It changes pipe fitting 2 to be connected with one end of tube body 1, change pipe fitting 2 with central passage 21 and cuts central passage 21 Disconnected spool 22.Spool 22 is fixed in central passage 21.Spool 22 is equipped with opening portion 221, and opening portion 221 can be in external device It is close to the side of the external device when across the opening portion 221, realizes air seal, and is automatic after the external device is extracted Closing, to keep air seal.In a specific application implementation mode, above-mentioned external device for example can be interior peep Mirror.
In the present embodiment, the inner wall of the side of spool 22 and central passage 21 is interference fitted.As shown in figure 3, opening portion 221 be joint-cutting, and the shape of joint-cutting is linear type, but not limited to this, the shape of joint-cutting is also possible to cross, T-shaped or Y word Shape.
It is equipped with it is preferred that changing pipe fitting 2 for limiting the mobile spool position limiting structure of spool 22.The spool position limiting structure The pressing plate that step surface 210, pressing plate 23 and limitation pressing plate 23 including being set to the annular of 21 side wall of central passage move up Spool position limiting structure.Spool 22 is pressed on the step surface 210 of annular.The bottom surface of pressing plate 23 is pressed on spool 22, the material of pressing plate 23 Rigid plastics can be used in matter.During pressing plate 23 is equipped with the short transverse extension along pressing plate 23, passes through for external device above-mentioned Heart through-hole 231.Pressing plate position limiting structure is the first annular projection 211 being arranged on 21 inner wall of central passage for changing pipe fitting 2, the One annular projection 211 is against the upper surface of pressing plate 23.
Further, changing pipe fitting 2 further includes sealing element 24, and sealing element 24 is fixed in central passage, and is located at spool 22 lower section.Sealing element 24 is equipped with the short transverse extension along sealing element 24, leads to for the center that external device above-mentioned passes through Hole 241, and when above-mentioned external device is inserted into the central through hole 231, the hole wall of the central through hole 241 and the side of external device The leakproofness of the device for replacing Gastroenteritic pipe of the present embodiment, Er Qieneng so not only can be enhanced in wall interference fit User is enough set to obtain good operating handle when operating external device.Pipe fitting 2 is changed to be additionally provided with for limiting the shifting of sealing element 24 Dynamic sealing element position limiting structure.In the present embodiment, the inner wall of the side of sealing element 24 and central passage 21 is interference fitted.Sealing Part position limiting structure is the second annular projection 212 being arranged on 21 inner wall of central passage for changing pipe fitting 2, the second annular projection 212 seal against the upper surface of part 24.In example in figure, the central through hole 241 of sealing element 24 is in rounding mesa-shaped, in order to The insertion of external device.
The material of spool 22 and sealing element 24 can be silica gel, thermoplastic elastic body.
Tube body 1 passes through air bag 3, and air bag 3 and is connected close to the other end of tube body 1 with the side wall of tube body 1.Pipe Body 1 includes the filling channel 12 for being located at the central through hole 11 of body central and being arranged on tube wall;Central through hole 11 with The central passage 21 for changing pipe fitting 2 is connected to, and filling channel 12 is connected to air bag 3 and inflation exhaust valve 4 respectively, utilizes injection Device can realize the inflation and exhaust to air bag 3 by inflation exhaust valve 4.In a kind of specific embodiment, inflation Exhaust valve 4 has spool and abuts connected spring with spool, and the end of syringe overcomes the elastic force of spring to depress spool Inflation or exhaust can be achieved afterwards, after removing syringe, the spool for inflating exhaust valve 5 can be automatic under the action of the elastic force of spring It resets, and then closes inflation exhaust valve 4.PVC or TPU (thermoplastic polyurethane elastomer rubber can be used in the material of air bag 3 Glue);Changing pipe fitting 2 can be realized by way of heat seal with tube body 1 and be connect with tube body 1, air bag 3, but not limited to this.
Constraint pad 5 is set on tube body 1, and constraint pad 5 is salable for being inserted into around the abdominal incision of Gastroenteritic pipe Skin area enters abdominal incision to avoid outside ambient air.Frictional force between constraint pad 5 and tube body 1 can make to constrain pad 5 Relative position between tube body 1 remains unchanged, and only in the case that external force overcomes the frictional force, constraint pad 5 and tube body 1 are Relative sliding can be generated.
In the present embodiment, constraint pad 5 includes collar portion 51 and from the outwardly extending gasket portion in the bottom of collar portion 51 52, collar portion 51 is set on tube body 1.The inner peripheral surface of collar portion 51 is equipped with annular projection 511, and annular projection 511 can increase Frictional force between the inner peripheral surface of collar portion 51 and the outer peripheral surface of tube body 1.In example in figure, the quantity of annular projection 511 It is two, silica gel can be used in the material of constraint pad 5, but not limited to this.
In the clinical use present invention, first the Gastroenteritic pipe being replaced will be needed to take away, it then will be real according to the present invention The tube body lower part for applying the device for replacing Gastroenteritic pipe of example is inserted into stomach or enteron aisle by fistulization oral.Air bag at this time 3 not yet inflate, therefore can follow in one of the insertion stomach of tube body 1 or enteron aisle.Then, by external syringe to air bag 3 Inflation, heaves air bag 3 and is tightly attached to stomach/enterostomy stoma inner wall, and then stomach or intestines is enable to touch the inner wall in abdominal cavity, together When manual slip constrain pad 5, make constrain pad 5 gasket portion 52 be tightly attached on patient abdomen skin, to keep sealing, avoid Outside ambient air enters abdominal incision.After loosing one's grip, constraining the frictional force between pad 5 and tube body 1 can make to constrain pad 5 and tube body 1 Between relative position remain unchanged, to can ensure that stomach or intestines can touch the inner wall in abdominal cavity.Then, endoscope is connect from pipe is changed It is inserted at first 2, until protruding into the stomach of patient or the target area of enteron aisle, then seal wire will be guided to be inserted into the target by the channel in endoscope Area.Guidance seal wire is retained in target area, and endoscope is withdrawn from into human body.Constraint pad 5 is unclamped, air bag 3 is deflated, by basis The device for replacing Gastroenteritic pipe of the embodiment of the present invention is withdrawn from, then along the Gastroenteritic of guidance seal wire insertion replacement Pipe finally withdraws from guidance seal wire, completes the displacement work of Gastroenteritic pipe.
Fig. 5 shows the diagrammatic cross-section of the device for replacing Gastroenteritic pipe according to a second embodiment of the present invention. The second embodiment and above-mentioned first embodiment the difference is that, constrain the entire bottom surface and one of the gasket portion 52 of pad 5 The one side bonding of cloth insertion sheet 6 is connected, and cloth insertion sheet 6 is equipped with the through-hole passed through for tube body 1.The another side of cloth insertion sheet 6 makes Used time is pasted on the skin of abdomen of patient, and covers the surrounding dermal area for being inserted into the abdominal incision of Gastroenteritic pipe, To realize the purpose of excellent sealing, outside ambient air is avoided to enter abdominal incision.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies Within, then the present invention is also intended to include these modifications and variations.
