Description

The present invention relates to disposable protective clothing used by medical staff treating infected patients for the purpose of preventing infection.

During large-scale outbreaks of infectious diseases, as seen with the global spread of the new coronavirus in 2020, medical staff who must treat infected patients wear shower caps, masks, and vinyl gloves. In addition, efforts should be made to prevent infection from patients by wearing protective clothing.

Furthermore, in the event of a serious epidemic where there are concerns that the medical system may collapse, it may not be possible to simply hospitalize patients while symptoms are still mild, and family members may have to care for them at home. In such cases, it is preferable that family members caring for infected patients wear protective clothing in the same way as medical staff, to prevent the spread of infection among family members.

In addition, as prior art document information related to this type of protective clothing, there are, for example, the following Patent Documents 1 and 2.

JP 2005-2545 A Utility model registration No. 3141379

However, this type of protective clothing does not simply mean that the wearer will not be infected by the patient; it is important to properly change into new protective clothing and discard it one after another, so that there is no risk of infection to others through the protective clothing. It is necessary to prevent

In other words, the areas where a patient coughs or the areas they come in contact with during nursing become contaminated with viruses, and there is a possibility that viruses and bacteria may adhere to the surface of protective clothing even if it is invisible. Therefore, if you enter another hospital room while wearing the same protective clothing after caring for an infected patient, you run the risk of contaminating that room as well.

For this reason, if there is enough inventory, protective clothing needs to be taken off and put on many times and then thrown away. It is necessary to be able to respond quickly to the increasing demand, and it is also necessary to reduce the cost per sheet as much as possible to reduce the economic burden.

For example, the protective clothing described in Patent Documents 1 and 2 listed above is in the form of a coverall that combines a jacket and pants, and has zippers on the front and back sides. They are designed to be put on and taken off by opening and closing them, but this type of coverall requires a lot of effort to put on and take off, and is not suitable for use where the clothes are to be taken off and put on repeatedly and then thrown away.

Moreover, these coveralls are not easy to sew, making it difficult to quickly respond to sudden increases in demand during large-scale infectious disease outbreaks, and the cost per piece is high.

The present invention was made in consideration of the above-mentioned circumstances, and aims to provide disposable protective clothing that is easy to put on and take off, easy to manufacture, can be quickly adapted to sudden increases in demand, and can be manufactured at low cost, reducing the economic burden.

The present invention is a disposable protective clothing used to prevent infection, and includes a single torso part cut in a single stroke shape from a nonwoven fabric sheet and a pair of sleeve parts, the torso part being , a neck cutout whose upper end part passes through the wearer's head when folded back so that the center part forms the back body that covers the wearer's back side, and the both sides form the front body that covers the wearer's front side. The sleeves are sewn to form a front-opening gown shape that wraps around the wearer's shoulder to leg area from the back side to the front side. The parts are sewn into the armholes of the torso part in a state where they are stitched together into a cylindrical shape to form sleeves that cover the arms of the wearer. A fastener is provided for binding the front body part together, and a pair of waist straps are provided at the midway point of the torso part to wrap around the wearer's torso. The attachment end of the waist strap is sewn in a state of being folded in half at the middle in the width direction .

Therefore, when wearing the protective clothing constructed in this way, the wearer puts both arms through each sleeve part, puts on the torso part, and wraps the torso part from the back side to the front side. By stacking the left and right front pieces like a gown and tying them with a waist strap, and binding the left and right front pieces together using the clasp at the neck opening, you can easily cover the area from the wearer's arms and shoulders to the legs. The protective clothing will be covered with protective clothing, and after use, the protective clothing can be easily taken off by removing the clasp at the neck opening and untying or tearing off the knots of each waist strap.
In addition, the attachment end of the waist strap is sewn to the midway part of the torso part while being folded in half at the middle in the width direction, so the part of the waist strap sewn to the midway part of the torso part is strong. This makes it less likely that the waist strap will be unintentionally damaged during use.

In addition, in the present invention, it is preferable that the fastener at the neck cutout of the torso part is a hook-and-loop fastener, and that the fastening position of the hook-and-loop fastener can be changed in the circumferential direction of the neck cutout. In this way, it is possible to fasten the left and right front body pieces together at the neck cutout with a single touch, and it is also possible to change the fastening position of the hook-and-loop fastener to match the size of the wearer's neck and eliminate gaps in the neck cutout.

Furthermore, in the present invention, it is preferable that the cuffs of the sleeve parts are configured to be freely expandable and contractible by sewing on elastic tape and gathering, so that it is possible to narrow the cuffs to fit the size of the wearer's wrist and eliminate gaps.

