Detailed Description
Detailed description of the preferred embodimentsthe following detailed description of the present invention will be given with reference to the accompanying drawings 1-9, but it should be understood that the scope of the present invention is not limited to the specific embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
The invention provides a flushing drainage device for treating vesicovaginal fistula, which comprises an outer tube 1, a guide strip 2 is arranged in the outer tube 1, one end of the guide strip 2 is hinged to the middle of one end of the outer tube 1 positioned in the fistula, the other end of the guide strip 2 extends to one end of the outer tube 1 positioned outside the human body, the upper and lower side surfaces of the guide strip 2 are fixedly connected with elastic diaphragms 3, the elastic diaphragms 3 at the lower side of the guide strip 2 are hermetically connected with the inner wall of the outer tube 1 and form a drainage tube 4 together with the inner wall of the outer tube 1, the elastic diaphragm 3 on the upper side of the guide strip 2 is connected with the inner wall of the outer tube 1 in a sealing way and forms a flushing tube 5 together with the inner wall of the outer tube 1, the outer end of the outer pipe 1 is respectively connected with a flushing device 6 and a negative pressure drainage device 7 through a tee joint 9, and an adjusting mechanism 8 for adjusting the position of the guide strip 2 is further arranged on the side wall of the outer pipe 1 close to the outer end.
In the embodiment, the guide strips 2 are arranged in the outer tube 1, the end parts of the guide strips 2 are hinged with the inner wall of the outer tube 1 through the hinged shaft, so that the guide strips 2 can move towards two directions to realize the separation of the outer tube 1 into two independent inner cavities which are respectively used as the drainage tube 4 and the flushing tube 5, the internal capacities of the drainage tube 4 and the flushing tube 5 are increased through the position change of the guide strips 2, the inner diameter of the outer tube 1 is not required to be increased, and the liquid of the two pipelines is sealed and isolated through the elastic membrane 3 without mutual influence and pollution, because the flushing drainage tube is required to be arranged in the fistula to realize better drainage and more thorough flushing, the insertion difficulty of the flushing drainage tube is smaller, the treatment comfort level of a patient is increased, but if the two tubes adopt two independent pipelines to perform intubation twice respectively to increase the pain of the patient, if the same pipeline is used for flushing and drainage, when a blockage blocks the pipeline in the drainage object, and then flushing is carried out, the blockage can be flushed into the fistula by flushing liquid, the purposes of thorough cleaning and drainage cannot be realized, and the smoothness of the fistula cannot be ensured, so that the drainage device can not only realize quick flushing and drainage by arranging the outer pipe 1 with a proper inner diameter, but also change the capacity of a drainage channel or a flushing channel in the outer pipe 1, and can avoid the risk of adsorption to peripheral tissues of the fistula under the action of negative pressure for the drainage tube because the inner diameters of the drainage tube and the flushing tube are gradually enlarged outwards from one end positioned in the fistula, and meanwhile, if a pus-shaped object or the blockage exists in the fistula, the pipeline blockage can be effectively avoided due to the gradual increase of the pipe diameter, and the drainage can be smoothly completed; for the flushing pipe, flushing liquid enters the end part of the flushing pipe positioned in the fistula through the outer end of the flushing pipe, more liquid can be contained due to the large diameter of a liquid inlet of the flushing pipe, but the pipe diameter is gradually reduced along with the inward pushing of the liquid and gathered towards the middle part, so that the pressure of the flushed liquid is increased, the pressurized liquid has certain impulsive force after flowing out of the drainage pipe, and the flushing effect is better;
it should be noted that the length of the guide bar 2 of the present invention is not less than the length of the outer tube 1, and the width of the guide bar 2 is less than the inner diameter of the outer tube 1, which can be specifically determined according to the requirement;
secondly, the guide strip 2 is arranged in the middle of the outer pipe 1, and can be used for flushing and draining at the same time, and the state is suitable for the condition that the flushing liquid amount and the drainage liquid amount are small.
Wherein, the one end that outer tube 1 is located the fistula is the seal end, the one end that outer tube 1 is close to the seal end is equipped with a plurality of through-holes, gib block 2 articulates the seal end at outer tube 1. When in washing, the liquid of the washing pipe is sprayed out from the through hole, so that the washing area and the washing efficiency are increased; during drainage, the through hole can avoid the damage of negative pressure to the peripheral tissue of fistula.
In order to change the position of the guide bar 2 without disassembling the tee, the adjusting mechanism 8 includes a male screw tube 81 provided on the outer tube 1, an adjusting cap 82 is screwed to the male screw tube 81, a draw bar 83 is fixedly connected to the guide bar 2, one end of the draw bar 83 is fixed to the guide bar 2, and the other end of the draw bar 83 is disposed in the adjusting cap 82 through a bearing.
Wherein, the adjusting mechanism 8 is an electric push rod.
Wherein the outer tube 1 is a soft medical catheter.
Wherein, the inner surface of the outer tube 1 and the outer surface of the elastic diaphragm 3 are both provided with waterproof coatings.
Wherein, the outer surface of the outer tube 1 is provided with a lubricating layer.
In summary, compared with the prior art, the invention has the beneficial effects that: according to the flushing drainage device, the guide strip capable of changing the position is arranged in the flushing drainage tube, so that the flushing drainage tube can be converted into the drainage tube or the flushing tube without increasing the diameter of the flushing drainage tube, convenience and practicability are realized, the clinical operation difficulty is reduced, and the comfort level of a patient is improved.
According to the invention, through the position change of the guide strip, the holding capacity of the drainage tube and the flushing tube is increased under the condition that the pipe diameter of the outer pipe is not changed, and the pipe diameter is gradually increased from inside to outside, so that the problem of pipeline blockage can be effectively avoided, and the impulsive force of flushing liquid can be increased;
according to the invention, the elastic diaphragms are arranged on the two sides of the guide strip, so that the position transformation of the guide strip is not influenced, and the complete separation of the two pipe bodies can be realized;
the guide strip is arranged in the middle of the outer tube, can be used for flushing and draining at the same time, and is suitable for the condition that flushing liquid and drainage liquid are less;
the invention realizes the rapid adjustment of the position of the guide strip through the adjusting mechanism.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
