Description

Thoracoperitoneal drainage device

technical field

The invention relates to the field of medical appliances, in particular to a thoracoabdominal cavity puncture and drainage device.

Background technique

Clinically, thoracoabdominal puncture and drainage are often performed to drain the effusion for patients whose thoracic and abdominal cavities are full of pleural and ascites to relieve the pain of the patient, and some patients need repeated punctures. The puncture and drainage device currently used clinically consists of a puncture needle, a syringe and a rubber tube connecting the two. During the operation, when the syringe is full of effusion, clamp the rubber tube with a hemostat, separate the syringe from the rubber tube, drain the effusion in the syringe, and then reconnect the rubber tube. Repeated operations, air or bacteria It is easy to enter the body cavity and cause pollution, which is very unsafe, and two people are required to operate it, which is very cumbersome. Therefore, it is necessary to design a drainage device that uses a drainage tube connected to a drainage bag at the end to directly drain out the pleural and peritoneal effusions, and to realize a reliable connection between the drainage tube and the puncture catheter with two different diameters.

Contents of the invention

In order to solve the above problems, the purpose of the present invention is to provide a puncture and drainage device for pleural and peritoneal effusion, which can realize reliable connection between the drainage tube and the puncture catheter, and can be used for injecting medicine at the same time.

In order to achieve the above object, the present invention adopts the following technical solutions:

The thoracoabdominal puncture drainage device includes a puncture catheter, a 2cc syringe, a drainage tube, and a drainage bag. The drainage tube includes three interconnected branch pipes A, B, and C. The mouth of the branch A is provided with a pagoda joint. The pagoda joint is provided with a through hole communicating with the inside of the branch pipe A, and the branch pipe B is equipped with a Murphy's dropper and a speed control switch. There is a one-way valve, the nozzle of the branch pipe C is equipped with a heparin cap, the injection end of the 2cc syringe is matched with the puncture catheter, the injection end of the 2cc syringe is inserted into the puncture catheter, the pagoda connector is matched with the cylinder of the 2cc syringe, and drainage The pagoda connector on the tube is inserted inside the barrel of the 2cc syringe.

The above-mentioned tracheotomy tube has the following advantages: (1) 2cc syringe is a commonly used medical device, and the production cost is low. By setting the 2cc syringe, the size conversion between the puncture catheter and the drainage tube can be realized, and the puncture catheter and drainage tube can be realized. Reliable connection between tubes, easy to use; (2) Setting the speed regulating switch can easily adjust the speed of effusion discharge, and the flow rate can be observed intuitively through the Murphy's dropper; (3) Set the one-way valve and heparin cap, and With the speed control switch, it can be used for injecting medicine at the same time after one puncture.

detailed description

The preferred embodiments of this patent will be described in further detail below in conjunction with the accompanying drawings.

Thoracoabdominal puncture generally includes the following steps: 1) puncture with a puncture needle, take out the puncture needle after the puncture is completed, and leave the indwelling tube on the puncture needle at the puncture port; Indwelling tube; 3) The spreader is inserted into the puncture port along one end of the lead wire, the puncture port is enlarged, and the lead wire is taken out; 4) The puncture catheter is inserted into the spreader and fixed, and then the spreader is taken out.

A thoracoabdominal puncture and drainage device as shown in Figure 1 is assembled after the above steps are completed, including a puncture catheter 1, a 2cc syringe 2, a drainage tube 3 and a drainage bag 4, and the drainage tube 3 includes branch pipes that communicate with each other Three branch pipes of A31, branch pipe B32 and branch pipe C33, the nozzle of branch pipe A31 is provided with pagoda joint 311, is provided with the through hole that communicates with branch pipe A31 inside on pagoda joint 311, is provided with Murphy's dropper 5 and adjuster on branch pipe B32 Speed switch 6, the lower end of the branch pipe B32 is connected to the drainage bag 4, and the lower end of the drainage bag 4 is provided with a drain port. Since the diameter of the puncture catheter 1 is small and that of the drainage tube 3 is relatively large, a 2cc syringe 2 is used for pipe diameter conversion. The injection end of the 2cc syringe 2 cooperates with the puncture catheter 1, the injection end of the 2cc syringe 2 is inserted and fixed in the puncture catheter 1, the pagoda joint 311 is matched with the barrel of the 2cc syringe 2, and the pagoda joint 311 on the drainage tube 3 is inserted into the puncture catheter 1. Set to be fixed inside the barrel of the 2cc syringe 2. The flow direction of pleural effusion is puncture catheter 1->2cc syringe 2->branch tube A31->branch tube B32->drainage bag 4, and the lower end of the drainage bag 4 is provided with a discharge port. The drainage speed of the pleural and peritoneal effusion and the opening and closing of the drainage tube 3 can be controlled by the speed regulating switch 6 , and the flow rate can be visually observed through the Murphy's dropper 5 . A one-way valve 7 is provided on the branch pipe C33, and a heparin cap 8 is provided at the nozzle of the branch pipe C33. Cooperating with the speed regulating switch 6, the drug injection can be realized.

When in use, first empty the air in the drainage bag 4, turn off the speed control switch 6, and maintain a negative pressure state. After determining the puncture site, the doctor performs the puncture according to the steps of the puncture operation. After the puncture is completed, one end of the catheter 1 is punctured. Keep it in the thoracic and abdominal cavity for drainage. At the same time, connect one end of the puncture catheter to the branch tube A31 of the drainage tube 3 through the 2cc syringe 2 in time. After that, turn on the speed control switch 6. Enter the drainage bag and enter the normal drainage process. After the drainage is completed, if it is necessary to inject medicine into the thoracic and abdominal cavity, it can be directly injected from the heparin cap 8 without additional puncture, which reduces the pain of the patient.
