Embodiment Construction

[0011] The specific embodiments of the present invention are given below with reference to the accompanying drawings, which are used to further describe the structure of the present invention.

[0012] The thoracocentesis needle with a light source in this embodiment includes a puncture needle 1 and a drainage tube 2 connected thereto, and is characterized in that the tube wall of the puncture needle 1 is equipped with a light source 3, and the drainage tube 2 is provided with a control device 4, Prevent gas from entering the chest cavity causing a pneumothorax.

[0013] The front end of the drainage tube 2 is provided with a compression spring 5, and the front end of the compression spring is provided with a limiter 6, which controls the depth of the puncture needle entering the chest cavity by the elastic force of the compression spring to avoid injuring other tissues.

[0014] The structure of the thoracentesis needle with light source in this embodiment is scientific and r...

Abstract

The invention relates to a thoracocentesis needle for drainage of pleural effusions, particularly relates to a thoracocentesis needle with a light source and belongs to the technical field of medical apparatus structures. The thoracocentesis needle comprises a puncture needle head and a drainage tube connected with the needle head. The thoracocentesis needle is characterized in that a luminous source is arranged on the outside of the tube wall of the puncture needle head, and a control unit is arranged on the drainage tube to prevent air from entering the thoracic cavity to cause aerothorax. By means of the luminous source arranged on the outer side wall of the puncture needle head, an operator can observe the extraction condition of the pleural effusions; due to the control unit on the drainage tube, air can be prevented from entering the thoracic cavity to cause aerothorax; meanwhile, the depth of the puncture needle head into the thoracic cavity is convenient to control, the operation is accurate and safe, and the thoracocentesis needle is convenient and practical.

Description

technical field [0001] The invention relates to a thoracentesis needle with a light source, belonging to the technical field of medical device structures. Background technique [0002] Thoracentesis is a commonly used clinical method for diagnosing and treating diseases. If fluid is found in the patient's pleural cavity, the fluid can be extracted through thoracentesis for various examinations to find the cause of the disease; if there is a lot of fluid in the cavity, If the lungs are compressed or the effusion lasts for too long, the fibrin in it is likely to be organized and two layers of pleural adhesions will occur, which will affect the respiratory function of the lungs. It is necessary to puncture to remove the effusion, and if necessary, inject drugs to achieve the purpose of treatment. For encapsulated pleural effusions, although the existing thoracentesis needles can be combined with X-ray and ultrasound positioning for puncture, the adhesion bands or benign package...
