Description

A kind of auxiliary wearing tool

Technical field

The utility model relates to a kind of auxiliary wearing tools of blood glucose meter transmitter, belong to technical field of medical equipment.

Background technique

Now occurs a kind of dynamic blood sugar monitoring system in the market.Dynamic blood sugar monitoring system (RGMS) is that investment is faced in recent years One kind that bed uses is novel to continue dynamic blood sugar monitoring system, it connects a detecting head similar to syringe needle, and detecting head is for being placed in Subcutaneous tissue.Detecting head diameter very little, patient is without obvious pain and sense of discomfort when merging.Instrument standoff certain time is from detecting head The electric signal for receiving primary reflection change of blood sugar, by multi collect to electric signal average value transform into blood glucose value and store Come.It can recorde several hundred a blood glucose values daily.Dynamic Blood Glucose Monitoring instrument can also store the times such as dining, movement, medication simultaneously. This can allow patient not have to the pain for enduring needle bundle again daily, and it can provide daily blood glucose figure, blood glucose figure fluctuation in more days The brief summary of trend analysis and daily blood glucose level data is the new breakthrough of blood sugar test.

It is highly important for how steadily, accurately by detecting head merging subcutaneous tissue.

Utility model content

The utility model will solve the above problems, to provide a kind of transmitter of blood glucose meter.The utility model has hair Steady feature is penetrated, so as to solve the above problems.

The specific technical solution that the utility model solves the above problems is as follows:

A kind of auxiliary wearing tool, including shell and setting propel component shell is intracorporal, and the component of propelling includes dress Load portion propels portion, control unit and propels limiting section；

Loading part, for loading transmitter；

Portion is propelled, the other end is fixedly connected with the loading part including one end and is fixed on institute for the guide rod of free end, one end The main spring stating loading part and being set on the guide rod, by the reset response of the main spring by the loading part bullet Out；The guide rod top is provided with guide groove, and lower part is provided with locating notch；

Control unit is threaded through on the guide rod for controlling the pop-up of the loading part, including inner casing, installation part, radial direction Spring and pressing piece；There is the through-hole passed through for the guide rod and with leading with what the guide groove matched in the middle part of the inner casing Block；The installation part is fixedly connected with the inner casing, for inner casing to be fixed in the shell；Described radial spring one end is supported It leans against the inner casing other end to be resisted against on the pressing piece, provides elastic reset effect for the pressing piece；The pressing piece Middle part has the through-hole passed through for the guide rod, and has the locating piece cooperated with the locating notch；The main spring The other end is also fixedly connected with the pressing piece；

Limiting section is propelled, for preventing excessively propelling for loading part, the free end end of the guide rod is set, and has There is the structure in the aperture for the through-hole worn for the guide rod being greater than on the pressing piece, so that guide rod is in main spring elasticity Displacement under reset response is limited.

As a preferred embodiment of the above technical solution, described to propel limiting section, it is the pipe close and pipe close of position limiting convex ring including end Fixed column；The free end of the guide rod is hollow structure, and the pipe close is used to fill in the free end of the guide rod；The guide rod It is upper that there is the through-hole radially filled in convenient for the fixed column.

It as a preferred embodiment of the above technical solution, further include closed-loop, the closed-loop is mounted on the emission port of the shell, The end of the limiting section is connect with the end-enclosed of the shell.

As a preferred embodiment of the above technical solution, further include loading limiting section, be one for preventing the excessive of loading part from pushing away dress The annular sleeve that the emission port of the shell is set and is located at around the loading part, and limit knot is formed with the loading part Structure；The position limiting structure includes the limited block being arranged on the loading part outer profile and is arranged on the loading limiting section simultaneously Protrusion is stretched in limited block cooperation.

As a preferred embodiment of the above technical solution, the pressing piece further includes button, is additionally provided with described in confession on the shell The through-hole that button stretches out.
