Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a portable suction and puncture device. Background Art

[0002] In the prior art, the interface between the suction control valve and the suction tube is a threaded interface. The opening of the suction control valve is provided with an internal thread, and the head end of the suction tube is provided with an external thread for connection. The suction tube and the suction control valve are connected by the thread. Therefore, the conventional suction control valve can only be connected to the suction tube.

Existing puncture needles are typically connected to syringes for aspiration or directly to suction devices. This method is cumbersome, difficult for one person to operate, and the suction force and drainage volume of the aspirator cannot be controlled. Existing puncture needles have a non-threaded connector at the tip, which does not fit the threaded interface of the aspirator control valve. Utility Model Content

[0021] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "connect," "dispose," "install," "fix," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; they may refer to direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0023] The utility model provides a portable suction and puncture device, comprising an aspirator control valve, a suction tube, and a puncture needle. The aspirator control valve is provided with a first connecting port, a first clamping portion is provided in the first connecting port, and the head ends of the aspirator tube and the puncture needle are both provided with a second clamping portion. The aspirator tube or the puncture needle is inserted into the first connecting port and is engaged with the first clamping portion through the second clamping portion, thereby realizing the connection between the aspirator control valve and the aspirator tube or the puncture needle.

[0024] Example 1

[0025] like Figure 1 、 2As shown, this embodiment discloses a portable suction and puncture device, comprising an aspirator control valve 100, a suction tube 200, and a puncture needle 300. The aspirator control valve 100 has a first connection port 110 for connecting to the aspirator tube 200 or the puncture needle 300. The first connection port 110 has a first engaging portion. The tips of the aspirator tube 200 and the puncture needle 300 are each provided with a second engaging portion. The aspirator tube 200 or the puncture needle 300 is inserted into the first connection port 110 and engages with the first engaging portion via the second engaging portion, thereby connecting the aspirator control valve 100 to the aspirator tube 200 or the puncture needle 300. When flushing blood from the patient's abdominal cavity is required, the aspirator tube 200 only needs to be connected to the aspirator control valve 100. When puncturing the patient, the aspirator tube 200 and the aspirator control valve 100 only need to be disconnected and the puncture needle 300 connected to the aspirator control valve 100.

[0026] In this embodiment, the first clamping portion is a boss 500 arranged on the inner wall of the first connecting port 110, and the second clamping portion is a convex ring 400 arranged on the suction tube 200 or the puncture needle 300. A flat portion 410 is provided on the convex ring 400. When the flat portion 410 is aligned with the boss 500, the convex ring 400 can be smoothly inserted into the first connecting port 110. At this time, the head ends of the suction tube 200 and the puncture needle 300 can be inserted into the first connecting port 110 of the suction control valve 100. When the convex ring 400 is located below the boss 500, the suction tube 200 or the puncture needle 300 is rotated again so that the flat portion 410 of the convex ring 400 is misaligned with the boss 500, thereby making the convex ring 400 and the boss 500 clamped.

[0027] like Figure 4 、 5 As shown, further, there are two bosses 500, and the two bosses 500 are respectively arranged on two opposite sides of the inner wall of the first connecting port 110, and two oppositely arranged flat portions 410 are provided on the convex ring 400. When the suction tube 200 or the puncture needle 300 is inserted, the two flat portions 410 are aligned with the boss 500 so that the convex ring 400 can be inserted into the first connecting port 110. When the convex ring 400 is located below the boss 500, the suction tube 200 or the puncture needle 300 is rotated 90°, so that the boss 500 and the flat portion 410 of the convex ring 400 are misaligned, thereby clamping the suction tube 200 or the puncture needle 300.

[0028] Specifically, the outer surface of the boss 500 is a plane, and the flat portion 410 is also a plane. Such a structural design enables the protruding ring 400 to be smoothly inserted into the first connecting port 110 when the flat portion 410 is aligned with the boss 500.

[0029] like Figure 3As shown, in this embodiment, the portable suction and puncture device also includes a suction unit and a water inlet pipe. The suction control valve 100 is also provided with a second connection port 120 and a third connection port 130. The second connection port 120 is connected to the water inlet pipe, and the third connection port 130 is connected to the suction unit. The suction unit is used to provide suction, and the water inlet pipe is used to provide flushing water. When it is necessary to flush the patient's abdominal cavity, the first valve of the suction control valve 100 is opened, so that the water in the water inlet pipe enters the patient's abdominal cavity along the suction tube 200 for flushing; when it is necessary to aspirate the accumulated fluid in the patient's lesion, the second valve of the suction control valve 100 is opened, and the suction generated by the suction unit will suck out the accumulated fluid.

[0030] Specifically, the suction control valve 100 is a push-type or a hand-push type. The push-type suction control valve 100 opens or closes the first valve or the second valve by pressing, and the hand-push type suction control valve 100 opens or closes the first valve or the second valve by pushing or pulling.

[0031] The portable suction and puncture device in this embodiment replaces the conventional threaded interface of the suction control valve 100 with a snap-on interface, allowing for quick connection and disconnection between the suction tube 200 and the puncture needle 300, enabling rapid switching according to surgical needs. Compared to a threaded connection, the snap-on connection significantly increases connection speed. Furthermore, it solves the problem of the puncture needle 300 being unable to connect to the suction control valve 100, thereby simplifying the operation of the puncture needle 300 and effectively controlling the suction force and drainage volume.

[0032] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, and the present invention is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and substance of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
