Description

Technical Field

[0001] This invention relates to a multifunctional stoma cleaning device. Background Technology

[0002] In clinical nursing practice, patients with ostomies rely on disposable ostomy bags for collecting their excrement, which must be discharged through an abdominal stoma. Due to the strong pollutant and odorous nature of the excrement, ostomy bags need frequent changes, especially for patients with high discharge volumes or special conditions, who may require multiple changes daily. This not only imposes a significant financial burden but also increases the difficulty of care. To reduce consumable costs and improve ease of use, some patients choose to wash and reuse reusable ostomy bags. However, during stoma cleaning and bag changing, the operator's hands are easily contaminated and require immediate cleaning. Currently, most commercially available stoma cleaning devices only have dedicated stoma cleaning nozzles, typically with a ring or radial water outlet design. The water flow disperses outwards, aiming to gently rinse the skin around the stoma and avoid irritation. While these nozzles are suitable for cleaning the stoma area, they are unsuitable for concentrated rinsing of localized areas such as hands, as the dispersed water pressure and uncontrollable direction make it difficult to effectively remove dirt from hands. If hand cleaning is required, users often need to find alternative water sources or use other cleaning equipment, which is cumbersome and does not meet hygiene standards. In addition, existing stoma cleaning devices generally lack flow regulation functions, making it impossible to flexibly adjust the water output according to actual cleaning needs, which further limits their applicable scenarios. Summary of the Invention

[0003] This invention discloses a multifunctional stoma cleaning device, which aims to solve the problems mentioned above.

[0004] The present invention adopts the following solution: A multifunctional stoma cleaning device includes: a main body configured to connect to a water source; a water distribution connector configured to connect to the main body, the water distribution connector having a water distribution chamber and a first water outlet and a second water outlet connected to the water distribution chamber; and a switching structure, one end of which is positioned inside the water distribution chamber, and the other end of which is positioned outside the water distribution connector for user operation; the switching structure allows water in the water distribution chamber to flow to either the first or second water outlet; a first water nozzle is located at the first water outlet, and a stoma cleaning device is located at the second water outlet; when the main body is filled with water, the switching structure maintains water flow from either the first or second water outlet under the action of the water flow; when the main body is closed, the switching structure blocks the second water outlet, and the first water outlet is open so that water will flow from the first water outlet the next time the main body is filled with water.

[0005] In this embodiment of the invention, the stoma cleaning device includes a connecting pipe with one end sealed. The connecting pipe is bent in shape, and spray holes are arranged on the outer periphery of one end of the connecting pipe. The other end of the connecting pipe is detachably connected to a second water outlet.

[0006] In this embodiment of the invention, a locking cover is also included. The inner circumference of the locking cover is configured to be screwed into the outer circumference of the second water outlet. The locking cover is provided with a through hole, and the connecting pipe is configured to be inserted into the through hole. The outer circumference of the other end of the connecting pipe is provided with a flange protruding outward. The side wall of the locking cover located around the through hole can abut against the flange. When the locking cover fixes the connecting pipe to the water distribution connector, the upper end face of the flange can fit tightly against the lower end face of the second water outlet.

[0007] In this embodiment of the invention, the first water outlet is disposed on the front side of the water distribution connector, the second water outlet is disposed below the water distribution connector, and the main body is connected to the upper part of the water distribution connector so that water is guided from top to bottom into the water distribution chamber. The first water outlet nozzle is configured as a water softener.

[0008] In this embodiment of the invention, the switching structure includes a switching rod disposed within the water distribution chamber. An opening communicating with the water distribution chamber is disposed on one side wall of the water distribution connector. One end of the switching rod extends outward through the opening to the outside of the water distribution connector. The switching rod can rotate within the water distribution chamber. A settling groove is disposed on the switching rod. A sealing gasket is disposed at the opening of the settling groove. An elastic element is disposed within the settling groove between the bottom of the settling groove and the sealing gasket. Under the action of the elastic element, the sealing gasket is configured to block the inlet end of the first or second water outlet, so that the water flow in the water distribution chamber is directed to the first or second water outlet.

[0009] In this embodiment of the invention, the switching rod is provided with a pair of sealing rings along its axial direction, the pair of sealing rings being located on both sides of the first water outlet and the second water outlet; it also includes a knob, the knob being configured to be connected to one end of the switching rod, the knob being configured to be operable to drive the switching rod to rotate within the water distribution chamber, so that the sealing gasket switches between the positions of blocking the first water outlet and the second water outlet.

