DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to the extemporaneous analysis of a body fluid or liquid, which is present in an intracorporeal cavity, by means of a portable, and if appropriate disposable, device. By way of a non-limiting example of the scope of the present invention, the latter relates to the extemporaneous analysis of the cervical mucus which is present in the uterine neck of the vagina of the female body.
The subject of the present invention is a portable, and if appropriate disposable, device which is particularly simple as regards its use and which safeguards the intracorporeal cavity, and especially its mucous membrane, from any contact with analysis reagents.
DESCRIPTION OF THE PRIOR ART
According to the document DE-U-85 31432, a portable device has been proposed and described uniquely for taking samples of intrauterine mucus, and intrauterine fluid, and this by way of the uterine neck.
This device comprises: temporarily in the intrauterine cavity; tube, including a gripping end which emerges from one side of said tube, and at the other end an elastic ring capable of assuming two positions, namely an open position in the intrauterine cavity, and a closed or clamped position inside the tube; this elastic ring is itself made up of four continuous branches, symmetrical in pairs with respect to the axis of the tube, namely, in the open position, two branches widening out from the distal end of the tube, and two branches forming an obtuse angle joining them; two symmetrical branches of the sampling means are thus capable of being spaced apart angularly with respect to one another; the tube, namely a retracted position, in which the branches of the sampling means are drawn together in pairs, and in which the abovementioned ring is closed or clamped, and a deployed position in which the branches spread apart in pairs, outside the tube, at its distal end, in order to obtain the open position of the abovementioned ring.
Such a device cannot also be used for a particular analysis or measurement of the biological specimen and/or body fluid sampled, since in particular the sample taken has to be transferred to and analyzed in a laboratory, for example for anatomical and pathological examination.
Moreover, such a device is brought in its deployed position, with the sampling ring completely open, into the intrauterine cavity itself. This results in a medical maneuver which is aggressive, and even traumatizing for the patient.
The subject of the present invention is a device for taking a sample of, more particularly, a body fluid, and not a biological cell specimen (as for a biopsy), and permitting, with the same means, a direct, extemporaneous analysis or measurement of the body fluid sampled, and this without aggression vis-a-vis the patient.
In accordance with the present invention, the sampling means comprises two branches, each one including a free end provided with an element for sampling of the body fluid. These sampling elements are drawn together and protruding at the distal end of the tube, in the retracted position of the rod. They are spaced apart from one another outside the tube, in the deployed position of this same rod. Thus, the sampling device is also adapted for extemporaneous measurement of the spinnbarkeit of the body fluid sampled, between the two sampling elements, in the deployed and spaced-apart position of the two branches, outside the intracorporeal cavity. these two branches are arranged in relation or with respect to the tube in such a way that, in the retracted position of the rod, the sampling elements of the two branches are drawn together and remain at the distal end of the tube, and in a deployed position these same sampling elements are spaced apart outside the tube, at its distal end.
The functioning of such a device is as follows: device is introduced into the intracorporeal cavity until contact is made between the distal end of the tube and the wall of said cavity, for example the mucous membrane of the cervix; protruding from said end, the latt
