Description

Technical Field

[0001] This invention belongs to the field of bladder irrigation, and more specifically, relates to a bladder irrigation device for clinical use in urology. Background Technology

[0002] Bladder irrigation is a method that uses a urinary catheter to infuse a solution into the bladder, and then uses the siphon principle to drain the instilled fluid. Current bladder irrigation devices mainly consist of three parts: a urinary catheter, an irrigation tube, and a drainage tube. The urinary catheter is connected to both the irrigation tube and the drainage tube via a three-way connector. The procedure is as follows: the irrigation tube is connected to an irrigation bag containing the irrigation solution, and the drainage tube is connected to the drainage bag. The irrigation solution is directed through the irrigation tube to the urinary catheter, which then irrigates the bladder. After irrigation is complete, the irrigation tube is closed, and the waste fluid is drained into the drainage bag through the urinary catheter and drainage tube. However, existing bladder irrigation devices still have some shortcomings in actual operation. First, when switching between irrigation and drainage, it is usually necessary to manually turn off the switch on the irrigation tube and turn on the switch on the drainage tube. The operation steps are relatively cumbersome, especially when frequent irrigation and drainage are required, which increases the workload of medical staff. Moreover, manual operation may affect the irrigation effect due to untimely or improper operation. Second, it is difficult to precisely control the flow rate and pressure of the irrigation fluid. If the flow rate is too fast, it may cause irritation or damage to the bladder wall. If the flow rate is too slow, it may lead to incomplete irrigation. Unstable pressure may also cause patient discomfort and even lead to risks such as retrograde infection.

[0003] In view of this, the present invention is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a bladder irrigation device for clinical use in urology, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: A bladder irrigation device for clinical use in urology includes: a drug storage tank, a three-way tube, an irrigation tube, and a fixed base. The upper side of the drug storage tank is connected to a first telescopic hose. One end of the first telescopic hose passes through and is located inside the lower part of the drug storage tank. An inlet pipe and an outlet pipe are respectively provided above and below the drug storage tank. A first check valve is provided inside the first telescopic hose. One end of the first telescopic hose is connected to the tee pipe; One end of the flushing pipe is equipped with a flushing head, and the other end of the flushing pipe is connected to the three-way pipe; The fixed base is connected to one side of the medicine storage tank. A groove is provided on one side of the fixed base. A pedal is rotatably and elastically connected in the groove. A foot-operated air cylinder corresponding to the pedal is provided in the groove. The foot-operated air cylinder is connected to the medicine storage tank. The medicine storage tank is equipped with a stirring roller that rotates and engages with the pedal drive.

[0006] Optionally, the foot-operated air cylinder includes a telescopic air cylinder, a one-way valve is provided on one side of the telescopic air cylinder, a spring is fixedly connected between the pedal and the groove, and an inflation pipe connected to the telescopic air cylinder is provided inside the medicine storage tank. The telescopic air cylinder is located between the pedal and the groove.

[0007] Optionally, the air inflator is located inside one side of the medicine storage tank, and one end of the air inflator is located above the inside of the medicine storage tank.

[0008] Optionally, the bottom of the medicine storage tank is provided with an inner cavity, in which a first bevel gear fixedly connected to the stirring roller is rotatably fitted, and a second bevel gear meshing with the first bevel gear is rotatably fitted, and the second bevel gear is in transmission engagement with the pedal.

[0009] Optionally, a fixing groove is provided on one side of the groove, a first pulley is provided on one side of the second bevel gear, a second pulley is rotatably engaged in the fixing groove, a transmission belt is sleeved between the first pulley and the second pulley, and the second pulley is in transmission engagement with the pedal.

[0010] Optionally, the second pulley and the pedal are each provided with a pivot on the opposite side, and a movable rod is movably connected between the two pivots.

[0011] Optionally, a second flexible hose is connected to the three-way pipe, the second flexible hose is connected to a drainage bag, and a second check valve is installed inside the second flexible hose.

[0012] Optionally, the drainage bag is connected to a connecting tube, and an air bladder is provided on the connecting tube, with an air outlet on the air bladder.

[0013] Optionally, a support is provided on the medicine storage tank, and the flushing pipe is placed above the medicine storage tank through the support.

