Bite, Sting & Tick Aid叮咬蜇伤与蜱虫处置
Snakebite do/don’t, tick removal with a Lyme watch timer, jellyfish, spiders and bee stings. 蛇咬该做/不该做、蜱虫移除与莱姆观察倒计时，还有水母、蜘蛛与蜂蜇。
Field protocols behind this bite and sting tool
Venom and bites punish improvisation. Almost every harmful folk remedy — cutting a snakebite, burning a tick, pouring freshwater over jellyfish tentacles — actively makes the injury worse. Each tab here follows a single principle: slow what the venom or infection is doing, document time, and evacuate calmly.
Snakebite
Current poison-center guidance is pressure/immobilization by stillness rather than constriction. Move everyone at least three metres from the snake, remove rings and watches before swelling starts, splint the bitten limb at or slightly below heart level, and keep the victim lying down. Record the bite time because progression of symptoms guides treatment, and note the snake’s colour, pattern and head shape — or photograph it from distance. Do not wash the wound vigorously, because hospitals may swab venom residues to identify the species. Do not catch or kill the snake: even a severed head can bite reflexively for hours. In the US call Poison Control at 1-800-222-1222; Australia uses 13 11 26; the UK uses NHS 111 or 999 in an emergency; the EU uses 112; mainland China uses 120.
Ticks and the 36–48 hour window
Borrelia bacteria that cause Lyme disease generally need 36–48 hours of attachment before transmission, which is why prompt mechanical removal matters: fine-tip tweezers at the skin line, straight upward pull, no twist, squeeze, heat or oil. Save the tick, mark the date, and use the built-in timer to track every recorded bite across page reloads. Most infectious ticks are poppy-seed nymphs, so do a full-body check, shower within two hours and tumble clothes on high heat for ten minutes. An expanding bullseye rash, fever or flu-like illness within days to weeks means a medical visit — not self-prescribed antibiotics.
Bees, spiders and jellyfish
For bee stings scrape the stinger out sideways in the first seconds; systemic signs (throat tightness, wheeze, hives beyond the site, facial swelling) mean epinephrine in the outer thigh, EMS, and lying flat with legs raised. Spider and scorpion care is mostly wash, cool compress, tetanus check and monitoring, with specific evacuation triggers for black widow cramps, recluse ulcers and bark scorpion stings in children. Jellyfish stings need vinegar for at least 30 seconds before tentacle removal and hot-water immersion at 40–45 °C — freshwater, urine, alcohol and ice all discharge more stinging cells.
本工具背后的野外处置原则
毒液与叮咬最怕“土办法”。几乎所有有害的民间做法——切开蛇咬伤口、火烧蜱虫、用淡水冲水母触手——都会让伤情更糟。每个标签页都遵循同一原则：减慢毒液或感染的进展、记录时间、冷静后送。
蛇咬
现行毒物中心指南强调“靠静止实现制动”，而不是勒扎。全队后撤至少 3 米，在肿胀开始前摘掉戒指手表，把伤肢固定在心脏水平或略低处，让伤者躺下。记录被咬时间（症状进展决定治疗），记住蛇的颜色、花纹与头形，或在远处拍照。不要用力擦洗伤口——医院可能用残留毒液拭子鉴别蛇种；不要捕蛇或打蛇，被砍下的蛇头数小时内仍会反射性咬人。美国毒物中心 1-800-222-1222，澳大利亚 13 11 26，英国 NHS 111（急救 999），欧盟 112，中国大陆 120。
蜱虫与 36–48 小时窗口
导致莱姆病的伯氏疏螺旋体通常需要蜱虫附着 36–48 小时才会传播，因此及时的机械移除很关键：细尖镊子贴近皮肤、垂直向上稳定拔出，不扭、不挤、不烫、不涂油。保存蜱虫、标记日期，用内置计时器记录每次叮咬（刷新页面仍保留）。多数传播莱姆病的是罂粟籽大小的幼蜱，因此要全身检查、2 小时内洗澡、衣物高温烘干 10 分钟。数天到数周内出现扩大的牛眼红圈皮疹、发热或流感样症状应就医，不要自行服用抗菌药。
蜂、蜘蛛与水母
蜂蜇要在最初几秒侧向刮掉毒刺；出现全身征象（喉咙发紧、喘鸣、蜇伤处以外起风团、面部肿胀）时，立即大腿外侧注射肾上腺素、拨打急救电话、平躺并抬高双腿。蜘蛛与蝎子以冲洗、隔布冷敷、查破伤风、密切观察为主，但黑寡妇导致的肌肉痉挛、棕色遁蛛造成的溃疡、以及儿童被树皮蝎蜇伤都需要后送。水母蜇伤先浇醋至少 30 秒再清触手，随后 40–45 °C 热水浸泡——淡水、尿液、酒精和冰都会触发更多刺细胞。
