Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a bladder floatation instrument, a placing rod, a floatation instrument component and a floatation instrument control method. Background Art

[0002] Bladder instillation therapy is a traditional treatment for non-muscle-invasive urothelial carcinoma, an adjuvant treatment method performed after surgery. This method injects drugs into the bladder, which react to the tumor and kill the remaining cancer cells through the drug's cytotoxicity or stimulation of the immune system. This adjuvant treatment is suitable for patients who have undergone total cystectomy to prevent tumor recurrence. The bladder provides an anatomical basis for the implementation of bladder instillation therapy because it has a cavity for liquid storage. At present, bladder instillation therapy requires a catheter to be inserted through the urethra to connect to the bladder in the body, and the drug is slowly injected into the bladder from outside the body, so repeated, long-term, and invasive catheterization operations are required. This catheterization operation needs to be performed every month, or even for more than a year, which makes this repetitive catheterization operation very likely to lead to postoperative complications, such as infection, bleeding, urethral stenosis, etc., and may even further cause the failure of catheter placement, resulting in the inability to persist in bladder instillation operations. The occurrence of various postoperative complications will bring great physical and psychological trauma to patients, causing patients to have negative psychology such as suspicion, pessimism, and anxiety.

[0064] The present invention provides a bladder floatation instrument for releasing drugs, which only needs to be placed in the bladder through the urethra once and then suspended in the bladder liquid. The bladder floatation instrument includes a housing 1, a drive module, a control module 2 and a power module 3. The housing 1 is provided with at least one medicine cavity 4 for built-in drugs and an air cavity for providing a suspension force for suspending the entire bladder floatation instrument in the bladder liquid. The drive module, the control module 2 and the power module 3 are all sealed in the housing 1. Among them, the drive module is used to discharge the drug from the drug cavity 4 to the outside of the housing 1 in a timed and / or quantitative manner. The control module 2 is used to control the operation of the drive module. The power module 3 is used to power the drive module. Through the above structure, a drug release bladder floatation instrument that is placed in the bladder once is designed. The bladder floatation instrument can perform multiple, timed and quantitative bladder drug release as needed, avoiding repeated, long-term and invasive catheterization operations. Specifically, based on the idea of ​​avoiding repeated catheterization operations, the specific design structure of the bladder floatation instrument can have various forms, please refer to the following embodiments.

