Abstract
The invention belongs to a kind of medical apparatus, comprise measuring device and controller, measuring device constitutes with dark measuring staff by surveying handle, and controller adopts computerized control system.Can measure the transverse diameter and the vertical footpath of uterine cavity, and demonstrate measurement data automatically, also can demonstrate the type and the model of preferred intrauterine device (IUD), improve the success rate of IUD technology, can be widely used in teaching, clinical and scientific research service.
Description
The invention belongs to a kind of medical apparatus, particularly a kind of computer measuring equipment that is used to measure women's cavity of uterus form and data.
At present, worldwide, intrauterine device (use hereinafter to be referred as the IUD technology very extensive, particularly populous, be that China of fundamental state policy is more popular with the family planning, existing so far 60,000,000 women have adopted IUD.Yet for many years, no matter be to produce the model of IUD or implement the IUD technology, in the department of obstetrics and gynecology technical literature, lack the science partial data that the uterus uterine cavity shape is provided.Its basic reason is not measure the modern equipment of uterine cavity.Existing measurement apparatus mostly is a probe-type, can only measure the vertical footpath of uterine cavity simply, and the transverse diameter data are inferred by experience, make the side effect that has occurred in implementing the IUD technology human body, secondary damage and complication.
The purpose of this invention is to provide the computer control survey instrument that a kind of energy measurement also shows uterine cavity shape and data simultaneously, improve the success rate of IUD technology, promote the remodeling of IUD to regenerate.
The present invention is designed to: measuring instrument comprises controller and measuring device, and measuring device constitutes by surveying handle and feeler.Feeler comprises vertical footpath measuring staff, Antennaria dioica (L.) Gaertn (Gnaphalium dioica L..) formula transverse diameter measuring staff and measures sleeve pipe.Survey handle and contain two measurement reset coils, can offset with vertical directly two contacts of measuring staff, transverse diameter measuring staff respectively, and be provided with the measurement slide block and measure push button.The afterbody of surveying handle is connected with controller by cable.Controller has adopted computerized control system, and it comprises the control data input circuit, D/A converting circuit, and the one-chip computer integrated circuit, delivery outlet, choosing ring graphics display circuit shows the uterine cavity data circuit.The design rational in infrastructure of measuring device and the automatic control of computer system, make device measures of the present invention and show the vertical footpath of uterine cavity, the transverse diameter data, and energy automatic selection of optimal T-shape " O " type and 14 kinds of IUD models of uterine cavity type, select " IUD " type of required employing and the model of all kinds of " IUD " exactly.

Measuring instrument of the present invention comprises measuring device and controller.The structure of measuring device can be referring to Fig. 1 to Fig. 3.It constitutes by surveying handle (5) and feeler (1).Feeler feeds to be surveyed in the handle, and it comprises measures sleeve pipe (2), Antennaria dioica (L.) Gaertn (Gnaphalium dioica L..) formula transverse diameter measuring staff (3) and vertical footpath measuring staff (4).The transverse diameter measuring staff touches with measurement reset coil (6) by the measurement slide block (8) in the handle mutually along the contact of handle orientations.Vertical footpath measuring staff touches with measurement reset coil (7) mutually along the contact of handle orientations.Measure slide block and be provided with and measure push button (9), it can carry out level with slide block and moves forward and backward, and drives Antennaria dioica (L.) Gaertn (Gnaphalium dioica L..) formula transverse diameter measuring staff and move.When measuring the vertical footpath of uterine cavity, Antennaria dioica (L.) Gaertn (Gnaphalium dioica L..) formula transverse diameter measuring staff is positioned at surveys pipe-in-pipe.When measuring the uterine cavity transverse diameter, but hand push is measured push button, two Antennaria dioica (L.) Gaertn (Gnaphalium dioica L..) formula contacts (22,23) of transverse diameter measuring staff is stretched out along the through hole (10) of measuring the sleeve pipe both sides, and be expanded to the transverse diameter of surveying.Telescopic taking measurement of an angle can be 25 °～45 °, and the handle afterbody of measuring device is connected to cable socket and links to each other with controller.
The control circuit system of controller can be referring to Fig. 4 to Fig. 6, and computerized control system comprises Data Control input circuit (11); It mainly comprises two potentiometer (17), and monostable trigger (18), and monostable trigger adopts the 74LS221 chip; D/A converting circuit (12); Adopt analog-digital chip (ADC0809), one-chip computer integrated circuit (13); It comprises CPU(24) and EPROM memory (25), delivery outlet (14); Adopt three eight distortion delivery outlets (8255 chip), show uterine cavity data circuit (16); It (74LS47) is made up of with six seven segment numerical display tubes (20) six decoding driving chips (19), choosing ring graphics display circuit (15); It drives 6 plane display tubes (22) by six audions (21) and forms.The surface structure of controller can be referring to Fig. 7, and wherein, (26) are digital display screen, and (27) are pattern displaying, and (28) are louvre, and (29) for connecting the measuring device socket, (30) are power panel.
The operation principle of instrument of the present invention and measuring process are;
Measure the transverse diameter and the vertical footpath data of uterine cavity with measuring device, measurement reset coil by the different numbers of turn converts length to voltage signal in its ratio again, voltage signal is delivered to the digital to analog converter passway by the potentiometer of the control data input circuit in the controller, send the startup switching signal by control circuit to digital to analog converter, after converting, send out to computer integrate circuit and to convert signal, after CPU receives and converts signal, data are got in the memory, and shown all data by display.
At first, measure the vertical footpath of uterine cavity, move handle, earlier feeler is sent into tested intrauterine, after at the bottom of measuring staff touches the palace, the contact (31) that puts in place, vertical footpath puts in place, sends the vertical footpath signal that puts in place to computer, to indulge the footpath data after computer is received immediately and be stored in the reservoir, and on charactron, show by digital display circuit.Measure the uterine cavity transverse diameter again, promote to measure push button, after Antennaria dioica (L.) Gaertn (Gnaphalium dioica L..) formula measuring staff contacts Uterus wall, the transverse diameter contact (32) that puts in place puts in place, sends the signal that puts in place to main frame, after main frame is received, immediately the transverse diameter data are deposited in the reservoir, show on charactron by digital display circuit, with 1 centimeter second transverse diameter of measuring uterine cavity of handle post-tensioning, identical again with the method for measuring first transverse diameter.When three groups of data of size of the vertical footpath of uterine cavity and first transverse diameter measuring show on the controller after, controller is selected the type of IUD of required usefulness and the model of all kinds of IUD exactly according to the data that collected.
Adopt instrument of the present invention, can not only improve the success rate of IUD technology, reduce mortality, and can obtain uterine cavity shape data and new data, can be widely used in teaching, clinical and scientific research service.
