Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an auxiliary device for perineal care. Background Technology

[0002] In perineal care, the washing device is a core tool, and balancing the water flow intensity with the patient's comfort has always been a key challenge in clinical nursing. For postpartum, postoperative, or long-term bedridden patients, the perineal area often has excessive secretions, such as lochia and inflammatory secretions, which require thorough cleaning to reduce the risk of infection.

[0003] Most existing perineal care aids have a single water flow setting or a rough classification. When secretions are tightly adhered, a larger water flow is required to effectively clean them. However, a larger water flow directly impacts the sensitive mucous membrane of the vulva, which can easily cause discomfort such as stinging and spasms. This is especially true for patients with wounds or mucous membrane congestion, as it may exacerbate local irritation or even cause secondary damage. If a smaller water flow is used to avoid discomfort, it is difficult to remove stubborn secretions, resulting in incomplete cleaning and increasing the risk of infection. Summary of the Invention

[0004] The purpose of this invention is to address the problem that in existing technologies, water flow adjustment is mostly limited to a single setting or coarse gradations. When secretions are tightly adhered, a larger water flow is required for effective cleaning. However, a larger water flow directly impacts the sensitive mucosa of the vulva, easily causing discomfort such as stinging and spasms. This is especially problematic for patients with wounds or mucosal congestion, potentially exacerbating local irritation or even causing secondary damage. If a smaller water flow is used to avoid discomfort, it is difficult to remove stubborn secretions, leading to incomplete cleaning and increasing the risk of infection. Therefore, this invention proposes an auxiliary device for perineal care.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary device for perineal care includes a reservoir and further includes: A cleaning facility that sprays cleaning solutions onto a patient's skin; The cleaning mechanism includes a top cover threaded to the top of the liquid storage cylinder. A micro pump is fixedly installed on the top of the top cover. The outlet end of the micro pump is connected to a three-way pipe, and the inlet end of the micro pump is connected to an inlet pipe. One end of the three-way pipe is connected to an outlet pipe, and the end of the outlet pipe away from the three-way pipe is connected to a connecting pipe. A spray head is provided at one end of the connecting pipe, and spray holes are opened on the outer surface of the spray head. Adjustment mechanism, used to make the spray head intermittently contact the patient's skin.

[0006] Preferably, the adjustment mechanism includes a support rod fixed to the top of the top cover, a mounting base fixed to the top of the support rod, a mounting box fixed to the top of the mounting base, and a circular shell fixed to the back of the mounting box.

[0007] Preferably, an impeller is provided inside the circular shell, and a rotating shaft is fixed at the center of the impeller. The rotating shaft is rotatably connected to the mounting box and the circular shell through a bearing. The end of the three-way pipe away from the first outlet pipe is connected to the second outlet pipe, and the end of the second outlet pipe away from the three-way pipe is connected to the circular shell. A bend is connected between the circular shell and the first outlet pipe. When the cleaning fluid flows into the circular shell from the second outlet pipe, it can drive the impeller to rotate.

[0008] Preferably, a turntable is fixed to the end of the rotating shaft away from the impeller, a push rod is fixed to the side of the turntable away from the rotating shaft, a movable housing slides on the outer surface of the push rod, an extrusion rod is fixedly connected to the movable housing, a connecting block is fixed inside the spray head, and the end of the extrusion rod away from the movable housing is connected to the connecting block through a blocking member.

[0009] Preferably, the end of the connecting pipe near the spray head is connected to a liquid outlet hose, and the end of the liquid outlet hose away from the connecting pipe is connected to the spray head.

[0010] Preferably, a control valve is installed on the outer surface of the first liquid outlet pipe, and a control valve is installed on the outer surface of the second liquid outlet pipe.

[0011] Preferably, the blocking component includes a piston tube communicating between the mounting box and the connecting tube, the extrusion rod being slidably connected to the piston tube, a fixed plate being fixedly installed inside the piston tube, a piston plate being fixed at the end of the extrusion rod away from the movable housing, the piston plate sliding inside the piston tube, and a crossbar being fixed to the side of the piston plate, the crossbar being slidably connected to the fixed plate.

[0012] Preferably, a sealing disc is fixed to the end of the crossbar away from the piston disc, the length of the sealing disc is greater than the diameter of the outlet pipe, and a connecting rod is fixed between the sealing disc and the connecting block.

