Description
Technical field
This utility model relates to a kind of ophthalmosyringe, especially relate to a kind of can the ophthalmosyringe of regulating liquid temp.
Background technology
Current intravitreal drug conveyer device delivers to vitreous body medicine, to avoid causing the complication such as retina shedding by the orbiculus ciliaris of retinal tissue that do not have of eyes.In prior art, a kind of ophthalmosyringe improving drug conveying can mentioned with reference to No. 101495072nd, Chinese invention patent disclosed in 29 days July in 2009, comprise with the nose cone of heating clamber, heating component and pin, described nose cone and described heating clamber is heated by described heating component, with be used in treatment eyes dosage form from solid state transformation for liquid state, and described nose cone gives described pin enough heat trnasfer, again solidifies in described pin to prevent described dosage form from described liquid state.But this syringe but can not carry out micro-control to the temperature of heating clamber, or thermostatic control, and directly cannot observe out the temperature of medicinal liquid, this can produce puzzlement to the medication judgement of doctor, and fluid temperature may be damaged or stimulation target tissue improperly.
Utility model content
In order to overcome above-mentioned shortcoming, this utility model object is that providing a kind of can show and the ophthalmosyringe of regulating liquid temp.
This utility model is realized by following technical measures, a kind of ophthalmosyringe, comprise: the pin there is the nose cone of heating clamber, be located at the fluid chamber of described heating chamber, being connected with described fluid chamber one end, the plunger assembly in order to alter room space size be connected with the described fluid chamber other end and the heating component be positioned on described nose cone, wherein, described nose cone is provided with display and temperature adjustment buttons, and described heating component comprises temperature feedback mechanisms.
Further, described heating component after by described temperature adjustment buttons design temperature, keeps heated at constant temperature.
Further, described heating component not pin described in direct heating.
Further, described pin is self-packing.
Further, described temperature feedback mechanisms, according to the change of the temperature in described fluid chamber, changes heated condition in real time, to keep fluid temperature constant.
Further, described heating component is also integrated with temperature control device, and described temperature feedback mechanisms, temperature control device and described Temperature displaying mechanism are all integrated in described nose cone part, can unload with described nose cone part.
Further, described nose cone part is demountable structure.
This utility model is according to the temperature-controlling module that also can show real time temperature by arranging scalable in the nose cone of parcel fluid chamber, make the fluid temperature in fluid chamber can easily according to doctor need setting, and doctor can control fluid temperature by the display screen subsidiary according to nose cone portion in real time, be convenient to doctor's medication, and reduce the generation probability of complication.

Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of ophthalmosyringe of this utility model is described further.
As shown in Fig. 1 to Fig. 3, a kind of ophthalmosyringe 100 of this utility model, comprising: the nose cone 11 with heating clamber, the fluid chamber 21 being located at described heating chamber, the pin 22 be connected with described fluid chamber 21 one end, the plunger assembly 23 in order to alter room 21 space size be connected with described fluid chamber 21 other end and the heating component be positioned on described nose cone 11.Medicine in fluid chamber 21 can be heated by heating component.
Described heating component comprises temperature control unit 13 and drives heating unit, and in the present embodiment, this driving heating unit is heater coil 12.Described temperature controlled unit comprises drive circuit (not shown), the temperature adjustment buttons 15 as input control structure, the display 14 as output display structure and detects feedback circuit (not shown).
Please consult further shown in Fig. 3, its concrete temperature adjusting principle as shown in the figure, after user design temperature, by control circuit, drive heater coil 12 pairs of oven heats, the temperature of medicine in simultaneous temperature sensor monitoring fluid chamber 21, and feed back to control circuit by amplifying circuit, to determine the need of continuation heating, and through amplifying the electric signal of adjustment, change into Temperature displaying on display 14 through A/D signal.Be convenient to the temperature that doctor grasps medicinal liquid in real time like this.After this temperature control unit heats a period of time, constantly adjusted the temperature of heating clamber according to the change of the temperature in described fluid chamber by temperature feedback mechanisms, the temperature of medicinal liquid can stablize remain on setting person setting temperature on, make doctor can control the temperature of medicinal liquid accurately, avoid occurring because of fluid temperature improperly damaging or the problem of stimulation target tissue.
In addition, described display 14 and temperature adjustment buttons 15 etc., temperature input and output and governor motion are all integrated in nose cone 11, so only nose cone 11 need be unloaded i.e. replaceable fluid chamber 21 or other infusion sets, are convenient to apparatus and safeguard and apparatus sanitized.The entry needle 22 that described ophthalmosyringe 100 adopts adopts self sealing structure, and part is located in nose cone portion, described heating component is pin 22 described in direct heating not, but heat described pin 22 by the mode of the heat radiation of heating clamber, reduce to avoid medicinal liquid temperature when the described pin 22.
In sum, these are only preferred embodiment of the present utility model, scope of the present utility model should do not limited with this, namely every simple equivalence change done according to this utility model claims and utility model description with modify, all should still belong in scope that this utility model patent contains.
