Description

Cervical dilatation measuring device and cervical dilatation measuring glove

Technical Field

The utility model relates to an obstetrical department's guardianship field, in particular to cervical dilatation measuring device, cervical dilatation measuring gloves.

Background

Cervical dilatation is accompanied by a childbirth process, requiring immediate attention. Cervical dilatation is of great importance in the criteria of labour. Such as: in the new product standard, cervical dilatation of 6cm is taken as a marker of active phase, and the diagnostic standard of active phase arrest is as follows: when the membrane is broken and the cervix uteri expands more than or equal to 6cm, if the uterine contraction is normal, the active period stagnation can be diagnosed when the cervix uteri stops expanding for more than or equal to 4 hours; if the uterine contraction is not good enough, the active period can be diagnosed by stopping the cervical dilatation for more than or equal to 6 hours. Arrest of active phase can be used as an indication for caesarean section. Accurate and quantitative measurement of cervical dilatation therefore helps the doctor to make an accurate judgment of the progress of labor.

Currently, in clinical examination of cervical dilatation, the cervical dilatation is estimated by fingers. During measurement, the index finger and the middle finger are stretched into the vagina to the cervical orifice, and then the index finger and the middle finger are stretched to estimate the cervical dilatation. Due to invisibility, the cervical dilation estimated with the fingers is very error, especially for inexperienced physicians, the measurement error is much larger. Many scholars have therefore begun to use instruments to accurately measure cervical dilation.

For how to measure cervical dilatation, US6270458 describes a computer aided labor monitoring system based on ultrasound ranging technology, measuring cervical dilatation and fetal head position parameters during the labor process. US6200279 describes an apparatus for monitoring the progress of labor by monitoring a position sensor to achieve a position of a birth delivery portion of a fetus relative to the mother's pelvis during the course of labor. US patent 6669653 describes a device for monitoring the progress of labor by attaching a key or shaped object to one or more points on the mother or fetus to provide a reference or fixed point for a position sensor to monitor the position of the cervix. Chinese patent CN200710027843.0 (publication No. 100558299C, publication date 11/2009) describes an automatic cervical dilatation and fetal head position measuring method based on an ultrasonic triangulation method, and proposes a monitoring system. Chinese utility model patent publication No. CN102415905B, electronic partograph system based on magnetic field tracking and positioning technology, discloses a cervical dilatation measuring method, which uses a magnetic field positioning sensor to track the positions of cervical orifices on both sides and monitors cervical dilatation in real time.

The basic principle of the cervical dilation measuring device is that a positioning device is adopted to track the dilation distance of the cervical orifice, but actually, due to the biological properties of the cervix, the dilated cervical orifice may be in a closed state during measurement, and the actual cervical dilation can be accurately measured only by slightly pushing the cervical orifice open. Meanwhile, in the vaginal digital examination, a doctor can also check the softness, the maturity, the position of the cervical canal and the like of the cervix. Therefore, the above cervical dilation measuring device is not clinically applicable.

Thus, applicants believe that, to date, fingers remain the most desirable vaginal test tool. The cervical dilation measuring device of the application can improve the accuracy of vaginal finger examination on the basis of vaginal finger examination.

Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.

Examples

The present embodiment provides a cervical dilation measuring apparatus, comprising:

as shown in fig. 1, a cervical dilation measuring apparatus, comprising: a flexible rope measuring unit 101, a catheter 102 and a marker body 103; a flexible rope S is arranged in the flexible rope measuring unit 101 and used for measuring the length of the flexible rope S pulled out, and the flexible rope S penetrates through the guide pipe 102 and is connected with the marking body 103;

during measurement, the marking body 103 and the catheter rope outlet end 1021 are used for marking two sides of a cervical orifice respectively, and the length of the flexible rope between the rope outlet end 1010 of the flexible rope measuring unit and the catheter rope outlet end 1021 is kept unchanged. 1

Cervical dilatation is accompanied by a childbirth process, requiring immediate attention. Cervical dilatation is of great importance in labor standards, and accurate and quantitative measurement of cervical dilatation helps doctors to accurately judge labor progress. Currently, in clinical examination of cervical dilatation, the cervical dilatation is estimated by fingers. During measurement, the index finger and the middle finger are stretched into the vagina to the cervical orifice, and then the index finger and the middle finger are stretched to estimate the cervical dilatation. However, since it is not visible, the cervical dilatation error estimated with the fingers is large, and the measurement error is larger for inexperienced doctors. Recently, many scholars have started to accurately measure cervical dilatation by using a distance measuring device, and the basic principle is to use a positioning device to track the dilatation distance of the cervical orifice. Meanwhile, in the vaginal digital examination, a doctor can also check the softness, the maturity, the position of the cervical canal and the like of the cervix. Therefore, the above cervical dilation measuring device is not clinically applicable. The applicant believes that, to date, fingers remain the most ideal cervical dilation detection tool.

To accurately measure the distance between two fingers entering the cervix, this embodiment uses the length of the flexible cord to mark the measured cervical dilatation. The principle of marking the cervical dilatation by the length of the flexible cord is that the marking body 103 is fixed on one finger, the catheter cord outlet end 1021 is fixed on the other finger, and the flexible cord S passes through the catheter 102 from the marking body 103 and then is connected with the flexible cord measuring unit 101. When measuring the cervical dilatation, firstly, the two fingers are closed, at the moment, the length of the pulled flexible rope recorded by the flexible rope measuring unit 101 is L1, then the two fingers go deep into the vagina to reach the cervical orifice, the degree of the stretched fingers is compared with the cervical orifice expansion degree, namely, the cervical dilatation is realized, at the moment, the length of the pulled flexible rope recorded by the flexible rope measuring unit 101 is L2, the distance between the two fingers is the distance between the two fingers, and then the width of the two fingers is supplemented, namely, the cervical dilatation value is realized. The technical scheme of the flexible rope measuring unit 101 for measuring the pulled-out length of the flexible rope can refer to a pull rope displacement sensor, a pull rope electronic ruler and the like in the prior art. A flexible rope belt type electronic ruler and a measuring method thereof (application number: 201810806378.9) disclosed in the Chinese utility model patent published as 2018, 10 and 19 is also disclosed, and the structure and the action principle of the flexible rope electronic ruler are also clearly described in the flexible rope belt type electronic ruler.