[0013] Preferably, the piston tube is provided with an auxiliary mechanism for wiping secretions. The auxiliary mechanism includes an air outlet hose communicating with the piston tube, and a rubber convex pad is communicated on the outer surface of the spray head. The end of the air outlet hose away from the piston tube is communicated with the spray head.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the adjustment mechanism, the mounting base, mounting box, circular shell, impeller, rotating shaft, turntable, push rod, moving shell, squeezing rod, and connecting block work together. When there is a lot of secretion, the cleaning solution can flow from the outlet pipe into the circular shell to drive the impeller to rotate, causing the rotating shaft to drive the turntable to rotate. The push rod pushes the squeezing rod through the moving shell, thereby causing the spray head to move intermittently. This allows the rubber convex pad to intermittently contact the patient's skin. The rubber convex pad can gently wipe the skin surface, and the water flow can carry away the secretions, reducing the direct impact on the mucous membrane. The massage effect of the convex points can also promote local blood circulation and relieve the tension during rinsing. It can be disinfected separately after use to avoid cross-infection.

[0015] 2. Through the setting of the blocking components, the piston tube, fixed plate, piston disc, cross rod, sealing disc and connecting rod cooperate with each other. The squeezing rod drives the piston disc to slide in the piston tube, so that the cross rod pushes the sealing disc to intermittently open or close the liquid outlet channel, realizing the pulse spray of cleaning fluid. This avoids continuous large water flow impacting the skin, reducing discomfort while ensuring the secretion removal effect. In addition, during the repeated movement of the piston disc, the rubber convex pad can also be raised, which can play a role in wiping the skin surface and massaging to promote local blood circulation.

[0016] 3. Through the auxiliary mechanism, the air outlet hose and the rubber convex pad work together. The sliding of the piston disc inside the piston tube allows air to enter the spray head through the air outlet hose and into the rubber convex pad, causing the rubber convex pad to bulge and shrink repeatedly. When the rubber convex pad bulges, it can gently wipe away secretions on the skin surface. Combined with water rinsing, it enhances the cleaning effect. Moreover, the rubber material is soft and skin-friendly, avoiding damage to sensitive skin. When the rubber convex pad shrinks, it can make it easier to shake off secretions on its surface, making it convenient for the next wiping. Attached Figure Description

[0019] 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.

[0020] Example 1, refer to Figures 1-8 An auxiliary device for perineal care, comprising a fluid storage cylinder 1, and further comprising: A cleaning facility that sprays cleaning solutions onto a patient's skin; The cleaning mechanism includes a top cover 11 threadedly connected to the top of the liquid storage cylinder 1. A micro pump 12 is fixedly installed on the top of the top cover 11. The outlet end of the micro pump 12 is connected to a three-way pipe 10. The inlet end of the micro pump 12 is connected to an inlet pipe 17. One end of the three-way pipe 10 is connected to an outlet pipe 13. The end of the outlet pipe 13 away from the three-way pipe 10 is connected to a connecting pipe 14. One end of the connecting pipe 14 is provided with a spray head 15. The outer surface of the spray head 15 is provided with spray holes 16. Adjustment mechanism, used to make the spray head 15 intermittently contact the patient's skin.

[0021] Furthermore, the adjustment mechanism includes a support rod 20 fixed to the top of the top cover 11, a mounting base 21 fixed to the top of the support rod 20, a mounting box 22 fixed to the top of the mounting base 21, and a circular shell 23 fixed to the back of the mounting box 22.

[0022] Furthermore, an impeller 25 is provided inside the circular shell 23, and a rotating shaft 26 is fixed at the axis of the impeller 25. The rotating shaft 26 is rotatably connected to the mounting box 22 and the circular shell 23 through bearings. The end of the three-way pipe 10 away from the first outlet pipe 13 is connected to the second outlet pipe 24. The end of the second outlet pipe 24 away from the three-way pipe 10 is connected to the circular shell 23. A bend pipe 27 is connected between the circular shell 23 and the first outlet pipe 13. When the cleaning fluid flows into the circular shell 23 from the second outlet pipe 24, it can drive the impeller 25 to rotate.

[0023] Furthermore, a turntable 28 is fixed to one end of the rotating shaft 26 away from the impeller 25, and a push rod 29 is fixed to one side of the turntable 28 away from the rotating shaft 26. A movable housing 210 slides on the outer surface of the push rod 29, and a pressing rod 211 is fixedly connected to the movable housing 210. A connecting block 212 is fixed inside the spray head 15, and one end of the pressing rod 211 away from the movable housing 210 is connected to the connecting block 212 through a blocking member.

[0024] Furthermore, the end of the connecting pipe 14 near the spray head 15 is connected to the liquid outlet hose 213, and the end of the liquid outlet hose 213 away from the connecting pipe 14 is connected to the spray head 15.

