Description

Shielded long-distance radioactive liquid pipet device

The utility model belongs to the labor protection apparatus, especially a kind of device that is used to move liquid packing radioactive liquid.

At present, no matter nuclear technology still on medical and health care system is able to extensive use in industrial and agricultural production, scientific experiment, is improving prevention, diagnosis, treatment disease, study of disease cause of disease mechanism especially, curative effect is indispensable means, but deals with the infringement that also can cause human body improperly.Thereby in the isotopic department of application of radiation, how improving existing preventive means is the problem that faces solution.It is reported that the isotopic department of domestic general application of radiation when radioactive liquid is used in packing, usually adopts hand directly to contact pipette at present, insert and draw radioactive liquid in the pipe or adopt remote aspirator.Used liquid sucking device does not only possess the protecting screen device and does not have control owing to draw radiation liquid, causes water clock to pollute working environment.Thereby the operator uses and to be subjected to a large amount of radiation exposures often, influences the healthy of staff.

The purpose of this utility model is on the basis of remote aspirator, set up and slidably protect lead shield and fluid balance control device, it is convenient to make the operation utensil that moves the liquid packing be tending towards safe and reasonable, be that operating personnel accept radiation exposure and reduce to floor level, further advance this technological means constantly to develop.

Design concept of the present utility model is achieved in that according to ray and can be absorbed by material and exposure and apart from the principle that the square distance of radioactive source is inversely proportional to, makes the operator accept radiation exposure and reduce to floor level.Through my experimental study repeatedly, the slidably protection lead shield and the fluid balance control device that have safeguard function are set up in redesign on the basis based on liquid sucking device, thereby form the remote radioactive liquid suction of the worn-out formula of a kind of screen moving device.

The utility model is made up of protecting screen part and operation control section, comprising lead shield, reflective mirror, long handle, slide bar, control lever, pipette, rubber tube, clamping plate, syringe, the wire clip of band slideway.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the utility model band slideway lead shield structural representation.

Fig. 3 is the structural representation of control lever of the present utility model and rubber tube clamping plate.

Wherein:

(1) protecting screen, (2) slideway, (3) reflective mirror, (4) support,

(5) slide bar, (6) long handle, (7) wire clip, (8) clamping plate

(9) limit pin, (10) control lever, (11) support with holes

(12) pipette, (13) rubber tube, (14) syringe.

Embodiment of the present utility model is to realize like this, the utility model divides protecting screen part and fluid balance control section, the lead shield of its protecting screen part is to be made by the combination of stereotype aluminium sheet, the curved curved surface in surface, it is fixed with slideway (2) behind, this slideway is pressed into by sheet metal, form square duct after being fixed on protecting screen, reflective mirror (3) by support (4) be fixed on the lead shield offside (support in addition end be fixed on the same lead shield face of slideway on) become one with lead shield, form the protecting screen part.The fluid balance control section, its slide bar (5) is the square column type, two symmetrical clamping plate (8) are fixed on its top respectively, respectively be provided with a slot on these clamping plate, long handle (6) is positioned at clamping plate bottom and vertical fixing on slide bar (5), wire clip (7) is fixed in slide bar (5) with long handle (6) reverse vertical to be gone up and the long handle bottom, and the end of slide bar (5) is provided with one and limits pin (9), and long handle (6) is gone up homonymy and fixed two supports with holes (11) respectively.The pipette of operation part (12) is parallel with slide bar and fixing by wire clip (7), and its upper end is connected with rubber tube (13) one ends, rubber tube other end connection syringe (14), and rubber tube is also fixed by the clamping plate that are located on the slideway.Control lever (10) is to be made by metal material or plastics, its front end has a contact head, the rear portion is by the dress operation handlebar, this control lever passes support with holes (11), its contact head inserts in the slot of clamping plate (8), forming control lever advances or return movement in the slot scope and along the duct of support with holes (11), pass through the motion of this control lever by the fixing rubber tube of clamping plate (8), reach the purpose of the radioactive liquid maintenance balance in the control pipette, the liquid water clock can occur and also can not make the intraluminal fluid face exceed the protective range of lead shield, and play remote operated purpose.In the slideway (2) on slide bar (5) the insertion protecting screen of operation control section, it is moved up and down along slideway, thereby form complete suction moving device.Slide bar upper limit rationed marketing (9) guarantees slide bar not slippage in the slideway when slideway moves.

Use of the present utility model is as follows, hand behaviour's long handle (6) will protect lead shield (1) storing and penetrate on the container wall, allow slide bar (5) fall to driving under the pipette (12) along slideway, fall and insert in the liquid container, control syringe (14) sucts liquid, required suction amount is represented with the scale of pipette, and observe by reflective mirror, push lever (10) makes rubber tube stressed after reaching aequum, guarantee that liquid is in poised state this moment in pipe, when mentioning pipette, slide bar (5) rises along slideway and drives the pipette rising, pipette after drawing is inserted in another container, unclamp the control lever rubber tube and be not subjected to external force, operating syringe makes in the pipette liquid pack in the container, finishes the overall process of moving liquid packing radioactive liquid, and slidably no matter protecting screen plays the effect of shielding all the time in drawing radioactive liquid or moving radiographic liquid process.

Advantage part of the present utility model is: this device provides has better safeguard procedures, has guaranteed that namely human body can operate away from radioactive source, has realized again the shielding purpose in the overall process of moving liquid packing radioactive liquid, and has the not function of water clock of control liquid. This apparatus structure advantages of simple, easy to use, draw materials easily, easily promote, be suitable for radioactivity department application in industrial and agricultural production, scientific experiment and the medical and health care system. Use this device, can change the in the past incomplete present situation of some technological means in this field, further promote the development of this technology, for operating personnel provide good condition of work, thereby improve the staff's who is engaged in this work the general level of the health.
