Abstract
The utility model relates to a medical appliance suitable for dilating cervical canals during artificial abortion operations of the department of obstetrics and gynecology, namely a water bag cervix dilator. The utility model is characterized in that a rubber water bag pipe (3) is arranged in a water bag spacing pipe (4); the front end of a dilated water bag body (2) is connected with a dilated water bag head (1), and the rear end is connected with the rubber water bag pipe (3); whereas the other end of the rubber water bag pipe is connected with a connecting socket; the connecting socket is connected with a syringe. When the syringe injects physiological saline gradually, the dilated water bag body dilates gradually in the uterus under pushing force to realize the purpose of dilating cervices. The utility model has the advantages of simple structure, small size, low cost, safety and easy use.
Description
This utility model relates to a kind of medical apparatus and instruments, the apparatus of expansion cervix when being applicable to the department of obstetrics and gynecology artificial abortion operation---water pocket cervix dilator.
Artificial abortion operation is the maximum a kind of operation of various operation accounting example in the hospital clinical work, because softer and each body difference of gravid uterus, postoperative complications such as the perforation of uterus happen occasionally, and cervix dilator has not in the past satisfied the needs of modern clinical position: one, the tough and tensile form of employed metal dilator matter was fixed in the past; Two, the bad grasp of operating force, direction is single, and it is poor to adapt to each body physiological property; Three, the passive expansion cervix that forces makes the operation receiveing person increase misery; Four,, want repeatable operation during expansion cervix because present cervix dilator is complete combination; Five, the cervical spasm that causes of pain, particularly in stenostomy more obvious.So not only bring misery, also bring a lot of inconvenience to clinical position to the operation receiveing person.
The purpose of this utility model just provide a kind of simple in structure, easy to use, cost is low, replacing the cervix dilator of present use, thereby solves the existing deficiency of above-mentioned cervix dilator effectively.
The purpose of this utility model realizes by following proposal, 3,5 millimeters thick rubber bag with water pipes of a diameter are housed in the water pocket position-limiting tube of 4 millimeters of internal diameters do water-filling usefulness, the front end of the swollen utricule that rises is the good swollen capsule head that rises of the airtight extension performance of sealing, a connection that can be connected with syringe nipple is installed on the other end sits.Earlier disposable water balloon dilator device is put into cervical canal during clinical use and adjust to the optimum position, with pack into the normal saline of 20ML of syringe, insert to connect and sit, and inject slowly in disposable water pocket cervix dilator that (practical situation according to everyone determines its injection rate, generally 15---20 milliliters are advisable), the normal saline that injects can be with swollen the rising of the endocervical swollen capsule that rises, the swollen capsule that rises behind swollen the rising becomes diameter 14---and 16 millimeters, long 63---66 millimeters slightly crooked cylinders, and reach the purpose that makes cervical dilatation.
Accompanying drawing 1 is the sketch map according to this utility model water pocket cervix dilator.
Describe detail and the operation principle that the utility model proposes in detail below in conjunction with accompanying drawing 1.
This utility model comprises: the swollen capsule head 1 that rises, the swollen utricule 2 that rises, rubber bag with water pipe 3, water pocket position-limiting tube 4, connection sit 5.The effect of swollen rise capsule head 1 and the swollen utricule 2 that rises: mainly be that injection owing to liquid makes its swollen rising realize the purpose of expansion cervix.Rubber bag with water pipe 3 is the passages that normal saline imported the swollen utricule 2 that rises.The effect of water pocket position-limiting tube 4: because it has certain rigidity, and make the swollen utricule 2 that rises successfully insert in the cervical canal, after the insertion water pocket position-limiting tube is drawn back, the swollen utricule 2 that rises is stayed in the cervical canal, when in the swollen utricule that rises, injecting normal saline,, and stay the swollen chap of rising of the swollen body that rises of intracervical water pocket because the effect of water pocket position-limiting tube maintains the original state the part in the water pocket position-limiting tube, with cervical dilatation, artificial abortion operation is carried out smoothly.Connect sitting 5 is to make itself and syringe easy to connect and be provided with.
This utility model is to realize the cervical canal expansion like this, should at first adjust the position of swollen rise capsule head 1 and water pocket position-limiting tube 4 during use, make the front end of the swollen capsule head 1 that rises, slightly be longer than water pocket position-limiting tube 4, the water pocket cervix dilator is inserted (the water pocket position-limiting tube should be inserted into interior 3 millimeters of the external os of vervix) in the cervical canal, live to connect with a handgrip then and sit 5, the another hands with water pocket position-limiting tube 4 to pulling back out 30 millimeters, make it to sit 5 near connecting, can connect syringe slowly injects normal saline, make swollen rise utricule in cervical canal by slow swollen the rising of pushing force, and realize the purpose of expansion cervix.
This utility model is simple in structure, volume is little, cost is low, safe and reliable, easy to use, more adapt to disposable promoting the use of.Also very great achievement degree ground alleviates operation receiveing person's misery, guarantees safety medical treatment.
