Abstract

一种气压式无囊止血带，包括无囊包扎带（1）、止气夹（2）以及打气囊（3），所述无囊包扎带（1）呈无囊带状体结构，所述止气夹（2）通过滑槽（20）设置在所述无囊包扎带（1）的任意一端位置处，所述无囊包扎带（1）的外表面设置有进气阀（10），该进气阀（10）连接有进气管（4），所述进气管（4）的一端密封连通至所述进气阀（10）上，所述进气管（4）的另一端密封连通至所述打气囊（3）上。由于无囊包扎带（1）内没有设置专门用于充气的内置气囊，使得无囊包扎带（1）充气后与皮肤止血面接触不会产生褶皱，增强了止血效果，且更易于弯折，便于使用者携带。此外，利用弹压式止气夹（2）可在无囊包扎带（1）充气时自动夹紧所需充气部位，减少充气时间而满足快速止血的需求。

Description

说明书 发明名称：气压式无囊止血带
技术领域
[0001] 本实用新型涉及生命紧急救护领域， 尤其涉及一种气压式无囊止血带。
背景技术
[0002] 止血带是用于四肢大出血急救吋简单、 有效的止血装置， 它通过压迫血管阻断 血液流动来达到止血目的， 止血带广泛应用于普外科四肢动静脉创伤止血或外 科四肢手术止血， 目前市面上常见的无囊包扎带主要有橡皮管止血带、 卡扣式 止血带及充气止血带。 目前出现有的充气止血带均为有囊止血带， 它是由带有 内部气囊的止血带组成， 虽然可以止血， 但是由于气囊包裹在止血带内使得止 血带整体较厚， 且在使用吋需要为止血带的气囊整体充气， 因此充气吋间较长 而不方便快速止血的需求。 此外， 由于气囊包裹在止血带内使得止血带与皮肤 止血面接触易产生褶皱， 且内部气囊长吋间折叠易老化而导致漏气， 因此导致 止血效果不好等诸多问题。

