A kind of multi-chamber drug-free airtight aseptic injector

Abstract

The invention provides a multi-chamber dosage-free airtight sterile medicine injector and belongs to the field of medical apparatuses and instruments. The multi-chamber dosage-free airtight sterile medicine injector is in a shape of a flying saucer and is divided into four to eight same-sized sector spaces, each space is divided into two chambers, a round shared space is located at the position of the circle center, the center of the medicine injector is connected with a thin silicone tube, and the far end of the silicone tube is connected with a drainage tube at an operative site. Weak easily-opened areas are arranged among the medicine storage chambers and between the medicine storage chambers and the round shared space. A C-shaped magnet matched with the round shared space in size is arranged on the outer side of the two-layer bag wall of the round shared space and is attracted with a round irony plate to seal the two-layer bag wall, and a gap of the C-shaped magnet is aligned to the weak easily-opened areas between the sector spaces prepared for medicine injection and the round shared space and accordingly serves as a unique channel of the center thin silicone tube for the sector spaces prepared for medicine injection and the round shared space. The multi-chamber dosage-free airtight sterile medicine injector can achieve multi-time dosage-free medicine injection under the airtight sterile condition, avoids the possibility that the medicine in the dosage process is polluted by microorganisms and obviously reduces occurrence rate of lethal intracranial infection.

Description

technical field [0001] The invention relates to a medical device, in particular to a drug injector. Background technique [0002] At present, the number of hypertensive patients in our country has reached 200 million. At the same time, with the transformation of society towards aging, people's life expectancy is generally extended, and hypertensive cerebral hemorrhage has become a common and frequently-occurring disease. The disease has three high characteristics of high morbidity, high mortality and high disability. Moreover, in hypertensive cerebral hemorrhage, about 80% of the intracranial hemorrhage occurs in the basal ganglia, which is the place where important nerve center conduction fibers pass. Therefore, hypertensive cerebral hemorrhage often causes patients to die or become disabled. In the past, craniotomy was often used clinically for hypertensive cerebral hemorrhage, which caused brain tissue damage to varying degrees while removing intracerebral hematoma. , t...

AI Technical Summary

Problems solved by technology

Every time the intracranial drainage tube is opened and urokinase is injected, bacteria may be brought into the brain through the drainage tube, resulting in intracranial infection

Moreover, blood clots in the brain are the best bacterial culture medium. Once an intracranial infection occurs, the mortality and disability rate of the patient will be significantly increased.
