The clamping mechanism of the injection syringe push head comprises a push head front shell, a push head rear shell and a guide rod. A dialing rod is arranged on the outer side of the push head rear shell, the dialing rod is connected with a dialing gear between the push head front shell and the push head rear shell, the dialing gear is meshed with a drive cam which is fixed through a positioning pin, the drive cam is matched with a sliding block which is matched with a left rack and a right rack, the left rack and the right rack are simultaneously matched with clamping gears on the two sides, and the clamping gears are respectively connected with an injection syringe clamping position on the outer side of the push head front shell. The clamping mechanism of the injection syringe push head has the advantages that a pressure sensor is pushed into the push head and directly acts on the position of the injection syringe push head, the acting force of an injection syringe to a pump is truly fed back, and pressure is pushed and injected; the link of probable errors is reduced, and product performance is stabilized.
Description
Technical field
This utility model relates to a kind of micro-injection pump technical field, especially a kind of syringe clamping device of cutting somebody's hair.
Background technology
Micro-injection pump is a kind of instrument that carries out for a long time even micro-injection often using in clinical treatment and life science.This instrument is mainly used in arteriovenous transfusion, blood transfusion, shock treatment, enteral pipe and narcotic injection etc., also can be used in the micro-injection of anticoagulant and other special valuable medicines in the wound rescues such as extruding simultaneously.Reasonably use micro-injection pump, can alleviate many made work amounts, also facilitate control accuracy, reach desirable therapeutic effect simultaneously.
Traditional design pressure transducer is arranged on interiors of products, and the pressure of measuring whole mechanical pushing structure changes, but due to mechanical wear, pressure feedback also can change with the aggravation of wearing and tearing, finally affects the accuracy of the pressure data that terminal obtains.
Summary of the invention
This utility model will solve the shortcoming of above-mentioned prior art, provides a kind of pressure transducer to act directly on the syringe syringe at the position clamping device of cutting somebody's hair of cutting somebody's hair.
This utility model solves the technical scheme that its technical problem adopts: this syringe clamping device of cutting somebody's hair, comprise the fore shell of cutting somebody's hair, cut somebody's hair back cover and guide post, cut somebody's hair back cover outside is provided with driving lever, driving lever and the fore shell of cutting somebody's hair, the handsetting gear of cutting somebody's hair between back cover are connected, handsetting gear with by the fixing driving cam of alignment pin, be meshed, driving cam matches with slide block, slide block matches with left tooth bar, right tooth bar, left tooth bar and right tooth bar coordinate with the screens gear of both sides simultaneously, and screens gear is connected with the syringe screens in the fore shell outside of cutting somebody's hair respectively.
As preferably, below described left tooth bar and right tooth bar, be provided with return spring.
As preferably, above described left tooth bar and right tooth bar, be provided with optocoupler sensor.
As preferably, described guide post is connected with sensor holder, and sensor holder is provided with the pressure transducer coordinating with syringe piston.
As preferably, described syringe screens and cut somebody's hair and be provided with sealing ring between fore shell.
The effect that utility model is useful is: this utility model is put into pressure transducer to cut somebody's hair, and acts directly on the syringe position of cutting somebody's hair, and truly feeds back the active force of syringe to pump, inject pressure, the design's advantage, has reduced the link that may cause error, has stablized properties of product.
Accompanying drawing explanation
Fig. 1 is decomposition texture schematic diagram of the present utility model;
Fig. 2 is overall structure schematic diagram of the present utility model;
Fig. 3 is result of use figure of the present utility model;
Description of reference numerals: the fore shell 1 of cutting somebody's hair, screens gear 2, left tooth bar 3, return spring 4, sensor holder 5, right tooth bar 6, the back cover 7 of cutting somebody's hair, driving lever 8, slide block 9, optocoupler sensor 10, driving cam 11, handsetting gear 12, alignment pin 13, guide post 14, sealing ring 15, pressure transducer 16, syringe screens 17.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: as Fig. 1, 2, a kind of syringe clamping device of cutting somebody's hair, comprise the fore shell 1 of cutting somebody's hair, cut somebody's hair back cover 7 and guide post 14, back cover 7 outsides of cutting somebody's hair are provided with driving lever 8, driving lever 8 and the fore shell 1 of cutting somebody's hair, the handsetting gear 12 of cutting somebody's hair between back cover 7 is connected, handsetting gear 12 with by the fixing driving cam 11 of alignment pin 13, be meshed, driving cam 11 matches with slide block 9, slide block 9 and left tooth bar 3, right tooth bar 6 matches, left tooth bar 3 and right tooth bar 6 coordinate with the screens gear 2 of both sides simultaneously, screens gear 2 is connected with the syringe screens 17 in fore shell 1 outside of cutting somebody's hair respectively.Left tooth bar 3 and right tooth bar 6 belows are provided with return spring 4, and side is provided with optocoupler sensor 10.Guide post 14 is connected with sensor holder 5, and sensor holder 5 is provided with the pressure transducer 16 coordinating with syringe piston.Syringe screens 17 and cut somebody's hair and be provided with sealing ring 15 between fore shell 1.
When medical personnel press driving lever 8 downwards with thumb, driving lever 8 drives fluctuation gear 12, and fluctuation gear 12 promotes slide block 9, and sliding 9 promote left tooth bar 3 and right tooth bar 6 simultaneously.When left tooth bar 3 and right tooth bar 6 move up simultaneously, optocoupler sensor 10 provides signal, and syringe pump master control borad is received signal, determines that syringe screens normally moves.As two optocouplers do not provide signal simultaneously, syringe pump will provide warning, quit work.Left tooth bar 3 and right tooth bar 6 drive screens gear 2 simultaneously, and screens gear 2 is connected with syringe screens 17.When medical personnel press driving lever 8 certain angle downwards with thumb, the corresponding opened with certain angle of syringe screens 17, thus together with spacing with the fore shell 1 of cutting somebody's hair, block syringe, as shown in Figure 3.Medical personnel are different according to using specification of syringe, and the angle of pressing 8. driving levers is different, drives the difference of syringe screens 17 opening angles, thereby block the syringe of different size.
When cutting somebody's hair, clamp syringe, during with different rates infused drug, pressure transducer 16 contacts with syringe piston, and infusion pressure value is fed back to syringe pump master control borad constantly.
In addition to the implementation, this utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of this utility model requirement.
