Description

一种回缩收纳式注射器用针管装置 A recoil syringe with a needle accommodating means

技术领域 FIELD

[0001] 本发明涉及一种针管装置,尤其涉及一种回缩收纳式注射器用针管装置。 [0001] The present invention relates to a syringe device, particularly to a retractable syringe with a needle is retracted.

背景技术 Background technique

[0002] 近年来,公众(例如,医务人员和医疗保健提供商、吸毒成瘾者、吸毒者、和类似)已日益意识针头重复使用和意外扎伤事件针的健康危害问题。 [0002] In recent years, the public (for example, medical personnel and health care providers, drug addicts, drug addicts, and the like) have become increasingly conscious of the needle reuse and accidental health hazards of needle pricks event. 例如,至少二十种血源性疾病可以通过针头重复使用或意外扎伤事件而传播的。 For example, at least twenty blood-borne diseases can reuse or accidental needle stick injury by events and communication. 例如,这些血源性疾病可能包括、并不限于人类免疫缺陷病毒(HIV)、获得性免疫缺陷综合征(艾滋病)、乙型肝炎、丙型肝炎、梅毒、疟疾、结核病、和疱疹。 For example, these may include blood-borne diseases, is not limited to human immunodeficiency virus (HIV), acquired immunodeficiency syndrome (AIDS), hepatitis B, hepatitis C, syphilis, malaria, tuberculosis, and herpes. 在美国,针头的重复使用和针头意外扎伤事件已造成至少36%的艾滋病毒或艾滋病病例和50%以上的乙型肝炎和丙型肝炎的风险。 In the United States, needle reuse and accidental needle stick injuries has killed at least 36% of the risk of HIV or AIDS cases and more than 50% of hepatitis B and hepatitis C. 因此,有必要遏制共用针头吸毒者的做法。 Therefore, it is necessary to curb the practice of sharing needles addicts.

[0003] 查看关于世界人口时,进一步发现共用针筒或针头重复使用的严重问题。 [0003] view on world population, further found serious problems sharing syringes or needles reused. 大约有30%的艾滋病毒或艾滋病病例,例如在巴西、智利、乌拉圭、巴拉圭和阿根廷是直接使用受污染的针头。 About 30 percent of HIV or AIDS cases, such as in Brazil, Chile, Uruguay, Paraguay and Argentina are the direct use of contaminated needles. 在中国约70%的爱滋病病毒感染个案直接使用了受污染的针头。 In China about 70% of HIV infection cases directly using contaminated needles. 在东欧国家,80%的注射吸毒者承认有共享受污染的针头。 In Eastern European countries, 80% of injecting drug users were admitted to enjoy contaminated needles. 在波兰和南斯拉夫约43%的艾滋病毒或艾滋病病例都直接由于吸毒而造成针筒共享。 In Poland and Yugoslavia about 43 per cent of HIV or AIDS cases are caused directly by drug addicts sharing syringes.

[0004] 针头意外扎伤还威胁着医护人员。 [0004] accidental needle-stick injuries also threaten the health care provider. 尤其是,每年报道大约100万的意外扎伤由医护人员。 In particular, it reports about a million accidents annually stabbed by health care professionals. 不过相信非报道数据至少有300万起的意外针头扎伤每年发生,其中约200万个未报道。 But I believe there are non-reported data from at least three million accidental needle-stick injuries occur each year, of which about two million unreported. 各项研究估计,从所有意外针头扎伤到护士,发生没有报案的伤害的大约40%到53%。 Various studies estimate that from all accidental needle stick injuries to the nurse, did not report the occurrence of injuries is about 40% to 53%. 各项研究还估计,从所有的针头到实验室技术员,没有报案的伤害的大约92%。 The study also estimated that from all the needles to laboratory technicians, approximately 92% did not report injuries. 进一步的各项研究估计从针头到医生发生的伤害,报案的大约有70%到95%。 Further the study estimates the damage from the needle to the doctor occurs, a report of about 70% to 95%.

[0005] 1997年,美国疾病控制和预防中心(⑶C)的一项研究发现通过使用安全针头可以避免大约76%被针头扎伤。 [0005] In 1997, a study by the US Centers for Disease Control and Prevention (⑶C) found that by using a safety needle to avoid about 76% of needle-stick injuries. 目前,有多种类型的安全注射器。 Currently, there are many types of safety syringes. 不幸的是,目前这些市场上存在的安全注射器由于他们在众多的问题上,不仅是在使用中,而且是在有效性上一直被业界批评。 Unfortunately, existing on the market because of their safety syringe on many issues, not only in use, but has been criticized on the effectiveness of the industry. 因此还存在着巨大的改善空间。 Therefore, there is still huge room for improvement.

[0006] 一种类型的安全注射器是注射器的一个真空辅助的安全注射器。 [0006] One type of safety syringe is a syringe vacuum assisted safety syringe. 当阀门启动针罩时,由于真空室所产生的回缩力的原因,注射器的针头回缩进入针体内,当阀门从回缩位置到卡住位置时,真空室的回缩力是和阀门的表面呈比例的,如果真空室是不足够大的,那么真空室所产生的回缩力就不足够大,以至于无法将针头回缩到针管内,这个现象尤其是当液体室是具有一个小体积,如Icc以下,这个现象尤其严重,小的流体室要求针管有一个小的直径。 When the valve needle shield starts, due retractive force generated by the vacuum chamber, the syringe needle into the needle retraction body when the valve from the retracted position to the stopping position, the retraction force is the vacuum chamber and valves proportional to the surface of the vacuum chamber if it is not large enough, then the retractive force generated by the vacuum chamber is not sufficiently large that they can not retract the needle into the syringe, especially when this phenomenon is a liquid chamber having a small volume, such as less Icc, this phenomenon is particularly serious, small fluid chambers in claim needle cannula has a small diameter. 因此所对应的小的回缩力。 Thus the corresponding low retractive force. 小的回缩力阻碍着针头可回缩式的发展和使用潜力。 Small needle retraction force hindering the retractable development and use potential.

[0007] 同时,为了确保针头在使用过程中不会出现意外脱落,拥有良好的密封性能,需要提供特殊的针管装置。 [0007] Meanwhile, in order to ensure that the needle does not occur in the course of accidental loosening, it has a good sealing performance, it is necessary to provide a special needle device.
