Description

Technical Field

[0001] The present disclosure belongs to the field of bladder irrigation, and particularly relates to a bladder irrigation device. Background Art

[0002] Children with ADHD may become restless, anxious, or bored during the infusion, which can cause them to be unable to sit still and instead constantly change positions, touch objects around them, or interact with others. This behavior increases the risk of needle displacement or dislodgment during bladder irrigation, requiring reinsertion, which is unpleasant for the child and may also increase the risk of infection.

[0003] The average length of the urethra of female patients is about 4 cm. Therefore, when inserting a catheter, it is usually recommended to insert it at a depth of 4-5 cm to ensure that the balloon part of the catheter is located in the bladder. If the insertion depth is too short, the infusion tube will easily fall off when it is under pressure.

[0004] When dealing with this situation, the child's legs and feet are usually restrained, and the bladder flushing device is inserted into the patient's urethra. The base of the thigh is close to the urethra, so when the child turns over and moves around, the base of the thigh can easily squeeze out the bladder flushing plug through friction, causing the liquid to remain on the bed and contaminate the bedding and the environment around the patient. At the same time, the plug falling due to turning over will seriously damage the patient's urethra and easily cause other complications. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a bladder irrigation device, which solves the problems in the existing technology that female urinary catheters are easily removed due to their short insertion depth and contaminate bedding, and that the thighs of patients with ADHD rub against the infusion tube, thereby dragging the ureter and damaging the urethra.

[0036] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0037] According to the concept of this application, Figures 1 to 7 To describe an embodiment of the bladder irrigation device. Specifically, the bladder irrigation device is constructed as a split structure, which has three parts: wearing pants 1, supporting device 2 and eccentric wheel 4. The supporting device 2 is fixed to the patient's thigh root through the wearing pants 1. When the patient's legs move and squeeze the urethra inward, they can be supported by the supporting device 2. The infusion tube 12 can be protected by the supporting device 2, and the outer side of the infusion tube 12 on the inner side of the supporting device 2 is provided with a damping pad 10. When the infusion tube 12 is pulled outward, the damping pad 10 can fit with the infusion tube 12, increasing the resistance of the infusion tube 12 to be pulled outward, thereby reducing the damage caused by the infusion tube 12 being quickly pulled out, and the infusion tube 12 is blocked by the eccentric wheel 4 to reduce the contamination of the urethra when the irrigation liquid leaks.

[0038] Please refer to Figures 1 to 7 , a bladder irrigation device, comprising: a wearing pants 1, a supporting device 2 and an eccentric wheel 4;

[0039] Two trouser legs 101 are provided through the edge of the wearable trousers 1, and a supporting device 2 is fixed on the outside of the trouser legs 101;

[0040] The supporting device 2 includes a fixing ring 21, a supporting rod 22 and an arc-shaped plate 23. The fixing ring 21 is fixed between the two trouser legs 101. Two supporting rods 22 are fixed to the outside of the fixing ring 21, and two arc-shaped plates 23 are fixed to the ends of the two supporting rods 22 away from the fixing ring 21.

[0041] The inner side of the fixing ring 21 is provided with an infusion tube 12, and the side of the infusion tube 12 close to the wearing pants 1 is fixed with a needle 11, the side of the infusion tube 12 close to the needle 11 is bonded with a fixing ring 5, and a rubber protrusion 51 is fixed to one side of the fixing ring 5, and a plurality of hinge seats 52 are fixed to the outside of the fixing ring 5, and the outer sides of the plurality of hinge seats 52 are rotatably connected to a plurality of connecting rods 6, and the ends of the plurality of connecting rods 6 away from the hinge seats 52 are hinged with a plurality of universal joints 7, and the outer sides of the connecting rods 6 are slidably connected to the guide rods 8, and the inner side of the guide rods 8 is provided with a fixing ring 52. There is a guide groove 81 running through the guide rod 8. The sliding path of the connecting rod 6 is the same as the sliding path of the guide groove 81. The end of the guide rod 8 away from the universal joint 7 is hingedly connected to a rotating seat 82. The ends of the plurality of universal joints 7 away from the connecting rod 6 are all fixed with a damping pad 10. A conical ring 3 is fixed to one side of the fixing ring 21, and a fixing frame 31 is fixed to the end of the conical ring 3 away from the fixing ring 21. Fixed shafts 32 are fixed on both sides of the fixing frame 31. The eccentric wheel 4 is provided on the inner side of the fixed shaft 32, and the gear set 41 is fixed to the outer end of the fixed shaft 32.

