Abstract

The invention belongs to the technical field of biology and medicine, and particularly relates to a puncture needle for a pleural cavity of a rabbit. The puncture needle for the pleural cavity of the rabbit mainly solves the problems that an existing puncture needle for the pleural cavity of the rabbit is prone to being blocked and cannot be fixed. According to the technical scheme, the puncture needle for the pleural cavity of the rabbit comprises a silicone tube I, a silicone tube II, a puncture needle body, a three-way pipe, a water manometer, a fixing ring and a syringe, the puncture needle body is mounted at one end of the silicone tube I, the other end of the silicone tube I is connected with one port of the three-way pipe, another port of the three-way tube is connected with one end of the silicone tube II, the other end of the silicone tube II is communicated with the water manometer, the syringe is arranged on the third port of the three-way pipe, the needle tip of the puncture needle body is of an inclined plane structure, the upper portion of the puncture needle body is of a threaded structure, the fixing ring is arranged on the upper portion of the puncture needle body and is matched with the threaded structure, and multiple side holes are formed in the periphery of the lower portion of the puncture needle body. The puncture needle for the pleural cavity of the rabbit mainly has the advantages of being free of blocking and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of biology and medicine, and in particular relates to a rabbit pleural cavity puncture needle. Background technique [0002] Pleural puncture is a necessary operation for rabbit respiratory system experiments in the teaching and scientific research of medical functional science, and the thoracentesis needle is the basic device for detecting the intrapleural pressure of rabbits in physiological and pathological models. The traditional rabbit pleural cavity puncture needle is designed with a flat head and the needle diameter is small. After penetrating the chest wall muscle during operation, the needle is easily blocked by tissue or blood clots, so the intrapleural pressure cannot be recorded. Repeatedly adjust the needle point The position of the puncture needle will cause intrathoracic hemorrhage and pneumothorax in the experimental animals, which will lead to the failure of the experiment; because the punct...