According to the above-mentioned protective clothing of the present invention, various excellent effects as described below can be achieved.

(I) The wearer can easily put on the protective clothing through extremely simple actions: put both arms through each sleeve part, put on the torso part, roll the torso part from back to front, overlap the left and right front parts like a gown, tie them with a waist cord, and fasten the left and right front parts together with a fastener at the neck opening. Moreover, the suit can be easily taken off by removing the fastener at the neck opening and undoing or tearing off the knots of the waist cords, making it very easy to put on and take off as a disposable protective clothing.

(II) The torso and sleeve parts that make up the protective clothing can be cut in one continuous stroke from a nonwoven fabric sheet, significantly shortening the cutting time. The torso and sleeve parts can then be easily sewn together into protective clothing in just a few steps, significantly simplifying the production of protective clothing and allowing for a rapid response to sudden increases in demand during large-scale infectious disease outbreaks. Moreover, the fact that the clothing can be produced from a nonwoven fabric sheet minimizes the cost per piece, significantly reducing the economic burden of disposable clothing.

(III) If the fastener at the neck cutout part of the torso part is a hook-and-loop fastener, and if the binding position of the hook-and-loop fastener can be changed in the circumferential direction of the neck cutout part, the left and right front bodies can be attached to the neck cutout part. It can be stitched together with one touch, making it even easier to put on and take off. Furthermore, the stitching position of the hook-and-loop fastener can be changed to match the size of the wearer's neck, eliminating the gap at the neck opening to prevent infection. The effect can be increased.

(IV) If the cuffs of the sleeve parts are made expandable and contractible by sewing elastic tape and gathering, the cuffs can be narrowed to fit the size of the wearer's wrist, eliminating gaps and improving infection prevention.

(V) If you adopt a configuration in which the attachment end of the waist strap is folded in half at the middle of the width direction and sewn to the midway part of the torso part, the part of the waist strap sewn to the midway part of the torso part will be strong. As a result, it is possible to prevent the waist strap from being unintentionally damaged during use.

Embodiments of the present invention will be described below with reference to the drawings.

Figures 1 to 8 show an example of a form for implementing the present invention, which relates to disposable protective clothing 1 to be worn by medical staff treating infected patients to prevent infection. As shown in the front view of Figure 1 and the back view of Figure 2, the clothing is equipped with a single torso part 2 and a pair of sleeve parts 3 cut in a single stroke from a nonwoven fabric sheet that has been subjected to general reinforcement. The torso part 2 is folded back so that its central part forms a back body part 2a that covers the back side of the wearer and both sides form front body parts 2b, 2c that cover the front side of the wearer, with the upper end part covering the wearer's head. The sleeve parts 3 are sewn together leaving only the neck opening 4 and the armholes 5 through which the garment is passed, forming a gown that opens in the front and wraps around the wearer's shoulders to the front to cover the wearer's legs. The sleeve parts 3 are sewn together in a cylindrical shape to form sleeves that cover the wearer's arms and are then sewn to the armholes 5 of the torso part 2. The neck opening 4 of the torso part 2 is equipped with a hook-and-loop fastener 6 as a fastener for fastening the left and right front body parts 2b, 2c together, and the middle of the torso part 2 is equipped with a pair of waist strings 7, 8 for wrapping and tightening around the wearer's waist.

The state of the torso part 2 before it is used as a front-opening gown is as shown in the development diagram in Figure 3, where both sides of the torso part 2 are folded inward along fold line A in the development diagram in Figure 3 to form the front body parts 2b and 2c, and the upper ends of each are sewn together leaving behind the neck opening 4 and armholes 5, while the hook-and-loop fastener 6 and waist strings 7 and 8 are separately sewn onto the torso part 2 and attached.

As shown enlarged in FIG. 4, the hook and loop fastener 6 is composed of a hook surface 6a that is raised to form a hook shape and a loop surface 6b that is raised to form a loop shape, with the hook surface 6a sewn to the front side of the neck opening 4 of the front body 2b (the front body on the left side in FIG. 1) that will be layered underneath, and the loop surface 6b sewn to the back side of the neck opening 4 of the front body 2c (the front body on the right side in FIG. 1) that will be layered on top. In the example shown here, the hook surface 6a is formed relatively longer around the neck than the loop surface 6b, so that the binding position of the hook and loop fastener 6 can be changed in the circumferential direction of the neck opening 4.

The waist strings 7, 8 are sewn to the front end of the front body 2c and to the right side of the back body 2a (see Figure 2) so that the front body 2c can be tied and fixed near the wearer's right side when the front body 2b is overlaid on top of the front body 2b.

