Disposable pericardium chest puncture needle

Abstract

The invention discloses a disposable pericardium chest puncture needle which comprises a needle core, a drainage catheter and a drainage catheter joint chair. The needle core is arranged in the drainage catheter, a drainage cavity is arranged in the drainage catheter joint chair, the drainage cavity is internally provided with a rubber block, the needle core extends toward the drainage catheter joint chair and passes through the rubber block, one end of the needle core is provided with a needle core joint base which is hermetically matched with the drainage catheter joint chair, and the drainage catheter joint chair is provided with a side drainage tube which is provided with a three-way control device. According to the disposable pericardium chest puncture needle provided by the invention, during puncture and drainage, the puncture needle can retreat to prevent the tip from damaging heart and lug tissues. A gas one-way valve and an emergency end cover on the side drainage tube can be used as an emergent rescue tool for patients with severe tension pneumothorax. The three-way control device and the three-way side interface are arranged on the side drainage tube. The switch effect can be performed by the three-way control device as well as puncture and drainage of hydropericardium and pleural effusion and pericardium and chest injection of medication can be performed.

Description

technical field [0001] The invention relates to a medical needle, in particular to a disposable pericardial thoracentesis needle. Background technique [0002] Pericardial effusion, pleural effusion and spontaneous pneumothorax are common medical diseases. In most cases, pericardial and pleural effusions must be examined and drained for definitive diagnosis and treatment. Spontaneous pneumothorax is usually divided into closed pneumothorax, communicating pneumothorax, and tension pneumothorax according to the different situations of visceral pleura rupture and the impact on intrathoracic pressure after pneumothorax occurs. The treatment of spontaneous pneumothorax includes conservative treatment, suction or chest drainage, and surgical treatment. In most cases, suction or closed drainage is required. When a patient has poor lung function or a large number of pneumothorax, especially tension pneumothorax, effective closed drainage treatment of pneumothorax must be carried o...

Problems solved by technology

Clinically, due to the fear of needle tip damage to the heart or lung tissue, the relevant drainage can only be terminated early, making the drainage of pericardial effusion, pleural effusion or pneumothorax incomplete

[0004] The Chinese patent with the publication number CN101259029A discloses a disposable chest drainage needle. The drainage needle is provided with a cavity in the drainage catheter socket, and the drainage catheter is provided with a side connected to it and extended to the outside world and communicated with the drainage catheter. Drainage catheter, the end of the side drainage catheter connected to the drainage catheter socket is at the front end of the cavity, the tail end of the side drainage catheter is provided with at least one interface, and the interface is provided with an emergency end cover connected to it. The emergency end cover is a single Gas valve, this kind of puncture needle is not easy to go along the upper intercostal blood vessels when puncturing, and the gas is exhausted quickly, but there is no special control mechanism on the side drainage catheter of the drainage needle, so it is not easy to control the drainage of the effusion during drainage

In addition, this patented product cannot observe whether it is inserted in the exact position, and does not use the observation protection of medical staff.
