Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail.
embodiment one.
See Fig. 1-Fig. 3, the present embodiment comprises body 1, swelling gasbag 2 and locating bar 3, and the head end of body is provided with top guide 11, and this top guide 11 is tightly connected with body 1 head end, and top guide 11 is solid semielliptical shape.Body 1 front end has two ventholes 12 near the position at top guide 11 place, and swelling gasbag 2 is sealedly attached to body 1 front end, and swelling gasbag 2 entirety is positioned at top guide 11 rear, to play good fixation.It is inner that venthole 12 is positioned at swelling gasbag 2.Plunger cavity 13 and inflation cavity 14 is provided with in body 1, body 2 end is provided with an inflatable chamber interface 15 and a plunger chamber interface 16, plunger cavity 13 is connected through with plunger chamber interface 16, inflation cavity 14 is connected through with inflatable chamber interface 15, and venthole 12 is opened on the inflation cavity 14 of body 1 front end.Air valve 4 is installed on inflatable chamber interface 15.
Locating bar 3 tail end is provided with grip part 31, and locating bar 3 entirety is made up of semi-rigid plastic, also can make with semi-rigid stainless steel material.Body 1, swelling gasbag 2, inflatable chamber interface 15 and plunger chamber interface 16 adopt the silica gel material of high rigidity to make.During use, hold grip part 31 and locating bar 3 is inserted in plunger cavity 13, this expander is inserted and makes swelling gasbag 2 be placed in uterine neck place.
Body 1 is marked with scale markings 17, these scale markings 17 by centimetre in units of indicate, facilitate the intubating length of the visual sacculus cervical dilator of doctor and the location of swelling gasbag 2.
Air valve 4 described in the present embodiment selects the Bidirectional Air Valve having and take out, inflate the function of (water), during use, can according to the period needs of cervical dilatation timeliness, timesharing is progressively expanded swelling gasbag 2 and is adjusted swelling gasbag 2 amount of capacity at any time, simultaneously, cervical dilatation complete need to extract expander out time, by water extraction way, the water in swelling gasbag 2 capsule is pumped, is convenient to extract out and residual water can not to be expanded in air bag 2 capsule and be interrupted and flow out and produce contamination phenomenon.Air valve 4 is designed to dismountable, and also can be replaced with as required can the monodirectional locking air valve of screw-in, needs to select this air valve when fast aeration (water) or exhaust (water).
Swelling gasbag 2 effectively expansion heap(ed) capacity can reach 800ml, it extends the expansion amount of capacity range of choice of swelling gasbag, expand the scope of application of novel sacculus expander simultaneously, be not only applicable to the swelling gasbag expansion of the following capacity of uterus neck 300ml, also be applicable to the jumbo swelling gasbag expansion of more than 500ml, for uterus hemostasis in postpartum simultaneously.
embodiment two.
See Fig. 4, changed into the position of the swelling gasbag 2 in embodiment one: swelling gasbag 2 is sealedly attached to body 1 front end, it is inner that top guide 11 is positioned at swelling gasbag 2.All the other structures are constant.
embodiment three.
See Fig. 5-Fig. 6, the inflatable chamber interface 15 in embodiment two is made following change:
Inflatable chamber interface 15 sets up interface one 15-1 and interface two 15-2 separately, interface 15-1 is equipped with air valve 1, interface 15-2 is equipped with air valve 27, air valve 1 be can screw-in, the monodirectional locking air valve of detached type.When needs cervix dilating, can carry out inflating (water) and expanded swelling gasbag 2 by non-resistance after screwing on air valve 1; When needs take out expander fast, screwing off air valve 1 can discharge the water in capsule instantaneously and take out expander.The gas (water) in capsule can be extracted or be filled with to air valve 27, for only having, leading to the Bidirectional Air Valve of function, when needs regulate cervical dilatation size, out by air valve 27 at any time; When needs slowly take out expander, the water in capsule can be extracted lentamente out by air valve 27 and take out expander, and the residual water in capsule can be pumped in order to avoid output contamination phenomenon.Inflation (water) speed of air valve 1 is 4-6 times of air valve 27, and can arrange (gas) water instantaneously, and when checking or need Rapid Expansion in operation or take out expander fast, use air valve 1 is fast very convenient.Air valve 27 due to its venting (water) or inflation (water) speed relatively slow, be suitable for regulate swelling gasbag expansion size time use.In actual production, the periphery of inflatable chamber interface 15 and plunger chamber interface 16 all can coated reinforcement material, increases its object that the is easy-to-use and life-span to play.
Locating bar 3 changes positioning guide wire 5 into, and positioning guide wire 5 tail end is provided with crotch structure 51, and positioning guide wire 5 entirety is made up of semi-rigid stainless steel material, also can make with semi-rigid plastic.During use, hold crotch structure 51 and positioning guide wire 5 is inserted in plunger cavity 13, this expander is inserted and makes swelling gasbag 2 be placed in uterine neck place.All the other structures are all identical with enforcement two.
embodiment four.
See Fig. 7, the inflatable chamber interface inflating cavity connection in embodiment two or three changes two inflatable chamber interfaces into, be respectively inflatable chamber interface 1 and inflatable chamber interface 29, inflatable chamber interface 1 is equipped with the air valve identical with air valve 1, inflatable chamber interface 29 is equipped with the air valve identical with air valve 27.Other structure is all identical with embodiment two.
By foregoing description, those skilled in the art can implement.
Above embodiment has made comparatively detailed description to the utility model, but these descriptions are not to restriction of the present utility model, namely utility model is not limited to concrete structure and the description of above-described embodiment, combine implement as embodiment one also can set up interface structure separately with the inflatable chamber interface 15 in embodiment two, also locating bar 3 and positioning guide wire 5 can be carried out exchanging implementing.In a word, all according to the equivalence done of structure, shape and feature described in the utility model design or simple change, be included in the protection domain of the utility model patent.
