技术领域technical field
本发明涉及一种医用氧气袋供氧量控制装置，尤其涉及一种用于医用氧气袋供氧流量控制的医疗用品。The invention relates to a device for controlling the amount of oxygen supplied by a medical oxygen bag, in particular to a medical article for controlling the flow of oxygen supplied by a medical oxygen bag.
背景技术Background technique
氧治疗技术：氧气是机体进行有氧代谢、产生能量的必需物质，氧治疗是通过不同的供氧技术，使患者的吸入氧浓度(FiO2)高于大气的氧浓度(21％)，以达到纠正机体缺氧的目的，具备医用氧源是实施氧疗技术的前提。Oxygen therapy technology: Oxygen is an essential substance for the body to carry out aerobic metabolism and generate energy. Oxygen therapy uses different oxygen supply technologies to make the patient's inhaled oxygen concentration (FiO 2 ) higher than the atmospheric oxygen concentration (21%) to To achieve the purpose of correcting the body's hypoxia, having a medical oxygen source is the prerequisite for the implementation of oxygen therapy technology.
医用氧源：目前医院实施临床供氧的氧源主要包括低温液氧罐、氧气钢瓶、氧气袋等。低温液氧罐(-183℃，1MPa)储氧量很高，容积为1m3的液氧罐可释放常压氧气容量约为860m3，该设备使用流程较复杂，一般安装在医院的氧气站作为中心供氧氧源使用。医院常用的40L氧气钢瓶为高压氧源(最高工作压力15MPa)，可释放常压氧气容量约为6000L，氧气钢瓶具有储氧量高、可供氧时间长的特点，但是该设备存在重量大(50kg以上)、不易移动、需要使用专用高压设备充氧等缺点，因此一般多作为固定氧源或中心供氧氧源使用。小型氧气钢瓶可作为移动使用的临时供氧氧源，但是该设备同样存在重量较大、需要使用专用高压设备充氧等缺点，一般只作为呼吸机临时供氧的氧源使用。医用氧气袋属于低压氧源，具有充氧便捷、重量轻、便于移动使用等特点，但是其储氧量较少，常作为短时间临时供氧的氧源使用。Medical oxygen source: At present, the oxygen source for clinical oxygen supply in hospitals mainly includes cryogenic liquid oxygen tanks, oxygen cylinders, oxygen bags, etc. The low-temperature liquid oxygen tank (-183°C, 1MPa) has a high oxygen storage capacity. A liquid oxygen tank with a volume of 1m 3 can release about 860m 3 of normal pressure oxygen. The use process of this equipment is complicated, and it is generally installed in the oxygen station of the hospital. Used as a central oxygen supply source. The 40L oxygen cylinder commonly used in hospitals is a high-pressure oxygen source (maximum working pressure 15MPa), which can release about 6000L of normal pressure oxygen. The oxygen cylinder has the characteristics of high oxygen storage capacity and long oxygen supply time, but the equipment has a large weight ( More than 50kg), not easy to move, need to use special high-pressure equipment for oxygenation, etc., so it is generally used as a fixed oxygen source or a central oxygen supply source. Small oxygen cylinders can be used as a temporary oxygen source for mobile use, but this equipment also has the disadvantages of heavy weight and the need to use special high-pressure equipment for oxygenation. Generally, it is only used as an oxygen source for temporary oxygen supply for ventilators. The medical oxygen bag is a low-pressure oxygen source, which has the characteristics of convenient oxygenation, light weight, and easy mobile use. However, its oxygen storage capacity is small, and it is often used as an oxygen source for short-term temporary oxygen supply.
医用氧气袋供氧技术：目前医用氧气袋是临床最常用的低压可移动氧源。在没有高容量氧源的医疗区域中(例如在危重病人的转运过程中)，应用医用氧气袋为病人吸氧，是目前临床实施临时供氧的主要方式。国产50L医用氧气袋最大限度充满后(最高工作压力10kp)，常压氧气容量一般是55L左右，一般可使用20min左右。Medical oxygen bag oxygen supply technology: At present, medical oxygen bag is the most commonly used low-pressure portable oxygen source in clinical practice. In medical areas without high-capacity oxygen sources (for example, during the transfer of critically ill patients), the application of medical oxygen bags to inhale oxygen for patients is currently the main way of clinically implementing temporary oxygen supply. After the domestic 50L medical oxygen bag is fully filled (maximum working pressure 10kp), the normal pressure oxygen capacity is generally about 55L, and it can generally be used for about 20 minutes.
