在一些实施例中,推注组件220还包括丝杠套端盖227,丝杠套端盖227连接于丝杠套228背离驱动电机224的一端,丝杠套端盖227用于直接接触卡式瓶200的瓶塞204。
首先,丝杠套端盖227封堵丝杠套228的端部,可以避免外部杂物进入丝杠套228内,避免丝杠226与丝杠套228转动时受到杂物干扰,提升了推注组件220注射精度。其次,丝杠套端盖227可以防止水分或者电解
质溶液进入丝杠套228内,避免丝杠226以及丝杠套228出现锈蚀,提升了注射装置的使用寿命。再者,丝杠套端盖227朝向卡式瓶200的一端的摩擦系数较大,可以与卡式瓶200的瓶塞204稳定接触,可以确保瓶塞204稳定地在瓶身202内运动,提升了注射过程的稳定,可以精确控制药物注射量。

在提示组件180包括蜂鸣器182和显示屏184时,蜂鸣器182通过振动和声音提示用户注意药液的温度状态,显示屏184可以通过颜色、符号以及内容提示用户注意药液的温度状态。与此同时,显示屏184可以实时、
精确地显示剩余药液的剂量,注射前可以设定注射剂量,当设定注射剂量大于剩余剂量时,显示屏184会给出提示取消本次注射还是继续注射。如果选择继续注射,显示屏184还会提示有多少剂量未在本次注射,需要更换卡式瓶200以完成本次注射,确保注射剂量的正确性。更换卡式瓶200之后,显示屏184显示剩余剂量,方便后续的使用。此外,显示屏184还可以显示剩余电量,注射速度和状态等信息。

在本申请的实施例中,温度传感器140直接接触固定座124内的卡式瓶200,可以直接检测卡式瓶200以及药液的温度,而非环境温度,测量结果较为准确,可以避免药液疗效出现变化的情况。
需要说明的是,第一温度阈值小于第二温度阈值,第一温度阈值和第二温度阈值之间属于安全使用温度,小于第一温度阈值或者大于第二温度阈值属于不安全的使用温度。
在温度大于等于第一温度阈值且小于等于第二温度阈值时,药液温度符合要求,提示组件180提醒用户放心使用,可以开始注射工作。
在温度小于第一温度阈值或者大于第二温度阈值时,药液温度不符合要求,提示组件180提醒用户放弃注射,或者及时将药液放回冰箱冷藏。
在一些实施例中,固定座124为两端贯通的筒状结构,固定座124内形成有卡式瓶容纳腔,固定座124上形成有连通于卡式瓶容纳腔的通孔1242,温度传感器140具有弹性,可以使感应端在弹性作用下穿设于通孔1242。
温度传感器140的感应端抵接于固定座124内的卡式瓶200,可以直接检测卡式瓶200以及药液的温度。
在一些实施例中,推送出口102处可选择的设置有第一压力传感器,第一压力传感器电连接于控制器160。
主体100与药仓120稳定连接是注射工作开展的前提,关系到电路连
接以及注射精度等问题,注射药液前需要确保主体100和药仓120稳定连接,避免出现中途脱落或者断电的情况。在推送出口102处可选择的设置有第一压力传感器,第一压力传感器用于获取主体100和药仓120接触时的压力,控制器160接收到主体100与药仓120锁紧时的压力信息后,启动注射工作。
在一些实施例中,推注组件220背离推注出口102的一端设置有第二压力传感器225,第二压力传感器225安装在驱动电机224的尾部,即远离丝杠226的一端,且第二压力传感器225电连接于控制器160。
丝杠套228接触卡式瓶200的瓶塞204时,接触时产生的压力沿着丝杠套228、丝杠226以及驱动电机224传递至第二压力传感器225。瓶塞204挤压空气和药液时的阻力不同,通过区分挤压空气和药液时的不同阻力,可以将卡式瓶200内的空气排出。
需要说明的是,第二压力传感器225设置在驱动电机224以及主体100的内壁之间,驱动电机224可以相对于主体100的内壁前后滑动,第二压力传感器225可以获取丝杠套228与瓶塞204之间的推注压力。
在第一种情况下,驱动电机224固定连接于支架222,支架222可以相对于主体100的内壁滑动,进而传递丝杠套228与瓶塞204之间的推注压力。
在第二种情况下,驱动电机224滑动连接于支架222,支架222固定连接于主体100的内壁,驱动电机224可以传递丝杠套228与瓶塞204之间的推注压力。
