Abstract
The utility model belongs to a gynaecology's palace chamber inspection instrument, it has been solved in remote area, the problem of no commercial power supply area difficult exploration contraceptive ring and making amniotic fluid inspection and palace chamber inspection, it comprises probe, mirror body, eyepiece frame, objective, eyepiece, rod mirror and lighting system, the rod mirror dress is in the probe, and threaded connection is used with mirror body to probe and eyepiece frame, and the eyepiece dress is in the eyepiece frame, and light source optical axis and primary optical axis contained angle are not more than 48, and the formation of image magnification is 2.5 ~ 3.5. The utility model is suitable for the field contraception ring detection, amniotic fluid detection and uterine bottom disease examination in remote areas, and can be used with or without commercial power.
Description
This utility model belongs to the medical inspection instrument, and exactly it belongs to a kind of gynecological uterine cavity inspection apparatus.
At present, medical matters circle visit that ring is main to use instruments such as X-ray machine, B ultrasonic, but do not accomplish to make on-the-spot detection the in the women family educating, and a kind of portable X-ray machine is arranged, and can arrive on-the-spot the detection, but price are expensive, and volume is also bigger, uses inconvenience.When the women does amniocentesis and uses amniotic fluid scope, need to insert 8.5 millimeters thick probes of anemia of pregnant woman's vagina diameter, bring very big inconvenience to the anemia of pregnant woman, and amniotic fluid scope introduces illumination light by a semipermeable membrane, energy loss is big, and brightness of illumination is not high enough.Simultaneously, above-mentioned instrument and now clinical employed hysteroscope all must in the environment of commercial power supply is arranged, use, up to the present, find the instrument of lesion examining at the bottom of the family planning detection that can in the environment of no commercial power supply, use and the palace as yet.
The purpose of this utility model, be to provide a kind of modern design, structure advanced person, observe clear, make easy, easy to use, have a certain enlargement ratio, the gynecologial examination instrument that can in the environment of no commercial power supply, use.Be particularly suitable for that the scene, remote mountain areas does that intrauterine contraceptive loop is surveyed, amniotic fluid detects and the palace at the bottom of the Endoscope for uterine cavity of lesion examining.
This utility model is to realize like this, it is made up of probe, shank, eyepiece frame, object lens, eyepiece, excellent mirror and illuminator, it is characterized in that, the rod mirror is contained in the probe, object lens are contained in the shank, the probe with shank with being threaded, eyepiece is contained in the eyepiece frame, with being threaded, it is 2.5～3.5 that the angle of the primary optical axis that the light source optical axis of illuminator and excellent mirror, object lens and eyepiece are formed is not more than 48 ° of imaging amplifications between eyepiece frame and the shank.Illuminator is pen type torch that uses common miniature bulb or the optical fibers that the biography light characteristic is arranged.Objective focal length is for just, and eyepiece focal length is for negative.Probe length is not in 160 millimeters.
The utility model has the advantages that easy to manufacturely, easy to use, certain enlargement ratio arranged, have or not civil power all can use, be particularly suitable for scene from far-off regions and make intrauterine contraceptive loop and survey, amniotic fluid detect and the palace at the bottom of sick the inspection.For guarantee family planning work carry out smoothly and ensure the women healthy certain practical significance arranged.Below in conjunction with drawings and Examples this utility model is done further detailed description.
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model optical system scheme of installation.
1 is probe among the figure, and 2 is shank, and 3 is eyepiece frame, and 4 is illuminator, and 5 is excellent mirror, and 6 is object lens, and 7 is eyepiece, and 8 is light source.The rod mirror is to be formed by optical glass polish, be contained in that to form probe (1) shank (2) and eyepiece frame (3) in the steel pipe of being made by rustless steel injection molded through injection machine on mould for engineering plastics, object lens (6) are contained in the shank (2), eyepiece (7) is contained in the eyepiece frame (3), illuminator can adopt two kinds of forms, a kind of is the pen type torch that throws light on common miniature bulb, another kind is to adopt the optical fibers that can pass light, it is identical that the two installs the aperture, can exchange, when electricity is arranged, can use fiber-optic illuminated, not throw light on the aneroid battery torch when having electricity.After getting all the above-mentioned parts ready, seeing figures.1.and.2 to install gets final product.During use, probe segment inserts vagina, the spacing of rotation eyepiece frame pancratic lens and eyepiece, promptly regulate diopter, the user that can make different visions directly uses this instrument under the not corrigent state of vision, the focal power of eyepiece is a negative value, thereby what observe is erect image, not only easy to use, and has simplified structure.When commercial power supply was arranged, importing fibre-optic illumination light into was cold light, and this is because the condenser lens of light source has adopted filter infrared light material, thereby has filtered the infrared light that produces heat effect, has avoided the misery of bringing to the patient.The probe external diameter is 6.5 millimeters of Φ, and fortune is less than the probe external diameter of other analogous instrument, and length has guaranteed different patients are suitable for less than 160 millimeters.Manufacture and it should be noted that in the process that amplification is 3.15; The angle of the optical axis of being made up of light source optical axis and excellent mirror, object lens, eyepiece is 30 °, so that the angle of incidence of illumination light when reaching excellent Jing Bi and go up by excellent mirror end is greater than 42 °, the cirtical angle of total reflection of making the optical glass of excellent mirror is 42 °, thereby total reflection on excellent Jing Bi, all be mapped on the look-out station, avoid the luminous energy loss, improved the brightness of observing picture.Just, just can use common No. 5 batteries,, just can carry out adequate illumination with the light that bulb sent of general torch because the total reflection principle of light is incorporated into illumination light.Like this, be the family planning of its layer of China, prenatal and postnatal care and gynecological's medical work provide a kind of novelty, advanced, light suitable gynecological's Medical Instruments.
