Description

Technical Field

[0001] This utility model belongs to the field of anorectal manometry technology, specifically relating to an intelligent inflation / deflation device for anorectal manometry. Background Technology

[0002] Anorectal diseases are a common type of digestive system disease that poses a serious threat to human health. Anorectal manometry has a wider clinical application, primarily assisting in the diagnosis of anorectal diseases such as congenital megacolon, fecal incontinence, and functional constipation. For functional constipation, anorectal manometry can assess anorectal motility and sensory abnormalities, aiding in subtyping diagnosis and guiding clinical treatment. It can also evaluate surgical outcomes and medications, and guide treatment plans such as biofeedback therapy. Traditional diagnostic methods, such as visual inspection, palpation, and digital rectal examination, while simple and easy to perform, have limitations such as strong subjectivity and insufficient diagnostic accuracy.

[0003] With the continuous advancement of medical technology, especially the rapid development of medical imaging and sensor technologies, anorectal manometry devices have evolved from early multi-channel physiological recorders to high-resolution, multi-channel anorectal motility detectors. The pressure sensor system uses probes to sense the pressure within the rectum and anal canal, transmitting the signal via catheter to a computer and recording device to display or print out the rectal and anal canal pressure graph. During this type of manometry, stimulation needs to be applied to the anorectal area to elicit a corresponding response, which serves as a basis for assessing the anorectal condition. Currently, the mainstream stimulation input method involves inserting a balloon into the rectum and manually inflating and deflating it with a syringe to simulate feces and stimulation. There are two main modes:

[0004] 1. Simulate RAIR (inhibitory reflex of internal anal sphincter caused by rectal dilation) rapid inflation: Requires rapid inflation of up to 60ml within 1 second, and rapid deflation after inflation;

[0005] 2. Simulated sensory test: Slowly inflate the air according to the patient's needs until the patient experiences the following sensations, and record the corresponding inflation volume:

[0006] (1) Feeling

[0007] (2) Feeling the urge to defecate

[0008] (3) Sense of embarrassment

[0009] (4) Maximum tolerance;

[0010] However, the existing manual inflation method has the following drawbacks:

[0011] 1. Connecting the equipment, repeatedly pushing and pulling the syringe, and recording the inflation and deflation volumes are relatively cumbersome operations;

[0012] 2. The inflation speed is uneven, uncontrollable, and lacks quantitative control;

[0013] 3. The inflation volume is inaccurate, difficult to record and label, and inconsistent with repeated operations;

[0014] 4. The venting speed is slow, and manual evacuation is laborious and ineffective.

[0015] Therefore, further improvements will be made to address the aforementioned issues. Utility Model Content

Through the linkage of a shell module, a drive module, and an inflation / deflation module, it can automatically and precisely control the inflation and deflation of the air bladder, thereby simulating the physiological process of stimulating rectal expansion and relaxation.

[0025] I. Improve the accuracy and reliability of anorectal manometry

[0027] II. Simplify operating procedures and reduce patient discomfort

[0028] Traditional anorectal manometry requires manual control of the inflation and deflation of the balloon, which is cumbersome and prone to human error. The automatic inflation / deflation device automates this process, simplifying the procedure and improving efficiency. Furthermore, because the device can precisely control pressure changes within the balloon, it reduces patient discomfort and enhances examination comfort.

[0040] Preferred embodiment.

[0041] like Figure 1-3 As shown, this utility model discloses an intelligent inflation / deflation device for anorectal manometry, comprising a housing module 100 and a drive module 200 and an inflation / deflation module 300 mounted on the housing module 100, wherein:

[0042] The drive module 200 includes a mounting bracket 210, a drive motor 220, a lead screw 230, a first guide rod 240, a second guide rod 250, a slider 260, and a connecting block 270. The mounting bracket 210 includes a first vertical plate 211, a second vertical plate 212, and a top plate 213. The top plate 213 is fixedly installed between the first vertical plate 211 and the second vertical plate 212. The drive motor 220 is fixedly installed on the side of the first vertical plate 211 away from the second vertical plate 212. One end of the lead screw 230 passes through... The first vertical plate 211 is connected to the drive end of the drive motor 220, and the other end of the lead screw 230 is installed on the second vertical plate 212; the first guide rod 240 and the second guide rod 250 are both installed between the first vertical plate 211 and the second vertical plate 212; the middle part of the slider 260 is threadedly connected to the lead screw 230, and the two ends of the slider 260 are respectively sleeved on the first guide rod 240 and the second guide rod 250; the connecting block 270 is fixedly installed on the slider 260.

