Description

Integrated control method for tube cleaning and bladder cleaning using an automatic bladder cleaning device

[0001] The present invention relates to an integrated control method for tube cleaning and bladder cleaning using an automatic bladder cleaning device, and more specifically, to an integrated control method for tube cleaning and bladder cleaning using an automatic bladder cleaning device, which allows a patient or user, not a medical professional, to directly perform bladder cleaning, and which automatically controls the amount of cleaning solution injected and discharged, and the injection and discharge speed of the cleaning solution through a built-in algorithm, thereby facilitating tube cleaning (supply tube, catheter connection tube, and discharge tube) and bladder cleaning, and which enables bladder cleaning and tube cleaning (supply tube, catheter connection tube, and discharge tube) to be integrated and automatically performed, and which can be used multiple times and for a long period of time.

[0002] A continuous bladder irrigation device is a device that uses a catheter inserted through the urethra into the bladder to drain urine or blood clots, or to inject medication to cleanse the bladder. The device injects a irrigation solution into the bladder through the catheter, and the solution then cleanses the bladder and drains into a urine bag, completing the process. The device requires continuous replacement of the irrigation solution, necessitating ongoing supervision by medical staff and other personnel.

[0003] The conventional bladder washing process is described in detail with reference to the attached drawings below.

[0004] Figure 1 illustrates a conventional device for bladder irrigation.

[0005] Conventional bladder irrigation is performed by medical staff using a syringe (17) as shown in Fig. 1.

[0006] The medical staff inserts the urethral insertion part (15) of the urethral catheter (13) into the patient's urethra (12) and into the bladder (11), and then uses a syringe (17) to dip the syringe tip (16) into a cleaning solution container (19) filled with saline solution or sterile distilled water and pulls the plunger (18) to suck a certain amount into the syringe (17). Thereafter, the syringe tip (16) is connected to the connection part (14) of the urethral catheter (13) and the plunger (18) is pushed in to inject the cleaning solution in the syringe (17) into the bladder (11) through the urinary catheter (13) at a certain rate.

[0007] When the cleaning solution in the syringe (17) is completely injected into the bladder (11), the plunger (18) of the syringe (17) is pulled to withdraw the cleaning solution injected into the bladder from the bladder (11) again. The cleaning solution withdrawn from the bladder (11) in this way is the cleaning solution after washing away impurities in the bladder, and is therefore discarded in a waste container.

[0008] Bladder irrigation is a very effective method for removing impurities and blood clots in the bladder caused by urinary tract obstruction in patients. Based on this, it can be considered a major procedure for protecting the patient's health by reducing the risk of urinary tract infections.

[0009] However, the conventional method as described above must be directly performed by medical staff, and since it is performed manually, it is difficult for each medical staff to perform the washing method quantitatively and identically. In addition, the patient must travel to the hospital to wash the bladder using the conventional method and perform bladder washing periodically, which causes inconvenience.

[0010] In addition, when washing the bladder with the conventional method as described above, the amount of washing solution injected and discharged is adjusted according to the judgment of the medical staff, so if the medical staff lacks experience, the amount of washing solution injected and discharged is not properly adjusted, which causes the bladder washing to not be performed effectively, and all accessories such as syringes and tubes are used for single use, so only one intermittent bladder washing is possible, and they are discarded after one use, which causes a serious waste of resources.

[0011] The present invention has been proposed to solve the above problems, and the purpose is to provide an integrated control method for tube cleaning and bladder cleaning using an automatic bladder cleaning device that can easily clean the bladder by automatically controlling the amount of cleaning solution injected and discharged, the injection speed and discharge speed of the cleaning solution through an algorithm, and can perform bladder cleaning and tube cleaning (supply tube, catheter connection tube, and discharge tube) cleaning in an integrated manner, so that hygienic use and multiple use are possible and long-term use are possible, and bladder cleaning can be easily performed by patients or users other than medical staff.

