Description

Technical Field

[0001] The present invention relates to the technical field of biliary drainage devices, and more particularly to a drainage device capable of measuring biliary pressure. Background Art

[0002] Biliary obstruction is a disease with a relatively high mortality rate among surgical acute abdomen diseases. Common causes include: acute inflammation (such as acute cholangitis, acute pancreatitis, sclerosing cholangitis, etc.), bile duct stones, foreign bodies in the bile duct (such as biliary parasites, etc.), benign biliary strictures (such as surgical and traumatic biliary scar strictures, etc.), tumors (such as liver cancer, cholangiocarcinoma, gallbladder cancer, duodenal cancer, pancreatic cancer, and lymph node metastatic cancer near the bile duct, etc.), and congenital abnormalities (such as congenital choledochal cyst, etc.).

[0003] Percutaneous transhepatic biliary drainage is to perform biliary puncture through the skin and liver under the guidance of medical imaging equipment using a puncture needle set of equipment and place a catheter for drainage. This operation can treat symptoms such as bile stasis, obstructive jaundice, and secondary infection caused by biliary obstruction, so as to achieve the treatment purpose of restoring liver and gallbladder function. Percutaneous transhepatic biliary drainage includes external drainage, internal drainage, and combined internal and external drainage.

[0004] Existing biliary drainage devices cannot effectively observe the pressure of the drainage tube. If the drainage is not smooth or there is stenosis, it will cause the biliary pressure to rise. In addition, after some patients undergo choledocholithotomy and leave a T-tube for drainage, when the T-tube is elevated during the disease treatment period, the patients will have different clinical manifestations such as jaundice, nausea and vomiting, loss of appetite, and fever. The reason for these symptoms is that the increase in the patient's biliary pressure cannot be detected in the first time, and it can only be discovered until clinical symptoms, signs, or abnormal laboratory test indicators appear.

[0005] In view of this, we now propose a drainage device capable of measuring biliary pressure to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a drainage device capable of measuring biliary pressure, which has a simple structure, is easy to use, can effectively observe the pressure, and can adjust the pressure.

[0014] Further, in the present invention, the telescopic rod is an electric telescopic rod, a pressure sensor is arranged between the sliding plug and the control rod, and the pressure sensor is electrically connected to the electric telescopic rod.

[0015] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0016] Existing biliary drainage flexible tubes are prone to leakage between the puncture drainage orifice and the catheter, and it is also easy to have the situation that the T-tube is too high and the biliary pressure suddenly rises.

The present invention is provided with a pressure measuring tube 1. The pressure measuring tube 1 is connected to the drainage hose 4, so that the biliary pressure of the patient can be communicated through the drainage hose 4 into the pressure measuring tube 1, forming a pushing pressure on the calibration liquid 2, and cooperating with the air spring formed by the air on one side of the calibration liquid 2, so that medical staff can quickly observe the pressure condition in the bile duct through the movement of the calibration liquid 2, and timely discover abnormal pressure changes in the patient's bile duct, so as to take active and effective treatment measures. The sliding plug 10 is connected with a control rod 12, so that medical staff can pull the sliding plug 10 through the control rod 12, thereby adjusting the position of the calibration liquid 2 to avoid inaccurate measurement during installation or use at different altitudes.

[0028] Further, in the present invention, the above-mentioned pressure measuring tube 1 is arranged in an inverted "U" shape, and scale lines are arranged along its length direction. The pressure measuring tube 1 arranged in an inverted "U" shape can facilitate medical staff to intuitively judge the pressure condition in the bile duct by setting the calibration liquid 2 at its highest point; the setting of the scale lines is convenient for observing the specific pressure condition.

[0029] Further, in the present invention, a plurality of annular protrusions 11 are arranged on the outer side of the above-mentioned sliding plug 10. The arrangement of the plurality of annular protrusions 11 can effectively increase the airtight effect and avoid leakage during the moving process.
