Thoracic water-sealed drainage apparatus

Abstract

The invention discloses a pleural cavity water seal drainage device, which comprises a drainage catheter, a negative pressure regulating valve, a water injection port of a negative pressure monitoring window, a supporting foot and a drainage joint. A hook is provided, and a sampling hole is provided inside the outer shell; the head of the drainage catheter is fixedly connected with a joint, the outside of the joint is wrapped and fixed by an antibacterial sheath, and the end of the drainage catheter is connected to the sampling hole; the surface of the outer shell is inlaid A panel, the panel is provided with a water injection port, and the water injection port is connected with the outer shell, the surface of the panel is provided with a negative pressure monitoring window, and the surface of the panel is marked with the water level line of the water seal cavity. The water-sealed drainage device for the chest cavity has the advantages of simple structure, easy manufacture, small volume, convenient portability, good drainage effect, safety and reliability; it has the function of preventing regurgitation, improves the safety factor of the device, and avoids retrograde infection inside the patient's chest cavity.

Description

technical field [0001] The invention relates to the technical field of medical device applications, in particular to a chest cavity water seal drainage device. Background technique [0002] In many medical scenarios, it is necessary to use a negative pressure drainage device to drain the patient's dirt, but after the drainage is completed, the negative pressure drainage device is generally detached and separated from the patient, and then the dirt is discharged through the outlet of the negative pressure drainage device. However, the switch of the existing negative pressure diverter is generally arranged on the top of the device, and the existing switch is a pull-out type. When dumping each time, the switch of the negative pressure diverter needs to be pulled out to open the outlet of the negative pressure diverter, which is easy to cause Splashing of excretory liquid can easily cause the spread of pollution and increase nosocomial infection, which is not conducive to occupa...

However, the switch of the existing negative pressure diverter is generally arranged on the top of the device, and the existing switch is a pull-out type. When dumping each time, the switch of the negative pressure diverter needs to be pulled out to open the outlet of the negative pressure diverter, which is easy to cause Excrement splashes everywhere, which can easily cause pollution to spread and increase nosocomial infection, which is not conducive to occupational protection and can easily cause sucking back
