Description
Technical field
The present invention relates to a kind of sample needle anticollision device, collision-prevention device of in-vitro diagnosis equipment, belong to technical field of medical instruments.
Background technology
The most commonly used diagnostic method in-vitro diagnosis of medical domain at present, refer to gather body fluid, the row of human body
Let out thing, secretions carry out chemical composition or chemical reaction analysis, thus judging human lesion.Such as chemiluminometry, point
Son diagnosis.These diagnostic methods, are all loaded using automatically or semi-automatically instrument, analysis, and provide diagnosis report.
The sample adding device of this quasi-instrument, needs to be equipped with disposable sample injector or reusable sample needle.Disposably
Sample injector integrated cost is higher, can increase the cost of single inspection project, for lower-cost inspection project, disposable sample-adding
Device is extremely uneconomical.Reusable sample needle cost per unit is higher, and program of changing is complicated, and there is the wind of biochemical pollution
Danger.In the case that exception in instrument, there is the risk clashing into other positions of instrument in sample needle, causes to shut down and damages；Very
As for biochemical pollution.So in the instrument diagnosing in vitro, needing to consider that protection sample needle, in the case of instrument exception, avoids
Damage, it is to avoid loss, reduce the risk of biochemical pollution.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As illustrated, a kind of sample needle anticollision device, collision-prevention device of in-vitro diagnosis equipment of the present invention, including sample needle 1 and driving dress
Put（Not shown）, also include the level sensor seat 2 being connected positioned at sample needle 1 top and with sample needle 1, described driving means
（Not shown）Drive a tooth bar pipe 5, described tooth bar pipe 5 connects a contact element 3, is provided with and leads in described level sensor seat 2
To set 4, described tooth bar pipe 5 can move in fairlead 4, is provided with compression bullet between described tooth bar pipe 5 and level sensor seat 2
Spring 6, is in compressive state after installation.Described tooth bar pipe 5 is machined with the kidney slot 7 of above-below direction above, and a latch 8 is screwed in
On level sensor seat 2, and its front end tangles the lower end of tooth bar pipe 5 kidney slot 7.Described contact element 3 is pacified by contact element
Dress seat 9 is arranged on above level sensor 2, and described contact element mounting seat 9 is electrically non-conductive material.Described level sensor seat 2
Processed by conducting metal, it is with whole instrument in electrical connection " altogether ".
Latch 8 is prevented from fairlead 4 and is mutually rotated with tooth bar pipe 5, and is prevented from compression spring 6 in pressure
Under contracting state, tooth bar pipe 5 is separated with level sensor seat 2.
Described contact element mounting seat 9 is electrically non-conductive material, so that under protection instrument normal condition, contact element 3 and instrument
There is not electrical communication in device.
In instrument normal work, contact element 3 does not contact level sensor seat 2 to the anticollision device, collision-prevention device of the present invention, does not believe
Number；Once generation striker, level sensor seat 2 will move upwards along tooth bar pipe 5, then contact contact element 3, at this moment contact
Element 3 and instrument " " connect, thus providing signal to control system.Control system makes protection act immediately, effectively keeps away
Exempt from instrument sample needle 1 to damage.Level sensor seat 2, upwards in motor process, is compressing compression spring 6 always；After instrument recovers,
Compression spring 6 is pushed to level sensor seat 2 bottom of tooth bar pipe 5 again, makes contact element 3 and level sensor seat 2
Disengage.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
For member, on the premise of without departing from the technology of the present invention principle, some improvement can also be made and deform, these improve and deform
Also should be regarded as protection scope of the present invention.
