技术领域technical field
本实用新型涉及临床输液无菌医疗器械，特别是涉及一种自排气止液可净液输液器。The utility model relates to a sterile medical instrument for clinical infusion, in particular to a self-exhausting liquid-stopping liquid-purifying infusion device.
背景技术Background technique
目前，医疗领域中临床上使用普通输液主要由瓶塞穿刺器保护帽、瓶塞穿刺器、输液短导管、排气短导管、空气过滤器、滴管、滴斗、输液长导管、输液长导管、药物过滤器和一次性使用静脉针组成。在使用普通输液器输液时，必须人工挤捏滴斗，才能将药液从输液瓶引入滴斗内，在药液进入滴斗过程中，药液容易将滴斗内的气体压入输液长导管内，产生管内气泡，同时，由于输液管内壁表面张力作用，内壁上容易吸附少量气泡，排除过程困难、烦琐、费时，如果不能很好排除气泡，气泡随药液进入患者体内，易造成气栓等危险。目前医护人员在给患者输液前排气方式是：瓶塞穿刺器插入输液瓶后，倒置滴斗，用手挤捏滴斗使药液进入滴斗内，待滴斗内药液达到一定量后，放下滴斗，尽可能将大部分气泡排除，针对内壁吸附气泡，需要医护人员反复弹动输液导管，将气泡赶至滴斗内，整个过程费时、费力、烦琐，增加了医护人员的工作强度，同时在面对紧急输液和抢救病危患者时，将造成严重后果。At present, the common infusion in the medical field is mainly composed of a bottle stopper piercer protective cap, a bottle stopper piercer, a short infusion catheter, a short exhaust catheter, an air filter, a dropper, a drip funnel, a long infusion catheter, and a long infusion catheter. , a drug filter and a disposable intravenous needle. When using an ordinary infusion set for infusion, the dripping funnel must be squeezed manually to introduce the medicinal liquid from the infusion bottle into the dripping funnel. When the medicinal liquid enters the dripping funnel, the medicinal liquid will easily press the gas in the dripping funnel into the long infusion catheter At the same time, due to the surface tension of the inner wall of the infusion tube, a small amount of air bubbles are easily adsorbed on the inner wall, and the removal process is difficult, cumbersome, and time-consuming. If the air bubbles cannot be removed well, the air bubbles will enter the patient's body with the liquid medicine and easily cause air embolism. Waiting for danger. At present, the way for medical staff to exhaust air before infusion to patients is: after the cork piercer is inserted into the infusion bottle, the dripping funnel is turned upside down, and the medicinal liquid enters the dripping funnel by squeezing the dripping funnel by hand. After the medicinal liquid in the dripping funnel reaches a certain amount, , put down the drip funnel, and remove most of the air bubbles as much as possible. For the adsorption of air bubbles on the inner wall, the medical staff needs to repeatedly flick the infusion catheter to drive the air bubbles into the drip funnel. The whole process is time-consuming, laborious, and cumbersome, which increases the work intensity of the medical staff. , At the same time, it will cause serious consequences when facing emergency infusion and rescuing critically ill patients.
而且，医护人员通常一对多的照看患者输液，劳动量、强度都十分大，输液过程中常出现因医护人员、患者或患者家属未能及时更换输液瓶或拔掉输液针，造成血液回流输液导管内或气泡进入患者体内造成气栓等不良后果，给医护人员、患者或患者家属带来沉重精神负担。Moreover, medical staff usually take care of patients with one-to-many infusions, and the workload and intensity are very large. During the infusion process, blood backflow into the infusion catheter often occurs because the medical staff, patients or family members of the patients fail to replace the infusion bottle or pull out the infusion needle in time. Inhalation or air bubbles enter the patient's body and cause adverse consequences such as air embolism, which brings a heavy mental burden to medical staff, patients or patients' families.
此外，通过改进普通输液器滴斗结构或在滴斗附近添加止液附件，虽能实现简单止液和排气，但在更换输液瓶时仍无法有效解决排气泡问题，同时，简单止液导致部分药液残留在滴斗与输液长导管内，不能很好的进入患者体内，造成治疗药液剂量不足及药液浪费，尤其是在紧急抢救病危患者需要输入少剂量、昂贵救命药液时，将造成严重后果。In addition, by improving the structure of the dripping funnel of ordinary infusion sets or adding liquid-stopping accessories near the dripping funnel, although simple liquid-stopping and exhaust can be achieved, the problem of air bubbles cannot be effectively solved when changing infusion bottles. At the same time, simple liquid-stopping As a result, part of the medicinal liquid remains in the dripping funnel and the long infusion catheter, which cannot enter the patient's body well, resulting in insufficient dosage of therapeutic medicinal liquid and waste of medicinal liquid, especially when emergency rescue of critically ill patients requires a small dose of expensive life-saving medicinal liquid , will have serious consequences.