[0043] The inflation / deflation module 300 includes a cylinder 310, a first air pipe 320, a second air pipe 330, an air path connecting plate 340, a solenoid valve assembly 350, a pressure sensor 360, and a third air pipe 370. The cylinder 310 is fixedly connected to the connecting block 270. The first air pipe 320 and the second air pipe 330 are respectively connected between the cylinder 310 and the air path connecting plate 340. The solenoid valve assembly 350 and the pressure sensor 360 are respectively mounted on the air path connecting plate 340. One end of the third air pipe 370 is connected to the air path connecting plate 340, and the other end of the third air pipe 370 is connected to a balloon (not shown).

[0044] Specifically, the mounting bracket 210 is also provided with a third vertical plate 214 fixedly connected to the top plate 213. The third vertical plate 214 is located between the first vertical plate 211 and the second vertical plate 212. The third vertical plate 214 is provided with a first limit switch 215, and the second vertical plate 212 is provided with a second limit switch 216 (for detecting the movement state of the slider and the connecting block).

[0045] More specifically, the cylinder 310 is fixedly connected to the housing module 100 (top plate not shown) via a fixing plate 311 (to improve the structural stability of the cylinder).

[0046] Furthermore, it also includes a communication module 400, which is electrically connected to the drive motor 220, the solenoid valve assembly 350 and the pressure sensor 360 respectively (for controlling the working state).

[0047] Furthermore, the communication module 400 is connected to a host computer (for remote control and real-time display of relevant pressure data on the host computer).

[0048] Preferably, the gas connection plate 340 is further provided with a mechanical pressure relief safety valve.

[0049] Regarding this utility model:

[0050] 1. Gas source selection: The use of a metal bidirectional cylinder of appropriate volume solves the shortcomings of traditional syringes, such as short service life, poor structural strength, relatively complex fixing method, and poor output continuity caused by unidirectional inflation and deflation. The cylinder volume is greater than 70ml, and a single stroke can meet the requirement of a maximum of 60ml for a single RAIR. The switchable cylinder output chamber reduces inflation and deflation jolts and improves test accuracy and smoothness.

[0051] 2. Air circuit settings: Set up a solenoid valve assembly, and realize functions such as air circuit closure, natural pressure relief, cylinder air extraction and pressure relief, and switching between the inlet and outlet of the bidirectional cylinder through program settings or manual control of the host computer.

[0052] 3. High-precision transmission control: A high-speed stepper motor is used in conjunction with a high-precision transmission screw or synchronous belt structure to drive the cylinder piston to move, achieving precise control, rapid response and high-speed movement.

[0053] 4. Air pressure monitoring: By installing a high-precision pressure sensor in the airway, the pressure changes in the airway can be detected in real time to obtain the actual volume of the rectal balloon, and the feedback can be sent to the host computer for precise control.

[0054] 5. Safety protection: Equipped with a high-precision mechanical pressure relief safety valve, which automatically releases pressure to prevent safety accidents when the internal pressure of the gas circuit exceeds the set safety limit.

[0055] The principle of this utility model is as follows:

[0056] For balloon inflation, the device starts operating and performs preparatory actions. The solenoid valve assembly opens and closes the corresponding air passages. The stepper motor drives the lead screw to rotate, causing the slider to move the cylinder piston towards the second limit switch until it is triggered. It then moves a short distance in the opposite direction and slowly approaches the second limit switch again until it is triggered and stops. This position is set as the zero point. Then, keeping the solenoid valve assembly connected to the outside, the cylinder piston moves towards the first limit switch. At this time, controlled by the solenoid valve assembly, the first and third air tubes are connected in the air passage connection plate, thereby realizing the inflation of the balloon. If further inflation is needed... Continuous inflation occurs after the first stroke switch is reached, as the piston moves towards the second stroke switch. At this point, controlled by the solenoid valve assembly, the second and third air tubes are connected in the air circuit connection plate, allowing for continued inflation of the balloon. This ensures that during the cylinder's reciprocating motion, one of the first / second air circuits inflates the third air circuit and the balloon, while the other connects to external air pressure, until the balloon reaches the preset inflation value. Deflating the balloon is achieved by reversing the settings. Combined with the continuous output of the bidirectional cylinder, this reduces inflation / deflation jerks, minimizing patient discomfort and improving testing comfort. Depending on the actual anorectal pressure measurement, different modes can be selected to automatically inflate and deflate the balloon.

[0057] It is worth mentioning that the technical features of the anorectal region and host computer involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0058] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
