Example 1

This embodiment 1 provides a nasobiliary tube with a buffering structure, as shown in fig. 1-2, comprising a nasobiliary tube including a nasal cavity portion 1, an inner cavity portion 2, and an external drainage portion 3; the nasal cavity part 1 is provided with a buffer bag 4 for preventing the nasobiliary duct from pressing the surface mucosa, and the buffer bag 4 is provided with an inner cavity for filling water.

The principle of the device is as follows: the nose bile duct is a flexible straight tube, a buffer bag 4 is arranged on the nasal cavity part 1, and the buffer bag 4 is fixedly arranged from the nasal cavity part 1 to the inner cavity part 2 on the nose bile duct. Insert the nasal cavity with the nose bile duct earlier, accomplish and insert the back, fill water with cushion bag 4 again, whole cushion bag 4 is bloated, contact skin layer, the nose bile duct is wrapped up in the inside of cushion bag 4 to guarantee that the nasal cavity part 1 of nose bile duct can not the direct contact skin to inner chamber part 2, and liquid has certain mobility, can not directly press the top layer mucosa at the nose bile duct, thereby prevent to cause the pressure nature damage of top layer mucosa.

In the embodiment, the buffer bag 4 is fixedly attached to the nasal cavity portion 1 to the inner cavity portion 2, and the buffer bag 4 is of a thin-wall flexible structure. The cushion bag 4 is in direct contact with the skin and is used for holding water, so the bag wall needs to be thin and has a malleable structure, and the pressure loss of the skin can be prevented.

In this embodiment, the buffer bag 4 is provided with a water filling opening at the junction of the nasal cavity portion 1 and the external drainage portion 3, the water filling opening being provided with a sealing structure. The water filling structure is used for filling water or discharging water, and the water filling action is carried out after the whole nasal bile duct is inserted, and the water discharging action is carried out before the nasal bile duct is drawn out. The water filling opening is positioned at the joint of the nasal cavity part 1 and the external drainage part 3, which is beneficial to convenient water filling and water prevention.

In this embodiment, the cushion pouch 4 is an annular column having a cavity for receiving the nasal portion 1 through the inner portion 2, the side wall of the column having a water-filled space in two layers. The annular column structure can be perfectly attached to the whole nasal bile duct.

In this embodiment, the two ends of the annular column are connecting parts 402, a buffer part 401 is arranged between the two connecting parts 402, and the diameter of the buffer part 401 is smaller than that of the connecting part 402. The diameter of buffer 401 is littleer, and the degree of compressing tightly at both ends is greater than the centre after filling water, further guarantees the stability of connecting.

In the present embodiment, the connecting portion 402 gradually decreases in diameter from a position connected to the cushioning portion 401 to a position at an end of the connecting portion 402. The connecting part 402 gradually reduces the diameter from the position connected with the buffer part 401 to the end part of the connecting part 402, so that an arc buffer surface is formed after water is filled, and the pressure loss is further reduced when the connecting part is in contact with the skin.

In this embodiment, the water filling space inside the side wall between the both ends of the buffer bag 4 is uniformly provided. The uniform arrangement means that the size of the water filling space inside the side wall is uniformly arranged, so that the uniform buffering and bearing capacity can be ensured. It should be noted that the uniform arrangement does not mean that the entire space is uniform in size, but means that the inner space is arranged according to a certain rule, including the later mentioned wave-shaped or other uniform and regular smooth structure.

In the present embodiment, the connection between the buffer portion 401 and the connection portion 402 is a buffer connection. Further reducing the pressure loss to the skin. The smooth structure is better with the contact of skin, comfort level when can increase the use, better reduction skin pressure loss guarantees buffering effect.

In this embodiment, the outside of the side wall of the buffer bag 4 is waved after being filled with water. The outside position means that the one side of keeping away from the nose bile duct after installing on the nose bile duct is the outside, and the great performance that guarantees cushioning effect is taken into account to the wave is also littleer in the possibility that slides away when accomplishing the buffering to can play the effect of fixed nose bile duct.

In this embodiment, the end of the buffer bag 4 close to the outer drainage portion 3 has a fixing ring 403 for fastening the buffer bag 4. The fixing ring 403 is used to further ensure that the position of the buffer bag 4 does not slip. And the fixing ring 403 is located at one end of the drainage portion without burden of skin compression.

In the present embodiment, it should be noted that the buffer bag 4 is recommended to be filled with physiological saline, and the amount of water filled is not too much, so as to ensure that the bent part of the bendable straight tube has a buffer accommodating position after being filled with water; when needing to take out the nose bile duct, directly stab buffering bag 4 and let the water of the inside directly flow out, perhaps will seal and open, the water of the inside flows out from sealing promptly, and buffering bag 4 pastes tight nose bile duct once more, when guaranteeing to take out the nose bile duct, and buffering bag 4 can not exert an influence to the removal of nose bile duct.

It should be explained that: the normal saline is generally used for filling water, so that the health and the comfort of a human body cannot be influenced. In addition, when the nasal bile duct is used, the use mode is the same as that of a common nasal bile duct, and the difference is that after the nasal bile duct is inserted, water is flushed into the buffer bag 4 to form a buffer part 401; and the outer layer of the buffer bag 4 is preferably made of an imitation leather thin wall, so that the comfort level of a patient is mainly improved, and the purpose of buffering and pressure reduction can be fully achieved after the thin wall is filled with water.

To be explained with respect to the figures: for convenience of illustration, the nose bile duct is drawn as a straight tube, but the conventional nose bile duct is a bendable straight tube and is bent according to the structure of a human body after being placed.

The above-mentioned embodiments, objects, technical solutions and advantages of the present invention are further described in detail, it should be understood that the above-mentioned embodiments are only examples of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
