Description

A pressure-regulating irrigation therapy device for clinical gynecology Technical Field

[0001] This invention relates to the field of pressure-controlled irrigation, specifically to a pressure-controlled irrigation treatment device for gynecological clinical use. Background Technology

[0002] In gynecological clinical diagnosis and treatment and postoperative care, irrigation therapy is a commonly used basic procedure. It is widely used as an adjunct treatment for inflammations such as vaginitis, cervicitis, and pelvic inflammatory disease; for cleaning and caring for wounds after cervical conization and hemorrhoid surgery; and for local care of conditions such as vulvar eczema and vulvitis in infants and young children. Its core purpose is to achieve targeted drug delivery to lesions, wound cleaning and drainage, and removal of stubborn secretions through precise rinsing or cleaning, thereby ensuring the treatment effect and postoperative recovery process.

[0003] However, existing equipment generally uses traditional water pumps to pressurize and deliver medication, with pressure adjustment relying on manual operation. Specifically, medical staff must adjust the pressure by rotating knobs and other components based on clinical experience. This not only results in slow response times and an inability to achieve immediate and precise pressure control, but also easily leads to over- or under-adjustment due to operational errors. In practical applications, excessive pressure creates a strong impact force on the medication flow, easily causing secondary irritation or damage to the patient's delicate vaginal mucosa, post-cervical surgery wounds, and other areas, leading to discomfort such as pain and bleeding. This problem is particularly pronounced in scenarios with high pressure sensitivity, such as postpartum vulvar care and infant vulvitis care. Insufficient pressure, on the other hand, fails to effectively remove stubborn secretions from the perianal folds and residual tissue after cervical conization, directly affecting the cleaning effect and medication penetration efficiency.

[0004] Meanwhile, existing irrigation therapy equipment has a narrow scope of application, making it difficult to match the diverse lesion application scenarios in gynecological clinical practice. Gynecological lesions are complex, and the location, morphology, severity, and individual patient differences of different lesions all place varying demands on irrigation methods and pressure parameters. However, existing equipment mostly offers a single irrigation mode, lacking flexible mode switching capabilities, and has a limited pressure adjustment range. This prevents personalized irrigation parameter adaptation for different lesion scenarios, resulting in less than ideal effects in complex scenarios such as drug penetration in chronic pelvic inflammatory disease, postoperative drainage of perianal abscesses, and cleaning of vulvar fungal infections. This limits its widespread application in gynecological clinical practice. Therefore, it is necessary to design a pressure-adjustable irrigation therapy device for gynecological clinical use. Summary of the Invention

[0005] Therefore, it is necessary to provide a pressure-regulating irrigation treatment device for gynecological clinical use, addressing the existing technical problems.

[0006] To address the problems of existing technologies, the present invention adopts the following technical solution: a pressure-regulating irrigation treatment device for gynecological clinical use, comprising: a constant temperature tank, a clamp for positioning the constant temperature tank, a solenoid valve for the constant temperature tank, a hose fixedly connected to the output end of the solenoid valve, a handheld spray gun for the end of the hose away from the constant temperature tank; a pulse valve and a speed regulating valve for the end of the handheld spray gun near the hose, a switching mechanism for selectively controlling the pulse valve or the speed regulating valve to be individually activated; a dual-tube nozzle for the end of the handheld spray gun away from the hose, the two output ends of the dual-tube nozzle being respectively connected to a beam nozzle and an atomizing nozzle, a blocking mechanism for selectively blocking one of the branch pipes to achieve individual output switching of the beam nozzle or the atomizing nozzle.

[0008] Furthermore, a temperature sensor is installed on the side of the pressure sensor near the dual-tube nozzle. The detection end of the temperature sensor is connected to the flow channel of the handheld spray gun, and the temperature sensor is used to detect the temperature of the medium in the flow channel of the handheld spray gun.

[0009] Furthermore, a main pipe is provided on the side of the hose closest to the handheld spray gun. The side of the main pipe closest to the handheld spray gun is connected to the input end of the pulse valve and the input end of the speed control valve, respectively. The side of the main pipe furthest from the handheld spray gun is connected to the hose. The switching mechanism is connected to the main pipe. A secondary pipe is provided on the side of the pulse valve and the speed control valve closest to each other. The two sides of the secondary pipe are connected to the output end of the pulse valve and the output end of the speed control valve, respectively. The end of the secondary pipe closest to the handheld spray gun is connected to the flow channel of the handheld spray gun.

[0010] Furthermore, the switching mechanism includes a stop bolt that is slidably connected to the main pipe along the same axis. One end of the stop bolt is rotatably connected to a screw, and the end of the main pipe near the screw is fixedly connected to a threaded sleeve. The screw and the threaded sleeve are threadedly connected.

