Description

一种分体式多腔注射装置A split-type multi-chamber injection device

技术领域technical field

本发明涉及一种医疗器械,具体讲涉及一种分体式注射器。The invention relates to a medical device, in particular to a split injector.

背景技术Background technique

在现代化战争中,使用生化武器塔崩、沙林、梭曼等的可能性极大。一般的化学武器解毒药物多达三种以上,且需将几种混合使用。市售解毒剂注射产品目前多为单一药物或两种复方药物,而复方注射剂稳定性不够好,要完成解毒药的使用只能在注射完一种解毒剂后再注射另一种,高强度作战下如此注射操作不仅无法满足救治的需要,耽误了中毒伤员的最佳急救时间,还造成了中毒伤员的注射痛苦,在可能产生神经中毒症状的1-2分钟内无法完成全部操作,导致了中毒伤员死亡的可能性大大增加。因此,当发生化学武器战争时,需要一种1分钟内就能完成全部自救和互救操作的注射装置。为了与死神争夺生命,尽可能缩短救治时间的同时降低中毒人员的注射痛苦,并解决药物配伍的稳定性难题,北约、荷兰、美国等国家继相研制了多室注射器,以混合阿托品、双复磷、安定等救治药剂,更有英国、比利时、卢森堡等国研制了装入粉针的注射剂型,但是这些多腔室针筒腔室太少、针筒构造复杂,使用过程繁复,尚不足以在战争这个特殊场合中使用。In modern warfare, the possibility of using biological and chemical weapons such as Tabun, Sarin, and Soman is extremely high. Generally, there are as many as three or more antidotes for chemical weapons, and several of them need to be used in combination. Most of the antidote injection products on the market are a single drug or two compound drugs, but the stability of the compound injection is not good enough. To complete the use of antidote, you can only inject another antidote after injecting one antidote, high-intensity combat Such an injection operation not only fails to meet the needs of treatment, delays the best first aid time for the poisoned wounded, but also causes the injection pain of the poisoned wounded, and cannot complete all operations within 1-2 minutes when neurotoxic symptoms may occur, resulting in poisoning The probability of death of the wounded is greatly increased. Therefore, when a chemical weapons war takes place, an injection device that can complete all self-rescue and mutual rescue operations within 1 minute is needed. In order to compete with death for life, shorten the treatment time as much as possible, reduce the injection pain of poisoned personnel, and solve the problem of drug compatibility stability, NATO, the Netherlands, the United States and other countries have successively developed multi-chamber syringes to mix atropine, double compound injections, etc. Phosphorus, diazepam and other treatment agents, and the United Kingdom, Belgium, Luxembourg and other countries have developed injections filled with powder injections, but these multi-chamber syringes have too few chambers, complex syringe structures, and complicated use processes, which are not enough. Used on special occasions of war.

已有的200920000074.X和200820136184.4号专利介绍了两种多腔室注射器,他们的共同点在于需在器械制备的同时将药液预混灌装入注射器并密封,但目前预混装装置较少,现有器械生产厂家仅能生产器械无法灌装药品,而药品生产厂家又无法生产器械,因此无法实现器械、药品的整体预混灌装。The existing patents No. 200920000074.X and No. 200820136184.4 introduce two kinds of multi-chamber syringes. What they have in common is that the premixed liquid medicine needs to be filled into the syringe and sealed while the device is being prepared. However, there are few premixed devices at present. , Existing device manufacturers can only produce devices but cannot fill drugs, and drug manufacturers cannot produce devices, so it is impossible to realize the overall premixed filling of devices and drugs.

已公开的专利201210131616.3介绍的一种改进的多腔注射器虽然在一定程度上改进了以上两个专利的弊端,但是当所需药液量较少的情况下,其底部的中空刺破装置因体积较大残留药液量多,浪费了药液;同时,其刺破装置固定性不佳而导致储存时在外力下引起药剂刺破,达不到理想的储存状态。Although an improved multi-chamber syringe introduced in the published patent 201210131616.3 has improved the disadvantages of the above two patents to a certain extent, when the amount of liquid medicine required is small, the hollow piercing device at the bottom of the syringe will be affected by the volume. The large amount of residual liquid medicine is large, which wastes the liquid medicine; meanwhile, the poor fixation of the piercing device causes the medicine to puncture under external force during storage, and the ideal storage state cannot be reached.