[0025] Furthermore, a control valve 214 is installed on the outer surface of the discharge pipe 13, and a control valve 215 is installed on the outer surface of the discharge pipe 24.

[0026] When using the product, place the cleaning solution at a suitable temperature into the storage cylinder 1 and tighten the top cap 11. Place the storage cylinder 1 next to the patient's body and aim the spray head 15 at the perineal area that needs to be cleaned. Start the micro pump 12 to generate suction at the bottom of the inlet pipe 17, drawing the cleaning solution from the inlet pipe 17 into the three-way pipe 10. At this time, control valve 1 214 opens and control valve 2 215 closes. The cleaning solution then enters the outlet pipe 13 from the three-way pipe 10 and from the outlet pipe 13 into the connecting pipe 14 and the spray head 15, and is then sprayed from the spray hole 16 onto the patient's perineal area for cleaning.

[0027] It should be noted that the above content is existing technology, so it will not be elaborated on here. Considering that in existing technologies, water flow adjustment is mostly a single level or a rough grade, when secretions are tightly adhered, a larger water flow is required for effective cleaning. However, a large water flow directly impacts the sensitive mucosa of the vulva, which can easily cause discomfort such as stinging and spasms. Especially for patients with wounds or mucosal congestion, it may aggravate local irritation or even cause secondary damage. If a small water flow is selected to avoid discomfort, it is difficult to remove stubborn secretions, creating the hidden danger of incomplete cleaning and increasing the risk of infection. The following improvements are made to address this issue: During the cleaning process, if there is a lot of secretion, control valve 1 214 can be closed and control valve 2 215 can be opened. When the micro pump 12 is started, the secretion will enter the outlet pipe 2 24 from the three-way pipe 10, and then enter the circular shell 23 from the outlet pipe 2 24. The outlet pipe 2 24 is positioned opposite the impeller 25. When the cleaning fluid enters the circular shell 23, it will drive the impeller 25 to rotate. Since the bend pipe 27 connects the circular shell 23 and the outlet pipe 1 13, after driving the impeller 25 to rotate, the cleaning fluid will enter the outlet pipe 1 13 from the bend pipe 27, and continue to be sprayed from the connecting pipe 14 and the spray hole 16 to the part of the patient that needs to be cleaned.

[0028] When the impeller 25 rotates, it drives the rotating shaft 26 to rotate. The rotating shaft 26 is connected to the turntable 28, and the rotating shaft 26 also drives the turntable 28 to rotate. The turntable 28 drives the push rod 29 to make a circular motion. Since the push rod 29 is slidably connected to the moving housing 210 and the squeezing rod 211 is limited, it also drives the moving housing 210 and the squeezing rod 211 to make a reciprocating motion left and right. Through the connection of the blocking component, the squeezing rod 211 drives the connecting block 212 and the spray head 15 to make a reciprocating motion left and right together. Through the setting of the liquid outlet hose 213, the spray head 15 can be displaced a certain distance without affecting the movement of the blocking component.

[0029] The further advantage of the above is that the push rod 29 pushes the squeezing rod 211 through the moving housing 210, thereby causing the spray head 15 to move intermittently to contact the patient's skin, so that the rubber convex pad 42 intermittently contacts the patient's skin. The rubber convex pad 42 can gently wipe the skin surface, and the water flow can carry away secretions, reducing the direct impact on the mucous membrane. The massage effect of the convex points can also promote local blood circulation and relieve the tension during rinsing. After use, it can be disinfected separately to avoid cross-infection.

[0030] It should be noted that an alternative method to drive the impeller 25 to rotate via the cleaning fluid is to drive the impeller 25 to rotate via a motor.

[0031] Example 2, refer to Figures 1-8 An auxiliary device for perineal care, comprising a fluid storage cylinder 1, and further comprising: A cleaning facility that sprays cleaning solutions onto a patient's skin; The cleaning mechanism includes a top cover 11 threadedly connected to the top of the liquid storage cylinder 1. A micro pump 12 is fixedly installed on the top of the top cover 11. The outlet end of the micro pump 12 is connected to a three-way pipe 10. The inlet end of the micro pump 12 is connected to an inlet pipe 17. One end of the three-way pipe 10 is connected to an outlet pipe 13. The end of the outlet pipe 13 away from the three-way pipe 10 is connected to a connecting pipe 14. One end of the connecting pipe 14 is provided with a spray head 15. The outer surface of the spray head 15 is provided with spray holes 16. Adjustment mechanism, used to make the spray head 15 intermittently contact the patient's skin.

