Infusion medicament analgesic patch

Abstract

The invention relates to an external medicament, in particular to an infusion medicament analgesic patch which is used for relieving pain in the process of intravenous infusion. The patch comprises a polyurethane transparent film and an absorbent pad fixed on the polyurethane transparent film, wherein the analgesic liquid medicine soaked in the absorbent pad is formed by mixing a nitroglycerin solution the mass percent concentration of which is 2-3% and a lidocaine hydrochloride solution the mass percent concentration of which is 0.5-1.5%, and the volume ratio of the nitroglycerin solution to the lidocaine hydrochloride solution is (2.5-3.5):1. When a patient is treated by intravenous infusion of medicaments such as potassium chloride and the like, the analgesic patch can effectively relieve the pain caused by infusion of the medicaments and has higher safety in clinical application.

Description

technical field [0001] The invention relates to an external medicine, in particular to an infusion drug pain-relieving patch for relieving pain during intravenous infusion. Background technique [0002] Intravenous infusion of potassium is widely used in clinical intravenous infusion, especially for fasting patients, a certain amount of intravenous potassium supplementation every day is a clinical treatment that must be adopted. However, drugs such as potassium chloride are more irritating to local skin and tissue, and can cause phlebitis with obvious pain. Because potassium ions are pain-inducing factors, after potassium chloride is infused into the body, in addition to its own physical stimulation, it can still cause the increase of nerve mediators in the body such as adrenal glands, 5-hydroxytryptamine and other substances to varying degrees, and induce pain reflexes, which reflect the degree of pain. Most of the nerves are accompanied by the venous channel for potassium...

However, drugs such as potassium chloride are more irritating to local skin and tissues, and can cause phlebitis with obvious pain

Because potassium ions are pain-inducing factors, after potassium chloride is infused into the body, in addition to its own physical stimulation, it can still cause the increase of nerve mediators in the body such as adrenal glands, 5-hydroxytryptamine and other substances to varying degrees, and induce pain reflexes, which reflect the degree of pain. Most of the nerves are accompanied by the venous channel for potassium supplementation, and their distribution is mainly located in the superficial surface of the vein, under the epidermis, and close to the surface of the end of the body. The larger the bundle area ratio of sensory nerves, the higher the pain sensitivity, and the more intense the pain caused. Moreover, the pain will be accompanied by the infusion, causing patients with persistent pain and fear, so a considerable number of patients cannot bear the pain of the infusion, which not only brings great pain to the patient, but also causes the drug to be unable to be injected on time and in accordance with the amount, delaying the patient's condition
