Description

The invention relates to a medical protective glove, in particular surgical gloves.

In general, non-sterile protective gloves, by means of which contact with infectious material or hazardous substances is prevented, as well as sterile protective gloves are known.

To avoid surgical site infection (SSI), sterile surgical (OP) protective gloves are used. All resources must be optimized to reduce the SSI rate (Kramer A et al. GMS Hyg Infect Control. 2016). Sterile surgical gloves play a central role here; they protect the patient and operating room staff from the transmission of pathogens and body fluids (Lindeque B. et al. Infection after primary total hip arthroplasty. Orthopedics. 2014). The valid one 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 so far not had a major impact.

Wearing sterile double gloves is a widespread method, as a large number of studies have shown that it significantly reduces the risk of injury and infection (Guo YP et al. Is double-gloving really protective? Am J Surg. 2012). The decisive factor here is the injury to the inner glove. Most of the studies that investigate the effect of so-called double gloving show that the inner glove is only perforated in a small percentage (up to 82% intact). The protection against blood contact increases by wearing double gloves by 5 to 10 times; through the use of so-called indicator gloves, which indicate perforations due to discoloration of the glove, even up to 13 times, as it is for example in the scriptures DE 3925938 C1 is revealed. In addition, there is the knowledge that when double gloves are used, the outer glove also has fewer perforations than the sole outer glove when only one surgical glove is worn. With regard to wearing comfort and subjective tactile perception, however, double gloving is rated rather negatively in many studies, so that many surgeons refuse to wear double gloves or to use indicator gloves.

Furthermore, patents exist in the prior art for gloves with different wall thicknesses.

The Book of Revelation CN 105931689 B discloses a manufacturing process for medical gloves with different wall thicknesses for use in the field of radiation protection and in orthopedics. The surgical gloves disclosed herein have thin wall thicknesses, especially in the area of the fingers, to improve tactility.

The Book of Revelation CN 107361439 A also describes a method for producing a medical glove which has different wall thicknesses. This is achieved in that, following the conventional manufacturing process for the disposable glove, the glove is integrally immersed in rubber latex, so that the finger part of the glove is thickened.

The prior art discloses either thinner or thicker wall thicknesses for sterile surgical gloves. Thinner wall thicknesses lead to an improved tactile sensitivity, but have a higher risk of damage due to the material thickness. In contrast, gloves with a larger wall thickness offer better protection against mechanical stress, but have a significantly reduced tactile sensation.

Furthermore, through the publication of the font DE 10 2007 021 014 A1 Protective gloves are known which are multi-layered, whereby a thicker wall thickness is achieved in the area of the fingers than in the areas of the palm and back of the hand, as well as the cuffs, which are not multi-layered. The thicker wall thickness in the finger area increases the protective capacity of the glove in the area of the fingers and improves the elasticity of the single-layer cuffs.

By means of the publication of the font DE 10 2015 113 861 A1 Protective gloves are disclosed which reveal areas that are designed with knobs or grooves. The knobs or grooves make it easier to remove the glove from the hand.

Furthermore, the material used in the prior art for medical gloves, in particular surgical gloves, natural latex rubber or acrylonitrile-butadiene rubber. These materials show weaknesses in particular when subjected to mechanical stress, which leads to micro and macro cracks in the gloves. Furthermore, these materials have antigens and can therefore trigger allergies in both patients and users.

To prevent allergies, gloves made of neoprene are known, for example in DE 696 30 300 T2 disclosed.

Presentation of the invention

It is therefore the object of the invention to eliminate the disadvantages of the prior art and to provide a protective glove, in particular a sterile surgical protective glove, which offers increased protection against damage, in particular due to mechanical loads, and thereby enables increased tactile sensitivity.

It is the object of the invention to provide a protective glove which offers increased protection against damage, in particular due to mechanical loads occurring at certain points, and thereby enables an increased tactile sensation.

It is also an object of the invention to provide a particularly tear-resistant and anti-allergic protective glove.

This problem is solved by the features listed in the claims.

According to various embodiments, a protective glove according to the invention has a wall thickness S. Finger spaces for the fingers of a hand, as well as a palm space connected to each of the finger spaces and a cuff area adjoining the palm space. The protective glove, or at least its surface, is divided into stress zones which, depending on their degree of stress, have different wall thicknesses from one another. The stress zones include in particular unloaded zones, main stress zones and high stress zones. The different load zones have different wall thicknesses from one another S. where the unloaded zone is the wall thickness S1 , the main load zone is the wall thickness S2 and the high load zone the wall thickness S3 having. It also applies that 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 the unloaded zone thinnest and the wall thickness S3 the main load zone is thickest. Furthermore, the wall thicknesses S2 the main stress zones and / or the wall thickness S3 of the high-stress zones 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 on. These recesses ensure that the urgently needed tactile sensation is maintained despite the increased amplification of the respective stress zone. The ones with the small wall thickness of S1 or S2 formed recesses are protected from damage by the higher wall thicknesses surrounding the recesses.

According to various embodiments, the wall thickness is S2 formed by the wall thickness S1 a material is cast on or put on.

According to various embodiments, the wall thickness is S2 formed by the wall thickness S1 a material is cast in the shape of a flap or placed on it.

According to various embodiments, the wall thickness is S3 formed by the wall thickness S2 or the wall thickness S1 a material is cast on or put on.

According to various embodiments, the wall thickness is S3 formed by the wall thickness S2 or the wall thickness S1 a material is cast in the shape of a flap or placed on it.

According to various embodiments, the molded or attached material is molded or placed on the inside of the protective glove. However, it is also conceivable that the material that has been cast on or placed on is cast on or placed on the outside of the protective glove.

The recesses are particularly preferably arranged on the inside of the protective glove. This prevents liquids, dirt, etc., which act on the glove from outside, from being deposited in the recesses. However, an arrangement of the recesses on the outside of the glove is also conceivable.

Furthermore, an extension of the at least three load zones to further load zones, for example 4 or 5 load zones, is conceivable, the load zones having the previously mentioned wall thicknesses S1-S3 of the respective stress zones are different.

The protective glove according to the invention extremely advantageously has a tear-resistant and / or hypoallergenic material, the tear-resistant and / or hypoallergenic material comprising polyurethane polymer.

Another advantageous 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 as a result the mechanical stress centers are particularly reinforced in order to reduce the intraoperative damage and ensure the tightness of the glove. The important tactile sensation remains intact, the risk of damage is reduced.

With the proposed protective glove, damage caused by the singular wall thickness gradient in the mechanical stress zones is reduced. By incorporating recesses, for example circular recesses, the tactile sensation remains partially unaffected. This ensures greater patient safety and better self-protection for the OR staff.

The stress zones can be determined on the basis of research or evaluation results of already damaged protective gloves. For example, the stress zones in endoprosthesis operations are different from those in minimally invasive arthroscopy operations or in intestinal operations. According to the main stress zones analyzed, the wall thickness is reinforced and can thus guarantee better protection against micro (≤ 1mm) and macro damage (> 1mm).

The use of 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.
