For purposes of clarity, not every component may be labeled in every drawing. Embodiments of various aspects of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:
fig. 1 is a schematic structural view of the anti-drop closed thoracic drainage tube of the present invention;
fig. 2 is a schematic cross-sectional structure view of the inner tube according to the present invention.
Detailed Description
For a better understanding of the technical aspects of the present invention, specific embodiments are described below in conjunction with the appended drawings.
As shown in the figure 1, the utility model provides an anti-drop thoracic cavity closed drainage tube, which mainly comprises an inner tube 1 and a sleeve 2. The inner tube 1 is a PVC tube, a drainage hole 12 is arranged at the first end (the insertion end 11) of the inner tube and is used for penetrating through a perforation of the thoracoabdominal part to enter the thoracic cavity and leading out effusion in the thoracic cavity, and the other end (the connection section 13) is an open end and is used for connecting a liquid collection bag or a liquid collection tank.
Alternatively, the end of the insertion end 11 is spherical or has an arc surface, and the drainage holes 12 are provided in the side wall portion, and may be one or more, generally elliptical or circular holes.
Therefore, the effusion in the thoracic cavity can enter the inner tube 1 through the drainage holes 12 and flow to the liquid collecting bag or the liquid collecting tank along the inner tube 1.
Furthermore, because the depth of the inner tube 1 extending into the thoracic cavity is related to the position of accumulated liquid, the outer wall of the inner tube 1 is sleeved with the sleeve 2, the first end of the sleeve 2 is provided with the pressing cap 3, the second end of the sleeve 2 is provided with the air bag 21, and the first end of the sleeve 2 further extends out of the one-way valve 23 connected to the air bag 21 for injecting gas or liquid into the air bag 21.
Specifically, the pressing cap 3 is provided to be screwed with the sleeve 2, and when the pressing cap 3 is tightened, the sleeve 2 and the inner pipe 1 are relatively fixed.
In a specific embodiment, the inner tube 1 is inserted and controlled to a suitable depth, for example, a depth of 12cm, then the sleeve 2 is slid to a suitable position to allow the balloon 21 to enter the thoracic cavity, then the pressing cap 3 is screwed down to fix the sleeve 2 and the inner tube 1, and then the syringe is connected to the one-way valve 23 to inject the physiological saline into the balloon 21 to expand the balloon 21, so as to fix the sleeve 2 and prevent the drainage tube from being pulled out.
Further, in the above embodiment, as shown in fig. 2, the first end of the sleeve 2 has a plurality of pressing sheets 24 distributed in a central symmetry manner, and the outer wall of the pressing sheet 24 is provided with a screw thread capable of being in threaded connection with the pressing cap 3.
And the diameter of the first end of the pressing cap 3 is smaller than that of the second end, so that when the pressing cap 3 is screwed on the pressing sheet 24, the pressing sheet 24 is centripetally closed to press the inner tube 1, so that the sleeve 2 and the inner tube 1 are kept relatively fixed.
Further, in order to facilitate control of the position of the balloon 21, the length of the sleeve 2 is greater than 5 cm. Preferably, the outer wall of the sleeve 2 is provided with scale marks, and the position of the air bag 21 can be judged according to the scale marks.
In the above-described embodiment, the balloon 21 is fixedly connected to the cannula 2, and optionally, the balloon comprises a rubber balloon or a latex balloon.
Further, as shown in fig. 2, a groove 13 is formed on the inner tube 1, the air bag 21 and the check valve 23 are connected through an air pipe 22, and the air 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.
Thus, the outer contour of the cannula 2 can be kept round, the insertion into the thoracic cavity is facilitated,
in other embodiments, the communication between the balloon 21 and the one-way valve 23 may also be achieved by means of a sandwich arranged within the sleeve 2.
In combination with the above embodiment, the utility model discloses a setting can make the gasbag on the sleeve pipe also take place to remove for the gliding sleeve pipe of inner tube, just so can make the relative position of gasbag and inner tube change, promptly, can enter into different depths according to the position of pleural effusion, the tip of control drainage tube to, can keep this kind of depth through the gasbag, need not use sticky tape etc. to fix, and be difficult to drop, especially the adjustment depth that can also be free again, convenient to use.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to be limited thereto. The present invention is well known in the art and can be modified and decorated without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention is subject to the claims.
