Description

Water-gas separation quick sampling joint for dental handpiece pipeline
Technical Field
The utility model belongs to medical instrument equipment field especially relates to a swift sampling of dental handpiece pipeline aqueous vapor separation connects.
Background
The oral cavity comprehensive treatment table is a necessary comprehensive medical instrument for oral cavity diagnosis and treatment, and integrates a water supply system, an electric supply system and a gas supply systemInstrument parts necessary for dental diagnosis and treatment. The water from the waterway of the oral cavity comprehensive treatment table can be used for cooling instruments such as a conventional dental handpiece, a three-purpose gun, an ultrasonic tooth cleaner and the like, and can also be used for washing the surfaces of teeth in the oral cavity diagnosis and treatment process. Domestic and foreign research shows that the concentration of bacteria in the waterway of the oral comprehensive treatment table can be as high as 106CFU/mL is far beyond the standard that drinking water in China cannot exceed 100CFU/mL, and has important hidden danger of occurrence of hospital infection for patients with immunodeficiency, oral surgery and dental pulp diseases. At present, the microbial index limit value of the waterway effluent of the oral cavity comprehensive treatment table is not released in China, but related local standards are released in succession in Tianjin, Beijing, Jilin, Zhejiang and the like, and a standard basis is provided for standardizing the waterway pollution of the oral cavity comprehensive treatment table. However, the waterway effluent sampling method of the oral cavity comprehensive treatment table is not unified, and the main problems are that if the terminal of the dental handpiece pipeline of the oral cavity comprehensive treatment table is used for collecting, the disassembly and the assembly of the pipe joint of the dental handpiece require special tools and professional skills, the disassembly time and the assembly time are long, the method is not suitable for batch monitoring, and if the method is not disassembled, the problems of simultaneous spraying of water and air, small collection amount, low collection speed, mixed pollution and the like can occur. If the three-purpose gun is used for collecting water discharged from the water channel, the problems can be avoided, but the concentration of bacteria in the water discharged from the three-purpose gun on the surface of a large number of documents is obviously lower than that of the water discharged from the water channel of the dental handpiece, so that false negative is easily caused. Therefore, a simple and efficient quick sampling joint for separating water and gas is needed to be developed to facilitate sampling of medical staff and third-party detection staff.
The compressed air is an important air source and a power source of the oral cavity comprehensive treatment table and can be used as the scrap blowing air of the three-purpose gun and the driving air of the dental handpiece in the oral cavity diagnosis and treatment. The waste gas generated by the blowing air and the dental handpiece can be directly contacted with the oral mucosa of a patient or inhaled by a doctor or the patient in the form of aerosol. Because the oral cavity clinic has the characteristics of more civil and camp clinics, small scale of a clinic area, more dispersed air supply of compressed air and the like, the serious waterway pollution of the oral cavity comprehensive treatment table is not well treated, and the pollution of the compressed air is paid attention to by less people. It has been reported that sampling by a three-way gun air passage of an oral cavity comprehensive treatment table is positive in culture of 24% of samples. Gas path bacterial concentration in dental handpieceDegree of 22CFU/m3And staphylococcus aureus, bacillus, oslomora roseola and the like are separated. At present, the collection of compressed air is mainly collected through related sampling equipment, and how to connect the compressed air output from the tail end of the dental handpiece of the oral cavity comprehensive treatment table with the sampling equipment is a problem to be solved.
