Technical Field

[0001] The technical fields involved include: mechanical design and manufacturing design, fluid mechanics. Background Art

[0002] The overall appearance of the dressing changer refers to Figure 1 and Figure 2 in the attached drawings of the specification, and the specific illustration is as shown in Figure 3 、 4 in the attached drawings of the specification, Figure 3 、 4 where A11 is an infusion catheter, and A11 is connected to a medicine bottle (bag) through a medical puncture connector. In Figure 3 、 4 of the attached drawings of the specification, Figure 15 where A5 is a sealed air filter. When the seal plug is opened, the liquid flows out. In Figure 3 、 4 of the attached drawings of the specification, Figure 7 where A2 is a liquid shunt tube, Figure 3 、 4 in the attached drawings of the specification, Figure 12 where A4 is a liquid storage device, Figure 3 、 4 where A9 is a medical flow stop clamp. When A5 is opened, air enters A2, and A9 is in a closed state. The liquid flows into A2 until the chamber is filled. Then, close the left A5 and keep the right A5 open, forming a sealed space except for the right first chamber. Then open all A9s. The liquid in the first chamber flows out to A4 through A11 between A2 and A4, and the remaining chambers are sealed spaces and the liquid cannot flow out. In Figure 3 、 4 of the attached drawings of the specification, Figure 10 where A3 is a rubber piston, Figure 7 where A2-04 is a rear air outlet. When the liquid in the chamber is exhausted, the left piston is pushed by the liquid in the next chamber and moves to the right until it blocks the upper and lower liquid flow pipes. Then open A2-04, and the first chamber is sealed and no liquid flows out. The air in the next chamber enters, allowing the liquid to flow out normally. And so on, each ventilation pipe is designed with a bend to prevent the liquid from flowing out. In Figure 7 where A2-01 is an air outlet hose, with a separate pipe on the left and a combined pipe on the right, which also reduces the operation steps. In Figure 7 where A2-02 is an expansion pipe, A2-03 is the main chamber, and A2-04 is the rear air outlet, Figure 7 、 9 where A2-05 is a piston snap ring. A2-03, A2-05, and A2-02 are made of pp or pc materials, and the rest are medical plastics. In Figure 3 、 4Among them, A5 is a sealable air filter, A6 is an air filter, A7 is a sealing joint, and A13 is a support tube. In the accompanying drawings of the specification Figure 3 , 4 Among them, A1 is a support housing, A10 is a support belt. A1 protects the main circulation system and fixes the positions of A2 - 04. Cooperating with A10, this device can be suspended. In the accompanying drawings of the specification Figure 3 , 4 Among them, A8 is an infusion set connector, which is connected to the puncture joint of the infusion set and finally flows into the infusion set. Summary of the Invention
