Description

Urinary system expansion drainage device

Technical Field

The utility model relates to the field of medical equipment, concretely relates to urinary system expansion drainage device.

Background

Ureteral stenosis is a common disease in clinical urology surgery, and is mostly due to obstructive lesion of a knife caused by contracture of a ureteral cavity of an organism. The occurrence of ureteral stenosis can cause upper urinary tract hydrops, damage kidney function and even cause renal failure to endanger the life of a patient.

The use of balloon dilation is an emerging technique for treating ureteral stenosis, in which the ureter is dilated by a balloon to dilate the internal diameter of the ureter and restore the patency of the ureter.

The existing balloon dilatation can be expanded to the periphery as uniformly as possible during expansion, and cannot perform targeted expansion on contracture positions.

The utility model aims to overcome the problems and provide a urinary system expanding drainage device. In order to achieve the above purpose, the utility model adopts the following technical scheme:

a urinary system dilation drainage device comprises a drainage tube and an air bag, wherein the front end of the drainage tube is provided with a drainage head, the tail end of the drainage head is provided with a connector, and the air bag is arranged at the outer side of the drainage tube and close to the drainage head;

the air bags comprise a plurality of sub air bags, each sub air bag supplies air independently and is provided with an independent air supply pipe, the tail end of each air supply pipe is provided with an air supply joint, and each air supply joint is provided with a control valve;

an outer sleeve for wrapping the air bag is arranged on the outer side of the drainage tube.

As an improvement, the bottom of the sub-air bag is larger than the top of the sub-air bag, and two sides of the sub-air bag are provided with folded parts.

As an improvement, the outer sleeve is made of a high-elasticity material, and the air bag is made of a low-elasticity material.

As an improvement, the front end of the drainage head is provided with a drainage hole, and the two sides of the drainage head are provided with side holes.

As an improvement, the inner side of the outer sleeve and the outer side of the drainage tube are arranged at intervals, the air supply pipe penetrates through the interval between the outer sleeve and the drainage tube, and a plurality of connection points are arranged between the outer sleeve and the drainage tube.

As a modification, the number of the control valves is the same as that of the air supply pipes, and the opening and the closing of the corresponding air supply pipes are controlled independently.

The utility model discloses an excellent lie in:

the utility model discloses can carry out the targeted expansion to certain direction or some directions. The utility model has good expansion effect on the ureter, simple operation and wide application in clinical treatment.

Detailed Description

The present invention will be described in detail and specifically with reference to the following examples so as to provide a better understanding of the present invention, but the following examples do not limit the scope of the present invention.

Example 1

The embodiment discloses a urinary system expansion drainage device, which comprises a drainage tube 1 and an air bag 2. The front end of the drainage tube 1 is provided with a drainage head 11, and the tail end of the drainage head is provided with a connector 12. The front end of the drainage head 11 is provided with a drainage hole 111, and two sides are provided with side holes 112. The air bag 2 is arranged at the outer side of the drainage tube 1 near the drainage head 11.

The airbag 2 includes four sub-airbags 21. Each sub-air bag 21 is independently supplied with air and provided with a separate air supply pipe 22. The end of the air supply pipe 22 is provided with an air supply joint 23, and the air supply joint 23 is provided with a control valve 24. The bottom of the sub-bag 21 is larger than the top, and both sides are provided with folded parts 25. The number of the control valves 24 is the same as the number of the air supply pipes 22, and the opening and closing of the corresponding air supply pipes 22 are individually controlled.

An outer sleeve 3 which wraps the air bag 2 is arranged at the outer side of the drainage tube 1. The inner side of the outer casing 3 and the outer side of the drainage tube 1 are arranged at intervals, and the air supply pipe 23 is arranged between the outer casing 3 and the drainage tube 1 in a penetrating way. A plurality of connecting points 31 are arranged between the outer casing 3 and the drainage tube 1.

In this embodiment, the outer tube 3 is made of a highly elastic material, and can be changed in shape according to the inflation state of the sub-bag 21. The air bag 2 is made of low-elasticity materials, only depends on the folding part 25 to expand and deform, can keep the shape after being inflated, and generates directional expansion effect on the designated direction.

The present invention has been described in detail with reference to the specific embodiments thereof, which are provided by way of example only, and the present invention is not limited to the specific embodiments described above. Any equivalent modifications and substitutions to those skilled in the art are also within the scope of the present invention. Therefore, the equivalent changes and modifications without departing from the spirit and scope of the present invention should be covered by the scope of the present invention.