[0010] In this embodiment of the invention, the main body is provided with a water inlet channel that can be connected to a water source. The water inlet channel is configured to be connected to a water distribution chamber. The water inlet channel is provided with a regulating device for controlling the flow rate. The axial direction of the water inlet channel is arranged along the front-rear direction of the main body.

[0011] In this embodiment of the invention, the adjusting device is configured as a movable shaft, the axial direction of which is perpendicular to the axial direction of the water inlet channel; the main body is provided with a transverse through-hole, the through-hole being configured to communicate with the water inlet channel; the outer diameter of the movable shaft is adapted to the inner diameter of the through-hole; a pair of sealing rings are provided on the outer periphery of the movable shaft, the pair of sealing rings being positioned on both sides of the water inlet channel; an inwardly recessed annular groove is provided on the outer peripheral wall of the movable shaft between the two sealing rings; the movable shaft is disposed within the through-hole and can move along its axial direction, thereby changing the position of the annular groove relative to the water inlet channel, thus changing the flow rate of the water inlet channel at the rear end of the annular groove.

[0012] In this embodiment of the invention, a reset element is also included, which is configured to drive the switching mechanism to reset.

[0013] In this embodiment of the invention, the reset component is configured as a torsion spring. One end of the torsion spring is connected to the water distribution connector, and the other end of the torsion spring is connected to the knob. The knob can rotate synchronously with the switching rod. The switching rod is also equipped with a water baffle. When the first water outlet is blocked and water flows through the second water outlet, the water flow impacts the water baffle from top to bottom, so that the force of the water flow on the switching rod is greater than the force of the torsion spring on the switching rod, thereby keeping water flowing out of the second water outlet. When the main body is not flowing with water, the switching rod blocks the second water outlet under the force of the torsion spring, and the first water outlet opens.

[0014] This invention provides a multifunctional stoma-specific cleaner with the following advantages: By integrating two water outlet modes on a single spray gun body, it solves the problem of not being able to clean hands immediately after contamination in stoma care, effectively reducing the risk of cross-infection; the mechanical switching structure combined with a water flow self-locking and water cut-off reset mechanism ensures clear operation logic and safe use; the stoma cleaning device achieves quick disassembly and reliable sealing through the double fit of the locking cap and flange, facilitating daily maintenance and disinfection; the flow regulation device uses a lateral moving shaft and an annular groove, with a simple structure and good adjustment linearity, meeting the needs of different flushing intensities; the overall structure is compact, the connection relationship of each component is clear, and the sealing measures are perfect.

[0023] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Referring to the accompanying drawings, the present invention provides a multifunctional stoma cleaning device, the overall structure of which includes a body 1, a water distribution connector 2, a switching structure, a first water outlet nozzle 3, and a stoma cleaning device 4. The body 1 serves as the main support structure for the spray gun, and its interior has a water inlet channel 11 extending along its length (also its longitudinal direction). One end of the water inlet channel 11 is equipped with a standard quick-connect interface for quick connection to a hospital water supply system or a household hose, and the other end is connected to the water distribution chamber 20 inside the water distribution connector 2, realizing the transmission path of water flow from an external water source into the interior of the spray gun. The water distribution connector 2 is fixedly connected to the lower front end of the main body 1. It preferably uses a threaded connection or a snap-fit ​​structure, but can also be integrally injection molded with the main body 1 to improve sealing and structural rigidity. The water distribution connector 2 forms a sealable water distribution chamber 20, which has two outlets: a first outlet 21 located at the front and a second outlet 22 located at the bottom, corresponding to the regular hand washing mode and the stoma-specific flushing mode, respectively. The first outlet is the default initial outlet, meaning that water always flows from the first outlet when the system is turned on, thus preventing splashing from the stoma cleaning device connected to the second outlet. The water distribution connector can be connected to the main body using screws.