[0012] In order to achieve the above object, according to one embodiment of the present invention, there is provided an integrated control method for tube cleaning and bladder cleaning using an automatic bladder cleaning device, which comprises: a supply tube having one longitudinal side connected to a cleaning solution container; a discharge tube having one longitudinal side connected to a drainage container; and a catheter connection tube having one longitudinal side connected to the other longitudinal side of the supply tube and the other longitudinal side of the discharge tube, and the other longitudinal side connected to a connection portion of a urethral catheter; the integrated control method comprises: a tube filling step of allowing a cleaning solution to flow through the supply tube and the discharge tube to perform tube cleaning while simultaneously filling the supply tube and the discharge tube with the cleaning solution to remove air therein; a bladder cleaning step of injecting the cleaning solution into a bladder to which the urethral catheter is connected through the supply tube and the catheter connection tube and discharging the cleaning solution containing impurities in the bladder through the catheter connection tube and the discharge tube; A tube washing step is provided for washing the supply tube, the catheter connecting tube and the discharge tube in a manner in which the washing solution is filled in the supply tube, the catheter connecting tube and the discharge tube and discharged through the discharge tube, and the tube filling step, the bladder washing step and the tube washing step are controlled to be performed continuously to form one washing cycle.

[0013] The above automatic bladder cleaning device is equipped with an electronic control unit with a built-in algorithm, and can control the automatic injection and automatic discharge of the cleaning solution, the injection amount and discharge amount of the cleaning solution, and the injection speed and discharge speed of the cleaning solution, so that the tube filling step, the bladder cleaning step, and the tube cleaning step are performed continuously to form one cleaning cycle.

[0014] Between the above tube filling step and the bladder washing step, a step of discharging residual urine inside the bladder to which the urethral catheter is connected through the catheter connecting tube and the discharge tube may be further provided.

[0015] The bladder washing step comprises: a step of repeatedly performing, for a predetermined period of time, an operation of injecting a washing solution corresponding to a first injection amount, which is a portion of a preset maximum washing solution supply amount, into a bladder to which the urethral catheter is connected, through the supply tube and the catheter connection tube, and discharging an amount of the injected washing solution through the catheter connection tube and the discharge tube; a step of injecting a second injection amount of washing solution, which is relatively greater than the first injection amount, into a bladder to which the urethral catheter is connected, through the supply tube and the catheter connection tube, at a first injection speed, and additionally injecting a third injection amount of washing solution, which is equal to the maximum washing solution supply amount minus the second injection amount, into a bladder to which the urethral catheter is connected, at a second injection speed lower than the first injection speed, wherein the second injection amount has a relatively greater injection amount than the third injection amount; A step may be provided to discharge an amount similar to the second injection amount of the washing solution containing impurities inside the bladder through the catheter connection tube and the discharge tube at a discharge rate that is the same as or similar to the first injection rate, and then additionally discharge an amount corresponding to the remainder of the washing solution containing impurities inside the bladder at a discharge rate that is the same as or similar to the second injection rate.

[0016] The bladder washing step comprises: a step of repeatedly performing, for a predetermined period of time, an operation of injecting a first injection amount of washing solution corresponding to a portion of a preset maximum washing solution supply amount into the bladder to which the urethral catheter is connected through the supply tube and the catheter connection tube, and discharging the amount of the injected washing solution through the catheter connection tube and the discharge tube; a step of repeatedly performing, for a predetermined period of time, an operation of additionally injecting a third injection amount of washing solution, which is relatively smaller than the second injection amount, into the bladder to which the urethral catheter is connected through the supply tube and the catheter connection tube, and discharging the amount of the additionally injected third injection amount of washing solution, while the amount of the washing solution obtained by adding the first injection amount and the second injection amount or the amount obtained by adding the second injection amount and the third injection amount is set to be equal to or less than the maximum washing solution supply amount; A step may be provided to discharge all of the washing solution containing impurities inside the bladder at a constant speed through the catheter connecting tube and the discharge tube.

[0017] The maximum supply amount of the above detergent can be 150 to 300 ml.