[0042] The patient inserts his legs into the trouser legs 101 of the wearing pants 1. At this time, the patient's urethra leaks out of the wearing pants 1. The doctor inserts the needle 11 into the patient's urethra. At this time, the support device 2 is located at the patient's thigh root. When the patient's thigh root is clamped inward, the outer wall of the arc plate 23 fits against the side of the thigh, and the support rod 22 and the fixing ring 21 between the two arc plates 23 are both made of plastic materials with anti-deformation ability. When lying on the side, the thigh is supported by the anti-deformation ability of the support rod 22 and the fixing ring 21, thereby providing protection for the infusion tube 12, avoiding the direct squeezing of the infusion tube 12 by the patient's thigh root, resulting in poor flow of the flushing fluid and urine in the infusion tube 12, and the inability of urine to flow out normally will make the patient feel uncomfortable.

[0043] The needle 11 passes through the inner side of the fixing ring 21, and the fixing ring 5 is glued to the side close to the needle 11 by glue, so that the fixing ring 5 can move synchronously with the needle 11, and a hinge seat 52 and a rubber protrusion 51 are fixed to the outer side of the fixing ring 5. When the infusion tube 12 is dragged outward, the infusion tube 12 drives the fixing ring 5 to move outward. At this time, the multiple connecting rods 6 rotate along the hinge seat 52 and slide along the guide groove 81 to the side close to the needle 11, thereby driving the multiple damping pads 10 to move toward the side away from the needle 11 until the inner sides of the multiple damping pads 10 fit the outer wall of the infusion tube 12. By increasing the contact area between the damping pad 10 and the outer wall of the needle 11, the friction between the two is increased, thereby reducing the impact force when the infusion tube 12 is pulled out during a small range of activities;

[0044] A conical ring 3 is fixed to the side of the fixing ring 21 away from the wearing pants 1, and a fixing frame 31 is fixed to the side of the conical ring 3 away from the fixing ring 21. The eccentric wheel 4 can be supported by the fixing frame 31 and the conical ring 3 to reduce the situation in which the eccentric wheel 4 cannot rotate freely due to the pressure of the bedding. Two sets of fixed shafts 32 are fixed on both sides of the fixing frame 31, and the outer side of the fixed shaft 32 is rotatably connected to the eccentric wheel 4. When the edge of the farthest end of the eccentric wheel 4 rotates to the uppermost end, the side of the eccentric wheel 4 close to the infusion tube 12 is not The eccentric wheel 4 is in contact with the infusion tube 12, so that when the infusion tube 12 is dragged outward, it will not directly drive the rotation of the eccentric wheel 4. When the infusion tube 12 is dragged outward with a large force, the damping pad 10 is completely in contact with the outer wall of the infusion tube 12. If it still cannot prevent the infusion tube 12 from moving outward, the fixing ring 5 and the rubber protrusion 51 will continue to slide outward, so that the side of the universal joint 7 abuts the bottom of the guide rod 8, so that the guide rod 8 rotates inward along the rotating seat 82 at its upper end, thereby causing the rubber protrusion 51 to continue to slide outward until the rubber protrusion 51 is The rubber protrusion 51 passes through between the two eccentric wheels 4, and the outer edge of the rubber protrusion 51 contacts the edge of the eccentric wheel 4, so that the rubber protrusion 51 is squeezed and deformed by the two eccentric wheels 4, and is concave inward to squeeze the infusion tube 12 at the lower end of the rubber protrusion 51, so that when the rubber protrusion 51 passes through the bottom of the eccentric wheel 4, the thickness of the outer side of the infusion tube 12 increases, and the rubber material can further increase the friction between the eccentric wheel 4 and the rubber protrusion 51, thereby driving the two sets of eccentric wheels 4 to rotate, and one end of the fixed shaft 32 is fixed with a gear. The wheel enables the two eccentric wheels 4 to rotate synchronously. When the two eccentric wheels 4 are rotated to the infusion tube 12 on the side farthest from the fixed axis 32, the infusion tube 12 can be clamped, and the outflow of liquid in the infusion tube can be reduced after the needle 11 is pulled out by external force, and the pollution to the environment around the urethra can be reduced. At this time, even if the external force disappears and the infusion tube 12 hose elastically recovers, the recovery force of the infusion tube 12 is absorbed by the rubber protrusion 51 and the damping pad 10, thereby avoiding secondary damage after the infusion tube 12 recovers.

