Description
Technical field
This utility model relates to a kind of anti-pneumothorax thoracentesis needle.
Background technology
Pneumothorax refers to that gas enters pleural space, causes pneumatosis state, is called pneumothorax.How because pulmonary disease or external force impact make lung tissue and visceral pleura break, or the trickle edema due to disorder of QI follicular rupture near lung surface, in lung and bronchus, air escapes into pleural space, one of primary disease Shu Fei section emergency case, and severe patient can threat to life, should treat in time;
Current pleurocentesis is the technology that clinical treatment is often applied, but general thoracentesis needle tip needle tubing, often can cause the situation that lungs are punctured in the treatment, and then cause pneumothorax complication;
Through long-term clinical treatment experience and analysis and summary except a kind of not only can be separated enter shape thoracentesis but also avoid damaging the novel thoracentesis needle of lungs as much as possible.
Summary of the invention
This utility model provides a kind of anti-pneumothorax thoracentesis needle for the deficiencies in the prior art, and object solves existing thoracentesis needle easy damage lungs in clinical treatment to be punctured, and then cause the problem of pneumothorax complication.
This utility model is for realizing above object, adopt following scheme: a kind of anti-pneumothorax thoracentesis needle, comprise needle tubing, inner core tube, baffle plate, external screw thread nut, spring and spring pedestal, the syringe needle of described needle tubing is tip, afterbody consolidation nut, described inner core tube is hollow structure, its leading head is circular blunt nosed, side, front end is provided with side opening, described inner core tube afterbody is provided with baffle plate successively to head, external screw thread nut, spring and spring pedestal, described baffle plate is welded on described inner core tube afterbody, described external screw thread nut and spring housing are connected in described inner core tube, described spring pedestal screw thread is screwed in described inner core tube, described external screw thread nut and described its thread spin.
Preferably, described external screw thread nut is that threaded open-end tube is established on surface, and described inner core tube is provided with the strip projection for connecting and fixing with the opening part of described external screw thread nut.
Preferably, described inner core tube length is 4.5cm, and described needle tubing is 4cm.
Preferably, described needle tubing, spring, inner core tube, spring pedestal and external screw thread nut all adopt medical stainless steel material.
The beneficial effects of the utility model: project organization of the present utility model is reasonable, perform the operation easy to use, safe and reliable, the pointed syringe needle of needle tubing is used for prick skin, intercostal tissue, parietal pleura, enter pleural space, the head of inner core tube is arranged to the circular blunt nosed spring that first can utilize when running into the resistances such as skin and is realized the contraction in needle tubing, secondly when behind arrival thoracic cavity, because resistance reduces, spring in inner core tube is upspring, circular blunt nosed can preventing punctures thoracic cavity film and its hetero-organization, the side opening that rear inner core tube head side surface part talked by spring stretches out needle tubing, now by extracting pleural fluid.

Detailed description of the invention
A kind of anti-pneumothorax thoracentesis needle as illustrated in the drawing, comprise needle tubing 1, inner core tube 3, baffle plate 8, external screw thread nut 7, spring 2 and spring pedestal 6, the syringe needle of described needle tubing 1 is tip, afterbody consolidation nut 4, described inner core tube 3 is hollow structure, its leading head is circular blunt nosed, side, front end is provided with side opening 5, described inner core tube 3 afterbody is provided with baffle plate 8 successively to head, external screw thread nut 7, spring 2 and spring pedestal 6, described baffle plate 8 is welded on described inner core tube afterbody, described external screw thread nut 7 and spring 2 are socketed in described inner core tube 3, described spring pedestal 6 screw thread is screwed in described inner core tube, described external screw thread nut 7 spins with described nut 4 screw thread, described external screw thread nut 7 is for establishing threaded open-end tube in surface, described inner core tube 3 is provided with the strip projection 9 for connecting and fixing with the opening part of described external screw thread nut 7, described inner core tube 3 length is 4.5cm, described needle tubing 1 is 4cm., described needle tubing 1, spring 2, inner core tube 3, spring pedestal 6 and external screw thread nut 7 all adopt medical stainless steel material.
Embodiment, the assembling of this device, first by the corresponding clamping of the opening part of external screw thread nut 7 with the strip projection 9 of inner core tube 3 outer wall, then external screw thread nut 7 is slidably socketed in inner core tube 3, now strip projection 9 is fixed on the opening part of external screw thread nut 7, prevent from rotating and use China and foreign countries' screw nut 7 to overturn, spacing by baffle plate 8 bottom described external screw thread nut 7, then spring 2 is socketed, described spring 2 afterbody is against external screw thread nut 7 front end, so to spin described spring pedestal at screw thread again, be used for the position of restraining spring 2, re-using inner core tube 3 is connected in described needle tubing 1 through spiro cap, the external screw thread of external screw thread nut 7 is utilized to spin the nut 4 of described needle tubing 1 afterbody, namely the assembling of this device is completed after described nut 4 screws, after assembling, inner core tube 3 head and side opening 5 stretch out needle tubing 1 head,
The resistance that in use circular blunt nosed inner core tube 3 runs into the tissue such as skin is shunk by spring 2 and enters needle tubing 1, utilize the pointed syringe needle of needle tubing 1 for skin puncture intercostal tissue, parietal pleura, after entering pleural space, inner core tube 3 meets obstructions and weakens, now spring 2 is upspring, make inner core tube 3 head and side opening 5 stretch out needle tubing 1, utilize side opening 5 to extract hydrops in pleural space.
