Abstract

The utility model relates to an insulin pen capable of refrigeration. The insulin pen consists of a propeller, a pen cap, a suspension loop, a semiconductor refrigeration device, a temperature sensor and a USB plug, wherein the pen cap and a refill are arranged at the lower end of the propeller; the suspension loop, the temperature sensor and the USB plug are arranged at the lower end of the pen cap, and the semiconductor refrigeration device is arranged at the inner part of the pen cap. The insulin pen provided by the utility model not only can be used for injecting insulin, but also can be used for connecting with a USB for refrigeration. The insulin pen has the advantages of simple structure, and convenience in use, and is suitable for broad diabetics.

Description

The novopen that can freeze

Technical field

This utility model relates to a kind of novopen, especially a kind of novopen freezing.

Background technology

Novopen is a kind of insulin injection device, and size is more bigger than pen, and insulin is placed in pen in the mode of pen core, can carry, and the used time only need be pulled up the cap for brush, just can carry out injection of insulin, and operation is very easy.The insulin that it uses is special writing-core type insulin, and concentration is different from general insulin, is U-100, i.e. 100 units per ml (general insulin concentration is U-40,40 units per ml, Mei Zhi 400 units).Pen core insulin be generally 300 units/or 150 units/, change pen core after being finished and continue to use again.

Existing novopen is mainly made up of the cap for brush, pen core frame, frame for movement, in the time that people use, first the cap for brush is extracted, again pen core frame is outwarded winding, after again pen core is installed in pen core frame, be loaded on syringe needle, again pen core frame is connected with machinery, then put the pen cap, in the time using, only need take off the pen cap and just can use, existing novopen all has the effect of insulation, but the time of insulation is not long, the time that has arrived especially hot insulation in summer is just shorter, and this has brought much inconvenience.

Utility model content

In order to overcome the deficiency of above-mentioned existing novopen, the purpose of this utility model is to provide a kind of novopen freezing, and it adopts and is provided with semiconductor cooling device at the inwall of the cap for brush.

In order to realize the technical scheme that the purpose of this utility model adopts be: a kind of novopen freezing, is characterized in that: it is made up of propeller, the cap for brush, hangers, semiconductor cooling device, temperature inductor, USB plug; Described propeller is cylindric, and lower end is provided with the cap for brush and pen core; The described cap for brush is cylindric, and lower end is provided with hangers, temperature inductor and USB plug, and inside is provided with semiconductor cooling device; Described semiconductor cooling device is arranged on the inwall of the cap for brush, and radiating surface contacts with the inwall of the cap for brush, and heat-absorbent surface is towards pen core frame; Described hangers upper end is provided with female thread, is connected with the lower end of the cap for brush by screw thread.

The beneficial effects of the utility model are: it can either be used for insulin injection, can connect again USB interface refrigeration, and diabetics simple in structure, easy to use, widely applicable.

Detailed description of the invention

In the first embodiment shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of novopen freezing, is characterized in that: it is made up of propeller, the cap for brush, hangers, semiconductor cooling device, temperature inductor, USB plug; Described propeller is cylindric, and lower end is provided with the cap for brush and pen core; The described cap for brush is cylindric, and lower end is provided with hangers, temperature inductor and USB plug, and inside is provided with semiconductor cooling device.

In the second embodiment shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, described angle of rake upper end is provided with injection push button, and lower end is provided with piston masthead, piston rod part and boss; The upper end of described pen core frame is connected with angle of rake lower end by screw thread, for filling the pen core with insulin; The described cap for brush is that a kind of Heat Conduction Material is made, and the inwall of upper end is provided with groove, and lower end is provided with external screw thread; Described hangers upper end is provided with female thread, is connected with the lower end of the cap for brush by screw thread, the cap for brush is hung up with convenient for the protection of USB plug.

In the 3rd embodiment shown in Fig. 4, Fig. 5, described semiconductor cooling device is arranged on the inwall of the cap for brush, and radiating surface contacts with the inwall of the cap for brush, and heat-absorbent surface is towards pen core frame, for absorbing the heat in pen core frame, and dissipation of heat outside the cap for brush; Described USB plug is arranged on the lower surface of the cap for brush, provides electric energy for connecting computer USB interface to semiconductor cooling device and temperature inductor; Described R1 is semiconductor cooling device, and IC is temperature inductor, and the temperature in temperature inductor IC detects pen core frame, higher than when setting value, is sent the signal of telecommunication, and the signal of telecommunication amplifies for No. VT through audion, will drive semiconductor cooling device R1 to work.

Use when this utility model, first the cap for brush extracted and pen core frame is outwarded winding, after will install in pen core frame with the pen core of insulin again, load onto syringe needle, again pen core frame is connected with propeller, then puts the pen cap, screw on hangers, in the time that needs freeze, only hangers need be outwarded winding, USB plug is inserted in USB jack, just can freeze, simple in structure, easy to use.
