DAHLHAUSEN

DAHLHAUSEN is a German medical technology company based in Cologne that supplies hospitals with instruments, disposables and clinical accessories. Its trading company is P. J. Dahlhausen & Co. GmbH [10]. The business traces its roots to 1854, when the surgical instrument maker Johann Wilhelm Grevenberg began making scalpels and bandages to his customers' individual specifications [2]. It has carried the Dahlhausen name since 1915 and is now run by the fourth generation of the family.

Unlike most companies in the beauty and personal-care world, DAHLHAUSEN does not sell to consumers. It states that it sells only to commercial customers [1], such as hospitals, specialist dealers and international partners. Its range, which the company puts at more than 3,000 products, covers anaesthesia, surgery and patient care. It also includes a small set of everyday ward supplies, among them disposable razors, hair combs, toothbrushes and body-care items for patients. The company is active, and in 2024 it moved into a new headquarters in Cologne.

The company tells its early history as part of a wider change in medicine. According to its history page, the founding of the Grevenberg business coincided with a new era in which chloroform anaesthesia made modern surgery possible. Johann Wilhelm Grevenberg, a surgical instrument maker, saw that doctors needed new specialised tools. The company says he was among the first to make scalpels and bandages to order, shaped to what each customer asked for.

The second founding figure is Peter Josef Dahlhausen, who took over the business in 1915. Under him the firm began serial production of surgical instruments, which the company describes as a genuine novelty at the time. Its own account of that period paints a picture of a very different hospital. Plastic played no part yet. Doctors worked with metal hammers, syringes made of metal and glass, metal needles and small bottles for filling ether.

The name changed with the new owner. The history page states that the Grevenberg company has been "Dahlhausen" since 1915. The headquarters has remained in Cologne throughout, and the company still describes itself as having a "Cologne heart".

The company's two main pages give different dates for when the Dahlhausen family took charge. The history page dates the takeover by Peter Josef Dahlhausen to 1915 [2]. The company page, by contrast, states that DAHLHAUSEN has been in family hands "since 1921" [3]. The company does not explain the gap. The two dates may describe separate steps, such as a takeover and a later transfer of ownership, but neither page says so. The founding year of 1854 is the same on every page.

The next turning point came in 1964. Peter Josef Dahlhausen junior added single-use products to the range, which the company says made it the first business in Germany to do so [2]. In its own words, this laid the foundation for modern hygiene standards in hospitals. Disposable articles are now a routine part of clinical work, and the move shaped much of what the company sells today.

Over the following decades, DAHLHAUSEN brought a long list of products to market. The company names disposable scalpels, dispensers, suction tubing for operating theatres and artificial humidifiers for breathing air among them. Its range grew from classic instruments to hernia meshes made in Aachen and high-tech urethral stents from Israel. The company describes this mix as a full range built on its own manufacturing and on strong partners.

In the 2000s the Cologne family firm grew into an international company. It opened its own subsidiaries abroad and built a growing sales network, carrying its products beyond Germany. The company page describes a business with companies in twelve countries, worldwide export activity and a global purchasing network.

In 2024 DAHLHAUSEN moved into a new headquarters at Adam-Riese-Straße 4 in Cologne. The building holds a DGNB Gold certificate, a German rating for sustainable construction. With the move, the company says it stopped using gas for heating altogether [5]. In October 2025 it published its first voluntary sustainability report, covering the 2024 reporting year.

At some point the company also took over a long-standing product line from another firm. According to its homepage, the company Prämeta transferred its medical technology business to DAHLHAUSEN after 70 years [1]. Since then DAHLHAUSEN has offered the full range of Prämeta venous tourniquets. The homepage does not give a date for the transfer.

DAHLHAUSEN describes itself as a family business in its fourth generation. Ulrich Dahlhausen leads the company as managing director, and he shares the management with Inga Simsheuser [7]. The company stresses personal responsibility, short decision paths and a long-term outlook as the values of the family at the top.

The Cologne company sits within a larger structure, the Dahlhausen Group. The group calls itself a family-owned European healthcare group with roots dating back to 1854. It reports more than 800 employees, nine production sites and companies in twelve countries [4]. Those countries are mainly in Europe, but the group also lists companies in Israel, South Africa and Taiwan [6]. P. J. Dahlhausen & Co. GmbH itself had 163 employees in 2024, according to its sustainability page.

The group explains its set-up as a holding company with a network of specialist businesses beneath it. The holding provides framework, stability and direction, while the individual companies stay close to their own markets and customers. Each company keeps its own expertise and responsibility.

The group says it grows through targeted acquisitions and projects that fit its portfolio and values. It sums up its approach to ownership in one line: family ownership means thinking in generations, not in quarters. Its group page adds a slogan that sets out the same idea, describing the business as "a group of people", not a corporation.

DAHLHAUSEN's tagline is "Medizin braucht Fortschritt. Seit Generationen." In English, this means "Medicine needs progress. For generations." The company presents its long history as evidence of an attitude: medicine changes, and the company changes with it.

