Superior Haemostatic Performance

Delivering rapid haemostasis within minutes while offering high absorbency and broad surface-area density to control bleeding efficiently. It is fully absorbed by the body within 21 days, ensuring biocompatibility and leaving no residue. Designed for ease of use, it can be positioned and repositioned without sticking to instruments or retaining a memory effect. The range includes four specialised formats: H-T for routine capillary and minor venous or arteriolar bleeding, H-D for managing heavier blood loss, F for covering large or irregular surfaces and reaching difficult areas, and S for laparoscopic procedures, where easy trocar insertion and expansion on contact with air provide excellent handling and absorbency.

  • Rapid, effective bleeding control: Provides haemostasis within minutes, with high absorbency and broad surface coverage.
  • Fully absorbable and versatile: Absorbed by the body within 21 days and available in four specialised formats for different surgical and bleeding needs.

The Cost Saving Opportunity of Okcel®

A Case Study

A Major Cardiac NHS Foundation Trust adopted Okcel® after being made aware of the huge savings that could be achieved by switching from the most commonly used oxidised cellulose haemostat to the Okcel® alternative. The Cardiac Hospital and International Centre of Excellence have a large requirement for the cotton wool form of Okcel®, Okcel® F, due to the nature of Cardiac Surgery. Okcel® F offers faster haemostasis, more accurate placement and increased adaptability over the original form of the product. Over a 4-year period, the Major Cardiac Trust has saved over £350,000 from the previous provider and continues to save over £90,000 a year.

Okcel® H-T Original Oxidised Cellulose Haemostats

Okcel® H-T is a textile material made from long, natural staple cotton. This knitted version of the absorbable haemostatic material is of standard density. It is used to control capillary bleeding, as well as bleeding from smaller veins and arterioles during surgery and minimally invasive procedures.

  • Made from long, natural staple cotton with a knitted, standard-density structure.
  • Designed to control capillary bleeding and bleeding from smaller veins and arterioles.

Okcel® H-D Heavy-Duty Oxidised Cellulose Haemostats

Okcel® H-D is a knitted textile version of the absorbable haemostatic material that is thicker, denser and more effective. It is suitable for stopping and controlling the diffusion of higher volumes of blood and bleeding from veins and arterioles during surgical procedures when it is not possible to use ligation or other conventional methods to stop bleeding.

  • Thicker, denser knitted structure provides enhanced haemostatic effectiveness.
  • Designed for higher-volume bleeding, including bleeding from veins and arterioles when ligation or conventional haemostatic methods are unsuitable.

Okcel® F Fibrous Oxidised Cellulose Haemostats

Okcel® F is a non-woven, multi-layered fibrous version of the absorbable haemostatic material that is more lightweight and extremely flexible. It is used to achieve haemostasis over large areas, for surface applications and in hard to reach places.

  • Lightweight and highly flexible non-woven, multi-layered absorbable haemostatic material.
  • Ideal for haemostasis over large surface areas and hard-to-reach locations.

Okcel® S Strengthened Fibrous Oxidised Cellulose Haemostats

Okcel® S is a strengthened, non-woven cotton wool form of oxidised cellulose, offering superior handling, higher absorbency and is designed for use in laparoscopic surgery. The properties of Okcel® S mean it does not stick to instruments, it’s easy to pass through the laparoscopic portal and has no memory effect. The two smaller sizes of Okcel® S are also vacuum sealed, condensing the size of the product, allowing for easier passage in laparoscopic surgery. The product then naturally increases in size when exposed to air. Okcel S has the indication to control capillary, venous and arteriolar bleeding.

  • Designed for laparoscopic surgery – easy to pass through laparoscopic portals, does not stick to instruments and has no memory effect; smaller sizes are vacuum sealed for easier insertion.
  • Effective bleeding control – highly absorbent oxidised cellulose designed to control capillary, venous and arteriolar bleeding.

Fasster Haemostasis

Okcel can generate haemostasis within minutes, faster than other oxidised cellulose products on the market.

Easier to Position

Okcel® can be used in open and minimally invasive surgery and is easier to position than traditional haemostats.

More Absorbent

Okcel is more absorbent that traditional haemostats due to the higher surface area of the product.