[0025] The switching structure includes a switching lever 5 and a knob 6. The switching lever 5 is horizontally inserted into the water distribution chamber 20, with one end extending to the outside through an opening 23 on the side wall of the water distribution connector 2, and is fixedly connected to the knob 6. The outer surface of the knob 6 has anti-slip textures and can be marked with "ostomy" and "handwashing" labels to help users identify the current working status. The switching lever 5 has a recess 51, the opening of which faces the inlet end of the outlet to be blocked. Inside the recess 51, from bottom to opening, are installed an elastic element 52 and a sealing gasket 53. The elastic element 52 is a compression spring, and the preload of the spring is sufficient to keep the sealing gasket 53 in contact with the inlet ends of the two outlets without external force. When the knob 6 is rotated, causing the switching lever 5 to rotate, the sealing gasket 53 blocks the inlet end of the first outlet 21 or the second outlet 22, thereby directing the water flow to the unblocked outlet. Two sealing rings 54 are fitted along the axial direction of the switching rod 5, located on both sides of the water inlet channel of the first water outlet 21 and the second water outlet 22, respectively, to prevent water from leaking along the gap between the switching rod 5 and the inner wall of the water distribution chamber 20, and to ensure the sealing reliability during the switching process.

[0026] A first water nozzle 3 is installed at the first water outlet 21. This first water nozzle 3 is a water softener, suitable for gentle rinsing of hands or skin surfaces, avoiding irritation to sensitive areas. A stoma cleaning device 4 is connected to the second outlet 22. The stoma cleaning device 4 includes a beveled connecting pipe 41 with one end closed. The outer peripheral wall of the connecting pipe 41 is provided with multiple spray holes 42, which are distributed in a spiral or annular array. The stoma cleaning device 4 is detachably connected to the second outlet 22. Specifically, the outer peripheral of the second outlet 22 is provided with external threads, and it also includes a locking cover 8. The inner peripheral of the locking cover 8 is provided with internal threads that match the external threads. The center of the locking cover 8 is provided with a through hole 81, and the connecting pipe 41 passes through the through hole. The outer peripheral of the connecting end of the connecting pipe 41 is provided with an outwardly protruding annular flange 43. When the locking cover 8 is tightened to the second outlet 22, the lower end face of the locking cover 8 abuts against the upper end face of the flange 43, and at the same time, the upper end face of the flange 43 is tightly fitted with the lower end face of the second outlet 22, forming an axial limiting and double sealing structure to prevent water from leaking from the connection and to facilitate daily disassembly, disinfection or replacement. In use, the connecting pipe is bent, with two parts forming an acute angle. The part connected to the second water outlet is set perpendicular to the first water outlet, while the other part is upturned. The spray hole is located on this upturned part. Preferably, the height of the spray hole is higher than the height of the first water outlet nozzle, so that the first water outlet nozzle can clean the upturned part.

[0027] The main body 1 is also equipped with a flow regulating device, which includes a moving shaft 7 that runs horizontally through the main body 1. Both ends of the moving shaft are located on the outside of the main body, and the axial direction of the moving shaft 7 is perpendicular to the axial direction of the water inlet channel 11. The main body 1 is provided with a connecting hole 12 that communicates with the water inlet channel 11, and the moving shaft 7 passes through the connecting hole 12. Two sealing rings 71 are provided on the outer periphery of the moving shaft 7, respectively located on both sides of the water inlet channel 11. An annular groove 72 is provided on the outer periphery of the moving shaft 7 between the two sealing rings. By pushing and pulling along the axial direction of the moving shaft 7, the overlap area between the annular groove and the water inlet channel 11 is changed, thereby adjusting the cross-sectional area of ​​the water flowing through the water inlet channel 11, realizing stepless adjustment of the water flow rate, and meeting the requirements of different flushing intensities. That is to say, the water flow needs to pass through the annular groove before it can flow to the rear end of the water inlet channel.