Its stated mission is practical. The company says its goal is to support medical teams reliably, so they can concentrate on safe use and on caring for their patients. It describes its focus as quality, innovation and reliability. According to DAHLHAUSEN, its products come out of close collaboration with doctors, nursing staff and patients. The company presents itself as more than a supplier, calling itself a problem-solver, partner and pioneer.

At group level, the Dahlhausen Group sets out four guiding principles. The first is dependability before complexity. The group links this to control over production and supply chains, and says it is strengthening its own production in Europe across its nine sites. The second is innovation with a purpose. Here the group says it develops products only where they create real value in clinical practice, listening to users and simplifying where it can. The third is growth with discipline, through acquisitions that add professional value. The fourth is independence within a strong group, which describes the freedom of each company inside the network.

The group frames its role against the pressures facing healthcare. It notes that hospital care is becoming more complex and that cost pressure is growing. In that setting, it says, stability and trust matter most, alongside dependable supply, practical solutions and long-term partnership. The group states that it is "not interested in growth at any cost" but in lasting value. Its declared ambition is to be the European healthcare partner that people can rely on.

The company page describes DAHLHAUSEN as one of the leading full-range suppliers of clinical accessories in Europe. It addresses three main audiences: hospitals, specialist dealers and export partners. For each it promises a dedicated team. The company also runs a logistics and production centre in Halberstadt, Germany, where it carries out a range of tasks for customers.

DAHLHAUSEN's range is organised by clinical area. Its catalogue covers anaesthesia and intensive care, surgery, dermatology, gynaecology and urology, heart and lung care, emergency management, ward supplies, sterilisation and cleaning, and ultrasound and diagnostics. Typical items include suction catheters, breathing bags and masks, laryngoscopes, wound drainages, scalpel blades, urinary catheters and thoracic drainage sets.

The dermatology section is small and centres on diagnostics, with biopsy punches used to take skin samples. The closest overlap with personal care lies in the ward-supply section. There, under hygiene and nursing aids, the company lists body-care products, examination gloves, disposable razors, hair combs, toothbrushes and hot-and-cold compresses for patients in hospital.

Several products are featured prominently on the company's pages. The MIRUS system manages anaesthetic gas, with versions such as the MIRUS Controller Isoflurane. The fasciotens system uses fascial traction in abdominal wall surgery, which the company presents as the solution for that field. Other featured lines include the SECCO PROTECT closed faecal drainage system, Glutack for atraumatic mesh fixation, the Hegenberger retractor, the SonoEye ultrasound line and the Prämeta venous tourniquets.

Not every product in the range is made by DAHLHAUSEN itself. The company combines its own manufacturing with partner products, and acts as a distributor for some of them. One example is Niviu, a system that measures and records a patient's urine output automatically. It is a medical device made by Elixion Medical GmbH in Düsseldorf, and DAHLHAUSEN handles its sale in Germany [9]. The system replaces manual, error-prone hourly measurement at the bedside. It sends the values directly to the hospital's patient data system. The product page says it can save around one hour of nursing time per bed per day. Further uses, such as monitoring post-operative drainage and neonatal intensive care, are described there as development goals of the manufacturer, not as part of the system's current intended purpose.

On quality, the company says it works to ISO 13485, the international standard for quality management of medical devices, and in line with the EU Medical Device Regulation. These are standards for medical products, not for cosmetics.

Some DAHLHAUSEN products have been the subject of regulatory safety notices. The International Medical Devices Database run by the International Consortium of Investigative Journalists lists two field safety notices for P. J. Dahlhausen & Co. GmbH devices [10]. One concerns a trocar catheter for pleural drainage, and the other concerns ECG electrodes of type 440. A field safety notice is a routine corrective-action notice sent to the users of a device. The database states that its listings do not suggest or imply any improper conduct, and it gives no dates for the two notices.

DAHLHAUSEN has published detailed information about its environmental work, most of it tied to the new Cologne headquarters. With that building, the company says, it cut annual gas use of about 470,000 kilowatt-hours to zero in 2024 [5]. Heat now comes entirely from electric heat pumps, and a rooftop solar installation helps produce the power. According to the company page, its warehouse in Cologne runs on solar power from its own roof. The building's DGNB Gold rating is the main external certificate for the project.

The company completed an energy audit to the DIN EN 16247-1 standard in 2024. It also runs a whistleblower system in line with German laws on whistleblower protection and supply-chain due diligence. On the product side, it points to Sharpsafe Gen.5 sharps containers made from recycled material and to silicone tubing free of harmful substances.

Its first sustainability report follows the voluntary VSME standard of EFRAG, a European framework for reporting on environmental, social and governance matters. The report covers the 2024 reporting year and is dated "Cologne, October 2025". In it, the company set out plans for 2025 and 2026, including more solar capacity, further electrification of its vehicle fleet and more recyclable outer packaging.

DAHLHAUSEN is an active company. It runs a live online shop for its commercial customers and publishes ongoing product news on its website. Its latest dated public activity is the sustainability report issued in October 2025, which followed the move into the new Cologne headquarters in 2024. The company remains in the hands of the Dahlhausen family, with Ulrich Dahlhausen leading it in the fourth generation. Through the wider Dahlhausen Group, it operates in twelve countries.