[0011] Furthermore, a bellows is provided at one end of the stop bolt near the threaded sleeve. The bellows is coaxially sleeved on the outside of the screw rod, with one end of the bellows fixed to the threaded sleeve and the other end fixed to the stop bolt.

[0012] Furthermore, a sealing ring is coaxially fixed to the outside of the bolt, and the sealing ring is interference-fitted to the inner wall of the main pipe.

[0013] Furthermore, a guide pin is coaxially fixed to the end of the stop bolt away from the screw sleeve, and a guide sleeve is coaxially keyed to the guide pin. The end of the guide sleeve away from the stop bolt is fixed to the end of the main pipe.

[0014] Furthermore, the sealing mechanism includes a rotating shaft rotatably connected to the middle of the dual-tube nozzle. A turntable is fixedly connected to the end of the rotating shaft near the handheld spray gun.

[0015] Furthermore, a bottom ring is fixed to one end of the dual-tube nozzle near the adjusting plate. The bottom ring has two limiting holes arranged at equal angles along the circumference. Two pins are fixed to one side of the adjusting plate near the bottom ring in an equal angle arrangement along the circumference. The adjusting plate inserts the pins into the limiting holes under the action of the tension spring.

[0016] The beneficial effects of this invention compared to existing technologies are as follows: Firstly, this device achieves stable media delivery through a peristaltic pump, collects pressure data in real time using a pressure sensor, and achieves precise pressure fine-tuning with a speed regulating valve, replacing the traditional manual pressure adjustment method.

Secondly, this device achieves flexible switching between continuous irrigation and pulse irrigation modes through a switching mechanism. Combined with the switchable design of the jet nozzle and atomizing nozzle, it forms four core irrigation modes, solving the problem of the narrow applicability of traditional equipment. Firstly, it addresses the issue of limited operating modes by precisely adapting irrigation parameters and output formats to different lesion types, such as localized vaginal lesions, post-cervical surgery wounds, perianal abscesses, and vulvar eczema, as well as different populations, including adults and infants. It achieves ideal results in complex scenarios such as drug penetration for chronic pelvic inflammatory disease and post-hemorrhoid surgery cleaning, enhancing the device's clinical application value. Secondly, this device utilizes a threaded transmission switching mechanism and a limit-locking sealing mechanism to achieve rapid and precise switching between irrigation modes and output formats. It is convenient to operate and highly stable.

[0019] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0020] Referring to Figures 1 to 10, a pressure-regulating irrigation treatment device for gynecological clinical use includes: a constant temperature tank 1, a clamp 2 for positioning the constant temperature tank 1, a solenoid valve 6 for the constant temperature tank 1, a hose 3 fixedly connected to the output end of the solenoid valve 6, a handheld spray gun 8 for the end of the hose 3 away from the constant temperature tank 1; a pulse valve 9 and a speed regulating valve 10 for the end of the handheld spray gun 8 near the hose 3, a switching mechanism 13 for the side of the pulse valve 9 and the speed regulating valve 10 near the hose 3, the switching mechanism 13 for selectively controlling the pulse valve 9 or the speed regulating valve 10 to be turned on individually; a dual-tube nozzle 21 for the end of the handheld spray gun 8 away from the hose 3, the two output ends of the dual-tube nozzle 21 being connected to a beam nozzle 22 and an atomizing nozzle 23 respectively, a blocking mechanism 24 for the internal junction of the dual-tube nozzle 21, the blocking mechanism 24 for selectively blocking one of the branch pipes to achieve individual output switching of the beam nozzle 22 or the atomizing nozzle 23.

[0021] During operation, the thermostatic tank 1 stores the medium, which is then delivered to the handheld spray gun 8 via the hose 3 after being controlled by the solenoid valve 6. The spray gun integrates a pulse valve 9, a speed control valve 10, and a switching mechanism 13. Medical staff can switch between continuous flushing mode and pulse flushing mode through the switching mechanism 13. The dual-tube nozzle 21 connects the jet nozzle 22 and the atomizing nozzle 23. Medical staff can switch between point spraying and surface spraying output modes through the blocking mechanism 24 set in the middle of the dual-tube nozzle 21. During operation, medical staff can coordinate the switching mechanism 13 and the blocking mechanism 24 to form different flushing modes. The flushing pressure can be flexibly adjusted according to different lesion sites, tissue tolerance, and nursing needs. With four core combined flushing modes, it is suitable for different lesion types, nursing scenarios, and different groups such as adults and infants. It has the advantages of targeted precision, pressure controllability, and gentle comfort, which can avoid the impact damage to the wound caused by uneven flushing pressure in traditional flushing and improve the diagnosis and treatment effect.