[0018] The automatic bladder cleaning device may include a first peristaltic metering pump installed on the supply tube to deliver the cleaning solution in the cleaning solution container to the urethral catheter; a second peristaltic metering pump installed on the discharge tube to deliver the cleaning solution in the bladder to which the urethral catheter is connected to the drainage container; a pinch valve installed on the catheter connection tube to control the flow of the cleaning solution passing through the catheter connection tube; and an electronic control unit that performs operation control of the first peristaltic metering pump and the second peristaltic metering pump and operation control of the pinch valve.

[0019] The above automatic bladder cleaning device may further include a check valve installed on the supply tube to prevent backflow of the cleaning solution.

[0020] The above tube washing step may include a step of controlling, by control via the electronic control unit, the washing liquid in the washing liquid container to flow through the supply tube, through the pinch valve on the catheter connection tube, and to the urethral catheter connection portion, thereby filling the entire supply tube and the catheter connection tube with the washing liquid; and a step of controlling, with the pinch valve closed, the washing liquid to flow through the supply tube and the discharge tube and be discharged into the drainage container.

[0021] The above tube washing step may further include a step of removing the washing solution remaining in the supply tube, the catheter connection tube, and the discharge tube.

[0022] According to the present invention, bladder washing can be facilitated by automatically controlling the amount of washing solution injected and discharged, the injection speed and discharge speed of the washing solution through an algorithm, and bladder washing and tube washing (supply tube, catheter connection tube, and discharge tube) can be performed in an integrated manner, so that hygienic use and multiple use are possible, long-term use is possible, and bladder washing can be easily performed by patients or users who are not medical staff.

[0023] Figure 1 illustrates a conventional bladder washing device.

[0024] Figure 2 is a block diagram of an automatic bladder cleaning device according to the present invention.

[0025] Figure 3 is an operation flow chart of an integrated control method for tube cleaning and bladder cleaning using the automatic bladder cleaning device of Figure 2.

[0026] Fig. 4 is a graph of the first embodiment showing the bladder cleaning control process using the automatic bladder cleaning device of Fig. 2.

[0027] Fig. 5 is a graph of a second embodiment showing a bladder cleaning control process using the automatic bladder cleaning device of Fig. 2.

[0028] Referring to the attached drawings below, an embodiment of an automatic bladder cleaning device and a bladder cleaning control method using the same according to the present invention will be described in detail.

[0029] Figure 2 is a block diagram of an automatic bladder cleaning device according to the present invention.

[0030] As illustrated in FIG. 2, the automatic bladder cleaning device (100) according to the present invention is a device that performs tube cleaning and bladder cleaning in an integrated manner, so that it can be used by patients or other users, and can be used for a long period of time rather than for a single use.

[0031] The above automatic bladder cleaning device (100) repeats the process of injecting a cleaning solution into the patient's bladder (11) for bladder cleaning and then discharging the cleaning solution inside the bladder (11), thereby removing impurities and blood clots in the patient's bladder (11) due to urinary dysfunction. In addition, for tube cleaning performed after bladder cleaning, cleaning is performed by injecting and discharging the cleaning solution into the tube.

[0032] For this purpose, the automatic bladder cleaning device (100) according to the present invention comprises: a supply tube (110) connected to a cleaning solution container (20) at one longitudinal side (left end in FIG. 2); a discharge tube (120) connected to a drainage tank (30) at one longitudinal side (left end in FIG. 2); a catheter connection tube (130) connected to the other longitudinal side (right end in FIG. 2) of the supply tube (110) and the other longitudinal side (right end in FIG. 2) of the discharge tube (120) at one longitudinal side, and connected to a connection portion of a urethral catheter (13) at the other longitudinal side (right end in this embodiment); a first peristaltic metering pump (111) installed on the supply tube (110) to transfer the cleaning solution in the cleaning solution container (20) to the urethral catheter (13); and a first peristaltic metering pump (111) installed on the discharge tube (120). It includes a second peristaltic pump (121) that delivers the washing solution in the bladder (11) to which the urethral catheter (13) is connected to the drainage tube (30). The washing solution may include physiological saline solution or sterile distilled water.

