Description

Double-layer medical fluid bag

This creation is about a medical fluid bag, especially a two-layer medical fluid bag that ensures safety.

Press, in the medical environment, the most common picture is the scene of injection. It is often seen that the patient is lying on the hospital bed or sitting in a wheelchair. 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. The outer skin is filled with a medical liquid (for example, a drip solution, a physiological saline solution, etc.), and a flexible block 11 is attached to the bottom of the drip bag 1, for example, a rubber block body, and a connector 12 is provided. Inserting the flexible block 11 , the nozzle of the connector 12 enters the drip bag 1 , and the back end is connected with a drop tube 13 . When used, the pressure inside and outside of the drip bag 1 is balanced, and a fine inner portion is utilized. The ventilating needle 14 of the diameter is inserted through the wall of the drip bag 1, and the needle is inserted into the space above the liquid medicine filled in the drip bag 1. The back end of the drip tube 13 is connected to an infusion tube 15 to the lower end. An injection needle (not shown) is used to inject the medical fluid into the patient's arm.

The creator is very concerned about medical work and working environment. When using the conventional drip bag 1, a venting needle 14 must be inserted to pass the gas, so that the pressure inside and outside the drip bag 1 is balanced to facilitate loading. The way the liquid medicine is slowly dripped out is deeply understood, but it is believed that this part should be improved. The creator believes that the medical fluid bag is used in a medical work environment, often in a ward or an emergency room, especially an emergency room, and is an extremely busy, complicated, crowded, and polluted environment, so the vent needle 14 Immediately after the packaging is opened, it is immediately in the air filled with bacterial viruses, and in the medical environment, the air filled with bacterial viruses enters the drip bag 1, which is accompanied by an unpredictable danger. 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 vent needle 14 must be inserted to introduce gas, which may cause an unidentified infection. The creator conceived that a medical device constructed as an inner and outer double-layer wall can be created. The liquid bag is filled with clean air between the outer wall and the inner wall, and a piercing device is disposed between the outer wall and the inner wall, when the medical liquid in the medical liquid bag is to be used. The puncture device is advanced to puncture a piece to be punctured, so that clean air can slowly enter the inner wall to push the liquid downward. This completely avoids the danger of unidentified outside air entering to ensure the safety of use and to improve the above-mentioned deficiency. Based on this demand, the creator has carried out in-depth research and development and improvement, and after many efforts, the creation of this creation.
