Description

Technical Field

[0001] This utility model relates to the field of pressure pump technology, and in particular to a multifunctional bladder irrigation pressure pump. Background Technology

[0002] In urology and related medical practice, bladder irrigation is a widely used treatment method aimed at removing blood, mucus, stones, or other foreign bodies from the bladder and preventing infection. It is particularly important in treating urinary tract infections caused by fungi such as Candida, especially when patients have developed resistance to fluconazole or other oral antifungal medications. In these cases, local treatment with irrigation solutions containing antifungal agents (such as amphotericin B) is crucial. Furthermore, in postoperative care, the bladder is regularly cleaned with antibiotic-containing irrigation solutions to prevent infection and promote healing.

[0003] When using amphotericin B, it is generally diluted with 5% glucose injection. Care must be taken to ensure the drug concentration is correct. The injection should be performed in the dark, and the infusion should be slow, with each infusion lasting at least six hours. For continuous bladder irrigation, amphotericin B can be added to 1000 mL of sterile water for injection.

[0004] However, it has low solubility in water and its molecular structure is prone to aggregation to form micelles or precipitates. This makes it easy to produce small particles or cause turbidity when dissolved in physiological saline or water for injection. In other words, amphotericin B is difficult to dissolve in water and physiological saline.

[0005] According to Good Manufacturing Practice (GMP) and Pharmaceutics, poorly soluble drugs should be filtered after preparation to ensure the physical stability and sterility of the solution.

[0006] The book "Pharmaceutics" (published by People's Medical Publishing House) also mentions: "For poorly soluble drugs, particulate matter should be removed by aseptic filtration after preparation to ensure the clarity and sterility of the solution."

[0007] Therefore, in clinical practice, when amphotericin B is used for bladder irrigation, it is generally recommended to pre-filter it through a 0.22-micron sterile filter to reduce the risk of adverse reactions in patients.

[0008] A bladder irrigation pump is a device that helps people cleanse their bladder by injecting water or medication into the bladder using an electric pump, and then draining it out.

[0009] Instructions for use: Inject water or medication into the syringe, then connect the tubing to the syringe and the electric pump. Plug the power cord into an outlet and start the electric pump to inject the water or medication into the bladder.

[0010] To improve work efficiency, streamline workflows, and further enhance the safety of the use of drugs such as amphotericin B, it is necessary to provide a multifunctional bladder flushing pressurization pump with integrated filtration. Summary of the Invention

[0011] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a multifunctional bladder irrigation and pressurization pump.

[0012] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] A multifunctional bladder irrigation pressurizing pump includes a pump body, characterized in that: the water inlet end of the pump body is connected to a filter pipe one, the filter pipe one and the filter pipe two are connected by a fixed seat, a flow regulating mechanism is installed between the filter pipe one and the filter pipe two, a filter mechanism is installed at the water inlet end of the filter pipe two, and one end of the filter mechanism is connected to a connecting pipe.

[0014] The aforementioned filtration mechanism includes a first fixed sleeve and a second fixed sleeve. The first fixed sleeve and the second fixed sleeve are fixed to one end of the second filter pipe by bolts. Filter balls are installed inside the first fixed sleeve and the filter balls are provided with several filter holes. Filter cotton is filled inside the filter balls.

[0015] Furthermore, positioning blocks are provided on the inner sides of both the first and second fixing sleeves, and the two sets of positioning blocks are respectively inserted into the grooves on the upper and lower sides of the filter ball.

[0016] Furthermore, extension plates are provided on both sides of the aforementioned fixing sleeve one, and the extension plates extend to both sides of the fixing sleeve two.

[0017] The aforementioned flow regulation mechanism includes a filter plate located on one side of the filter pipe, and the filter plate has several filter holes covered with filter membranes.

[0018] Furthermore, the above-mentioned flow regulating mechanism also includes a filter plate two disposed on one side of the filter pipe. The filter plate two has rotating grooves on both sides. The filter plate two is rotatably connected to one side of the filter pipe through the rotating grooves, and the rotating groove on the other side is rotatably connected to a rotating ring disposed on one side of the filter plate.

[0019] The filter plate 2 has several filter holes 3 covered with filter membranes.

[0020] Furthermore, a gear ring is rotatably mounted on the outer side of the aforementioned filter plate two, and a drive wheel is rotatably mounted on the fixed base, with the drive wheel meshing with the gear ring.

[0021] Furthermore, the dimensions of filter pores two and three are identical, and the filter membrane has a precision of 0.2 micrometers.

[0022] The outer sleeve of the aforementioned filter pipe is fitted with an outer cylinder, and a heating wire is embedded inside the outer cylinder.

[0023] The advantages of this utility model are:

[0024] This invention filters the flushing fluid by installing a filter ball inside the pump's inlet pipe. This effectively intercepts large particles, sediments, or foreign objects in the flushing fluid, preventing these substances from entering the pressurizing pump or catheter and reducing the risk of blockage. The filter ball is flexibly fixed by fixing sleeve one and fixing sleeve two, facilitating its installation and removal. Filter plates one and two capture small particles that the filter ball cannot completely remove, providing an extra layer of protection to ensure the flushing fluid is as pure as possible. Higher filtration accuracy means a lower risk of infection and other complications, as even tiny contaminants can potentially cause adverse reactions or infections. The dual filtration mechanism increases system redundancy; even if one filtration stage fails, the other can compensate, reducing the probability of system failure.

[0025] This invention uses a rotating drive wheel to rotate the gear ring, causing the filter plate two to rotate. This causes the positions of filter holes two and three to be staggered. The staggered area can regulate the flow rate of the flushing fluid. At the same time, the outer cylinder and heating wire are used to heat the flushing fluid in the pipeline and maintain it within a suitable temperature range. This can greatly reduce the discomfort caused by cold liquid entering the body, which is especially important for long-term flushing processes.