[0033] When the first peristaltic metering pump (111) is operated for bladder washing, the washing solution in the washing solution container (20) is delivered to the urethral catheter (13) through the supply tube (110) and the catheter connection tube (130), and then injected into the bladder (11) of the patient connected (inserted) to the urethral catheter (13). At this time, since the second peristaltic metering pump (121) remains stopped, the washing solution supplied to the catheter connection tube (130) through the supply tube (110) does not flow to the second peristaltic metering pump (121) but is entirely delivered to the urethral catheter (13).

[0034] When the cleaning solution is injected into the patient's bladder (11), impurities such as sludge and blood clots in the bladder (11) are mixed with the cleaning solution. When this happens, the operation of the first peristaltic metering pump (111) is stopped and the second peristaltic metering pump (121) is started. When the first peristaltic metering pump (111) is started, the cleaning solution (more specifically, the cleaning solution mixed with impurities) in the bladder (11) is sequentially discharged into the drainage tube (30) through the urethral catheter (13), the catheter connection tube (130), and the discharge tube (120). The above-described injection and discharge of the cleaning solution may be repeated a preset number of times according to the condition of the patient's bladder (11), or the number of repetitions may be increased or decreased depending on the amount of impurities and blood clots discharged into the drainage tube (30).

[0035] At this time, it is preferable that a check valve (112) be installed on the supply tube (110) to prevent the washing liquid mixed with impurities from being delivered to the first peristaltic metering pump (111) side, thereby preventing the backflow of the washing liquid (more specifically, the flow toward the first peristaltic metering pump (111) side). The check valve (112) is a type of check valve that allows the washing liquid to flow from the first peristaltic metering pump (111) side to the catheter connection tube (130) side, but prevents the washing liquid from flowing in the opposite direction. Such a check valve is commercialized in various fields, and a detailed description thereof will be omitted.

[0036] In addition, a pinch valve (131) installed on the catheter connection tube (130) to control the flow rate of the cleaning solution passing through the catheter connection tube (130) may be further included. The pinch valve (131) is a type of valve that increases or decreases the cross-sectional area of ​​the flow path within the catheter connection tube (130), and a user can control the flow of the cleaning solution flowing along the catheter connection tube (130) by manipulating the pinch valve (131). The pinch valve (131) may be provided as a three-way valve in which the other longitudinal end of the supply tube (110), the other longitudinal end of the discharge tube (120), and one longitudinal side of the catheter connection tube (130) are connected, or may be provided as a two-way valve installed on the catheter connection tube (130).

[0037] In addition, the automatic bladder cleaning device (100) according to the present invention may be equipped with an electronic control unit (140) that automatically controls the operation of the various pumps and valves mentioned above.

[0038] The electronic control unit (140) is configured to include a pump control unit (141) that outputs operation signals of the first linked metering pump (111) and the second linked metering pump (121), a valve control unit (142) that outputs operation signals of the pinch valve (131), and an MCU (144) that controls the pump control unit (141) and the valve control unit (142), as illustrated in FIG. 2.

[0039] By the control of the electronic control unit (140), the first peristaltic pump (111) and the second peristaltic pump (121) can be controlled to transfer only a preset amount of the cleaning solution, and it is possible to transfer the cleaning solution at a preset injection speed. This also applies to the pinch valve (131), and selective control of the flow and blocking of the cleaning solution is possible by the control of the electronic control unit (140). In addition, flow rate control can also be performed by allowing the cleaning solution to flow in a desired amount as needed.

[0040] The electronic control unit (140) stores a bladder washing algorithm that can be set by a user or medical staff, and the electronic control unit (140) is configured to automatically control automatic injection and automatic discharge of the washing solution, control of the injection amount and discharge amount of the washing solution, control of the injection speed and discharge speed of the washing solution, etc., through an algorithm built into the electronic control unit. Through this, it is possible to automatically control tube washing such as a supply tube, a catheter connection tube, and a discharge tube, and to control bladder washing so that it is performed.