[0014] Optionally, a transparent observation window is provided on the outer wall of the medicine storage tank, and scale lines are provided on the transparent observation window along the vertical direction.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: A foot pedal, installed within a recessed groove, drives an air pump, inflating the medication storage tank and increasing its internal pressure. This pressure forces the flushing solution to be delivered to the flushing head via a first telescopic hose, a three-way connector, and a flushing tube, thus rinsing the bladder. Simultaneously, the pedal's engagement with a stirring roller ensures the pump rotates within the storage tank, agitating and mixing the flushing solution to ensure uniform composition and prevent sedimentation that could affect the flushing effect. This foot-operated design eliminates the need for manual squeezing or additional power equipment, freeing up the hands and allowing for initial adjustment of the flushing pressure and flow rate by controlling the pedaling force and frequency. This makes operation more convenient and flexible, especially when continuous or intermittent flushing is required, effectively reducing hand fatigue for medical personnel.

[0020] The invention will now be described in further detail with reference to the accompanying drawings.

[0021] Please see Figure 1-6 As shown, this embodiment provides a bladder irrigation device for clinical use in urology, including: a drug storage tank 1, a three-way pipe 3, an irrigation pipe 4 and a fixing base 7. A first telescopic hose 2 is connected to the upper side of the drug storage tank 1. One end of the first telescopic hose 2 passes through and is located inside the lower part of the drug storage tank 1. An inlet pipe 5 and an outlet pipe 6 are respectively provided above and below the drug storage tank 1. A first check valve is provided inside the first telescopic hose 2. One end of the first telescopic hose 2 is connected to the tee pipe 3; One end of the flushing pipe 4 is equipped with a flushing head 31, and the other end of the flushing pipe 4 is connected to the three-way pipe 3; The fixed base 7 is connected to one side of the medicine storage tank 1. A groove 8 is provided on one side of the fixed base 7. A pedal 9 is rotatably and elastically connected in the groove 8. A foot-operated air cylinder 15 corresponding to the pedal 9 is provided in the groove 8. The foot-operated air cylinder 15 is connected to the medicine storage tank 1. The medicine storage tank 1 is equipped with a stirring roller 10 that is driven by the pedal 9.

[0022] By stepping on the pedal 9 located within the groove 8, the air pump 15 is activated, inflating the medicine storage tank 1. This increases the internal pressure of the medicine storage tank 1, causing the flushing fluid within the medicine storage tank 1 to be transported to the flushing head 31 under pressure through the first telescopic hose 2, the three-way hose 3, and the flushing pipe 4, thus achieving the flushing operation of the bladder. Simultaneously, due to the transmission cooperation between the pedal 9 and the stirring roller 10, when the pedal 9 is stepped on, the stirring roller 10 is also driven to rotate within the medicine storage tank 1, stirring and mixing the flushing fluid in the tank to ensure uniform composition and prevent the flushing effect from being affected by drug sedimentation. This foot-operated design eliminates the need for medical personnel to manually squeeze or use additional power equipment. While freeing up their hands, the pressure and flow rate of the flushing fluid entering the bladder can be initially adjusted by controlling the force and frequency of stepping, making the operation more convenient and flexible. Especially when continuous or intermittent flushing is required, it can effectively reduce the hand fatigue of medical personnel.

[0023] like Figure 4-6As shown, the foot-operated air cylinder 15 of this embodiment includes a telescopic air cylinder 14. A one-way valve 16 is provided on one side of the telescopic air cylinder 14. A spring 13 is fixedly connected between the pedal 9 and the groove 8. An inflation pipe 17 connected to the telescopic air cylinder 14 is provided inside the medicine storage tank 1. The telescopic air cylinder 14 is located between the pedal 9 and the groove 8. The inflation pipe 17 is located inside one side of the medicine storage tank 1, and one end of the inflation pipe 17 is located above the inside of the medicine storage tank 1. The bottom of the medicine storage tank 1 is provided with an inner cavity 18. A first cone fixedly connected to the stirring roller 10 is rotatably fitted inside the inner cavity 18. Gear 19, a second bevel gear 20 is rotatably fitted in the inner cavity 18 and meshes with the first bevel gear 19, the second bevel gear 20 is in transmission engagement with the pedal 9; a fixed groove 22 is opened on one side of the groove 8, a first pulley 21 is provided on one side of the second bevel gear 20, a second pulley 23 is rotatably fitted in the fixed groove 22, a transmission belt 24 is sleeved between the first pulley 21 and the second pulley 23, the second pulley 23 is in transmission engagement with the pedal 9; a rotating shaft 25 is provided on the opposite side of the second pulley 23 and the pedal 9, and a movable rod 26 is movably connected between the two rotating shafts 25.

