The invention relates to an external ventricular drainage and hematoma clearance device. The external ventricular drainage and hematoma clearance device includes a drainage tube, and a first drainageneedle and a second drainage needle which are connected to a head end and a tail end of the drainage tube respectively; a surface of an inner wall of the drainage tube is coated with an anticoagulantcoating; and a filtering device, a pressure application device and a three-way tube are successively arranged on a tube line of the drainage tube. The external ventricular drainage and hematoma clearance device can adopt different drainage manners according to the ventricular hematoma degree: for ventricular cast severe cerebral hemorrhage, the two drainage needles adopt transorbital puncture, puncture a lateral ventricle posterior horn, and adopt angle puncture and enter a ventricle, and a hematoma-lateral ventricle frontal horn drainage-purging in vitro-lateral ventricle posterior horn backflow circulation loop is established; and for mild ventricular hemorrhage, the first drainage needle and the second drainage needle are combined into a puncture needle, and a local circulation is established. The external ventricular drainage and hematoma clearance device can clear up ventricular blood clots, in particular ventricular cast, can effectively relieve secondary lesion such as hydrocephalus, encephaledema, and vasospasm due to ventricular hemorrhage and ventricular cast.

Fibrin glue vasodilation agent sustained-release long-acting composition

The present invention relates to a long acting composition of the fibrin glue vasodilating agent with sustained release property, which comprises a vasodilating agent and a spasmolysant of effective amount, fibrin glue that can delay the releasing of the vasodilating agent. The present invention is characterized in that the composition is a mixture of the fibrin glue and the vasodilating agent; the mixing concentration changes in the range from 0.1mg per ml to 10mg per ml according to various kinds of vasodilating agents. In the present invention, the long acting composition of the fibrin glue vasodilating agent with sustained release property has the following properties of good tissue compatibility, slow releasing of the drugs, long maintenance in the application area and reduction of the side effects to the human body. The present invention is applied in the control during surgery as well as the prevention and treatment after the surgery, which can cause the vasospasm attack. The present invention is particularly applied in the prevention and reduction of the convulsive seizure, which occurs in the coronary artery bypass grafting operation or after the operation. Therefore the pain of the patient is dramatically decreased and the cure rate is improved, and the recurrence is reduced.
