Description

  The present invention relates to a rubber glove used by workers and the like during surgery and a method for manufacturing the same.

  Conventionally, rubber gloves for surgery have been used to protect workers and the like from infectious disease viruses during surgery (see, for example, Patent Document 1). Since this rubber glove for surgery has an important role of protecting workers and the like, it is required to have excellent mechanical properties that are free from pinholes and have excellent barrier properties and that are not easily damaged during surgery. In addition, conventional surgical rubber gloves are formed of white rubber as a whole in consideration of hygiene and the like, and are substantially composed of the same color (Non-Patent Document 1). Three-layered powder-free surgical rubber gloves with nitrile coating on the inner surface are also known, but each layer of the three-layered structure is almost the same color, so even if the outer layer is scratched, the damage is visually recognized. It was difficult.

It is a flowchart which shows embodiment of the manufacturing method of the surgical glove which concerns on this invention.

  1 and 2 show an embodiment of a surgical glove 1 according to the present invention. The surgical glove 1 includes a palm portion 2 and a forearm portion 3, the palm portion 2 includes a five-finger portion, and the forearm portion 3 includes a cuff portion 4 at the end thereof. The surgical glove 1 is entirely made of natural rubber, and uses sulfur (vulcanizing agent) and bisphenol-based chemicals (anti-aging agent) as compounding chemicals. The wall thickness of the surgical glove 1 is set to 0.13 mm to 0.22 mm. Also, no powder is used (powder free).

  The palm portion 2 includes, for example, a white second color rubber layer R2 (natural rubber) formed on the inner surface side thereof and, for example, a brown first color rubber formed integrally on the outer surface of the second color rubber layer R2. It is a two-layer structure provided with a layer R1 (natural rubber), and the first color and the second color are different colors that can be easily distinguished visually even when dyed with blood or not. As a result of the test, a clear distinction was made between brown and white.

  The forearm 3 has a single layer structure composed of a second color rubber layer R2 formed integrally with the second color rubber layer R2 of the palm 2. Here, “forearm 3” refers to the range from the wrist to the lower part of the elbow.

  In addition, the outer surface of the palm portion 2 (the outer surface of the first color rubber layer R1) and the outer surface of the forearm portion 3 (the outer surface of the second color rubber layer R2) have a fine rough surface 10a existing on the outer surface of the hand mold 10. A fine rough surface S formed by the above is formed. The fine rough surface S is formed by fine innumerable irregularities in units of microns. The fine rough surface S can be formed only on the outer surface of the palm 2.

  Furthermore, the cuff part 4 which formed the terminal part of the said forearm part 3 by what is called a roll end process in the terminal part of the forearm part 3 is formed. In addition, although the surgical glove 1 in this embodiment is provided with the cuff part 4, this invention also includes the surgical glove which does not have the said cuff part 4. FIG.

  Although the fine rough surface S of the surgical glove 1 in the present embodiment is formed by the fine rough surface 10a existing on the outer surface of the hand mold 10, the present invention is not limited to this. It can also be formed by adding other steps.

  The surgical glove 1 according to the present embodiment can be manufactured by the steps shown in FIGS. A flowchart of such a manufacturing process is shown in FIG. In the manufacturing method of the present embodiment, the hand mold 10 having at least the palm mold section 11 and the forearm mold section 12 and having the fine rough mold surface 10a on the outer surface is used. The hand mold 10 is made of ceramic.

  First, the hand mold 10 is in a downward state (a state where the fingertip is directed downward), and by lowering, only the palm part 11 of the hand mold 10 is immersed in the first color rubber liquid L1 stored in the first container C1. (FIG. 3A). And after immersing for a fixed time, by pulling up, 1st color rubber layer R1 is formed in the outer surface of the palm-type part 11 (1st immersion process P1) (FIG.3 (b)). Instead of moving the hand mold 10 up and down, the container C containing the first color rubber liquid L1 can be moved up and down.

  Next, the first color rubber layer R1 formed on the palm mold part 11 of the hand mold 10 is brought into a dry state (drying process P2). The drying step P2 can use natural drying in which the first color rubber layer R1 is exposed to the air, or can use mechanical drying such as blowing air K as shown in FIG. 4 (FIG. 4). ).

  Subsequently, by lowering the hand mold 10 again, both the palm mold section 11 and the forearm mold section 12 are dipped in the second color rubber liquid L2 accommodated in the second container C2 for a predetermined time and then pulled up (FIG. 5 (a)). Thus, the second color rubber layer R2 is formed on the outer surface of the first color rubber layer R1 of the palm mold portion 11 and the outer surface of the forearm mold portion 12 (FIG. 5B). (Second immersion step P3).

