Abstract
Description
Technical Field
[0001] This utility model relates to the field of urodynamic testing technology, specifically to a urodynamic testing device with an anti-reflux structure. Background Technology
[0002] Urodynamics is a science that studies the physiological processes of urine storage and voiding, as well as their functional disorders, based on the principles of fluid mechanics, combined with bioelectrophysiological methods and sensor technology. The scope of urodynamic research covers multiple aspects, including normal voiding physiology, urinary tract obstructive diseases, neurogenic bladder, non-neurogenic bladder and urethral dysfunction, enuresis, and urinary incontinence. It is divided into upper urinary tract urodynamics and lower urinary tract urodynamics based on the examination methods used. To more accurately assess a patient's bladder function and other related conditions, urodynamics requires the use of diagnostic equipment.
[0003] Common urodynamic testing equipment typically consists of an electromyography (EMG) module, a pressure module, a uroflowmetry sensor, an irrigation pump, and a catheter retractor. The EMG module records the electrical activity of the pelvic floor muscles to assess muscle function. The pressure module contains a pressure sensor to measure pressure changes in the bladder and urethra. The uroflowmetry sensor measures the uroflowmetry rate, which is the volume of urine expelled per unit time. The irrigation pump slowly infuses physiological saline into the bladder, simulating the process of urine storage in the human body.
[0004] Traditional urodynamic testing equipment suffers from reflux of fluid into the pressure transmission catheter due to increased bladder pressure during the test, leading to cross-infection and affecting the accuracy of the results. To address this issue, some urodynamic testing devices with anti-reflux structures connect an anti-reflux tube to the end of the bladder pressure monitoring tube, adding a plug and spring inside the anti-reflux tube. When bladder pressure increases and fluid refluxes, the plug closes to the end of the bladder pressure monitoring tube, preventing refluxed fluid from entering the pump body and other structures, thus avoiding cross-infection and ensuring accurate results. However, this method relies on a fixed-length connecting wire and Velcro to the bladder pressure monitoring tube, which cannot be adjusted according to usage and reduces the device's applicability. Therefore, a urodynamic testing device with an anti-reflux structure is proposed. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this invention provides a urodynamic testing device with an anti-reflux structure, thereby solving the aforementioned technical problems that not only cannot be adjusted according to usage conditions, but also reduce the applicability of the device.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a urodynamic testing device with an anti-reflux structure, comprising:
[0009] A bladder pressure measuring tube and an anti-reflux tube set at the end of the bladder pressure measuring tube, wherein the end of the anti-reflux tube is connected to an irrigation water pump, and a clamping tube is connected to the surface of the bladder pressure measuring tube, wherein an inlet and outlet groove is opened on the lower surface of the clamping tube, and elastic side blocks are evenly added to the inner cavity of the clamping tube.
[0010] Velcro is installed on both sides of the anti-backflow tube, and a connecting line is connected between the Velcro and the clamping tube. A connecting protrusion is installed at the end of the connecting line, and a protruding rod is installed on the surface of the connecting protrusion.
[0011] A connecting recess is provided on the surface of the Velcro and the clamp tube. Side connecting plates are added to both sides of the connecting recess, and side locking posts are inserted into the surface of the side connecting plates. Limiting sides and compression springs are added to the surface of each side locking post. After connecting the end of the bladder pressure monitoring tube to the patient, the irrigation pump delivers fluid to the patient's body along the anti-reflux tube and the bladder pressure monitoring tube, with the anti-reflux tube acting as an anti-reflux device. The clamp tube is first clamped onto the surface of the bladder pressure monitoring tube, with the elastic side block fitting against the surface of the bladder pressure monitoring tube. Then, the connecting protrusion at the end of the connecting wire is fitted into the connecting recess of the Velcro and the clamp tube. The protrusion is then inserted into the interior of the connecting recess. The compression spring, through the limiting side, drives the side locking posts to move along the side connecting plates, thus connecting the side locking posts and the protrusion. This design not only allows for replacement and adjustment of the connecting wire according to usage, improving the applicability of the equipment, but also facilitates the disassembly of the connecting wire from the Velcro and the clamp tube.
[0012] Preferably, side pull plates are installed on both sides of the inlet / outlet slot, and the side pull plates are connected to the clamping tube. The clamping tube can be pulled by the side pull plates to expand the size of the inlet / outlet slot, facilitating the separation of the bladder pressure monitoring tube from the clamping tube.
[0013] Preferably, the inner cavity of the anti-backflow tube is equipped with a plug and a spring, and the plug corresponds to the end position and shape of the anti-backflow tube. The anti-backflow tube can play an anti-backflow role through the plug and spring. Since the plug and spring are common anti-backflow structures, they will not be described in detail here.
[0014] Preferably, the side connecting plate is connected to the connecting recess, and the end of the side locking post extends inward through the outer wall of both the side connecting plate and the connecting recess. The side locking post can move along the side connecting plate and the connecting recess, and can be inserted into the interior of the connecting recess.
[0015] Preferably, the side locking post and the protruding rod are inserted into each other, and the protruding rod is also inserted into the connecting recess. The side locking post is inserted into the interior of the protruding rod within the connecting recess, thereby ensuring the stability of the connection between the protruding rod and the connecting recess.
[0016] Preferably, the elastic side blocks are evenly distributed on the inner wall of the clamping tube, and the elastic side blocks are in close contact with the surface of the bladder pressure monitoring tube. The elastic side blocks can ensure the stability of the connection between the clamping tube and the bladder pressure monitoring tube.

An irrigation pump then delivers fluid to the patient's body along the anti-reflux tube and the bladder pressure monitoring tube, with the anti-reflux tube acting as an anti-reflux mechanism. The tube clamp is first secured to the surface of the bladder pressure monitoring tube, with the elastic side block fitting against the surface. Then, the connecting protrusion at the end of the connecting cable is aligned with the Velcro and the connecting recess of the tube clamp. The protrusion is inserted into the connecting recess, and a compression spring, via a limiting side, moves the side locking pin along the side connecting plate, establishing a connection between the side locking pin and the protrusion. This design not only allows for easy replacement and adjustment of the connecting cable according to usage, but also improves the device's applicability and facilitates the disassembly of the connecting cable from the Velcro and the tube clamp.
