Disposable automatic control transfusion device

Abstract

The invention relates to the field of medical instruments, in particular to a disposable automatic control transfusion device. The disposable automatic control transfusion device comprises a bottle plug puncture outfit, a dropper, a catheter and a vein needle. A flow controller is arranged on the catheter. The disposable automatic control transfusion device is characterized in that the disposable automatic control transfusion device further comprises a multifunctional automatic control device, and the bottle plug puncture outfit is communicated with the vein needle sequentially through the dropper, the multifunctional automatic control device and the catheter. The disposable automatic control transfusion device can automatically exhaust air, also can prolong transfusion time, and is safe and reliable.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a disposable self-control transfusion device. Background technique [0002] When the traditional disposable infusion set is used for clinical infusion, the liquid medicine enters the drip funnel, and the liquid easily discharges the gas in the drip funnel downward to form a gas-liquid mixture into the infusion catheter, thus generating air bubbles. At the same time, due to the surface tension of the inner wall of the catheter , it is very easy to form small bubbles on the inner wall of the adsorption catheter, which is not easy to discharge. If the generated bubbles enter the patient's body, it is easy to cause air embolism and other hazards. As mentioned above, before the infusion, the medical staff must remove the air bubbles in the catheter as much as possible.

Problems solved by technology

[0002] When the traditional disposable infusion set is used for clinical infusion, the liquid medicine enters the drip funnel, and the liquid easily discharges the gas in the drip funnel downward to form a gas-liquid mixture into the infusion catheter, thus generating air bubbles. At the same time, due to the surface tension of the inner wall of the catheter , it is very easy to form small bubbles on the inner wall of the adsorption catheter, which is not easy to discharge. If the generated bubbles enter the patient's body, it is easy to cause air embolism and other hazards

As mentioned above, before the infusion, the medical staff must remove the air bubbles in the catheter as much as possible. During the process of artificially discharging the air bubbles, the small air bubbles adsorbed on the inner wall of the catheter need to be flicked continuously on the outer wall of the catheter, so that the adsorbed small air bubbles float up to the dripping funnel. Above the inner liquid level, but the small bubbles are easily adsorbed on the inner wall of the catheter again during the floating process, resulting in tedious and time-consuming manual air bubble removal process, which is not conducive to emergency infusion and patient rescue, and at the same time increases the workload of medical staff

[0003] In addition, when the traditional disposable infusion set is used for clinical infusion, the following situations often occur: 1. When the infusion is about to end, because of fear of air entering the infusion catheter, the infusion venous needle is often pulled out before the liquid medicine is infused. There is usually a part of the liquid medicine left in the liquid medicine bottle, so the therapeutic effect cannot be achieved, and even disputes are caused by wasting the patient's medicine

2. After the liquid medicine has finished flowing, sometimes the patient forgets to pull out the venous needle on the patient’s body due to untimely nursing, causing air to enter the human body, causing the blood to return to the blood vessel and causing harm to the patient, thus increasing the mental pressure of the nursing staff and causing Patient panic, causing disputes between nurses and patients

3. At the end of the infusion or when the liquid medicine bottle (bag) is replaced, the nurse needs to strictly control the time of the liquid level and carry out medical treatment in time. At this time, the work of the nurse is highly tense, and sometimes even leads to clinical disputes
