Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
As shown in Figure 1, for the structural representation of the suction filtration machine for cardiovascular and cerebrovascular research and development of products of the utility model preferred embodiment, for a suction filtration machine for cardiovascular and cerebrovascular research and development of products, comprise vavuum pump 10, the Suction filtration device 20 of holding gas circuit to be connected of bleeding with vavuum pump 10; This suction filtration machine being used for cardiovascular and cerebrovascular research and development of products also comprise for detect vavuum pump 10 bleed end pressure detector 30, for controlling the controller 40 of vavuum pump 10 vacuum pressure; The signal detected for the treatment of described detector 30 by this signal feedback to the processor 50 of controller 40; Described detector 30 is connected to the end of bleeding of vavuum pump 10, and described controller 40 is connected with vavuum pump 10; Described processor 50 one end is connected with detector 30, and the other end is connected with controller 40.Wherein, described detector 30 is digital pressure vacuum gauge or electric contact pressure vacuum gauge.
Described Suction filtration device 20 comprises support 201, the reflux condensing tube 202 be arranged on support 201, the recovery flask 203 being connected to reflux condensing tube 202 lower end, surge flask 204, the distilling flask 205 that material to be concentrated is housed, motor 206; Described reflux condensing tube 202 is connected with distilling flask 205 by surge flask 204, and distilling flask 205 upper end is connected with the axle that is rotatably connected, and the axle that is rotatably connected drives distilling flask 205 to rotate by motor 206, and distilling flask 205 is placed in water bath 207; Reflux condensing tube 202 is communicated with vavuum pump 10.Several roller 208 is provided with bottom described support 201.
