Description

The utility model relates to clothing, in particular to insulating personal skin protection equipment (PPE) designed to protect a person from contamination by biological agents contained in the surrounding atmosphere, including viruses.

The utility model can be used in medicine (for example, when servicing patients in outpatient clinics and hospitals, when transporting (evacuating) patients, carrying out disinfection, when taking material from a patient for laboratory research and during autopsy (burial) of corpses), as well as in solving military problems.

An analysis of the existing state of the art in this area showed that many types of personal protective equipment for the skin are known (overalls, protective suits, protective kits, anti-epidemic and anti-plague suits, etc.). The closest in technical essence to the proposed utility model are various insulating suits [patents RU 182942 U1, RU 17432 U1, RU 127318 U1, RU 186358 U1, RU 205454 U1, RU 205498 U1, RU 206395 U1, RU 2755063 C1, RU 58303 U1 , RU 200581 U1, US 3516404, US 4831664, US 4847914, US 2994089, GB 2078491 A, DE 202004019969 U1, US 20120174296 A1, US 6715160, etc.], which differ in design features, materials of execution and methods of their connection (stitching) .

The closest technical result achieved and having a purpose coinciding with the purpose of the claimed utility model (prototype) is "Overalls for protection against pathogenic biological agents" [patent RU 205454 U1], including a jacket with a hood, containing a front, consisting of two shelves, and a back, consisting of two parts, connected by a middle sealed seam, and trousers, fastened to the jacket with a sealed seam. At the same time, the jacket and trousers are made of waterproof polyester fabric with a polyurethane membrane coating on the wrong side and with antistatic thread. Each seam is sealed with a sealing tape. In addition, the coverall retains its original properties after at least ten cycles of regeneration (disinfection, sterilization, cleaning, etc.) by any known method, depending on the materials used in the patented device, i.e. is SIZK reusable.

Despite all the advantages of the prototype device, it has the following disadvantages:

protective shoe covers are not included in the suit and are worn separately, which reduces ease of use and ergonomics;

a straight zipper, fastened at the base of the frontal part of the hood, does not have a high degree of protection against the ingress of pathogenic biological agents into the undersuit space, in particular: firstly, it increases the risk of contaminated air entering the undersuit space due to the formation of a gap in the chin area between a zipper slider and personal respiratory protection equipment; secondly, in the event of malfunctions with a zipper, the suit design does not provide for an alternative zipper that performs barrier functions both in normal and emergency situations;

sleeves with a wide and deep armhole significantly increase the risk of spilling biological samples and chemicals when working at laboratory tables;

the sewn-in finger loops located in the lower part of the one-piece sleeves during prolonged work cause discomfort to the operator, in severe cases, destructive changes in the epithelium (formation of calluses) may occur in the area between the thumb and forefinger of the hand;

due to the very wide cut of the overalls, there is a high probability of the introduction of pathogenic microorganisms into the undersuit space due to the “fur effect”.

The purpose of this utility model is to eliminate these shortcomings, as well as to improve ergonomic characteristics.

When using the utility model, the following technical result is achieved: an increase in the ergonomic properties of SIZK from pathogenic biological agents.

The essence of the utility model lies in the fact that the insulating suit from the SIZK set, made in the form of overalls, consists of a jacket (1) with a hood (2); front (3) consists of two shelves (4), back (5) and trousers (6), fastened to the jacket with a sealed seam. The shelves (4) are fastened with a diagonally located zipper (7), on the inside of which a protective valve (8) is sewn, on the outside the zipper is closed by a valve (9) with a zipper (10), which in turn is closed by a valve (11) fixed on tape-contact (12). Sleeves (13) are set-in double-seam shirt cut, in the lower part of which, with a seam (15), sealed wristlets (14) are sewn to the main material of the sleeve, tied with elastic bands, and a knitted cuff with an opening for the thumb (16) is also sewn with a seam (15) . An extension (20) is sewn over the sleeve (13) with the same seam that is sewn in the forearm area with an elastic tie with a lock-regulator of length (26), in the lower part of which there is a wristband (30), pulled together with a tie of elastic band. The hood (2) is set-in, tailored from the central (19) and two side parts (17), (18), connected by sealed seams. The hood (2) has a built-in elastic cord with a horizontal lock (22). There is a strap (24) on the back of the head of the hood, which allows you to adjust the hood depending on the anthropometric parameters of the head, its length can be changed using a choke buckle. The hood has an elastic band along the obturation line of the front cutout (23). Along the waistline of the suit there is an elastic tie with a length adjuster (25), in the areas of the forearm (26), shoulder (28) and lower leg (29) there are elastic ties with a length adjuster. There are special reinforced pads (27) in the area of knees and elbows. At the bottom of the legs of the trousers (6) there are wristlets (32), pulled together with elastic bands. On top of each trouser leg (6) with the same seam that is sewn in the shin area with an elastic tie with a lock-regulator of length (29), an extension (21) is sewn, in the lower part of which there is a wristband (31), pulled together with a tie of elastic band. All connections of materials (homogeneous and dissimilar) are made by stitching them with sealed seams. All seams must be made using technology that provides protection against the flow of liquid. It is recommended to use an overcast seam (stitch length 3 mm) with a waterproof polyethylene coating.