[0065] Embodiment 1

[0066] Please refer to Figure 1 and Figure 2, a bladder floatation device for releasing drugs, comprising a housing 1, a driving module, a control module 2 and a power module 3. In order to reduce the pain and damage of urethra insertion, the overall shape of the housing 1 tends to be cylindrical, such as Figure 3As shown, its diameter is not more than 8mm and the overall length is not more than 4cm (too long a length is not easy to insert into the urethra and is easy to irritate the bladder wall). One end of the shell 1 is set as an arc surface. This end can be regarded as the head end and the other end can be regarded as the tail end. When the shell 1 passes through the urethra, the head end is located in the front. At the same time, the outer side of the shell 1 can be coated with an antibacterial, hydrophilic, and anti-adhesion coating as a whole to reduce the stimulation of the urethra when the shell 1 is inserted into the bladder. The medicine cavity 4 and the air cavity in the shell 1 are two independent cavities. The air cavity can be filled with air or some other inert gases to provide buoyancy for the entire floatation instrument. The design size of the air cavity size (i.e., the size of the buoyancy) requires that the entire floatation instrument is suspended in the urine in the bladder, or floats above the urine, so that the shell 1 will not contact the sensitive bladder triangle below the bladder, and the patient will not feel uncomfortable. At least one medicine cavity 4 is provided. The medicine cavity 4 and the air cavity can be isolated by the control module 2. The control module 2 can use an integrated circuit containing a substrate. The integrated circuit includes a wireless unit and a processing unit. The wireless unit is used to receive a control signal containing start-up instructions such as start-up time, interval time, and rotation angle of motor 8 sent by an external device of the housing 1. The processing unit is used to read the start-up instruction and control the drive module to perform corresponding actions according to the start-up instruction, so that the external device (such as a tablet, a computer or a mobile phone APP) can remotely control the drug release process of the bladder floatation instrument, so that the user or the doctor can control the dosage and administration time in real time at any time according to the progress of the disease, adverse reactions of the user, etc. The substrate is wrapped with a layer of waterproof sealing material or waterproof shell and fixed inside the housing 1, which is directly used as an isolation layer between the medicine cavity 4 and the air cavity. The air cavity is located above the substrate, and the medicine cavity 4 is located below the substrate, which improves the compactness of the internal structure layout of the housing 1. The medicine cavity 4 is set as a plurality of independent cavities according to the number of administrations or the amount of administration. This embodiment takes four medicine cavities 4 as an example. A central tube 5 is fixedly connected to the middle position of the bottom of the control module 2. Four partitions 6 are evenly fixed along its circumference on the central tube 5. The upper, lower and one end away from the central tube 5 of the four partitions 6 are connected to the inner wall of the housing 1. In this way, an independent medicine cavity 4 is formed between every two adjacent partitions 6, the control module 2 and the shell 1. The four medicine cavities 4 are of the same size and have a fan-shaped cross-section. Three of the medicine cavities 4 can be independently placed in powdered or liquid medicines, and another medicine cavity 4 can be placed in a power module 3. The power module 3 includes a battery. It is fully charged before the bladder floatation device is placed in the bladder. Three through holes 7 are provided at the tail end of the shell 1. The three through holes 7 are at the same distance from the transmission rod 9, that is, the three through holes 7 are all located on the same virtual circle. At the same time, the three through holes 7 are connected to the three medicine cavities 4 containing medicines in a one-to-one correspondence. It is worth mentioning that the through hole 7 is set as large as possible without interfering with other structures to facilitate the passage of medicines or urine. Two sensing electrodes 14 close to each other are also provided in each medicine cavity 4 containing medicines. The two sensing electrodes 14 are distributed up and down and fixed on the inner wall of the shell 1.The two sensing electrodes 14 are electrically connected to the control module 2. After contacting urine or liquid medicine, a connected circuit is formed between the two sensing electrodes 14 to generate a conduction signal. The conduction signal is transmitted to the control module 2 and sent to the external device through the wireless unit for analysis: if the medicine cavity 4 contains powdered medicine, when the medicine is discharged, urine will immediately enter the medicine cavity 4, thereby generating a conduction signal, which also indicates that the medicine in the medicine cavity 4 has been discharged. Whether the medicine is successfully discharged is monitored by the presence or absence of changes in the wire signal to prevent delays in the condition due to failure of the floatation device to give medicine.

[0067] The driving module includes a motor 8, a transmission rod 9 and a baffle 10. The motor 8 can be fixed above the control module 2 (i.e., in the air cavity), and the motor 8 is controlled by the control module 2 and rotates at a set angle. The motor 8 needs to use a micro motor that matches the size of the housing 1. For example, the diameter of the more mature rotor motor on the mobile phone can be controlled to be about 3mm. The output shaft of the motor 8 faces downward, and the end of the output shaft is fixed to one end of the transmission rod 9. The transmission rod 9 penetrates the control module 2 and extends into the center tube 5, and is rotatably connected to the center tube 5. The end of the transmission rod 9 away from the motor 8 is fixed to the baffle 10 in the horizontal direction. The baffle 10 is rotatably connected to the tail end of the housing 1. A part of the partition 6 here can be cut off to prevent interference with the baffle 10, or the baffle 10 can be directly embedded in the side wall of the tail end of the housing 1 for rotation. The through hole 7 is closed or opened by the continuous rotation of the baffle 10. In this embodiment, the baffle 10 is set to be fan-shaped. The transmission rod 9 is fixed at the center of the baffle 10. The fan has a gap relative to the circle. In the initial position, the gap is located below the power module 3, and the baffle 10 blocks the through hole 7 so that the medicine cavity 4 containing the medicine is in a closed state. When the gap is rotated to correspond to the through hole 7, the through hole 7 is opened. At this time, the urine in the bladder enters the medicine cavity 4 through the through hole 7 to dissolve the medicine, and the drug factor diffuses into the bladder with the flow of urine. The baffle 10 covers the through hole 7, that is, the through hole 7 is closed. The arc angle of the fan must meet: 360-360 / 4°<arc angle<360-(the angle between one of the through holes 7 and the tangent line of the center of the fan-shaped baffle 10)°, so that the baffle 10 can open each medicine cavity 4 in turn, rather than at the same time. A protrusion is set at the edge of the tail end of the shell 1 so that the tail end forms a docking slot. An annular magnet 17 is arranged inside the docking slot. The annular magnet 17 can be magnetically adsorbed with external equipment, so that the entire bladder floatation instrument can be moved and operated more conveniently.

