Drawings
The invention will be further described with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
Fig. 1 is a schematic structural diagram of the present invention, as shown in the figure, the thoracic puncture drainage suction device in this embodiment includes a puncture needle 1, an elastic drainage tube 2 and a catheter base 3 having a hollow cavity and communicating with the elastic drainage tube 2 to form a flow guide channel, the catheter base 3 is provided with an elastic sealing blind end, the puncture needle 1 penetrates through the elastic sealing blind end and the flow guide channel and can reciprocate and alternate along the flow guide channel, the puncture needle 1 is attached to the inner wall of the elastic drainage tube 2, and the catheter base 3 is provided with a drainage interface 6; when the puncture needle is used, the puncture part of the puncture needle 1 is pushed out of the tube end of the elastic drainage tube 2 to puncture the lung, the puncture needle 1 returns to the hollow cavity 31 of the catheter seat 3 along the elastic drainage tube 2 after puncture is completed, the elastic drainage tube 2 enters the thoracic cavity along with the puncture needle 1 and stays in the lung cavity to be used as a suction channel of gas and liquid in the lung cavity, then the suction device is communicated with the liquid drainage interface 6 to perform air suction and liquid drainage treatment, and effusion or gas in the lung cavity enters the hollow cavity 31 of the catheter seat 3 through the elastic drainage tube 2 and is discharged through the liquid drainage interface 6. Since the puncture needle 1 is retracted into the hollow cavity 31 of the catheter hub 3, the progress of aspiration and liquid extraction is not affected. The elastic sealing blind end of the catheter seat 3 enables the catheter seat 3 and the elastic drainage tube 2 to form a one-way communication channel, although the puncture end of the puncture needle 1 penetrates through the elastic sealing blind end and extends out of the port of the elastic drainage tube 2, the puncture needle 1 and the elastic sealing blind end belong to a sealing fit state, namely, the puncture needle 1 and the elastic sealing blind end belong to a zero-clearance sealing fit state, and the puncture needle 1 can be inserted in the elastic sealing blind end back and forth without affecting the air tightness. Because the hydrops in lung chamber is accumulated along with time, consequently need carry out the pump drainage many times, and use the pump drainage device of this embodiment can not keep somewhere drainage elastic catheter in the lung chamber, because the flexibility of drainage elastic catheter can not injure lung chamber tissue, realize the effect of a puncture pump drainage many times, alleviate patient's misery, reduce the operating procedure simultaneously.
In the embodiment, the surface of the puncture needle 1 is provided with a groove 4; because the puncture needle 1 is attached to the inner wall of the elastic drainage tube 2, the groove 4 is arranged to facilitate the exhaust when the puncture needle 1 is pushed in the re-puncture process, and the smooth puncture is ensured. The puncture needle 1 is a common medical needle and is provided with an inner hole channel, and the groove 4 is communicated with the inner hole channel of the puncture needle 1.
In this embodiment, the groove 4 is arranged on the puncture needle 1 corresponding to the elastic drainage tube 2; the groove 4 is mainly used for exhausting air in the puncture process, the puncture needle 1 is attached to the inner wall of the elastic drainage tube 2, and therefore only the groove 4 is formed in the surface of the puncture needle 1 corresponding to the elastic drainage tube 2, and the groove 4 is communicated with an inner hole channel of the puncture needle 1 to play a good role in exhausting air, and the push of the puncture needle 1 cannot be influenced.
In the embodiment, the hollow cavity 31 of the catheter seat 3 is larger than the aperture of the elastic drainage tube 2; that is, in the elastic drainage tube 2, there is almost no pore between the puncture needle 1 and the elastic drainage tube 2, and since the catheter holder 3 has a certain hollow cavity 31, the hollow cavity 31 not only has a space for collecting liquid, but also after the puncture needle 1 exits from the elastic drainage tube 2, the channel structure formed by the elastic drainage tube 2 and the catheter holder 3 is more beneficial to the pumping, ensuring the pumping smoothly.
In this embodiment, the catheter hub 3 has a tapered cross-section; the suction is convenient to form negative pressure, and the suction efficiency and the suction smoothness are improved.
In this embodiment, the outside of the open end of the elastic drainage tube 2 is smaller than the outside diameter of the tube body of the elastic drainage tube 2; the outer diameter of the tube body of the elastic drainage tube 2 towards the opening end is gradually reduced; namely, the outer diameter section of the opening end of the elastic drainage tube 2 is in an arc structure with smooth transition, while the inner diameter of the elastic drainage tube 2 is unchanged, and the structure is favorable for the elastic drainage tube 2 to enter the lung cavity more smoothly along with the puncture needle 1, so that the resistance formed between the elastic drainage tube and the puncture hole is reduced, and the discomfort of a patient is reduced.
In the embodiment, the inner diameter of the elastic drainage tube 2 is 1-1.5 mm; the internal diameter is small, the formed wound is small, the body feeling pain is small, the puncture can be carried out without using anesthetic, and meanwhile, the smoothness of air exhaust and liquid discharge is not influenced.
In this embodiment, the puncture needle 1 is provided with a needle holding handle 5; facilitating the pushing in the puncture and the withdrawal after the puncture.
In this embodiment, the elastic drainage tube 2 is a silicone tube or a PVC tube.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
