Detailed ways

In order to better understand the technical content of the present invention, specific embodiments are given and described in conjunction with the accompanying drawings as follows.

With reference to FIG. 1 , the present utility model proposes an anti-shedding chest cavity closed drainage tube, which mainly includes an inner tube 1 and a sleeve 2 . The inner tube 1 is a PVC tube, and its first end (insertion end 11) is provided with a drainage hole 12, which is used to enter the chest cavity through the perforation of the chest and abdomen, and lead out the effusion in the chest cavity, and the other end (connecting section 13) Is the open end for connecting a collection bag or a collection tank.

Optionally, the end portion of the insertion end 11 is spherical or has an arc surface, and the drainage hole 12 is provided on the side wall portion, which may be one or more, and is generally an oval or circular hole.

In this way, the effusion in the pleural cavity can enter the inner tube 1 through the drainage hole 12 and flow to the collection bag or the collection tank along the inner tube 1 .

Further, since the depth that the inner tube 1 penetrates into the thoracic cavity is related to the position of the effusion, a sleeve 2 is sleeved on the outer wall of the inner tube 1, the first end of the sleeve 2 is provided with a pressure cap 3, and the second end is There is an air bag 21 , and a one-way valve 23 connected to the air bag 21 is extended from the first end of the sleeve 2 , for injecting gas or liquid into the air bag 21 .

Specifically, the pressure cap 3 is configured to be threadedly connected with the sleeve 2, and when the pressure cap 3 is tightened, the sleeve 2 and the inner tube 1 are relatively fixed.

In a specific embodiment, the inner tube 1 is inserted, and the inner tube 1 is controlled to be at a suitable depth, such as a depth of 12 cm, and then the cannula 2 is slid to a suitable position, so that the balloon 21 just enters the thoracic cavity, and then tighten the pressure Cap 3, fix the cannula 2 and the inner tube 1, then use a syringe to connect the one-way valve 23, inject physiological saline into the airbag 21, inflate the airbag 21, and fix the cannula 2 to prevent the drainage tube from coming out.

Further, in the above embodiment, as shown in FIG. 2 , the first end of the sleeve 2 has a plurality of pressing pieces 24 distributed symmetrically in the center, and the outer wall of the pressing pieces 24 is provided with threads, which can be threaded with the pressing cap 3 connect.

And the diameter of the first end of the pressure cap 3 is smaller than the diameter of the second end. In this way, when the pressure cap 3 is tightened on the pressing piece 24, the pressing piece 24 is moved toward the center, and the inner tube 1 is compressed, so that the sleeve 2 and the inner tube are 1 remains relatively fixed.

Further, in order to facilitate the control of the position of the airbag 21, the length of the sleeve 2 is greater than 5 cm. Preferably, a scale line is provided on the outer wall of the sleeve 2, and the position of the airbag 21 can be determined according to the scale line.

In the above-mentioned embodiment, the airbag 21 is fixedly connected with the sleeve 2, and optionally, the airbag includes a rubber airbag or a latex airbag.

Further, as shown in FIG. 2 , the inner tube 1 is provided with a groove 13 , the airbag 21 and the one-way valve 23 are connected by an air delivery pipe 22 , and the gas delivery pipe 22 is located on the inner side of the sleeve 2 and in the groove 13 . . The wall thickness of the sleeve 2 is 2-3 mm.

In this way, the roundness of the outer contour of the cannula 2 can be maintained, which is conducive to the insertion into the thoracic cavity.

In other embodiments, the communication between the airbag 21 and the one-way valve 23 may also be achieved by means of an interlayer provided in the sleeve 2 .

In combination with the above embodiments, the present invention provides a sleeve that can slide relative to the inner tube, so that the airbag on the sleeve also moves, so that the relative position of the airbag and the inner tube can be changed, that is, according to the inner tube of the thoracic cavity. The position of the effusion, control the end of the drainage tube to enter different depths, and this depth can be maintained by the air bag, no need to use tape to fix, and it is not easy to fall off, especially the depth can be adjusted freely, Easy to use.

Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Those with ordinary knowledge in the technical field of the present invention can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present utility model shall be determined by what is defined in the claims.
