Problems solved by technology

[0002] At present, the inner packaging bag of the perfusion device sold on the market is an ordinary polymer material packaging bag that has not been inflated by positive pressure. This inner packaging bag does not have the function of showing the sealing of the perfusion device in the bag; The inspection of the sealing of the perfusion device is not for the finished product before leaving the factory, so there is a hidden danger of leakage in the finished product; the manufacturer of the perfusion device warns medical workers on the inner packaging bag of the perfusion device: "It is strictly forbidden to use the perfusion device in the bag if the packaging is damaged." , indicating that the perfusion device in the inner packaging bag does have a hidden danger of leakage

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0025] Such as figure 1 As shown, the seal detection device of the hemoperfusion device of the present invention includes an inner packaging bag 3 and a humidity card 2; the inner packaging bag 3 is placed with the hemoperfusion device 1, and the inner packaging bag 3 is filled with positive pressure gas , the humidity card 2 is embedded in the surface of the inner packaging bag 3 or placed in the inner packaging bag 3 for detecting the humidity in the inner packaging bag 3 . The humidity card 2 is a cobalt-free relative humidity card; the cobalt-free relative humidity card is a multi-point humidity card, and the display value coverage of the multi-point humidity card is: 60% to 100%, at least 70% to 90% ;The display value interval is 10%, and the relative humidity is ac...

Abstract

The invention provides a seal detection device of a blood perfusion device. The seal detection device of a blood perfusion device includes an inner packaging bag and a humidity card, wherein a blood perfusion device is arranged in the inner packaging bag, and the inner packaging bag is filled with positive pressure gas; the humidity card is embedded into the surface of the inner packaging bag or arranged in the inner packaging bag for detecting the humidity in the inner packaging bag.; the positive pressure inflation pressure in the inner package bag is 116 kPa to 130 kPa; and the inner package bag is subjected to an internal pressure of 132 kPa or more. The seal detection device of a blood perfusion device can conveniently determine the sealing property of the blood perfusion device, andcan conveniently and accurately determine whether the internal packaging bag is perfect and has no leakage.

Description

technical field [0001] The invention relates to the field of seal detection of a hemoperfusion device, in particular to a seal detection device for a hemoperfusion device. Background technique [0002] At present, the inner packaging bag of the perfusion device sold on the market is an ordinary polymer material packaging bag that has not been inflated by positive pressure. This inner packaging bag does not have the function of showing the sealing of the perfusion device in the bag; The inspection of the sealing of the perfusion device is not for the finished product before leaving the factory, so there is a hidden danger of leakage in the finished product; the manufacturer of the perfusion device warns medical workers on the inner packaging bag of the perfusion device: "It is strictly forbidden to use the perfusion device in the bag if the packaging is damaged." , indicating that the perfusion device in the inner packaging bag does have a hidden danger of leakage. Before me...
