Description
The utility model relates to a kind of improvement of medical apparatus, and specifically a kind of nuclear medicine in-vitro diagnosis detects uses bead wahser.
The in-vitro diagnosis of nuclear medicine partly is exactly to extract patient's external secretion (as blood, urine etc.), and the application of radiation immuno analytical method detects the micro substance in patient's secretion then, changes by observing it, thereby reaches the purpose that diagnoses the illness.
We detect many microcomponents of patient at present, as the external tag material of series such as hepatitis (as HB
sAg, SAb etc.), usually be marked on the plastic beads and (often be called the reaction pearl) with known Ag or Ab, add patients'blood or urine then, after certain hour reacts completely, the Ag/Ab of our patient's body fluid of detecting just combines with known Ab/Ag on the reaction pearl securely like this, adds the label (I commonly used of Ag/Ab then
125Mark) with after the compound of reaction on the pearl fully combines, the radiation content on the assaying reaction pearl can be tried to achieve the content of micro substance in patient's body fluid.Because the composition complexity in patient's body fluid, when behind reaction pearl and the patient's humoral response and the reaction pearl with usually have many non-specific materials (being non-detection composition) and the composition that reacts on the pearl to produce non-specific bond after label combine, thereby influence the mensuration of detection composition.In order to reduce non-specific bond composition on the reaction pearl, after all the reaction pearl thoroughly must being washed 2-3 time with distilled water after each reaction, and then carry out next step operation.
We adopt manual operations by the washing reaction pearl sometimes at present.The reaction pearl is in the plastic test tube bottom, the Plastic Drum that fills distilled water is placed on the certain altitude, end at a rubber tube is pressed a draw point suction nozzle, utilize siphon principle, rubber tube one end is fixed and is placed on the bottom of Plastic Drum, the distilled water of the other end adds to test tube with hand one by one by the draw point suction nozzle, open the negative pressure sucking pump then, after reaching certain pressure, take draw point (end is connected with sucking pump by plastic tube) to insert test tube one by one with hand again, with invisible spectro distilled water exhaustion, the soiling solution of absorption is inhaled in a vial of pump, and there is following shortcoming in above operating process:
1, whole operation process mechanism degree is too low, all adopts manual operations, inefficiency from adding water, imbibition.
We adopt manual operations when 2, adding water, this just must cause and add invisible spectro distilled water and have and have fewly more, causes the waste of distilled water on the one hand, on the other hand since adding distilled water how much differ, cause reaction pearl clean result inconsistent, thereby cause the deviation of testing result.
3, from adding water to the suction manual operations, this is to cause the wash time of reaction pearl inconsistent with regard to the people, thereby influences testing result.
In the present technique field, a kind of bead wahser (patent No. is 93210055.4) was once arranged, this bead wahser is that the reaction tray and the reaction disk cover that utilize the center to have profile hole cooperate with special-shaped rotating middle shaft, or adopt reaction disk cover lid inboard, limit to establish three protruding keys to cooperate with the half-cylindrical recess at reaction tray edge and make, control wash time and number of times with computer.We find that there is distinct disadvantage in this instrument after on probation:
1, in washing process, because the instrument vibration is violent, the reaction bead of putting into each sulculus is shaken outside the groove, and bead is mixed mutually can't be distinguished, thereby can't measurement result.
2, since the reaction pearl in groove, after washing is finished, globule need be transferred in vitro and be measured, this process one be operate more numerous tired.The 2nd, the easy landing of globule causes patient outcomes to fasten one person's story upon another person in transfer process.
The purpose of this utility model is to provide a kind of novel bead wahser, not only make the wash conditions (comprising wash time, number of times and amount of water) of globule remain unanimity, and free adjustment wash conditions according to circumstances, reduce the washing error, make measurement result more stable, increase substantially work efficiency.
The utility model is achieved in that this bead wahser is made up of hydraulic control device, distilled water output unit and water absorber, and hydraulic control device comprises hydraulic controller, oil cylinder, test tube rack fixed mount, fountain head, suction lift.The distilled water output unit comprises distilled water bottle, distilled water rear pump.Water absorber comprises collection bottle, negative pressure pump.Hydraulic controller laterally moves by oil cylinder control test tube rack fixed mount, and vertically move by another oil cylinder control fountain head and power termination, fountain head and suction lift are generally one group, its number is identical with the number of every row's test tube, the delivery outlet of distilled water rear pump is communicated with fountain head by conduit, and suction lift is connected in collection bottle by conduit.
The utility model has the advantages that: 1, automaticity height, add water, absorb water and finish automatically, but wash time and number of times free adjustment; 2, because amount of water and wash time are relatively more consistent, guarantee the stability of measurement result, reduce error; 3, directly washing in vitro of reaction pearl will not reacted pearl and is shifted, has reduced unnecessary trouble.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing 1 is the utility model synoptic diagram.
