Description

Gynaecology and obstetrics uses pelvis measuring apparatu

Technical Field

The utility model relates to the technical field of medical equipment, in particular to gynaecology and obstetrics uses pelvis measuring apparatu.

Background

The pelvis is the most important component of the birth canal and is usually measured at the time of prenatal examination. The pelvis measuring instrument used at present is mostly composed of a swing arm, an articulated shaft and an arc graduated scale. Moreover, the existing pelvis measuring instrument has single function and narrow application range, and can only be used for measuring the inner diameter or the outer diameter of the pelvis. The same pelvic measurement instrument does not allow measurement of both the internal and external pelvic diameters.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a gynaecology and obstetrics uses pelvis measuring apparatu that can measure pelvis internal diameter, also can measure the pelvis external diameter.

In order to solve the technical problem, the utility model discloses a scheme does: the utility model provides a gynaecology and obstetrics uses pelvis measuring apparatu, includes body and fixed connection arc scale on the body, be close to on the body the one end of arc scale articulates there is the handle, keeps away from the one end threaded connection of arc scale has a measuring cylinder, the handle is close to the one end an organic whole of arc scale is provided with first measuring arm, be close to on the body the fixed second measuring arm that is provided with of one end of arc scale.

Preferably, the measuring cylinder comprises a measuring cylinder body, a first handle is fixedly arranged at one end of the measuring cylinder body, a second handle is fixedly connected to the other end of the measuring cylinder body through a telescopic rod, and the telescopic rod penetrates through the measuring cylinder body.

Preferably, one end of the measuring cylinder body, which is close to the telescopic rod, is provided with a screw used for controlling the telescopic rod to stretch.

Preferably, the arc-shaped graduated scale is provided with a first graduation line.

Preferably, the telescopic rod is provided with second scale marks.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a set up the arc scale on the body, measure the arm through arc scale and first measurement and second and cooperate and measure the pelvis internal diameter, utilize and measure the pelvis external diameter, specifically utilize and place the arc scale in measurand's pelvis inboard, the handle rotates, thereby measure the pelvis internal diameter through the scale mark that reads on the arc scale, and simultaneously, when needing to measure the pelvis internal diameter, a measurer one hand is holding the first in command and is put in one side of measurand outer pelvis, then another hand is holding the second in command, measure measurand's pelvis external diameter through twitching the telescopic link, it can to read the numerical value on the second scale mark.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1-3, the utility model discloses a gynaecology and obstetrics uses pelvis measuring apparatu, including body 1 and fixed connection arc scale 2 on the body 1, the one end that is close to arc scale 2 on the body 1 articulates there is handle 3, keeps away from the one end threaded connection of arc scale 2 has a measuring cylinder 4, handle 3 is close to the integrative first measuring arm 5 that is provided with of one end of arc scale 2, the fixed second measuring arm 6 that is provided with of one end that is close to arc scale 2 on the body 1.

In order to measure the external diameter of the pelvis conveniently, the measuring cylinder 4 comprises a measuring cylinder body 41, one end of the measuring cylinder body 41 is fixedly provided with a first handle 42, the other end of the measuring cylinder body 41 is fixedly connected with a second handle 44 through an expansion rod 43, and the expansion rod 43 penetrates through the measuring cylinder body 41.

In order to facilitate the control of the telescopic rod 43, a screw 45 for controlling the telescopic rod 43 to extend and retract is disposed at one end of the measuring cylinder 41 close to the telescopic rod 43.

In order to facilitate the measurement of the inner diameter of the pelvis, a first scale mark 21 is arranged on the arc scale 2.

In order to facilitate the measurement of the external diameter of the pelvis, the extension rod 43 is provided with a second scale mark 431.

Specifically, the utility model discloses a set up the arc scale on the body, measure the arm through arc scale and first measurement and second and cooperate and measure the pelvis internal diameter, utilize and measure the pelvis external diameter, specifically utilize and place the arc scale in measurand person's pelvis inboard, the handle rotates, thereby measure the pelvis internal diameter through the scale mark that reads on the arc scale, and simultaneously, when needing to measure the pelvis internal diameter, a measurer one hand is holding the first in command and is put one side at measurand person's outer pelvis, then another hand is holding the second in command, measure measurand person's pelvis external diameter through twitching the telescopic link, it can to read the numerical value on the second scale mark.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