在第三种情况下,驱动电机224滑动连接于支架222,第二压力传感器225连接于驱动电机224以及支架222,支架222可以为第二压力传感器225提供支撑,驱动电机224可以传递丝杠套228与瓶塞204之间的推注压力。
注射过程中,首先,丝杠套228快速前进寻找瓶塞204和自动排气,丝杠套228接触到瓶塞204时,速度便会下降,驱动电机224带动丝杠套228回旋两圈后退1.4mm,卸除瓶塞204和丝杠套228之间的接触压力,可以使瓶塞204恢复至自然形态,有利于排气工作的实现,可以防止过冲造成药液浪费,根据瓶塞204前进时的阻力信息可以判断是否排气完成;
其次,排气完成后,丝杠套228按照设定的速度前进,将药液注入人体内。
相关技术中,在非专业医护人员的操作下,注射装置可能在注射前过早的启动或者在注射过程中异常脱离患者,导致药液浪费,进而无法完成预期剂量的注射。同时,还可能存在推注组件220过早复位导致回血问题的发生。在一些实施例中,注射装置还包括第三压力传感器260,第三压力传感器260设置于药仓120对应于出液口128边缘的端面处,用于获取出液口128与皮肤之间的接触压力。
控制器160与第三压力传感器260电连接,控制器160可以根据接触压力控制推注组件220和提示组件180的运行。
第三压力传感器260安装在药仓120上,控制器160安装在主体100内,主体100与药仓120之间的电路是可拆卸连接的结构,例如通过Pogo pin连接器连接,主体100在推送出口102处设置有电极,电极连接于控制器160,药仓120在推送入口122处设置Pogo pin连接器,Pogo pin连接器电连接于第三压力传感器260。主体100和药仓120装载在一起后,在Pogo pin连接器的弹性作用下,第三压力传感器260电连接于控制器160。
根据本申请实施例提供的注射装置,注射装置工作时,通过第三压力传感器260获取出液口128和皮肤之间的初始接触压力;确定初始接触压力大于等于第一预设压力时,控制推注组件220处于电路导通状态且控制提示组件180发出第一提示信息,可以提醒用户放心使用;确定初始接触压力小于第一预设压力时,控制推注组件220处于电路切断状态且控制提示组件180发出第二提示信息,提醒用户将注射装置进一步紧贴皮肤,避免注射装置脱离皮肤,不会出现过早启动或者异常脱离皮肤的情况。避免出现药液浪费或者无法完成预期剂量的注射,给患者的财产和健康带来了保障。
在一些实施例中,第三压力传感器260为环状结构,且环状结构与出液口128同轴心设置,第三压力传感器260均匀分布于出液口128的周围,无论用户以任何角度握持注射装置,第三压力传感器260均可检测到出液口128和皮肤之间的接触压力,检测结果较为准确,避免出现无法接触皮肤的情况。
药仓120远离推送入口122的一侧形成有出液口128,固定座124朝向出液口128的一端形成有适于连接针头的外螺纹1244,药仓120与卡式瓶200以及针头的组装过程较为简单,安装效率较高。
卡式瓶200包括瓶身202和瓶塞204,瓶身202的尾部形成有开口,开口内插设有瓶塞204,瓶塞204用于将药液封堵在瓶身202内。
需要说明的是,瓶塞204为柔性结构,推注组件将瓶塞204推入瓶身202内时,可以将药液注入人体内。
在一些实施例中,主体100的侧壁形成有与手指相适配的握持部104,握持部104可以增加用户握持时的稳定性和舒适度。
在一些情况下,握持部104为形成于主体100的侧壁上的凹槽,凹槽的深度在5mm至6mm之间,数量可以为一个或者多个,且凹槽的尺寸与手指的尺寸相适配。用户握紧注射装置时,一根或者多根手指嵌入凹槽内,增加用户握持时的稳定性和舒适度。
在另一些情况下,握持部104为形成于主体100的侧壁上的凸起,凸起的数量为一个或者多个,且凸起与手指的指缝轮廓相适应。用户握紧注射装置时,一个或者多个凸起嵌入指缝内,增加了用户握持时的稳定性和舒适度。
根据本申请实施例提供的注射装置,控制器160包括主PCBA、滑动变阻器PCBA和Type C PCBA,滑动变阻器PCBA和Type C PCBA通过FPC软排线连接于主PCBA。主PCBA上连接有中央处理器、蜂鸣器以及电机连接端等部件,三个PCBA均连接于支架222。
