Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to an intelligent temperature-controlled gastrointestinal lavage device. Background Art

[0002] Gastrointestinal lavage is a medical procedure used to cleanse the gastrointestinal tract, usually to treat or prevent certain diseases or in preparation for certain medical examinations. The main uses are:

[0003] Treatment of digestive system diseases: Gastrointestinal lavage can help remove harmful substances in the gastrointestinal tract, such as toxins, bacteria or food residues. It is especially beneficial for patients with digestive system diseases such as enteritis, colitis, and constipation.

[0004] Preparing for endoscopy: Before a gastrointestinal endoscopy, a gastrointestinal lavage is usually required to clear the contents of the intestine and ensure that the doctor can clearly observe the internal conditions of the intestine.

[0005] Preparation before intestinal surgery: Before intestinal surgery, gastrointestinal lavage can clean the intestines and reduce the risk of infection during surgery.

[0006] Detoxification and Cleansing: Some people choose to perform a gastrointestinal lavage as a way to detoxify and cleanse their bodies, especially when they are experiencing indigestion or need to remove accumulated toxins from their bodies.

[0007] Auxiliary treatment of certain diseases: Gastrointestinal lavage can also be used as an auxiliary treatment method for certain diseases, such as kidney disease, liver disease, etc.

[0008] Gastrointestinal lavage is usually performed in a medical institution by a professional medical staff. The solution used during the lavage may be water, saline, or other specific drug solutions, depending on the purpose of the lavage and the patient's condition.

[0043] Furthermore, a waste liquid barrel 35 is movably embedded in the table top of the support table 31, and the waste liquid barrel 35 is located at the bottom of the liquid storage component 2. Before the irrigation operation, the irrigation liquid first flows through the liquid channel to exhaust the air and perform a simple rinse.

[0044] Specifically, the preparation stage:

[0045] Place the related items required for the irrigation work on the multi-layer storage rack 34, inject the irrigation liquid into the liquid storage bag 21 after preparation, and ensure that it is well sealed; open the baffle 13 of the mounting box 11, and check that there is no problem with the status of the heating unit 15 and the temperature sensor 18. Insert the puncture head at one end of the infusion tube 22 into the bottom end of the liquid storage bag 21, and then hang the liquid storage bag 21 on the mobile hook 14, adjust the upper and lower positions of the mobile hook 14, and ensure that the bottom end socket of the liquid storage bag 21 can pass through the through hole 12 below. Then connect the other end of the infusion tube 22 to the top of the temporary storage tank 23. The flow sensor 26 below the temporary storage tank 23 is connected to the gastrointestinal irrigation equipment through a connector.

[0046] Close the baffle 13 and lock it, push the handle to advance the push plate 16 forward until the squeezing plate 17 at the front end is squeezed against the surface of the liquid storage bag 21. The elastic telescopic structure at the front end of the push plate 16 can play a buffering and telescopic role to ensure that the squeezing plate 17 can contact the liquid storage bag 21. The pin of the spring locking head 111 is inserted into the slot 110 to fix the push plate 16. The internal situation can be observed through the transparent window of the raised part of the baffle 13 during this process.

[0047] After the power supply 5 is turned on, the temperature, flow rate and other parameters are set through the touch screen of the control host 4, the heating unit 15 is started to heat the irrigating fluid, and the temperature sensor 18 monitors the temperature of the irrigating fluid in real time and transmits the data to the control host 4. According to the instructions of the control host 4, the heating unit 15 adjusts the power of the heater 151 to maintain the set temperature of the irrigating fluid. The control host 4 has a built-in intelligent temperature control algorithm, which automatically adjusts the working state of the heating unit 15 according to the real-time temperature data and the preset temperature target. The built-in intelligent temperature control algorithm of the control host 4 adopts a PID (proportional-integral-differential) control strategy, and calculates the adjustment amount of the heating unit according to the temperature deviation, the accumulation of the deviation and the rate of change of the deviation.

[0048] Irrigation process:

[0049] After heating to a suitable temperature, the flow regulator on the infusion tube 22 is turned on to allow part of the irrigation fluid to flow into the temporary storage tank 23. The temporary storage tank 23 serves as a temporary storage space for the irrigation fluid, so that the irrigation fluid can be continuously supplied during the irrigation process to avoid interruptions or instability caused by the direct delivery of the irrigation fluid. Since the irrigation fluid stays in the temporary storage tank 23 for a period of time, it can provide an opportunity for the temperature control component to adjust the temperature to ensure that the temperature of the irrigation fluid flowing through the patient is appropriate and stable. At the same time, it can help balance the pressure in the irrigation system and reduce the irritation or discomfort that may be caused to the patient due to pressure fluctuations. After that, the irrigation fluid flows through the temporary storage tank 23 and the irrigation tube, exhausts the excess air inside, and observes the liquid flow rate. The discharged liquid is discharged into the waste liquid barrel 35.

[0050] The flow sensor 26 continuously monitors the flow of the lavage fluid and transmits the data to the control host 4. The control host 4 calculates the required valve core position through the intelligent flow control algorithm based on the data of the flow sensor 26 and the preset flow, and instructs the precision flow control valve 24 to adjust the flow accordingly. At the same time, the high-precision pressure sensor 25 monitors the pressure of the lavage fluid in real time to ensure that the drainage is temporarily shut down after the pressure is stable. Under visual guidance, gastrointestinal lavage is delivered into the patient's intestines using an instrument pipeline. Medical staff input the required lavage fluid flow through the touch screen display 16 of the control host 4.

[0051] The irrigation is started by controlling the host 4, and the medical staff adjusts the flow rate and temperature of the irrigation liquid according to the patient's reaction and the irrigation effect. After the irrigation is completed, the precision flow control valve 24 and the heating unit 15 are closed. After the operation, the remaining irrigation liquid in the liquid storage bag 21 and the temporary storage tank 23 is emptied, the disposable utensils are taken away, the top opening of the temporary storage tank 23 is opened, the inside is rinsed and cleaned with disinfectant liquid, and the waste liquid barrel 35 is taken out to treat the waste liquid.

[0052] The present invention realizes precise control of the temperature of the irrigation fluid and ensures the stability of the flow of the irrigation fluid through the temperature control component and the liquid storage component, solves the problems of inaccurate and uneven manual temperature adjustment and inaccurate and susceptibility to interference of flow control in the prior art, improves the accuracy and safety of treatment, and reduces the discomfort of patients; and automatically monitors and adjusts the temperature and flow, reduces the operating steps of medical staff, solves the problems of complex and time-consuming operations in the prior art, and improves work efficiency; and through real-time monitoring of temperature sensors and flow sensors, and the data recording function of the control host, precise monitoring of the irrigation process is achieved, solves the problem of lack of real-time monitoring and data recording in the prior art, and helps to optimize the treatment plan.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