[0068] Embodiment 2

[0069] The difference between this embodiment and the first embodiment lies in the structural design of the baffle 10, and the rest of the structural design is the same as the first embodiment. Figure 4In this embodiment, the baffle 10 is set to be circular. A through hole 21 is provided on the circular baffle 10. Since the plurality of through holes 17 are on a virtual circle, the through hole 21 can be aligned with any through hole 17 by rotation as long as it can be aligned with the other through holes 17. When the through hole 21 is aligned with the through hole 17, the medicine cavity 4 is connected with the outside of the shell 1 to start drug administration. When the through hole 21 is offset from the through hole 17, the baffle 10 closes the through hole 17, so that the medicine cavity 4 is closed with the outside of the shell 1.

[0070] Embodiment 3

[0071] The difference between this embodiment and the first embodiment lies in the structural design of the driving module, and the other structural designs are the same as those of the first embodiment. In this embodiment, each medicine cavity 4 containing medicine is provided with a driving module, such as Figure 5 and Figure 6 As shown, it includes an electromagnet 11, a permanent magnet 12 and a one-way valve 13. The electromagnet 11 is fixed at the bottom of the control module 2, and the electromagnet 11 is electrically connected to the power module 3 and is controlled by the control module 2 to generate magnetic force by the on and off of the power. The permanent magnet 12 is set in a sheet shape, and is set horizontally and sealed to slide on the inner wall of the medicine cavity 4. It should be noted that the magnetic force of the permanent magnet 12 and the magnetic force of the electromagnet 11 are mutually exclusive, that is, after the electromagnet 11 is energized to generate magnetic force, the permanent magnet 12 is pushed downward. In the initial state, the permanent magnet 12 is located in the upper area of ​​the medicine cavity 4, and the medicine cavity 4 space below the permanent magnet 12 is a medicine storage area, which is used to fill the medicine for storage. The one-way valve 13 is installed in the through hole 7, and the valve body opening direction is from the inside of the medicine cavity 4 to the outside of the medicine cavity 4. The one-way valve 13 can adopt a hard film with a cross or a rice cut. Under normal circumstances, the film is gathered together at the incision and is in a closed state. The permanent magnet 17 moves downward to push the medicine, so that after the film is squeezed by the medicine, the film is forced to open outward at the incision to form a channel, and the medicine enters the bladder through this channel. Furthermore, the middle part of the hard film is slightly raised outside the medicine cavity 4, so that the external force of the medicine cavity 4 is not easy to push it open, forming a one-way flow effect. In this embodiment, since the inside of the medicine cavity 4 is emptied by the permanent magnet 12, the two sensing electrodes 14 can detect whether the liquid medicine is discharged: if there is liquid medicine in the medicine cavity 4, when the medicine is discharged, the conduction signal disappears, which means that the medicine in the medicine cavity 4 has been successfully discharged.

