Double-sleeve pipe negative-pressure flushing integrated machine

Abstract

The present invention discloses a double-sleeve pipe negative-pressure flushing integrated machine and belongs to the field of negative-pressure flushing. The double-sleeve pipe negative-pressure flushing integrated machine comprises a flushing fluid module, a PLC controller and a negative-pressure bottle; negative-pressure ends of the flushing fluid module and the negative-pressure bottle are connected to a drainage position in an abdominal cavity of a patient through pipes, the flushing fluid module and the negative-pressure bottle are both connected with the PLC controller, and opening andclosing of the flushing fluid module and the negative-pressure bottle are controlled by the PLC controller; a first gravity sensor is arranged at a lower end of the flushing fluid module; and a secondgravity sensor is arranged on a pipe between the negative-pressure bottle and the patient, the first gravity sensor and the second gravity sensor are used for monitoring amount of liquid in the flushing fluid module and the negative-pressure bottle all the time, comparison is conducted through the PLC controller, when a difference value is too large and exceeds a preset value, an alarm is given in time, abnormal information is transmitted to medical staff, therefore, abnormal conditions can be found in time and solved, and a situation that the abnormal conditions are not found in time is effectively avoided.

Description

technical field [0001] The invention relates to the field of negative pressure flushing, and more specifically relates to a double-tube negative pressure flushing integrated machine. Background technique [0002] Postoperative anastomotic flaccidity is a common serious postoperative complication in patients with gastric cancer and colorectal cancer. Once it occurs, the treatment time will be prolonged, the treatment difficulty will increase, and the complication will be more serious. The mortality rate was as high as 50% before the 1970s ~60%, up to now it is still 15% ~ 20% [2], the most effective treatment method is the continuous flushing of the double cannula in the abdominal cavity. Inject antibacterial drugs to inhibit infection. The most important point in the nursing measures of double cannula is to keep the drainage unobstructed, strictly record the 24-hour intake and output, and judge the change of the condition by the color and output of the drainage. The traditio...

[0003] When recording the intake and output of the traditional drainage device, it is generally recorded one bag at a time. When recording the intake at 7 o'clock in the morning, the remaining amount of the 2000ml large bag of normal saline is estimated, and the recorded output is dumped and recorded once. There is also an estimation of the 3000ml large bucket. , the nurses’ subjective factors in the record of intake and output are relatively large, and the error is large, which has a certain impact on the judgment of the disease. Due to the busy work, the statistics are made once a day, and the intake is obviously more than the output, and the flushing fluid accumulates in the abdominal cavity without any It was detected in time, and there was negative pressure. Gastrointestinal surgery was radically cured, and blood vessels were exposed after lymphadenectomy. The blood vessels were corroded by fistula fluid, and bleeding was caused after long-term flushing. If it was not discovered in time during flushing, it would lead to changes in the condition and unnecessary dispute
