Self-balancing intracranial perfusion device

Abstract

The invention provides a self-balancing intracranial perfusion device, and relates to the field of medical lavage devices. The self-balancing intracranial perfusion device comprises a liquid injectionpot, a perfusion guide pipe and a liquid storage tank which communicate pairwise through a pipeline, wherein the perfusion guide pipe comprises an inner pipe and an outer pipe sleeving the inner pipe, two ends of the outer pipe are blocked to form a cavity, and a plurality of side holes communicating with the cavity are formed in the side wall of the front section of the outer pipe and the cavitycommunicates with the liquid storage tank through a pipeline, one end of the inner pipe communicates with the liquid injection pot through a pipeline, the other end of the inner pipe communicates with the cavity, lesions can be subjected to continuous and stable lavage through effective communication of all lavage elements, the pressure balance control effect exists, local lavage liquid accumulation is avoided, and the stable medicine concentration can be kept. In addition, the system is always in a closed state during working, so that the infection risk is reduced, and the effects of good perfusion and drainage effects, safety, effectiveness and labor saving are achieved.

Description

technical field [0001] The disclosure relates to the field of medical irrigation devices, in particular to a self-balancing intracranial perfusion device. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Drilling and drainage for some intracranial lesions is one of the common surgical methods in neurosurgery, which has the advantages of minimally invasive, convenient and effective. Such lesions mainly include intracerebral hematoma, brain abscess, ventricular hemorrhage or empyema, etc. In the past, it was usually necessary to intermittently inject drugs into such lesions (or lesions) through the drainage tube to improve the therapeutic effect. Flush the abscess cavity with normal saline of other drugs to promote the resolution of inflammation, and flush the hematoma cavity with normal saline containing urokinase and other drugs to promo...

AI Technical Summary

Problems solved by technology

[0004] The inventors found that the current flushing operation requires medical staff to open the drainage tube system multiple times, and even if the injection and suction are performed slowly during each flushing, a relatively large pressure fluctuation will be generated in a short period of time on the local lesion, which will easily cause brain tissue damage, It is easy to cause excessive extravasation of medicinal liquid, or even extravasation of inflammatory fluid beyond the abscess cavity, resulting in unnecessary damage to adjacent brain tissue;

[0005] In addition, due to intermittent manual injection or flushing, it is not only cumbersome and labor-intensive, but also requires an intermittent open drainage system to increase the risk of infection, and it is also impossible to maintain a local stable drug concentration and lavage pressure gradient, resulting in poor lavage and drainage effects and reduced It is difficult to meet the existing demand for flushing treatment
