Abstract
The utility model relates to a medical pressurized blood transfusion bag. An outer bag (1) is provided, an output hole (3) is arranged on the outer bag (1), the inner side of the outer bag (1) is provided with a soft inner bag (2), an air inlet hole (4) is arranged on the inner bag (2), and the air inlet hole is connected with an air inflating device. The utility model can continuously pressurize through inflating air, can accelerate blood transfusion speed, and particularly can satisfy the requirement of urgent blood transfusion of large blood loss patients and patients in operation.
Description
This utility model relates to a kind of medical adding pressure type transfusion bags.
At present, used transfusion bags is to belong to a kind of simple blood vessel basically in the medical treatment, mainly plays the container effect.Owing to can not pressurize, its blood output speed is slower, is unfavorable for patient's rescue.
Therefore, the purpose of this utility model provides a kind of adding pressure type transfusion bags, uses this transfusion bags, can accelerate transfusion speed.
The purpose of utility model realizes by following mode.
Adding pressure type transfusion bags, structure comprise an outer bag, and outer bag is provided with delivery outlet, and the inside of outer bag is provided with soft inner sac, and inner bag is provided with air inlet, and air inlet connects aerating device.
Can inject blood in the bag outward by the blood plasma delivery outlet on the outer bag, when outer bag inside is full of blood, soft inner sac is in shrivelled state, during blood transfusion, with aerating device by air inlet to the inner bag inner inflatable, after the inflation, inner bag progressively expands, and volume constantly increases, because the dilating effect of inner bag, promptly externally the blood plasma between bag and the inner bag produces pressure, can accelerate the output speed of blood plasma.
The adding pressure type transfusion bags that this utility model provides can be carried out persistent pressure by charging into air, can accelerate transfusion speed, especially can satisfy the needs of lose blood greatly patient and the urgent blood transfusion of surgical patient.This transfusion bags, amount of pressurization is controlled easily, and pressurization is stable, and is easy to operate; It is simple in structure, processing and manufacturing easily, and cost is low, can make disposable transfusion bags and use.
Below in conjunction with accompanying drawing this utility model is described in detail.
Accompanying drawing 1 is the structural representation of the adding pressure type transfusion bags that provides according to this utility model, and accompanying drawing 2 is structural representations of the aerating device of adding pressure type transfusion bags.
As shown in drawings, the structure of adding pressure type transfusion bags comprises an outer bag (1), and outer bag (1) is provided with delivery outlet (3), and the inside of outer bag (1) is provided with soft inner sac (2), and inner bag (2) is provided with air inlet (4), and air inlet (4) connects aerating device.
As shown in Figure 2, aerating device is made of two one-way cocks (5) and (6) of pressurizeing leather bag (7) and be located on the leather bag (7), and one-way exhaust valve (5) is connected with air inlet (4).Firmly push leather bag (7), the leather bag volume reduces, and internal pressure increases, check valve this moment (5) is opened, check valve (6) is closed, and the air in the leather bag promptly enters in the inner bag (2) by one-way exhaust valve (5) and air inlet (4), plays pressurization, when unclamping leather bag, leather bag relies on self elastic return original state, owing to be subjected to suction function, check valve (5) is closed, valve (6) is opened, and air enters in the leather bag by valve (6).
Outer bag (1) and inner bag (2) are all made with flexible plastic or soft rubber.Outer bag is identical with size with the specification of inner bag, or inner bag is slightly smaller than outer bag.Sometimes, inner bag also can be a bit larger tham outer bag.Because inner bag adopts soft material to make, therefore, no matter the size of inner bag, it is inner that inner bag all can be arranged on outer bag.
Claims (3)
1, a kind of adding pressure type transfusion bags, structure comprise an outer bag (1), and outer bag (1) is provided with delivery outlet (3), it is characterized in that: the inside of outer bag (1) is provided with soft inner sac (2), and inner bag (2) is provided with air inlet (4), and air inlet (4) connects aerating device.
2, by the described transfusion bags of claim 1, it is characterized in that: aerating device is made of two one-way cocks (5) and (6) of pressurizeing leather bag (7) and be located on the leather bag (7), and one-way exhaust valve (5) is connected with air inlet (4).
3, by claim 1 or 2 described transfusion bags, it is characterized in that: outer bag (1) and inner bag (2) are all made with flexible plastic or soft rubber.
