Problems solved by technology
[0004] The purpose of the present invention is to provide an automatic pressure-regulating negative pressure suction device with an automatic humidification function, which solves the problem that the negative pressure suction devices currently used in clinical practice cannot automatically adjust the pressure value for different operations, and manual adjustment is still required. Inconvenient, in addition, it is difficult to humidify the sputum that is too thick and inconvenient to suck during use, and there is a problem of poor suction effect

The invention discloses an automatic pressure regulating negative pressure suction device with an automatic humidifying function. The automatic pressure regulating negative pressure suction device comprises a tracheal catheter, and the tail end of the tracheal catheter is connected with a closed sputum suction tube; a humidifying tube port in the closed sputum suction tube is connected with a humidifying tube; the upper end of the humidifying tube is connected with an infusion apparatus; the infusion apparatus is connected with sterile humidifying liquid; a quantitative injector is additionally arranged outside a Murphy's dropper of the infusion apparatus; the quantitative injector is a pressure pump provided with a capacity sensor, and the Murphy's dropper is wrapped by a closed air bag of the quantitative injector; the tail end of the closed sputum suction tube is connected with the disposable negative pressure suction liquid storage bottle through a suction apparatus leather strap; and the other connector of the negative pressure suction liquid storage bottle is connected with a negative pressure suction pressure adjusting meter. Pressure modules are selected according to different sucked liquids (sputum, bile, intestinal juice, cerebrospinal fluid and the like), the standard negative pressure value range is adjusted through one key, use is convenient and fast, thick sputum can be automatically humidified according to sputum suction operation, the sputum becomes thin, and suction is convenient.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic pressure-regulating negative pressure suction device with an automatic humidification function. Background technique [0002] The negative pressure suction device is a tool that creates the negative pressure state of its suction head through a certain method, and the material outside the suction head is squeezed toward the suction head to complete the "suction" effect. Negative pressure suction is often used in tracheal suction, which is the primary and key measure in the management of the respiratory tract of mechanically ventilated patients. effect. Negative pressure is the driving force of sputum suction operation. Different negative pressures have different effects on the hemodynamics of mechanically ventilated patients. In addition, the duration of sputum suction, sputum volume and sputum viscosity will all affect the pressure. Setting a safe and effec...
