Embodiment 1

[0019] Such as Figure 1-2 As shown, an anticoagulant animal blood pumping bag includes a bag body 1, a constant pressure tube 2 and a blood pumping tube 3 are connected to the bag body 1, and the constant pressure tube 2 is connected with the outside air to ensure constant pressure inside the bag and prevent blood backflow The problem occurs, the other end of the blood-drawing blood vessel 3 is equipped with a blood-drawing needle 4, and the inner wall of the blood-drawing blood vessel 3 is fixedly connected with a rotating ring 5. The rotating ring 5 is provided with an impeller 6 that can rotate around its axis. The impeller 6 includes a plurality of The fan blades 7 and the ends of the plurality of fan blades 7 that are far away from each other are all rotatably connected to the inner wall of the rotating ring 5 .

[0020] The side wall of the blood-drawing vessel 3 is fixedly connected with a negative-pressure cylinder 8 arranged perpendicular to its axial direction. The ...

Embodiment 2

[0024] Such as image 3 As shown, the difference between the present embodiment and the first embodiment is that the plurality of fan blades 7 are formed by a mesh plate, and a plurality of mesh holes 16 are equidistantly arranged on the mesh plate.

[0025] In this embodiment, when the blood normally flows in the pumping blood vessel 3, because there are a plurality of mesh holes 16 in the fan blade 7, part of the blood passes directly through the mesh holes 16, and the driving force on the fan blade 7 is relatively small. When the impeller 6 rotates slowly or even does not rotate, the anticoagulant does not enter the pumping blood vessel 3; when the blood coagulates to generate a blood clot, the blood clot fills the mesh 16 and blocks the mesh 16. At this time, the blood The driving effect of the flow on the fan blade 7 is significantly increased, driving the impeller 6 to rotate, and sucking the anticoagulant into the blood vessel 3, which is beneficial to the rational use ...

Abstract

The invention belongs to the field of blood drawing bags, and particularly relates to an anti-coagulation animal blood drawing bag. The anti-coagulation animal blood drawing bag comprises a bag body,a constant-pressure tube and a blood drawing tube communicate with the bag body, a blood drawing needle is installed at the other end of the blood drawing tube, a rotating ring is fixedly connected tothe inner wall of the blood drawing tube, an impeller capable of rotating around the axis of the rotating ring is arranged in the rotating ring, the impeller comprises a plurality of fan blades, theends, away from one another, of the plurality of fan blades are rotationally connected with the inner wall of the rotating ring, a negative pressure cylinder perpendicular to the axis direction of theblood drawing tube is fixedly connected to the side wall of the blood drawing tube, the negative pressure cylinder communicates with the blood drawing tube through a communicating tube, a piston plate slides in the negative pressure cylinder in a sealed mode, and the piston plate is fixedly connected with the lower bottom surface of the negative pressure cylinder through a reset spring. Blood canflow to push the impeller to rotate, an anti-coagulation agent is automatically sucked into the blood drawing tube to be mixed with the blood, blood coagulation and blockage are effectively avoided,blood drawing operation can be conveniently and rapidly conducted, and meanwhile harm to animals is reduced.

Description

technical field [0001] The invention belongs to the field of blood-drawing bags, in particular to an anti-coagulation animal blood-drawing bag. Background technique [0002] Many animal infectious diseases are zoonotic. Doing a good job in animal disease prevention and control is of great significance to protect the healthy development of the breeding industry and the safety of people's lives and property, and to prevent major regional animal epidemics and public health safety incidents. The construction of a big data platform , effectively solved the problem of difficult animal epidemic prevention. In the process of building a big data platform, it is necessary to use animal blood bags to draw blood for a large number of animals. [0003] In the actual blood collection process, the animals often struggle and twist, which affects the blood drawing operation of the medical staff, resulting in slow blood drawing speed, long time-consuming, long residence time of blood in the d...