[0041] When the electronic control unit (140) is provided in this way, the user can precisely control the operating time of the first linked metering pump (111) and the second linked metering pump (121) and the operation of the pinch valve (131) by operating the electronic control unit (140), and can also control the operating time of each pump and valve by reserving it in advance, so there is an advantage in that the bladder (11) can be washed more conveniently.

[0042] Additionally, the electronic control unit (140) may be additionally equipped with a display unit (143) that outputs information related to the supply and discharge of the cleaning solution so that the current status of bladder cleaning can be immediately identified.

[0043] Unlike the conventional technology in which medical staff perform the work manually, the automatic bladder cleaning device (100) according to the present invention automatically controls the amount of cleaning solution injected and discharged, the injection speed and discharge speed of the cleaning solution through an algorithm built into the electronic control unit (140), thereby facilitating cleaning of tubes such as a supply tube, a catheter connection tube, and a discharge tube, and bladder cleaning. In addition, since bladder cleaning and tube cleaning can be performed in an integrated manner, there is an advantage in that multiple uses are possible and long-term use is possible.

[0044] Furthermore, by using the automatic bladder cleaning device (100) according to the present invention, even if one is not a medical professional, a patient or a non-medical user can directly clean the bladder (11), so not only can the cost and time required for bladder cleaning be reduced, but convenience is also significantly increased because bladder cleaning is possible in spaces other than hospitals.

[0045] Hereinafter, the integrated control method for tube cleaning and bladder cleaning using the automatic bladder cleaning device of Fig. 2 will be described through Figs. 3 to 5.

[0046] FIG. 3 is a flowchart of the operation of a tube cleaning and bladder cleaning integrated control method using an automatic bladder cleaning device (100) according to the present invention, FIG. 4 is a graph of a first embodiment showing a bladder cleaning control process using an automatic bladder cleaning device according to the present invention, and FIG. 5 is a graph of a second embodiment showing a bladder cleaning control process using an automatic bladder cleaning device according to the present invention.

[0047] Tube cleaning and bladder cleaning using the automatic bladder cleaning device (100) according to the present invention can be configured to automatically proceed through a pre-set and stored cleaning algorithm of the electronic control unit (140) when the user simply presses the start button. Here, settings for bladder cleaning of the patient, such as the time and amount of cleaning solution to be injected, can be performed in advance by medical staff or device experts, taking into account the patient's condition.

[0048] As illustrated in FIG. 3, the integrated washing control using the automatic bladder washing device (100) according to the present invention is performed so that a tube filling step (S110), a bladder washing step (114), and a tube washing step (S116) are performed sequentially at the start to form one washing cycle.

[0049] Here, a bladder residual urine discharge step (S112) for discharging residual urine in the bladder may be included between the tube filling step (S110) and the bladder washing step (114), but this is performed only when residual urine exists and may be omitted if discharge of residual urine is not necessary.

[0050] The above tube filling step (S110) checks whether the cleaning solution container (20) is properly mounted and allows the cleaning solution to flow through the supply tube (110) and the discharge tube (120), thereby filling the supply tube (110) and the discharge tube (120) with the cleaning solution and removing the air inside as much as possible. Here, if necessary, it is also possible to further perform the process of filling the catheter connection tube (130) with the cleaning solution through precise control.

[0051] To this end, the electronic control unit (140) controls the first peristaltic pump (111) and the second peristaltic pump (121) to operate so that the cleaning liquid in the cleaning liquid container (20) passes through the first peristaltic pump (111) and the check valve (112) on the supply tube (110) and the second peristaltic pump (121) on the discharge tube (120) to be discharged into the drainage tank (30). Through this tube filling step (S110), it is possible to remove as much air as possible from the tubes constituting the supply tube (110) and the discharge tube (120), and each tube is filled with the cleaning liquid. At this time, the cleaning solution does not flow into the catheter connection tube (130) due to blocking through the pinch valve (131), but if necessary, it may be possible to control the flow into the catheter connection tube (130) to remove air.

