Animal bronchus alveolus irrigation solution obtaining device

Abstract

The invention discloses an animal bronchus alveolus irrigation solution obtaining device, and relates to the technical field of medical experiment devices. The device comprises a tee hose, a vacuum bottle, an injection syringe and an injection needle are connected to three ends of the tee hose respectively, and a first liquid stop clamp, a second liquid stop clamp and a third liquid stop clamp sleeve three branch pipes of the tee hose respectively. Accordingly, the injection syringe is only used for injecting an irrigation solution into the lung of an animal, and the vacuum bottle is only usedfor extracting liquid obtained after irrigation. An operator only needs to switch on or off the liquid stop clamps on the tee hose, injection and suction of the irrigation solution can be achieved, operation is easy, and the efficiency is high. In addition, a filtration device is arranged in the vacuum bottle, in the irrigation solution suction process, the irrigation solution is automatically filtered, filtration does not need to be additionally conducted, the operation steps are saved, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical experiment devices, in particular to a device for obtaining animal bronchoalveolar lavage fluid. Background technique [0002] Bronchoalveolar lavage examination is a relatively new lung disease examination method, mainly used in: lung infection; lung cancer and other malignant tumors; lung interstitial disease, when performing bronchoalveolar lavage examination, the lavage The final liquid is taken out from the alveoli of animals (mostly mice), which is convenient for testing and confirming the diagnosis result. [0003] In the past, when the laboratory performed bronchoalveolar lavage on small animals, intravenous indwelling needles or syringes were often used. The indwelling needle catheter or syringe needles were inserted into the animal's bronchus and ligated and fixed. The lavage fluid in the prior art is often PBS Or normal saline, and then use a syringe to inject the lavage fluid through ...

Problems solved by technology

[0004] In the above process, because there is no fixed and standardized device, the operation process is cumbersome. During the process, the syringe needs to be frequently removed from the hose or installed. When installing the syringe, it is necessary to keep the connection point between the syringe and the hose from leaking. High requirements for operating skills and low efficiency