[0022] Specifically, the application methods are as follows: Spot spray combined with continuous rinsing allows for adjustment of pressure to a gentle level based on the tolerance of the lesion. It is suitable for local vaginal lesions and post-cervical surgery wounds, enabling targeted drug delivery for vaginitis and cervicitis, and precise cleaning after cervical conization. The gentle pressure combined with continuous immersion is shock-free. Spot spray combined with pulse rinsing allows for targeted adjustment of pulse pressure to enhance drug penetration. It is suitable for deep vaginal lesions and perianal wounds, aiding in drug penetration for chronic pelvic inflammatory disease and post-operative drainage of perianal abscesses. The pulse pressure is controllable, and the spot spray targets and avoids the wound. Atomized facial spray combined with continuous rinsing, adjustable to a low-pressure mode, is suitable for the care of delicate areas. It is suitable for vulvar, postpartum, and pediatric vulvar care, cleaning vulvar eczema, gentle cleaning of large post-operative areas, and vulvitis in infants and young children. It provides wide coverage without friction and gentle pressure. Atomized facial spray combined with pulse rinsing allows for adjustment of pulse pressure to clean stubborn dirt. It is suitable for cleaning stubborn secretions around the anus and vulva, and can be used for post-hemorrhoid surgery cleaning and vulvar fungal infection care. The pulsed atomization flow has no dead angles, and the pressure is controllable to avoid damage.

[0023] To achieve a constant pressure of the rinsing medium, the following features are specifically designed: As shown in Figures 1 and 2, a peristaltic pump 5 is installed on the side of the solenoid valve 6 near the thermostatic tank 1. The input end of the peristaltic pump 5 is connected to the thermostatic tank 1, and the output end is connected to the input end of the solenoid valve 6. A pressure sensor 4 is installed in the middle of the handheld spray gun 8. The detection end of the pressure sensor 4 is connected to the flow channel of the handheld spray gun 8. The pressure sensor 4 is used to detect the pressure of the medium in the flow channel of the handheld spray gun 8.

[0024] The peristaltic pump 5 creates negative pressure flow of the medium by squeezing the elastic tubing of the flexible hose 3, achieving stable and continuous delivery of the medium without direct contact. During operation, the peristaltic pump 5 exhibits strong delivery stability, effectively avoiding pressure fluctuations caused by traditional water pump pressurization, thus laying the foundation for precise pressure regulation. Furthermore, the peristaltic pump 5, in conjunction with the speed control valve 10, enables coordinated fine-tuning of flow rate and pressure, replacing manual pressure adjustment and improving efficiency and accuracy. In addition, the peristaltic pump 5, in conjunction with the pressure sensor 4, collects real-time pressure data within the flow channel of the handheld spray gun 8, providing precise data for pressure control and further ensuring pressure stability, avoiding pressure fluctuations caused by manual adjustment.

[0025] In order to monitor the temperature of the rinsing medium in real time, the following features are also set: As shown in Figure 1, a temperature sensor 7 is set on the side of the pressure sensor 4 near the dual-tube nozzle 21. The detection end of the temperature sensor 7 is connected to the flow channel of the handheld spray gun 8. The temperature sensor 7 is used to detect the temperature of the medium in the flow channel of the handheld spray gun 8.

[0026] In addressing the significant differences in the sensitivity of different groups to the temperature of the irrigation medium in gynecological clinical practice, especially for vulnerable groups such as infants and postpartum patients, the temperature sensor 7 can monitor the temperature of the solution in real time, avoiding additional irritation to the patient's mucous membranes and wounds due to excessively high or low temperatures, and ensuring the gentleness and comfort of the irrigation process.

[0027] To achieve the switching between pulse valve 9 and speed control valve 10, the following features are specifically provided: As shown in Figures 5 and 6, a main pipe 11 is provided on the side of the hose 3 near the handheld spray gun 8. The side of the main pipe 11 near the handheld spray gun 8 is connected to the input end of pulse valve 9 and the input end of speed control valve 10, respectively. The side of the main pipe 11 away from the handheld spray gun 8 is connected to the hose 3. The switching mechanism 13 is connected to the main pipe 11. A secondary pipe 12 is provided on the side of pulse valve 9 and speed control valve 10 that are close to each other. The two sides of the secondary pipe 12 are connected to the output end of pulse valve 9 and the output end of speed control valve 10, respectively. The end of the secondary pipe 12 near the handheld spray gun 8 is connected to the flow channel of the handheld spray gun 8.

