Abstract
The utility model discloses a closed-cycle perfusion system, comprising a liquid storage tank and a peristaltic pump that is connected with the liquid storage tank; the closely circulated perfusion system also comprises a damping tank, a first valve, a blood vessel flow field testing model, a second valve and a pressure tank, wherein each of the upper part and the lower part of the side wall of the damping trough is provided with an overflow hole; the damping trough is connected with the peristaltic pump by a pipeline; the overflow hole at the upper end of the damping trough is connected with the liquid storage tank by the pipeline; the overflow hole at the lower end of the damping trough is sequentially connected with the first valve, the blood vessel flow field testing model, the second valve and the pressure tank by the pipelines; a pressure meter is further connected between the first valve and the second valve; and a water drainage pipe of the pressure tank is connected with the liquid storage tank by the pipeline. The damping tank can keep durable and fixed pressure in the system; the valve can control the flowing speed of the fluid and can prevent the fluid from flowing back; the pressure meter connected between the two valves can be used for testing the pressure difference between the inlet and the outlet of the model; and the perfusion system is simple in structure; and the variableness of the test is reduced.
Description
Technical field
The utility model relates to a kind of perfusion system of closed circulation.
Background technology
In the biological medicine experiment, often can use the perfusion system of closed circulation, especially in the test of simulation human body blood flow, the perfusion system of existing closed circulation generally is that fluid reservoir is connected with peristaltic pump, peristaltic pump directly is connected with test model, so not only be difficult to keep the pressure stability of whole system, be difficult to the flow velocity of controlling liquid, also be easy to flow backwards; And the pressure of import and outlet can reduce when flow of liquid was crossed test model, and existing perfusion system can not be measured this pressure reduction.
The utility model content
The purpose of this utility model just is to provide a kind of perfusion system of closed circulation, can keep the stable gas pressure of total system, makes things convenient for the flow velocity of controlling liquid, prevents to flow backwards, and can also measure the pressure differential of test model import and outlet.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of perfusion system of closed circulation, comprise fluid reservoir and coupled peristaltic pump, also comprise dashpot, first valve, blood vessel flow field test model, second valve and head tank, described dashpot side wall upper part and bottom are respectively arranged with a spillway, described dashpot is connected with peristaltic pump by pipeline, the spillway of described dashpot upper end links to each other with fluid reservoir by pipeline, the spillway of lower end connects first valve successively by pipeline, blood vessel flow field test model, second valve and head tank, also be connected with pressure gauge between described first valve and second valve, the rising pipe of described head tank inserts fluid reservoir by pipeline.
Compared with prior art, advantage of the present utility model is: the fixed pressure that continue of dashpot in can the maintenance system is set, valve is set can controls flow rate of fluid, can also prevent to flow backwards; Connect pressure gauge between two valves and can measure the pressure reduction of test model import and outlet, simple in structure, reduced the changeability of testing.
Description of drawings
Fig. 1 is the synoptic diagram of the perfusion system of closed circulation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment: referring to Fig. 1, the perfusion system of closed circulation, comprise fluid reservoir 1 and coupled peristaltic pump 2, also comprise dashpot 3, first valve 4, blood vessel flow field test model 6, second valve 5 and head tank 8, described dashpot 3 side wall upper part and bottom are respectively arranged with a spillway, described dashpot 3 is connected with peristaltic pump 2 by pipeline, the spillway of described dashpot 3 upper ends links to each other with fluid reservoir 1 by pipeline, the spillway of lower end connects first valve 4 successively by pipeline, blood vessel flow field test model 6, second valve 5 and head tank 8, the import of blood vessel flow field test model 6 is connected with first valve 4, also be connected with pressure gauge 7 between its outlet connection second valve, 5 described first valves 4 and second valve 5, the rising pipe of described head tank 8 inserts fluid reservoir 1 by pipeline.
During use, the fixed pressure that continue of dashpot 3 in can the maintenance system, two valves can be controlled flow rate of fluid, can also prevent to flow backwards; Connect pressure gauge 7 between two valves and can measure the pressure reduction of test model import and outlet, simple in structure, reduced the changeability of testing.