[0028] Specifically, the spray gun also includes a reset component, which is a torsion spring 9. One end of the torsion spring 9 is fixed to the housing of the water distribution connector 2, and the other end is fixed to the inside of the knob 6. The switching lever 5 is also equipped with a water baffle 55, which is located in the water distribution chamber 20 and in the water flow path. In its natural state (when water is flowing from the first outlet by default), the water baffle is located behind the switching lever. The inlet end of the second outlet is located behind the inlet end of the first outlet. When the water flows from the main body to the water distribution chamber, it flows downward at an angle from back to front. By default, water is flowing from the first outlet. When switching to the stoma cleaning device, the knob is turned, causing the water baffle to rotate with the switching lever, changing the water baffle from a vertical (or other angle setting) setting to a horizontal setting. In this way, the water flowing into the water distribution chamber will impact the water baffle 55. The driving torque exerted by the water flow on the water baffle 55 is greater than that provided by the torsion spring 9. The reset torque keeps the switching lever 5 in the open position of the second outlet 22. When the water source is turned off and the water flow stops, the torsion spring 9 releases its stored energy, driving the knob 6 and the switching lever 5 to rotate, causing the sealing gasket 53 to seal the water inlet of the second outlet 22, and at the same time releasing the seal on the first outlet 21. This automatically switches the water output state back to the default mode of the first outlet 21 being open and the second outlet 22 being closed, ensuring that the default water output mode is hand washing mode when used next time, and avoiding accidental operation that could cause the stoma water to spray onto the hands and cause contamination.

[0029] In actual use, the user first connects the spray gun to the water source through the water inlet channel 11 of the main body 1; then rotates the knob 6 to the "handwashing" position. At this time, the switching lever 5 drives the sealing gasket 53 to block the second water outlet 22, and the water flows out from the first water outlet 21 through the water distribution chamber 20, forming a gentle water flow for hand washing after passing through the water softener; when it is necessary to clean the stoma, the user rotates the knob 6 to the "stoma" position, the sealing gasket 53 blocks the first water outlet 21, the water flow turns to the second water outlet 22, enters the bend-shaped connecting pipe 41 and rinses the skin around the stoma in all directions through the circumferentially distributed spray holes 42; during the stoma cleaning process, the water flow continuously impacts the baffle plate 55, and the generated torque overcomes The torsion spring 9 maintains the second outlet 22 in the open state; after cleaning, the water source is turned off and the water flow disappears, the torsion spring 9 releases its elasticity, driving the switching rod 5 to automatically rotate and reset to the "handwashing" position; if the stoma cleaning device 4 needs to be replaced or disinfected, the user loosens the locking cap 8, removes the locking cap and stoma cleaning device from the water connector, and pulls the connecting pipe 41 out of the perforation to complete the disassembly; during installation, the connecting pipe 41 is inserted into the perforation and the locking cap 8 is tightened, and the flange 43 fits against the lower end face of the second outlet 22 to form a seal; according to the cleaning needs, the user pushes and pulls the moving shaft 7 of the flow regulating device to adjust the overlap area between the annular groove and the water inlet channel 11, thereby controlling the water flow rate.

[0030] When the main body is irrigated, the switching structure can keep either the first or second water outlet from discharging water under the action of the water flow; when the main body is shut off, the switching mechanism can block the second water outlet and keep the first water outlet open, so that water is discharged from the first water outlet every time the main body goes from shut off to irrigated. Preferably, the water outlets of the first water nozzle and the ostomy cleaning device are both located on the front side of the main body.

[0031] The main body and the water distribution connector form an inlet chamber 12 that can be connected to a water source. The two can be locked together with bolts. The water flow in the inlet chamber is configured to flow into the water distribution chamber. A sealing ring 13 is provided between the water distribution connector and the main body to prevent water leakage between the main body and the water distribution connector. At the same time, the water flow in the inlet chamber can flow from back to front and downwards into the water distribution chamber. That is to say, there is a certain drop between the inlet chamber and the water distribution chamber. This allows the water flow to carry a little potential energy (impact force) when entering the water distribution chamber, and then act on the baffle. Especially when water is discharged from the second outlet, the potential energy generated by the drop of the water flow is greater than that when water is discharged from the first outlet, which better overcomes the force of the torsion spring.

[0032] The rotation angle of the switching lever 5 is limited to 90°, corresponding to two working positions: The first position is that the sealing gasket 53 blocks the second outlet 22, and the water flows out through the first outlet 21. This is the default state (initial state). In this state, the baffle is vertically set inside the water distribution chamber, so the water flow needs to bypass the baffle to flow out from the first outlet, which slows down the water flow speed and works well with the water softener. At the same time, the water flow impacts the baffle, and the switching lever will not rotate in any direction when the switching angle is limited. The second position is that the sealing gasket 53 blocks the first outlet 21, and the water flows through the second outlet 22 to the stoma cleaning device 4. In this state, the baffle is set horizontally. At this time, the water flow directly impacts the baffle. The impact force of the water flow is greater than the force of the torsion spring, and the water flow maintains this state.

[0033] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
