Medical hydrops extractor

Abstract

The invention discloses a medical hydrops extractor. The extractor comprises a hydrops taking bottle, a first scale line is arranged in the hydrops taking bottle, and a fixing rack is arranged at oneside of the hydrops taking bottle; a connection line is arranged at one side of the fixing rack, a dustproof sleeve is arranged at one side of the connection line, and a supporting rack is arranged atthe other side of the hydrops taking bottle; an arc rubber soft plate is arranged on the supporting rack, a nylon adhesive tape is arranged on the arc rubber soft plate, and an extraction device is arranged above the hydrops taking bottle and internally comprises a hydrops suction cavity and an extraction cavity; a piston is arranged in the extraction cavity, an extraction rod is arranged at oneside of the piston, and a hydrops inlet is formed in the hydrops suction cavity; an air discharging one-way valve is arranged above the extraction device, a hydrops suction hose is arranged at one side of the air discharging one-way valve, a fixing base is arranged at one end of the hydrops suction hose, and a hydrops suction needle is arranged at one side of the fixing base. The medical hydrops extractor is convenient to use, a medical worker conveniently operates the medical hydrops extractor, and the medical hydrops extractor is suitable for application and popularization.

Description

technical field [0001] The invention relates to a medical effusion extractor, specifically belonging to the technical field of medical equipment. Background technique [0002] Synovitis is a common clinical disease, the main symptom is knee joint effusion. The knee joint is composed of the medial and lateral condyles of the femur, the medial and lateral condyles of the tibia, and the patella. It is the largest joint in the human body with the most complex structure and more opportunities for injury, so there are more opportunities for injury and infection. Knee synovitis is mainly a group of syndromes caused by knee sprain and various intra-articular injuries. Such as meniscus injury, synovial injury, cruciate ligament or collateral ligament injury, intra-articular injury and dislocation, knee osteoarthritis secondary to knee joint chronic synovitis and joint loose bodies, etc. Another reason is infection, the most common of which is synovial tuberculosis. Generally speaki...

Problems solved by technology

[0003] In the treatment of periostitis, an effusion extractor is needed to extract the effusion in the knee joint, but the existing effusion extractor is not convenient for medical staff to use, and requires the cooperation of multiple medical staff to use

When the medical personnel insert the liquid suction needle of the effusion extractor into the knee, one hand needs to hold the liquid suction needle to control the insertion depth of the liquid suction needle to prevent it from falling off suddenly when the liquid is sucked, because the liquid collection bottle is not fixed However, the other hand cannot pull the extraction rod independently. At this time, another medical staff needs to fix the liquid extraction bottle and pull the extraction rod to extract the effusion. This operation is too cumbersome and not conducive to use. If there is only one medical staff It is difficult to perform effusion extraction in the case of

Moreover, the structural design of the part of the effusion extractor is unreasonable. During the process of effusion extraction, when the effusion flows from the suction hose into the liquid suction chamber, it will accumulate on the side of the liquid inlet, and the bottle needs to be shaken to remove the effusion. Pour it into the extraction liquid bottle, and the diameter of the liquid inlet is small. If the extracted fluid is too much, it may flow into the extraction chamber as the piston is pulled, which will easily cause problems with the sealing of the piston and cause the extraction of the extractor. Extraction efficiency is not high
