In the embodiment, four first accommodating grooves 132 are arranged on the first platform 131; the second accommodating grooves 421 of the second dialing part and the clamping jaws 531 of the clamping jaw assembly 53 are also corresponding to four; in actual operation, according to the content of the prescription, confirm the number of medicine bottles (one to four bottles) required for the current infusion bag, through the cooperation of the feeding conveying line and the second dialing part 42, the medicine bottles enter the corresponding second accommodating grooves 421 in turn.

[0044] In the pre-dissolution mechanism for intravenous drug flushing and preparation of the embodiment, the front end of the conveying line is taken as an example, that is, Figure 2 The orientation of the front view is shown; the preferred orientation distribution of the components of the embodiment is described: the left side of the front end of the conveying line (the left side of the front view) is provided with a clamping mechanism; the upper side of the front side of the conveying line and the clamping mechanism is provided with a pre-dissolution clamp shaking mechanism, and the injection module of the pre-injection mechanism is arranged at the upper right side of the pre-dissolution clamp shaking mechanism; the transfer mechanism is arranged at the left side of the clamping mechanism, wherein the fourth horizontal moving module of the clamping mechanism is arranged below the mounting frame and provides left-right direction movement for the second dialing part; the fifth horizontal moving module is arranged at the left side below the fourth horizontal moving module and provides front-back direction movement for the third dialing part; the shaking assembly and the guide assembly of the pre-dissolution clamp shaking mechanism provide left-right direction shaking for the moving frame; the second horizontal moving module of the pre-dissolution clamp shaking mechanism provides left-right direction movement for the pre-dissolution clamp; a plurality of first accommodating grooves are arranged at intervals in the left-right direction; a plurality of second accommodating grooves are arranged at intervals in the left-right direction; a plurality of clamping jaws are arranged at intervals in the left-right direction; the first horizontal moving module provides left-right direction movement for the first dialing part; the third lifting module provides up-down direction movement for the clamping jaw assembly from the clamping mechanism to the upper side; the third horizontal moving module provides front-back direction movement for the clamping jaw assembly from the upper side of the clamping mechanism to the upper side of the pre-dissolution clamp shaking mechanism.

[0045] The pre-dissolving mechanism for intravenous infusion of the embodiment is used for conveying the medicine bottles distributed at intervals forward and backward on the feeding conveying line. The second shifting part of the clamping mechanism is located at the rightmost side, so that the second accommodating groove at the leftmost side of the second shifting part corresponds to the medicine bottle on the conveying line. When the medicine bottle enters the second accommodating groove at the leftmost side, the fourth horizontal moving module drives the second shifting part to move leftward by one position of the second accommodating groove, and continuously receives the medicine bottle. At the same time, the first medicine bottle is shifted to the medicine receiving platform by the second shifting part. Until the four second accommodating grooves all receive the medicine bottles, the fourth horizontal moving module also drives the second shifting part to move to the leftmost position. Then, the third shifting part is driven by the fifth horizontal moving module to move forward and cooperate with the second shifting part, so that the medicine bottle is pushed to the second V-shaped sidewall at the front side of the second accommodating groove, and the medicine bottle is positioned in the clamping assembly. After that, the clamping jaw driving element of the transfer mechanism drives the clamping jaw to open, and the clamping jaw assembly moves through the third lifting module and the third horizontal moving module to correspond to the bottle neck of the medicine bottle on the clamping assembly. The clamping jaw driving element of the transfer mechanism drives the clamping jaw to hold the medicine bottle. The clamping jaw assembly holding the medicine bottle is driven by the third lifting module and the third horizontal moving module to move above the first accommodating groove of the pre-dissolving clamp of the pre-dissolving clamp shaking mechanism (at this time, the pre-dissolving clamp is located at the left side of the pre-dissolving clamp shaking mechanism by the driving of the second horizontal moving module). Then, the clamping jaw assembly releases the medicine bottle, and the medicine bottle is correspondingly put into the first accommodating groove. The first shifting part is driven by the first horizontal moving module to push the medicine bottle against the right sidewall of the first accommodating groove, so that the medicine bottle is positioned in the pre-dissolving clamp. Then, the second horizontal moving module drives the pre-dissolving clamp to move rightward until the rightmost medicine bottle on the pre-dissolving clamp corresponds to the injection needle of the pre-injection mechanism. The moving end of the first lifting module of the injection module and the second lifting module move downward with the needle shifting limiting plate until the needle shifting limiting plate is located at the top side of the medicine bottle. At the same time, the second lifting module inserts the injection needle into the medicine bottle, and a small amount of solvent is injected into the medicine bottle from the common solvent by the power of the peristaltic pump. Then, the second lifting module drives the injection needle to move upward and shift out of the medicine bottle. At this time, the medicine bottle will not be moved downward with the needle shifting limiting plate. Then, the moving end of the first lifting module rises upward, and the subsequent solvent injection of the medicine bottle is repeated. Then, the second horizontal moving module drives the pre-dissolving clamp to return to the initial position at the leftmost side. The shaking assembly is started to shake the medicine bottle left and right quickly, so that the medicine in the medicine bottle is quickly dissolved in the solvent. After a certain period of time, the medicine bottle of the pre-dissolving clamp is taken out by the subsequent equipment, and the steps of conveying, clamping, transferring, pre-injection, and pre-dissolving shaking are repeated.

[0046] The above embodiments should not limit the present application in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion fall within the protection scope of the present application.
