The front part 2 covers the front of the wearer. The pair of sleeve parts 4 are connected to both sides of the front part 2 in the left and right direction. The wearer's arms are inserted into the pair of sleeve parts 4. In the medical gown 1, the area of the front part 2 from the chest to the knees and the area of the pair of sleeve parts 4 from the cuffs to above the elbows are critical zones 5. The critical zone 5 includes a front critical zone 21 and a pair of sleeve critical zones 41. The pair of sleeve critical zones 41 have a higher protective performance level as defined by AAMI than the front critical zone 21. This makes it possible to improve protective performance while suppressing deterioration of comfort when wearing the medical gown 1. As a result, it is possible to simultaneously improve the working environment of medical personnel and suppress exposure to blood and body fluids. [Selected Figure] Figure 1

Description

  The present invention relates to medical gowns.

  Conventionally, in the case of a surgical operation or the like, medical personnel such as doctors and nurses who are involved in the operation wear a sterilized medical gown. When a medical person wears a medical gown, it is possible to protect an easily infected patient from an infection source and prevent the patient's blood, body fluid, and the like from adhering to the medical person's skin.

  For example, in Patent Document 1, a protective glove is placed on a nonwoven fabric of a sleeve of a medical gown for the purpose of preventing a phenomenon in which blood or the like enters from the gap from the sleeve of the medical gown to the wrist side. A technique has been proposed in which a film of polyester elastomer is provided to increase non-stick friction with the protective gloves.

  By the way, the Association for the Advancement of Medical Instrumentation stipulates the protective performance of medical gowns in four stages from the lowest level 1 to the highest level 4. The protective performance level of the medical gown is determined by the protective performance of the critical zone of the medical gown. The protective performance includes, for example, impact permeability, water pressure resistance, virus permeability, blood permeability, and the like. The critical zone is an area from the chest to the knee in the front part of the medical gown and an area from the cuff to the elbow of the pair of sleeves. When the above-mentioned protective performance level is high, the safety of the medical gown increases, but the feeling of wearing the medical gown decreases, for example, the air permeability decreases.

  This invention is made | formed in view of the said subject, and aims at improving protective performance, suppressing the fall of the feeling of wear of a medical gown.

  The invention according to claim 1 is a medical gown, which is a pair of sleeves that are connected to a front portion covering the front surface of the wearer and both left and right sides of the front portion and into which the wearer's arms are inserted. A region from the chest to the knee of the front portion, and a region from the cuff to the elbow of the pair of sleeves is a critical zone, and the critical zone is the American Medical Device Association Includes a first region in which the protection performance level defined by is a predetermined level, and a second region in which the protection performance level is higher than the first region.

  The invention according to claim 2 is the medical gown according to claim 1, wherein the second region is included in each of the pair of sleeve portions.

  The invention according to claim 3 is the medical gown according to claim 1 or 2, wherein the protection performance level of the first region is 3, and the protection performance level of the second region is 4. is there.

  Invention of Claim 4 is a medical gown in any one of Claim 1 thru | or 3, Comprising: The said 2nd area | region is on the outer surface of the sheet member similar to the sheet member which comprises the said 1st area | region. It has a structure in which resin films are laminated.

  In the present invention, it is possible to improve the protective performance while suppressing a decrease in wearing feeling of the medical gown.

It is a front view of the medical gown of the state which the wearer wore. It is a front view of the medical gown of the state which the wearer wore. It is a front view of the medical gown of the state which the wearer wore.

  FIG. 1 is a diagram showing a medical gown 1 according to an embodiment of the present invention. The medical gown 1 is a disposable gown worn by doctors, nurses, and the like during surgery. FIG. 1 is a front view showing the medical gown 1 before wearing in a state where the medical gown 1 is unfolded. In FIG. 1, the medical gown 1 is drawn with the outer surface opposite to the inner surface in contact with the wearer of the medical gown 1 facing forward. FIG. 2 is a front view showing the front side of the medical gown 1 in a state worn by the wearer.

  The medical gown 1 is a gown of a closed type that closes left and right parts on the rear side of the wearer. The medical gown 1 includes a front portion 2, a back portion 3, and a pair of sleeve portions 4. The front part 2 covers the front surface of the wearer. The back part 3 covers a wearer's back. The pair of sleeve portions 4 are connected to both sides of the front surface portion 2 and the back surface portion 3 in the left-right direction. The wearer's arms are inserted into the pair of sleeve portions 4. Each sleeve part 4 covers the site | part from a shoulder part to a wrist among a wearer's arms. A distal end portion 45 of the sleeve portion 4 (that is, a portion closer to the distal end than the cuff) has stretchability and is covered with a glove 6 shown in FIG.