At the same time, the patented technical solution, in comparison with the known technical solutions of analogues and prototypes, is a design that has the following significant distinguishing features:

1. The insulating suit is made in the form of overalls, the shelves (the front part of the overalls) of which are fastened with a diagonally located zipper, on the inside of which a protective valve is sewn, from the outside the zipper is closed by a valve with a zipper, which in turn is closed by a valve fixed on contact tape.

2. The hood of the insulating suit is set-in, there is an elastic band along the front neckline. To ensure the correct fit and optimal fit of the hood. An elastic cord with a horizontal lock is built into its design. The hood completely covers the forehead, cheeks, neck and chin. There is a strap on the back of the head of the hood, which allows you to adjust the hood depending on the anthropometric parameters of the head by changing the length of the strap using a choke buckle. The design of the hood does not hinder head movement and at the same time ensures its snug fit to personal respiratory protection equipment (PPE).

3. Two-piece set-in sleeves of a shirt cut, in the lower part of the sleeves there are wristlets tightened with elastic bands. With the same seam that sealed wristbands are sewn to the main material of the sleeve, a knitted cuff with an opening for the thumb is sewn from the inside. The last structural element was introduced to exclude the appearance of open areas of the body when manipulating hands in the infected area. On top of the sleeve with the same seam that is sewn in the forearm area with an elastic tie with a lock-regulator of length, an extension is sewn, in the lower part of which there is a wristband pulled together with a tie of elastic band. The extension allows sealing the sleeve-glove connection.

4. In places subject to the risk of mechanical damage and frequent bending (knees, elbows), special reinforced pads are provided, made from a layer of the base material.

The essence of the claimed object is illustrated by drawings (Fig. 1, Fig. 2 and Fig. 3), which show the elements of the insulating suit from the set of SIZK from pathogenic biological agents. In FIG. 1 shows the claimed insulating suit (front view), in Fig. 2 - claimed insulating suit (rear view), in Fig. 3 - section A-A.

The essence of the utility model is related to the achievement of the claimed technical result, respectively, as follows:

1. Improving the ergonomic properties of the patented device is provided by its distinctive features and is achieved due to the fact that the design of the hood for its adjustment to the circumference of the head is provided with an elastic cord with a horizontal lock, there is a strap on the back of the hood that allows you to adjust the hood, which prevents it from falling off on the eyes or be overstretched. The design of the hood does not hinder the movement of the head. The isolation suit is made in the form of a jumpsuit, which makes it easier to put on and take off compared to models where the jacket and trousers are cut separately. The front part of the jumpsuit is fastened with a diagonally located zipper, which is convenient to unfasten and fasten without the help of unauthorized persons. The outer flap of the zipper is fixed to the contact tape, providing ease of fastening, unlike buttons. The use of a knitted cuff with an opening for the thumb provides comfort to the operator during a large number of operations, in particular with small objects. To eliminate the possibility of sagging sleeves and the appearance of a “fur effect” of trousers, elastic ties with a lock-regulator of length were introduced into the design of the suit in the area of the forearm, shoulder and shin, which makes the fit of the overalls as close as possible to the anthropometric parameters of the operator.
