Description
Technical Field
The utility model relates to a thorax field, concretely relates to thorax puncture closed drainage device.
Background
Closed thoracic drainage is a drainage tube with one end placed in the thoracic cavity and the other end connected to a water-sealed bottle at a lower position to discharge air or collect fluid in the thoracic cavity, so that lung tissues are re-opened to restore functions. The traditional Chinese medicine composition is widely applied to drainage of blood chests, pneumothorax and empyema and after thoracotomy as a treatment means, and plays an important role in treating diseases.
The existing closed drainage tube for placing the thoracic cavity is used for separating subcutaneous tissues and muscles by using separating forceps and entering the thoracic cavity after skin is cut, so that the method not only increases the pain of a patient, but also has relatively long tube placing time and is inconvenient for long-term use.
Meanwhile, when the existing drainage device is used, the outer end of the drainage tube is inserted into the chest, so that the drainage device is inconvenient for a patient to move, and the drainage tube is easy to touch or pull to cause discomfort of the patient when the drainage device is used.
Therefore, a new type of chest drainage device is urgently needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the current drainage device easily causes the discomfort of the patient when in use, the service efficiency is lower, and the aim is to provide a thoracocentesis closed drainage device, solve the problem of the use of the drainage device.
The utility model discloses a following technical scheme realizes:
the puncture needle comprises a drainage tube and a puncture needle sleeved in the drainage tube, wherein a through hole is formed in the side face of one end of the drainage tube, one end of the puncture needle is a three-diamond puncture end, and the other end of the puncture needle is a handle end;
when puncturing, the puncture needle is sleeved in the drainage tube, and the puncture end is guided by the puncture to drive the drainage tube to enter the thoracic cavity through the chest wall.
The puncture needle is sleeved in the drainage tube, and the drainage tube is driven by the puncture end to enter the thoracic cavity from the chest wall; the puncture needle is sleeved in the drainage tube, after the puncture point is locally anaesthetized, the skin is cut for 1cm, then the drainage tube sleeved with the puncture needle is used for directly puncturing the chest wall to break through the pleura and enter the thoracic cavity for 0.5 cm. The puncture needle is withdrawn while the drainage tube is fed into the thoracic cavity by a proper length (10-12cm), the drainage tube is clamped before the puncture needle is completely withdrawn, after the puncture needle is pushed, a prepared closed drainage bottle is connected, and the drainage tube is fixed at a proper position of the chest wall by a fixing application, so that the closed thoracic drainage is completed.
Furthermore, a hose section is arranged in the drainage tube, and the distance between the hose section and one end of the drainage tube inserted into the thoracic cavity is 10 cm. An elastic spring sheet is arranged in the hose section, one end of the elastic sheet is connected with the inside of the drainage tube, and the other end of the elastic sheet is bent towards the inside of the drainage tube;
when the puncture needle is sleeved in the drainage tube, the elastic sheet is contacted with the outer side surface of the puncture needle, and when the puncture needle is arranged outside the drainage tube, the other end of the elastic sheet bends towards the inside of the drainage tube. The hose section is made of silica gel material.
When the pjncture needle withdrawed from the hose section, can buckle at hose section department to this device drainage tube outside the thorax, after buckling, the hose section is the bending form, at this moment, the drainage tube is after buckling in the one end outside the thorax, can be for the state that is parallel to each other with patient's skin surface, at the in-process that uses like this, more be favorable to other operations, avoid in the use, take place to pull to the drainage tube outside the thorax, further increase patient's discomfort and misery, the availability factor is lower.
