Transfusion extravasation alarm

Abstract

The invention discloses an infusion solution leak alarm which comprises an elastic band, a flexible strap and fasteners and is characterized in that the flexible strap under the elastic band is internally provided with a buzzer, an electric chip, a cell and a touch switch, wherein, the electric chip, the cell and the touch switch are connected in series; an insulator is arranged on the flexible strap and both ends of the flexible strap are provided with fasteners. Before use, the insulator on the flexible strap is inserted in the middle of the touch switch; and when in use, the infusion solution leak alarm is covered on an infusion needle and the fasteners are buckled according the condition of an infusion part. Once the infusion solution leaks and partial skin swells subsequently, the insulator on the flexible band is then be separated from the touch switch which is then electrified and the buzzer gives an alarm as a result. The infusion solution leak alarm has the advantages that since the alarm is fixed on a part to be punctured, when the solution leaks at the part to be punctured, the alarm can sense the abnormal change in height and area of partial skin in a short time due tothe solution leakage, so as to give an alarm for prompt attention.

Description

technical field [0001] The invention relates to a medical device, in particular to a transfusion extravasation alarm. Background technique [0002] At present, it is known clinically that children, the elderly, drowsiness, patients with insensitivity such as postoperative anesthesia or unaccompanied patients, or patients who are rarely ill and lack infusion experience, etc., often cannot detect infusion extravasation in time. In one case, it will cause local swelling, pain and discomfort, and in severe cases, local skin necrosis and other serious consequences will be caused due to excessive hypertonic or irritating drugs leaking out of the blood vessels. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art. The invention provides a transfusion extravasation alarm, which has a simple structure and is convenient to use. [0004] The technical solution adopted by the present invention to solve the technical problems is: a...