[0072] Embodiment 4

[0073] Compared with the third embodiment, the present embodiment adopts the same driving module as the third embodiment, except that only one medicine cavity 4 is provided in the present embodiment, and only one corresponding through hole 7 is provided, and the rest of the structural design is the same. The battery is still installed in the medicine cavity 4. Figure 7 and Figure 8As shown, in this embodiment, there is only one medicine chamber 4, and the electromagnet 11 is also fixed at the bottom of the control module 2. The permanent magnet 12 needs to match the cross-section of the medicine chamber 4 after removing the battery, and it slides up and down in the remaining part of the entire medicine chamber 4. The permanent magnet 12 moving downward eventually pushes the medicine out of the one-way valve 13 into the bladder, so that the structure and working principle of the entire medicine chamber 4 are similar to those of a syringe, which is suitable for liquid medicines and makes the bladder floatation instrument structure more streamlined. The amount of medicine released is controlled according to the downward movement distance of the permanent magnet 12. The downward movement distance of the permanent magnet 12 can be controlled according to the repulsive force between the permanent magnet 12 and the electromagnet 11 and the duration of the repulsive force to minimize the installation of other components.

[0074] Embodiment 5

[0075] Compared with the above embodiment, the present embodiment has a correspondingly enlarged air cavity portion, and an additional camera module 15 and a light source 16 are disposed in the air cavity. The rest of the structural design is the same as the above embodiment. Fig. 9 As shown, the shell 1 is provided with an opening. The camera module 15 and the light source 16 are fixed on the control module or the inner wall of the shell 1. The lens of the camera module 15 shoots the inner wall of the bladder through the through hole. The light source 16 illuminates the shooting direction of the camera module 15 through the through hole. Both are powered by the power module 3. At the same time, the camera module 15 is connected to the external device signal through a wireless unit. The control module 2 controls the start and stop of the camera and the light source 16 according to the operating instructions of the external device, and transmits the captured image of the camera through the wireless unit. In this embodiment, a camera imaging system wirelessly connected to an external device is added to the bladder floatation instrument. The bladder tumor condition can be directly observed by changing the patient's body position, which can replace the traditional invasive cystoscopy and reduce the pain caused to the patient by cystoscopy.

[0076] Embodiment 6

[0077] Compared with the above embodiment, this embodiment makes other designs for the layout of the air cavity on the basis of the above embodiment, and the other structural designs are the same. Fig.10 As shown, the air cavity at the head end of the shell 1 is set as a semi-enclosed structure. Interlayers are set at the head end and the side of the shell 1 to form a semi-enclosed air cavity. No interlayer is set at the medicine outlet at the tail end of the shell 1 to prevent the air cavity from providing insufficient buoyancy in the shell 1 of limited size, and at the same time make the mass distribution of the shell 1 more balanced.

[0078] Embodiment 7

[0079] Compared with the first and third embodiments, the composition and control principle of the control module 2 of this embodiment are different. At the same time, the structure is simplified, and the structure related to the sensing electrode 14 is removed, and the other structural designs are the same. The control module 2 in this embodiment includes a storage unit and a processing unit. The storage unit is used to store a preset control signal. The control signal includes a start time, an interval time, a rotation angle of the baffle 10, an on / off signal of the electromagnet 11, etc. The processing unit is used to read and process the control signal. After the start time arrives, the processing unit controls the drive module to perform the corresponding action, and after the interval time arrives, the processing unit continues to control the drive module to perform the next corresponding action, such as rotating the baffle 10, the electromagnet 11 is powered on and off, etc. Compared with the schemes of interaction and real-time control with external devices in the first and third embodiments, the bladder floatation instrument is a closed-loop system as a whole, and its control logic has been preset before being placed in the bladder according to the doctor's advice or recommended usage and dosage. The bladder floatation instrument completes the bladder drug release in a timely and quantitative manner in the bladder according to the preset logic, and can be removed from the bladder when it expires.

