Description

The device of real-time continuous monitoring ruminant tumor gastric juice pH value

Technical field

This utility model relates to a kind of monitoring device, specifically, but relates to the monitoring device that the ruminant tumor gastric juice pH value is monitored on a kind of real-time continuous ground.

Background technology

Learn in the research at ruminant animal nutrition,, often need to monitor the dynamic change of ruminant its rumen fluid pH value in a day or a couple of days in order to study needs.

Usually, the experimenter gathers the liquid sample in the ruminant tumor gastric at regular intervals one time, then, measures its pH value apace at animal body external acidometer, record data are drawn out the dynamic changing process of ruminant tumor gastric juice pH value in a day or several days at last.The drawback of this monitoring method is: monitoring frequency is limited, can't react the continuous situation of change of (in one day or several days) ruminant tumor gastric juice pH value in the special time all sidedly.

Report is also arranged, and the someone utilizes the acidometer monitoring ruminant tumor gastric juice pH value that has time recording and printing function to change.He is that the corrosion resistant acidometer that will have higher holding capacity is placed in the cud of ruminant, measure, write down the rumen fluid pH value of ruminant in real time, the experimenter draws the dynamic changing curve of ruminant tumor gastric juice pH value according to the data of acidometer record.The drawback of this monitoring method is: 1, the acidometer of Cai Yonging involves great expense, because the pH value electrode of this acidometer need have higher holding capacity and corrosion resistance, avoid the pH value electrode to be caused damage by the food chyme in the cud.Particularly when the bull experimental animal was monitored simultaneously, equipment had high input.2, in observation process, owing to there is not the protective measure of electrode signal transmission line, it is movable that experimental animal need be fixed in the very little scope, influences the health of experimental animal.

Summary of the invention

In order to overcome the shortcoming of the device that existing monitoring ruminant tumor gastric juice pH value changes, but the purpose of this utility model provides a kind of monitoring device of simple in structure, real-time continuous ground monitoring ruminant tumor gastric juice pH value that cost is low.This monitoring device not only can be realized the monitoring of the real-time continuous of ruminant tumor gastric juice pH value and record, and the animal of monitored test can be free within the specific limits movable, the health of guarantee test animal.

For achieving the above object, this utility model by the following technical solutions: a kind of real-time continuous is monitored the device of ruminant tumor gastric juice pH value, and it is made of pH electrode, pH electrode line protector, pH conveyer and monitor; PH electrode is inserted in the cud of ruminant, and it spills the outer pH electrode line of animal body after the protector protection, links to each other with the signal input part of pH conveyer, and the signal output part of pH conveyer links to each other with the signal input part of monitor.

The electrode body outside of described pH electrode is with an electrode protection cover, and this electrode protection cover is worked out by finer wire, is covered with one 50 order nylon wires again in the outside of finer wire, and attached with 100 grammes per square metre things;

Be with the stable pipe of electrode that a usefulness medium-soft plastic tube is made in the electrode wires outside of described pH electrode, between stable pipe of electrode and electrode wires, be filled with implant.

Described pH electrode line protector is a bourdon tube, and this bourdon tube is the import PA bourdon tube of diameter 10mm, wall thickness 0.8mm, behind high-temperature shaping, is wrapped in the outside of pH electrode line.

The utility model has the advantages that: can have under the prerequisite of certain activity space the guarantee test animal; monitor in real time continuously and record ruminant tumor gastric juice pH value; overcome that to place the equipment investment of pH value determination of electrode method in the discontinuity of the external test of cud sampling in the past and the traditional cud big, the shortcoming that experimental animal can't normal activity.

The specific embodiment

As shown in Figure 1, but the device of the disclosed real-time continuous of this utility model monitoring ruminant tumor gastric juice pH value mainly constitute by pH electrode 1, pH electrode line protector 2, pH conveyer 3 and monitor 4; PH electrode 1 is inserted in the cud of ruminant, and it spills the outer pH electrode line of animal body after protector 2 protections, links to each other with the signal input part of pH conveyer 3, and the signal output part of pH conveyer 3 links to each other with the signal input part of monitor 4.Its operation principle is: pH electrode 1 is inserted in the cud of ruminant, by the pH value in the pH electrode real-time continuous ground measurement ruminant tumor gastric, and its measurement result is transferred to pH conveyer 3 by the pH electrode line, pH conveyer 3 is converted into the signal of pH electrode 1 output the standard signal of 4～20mA and is transferred to monitor 4, monitor 4 is converted into the signal of 4～20mA corresponding with it 1～14 pH value again, and be stored in the monitor, printing, the copies data that testing crew can be regular is used for analyzing.

In order not limit the range of activity of laboratory animal, simultaneously, guarantee that again the pH electrode line can be transferred to measuring-signal pH conveyer 3 safely, reliably, this utility model has been set up 2 pairs of pH electrode lines of a protector and has been protected in the outside of pH electrode line.In specific embodiment of the utility model, it is 10mm that this utility model adopts diameter, and wall thickness is the import PA bourdon tube of 0.8mm, behind high-temperature shaping, is wrapped in the outside of pH electrode line.Because treated bourdon tube has certain elasticity and hardness, so, the pH electrode line is had protective effect, the pH electrode line that is enclosed with this bourdon tube simultaneously can move along with monitored ruminant.

Fig. 2 is this utility model specific embodiment structural representation.In this embodiment, this utility model is selected 450CD type pH electrode that U.S. Sensorex company produces, that the ball electrode bubble can bear 100psi pressure for use.In order to make it can in cud, remain the ball electrode bubble downwards, be immersed in the rumen fluid, and electrode wires is not twined in cud always, this utility model has carried out processing as shown in Figure 3 to pH electrode.As shown in Figure 3, this utility model is with electrode protection cover 12 in the outside of pH electrode body 11, and this electrode protection cover 12 is worked out by finer wire, is covered with one 50 order nylon wires again in the outside of finer wire, and attached with 100 grammes per square metre things.In addition, be with the stable pipe 14 of electrode that a usefulness medium-soft plastic tube is made in the outside of the pH electrode line 13 that links to each other with pH electrode body 11, between stable pipe 14 of electrode and electrode wires 13, be filled with implant 15.

As shown in the figure; after in the pH electrode 1 insertion ruminant tumor gastric of above-mentioned processing; it spills the outer pH electrode line of animal body is to link to each other with the signal input part of pH conveyer 3 after the PA bourdon tube is protected through protector 2, and the signal output part of pH conveyer 3 links to each other with the signal input part of monitor 4.In the present embodiment, the 691N pH conveyer that this example selects for use Shanghai Ren Shi Electronics Co., Ltd. to produce, the MultiF R4000 type multichannel recording instrument without paper of selecting for use the SUPCON company limited to produce, monitor can be the storage of 1～14 pH value with the standard signal scope of being converted into, storing frequencies be per 0.2～5 second once.Testing crew can regularly copy the data that are stored in the monitor and be used for analyzing.

The above is specific embodiments of the invention and the know-why used, and is any based on the equivalent transformation on the technical solution of the present invention basis, all belongs within the protection domain of the present invention.
