Description

Drainage tube capable of automatically stretching and retracting

Technical Field

The utility model relates to a drainage tube especially relates to a drainage tube that can stretch out and draw back automatically.

Background

The drainage tube is a medical appliance for clinical surgery drainage, which guides pus, blood and liquid accumulated in human tissues or body cavities to the outside of the body, prevents postoperative infection and promotes wound healing. The drainage tube is widely used in various clinical departments, especially general surgery department, and as the wound area of the general surgery department is large, more penetrating fluid such as bile, intestinal juice, bleeding and the like is generated, the abdominal cavity infection is easy to occur, the illness state of a patient is delayed, the treatment effect is influenced, and medical disputes can be caused. In order to meet the treatment requirements of patients in general surgery, various drainage tubes are adopted for treatment. The reasonable placement of the drainage tube can effectively prevent the infection of patients and reduce the probability of postoperative complications. Conversely, if drainage is not appropriate, serious complications can result.

Most of the current clinical drainage tubes belong to a single straight drainage tube, are fixed through skin sutures, and are easy to fall off due to careless traction, which is one of the defects. Meanwhile, due to factors such as inadvertent pressing and bending, the drainage tube is easy to be broken and blocked, and the drainage is not smooth, which is the second disadvantage.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an automatic telescopic drainage tube for overcoming the defects of the prior art.

The purpose of the utility model can be realized through the following technical scheme:

the utility model provides a drainage tube that can stretch out and draw back automatically, is including first shell and the second shell that can dismantle the connection to and the rotating assembly who sets up on the second shell, be provided with the spiral spring leaf in the rotating assembly, the winding of rotating assembly outer wall has the drainage tube main part.

Furthermore, a hollow column for placing the rotating component is fixed on the second shell, and the spiral spring piece is fixed on the hollow column.

Further, the rotating assembly comprises a rotating disk, a round hole arranged in the middle of the rotating disk and used for being connected with the second shell, and an isolation column fixed on the inner wall of the rotating disk.

Furthermore, two clamping grooves for drawing out the drainage tube main body are formed in the edge of the rotating disc, the drainage tube main body is placed between the isolation column and the inner wall of the rotating disc, and two ends of the drainage tube main body penetrate through the clamping grooves and are wound on the outer wall of the rotating disc in the same direction, so that the drainage tube is prevented from being separated from the rotating disc in the drawing process.

Furthermore, the drainage tube main body is regularly wound into two layers.

Further, the first housing and the second housing are connected by screws.

Furthermore, fixing clamps for fixing the drainage tube main body are arranged at two ends of the drainage tube main body, so that the drainage tube main body can be conveniently fixed on clothes.

Furthermore, a spring wire is arranged inside the tube wall of the drainage tube main body and is arranged in a winding manner, so that the drainage tube main body is prevented from being flattened, and an internal supporting effect is achieved.

When the drainage tube is used, by pulling two ends of the drainage tube body, force is transmitted through the drainage tube body, so that the rotating assembly rotates around the hollow column, and stress is concentrated on the spiral spring pieces. After the traction is stopped, the stress of the spiral spring piece is released, so that the rotating component rotates reversely, and the drainage tube body is automatically wound on the rotating component again.

Compared with the prior art, the utility model discloses in the actual work, if careless tractive drainage tube main part, can make the automatic flexible of drainage tube main part to concentrate the stress of tractive on the coil spring piece, rather than direct action on the fixed suture of skin, thereby avoid droing drainage tube main part tractive.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Examples

An automatic telescopic drainage tube, as shown in figure 1, comprises a first shell 1 (figure 4) and a second shell 2 (figure 5) which are detachably connected, and a rotating component arranged on the second shell 2, wherein a spiral spring sheet 6 is arranged in the rotating component, and a drainage tube main body 8 is wound on the outer wall of the rotating component. The second shell 2 is fixed with a hollow column 7 for placing the rotating component, and the spiral spring piece 6 is fixed on the hollow column 7. The rotating assembly comprises a rotating disk 3, a round hole 4 arranged in the middle of the rotating disk 3 and used for connecting the second shell 2, and an isolation column 5 fixed on the inner wall of the rotating disk 3. As shown in fig. 7, two clamping grooves for pulling out the drainage tube main body 8 are arranged on the edge of the rotating disc 3, the drainage tube main body 8 is placed between the isolation column 5 and the inner wall of the rotating disc 3, and two ends of the drainage tube main body respectively penetrate through the clamping grooves and are wound on the outer wall of the rotating disc 3 in the same direction. The drainage tube body 8 is orderly wound into two layers.

The first housing 1 and the second housing 2 are connected by screws. The two ends of the drainage tube main body 8 are provided with fixing clamps 9 for fixing the drainage tube main body 8, so that the drainage tube main body 8 can be conveniently fixed on clothes. As shown in FIGS. 8-9, the wall of the drainage tube body 8 is provided with the spring wire 10, and the spring wire 10 is wound in the wall of the drainage tube body, so as to prevent the drainage tube body 8 from being flattened and play a role of internal support.