[0026] The purpose of this invention is to provide a multifunctional bladder irrigation pump that can prevent insoluble particulate matter from entering the patient's body through traditional bladder irrigation pumps, thus avoiding potential adverse reactions. In particular, it avoids the situation where, for example, amphotericin B is mixed with normal saline or water for injection, producing insoluble particulate matter that enters the patient's body through a traditional bladder irrigation pump, potentially causing adverse reactions. This invention has strong practicality and wide applicability. Attached Figure Description

[0038] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0039] Please refer to Figures 1-10 This utility model provides a multifunctional bladder irrigation pressurizing pump, including a pump body 1. The water inlet end of the pump body 1 is connected to a filter pipe 2. The filter pipe 2 and the filter pipe 3 are connected by a fixing seat 16. A flow regulating mechanism is installed between the filter pipe 2 and the filter pipe 3. The flow regulating mechanism can not only fine adjust the flow rate of the irrigation fluid, but also perform secondary filtration of the irrigation fluid.

[0040] A filter mechanism is installed at the water inlet end of filter pipe 2 3, and one end of the filter mechanism is connected to the connecting pipe 15.

[0041] The filtration mechanism includes a first fixed sleeve 9 and a second fixed sleeve 10 (forming a circular tube). The first fixed sleeve 9 and the second fixed sleeve 10 are fixed to one end of the second filter pipe 3 by bolts. A filter ball 13 is installed inside the first fixed sleeve 9 and the second fixed sleeve 10. The filter ball 13 has several filter holes 14. The bolts make it easy to install and remove the filter ball 13. The size of the filter hole 14 at the water inlet end of the filter ball 13 is larger than the size of the filter hole 14 at the water outlet end. The filter ball 13 is filled with filter cotton 131. When the flushing fluid enters the filter ball 13 through the larger filter hole 14, it will retain impurities in the filter ball 13. The filter cotton 131 adsorbs the impurities, while the filtered flushing fluid passes through the smaller filter hole 14, thereby preventing impurities from entering the pressure pump or catheter and reducing the risk of blockage.

[0042] Furthermore, positioning blocks 12 are provided on the inner sides of both the first fixing sleeve 9 and the second fixing sleeve 10. The two sets of positioning blocks 12 are respectively inserted into the grooves on the upper and lower sides of the filter ball 13. The positioning of the positioning blocks 12 can improve the stability of the filter ball 13 during filtration.

[0043] like Figure 5 As shown, extension plates 11 are provided on both sides of the first fixed sleeve 9. The extension plates 11 extend to both sides of the second fixed sleeve 10. The connection between the first fixed sleeve 9 and the second fixed sleeve 10 is sealed by the extension plates 11 to prevent the flushing fluid from overflowing.

[0044] The flow regulation mechanism includes a filter plate 4 located on one side of the filter pipe 2 3, with several filter holes 17. A filter plate 5 is located on one side of the filter pipe 2, with rotating grooves 6 on both sides. The filter plate 5 is rotatably connected to one side of the filter pipe 2 via the rotating grooves 6. The filter plate 5 has several filter holes 18. The rotating groove 6 on the other side is rotatably connected to a rotating ring 21 on one side of the filter plate 4. When the filter plate 2 5 is rotated, the filter holes 17 and 18 are continuously staggered, thereby regulating the flow rate of the rinsing liquid. Since the filter holes 17 and 18 are the same size, the flow rate of the rinsing liquid is maximized when the filter holes 17 and 18 are completely overlapped. In addition, both the filter plate 4 and the filter plate 2 5 are covered with a filter membrane. The preferred filter membrane has a precision of 0.2 microns, which can capture small particulate impurities that the filter ball 13 cannot completely remove, providing an extra layer of protection to ensure that the rinsing liquid is as pure as possible.

[0045] Particulate matter trapped by filter membranes and filter balls can be further dissolved and reused in subsequent fluids.

[0046] In order to better rotate the filter plate 2 5, a gear ring 7 is rotatably arranged on the outer side of the filter plate 2 5, and a drive wheel 8 is rotatably arranged on the fixed base 16. The drive wheel 8 meshes with the gear ring 7. When the drive wheel 8 is rotated, the gear ring 7 can rotate the filter plate 2 5.

[0047] It is worth noting that an outer cylinder 19 is fitted on the outside of the filter pipe 2, and a heating wire 20 is embedded in the outer cylinder 19. After the heating wire 20 is connected to the power supply, it heats the rinsing liquid in the outer cylinder 19 and keeps it within a suitable temperature range, usually close to the human body temperature, which can greatly reduce the discomfort caused by cold liquid entering the body.

[0048] In summary, the working principle of the multifunctional bladder irrigation pressurization pump of this utility model embodiment is as follows: the irrigation fluid is first pressurized and drawn through the pump body 1, and then enters the filter pipe 2 3 equipped with filter balls 13. The filter balls 13 intercept large particulate impurities to ensure preliminary purification. The drive wheel 8 is rotated, which causes the gear ring 7 to drive the filter plate 2 5 to rotate. The staggered area of ​​the filter holes 2 17 and 3 18 is adjusted to finely adjust the irrigation fluid flow rate. The filter plates 1 4 and 2 5 can further capture small particulate impurities, providing additional filtration protection. The heating wire 20 in the outer cylinder 19 heats the irrigation fluid to maintain a suitable temperature and reduce patient discomfort. The purified and heated irrigation fluid is delivered to the patient's bladder through the pressurization pump body 1 to complete the irrigation process.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit this utility model in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
