Collaborative Arrangement Disclosure [Text Block]	Collaborative and Other Arrangements On February 3, 2017, we entered into two Manufacturing and Supply Agreements ("MSAs") whereby (i) Pfizer will manufacture and supply us with certain agreed upon products for an initial five-year term with a one-time two-year option to extend and (ii) we will manufacture and supply Pfizer certain agreed upon products for a term of five or ten years depending on the product, also with a one-time two-year option to extend. The MSAs provide each party with mutually beneficial interests and both of the MSAs are to be jointly managed by both Pfizer and ICU. The initial supply price, which is subject to an annual update, is in full consideration for all costs associated with the manufacture, documentation, packaging and certification of the products. On January 1, 2021, we amended our MSA with Pfizer, whereby we manufacture and supply certain agreed upon products to Pfizer. The amendments included a change to the term of the agreement to end on December 31, 2024 with Pfizer's unilateral election to extend through December 31, 2025. Other changes to the terms of the MSA included (i) amendments to our level of supply of products to Pfizer, (ii) certain changes to our manufacturing lines, (iii) updates to our supply price with added volume price tiers for annual periods and (iv) certain minimum purchase requirements for certain products. On February 1, 2022, effective as of January 1, 2022, upon our request, Pfizer executed a Product Addendum (the "Product Addendum") to our MSA, whereby Pfizer manufactures and supplies to us certain agreed upon products. The Product Addendum includes the supply of additional product to us subject to certain time and pricing terms and conditions. The Product Addendum includes a minimum purchase obligation of $29.6 million and expires on November 30, 2022. As of March 31, 2022, we had satisfied the minimum purchase obligations under the Product Addendum.
