Description
The present invention is a kind of intelligent cervix dilator device that high-tech arts such as Modern Transducer Technology, computer technology, machinery, chemical industry are utilized elastic component that relates to.
In the prior art, cervix dilator is with various stainless steel rod stiffener, the stainless steel rod of different size is one group, from diameter Ф 3.5-10, this intra-uterine dilator, doctor's troublesome poeration need repeatedly insert and extract the stainless steel rod of different size, and doctor's anxiety, the patient suffering, easily abrade, bleed, infect.
The purpose of this invention is to provide that a kind of doctor is easy and simple to handle, the Intelligeut automatic womb dilator of patient's no pain.
The object of the present invention is achieved like this: Intelligeut automatic womb dilator includes intra-uterine dilator handle (13), probe (15), its special character is that it also includes liquid-way system, fluid injection gear box and Based Intelligent Control plate, described intra-uterine dilator handle (13) is nontoxic, transparent material is injection molded, its front end is connected with the rustless steel probe (15) that is injected into one with the intra-uterine dilator handle, the two hollow links to each other, the probe flexible mantle of (15) overcoat (14) also compresses mantle (14) end with pressure cap (20), described fluid injection gear box (2) is outside equipped with motor (1) and is located by connecting with it, be with runner (8) in the rotating shaft of motor, stud with metal derby (9) on the runner (8), metal derby (9) with match near electrical switch (10), link to each other with the Based Intelligent Control plate near electrical switch (10), motor (1) links to each other with worm screw (23) by its rotating shaft, worm gear (3) links to each other with screw mandrel (4), worm gear (3) and screw mandrel (4) all are connected on the fluid injection gear box (2), screw mandrel (4) links to each other with impregnator plug (22), be connected with liquid-way system between the inlet of the outlet of impregnator and intra-uterine dilator handle (13), be provided with three-way valve (11) and pressure transducer (12) in the middle of the liquid-way system, described Based Intelligent Control plate is 8031 single-chip microcomputers (17), bar-graph display (18) and selection hole enlargement switch (19) are formed, and link to each other liquid-way system with motor (1), the fluid injection gear box, the Based Intelligent Control plate is loaded in the shell (24).
Compared with prior art, inserting the intrauterine probe of patient uses elastic component to replace stiffener, order about mantle expansion automatically in the footpath, palace by Based Intelligent Control plate and fluid injection gear box with liquid-way system, reach till the preset diameters, therefore the doctor is easy to operate, light, and the patient reduces misery, has avoided scratch, bleeds and has infected, bulge test before family planning service is done miscarriage reaches satisfied Expected Results.
Be described in detail technical solution of the present invention below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a profile sketch map of the present invention.
As Fig. 1,2, Intelligeut automatic womb dilator includes intra-uterine dilator handle (13), probe (15), its special character is that it also includes liquid-way system, fluid injection gear box and Based Intelligent Control plate, described intra-uterine dilator handle (13) is nontoxic, transparent material is injection molded, its front end is connected with the rustless steel probe (15) that is injected into one with the intra-uterine dilator handle, the two hollow links to each other, the probe flexible mantle of (15) overcoat (14) also compresses mantle (14) end with pressure cap (20), described fluid injection gear box (2) is outside equipped with motor (1) and is located by connecting with it, be with runner (8) in the rotating shaft of motor, stud with metal derby (9) on the runner (8), metal derby (9) with match near electrical switch (10), link to each other with the Based Intelligent Control plate near electrical switch (10), motor (1) links to each other with worm screw (23) by its rotating shaft, worm gear (3) links to each other with screw mandrel (4), worm gear (3) and screw mandrel (4) all are connected on the fluid injection gear box (2), screw mandrel (4) links to each other with impregnator plug (22), be connected with liquid-way system between the inlet of the outlet of impregnator and intra-uterine dilator handle (13), be provided with three-way valve (11) and pressure transducer (12) in the middle of the liquid-way system, described Based Intelligent Control plate is 8031 single-chip microcomputers (17), bar-graph display (18) and selection hole enlargement switch (19) are formed, and link to each other liquid-way system with motor (1), the fluid injection gear box, the Based Intelligent Control plate is loaded in the shell (24).
Above-mentioned mantle can be to be squeezed to draw by the 20-35 root scribbled of Ф 0.2 and spandex to form, and the mantle external diameter is Ф 3.5, comprcssive strength≤0.2-0.4MPa, expansion outside dimension D≤10
Produce driving pulse by the Based Intelligent Control plate, motor (1) just changes, drive worm screw (23), worm gear (3) advance the screw mandrel (4) of impregnator (5) downwards, then normal saline or distilled water impel the mantle on the intra-uterine dilator probe (15) to expand through three-way valve (11), pressure transducer (12), intra-uterine dilator handle (13) in the impregnator, the thickness of its upset diameter D size, depend on that impregnator releases liquid capacity V and pressure P fully, have functional relation:
D＝f（V，P）
According to selecting hole enlargement switch (19) to preset retaining in advance, the dynamo series pulse voltage is given in 8031 single-chip microcomputers (17) computing in the Based Intelligent Control plate automatically, and fixed pulse amplitude, pulsewidth and definite pulse number, then the motor revolution just is determined, can reach predetermined diameter D, the display of hole enlargement is simultaneously acted on from motion tracking by 8031 single-chip microcomputers (17) and ICL7182 bar-graph display (18), display digit analog quantity bar figure.
By runner (8) and on the metal derby (9), the effect of electronic proximity switch (10) inlayed, motor whenever rotates a circle, electrical switch provides a step-by-step counting, this actual measurement total revolution of motor and Based Intelligent Control plate preset number and are compared automatically by 8031 single-chip microcomputers, at any time adjust the motor speed, finally reach the actual measurement revolution and conform to, just can reach the purpose of pre-expansion palace diameter with the control revolution.
Liquid-way system, three-way valve (11) and pressure transducer (12) are all made with insulant, and impregnator push rod (21) is that poly fourfluoroplastics is made, and human body is not had electric leakage extremely may.
Before the work intra-uterine dilator handle is connected, dial three-way valve (11) to initial bit, the liquid in the fluid infusion device (16) is by going out probe from baric flow, when seeing in the transparent liquid-way system no bubble, again three-way valve (11) is pushed working position, set up mantle (14) again, tighten pressure cap (20) and get final product work.
Good and sound intra-uterine dilator handle during use will select hole enlargement switch (19) to push initial bit, and the aerofluxus bubble makes system be full of liquid, by tight probe mantle, will pop one's head in and insert cervix uteri, will select hole enlargement switch (19) to press job key, dialling three-way valve is working position, treats that 30-60 expands the palace and finish second.
