Description

Technical Field

[0001] The utility model relates to the technical field of abdominal water drainage, in particular to an ascites extraction device. Background Art

[0002] Ascites refers to the excessive accumulation of free fluid in the abdominal cavity. Under any pathological conditions, an increase in the amount of fluid in the abdominal cavity exceeding 200 ml is called ascites. When the patient's abdominal water accumulation is severe, the patient will have symptoms of difficulty breathing and difficulty eating. The most direct treatment is to extract and drain the ascites. Before extraction, the doctor needs to use a syringe to draw a tube of sample for testing. After testing, formal extraction can be performed. When the doctor uses a syringe for puncture, the needle is thin and the force is unstable, and it is easy to tilt during puncture. At the same time, during drainage, the drainage needle is not convenient to fix, and the drainage line is easily pulled when it is accidentally touched.

[0003] In summary, the utility model solves the existing problems by designing an ascites extraction device. Utility Model Content

[0023] An ascites extraction device comprises a fixing patch 1, an interface tube 2 is installed at the center of the outer side surface of the fixing patch 1, an outer thread 201 is provided at one end of the outer ring surface of the interface tube 2, an inner thread 202 is provided on the inner wall of the interface tube 2, a positioning column 3 is installed inside the interface tube 2, a needle hole 301 is provided at the center of one end of the positioning column 3, a puncture needle 4 is installed inside the needle hole 301, one end of the puncture needle 4 is connected to a connector 5, one end of the connector 5 is connected to a drainage tube 6, and an arc-shaped groove 601 is provided at one end of the outer ring surface of the drainage tube 6.

[0024] For example, please refer to Figure 1 , Figure 2 and Figure 3 The inner side of the interface tube 2 is provided with a step plate, and a through hole is opened at the center of the step plate to communicate with the other side of the fixing patch 1. The outer ring surface of one end of the positioning column 3 is provided with a thread, and one end of the positioning column 3 is threadedly connected to the inner thread 202 of the inner side of the interface tube 2. The outer size of the positioning column 3 matches the inner side size of the interface tube 2. After the positioning column 3 is installed on the inner side of the interface tube 2, there will be no gap and shaking. The needle hole 301 runs through both ends of the positioning column 3, and the inner side size of the needle hole 301 matches the size of the puncture needle 4 and the syringe needle used for sampling. When ascites is extracted from a patient with abdominal effusion, first, one end of the positioning column 3 is tightened and connected to the inner thread 202 of the inner side of the interface tube 2, and then the syringe needle used for sampling is inserted and penetrated through the needle hole 301 to pierce the patient's skin. In this process, under the action of the positioning column 3, the needle can pierce the skin straightly, which is convenient for the doctor to apply force and effectively prevents the needle from tilting during puncture.

[0025] For example, please refer to Figure 1 , Figure 2 and Figure 3 The inner side surface of one end of the connector 5 is provided with a thread, and the connector 5 can be sleeved on the outer ring surface of the interface tube 2 and threadedly connected with the external thread 201 after the positioning column 3 is removed. One end of the drainage tube 6 is connected to the storage container, and the other end of the drainage tube 6 is connected to the puncture needle 4. The arc groove 601 on the drainage tube 6 is clamped with one end of the connector 5, and the connector 5 can rotate freely inside the arc groove 601. When the sample extraction and testing are completed and the ascites is prepared to be formally extracted, the positioning column 3 is first removed from the interface tube 2, and then the puncture needle 4 on the connector 5 is aligned with the puncture hole during sampling and inserted into the patient's body, and gradually inserted inwardly. Finally, the connector 5 and the interface tube 2 are threadedly connected. At this time, the puncture needle 4 is limited and fixed by the connector 5, which can effectively prevent the puncture needle 4 from generating a pulling force after the drainage tube 6 is accidentally touched.

[0026] Working process of the utility model: using an ascites extraction device designed in this scheme, when extracting ascites from a patient with abdominal effusion, first tighten one end of the positioning column 3 with the inner thread 202 on the inner side of the interface tube 2, and then insert the sampling syringe needle into the patient's skin through the needle hole 301. During this process, under the action of the positioning column 3, the needle can puncture the skin straightly, which is convenient for the doctor to apply force and effectively prevents the needle from tilting during puncture. When the sample extraction and testing are completed and the ascites is ready to be formally extracted, first remove the positioning column 3 from the interface tube 2, and then insert the puncture needle 4 on the connecting head 5 into the patient's body in alignment with the puncture hole during sampling, and gradually insert it inwards. Finally, the connecting head 5 and the interface tube 2 are threadedly connected. At this time, the puncture needle 4 is limited and fixed by the connecting head 5, which can effectively prevent the puncture needle 4 from generating a pulling force after being accidentally touched by the drainage tube 6.
