Description

  The present invention relates to a surgical gown worn by a doctor or the like during surgery.

  2. Description of the Related Art Conventionally, a medical staff such as a doctor generally wears a surgical gown that is sufficiently sterilized and sterilized in order to ensure a clean area on the body surface during surgery. This surgical gown needs to maintain the cleanliness by preventing infection with bacteria and viruses at the time of surgery, so it needs to have a barrier against body fluids and bacteria / viruses carried along with the body fluids. Become. And the higher the barrier property, the lower the risk of infection, so the cleanliness can be maintained well. Therefore, recently, a fabric having a higher barrier property has been demanded as a fabric for a surgical gown.

JP 2002-220712 A

  However, fabrics with high barrier properties have the advantage of being able to block body fluids and the accompanying bacteria, etc., and can block them. However, there is a demerit that heat and moisture are easily trapped in the surgical gown. For this reason, when a surgical gown made of only a fabric having a high barrier property is used for surgery, the physical and mental health of the wearer is increased due to an increase in temperature and humidity in the surgical gown. There was a risk that the surgical stress would be great and hinder the operation.

  Therefore, the present invention is intended to solve the above-mentioned problems, and it is possible to prevent infection during the operation and keep the clean area well, and it is difficult for heat and moisture to remain inside during the operation. The aim is to obtain a surgical gown that can reduce the burden.

  In order to solve the above-described problems, the present invention provides a surgical gown including a body body composed of a front body and a back body, and both sleeves extending from both sides of the body body. In addition, a part or all of both sleeves are formed of a sheet having a three-layer structure in which a film is sandwiched between two layers of fabric, and the back body is formed of a knitted fabric.

  In this way, a film is sandwiched between two layers of fabric, part or all of the front body and parts or all of both sleeves that are likely to come into direct contact with substances that may be infected, such as body fluids and bacteria. By forming with a sheet having a three-layer structure, the barrier property is increased and the risk of infection in a region where there is a risk of infection can be reduced, and the cleanliness can be maintained well.

On the other hand, when the back body is formed of a knitted fabric, the air permeability becomes good and it becomes difficult for heat and moisture to stay in the surgical gown, so that the burden on the wearer can be reduced.
As for the back body, unlike the front body and both sleeves, there is little risk of infection such as body fluids and bacteria, so even if this back body is formed with knitted fabric, there is little risk of increasing the risk of infection. .

  The back body consists of a right back body that is continuous to the right side of the front body and a left back body that is continuous to the left side of the front body, and a part or all of the right back body and the left back body are overlapped. You may wear in a state. In this way, the wearer bends the waist at the mating portion between the right back body and the left back body of the wearer by wearing a part of or all of the right back body and the left back body. Even if the posture is changed, the unclean part of the wearer becomes difficult to be exposed during the operation. Therefore, the wearer's cleanliness can be maintained and the wearer can be given a sense of security.

  Further, the sheet having a three-layer structure may be formed by sandwiching a film between two layers of knitted fabric.

  As described above, the present invention provides a film covering part or all of the front body, which may be in direct contact with a substance that may be infected, such as body fluids or bacteria, and part or all of both sleeves between two layers of fabric. It is formed by a sheet having a three-layer structure sandwiched between two layers. Therefore, the barrier property of the front body and both sleeve portions having a high infection risk is increased, and the infection risk can be reduced and the clean area can be well maintained. In addition, by forming the back body with a relatively low risk of infection with knitted fabric, the air permeability of the back body is improved, and heat and moisture are less likely to be trapped in the surgical gown. It becomes possible to reduce.

  Referring to Embodiment 1 of the present invention, (1) is a body body, and the surgical gown of Embodiment 1 is the body body (1) and both sleeves (2) extending from both sides of the body body (1). ) (3). The body (1) is composed of a front body (4) and a back body (5) as shown in FIGS. 1 and 2, and the back body (5) has a right back body (6) and a left back body (7). ).

  The right back body (6) is continuous from the right side (8) of the front body (4), and the left back body (7) is continuous from the left side (10) of the front body (4). . Also, the right back body (6) and the left back body (7) are formed by overlapping the parts as shown in FIG. The right back body (6) and the left back body (7) are fixed and worn by tying them at two places on the waist. Even when the wearer changes his / her posture by bending his / her waist by wearing a part of or all of the right back body (6) and the left back body (7), Since the wearer's dirty part is difficult to be exposed during the operation in the mating part (12) where the wearer's right back body (6) and left back body (7) are overlapped, the wearer is kept clean. While being able to hold | maintain, a wearer can be provided with a sense of security.

  Both sleeves (2) and (3) have a length that allows covering from the shoulder to the wrist of the wearer, and the sleeve tips (13) and (14) are formed of a stretchable material that can be stretched. By placing this stretch material in close contact with the wrist of the wearer, it is possible to prevent body fluid from entering the sleeves (13) (14) into the sleeves (13) (14) and maintain cleanliness.

