Abstract
The invention provides an improved control device for an intravenous dripping system based on the gravity infusion principle. The device has an air-bag which connects to a ventilating needle via a catheter with the needle inserted into a drug bottle. When the drug bottle is about to be empty, the air-bag has already been emptied so that no air goes into the drug bottle, thereby preventing the drug in the drug bottle from dripping and preventing air entrance into the needle. Furthermore, the air bag can be filled with fresh air so that contaminated air can be avoided to get into the drug bottle.

现代医学的发达及药物的进展，治疗患者一住院即施于点滴并加入各种药物在点 滴药内，形成各住院部几乎全部在吊点滴。然而 500 C. C.药水点滴下来约需 4小时左 右时间，特别点滴快滴完前均需察看二、三次才能处理。 观察每住院部一区的病床数 均一百多床，照料的护理人员约四、五位，可想而知，光察看点滴状况就使护理者工 作负载过重，自然形成护理者更换工作造成今日的护士荒问题。 请参阅图 1,目前点 滴瓶于注射时的结构 10为药水瓶 11、透气针 12、导药针 13、点漓筒 14及一导管 15所构 成，将该导管 15连接至注射针头上，再将注射针头插入患者的身上，即可使药水注入 病患者体内，若因一时疏忽而使药水滴光，将造成病患者的不便及痛苦。 With the development of modern medicine and the advancement of medicines, patients are treated with drips as soon as they are hospitalized, and various medicines are added to the drips, and almost all inpatient units are dripped. However, it takes about 4 hours for a 500 C. C. drop to drip. In particular, you need to check two or three times before the drip is finished. Observe that the number of beds in each area of the inpatient department is more than one hundred, and there are about four or five nursing staff. It is conceivable that just looking at the drip conditions will make the caregiver's workload too heavy, and it will naturally cause the caregiver's replacement work. The nurse shortage problem today. Please refer to FIG. 1. The current structure 10 of the drip bottle at the time of injection is composed of a vial 11, a ventilating needle 12, a needle 13, a drip tube 14, and a catheter 15. The catheter 15 is connected to the injection needle, and Inserting the injection needle into the patient's body can inject the medicine into the patient's body. If the medicine drips due to inattention, it will cause inconvenience and pain to the patient.
发明内容 Summary of the Invention
本发明的主要目的是提供一种空气袋式注射点滴控制瓶，它将空气袋经一导管接 至透气针，再将透气针插入药瓶内，当点滴瓶的药水快滴完时，空气袋的空气巳释放 完毕，而使空气无法进入药瓶内，因此，可制止药水继续往下滴。 本发明提供的注射 点滴装置，已达到了上述目的。 图 1所示为已知点滴瓶于注射时的剖面示意图； The main object of the present invention is to provide an air bag type injection drip control bottle, which connects the air bag to a breathable needle through a catheter, and then inserts the breathable needle into the medicine bottle. When the medicine in the drip bottle is almost finished, the air bag The release of air plutonium is completed, so that air cannot enter the medicine bottle, so the medicine can be prevented from dripping continuously. The injection drip device provided by the present invention has achieved the above object. Figure 1 is a schematic cross-sectional view of a known drip bottle during injection;

本发日 J8的是佳实施方式 J8 is the best implementation today
请参阅图 2及图 3所示本发明空气袋式注射点滴控制瓶 20，它是由一保护瓶 （或容 器形保护壳） 30、一空气袋 40、一保护瓶盖 50、一空气导管 60、一透气针 70及一透气 针保护套 71所构成，其中，该保护瓶 30为硬质村质所制成，于顶端设有孔 31，以利空
气流过,其作用乃是保护空气袋 40不受外力破坏，而影响空气袋 40的释气；于保护瓶 30内可将一空气袋 40置入，该空气袋 40以柔软不透气的物质制成，其内部装有新鲜空 气，可随释出的空气而縮小；于保护瓶 30的嘴部装设有一保护瓶盖 50,它可使空气导 管 60与保护瓶 30固定，避免空气导管 60受拉力时，影响空气袋 40的释出空气，而该空 气导管 60为一软质导管，它可连接空气袋 40与透气针 70;该透气针 70是用于插进药瓶 11内，使空气袋 40的空气进入药瓶 11内 ,·一透气针保护套 71,因本发明预先于空气袋 40内装新鲜空气，所以，需用透气针保护套 71隔绝外部空气，并保护透气针 70针头不 被污染。 Please refer to FIG. 2 and FIG. 3. The air bag injection drip control bottle 20 of the present invention is composed of a protective bottle (or container-shaped protective shell) 30, an air bag 40, a protective bottle cap 50, and an air duct 60. , A breathable needle 70 and a breathable needle protective sleeve 71, wherein the protective bottle 30 is made of hard village, and a hole 31 is provided at the top to be empty The air flow passes, and its function is to protect the air bag 40 from being damaged by external force, and affect the release of the air bag 40. An air bag 40 can be placed in the protective bottle 30. The air bag 40 is made of a soft and air-impermeable substance. The inside of the protective bottle 30 is provided with a protective bottle cap 50, which can fix the air duct 60 and the protective bottle 30 to prevent the air duct 60 from being affected by the air. When pulling, it affects the release of air from the air bag 40, and the air duct 60 is a soft duct, which can connect the air bag 40 and the vent needle 70; the vent needle 70 is used to be inserted into the medicine bottle 11 to make the air The air in the bag 40 enters the medicine bottle 11 and a breathable needle protective sleeve 71. Because the present invention pre-fills fresh air in the air bag 40, it is necessary to use the breathable needle protective sleeve 71 to isolate external air and protect the needle of the breathable needle 70 Contaminated.
当注射点滴时，将本发明的透气针保护套 71拔除，而将透气针 70插进药瓶 11内， 当药瓶 11 药水下滴渐少时，相对的空气袋 40内的空气也渐少， （空气袋也渐縮小） 。 药瓶 11内的药水将滴尽时,空气袋 40内的空气已释完，由于空气袋内的空气体积小于 药瓶内容积，因而使药瓶 11无空气进入，因此药瓶 11会保留少许的药水而不会继续再 滴。
When the drip is injected, the breathable needle protective sleeve 71 of the present invention is pulled out, and the breathable needle 70 is inserted into the medicine bottle 11. When the medicine bottle 11 drops less medicine, the air in the corresponding air bag 40 is gradually reduced. (The air bag is also shrinking). When the medicine in the vial 11 is completely drained, the air in the air bag 40 has been released. Since the volume of the air in the air bag is smaller than the inner volume of the vial, the vial 11 has no air to enter, so the vial 11 will retain a little The potion without continuing to drip.
