Problems solved by technology

[0004] (1) The existing constant temperature flushing water injection pump device is designed in separate parts, which is inconvenient to carry, and it is not convenient to quickly build a diagnosis and treatment platform
[0005] (2) During the use of the existing constant temperature flushing water injection pump device, the water temperature uniformity is poor, and the deviation of the water temperature during the diagnosis and treatment process exceeds the comfort level of the internal cavity and intestinal tract of the human body, which may easily cause discomfort to the patient
[0006] (3) The existing water injection pump interface is limited to use in therapeutic endoscopes, and ordinary inspection endoscopes cannot be connected, and the availability rate is low

Embodiment 1

[0083] Technical indicators of the present invention are as follows:

[0084] 1. Working temperature: 5℃~40℃;

[0085] 2. Relative humidity of the environment: ≤85% (no condensation);

[0086] 3. System power supply: AC220V±10% / 50Hz;

[0087] 4. Pressure setting range: 50~500mmHg;

[0088] 5. Flow setting range: 0.1L / min (100mL / min) ~ 1.0L / min (1000mL / min);

[0089] 6. Operation mode: continuous operation, driven by stepping motor, stable operation and low noise;

[0090] 7. Constant temperature method: preheating type;

[0091] 8. Noise: <70dB(A);

[0092] 9. Equipment safety classification: Class I BF type non-AP / APG equipment.

Embodiment 2

[0094] When the user uses this device, the height and position of the main body of the irrigation pump are not the same, which will cause the difference between the displayed pressure value in the cavity and the actual pressure value in the cavity. The details are as follows:

[0095] 1. The pressure displayed in the cavity of the perfusion pump is the actual pressure in the cavity when the output liquid level of the sensor infusion set is at the same level as the perfusion cavity.

[0096] 2. When the liquid surface rises or falls relative to the level of the chamber, the actual pressure in the chamber also rises or falls, and the rise and fall values ​​should be equal to the displayed value of the pressure in the chamber plus or minus the difference between the liquid level and the chamber. The pressure generated by the height difference between them (1 meter height difference = 10KPa).

Abstract

The invention belongs to the technical field of medical instruments, and discloses a constant-temperature flushing water injection pump system used in the endoscope diagnosis and treatment process, a control method and a terminal. A water injection pump is arranged in a control box; and a constant-temperature water bath is arranged on the upper portion of the control box; a multi-point acquisition temperature controller is arranged on the left side of the constant-temperature water bath and is connected with the control circuit board through a data line; the constant-temperature water bath is sleeved with a pure water tank, and a water injection pump water inlet silicone tube is placed in the pure water tank; a magnetic stirring heating plate is arranged at the bottom of the water bath, and a polytetrafluoroethylene stirrer is arranged in the pure water tank for stirring. The constant-temperature tank is connected with the water pump through the biopsy hole channel or the auxiliary water supply hole channel, all soft endoscopes can be compatible, and the flushing effect is good; the water circulation does not pass through the interior of the instrument, and the high-quality plastic water pipe can be disinfected and sterilized by being soaked in various disinfectants and disinfected and sterilized by ethylene oxide, so that the sensing control requirement is met.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a constant temperature flushing water injection pump system, a control method and a terminal for flexible endoscope diagnosis and treatment. Background technique [0002] The flushing water injection pump or perfusion pump mainly uses the peristaltic pump to pressurize the pure water to pressurize and expand the cavity of the flushing object, which is suitable for forming a visible space and flushing in the cavity during endoscopy and surgery. At present, the conventional constant temperature water injection pump technology route in the market adopts the method of placing a constant temperature control device next to the original water injection pump, and placing the pure water tank inside. This method adopts a split design, and the temperature of the pure water in the pure water tank is uneven. It makes the constant temperature water injection pump inconvenie...