[0080] In order to more conveniently place the above-mentioned bladder floatation device into and take it out of the bladder, the present invention also provides a placement rod for the bladder floatation device. The placement rod is detachably connected to the bladder floatation device. The diameter of the placement rod is required to meet the insertion range of the urethra. After the bladder floatation device is sent into the bladder through the urethra, it can be detached from the bladder floatation device and withdrawn from the urethra. When the bladder floatation device needs to be taken out, the placement rod can be extended into the bladder to fix the bladder floatation device, and then the bladder floatation device is taken out of the bladder through the urethra. The placement rod can have a variety of implementation methods, such as the following embodiments:

[0081] Embodiment 8

[0082] Please refer to Fig.11 and Fig.12, the placement rod includes a rod body 18 and an electromagnet 19. One end of the rod body 18 is provided with a docking head (which can be set as a columnar protrusion style) that matches the docking slot at the rear end of the shell 1. The purpose of designing the docking head and the docking slot is to play a guiding role, so that the end of the rod body 18 can correspond to the rear end of the shell 1, which is convenient for the subsequent adsorption of the electromagnet 19. The electromagnet 19 is set on the docking head. The end of the rod body 18 away from the docking head is provided with a corresponding power supply and a switch. The opening and closing of the electromagnet 19 is controlled by the switch. When the bladder floatation instrument is placed, the electromagnet 19 is turned on first. The electromagnet 19 generates a magnetic force to adsorb the annular magnet 17 in the docking slot. At this time, the bladder floatation instrument and the end of the rod body 18 are relatively fixed, which is convenient for using the placement rod to send the bladder floatation instrument into the bladder. After closing the electromagnet 19, the bladder floatation instrument and the placement rod are naturally separated, and the placement rod is pulled out of the urethra. Similarly, when taking out the bladder floatation device, the placement rod is inserted into the bladder, and then the electromagnet 2 19 is turned on. Through the guiding effect of the docking joint and the docking slot, the electromagnet 2 19 and the annular magnet 17 are firmly adsorbed and fixed in correspondence, so that the bladder floatation device can be taken out through the urethra through the placement rod.

[0084] Please refer to Fig.13 The storage rod in this embodiment includes a rod body 18, a clamp claw 20 installed at both ends of the rod body 18, and an operating hand piece (the operating hand piece is not shown in the figure). The clamp claw 20 is set to a scissor-type, similar to a scissors structure, and is installed at the end of the rod body 18 through a connecting piece. At the same time, a spring is connected to the clamp claw 20. The function of the spring is to make the clamp claw 20 tend to be in an open state. The operating hand piece is connected to one end of the clamp claw 20 through a pull rope 22. The clamp claw 20 is closed by pulling the pull rope 22. The clamp claw 20 is also used in conjunction with the docking slot on the shell 1. At this time, a corresponding anti-slip groove can be provided in the docking slot. When the storage rod needs to be fixed to the shell 1, the clamp claw 20 extends into the docking slot, the operating hand piece is released, and the clamp claw 20 opens to both sides under the action of the spring, thereby supporting the inner wall of the docking slot. The clamp claw 20 fixes the shell 1 in the form of internal expansion. When the storage rod needs to be separated from the shell 1, the operating hand piece controls the closing of the clamp claw 20 through the pull rope 22. At this time, the clamp claw 20 can be disengaged from the docking slot, so that the clamp claw 20 is separated from the housing 1.

