Does the silicone reservoir have the ability to resist negative pressure or extrusion?

During medical operations, silicone reservoir are important liquid collection and temporary storage devices. Their performance stability is directly related to the operation effect of the entire suction system and the safety of clinical operations. In this type of medical consumables, negative pressure resistance and extrusion resistance are evaluation indicators that cannot be ignored. Especially in vacuum suction, body fluid collection, surgical perfusion and other links, liquid storage tanks are often in a repeatedly changing pressure environment. If the structure is unstable or the material strength is insufficient, it is easy to collapse, retract or even rupture, thus affecting normal use.
As a polymer elastic material commonly used in the medical field, silicone has high flexibility and good resilience. When under pressure, it can effectively buffer external forces and maintain the integrity of the tank structure. This material also has natural shape memory properties, which can quickly restore its original shape after the external force is removed, reducing the possibility of long-term deformation. In addition, medical-grade silicone usually undergoes multiple vulcanization treatments and structural optimization during the production process, so that it can still maintain strong resistance to physical damage under extreme conditions such as high temperature, high pressure or low pressure.
In a vacuum environment, the liquid storage tank may be subjected to strong negative pressure from the inside. If the tank material is soft, the wall thickness is insufficient, or the structural design is unreasonable, it is easy to collapse, resulting in reduced suction efficiency and even blockage or backflow risks. silicone reservoir with good anti-negative pressure performance can continuously withstand pressure fluctuations in the vacuum state without deformation, ensuring that the suction system is always in a smooth and stable state.
From the perspective of structural design, high-quality silicone reservoir usually adopt reinforcing ribs or spiral grooves to make the tank body have high pressure resistance while maintaining flexibility. This type of design does not affect the compressibility of the tank body, and can effectively prevent the occurrence of concave deformation when subjected to external mechanical forces. In addition, the interface part of the tank body will also be thickened, reinforced or encrypted to improve the overall force balance and avoid damage caused by local stress concentration.
During operation and storage and transportation, medical liquid storage tanks may encounter external force interference such as accidental squeezing and handling impact. The buffering performance of silicone material also shows its unique advantages in such situations. Even if subjected to short-term external pressure, the liquid storage tank can still quickly restore its shape and continue to maintain its original capacity and sealing performance, and will not affect the safety of use due to structural changes.
It is worth mentioning that some silicone reservoir also use special mold technology to accurately control the ratio of wall thickness and tank height to optimize its internal support structure, so that it can maintain elasticity while obtaining good anti-collapse ability. This not only improves the pressure resistance level of the tank, but also provides stronger safety protection for actual use.