  The front part 2 is a continuous sheet-like part. The front part 2 covers the wearer's throat (that is, the region between the neck and the chest), the chest, the abdomen, the front of the waist, and the front of both legs. In the example shown in FIG. 2, the front surface portion 2 is formed from the wearer's throat, the entire chest region, the abdominal region, the lumbar front surface, and the front surface of both legs from the base of the leg below the knee. Cover all parts.

  The back surface portion 3 includes an inner back surface portion 31 and an outer back surface portion 32. The inner back surface portion 31 extends from the one side of the front surface portion 2 in the left-right direction to the back surface of the wearer and covers the back surface of the wearer. The outer back surface portion 32 extends from the other side of the front surface portion 2 in the left-right direction to the back surface of the wearer. In other words, the outer back surface portion 32 is connected to the side opposite to the side to which the inner back surface portion 31 is connected among the left and right end portions of the front surface portion 2. The outer back surface portion 32 overlaps the inner back surface portion 31 on the rear side of the inner back surface portion 31 and covers the back surface of the wearer. In the example shown in FIG. 1, the inner back surface portion 31 is connected to the front surface portion 2 on the wearer's left side (right side in FIG. 1), and the outer back surface portion 32 is connected to the front surface portion 2 on the wearer's right side.

  The back part 3 covers the back of the wearer, the back of the waist (including the buttocks), and the back of both legs. Specifically, the back surface portion 3 covers substantially the entire back portion of the wearer, the substantially entire back surface of the waist, and the portion of the back surface of both legs that extends from the base of the leg to below the knee.

  When the medical gown 1 is worn, first, both arms of the wearer are inserted into the pair of sleeve portions 4. Then, the inner back part 31 and the outer back part 32 are piled up on a wearer's back. And the inner back surface part 31 and the outer back surface part 32 are fixed by the string etc. which were previously provided in the inner back surface part 31 and the outer back surface part 32 grade | etc.,. Thereby, as shown in FIG. 2, wearing of the medical gown 1 is completed. When the wearing of the medical gown 1 is finished, the gloves 6 are attached to both hands of the wearer. Thereby, the tip part 45 (refer FIG. 1) of each sleeve part 4 of the medical gown 1 is covered with the glove 6 as mentioned above.

  In the medical gown 1, the region 21 from the chest to the knee of the front portion 2 and the region 41 from the cuff to the elbow of the pair of sleeve portions 4 are formed by the Association for the Advancement of the US This is a critical zone defined in Medical Instrumentation (hereinafter referred to as “AAMI”). The critical zone is a region where there is a high possibility that blood, body fluid, or the like adheres, and is a region where relatively high protection performance against blood, body fluid, or the like is required. In the following description, the area 21 of the front face 2 is referred to as “front critical zone 21”, and the area 41 of the sleeve 4 is referred to as “sleeve critical zone 41”. Further, the front critical zone 21 and the sleeve critical zone 41 are collectively referred to as “critical zone 5”. 1 and 2, the front critical zone 21 and the sleeve critical zone 41 are shaded in parallel. The boundary between the front critical zone 21 and the sleeve critical zone 41 and the surrounding area is indicated by a two-dot chain line.

  The protective performance level of the medical gown prescribed by AAMI (hereinafter simply referred to as “protective performance level”) is determined by the protective performance level of the critical zone 5. At level 1, which is the lowest protective performance level, the result of the impact permeability test (AATCC 42 (American Association of Textile Chemist and Colorist 42)) is required to be 4.5 g or less. In Level 2, which is the next highest level of protection performance after Level 1, the impact permeability test (AATCC 42) results in 1.0 g or less, and the water pressure resistance test (AATCC 127 (American Association of Textile Chemist and Colorist 127)) The result is required to be 20 cm or more. At level 3, the next highest level of protection performance after level 2, the impact permeability test (AATCC 42) result is 1.0 g or less, and the water pressure resistance test (AATCC 127) result is 50 cm or more. Is done. Level 4, which is the highest level of protective performance, requires passing a virus penetration test (ASTM F1671 (American Standard Testing Method F1671)) and passing a synthetic blood penetration test (ASTM F1670).

