Abstract

The present invention relates to a jugular vein intubation drug delivery device for cerebral infarction, at least comprising an inner membrane for constituting a first accommodation cavity for containing medicine and a rigid semi-permeable body for water to flow through, the inner membrane and the semi-permeable body according to The means capable of forming a second receiving chamber for holding the osmotic agent are connected in a closed connection with each other. The sum of the volumes of the first accommodation chamber and the second accommodation chamber is defined by a rigid semi-permeable body, and the first accommodation chamber can change its shape or size to adapt to the osmotic pressure of the second accommodation chamber due to the presence of osmotic agent in the external environment Under the action of the semipermeable body entering the second accommodation cavity and combining with the osmotic agent, the change in shape or size is adjacent to each other with the flexible inner membrane as the boundary. Through the above-mentioned setting method, the device is used for jugular vein intubation administration of the rat cerebral infarction model, with less trauma, continuous and stable administration, and avoiding the trouble of administration on weekends and nights.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a jugular vein intubation drug delivery device for cerebral infarction. Background technique

[0002] Cerebral infarction is a disease that seriously endangers human health. At present, there is no more effective method except timely thrombolytic therapy within 4-5 hours of onset. Cerebral infarction in the elderly is a type of critical cerebrovascular disease. After the onset, it may lead to insufficient blood supply to the brain tissue, resulting in local brain tissue ischemia, hypoxic necrosis, affecting the patient's neurological function, and causing the patient to become conscious. , language, and physical impairments. In the process of treating elderly patients with cerebral infarction, the main method is intravenous thrombolysis, but the application effect of conventional intravenous infusion of thrombolysis is not ideal. Therefore, a better method of intravenous...
