Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and particularly relates to a bladder irrigation device for urology department. Background Art

[0002] Bladder irrigation is a simple treatment method commonly used in urology department, mainly used for treating hematuria, bladder inflammation, and after prostate and bladder surgeries. During bladder irrigation, a three-lumen catheter is mainly indwelled for the patient. One lumen of the three-lumen catheter is connected to an infusion set to flush urine into the bladder. After flushing a certain amount of liquid, the irrigation pipeline is clamped. Another lumen serves as an outlet to drain urine, and then the drainage pipeline is opened, and the liquid will gradually drain out from another outlet. This device flushes the bladder, effectively preventing blood clots and removing exudates, etc.

[0003] Existing bladder irrigation devices can effectively perform bladder irrigation. However, during the process of bladder irrigation, medical staff do not clamp the irrigation tube in time, resulting in more irrigation fluid flushing into the bladder, causing the irrigation fluid to flow back, and medical staff fail to detect this situation in time, resulting in overfilling of the bladder, bringing discomfort to the patient. Therefore, in view of the above problems, we propose a bladder irrigation device for urology department. Content of the Utility Model

[0004] In view of the above problems, the purpose of the present utility model is to provide a bladder irrigation device for urology department, which can timely remind medical staff to handle when liquid backflows in the pipeline.

[0005] To achieve the above purpose, the technical solution adopted by the present utility model is: a bladder irrigation device for urology department, including a treatment pipeline, an anti-backflow component, and a branch pipe. The treatment pipeline includes an irrigation pipe, a three-way catheter connected to the output end of the irrigation pipe, and a drainage pipe connected to the output cavity of the three-way catheter. The input end of the irrigation pipe is connected to an irrigation fluid bottle, and the output end of the drainage pipe is connected to a drainage fluid bottle. The anti-backflow component is arranged inside the irrigation pipe, and the anti-backflow component is used to prevent liquid from flowing back into the irrigation pipe. The branch pipe is connected to the irrigation pipe, and the branch pipe is located between the anti-backflow component and the output end of the irrigation pipe. A warning component is arranged inside the branch pipe, and the warning component is used to remind that the treatment pipeline is blocked.

[0006] ]>The beneficial effect of the present utility model is: through the setting of the anti-backflow component, when more irrigation fluid enters the bladder, the liquid in the bladder flows back. The anti-backflow component prevents the liquid from flowing back into the irrigation pipe. At the same time, the liquid flows back into the branch pipe, and the warning device in the branch pipe emits a warning, timely reminding medical staff to handle, and avoiding increasing the discomfort of the patient.

[0007] To prevent liquid backflow;

[0008] As a further improvement of the above technical solution: the anti-backflow component includes a sealing ring and a sealing disk, the circumferential outer wall of the sealing ring is connected to the inner wall of the flushing pipe, the sealing disk is located on the side of the sealing ring close to the output end of the flushing pipe, and a tension spring is connected between the sealing disk and the sealing ring.

[0009] The beneficial effect of this improvement is as follows: when liquid is flushed into the bladder, the sealing ring and the sealing disk are separated under the elastic action of the tension spring. At this time, the liquid enters the bladder through the gap between the sealing ring and the sealing disk through the urinary catheter. When the bladder is full, the medical staff fails to open the drainage tube in time, and the liquid in the bladder will flow back. At this time, the backflowing liquid will impact the sealing plate, causing the sealing plate to approach the sealing ring, and then the sealing plate will contact the sealing ring to seal the flushing tube and prevent the liquid from continuing to flow back into the flushing tube.

[0010] In order to remind medical staff in time;

[0011] As a further improvement of the above technical solution: the warning component includes a pressure sensor, a controller and an alarm, a sliding tube is slidably connected in the branch tube, a sliding rod is slidably connected in the sliding tube, a spring is connected between the sliding rod and the sliding tube, the pressure sensor is connected to the inner wall of the sliding tube, and the pressure sensor and the alarm are both electrically connected to the controller.

[0012] The beneficial effect of this improvement is: after the liquid flows back, the anti-backflow component prevents the liquid from flowing back into the flushing tube, but the liquid will enter the branch tube, and then the liquid inside the branch tube will resist the movement of the sliding tube. When the sliding rod touches the inner wall of one end of the branch tube, the liquid continues to resist the sliding tube. At this time, the spring is deformed, and then the sliding rod touches the pressure sensor. The pressure sensor receives the pressure signal and transmits the signal to the controller. The controller controls the alarm to sound an alarm, reminding medical staff so that medical staff can appear in time to deal with it.