  In the medical gown 1 shown in FIGS. 1 and 2, the protection performance level of the entire front critical zone 21 is 3, and the protection performance level of the entire sleeve critical zone 41 is 4. The medical gown 1 is used, for example, during a procedure in which a wearer's forearm enters a patient's body cavity.

  In the medical gown 1, a region excluding the front critical zone 21 in the front portion 2 (that is, a region above and below the front critical zone 21) and a region excluding the sleeve critical zone 41 in the pair of sleeve portions 4. In other words, the protection performance level of the sleeve critical zone 41 from the shoulder side end portion to the shoulder portion is 1 or more. Further, the protective performance level of the back surface part 3 may be 1 or more, and the level 1 requirement may not be satisfied.

  The front part 2, the back part 3, and the pair of sleeve parts 4 are formed of, for example, a nonwoven fabric or a resin film. The nonwoven fabric is made of, for example, hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.). The front critical zone 21 has, for example, a laminated structure in which a plurality of types of nonwoven fabrics are laminated. The front critical zone 21 is made of, for example, SMMS (spunbond / meltblown / meltblown / spunbond) nonwoven fabric. The sleeve critical zone 41 has, for example, a structure in which a resin film is laminated on the outer surface of a sheet member similar to the sheet member (SMMS nonwoven fabric or the like) constituting the front critical zone 21. The structures of the front critical zone 21 and the sleeve critical zone 41 may be changed as appropriate.

  The region other than the critical zone 5 is formed of, for example, a nonwoven fabric having a single layer structure or a laminated structure. The structure of the area other than the critical zone 5 may be changed as appropriate. In addition, in order to improve the wearing feeling of the medical gown 1, it is preferable that the back surface part 3 has a structure with high air permeability.

  As described above, the medical gown 1 includes the front surface portion 2 and the pair of sleeve portions 4. The front part 2 covers the front surface of the wearer. The pair of sleeve portions 4 are connected to both sides of the front surface portion 2 in the left-right direction. The wearer's arms are inserted into the pair of sleeve portions 4. In the medical gown 1, a region from the chest to the knee in the front portion 2 and a region from the cuff to the upper elbow of the pair of sleeve portions 4 are the critical zone 5. The critical zone 5 includes a front critical zone 21 and a pair of sleeve critical zones 41. The pair of sleeve critical zones 41 has a higher protection performance level defined by AAMI than the front critical zone 21.

  Here, in the critical zone 5, an area where the protection performance level defined by the AAMI is a predetermined level is called a “first area”, and an area where the protection performance level is higher than the first area is called a “second area”. In other words, in the above example, the entire front critical zone 21 is the first region, and the entire sleeve critical zone 41 is the second region. In the medical gown 1, in the critical zone 5, by increasing the protective performance level of the second region where blood or the like is likely to adhere, the blood body fluid exposure of the wearer through the second region is suppressed. Can do. Moreover, the fall of the air permeability of a 1st area | region can be suppressed by making the protection performance level of a 1st area | region lower than a 2nd area | region. Thereby, protective performance can be improved, suppressing the fall of the wearing feeling of the medical gown 1. As a result, it is possible to achieve both improvement of the medical worker's working environment and suppression of blood and body fluid exposure.

  As described above, in the medical gown 1, the protection performance level of the first region is 3, and the protection performance level of the second region is 4. Thereby, a wearer's exposure to a blood body fluid via a 2nd area | region can be suppressed further. The medical gown 1 is particularly suitable for a treatment in which a large amount of blood or body fluid is expected to adhere to the second region.

  The second region has a structure in which a resin film is laminated on the outer surface of a sheet member similar to the sheet member constituting the first region. Thereby, the 2nd field with a high protection performance level can be formed easily, suppressing manufacture of medical gown 1 becoming complicated. As a result, the manufacturing cost of the medical gown 1 can be reduced.

  As described above, in the medical gown 1, the second region having a high protection performance level is the entire pair of sleeve critical zones 41. In this way, by increasing the protective performance level of the sleeve critical zone 41 where the blood or the like is likely to adhere to the surgical field, the blood body fluid exposure of the wearer through the sleeve 4 can be suppressed. it can. Moreover, the fall of the air permeability of the medical gown 1 can be suppressed by making the protective performance level of the front critical zone 21 having a relatively large area ratio in the medical gown 1 lower than that of the sleeve critical zone 41. As a result, it is possible to improve the protective performance while further suppressing the deterioration of the wearing feeling of the medical gown 1.