主体100上形成有多个安装孔,用于安装Type C接口、电源键162、复位键以及注射键166等,用户通过显示屏184以及多个功能键与注射装置进行交互,可以实现注射过程的智能化控制,显示屏184也可以通过触摸控制。显示屏184通过显示屏支架安装在主PCBA上,显示屏护盖通过背胶粘贴在主体100上。
此外,Type C接口处插设有Type C盖168,可以防止主体100内进水,提升了注射装置的安全性。
电源键162设置在主体100的侧壁上,用户触压电源键162时,可以启动或者关闭注射装置。电源键162背离主体100的侧面相对于主体100
的侧壁内凹,例如凹陷1mm,电源键162没有延伸至主体100外。
将注射装置放置在桌面时,其他物体会受到主体100的侧壁的阻隔,不会误触电源键162。注射装置跌落时,电源键162不会接触地面,避免错误启动或者关闭注射装置。
根据本申请实施例提供的注射装置,药仓120与主体100为可拆卸的结构,药仓120和卡式瓶200安装在一起,可以将药仓120和卡式瓶200一起放在冰箱内进行冷藏,主体100内的电子元件不会受到冰箱内湿气的干扰。
在一些实施例中,固定座124朝向推送入口122的一端可拆卸连接有卡式瓶固定塞126,卡式瓶固定塞126适于限制卡式瓶200从固定座124内脱落。
卡式瓶200内的药液需要放置在冰箱内进行冷藏处理,以保证其药效。在使用时,将药仓120从冰箱内取出与外面的主体100装载在一起,可以进行药液的注射工作。为了防止卡式瓶200在取出或者装载时脱落,在固定座124上安装卡式瓶固定塞126。
在一些实施例中,卡式瓶固定塞126与固定座124之间设置有连接结构,将卡式瓶固定塞126从固定座124的端部拔出,卡式瓶固定塞126悬挂于固定座124的一侧,不会掉落。
根据本申请的实施例,药仓120背离推注入口122的一端形成有出液口128,固定座124朝向出液口128的一端安装有针头。
在一些实施例中,注射装置还包括隐针组件,隐针组件用于在注射前对针头进行遮挡,隐针组件包括隐针套筒240、滑动件242、弹性件244以及拨动件246。
隐针套筒240的外径与出液口128的内径相匹配,隐针套筒240滑动连接于出液口128,可以相对于药仓120伸出或者缩回。
滑动件242连接于药仓120的内壁,滑动件242的延伸方向与隐针套筒240的滑动方向相同。滑动件242的数量至少为一个,用于稳定隐针套筒240的运动过程。
在一些实施例中,滑动件242可以是形成于药仓120内壁的凹槽,隐针套筒240的外壁上形成有滑块,滑块与凹槽匹配连接。
在另一些实施例中,滑动件242包括导向筒,隐针套筒240连接于导向柱,导向柱活动插设在导向筒内。隐针套筒240相对于药仓120伸出或者收缩时,受到出液口128以及导向筒的限制,运动过程较为稳定。
药仓120和隐针套筒240之间还设置有弹性件244,弹性件244适于使隐针套筒240向远离药仓120的方向运动。在自然状态下,隐针套筒240相对于药仓120伸出,可以遮挡针头所在的位置。
药仓120的侧壁上形成有滑槽1201,拨动件246滑动连接于滑槽1201且传动连接于隐针套筒240。
需要说明的是,拨动件246在滑槽1201内的滑动方向与隐针套筒240的伸缩方向相同,用户可以通过拨动件246控制隐针套筒240的伸出以及缩回。
在滑动件242包括导向筒以及导向柱时,弹性件244为弹簧,弹簧设置在导向筒内且连接于导向柱。
拨动件246远离出液口128时,针头露出出液口128,露出的针头刺入患者的皮肤进行注射。拨动件246靠近出液口128时,隐针套筒240遮挡针头的位置,用户看不到针头,可以消除恐惧,还可以避免误伤皮肤。
需要说明的是,调节拨动件246的位置,可以更好地安装和拆卸针头,注射时不需要操作拨动件246。在正常情况下,弹性件244将隐针套筒240推向远离主体100的一端,以遮住针头消除注射恐惧。当注射完需要拆卸针头时,针头被隐针套筒240遮住,需要将拨动件246拉向靠近主体100的一侧,隐针套筒240后退,露出针头。便于使用者利用针帽将针头拆下。注射前同理,将拨动件246后拉,便于将针头安装在卡式瓶固定座上。注射时,隐针套筒240被皮肤压缩至与第三传感器260基本齐平,露出针头,针头刺入人体皮肤并完成注射。