[0028] To meet the requirements of stable switching between two flushing modes and smooth media delivery, the diversion and convergence design of the main pipe 11 and the auxiliary pipe 12 ensures that when the switching mechanism 13 controls the pulse valve 9 or the speed regulating valve 10 to be turned on, the media will not leak or the delivery will be interrupted, thus ensuring the stable operation of both continuous flushing and pulse flushing modes and adapting to the flushing needs of different lesions.

[0029] To supplement the specific structure of the switching mechanism 13, the following features are also provided: As shown in Figures 5 and 7, the switching mechanism 13 includes a stop bolt 17 that is slidably connected to the main pipe 11 along the same axis. One end of the stop bolt 17 is rotatably connected to a screw 15. The end of the main pipe 11 near the screw 15 is fixedly connected to a threaded sleeve 14. The screw 15 and the threaded sleeve 14 are threadedly connected.

[0030] In terms of improving the accuracy and ease of operation of switching flushing modes, the screw-driven plug 17 adjustment structure can achieve linear and precise control. Medical staff can smoothly drive the plug 17 to slide by rotating the screw 15, accurately blocking the input end of one of the valves, realizing reliable switching between the two flushing modes and avoiding the operational errors of traditional switching methods.

[0031] In order to protect the screw 15 and prevent the flushing medium from being contaminated, the following features are also provided: As shown in Figure 7, a bellows 16 is provided at one end of the stop bolt 17 near the screw sleeve 14. The bellows 16 is coaxially sleeved on the outside of the screw 15. One end of the bellows 16 is fixedly connected to the screw sleeve 14, and the other end is fixedly connected to the stop bolt 17.

[0032] In ensuring the hygiene of the equipment and the stability of the screw 15 mechanism, the bellows 16 can isolate the screw 15 from the flushing medium, preventing the medium from splashing or penetrating to the mating surface of the screw 15 and the screw sleeve 14, causing pollution or corrosion. At the same time, it prevents dust and impurities in the clinical environment from entering the transmission mechanism, affecting the switching accuracy, and extending the service life of the equipment.

[0033] To prevent the flushing medium from flowing to the other side of the plug 17, the following features are provided: as shown in Figure 7, a sealing ring 20 is coaxially fixed to the outside of the plug 17, and the sealing ring 20 is interference-fitted to the inner wall of the main pipe 11.

[0034] Regarding the issue of enhancing the sealing of the flow channel and preventing media leakage, the interference fit between the sealing ring 20 and the inner wall of the main pipe 11 ensures that when the plug 17 blocks the input end of any valve, the media in the flow channel will not leak from the gap between the plug 17 and the main pipe 11. This ensures the stability of the flushing pressure and prevents the leaked media from polluting the clinical environment or causing additional irritation to patients.

[0035] In order to limit the movement of the bolt 17, the following features are also provided: as shown in Figures 6 and 7, the end of the bolt 17 away from the threaded sleeve 14 is coaxially fixed to a guide pin 18, the guide pin 18 is coaxially keyed to a guide sleeve 19, and the end of the guide sleeve 19 away from the bolt 17 is fixed to the end of the main pipe 11.

[0036] In ensuring the smooth sliding and precise switching of the stop bolt 17, the cooperation between the guide pin 18 and the guide sleeve 19 can limit the axial rotation of the stop bolt 17, ensuring that the stop bolt 17 always slides along the axis of the main pipe 11, avoiding the stop bolt 17 from deviating and causing sealing failure or inability to accurately seal the target valve port, and further improving the operational reliability of the switching mechanism 13.

[0037] To further elaborate on the specific structure of the sealing mechanism 24, the following features are also provided: As shown in Figures 3, 9, and 10, the sealing mechanism 24 includes a rotating shaft 25 rotatably connected to the middle of the dual-tube nozzle 21. A turntable 27 is fixedly connected to one end of the rotating shaft 25 near the handheld spray gun 8. The turntable 27 has an eccentrically opened through hole 28, which is connected to a branch pipe of the dual-tube nozzle 21. An adjusting plate 32 is coaxially keyed to one end of the rotating shaft 25 away from the turntable 27. A tension spring is provided at one end of the adjusting plate 32 near the dual-tube nozzle 21. The tension spring is coaxially sleeved on the outside of the rotating shaft 25. One end of the tension spring is fixedly connected to the adjusting plate 32, and the other end is fixedly connected to the dual-tube nozzle 21. A top plate 26 is provided on the side of the adjusting plate 32 away from the dual-tube nozzle 21, and the top plate 26 is fixedly connected to the rotating shaft 25.

