Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a warm-cold dual-source constant-temperature water injection device for digestive endoscopy diagnosis and treatment. Background Art

[0002] In gastrointestinal endoscopy, the room temperature water currently injected by the endoscopic water injection system is too cold compared to the natural temperature of the human gastrointestinal tract. Low temperature stimulation can easily cause gastrointestinal spasm, affect the field of view of diagnosis and treatment, and is not conducive to the detection of early lesions under gastroscopy and colonoscopy, such as adenoma and early cancer. In addition, in the treatment of polyps and early cancer under gastroscopy and colonoscopy, it will prolong the treatment time, increase the difficulty of operation, and bring certain risks of complications. In ultrasound endoscopy, low temperature water increases gastrointestinal motility and spasm, which is not conducive to the diagnosis of the nature and level of the lesions, resulting in prolonged operation time and increased risk of complications. In addition, this low temperature stimulation can also easily cause abdominal discomfort and abdominal pain in patients after surgery.

[0003] Ordinary colonoscopy without sedation / analgesia is beneficial to both patients and endoscopists: patients will not be exposed to the potential side effects and risks of sedation / analgesia, and do not need to be accompanied home, which reduces missed work days and time, and reduces medical expenses. From the perspective of endoscopists, patients recover faster after non-sedated colonoscopy, which reduces post-examination monitoring and reduces surgery-related costs. Therefore, there is a great need for a non-sedated colonoscopy diagnosis and treatment method that can minimize patient discomfort. In recent years, some researchers have proposed using warm water injection instead of conventional air injection to expand the colon during colonoscope insertion to obtain a better endoscopic field of view, reduce colon spasms, and relieve patient pain.

[0004] During gastroscopy and colonoscopy, when removing polyps, peeling off lesions or performing emergency endoscopic hemostasis, injecting warm water at 37°C is not conducive to hemostasis. It is necessary to use cold water (such as 4°C) to stimulate the contraction of blood vessels on the surface of the gastrointestinal mucosa to achieve the purpose of hemostasis or improve the endoscopic field of view, which is conducive to the further implementation of other measures (for example, metal clip closure hemostasis). However, 20°C normal temperature water cannot meet this demand.

[0005] At present, most domestic hospital endoscopy centers routinely use endoscopy water injection systems during endoscopic diagnosis and treatment. The system basically consists of an electric water pump connected to a water storage container through a connecting pipe, and the water outlet temperature is room temperature (about 20°C, which varies with the air temperature). In gastrointestinal endoscopic diagnosis and treatment, the room temperature water currently injected is too cold and low compared to the natural temperature of the human gastrointestinal tract. The existing endoscopy water injection system cannot meet the demand for warm water injection (about 37°C). In order to improve the diagnosis and treatment effect, medical staff often need to specially prepare 37°C sterile water, which is often time-consuming and laborious. In addition, due to the lack of a constant temperature heat source, the prepared warm water will cool down over time, ultimately affecting the diagnosis and treatment effect.

[0006] During gastroscopy and colonoscopy, when removing polyps, peeling off lesions or performing emergency endoscopic hemostasis, nurses usually have to go to the refrigerator to get 4°C sterile water for injection, or temporarily put the sterile water for injection at room temperature in the refrigerator for rapid freezing, which is very inconvenient.

[0007] How to provide warm water at around 37°C and cold water at 4°C during endoscopic diagnosis and treatment is a technical problem that needs to be solved urgently.

[0008] Patent CN202122066495.6 discloses a constant temperature endoscope water injection pump, including a water injection pump and a temperature control component, the water injection pump includes a speed control component, a booster pump, a power switch and a foot pedal, the temperature control component is fixedly connected to the water injection pump, and the temperature control component is an L-shaped structure, including a display screen, a temperature control button and a platform, and a constant temperature water bath is fixedly provided on the upper surface of the platform. The electric heating wire in the constant temperature endoscope water injection pump is evenly arranged in the barrel wall of the constant temperature water bath, and the water in the constant temperature water bath can be evenly heated to avoid uneven heating of the water storage bag. However, it is impossible to stably provide warm water at about 37°C and cold water at 4°C during endoscopic diagnosis and treatment, and it is impossible to monitor the water level to achieve the technical effect of taking it at any time. Summary of the invention

[0009] The purpose of the present invention is to overcome the above-mentioned defects of the prior art and provide a warm and cold dual-source constant temperature water injection device for digestive endoscopy diagnosis and treatment, which can prepare and provide warm water of about 37°C and cold water of 4°C during the endoscopic diagnosis and treatment process, and greatly improve the space utilization of the digestive endoscopy diagnosis and treatment platform. The diagnosis and treatment process is more convenient and efficient, and the patient experience and diagnosis and treatment effect are improved.

