Abstract
A subpressure pleuroperitoneal cavity puncture remaining needle consists of an indwelling catheter, a rubber stopper, a puncture needle, an injector port, a one-way valve and a subpressure drain tube, wherein the tail end of the indwelling catheter is internally provided with the rubber stopper; the outer wall of the indwelling catheter is provided with scales; the rear end of the indwelling catheter is provided with the injector port; the front of the injector port is provided with the one-way valve to prevent pneumothorax risk from happening to patients who come home after implanted with a catheter during outpatient service; and the indwelling catheter is internally provided with the puncture needle and the rear end of the puncture needle is connected with a subpressure drain tube. When the subpressure pleuroperitoneal cavity puncture remaining needle is used to conduct thoracocentesis, the needle head penetrates through parietal pleura; when the needle head reaches the position of effusion, the effusion enters a subpressure tube under the attraction of subpressure; and accordingly, medical personnel can see the effusion immediately and then stop entering to ensure puncture safety. The subpressure pleuroperitoneal cavity puncture remaining needle is simple in structure, convenient for use, safe and reliable.
Description
Technical field:
This utility model relates to medical apparatus and instruments, relates in particular to a kind of negative-pressure type splanchnocoel puncture remaining needle.
Background technology:
Hydrothorax is a kind of comparatively common disease, at present, often adopts the method treatment of thoracentesis and closed drainage; but at present in clinical treatment; when regular meeting appears at thoracentesis,, cause puncturing visceral pleura and alveolar and cause the pneumothorax complication owing to thrust deeply.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, provides a kind of simple in structure, easy to use, can effectively avoid puncturing the negative-pressure type splanchnocoel puncture remaining needle of visceral pleura.
Negative-pressure type splanchnocoel puncture remaining needle described in the utility model relates to by inlying catheter, rubber closure, puncture needle, syringe interface, check valve and negative-pressure drainage tube and forming.Said inlying catheter is the main element of negative-pressure type splanchnocoel puncture remaining needle described in the utility model, be the software hollow form, terminus inner at inlying catheter is provided with rubber closure, also be provided with puncture needle in the said inlying catheter, said puncture needle is under non-working condition, pass rubber closure, enter in the conduit, the inlying catheter outer wall is provided with scale, the rear end of inlying catheter is provided with syringe interface, the front of syringe interface is provided with check valve, pneumothorax danger occurs to prevent the patient after the outpatient service implantation catheter is gone home.In said inlying catheter, be provided with puncture needle, the rear end of puncture needle is connected with negative-pressure drainage tube, said negative-pressure drainage tube is identical with negative pressure pipe conduit with the blood drawing of prior art, end is the sharp needle form, when using negative-pressure type splanchnocoel described in the utility model to puncture remaining needle, the terminal negative pressure pipe that inserts of negative-pressure drainage tube is got final product.
Use negative-pressure type splanchnocoel puncture remaining needle described in the utility model, when carrying out thoracentesis, syringe needle passes parietal pleura, when reaching the hydrops position, hydrops can enter the negative pressure pipe under vacuum suction, medical personnel can see hydrops immediately, and stop to continue deeply, to guarantee puncture safety, negative-pressure type splanchnocoel puncture remaining needle described in the utility model, simple in structure, easy to use, safe and reliable.
