Description
Technical field
The utility model is related to technical field of medical equipment more particularly to a kind of thrombelastogram instrument transmission mechanisms.
Background technology
Thrombelastogram instrument (Thrombelastography, TEG) is that one kind monitoring blood coagulation from entire dynamic process
The analyzer of journey.Thrombelastogram instrument is widely used in blood transfusion in clinical guidance art, perioperative (is to be directed to need surgical operation disease
Processing procedure a professional term, including it is preoperative, in art and postoperative total segment time) monitoring coagulation function, simultaneously be also
Advanced country carries out the important tool of blood product management in the world, and the equipment is used in guide transfusing blood.Thrombelastogram instrument can
Carry out the dynamic analysis of the processes such as coagulation factor activation, platelet aggregation, fibrinolysis.The original substantially of thrombelastogram instrument
Reason is：Motor drive carries test cup (such as 4 degree 45 points) and period (such as 10 seconds) rotation at a certain angle of blood specimen, once
Thrombosis, the metal probe being placed in blood specimen detection cup are acted on by the shearing stress of sample, are rotated about therewith.Gold
The turn for belonging to probe is incuded by contactless angle turn sensor (such as inductance type angular transducer), is converted into electricity and gives place
Device processing is managed, coagulation curve is just formed.Above-mentioned metal probe hangs on a torsion pendency silk, in metal probe turn process
In, torsion pendency silk needs to provide a kind of progressive torsional resistance, to resist the torque from metal probe.Silk dangle in thrombus bullet
Try hard to play in instrument to key effect, the too big or too small pendency silk of uneven torque, torque coefficient cannot all obtain correctly
Coagulation curve.
Pendency silk in thrombus elastic force inspection plotting apparatus is usually made of the torsion wire of the suspension connector of upper part and lower part, is hanged
Threaded Connector Coupling is fixed on fixed base, torsion wire lower end suspension sensing column.It is larger (such as to sense column diameter：10 times of torsion wire diameter).In order to
Ensure pendency silk and sense the concentric rate of column, to be inserted into sensing column centre bore, the mode of additional lock screw occlusion connects pendency silk
It connects.The torque sensor being made of pendency silk and sensing column is in pendency state.A test cup is set in sensing column lower end, is contained in cup a certain amount of
Sample (liquid) is immersed without being contacted with wall of cup or bottom of a cup in sample to be tested, cylinder lower end.When driving mechanism makes test cup around sensing
Column is at a certain angle (such as：4 degree 45 points) periodically (such as：10 seconds) rotation when, due to the toughness of sample, test sample will drive
Sense column rotation, at this point, the torsion wire that suspended on sensing column need to provide a kind of suitable size, uniformly progressive resistance to be to resist
Torque from sensing column.By additional non-contact rotational angle detector, the resiliency characteristics of sample can be detected.
From detection process as can be seen that being a process with high accuracy by torsion wire detection, detection process precision is not achieved, Huo Zheshou
All it is to play influence to obtaining accurate detection result to influence.
In the prior art, the rotation of torsion wire drives detector to carry out by cam mechanism drive link, then by connecting rod
Experiment.This has resulted in corresponding driving part and transmission parts need good machining accuracy and installation accuracy, while right
Stability of the corresponding component in real-world operation also has very high requirement, and it is high to be bound to cause production cost.In addition, existing apparatus
The rotation of cam mechanism progress many times is needed in actual use, and cam is caused to generate abrasion as access times increase, into
And running precision is seriously affected, it causes a devastating effect to testing result.