[0032] Furthermore, the blocking component includes a piston tube 31 connecting the mounting box 22 and the connecting tube 14, a pressing rod 211 slidably connected to the piston tube 31, a fixed plate 32 fixedly installed inside the piston tube 31, a piston plate 33 fixed at the end of the pressing rod 211 away from the movable housing 210, the piston plate 33 sliding inside the piston tube 31, and a crossbar 34 fixed to the side of the piston plate 33, the crossbar 34 slidably connected to the fixed plate 32.

[0033] Furthermore, a sealing disc 35 is fixed to the end of the crossbar 34 away from the piston disc 33. The length of the sealing disc 35 is greater than the diameter of the outlet pipe 13. A connecting rod 36 is fixed between the sealing disc 35 and the connecting block 212.

[0034] It should be noted that, considering that simply wiping the skin surface intermittently with the spray head 15 and the rubber pad 42, while continuously rinsing, still causes discomfort to the patient's skin, the following improvements are made: The piston disc 33 is connected to the extrusion rod 211. When the push rod 29 makes a circular motion, it drives the moving housing 210 and the extrusion rod 211 to reciprocate. This also drives the piston disc 33 to make piston motion in the piston tube 31. The piston disc 33 is connected to the cross rod 34. The piston disc 33 drives the cross rod 34 and the sealing disc 35 to slide back and forth in the piston tube 31 and the connecting pipe 14. When the sealing disc 35 covers the outlet of the outlet pipe 13, it will block the outlet of the outlet pipe 13. When the sealing disc 35 moves away from the outlet of the outlet pipe 13, the water will flow out again. Therefore, through the reciprocating motion of the sealing disc 35, the cleaning fluid in the outlet pipe 13 will intermittently flow into the spray head 15 and intermittently spray out from the spray hole 16. Through the connection of the connecting rod 36, the sealing disc 35 will drive the spray head 15 to move together when it moves.

[0035] The further advantages of the above-mentioned design are: by setting up the blocking component, not only can the spray head 15 intermittently contact the patient's skin for wiping, but the cleaning solution can also flow out intermittently at the same time. The crossbar 34 pushes the sealing disc 35 to intermittently open or close the liquid outlet channel, realizing the pulse spray of the cleaning solution, avoiding continuous large water flow impacting the skin, reducing discomfort while ensuring the effect of clearing secretions. In addition, during the repeated movement of the piston disc 33, the rubber convex pad 42 can also be bulged, which can play a role in wiping the skin surface and massaging to promote local blood circulation.

[0036] Example 3, referring to Figures 1-8 An auxiliary device for perineal care, comprising a fluid storage cylinder 1, and further comprising: A cleaning facility that sprays cleaning solutions onto a patient's skin; The cleaning mechanism includes a top cover 11 threadedly connected to the top of the liquid storage cylinder 1. A micro pump 12 is fixedly installed on the top of the top cover 11. The outlet end of the micro pump 12 is connected to a three-way pipe 10. The inlet end of the micro pump 12 is connected to an inlet pipe 17. One end of the three-way pipe 10 is connected to an outlet pipe 13. The end of the outlet pipe 13 away from the three-way pipe 10 is connected to a connecting pipe 14. One end of the connecting pipe 14 is provided with a spray head 15. The outer surface of the spray head 15 is provided with spray holes 16. Adjustment mechanism, used to make the spray head 15 intermittently contact the patient's skin.

[0037] Furthermore, the piston tube 31 is provided with an auxiliary mechanism for wiping secretions. The auxiliary mechanism includes an air outlet hose 41 that is connected to the piston tube 31, a rubber convex pad 42 that is connected to the outer surface of the spray head 15, and the end of the air outlet hose 41 away from the piston tube 31 that is connected to the spray head 15.

[0038] When the piston disc 33 moves in the piston tube 31 toward the spray head 15, it compresses the gas between the piston disc 33 and the fixed disc 32. Since the exhaust hose 41 connects the piston tube 31 and the spray head 15, the compressed gas enters the spray head 15 from the exhaust hose 41 and is connected to the spray head 15 through the rubber convex pad 42. After entering the spray head 15, the gas enters the rubber convex pad 42, causing the rubber convex pad 42 to bulge.

[0039] The further advantage of the above is that by repeatedly bulging and shrinking the rubber pad 42, when the rubber pad 42 is bulging, it can gently wipe away secretions on the skin surface. Combined with water rinsing, the cleaning effect is enhanced. Moreover, the rubber material is soft and skin-friendly, avoiding damage to sensitive skin. When the rubber pad 42 shrinks, the secretions on its surface can be shaken off more easily, making it convenient for the next wiping.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
