Description
Translated fromChinese本发明涉及喂药技术领域，特别涉及一种喂药器。The invention relates to the technical field of medicine feeding, in particular to a medicine feeder.
众所周知，对婴幼儿喂药费时费力，操作难度大。尤其是较苦的药液，婴幼儿格外的抗拒和排斥。As we all know, feeding medicine to infants and young children is time-consuming and labor-intensive, and the operation is difficult. Especially the more bitter liquid medicine, infants and young children are particularly resistant and repelled.
使用现有的喂药器进行喂药时，一般都是先将药液通过喂药器注入至婴幼儿的口中，然后再更换另外一个喂药器将事先装好的糖水注入至婴幼儿的口中，通过糖水漱口来缓和药液的苦味，并安抚小孩的情绪。或者采用同一个喂药器再次吸入糖水，并注入至小孩的口中。如此一来，注入药液和糖水之间一方面存在时间差，变相延长了小孩的痛苦感，另外一方面，喂药器需要再次塞入至小孩的口中。小孩由于条件反射和口中苦味感，会持续紧闭嘴巴，可能还会伴随哭闹的抗拒情绪，进而导致第二次喂药或者喂糖水难以实施，给喂药带来了极大的不便。When using the existing medicine feeder to feed medicine, generally the medicine liquid is injected into the mouth of the infant through the medicine feeder, and then another medicine feeder is replaced to inject the pre-filled sugar water into the mouth of the infant and child. , gargle with sugar water to ease the bitter taste of the liquid medicine and soothe the child's mood. Or use the same applicator to inhale the sugar water again and inject it into the child's mouth. As a result, on the one hand, there is a time difference between the injection of the medicinal liquid and the sugar water, which in disguise prolongs the child's pain, and on the other hand, the medicine feeder needs to be inserted into the child's mouth again. Due to conditioned reflexes and a bitter taste in the mouth, children will keep their mouths tightly closed, and may also be accompanied by crying resistance, which makes it difficult to implement the second feeding or feeding of sugar water, which brings great inconvenience to feeding.
发明内容SUMMARY OF THE INVENTION

其中，第一管体100的前端部具有注射端头120，第一管体100的后端部形成有第一腔体130，注射端头120内部形成注射通道121，注射通道121贯穿第一腔体130的侧壁后与 第一腔体130连通。第二管体200的前端部安装有第一活塞400，第二管体200通过第一活塞400活动密封安装在第一腔体130的内侧壁上，第二管体200的后端部形成有第二腔体220，第一活塞400内部形成有液体流道410，液体流道410的一端与第二腔体220连通，另一端具有连通和密闭两种状态，第一活塞400远离第一管体100的前端部滑动时，液体流道410的另一端保持密闭，第一活塞400滑动至与第一管体100的前端部内侧抵接时，液体流道410的另一端切换成与注射通道121连通。拉杆300的一端安装有第二活塞500，拉杆300通过第二活塞500活动密封安装于第二腔体220内。拉杆300的另一端设置有第三把持凸起310，第三把持凸起310上设置有拉环320，方便操作。The front end of the
使用该喂药器装入药液和糖水之前，先将喂药器设置为初始状态，即第一活塞400滑动至与第一管体100的前端部内侧抵接，第二活塞500滑动至与第二管体200的前端部内侧抵接。按住第二管体200，拉动拉杆300，使得第二活塞500远离第二管体200的前端部滑动，糖水经过注射通道121、处于连通状态的液体流道410进入至第二腔体220内，进而完成糖水的预装。之后拉动第二管体200，使得第一活塞400远离第一管体100的前端部滑动，此时，液体流道410切换为密闭状态，第二腔体220内的糖水保持密封状态，药水经过注射通道121进入至第一腔体130内，进而完成药水的预装。喂药时，使用者下压拉杆300，由于第二腔体220保持密封状态，第一腔体130内的药水先经过注射通道121注入至小孩的口中，当第一活塞400滑动至与第一管体100的前端部内侧抵接时，药水注入完毕。与此同时，液体流道410切换成与注射通道121连通，此时糖水可以无缝衔接的继续注入至小孩的口中。使用该喂药器可以一次性预装药水和糖水，并能够实现先向小孩口中注入药水，再注入糖水的连贯动作。注入药水后与注入糖水之前不存在时间间隙。一方面尽可能的减少了小孩的痛苦感；另一方面，避免了分开两次去执行，解决了小孩因抗拒情绪而紧闭嘴巴的问题。Before using the medicine feeder to load the liquid medicine and sugar water, set the medicine feeder to the initial state, that is, the
优选地，注射通道121设置在第一管体100的前端部的外周部，注射通道121在靠近第一腔体130的端口朝向第一管体100的中心轴设置。如此一来，可以很高效的借助第一活塞400的滑动来实现液体流道410与注射通道121连通情况的快速切换。Preferably, the
一些实施例中，第一活塞400的外周设置有环形凹槽420，第一活塞400滑动至与第一管体100的前端部内侧抵接时，环形凹槽420与注射通道121连通。环形凹槽420的两侧部与第一管体100的内侧壁活动密封连接，通过设置环形凹槽420，便于装配，解除对第一活 塞400的定向安装，即第一活塞400随意安装都可以确保当第一活塞400滑动至与第一管体100的前端部内侧抵接时注射通道121可以通过环形凹槽420与液体流道410连通。In some embodiments, the outer circumference of the
优选地，第一管体100的后端部形成有第一把持凸起110，第二管体200的后端部形成有第二把持凸起210，第一把持凸起110与第二把持凸起210交错布设，交错布设的第一把持凸起110与第二把持凸起210在靠近的时候不会相互干涉，解决了因紧邻而导致操作不便的问题。Preferably, a
或者，第二把持凸起210的外轮廓尺寸大于第一把持凸起110的外轮廓尺寸。如此一来，在进行药水的预装时，使用者可以一只手握住第一管体100，另外一只手握持第二把持凸起210，上拉第二管体200以完成药水的预装。Alternatively, the outer contour size of the
需要理解是，糖水预装时只要按住第一把持凸起110和第二把持凸起210，再拉后面拉杆300，就可实现。It should be understood that, when the sugar syrup is pre-installed, it is only necessary to hold down the
需要理解的是，由于该喂药器为嵌套式结构，先预装糖水，再预装药水，能够避免药水与糖水混合。It should be understood that, since the medicine feeder is a nested structure, the syrup is pre-filled first, and then the syrup is pre-loaded, which can prevent the syrup from mixing with the syrup.
优选地，第二管体200与第一活塞400可拆卸连接，拉杆300与第二活塞500可拆卸连接，以便于拆卸与清洗。Preferably, the
一些实施例中，第二管体200的前端部形成有插入至液体流道410的中空插头230，中空插头230连通液体流道410和第二腔体220。In some embodiments, the front end of the
优选地，第一管体100和第二管体200的外周设置有刻度线，以便于控制注入量。Preferably, the outer circumferences of the
