Embodiment 1
[0050] When dispensing medicines, dispensing personnel (such as nurses, etc.) need to prepare thousands of medicines every day, and each medicine needs to be replaced with a new medicine dissolving device. Therefore, the medicine dissolving device and the handle need to be able to be quickly inserted and removed, and sealed.
[0051] When the drug dissolver is dispensing, it needs to be driven pneumatically through the subsequent handle. The pneumatic pressure is relatively high when driving. Generally, there is a gap between the joint end of the drug dissolver and the handle (there is no seal between them), and the high pressure during driving It will cause the gas in the drug dissolver to rush out from the gap at a high speed, which may cause damage or cannot be driven out (drug dissolver).
[0052] Such as figure 1 As shown, a drug dissolver has a jacket 1, the jacket is provided with a cone 2, the jacket has a cavity, the cone is arranged on the jacket, and communicates wi...
Embodiment 2
[0060] As the drug dissolver described in embodiment 1, the difference of this embodiment is that, as Figure 2A As shown, the shape of the protrusion 3 of the drug dissolver is the same as the cross section of the outer cover, so that the inner wall of the protrusion 3 fits and is the same as the inner wall of the outer cover, so as to prevent the inner wall of the outer cover from being uneven due to the protrusion 3. The movement of the rubber plug inserted therein is hindered.
[0061] The cross section of the overcoat of the drug dissolver and the protrusion 3 can be circular, also can be elliptical, and can also be other shapes such as star, zigzag (can be selected or designed according to actual needs during specific implementation) ), as long as the cross-section of the coat is identical to the shape of the protrusion 3.
[0062]Preferably, the outer cross section of the drug dissolver and the protrusion 3 are circular, so that the production is convenient and the dru...
Embodiment 3
[0066] In order to complete aseptic dispensing, it is not only necessary to maintain the sterile environment in the cavity of the drug dissolving device during the dispensing process, but also to replace the bacteria in the drug dissolving device when replacing the drug dissolving device. In the present invention, a filter is arranged at the front end of the handle to blow out uniform, dispersed, and non-intersecting air source / clean air flow in the same direction to replace the air at the front end of the handle, so as to achieve a local cleanliness of class 100, so as to ensure the replacement environment of sterility. At the same time, for the bacteria at the back end of the rubber stopper of the drug dissolver, the bacteria in it are replaced by blowing with uniform, dispersed, and non-intersecting air source / clean air. However, in the current drug dissolving device, there are many bacteria hidden, and it is difficult to blow out (replace) the bacteria by simply blowing wi...
