Description
Technical field
This utility model relates to a kind of cervical cempetence testing fixture, specifically a kind of cervical cempetence dynamometry traction tube.
Background technology
Incompetence,cervical is also known as internal cervical orifice inadequacy, cervical orifice laxity.The cervix uteri fibre-bearing tissue of cervical incompetence patient, elastic fiber and smooth muscle etc. are all less, or due to the fracture of cervix uteri internal orifice fibrous tissue, isthmus sphincter ability reduces, and make cervix uteri be pathological dilatation and lax.The performance of cervical incompetence cervical incompetence mainly premature labor and in, late period Recurrent spontaneous abortion, habitual abortion person's incidence rate is 8% ~ 15%.
Cause the reason of incompetence,cervical a lot: one is congenital cervical incompetence: the incompetence,cervical patient of about 1/3 is caused by congenital factors, normal with gyneduct abnormal development, as unicornuate uterus or uterus septus, also may be histological changes of uterine cervix defect, cervix uteri elastin be containing quantity not sufficient.Two is posteriority cervical incompetences: roughly have several as follows: 1, parturition injury.When childbirth, operation are produced, cervix dilating causes cervical orifice to damage, as precipitate labor, macrosomia, orifice of uterus do not open full row breech extraction, obstetric forceps delivery etc.2, during artificial abortion, cervix dilating is too fast too quickly.In recent years due to Artificial Abortion and in the increase of pregnant induced labor, the incidence rate of traumatic cervical incompetence constantly rises.3, after also can being secondary to the anatomical structure change of cervix uteri or lower uterine segment, as there is muscular tumor.4, physiological cervical incompetence: cervix uteri internal orifice plays functional sphincter effect in trimester of pregnancy to have scholar to think, its cervix uteri internal orifice sphincter declines of the patient of subclinical uterine contraction or hypotonicity cervix uteri internal orifice.In addition, bromelain and papain can make relaxation of cervix.
Cervical incompetence, can not bear along with gestation month increases increasing of internal pressure of uterine cavity power, often mid trimester of pregnancy, amniotic membrane occurs and miscarries from breaking, and can discharge completely normal embryonal tissue.
At present, clinically for suspecting the patient having incompetence,cervical, Foley conduit distraction test is a kind of diagnostic method commonly used clinically.Foley conduit distraction test method is as follows: Foley conduit is put into uterine cavity, conductive pipe intracapsular injection enters 1ml water, make its diameter reach 6mm, if the in utero suspicious incompetence,cervical of mouth (pull strength is less than 600mg) i.e. easily can be pulled out, should make a definite diagnosis further.
But it is very inconvenient that pulling force surveyed by this Foley conduit, during use, or with feeling to provide a fuzzy pull strength, or stamping a knot in end, ergometer being hung over tying of accomplishing fluently and carrying out measurement pull strength.In addition, the afterbody due to Foley conduit has water injection end and tractive end, and the existence of water injection end adds the deadweight of tractive end, after especially the sacculus of Foley conduit is entered in water injection end water filling.
Summary of the invention
In order to overcome above-mentioned technical problem, the utility model proposes a kind of cervical cempetence dynamometry traction tube, comprise by conduit, catheter head is provided with water filling sacculus, water filling sacculus is connected with water-filling nozzle through waterflood path, described conduit comprises pipe and an outer tube in one, the cavity formed between inner and outer tubes is waterflood path, described water filling sacculus is positioned at the end of outer tube, water-filling nozzle is positioned at the end of outer tube, inner and outer tubes are connected as a single entity at end winding support, inner and outer tubes are at middle part, afterbody is connected by dowel, water-injecting cavity is provided with between the afterbody of interior pipe and outer tube afterbody, the dowel of pipe afterbody and water-filling nozzle in connecting is provided with in water-injecting cavity, described water-filling nozzle is provided with stretch ring.Described water-filling nozzle is circular or square orifice.Stretch ring can be one, also can be two, if two stretch rings, is then oppositely arranged on respectively on the dual-side of water-filling nozzle.
Beneficial effect: first, because water-filling nozzle and conduit are structure as a whole, relative to Foley conduit, saves special water filling port, alleviates the deadweight of Foley tail end of conduit, improve the degree of accuracy of dynamometry.Secondly, water-filling nozzle is provided with stretch ring, can be connected with dynameter very easily, improve the convenience of Foley conduit distraction test.

Detailed description of the invention
Embodiment: as Figure 1-4, a kind of cervical cempetence dynamometry traction tube, comprise by conduit 1, conduit 1 head is provided with water filling sacculus 2, water filling sacculus 2 is connected with water-filling nozzle 4 through waterflood path 3, described conduit 1 comprises an interior pipe 5 and an outer tube 6, the cavity formed between interior pipe 5 and outer tube 6 is waterflood path 3, described water filling sacculus 2 is positioned at the end of outer tube 6, water-filling nozzle 4 is positioned at the end of outer tube 6, interior pipe 5 and outer tube 6 are connected as a single entity at end winding support, interior pipe 5 and outer tube 6 are at middle part, afterbody is connected by dowel 7, water-injecting cavity 8 is provided with between the afterbody of interior pipe 5 and outer tube 6 afterbody, the dowel 7 of pipe 5 afterbody and water-filling nozzle 4 in connecting is provided with in water-injecting cavity 8, described water-filling nozzle 4 is provided with stretch ring 9.Described water-filling nozzle 4 is circular or square orifice.Stretch ring 9 can be one, also can be two, if two stretch rings, is then oppositely arranged on respectively on the dual-side of water-filling nozzle 4.
During Clinical practice, the first step, puts into uterine cavity by this utility model cervical cempetence dynamometry traction tube; Second step, injects 1ml water by water-filling nozzle 4 to water filling sacculus 2, water from water-filling nozzle 4, through water-injecting cavity 8, flow through waterflood path 3, arrive water filling sacculus 2, water filling sacculus 2 is heaved under the effect of water, forms the sacculus that diameter reaches 6mm; The hook of ergometer is hung on stretch ring 9, tractive this utility model cervical cempetence dynamometry traction tube, record pull strength size.This utility model cervical cempetence dynamometry traction tube is structure as a whole due to water-filling nozzle and conduit, relative to Foley conduit, saves special water filling port, alleviates the deadweight of Foley tail end of conduit, improve the degree of accuracy of dynamometry.And, water-filling nozzle is provided with stretch ring, can be connected with dynameter very easily, improve the convenience of distraction test.
