Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

The three-cavity urinary catheter comprises a three-cavity urinary catheter 1, wherein the left side of the three-cavity urinary catheter 1 is a washing pipe 2, the upper end of the washing pipe 2 is a washing opening 3, an annular rubber pad 4 which is positioned at the end of the washing opening 3 is arranged in the washing opening 3, a rubber ring 5 which is positioned below the rubber pad 4 is arranged in the washing opening 3, a leakage-proof ring 6 which is positioned below the rubber ring 5 is arranged in the washing opening 3, and threads 7 which are arranged along the axis direction of the washing pipe 2 are arranged on the outer edge surface of the upper side of the washing pipe 2.

In order to ensure that the rubber pad 4 is matched with the rubber ring 5 for use and has a leakage-proof effect, the inner diameter of the rubber pad 4 is smaller than that of the rubber ring 5, and the distance between the rubber pad 4 and the rubber ring 5 is shorter.

In order to further play a role of leakage prevention, the leakage prevention ring 6 is made of rubber, and the inner diameter of the leakage prevention ring is smaller than that of the rubber pad 4.

In order to play a role of protection, the outer side of the flushing pipe 2 is connected with a protective sleeve 8 through a thread 7, and the outer side of the protective sleeve 8 is movably connected with an end cap 10 positioned at the upper end of the protective sleeve through a buckle 9.

In order to play a role in sealing, the end cap 10 has elasticity and is in interference fit with the protective sleeve 8, and an annular clamping block 16 which can be matched with the buckle 9 is arranged in the end cap 10.

For convenience in use, a first annular groove 11 located below the thread 7 is formed in the outer side of the flushing pipe 2, a first fixing ring 12 is connected in the first annular groove 11 in a rotating mode, a second annular groove 13 is formed in the outer side of the end cap 10, a second fixing ring 14 is connected in the second annular groove 13 in a rotating mode, and the first fixing ring 12 is connected with the second fixing ring 14 through a plastic rope 15.

In order to be conveniently matched for use, the washing pipe 2 is communicated with the three-cavity urinary catheter 1, and the other two pipelines of the three-cavity urinary catheter 1 are the same as the existing structure.

When the utility model is started, the protective sleeve 8 is connected with the outer side of the flushing pipe 2 through the thread 7, the upper end of the protective sleeve 8 is movably connected with the end cap 10 through the buckle 9, and the end cap 10 is in interference fit with the protective sleeve 8 in order to prevent the end cap 10 from slipping from the upper end of the protective sleeve 8;

the utility model is connected with the body of a patient in the same way as the existing three-cavity urinary catheter 1;

when the bladder of a patient needs to be flushed, the end cap 10 is forcibly taken down from the upper end of the protective sleeve 8, and the outer side of the end cap 10 is rotatably connected with a second fixing ring 14 through a second annular groove 13, and the second fixing ring 14 is connected with a first fixing ring 12 through a plastic rope 15, so that the end cap 10 is connected to the flushing pipe 2, and the end cap 10 is prevented from being lost;

after the end cap 10 is taken down, the front end of the injector is inserted into the flushing port 3, and because the diameter of the front end of the injector is larger than the inner diameter of the rubber pad 4, when the front end of the injector is inserted into the flushing port 3, the rubber pad 4 is downwards extruded to deform and contact with the rubber ring 5 below the rubber pad, and under the support of the rubber ring 5, the outer edge surface of the front end of the injector is in close contact with the upper surface of the deformed rubber pad 4, so that the leakage-proof effect is achieved;

when the front end of the injector is continuously inserted downwards, the inner diameter of the leakage-proof ring 6 is smaller than that of the rubber pad 4, so that the leakage-proof ring 6 can clamp the front end of the injector, at the moment, the leakage-proof ring 6 and the rubber pad 4 are fixed in two points, the whole leakage-proof effect is more effective and stable, after the front end of the injector is completely inserted into the flushing port 3, flushing liquid in the injector can be injected into the flushing pipe 2, the bladder of a patient is flushed, and the side leakage can not occur, after the flushing operation is finished, the end cap 10 is sleeved outside the protective sleeve 8 again, and is in interference fit with the outer side of the protective sleeve 8 through the buckle 9, so that the end cap 10 is prevented from slipping;

when the flushing port 3 needs to be connected with a screw infusion apparatus, the protective sleeve 8 on the outer side of the flushing pipe 2 is rotated and taken down, the thread 7 on the outer side of the flushing pipe 2 is exposed, and the second fixing ring 14 is rotatably connected with the first annular groove 11, so that when the protective sleeve 8 is rotated and taken down, the plastic rope 15 on the outer side cannot block the rotating and taking-down action, and the use of medical staff is facilitated;

after the screw thread 7 in the flushing pipe 2 outside exposes, with the screw thread 7 end of screw infusion apparatus and the outside screw thread 7 of flushing pipe 2 be connected, the part in the screw infusion apparatus inserts flushing port 3, when inserting in flushing port 3 with the syringe, it is the same to press from both sides tight operation, so can realize that flushing pipe 2 is applicable to different transfusion system and syringe, after the operation of washing, again with lag 8 and flushing pipe 2's outside screw thread 7 be connected, prevent lag 8 or end and emit 10 slippage to reduce the risk of catheter exogenous infection.

Compared with the prior art, the beneficial effects of the utility model are that: the outer side of the flushing pipe is provided with threads which can be matched with a screw infusion apparatus for use, the rubber pad and the leakage-proof ring are arranged in the flushing port, and the flushing pipe is clamped by the deformation of the rubber pad and the leakage-proof ring, so that the flushing pipe can be effectively matched with various infusion apparatuses and injectors for use, has a leakage-proof function, avoids exogenous infection during storage, avoids the operation of matching with various infusion apparatuses or injectors after a rubber plug is inserted into the flushing port, and is more convenient for the operation of medical personnel; the structure is simple, the operation is convenient, the conception is novel, and the practicability is strong.
