There is a drop frame on the side of the drop stand, and a drop bag is hung on the top of the drop stand. An infusion tube is connected under the drip bag, and the liquid medicine in the drip bag is injected into the patient through the infusion tube for treatment behavior. In the scene of the injection, the drip bag is one of the name of the medical "medical fluid bag". Others, in the blood donation operation, the blood of the donor is pumped into a blood bag, so "blood The bag is also a type of "medical fluid bag". Therefore, it can be used to store medical-related fluids in medical-related scenes or operations (eg, liquid medicine, blood, physiological saline, and electrolytic supplement water). --- etc.), and the bag that can be released for use is included in the creation name "medical fluid bag".

For the use of the medical medical fluid bag, for example, as shown in Fig. 1, a drip bag 1 is hung on a drop holder 2, which has a single layer of toughness and flexibility.

Although modern medical treatment has been extremely advanced, it is often heard that patients suddenly die in the hospital and suddenly die. These patients are almost all day long, but under strict medical protection, first aid will still be invalid. In this case, one has to suspect that the risk of an unknown infection may be caused when the venting needle 14 is inserted.

When the conventional drip bag 1 is used, the venting needle 14 must be inserted to pass the gas, which may cause an unidentified infection. The creator conceived that if the vent needle is combined with a clean air at the rear end of the vent needle, The medical liquid bag composed of the material, when the medical liquid in the medical liquid bag is to be used, the venting needle is inserted into the medical liquid bag, which is favorable for the outside air to pass in to maintain the pressure balance, and the characteristic is that the outside world enters The air is filtered through the air cleaning material, so that it is clean air when it is passed into the medical fluid bag.