[0045] The outer side of the curved plate 23 is bonded with a leather layer 231, and the outer side of the leather layer 231 is sewn to the outer side of the trouser leg 101. The leather layer 231 is a barrier between the patient's skin and the curved plate 23, which is conducive to improving the comfort between the patient's skin and the curved plate 23, and can reduce the sharpness of the edge of the curved plate 23, so that it can better adapt to the natural curve of the human body, thereby improving the patient's wearing experience;

[0046] One end of the universal joint 7 passing through the guide groove 81 is fixed with a threaded groove 71, and the upper end of the damping pad 10 is fixed with a threaded protrusion 1001, and the threaded groove 71 is adapted to the threaded protrusion 1001. During installation, the damping pad 10 can be unscrewed along the threaded protrusion 1001 first, which is convenient for disassembling the damping pad 10. Moreover, since the damping pad 10 is close to the needle 11, when the needle 11 is pulled out, the damping pad 10 is easily stained with liquid medicine and urine. The detachable structure connected by thread allows the damping pad 10 to be cleaned and sterilized separately when the bladder flushing device needs to be recovered and cleaned, thereby reducing the sanitary dead corner area when disinfecting together.

[0047] A limiting clip 9 is fixed to the side of the support rod 22 close to the wearing pants 1, and a snap-fitting opening 91 is provided on the side of the limiting clip 9 away from the support rod 22. The inner side of the snap-fitting opening 91 is slidably connected to the limiting protrusion 131, and a limiting plate 13 is fixed to one side of the limiting protrusion 131. The limiting clip 9 and the limiting plate 13 are made of PBT plastic material. A fixing groove 232 is provided between the arc plate 23 and the fixing ring 21, and both sides of the limiting plate 13 are slidably inserted into the inner side of the fixing groove 232.

[0048] The infusion tube 12 can be passed through one side of the fixing ring 21 and wrapped around the inner side of the limiting clamp 9, and then the side of the limiting plate 13 with the limiting protrusion 131 is inserted into the inner side of the engaging opening 91, and the two ends of the limiting plate 13 are engaged in the fixing groove 232. When the patient lies on his side, the patient's thigh root clamps the two arc-shaped plates 23 inward, and the position of the fixing ring 21 is fixed. At this time, the arc-shaped plate 23 presses the limiting plate 13 inward, causing the limiting plate 13 to bend and deform inward, and the limiting protrusion 131 is inserted into the engaging opening 91. Due to the limiting protrusion The shape of 131 is conical, so that as the insertion depth of the limiting protrusion 131 increases, the locking opening 91 of the limiting clamp 9 will expand outward, so that the infusion tube 12 will slide and adjust on the inner side of the limiting clamp 9 at this time. When the patient turns over, the length of the infusion tube 12 between the urethra and the fixing ring 21 can be adaptively adjusted. The position of the urethra and the needle 11 will be changed during the turning process, and the adaptive adjustment of the infusion tube 12 during the turning process can be reduced, which can reduce the damage caused by the needle 11 being pulled outward and is conducive to further improving the patient's comfort.