[0038] To achieve the need for rapid and precise switching between the two types of nozzles, medical staff can rotate the adjustment disc 32 to drive the rotating shaft 25 to rotate, which in turn drives the rotating disc 27 to rotate, so as to quickly align and connect the perforation 28 with one of the branch pipes. After releasing the tension spring, the adjustment disc 32 can be reset and locked to ensure stable output after nozzle switching, adapting to different nursing scenarios of spot spraying and surface spraying.

[0039] To lock the rotating shaft 25, the following features are also provided: As shown in Figures 9 and 10, a bottom ring 30 is fixedly connected to one end of the dual-tube nozzle 21 near the adjusting plate 32. The bottom ring 30 has two limiting holes 31 arranged at equal angles along the circumferential direction. Two pins 29 are fixedly connected to one side of the adjusting plate 32 near the bottom ring 30 along the circumferential direction at equal angles. Under the action of the tension spring, the adjusting plate 32 inserts the pins 29 into the limiting holes 31.

[0040] To prevent accidental operation after nozzle switching, the engagement of pin 29 and limiting hole 31 allows for precise positioning of turntable 27 under the action of tension spring. This prevents the shaft 25 from rotating due to vibration or contact during handheld operation, ensuring stable output of the jet nozzle 22 or atomizing nozzle 23 and improving the safety and reliability of clinical operations.

[0041] The detailed working principle of this device is as follows: First, the constant temperature tank 1 stores the irrigation solution or cleaning medium suitable for clinical needs. The side clamp 2 is used to firmly position the constant temperature tank 1 to prevent the constant temperature tank 1 from shaking during equipment operation, which could cause the medium to overflow or the delivery to be unstable. Medical staff can complete the equipment debugging in advance according to the needs of the clinical irrigation scenario: by rotating the screw 15 of the switching mechanism 13, the plug 17 is driven to slide along the axis of the main pipe 11, accurately blocking the input end of the pulse valve 9 or the speed regulating valve 10, realizing the pre-selection of continuous irrigation mode or pulse irrigation mode; at the same time, the top plate 26 of the dual-tube nozzle 21 is rotated, which drives the rotating shaft 25 and the turntable 27 to rotate, so that the perforation 28 on the turntable 27 is connected to the branch pipe corresponding to the beam nozzle 22 or the atomizing nozzle 23. The tension spring pulls the turntable 27 to insert the pin 29 into the limiting hole 31 of the bottom ring 30, completing the locking of the point spray or area spray output mode.

[0042] After the equipment is started, the peristaltic pump 5 begins to work, smoothly extracting the flushing medium from the thermostatic tank 1 and delivering it to the main pipe 11 via the solenoid valve 6. The solenoid valve 6 can flexibly control the on / off of the medium delivery according to operational needs, allowing medical staff to pause the operation at any time during flushing. At this time, the pulse valve 9 or speed control valve 10 corresponding to the pre-selected mode is in the conducting state, and the medium enters the flow channel of the handheld spray gun 8 through the secondary pipe 12. The pressure sensor 4 in the flow channel collects the medium pressure data in real time. Medical staff can fine-tune the medium flow rate through the speed control valve 10 based on the pressure feedback, thereby accurately controlling the flushing pressure and avoiding excessive or insufficient pressure. The temperature sensor 7 simultaneously monitors the medium temperature to ensure that the medium temperature meets the patient's tolerance requirements, especially suitable for sensitive groups such as infants and postpartum patients.

[0043] Medical staff hold the spray gun 8 and aim it at the lesion. In continuous flushing mode, the medium is output at a uniform speed through the selected nozzle (beam nozzle 22 or atomizing nozzle 23), suitable for gentle cleaning or targeted drug delivery scenarios. In pulse flushing mode, the pulse valve 9 periodically controls the flow of the medium, forming a pulsed liquid flow, enhancing the penetration of the drug solution or the removal of stubborn dirt. During flushing, if it is necessary to switch the flushing mode or output form, the screw 15 of the switching mechanism 13 or the adjusting plate 32 of the dual-tube nozzle 21 can be rotated at any time. The guiding structure of the stop 17 and the limiting structure of the turntable 27 ensure that the switching process is smooth and accurate, without medium leakage or output interruption. After flushing, the peristaltic pump 5 and the solenoid valve 6 are turned off, and the constant temperature tank 1 and pipelines are cleaned, completing the entire flushing operation. The entire working process achieves flexible adaptation of flushing mode, output form and pressure parameters through the coordinated cooperation of various components, ensuring the accuracy, gentleness and safety of clinical flushing.

[0044] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