[0052] Here, since washing of the supply tube (110) and the discharge tube (120) may be required, a process of washing the tubes by allowing a washing liquid to flow through the supply tube (110) and the discharge tube (120) may be added before performing the tube filling step (S110) as needed.

[0053] Thereafter, the bladder residual urine discharge step (S112) is performed, but if it is determined that there is no bladder residual urine, this process may be omitted. The bladder residual urine is controlled to pass through the urethral catheter (13), the catheter connection tube (130), and the pinch valve (131) and discharged into the drainage tank (30) through the discharge tube (120). At this time, the electronic control unit (140) controls the second peristaltic metering pump (121) on the discharge tube (120) to operate and the first peristaltic metering pump (111) on the supply tube (110) to not operate, and controls the check valve (112) to prevent the residual urine from flowing into the supply tube (110) and discharge it into the drainage tank (30) through the discharge tube (120).

[0054] Thereafter, the bladder washing step (S114) for continuously washing the inside of the bladder is controlled to be performed. The bladder washing step (S114) can be controlled in various embodiments. Generally, it is known that the amount of urine in the bladder when an adult feels the need to urinate is about 200 to 250 ml, but in the present invention, it is assumed that the maximum supply amount of the washing solution injected into the bladder is 150 to 300 ml to be able to respond to various environments and various people.

[0055] And, for the bladder washing step (S114) such as automatic injection and automatic discharge of the washing solution, the electronic control unit (140) precisely controls the operation of the first peristaltic metering pump (111), the second peristaltic metering pump (121), and the pinch valve (131) according to a designated algorithm.

[0056] The first embodiment of the above bladder washing step (S114) is controlled to proceed in the initial stimulation step, the middle injection step, and the final discharge step, as shown in Fig. 4.

[0057] First, as a stimulation step, a small amount of cleaning solution corresponding to a first injection amount (for example, 10 to 45 volume% (for example, 50 ml) of the maximum cleaning solution supply amount) which is a part of a preset maximum cleaning solution supply amount (for example, 200 ml) is injected into the bladder to which the urethral catheter (13) is connected through the supply tube (110) and the catheter connection tube (130), and the operation of discharging the amount of the injected cleaning solution through the catheter connection tube (130) and the discharge tube (120) is controlled to be repeatedly performed for a certain period of time (for example, 30 to 50 seconds).

[0058] This is to stimulate impurities such as sludge or blood clots accumulated in the bladder to fall from the bottom (surface) of the bladder by floating them in the washing solution and expelling them. By repeating the stimulating action of injecting and discharging a small amount of washing solution at a constant speed, the bladder is stimulated to fall impurities such as sludge or blood clots accumulated on the bottom of the bladder. This injection and discharge action can be repeated 3 to 5 times, and the number of repetitions can be increased or decreased as needed, and the injection and discharge amount can also be adjusted.

[0059] Next, the injection step is to inject a cleaning solution corresponding to a second injection amount (e.g., 55 to 90 vol% (e.g., 150 ml) of the maximum supply amount of cleaning solution) that is relatively larger than the first injection amount into the bladder to which the urethral catheter (13) is connected at a first injection speed (e.g., 7.5 ml / sec) through the supply tube (110) and the catheter connection tube (130), and to inject a third injection amount (e.g., 45 to 10 vol% (e.g., 50 ml) of the maximum supply amount of cleaning solution) that is equal to the amount obtained by subtracting the second injection amount from the maximum supply amount of cleaning solution into the bladder to which the urethral catheter (13) is connected at a second injection speed (e.g., 2.5 ml / sec) that is lower than the first injection speed so as to inject the maximum supply amount of cleaning solution (e.g., 200 ml). Here, the second injection amount is set to have a relatively larger injection amount than the third injection amount, and the sum of the second injection amount and the third injection amount can be set to correspond to the maximum supply amount of the washing liquid.

