Low-frequency pulse vomiting stopping instrument having time control, and duration control method thereof

Abstract

The invention discloses a low-frequency pulse vomiting stopping instrument having time control. The low-frequency pulse vomiting stopping instrument comprises MCU control, a pulse generating system, physical key control, a liquid crystal scanning and displaying system, an electricity supply system, a USB charging interface, and a duration control card system, wherein the MCU control is used for producing a PWM signal to perform calculating and controlling on commands of each component and module of the electronic vomiting stopping instrument; the pulse generating system is used for producing alow-frequency pulse signal to stimulate the high-grade center of cerebral cortex to stop vomiting; the physical key control is used for controlling the switching on and the switching off of the electronic vomiting stopping instrument and adjusting the intensity of the pulse signal; the liquid crystal scanning and displaying system is used for displaying the operating state of the electronic vomiting stopping instrument; the electricity supply system is used for supplying electricity to each module of the electronic vomiting stopping instrument; the USB charging interface is used for chargingthe electronic vomiting stopping instrument through the USB interface; the USB charging interface is connected with the electricity supply system; and the duration control card system is used for MCUcontrol and is used for controlling the low-frequency pulse output duration of the pulse generating system through reading data in the duration control card system. Through the adoption of the low-frequency pulse vomiting stopping instrument disclosed by the invention, the treating duration is effectively controlled, so that during treatment, artificial supervision is not needed when a plurality of patients are treated in different durations, and the workload of medical personnel is greatly reduced.

Description

technical field [0001] The invention relates to the field of antiemetic technology, in particular to a time-controlled low-frequency pulse antiemetic instrument and a time-length control method thereof. Background technique [0002] Chemotherapy is the first choice for medical treatment of malignant tumors. Current clinical chemotherapy drugs can cause adverse reactions of varying degrees, among which nausea and vomiting are the most common adverse reactions caused by chemotherapy. Various degrees of nausea and vomiting occurred. The vomiting rate of platinum-based chemotherapy regimens is above 90%. Among them, cisplatin is a highly emetogenic chemotherapeutic drug, and the resulting nausea and vomiting are not well controlled, which not only affects the quality of life of patients, but also can lead to serious complications, such as electrolyte disturbance, dehydration, and malnutrition; traditional Chinese medicine believes that , acupoint massage has the effects of war...

AI Technical Summary

Problems solved by technology

Benign stimulation can stimulate the integration and adjustment functions of the advanced nerve center, produce a series of nerve and body fluid adjustments, mobilize the potential resistance to disease, and achieve recovery in coordination. The intervention effect shows that the combined application of traditional Chinese medicine acupoints in my country and modern high-tech instrument research and development, coupled with the routine nursing care of chemotherapy, can significantly improve the nausea and vomiting caused by chemotherapy, and reduce the nausea caused by chemotherapy to the greatest extent. Vomiting improves the quality of life, but the existing electronic antiemetic device cannot control the duration of treatment during use, resulting in the need for medical staff to manually monitor the duration of treatment. When multiple patients are treated at different times, Medical staff often forget the duration and cause delayed treatment to patients, resulting in increased discomfort for patients and greatly increasing the workload of medical staff. Therefore, there is an urgent need for those skilled in the art to design a new type of electronic antiemetic instrument
