Problems solved by technology

[0004] Compared with the traditional technology mentioned above, this method has the same place in that the dose control is performed at the back end. In the actual operation process, there are many difficult influencing factors in this back-end control method, such as external Vibration, shaking of the human body itself or difficulty in controlling the rotation angle, thermal expansion and contraction caused by ambient temperature affecting the accuracy of the screw, etc., may lead to uncontrollable front-end output doses
Therefore, the output dose of similar products currently on the market can only be calculated in units of hours, and the cumulative output dose cannot be accurately calculated for a single injection.
[0005] At the same time, this design can only inject a dose of more than 0.05ul at a time even under the current most precise screw, making it difficult to achieve a smaller level of dose delivery

Embodiment 1

[0054]Such asfigure 1 As shown, the present embodiment provides a medium infusion structure including a storage chamber 1, a dose infusion assembly 2, and a power device 11. The storage cavity 1 is connected to the dose output device 2, providing a certain pressure through the power device 11, and the medium is input to the dose infusion assembly 2. The storage cavity 1 is connected to a medium source 4 for supplementing the medium within the storage cavity 1.

[0055]In the present embodiment, the dose infusion assembly 2 includes a first multi-pass valve 21, a second multi-pass valve 22, and a cavity 23, and a reciprocating device 24 is connected in the cavity 23, and a side of the reciprocating device 24 is connected. The first cavity space is independent of the second cavity space on the other side, and the first cavity space is changed to the movement or deformation of the volume of the second cavity. The first multi-pass valve 21 and the second multi-pass valve 22 each include a ...

Embodiment 2

[0068]Such asFigure 4As shown, on the basis of Example 1, the number of storage cavities 1 is two, and the number of dose infusion assembly 2 is also two. The first multi-pass valve 21 of all dose infusion assembly 2 and the third port of the second multi-pass valve 22 are connected together and take out an output port 3. The cavity 23 volume of the two dose infusion assembly 2 may be the same or different, and the second cylinder space of the two storage cavities 1 is connected to each other, so that the pressure of the respective output positions of the outer wall of the second cylinder space can be equal.

[0069]Of course, in other embodiments, it may be that a storage chamber 1 corresponds to a plurality of dose infusion assembly 2, or a plurality of storage cavity 1 may correspond to one dose infusion assembly 2. For micropa media infusion, the use of such a multi-cylinder block can effectively avoid the length of the storage chamber 1, which is too long, the second reciprocating...

Abstract

The invention provides a medium infusion structure, a medium infusion method, a micro-dosage secretion pump, and an insulin pump, comprising: a power device, a storage cavity, and a dose infusion assembly; the output ends of the storage cavity are respectively connected to the The valves at both ends of the dosage infusion assembly; the power provided by the power device squeezes out the quantitative medium of the existing volume of the dosage infusion assembly. The present invention can accurately deliver the effect of a single dose, and the single delivered dose will not be changed due to the influence of external factors.

Description

Technical field[0001]The present invention relates to the field of medium infusion, and in particular, to a medium infusion structure, a medium infusion method, a micro-dose secretion pump, an insulin pump.Background technique[0002]The conventional medium infusion is to transmit the medium from the rear end of the line from the line to the front end output by applying a pressure to the front end of the pressurizing device such as the pipeline. The amount of the conveying medium can be calculated by the sensor set on the pipeline. . In the field of small doses and even micropatar, since the amount of medium is very small, it is difficult to control by the rear end pressurized and controlled delivery.[0003]Taking insulin injection as an example, Patent Document CN101137408 discloses a portable mechanical insulin injection device, referring to the manner of manual rotating components instead of the motor in insulin pumps in the insulin pump in the insulin pump in the insulin pump in ac...
