  • SSI surgical site infection
  • OP sterile surgical
  • All resources must be optimized to reduce the SSI rate
  • Sterile surgical gloves play a central role here; they protect the patient and operating theater staff from the transmission of pathogens and body fluids (Lindeque B. et al. Infection after primary total hip arthroplasty. Orthopedics. 2014).
  • the current ISO DIN EN 455 for surgical gloves makes only minimal mechanical demands on natural latex (polyisoprene), latex and latex-free surgical gloves.
  • DIN EN 455-1 describes a leak test with 1000ml (water retention test 2-3 minutes), DIN EN 455-Z includes standardized dimensions and tear resistance of the entire glove of 9N.
  • DIN EN 455-3 and-4 relate to biocompatibility and aging / durability. There is no information on a minimum material thickness. Mechanical loads occurring intraoperatively are not taken into account. Therefore, the consideration of mechanical stress in the further development of surgical gloves has not yet had a major impact.
  • the surgical gloves disclosed herein have thin wall thicknesses, especially in the area of the fingers, to improve tactility.
  • the subject matter of document GB 2 493 288 A relates to medical gloves and in this regard is concerned with helping users avoid needle stick and / or sharp injuries and infections.
  • This invention provides different gradient wall thicknesses within the same glove. There are areas of single and double wall thickness within the same glove. The areas that require tactile sensation are single-walled, while the most injury-prone areas are double-walled. Areas that require a tactile sensation, but are less prone to injury, are flat, single-walled and consist of a thin layer of synthetic membrane.
  • the publication WO 2017/031 522 A1 discloses gloves which comprise a polymer coating, optionally including a fabric insert, and a reinforcement which is arranged on part of the polymer coating or on part of the fabric insert. Maintaining a tactile sensation is not taken into account.
  • Document US 5644797 A discloses a glove which, by introducing a solid material, prevents the glove from being pierced with a needle or a similarly pointed object. It is also disclosed how the glove enables objects to be held in an improved manner. Maintaining a tactile sensation despite increased protection is not disclosed.
  • US Pat. No. 5,794,266 A discloses a glove made of thin latex or rubber material which is suitable for medical or other delicate interventions and at the same time offers comfort by creating air pockets in the glove.
  • the inner layer of the glove has protrusions so that the contact area between the glove and the hand is reduced.
  • the projections should allow a comfortable ventilation of the hand.
  • Each fingertip of the glove is devoid of convex protrusions to increase sensitivity.
  • US Pat. No. 5,317,759 A discloses a surgical barrier glove for protecting surgeons and health care workers.
  • the glove includes an inner layer, an outer layer overlying the inner layer, and a plurality of closely spaced pillars at the interface between the layers that are integrated into one layer and extend towards the other layer.
  • the pillars provide protection against needle sticks that extend completely through the glove, while allowing the flexibility of the glove and the transmission of tactile senses through the thickness of the glove.
  • the pillars resist puncture of the glove by suture needles.
  • the pillars are integrated into the inner layer.
  • the tactile sensation should be achieved by the columns, which have a columnar cross-section and are separated from one another by narrow slits. This enables a relative vertical movement of adjacent columns, which is intended to indirectly transfer the tactile feeling through the thickness of the glove to the hand of the wearer, so that the Wearer retains the ability to feel or sense surgery through the thickened and puncture-proof parts of the glove.
  • Gloves especially surgical gloves, natural latex rubber or acrylonitrile butadiene rubber are used.
  • these materials show weaknesses when subjected to mechanical stress, which can lead to micro and macro cracks in the gloves.
  • these materials have antigens and can therefore trigger allergies in both patients and users.

  • the wall thickness S1 is smaller than the wall thickness S2 and the wall thickness S2 is smaller than the wall thickness S3, so that the wall thickness S1 of the unloaded zone is the thinnest and the wall thickness S3 of the main load zone is the thickest.
  • the wall thickness S2 of the main stress zones and / or the wall thickness S3 of the high stress zones are designed in such a way that they enable tactile sensation by means of cutouts which are arranged within the respective zone.
  • the recesses have a wall thickness of S1 or S2. These recesses ensure that the urgently needed tactile sensation is maintained despite the increased amplification of the respective stress zone.
  • the recesses formed with the small wall thickness of S1 or S2 are protected from damage by the higher wall thicknesses surrounding the recesses.

  • An advantageous further embodiment is a smooth transition from one wall thickness to the next wall thickness.
  • the advantage of the protective glove according to the invention is that the wall of the protective glove has singular wall thickness gradients, and thereby particularly the mechanical stress centers are reinforced in order to reduce the intraoperative damage and to ensure the tightness of the glove. The important tactile sensation remains intact, the risk of damage is reduced.
  • Evaluation results of already damaged protective gloves can be determined.

  • the wall thickness is reinforced and can thus guarantee better protection against micro ( ⁇ 1mm) and macro damage (> 1mm).
  • polyurethane polymers significantly improves the mechanical load-bearing capacity of the glove. Due to the material properties, it can be used by allergy sufferers. This results in significantly improved patient safety and better self-protection for the OR staff.
