Abstract

The utility model relates to an optical microscope, particularly a portable micro tester which is used for detecting saliva to judge an ovulation period. The utility model provides a micro tester for the ovulation period so as to obtain the goals of the popularity of family types and the free measurement of the ovulation period of a person, wherein the micro tester for the ovulation period is formed by that a cassette mechanism is movably arranged in a housing with a micro lens, wherein the head part of the cassette mechanism is provided with a power supply; the tail part of the cassette mechanism is fixed with a switch of the power supply; the middle part of the cassette mechanism is fixed with a battery; a glass piece is vertically arranged on a light path between the micro lens and a light source. The test has the advantages of simplicity, compactness, low price, accurate detection, but no need of commercial power of 220 volts.

Description

A kind of micro measurement instrument of the carrying onset of ovulation

This utility model relates to a kind of optical microscope, particularly relates to a kind of portable micro-tester that body fluid is judged the onset of ovulation that is used to detect.

The method of general human body onset of ovulation has a variety of, for example: the body temperature of test person: or detect the urine of discharging every day with urine test paper, perhaps doing biochemical investigation to hospital and determine, is not very accurately and reliably but these methods have, have plenty of must go to chemically examine to hospital very inconvenient.Hospital does this class chemical examination and observes judgement with microscope at present, and this microscope is made up of camera lens, reflecting mirror, the support of band pedestal, micro-adjusting mechanism, light source, and its volume is bigger, causes and carries inconvenience; And 220 volts of civil powers of instrument use, use is restricted; Next is that the instrument price is not that everybody is consumable.

The purpose of this utility model is to overcome the deficiency of prior art, in order to popularize family type, the portable purpose that can measure people's the onset of ovulation whenever and wherever possible, thereby provide a kind of housing front end to fix a microlens, the terminal fixing movement of forming by light source, battery, switch, and on the light path between microlens and the light source, settle portable onset of ovulation of the micro measurement instrument of a microscope slide composition.

Task of the present utility model is achieved in that

Adopt materials such as plastics, metal to make tubular shell and movement, movement is contained in the housing, the housing front panel is microlens fixedly, the movement front end is installed light source, the centre is written into battery, afterbody is provided with the end that on and off switch is placed in housing, places a microscope slide between microlens 3 and light source 4, and microscope slide can take three kinds of modes to lay, 1. be housing 1 perpendicular to opening a groove on the optical path direction, flute length and widely can just insert microscope slide 7.2. be to be nested with a transition spool piece 12 screw threads outside microlens 3, the end of transition spool piece 12 is sealed by a microscope slide 7,3. is the front port embedding front cover piece microscope slide 7 of housing 1, microlens 3 is fixed on the front panel of upper shell cover 11.

The matched microscope slide useable glass of this utility model, transparent plastic material are made the slide that size matches with groove on the housing, body fluid that will be to be observed during use, be coated on the microscope slide as saliva, and make its natural drying (about 2～3 minutes), the light source direction that faces that microscope slide is scribbled saliva places, when opening light source switch, regulate microlens and make the clearly imaging of saliva figure, just can assess: a very important person is just locating just to have in the body fluid onset of ovulation typical fernlike crystal to occur, and it is a kind of helper of self-monitoring.

This utility model is that optical microscopy is combined with body fluid assessment, whether judges a kind of instrument of the onset of ovulation, simple small and exquisite the carrying of this apparatus structure by the appearance of measuring fernlike crystal in the body fluid; Only make power supply with the 1.5V battery, extremely easy to use; Low price is measured rapidly accurately, and it can be used as a kind of novel natural family planning method and promotes the use of.Below in conjunction with drawings and Examples this utility model is elaborated:

Embodiment 1:

This detector comprises housing (1), movement (2), microlens (3), light source (4), on and off switch (5), battery (6), microscope slide (7), upper shell cover (11), transition spool piece (12), and wherein microlens shell (8), magnifier (9), screening glass (10) are as one.Housing (1), movement (2), camera lens (3) structure are seen Fig. 1,2,3, be growth 80mm with plastics, wide 30mm, the uncovered square casing of an end (1) of high 20mm has a screw socket in the middle of its front panel, and the screw thread on the microlens shell (8) matches fixing with it, housing (1) top panel 1/4 place has a groove perpendicular to light path, can insert microscope slide (3), housing (1) inner bottom plating has two grooves, matches with the guide rail activity of casing (2) base plate; Casing (2) is made drawer-like with plastics, and front end is 1.5V bulb light source (4) fixedly, and tail end is fixed an on and off switch (5), middle packed battery (6); Wherein microlens (3) is made cylinder mirror head outer shell (8) by plastics again; the outside is threaded; it can match by the screw socket of screw thread and housing (1); imbed an enlarging lens of making of glass (9) in the mirror head outer shell (8); the screening glass (10) that the sticking again lastblock glass of its skin is done; the focal length of magnifier can be 4mm～20mm, can be that simple lens also can be a compound lens.Present embodiment is selected biconvex singlet lens for use, and the radius of curvature of two convex surfaces is 6mm, diameter 4mm.This detector by microlens (3) be screwed into or back-out change camera lens to saliva sample relatively to the position, to obtain picture rich in detail.Also can have 2～6 grooves in the housing inboard in order to store standby microscope slide.Embodiment 2

Manufacture by Fig. 5 structure, do housing 1 with the plastic cylinder of diameter of phi 20mm * long 55mm, fix a bulb on the cylinder front end face with Φ 17 * long 15mm or light emitting diode is done light source 4, fixed power source switch 5 on the terminal surface, the centre is put into battery 6 and is made the end port insertion housing internal fixation of movement 2 from housing 1, make hollow bolt shape framework with plastics, at hollow hole embedding lastblock simple lens (13), its focal length is the microlens 3 that 10mm does; The screw thread in the transition spool piece 12 and the external screw thread of microlens 3 match, its one is screwed in microlens 3 outsides, focus on by being screwed into to back-out to regulate, port seals a microscope slide 7 in addition, when their insert in housing 1 microscope slide 7 perpendicular to light path on, the diameter of transition spool piece 12 just less than housing 1 internal diameter a bit, just in time matches during insertion, has perhaps done groove or screw thread between them and has matched and all can.Upper shell cover 11 usefulness plastics are made the front end that is enclosed within housing 1.Embodiment 3