  In the medical gown 1, the second region having a high protection performance level is not necessarily the entire pair of sleeve critical zones 41. For example, the second region may be included in each of the pair of sleeve portions 4. In the example shown in FIG. 3, in each sleeve critical zone 41, the region 42 from the cuff to the middle part of the wrist and the elbow is the second region, and the region 43 on the shoulder side of the region 42 is the second region. This is the first region with a lower protection performance level. The entire front critical zone 21 is also the first region. In FIG. 3, the boundary between the region 42 and the region 43 is indicated by a two-dot chain line.

  As described above, the second region of the critical zone 5 is included in each of the pair of sleeve portions 4, thereby suppressing the blood body fluid exposure of the wearer via the sleeve portions 4 as described above. And the fall of the breathability of medical gown 1 can be controlled. As a result, it is possible to improve the protective performance while further suppressing the deterioration of the wearing feeling of the medical gown 1.

  In the above-described medical gown 1, various modifications are possible.

  In the example illustrated in FIGS. 1 to 3, the second region is included in each of the pair of sleeve portions 4, but the position of the second region is not limited to these examples. For example, in the medical gown 1 shown in FIG. 1 and FIG. 2, the entire pair of sleeve critical zones 41 is a first region having a protection performance level of 3, and the entire front critical zone 21 is a first region having a protection performance level of 4. There may be two regions. Further, in the medical gown 1 shown in FIG. 3, the entire front critical zone 21 may be the second region having the protection performance level 4 in addition to the region 42 of each sleeve critical zone 41.

  In the medical gown 1, as shown in FIG. 4, in the front critical zone 21, the region 22 from the chest to the waist is the second region having a protection performance level of 4, and the region 23 from the waist to the knee is The first region may have a protection performance level of 3. Alternatively, the area 22 of the front critical zone 21 may be a first area having a protection performance level of 3, and the area 23 may be a second area having a protection performance level of 4. In any case, the entire pair of sleeve critical zones 41 may be a first region with a protection performance level of 3 or a second region with a protection performance level of 4.

  In the medical gown 1, the pair of sleeve critical zones 41 may include a first region and a second region, respectively, and the front critical zone 21 may also include a first region and a second region. In the example shown in FIG. 5, in each sleeve critical zone 41, one of a region 42 from the cuff to the middle portion of the wrist and the elbow and a region 43 on the shoulder side of the region 42 is the protective performance level. Is a first region with 3 and the other region is a second region with a protection performance level of 4. In the front critical zone 21, one of the region 22 from the chest to the waist and the region 23 from the waist to the knee is the first region with the protection performance level 3, and the other region is the protection performance. This is the second area whose level is 4.

  In the medical gown 1, the protection performance level of the first region is not limited to 3, and the protection performance level of the second region is not limited to 4. For example, the protection performance level of each of the first region and the second region may be 2 and 4, or 2 and 3.

  That is, in the medical gown 1, if the critical zone 5 includes a first area where the protection performance level defined by AAMI is a predetermined level, and a second area where the protection performance level is higher than the first area. Good. Thereby, a protective performance can be improved like the above, suppressing the fall of the wearing feeling of the medical gown 1. As a result, it is possible to achieve both improvement of the medical worker's working environment and suppression of blood and body fluid exposure.

  The medical gown 1 may have various configurations in addition to the configuration described above. For example, the medical gown 1 may include a mask portion that extends upward from the upper end edge of the front surface portion 2 located at the throat of the wearer and covers the lower half of the wearer's face.

  The structure according to the critical zone 5 of the medical gown 1 described above may be applied to a pre-closed type medical gown that closes left and right parts on the front side of the wearer. The medical gown includes, for example, a continuous sheet-like back surface portion, a front surface portion (that is, an inner front surface portion and an outer front surface portion) that extends from the left and right sides of the back surface portion to the wearer's front surface, and a front surface portion. And a pair of sleeves connected to both sides of the back portion in the left-right direction. Even in this case, the protective performance can be improved while suppressing a decrease in the wearing feeling of the medical gown.

  The configurations in the above-described embodiments and modifications may be combined as appropriate as long as they do not contradict each other.
