Abstract
The invention discloses a sampling probe anti-collision device for in-vitro diagnosis equipment. The device comprises a sampling probe, a drive device and a contact switch which is positioned above the sampling probe and connected with the sampling probe, wherein the drive device is used for driving a round tube; the round tube is connected with the sampling probe by virtue of a spring, and is connected with a contact element. In the instrument running process, the sampling probe anti-collision device rebounds by utilizing a guiding device and sends out a signal to a control system of the instrument when a sampling probe is contacted with other parts of the instrument, the control system of the instrument stops running to protect the sampling probe, and the device is re-started by virtue of the spring to protect the sampling probe after abnormality of the instrument is recovered, so that the sampling probe is protected from breakage, and downtime loss, instrument maintenance cost and biochemical pollution can be reduced.
Description
Technical field
The present invention relates to a kind of sample needle collision avoidance system of in-vitro diagnosis equipment, belong to technical field of medical instruments.
Background technology
The diagnostic method that current medical domain the most generally uses---in-vitro diagnosis, refers to that the body fluid of collection human body, excreta, secretion carry out chemical composition or chemical reaction analysis, thus judges human lesion.As chemiluminometry, molecular diagnosis.These diagnostic methods, all adopt automatically or semi-automated instrument carries out application of sample, analyze, and provide diagnosis report.
The sample adding device of this quasi-instrument, needs to be equipped with disposable sample injector or reusable sample needle.Disposable sample injector integrated cost is higher, can increase the cost of single Interventions Requested, and for lower-cost Interventions Requested, disposable sample injector is very uneconomical.Reusable sample needle cost per unit is higher, changes program complicated, and there is the risk of biochemical pollution.When instrument occurs abnormal, there is the risk of clashing into other positions of instrument in sample needle, causes and shut down and damage; Biochemical pollution even.So in the instrument diagnosed in vitro, need to consider that protection sample needle is when instrument exception, avoids damaging, avoids loss, reduce the risk of biochemical pollution.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of sample needle collision avoidance system of in-vitro diagnosis equipment is provided.
The present invention is achieved through the following technical solutions:
A kind of sample needle collision avoidance system of in-vitro diagnosis equipment, comprise sample needle and drive unit, also comprise the level sensor seat being positioned at and being connected above sample needle and with sample needle, described drive unit drives a pipe, described pipe is connected with level sensor seat by spring, described pipe connects a contact element, and be provided with orienting sleeve in described level sensor seat, described pipe can move up and down in orienting sleeve.
The sample needle collision avoidance system of described a kind of in-vitro diagnosis equipment, described pipe is tooth bar pipe.
The sample needle collision avoidance system of described a kind of in-vitro diagnosis equipment, is processed with the kidney slot of above-below direction above described tooth bar pipe.
The sample needle collision avoidance system of described a kind of in-vitro diagnosis equipment, also comprises stop pin, and described stop pin is screwed on level sensor seat, and its front end tangles the lower end of tooth bar pipe kidney slot.
The sample needle collision avoidance system of described a kind of in-vitro diagnosis equipment, described contact element is arranged on above level sensor by contact element mount pad, and described contact element mount pad is electrically non-conductive material.
The sample needle collision avoidance system of described a kind of in-vitro diagnosis equipment, described level sensor seat is processed by conducting metal.
The beneficial effect that the present invention reaches:
Sample needle collision avoidance system of the present invention is in instrument runs, once there are other parts of sampling probe contact instrument, this device can utilize guide piece resilience, provides the control system of signal to instrument simultaneously.Instrumentation control system meeting stop motion, protection sample needle.After instrument abnormal restoring, spring can start this device again, protection sampling probe.Sampling probe can be protected to avoid damaging, reduce shutdown loss, instrument maintenance cost and biochemical pollution.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in the figure, the sample needle collision avoidance system of a kind of in-vitro diagnosis equipment of the present invention, comprise sample needle 1 and drive unit (not shown), also comprise the level sensor seat 2 being positioned at and being connected above sample needle 1 and with sample needle 1, described drive unit (not shown) drives a tooth bar pipe 5, described tooth bar pipe 5 connects a contact element 3, in described level sensor seat 2, orienting sleeve 4 is installed, described tooth bar pipe 5 can move in orienting sleeve 4, between described tooth bar pipe 5 and level sensor seat 2, Compress Spring 6 is installed, after installation, is namely in compressive state.Kidney slot 7, one stop pin 8 that described tooth bar pipe 5 is processed with above-below direction is above screwed 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 arranged on above level sensor 2 by contact element mount pad 9, and described contact element mount pad 9 is electrically non-conductive material.Described level sensor seat 2 is processed by conducting metal, itself and whole instrument on being electrically connected " altogether ".
Stop pin 8 can prevent orienting sleeve 4 and tooth bar pipe 5 from mutually rotating, and Compress Spring 6 can be prevented to be separated with level sensor seat 2 by tooth bar pipe 5 under compression.
Described contact element mount pad 9 is electrically non-conductive material, so that under protecting instrument normal condition, contact element 3 and instrument electrical communication do not occur.
Collision avoidance system of the present invention is when instrument normally works, and contact element 3 is Fluid Contacting location probe seat 2 not, does not have signal; Once generation striker, level sensor seat 2 will move upward along tooth bar pipe 5, then contact contact element 3, at this moment contact element 3 and instrument " " connect, thus provide signal to control system.Control system makes protection act immediately, effectively avoids instrument sample needle 1 to damage.Level sensor seat 2 moves upward in process, is compressing Compress Spring 6 always; After instrument recovers, Compress Spring 6 will push level sensor seat 2 to the bottom of tooth bar pipe 5 again, and contact element 3 and level sensor seat 2 are disengaged.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
