Detailed Description

In order to illustrate embodiments of the present invention or technical solutions in the prior art more clearly, the following description will be made in conjunction with the accompanying drawings in embodiments of the present invention to describe the technical solutions in the embodiments of the present invention clearly and completely, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Please refer to fig. 1, which is a schematic structural diagram of the novel blood transfusion bag provided by the present invention. The novel blood transfusion bag comprises a bag body 1, a fixing plate 3 arranged at the top of the bag body 1, and a bag hanging body 5 and at least one liquid storage bag 7 which are connected to the fixing plate 3. Wherein, the liquid storage bag 7 is filled with normal saline and is used for flushing the bag body 1.

Please refer to fig. 2 and fig. 3, wherein fig. 2 is a schematic structural view of the bag body and the fixing plate shown in fig. 1; fig. 3 is a schematic structural view of the top of the novel blood transfusion bag shown in fig. 1. The top of the bag body 1 has a certain thickness, and the thickness of the bag body gradually decreases from the top to the bottom, and the bag body has a structure with a thick top and a thin bottom. The top of bag body 1 is the rectangle, the width of bag body 1 bottom past the output tube 11 direction of bag body 1 reduces gradually, makes the bottom of bag body 1 is the funnel type, and like this, the blood in the bag body 1 can flow to output tube 11, can not deposit the bottom of bag body 1 and can't flow to output tube 11 avoids causing blood extravagant.

Fixed plate 3 is fixed the top of bag body 1, fixed plate 3 is rectangle, just the area of fixed plate 3 is less than the area at the top of bag body 1 is so that connect, fix a position fixed plate 3, fixed plate 3 can obtain good fixed, and then makes and fixes on fixed plate 3 the reservoir 7 obtains good fixed, can not be at will swing on the bag body 1, improved reservoir 7 with the stability of being connected of bag body 1, thereby stopped the follow reservoir 7 with the kneck seepage normal saline of bag body 1 extremely the emergence of the condition in the bag body 1.

Fig. 4 is an enlarged view of a portion a shown in fig. 1. The fixing plate 3 is provided with a liquid guide hole 31 which penetrates through the upper surface and the lower surface of the fixing plate and is communicated with the inner cavity of the bag body 1, a stop film 33 connected with the hole wall of the liquid guide hole 31 is arranged in the liquid guide hole, and the liquid storage space of the liquid storage bag 7 is separated from the inner cavity of the bag body 1 through the stop film 33. The stop film 33 is broken by pressing the liquid storage bag 7, so that the physiological saline in the liquid storage bag 7 is squeezed into the bag body 1 from the liquid guide hole 31 to flush the blood in the bag body 1, the operation is easy, and the required squeezing force is small.

The reservoir 7 is fixed on the fixed plate 3, the reservoir 7 bottom with the junction of fixed plate 3 is provided with reinforcing ring 9, reinforcing ring 9's upper and lower both ends are connected respectively the reservoir 7 with fixed plate 3 further strengthens reservoir 7 is in fixed, the location effect of fixed plate 3 makes the position of reservoir 7 is more stable, can not swing at will because its inside liquid weight.

The diameter of the inner ring of the reinforcing ring 9 is equal to the diameter of the liquid guide hole 31 so as to prevent the reinforcing ring 9 from blocking the liquid outlet of the liquid storage bag 7.
