Description
This utility model relates to a kind of full-automatic washing and sterilizing machine for endoscope of medical instruments field.
The range of application of scopes such as gastroscope, bronchoscope, esophagoscope, duodenoscope is more extensive, need probe into inside of human body during owing to use, after each the use, all should carry out strict cleaning and sterilization.At present, most of hospitals still adopt artificial method, and promptly " three barrels of methods " is to the scope decontamination.The shortcoming of this method is conspicuous: time-consuming, the sterilization imprecision easily causes the cross infection between the patient.On the other hand, the hand-held scope body of medical personnel carries out manual operations, unavoidable crooked, strip is straight, easy damaged endoscopic optical fibers bundle.For this reason, before the several years, Shanghai enterprise once manufactured experimently a kind of simple type disc type washing machine, its shortcoming be centrifugal water dumping, water along circumference disperse, a little less than the impulsive force, unidirectional decontamination has dead angle, sterilization not thorough, noise is also big in addition.A kind of vertical automatic washing and sterilizing machine for endoscope of Beijing production of units, its shortcoming are that volume is big, too high, the inconvenient operation of scope hanging position; Mechanical transmission structure is complicated, noise is big, power consumption is high, is not the maintenance straight line when scope is draped, but certain bending is arranged, so during cleaning, shower nozzle moves up and down and runs into the external epidermis of mirror easily.And because the cost height is not extensive in hospital application at present.
The purpose of this utility model provides a kind of scope that neither damages, and sterilization is thorough again, and structural behaviour is good, and is applied widely, and fault rate is extremely low, meets the ergonomic principle, scope washing equipment easy to use---full-automatic washing and sterilizing machine for endoscope.
The purpose of this utility model is achieved through the following technical solutions, a kind of by casing, liquid feed device, rinser, the full-automatic washing and sterilizing machine for endoscope that power set and automatic program control constitute, it is characterized in that rinser is by the benzvalene form decontamination room, turriform spray frame, the bootstrap type dynamic sealing assembly, the flexible net grid, two advance one goes out transfer valve, the one-in-and-two-out transfer valve constitutes, be processed with the scope lead-in groove on the benzvalene form decontamination room, the bootstrap type dynamic sealing assembly is fixed on benzvalene form decontamination room bottom center through securing member, fixing turriform spray frame on the central tube of bootstrap type dynamic sealing assembly, the flexible net grid place in the benzvalene form decontamination room and cover turriform spray frame, the feed pipe of bootstrap type dynamic sealing assembly and two advances one and goes out transfer valve and be connected, and two enter two inlet sides that out transfer valve links to each other with the clear water booster pump with medicinal liquid booster pump in the power set through pipeline respectively.The bootstrap type dynamic sealing assembly is made of central tube, central axle sleeve and sliding ring; Sliding ring is made by polytetrafluoroethylmaterial material; Turriform spray frame is made of last spray arm, lower spraying arm, flat fan smooth-bore tip, fan-shaped oblique flow nozzle, and the flat fan smooth-bore tip is fixed on the two ends of lower spraying arm, and fan-shaped oblique flow nozzle is fixed on the two ends of spray arm; Being 90 ° between the last spray arm of turriform spray frame and the lower spraying arm is fixed on the central tube.
This utility model can make scope be naturalness in the benzvalene form decontamination room and deposit, thereby when decontamination, can not damage scope, prolonged the service life of scope, novel bootstrap type dynamic sealing assembly, be to utilize hydraulic pressure or medicinal liquid pressure to produce rotary power and sealing function, make that the shower nozzle scanning speed is even, decontamination does not have the dead angle, sterilization is thoroughly effective, easy and simple to handle, the operator only need connect water, power supply, start back washing machine just carries out according to the Automatic Program of " cleaning---sterilization---cleans ", finishes decontamination work in a few minutes.
Accompanying drawing 1 is this utility model structural representation;
Accompanying drawing 2 is this utility model bootstrap type dynamic sealing assembly and turriform spray shelf structure sketch map;
In the accompanying drawing: the 1st, central tube, the 2nd, scope lead-in groove, the 3rd, bootstrap type dynamic sealing assembly, the 4th, automatic program control, 5 is two to advance one and go out transfer valve, the 6th, and medicinal liquid booster pump, the 7th, blow-off pipe outlet, the 8th, water inlet, the 9th, casing, the 10th, spray tank, the 11st, the clear water booster pump, 12 and 13 is one-in-and-two-out transfer valves, the 14th, flexible net grid, the 15th, benzvalene form decontamination room, the 16th, top cover, the 17th, last spray arm, the 18th, lower spraying arm, the 19th, central axle sleeve, the 20th, rotary packing ring, the 21st, securing member, the 22nd, feed pipe.
Now further specify this utility model in conjunction with the accompanying drawings and embodiments, after energized, automatic program control 4 is according to " cleaning---sterilization---program of cleaning; control clear water booster pump 11; medicinal liquid booster pump 6, two advances an electromagnetic valve and the work of the interlocking mechanism between top cover 16 and the casing 9 that outes in transfer valve 5, the one-in-and-two-out transfer valve 12,13; scope that needs decontamination is in scope lead-in groove 2 slips into the flexible net grid 14 of benzvalene form decontamination room 15 naturally, and bootstrap type dynamic sealing assembly 3 is made of central tube 1, central axle sleeve 19, politef rotary packing ring 20.When no hydraulic pressure or medicinal liquid are pressed, central tube 1 is owing to deadweight falls, after adding hydraulic pressure or medicinal liquid pressure, central tube 1 top is upwarded pressure lifts (when F=PS conducts oneself with dignity greater than the spray frame), and central axle sleeve 19 fits tightly with politef rotary packing ring 20 lower surfaces, and pressure is big more, the applying degree is strong more, pressure to a certain degree, is fitted no leakage greatly fully.Because rotary packing ring 20 adopts polytetrafluoroethylmaterial material, its chemical stability is extremely strong, and coefficient of friction is minimum in all material, so frictional force is also little.The recoil of nozzle high-speed liquid stream produces recoil moment.Total trend is, along with increased pressure, the nozzle flow velocity increases, and recoil moment strengthens, simultaneously, central tube 1 from lifting force increase, moment of friction strengthens thereupon.Vice versa, and recoil moment and moment of friction condition each other, and guarantees stabilization of speed.Turriform spray frame is made of last spray arm 17, lower spraying arm 18 and the flat fan smooth-bore tip that is fixed on the fan-shaped oblique flow nozzle at spray arm 17 two ends and is fixed on lower spraying arm 18 two ends.Last lower spraying arm is divided into two-layer in vertical direction, every group of two nozzles are symmetrically distributed with the central tube axis, and four nozzle projections are along the circumferential direction uniform.Each nozzle is 90 ° of cross arrangements in movement locus projection perimeter.During central tube 1 rotation, every nozzle washes along circular scanning.Scope is natural torsion and spirals, during water spray, lower floor's nozzle vertically upward, High-Pressure Water is flat fan and penetrates rinse endoscopes bottom surface and both sides; The upper strata nozzle, the oblique High-Pressure Water that outwards sprays down, section is flat wedge face, and no any dead angle is cleaned in rinse endoscopes upper surface and both sides.Water inlet 8 and blow-off pipe outlet 7 usefulness as water inlet and blowdown.Spray tank 10 links to each other with medicinal liquid booster pump 6, and the medicinal liquid in the benzvalene form decontamination room 15 flows back to spray tank 10 through one-in-and-two-out transfer valve 13, and the water in the benzvalene form decontamination room 15 flows out from blow-off pipe outlet 7 through one-in-and-two-out transfer valve 12.
