The manpower required to extract and inject the drug solution is generally provided by the hand. Because the hand strength of female medical staff is weak, the current syringe will be more difficult if it requires one-handed operation, and often the measurement liquid is inaccurate due to poor control.
输液是一种被广泛应用的治疗方法,在进行输液之前,经常需要配制一些药液,目前,药粉与药剂的配制一般采用注射器来完成,具体的操作为,将注射器插入药液瓶中抽取少量的药液,然后拔出注射器并插入药粉瓶中,把药液注入药粉瓶中,待药粉与药液完全溶解后,再抽出混合液注入输液瓶内,在配药过程中,由于药瓶为密封结构,因此操作时会产生一定的负压差,使操作费力。Infusion is a widely used treatment. It is often necessary to prepare some liquids before infusion. At present, the preparation of powders and medicaments is generally done by syringe. The specific operation is to insert the syringe into the liquid bottle and take a small amount. The liquid medicine is then pulled out of the syringe and inserted into the powder bottle, and the medicine liquid is injected into the powder bottle. After the medicine powder and the medicine liquid are completely dissolved, the mixture is extracted and injected into the infusion bottle. During the dispensing process, the medicine bottle is sealed. Structure, so a certain negative pressure difference will occur during operation, making the operation laborious.

当将5ml溶液A和7ml药液B需要混合在30ml的0.04%生理盐水中,然后将混合好的药液倒入输液导管中加入至300ml的注射液中。将沿着辅助推杆一侧箭头指示方向相反的方向滑动导向滑块(35)、当第一凸台(314)和第二凸台(327)刚脱离导向滑块(35),导向滑块(35)沿着远离溶药筒固定机构(3)方向抽拉,于此同时辅助推杆(33)向外移动,当辅助推杆的刻度指示为42ml时停止抽拉导向滑块。然后将溶药筒一端的衔接部(11)连通盛有溶液A的容器。当溶药筒衔接部与盛有A的容器连通后,将导向滑块(35)向着靠近溶药筒固定机构方向推动、进而带动辅助推杆(3)向着靠近溶药筒固定机构推动7ml(此时刻度显示35ml)-此时在溶药筒内就盛有7ml的药液A。然后先将溶药筒的衔接部连通盛有药液B的容器后、推动导向滑块(35)向着靠近固定机构(3)的方向直至辅助推杆(33)的刻度显示为30ml,此时溶药筒内含有7ml药液A和5ml药液B,用医学针筒盖帽盖住溶药筒衔接部、用手腕晃动溶药筒使得两种药液混合均匀;然后再将溶药筒的衔接部连通0.04%生理盐水的容器,最后再次推动导向滑块(35)直至辅助推杆刻度显示原点(0ml)。此时溶药筒含有7ml药液A、5ml药液B和30ml
0.04%(w/w)的生理盐水,摇晃溶药器使之充分混合。本发明的溶药器能精确量取不同的药物、并混合均匀,然后投入使用。本实施例将混合好的42ml药液通过溶药通过衔接部退入300ml注射液中即可。When 5 ml of the solution A and 7 ml of the drug solution B were mixed in 30 ml of 0.04% physiological saline, the mixed drug solution was poured into an infusion catheter and added to 300 ml of the injection solution. Slide the guide slider (35) in the direction opposite to the direction indicated by the arrow on the side of the auxiliary push rod. When the first boss (314) and the second boss (327) are just separated from the guide slider (35), the guide slider (35) Pulling away from the cartridge fixing mechanism (3), while the auxiliary pusher (33) moves outward, and stops pulling the guide slider when the scale of the auxiliary pusher is 42 ml. The adapter (11) at one end of the drug cartridge is then connected to a container containing solution A. When the solvent cartridge connection portion communicates with the container containing A, the guide slider (35) is pushed toward the solvent cartridge fixing mechanism, and then the auxiliary push rod (3) is pushed toward the solvent cartridge fixing mechanism to push 7 ml ( At this time, the scale shows 35 ml) - at this time, 7 ml of the drug solution A is contained in the drug cartridge. Then, after the connecting portion of the solvent cartridge is connected to the container containing the liquid medicine B, the guide slider (35) is pushed toward the fixing mechanism (3) until the scale of the auxiliary push rod (33) is displayed as 30 ml. The dissolved cartridge contains 7ml of the liquid A and 5ml of the liquid B, and the medical syringe cap is used to cover the connecting portion of the solvent tube, and the solvent is shaken by the wrist to make the two liquids evenly mixed; The container is connected to 0.04% saline, and finally the guide slider (35) is pushed again until the auxiliary pusher scale shows the origin (0 ml). At this time, the drug cartridge contains 7ml of liquid A, 5ml of liquid B and 30ml.
0.04% (w/w) of physiological saline was shaken to make it thoroughly mixed. The drug dissolver of the present invention can accurately measure different drugs, mix them uniformly, and then put them into use. In this embodiment, the mixed 42 ml of the drug solution can be retreated into the 300 ml injection solution through the junction portion by dissolution.
