A puncture type flushable closed thoracic drain according to an embodiment of the present invention will be described with reference to fig. 1 and 2.
As shown in fig. 1, the puncture type flushable closed thoracic drainage tube according to the embodiment of the present invention comprises a drainage tube body 100, a flushing catheter 320 and a puncture needle 220, wherein the drainage tube body 100 is transversely arranged, the puncture needle 220 is arranged in the drainage tube body 100, the puncture needle 220 is detachably connected with the drainage tube body 100, and the needle tip of the puncture needle 220 protrudes out of the drainage tube body 100 to the right; the right part of the flushing catheter 320 is arranged in the drainage tube main body 100, and the left part of the flushing catheter 320 is arranged outside the drainage tube main body 100; the wall of the drainage tube body 100 is provided with a plurality of drainage through holes 210, and the drainage through holes 210 are arranged at the right part of the drainage tube body 100; the drainage tube body 100 is provided with a washing through hole 310, the washing through hole 310 is provided at the right portion of the drainage tube body 100, and the washing through hole 310 is communicated with the right end of the washing catheter 320.
For example, as shown in fig. 1, the drainage tube body 100 is in a transversely arranged tubular shape, the needle tip of the puncture needle 220 penetrates through the drainage tube body 100 from right to left and then penetrates out of the left end of the drainage tube body 100, and the right end of the flushing catheter 320 is arranged at the right side of the drainage through hole 210; the flushing through hole 310 is the same structure as the left end opening of the drainage tube body 100. When in use, the puncture needle 220 can be directly used to penetrate through the chest wall, the right end of the drainage tube main body 100 enters the thoracic cavity along with the puncture needle 220, the drainage through hole 210 also extends into the thoracic cavity, then the puncture needle 220 is moved out, and the catheter of the water-sealed bottle is connected with the right end of the drainage tube main body 100, namely the arrangement of the drainage tube main body 100 is completed; by arranging the irrigation catheter 320, irrigation liquid can be injected into the thoracic cavity from the right end of the drainage tube main body 100 and then flows back into the drainage tube main body 100 from the drainage through hole 210, and the catheter connected with the water-sealed bottle does not need to be repeatedly disconnected and connected, so that the use is convenient; the right end of the irrigating catheter 320 is disposed at the right side of the drainage through hole 210 so that the irrigating fluid can be smoothly injected into the thoracic cavity from the right end of the drainage tube body 100 and then flows back into the drainage tube body 100 from the drainage through hole 210, and the returned irrigating fluid is not mixed with the newly injected irrigating fluid; the irrigation catheter 320 is disposed in the catheter body 100 so that the right end of the irrigation catheter 320 extends into the thoracic cavity along with the catheter body 100.
To facilitate control of the opening or stopping of the injection of the flushing liquid, in some embodiments of the present invention, the valve 130 is provided at the left portion of the flushing catheter 320.
In some embodiments of the present invention, the outer diameter of the right end of the drainage tube body 100 decreases gradually from left to right. So that the right end of the drainage tube body 100 can be conveniently extended into the thoracic cavity along with the puncture needle 220.
In other embodiments of the present invention, a puncture cavity and a flushing cavity are arranged in the drainage tube main body 100, a separation wall is arranged between the puncture cavity and the flushing cavity, the puncture needle 220 is arranged in the puncture cavity, and the drainage through hole 210 is arranged on the cavity wall of the puncture cavity; the flushing catheter 320 is arranged in the flushing cavity, and the flushing through hole 310 is arranged on the wall of the flushing cavity. For example, as shown in fig. 2, the flushing through hole 310 and the left opening of the drainage tube body 100 are different structures, the flushing through hole 310 is formed on the upper wall of the drainage tube body 100, and the drainage through hole 210 is formed on the lower wall of the drainage tube body 100, so that the backflow flushing liquid can pass through the left opening of the drainage tube body and the drainage through hole 210, and the backflow is smoother, and meanwhile, the partition wall is arranged to completely separate the newly injected flushing liquid from the backflow flushing liquid, thereby preventing the newly injected flushing liquid from being mixed with the backflow flushing liquid.
In other embodiments of the present invention, the left end of the drainage tube body 100 is provided with a first opening, so that the puncture needle 220 can extend into the drainage tube body 100 from the first opening, the first opening is provided with the sealing cover 140, and the sealing cover 140 is detachably connected with the first opening; a drainage outlet 110 is arranged on the tube wall of the drainage tube body 100, and the drainage outlet 110 is arranged at the left part of the drainage tube body 100; a gap is arranged between the puncture needle 220 and the wall of the puncture cavity. For example, as shown in FIG. 2, the tube of the water-sealed bottle can be connected to the drainage outlet 110, and the liquid flowing back from the drainage outlet into the drainage tube body 100 can flow into the water-sealed bottle from the drainage outlet 110; when the washing liquid is injected in use, if the flow rate of the refluxed liquid is very low, the strong moss adhered to the wall of the puncture cavity possibly blocks the puncture cavity, at the moment, the sealing plug can be opened, the puncture needle 220 is extended into the drainage tube main body 100 from the first opening to dredge the puncture cavity, and the strong moss can flow out of the drainage outlet 110 along with the refluxed liquid after being separated from the wall of the puncture cavity because the flow direction of the liquid in the puncture cavity is always towards the drainage outlet 110; after the dredging is finished, the puncture needle 220 is moved out, and then the sealing plug is closed, so that the drainage tube main body 100 can continue to smoothly drain.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the foregoing and various other changes, omissions and deviations in the form and detail thereof may be made without departing from the scope of this invention.
