Description

The postoperative anti-sticking balloon-stent in uterus

Technical field

The utility model relates to medical instruments fields, and in particular to a kind of postoperative anti-sticking balloon-stent in uterus.

Background technique

The existing postoperative balloon-stent in uterus: cook sacculus is a silica gel support with sacculus.Including silica gel hose and The swelling sacculus bag of the triangle sample of front end, silica gel hose end connect the rubber stopper of a single-pass.In use, longitudinal roller ball capsule To diameter as small as possible, the top of roller ball capsule is then caught with smooth forceps.Binding clip with sacculus is inserted by cervical canal Enter uterine cavity above uterine neck internal orifice, part Filled Balloon.It gently pulls back smooth forceps, sacculus is left in place.Then Filled Balloon.Stop The time is stayed to must not exceed 1 week.Its disadvantage is as follows；1:cook balloon surface protrudes from hose and is individually present, when rolling volume with smooth forceps It can not be reduced to ideal noise diode, for another cook sacculus because of the silica gel material that its silica gel produced and used is inclined hard ground, surface is slightly coarse, Patient strong sense of discomfort and feeling of pain when this two o'clock causes sacculus to pass in and out vagina and cervix opening.Uterine cavity is prevented after 2 hysteroscope operations Inside it is adhered and needs to place IUD(intrauterine device) or cook sacculus, but sacculus standing time in uterine cavity is limited (generally not More than 1 week), and cook sacculus can not with IUD simultaneously be placed into uterine cavity (due to cook sacculus be triangle, fill when it is direct Uterine cavity is filled with, IUD can not be put down), after causing cook sacculus to place maximum time taking-up, without any supporting substances in uterine cavity The uterine cavity not healed completely is caused to be adhered.The patient of cook sacculus, pain scores one after most is awake are placed in 3 arts For degree up to 7-10 points, this is very huge insufferable pain for patient.

Summary of the invention

The utility model is in view of the above-mentioned problems, provide a kind of postoperative anti-sticking balloon-stent in uterus.

Technical solution adopted in the utility model is as follows: a kind of postoperative anti-sticking balloon-stent in uterus, including conduit, described Conduit is double-layer tube, and guiding tube and outer layer including internal layer are covered with the elastomer of guiding tube, and the elastomer is opened for one end Mouthful and the tubulose that is adapted to guiding tube, the elastomer sleeve be fixedly connected outside guiding tube and in open at one end with guiding tube, institute It states and forms the variable blister cavities of size between guiding tube front end and elastomer, be equipped with waterflood path, the guidance in the guiding tube Pipe is equipped with water filling port, the water filling port connection blister cavities and waterflood path.

The elastomer sleeve is connected by way of bonding in open at one end and guiding tube.

The guiding tube forward end is smooth surface, and the water filling port is arranged in guiding tube side.

The water filling port is two and is symmetrical arranged.

Check valve is connected on the guiding tube.

The conduit is equipped with the marking line for indicating injection rate.

The beneficial effects of the utility model are as follows: 1, sacculus is the elastomer composition for being covered with guiding tube, in unimplanted water Shi Buhui is convex in conduit, does not have that generate local friction larger and cause uncomfortable or pain feeling because sacculus is heaved, makes With conveniently, high degree facilitates doctor's operation and considerably reduces the sense of discomfort of patient；2, after blister cavities is full between uterine cavity There are still the spaces for putting down IUD, and do not influence IUD effect in place after taking out sacculus, extend the time for preventing uterine cavity to be adhered.

Specific embodiment

With reference to the accompanying drawing and specific embodiment, the utility model can be better described.

A kind of postoperative anti-sticking balloon-stent in uterus, including conduit, the conduit are double-layer tube, the guiding tube including internal layer 1 and outer layer be covered with the elastomer 2 of guiding tube 1, the elastomer 2 is tubulose that is open at one end and being adapted to guiding tube 1, described 2 sets of elastomer is outer in guiding tube 1 and is fixedly connected in open at one end with guiding tube 1,1 front end of guiding tube and elastomer 2 it Between form the variable blister cavities 3 of size, waterflood path 101 is equipped in the guiding tube 1, the guiding tube 1 is equipped with water filling port 102, the water filling port 102 is connected to blister cavities 3 and waterflood path 101.

The elastomer 2 is connect by way of bonding in open at one end with guiding tube 1.It can also be solid by peripheral hardware clip Fixed or other common structures, the influence connected by way of bonding to conduit outer shape are smaller.From the opening of elastomer 2 one End makes the two keep connection to close to this section of the position of water filling port 102 by way of bonding, connects closer, reliable.

1 forward end of guiding tube be smooth surface, patient's body of entering in this way comfort level more preferably, the water filling port 102 are arranged in 1 side of guiding tube.The end in 1 front end of guiding tube also can be set in water filling port 102.

The water filling port 102 is two and is symmetrical arranged.It is more uniform when full in this way.

Check valve 4 is connected on the guiding tube 1.

The conduit is equipped with the marking line for indicating injection rate.Marking line can be set on guiding tube and elastomer is transparent Visual, also it can be arranged directly on elastomer.

Before use, catheter surface is smooth state, even thickness.When injecting the sterile water of mark amount in the catheter, Sterile water will pass through waterflood path, be extruded from water filling port, into the blister cavities formed between guiding tube front end and elastomer, make Blister cavities sufficiently expands, and allows it to seal in intrauterine and positions.During fabrication, as long as double-layer hose is made to have one section of part not to be bonded in one It rises, one can be formed be equivalent to and be hidden in supravasal sacculus, one-pass molding, structure is simple, convenient for manufacture.In conduit depth When entering to vagina and uterus, do not have that generate local friction larger and cause uncomfortable or pain feeling because sacculus is heaved, Easy to use, high degree facilitates doctor's operation and considerably reduces the sense of discomfort of patient.

The difference of the utility model is explicitly shown according to preoperative and postoperative AFS scoring (uterine cavity is adhered degree scoring) difference data Value is bigger than the difference of simple cook sacculus, illustrates that effect is better than cook sacculus.The comparison of postoperative patient pain scores, cook sacculus Pain scores are apparently higher than the pain scores of the balloon-stent+IUD of our inventions, are placed in most patient's art of cook sacculus Pain is fairly obvious afterwards or even some patient can not bear the pain and require to take out cook sacculus immediately, the ball that we invent Capsule bracket improves postoperative pain unbearably this fatal defects.Bracket can be used tender texture silica gel and (two kinds of elastic forces be made Silica gel prepared respectively as guiding tube 1 and elastomer 2), patient's pain can be reduced with high degree.

The foregoing is merely an embodiment of the present invention, are not used to limit the protection scope of the utility model； The protection scope of the utility model is limited by the claim in claims, and all according to equivalent made by utility model Variation and modification, all within the protection scope of the utility model patent.
