Why Calimate May Cause Constipation?

This article presents a case involving a patient who was taking calcium polystyrene sulfonate (generic name, hereafter referred to as Ca-type ion exchange resin), marketed in Japan under the brand name Kalimate, for the treatment of hyperkalemia. The patient was in a nearly bedridden condition, and after starting oral administration of the drug, developed extremely hard stools and severe difficulty with defecation. Constipation has been reported as a side effect of this medication, but in this case the symptoms were particularly severe. (This is an individual example, and the severity of symptoms varies among patients.) Using this case as a starting point, I would like to review the mechanism of action of the drug and organize the possible factors that may influence stool consistency.

Understanding Edema and the Role of Compression: Insights from Nursing Practice and Patents

Have you ever experienced swelling in your legs after a long day of work? Edema, commonly known as swelling, is not only uncomfortable in daily life but also an important issue in nursing and elder care settings. Recently, I joined a training session that covered lymphatic drainage techniques and compression bandaging. It gave me an opportunity to revisit the mechanisms behind edema and the innovations being developed to address it. In this article, I will walk you through what edema is and why it happens, how blood and lymphatic circulation are involved, and what impact edema can have on health and daily life. I will then explain the mechanisms by which compression helps improve edema and finally introduce a Japanese patent that proposes an innovative design for compression stockings.

Semisolid Enteral Nutrition②: How Intragastric Gelation Works

In my previous article, “Semisolid Enteral Nutrition,” I explained formulations that are already semisolid before administration. This time, I’ll take a closer look at formulations that are delivered in liquid form but may turn into a gel once they reach the stomach. On August 10, 2025, the Silver Industry Newspaper reported that Morinaga Milk Industry launched a new intragastric gelling product called “Wanoka.” Although this type of product has existed before, the release of a new one suggests that there still seems to be steady demand for enteral nutrition products. In this article, I’ll explain the possible mechanism of intragastric gelation, referencing related patent documents. Disclaimer: This article may contain affiliate links (PR).

Solving Injection Resistance with the Plunger Assist Ring

e Design Innovations for Less Painful Injections” and “Pressure in Nursing Care: How It Affects Injections, IV Drips, and Pressure Ulcers” However, injection comfort is not determined by devices alone. Proper technique is essential to make the most of these tools. In practice, difficulty in pushing the syringe plunger can become a real burden for clinicians, and this often increases patient discomfort and pain. This article introduces the Plunger Assist Ring, a device designed to address this challenge. Based on patent information, we’ll explore its features, the structure of a syringe, and the physical factors that make plungers harder to push.

Adhesive Tapes for Wound Closure: “FASNAHT” and “Steri-Strip”

When someone gets a deep cut, many people may immediately think, "This will need stitches." Yet in clinical practice, there is often another option: using adhesive wound closure tapes instead of sutures. This article introduces medical wound closure tapes, which are still not commonly known outside healthcare settings, focusing on two products: FASNAHT by Nichiban and Steri-Strip by 3M.—focusing on two products: FASNAHT by Nichiban and Steri-Strip by 3M. Their structure and features are explained based on related patent documents.