[0013] To prevent blood clots from entering the interior of the branch tube;

[0014] As a further improvement of the above technical solution: a filter is provided at one end of the branch pipe close to the flushing pipe.

[0015] The beneficial effect of this improvement is that when the liquid flows back into the branch tube, the blood clots are blocked inside the flushing tube by filtering through the filter, thereby avoiding blockage inside the branch tube and avoiding affecting the use of the warning component.

[0016] To unclog the flushing pipe;

[0017] As a further improvement of the above technical solution: a connecting pipe is provided at one end of the branch pipe close to the flushing pipe, and a blocking cap is detachably connected to one end of the connecting pipe away from the branch pipe.

[0018] The beneficial effects of this improvement are as follows: During the flushing process, if the treatment flushing tube or the three-way catheter becomes blocked, a syringe is generally used for repeated aspiration. However, due to the setting of the anti-reflux component, medical staff cannot perform repeated aspiration from the flushing tube. The connecting tube can be connected to a syringe to aspirate the flushing tube and the three-way catheter, making the treatment pipeline unobstructed.

[0019] To control the volume and speed of the flushing fluid for flushing and drainage;

[0020] As a further improvement of the above technical solution: Flow regulating valves are provided on both the flushing tube and the drainage tube.

[0021] The beneficial effects of this improvement are as follows: By controlling the flow regulating valve, when the flushing fluid is used for flushing, it is controlled within a suitable speed range to avoid excessive speed and irritation to the bladder mucosa. When draining fluid is required, the flow regulating valve can control the volume and speed of drainage, avoiding excessive drainage volume or excessive speed, which may cause an increase in bladder pressure and bleeding.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be described in detail below with reference to the drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present utility model.

[0028] Such as Figures 1-4As shown in the figure, a bladder irrigation device for urology includes a treatment pipeline 1, an anti-reflux component 4, and a branch pipe 5. The treatment pipeline 1 includes an irrigation pipe 101, a three-way urinary catheter 102 connected to the output end of the irrigation pipe 101, and a drainage pipe 103 connected to the output cavity of the three-way urinary catheter 102. The input end of the irrigation pipe 101 is connected to an irrigation solution bottle 2, and the output end of the drainage pipe 103 is connected to a drainage solution bottle 3. The anti-reflux component 4 is arranged inside the irrigation pipe 101 and is used to prevent the liquid from flowing back into the irrigation pipe 101. The anti-reflux component 4 includes a sealing ring 401 and a sealing disc 402. The circumferential outer wall of the sealing ring 401 is connected to the inner wall of the irrigation pipe 101. The sealing disc 402 is located on the side of the sealing ring 401 close to the output end of the irrigation pipe 101. A tension spring 7 is connected between the sealing disc 402 and the sealing ring 401. The branch pipe 5 is communicated and arranged on the irrigation pipe 101 and is located between the anti-reflux component 4 and the output end of the irrigation pipe 101. A warning component 6 is arranged inside the branch pipe 5 and is used to remind that the treatment pipeline 1 is blocked. The warning component 6 includes a pressure sensor 601, a controller 602, and an alarm 603. A sliding pipe 9 is slidably connected inside the branch pipe 5, and a sliding rod 8 is slidably connected inside the sliding pipe 9. A spring 10 is connected between the sliding rod 8 and the sliding pipe 9. The pressure sensor 601 is connected to the inner wall of the sliding pipe 9. Both the pressure sensor 601 and the alarm 603 are electrically connected to the controller 602.

[0029] Specifically, when a large amount of liquid is flushed in and the medical staff forgets the time to clamp the irrigation pipe 101 and release the drainage pipe 103, resulting in the patient's bladder being overfilled, causing the liquid in the bladder to flow back. At this time, the liquid will enter the inside of the irrigation pipe 101 along the three-way urinary catheter 102, and then the liquid will impact the sealing disc 402. At this time, the sealing disc 402 squeezes the tension spring 7 and contacts the sealing ring 401. After the sealing ring 401 contacts the sealing disc 402, the irrigation pipe 101 is blocked, so that the liquid will not flow back into the irrigation solution bottle 2 to contaminate the irrigation solution. The refluxed liquid will enter the branch pipe 5, and then the liquid squeezes the sliding pipe 9, causing the sliding pipe 9 to drive the sliding rod 8 to move. When the sliding rod 8 touches the inner wall of one end of the branch pipe 5, the sliding pipe 9 continues to move, causing the sliding rod 8 to contact the pressure sensor 601. When the pressure sensor 601 receives the pressure signal, it transmits the signal to the controller 602, and the controller 602 controls the alarm 603 to issue an alarm, reminding the medical staff to promptly handle the situation of liquid reflux and avoid increasing the patient's discomfort.