[0024] When flushing is required, medical staff step on pedal 9, which compresses spring 13 and squeezes telescopic air cylinder 14. The gas in telescopic air cylinder 14 is forced into the upper part of the medicine storage tank 1 through one-way valve 16 and air filling pipe 17. The air pressure is used to force the flushing fluid in the medicine storage tank 1 into the first telescopic hose 2. At the same time, pedal 9 drives movable rod 26 through rotating shaft 25 on one side. Movable rod 26 drives second pulley 23 in fixed groove 22 to rotate. Second pulley 23 drives first pulley 21 and second bevel gear 20 coaxial with it to rotate through transmission belt 24. The second bevel gear 20 meshes with the first bevel gear 19, thereby driving the stirring roller 10 to rotate inside the medicine storage tank 1 to stir the rinsing liquid. After releasing the pedal 9, the spring 13 returns to its original position, causing the pedal 9 to rise. The telescopic air cylinder 14 retracts under its own elasticity and draws in air from the outside through the one-way valve 16 to prepare for the next step to inflate. At the same time, the movable rod 26, the second pulley 23, the transmission belt 24, the first pulley 21, the second bevel gear 20, and the first bevel gear 19 move in opposite directions, causing the stirring roller 10 to rotate in the opposite direction, further enhancing the stirring effect and ensuring that the rinsing liquid is mixed evenly.

[0025] like Figure 2-3 As shown, in this embodiment, a second telescopic hose 28 is connected to the three-way pipe 3, a drainage bag 27 is connected to the second telescopic hose 28, and a second check valve is provided inside the second telescopic hose 28; a connecting pipe 29 is connected to the drainage bag 27, an air bag 30 is provided on the connecting pipe 29, and an air outlet is provided on the air bag 30.

[0026] In actual flushing operations, after the flushing fluid enters the bladder through the first telescopic hose 2 and the three-way tube 3, if it is necessary to drain the flushing waste fluid from the bladder, the second check valve can ensure that the waste fluid can only flow into the second telescopic hose 28 in one direction, avoiding backflow and pollution. The waste fluid enters the drainage bag 27 through the second telescopic hose 28 for collection, facilitating subsequent processing and measurement. The connecting tube 29 and the air bladder 30 connected to the drainage bag 27 play a role in auxiliary fixation and backflow prevention. When the waste fluid in the drainage bag 27 reaches a certain amount, the air bladder 30 can be squeezed to utilize the pressure difference generated by the contraction and expansion of the air bladder 30 to assist in the discharge of gas from the drainage bag 27, preventing the normal drainage of waste fluid from being affected by excessive air pressure in the drainage bag 27. The air outlet provides a channel for gas discharge, ensuring the smoothness and safety of the drainage process.

[0027] like Figure 1 As shown, in this embodiment, a support 32 is provided on the medicine storage tank 1, and the rinsing pipe 4 is placed above the medicine storage tank 1 through the support 32.

[0028] The bracket 32 ​​provides stable support for the flushing pipe 4. After the flushing pipe 4 is placed on the bracket 32, its inlet end can naturally drop below the flushing liquid surface in the medicine storage tank 1. The height and shape design of the bracket 32 ​​can ensure that the flushing pipe 4 maintains a certain curvature and height when placed.

[0029] A transparent observation window is provided on the outer wall of the medicine storage tank 1 in this embodiment, and scale lines are provided on the transparent observation window along the vertical direction.

[0030] Among these features, medical staff can clearly observe the remaining amount of flushing fluid inside the medicine storage tank 1 without opening the lid. The scale lines provide an intuitive basis for accurately reading the volume of flushing fluid, with the smallest scale value reaching 10 ml, which can meet the clinical needs for precise control of flushing fluid usage. When performing bladder irrigation, medical staff can observe the changes in the scale lines to keep track of the flushing fluid usage in real time, thereby accurately calculating the flushing volume and avoiding the impact of insufficient flushing fluid on the treatment effect or waste caused by excessive use.

[0031] To reduce the discomfort caused by cold medication entering the patient's bladder, an embodiment is provided.