[0060] Here, the reason for injecting the washing solution corresponding to the second injection amount at the first injection speed (e.g., 7.5 ml / sec) is to ensure that a sufficient amount of washing solution is injected to suspend impurities such as sludge separated from the bladder inner wall (surface) by the stimulation step.

[0061] And, the reason why the washing solution corresponding to the third injection amount is additionally injected into the bladder to which the urethral catheter (13) is connected at a second injection speed (e.g., 2.5 ml / sec) that is lower than the first injection speed is that the feeling of the bladder being full of urine may vary from person to person, and if the washing solution is injected all at once quickly, the patient may be surprised or feel pain. Therefore, a relatively large amount is injected at a relatively high speed at first, and a small amount is slowly injected at a low injection speed thereafter to reduce the change in feeling and allow the patient to accept it smoothly. The injection step can be performed for approximately 30 to 50 seconds and can be increased or decreased depending on the patient's condition.

[0062] Next, the discharge step proceeds in the opposite direction to the injection step.

[0063] With respect to the total injected cleaning solution containing impurities inside the bladder (e.g., 200 ml + impurities), an amount similar to the second injected amount (e.g., 55 to 90 vol% of the maximum supplied amount of the cleaning solution (e.g., 150 ml + impurities)) is discharged through the catheter connection tube (130) and the discharge tube (120) at a discharge rate that is the same as or similar to the first injection rate, and then an amount similar to the third injected amount (e.g., 45 to 10 vol% of the maximum supplied amount of the cleaning solution (e.g., 50 ml + impurities)) corresponding to the remainder of the total injected cleaning solution containing impurities inside the bladder (e.g., 200 ml + impurities) is additionally discharged at a discharge rate that is the same as or similar to the second injection rate.

[0064] The discharge phase, like the injection phase, is divided into two stages, with varying speeds. This is intended to minimize the sensation of discomfort and facilitate a smoother experience for the patient, similar to the injection phase. The discharge phase can last approximately 30 to 50 seconds, and can be increased or decreased depending on the patient's condition.

[0065] Meanwhile, the second embodiment of the bladder washing step (S114) is controlled to consist of a first stimulation step, an injection step, a second stimulation step, and a final discharge step, as shown in FIG. 5.

[0066] First, as a first stimulation step, a small amount of cleaning solution corresponding to a first injection amount (for example, 10 to 45 volume% (for example, 50 ml) of the maximum cleaning solution supply amount) which is a part of a preset maximum cleaning solution supply amount (for example, 250 ml) is injected into the bladder to which the urethral catheter (13) is connected through the supply tube (110) and the catheter connection tube (130), and the amount of cleaning solution injected is discharged through the catheter connection tube (130) and the discharge tube (120), and this operation is repeatedly performed for a certain period of time (for example, 30 to 50 seconds).

[0067] This is to stimulate impurities such as sludge or blood clots accumulated in the bladder to fall from the bottom (inner wall or surface) of the bladder, so that they float in the washing liquid and are discharged.

[0068] Accordingly, by repeatedly injecting and discharging a small amount of cleaning solution at a constant rate, the bladder is stimulated, causing impurities such as sludge and blood clots accumulated at the bottom of the bladder to fall. This injection and discharge action can be repeated 3 to 5 times, and the number of repetitions can be increased or decreased as needed, and the injection and discharge rates can also be adjusted.

[0069] Next, in the injection step, a second injection amount (for example, 55 to 90 volume% (for example, 150 ml) of the maximum supply amount of the cleaning solution (for example, 250 ml)) that is relatively larger than the first injection amount is injected into the bladder to which the urethral catheter (13) is connected at a constant speed through the supply tube (110) and the catheter connection tube (130). This is to inject a sufficient amount of the cleaning solution that can suspend impurities such as sludge separated from the inner wall of the bladder by the first stimulation step. Here, the injection step can also be controlled to be injected by dividing it into a first injection speed and a second injection speed, similar to the injection step described through FIG. 4.

