[0003] However, the existing T-tube, when in use, is usually only able to drain bile, has low functionality, and is unable to measure the pressure in the bile duct. Therefore, a device for measuring the common bile duct pressure via a T-tube is proposed. Summary of the invention

[0004] The purpose of the utility model is to provide a device for measuring the pressure of the common bile duct through a T-tube, and the setting of installing a plug in the cross tube makes it possible to conveniently measure the pressure in the common bile duct by switching the position of the plug, thereby increasing the function of the product, and at the same time, the guide rod and the positioning block can be used to stably move the plug during its movement, and the plug is positioned at the same time, so as to facilitate the docking of the perforation and the connection hole with the T-tube, thereby solving the existing technical problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] A device for measuring common bile duct pressure via a T-tube, comprising: a T-tube, wherein a liquid outlet end of the T-tube is plugged with a connected cross tube, a plug is slidably connected inside the cross tube, a through hole is provided on one side of the plug, the through hole is used to drain bile, a connecting hole is also provided on one side of the plug, the connecting hole is L-shaped, one end of the connecting hole is located at one side of the through hole and the other end is located at one end of the plug;

[0007] A measuring mechanism is arranged on one side of the cross tube and is used to measure the pressure in the T tube.

[0009] As a further solution of the utility model, a butt tube is inserted into one side of the cross tube, a connecting tube is installed between the butt tube and the U-shaped tube, a rubber membrane is installed in the butt tube, a connecting sleeve is rotatably connected to the circumferential outer wall of the butt tube, and the connecting sleeve is threadedly connected to the cross tube.

[0010] As a further solution of the utility model, a spring is fixedly connected between one end of the cross tube and the plug.

[0011] As a further solution of the utility model, the circumferential inner wall of the cross tube is fixedly connected with a fixing ring, and two penetrating guide rods are inserted on one side of the fixing ring. One end of the guide rods is fixed to the plug, and the other end of the guide rods is fixedly connected with a positioning block used in conjunction with the fixing ring.

During normal use, the T-tube is located in the common bile duct, and the bile drained out enters the cross tube through the T-tube, and then flows into the extension tube through the perforation. The extension tube is connected to the collection bag to collect the bile. When it is necessary to measure the pressure of the common bile duct, the butt-joint tube is connected to the cross tube. During the connection, the butt-joint tube is inserted into the cross tube, and the connecting sleeve is rotated at the same time, so as to fix the butt-joint tube. At this time, the butt-joint tube is connected to one end of the connecting hole. At the same time, when the butt-joint tube is inserted into the cross tube, the plug is pushed to move, and then the perforation is pushed to one side, so that the other end of the connecting hole is connected to the T-tube. The pressure in the T-tube pushes the rubber membrane to deform, and the piston is removed, so as to change the pressure in the U-tube. Then, through the change of the liquid level of the colored liquid in the U-tube, the pressure in the common bile duct connected thereto can be observed. After the measurement is completed, the butt-joint tube is removed, and then the plug is reset under the pushing action of the spring, so as to connect the T-tube with the perforation again, and the bile discharge continues.
