[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Figures 1-4 The dispensing device shown includes a sleeve 1, which is detachably mounted on the inlet pipe of a container 5 via a snap fastener, wherein the sleeve 1 connects a medicine bottle containing medicine to the container 5; a penetrating needle 2, which is placed inside the sleeve 1, wherein the penetrating needle 2 penetrates the seal of the medicine bottle and introduces the liquid medicine in the bottle into the container 5 for mixing through a hole; and an assembly assembly 3, which is disposed between the penetrating needle 2 and the sleeve 1, wherein the assembly assembly 3 is used to remove the penetrating needle 2 from the sleeve 1 for replacement of the penetrating needle 2 separately. First, the sleeve 1 is snapped onto the inlet pipe of the container 5, and then the medicine bottle containing medicine is inserted into the sleeve 1, so that the penetrating needle 2 breaks the seal of the medicine bottle and inserts into the medicine bottle to introduce the liquid medicine in the bottle into the container 5 for mixing.

[0033] Figure 2 and Figure 3The assembly component 3 shown includes: a cylinder 31, which is fixedly connected to the penetrating needle 2, wherein the cylinder 31 encloses the penetrating needle 2, and is placed inside the sleeve 1 to separate the liquid medicine from the sleeve 1; and an intercepting rod 32, which is rotatably mounted on the penetrating needle 2 via a retaining ring, wherein the size and shape of the surface of the intercepting rod 32 are adapted to the size and shape of the inner wall of the through hole 37 opened on the inner wall of the sleeve 1. By setting the assembly component 3, the cylinder 31 is first manually moved, causing the cylinder 31 to move the penetrating needle 2, which in turn moves the intercepting rod 32. When the cylinder 31 moves to the position where it is fully inserted into the sleeve 1, the penetrating needle 2 and the intercepting rod 32 pass through the inside of the through hole 37. At this time, the intercepting rod 32 is manually rotated. This causes the intercepting rod 32 to rotate around the through needle 2. When the intercepting rod 32 moves to a cross shape with the through hole 37, it intercepts and limits the through needle 2, thus achieving the assembly and fixation of the through needle 2 and the sleeve 1. When the medicine bottle is inserted into the sleeve 1, it enters the cylinder 31, allowing the cylinder 31 to work with the through needle 2 to guide the medicine into the container 5. At the same time, the cylinder 31 separates the medicine in the medicine bottle from the inner wall of the sleeve 1, preventing the sleeve 1 from contacting the medicine. This means that only the through needle 2 needs to be replaced separately in the future, reducing the possibility of medicine residue remaining on the sleeve 1 and the through needle 2, which would otherwise require replacing the entire sleeve 1 and the through needle 2 and waste materials. This improves the practicality of the feeding mechanism.

[0034] Figure 2 and Figure 3 The assembly assembly 3 shown also includes: an auxiliary plate 33, which is fixed to the interceptor rod 32. The surface of the auxiliary plate 33 is rectangular and has multiple protrusions. By setting the auxiliary plate 33, personnel can manually rotate the auxiliary plate 33 to drive the interceptor rod 32 to rotate, improving the convenience and stability of manually rotating the auxiliary plate 33. The assembly assembly 3 also includes: a rubber pad 34, which is fixed to the side of the interceptor rod 32 near the sleeve 1. The surface of the rubber pad 34 has multiple protrusions. By setting the rubber pad 34, the gap between the interceptor rod 32 and the sleeve 1 can be filled, reducing the occurrence of autonomous rotation and shaking of the interceptor rod 32.

[0035] Figure 2 and Figure 3The assembly assembly 3 shown also includes: a cotton plate 36, which is fixed to the cylinder 31. The cotton plate 36 is sleeved on the surface of the cylinder 31 to absorb accidentally splashed medicine. By setting the cotton plate 36, the accidentally splashed medicine can be absorbed, reducing the situation where the medicine adheres to the inner wall of the sleeve 1. The assembly assembly 3 also includes: a positioning post 35, which is fixed to the side of the cylinder 31 near the interceptor bar 32. The positioning post 35 is inserted into the positioning hole 38 opened in the inner wall of the sleeve 1 to quickly position the cylinder 31. By setting the positioning post 35, the positioning post 35 can be inserted into the positioning hole 38 to limit the cylinder 31, reducing the situation where the cylinder 31 rotates when the personnel rotate the interceptor bar 32.

[0036] Figure 4 The device also includes a reinforcement component 4, which includes an airbag 42. The airbag 42 is fixedly installed at the inlet position of the sleeve 1 via a ring 41. The airbags 42 are evenly distributed on the inner side of the ring 41 to support the medicine bottle inserted into the sleeve 1. By setting the reinforcement component 4, when the medicine bottle is inserted into the sleeve 1, the medicine bottle is placed inside the ring 41, so that the multiple airbags 42 inside the ring 41 are in contact with the surface of the medicine bottle and support and reinforce it, thereby achieving auxiliary stability of the medicine bottle, reducing the large-scale shaking and tilting of the medicine bottle after it is inserted into the sleeve 1, and improving the stability of the medicine bottle when delivering medicine.

[0037] Figure 4 The reinforcing component 4 shown also includes a rubber protrusion 43, wherein the rubber protrusion 43 is uniformly fixed to the contact surface between the airbag 42 and the medicine bottle. By setting the rubber protrusion 43, the friction between the airbag 42 and the surface of the medicine bottle can be increased, reducing the possibility of slippage between the medicine bottle and the airbag 42.

[0038] Working principle: First, the sleeve 1 is attached to the feed pipe of the container 5 by means of a buckle. Then, the medicine bottle containing the medicine is inserted into the sleeve 1, so that the penetrating needle 2 breaks the seal of the medicine bottle and is inserted into the medicine bottle to introduce the medicine liquid into the container 5 for mixing.

[0039] First, manually move the cylinder 31, causing the cylinder 31 to move the penetrating needle 2, which in turn moves the intercepting rod 32. When the cylinder 31 is fully inserted into the sleeve 1, the penetrating needle 2 and the intercepting rod 32 pass through the through hole 37. At this point, manually rotate the intercepting rod 32, causing it to rotate around the penetrating needle 2. When the intercepting rod 32 moves to a cross-shaped arrangement with the through hole 37, it intercepts and limits the penetrating needle 2, thus achieving the assembly and fixation of the penetrating needle 2 and the sleeve 1. When the medicine bottle is inserted into the sleeve 1, it enters the cylinder 31, allowing the cylinder 31 to work with the penetrating needle 2 to guide the medicine into the container 5. At the same time, the cylinder 31 separates the medicine in the medicine bottle from the inner wall of the sleeve 1, preventing the sleeve 1 from contacting the medicine. Therefore, only the penetrating needle 2 needs to be replaced separately in the future.

[0040] When the medicine bottle is inserted into the sleeve 1, it is placed inside the ring 41, so that the multiple air bladders 42 inside the ring 41 are in contact with the surface of the medicine bottle and support and reinforce it, thereby achieving auxiliary stabilization of the medicine bottle.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
