Abstract
A kind of very thin bar sacculus of compliance ventral aorta temporary interruption being applicable to obstetric operation, it is characterized in that: the sacculus connection tube comprising push rod, be arranged on the soft polyurethane material sacculus of push rod front end and be connected with sacculus, sacculus connection tube tail end is provided with valve, described soft polyurethane sacculus is low pressure compliant balloon, and described push rod is more very thin 5F type push rod.The utility model has the advantage of: 1. balloon design is compliance, utilize compliant balloon to adapt to vascular morphology this characteristic moulding, inflation can be avoided to block ventral aorta and cause relevant blood vessel to damage complication; 2. push rod is very thin, is 5F size, avoids the damage of puncture and intubation place femoral artery, more Wicresoft; 3., in operation, have easy, efficiently advantage, quantity of X-rays X suffered by fetus is greatly reduced; 4. in price, comparatively import support economy, can be patient's cost saving, special equipment in a kind of economical and practical dangerous property caesarean section with placenta previa art of can yet be regarded as.
Description
Technical field
This utility model relates to medical balloon, a kind of very thin bar sacculus of compliance ventral aorta temporary interruption being applicable to obstetric operation specifically, the relevant blood vessel damage complication caused when using sacculus of the present utility model that existing common inflation can be avoided to block ventral aorta.
Background technology
In dangerous type placenta previa person cesarean section, average bleeding is up to 3000 ~ 5000 ml, even up to 10000 more than ml, and swift and violent hemorrhage serious threat pregnant and lying-in women life security in the short time.Previously dangerous property caesarean section with placenta previa is postoperative is hemostasis and hysterectomizing, and in art, average blood loss still reaches is 4000 ~ 5000ml.For reducing hemorrhage Reservations uterus, obstetrics taked ligation internal iliac artery or uterine artery in the past, but for dangerous property placenta previa especially with the patient of Placenta acrreta, even if ligation ilium is interior or uterine artery, also fully cannot block placenta accreta blood to supply, and because amount of bleeding is large in cesarean section, in row ilium or uterine artery ligation difficulty increase.
Foley's tube technology is more and more applied to dangerous type caesarean section with placenta previa art in recent years.The application of preventative internal iliac artery Balloon Occlusion art in placenta increta case, the no matter operation of row Reservations uterus or uterectomy, in art, transfusion volume all obviously reduces.Before D & C, the two internal iliac artery Balloon Occlusion art patients of prophylactic use treat dangerous type placenta previa with conventional Cesarean esction and accompanys Placenta acrreta patient, contrast discovery preventative pair of internal iliac artery Balloon Occlusion art and can reduce the intraoperative blood loss of patient, transfusion volume and related complication.But there is following defect: 1. there is dystopy blood supply in part uterus, as ovarian artery and (or) external iliac artery participate in blood supply, blocks bilateral internal iliac merely, can not effectively control the hemorrhage of such tremulous pulse.2. before D & C because Superselective catheterization is slightly long to bilateral internal iliac spent time, expose ray suffered by increase fetus and anemia of pregnant woman to the open air dosage.3. internal iliac artery balloon occluder is postoperative, finds internal iliac artery thrombosis, and internal iliac artery interlayer causes the complication such as 80-90% vascular occlusion to occur.Therefore can design a kind of compliant balloon being exclusively used in the temporary transient shutoff ventral aorta of obstetric operation and cause concern about medical worker in the industry.
Summary of the invention
A kind of very thin bar sacculus of compliance ventral aorta temporary interruption being applicable to obstetric operation that the purpose of this utility model provides for the problem existing for above-mentioned prior art just.
The purpose of this utility model is achieved through the following technical solutions: a kind of very thin bar sacculus of compliance ventral aorta temporary interruption being applicable to obstetric operation, comprise push rod, be arranged on the soft polyurethane material sacculus of push rod front end (this balloon material is current existing sacculus common used material) and the sacculus connection tube that is connected with sacculus, sacculus connection tube tail end is provided with valve, described soft polyurethane sacculus is low pressure compliant balloon, and described push rod is more very thin 5F push rod.
In this utility model, described low pressure compliant balloon surface is covered with heparin coating, in case tampon is formed, described low pressure compliant balloon is oval.Described 5F push rod is the push rod of polrvinyl chloride material.
Foley's tube mid point in use, is placed in two renal artery opening part line mid point by this utility model before Cesarean esction, and after fetus is taken out, the ventral aorta of Filled Balloon blocking-up immediately blood supplies thus block all uterine artery blood to supply.In this blocking-up method simplify fetus take out before interventional procedure step, institute uses has an X-rayed time average 4s, and roentgendosis is 4.2 ± 2.9mGy, far below the fetal well-being X beta radiation dosage of 150 mGy.
Sacculus push rod is inserted from femoral artery, and for making Wicresoft more, sacculus push rod is very thin, is only 5F, avoids the damage of puncture and intubation place femoral artery.Blocking ventral aorta for avoiding inflation causes relevant blood vessel to damage complication, and balloon design is low pressure compliance.
In this utility model, described foley's tube is made up of push rod, sacculus, and have two independently inner chambers, guidewire lumen runs through whole piece push rod, puts sacculus for introducing seal wire, and sacculus connection chamber is used for expanding and retraction sacculus.Sacculus is low pressure compliant balloon, less to the damage of blood vessel wall, and sacculus is manufactured by soft polyurethane material, and tube material is polrvinyl chloride, built-in stainless steel spring silk.According to the individual variation of puerpera's ventral aorta diameter, appropriate diameter can be expanded to and thoroughly block ventral aorta, simple to operate, safety.
The utility model has the advantage of: 1. sacculus push rod is very thin, is only 5F, avoid the damage of puncture and intubation place femoral artery, more Wicresoft; 2. balloon design is low compliance, utilizes compliant balloon to adapt to vascular morphology this characteristic moulding, common inflation can be avoided to block ventral aorta and cause relevant blood vessel to damage complication; 3. operationally, have easy, efficiently advantage, quantity of X-rays X suffered by fetus is greatly reduced; 4., in price, comparatively import support economy, for patient saves expense.
Accompanying drawing explanation
Fig. 1 is this utility model structural front view.
In figure: 1. push rod, 2. sacculus, 3. valve, 4. sacculus connection tube.
Detailed description of the invention
Wood utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1: a kind of very thin bar sacculus of compliance ventral aorta temporary interruption being applicable to gynecilogical operation, the sacculus connection tube 4 comprising push rod 2, be arranged on the soft polyurethane material sacculus 2 of push rod front end and be connected with sacculus, sacculus connection tube tail end is provided with valve 3, described soft polyurethane sacculus is oval low pressure compliant balloon, and described push rod is the 5F push rod of more very thin polrvinyl chloride material.
During use, after push rod 1 enters ventral aorta along seal wire, inject contrast medium fill up sacculus 2 through valve 3, for blocking abdominal aorta flow to uterus blood supply after inflation, push rod end can be shifted through preventing sacculus by seal wire.
Described sacculus 2 is manufactured by soft polyurethane material, and conduit is by polyurethane material manufacture
.according to the individual variation of puerpera's ventral aorta diameter, appropriate diameter can be expanded to and thoroughly block ventral aorta, simple to operate, safety.
