Embodiment Construction

[0036] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0037] see Figure 1-Figure 4 , the present invention provides a technical solution: a toughness testing device for a platelet storage bag, including a base 5, and a pressure mechanism arranged above the base 5 for applying a squeezing force to the storage bag, and for calculating the pressure value of the storage bag The pressure testing mechanism and the quantitative injection mechanism 8 for quantitatively injecting test fluid into the storage bag solve the problem that the previous platelet storage bags lack effective toughness testing devices.

[0038] The specific working principle: first press the lifting button 61, the power shaft 2 of the electric telescopic rod 4 will raise the pressing block 9 to the top; then take the platelet storage ...

Abstract

The invention provides a device and method for testing toughness of a platelet storage bag. The device comprises a pedestal, a pressure mechanism which is disposed above the pedestal and is used for applying an extrusion force to the storage bag, a pressure testing mechanism which is used for calculating a pressure value applied to the storage bag, and a quantitative injection mechanism which is used for quantitatively injecting a test fluid into the storage bag. The platelet storage bag toughness testing device solves a problem that an existing platelet storage bag lacks an effective toughness testing device, is reasonable in structure, utilizes the pressing block in unit area to carry out extrusion testing on the storage bag injected with different fluid amounts, can accurately obtain the optimal stress state and the most appropriate injection flow of the storage bag, and the quality of the storage bag can be tested.

Description

technical field [0001] The invention relates to a toughness testing device and a testing method of a platelet storage bag, and relates to the technical field of platelet storage bag production and processing equipment. Background technique [0002] Platelet storage bags are mostly used for the storage of platelets in blood, and are mostly made of sterile and non-toxic modified polyolefin materials, and are sealed and formed by hot pressing. In the prior art, after the platelet storage bag is produced, it is impossible to conduct a reasonable and effective toughness test. The so-called toughness test includes testing the tear resistance and maximum extrusion force performance of the platelet storage bag to ensure that the platelet storage bag The normal use of the platelet storage bag can reduce the damage rate, which is beneficial to the later improvement; among them, the best way is to test the anti-extrusion ability of the platelet storage bag, which can best reflect the q...
