[0002] Pleural and abdominal effusion are common diseases. After pleural and abdominal effusion, the effusion in the pleural or abdominal cavity needs to be drained in time. Traditional drainage methods generally include two methods: one is that medical staff draws out through a syringe or the other uses an existing thoracentesis bag.

[0003] In the syringe extraction method, during the extraction process, if there is too much liquid in the syringe, the needle needs to be separated from the syringe body, with the needle remaining on the patient's body. After the liquid in the syringe is discharged, it is connected to the needle remaining on the body to continue extraction. Such an operation will cause very bad discomfort to the patient.

[0004] When using the existing thoracentesis kit, the thoracentesis kit has the following clinical pain points:

[0005] (1) It requires surgical incision and the use of anesthesia, which is obviously invasive for the removal of pleural and abdominal fluid;

[0006] (2) Two professional and skilled doctors are required to perform the operation simultaneously;

[0007] (3) The procedure for removing pleural and ascites fluid is repetitive, cumbersome, and time-consuming;

[0008] (4) Improper operation may lead to medical accidents;

[0009] (5) Low patient compliance;

[0010] (6) High cost, including the cost of disposable thoracentesis materials, surgery, anesthesia, etc. Utility Model Content

[0031] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0032] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] As described in the background technology, the traditional simplest and most convenient method of draining liquid is for medical personnel to draw it out through a syringe. During the withdrawal process, if there is too much liquid in the syringe, the needle needs to be separated from the syringe body, with the needle remaining on the patient's body. After the liquid in the syringe is drained, it is connected to the needle remaining on the body to continue draining. Such an operation will cause very bad discomfort to the patient.

[0034] Based on the above reasons, this embodiment provides a thoracoabdominal puncture kit, such as Figure 1 and Figure 2 As shown, the chest and abdominal puncture kit includes a puncture needle 100, a drainage tube 300 and a drainage bag 400. One end of the drainage tube 300 is connected to the puncture needle 100, and the other end is connected to the drainage bag 400.

[0035] With the above technical features, medical personnel can quickly and conveniently complete chest or abdominal puncture and drain out the accumulated fluid. Compared with traditional syringe extraction, it is more comfortable and cheaper and more practical than existing puncture kits. When in use, medical personnel connect the puncture needle and the drainage bag together through the drainage tube, and then puncture the puncture needle into the chest or abdominal cavity. The accumulated fluid will flow from the puncture needle through the drainage tube into the drainage bag. When the height of the drainage bag is lower than the puncture needle, the accumulated fluid in the chest or abdominal cavity will automatically flow into the drainage bag, thereby realizing the drainage of the chest or abdominal cavity. After the accumulated fluid in the drainage bag reaches a certain amount, the accumulated fluid in the drainage bag can be discharged.

[0036] like Figure 2 and Figure 5 As shown, in order to facilitate replacement of the drainage bag or stop flow in the drainage tube, in some embodiments, a flow stopper 500 is installed on the drainage tube 300; the flow stopper 500 can also be other components with the same function as the flow stopper, such as a valve.

[0037] In order to avoid or reduce the impact of the movement of the drainage tube on the puncture needle, in some embodiments, the puncture needle 100 is connected to the drainage tube 300 through a hose 200; the hose 200 uses a rubber sleeve or other soft components to ensure the connection is sealed while also making the connection between the puncture needle and the drainage tube soft, thereby reducing the discomfort caused to the patient by the movement of the puncture needle caused by the movement of the drainage tube.

[0038] In order to facilitate medical personnel to take the puncture needle and insert the puncture needle into the chest cavity and / or abdominal cavity, in some embodiments, the puncture needle 100 is provided with a gripping portion 101, which can also serve as a connection, facilitating connection with the hose. The gripping portion and the puncture needle are a whole and have a channel connected to the needle hole of the puncture needle.

[0039] In order to facilitate medical personnel to add liquids such as saline to the chest cavity or abdominal cavity through the same puncture needle, because when treating the chest cavity and abdominal cavity, it may be necessary to add saline for flushing, therefore, in some embodiments, such as Figure 3 and Figure 7 As shown, the handle 101 is provided with a flushing tube 102, which is connected to the puncture needle. A blocking block is installed at the end of the flushing tube 102. When draining effusion, medical personnel close the outlet of the flushing tube with the blocking block, allowing the effusion to enter the drainage tube only through the puncture needle and then drain into the drainage bag through the drainage tube. When flushing the chest or abdominal cavity, medical personnel remove the blocking block and add a liquid such as physiological saline through the flushing tube. The liquid enters the abdominal or chest cavity through the puncture needle. After filling, the blocking block is closed. The flushed liquid or effusion is then discharged from the puncture needle. The blocking block can be a rubber cap or other component that can perform the same function, such as a stop valve.

[0040] The above-mentioned convenience is also achieved by injecting liquids such as physiological saline into the chest cavity or abdominal cavity. In one embodiment, Figure 4 As shown, the puncture needle 100 includes a liquid inlet channel 103 and a liquid outlet channel 104. The liquid outlet channel 104 is connected to the drainage tube 300, and the liquid inlet channel 104 is connected to the flushing tube 102 provided on the gripping portion. A block is installed at the end of the flushing tube 102. When the medical staff is draining the accumulated fluid, the flushing tube closes the outlet through the block, and the accumulated fluid can only be discharged from the liquid outlet channel and enter the drainage bag through the drainage tube; when flushing the chest or abdominal cavity, the medical staff removes the block, adds liquid such as physiological saline through the liquid inlet channel, and the flushed liquid or accumulated fluid is then discharged from the liquid outlet channel; the block can be a rubber cap or other components that can play the same role, such as a stop valve.

[0041] In order to facilitate medical staff or the patient's family to handle the accumulated fluid in the drainage bag, because the patient's family or medical staff may need to release the accumulated fluid in the drainage bag to avoid the patient feeling uncomfortable due to excessive weight of the accumulated fluid, or the medical staff may need to sample the accumulated fluid in the drainage bag; therefore, in some embodiments, Figure 6 As shown, the drainage bag has a drainage tube 402 with a valve 401 below it, and the bag is equipped with a liquid level marking. The drainage tube with a valve (or other components with the same function) allows medical staff or family members to drain the accumulated fluid in the drainage bag; the liquid level marking allows medical staff or family members to record the amount of fluid discharged. A hanging rope 403 is also provided at the top of the drainage bag for convenient placement and hanging.

[0042] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
