Description
Technical field
This utility model belongs to medical instruments field, especially relates to a kind of oral cavity combined therapy desks water route resorption detector.
Background technology
Oral cavity combined therapy desks (Dental Chair Unit, DCU) the is integrated apparatus system of various complexity, comprises the necessary apparatus parts of water, electricity, gas feed system and various dental diagnostic.Oral cavity combined therapy desks water route (Dental Unit Waterlines, DUWLs) is the interconnective pore pipeline of a set of complexity, and it flushes out confession water to all DCU apparatuses that are attached thereto, cup water filling port and bowl type.DUWLs water outlet can be used for cooling as apparatuses such as conventional dental handpiece, triple syringe and ultrasonic cavitrons, also in oral cavity diagnosis process, rinses dental surface.
Study and show both at home and abroad, DUWLs water outlet bacterial concentration can be up to 10
6cFU/mL, must not exceed the standard of 100CFU/mL far beyond China's Drinking Water.Moreover DUWLs water outlet is to be applied in medicine and hygiene fields, there is immunodeficiency, operation on oral cavity, disease of pulp of tooth patient for those, DUWLs water outlet is polluted so serious, will be the important hidden danger that causes hospital infection event to occur.
The reason that bibliographical information DUWLs water outlet is polluted, except bringing part microorganism in source water, the more important thing is that in diagnosis and treatment process triple syringe, dental handpiece stop moment in startup and form negative pressure, liquid resorption in mouth is entered to DUWLs causes.In order to reduce because of Suction contamination DUWLs, most is taked to install anti-resorption valve in DCU and is used the mobile phone with anti-resorption function.But, although most of DCU has installed anti-resorption valve, but still there is the present situation of current DUWLs water outlet severe contamination.Have report prompting abroad, the anti-resorption valve of DCU crash rate is up to 74%.
Although it is more and more that China pays close attention to the infection control personnel of DUWLs pollution problem, be confined in the seriously polluted degree of DUWLs water outlet and control measure more.Although professional admits from source control resorption and is only the essential measure that real solution DUWLs pollutes, but effectively supervise and there is no a resorption checkout gear finished product owing to lacking, cause resorption in the time dispatching from the factory, to detect, in regular job, be difficult to find whether anti-resorption valve lost efficacy, and whether the problem such as need repairing.
Pharmaceuticals industry standard " odontology dental unit part 2: supply water and air feed (the YY/T0630-2008/ISO7494-2:2003) " regulation that State Food and Drug Administration issues, the moment kinetics pressure producing due to shutdown changes the resorption amount that the water, air and other media that cause return to DCU and can not exceed 40uL, and can formulate " ANSI/ADA 47-2006 dental equipment " regulation resorption can not to exceed 40.3uL identical with American National Standards Institute (ANSI) and U.S.'s odontology.
And be not all to be connected under the prerequisite of dental handpiece for two standards of detection method China and the U.S. of DCU resorption, dental handpiece pipe joint need be taken off, isolate the method operation that wherein water route water pipe detects according to resorption again.There are several defects in this operation, and the one, the dismounting of dental handpiece pipe joint needs special tool(s) and professional skill, and take-down time and set-up time are long, are not suitable for monitoring in batches.The 2nd, in the time not connecting dental handpiece, trample control backpedalling brake, gases at high pressure and water can spray simultaneously, cause and splash.The 3rd, still there is no the finished product of monitoring tool in industry standard.

The technical solution of the utility model is: oral cavity combined therapy desks water route resorption detector, comprise joint, flexible pipe and dip stick three parts, the two ends of described joint are respectively arranged with Pagoda-shaped interface and pipeline link, described Pagoda-shaped interface is connected with one end of flexible pipe, the other end of described flexible pipe opens wide, described pipeline link is made up of threaded portion and connecting portion, mate with oral cavity combined therapy desks dental handpiece end of line interface thread described threaded portion, the bottom of described connecting portion is provided with rubber washer, make described joint be connected tightr with oral cavity combined therapy desks dental handpiece end of line, described dip stick middle part is provided with groove, the shape of the shape of described groove and flexible pipe and joint adapts, described flexible pipe and joint can embed groove fixing, the edge of described groove is provided with graduation mark, " 0 " scale flushes with an end margin of dip stick.
Further, described connecting portion meets the C type connector in dental handpiece hose connector, has four jacks to be connected with the corresponding interface on oral cavity combined therapy desks dental handpiece above.
Further, described groove is made up of groove front end, groove middle-end and notch end, the shape of described groove front end and the shape of flexible pipe adapt, described hose main body is partially submerged into groove front end, the Pagoda-shaped interface of described joint embeds groove middle-end, the main part of described joint embeds notch end, and described pipeline link extend out to outside dip stick, is connected with oral cavity combined therapy desks dental handpiece pipeline.
Further, in described dip stick, the precision of graduation mark is 1mm.
Further, the length of described flexible pipe is slightly longer than the length of graduation mark.
The advantage the utlity model has with good effect is: this oral cavity combined therapy desks water route resorption detector can effectively separate water, gas in oral cavity combined therapy desks mobile phone pipeline, possesses feature simple, effective, easy operating, and the length of instruction oral cavity combined therapy desks water route, water route resorption by retaining, thereby calculate resorption amount, for judge the anti-suck back valve of oral cavity combined therapy desks whether effectively, whether need repairing to change provides foundation.
