Definitions

• the present invention concerns a pocket microscope device, with a limited run of the eye-piece and with the aimed observation of the sole prepared frame, for the determination of the woman's fertility, based on a specimen of dry saliva.
• microscopes are used, begining from those used in laboratories in the health care institutions, to the portable ones.
• a PC-2000 product consisting on an optic enlarge- ent means, a plane for the saliva, a sleeve of the microscope and an electric, constructive element, characterized in that:
• the optic enlargement element is connected with the container by means of a threading
• the lighting takes place by means of a bulb that irradiates white light, the lighting contact is performed by a mechanic switch and the feeding by means of a standard battery of the LR6N kind.
• said product shows the following inconveniences : relating to the container, the optic constructive element is demountable, and may therefore easily get dirty, which makes it difficult to find again the frame on the field of the object, as the run of said optic constructive element is not limited;
• the plane of the object is out of plastic material and demountable, so that the dust particles negatively affect the correct vision of the frame of the dry saliva;
• the lighting takes place by means of a yellow LED diode, and a mechanic switch is provided.
• the replacing of the battery is provided in such a manner that the electric constructive element must be pushed out of the microscope sleeve, which for the user is little practical.
• the aim set forth is reached by means of the device according to the present invention, comprising a microscope-optic portion with a limited sliding of the eye-piece and an aimed observation of the function surface of the object support, which has the advantage, with respect to other existing similar devices, that the field of vision consists only of the frame of the preparation (dry saliva), and that by means of the rotation of the enlargement unit only a further focusing of the frame - depending on possible dioptric defects in the users ' eyes - within +/- 5 dioptres (Dpt), occurs.
• the systems for the run limitation assure contemporarily that the microscope can not be disassembled; infact, in case of separation of these units, dust or other dirt might get onto the non functional surface, making the observation of the function surface difficult or even impossible, if much dirt enters; should this occur, the microscope would be practically unserviceable, as none of the users has knowledges or means for well cleaning the internal surface so as to make it again optically limpid and transparent; - the teaching of the user for the discovery and identification of the frame position is useless, as it is the detail of a little "depth of field", which is a feature of small as well as of big microscopes; thus, a great safety and easiness in use is achieved, which is an important feature of all instruments for individual use.
• the device according to the present invention is provided with a lighting unit which, for replacing the battery, may be taken off and re-inserted by a light rotation in the supporting envelope, and may be respectively close or open; said simple and demountable connection is obtained due to suitable projections in the lighting supporting body and corresponding grooves in the supporting envelope.
• Said constructive solution has the following advantages:
• a further feature of the device according to the present invention consists of the use of a micro- switch, for turning on and off the lighting, so as to obtain the following, further advantages:
• the pressure performed with the finger onto the micro-switch is the slightest, which allows the total concentration of the user; and concentration is fundamental for easily observing and identifying the structure of the dry saliva; an imperfect switch that works in an intermittent way and that during the observation modifies the lighting level, makes the use difficult and sometimes even impossible;
• the field of vision of the device according to the present invention is lighted with a green-yellow ray from a LED; this light colour is not harmful for the eyes and allows - much more than other colours - the identification of even the smallest detail of the saliva, which implies a correct diagnose of the fertility and avoids possible mistakes. In this way, a quick identification and the most flexible observation of the frame are achieved without any harm for the eyes , as it may occur especially with a prolonged use if, as a light source, a colour beam harmful for the eyes is used.
• Figure 1 shows a scheme of a non demountable microscope device with a limited run of the eyepiece and an aimed observation of the function surface of the object support, according to the present invention.
• Figures 2 and 3 show a variant of the microscope unit with an inclination cam.
• Figure 4 shows a variant of a microscope unit according to the present invention, with a stop system.
• Figure 5 shows the details of the lighting and electric feeding elements .
• Figure 6 shows a scheme of the inner structure of the container, according to figure 1.
• the enclosed figures show a pocket microscope device, with a limited run of the eye-piece and with the aimed observation of the sole prepared frame, for the determination of the woman's fertility, mainly consisting of a mini-microscope unit 1, of an electric unit 2 for lighting the dry saliva frame, of a support container 3 and of a coating envelope 4.
• the mini-microscope 1 is placed in the high part of the support container 3, and the six grooves 5, symmetrically performed in the container, allow a slow microscope insertion and extraction movement, preventing at the same time its rotation in the container during the focusing of the dry saliva frame; in the lower part of the container said electric unit 2 is placed which, by means of cams 6 and corresponding grooves 7, forms an easily demountable connection.
• the microscope according to the present invention consists of two small units: an enlarging unit 1, consisting of an optic portion 9 placed in the fitting 8, and a unit 10 consisting of an object support 11 and of its fitting 12.
• the optic portion and the object support are glued in their fittings.
• the optic part contains a plurality of lens.
• Units 1 and 10 are movable in opposition, and at the same time their connection is of the non demountable kind.
• the stop is asymmetric, i.e. eccentric, and is glued to fitting 12; the position of the cams and of the eccentric base are conceived for guiding the observation always onto the function surface 18 of the object support, onto which the structure of the dry saliva is laid, allowing at the same time a perfect focusing, which means a clear frame, in consideration of the fact that a great number of users has a dioptric defect in their eyes.
• the sliding positions are therefore determined by the end 19 of the cams.
• the rotation connection and the longitudinal displacement of unit 1 in fitting 22 are performed by means of the connection of threading 12, where the stop system 20, 21 is in a precisely definite relationship, which allows the sole observation of the function surface of the object support, sliding limitation as well as a perfect focusing, i.e. a clear frame in relation to the dioptric defects in the eyes of the user.
• the impossibility of disassembly of units 1, 10 is determined by the fix connection of the stop system 21 with the support of the optic portion 8 and of the stops 20, linked together to the fitting 12 of the object support.
• the lighting of the dry saliva frame takes place by means of the independent unit shown in figure 5, consisting of a body in which batteries 23, a spring 24, the insulation surface and the micro- contact units are arranged, and on the upper part whereof the LED 25, that irradiates the green- yellow light, and the resistance 26 are arranged.
• cams 6 are duly provided onto the body of said unit, and during the insertion of said unit into the support container 3 they are inserted into grooves 7, forming an easily demountable connection.
• the opening 27 provided on said body is for pushing the upper battery with the help, e.g., of the point of a ball-point pen, when the batteries are to be replaced, so that both batteries come out from opening 28; all parts, apart from the batteries, are firmly fixed to the body.
• the use of the device according to the present invention may be described as follows :
• the microscope unit 1 is taken out from the support container 3 ;
• the eye is neared to the eye-piece and the light is turned on by a pressure of the forefinger onto the micro-switch 29; without turning the eye-piece, the user will see in her own field of vision the frame of the dry saliva;
• the frame is perfectly focused in the way corresponding to the possible dioptric defect in the eyes of the user; according to the structure of the frame, the fertility or the non-fertility may be ascertained.
• the remaining saliva is removed from the syrface 18 and the microscope unit is placed again into the coating envelope 4.