在一些实施例中,固定座124上形成有第一观察窗1246,药仓120上形成有第二观察窗1202,第一观察窗1246与第二观察窗1202相对应。
在注射药液时,用户可以通过第一观察窗1246和第二观察窗1202直接看到卡式瓶200内药液的注射情况以及留存情况,使用时更加方便。第一观察窗1246和第二观察窗1202处可以设置玻璃或者塑料制作的透明窗体,减少了外部环境干扰,透明窗体上还可以设置刻度等标识信息,有助
于用户了解药液注射情况。
在一些实施例中,第一观察窗1246和第二观察窗1202的长度大于23mm,宽度大于8mm,透明窗体的透光率大于95%,表面硬度大于3H。
根据本申请的实施例,主体100可拆卸连接于药仓120,且推送出口102与推送入口122相对应。
在一些实施例中,推送出口102设置有连接件103,连接件103活动插接于推送入口122。
连接件103的外侧壁形成有相互连通的第一滑动槽1031和第二滑动槽1032,第一滑动槽1031与第二滑动槽1032之间具有夹角,且第一滑动槽1031延伸至连接件103的边缘位置。
药仓120的内壁形成有凸台121,凸台121与第一滑动槽1031和第二滑动槽1032相匹配。
为了提升连接件103与推送入口122连接的稳定性,第一滑动槽1031和第二滑动槽1032的数量可以为多组,凸台121的数量可以为多个。
在一些情况下,第一滑动槽1031和第二滑动槽1032的数量为两组,两组滑动槽之间的夹角为180°。
在另一些情况下,第一滑动槽1031和第二滑动槽1032的数量为三组,相邻滑动槽之间的夹角为120°。
在另一些情况下,第一滑动槽1031和第二滑动槽1032的数量为四组,相邻滑动槽之间的夹角为90°。
在主体100上装载药仓120时,将推送入口122与推送出口102相对应,凸台121先进入第一滑动槽1031,连接件103插入推送入口122。连接件103完全插入推送入口122内之后,转动药仓120或者主体100,两者之间发生相对转动,凸台121进入第二滑动槽1032内。
需要说明的是,第一滑动槽1031和第二滑动槽1032之间具有夹角,第二滑动槽1032会对凸台121形成限制作用,避免药仓120沿着主体100脱落,使用时更加稳定。
在一些实施例中,药仓120的内壁设置有板簧123,板簧123形成有弹性凸起1232,连接件103的外侧壁设置锁紧槽1033。
在装载药仓120时,对主体100和药仓120施加一定的作用力,凸台
121进入第一滑动槽1031内,然后再进入第二滑动槽1032内。在凸台121到达第二滑动槽1032的末端时,弹性凸起1232进入锁紧槽1033,弹性凸起1232和锁紧槽1033使主体100和药仓120进入锁紧状态,两者不会自动松开。用力转动药仓120和主体100,弹性凸起1232脱离锁紧槽1033,可以将主体100和药仓120拆开,主体100和药仓120之间的稳定性较高。
在推送出口102处设置有连接件103时,第一压力传感器用于获取凸台121在第二滑动槽1032的末端的压力信息,确保药仓120与主体100锁紧。
综上所述,根据本申请实施例提供的注射装置,包括主体100、药仓120、推注组件220和控制器160;主体100形成有推送出口102,推注组件220设置在主体100内,且对应于推送出口102设置,控制器160设置在主体100内,且与推注组件电路220连接,用以控制推注组件220的伸出以及缩回;药仓120形成有推送入口122,药仓120可拆卸连接于主体100,且推送入口122与推送出口102相对应,药仓120内设置有适于放置卡式瓶200的固定座124。推注组件220沿着推送出口102向推送入口122运动时,可以将卡式瓶200内的药液注入患者体内。药液注射完毕后,可以将药仓120和主体100分离,然后将药仓120以及药仓120内的卡式瓶200一起放入冰箱内冷藏。药仓120与主体100的拆装较为方便,方便了患者的使用,同时也不会对主体100内的电子元件造成损伤,有利于提升注射装置的使用寿命。
以上所述仅为本申请的较佳实施例而已,并不用以限制本申请,凡在本申请的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本申请的保护范围之内。
