When the liquid is taken, the adapter part 3 is arranged at the first position, the liquid medicine in the medicine bottle body 8 can enter the inner cavity of the liquid taking tube 4 along a passage formed by the liquid taking channel 104 and the inlet 401 of the liquid taking tube 4, when the liquid is taken to reach the preset amount, the adapter part 3 can be arranged at the second position, the liquid taking channel 104 is disconnected with the inlet 401 of the liquid taking tube 4, and the liquid in the liquid taking tube 4 can flow to the outside from the outlet 403 for use. The liquid in the liquid taking pipe 4 flows to the outside through extrusion power.
From the above description, it can be seen that the liquid taking device provided by the present invention does not need to open the cover 1 when taking liquid, and can achieve quantitative liquid taking by setting the range of the liquid taking tube 4, so as to greatly reduce the possibility of the external environment contacting with the liquid in the medicine bottle body 8, reduce the occurrence of the situation that the liquid medicine inside the medicine bottle body 8 is polluted, and be beneficial to ensuring the efficacy of the medicine. The liquid taking device provided by the invention is provided with the air return channel, and the air return can be carried out on the solution cavity of the medicine bottle body 8 in the liquid taking process or after the liquid taking is finished.
Of course, the air return channel is only limited in function, and may be the same channel as the liquid extraction channel 104, or may be different channels, as long as air return is achieved.
Referring to fig. 1, in one embodiment, the inlet 401 and the outlet 403 of the liquid extraction tube 4 are disposed at opposite ends of the tube, and the tube is mounted to the adapter 3. The adapter part 3 is mounted on the cover 1 in a rotationally sealed manner at one end, i.e. the adapter part 3 can rotate relative to the cover 1 and is in sealing contact with the cover.
The adapter component 3 is at least provided with a first channel and a second channel, when the adapter component 3 rotates to a first position relative to the cover body 1, the liquid taking pipe 4 is communicated with the liquid taking channel 104 through the first channel, and the second channel is not communicated with the liquid taking channel 104; when the adapter component 3 rotates to the second position, the first channel is disconnected from the liquid taking channel 104, and the second channel is communicated with the liquid taking channel 104 to form an air return channel.
After the liquid taking device and the medicine bottle body 8 are assembled to form the medicine bottle assembly in the embodiment, in order to reduce packaging, the liquid taking tube 4 and the medicine bottle body 8 are located on the same side in an optimal normal state, when liquid is taken, the adapter part 3 is rotated to the first position, the medicine bottle body 8 can be squeezed or the medicine bottle body 8 is inverted to enable liquid medicine in the medicine bottle body 8 to enter the inner cavity of the liquid taking tube 4 along the liquid taking channel 104 and the first channel, after liquid taking is finished, the adapter part 3 is rotated to the second position to close the communication channel between the liquid taking channel 104 and the inlet 401 of the liquid taking tube 4, the second channel and the liquid taking channel 104 are communicated at the same time to enable the two to form an air return channel, namely, external air can enter the medicine bottle body 8 along the second channel and the liquid taking channel 104 at the moment, so that the internal air pressure of the medicine bottle body 8 is balanced.
In this embodiment, the switching part 3 realizes the conversion of first position and second position through rotating to realize getting the conversion of liquid and return-air, simple and convenient.
The adapter component 3 can be directly connected to the cover body 1, and can also be indirectly connected to the cover body 1 in a rotating manner, i.e., the cover body 1 can also be provided with the connecting block 2, and the adapter component 3 is rotatably arranged on the connecting block 2.
Specifically, the connecting block 2 is disposed on the cover body 1, fig. 1 shows that the connecting block 2 is transversely disposed on the cover body 1, the connecting block 2 includes an installation shaft section which is disposed outside the cover body 1 in a leaking manner, and the adapter member 3 is rotatably installed on the installation shaft section.
