Wherein when the liquid level is higher than first sensor 501 and be less than second sensor 502, can also report through 11 languages of alarm device and remind the patient to walk about, in order to alleviate palirrhea influence, when palirrhea liquid level is higher than second sensor 502 and be less than third sensor 503, 11 voice broadcast of accessible alarm device lets the patient accelerate walking step, and transmit alarm signal to the interactive platform of doctorsing and nurses, inform medical personnel, carry out relevant processing, supplementary patient gets rid of flatulence in the stomach or excretes, avoid because the patient judges to make mistakes and leads to the medical negligence to take place. When the level of regurgitated fluid is above the highest third sensor 503, indicating that regurgitation is too severe, the delivery of the liquid must be suspended and the purgative may continue to be delivered when the patient's stomach is no longer regurgitated. Meanwhile, medical staff are informed to properly treat the regurgitation of the stomach of the patient.

The enema device and the enema method provided by the embodiment of the invention have the following principle:

utilize nasogastric tube 3 to pass through the nasal cavity with the laxative and lead patient's stomach, the uncomfortable taste of laxative has been avoided the patient to taste, can satisfy the enema of the patient who is unwilling to take the laxative orally, the comfort of patient enema has been improved, wherein locate the nasogastric tube 3 through the communicating sleeve pipe 4 cover with the atmosphere outside, can be with the palirrhea to the sleeve pipe 4 of stomach liquid, compare and connect a breather pipe in addition, the mode of cover establishing can reduce the volume of stretching into the nasal cavity, alleviate the foreign body sensation when the patient uses, and the space in patient's stomach occupies also littleer, reduce the degree of difficulty of adjustment nasogastric tube 3. The height of the current reflux liquid level can be detected by the liquid level sensor 5, the conveying flow rate of the cathartic can be adjusted by the flow meter 2 electrically connected with the liquid level sensor 5, and the phenomenon that the stomach of the patient is too seriously refluxed due to too fast flow rate is avoided. Physical discomfort due to reflux is avoided.

An enema method according to claim 8, wherein the liquid level sensor (5) includes a first sensor (501), a second sensor (502) and a third sensor (503) which are arranged at intervals from bottom to top, the liquid level sensor (5) reads data to determine whether there is liquid flowing back into the casing (4), if so, the flow meter (2) is adjusted to slow down the flow rate of the purgative, comprising the steps of:

judging the backflow height of the liquid according to the data of the first sensor (501), the second sensor (502) and the third sensor (503);

-if the level of reflux liquid is below the first sensor (501), adjusting the flow meter (2) to deliver purgative at a first flow rate;

-if the level of reflux liquid is above the first sensor (501) and below the second sensor (502), adjusting the flow meter (2) to deliver purgative at a second flow rate, the second flow rate being lower than the first flow rate;

-if the level of the reflux liquid is above the second sensor (502) and below the third sensor (503), adjusting the flow meter (2) to deliver purgative at a third flow rate, the third flow rate being lower than the second flow rate;

-adjusting the flow meter (2) to stop the delivery of the laxative if the level of the reflux liquid is higher than the third sensor (503).
