Description
Technical field
The application belongs to technical field of medical instruments, is specifically related to a kind of analytical instrument special-purpose thermal insulation syringe.
Background technology
In medical science detects, in the course of work of particularly analytical instrument, need reagent and the sample of suction difference amount, realize this function at present, mainly rely on traditional syringe to realize.Existing commercial syringe, owing to usually using softer encapsulant (as teflon) as piston head to realize sealing and the suction sample process of syringe, after operation a period of time, piston head just there will be wearing and tearing in various degree, light then cause application of sample forbidden, heavy then cause leakage, so must make regular check on and safeguard.And when analytical instrument Water demand has the liquid of temperature, the feel temperature of operating personnel can affect the accuracy of measurement.
Summary of the invention
Goal of the invention: for deficiency of the prior art, the object of the application is to provide a kind of analytical instrument special-purpose thermal insulation syringe, makes it not only wear and tear low but also measurement result is more accurate.
Technical scheme: in order to solve deficiency of the prior art, the application adopts following technical scheme:
A kind of analytical instrument special-purpose thermal insulation syringe, comprise main body, water inlet, water delivering orifice, piston rod, end cap, O-ring seal and vacuum layer, in described main body, be provided with inner chamber, described end cap all has setting in the both sides of main body; Described piston rod is fixed on one end of main body by end cap and runs through in the inner chamber of main body, and described end cap is provided with O-ring seal; Be provided with the water delivering orifice of fitting piston bar use at the other end of described main body, be provided with the water inlet that fitting piston bar uses in the bottom of described main body; Wherein, water inlet and water delivering orifice all communicate with the inner chamber of main body; Vacuum layer is provided with in the periphery of described main body.
Described O-ring seal is the O-ring seal of resilient material, and described piston rod is the piston rod of ceramic rod or stainless steel material.
The cross sectional radius of described piston rod is less than the cross sectional radius of described body lumen.
Water intaking valve is provided with in described water inlet.
Beneficial effect: compared with prior art, the analytical instrument special-purpose thermal insulation syringe of the application, by arranging vacuum layer, is used for being incubated, prevents the feel temperature of operating personnel from affecting testing result, improve accuracy of detection; Only coordinated with O-ring seal by piston rod, and the direct contact friction of inwall that is not direct and main body, thus avoid the wearing and tearing of piston rod, leakage can not be produced, therefore do not need to safeguard; This syringe extensively can be suitable for Biochemical Analyzer, immunity analysis instrument, blood coagulation analyzer, blomelicalbloodgasandelectrolrteanalyzers, the luminous liquid sucking-discharging system detecting other in-vitro diagnosis equipment such as analyser, has good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of analytical instrument special-purpose thermal insulation syringe.
Embodiment
Below in conjunction with the drawings and specific embodiments, the application is described further.
A kind of analytical instrument special-purpose thermal insulation syringe, comprise main body 1, water inlet 2, water delivering orifice 3, piston rod 4, end cap 5, O-ring seal 6 and vacuum layer 7, in main body 1, be provided with inner chamber, end cap 5 all has setting in the both sides of main body 1; Piston rod 4 is fixed on one end of main body 1 by end cap 5 and runs through in the inner chamber of main body 1, and end cap 5 is provided with O-ring seal 6; Be provided with the water delivering orifice 3 of fitting piston bar 4 use at the other end of main body 1, be provided with the water inlet 2 that fitting piston bar 4 uses in the bottom of main body 1, wherein, water inlet 2 and water delivering orifice 3 all communicate with the inner chamber of main body 1; Vacuum layer 7 is provided with in the periphery of main body 1.O-ring seal 6 is the O-ring seal 6 of resilient material, and piston rod 4 is the piston rod 4 of ceramic rod or stainless steel material.The cross sectional radius of piston rod 4 is less than the cross sectional radius of described main body 1 inner chamber; At water inlet 2, place is provided with water intaking valve.
The course of work: water inlet 2 connects water intaking valve, water delivering orifice 3 is connected with the sample needle of analytical instrument.During liquid sucking-discharging, close water intaking valve, piston rod 4 moves outside main body 1, cavity volume is increased, just liquid is sucked sample needle; Piston rod 4 moves in described main body 1, cavity volume is reduced, just liquid is discharged sample needle, complete application of sample work.General, often complete an application of sample job, all need to clean sample needle, now, open water intaking valve, cleaning fluid just can enter described main body 1 inner chamber from water inlet 2, then passes to sample needle from water delivering orifice 3, thus completes sample needle cleaning; The cross sectional radius of piston rod 4 is less than the cross sectional radius of described main body l inner chamber, moving up and down by piston rod 4 during work, changes the volume that piston rod 4 takies at body lumen, reaches and meet the high object of application of sample precision; End cap 5 is all set in the both sides of main body 1, convenient installation; Be provided with vacuum layer 7 in the periphery of main body 1, be used for being incubated, prevent the feel temperature of operating personnel from affecting testing result, improve accuracy of detection.
This analytical instrument special-purpose thermal insulation syringe, by arranging vacuum layer 7, is used for being incubated, prevents the feel temperature of operating personnel from affecting testing result, improve accuracy of detection; Only coordinated with O-ring seal 6 by piston rod 4, and the direct contact friction of inwall that is not direct and main body 1, thus avoid the wearing and tearing of piston rod 4, leakage can not be produced, therefore do not need to safeguard; Accuracy guarantee is the cylindrical of piston rod 4, and difficulty of processing will ensure the difficulty of processing of precision injection device inwall well below existing traditional inner circle, thus can ensure precision and handling ease, and therefore processing cost is lower; Use high-precision ceramic rod or stainless steel bar as syringe piston rod 4, because material height is wear-resisting, so really can accomplish non-maintaining within the product time limit in serviceable life.This syringe extensively can be suitable for Biochemical Analyzer, immunity analysis instrument, blood coagulation analyzer, blomelicalbloodgasandelectrolrteanalyzers, the luminous liquid sucking-discharging system detecting other in-vitro diagnosis equipment such as analyser.