[0010] The present invention provides a warm and cold dual-source constant temperature water injection device for digestive endoscopy diagnosis and treatment, comprising: a box shell, a warm water tank, a cold water tank, a control panel, a system power supply, a circulating water pump, and a main control chip;

[0011] The control panel is installed on the box shell, and the warm water tank, cold water tank, system power supply, and circulating water pump are all installed inside the box shell;

[0012] The warm water tank is a 37°C warm water tank, and the cold water tank is a 4°C cold water tank; both the warm water tank and the cold water tank are provided with temperature sensors, and the warm water tank is provided with a heating unit; both the warm water tank and the cold water tank are provided with pressure sensors for judging the water volume; the circulating water pump is powered by a system power supply;

[0013] The control panel is electrically connected to the main control chip, and the circulating water pump, the refrigeration unit, the heating unit, the pressure sensor, and the temperature sensor are electrically connected to the main control chip respectively.

[0014] The control panel combines knobs and buttons to achieve switching between warm water and cold water, water filling and water stop control, and stepless adjustment of water flow speed, aiming to provide an intuitive and convenient operating experience.

[0015] Furthermore, the heating and cooling devices are customized according to the shape and size of the water container to achieve uniform distribution of the heat field. The heating unit is arranged at the bottom of the warm water tank, and the cooling unit is arranged at the bottom of the cold water tank; the temperature sensors are arranged at the bottom of the warm water tank and the cold water tank to ensure the consistency of the outlet water temperature.

[0016] Furthermore, the circulating water pump is a peristaltic pump with a small size and flexible speed regulation to achieve precise flow rate control.

[0017] Furthermore, the pipelines connecting the circulating water pump and the warm water tank and the cold water tank adopt a Y-shaped split-join structure. The pipeline layout is optimized to ensure the effective separation of warm water and cold water, and a one-way valve and an electrically controlled water valve switch are set to effectively avoid the backflow problem of flushing water.

[0018] Furthermore, the heating unit is a silicone rubber heating sheet.

[0019] Furthermore, the cold water circulates from the refrigeration unit through the sixth hole into the circulating water pump and then sequentially through the sixth hole and the fourth hole into the cold water tank.

[0020] Furthermore, after the warm water circulation is heated by the heating unit at the bottom of the warm water tank, it enters the circulating water pump through the third hole, the fourth hole, and the sixth hole in sequence and then returns to the warm water tank for continuous heating.

[0021] Furthermore, the system power supply inlet is the first hole, and the cooling vent of the refrigeration device is the fifth hole.

[0022] Furthermore, the box shell is also provided with wire entry and exit holes: a second hole and a seventh hole.

[0023] Furthermore, the refrigeration unit is connected to a refrigerator power supply through an eighth hole.

[0024] Here’s how it works:

[0025] After installing the control circuit. In the preparation stage for digestive endoscopy diagnosis and treatment, turn on the power of the device, open the control panel, and inject a certain amount of sterile water into the warm water tank and the cold water tank so that the pressure sensor under the box reaches the specified threshold to allow the device to heat or cool. Set the required warm water and cold water temperatures through the control panel, and set the start and stop of the circulating water pump, the pump speed of the circulating water pump, and the rotation direction of the pump body to adjust the water flow rate. Check the control panel. When the temperature reaches the set value, the pressure foot start device is connected to the tenth hole, and cold water output or warm water output is selected in the control panel. The required warm water or cold water is pumped out by the circulating water pump through the ninth hole. When the temperature reaches the set value, the system starts to keep warm, and the circulating heating ensures that it can be used at any time during digestive endoscopy diagnosis and treatment. When the sterile water in the warm water tank and the cold water tank reaches the warning water level of the pressure sensor device, the device starts to warn. When the amount of sterile water does not reach the threshold of the pressure sensor under the tank, the heating unit and the refrigeration unit stop working.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] The present invention provides a constant temperature and flow rate adjustable water injection device, which can provide 37℃ and 4℃ sterile water with constant and controllable temperature as needed during endoscopic diagnosis and treatment. In addition, the device is also equipped with a water level alarm function. When the water level of any water source, warm water or cold water, is lower than or higher than the preset warning line, the sound and light alarm system can be automatically triggered. The use of the device is conducive to improving the efficiency of endoscopic diagnosis and treatment and making endoscopic diagnosis and treatment more humane.

[0028] The device is powered on. After a certain amount of sterile water is injected into the cold water tank, the pressure sensor under the cold water tank reaches the specified threshold, thereby starting the refrigeration device to cool down until 4°C, and then maintaining the insulation state when the pressure sensor reaches the specified threshold. After a certain amount of sterile water is injected into the warm water tank on the device, the pressure sensor under the warm water tank reaches the specified threshold, thereby starting the heating device to heat the rinse measuring cup to the specified temperature. Ensure that it is available at any time during digestive endoscopy diagnosis and treatment. When the sterile water in the warm water tank and the cold water tank reaches the warning water level of the pressure sensor device, the warning device starts. When the amount of sterile water does not reach the threshold of the pressure sensor under the tank, the heating device and the refrigeration device stop working. The diagnosis and treatment process is more convenient and efficient, and the patient experience and diagnosis and treatment effects are improved. BRIEF DESCRIPTION OF THE DRAWINGS
