprays out from the outlet 2081 at the end of the connecting cap 208. Multiple flushing columns deliver water simultaneously, and the water flow is "dispersed" or "mist" under the same water pressure, avoiding damage to sensitive wounds from high-pressure concentrated water flow, and adapting to the cleaning needs of fragile external perianal wounds.

[0049] During rinsing, the rinsing fluid enters the rinsing channel 2021 inside the rinsing head 202 from the water storage chamber 1011 through the connecting pipe 201. The water pressure of the rinsing fluid acts on the float 2031, pushing the float 2031 upward. At the same time, the float 2031 drives the connecting block 2033 to compress the second elastic element 2034 through the connecting column 2032. After the float 2031 is separated from the sealing seal with the fixed ring 203, the water flow continues to push forward and opens the elastic check valve 204, causing the duckbill-shaped valve port at the top of the elastic check valve 204 to open. The water flow enters the rinsing component to complete the rinsing. At this time, the isolation chamber 205 between the float 2031 and the elastic check valve 204 is in a "conducting state" and only serves as a transition water flow.

[0050] When the flushing pressure drops suddenly, such as when the water tank 101 stops being squeezed or when contaminants attempt to flow back into the water storage chamber 1011 along the flushing channel 2021, the reverse pressure acts on the duckbill-shaped valve port of the elastic check valve 204, and the valve port closes automatically, directly blocking the reverse flow of most contaminants and preventing them from entering the isolation chamber 205.

[0051] At the same time, due to the reduction in flushing pressure, the second elastic element 2034 releases its restoring force, pushing the connecting block 2033 and the connecting column 2032 to move, so that the float 2031 tightly fits into the sealing groove of the fixing ring 203. The float 2031 and the fixed ring 203 form a secondary seal, so that even if a very small amount of contaminants enter the isolation chamber 205 through the tiny gap of the elastic check valve 204, they will be retained in the isolation chamber 205, completely preventing them from entering the connecting pipe 201 or the water storage chamber 1011, thus avoiding contamination of the flushing fluid. Example

[0052] Reference Figures 2-4 This is the third embodiment of the present invention, which is implemented based on the previous embodiment.

[0053] Specifically, the outer wall of the rotating ring 103 is provided with a first groove 1031 and a second groove 1032, and the end of the first protrusion 1021 located at the end of the mounting head 102 extends to the inner wall of the first groove 1031 and slides with it.

[0054] The mounting head 102 is fixed to the end of the water storage tank 101, and the rotating ring 103 is movably mounted above the mounting head 102. The rotating ring 103 is fixed by the first protruding rib 1021 at the end of the mounting head 102, so that the rotating ring 103 can rotate inside the mounting head 102.

[0055] The end of the swivel 103 is also provided with a connector 106 and the end of the connector 106 is connected to the end of the connecting pipe 201. The inner wall of the connector 106 is also provided with a second rib 1061 and the end of the second rib 1061 extends to the inner wall of the second groove 1032 and slides with it.

[0056] The end of the connector 106 is screwed to the top of the connector 201. The connector 106 is sleeved on the outer wall of the end of the swivel ring 103 and installed on the outside of the swivel ring 103 by the inner second rib 1061.

[0057] The moving part includes a threaded block 104 and the threaded block 104 is disposed on the inner wall of the rotating ring 103. The inner wall of the threaded block 104 is also provided with a moving column 105. The inner wall of the moving column 105 is provided with a cavity 1051 and the end of the cavity 1051 is provided with an opening 1052. The outer wall of the moving column 105 is also provided with a first elastic element 1053.

[0058] The threaded block 104 is installed inside the rotating ring 103. At the same time, the bottom of the threaded block 104 is affected by the limiting post on the inner wall of the mounting head 102. The limiting post extends into the interior of the threaded block 104, so that when the rotating ring 103 rotates, the threaded block 104 only moves up and down on the inner wall of the rotating ring 103 and cannot rotate synchronously with the rotating ring 103.

[0059] Similarly, the movable column 105 is located inside the threaded block 104, and the bottom of the movable column 105 is inside the mounting head 102. The flexible sealing ring on the outer wall prevents the flushing fluid in the water storage chamber 1011 from entering the interior of the mounting head 102. Similarly, two flexible sealing rings are also provided at the top of the movable column 105, one below the opening 1052 and the other at the top of the movable column 105. The movable column 105 is driven by the first elastic element 1053, and its top is pressed against the inner wall of the connector 106. The opening 1052 is sealed by the two flexible sealing rings above and below.

