By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art can be understood other advantages of the present utility model and effect easily by the content disclosed by this specification.
Refer to Fig. 1 to Fig. 3.Notice, structure depicted in this specification institute accompanying drawings, ratio, size etc., the most only in order to coordinate the content disclosed in description, understand for those skilled in the art and read, it is not limited to the enforceable qualifications of this utility model, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size, under not affecting effect that this utility model can be generated by and the purpose that can reach, all should still fall in the range of the technology contents disclosed in this utility model obtains and can contain.Simultaneously, in this specification cited as " on ", D score, "left", "right", the term of " middle " and " " etc., it is merely convenient to understanding of narration, and it is not used to limit the enforceable scope of this utility model, being altered or modified of its relativeness, changing under technology contents without essence, when being also considered as the enforceable category of this utility model.
Noncontacting proximity sensor joint as Figure 1-3, including basal disc 1 and open sensor probe chamber resettling 2, described basal disc 1 is provided with transparent partition 11, described sensor probe chamber resettling 2 is connected with described basal disc 1 and is positioned at the side of described transparent partition 11, and the opposite side of transparent partition 11 is provided with conversion film.
The sensor probe chamber resettling of described opening refers to that described chamber is provided with opening, and described opening can be used for facilitating sensor probe to insert.
Described conversion film and described sensor probe chamber resettling 2 are respectively arranged on the both sides of described transparent partition 11.Arrow shown in Fig. 2 points to the side being provided with conversion film.During use, described conversion film contacts with testing liquid, and sensor probe is fixed in sensor probe chamber resettling, with conversion film relative and with testing liquid through transparent cut off isolate.
Described basal disc can be installed container with liquid to be measured and engage.As a example by cell culture bags, can be by the one side of described basal disc 1 or edge and described cell culture bags phase welding or weld, the position of the corresponding transparent partition 11 of cell culture bags is provided with opening, this opening makes the conversion film on transparent partition can contact with culture fluid in cell culture bags, and the sensor probe inserting sensor probe chamber resettling 2 is then isolated with culture fluid in cell culture bags due to the existence of transparent partition 11.
It is also preferred that the left described transparent partition 11 water white transparency, both sides are smooth.Smooth transparent partition is more conducive to conversion film color and passes through.
Described transparent partition 11 is not limited to only be located at the middle part of described basal disc 1, and the basal disc only needing transparent partition periphery to leave one fixed width be enough to combine with cell culture bags.
Described sensor probe chamber resettling 2 can be with sensor probe grafting or threaded.
In a preferred embodiment, described sensor probe chamber resettling 2 is provided with female thread 21.Coupling, described sensor probe is provided with external screw thread.The threaded stability that may further ensure that sensor probe detects.
Described film of changing causes color-changing membrane or dissolved oxygen cause color-changing membrane into pH.
PH causes color-changing membrane and refers to convert printing opacity color according to the pH value of contact liq.PH causes color-changing membrane and can be obtained by masking after pH indicator and filmogen mixture.PH causes pH cause color-changing membrane described in color-changing membrane and belongs to prior art, the pH sensing membrane etc. used such as pH electrode.
Change the sensor connector that film is pH cause color-changing membrane to match with RGB sensor and white light source.The mechanism of its detection pH value is: pH causes the color-changing membrane pH value turn colors according to its contact liq, thus affect white light source and penetrate the color of this film, white light source coordinates pH to cause color-changing membrane can be changed into color signal by pH signal, the detection of RGB sensor penetrates conversion film and the color signal of transparent partition, relation according to conversion film color with pH value knows that liquid to be measured installs the pH value of liquid to be measured in container, and conversion film color can utilize the standard solution detection of known pH value to obtain with the relation of pH value in advance.
Dissolved oxygen causes color-changing membrane can convert printing opacity color according to the dissolved oxygen value of contact liq.Dissolved oxygen causes color-changing membrane and can be obtained by masking after dissolved oxygen indicator and filmogen mixture.Dissolved oxygen causes dissolved oxygen cause color-changing membrane described in color-changing membrane and belongs to prior art.
Change the sensor connector that film is dissolved oxygen cause color-changing membrane to match with RGB color sensor and white light source.The mechanism of its detection oxygen dissolving value is: dissolved oxygen causes the color-changing membrane dissolved oxygen concentration turn colors according to its contact liq, thus affect white light source and penetrate the color of this film, white light source coordinates dissolved oxygen to cause color-changing membrane can be changed into color signal by dissolved oxygen signal, the detection of RGB color sensor penetrates conversion film and the color signal of transparent partition, relation according to color Yu dissolved oxygen concentration knows that liquid to be measured installs the dissolved oxygen value of liquid to be measured in container, and the relation between conversion film color and dissolved oxygen can utilize the standard solution detection of known dissolved oxygen concentration to obtain in advance.
In order to preferably protect conversion film, the outer of the side that described transparent partition 11 is provided with conversion film is provided with the bead 3 protruding from basal disc 1.Described bead can alleviate culture fluid for conversion film impact to further ensure that the stability that sensor probe detects.
Described sensor probe chamber resettling 2 can fix with basal disc 1 that to be connected also can be detachable connection.Detachable connected mode includes but not limited to grafting, threaded etc..
It is also preferred that the left described sensor probe chamber resettling 2 and basal disc 1 junction rounding off.
Noncontacting proximity sensor joint of the present utility model is particularly suited for cell culture bags.
Through noncontacting proximity sensor joint of the present utility model, in liquid to be measured installation container, pH and the dissolved oxygen situation of liquid to be measured can be converted into color signal, by accessing RGB sensor probe in sensor probe chamber resettling, color signal can be converted to level signal or square-wave signal, the controller of RGB sensor reads level signal or square-wave signal, the level signal corresponding according to conversion film color and pH value and the transformational relation of dissolved oxygen, it is thus achieved that the pH value of cell culture fluid and oxygen dissolving value.Level signal and the transformational relation of pH value and dissolved oxygen that conversion film color is corresponding such as can be drawn curve acquisition beforehand through after the standard solution detection to known pH value or oxygen dissolving value by routine techniques.
In sum, this utility model effectively overcomes various shortcoming of the prior art and has high industrial utilization.
Above-described embodiment only illustrative principle of the present utility model and effect thereof, not for limiting this utility model.Above-described embodiment all can be modified under spirit and the scope of the present utility model or change by any person skilled in the art.Therefore, art has all equivalence modification or changes that usually intellectual is completed under without departing from the spirit disclosed in this utility model and technological thought such as, must be contained by claim of the present utility model.