[0049] The gear set 41 includes a first gear 411 and a second gear 412, and the first gear 411 and the second gear 412 are coaxially connected to the two fixed shafts 32 respectively, and the first gear 411 and the second gear 412 are meshed with each other. The first gear 411 and the second gear 412 are fixedly connected to the two fixed shafts 32 respectively, so that when the eccentric wheel 4 rotates, the two fixed shafts 32 can be driven to rotate synchronously, and the fixed shaft 32 is concentrically connected to the gear set 41, so that when the fixed shaft 32 rotates, the first gear 411 and the second gear 412 can be driven to rotate concentrically and mesh with each other. At this time, the rotation of the two eccentric wheels 4 is opposite, so that the distal edges of the two eccentric wheels 4 can simultaneously move toward the direction close to the infusion tube 12. The gear set 41 can improve the synchronization of the rotation of the eccentric wheels 4, so that the infusion tube 12 can be clamped, thereby reducing leakage.

[0050] An infusion bottle 121 is connected to the end of the infusion tube 12 away from the needle 11, and the infusion bottle 121 is hung on the upper end of the infusion stand 122. The infusion bottle 121 is hung on the infusion stand 122, and gravity is used to make the flushing fluid in the infusion bottle 121 pass through the needle 11 along the infusion tube 12 and enter the patient's body, and the flushing fluid and the contents in the bladder are drained out together through the drainage tube, thereby completing the bladder cleaning.

[0051] The side wall of the conical ring 3 is provided with a through groove 33 of the conical ring 3, and the position of the through groove 33 corresponds to the position of the eccentric wheel 4. By providing the through groove 33, interference with the movement of the eccentric wheel 4 is avoided. The conical ring 3 can both protect the eccentric wheel 4 and reduce interference with the eccentric wheel 4 through the through groove 33.

[0052] The damping pad 10 is made of silicone rubber, and the inner side of the damping pad 10 is arc-shaped, and the bending angle of the damping pad 10 matches the curvature of the infusion tube 12, which is conducive to the damping pad 10 being able to fit the infusion tube 12 when it approaches the infusion tube 12, thereby increasing the contact area between the damping pad 10 and the infusion tube 12, which is conducive to improving the friction between the two, and multiple damping pads 10 can improve the uniformity of force at the connection between them and the infusion tube 12.

[0053] The bladder irrigation device provided by the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0054] During use, the medical staff hangs the infusion bottle 121 on the upper end of the infusion stand 122, and the patient inserts his legs into the trouser legs 101 on the wearing pants 1, and passes the end of the infusion tube 12 with the needle 11 through the conical ring 3 and the fixing ring 21 in sequence, and then moves the fixing ring 5 fixed outside the infusion tube 12 and the infusion tube 12 fixed inside to the inside of the fixing ring 21, and passes the connecting rod 6 outside the fixing ring 21 through the guide groove 81, and is fixed to the outside of the universal joint 7 through the card and, then, screws the threaded groove 71 on the universal joint 7 and the threaded protrusion 1001 on the damping pad 10 together through threads, and then the doctor inserts the needle 11 into the patient's body, and inserts the infusion tube 12 between the needle 11 and the fixing ring 5 into the limiting clamp 9 through the card engagement opening 91, and the position of the infusion tube 12 between the needle 11 and the fixing ring 5 is restricted;

[0055] When the patient moves and kicks the infusion tube 12, the infusion tube 12 is pulled outward by force, thereby driving the fixing ring 5 to move outward. At this time, multiple connecting rods 6 rotate inward along the hinge seat 52, and make the connecting rods 6 and the universal joint 7 slide along the guide groove 81 toward the side close to the infusion tube 12 until the inner walls of the multiple damping pads 10 are in contact with the outer wall of the infusion tube 12. As the fixing ring 5 continues to move, the rubber protrusion 51 passes through between the two eccentric wheels 4. During the passing process, when the outer wall of the rubber protrusion 51 contacts the eccentric wheel 4, the eccentric wheel 4, the fixed shaft 32, the first gear 411 and the second gear 412 are driven to rotate synchronously, and the first gear 411 and the second gear 412 are meshed until the farthest edges of the two eccentric wheels 4 squeeze the rubber protrusion 51 and the infusion tube 12 at the same time, causing the rubber protrusion 51 and the infusion tube 12 to be compressed and deformed and flatten the infusion tube 12, thereby completely blocking the infusion tube 12 and stopping the continued flow of the flushing liquid.
