Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to disposable amniocentesis remaining needle.
Background technology
Oligohydramnios, polyhydramnios, fetal distress are obstetrics' common problem.During oligohydramnios, the perinatal fetal mortality obviously increases, fetal anomaly (carcass adhesion, fetus m usculoskeletaldisorder etc.) is often caused at pregnant early metaphase, often cause fetal anoxia pregnant late period, the poverty-stricken Perinatal morbidity that makes is bad, and often cause cesarean delivery rate rising, if use amniotic cavity perfusion fluid method to treat, can prolong pregnancy week, reduce fetal anomaly, anoxia occurs, improve Fetal prognosis, reduce cesarean delivery rate.If polyhydramnios can cause gravid uterus to increase, cause uterus tension force too high, easy generation premature labor, premature rupture of fetal membrane, postpartum hemorrhage etc., perinatal mortality rate is increased, in order to avoid the adverse effect that polyhydramnios causes, obstetrist can bleed off the too much amniotic fluid of part, i.e. so-called amniotic fluid drain, reduces the generation of badness come-off.Fetal distress is often with Contamination of Amniotic Fluid by Fetal Feces, clinical showing implements Amnioinfusion in amniotic cavity, excrement is contaminated amniotic fluid displace in time external when can make product fetal rhythm seriously make a variation and slow down, alleviate or alleviate fetal distress in uterus, prevention Meconium aspiration syndrome, reduces perinatal mortality rate etc.
But, no matter amniotic fluid perfusion, amniotic fluid drain or Amnioinfusion, the amniotic cavity puncture needle of current Clinical practice is that waist wears puncture needle, connects thereafter syringe and repeatedly aspirates (perfusion), operation effort during use, the easy slippage of puncture needle goes out amniotic cavity, sometimes need secondary puncture, the risk adding infection, miscarriage and damage, too increases the misery of patient, when operating, draw point stays in amniotic cavity, easily causes fetal damage.Do not seeing relevant disposable amniocentesis indwelling needle device on the market now.
Utility model content
In order to overcome the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of disposable amniocentesis remaining needle, and this containing needle structure is reasonable in design, simple to operate, and safety is high, and indwelling is effective.
This utility model is achieved through the following technical solutions:
Disposable amniocentesis remaining needle, comprises puncture needle, is provided with nook closing member in puncture needle, and nook closing member end is provided with needle core handle; Conduit is arranged with outside puncture needle, the tip of puncture needle can be stretched out from catheter proximal end, and catheter tip is provided with opening, and conduit separates a road arm from opening, this arm connects a Y-type three way type, and two other arm of this Y-type three way type connects amniotic fluid drainage tube and delivery tube respectively.
The external extension tube of a road arm that conduit separates from opening, extension tube is connected with an arm of described Y-type three way type.
The pipeline of extension tube is also provided with water-stop.
Amniotic fluid flow sub and administration joint is respectively equipped with at the end of amniotic fluid drainage tube and delivery tube.
Delivery tube is provided with filter.
Bottom puncture needle, be also provided with hand holding handle, the surface of this hand holding handle is provided with some non-slip process.
Sheath is provided with outside puncture needle.
The length of described puncture needle is 15 ~ 20cm.
The sidewall of catheter proximal end is provided with some secondary orifices, is marked with scale at conduit external standard.
Puncture needle and nook closing member are made up of steel material, and conduit is made up of medical plastic.
Compared with prior art, this utility model has following useful technique effect:
Disposable amniocentesis remaining needle disclosed in this utility model, first, at the outer sheathed conduit of puncture needle, during use, the tip of puncture needle is stretched out from the front end of conduit, puncture needle can penetrate in amniotic cavity by guide catheter, by catheter retaining in amniotic cavity, effectively can avoid the risk of steel puncture needle damage fetus over the course for the treatment of; Secondly, the external extension tube of conduit branch can make the operation of amniotic cavity drain and perfusion medicine away from point of puncture, and extension tube Surgidressing can be fixed on skin surface, decrease the risk of conduit slippage, avoid repeated localised puncture, decrease infection that secondary puncture patient bears, miscarriage and damage risk, add comfortableness and safety.Finally, the design of Y-type three way type, can realize amniotic cavity perfusion administration and amniotic fluid drain two-way carries out, and treatment is operated more convenient.This remaining needle is reasonable in design, simple operation, single use, can effectively reduce patient infection's probability, make amniotic cavity drain, perfusion drug treatment safer.
Further, conduit can an external extension tube on the road arm that opening separates, and increases length.This extension tube is provided with water-stop, can the speed of the drain of regulating and controlling amniotic fluid and amniotic fluid perfusion administration, make therapeutic process controllability stronger, add the safety for the treatment of.
Further, bottom puncture needle, be also provided with hand holding handle, the surface of this hand holding handle is provided with some non-slip process, can increase the convenient of operation and safety.
Further, delivery tube is also provided with filter, can stops that impurity enters amniotic cavity, add the safety for the treatment of, reduce patient infection's probability.
Further, the sidewall of the front end of conduit is provided with some secondary orifices, when catheter proximal end main opening is blocked, secondary orifices can work on.Conduit is marked with scale simultaneously, the degree of depth entered in amniotic cavity can be shown, effectively play indicative function.