[0085] Embodiment 10

[0086] Please refer to Fig.14The object placement rod in this embodiment includes a rod body 18, a clamp claw 20 and a limiting sleeve 23. The clamp claw 20 is made of elastic material, and the non-clamping end of the clamp claw 20 is fixed to the end of the rod body 18. The limiting sleeve 23 is slidably arranged on the inner wall of the rod body 18. An operating structure such as a button for controlling the sliding of the limiting sleeve 23 can be provided at one end of the rod body 18 away from the clamp claw 20. At the same time, the limiting sleeve 23 is sleeved on the clamp claw 20 so that the end of the limiting sleeve 23 can be against the back of the clamp claw 20. The opening and closing degree of the clamp claw 20 is controlled by the degree of compression of the clamp claw 20 by the limiting sleeve 23. For this purpose, a corresponding clamping part can be provided at the tail end of the housing 1. The clamp claw 20 is closed to clamp the clamping part to achieve the fixation between the rod body 18 and the bladder floatation instrument. Of course, the clamping part can also be not provided, and it can be directly extended into the docking card slot in the above embodiment to be fixed by internal expansion.

[0087] Embodiment 11

[0088] Compared with the eighth, ninth and tenth embodiments, in this embodiment, an additional endoscope system is installed on the rod 18 on the basis of the above embodiments. The endoscope system can adopt a conventional optical system, such as Fig.15 As shown in the figure (the optical eyepiece is located above the rod 18), or an electronic mirror system. The electronic mirror system generally includes a CCD or CMOS lens. The lens captures the image in front, and then converts the image signal into an electrical signal, which is transmitted to the display screen along the wire. Finally, the electrical signal is processed by the image processing system built into the display screen, and a clear image is formed on the display screen for real-time playback. Fig.16 As shown (a display screen is located above the rod body 18, which is used to display the picture taken by the electronic objective lens for the convenience of the operator to watch). Regardless of the system, the objective lens is installed on the rod body 18 and is provided with an electromagnet 219 or a clamp claw 20. After the rod body 18 is placed in the floatation instrument, the situation in the bladder can be checked by the way. At the same time, be careful not to block the lens, so as to be able to see the field of view in front of the rod body 18 clearly. It should be noted that in order not to block the field of view of the endoscope system. The cross-sectional area of ​​the end of the rod body 18 should be slightly larger than the cross-sectional area of ​​the floatation instrument. If the cross-section of the end of the rod body 18 is set to be circular, the joint and the electromagnet 219 are set at the eccentric position of the end face of the connecting part, and the lens is set in the remaining position. In addition, for the clamp claw clamping structure in Example 9 and Example 10, the endoscope system also needs to be designed to avoid. For example, if the jaws 20 are arranged at the middle position of the end face of the rod body 18, the endoscope lens needs to be arranged at an eccentric position; if the jaws 20 are arranged at the eccentric position of the end face of the rod body 18, the endoscope lens can be arranged at the middle position of the end face of the rod body 18. Regardless of the layout, the purpose is to prevent the lens from being blocked.

[0089] Embodiment 12

[0090] Compared with the eighth, ninth, tenth and eleventh embodiments, in this embodiment, on the basis of the above embodiments, an additional water inlet pipe and a water outlet pipe are further arranged on the rod body 18. Fig.17 One end opening of the water inlet pipe and the water outlet pipe is located at the end of the rod body 18 close to the electromagnet 19, and the other end opening is located at the end of the rod body 18 away from the electromagnet 19. At the same time, the rod body 18 is provided with a corresponding joint and a control valve 24, so that the water inlet pipe and the water outlet pipe are connected to the external water supply equipment. When the end of the placement rod close to the electromagnet 19 is extended into the bladder, liquid is injected into the bladder and liquid flows out through the water inlet pipe and the water outlet pipe, so as to circulate and flush the inside of the bladder or cool it down.

[0091] Any bladder floatation device in embodiments 1 to 7 can be combined with any placement rod in embodiments 8 to 12. The two are combined into a bladder floatation device assembly, which can realize the whole process of bladder floatation device placement, drug release and removal through coordinated use, effectively reducing the pain of bladder treatment for patients.