Due to the particularity of the female cervical anatomy (represented by the dashed cervical os and vaginal walls in fig. 1), this patent introduces a catheter 102, through which the flexible cord S is connected to the marker body 103; during measurement, the marking body 103 and the catheter rope outlet end 1021 are used for marking two sides of a cervical orifice respectively, and the length of the flexible rope between the rope outlet end 1010 of the flexible rope measuring unit and the catheter rope outlet end 1021 is kept unchanged. The reason for this is: (1) the flexible rope S is sent into the vagina by using the catheter 102, the marking body 103 and the rope outlet end 1021 of the catheter mark the two sides of the cervical orifice respectively, and the cervical dilatation is represented by the distance between the marking body 103 and the rope outlet end 1021; (2) in the measuring process, the length of the flexible rope between the rope outlet end 1010 of the flexible rope measuring unit and the rope outlet end 1021 of the guide pipe is kept unchanged, so that the distance change measured by the flexible rope measuring unit can accurately represent the distance change between the marker 103 and the rope outlet end 1021 of the guide pipe.

It should be emphasized that, in order to ensure the accuracy of cervical dilatation measurement, the length of the flexible string between the outlet end 1010 of the flexible string measuring unit and the outlet end 1021 of the catheter is kept constant during measurement, that is, the length of the flexible string S in the catheter 102 is kept constant during test, and the distance between the inlet end 1020 of the catheter and the outlet end 1010 of the flexible string measuring unit is kept constant during test.

Thus, at the time of measurement, first, the flexible cord S in the catheter 102 should be kept taut and should not wrinkle, and it does not matter whether the catheter 102 is a rigid catheter or a bendable flexible catheter. Secondly, the flexible rope between the conduit rope inlet end 1020 and the flexible rope measuring unit rope outlet end 1010 should be kept in a tight state, and in the specific implementation, the conduit rope inlet end 1020 and the flexible rope measuring unit rope outlet end 1010 may be directly butted, or a section of flexible rope is exposed as shown in fig. 1, which is all the purpose, but it is necessary to ensure that the exposed flexible rope is not wrinkled during the measuring process. That is, the material selection of the conduit 102 and the embodiment of the conduit 102 connected to the flexible line measuring unit 101 are as long as the functional requirements are met: the flexible rope length between the flexible rope measuring unit rope outlet end 1010 and the catheter rope outlet end 1021 remains unchanged and is equal to the technical idea of the utility model, which should be contained in the protection scope.

Preferably, the flexible string measuring unit 101 is placed outside the body during measurement, and the flexible string S is inserted into the vagina along the catheter 102.

In this embodiment, since the space in the vagina is small, the marker 103 and the catheter outlet 1021 are used for marking the two sides of the cervical orifice, and the marker 103 and the catheter 102 only have a marking function, so that the marker can be designed to be small in implementation and is not easy to be perceived by a parturient during testing. While the flexible cord measuring unit 101 is bulky, the present embodiment places the flexible cord measuring unit 101 outside the body, and the flexible cord S extends into the vagina along the catheter 102.

As a preferred embodiment, in order to measure the cervical dilatation more conveniently, the cervical dilatation measuring device further comprises a first sleeve body 201 and a second sleeve body 202, the marking body 103 is arranged on the first sleeve body 201, and the catheter outlet end 1021 is arranged on the second sleeve body 202; the first sleeve 201 and the second sleeve 202 can be worn on a first finger and a second finger respectively.

Referring to fig. 2, the marking body 103 is disposed on the first sheath body 201, and the catheter outlet end 1021 is disposed on the second sheath body 202; the first sleeve 201 and the second sleeve 202 can be worn on a first finger and a second finger respectively. Thus, the operator can accurately measure the expansion distance of the cervical orifice by using the traditional vaginal digital examination method. It should be further noted that the shape of the catheter 102 can be customized according to the actual situation, as long as the length of the flexible rope in the catheter 102 is kept constant during use. It is also to be reminded that the width of the supplementary two fingers is also taken into account when calculating the end result of cervical dilatation.

It should be noted that, the first sleeve body and the second sleeve body can be implemented in various ways, such as a "jacket" type shown in fig. 2 or a "finger sleeve" type shown in fig. 3 (the first sleeve body 301 and the second sleeve body 302 shown in fig. 3), and the purpose of the implementation is to fix the marker body 103 and the catheter rope outlet end 1021 to two fingers respectively, then mark the two sides of the cervical orifice with the marker body 103 and the catheter rope outlet end 1021, represent the distance between the two fingers with the distance between the marker body 103 and the catheter rope outlet end 1021, and then calculate the width of the two fingers as the cervical dilatation value.

It is conceivable that the marker, the first sleeve body, the catheter outlet end, the second sleeve body, the catheter inlet end, etc. are named only from the functional point of view, and some parts may be designed and integrated together in the specific implementation, for example: in specific implementation, the marker 103 is disposed on the first sheath 201, and the catheter exit end 1021 is disposed on the second sheath 202, and the marker 103 and the first sheath 201, and the catheter exit end 1021 and the second sheath 202 are designed and integrated together. These embodiments are equivalent to the technical idea of the present invention, and all should be included in the protection scope of the present invention.
