[0002] When there is fluid or gas in the pleural cavity, the fluid and gas need to be discharged. The existing treatment method is to use a pneumothorax needle for puncture to discharge the gas and fluid through the pneumothorax needle.
[0003] Publication No. CN217119009U discloses a combined closed chest drainage device, which has a small incision during puncture and is easy to operate. It can quickly relieve the patient's breathing difficulties and circulatory disorders after treating emergency pneumothorax.
[0004] Publication No. CN116831704A discloses a pneumothorax needle using a stop valve and a one-way valve structure, which can determine whether the pneumothorax needle is deflated and the degree of deflation.
[0005] During the treatment of pneumothorax and pleural effusion, it is necessary to sample the effusion for testing, and it is also necessary to administer medication to the pleural cavity. Both of these operations require puncture. However, the existing pneumothorax needle can only perform air and fluid drainage operations, and cannot perform medication or extract effusion specimens. Therefore, a second puncture operation is often required for the patient, which increases the patient's medical pain and the workload of medical staff. Utility Model Content
[0006] The main purpose of the present utility model is to provide a novel pleural cavity puncture component for pneumothorax and pleural effusion. The first pipe is provided with a first connector, and the first connector can be connected to the pipe of a drug syringe or a sampling container, so that it is convenient for medical staff to collect pleural effusion specimens from patients and to administer medicine into the patient's chest cavity, thereby eliminating the need for additional puncture operations, alleviating the medical pain of patients, and reducing the workload of medical staff.

DETAILED DESCRIPTION
[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0025] like Figure 1-3 As shown, a new pleural cavity puncture assembly for pneumothorax and pleural effusion includes a puncture needle assembly 1 and a first pipe 3. The first pipe 3 is connected to the puncture needle assembly 1. A one-way valve 5 is provided on the first pipe 3. The one-way valve 5 can prevent gas from flowing through the first pipe 3 to the puncture needle assembly 1. The first pipe 3 is also connected to a first connector 2. The first connector 2 is located between the one-way valve 5 and the puncture needle assembly 1. A valve 4 fixed to the first pipe 3 is provided between the one-way valve 5 and the first connector 2.
[0026] In this embodiment, if Figure 1 As shown, the puncture needle assembly 1 includes a catheter 101, a rubber sealing plug 102 is embedded in the top of the catheter 101, a needle core 103 is provided in the catheter 101 and the needle core 103 passes through the rubber sealing plug 102, the rubber sealing plug 102 is made of medical rubber, and the needle core 103 is made of medical stainless steel. The sharp part of the needle core 103 is located outside the catheter 101. When the chest cavity is vented, the sharp part of the needle core 103 is inserted into the patient's chest cavity, so that the catheter 101 is inserted into the chest cavity, and then the needle core 103 is removed from the catheter 101, and the valve 4 is opened. At this time, since the rubber sealing plug 102 will close the top opening of the catheter 101, the gas and effusion in the chest cavity will enter the first pipe 3 through the catheter 101 as the patient breathes, thereby discharging the gas and effusion from the chest cavity.
[0027] When it is necessary to collect a pleural effusion specimen from a patient, the collection tube of the specimen container can be connected to the first connector 2, so that when air and fluid are discharged, the effusion will enter the specimen cavity through the first connector 2, thereby making it convenient for medical staff to sample the patient's pleural effusion without the need for additional puncture operations. Moreover, when it is necessary to administer medicine to the patient's chest cavity, the syringe can also be connected to the first connector 2, so that the syringe can deliver the medicine into the patient's chest cavity through the first connector 2 and the catheter 101, also without the need for additional puncture operations.
[0028] Among them, such as Figure 1 As shown, a water seal bottle 8 is also included. The free end of the first pipe 3 is connected to the second joint 6, and the second joint 6 is connected to the water seal bottle 8 through the second pipe 7. Therefore, the gas discharged through the second joint 6 will enter the water seal bottle 8 through the second pipe 7. Therefore, by observing whether there are bubbles in the water seal bottle 8 and the size of the bubbles, the exhaust volume can be indirectly judged.
[0029] Among them, such as Figure 2 As shown, the first connector 2 and the second connector 6 have the same structure and are both composed of a shell 901 and a rubber plug 902. The rubber plug 902 is made of medical rubber. The rubber plug 902 is embedded in the shell 901 and fixed to the shell 901. The shell 901 of the first connector 2 is connected to the first pipe 3, and the shell 901 of the second connector 6 is connected to the end of the first pipe 3.
[0030] like Figure 1 and Figure 3 As shown, one end of the second pipe 7 is inserted into the water seal bottle 8 and the other end is connected to the needle 701. The end of the needle 701 passes through the rubber stopper 902 of the second joint 6 and is located in the first pipe 3, so that the gas and liquid in the patient's chest cavity can enter the water seal bottle 8 through the catheter 101, the first pipe 3 and the second pipe 7 in sequence.
[0031] like Figure 1 As shown, the catheter 101 is provided with a plurality of through holes 104 , which are located on the side wall of the catheter 101 inserted into the chest cavity. Therefore, gas and liquid can enter the catheter 101 through the through holes 104 , thereby preventing gas and liquid from being unable to enter the catheter 101 due to the bottom of the catheter 101 being blocked.
[0032] Among them, the first pipe 3, the second pipe 7 and the catheter 101 are all soft tubes, and are all made of medical PP material. A length scale is set on the outside of the catheter 101 along the puncture direction, and the puncture depth can be determined by the length scale.
[0033] Working principle: first, the end of the needle 701 is passed through the rubber plug 902 of the second connector 6 so that it is located in the first pipe 3. At this time, the catheter 101 is connected to the water seal bottle 8. Then, the medical staff inserts the sharp part of the needle core 103 into the patient's chest cavity, so that the catheter 101 is inserted into the chest cavity. Next, the needle core 103 is removed from the catheter 101 and the valve 4 is opened. At this time, since the rubber sealing plug 102 will close the top opening of the catheter 101, the gas and effusion in the chest cavity will enter the first pipe 3 through the catheter 101 as the patient breathes, thereby discharging the gas and effusion from the chest cavity into the water seal bottle 8. At this time, by observing whether there are bubbles in the water seal bottle 8 and the size of the bubbles, the exhaust volume can be indirectly judged. Moreover, when it is necessary to sample the patient's pleural effusion, the collection tube of the specimen container can be connected to the first connector 2, so that when exhausting and draining, the effusion will enter the specimen cavity through the first connector 2, thereby facilitating medical staff to sample the patient's pleural effusion without the need for additional puncture operations. Moreover, the syringe can also be connected to the first connector 2, so that the syringe can deliver the liquid medicine into the patient's chest cavity through the first connector 2 and the catheter 101, and no additional puncture operations are required.
