Depending on the size and diameter of the puncture needle and the sheath for each puncture purpose, the diameter and length of the guide tube, and the position of the fixed node and scale described later may vary.

However, in the case of a needle for ascites or pleural puncture, since the size is large and puncture is particularly difficult, the portable ultrasound device for puncture of the present invention is more suitable for ascites or pleural puncture. It is preferable to have a size (inner diameter of a guide tube described later) in which the sheath can be inserted.

1 is a schematic view showing the appearance of a portable ultrasound device for ascites or pleural puncture having a needle and a guide tube into which a sheath can be inserted according to embodiments of the present invention, and FIGS. 2a and 2b are diagrams of the present invention In embodiments, it is a cross-sectional view schematically showing the inside of the portable ultrasound device for multiple or pleural puncture of FIG. 1 .

As shown in FIGS. 1 and 2A , the portable ultrasound device 1000 for multiple or pleural puncture has an empty tubular guide tube 500 equipped with an ultrasound probe 200 at its front end. A puncture needle 100 made of, for example, a metal material and a sheath 110 covering the puncture needle 100 may be inserted into the guide tube 500 .

In one embodiment, when the puncture needle 100 or sheath 110 is inserted into the guide tube 500, the ultrasonic probe 200 preferably protrudes longer than the corresponding puncture needle 100 or sheath 110 However, the reason is that damage to the skin can be prevented while locating the puncture site.

In one embodiment, the rear side of the puncture needle 100 has an outer diameter that is thicker than that of the needle 100 but smaller than the inner diameter (inner diameter) of the guide tube 500 and is made of, for example, a plastic needle handle ( 400) are combined. Here, the puncture needle 100 and the needle handle 400 may be referred to as a needle unit.

In addition, in one embodiment, the puncture needle 100 is covered by a sheath 110 made of, for example, a biocompatible polymer. The sheath 110 also has a thicker outer diameter than the corresponding sheath 110 on the rear side, but has an outer diameter smaller than the inner diameter of the guide tube 500, and a sheath handle 410 made of, for example, a plastic material is coupled. Here, the sheath 110 and the sheath handle 410 may be referred to as a sheath unit.

In one embodiment, the sheath unit composed of the sheath handle 410 and the sheath 110 and the needle unit composed of the needle 100 and the needle handle 400 inserted therein are the front side door portion 530 of the guide tube 500 ) to enter and exit.

In one example, a hole 533 through which the front portion of the sheath 110 (the needle 100 may be located therein) is formed in the door part 530.

In addition, in one example, the front end side door portion 530 of the guide tube 500 is made of a flexible material of a predetermined thickness, such as a rubber material, and may be divided into an upper door and a lower door around the central incision line. . After the sheath unit enters and exits through the door unit 530 composed of the upper door 531 and the lower door 532, the upper door 531 and the lower door 532 are made of a flexible material, so they can be closed in their original form. .

On the other hand, as another modification, instead of being divided into an upper door 531 and a lower door 532, a door made of a flexible material may be configured in a shape that pushes in and out as a whole.

In addition, as another modification, for example, the door part 530 may be formed in a structure in which the door part 530 opens and closes automatically when a button (a button formed on one side of the guide tube) is pressed. In this case, the door part 530 must be made of a flexible material such as rubber. It is not necessary to form

In one embodiment, a guide groove 510 into which the sheath handle 410 (if the handle has wings, corresponding wings) can slide is formed on the side of the guide tube 500. The guide groove 510 is connected from the front end of the guide tube 500 to the rear side, but a guide groove is not formed on a part from the rear end of the guide tube 500 .

Meanwhile, the ultrasound device 1000 fixes the entry length of the puncture needle 100 and the sheath 110 at a predetermined position when performing puncture of ascites or pleural effusion. The needle 100 and the sheath 110 surrounding the needle 100 are It may include a fixed node 300 that passes through and does not pass through the handles 400 and 410 .

The fixing node 300 descends to a part of the inner side of the guide tube through the hole 310 connected to the inside of the guide tube, thereby preventing the handle 410 from entering further, and as a result, the needle behind the corresponding sheath handle 410 The handle 400 is also prevented from entering further.

In particular, in the case of multiple or pleural puncture, since the needle 100 is large and thick, if the force for tapping the needle 100 is not properly applied, the needle 100 may be inserted too deeply into the patient, so the aforementioned fixed node ( 300 to control the entry of the needle 100 and the sheath 110.

In one embodiment, the fixed node 300 includes an external protrusion 330 of the fixed node protruding outside the guide tube 500 and an insertion portion 310 of the fixed node inserted through a hole into the guide tube 500. includes

That is, referring back to FIG. 1 , the fixed node external protrusion 330 may indicate which part of a scale of a scale S to be described later is located. In addition, the graduations of the corresponding scale S may be indicated by numbers corresponding to the fixed position of the fixed node 300, that is, to the depth into which the puncture needle 100 and the sheath 110 are inserted. For example, as shown in FIG. 1 , the graduations of the scale S may be indicated by numbers corresponding to 1 cm, 1.5 cm, 2 cm, 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm, and 5 cm.

Accordingly, holes (1, 1.5 in FIG. 1 , 1.5 in FIG. 2, 2.5, 3, 3.5, 4, 4.5, 5 holes) are installed at least one. Accordingly, the fixed node 300 may be positioned at a previously set scale position during puncture. Accordingly, it is possible to preset a depth into which the sheath 110 or the needle 100 enters through the scale S.

In one example, the graduation of the scale (S) may correspond to the insertion depth of the needle 100 or the sheath 110 into the body, or the insertion length itself or a length obtained by adding a certain length thereto. That is, when the fixed node 300 is inserted into the number indicated by number 5 in FIG. 1, the sheath handle 410 can enter the number 5 position, so the inserted depth or insertion length of the sheath 110 is, for example, 5 cm can Likewise, when the fixed node 300 is inserted into the number indicated by number 1 in FIG. 1, the sheath handle 410 can enter the number 1 position, so the insertion depth or insertion length of the sheath 110 can be, for example, 1 cm there is.
