实施该发明的最佳实施例
本发明的最佳实施方式
[0034] 为更进一步阐述本发明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, 对本发明的具体实施方式、 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发明, 并不用于限定 本发明。
[0035] 如图 1和图 2所示, 图 1是本发明气压式自动止血设备优选实施例的平面结构示 意图; 图 2是本发明气压式自动止血设备优选实施例的使用状态示意图。
[0036] 在本实施例中, 所述气压式自动止血设备 100包括止血带 1、 止气夹 2以及气压 控制装置 3。 所述止血带 1是一种呈无囊带状体结构的无囊止血带, 且由热塑性 聚氨酯弹性橡胶 (Thermoplastic 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。 所述止血带 1的内表面 11涂覆有防透气的硅胶层, 从而增加所述止血 带 1的气密封性, 以防止所述止血带 1老化导致充气后气体漏气。 在本实施例中 , 由于止血带 1内部没有设置专门用于充气的内置气囊, 使得止血带 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。
[0037] 所述止气夹 2通过滑槽 20可滑动地设置在所述止血带 1的任意一端位置处 (例如 止血带 1的左端或右端) , 该止气夹 2通过滑槽 20可沿所述止血带 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, 当所述止血带 1充气后, 所述止气夹 2可利用止血带 1内的充气弹力自动将贴在一起的止血带 1 两端夹紧, 以便使用者将止血带 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沿止血带 1上滑动, 因此可根据需要利用止气夹 2自由控制止 血带 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。
[0038] 在本实施例中, 所述止血带 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 端密封连通至所述气压控制装置 3上。 所述止血带 1的内表面设置有气压感测器 1 3, 该气压感测器 13通过信号线 14连接至所述气压控制装置 3上, 用于侦测止血 带 1内的气压值并发送至所述气压控制装置 3。
[0039] 所述气压控制装置 3上设置有进气孔 35和排气孔 36, 所述进气孔 35用于当利用 气压控制装置 3对止血带 1进行充气吋吸入外部空气。 所述排气孔 36用于当利用 气压控制装置 3对止血带 1进行放气吋排出止血带 1内的气体。 在本实施例中, 所 述气压控制装置 3可以通过进气孔 35自动吸入外部空气为止血带 1充气, 以及通 过排气孔 36自动排出止血带 1内的气体, 以便定吋调节止血带 1对伤口面的气压 大小, 从而防止因止血压力过大造成伤口面的肌肉组织坏死, 或者因止血压力 过小而造成止血效果不佳的问题。
[0040] 在本实施例中, 所述进气孔 35和排气孔 36可以设置在所述气压控制装置 3的任 意位置处, 例如, 气压控制装置 3的底部、 正面、 背面或者侧面任意位置处。 在 本实施例中, 所述进气孔 35和排气孔 36均设置在所述气压控制装置 3的底部。
[0041] 参考图 2所示, 在使用本发明所述气压式自动止血设备 100对人体手部、 脚部或 躯干部的伤口进行止血吋, 使用者首先将止血带 1的两端折叠在一起并将止气夹 2紧扣在止血带 1的两端从而使得所述止血带 1形成环状空腔 5, 并将手部或脚部 套入所述空腔 5内使将止血带的内壁紧贴伤口面。 然后, 使用者按下气压控制装 置 3上的电源幵关 31通过所述进气孔 35对止血带 1进行充气, 由于止血带 1内部的 气压升高促使止气夹 2紧扣在止血带 1的两端达到密封作用, 通过止血带 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, 当使用所述气压式自动止血设备 100对伤口面止血完毕后, 气压控制装 置 3控制排气孔 36排出止血带 1内的气体, 进而减少止血带 1的厚度与体积, 便于 使用者随身携带使用。

造成伤口面组织坏死的情况发生。
[0045] 所述电源幵关 31用于控制所述气压式自动止血设备 100的幵启或关闭, 所述显 示屏 32用于显示止血吋间和止血带 1内的气压值, 所述计吋器 33用于计算所述止 血带 1对伤口面的止血吋间。 所述微型气泵 34用于从进气孔 35吸入气体对止血带 1进行充气, 以及通过排气孔 36排出止血带 1内的气体。 在本实施例中, 所述进 气孔 35和排气孔 36均通过内置在所述气压控制装置 3的导气管连通至所述微型气 泵 34。 所述扬声器 37用于当所述止血吋间到达预设吋间吋播放语音信息通知医 护人员检査伤口的止血情况。 所述微型电池 38用于为所述气压控制装置 3提供工 作电源, 所述微型电池 38可以为可充电的锂电池或纽扣电池。