  Next, the first color rubber layer R1 and the second color rubber layer R2 formed on the outer surface of the hand mold 10 are vulcanized by heating H, for example, as shown in FIG. 6 (vulcanization step P4). By this vulcanization step P4, properties unique to the rubber material such as elasticity are imparted to the first color rubber layer R1 and the second color rubber layer R2.

  Then, the first color rubber layer R1 and the second color rubber layer R2 formed on the outer surface of the hand mold 10 are removed while turning over from the hand mold 10 (reverse removal process P5) (FIG. 7A). By this reverse removal process P5, the first color rubber layer R1 that is in contact with the hand mold 10 and covered with the second color rubber layer R2 appears on the outer surface, and approximately half of the second color rubber layer R2 (the palm portion 2 is removed). The constituent part) is covered with the first color rubber layer R1, and the remaining part (part constituting the forearm part 3) appears on the outer surface (FIG. 7B).

  The surgical glove 1 provided with the palm part 2 and the forearm part 3 described above is manufactured by the plurality of steps described above. In the present embodiment, the roll end step P6 is further added to wind the end portion of the forearm portion 3 to form the roll-shaped cuff portion 4. The roll end process P6 can be performed prior to the vulcanization process P4 or can be performed after the vulcanization process P4 (see FIG. 8).

  The manufacturing method of the surgical glove which concerns on this embodiment is the 1st immersion process P1, the drying process P2, the 2nd immersion process P3, the roll end process P6 performed as needed, the vulcanization process P4, and the reverse removal process P5. Since the surgical glove 1 is manufactured, the surgical glove 1 excellent in economy and safety can be easily provided.

  In addition, since this method of manufacturing a surgical glove uses a ceramic hand mold 10, the outer surface of the ceramic as a material can be used as a fine rough surface 10a. A fine rough surface S suitable for one outer surface can be easily formed.

  Moreover, the surgical glove 1 manufactured by the manufacturing method which concerns on the said embodiment exhibits the following effects.

  Since palm part 2 is provided with 1st color rubber layer R1 laminated on the outer surface in addition to 2nd color rubber layer R2, it is excellent in economical efficiency and safety. That is, the palm part 2 is constituted by two layers of the second color rubber layer R2 on the inner surface side and the first color rubber layer R1 on the outer surface side by a so-called double dip manufacturing method by the first soaking process P1 and the second soaking process P3. Therefore, if damage (including pinholes) occurs on the surface (first color rubber layer R1) of the palm 2 during surgery, the second color rubber layer R2 is exposed to the first color rubber layer R1. . As a result, it is very easy to visually confirm that the surgical glove 1 has been damaged.

  And by this visual recognition, by replacing the damaged surgical gloves 1 with new ones, the number of surgical gloves 1 to be used can be reduced as compared with the case of replacing even if no damage has occurred. Can do. As a result, the surgical gloves 1 are not used wastefully and are extremely economical.

  Further, since the surgical glove 1 can easily visually recognize the damage generated in the palm part 2, it can be replaced with a new one at the same time as the damage occurs. Accordingly, it is possible to prevent a situation in which a damaged item is continuously used as it is, so that the safety is excellent.

  Furthermore, since the palm part 2 has a two-layer structure of the second color rubber layer R2 and the first color rubber layer R1, it has excellent mechanical strength. Pinholes and other damage are unlikely to occur during both operations. This also increases safety.

  Further, if the outer surface of the palm portion 2 is formed of the brown first color rubber layer R1, light reflection is less than that of white or the like. Therefore, it does not adversely affect the eyes of the worker due to the strong light reflection during the operation. In addition, it is possible to prevent blood adhering to the palm part 2 from flickering.

  In addition, since the surgical glove 1 is provided with the forearm portion 3, it is possible to reliably cover and protect the hem portion where the dirt is most worrisome in the surgical gown. Therefore, the hem portion of the surgical gown can be kept hygienic.

  Further, since the surgical glove 1 is formed with a fine rough surface S formed by a fine rough surface 10a existing on the outer surface of the hand mold 10 on the outer surfaces of the palm portion 2 and the forearm portion 3, this The fine rough surface S serves to prevent slipping. As a result, the surgical instrument can be stably held without sliding, and the safety of the operation can be ensured.

  Furthermore, the cuff part 4 is formed in the terminal part of the forearm part 3, and since this cuff part 4 is roll shape, it is rich in elasticity. Accordingly, it is possible to reliably hold the upper portion of the sleeve jersey of the surgical gown and prevent the sleeve jersey from falling off.

  In addition, although the hand mold | type 10 in this embodiment is a product made from ceramics, this invention is not limited to this, The thing formed with another material (for example, metal) can be used.
