Chemotherapy is the first choice method for the medical treatment of malignant tumors, and the current clinical chemotherapy drugs can cause adverse reactions of different degrees, wherein nausea and vomiting are the most common adverse reactions caused by chemotherapy, and 70-80% of patients have nausea and vomiting of different degrees in the chemotherapy process. The vomit rate caused by the platinum-containing chemotherapy regimen is more than 90 percent. Among them, cisplatin is a chemotherapy drug causing high vomiting, resulting in poor control of nausea and vomiting, which not only affects the quality of life of patients, but also causes serious complications such as electrolyte disturbance, dehydration and malnutrition; the traditional Chinese medicine holds that the acupoint massage has the effects of warming and activating meridian, promoting spleen qi circulation, harmonizing stomach, regulating qi and reducing stomach qi, and can prevent nausea and vomiting. Neiguan point is one of eight confluent points, so it can regulate the balance of triple energizer, dredge qi movement of triple energizer, and regulate the function of intestines and stomach, and is mainly used for treating nausea, vomiting, stomachache, etc. By stimulating the channels and collaterals of the wrist and transmitting the signals upwards to the vomiting center, the signals for regulating nervous vomiting and the signals for reciprocating from the vagus nerve of the stomach are achieved, and the symptoms of vomiting, nausea and anorexia are relieved. Meanwhile, the Neiguan acupoint is stimulated to ensure that the upper, middle and lower triple energizer gases are unobstructed and the stomach-qi is descended through the Neiguan acupoint, thereby achieving the effect of treating nausea and vomiting. Benign stimulation can stimulate the integration and adjustment functions of a high-grade nerve center to generate a series of nerve and body fluid regulation, mobilize the potential disease resistance of the nerve and body fluid regulation, and achieve recovery cooperatively, acupuncture point massage is matched with an electronic antiemetic to achieve good intervention effect on prevention and treatment of chemotherapy-induced vomiting, which indicates that the traditional Chinese medicine acupuncture points of traditional Chinese medicine and the research and development of modern high-tech instruments in China are combined, and the conventional chemotherapy nursing mode is added, so that the traditional electronic antiemetic has obvious improvement effect on chemotherapy-induced nausea and vomiting, reduces chemotherapy-induced nausea and vomiting to the maximum extent, improves the quality of life, but the existing electronic antiemetic cannot control the treatment duration in the using process, so that medical care personnel need to supervise the treatment duration manually, and when a plurality of patients are treated at different times, medical personnel often forget to remember the duration to cause delayed treatment to the patients, the discomfort of the patient is increased, and the workload of the medical staff is also greatly increased, so that a novel electronic antiemetic instrument needs to be designed by the technical staff in the field.
