Syringe syringe needle extracting apparatusTechnical field
Syringe syringe needle extracting apparatus, belongs to medical equipment apparatus field.
Background technology
Syringe syringe needle is must to abandon to avoid reusing to cause infection after using, being all manually extract, workload is big, and easily hinders hands in the past, occurred in that the device of syringe needle extracted by machinery later, this device is rotated against by roller thus being extracted from needle tubing by syringe needle, but syringe needle is long, and needle surface is smooth, the little syringe needle skidding of power of roller clamping syringe needle, the big then easy bending of syringe needle, causes syringe needle in the process extracted easily to be stuck between roller, job insecurity.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, easy to operate, reliable operation syringe syringe needle extracting apparatus, it is possible to effectively prevent syringe needle in the process extract syringe needle from skidding or bending.
This utility model solves its technical problem and be the technical scheme is that this syringe syringe needle extracting apparatus, including casing and disposable box, disposable box is fixed on casing bottom, disposable box upper end connects with casing, casing front end offers syringe needle insertion groove, it is characterized in that: in the casing on rear side of syringe needle insertion groove, be provided with two roller set side by side, each roller set includes upper and lower two rollers in relative rotation, the surface of each roller is equipped with layer of silica gel, the layer of silica gel surface of at least one roller offers multiple groove, and groove is parallel to the axis of roller.
Preferably, it is equipped with Magnet layer in described disposable box.Magnet layer adsorbs the syringe needle dropped, it is simple to transfer is filled with the disposable box of syringe needle.
Preferably, the layer of silica gel smooth surface near the roller of a roller set of syringe needle insertion groove is arranged, and the layer of silica gel surface of the roller of another roller set is provided with described groove.Roller set near syringe needle insertion groove is used for leading, it is provided that less frictional force, and the roller set away from syringe needle insertion groove provides bigger frictional force to drive syringe needle to move.
Preferably, being provided with a vertical dividing plate in the middle part of described internal side of shell, roller set is positioned on front side of dividing plate, offers syringe needle pilot hole in the middle part of dividing plate.Further prevent syringe needle generation bending, prevent syringe needle from falling to below roller, it is ensured that roller normally rotates simultaneously.
Preferably, two roller close contacts in described roller set, one of them roller connects motor and as drivewheel.Reduce motor consumption, reduce cost.
Preferably, in described roller set, two rollers are connected to the motor driving its rotation.
Preferably, the bottom of described casing is provided with the chute of clamping disposable box.Disposable box is easy to connect, is easy to be taken off by chute, seals up for safekeeping, focuses on after disposable box is filled.
Compared with prior art, the technique scheme of this syringe syringe needle extracting apparatus is had the beneficial effect that to insert in casing by syringe needle from syringe needle insertion groove, two roller set rotate and drive syringe needle to move to internal side of shell, one roller set can as guide roller, one roller set applies frictional force and drives syringe needle to move, can either effectively prevent syringe needle from skidding, can effectively prevent again syringe needle generation bending, the layer of silica gel of roller surface then can increase the frictional force of roller and syringe needle, and layer of silica gel can deform at groove in the cephalomotor process of pin, it is adapted to the syringe needle of different-diameter.

Detailed description of the invention
Fig. 1 ~ 2 are the most preferred embodiments of this syringe syringe needle extracting apparatus, are described further below in conjunction with 1 ~ 2 pair of this utility model of accompanying drawing.
nullWith reference to Fig. 1 ~ 2，This syringe syringe needle extracting apparatus，Including casing 5 and disposable box 8，Disposable box 8 is fixed on casing 5 bottom，Disposable box 8 upper end connects with casing 5，Casing 5 front end offers syringe needle insertion groove 2，Two roller set side by side it are provided with in casing 5 on rear side of syringe needle insertion groove 2，Each roller set includes upper and lower two roller 4 in relative rotation，The surface of each roller 4 is equipped with layer of silica gel 10，Layer of silica gel 10 surface of at least one roller 4 offers multiple groove 11，Groove 11 is parallel to the axis of roller 4，Syringe needle 1 is inserted in casing 5 from syringe needle insertion groove 2，Two roller set rotate and drive syringe needle 1 to casing 5 medial movement，One roller set can as guide roller 4，One roller set applies frictional force and drives syringe needle 1 to move，Can either effectively prevent syringe needle 1 from skidding，Can effectively prevent again syringe needle 1 from bending occurring，The layer of silica gel 10 on roller 4 surface then can increase the frictional force of roller 4 and syringe needle 1，And layer of silica gel 10 can deform at groove 11 place in the process of syringe needle 1 motion，It is adapted to the syringe needle 1 of different-diameter.
Concrete, the front end of casing 5 is plastic dam 3, and syringe needle insertion groove 2 is opened in the middle part of plastic dam 3, the shape of syringe needle insertion groove 2 is identical with the shape of needle holder, and being inserted after in syringe needle insertion groove 2 by syringe needle 1, needle holder is fixed in syringe needle insertion groove 2, fixation, work safety.
Arrange near layer of silica gel 10 smooth surface of the roller 4 of a roller set of syringe needle insertion groove 2 in the present embodiment, layer of silica gel 10 surface of the roller 4 of another roller set is provided with groove 11, roller 4 above is as directive wheel, and roller 4 below is as the power wheel applying frictional force dragging syringe needle 1.This utility model can also will be close to the layer of silica gel 10 surface configuration groove 11 of the roller 4 of a roller set of syringe needle insertion groove 2, and layer of silica gel 10 smooth surface away from the roller 4 of a roller set of syringe needle insertion groove 2 is arranged.In roller set, two rollers 4 are in close contact, and one of them roller 4 connects motor, and as drivewheel, another roller 4, as driven pulley, so can reduce the quantity of motor, reduces cost.Motor used is conventional design.
Casing 5 middle inside is provided with a vertical dividing plate 6, and roller set is positioned on front side of dividing plate 6, offers syringe needle pilot hole 7 in the middle part of dividing plate 6, it is possible to prevent syringe needle 1 from dropping below roller 4, it is ensured that the normal operation of roller 4.Being equipped with Magnet layer 9 in disposable box 8, the syringe needle 1 that Magnet layer will fall off adsorbs, it is simple to subsequent treatment.In the present embodiment, being provided with the chute of clamping disposable box 8 in the bottom of casing 5, the upside of disposable box 8 is correspondingly provided with the horizontal flanging inserting chute, disposable box 8 and casing 5 grafting, easy to connect, it is simple to change disposable box 8.
Being above preferred embodiment of the present utility model, in this utility model, in roller set, two rollers 4 can also connect the motor driving its rotation respectively, it is also possible to synchronizes to drive four rolling 4 to rotate by synchronous pulley.
The above, it it is only preferred embodiment of the present utility model, being not the restriction that this utility model is made other form, any those skilled in the art are changed or are modified as the Equivalent embodiments of equivalent variations possibly also with the technology contents of the disclosure above.But every without departing from technical solutions of the utility model content, any simple modification, equivalent variations and remodeling above example made according to technical spirit of the present utility model, still fall within the protection domain of technical solutions of the utility model.