因此，针对上述普通输液器及改进输液器存在的问题，在临床输液过程中，使用一种具备自动排气、自动止液和输液管净液功能的输液器尤为重要。Therefore, aiming at the problems existing in the above-mentioned common infusion set and the improved infusion set, it is particularly important to use an infusion set with the functions of automatic exhaust, automatic liquid stop and infusion tube cleaning in the clinical infusion process.

At this time, the residual air in the dripping funnel 07 and the air filtering membrane 19 are also isolated by the medicinal liquid and no longer discharged from the dripping funnel 07. Then the medicinal liquid continues to drip into the dripping funnel 07. The space in the bucket 07 gradually decreases, and the residual air will generate pressure. When the pressure generated by the residual air is enough to prevent the liquid medicine from dripping in, the liquid level of the liquid medicine in the dropping bucket will no longer rise;
步骤五：当药液液面没过限位器18底端内孔上的空气过滤膜19并不再上升时，即可调节控制流量器12，使药液进入输液长导管11并从一次性静脉输液针流出15，排净输液长导管11内气体，关闭流量调节器12，穿刺静脉输液针15，然后再打开流量调节器12，调节好流量，即可正常输液；Step 5: When the liquid level of the medicinal liquid has not crossed the air filter membrane 19 on the inner hole at the bottom of the limiter 18 and no longer rises, the control flow device 12 can be adjusted so that the medicinal liquid enters the long transfusion catheter 11 and is discharged from the disposable The intravenous infusion needle flows out 15, drains the gas in the long infusion catheter 11, closes the flow regulator 12, punctures the intravenous infusion needle 15, and then opens the flow regulator 12, adjusts the flow rate, and the infusion can be normal;
步骤六：输液瓶内药液输完时，残留药液全部进入滴斗07下腔、滴斗底座10内部和输液长导管11中，由于分隔层21上的止液膜20被浸湿后不通气，滴斗下腔、滴斗底座内部和输液长导管中药液在负压作用下自动停止流动并停留在滴斗07下腔、滴斗底座10内部和输液长导管11中，达到自动止液的目的，同时由于自动止液发挥作用，阻止空气进入输液管路，无需担心更换不及时导致血液回流或气体进入患者体内形成气栓，减少医护人员、患者和患者家属的沉重精神负担；Step 6: When the liquid medicine in the infusion bottle is transfused, all the remaining liquid medicine enters the lower cavity of the drip funnel 07, the inside of the base 10 of the drip funnel, and the long infusion conduit 11. Since the liquid stop film 20 on the separation layer 21 is soaked, it will not Ventilation, the lower chamber of the drip funnel, the inside of the base of the drip funnel and the long infusion catheter automatically stop the flow of the traditional Chinese medicine under the action of negative pressure and stay in the lower chamber of the drip funnel 07, the inside of the base 10 of the drip funnel and the long infusion catheter 11 to achieve automatic stop. At the same time, due to the function of automatic liquid stopper, it prevents air from entering the infusion line, so there is no need to worry about blood backflow or gas entering the patient's body to form an air embolism if the replacement is not timely, reducing the heavy mental burden of medical staff, patients and patients' families;
步骤七：由于自动止液存在，输液长导管11内残留部分药液，此时在护士安全操作下，将滴斗底座10左侧的气塞08打开，除去负压作用，使自动止液作用失效，输完停留在滴斗底座10内部和输液长导管11中的残留药液，由于输液器自动净液功能的存在，有效避免了药液不能很好的进入患者体内，造成治疗药液剂量不足及药液浪费，尤其是在紧急抢救病危患者需要输入少剂量、昂贵救命药液时，将造成严重后果。Step 7: Due to the existence of the automatic liquid stop, part of the liquid medicine remains in the long infusion catheter 11. At this time, under the safe operation of the nurse, open the air plug 08 on the left side of the drip funnel base 10 to remove the negative pressure and enable the automatic liquid stop function. Ineffective, the residual liquid medicine staying inside the base 10 of the drip funnel and the long infusion tube 11 after infusion, due to the existence of the automatic liquid cleaning function of the infusion set, effectively prevents the liquid medicine from entering the patient's body well, resulting in a large dose of the medicinal liquid for treatment. Insufficient and waste of medicinal liquid, especially when urgently rescuing critically ill patients need to input small doses of expensive life-saving medicinal liquid, will cause serious consequences.
