Description
Technical field
This utility model relates to technical field of medical equipment, is specially a kind of automated injection device.
Background technology
Drug injection is one for the treatment of means commonly used clinically.Traditional manual injection length consuming time, waste of manpower, be difficult to control, injection effect is not good.Mostly there is the problem that design is complicated, cost of manufacture is large in the automatic injection product now occurred on the market.
Summary of the invention
For the problems referred to above, this utility model provides a kind of and replaces the middle pushing-type automated injection device artificial, simplicity of design, cost of manufacture are little, injection effect is good.
The technical scheme that this utility model adopts for its technical problem of solution is:
Middle pushing-type automated injection device, comprising: base; For the push rod fixed block of fixing syringe push rod, push rod fixed block is fixed on base; For the movable cushion cap of fixing syringe barrel, movable cushion cap is arranged on the side of push rod fixed block and can relatively moves around by push rod fixed block; For the driving mechanism driving movable cushion cap to move around, driving mechanism is fixed on base, and movable cushion cap is installed on driving mechanism.
Wherein, described driving mechanism comprises: be fixed on the first fixed block on base and the second fixed block, and the first fixed block and the second fixed block relative spacing are arranged; Be arranged on the screw rod between the first fixed block and the second fixed block; Be arranged on the motor for drive screw turns on the first fixed block; Be fixed on guide rod between the first fixed block and the second fixed block and parallel with screw rod, guide rod surface smoothing; Nut slider, described nut slider is provided with the screw corresponding with screw rod and the guide hole corresponding with guide rod cross sectional shape, and nut slider is installed on screw rod and guide rod respectively by screw and guide hole; Described movable cushion cap is fixed on nut slider.
Described guide rod is configured to be wrapped in the arc list structure being provided with opening outside screw rod, below screw rod, and it is outer and extend to guide rod inside from opening and be threaded onto screw rod again that nut slider is wrapped in guide rod.
The beneficial effects of the utility model are: when this utility model uses, the push rod of syringe is fixed on push rod fixed block, cylindrical shell is then fixed on movable cushion cap, movable cushion cap relative push rod fixed block under the effect of driving mechanism is subjected to displacement, syringe and push rod is made also relative displacement to occur, when syringe is when push rod is close, the injection of syringe inside is outwards extruded by push rod, namely achieves automatic injection process.Its structural principle is simple, and cost of manufacture is low, and accurately can control reservoir quantity by the stroke of driving mechanisms control activity cushion cap, injection process does not need artificial participation substantially.Especially, when driving mechanism to be made up of guide rod and screw rod etc. and guide rod is configured to arc strip encapsulated by structures when screw rod is outside, the monnolithic case of device is more attractive in appearance compacter, and barrier propterty is greatly enhanced.
Accompanying drawing explanation
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of a kind of embodiment of this utility model;
Fig. 2 is the section mounting structure schematic diagram of the guide rod of the another kind of embodiment of this utility model, screw rod, nut slider and movable cushion cap part.
Detailed description of the invention
With reference to Fig. 1, this utility model is made primarily of base 1, push rod fixed block 2, movable cushion cap 3 and driving mechanism etc., shown in Fig. 1 is the basic structure that can realize this utility model function, when embody rule, structure in figure can carry out relevant configuration and optimization, thus forms the product of an overall appearance.
Driving mechanism produces controllable displacement for driving movable cushion cap.As preferably, as shown in this embodiment, driving mechanism is made up of the first fixed block 4, second fixed block 5, screw rod 6, guide rod 7, motor 8 and nut slider 9 etc.Wherein the first fixed block 4 and the second fixed block 6 are fixed on base 1, and both relative spacings are arranged.Screw rod 6 is installed between two fixed blocks, and it can rotate, and is driven by the motor 8 be arranged on the first fixed block 4.Guide rod 7 is fixed between two fixed blocks, parallel with screw rod 6, guide rod 7 surface smoothing, and the quantity of guide rod 7 can be 1, more than 2 or 2.Nut slider 9 is as the support member of movable cushion cap 3, and it is provided with the screw corresponding with screw rod 6 and the guide hole corresponding with guide rod 7 cross sectional shape, and nut slider 9 is installed on screw rod 6 and guide rod 7 respectively by screw and guide hole.
Push rod fixed block 2 is fixed on base 1, and fixing mode can directly be fixed, also can by be arranged in other structures thus to be formed and the relatively-stationary relation of base 1.As shown in this embodiment, push rod fixed block 2 is fixed on the second fixed block 5.
As shown in Figure 1, during utility model works, on syringe A placement activity cushion cap 3, movable cushion cap 3 is generally provided with pressure handle syringe is maintained static, the push rod of syringe afterbody sticks on push rod fixed block 2, motor 8 drives screw rod 6 to rotate, and screw rod 6 is moved by nut slider 9 drive activity cushion cap 3, realizes the injection of syringe.The effect of guide rod 7 is auxiliary hold-down nut slide blocks 9, plays the effect of guiding and increase activity cushion cap 3 stationarity.
In the embodiment in figure 1, guide rod 7 is circular columns strip.In order to make the guide effect of guide rod 7 better and play other extra effects, guide rod 7 preferably adopts structure as shown in Figure 2 to realize, in the present embodiment, guide rod 7 is configured to be wrapped in outside screw rod 6, below screw rod 6, is provided with the arc list structure of opening, and it is outer and extend to guide rod 7 inside from opening and be threaded onto screw rod 6 again that nut slider 9 is wrapped in guide rod.Guide rod guide effect in the present embodiment strengthens, and in addition, this guide rod can also play the effect of hiding screw rod 6, effectively avoids outside pollutant to drop on screw rod, guarantees that injection device operation duration is normal.In addition, because screw rod is hidden, therefore the overall appearance of device is improved.
Embodiment of the present utility model is not restricted to the described embodiments, as long as it reaches technique effect of the present utility model with substantially identical means, all should belong to protection domain of the present utility model.