[0070] Next, the second stimulation step can be performed in the same manner as the first stimulation step. In a state where the second injection amount of the cleaning solution has been injected by the injection step, a third injection amount (for example, 45 to 10 volume% (for example, 50 ml) of the maximum supply amount of the cleaning solution) that is relatively smaller than the second injection amount is additionally injected into the bladder to which the urethral catheter (13) is connected through the supply tube (110) and the catheter connection tube (130), and an amount corresponding to the third injection amount, which is the amount of the additionally injected cleaning solution, is discharged through the catheter connection tube (130) and the discharge tube (120). This operation is repeated for a certain period of time (for example, 30 to 50 seconds). This is to stimulate impurities such as sludge or blood clots accumulated in the bladder to spread evenly throughout the entire cleansing solution, thereby allowing the cleansing solution and impurities to be evenly mixed and facilitated for discharge. The above injection step and the second stimulation step can be performed for approximately 60 to 70 seconds, and can be increased or decreased as needed.

[0071] Here, the amount of the washing liquid that is the sum of the first injection amount and the second injection amount or the sum of the second injection amount and the third injection amount may be set to be equal to or less than the maximum supply amount of the washing liquid.

[0072] Finally, the discharge step is performed in the opposite direction to the injection step. That is, all of the cleaning solution mixed with impurities injected into the bladder through the supply tube (110) and the catheter connection tube (130) is discharged at a constant speed. This can be performed for approximately 20 to 30 seconds and can be increased or decreased as needed. Here, the discharge step can also be divided into two stages and discharged at different speeds, similar to the discharge step, as shown in FIG. 4.

[0073] When the bladder washing step (S114) described above is completed, the tube washing step (S116) is controlled to be performed continuously.

[0074] The above tube washing step (S116) is capable of washing the supply tube (110), the catheter connection tube (130), and the discharge tube (120) by filling the supply tube (110), the catheter connection tube (130), and the discharge tube (120) with the washing solution and then discharging the solution through the discharge tube (120).

[0075] The above tube washing step (S116) can be divided into a process of discharging urine that may remain in the catheter connection tube (130) and filling it with washing solution and a process of washing the entire tube.

[0076] First, by control through the electronic control unit (140), the cleaning solution in the cleaning solution container (20) flows through the supply tube (110), passes through the pinch valve (131) on the catheter connection tube (130), and flows to the urethral catheter (130) connection portion, thereby filling the entire supply tube (110) and the catheter connection tube (130) with the cleaning solution.

[0077] Thereafter, in order to clean the entire tube, while the pinch valve (131) is closed, the cleaning solution is allowed to flow into the supply tube (110) and the discharge tube (120) to clean the supply tube (110) and the discharge tube (120). Thereafter, the cleaning solution is controlled to be discharged into the drainage container (30). Then, while the urethral catheter (13) is separated from the automatic bladder cleaning device (100), a process of removing the residual cleaning solution inside the supply tube (110), the catheter connection tube (130), and the discharge tube (120) is added. The removal of the residual cleaning solution can be performed by injecting air into the supply tube (110), the catheter connection tube (130), and the discharge tube (120). At this time, the cleaning solution filled in the catheter connection tube (130) is emptied, thereby completing the cleaning of the catheter connection tube (130).

[0078] Thereafter, in cases where bladder washing is required, it is possible to sequentially perform tube filling (S110), bladder washing (S114), and tube washing (S116) through integrated control as described above. Accordingly, safe multiple use and long-term use are possible.

[0079] As described above, according to the present invention, bladder washing can be facilitated by automatically controlling the amount of washing solution injected and discharged, the injection speed and discharge speed of the washing solution through an algorithm, and bladder washing and tube washing (supply tube, catheter connection tube, and discharge tube) can be performed in an integrated manner, so that hygienic use and multiple use are possible and long-term use is possible, and bladder washing can be easily performed by patients or users who are not medical staff.

[0080] While the present invention has been described in detail using preferred embodiments, the scope of the present invention is not limited to the specific embodiments described above, and should be interpreted in accordance with the appended claims. Furthermore, those skilled in the art will appreciate that numerous modifications and variations are possible without departing from the scope of the present invention.
