Description
Technical field
This utility model relates to blood cell collection equipment technical field, particularly a kind of adsorption-type pressure transducer for pocket type blood cell separator.
Background technology
At present, the blood cell separator of single use pocket type is a kind ofly transferred with TRIMA blood cell separator is matching used the single use consumptive material realizing blood component and be separated by centrifugal cylinder high-speed rotary, when carrying out blood cell collection, the pressure change of channel interior quite greatly, for the serviceability preventing channel interior pressure limit from affecting product, one or more pressure transducer can be set usually on-line measurement is carried out to the pressure of crucial pipeline, feed back to seperator simultaneously and then pump and pipeline switch are regulated, play adjustment loine pressure, ensure the effect of normal acquisition, but, existing pressure transducer usually there will be stress reaction situation not in time, the deleterious consequence causing some difficulty or ease to be expected occurs.
Summary of the invention
For solving the problem, this utility model provides a kind of adsorption-type pressure transducer for pocket type blood cell separator, comprises housing, lid, silicone rubber membrane, brace, fixed groove, inlet, liquid outlet; Housing is connected with the lid of annular, and the joint face place of described housing and lid forms fixed groove; There is brace at silicone rubber membrane center, and described silicone rubber membrane edge is fixed in fixed groove, and brace and shell inner surface surround cavity, surround docking port with lid; Housing both sides are respectively arranged with inlet, liquid outlet, and the oral area of described inlet, liquid outlet is just to cavity.
Further, described housing is circular, and lid is annular.
Further, described silicone rubber membrane is circular.
Further, described brace is circular.
The beneficial effects of the utility model are:
This utility model detects the pressure of pipe-line system by the mode of magnetic absorption, thus sets up the pressure monitor system of a fast and stable, and structure is simple, is easy to produce, reliable and stable.

Detailed description of the invention
As shown in Figure 1, this utility model comprises housing 1, lid 2, silicone rubber membrane 3, brace 4, fixed groove 5, inlet 6, liquid outlet 7.
Housing 1 and lid 2 are respectively in-mould decoration part, and housing 1 and lid 2 ultrasonic bonding are integrated, and described housing 1 sidewall and lid 2 joint face place form fixed groove 5.The shape of housing 1, lid 2 can be chosen according to practical situation.The present embodiment selects housing 1 to be circular, and lid 2 is annular.Silicone rubber membrane 3 is circular, and center has a circular irony brace 4(concrete shape to choose according to the actual requirements).Described silicone rubber membrane 3 edge is fixed in fixed groove 5, and brace 4 and housing 1 inner surface surround cavity 8, surround docking port 9 with lid.
Housing 11 both sides are respectively arranged with inlet 7, liquid outlet 8.The oral area of described inlet 7, liquid outlet 8 is just to cavity 8.
Using method of the present utility model is:
As shown in Figure 2, pocket type blood cell separator consumptive material is arranged on device panel, adopt the mode of magnetic absorption by brace 4 holding steadily by the joint pin 10 on device panel during operation, thus the pressure in accurate detection cavity 8, be transferred to other control elements of equipment by pressure transmitter 11, and then play the effect regulating loine pressure in time.
The beneficial effects of the utility model are:
This utility model detects the pressure of pipe-line system by the mode of magnetic absorption, thus sets up the pressure monitor system of a fast and stable, and structure is simple, is easy to produce, reliable and stable.
