The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with the specific embodiment and coordinate accompanying drawing to be explained in detail.
The utility model proposes a kind of ultrasonic cleaning organization, the sample needle that can carry out biochemical luminous measuring instrument by spring formula flush clean mode cleans.Fig. 1 shows the schematic perspective view for the ultrasonic cleaning organization of sample needle.Basic principle of the present utility model is the mode that hydraulic pressure cleans and ultrasonic cleaning combines that adopts spring formula, when hydraulic pressure cleans, add high-intensity ultrasonic, utilize high strength supersonic in cleaning fluid, to produce cavitation effect, act on the sample needle wall being cleaned, thereby reach efficiently cleaning performance fast.
Fig. 2 is the modular construction schematic diagram of ultrasonic cleaning organization described in the utility model.Described ultrasonic cleaning organization adopts the design of focused transducer, comprises a ultrasonic transducer 5, and this ultrasonic transducer 5 connects drive circuit 6, thereby makes the oscillator vibration of transducer produce ultrasonic wave; The oscillator top of transducer is the focus ultrasonic body 10 of trumpet type, is the diminishing tubaeform shape of diameter from the bottom to top.The top of focus ultrasonic body 10 has one with the end 11 of fluted I, can be referring to the zoomed-in view of Fig. 3, and the bottom surface of described groove I is sealed, and its side is also in closed state.The top periphery of focus ultrasonic body 10 is surrounded with liquid collector, for collecting, clean the rear cleaning waste liquid producing, in the present embodiment, this liquid collector is the disk 3 an of polythene material (or other waterproof materials), the diameter 25mm-40mm of disk, and the two binding site of the top of focus ultrasonic body and disk has the seal washer 2 of O type.Certainly, according to the factor of the aspects such as configuration design of product, also liquid collector can be configured to other shape, such as being configured to square plate or bowl-type etc.The side-lower of disk 3 is scavenge pipes 4, and scavenge pipe 4 is communicated with interior realization with disk by liquid outlet; The annexation of described disk and scavenge pipe can be referring to the profile of Fig. 4.Scavenge pipe 4 below ends are connectors 9, can be used for external catheter.When installing, by jacking block 7, the bottom of ultrasonic transducer 5 is withstood, then by interior hexagonal cylindrical head dummy hold-down screw 8, jacking block 7 is fixing.
Apply the process that ultrasonic cleaning organization described in the utility model cleans sample needle as follows: first, utilize load maintainer to carry the top groove I top that sample needle 1 moves to wiper mechanism, make the front end of sample needle rest on the position (referring to Fig. 2 and Fig. 3) below the top edge of groove I, by sample needle liquid feed device, to the sample needle 1 of hollow, supply with cleaning fluid, thereby make sample needle 1 toward groove I ejection cleaning fluid.Described cleaning fluid comprises any one in deionized water, distilled water or sample needle special cleaning, can be also any two or more mixed liquor in deionized water, distilled water or sample needle special cleaning.The Cleaning Process liquid of hydrojet flows through the inwall of sample needle 1, the inwall of sample needle is produced to the effect of flush clean; Cleaning fluid is with the sealing bottom surface of constant compression shock groove I, thereby returned to form spring by bounce-back, the fore-end of the cleaning fluid submergence sample needle 1 of spring formula, and the outer wall of sample needle 1 is there is to the effect of flush clean.The utility model has adopted the size through optimal design for diameter, groove depth and the outer end diameter of groove I, and the diameter of its further groove I is 3.2mm-5mm, and groove depth is 5mm-10mm, and the external diameter of described end 11 is 6mm-10mm.This size can coordinate the cleaning way of spring formula, improves flush efficiency, saves scavenging period and reduces costs.Equally, in order fully to form spring, the hydrojet pressure that the utility model adopts is 40kPa-80kPa, and cleaning fluid flow is 0.1L/min to 0.5L/min, is preferably 0.3L/min.If hydrojet pressure and flow are less than above-mentioned hydrojet pressure and flow number through optimizing, its impact to groove floor is not enough, and formation spring effectively cannot rebound; Otherwise, if hydrojet pressure and flow are greater than above-mentioned optimization numerical value, sample needle itself can bear excessive internal pressure, be unfavorable for guaranteeing its service life, and bounce-back effect is excessively strong, can make cleaning fluid from groove top, overflow in a large number, cause inside grooves liquid storage quantity not sufficient, be unfavorable for equally forming fully spring.In the process of whole hydrojet, ultrasonic generator 5 is in normal operating conditions, and its supersonic frequency is 40kHz-60kHz, and ultrasonic power is 2W-30W.The ultrasonic power of ultrasonic generator 5 is focused on the position of groove I, thereby makes the cleaning fluid in groove I produce great acoustic pressure, and then produces strong cavitation effect.Because the cavitation effect of cleaning fluid can produce the HTHP of moment at the inside and outside wall of sample needle 1, the HTHP of this moment acts on the inside and outside wall of sample needle, thereby peels off the pollutant of sample needle 1 inside and outside wall, and drains by the cleaning fluid springing up.The duration that each hydrojet is cleaned is about 600ms-1000ms.Clean waste liquid and gush out from the top of groove, and collect by disk 3, finally by scavenge pipe 4, drain.Like this, bottom surface and the sidewall of groove all seal, and do not need to be provided for the perforate of feed flow and discharge opeing.After cleaning completes, sample needle 1 stops hydrojet, and ultrasonic generator 5 quits work, and sample needle 1 leaves wiper mechanism and once moves liquid on carrying out under load maintainer carries.
Ultrasonic cleaning organization structure described in the utility model is relatively simple, small volume, the space that can save instrument; By groove structure, design, make sample needle without going deep in cleaning fluid, easy to operate quick, and avoid sample needle outer wall section to be immersed in the problem of bringing in cleaning fluid; By sample needle, directly spray cleaning fluid, structure is simpler, and sample needle inwall is had to good cleaning action.Clean generation waste liquid and directly by peripheral passage, drained, simple and convenient.Special feed flow and draining mode, make groove present closed state, thereby kept the integrality of focus ultrasonic end of body, is more conducive to ultrasonic transmission and assembles and form cavitation effect, improved efficiency and the effect of cleaning.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
