Adsorption conduction device of residual harmful ingredient after removing intracranial hematoma

Abstract

The invention relates to an adsorption drainage device for residual harmful composition after the clearance of intracranial hematoma, which includes a tee body, a drainage catheter and a plurality of adsorbent tubes of different materials. The main body of the tee body is hollow tube shape, the back end of the tee body is provided with internal threads, and a drainage port is arranged on the lateral part of the back end. The drainage catheter is connected with the drainage port of the tee body. The adsorbent tube is arranged in the hollow tube of the main body of the tee body, and the exposing part at the front end of the adsorbent tube is a semicircular sacculus which is loaded with RPPGF polypeptide, complement component monoclonal antibody and ZnPP in a way of mixing. The back end of the absorbent tube is matched with the internal threads at the back end of the tee body by external threads. Therefore, the absorbent tube is fixed in the tee body. The outer diameter of the adsorbent tube is smaller than the inner diameter of the tee body, and a space for liquid to flow to the drainage catheter is arranged between the adsorbent tube and the tee body. The back end of the adsorbent tube is sealed with a cap without a hole. The adsorption drainage device can be used for being matched with a hematoma grinding puncture needle and be used after a minimally invasive hematoma removing operation and provides an instrument which effectively drains the residual harmful compositions for the hemorrhage hematoma clearance operation. The adsorption drainage device is applied to neurology, neurosurgery, emergency department, etc. for the therapy of intracranial hematoma.

Description

technical field [0001] The invention relates to an adsorption and drainage device for residual harmful components after intracranial hematoma is removed, and in particular to a thrombin, complement and heme oxygenase-1 containing residual harmful components after intracranial hematoma is removed. adsorption drainage device. Background technique [0002] Cerebral hemorrhage is a common neurological emergency, which endangers the life of patients in severe cases and leaves neurological deficits in mild cases. The acute nerve injury caused by cerebral hemorrhage is not only due to the mass effect of the hematoma and the direct damage of the hematoma to the surrounding brain tissue, but also the secondary injury caused by the hematoma components is also the main cause of hemorrhagic brain injury. Secondary injury mainly includes secondary brain injury caused by thrombin, hemoglobin decomposition products, and complement in blood. After cerebral hemorrhage, the excessive thromb...

AI Technical Summary

Problems solved by technology

At present, various intracranial hematoma minimally invasive evacuation techniques used clinically to treat cerebral hemorrhage can relieve hematoma compression, improve circulation, reduce brain damage, and have certain significance for improving the success rate of treatment and postoperative neurological function recovery. Reason: Surgery is often performed 5-8 hours after the onset of cerebral hemorrhage, and the hematoma cannot be completely removed. After the operation, only simple physical drainage is performed, and it is not effective to remove the residual harmful components such as thrombin, complement, and heme oxygenase-1. Drain out
