Adjustable negative pressure continuous drainage system

Abstract

The invention discloses an adjustable negative pressure continuous drainage system. The adjustable negative pressure continuous drainage system comprises a drainage bottle, a negative pressure regulator, a drainage pipe and a Y-shaped joint, and is characterized in that a liquid inlet is arranged on the drainage bottle, the liquid inlet is connected with the drainage pipe through a Luer joint, a sealing clamp is arranged on the liquid inlet, the negative pressure regulator is arranged on the drainage pipe, the other end of the drainage pipe is connected with the Y-shaped joint, and a one-way valve is connected in the Y-shaped joint. The adjustable negative pressure continuous drainage system disclosed by the invention is safe, smooth, thorough and continuous in drainage, can eliminate a dead space, realize the fit with an incision, form internal fixation and accelerate the healing of a wound, can perform sterile closed drainage and prevent postoperative infection, and can reduce the workload of doctors and nurses, realize convenience in use and adjustable negative pressure value and avoid non-smooth drainage or siphoning caused by too low or too high negative pressure value.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an adjustable negative pressure continuous drainage system. Background technique [0002] At present, after the operation, the patient will form congestion. In order to avoid wound inflammation, cross-infection, and accelerate wound healing, it is necessary to drain the wound. At present, the hospital uses low vacuum negative pressure drainage devices and high vacuum negative pressure drainage devices. The negative pressure drainage device is only suitable for thyroid and breast operations where the negative pressure value is not too high because the negative pressure value is about 10-15kpa. Due to the low negative pressure value, the congestion is not easy to drain, and it is easy to remain in the body. lead to infection, the negative pressure value of the high negative pressure drainage device is about 85-95 kpa, the negative pressure value is too high when it is first...

Problems solved by technology

[0002] At present, after the operation, the patient will form congestion. In order to avoid wound inflammation, cross-infection, and accelerate wound healing, it is necessary to drain the wound. At present, the hospital uses low vacuum negative pressure drainage devices and high vacuum negative pressure drainage devices. The negative pressure drainage device is only suitable for thyroid and breast operations where the negative pressure value is not too high because the negative pressure value is about 10-15kpa. Due to the low negative pressure value, the congestion is not easy to drain, and it is easy to remain in the body. lead to infection, the negative pressure value of the high negative pressure drainage device is about 85-95 kpa, the negative pressure value is too high when it is first used, it is easy to cause siphon, and even cause damage to muscles, tissues and organs, so the scope of operation used is single and cannot It is used in abdominal cavity, thoracic cavity, bone marrow cavity, intracranial and nervous system and other operations, and when used, the drainage time is short and cannot continue to drain, while the negative pressure value required in conventional operations is about 40-60 kpa, while the above two kinds of negative pressure No pressure regulator can be realized, and the negative pressure can not be adjusted, which is extremely inconvenient to use
