Constant-pressure anti-coagulation animal blood sampling bag

Abstract

The invention belongs to the field of medical instruments, and particularly relates to a constant-pressure anti-coagulation animal blood sampling bag. The bag comprises a bag body and blood sampling tube, a blood sampling needle is mounted on the blood sampling tube, two blood sampling cylinders are mounted on the bag body, the lower end of the blood sampling tube is communicated with the bag bodythrough a blood transfusion tube; the upper ends of the blood sampling cylinders are communicated with the blood sampling tube, a sliding plug is horizontally sealed and slides in the blood cylinders, the two blood sampling cylinders are fixed through a transversely-arranged driving cylinder arranged between the blood sampling cylinders, a vertical rotating shaft is arranged in the driving cylinder, a half gear is coaxially installed outside the rotating shaft, a movable frame is arranged on the inner wall of the driving cylinder in a sliding mode, a tooth groove is formed in the inner side wall of the movable frame, and the movable frame is arranged outside the half gear in a sleeving mode and engages with the half gear. The sliding plug can be driven to move back and forth by rotating arotating handle, the blood sampling speed is increased, compared with a traditional pressing reset mode, stimulation to animals is obviously reduced, injuries to the animals are reduced, and safe andefficient blood sampling operation is facilitated.

Description

technical field [0001] The invention belongs to the field of medical appliances, in particular to a constant pressure anticoagulation animal blood collection bag. Background technique [0002] Blood collection bag is a commonly used blood collection device, which is often used for animal blood collection testing. It is widely used because of its convenient use and simple operation. During the process of animal blood collection, animals tend to struggle and twist, resulting in slow blood collection speed and affecting blood testing. progress, so the existing animal blood collection bags are equipped with a power-assisted mechanism, which accelerates the flow of blood in the blood collection tube by pressing and resetting. Fast and slow times stimulate the animals, which not only increases the damage to the animals, but also causes the animals to struggle and twist more easily, causing safety problems. [0003] For this reason, we propose a constant pressure anticoagulant ani...
