Abstract
The invention discloses a medical remaining thoracic cavity puncture needle which is provided with a needle head cannula, a puncture needle body, a cannula seat, a rubber plug, a puncture needle handle and a drainage tube. A scale is arranged on the surface of the needle head cannula 1, a side hole is formed in the front end of the needle head cannula, the rear end of the needle head cannula is fixed to the cannula seat, the puncture needle body is fixed to the puncture needle handle and penetrates through the rubber plug and the needle head cannula, a slope needle head is exposed through the front end of the needle head cannula, the side face of the cannula seat is connected with the drainage tube, two Y-shaped tail ends of the drainage tube are provided with heparin caps for closing drainage channels, and the two Y-shaped drainage channels of the drainage tube are used for drainage and internal thoracic cavity medicine injection respectively. Due to the adoption of the needle head cannula with the scale and the side hole, the puncture needle can puncture to the accurate locating depth, the cannula is a hose, a blunt head is arranged at the front end of the cannula, the occurrence rate of pneumothorax is greatly reduced, water can be extracted or medicine can be applied multiple times by fixing the needle head cannula, water or air can be fully extracted through the side hole formed in the needle head cannula, and the needle head cannula can be prevented from being blocked by sticky matter.
Description
technical field:the present invention relates to medical apparatus and instruments, be directly involved in a kind of medical retention thoracentesis needle.
background technology:thoracic cavity, peritoneocentesis are operation of diagnosis and treatment common clinically, thoracentesis needle ready-made is at present without graduation indication, when causing thoracentesis, depth of needle is not easy to grasp, inserting needle is crossed and is deeply easily punctured visceral peritoneum generation pneumothorax, repeated localised puncture will increase infection probability and patient suffering, and when hydrothorax is sticky, also easy blocking pipe causes drawing liquid failure.
summary of the invention:object of the present invention will provide a kind of medical retention thoracentesis needle exactly, and when effectively can solve thoracentesis to a certain extent, depth of needle does not allow wield problem.
The object of the present invention is achieved like this: a kind of medical retention thoracentesis needle, there is needle sleeve 1, puncture needle 2, casing seat 6, rubber stopper 7, puncture needle handle 8 and drainage tube 9, needle sleeve 1 surface is provided with scale 4, needle sleeve 1 front end is provided with side opening 3, needle sleeve 1 rear end is fixed on casing seat 6, puncture needle 2 is fixed on puncture needle handle 8, puncture needle 2 exposes bevel needle through rubber stopper 7 and sleeve pipe 1 in needle sleeve 1 front end, casing seat 6 side is connected with drainage tube 9, two Y type ends of drainage tube 9 are provided with calparine cap 10 closed drainage passage, two Y type drainage channels of drainage tube 9 are respectively used to drain and intrapleural injection.
The present invention is owing to have employed with a scale and needle sleeve that is side opening, accurate emplacement depth can be punctured to, and sleeve pipe is flexible pipe and front end is blunt nosed, significantly reduce the incidence rate of pneumothorax, can repeatedly be drawn water or administration by fixed needle sleeve pipe, the side opening that needle sleeve is provided with can draw water or gas fully, and can prevent dope from blocking sleeve pipe.
accompanying drawing illustrates:accompanying drawing is structure principle chart of the present invention, and below in conjunction with accompanying drawing, the invention will be further described.
detailed description of the invention:accompanying drawing shows a kind of medical retention thoracentesis of the present invention needle construction, there is needle sleeve 1, puncture needle 2, casing seat 6, rubber stopper 7, puncture needle handle 8 and drainage tube 9, needle sleeve 1 surface is provided with scale 4, needle sleeve 1 front end is provided with side opening 3, needle sleeve 1 rear end is fixed on casing seat 6, puncture needle 2 is fixed on puncture needle handle 8, puncture needle 2 exposes bevel needle through rubber stopper 7 and sleeve pipe 1 in needle sleeve 1 front end, casing seat 6 side is connected with drainage tube 9, two Y type ends of drainage tube 9 are provided with calparine cap 10 closed drainage passage, two Y type drainage channels of drainage tube 9 are respectively used to drain and intrapleural injection.
When using the present invention to puncture, when puncture needle 2 thrusts emplacement depth, pull back puncture needle handle 8, when rubber stopper 7 moved to by puncture needle 2, observe in passage 5 and whether have liquid to flow out, can judge whether puncture needle front end arrives hydrops position.
