技术领域technical field
本发明涉及皮肤科医疗工具技术领域，特别是一种防污染皮肤涂药装置。The invention relates to the technical field of dermatological medical tools, in particular to an anti-pollution skin drug applicator.
背景技术Background technique
在皮肤疾病治疗过程中，外用药物疗法可以直接将药物施加于患者的病灶处，因而其治疗效果非常显著，是皮肤病治疗的主要手段；但是，由于多数外用药物一般为软管包装的膏状或液体，使用时需要从包装中挤出而进行涂抹，因此，在涂抹过程中，当药物出口与操作人员的手指或直接与患者的病灶部位接触后，会使药物及药物包装的出药口受到二次污染，后期再次使用时极易与其他患者产生交叉感染，不利于疾病的治疗与彻底康复。In the process of skin disease treatment, external drug therapy can directly apply the drug to the patient's lesion, so its therapeutic effect is very significant, and it is the main means of skin disease treatment; or liquid, it needs to be squeezed out from the package for smearing during use. Therefore, during the smearing process, when the drug outlet comes into contact with the operator's fingers or directly with the patient's lesion, the drug and the drug outlet of the drug package will Due to secondary pollution, it is very easy to cause cross-infection with other patients when it is used again later, which is not conducive to the treatment and complete recovery of the disease.
同时，由于该类药物的用量视病情而定，一般情况下药物不会一次性用完，剩余的药物需要密封保存以备后用；而在保存过程中，一方面存在着上述二次污染问题，另一方面，药物存放后可能会因各种外部因素如重压、温度等影响使药物被挤出，造成医疗资源的严重浪费。At the same time, since the dosage of this type of medicine depends on the condition, generally the medicine will not be used up at one time, and the remaining medicine needs to be sealed and stored for later use; and during the preservation process, on the one hand, there is the above-mentioned secondary pollution problem , On the other hand, after the drug is stored, it may be squeezed out due to various external factors such as heavy pressure, temperature, etc., resulting in a serious waste of medical resources.
此外，由于药膏涂抹治疗具有极大的便利性，因此一般的皮肤疾病不需住院治疗，患者可以按照医嘱自行涂抹；但不同于专业医疗环境，家庭使用时药物的保存较为随意，任何人都可能会与药物产生接触，容易造成疾病传染；另外，通常情况下外用药物是严禁用于口服的，一旦有人因误食而将药物吞服，将会带来难以预料的安全事故。In addition, due to the great convenience of ointment application treatment, general skin diseases do not require hospitalization, and patients can apply it on their own according to the doctor's advice; There will be contact with drugs, which will easily cause disease transmission; in addition, it is strictly forbidden to take drugs for external use orally. Once someone swallows the drugs by mistake, it will cause unpredictable safety accidents.
综上所述，现有的外用药使用方式不仅易使患者、医护人员及家属之间产生疾病传播与交叉感染，还存在着易被吞食的危险，具有较大的医疗安全隐患。To sum up, the existing external use methods not only easily cause disease transmission and cross-infection among patients, medical staff and family members, but also have the risk of being easily swallowed, which poses a greater medical safety hazard.
