In this way, the insulin glucagon injection device 100 can stop inputting insulin and can input glucagon to raise blood sugar, so as to avoid occurrence of such situations and ensure safety in use.
Referring to fig. 1-5, in one embodiment, an insulin glucagon injection device 100 includes a mounting housing 110, a regulation assembly 120, and a plurality of reservoir assemblies 130. The mounting housing 110 has a mounting cavity 111 and a liquid outlet 112 communicating with the mounting cavity 111. The adjusting assembly 120 is disposed in the mounting cavity 111 and is capable of opening or closing the liquid outlet 112. The plurality of liquid storage assemblies 130 are disposed on the mounting housing 110, and ends of the liquid storage assemblies 130 extend into the mounting cavity 111 and are connected with the adjusting assembly 120. The adjustment assembly 120 can select the liquid storage assemblies 130 when moved, so that one of the liquid storage assemblies 130 is communicated with the liquid outlet 112.
The mounting housing 110 is a housing structure of the insulin glucagon injection device 100, the mounting housing 110 is a hollow structure, a hollow part inside the mounting housing is a mounting cavity 111, and part of components of the insulin glucagon injection device 100 are located in the mounting cavity 111. The mounting housing 110 further has a liquid outlet 112, the liquid outlet 112 is communicated with the mounting cavity 111, the liquid outlet 112 is an output end of the insulin glucagon injection device 100, and the insulin glucagon injection device 100 realizes output of liquid through the liquid outlet 112. It will be appreciated that the shape of the mounting housing 110 is not limited in principle and may have a square, circular, oval, polygonal or other irregular cross-sectional shape, provided that the mounting of the components of the insulin glucagon injection device 100 is accomplished.
The adjusting assembly 120 is disposed in the mounting cavity 111, and the adjusting assembly 120 is disposed between the liquid outlet 112 and the liquid storage assembly 130, and the liquid storage assembly 130 is used for storing liquid. Alternatively, the number of reservoir assemblies 130 is two; of course, in other embodiments of the invention, the number of reservoir assemblies 130 may also be three, four or even more. A member of the adjustment assembly 120, such as a sealing plug 1221 (mentioned later), is movable in the mounting cavity 111 to open or close the liquid outlet 112. For simplicity of description, the movement of the direct adjustment member 120 in the mounting cavity 111 replaces the movement of some part of the adjustment member 120 in the mounting cavity 111, as to the movement of some part of the adjustment member 120 in the mounting cavity 111, is mentioned later.
The adjustment member 120 is movable between a plurality of reservoir assemblies 130 to select a reservoir assembly 130 to communicate with the adjustment member 120. The adjustment assembly 120 is capable of reciprocating movement within the mounting cavity 111 and is maintained in a desired position. The adjusting component 120 can be selectively connected with one of the liquid storage components 130, and at this time, the liquid in the liquid storage component 130 can be output through the liquid outlet 112 by the adjusting component 120. Moreover, the adjustment assembly 120 can be movable within the mounting cavity 111, and the adjustment assembly 120 can select a desired reservoir assembly 130.
For example, at some point in time, the adjustment assembly 120 is required to communicate with one of the fluid reservoir assemblies 130 to output fluid from that fluid reservoir assembly 130. When other conditions need to change the output liquid, the adjusting component 120 is controlled to move in the mounting cavity 111, and the position of the adjusting component 120 is adjusted, so that the adjusting component 120 and the previous liquid storage component 130 are turned off and the next liquid storage component 130 is communicated, thereby realizing the output of the liquid in the liquid storage component 130 and achieving the purpose of switching the liquid of the insulin glucagon injection device 100.
Optionally, a reservoir assembly 130 is located in the mounting housing 110. That is, the liquid storage assembly 130 is located inside the installation housing 110, and the installation housing 110 wraps the liquid storage assembly 130, so that safety in use can be ensured, the liquid storage assembly 130 is prevented from being separated from the installation housing 110, and the liquid storage assembly 130 can be reliably fixed in the installation housing 110.
Of course, the reservoir assembly 130 may also be partially located within the mounting housing 110. That is, one end of the liquid storage assembly 130 is located in the mounting housing 110, and the other end of the liquid storage assembly 130 is exposed out of the mounting housing 110. In actual use, the liquid storage assembly 130 can be directly operated on the outer side to realize the transportation of the liquid in the liquid storage assembly 130.
