手部保護手是人體器官中最為精細致密的器官之一。它由27塊骨骼組成,占人體骨骼總數的1/4,而且 肌肉、血管和神經的分布與組織都極其驚人的復雜,僅指尖上每平方厘米的毛細血管長度就可達數米,神經末梢達數千個。這些精細的神經網絡可以使我們在幾微秒內覺察到冷、熱、疼痛等,甚至可以感受到振幅只有頭發絲那么微小的震動。從人的出生之日起,手就沒有停止過活動,到生命終止時,手平均可以活動2.5億次。然而,我們卻常常忽略了手的重要性,疏忽了對它的適當保護,以致在各類喪失勞動能力的工傷事故中,手部傷害事故占到了20%。由此可見,正確選擇和使用防護用具十分必要。外傷性創傷這類手部傷害,是由于機械原因造成對骨骼、肌肉或組織、結構的傷害,從嚴重的斷指、骨裂到輕微的皮肉之傷等。如使用帶尖銳部件的工具,操縱某些帶刀、尖等的大型機械或儀器,會造成手的割傷等;處理、使用錠子、釘子、起子、鑿子、鋼絲等會刺傷手;手被卷進機械中會扭傷、壓傷甚至軋掉手指等。
Hand protection is one of the most delicate and compact organs in human organs. It consists of 27 bones, which accounts for 1/4 of the total number of bones, and the distribution and tissue of muscles, blood vessels and nerves are extremely complex. The length of each centimetre of capillary on the fingertips can reach several meters and thousands of nerve endings. These fine neural networks enable us to detect cold, heat, pain and so on in a few microseconds, and even feel that the amplitude of the vibration is only as small as the hair of the hair. From the day of birth, the hands did not stop activities, and when the end of life, the average hand can move 250 million times. However, we often ignore the importance of hand and neglect the proper protection of it, so that in all kinds of work injury accidents, hand injury accidents account for 20%. Therefore, it is very necessary to choose and use protective appliances correctly. Traumatic injuries such as hand injuries are caused by mechanical causes of injury to the bones, muscles, or tissue and structure, from severe finger, bone crack to slight skin injury. If a tool with sharp parts is used, a large machine or instrument with a knife and tip can be manipulated to cause a cut of a hand, such as a hand, a spindle, a nail, a chisel, a chisel, a wire and so on. The hand is sprained, pressed and even rolled out of the finger.
