Description
Technical field
The invention belongs to technical field of medical equipment more particularly to a kind of tumour ponding flow diverters of internal-circulation type pressure stabilizing.
Background technique
Due to the pathological effect of tumour, often there is the phenomenon that abdomen of tumor patient or thoracic cavity internal water accumulation, can pass through
It pierces through art and extracts to drain from patient's body by tumour ponding, speed is slowly a small amount of when extracting ponding, general once to take out abdomen
Water is big or draws water too fast, abdominal pressure can be made to strongly reduce, lead to other of short duration position ischemics, thus to recycle it is progressive,
Otherwise it will lead to patient's syncope even to suffer a shock, but be all at present to be drained the ponding of patient's body by simple needle tubing
Come, extract speed and extraction amount leans on medical staff by virtue of experience to judge entirely, therefore there is certain errors, for newly upper hand
Medical staff for, operation difficulty is larger, and there is certain risks, all causes unfavorable shadow to patient and medical staff
It rings.
Then, in view of this, being studied improvement for existing structure and missing, a kind of internal-circulation type pressure stabilizing is provided
Tumour ponding flow diverter, to achieve the purpose that with more more practical value.
Summary of the invention
