Description
Technical field
This utility model relates to a kind of obstetrics medical apparatus and instruments, specifically a kind of negative-pressure type cephalotracter.
Background technology
Cephalotracter is a kind of midwifery instrument that department of obstetrics and gynecology are conventional.When maternal uterine shrinks weak, prolonged second stage of labor,
Or puerpera suffers from some disease, should not be at second stage of labor Overexertion, or fetus is in the case of Following Hypoxia in Uterus etc. is multiple, and midwifery is cured
Life is many can use cephalotracter to carry out midwifery, helps delivery of baby.
The negative-pressure type cephalotracter used clinically is mainly by structures such as fetal head suction hood, breather and negative pressure generators
Becoming, fetal head suction hood matches with the head size of fetus, holds by negative pressure and draw fetal head.But, inhale owing to connecting fetal head
Cover mostly is hard body with the breather of negative pressure generator, is not easy to carry out fetal head suction hood insertion vagina the traction behaviour of uteri position
Make.And the intensity of the breather of software is not enough, it is easy to be pulled off in the traction process of fetal head, causes apparatus to damage and traction
Failure.So, existing negative-pressure type cephalotracter can only carry out the fetal head traction at vaginal orifice position, and can not carry out palace mouth and lead
Draw, use and there is significant limitation.
Utility model content
The purpose of this utility model is just to provide a kind of negative-pressure type cephalotracter, to solve the traction of existing negative-pressure type fetal head
The use limitation that device exists, meets clinical use needs.
This utility model is achieved in that a kind of negative-pressure type cephalotracter, including negative pressure pump and sucker, described negative
Be connected between press pump with described sucker and have flexible suction catheters and rope form connector, described rope form connector be arranged on described in bleed
Interiorly or exteriorly, and when described rope form connector is in tensioning state, described suction catheters is in non-tensioned shape to conduit
State.
Described negative pressure pump is pneumatic negative pressure pump or manual negative pressure pump.
Described manual negative pressure pump includes vacuum pump and manual wedge；It is plugged with negative pressure mark post in one end of described vacuum pump；
It is connected to guide pole and suction nozzle between described vacuum pump and described manual wedge.
Described sucker is the round mouth big tripe discoid body of end face opening, and dish mouth diameter is not more than 7cm, is provided with and inner chamber trying to get to the heart of a matter
The grafting hole slot communicated；The port of described suction catheters is fixedly connected on described grafting hole slot.
Being provided with pressure support thing in described sucker, described pressure support thing is the cushion body with breathability.
Silk, rope, chain or the spring that described rope form connector metal material is made, to form seal wire, guide chain or to lead spring.
Silk that described rope form connector plastic material is made or rope.
Silk that described rope form connector fibrous material is made or rope.
This utility model is by pneumatically or manually arranging flexible suction catheters and being flexible coupling between negative pressure pump and sucker
Seal wire, guide chain, form the negative-pressure type cephalotracter that a kind of sucker position can arbitrarily change, so, both can carry out at vaginal orifice
Fetal head traction, also sucker can be inserted uteri position, carry out palace mouth fetal head draw operations, thus expand fetal head traction be suitable for
Scope, shortens the stages of labor of puerpera, alleviates the misery of puerpera, meets the use needs of clinic.This utility model improves
Suction catheters and the pull intensity of be flexible coupling seal wire, guide chain, eliminate the conduit tensile phenomenon in fetal head traction process, it is to avoid make
Become apparatus to damage, improve the success rate of draw operations.

Detailed description of the invention
As it is shown in figure 1, this utility model includes negative pressure pump and two major parts of sucker.Described negative pressure pump can be pneumatic
Negative pressure pump, it is also possible to be manual negative pressure pump.It is connected between negative pressure pump with sucker 1 and has flexible suction catheters 3 and rope form connector
4, rope form connector 4 cross-under is in the inside of suction catheters 3, and its one end connects with negative pressure pump, and the other end connects with sucker 1, and
When rope form connector 4 is in tensioning state, suction catheters 3 is in unstrained state.I.e. pulling of sucker is by rope form even
Fitting 4 rather than pull suction catheters 3 to realize, is the most just avoided that and is broken by suction catheters 3.
Negative pressure pump in the present embodiment is manual negative pressure pump.In Fig. 1, manual negative pressure pump includes the vacuum pump 6 of cylinder,
One end of vacuum pump 6 is plugged with negative pressure mark post 5, is connected to two and guides pole 7 and three suction nozzles 9 on the sidewall of vacuum pump 6,
Manual wedge 8 is socketed in guiding pole 7 and the outer end of suction nozzle 9.
Sucker 1 is the round mouth big tripe discoid body of end face opening, and dish mouth diameter is not more than 7cm, in order to be built in uteri position.
Tray bottom at sucker 1 is provided with the horizontal grafting hole slot communicated with sucker inner chamber, and the grafting port of suction catheters 3 stretches into spliced eye
In groove, and be fixed on by the way of ultrasonic bonding on the hole wall of grafting hole slot, with the gas in smoothly suction sucker, with
Negative-pressure sucking is produced during sucker suction fetal head.In the dish of sucker 1, it is provided with pressure support thing 2(also can be not provided with pressure support
Thing), pressure support thing 2 is the cushion body with breathability, can be specifically metal class, Plastic, sponge kind, fiber-like, wadding
Shape things etc., suck too much by fetal head tissue during to avoid adsorbing, it is to avoid damage fetus head.
Silk, rope, chain or the spring that rope form connector 4 can be made with metal material；Can also be with plastic material or fibre
Tie up silk or rope that material is made, to form the seal wire or guide chain being flexible coupling.
Manually-operated negative pressure pump, presses manual wedge 8, makes manual wedge 8 move back and forth along guiding pole 7, passes through air-breathing
Gas in pipe 9 extracting vacuum pump 6, can make to produce in vacuum pump negative pressure.The negative pressure mark post 5 of vacuum pump 6 end is at evacuation
During progressively bounce back, according to retraction length and the body of rod on nominal scale value, the negative-pressure vacuum in vacuum pump can be grasped
Degree, to avoid because the excessive head to trailed fetus of suction force causes damage.After reaching the negative pressure value set, by leading
Draw manual negative pressure pump, under the induced effect of rope form connector 4 and sucker 1, can be by the fetus tractive in intrauterine or vagina
Out, thus assist puerpera to smoothly complete birth process.