[0030] Preferably, a filter screen 11 is provided at one end of the branch pipe 5 close to the flushing pipe 101. When the liquid flows back into the branch pipe 5, the blood clots are blocked inside the flushing pipe 101 through the filtration of the filter screen 11, avoiding blockage inside the branch pipe 5 and preventing the warning component 6 from being affected.

[0031] Preferably, a communicating pipe 12 is connected to one end of the branch pipe 5 close to the flushing pipe 101. A plugging cap 13 is detachably connected to the end of the communicating pipe 12 away from the branch pipe 5. If the flushing pipe 101 or the three-way catheter 102 becomes blocked during the flushing process, a syringe is generally used for repeated aspiration. However, due to the setting of the anti-backflow component 4, medical staff cannot aspirate repeatedly from the flushing pipe 101. The setting of the communicating pipe 12 can connect a syringe to aspirate the flushing pipe 101 and the three-way catheter 102 to keep the treatment pipeline 1 unobstructed.

[0032] Preferably, flow regulating valves 14 are provided on both the flushing pipe 101 and the drainage pipe 103. By controlling the flow regulating valves 14, the flushing liquid can be controlled within a suitable speed range during flushing to avoid irritation to the bladder mucosa caused by too fast a speed. When draining liquid is required, the flow regulating valves 14 can control the amount and speed of drainage to avoid excessive drainage volume or too fast a speed, which may cause an increase in bladder pressure and lead to bleeding.

[0033] The working principle and use process of the present invention are as follows: when using the device, when it is necessary to perform bladder irrigation on the patient, the various components should be assembled first, the three-way urinary catheter 102 should be inserted into the bladder through the urethra, and then the two input cavities and output cavities outside the three-way urinary catheter 102 should be connected to the irrigation tube 101 and the drainage tube 103 respectively, and then one end of the irrigation tube 101 should be connected to the irrigation liquid bottle 2 hung on the infusion stand, and one end of the drainage tube 103 should be connected to the drainage liquid bottle 3, and then the irrigation should be turned on. The flow regulating valve 14 on the washing tube 101 closes the flow regulating valve 14 at the upper end of the drainage tube 103, so that the washing liquid in the washing liquid bottle 2 flows into the bladder along the washing tube 101 and the three-way urinary catheter 102. Since there are many patients in the hospital, the medical staff may forget the time to stop washing, resulting in a large amount of washing liquid entering the bladder. At this time, the bladder is full and may cause liquid reflux. When the liquid refluxes, the liquid enters the washing tube 101 and then impacts the blocking disk 402. At this time, the blocking disk 40 2 squeezes the tension spring 7 and contacts the blocking ring 401. After the blocking ring 401 contacts the blocking disk 402, the flushing tube 101 is blocked, so that the liquid will not flow back into the flushing liquid bottle 2 to contaminate the flushing liquid. The refluxed liquid will enter the branch pipe 5. Then the liquid squeezes the sliding tube 9, causing the sliding tube 9 to drive the sliding rod 8 to move. When the sliding rod 8 contacts the inner wall of one end of the branch pipe 5, the sliding tube 9 continues to move, causing the sliding rod 8 to contact the pressure sensor 601. When the pressure sensor 601 receives the pressure signal, The signal is transmitted to the controller 602, and the controller 602 controls the alarm 603 to sound an alarm, reminding the medical staff to deal with the liquid reflux in time. Then the medical staff promptly opens the flow regulating valve 14 on the drainage tube 103 to drain the liquid into the drainage liquid bottle 3. Since the reflux of the liquid will drive the blood clot to move, the three-way catheter 102 and the flushing tube 101 may be blocked. At this time, the blocking cap 13 is opened, and the connecting tube 12 is connected to the syringe to suck the blood clot and release the blockage.