[0032] In this embodiment, a heating component is installed inside the medicine storage tank 1. This heating component includes an annular heating element that is tightly attached to the inner wall of the medicine storage tank 1, and a temperature control module for controlling the heating temperature. The heating element is made of flexible silicone material, allowing it to fit tightly against the tank wall and ensure uniform heat transfer to the flushing solution. Its power is 30-50 watts, capable of heating 2000 ml of flushing solution from room temperature to a human body temperature range of 37±1℃ within 10-15 minutes. The temperature control module consists of a temperature sensor, a microprocessor, and a relay. The temperature sensor monitors the flushing solution temperature in real time and transmits the data to the microprocessor. When the temperature reaches a preset value, the microprocessor controls the relay to cut off the power. When the heating element is powered on, heating stops. If the temperature falls below the preset lower limit, the relay automatically closes to resume heating, thus achieving precise and constant temperature control of the flushing solution. Simultaneously, a temperature display screen and adjustment buttons are located on the outer wall of the medication storage tank 1. Medical staff can fine-tune the target temperature according to the patient's specific condition (e.g., adjusting it 0.5-1℃ higher in winter when the room temperature is low). The display screen shows the current medication temperature in real time, allowing medical staff to easily check it and avoid scalding the patient's bladder mucosa due to excessively high temperatures or causing bladder spasms due to excessively low temperatures. The power interface of the heating component is located on the bottom side of the medication storage tank 1 and features a waterproof design to ensure electrical safety during use.

[0033] Working principle: When medical staff need to perform bladder irrigation on a patient, they first inject an appropriate amount of irrigation fluid into the medication storage tank 1 through the inlet tube 5. The injection volume can be precisely controlled through the transparent observation window and scale lines on the outer wall of the medication storage tank 1. If the ambient temperature is low or the patient is temperature sensitive, the heating element can be activated, and a target temperature (usually 37°C) can be set. The heating element will then heat the irrigation fluid. The temperature control module monitors and maintains a stable temperature in real time. Medical staff can observe the current medication temperature through the temperature display screen. Once ready, the irrigation head 31 of the irrigation tube 4 is gently inserted into the patient's bladder. The drainage bag 27 is placed below the patient's body position. Then, medical staff step on the pedal 9 in the groove 8 of the fixing seat 7. The pedal 9 compresses the spring 13 and squeezes the telescopic air cylinder 14. The gas in the telescopic air cylinder 14 enters the upper part of the medicine storage tank 1 through the one-way valve 16 and the inflation tube 17, increasing the air pressure inside the tank. Under the action of air pressure, the flushing fluid in the medicine storage tank 1 enters the flushing tube 4 through the first telescopic hose 2 (containing a first check valve to prevent backflow) and the three-way tube 3, and finally enters the patient's bladder through the flushing head 31. At the same time, the pedal 9 drives the movable rod 26 through the rotating shaft 25. The moving rod 26 drives the second pulley 23 in the fixed groove 22 to rotate. The second pulley 23 drives the first pulley 21 and the second bevel gear 20 to rotate through the transmission belt 24. The second bevel gear 20 meshes with the first bevel gear 19, thereby causing the stirring roller 10 to rotate in the medicine storage tank 1 to stir the flushing liquid and ensure its uniform composition. When the pedal 9 is released, the spring 13 returns to its original position, causing the pedal 9 to rise. The telescopic air cylinder 14 inhales and returns to its original position, preparing for the next inflation. At the same time, the stirring roller 10 rotates in the opposite direction to further enhance the stirring effect. When it is necessary to drain the flushing waste liquid from the bladder, the waste liquid is drained under the pressure of the bladder itself. Alternatively, under the influence of body position, the fluid enters the second telescopic flexible tube 28 through the flushing head 31, flushing tube 4, and three-way tube 3 [with a second check valve to prevent backflow contamination], and finally flows into the drainage bag 27. As the waste fluid in the drainage bag 27 increases, the air bag 30 can be squeezed to help expel the gas in the bag through its pressure difference, ensuring smooth drainage. Throughout the process, medical staff can adjust the pressure and flow rate of the flushing fluid by controlling the force and frequency of stepping on the pedal 9. The support 32 provides stable support for the flushing tube 4. After the treatment, the remaining liquid in the medicine storage tank 1 can be emptied through the drain pipe 6 for cleaning and disinfection.
