Description
Technical field
The use of the new type is related to a kind of medical supplies, especially a kind of fetal head position measuring appliance.
Background technique
Currently used fetal cephalometry mode is to be touched by the hand of doctor or doctor is directly visited into private parts with finger and carried out
Simple measurement, such the first inaccuracy of measurement method, second, which carrys out painful for pregnant woman, will increase, for psychologically may
People is allowed to can not accept a little.
Utility model content
The utility model mainly for problem above, provide it is a kind of can in such a way that vaginal dilator is combined with detector
The position of detection fetal head safely and fast, the addition of vaginal dilator reduce pain of pregnant woman during producing inspection, the addition of detector
Make measurement more accurate, its technical solution is as follows:
A kind of fetal head position measuring appliance includes: vaginal dilator and measuring appliance two parts, and de- tear open of measuring appliance is connected on vaginal dilator,
There is card slot on vaginal dilator, measuring appliance is installed on the card slot of vaginal dilator, and measuring appliance is made of handle and measuring rod, and measuring rod is by pushing away
Bar and feeler lever composition, push rod one end are fixedly connected with feeler lever, and the other end of push rod is connect with handle, and handle pushes push rod forward,
Push rod drives feeler lever mobile, is carved with length scales on feeler lever, vaginal dilator by maxilla, lower jaw, stick up bar, fixed link and adjusting rod group
At, lower jaw is fixedly connected in fixed link, and maxilla is rotationally connected on adjusting rod, the lower end of adjusting rod mobile connection and lower jaw,
Adjusting rod is bolted position, stick up bar adjust maxilla the angle that raises up, fixed link by the position card column of nut stick up bar consolidate
Surely the position of bar is stuck up.
On that basis of the above technical scheme, the handle of the measuring appliance is hinge-connection structure, is pushed away by engaging handle
Bar, handle and sticks up and has skid resistance strip on bar.
On that basis of the above technical scheme, the vaginal dilator and detector are all made of nonmetallic disposable material, handle
On return spring is installed.
The utility model beneficial effect is: being capable of detection safely and fast in such a way that vaginal dilator is combined with detector
The position of fetal head, the addition of vaginal dilator reduce pain of pregnant woman during producing inspection, and the addition of detector makes measurement more quasi-
Really.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the partial structural diagram of the utility model；
Specific embodiment
The utility model is described in further detail with example with reference to the accompanying drawing:
As depicted in figs. 1 and 2, a kind of fetal head position measuring appliance includes: 4 two parts of vaginal dilator 1 and measuring appliance, measuring appliance 4
De- tear open is connected on vaginal dilator 1, has card slot on vaginal dilator 1, measuring appliance 4 is installed on the card slot of vaginal dilator 1, and measuring appliance 4 is by handle
Hand 10 and measuring rod composition, measuring rod is made of push rod 8 and feeler lever 9, and 8 one end of push rod is fixedly connected with feeler lever 9, push rod 8 it is another
One end is connect with handle 10, and handle 10 pushes push rod forward, and push rod 8 drives feeler lever 9 mobile, is carved with length scales on feeler lever 9, is expanded
External genitals 1 by maxilla 2, lower jaw 3, stick up bar 5, fixed link 6 and adjusting rod 7 and form, lower jaw 2 is fixedly connected in fixed link 6, maxilla 3
It is rotationally connected on adjusting rod 7, the lower end of adjusting rod 7 mobile connection and lower jaw 3, adjusting rod 7 is bolted position, sticks up bar
5 adjust the angle that raises up of maxilla 2, and fixed link 6 sticks up the fixed position for sticking up bar 5 of bar 5 by the position card column of nut, we will first
Vaginal dilator is placed in the degree that private parts adjusts folding, then visits into private parts measuring appliance along the card slot of vaginal dilator, then nibbles
It closes handle feeler lever to lean out, removes measuring appliance after encountering fetal head, see the scale on feeler lever, obtain accurate numerical value.
Preferably, the handle 10 of the measuring appliance 1 be hinge-connection structure, by engagement handle push push rod, handle 10 with
Sticking up on bar 5 has skid resistance strip.
Preferably, the vaginal dilator 1 and detector 4 are all made of nonmetallic disposable material, are equipped with back on handle 10
Position spring.
The utility model in such a way that vaginal dilator is combined with detector can safely and fast detection fetal head position,
The addition of vaginal dilator reduces pain of pregnant woman during producing inspection, and the addition of detector makes measurement more accurate.
The utility model is illustrated by way of example above, but the utility model is not limited to above-mentioned specific implementation
Example, all ranges that the requires of the utility model protection is belonged to based on any changes or modifications that the utility model is done.