现有医用氧气袋供氧技术的缺点：氧气袋属于低压氧源，不具备氧气自动输出的功能，临床常用人工挤压方法来维持氧气的输出，通常其供氧流量难以恒定。因此，现有氧气袋供氧技术存在需要人工挤压、供氧流量不稳定、有效供氧时间不确定等弊端。Disadvantages of the existing medical oxygen bag oxygen supply technology: the oxygen bag is a low-pressure oxygen source, and does not have the function of automatic oxygen output. Clinically, manual extrusion is often used to maintain the oxygen output. Usually, the oxygen supply flow rate is difficult to maintain. Therefore, the existing oxygen bag oxygen supply technology has disadvantages such as manual extrusion, unstable oxygen supply flow rate, and uncertain effective oxygen supply time.
医用氧气袋供氧的改进技术：2016年12月，王凤卿公开了急救氧气袋辅助装置(CN205796184U),包括板框、第一挤压机构及第二挤压机构，将氧气袋放入装置内使得氧气袋能够保持持续地输出；2017年4月，曹兴华公开了医用氧气袋压力器(CN206081250U),在氧气袋袋体上增设夹层袋体,呼吸气囊头端设置呼出气体收集器,利用呼出的气体将夹层袋体吹起,从而产生压力,自动压缩氧气袋对呼吸气囊进行补充氧气；2018年2月，王洁等公开了一种可自动增压和可调控气体流量的氧气袋(CN206964858U),包括外罩、弹簧、下压板、氧气袋、出气口、可调控阀门、出气导管等结构，将氧气袋放入该实用新型的外罩内，可实现氧气袋的增压效果，并通过可调控阀门调控氧气的输出流量。Improvement technology of medical oxygen bag oxygen supply: In December 2016, Wang Fengqing disclosed the emergency oxygen bag auxiliary device (CN205796184U), including a plate frame, a first extrusion mechanism and a second extrusion mechanism, and the oxygen bag is put into the device so that The oxygen bag can maintain a continuous output; in April 2017, Cao Xinghua disclosed a medical oxygen bag pressure device (CN206081250U), which added a sandwich bag body to the oxygen bag body, and installed an exhaled gas collector at the head end of the breathing air bag to utilize the exhaled gas The interlayer bag is blown up to generate pressure, and the oxygen bag is automatically compressed to supplement the breathing airbag; in February 2018, Wang Jie et al. disclosed an oxygen bag that can automatically pressurize and control the gas flow (CN206964858U), Including outer cover, spring, lower pressure plate, oxygen bag, air outlet, adjustable valve, air outlet duct and other structures, putting the oxygen bag into the outer cover of the utility model can realize the pressurization effect of the oxygen bag, and control it through the adjustable valve Oxygen output flow.
上述改进技术的不足：上述实用新型技术均使用了外部加压方式来维持氧气袋的压力，均能克服现有技术中氧气不能自动输出的缺点，但是上述技术的工作压力难以恒定，难以解决现有的氧气袋供氧技术存在氧气输出流量不稳定、有效供氧时间不确定的弊端，而且上述设施均存在体积大、操作繁琐的缺点。Deficiencies of the above-mentioned improved technologies: the above-mentioned utility model technologies all use an external pressurization method to maintain the pressure of the oxygen bag, which can overcome the shortcomings of the prior art that oxygen cannot be automatically output, but the working pressure of the above-mentioned technologies is difficult to be constant, and it is difficult to solve the existing problems. Some oxygen bag oxygen supply technologies have the disadvantages of unstable oxygen output flow and uncertain effective oxygen supply time, and the above-mentioned facilities have the disadvantages of large volume and cumbersome operation.