  Further, the fabric constituting the front body (4), the back body (5), and the sleeves (2) (3) is different for each part. That is, in this embodiment, the most suitable body for preventing infection is partially used for the front body (4) and both sleeves (2) and (3) where the risk of infection is high, and the risk of infection is relatively low. The back body (5) is made of a fabric with good ventilation. In addition, the other portions are made of water-repellent fabric.

  The fabric constituting each part will be described in detail. In the front body (4), as shown in FIG. 2, the fabric is different between the part above the chest (15) and the part below the chest (15). That is, the portion above the chest (15) is formed using a fabric (16) having a water repellency of 100% polyester. On the other hand, the lower part of the chest (15) is formed of a sheet (17) having a three-layer structure in which a film formed of polyurethane resin is sandwiched between two layers of polyester knitted fabric.

  Furthermore, both sleeves (2) and (3) are the same three layers as those using the front side (20) and (21) of the sleeve (2) and (3) below the chest (15) of the front body (4). Fabric (16) formed with a sheet of structure (17) and using the proximal side (22) (23) of the sleeve (2) (3) above the chest (15) of the front body (4) It is formed with the same fabric (16).

  The three-layered sheet (17) used in the front body (4) and both sleeves (2) and (3) has a barrier performance such as a surgical gown defined by AAMI (Association for the Advancement of Medical Instrumentation). Among the levels, the level 4 with the highest level is satisfied. This level 4 standard means that it has reached a level that can block the penetration of the liquid and the invasion of the virus, such as the front body (4) and both sleeves (2) (3). This is an indispensable level for preventing infection at sites that may come into contact with viruses, bacteria, and the like.

  Therefore, as described above, in the front body (4) and both sleeves (2) (3), the part with high infection risk is formed with the fabric that satisfies the level 4 standard, thereby increasing the barrier property at the time of surgery. The risk can be reduced and the cleanliness can be maintained well, and the operation can be proceeded smoothly.

  The back body (5) is formed of a polyester knitted fabric (18). And for this back body (5), it is common practice to wear the right back body (6) and the left back body (7) as described above, but as described above, the back body ( By forming 5) with knitted fabric (18), it is possible to maintain good air permeability even if they are double stacked, and it is difficult for heat and moisture to accumulate in the surgical gown. It becomes possible to reduce the burden. Unlike the front body (4) and both sleeves (2) and (3), the back body (5) has a low risk of infection, so even if it is formed on the knitted fabric (18), the risk of infection may increase. It is thought that there are few things.

  Here, in order to verify the comfort of the back body (5) in the clothes, a heat retention test of the clothes was performed, and changes in temperature and humidity in the clothes over time were examined. As a comparative example of Example 1, a surgical gown having the same pattern as that of Example 1 and having the same material as that of Example 1 except for the back body was used. The back body of this comparative example was made of a 100% polyester fabric used in the back body of a conventional surgical gown.

First, the test method of the heat retention test will be described below. For this heat retention test, a KES-F7 Thermolab II tester manufactured by Kato Tech Co., Ltd. was used.
Then, on a hot plate set at an environmental temperature of + 10 ° C., set a test piece formed by cutting out the fabric of each part of Example 1 and Comparative Example, and the amount of heat (a) dissipated through this test piece. While calculating, the amount of heat (b) dissipated without setting the test piece was obtained, and the heat retention rate (%) was calculated according to the following formula.
Thermal insulation rate (%) = (1-ab) × 100

  The results calculated by this mathematical formula are shown in Table 1 below.

  From the results shown in Table 1, the rear body of the comparative example had a higher heat retention rate than other parts because the polyester fabric was doubled. In contrast, since the back body (5) of Example 1 is formed of the knitted fabric (18), even if it is a double-layered structure, the heat retention rate is lower than other parts. It was. Further, when the heat retention rate of the back body (5) of Example 1 and the back body of the comparative example were compared, it was found that the heat retention rate of the back body (5) of Example 1 was much lower.

  Next, the test of the change over time of the temperature and humidity in the clothes performed using the sweating thermal manikin will be described below. First, the sweating thermal mannequin used in the test is a sweating thermal mannequin manufactured by MEASUREMENT Technology NORTH WEST. .

  In addition, sensors that can detect temperature and humidity were fixedly arranged at two places on the chest and the back of the sweating thermal manikin. The sweating thermal mannequin in which the sensor was arranged was worn with the surgical gown of Example 1 or the comparative example as described above, and wind was continuously applied from the rear of the sweating thermal mannequin toward the back for 50 minutes. The wind speed was set to 0.3 m / s or less from the start of measurement to 20 minutes, and then the wind speed was set to 2.0 m / s from 20 minutes to 50 minutes.

