Description

Self-adaptive anti-emetic device and regulation and control method Technical Field The invention relates to the technical field of antiemetics, and particularly provides a self-adaptive antiemetic device and a regulating and controlling method. Background Nausea and emesis caused by pregnancy, motion sickness, sea sickness, VR vertigo, surgical operation, cardiovascular and cerebrovascular diseases, chemotherapeutics, etc. are common clinical symptoms. These vomiting mechanisms are quite complex, but the entire process is thought by the learner to be controlled primarily by central vomiting regulation. The vomiting center located in the brainstem is responsible for regulating the vomiting response and this area receives stimulus information from a number of neural pathways including the throat, gastrointestinal tract, mediastinum and the stimulation of the advanced cortical center, visceral signals, visual and vestibular signals, on the other hand, the stimulation of the sensory stimulation area. Both of these pathways stimulate central emetic reflex, resulting in nausea and vomiting. The Chinese medicine acupuncture theory considers that the 'Neiguan' acupoint is a special effect acupoint for relieving nausea and vomiting. The Neiguan acupoint is a point on the pericardium meridian, located on the medial side of the forearm, about 2 cun on the lateral axis of the wrist. The theory of traditional Chinese medicine holds that the interior-closed point has the following mechanism and effect in relieving nausea and vomiting, namely the stimulation of the interior-closed point can help harmonize spleen and stomach and strengthen digestion function, so that nausea and vomiting caused by spleen and stomach imbalance are reduced. Acupuncture or massage on the interior-closed points can dredge the pericardium channels and collaterals, improve qi and blood circulation and relieve discomfort. Stimulation of Neiguan acupoints helps to pacify heart spirit, reduce anxiety and tension, and thereby reduce the influence of emotion on nausea and vomiting. Stimulation of Neiguan acupoints can promote local and systemic blood circulation and enhance the adaptability of the body to discomfort. The stimulation of the Neiguan acupoint can effectively relieve nausea and vomiting caused by various factors, such as vomiting of pregnancy, nausea caused by chemotherapy, and the like. Clinically, many patients can obviously feel the reduction of nausea and the reduction of vomiting frequency after receiving acupuncture or acupoint massage. In a word, the mechanism of vomiting is complicated, and traditional Chinese medicine can relieve the symptoms of nausea and vomiting to a certain extent by adjusting the interior-closure point, so that the traditional Chinese medicine has good clinical application prospect. Although related electronic antiemetic devices appear on the market, through simulating bioelectric signals, the stimulation to acupuncture points of a user is periodically carried out to relieve vomiting symptoms, but the electronic antiemetic device is complex in use and operation, inconvenient to wear by a single person and few in optional gears. And the stimulus intensity cannot be adjusted according to the individual situation of the user, and may be counterproductive. And after the wearer uses the gel for a long time, the wearer is numb in constant stimulation intensity, and the expected effect cannot be achieved. Disclosure of Invention Based on the above, the invention provides a self-adaptive anti-emetic device and a control method, so that the stimulation intensity can be adjusted according to the personal condition of a user, and the stimulation intensity can be adjusted in real time, thereby effectively relieving the symptoms of vomiting and providing a use effect. The invention provides a self-adaptive antiemetic device which comprises a shell, a pulse wave detection unit, a discharge circuit, electrode plates and a control unit, wherein wristband assemblies are arranged at two ends of the shell, the electrode plates are arranged at the bottom of the shell and are connected with the discharge circuit, the electrode plates are tightly attached to acupuncture points of a wrist of a user through the wristband assemblies, the pulse wave detection unit detects pulse signals of the user, and the control unit receives and controls the discharge circuit to release adjustable pulse current according to the detected pulse signals and acts on the acupuncture points of the user through the electrode plates. Further, the invention provides a self-adaptive antiemetic regulation method, and the pulse wave measurement method comprises the following steps of: S110, fixing the shell on the wrist of a user by using a wrist strap, and enabling two electrodes to be positioned at two sides of the inner joint point; s120, obtaining body effective data of a user through a pulse wave detection unit, selecting proper stimulus intensity throug
