Subcutaneous inflatable drainage support frame

Abstract

The invention discloses a subcutaneous inflatable drainage support frame which comprises a drainage tube, a liquid inlet, an air bag, a latex short tube, an air guide tube, a first connector, an air pressure sensor, a second connector, an exhaust pipe, an electromagnetic valve, a third connector, a pressurizing pipe, a one-way valve, a micro air pump, a PCB and a single-chip microcomputer. The airbag is placed in the wound, and the interior of the wound can be supported through the inflation effect of the micro air pump, so that the effusion flowing speed is increased, and the situation thatliquid drainage is affected due to interception of internal tissues of the wound is prevented; the change of air pressure in the air bag is monitored in real time through the micro air pump; when theair pressure in the air bag is insufficient, the air pump automatically inflates air into the air bag, so that the drainage efficiency is guaranteed; and when the air pressure in the air bag is too high, the electromagnetic valve is opened to exhaust redundant air to prevent the air pressure in the air bag from being too high to injure a patient; the air pressure sensor, the exhaust pipe and the pressurizing pipe are connected with the air guide pipe in a threaded connection mode and cannot make contact with a patient.

Description

technical field [0001] The invention relates to a support frame, in particular to a subcutaneous inflatable drainage support frame, which belongs to the technical field of drainage support frames. Background technique [0002] Drainage tube is a medical device used for clinical surgical drainage to guide pus, blood and liquid accumulated between human tissues or body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage tubes used clinically. , Some are used for catheterization, some are used for wounds, thoracic cavity, brain cavity, gastrointestinal tract, biliary tract, etc. have applications. [0003] In clinical practice, when pus, blood and other body fluids are squeezed at the wound of human tissue, the drainage tube is directly inserted into the wound, and the body fluid is discharged through the drainage function of the drainage tube. They are connected with each other, which will...

Problems solved by technology

[0003] In clinical practice, if pus, blood and other body fluids are squeezed at the wound of human tissue, the drainage tube is directly inserted into the wound, and the body fluid is discharged through the drainage effect of the drainage tube. Interconnection between body fluids will interfere with the normal flow of body fluids, resulting in poor drainage; when human tissues are injured or empyema, the wounds wil
