Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical instruments, and specifically relates to a medical endoscope water feeding system with adjustable temperature. BACKGROUND

[0002] The endoscope water feeding device is an important auxiliary equipment used in cooperation with an endoscope. Its main function is to accurately deliver an appropriate amount of water to the water channel of the endoscope for use in endoscopic examination or treatment operation, such as gastroscopy, enteroscopy, hysteroscopy examination and gastrointestinal endoscopy diagnosis and treatment, for flushing tissues, removing blood, excrement and other organic matter, so as to improve the visibility of diagnosis and treatment in the endoscopic diagnosis and treatment process.

[0003] The endoscope water feeding device inputs water with different temperatures into the cavity, which can play different roles in diagnosis and treatment, such as water close to human body temperature can relieve the spasm of the cavity organs, and cold water with a temperature of 5-12 DEG C can play a role in hemostasis. Therefore, the endoscope water feeding system with adjustable temperature can improve patient comfort, improve diagnosis and treatment efficiency and effect.

[0004] However, the current endoscope water feeding device has the following defects:

[0005] 1. Temperature cannot be adjusted: although there is a water temperature monitoring device, the temperature cannot be adjusted, but in actual use, the set accurate temperature cannot be maintained all the time, and the uncontrolled water temperature can cause discomfort to the patient, especially during long operation process, which has no promoting effect on the diagnosis and treatment effect and efficiency.

[0006] 2. Poor water flow stability: the flow rate and pressure of the water feeding are not stable enough, and the water flow may be large or small, which is not conducive to clearly and stably flushing the endoscope field of view, and affects the observation and treatment effect, for example, it may interfere with the doctor's operation during fine endoscopic operation, and reduce the efficiency.

[0007] 3. Easy to block: the pipeline and related parts of the water feeding device may be blocked due to the accumulation of impurities, tissue debris and the like in the water, and once blocked, the operation needs to be suspended for cleaning and repair, which delays the diagnosis and treatment time and increases the pain of the patient.
