Description
Technical field
This utility model relates to injection field, relates in particular to syringe handle end assemble mechanism in a kind of syringe pump, is specially the design of syringe handle end assemble mechanism in the syringe pump of all kinds of syringes of easy assembling.
Background technology
Along with the development of the technology such as Hua Gong ﹑ Yi Liao ﹑ biology in recent years, syringe pump is widely used in above-mentioned field as the accurate and efficient precision pump of a kind of Liang of Dinging ﹑, particularly be accompanied by recent years the development of micro-fluidic chip technology, the detection that increasingization learned in Shi Yan ﹑ biotic experiment and medical procedure is carried out in micro-fluidic chip, and the application of syringe pump is more and more extensive.
The syringe pump major part extensively adopting is at present with a briquetting, syringe handle end to be pressed on syringe pump slide block, then use on key screw briquetting on slide block, although needle handle end can be fixed on slide block like this, but dismantle at every turn and assemble and all want upper and lower screw, cumbersome, once not tight on the screw of some fixing briquetting on the side of slide block, the briquetting easily loosening experimental result that causes is inaccurate.
Application number: WU131524, the applying date: 2013-9-17, denomination of invention are that a kind of syringe pump slide block has proposed a kind of slider designs that is suitable for assembling metal needle handle and plastics needle handle, it is in the time of assembling plastics needle handle, with briquetting, needle handle to be pressed on slide block, this design is suitable for frequently switching the occasion of push-pull mode, need upper and lower screw but load and unload syringe at every turn, cumbersome.
Summary of the invention
The technical problems to be solved in the utility model is: occasion not frequent the switch push-pull mode of syringe pump in some application considered in design of the present utility model, sometimes may need frequently to load and unload syringe occasion.Because metal needle handle end and plastics needle handle end structure size differ greatly, although can by the stopper slot of a large-size of design can fixing metal needle handle again can fixed plastics needle handle, can in the time of assembling, affect instrument performance because size differs greatly.Conventional syringe handle end is circular, and Luer's syringe needle handle end does not generally differ greatly along with the variation of specification of syringe, and general end cake thickness is at 3mm～5mm, diameter 10mm～20mm, and the diameter of needle handle is at 4mm～8mm.Plastic injector needle handle is that tip dimensions differs greatly along with the variation of specification of syringe, and size differs greatly with specification of syringe variation for the diameter of general needle handle and needle handle end cake diameter, but the thickness of needle handle end cake differs very little.Plastics needle handle is generally designed to four fin force structures, and therefore, plastics needle handle is generally larger than metal needle shank diameter.Plastics needle handle end cake thickness is generally at 1.5mm～3mm, diameter 10mm～30mm, and the diameter of needle handle is at 5mm～20mm.
The technical solution adopted in the utility model is: syringe handle end assemble mechanism in a kind of syringe pump, this assemble mechanism comprises pedestal, wiring hole, needle tubing briquetting, needle tubing limited block, left guide post, right guide post, lower guide post, slide block, motor, motor cover plate and encoder cover plate, wiring hole is in the side of pedestal, electric wire connects the motor in pedestal by wiring hole, above motor, there are motor cover plate and encoder cover plate, motor is by lead screw transmission slide block, needle tubing limited block and slide block are the shape of " protruding ", left guide post, right guide post and lower guide post make slide block displacement, slide block comprises the first stopper slot, the second stopper slot, the wherein main spacing plastic injector of the first stopper slot, because the general diameter of plastics needle handle end is larger, thickness is less, the main spacing Luer's syringe of the second stopper slot, the general relative plastic injector diameter of metal needle handle end is less, thickness is larger, for " 1 " shape groove, if constantly switch the occasion of push-and-pull at needs, available screw by " 1 " type groove on slide block, first " U " type open slot and second " U " type open slot, slide block has first " U " type open slot facing to needle tubing limited block one side, after first " U " type open slot, it is the first stopper slot, it after the first stopper slot, is second " U " type open slot, general plastic injector needle handle diameter is larger than Luer's syringe needle handle diameter, if Luer's syringe needle handle stopper slot is left in plastic injector needle handle stopper slot front side, cause some plastic injector to install, after second " U " type open slot, it is the second stopper slot, slide block opposite side has " 1 " shape groove, wherein, the second stopper slot should be opened the side near motor at slide block, on the one hand because metal needle handle end has screw hole, in the situation that needs frequently switch push-pull mode, can be fixed on slide block with key screw needle handle, in the occasion that does not need frequently to switch push-and-pull, only syringe needle handle end need to be put in stopper slot, do not need fixed screw, needle tubing briquetting is used for pushing down needle tubing.
Further, Luer's syringe needle handle stopper slot i.e. the second stopper slot transverse width leaves between 20mm～25mm, longitudinally width is opened between 3mm～5mm, and " U " type open slot of stopper slot front end is generally opened between 8mm～12mm, on stopper slot midline position, have " 1 " type groove, be convenient to fixing syringe simultaneously.
Further, plastics needle handle stopper slot i.e. the first stopper slot transverse width is opened at 25mm～30mm, and longitudinally width is opened between 1.5mm～2.5mm, and " U " type open slot of stopper slot front end is generally opened between 10mm～15mm.
Principle of the present utility model is:
The stopping means that designs respectively two kinds of different size specifications on slide block assembles metal needle handle and plastics needle handle.Further, the stopper slot of metal needle handle on slide block should be opened the side near motor at slide block, on the one hand because metal needle handle end has screw hole, in the situation that needs frequently switch push-pull mode, can be fixed on slide block (in the occasion that does not need frequently to switch push-and-pull with key screw needle handle, only syringe needle handle end need to be put in stopper slot, do not need fixed screw), on the other hand, general plastic injector needle handle diameter is larger than Luer's syringe needle handle diameter, if Luer's syringe needle handle stopper slot is left in plastic injector needle handle stopper slot front side, cause some plastic injector to install.Further, the general transverse width of Luer's syringe needle handle stopper slot leaves between 20mm～25mm, longitudinally width is opened between 3mm～5mm, and " U " type open slot of stopper slot front end is generally opened between 8mm～12mm (this groove is in order to allow Luer's syringe needle handle put in).On stopper slot midline position, have " 1 " type groove, be convenient to fixing syringe simultaneously.Further, the general transverse width of plastics needle handle stopper slot is opened at 25mm～30mm, and longitudinally width is opened between 1.5mm～2.5mm, and " U " type open slot of stopper slot front end is generally opened between 10mm～15mm.
The utility model has the advantage of:
(1), frequently change the occasion of syringe at needs, handling syringe is more convenient;
(2), at syringe pump singly to push away or single pull-mode when work, only injector handle need to be snapped in after stopper slot, through simple pretension, can normally use;
(3), use the occasion of push away-pull-mode at needs, can Luer's syringe handle be fixed on slide block by " 1 " type groove (153) with hand tighten screw easily;
(4), there are stopper slot 1 and stopper slot 2 combinations of the larger scope of application, the handle of conventional syringe all can be directly spacing on the market.
