Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

Example 1

This example 1 provides an ultrasonic imaging dual-lumen closed thoracic drain, and the examples described below with reference to the drawings are exemplary only for the purpose of illustrating the present invention and are not to be construed as limiting the present invention. Referring to fig. 1 and 2, the ultrasonically-visualized dual-chamber closed thoracic drainage tube includes:

an outer case 10, the outer case 10 being divided into two parts of a gas chamber 11 and a liquid chamber 12 by a partition plate 20, the partition plate 20 being connected to a distal end portion of the outer case 10 such that one end of the gas chamber 11 is a dead end and the other end is a gas port 110; the liquid chamber 12 is open at both ends, and the liquid port 120 is located at the proximal end of the outer shell 10; the separation plate may be broken at least at the blind end so as to be drawn out from the gas port 110.

The gas in the gas cavity 11 can be obviously subjected to ultrasonic imaging, so that the embodiment of the invention realizes the accurate positioning of the position of the drainage tube and the correct placement of the position of the drainage tube.

When pleural effusion can not be drained continuously, the air cavity 11 can be filled with air, the purpose of ultrasonic development is achieved, the position of the catheter is accurately positioned, and clinical decision is quickly obtained.

Further, the whole partition plate 20 can be taken out integrally through the drawing gas port 110, and simultaneously carries the blockage to move even directly to the outside of the pipe, so that the purposes of clearing the blockage and communicating the pipe are achieved.

Example 2

This embodiment 2 may be further improved on the basis of embodiment 1, and the description thereof will be omitted for the same or similar parts. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention. Specifically, referring to fig. 1 to 4, the present embodiment includes:

the outer shell 10 and the partition plate 20 are both made of elastic materials. For example, a rubber material may be selected, or Polyamide (PA), thermoplastic elastomer (TPE), Polyurethane (PU), polyvinyl chloride (PVC), and Polyolefin (PE) Polyetheretherketone (PEEK), among others.

In this embodiment, the thickness of the divider panel 20 at the blind end and at the divider panel edge is thinner than the rest of the divider panel, and the divider panel edge portion is connected to the outer shell. The partition plate is thereby broken off at the blind end and at the edge when pulled out. Accordingly, the partition plate 20 is also easily broken at the edge junction of the gas ports 110.

Further, the divider plate 20 may be blind and have a thin and soft edge portion and a hard edge portion to facilitate snapping.

The thickness of the outer case 10 may be thicker than the partition plate.

In contrast, the liquid port 120 is larger, and the gas port 110 is smaller, so that after the partition plate 20 is drawn out, since the liquid port 120 can be externally connected with a drainage device, the gas port can be closed by means of pressure and elasticity of the drainage tube itself when drainage is performed.

Since the partition plate 20 is elastic, the volume ratio of the gas chamber 11 and the liquid chamber 12 is variable. For example, under normal conditions, the volumes of the two chambers may be the same or almost the same, or of course, the volumes may be in other proportions, and then when the gas chamber is pumped, the volume of the gas chamber naturally decreases until the gas chamber is completely pumped (which may be considered as a completely pumped state when reaching a certain pressure according to actual needs), the gas chamber 11 is hardly visible, and the liquid chamber 12 occupies most of the space.

The cross section of the outer shell 10 is circular, square or triangular. In addition, other shapes can be arranged according to actual needs.

In this embodiment, when the partition plate 20 is withdrawn, the gas chamber 11 is almost disappeared, leaving only the liquid chamber 12, and the gas port 110 can be closed by the outer case 10.

Example 3

This embodiment 3 may be further implemented on the basis of embodiment 1 or embodiment 2, and may not be limited to the ultrasound imaging dual-lumen closed thoracic drainage tube described in the present invention. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention. Specifically, referring to fig. 1 to 6, the present embodiment includes:

a method for using a double-cavity closed thoracic drainage tube for ultrasonic imaging comprises the following steps:

step S10, filling gas from the gas port 110, and filling the gas cavity 11 with gas; for example, the air can be filled with air by using a syringe and then the air can be checked for leakage, and the air can be used under the condition that air does not leak so as to avoid adverse effects on patients during air leakage.

Step S20, placing the far end of the double-cavity thoracic closed drainage tube which is subjected to ultrasonic imaging in a focus, and placing the near end outside the body; as the gas cavity 11 is filled with gas, the gas can be obviously imaged by ultrasonic, so that the position of the drainage tube can be accurately positioned in real time, the drainage tube can be rapidly and accurately placed, the operation time is shortened, and the pain of a patient is reduced.

Step S30, pumping from the gas port 110 to evacuation; since the drainage tube is already in place, the liquid cavity 12 needs to be enlarged in volume for drainage, and the gas cavity is prevented from being leaked, so that the gas is evacuated to seal the gas cavity 11.

Step S40, draining;

step S50, when the effusion can not be drained continuously, firstly, the gas port 110 is inflated again, the position of the double-cavity closed thoracic drainage tube for ultrasonic imaging is judged, if the position is abnormal, the original position is recovered, and the gas port 110 is pumped to be evacuated; because gas chamber 11 is evacuated to find time, consequently, the drainage tube position is difficult for detecting this moment, when appearing the pleural effusion and can not be by the condition of continuation drainage, can aerify gas chamber 11 once more, at first judge whether the drainage tube shifts, if the position change, then can adjust the correct position for the hydrops continues to be drained, and it can to bleed again this moment.

Step S60, if the drainage is not continued after the original position is recovered, indicating that the liquid chamber is blocked, the separation plate 20 is drawn out from the gas port 110, and the blockage 30 (usually fibrin and cells, etc.) on the tube wall loosens and moves towards the gas port along with the drawing of the separation plate 20; the blockage is extracted from the liquid port 120, for example, the blockage can be extracted by an injector or the like, so that the normal work of the drainage tube is realized.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