In addition, while FIG. 5 only shows the waist cord 8, the attachment end of the waist cord 8 is folded in half at the middle in the width direction and sewn to the middle of the front body 2c, while the attachment end of the waist cord 7 sewn to the middle of the front body 2b (not shown in FIG. 5) is also folded in half at the middle in the width direction and sewn to the middle of the front body 2b.

Furthermore, the state of the sleeve part 3 before it is sewn to the armhole 5 to form the sleeve is as shown in the development diagram in Figure 6. The sleeve part 3 is folded back along the fold line B in the development diagram in Figure 3 and stitched together into a tube to form the sleeve, and the cuff 9 is made to be freely expandable and contractible by sewing on the elastic tape 10 and gathering 11.

When the protective suit 1 thus constructed is worn, the wearer puts both arms through the sleeve parts 3, puts on the torso part 2, rolls the torso part 2 from the back side to the front side, overlapping the front body part 2c over the front body part 2b, and fastens and secures both parts with the waist strings 7, 8 near the wearer's right side. The left and right front body parts 2b, 2c are fastened together with the hook-and-loop fastener 6 at the neck opening 4. As shown in FIG. 8, the protective suit 1 easily covers the wearer's arms and the area from the shoulders to the feet. After using the protective suit 1, the wearer can easily take it off by removing the hook-and-loop fastener 6 at the neck opening 4 and undoing or tearing off the knots of the waist strings 7, 8.

In this case, a hook-and-loop fastener 6 is used as a fastener in the neck cutout 4 of the torso part 2, and the fastening position of the hook-and-loop fastener 6 can be changed in the circumferential direction of the neck cutout 4, so that the left and right front body parts 2b, 2c can be fastened together at the neck cutout 4 with one touch, and the fastening position of the hook-and-loop fastener 6 can be changed to match the size of the wearer's neck and eliminate gaps in the neck cutout 4. Moreover, the cuffs 9 of the sleeve parts 3 are freely expandable and contractible due to the sewing of elastic tape 10 and gathering 11, so that the cuffs 9 can be narrowed to match the size of the wearer's wrist and eliminate gaps.

Accordingly, according to the above embodiment, the wearer can easily don the protective suit 1 with extremely simple actions: put both arms through the sleeve parts 3, put on the torso part 2, roll the torso part 2 from the back side to the front side, overlap the left and right front body parts 2b, 2c like a gown, tie them with the waist strings 7, 8, and fasten the left and right front body parts 2b, 2c together with the hook-and-loop fastener 6 at the neck opening 4. Moreover, the protective suit 1 can be easily taken off by removing the hook-and-loop fastener 6 at the neck opening 4 and undoing or tearing off the knots of the waist strings 7, 8, so that the protective suit 1 can be put on and taken off very easily as a disposable protective suit.

In addition, the torso part 2 and each sleeve part 3 that make up the protective suit 1 can be cut in one continuous stroke from a nonwoven fabric sheet, significantly shortening the cutting time, and then the torso part 2 and each sleeve part 3 can be easily sewn together into the protective suit 1 in just a few steps, significantly simplifying the production of the protective suit 1 and allowing for a rapid response to sudden increases in demand during large-scale epidemics of infectious diseases. Moreover, by being produced from a nonwoven fabric sheet, the cost per piece can be kept to a minimum, significantly reducing the economic burden of disposable clothing.

Furthermore, by using a hook-and-loop fastener 6 as a fastener in the neck cutout 4 of the torso part 2 and configuring the fastening position of the hook-and-loop fastener 6 to be changeable in the circumferential direction of the neck cutout 4, the left and right front body parts 2b, 2c can be fastened together at the neck cutout 4 with a single touch, making it even easier to put on and take off. Moreover, by changing the fastening position of the hook-and-loop fastener 6 to suit the size of the wearer's neck, it is possible to eliminate gaps in the neck cutout 4, thereby improving the infection prevention effect.

In addition, the cuffs 9 of the sleeve parts 3 are made expandable and contractible by sewing on elastic tape 10 and gathering 11, so the cuffs 9 can be narrowed to fit the size of the wearer's wrist and eliminate gaps, further enhancing the infection prevention effect.

Furthermore, the attachment ends of the waist cords 7, 8 are folded in half at the widthwise center and sewn to the middle of the torso part 2, so that the sewn portions of the waist cords 7, 8 to the middle of the torso part 2 are strong, making it difficult for the waist cords 7, 8 to be damaged unintentionally during use.

The protective clothing of the present invention is not limited to the above-mentioned embodiment, and fasteners other than hook-and-loop fasteners may be used, and various other modifications may of course be made without departing from the spirit of the present invention.