[0092] Based on the bladder floatation instrument, the present invention also provides a corresponding control method of the bladder floatation instrument. The control method includes two control principles, such as the following embodiments:

[0093] Embodiment 13

[0094] The control method in this embodiment is used for the bladder floatation instrument in embodiments one to six. The control method includes the following steps: according to the user's treatment situation or whether there is an adverse reaction, the drug release time and / or drug release amount of the bladder floatation instrument in the bladder are remotely controlled in real time. Taking embodiments one, two and three as the control object, the drug release time can be controlled in real time by an external device (such as a mobile phone or a tablet) connected to the signal of the bladder floatation instrument, and the drug release time can also be timed, adjusted and other related settings by the external device. The drug release amount is realized by the number of openings of each medicine cavity 4, that is, the drug in each medicine cavity 4 is one portion. If the therapeutic effect is not enough, multiple medicine cavities 4 can be opened in the same time period to release multiple portions of medicine; if the therapeutic effect is significant and the amount of medicine needs to be reduced, the medicine cavity 4 can not be opened in the time period, or the opening of the medicine cavity 4 can be reduced to achieve the effect of reducing the amount of drug release. In this control method, we can remotely control the bladder floatation instrument placed in the bladder in real time and receive relevant information, so that the dosage and administration time can be accurately controlled in real time according to the progress of the disease or adverse reactions, so as to maximize the therapeutic effect.

[0095] Embodiment 14

[0096] The control method in this embodiment is used for the bladder floatation instrument in the seventh embodiment. The control method includes the following steps: when the start time preset on the control module 2 arrives, the drive module is started. After the drive module is started, the periodic operation of the drive module is controlled according to the cycle preset on the control module 2: the cycle includes t1 time and t2 time. When the t1 time is reached, the drive module is stopped; when the t2 time is reached, the drive module is started. Taking the structure in the second embodiment as an example, the start time is the time when the drive module is first started, which is set according to the actual situation. After the bladder floatation instrument is placed in the bladder and the start time is reached, the baffle 10 rotates, and the through hole 21 thereon rotates from the initial position (the through hole 21 is located below the power module 3) to align with the through hole 1 7, at which time the corresponding medicine cavity 4 is opened and the medicine enters the bladder. The t1 time can be set to 1 to 3s. After the drive module is started, it stops after entering the next position within 1 to 3s, that is, the through hole 21 rotates from the current position to the position aligned with the next through hole 1 7, so that the corresponding medicine cavity 4 is opened. The t2 time is the medication interval, which can generally be set to 3 to 6 weeks. After the t2 time is reached, the drive module restarts, and the subsequent cycle repeats the t1 and t2 time actions. If the structure in the third embodiment is used as the object, the corresponding control object can be replaced by the baffle 10 with the electromagnet 11. Different electromagnets 11 are started during the cycle to push all the drugs in the corresponding medicine cavity 4 into the bladder. If the structure of the fourth embodiment is used as the object, the action mode is somewhat different: the t1 time is the power-on time of the electromagnet 11, and the drug discharge amount in the medicine cavity 4 is controlled by the duration of the repulsive force. For example, the drugs in the entire medicine cavity 4 can be completely discharged in 5s (equivalent to the action time of the electromagnet 11 on the permanent magnet 12 is 5s). At this time, the t1 time can be set to 1s, that is, the electromagnet 11 is powered on for 1s, and the permanent magnet 12 generates a thrust of 1s, which can discharge one-fifth of the drug amount (due to the small overall size of the bladder floatation instrument, the reduction of the repulsive force when the permanent magnet 12 is away from the electromagnet 11 can be ignored or a different t1 time can be set). In the control method, the bladder floatation device is a closed-loop system. The control method is burned into the integrated circuit of the control module 2 in the form of program logic, and the corresponding parameters have been set according to the doctor's advice or recommended usage and dosage before being placed in the bladder. The bladder floatation device completes the bladder drug release in a timely and quantitative manner in the bladder according to the preset control method. The bladder floatation device is a disposable product, and the continuous circulation operation according to the above method does not affect the release of the drug or the environment in the bladder until the power is consumed or it is taken out of the bladder.

[0097] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0098] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