[0012] 图 1是本实用新型气压式无囊止血带优选实施例的平面结构示意图；
[0013] 图 2是本实用新型气压式无囊止血带优选实施例的使用状态示意图。
[0014] 本实用新型目的实现、 功能特点及优点将结合实施例， 参照附图做进一步说明 实施该发明的最佳实施例
本发明的最佳实施方式
[0015] 为更进一步阐述本实用新型为达成上述目的所采取的技术手段及功效， 以下结 合附图及较佳实施例， 对本实用新型的具体实施方式、 结构、 特征及其功效进 行详细说明。 应当理解， 此处所描述的具体实施例仅仅用以解释本实用新型， 并不用于限定本实用新型。
[0016] 如图 1和图 2所示， 图 1是本实用新型气压式无囊止血带优选实施例的平面结构 示意图； 图 2是本实用新型气压式无囊止血带优选实施例的使用状态示意图。 [0017] 在本实施例中， 所述气压式无囊止血带包括无囊包扎带 1、 止气夹 2以及打气囊 3。 所述无囊包扎带 1呈无囊带状体结构， 且由热塑性聚氨酯弹性橡胶 (Thermopla stic polyurethanes , TPU)制成， 所述 TPU具有耐磨、 耐油、 弹性好等特性， 在日 用品、 体育用品、 玩具用品、 医疗用品等领域得到广泛应用。 所述无囊包扎带 1 的内表面 11涂覆有防透气的硅胶层， 从而增加所述无囊包扎带 1的气密封性， 以 防止所述无囊包扎带 1老化导致充气后气体漏气。 在本实施例中， 由于无囊包扎 带 1内部没有设置专门用于充气的内置气囊， 使得无囊包扎带 1充气后与皮肤止 血面接触不会产生褶皱， 从而增强了止血效果， 且更易于弯折， 便于使用者携 带。
[0018] 所述止气夹 2通过滑槽 20可滑动地设置在所述无囊包扎带 1的任意一端位置处 ( 例如无囊包扎带 1的左端或右端） ， 该止气夹 2通过滑槽 20可沿所述无囊包扎带 1 的左右端滑动。 在本实施例中， 所述止气夹 2为一种带有滑槽 20的弹压式装置， 当所述无囊包扎带 1充气后， 所述止气夹 2可利用无囊包扎带 1内的充气弹力自动 将贴在一起的无囊包扎带 1两端夹紧， 以便使用者将无囊包扎带 1固定在所需止 血的伤口部位进行止血。 由于止气夹 2可通过滑槽 20沿无囊包扎带 1上滑动， 因 此可根据需要利用止气夹 2自由控制无囊包扎带 1的充气区域大小， 从而减少充 气吋间满足快速止血的需求。
[0019] 在本实施例中， 所述无囊包扎带 1的外表面 12设置有进气阀 10， 该进气阀 10连 接有进气管 4。 所述进气管 4的一端密封连通至所述进气阀 10上， 所述进气管 4的 另一端密封连通至打气囊 3上， 使用者可以通过手捏所述打气囊 3对无囊包扎带 1 进行充气。 所述打气囊 3为一种呈椭圆形或圆形的橡胶囊体。
[0020] 所述打气囊 3与进气管 4的连接处设置有排气阀 40， 该排气阀 40用于排出所述无 囊包扎带 1内的气体。 当使用者通过手捏所述打气囊 3对无囊包扎带 1进行充气吋 ， 该排气阀 40处于关闭状态。 当所述无囊包扎带 1内的气体需要排出吋， 使用者 可以手动打幵排气阀 40排出所述无囊包扎带 1内的气体， 以便调节无囊包扎带 1 对伤口面的气压力大小， 防止压力过大容易造成肌肉组织坏死， 对伤口面造成 一定的二次损伤， 因此需要定吋对充气的无囊包扎带 1进行放气而防止伤口面的 肌肉组织坏死。 [0021] 所述打气囊 3上设置有进气孔 30， 该进气孔 30用于使用者利用打气囊 3对无囊包 扎带 1进行充气吋吸入外部空气。 所述进气孔 30可以设置在所述打气囊 3的任一 位置处， 在本实施例中， 所述进气孔 30设置在所述打气囊 3的底部， 便于使用者 用手拿捏打气囊 3对无囊包扎带 1进行充气。
[0022] 参考图 2所示， 在使用本实用新型所述气压式无囊止血带对人体手部、 脚部或 躯干部的伤口进行止血吋， 使用者首先将无囊包扎带 1的两端折叠在一起并将止 气夹 2紧扣在无囊包扎带 1的两端从而使得所述无囊包扎带 1形成环状空腔 5， 并 将手部或脚部套入所述空腔 5内使将无囊包扎带的内壁紧贴伤口面。 然后， 使用 者通过手捏打气囊 3对无囊包扎带 1进行充气， 由于无囊包扎带 1内部的气压升高 促使止气夹 2紧扣在无囊包扎带 1的两端达到密封作用， 通过无囊包扎带 1不断充 气升压来达到压迫伤口血管来阻断血管流血， 从而实现对人体伤口止血的效果 。 此外， 当使用所述气压式无囊止血带对伤口面止血完毕后， 使用者可以手动 打幵排气阀 40排出无囊包扎带 1内的气体， 进而减少所述无囊包扎带 1的厚度与 体积， 便于使用者随身携带使用。
[0023] 以上仅为本实用新型的优选实施例， 并非因此限制本实用新型的专利范围， 凡 是利用本实用新型说明书及附图内容所作的等效结构或等效功能变换， 或直接 或间接运用在其他相关的技术领域， 均同理包括在本实用新型的专利保护范围 内。
工业实用性
[0024] 相较于现有技术， 本实用新型所述气压式无囊止血带采用上述技术方案， 达到 了如下技术效果： 采用无囊包扎带在充气后与皮肤止血面接触不会产生褶皱， 从而增强了止血效果； 由于无囊包扎带内没有设置专门的充气囊， 从而减少了 止血带的厚度与体积， 且更易于弯折； 利用弹压式止气夹对无囊包扎带充气吋 自动夹紧所需充气部位， 因此使用者可根据需要自由控制充气区域大小， 从而 减少充气吋间满足快速止血的需求。
