Abstract
The utility model relates to a kind of double sacculus cervical dilatation conduits of novel communication type, including tube body and forward and backward sacculus, the tube body is that the head end of single lumen catheter is equipped with top guide, and the top guide and tube body head end are tightly connected；The tube body is equipped with former and later two water injection holes in the position at top guide rear；There are two the sacculus, respectively preceding sacculus and rear sacculus, and forward and backward sacculus is tightly connected with tube body, and forward and backward water injection hole is located in forward and backward sacculus and is connected to corresponding sacculus；Tube body rear end is equipped with connector, and two balloon interiors pass through tube body intercommunication.Double two balloon interiors of sacculus communicate, principle is transmitted according to liquid pressure, the pressure constantly shunk in uterine cavity can be passed through to forecourt bag pressure and be transferred to sacculus after cervical department by force, expansionary force is allowed to gradually increase, it can be with the effect of natural adaptation uterine cavity and Cervix and then adjustment press expansion cervix, mitigate patient suffering, improves clinical efficiency.
Description
Technical field
The utility model relates to the field of medical instrument technology more particularly to a kind of single-chamber connection mechanically expanded for uterine neck
The double sacculus cervical dilatation conduits of general formula.
Background technique
Clinically, it is the obstetrics' remedy measures for having much challenge, mesh that the patient bad to uterine neck condition, which implements induced labor,
Before, it is known that induced laboring method there are mainly two types of: one is pharmaceutical methods, another kind is physical method.Pharmaceutical methods promote uterine neck
The implementation of mature measure may make final result more complicated, and some drugs treatment may not only generate side effect and lead to induced labor
Failure rate rises, and finally still may need to terminate gestation by caesarean birth.
Another kind is physical method, principle are as follows: cervix constantly stimulated using mechanical force, and then activates collagenolysis enzyme,
The collagenous fibres for destroying uterine neck keep uterus softening mature.But existing cervical dilatation conduit (lead by such as cook cervical dilatation
Pipe), design is located at uterine neck two sides using two sacculus, and double balloon pressures inside and outside cervix opening squeeze stimulation uterine neck,
Act on limited, smaller for the effect of entire uterine neck, limitation is larger, and clinical effectiveness is dissatisfied.
Summary of the invention
In view of the above-mentioned problems, the utility model provides a kind of double sacculus cervical dilatation catheter designs of single-chamber communication type, it can
With lasting expansion constantly stimulation cervix maturation, effectively shortens the delivery of baby time, it is just before giving birth painful to slow down patient.
Concrete scheme: a kind of double sacculus cervical dilatation conduits of novel single-chamber communication type, including tube body and forward and backward ball
Capsule, the tube body are that the head end of single lumen catheter is equipped with top guide, and the top guide and tube body head end are tightly connected, and can not also set top guide, directly
Tube body head end is wrapped up using preceding sacculus；The tube body is equipped with former and later two water injection holes in the position at top guide rear；The sacculus has
Two, respectively preceding sacculus and rear sacculus, forward and backward sacculus are tightly connected with tube body, and forward and backward water injection hole is located at forward and backward
It is connected in sacculus with corresponding sacculus；Tube body rear end is equipped with connector；Preceding sacculus, rear sacculus are respectively placed in uterine cavity and uterine neck when in use
Place, by tube body intercommunication, according to liquid pressure transfer principle, front and back sacculus pressure is consistent two balloon interiors, can be by palace
The intracavitary pressure constantly shunk is transferred to by force sacculus after cervical department by forecourt bag pressure, is allowed to expansionary force and gradually increases.Preceding sacculus
It can provide persistently after volume requirement water filling to providing certain pressure in uterine cavity, it is proposed that maximum volume is not less than 250mL；To avoid pair
Fetus causes extruded length to be no more than 6 centimetres.Length of balloon covers cervical length range afterwards, may be designed as 3~6 centimetres, is
Meeting persistently to apply expansionary force to cervix, and maximum extension diameter is not less than 8 centimetres.
The beneficial effects of the utility model are: the utility model provides a kind of double sacculus cervixs expansions of novel single-chamber communication type
Conduit is opened, which communicates, and transmits principle, the pressure that will can constantly shrink in uterine cavity according to liquid pressure
It is transferred to sacculus after cervical department by force by forecourt bag pressure, is allowed to expansionary force and gradually increases, it can be with natural adaptation uterine cavity and uterine neck shape
State and then the effect for adjusting press expansion cervix mitigate patient suffering, improve clinical efficiency.
Detailed description of the invention
Fig. 1 is to have the double sacculus cervical dilatation conduit schematic cross-sectional views of top guide communication type
Fig. 2 is the double sacculus cervical dilatation conduit schematic cross-sectional views of no top guide communication type
Fig. 3 is the double sacculus cervical dilatation conduit use state diagrams of communication type
Specific embodiment
The utility model is described below in conjunction with the drawings and the specific embodiments.As shown in Figure 1, the tube body 1
For elongate single lumen catheter, the head end of the tube body 1 is equipped with top guide 3, and the top guide 3 and 1 head end of tube body are tightly connected；The tube body 1
Position below top guide 3 is equipped with preceding water injection hole 6 and rear water injection hole 7；There are two the sacculus, respectively preceding capsule 2 and rear capsule 3,
Preceding capsule 2 and rear capsule 3 and tube body are tightly connected, and preceding water injection hole 6 is located in preceding capsule 2 to be connected to preceding capsule 2, and rear water injection hole 7 is located at rear capsule 3
It is interior to be connected to rear capsule 3；1 tail end of tube body is equipped with connector 4, by connector 4 to 2 injecting normal saline of sacculus.
As shown in figure 3, the double sacculus cervical dilatation conduits of the utility model single-chamber communication type are when in use, tube body 1 is inserted
Enter into uterine cavity, it is ensured that preceding capsule 2, rear capsule 3 completely into uterine cavity and uterine neck, then inject about 100ml physiology to connector 5 respectively
Salt water transmits the principle of pressure according to liquid equipressure, when the pressure enhanced in uterine cavity is transferred to cervical department sacculus, is allowed to pressure increasing
By force, with natural adaptation uterine cavity and Cervix and then pressure can be adjusted, mitigates patient suffering, improves clinical efficiency.
The utility model is not limited to above embodiment, initiative spirit according to the present utility model, art technology
Personnel can also make other variations, these variations done according to the spirit and principles of the utility model, should all be included in this
Within the scope of utility model protection.