[0060] The distance between the threaded block 104 and the first elastic element 1053 is adjusted by rotating the ring 103 and adjusting the pressure of the first elastic element 1053. This changes the preload when the top of the moving column 105 is opened. When the pressure applied to the water tank 101 is less than the preload of the first elastic element 1053, the moving column 105 will not move, thus avoiding unintentional low-pressure leakage.

[0061] When the pressure reaches the preset value, the moving column 105 moves upward, and the opening 1052 protrudes from the inner wall of the connector 106 and opens, stabilizing the output pressure near the set value and preventing pressure peaks from damaging tissues. This mechanism ensures that different operators can output a uniform and safe water flow.

[0062] Preferably, the end of the flushing head 202 is also provided with a mounting plate 301, the end of the mounting plate 301 is provided with an airbag 302 and the outer wall of the airbag 302 is connected with an air supply pipe 303, and the end of the air supply pipe 303 is also connected with an airbag pump 304.

[0063] The mounting plate 301 is located at the bottom of the flushing head 202. The airbag pump 304 inflates the airbag 302 until it fits tightly against the perianal skin to form a ring seal. The inflation amount can be controlled by hand, with the standard being that the patient has no obvious discomfort and there is no sewage leakage.

[0064] After the flushing is started, the wastewater containing contaminants cannot be sprayed out of the perianal gaps due to the sealing effect of the airbag 302. Instead, it can only flow out naturally along the outer wall of the flushing head 202 or the patient's position, thus avoiding contamination of the operator or the environment.

[0065] In summary, during use, the opening pressure of the water storage chamber 1011 is pre-adjusted according to the needs. The threaded block 104 is restricted from rotating by the limiting post on the inner wall of the mounting head 102. When the rotating ring 103 rotates, the thread on its inner wall drives the threaded block 104 to rise and fall along the axis of the rotating ring 103. When the threaded block 104 rises and falls, it squeezes or relaxes the first elastic element 1053. When the threaded block 104 moves down, it compresses the first elastic element 1053 and increases the pre-tightening force of the moving column 105. When the threaded block 104 moves up, it relaxes the first elastic element 1053 and decreases the pre-tightening force of the moving column 105 until the opening pressure is set to meet the current flushing scenario. For example, postoperative wound flushing requires low pressure, while deep cleaning requires slightly higher pressure.

[0066] When accidentally touched or slightly squeezed, the pressure inside the water storage chamber 1011 is insufficient to overcome the pre-tightening force of the first elastic element 1053 on the moving column 105. The moving column 105 remains stationary, and its top continues to press against the inner wall of the connector 106. The opening 1052 is blocked by the flexible sealing ring, and the flushing fluid cannot enter the connector 106 and the connecting pipe 201 through the opening 1052, thus completely avoiding unintentional low-pressure leakage.

[0067] During normal flushing, the pressure inside the water storage chamber 1011 overcomes the pre-tightening force of the first elastic element 1053, pushing the moving column 105 upward along the inner wall of the threaded block 104; after the moving column 105 moves upward, the opening 1052 is exposed from the inner wall of the connector 106, and the flushing liquid in the water storage chamber 1011 enters the cavity 1051 of the moving column 105 through the opening 1052, then flows into the connector 106, the connecting pipe 201, and finally to the flushing head 202; The elastic force of the first elastic element 1053 can buffer the instantaneous squeezing pressure of the water tank 101, such as pressure peaks caused by uneven force applied by the operator, so that the opening 1052 of the moving column 105 remains stably open and the output pressure is always stable near the preset value.

[0068] Before flushing, the airbag pump 304 is squeezed to inflate the airbag 302 through the air supply tube 303. After inflation, the airbag 302 gradually expands until it fits tightly against the patient's perianal skin, forming an annular seal around the flushing head 202. When the flushing fluid flushes the target area through the flushing head 202, the wastewater containing contaminants is blocked by the annular seal of the airbag 302 and cannot be sprayed at high speed through the gap between the flushing head 202 and the perianal skin. The blocked wastewater can only flow naturally along the outer wall of the flushing head 202 or be discharged naturally to the preset collection device according to the patient's position.
