Double-capsule positive-pressure liquid packaging bag

Abstract

The invention discloses a double-capsule positive-pressure liquid packaging bag, and belongs to a medical medicine liquid bag. The double-capsule positive-pressure liquid packaging bag is characterized in that an internal packaging high-elasticity capsule and an external packaging bag which are of the two-layer internal and external structures are included, the internal packaging high-elasticity capsule is made of elastic film with the elongation of 8,000%-20,000% and the recovery rate of 99%-100%, a vent hole is formed in the external packaging bag, and the internal packaging high-elasticity capsule is connected with an infusion device connecting opening and an injection opening. The double-capsule positive-pressure liquid packaging bag has the advantages that the bag itself has the elastic pressure, the bag does not need to be hung at a high place and the pressure does not need to be exerted, therefore, infusion can be achieved, the dependency on the gravity and external force is cast off, auxiliary facilities such as a support for hanging an infusion bottle and a pressurizing device are saved, convenience and rapidness are achieved, and the rescue time is saved. The double-capsule positive-pressure liquid packaging bag is suitable for various places where infusion is needed and especially suitable for rescue treatment in special environments such as a field war, a natural hazard, pre-hospital care and patient transferring.

Description

technical field [0001] The invention relates to a medical liquid bag, which belongs to medical packaging equipment. Background technique [0002] For liquids packed in traditional packaging bags, the infusion bag must be raised during infusion, that is, the gravity of the liquid can be used to generate downward pressure to drip in; if the liquid needs to be poured, it must be packed in a glass bottle. During the process, there will be gas-liquid mixing, causing liquid splashing and other deficiencies. In addition, because it is difficult to find a suitable height for the infusion bag, it is difficult to meet the rescue treatment in special environments such as field wars, natural disasters, pre-hospital first aid, and patient transfer. In recent years, domestic scholars have researched and invented the A variety of pressurized infusion devices such as "double-bag pneumatic infusion device" and "self-made multi-functional pressurized infusion device" have better got rid of t...

In addition, because it is difficult to find a suitable height for the infusion bag, it is difficult to meet the rescue treatment in special environments such as field wars, natural disasters, pre-hospital first aid, and patient transfer. In recent years, domestic scholars have researched and invented the A variety of pressurized infusion devices such as "double-bag pneumatic infusion device" and "self-made multi-functional pressurized infusion device" have better got rid of the gravity dependence of traditional infusion devices, and use other non-gravity methods to generate pressure on the infused liquid. Pressure, so as to achieve the purpose of infusion

However, in practical application, it is found that the operation of the current pressurization device is complicated, and it is easy to delay the golden emergency time; in the process of treating the wounded, the critical condition requires a large amount of rapid fluid replacement, but in the case of shortage of manpower and materials, this kind of pressurization device is needed. The infusion bag is difficult to meet the needs of first aid, affecting the rescue of patients