  Then, while increasing the sweating amount of the sweating mannequin to 100 g / m 2 per hour from the start to the end, the temperature and humidity of the chest and back of the sweating mannequin were measured over time. The measurement environment was 20 ° C. and 40% RH. The measurement results are shown in FIGS.

  FIG. 4 is a graph showing the temperature change in the clothes on the back side of the sweating thermal mannequin, where the solid line wears the surgical gown of Example 1 and the dotted line wears the surgical gown of the comparative example Represents the temperature. And from this graph, since a slight wind of 0.3 m / s or less was applied for 20 minutes from the start of measurement, there was no significant difference between the two. Further, from 20 minutes to the end of the measurement, the comparative example showed a value about 2 ° C. lower than that of Example 1.

  FIG. 5 is a graph showing the temperature change in the clothing on the chest side of the sweating thermal mannequin, where the solid line wears the surgical gown of Example 1 and the dotted line wears the surgical gown of the comparative example Represents the temperature. From this graph, as in the case of the back side, there was no significant difference between the two from the start of measurement until 20 minutes. However, from 20 minutes to the end of the measurement, the temperature of Example 1 was lower than that of the comparative example, and the difference greatly increased to 7 ° C. or more.

  FIG. 6 is a graph showing the humidity change in the clothes on the back side of the sweating thermal mannequin, where the solid line wears the surgical gown of Example 1 and the dotted line wears the surgical gown of the comparative example Represents the humidity. From this graph, the humidity value of the comparative example was about 10% lower than that of Example 1 in 20 minutes from the start of measurement. From 20 minutes to the end of the measurement, the value of Example 1 was higher than that of Comparative Example. However, the humidity was about 30% lower.

  FIG. 7 is a graph showing the humidity change in the chest-side clothing of the sweating thermal mannequin, where the solid line wears the surgical gown of Example 1 and the dotted line wears the surgical gown of the comparative example Represents the humidity. From this graph, the humidity of Example 1 was lower than that of the comparative example from the start of measurement to the end of measurement. In particular, the humidity of Example 1 significantly decreased after 20 minutes from the start of measurement, while the humidity in the comparative example tended to increase continuously.

  Table 2 shows the temperature and humidity of the chest and back of Example 1 and the comparative example at the time 20 minutes after the start of measurement and at the end of the measurement (after 50 minutes from the start of measurement), and the average value thereof.

  Explaining Table 2, 20 minutes after the start of measurement when the temperature was highest, the chest of Example 1 was 33.3 ° C. and the back was 30.8 ° C., and the chest of the comparative example was 31.5 ° C. and the back was 32.5 ° C. The temperature at the end of the measurement was 26.1 ° C. for the chest of Example 1, 29.0 ° C. for the back, 31.2 ° C. for the chest of the comparative example, and 28.2 ° C. for the back.

  When the chest and back temperatures of Example 1 and Comparative Example were averaged, in Example 1, the average 20 minutes after the start of measurement was 32.1 ° C., and the end of measurement was 27.6 ° C. From this result, it became clear that the temperature dropped by an average of 4.5 ° C. from 20 minutes after the measurement until the end of the measurement. In the case of the comparative example, the average 20 minutes after the start of the measurement was 32.0 ° C., and the end of the measurement was 29.7 ° C. From this result, it became clear that the temperature dropped by an average of 2.3 ° C. from 20 minutes after the measurement until the end of the measurement. From the above, it was revealed that the surgical gown of Example 1 had about twice as high a decrease in the temperature in the clothes as compared with the comparative example.

  Next, regarding the humidity, 20 minutes after the start of measurement when the humidity in the clothes was highest, the chest of Example 1 was 64.8%, the back was 86.6%, the comparative example was 91.2%, and the back was 80.3%. . The humidity at the end of the measurement was 22.4% for the chest of Example 1, 26.4% for the back, 98.8% for the comparative example, and 65.0% for the back.

  When the breast and back humidity in Example 1 and Comparative Example were averaged, in Example 1, the average 20 minutes after the start of measurement was 75.7%, and the end of measurement was 24.4%. From this result, it became clear that the humidity dropped significantly to an average of 51.3 points from the 20 minutes after the measurement until the end of the measurement. In the comparative example, the average 20 minutes after the start of measurement was 85.8%, and the end of measurement was 81.9%. From this result, it became clear that the humidity decreased by an average of only 3.9 points from the 20 minutes after the measurement until the end of the measurement. From the above, it has been clarified that the surgical gown of Example 1 can significantly reduce the humidity in the clothes under the wind speed of 2.0 m / s than that of the comparative example.

  From this result, even if the back body (5) of Example 1 has a double-layered structure, it is easy to release internal heat and moisture by forming it with the knitted fabric (18). It was confirmed that the comfort can be improved. Therefore, heat and moisture are less likely to be accumulated in the surgical gown, and the burden on the wearer such as a doctor can be reduced.
