Description

Technical Field

[0001] The utility model relates to the field of medical products, in particular to a blood bag. Background Art

[0002] A blood transfusion bag is a tool used for blood storage and transfusion. Infusing blood into a patient through a vein is a commonly used treatment method in medical treatment. Existing blood transfusion bags have the following problems when in use: the bag body of the blood bag is made of soft plastic. When the needle of the blood transfusion device is inserted into the blood bag, the needle can easily puncture the bag body, causing blood to flow out, which not only causes pollution problems, but also causes blood waste. In addition, the blood in the blood bag sometimes clumps, which makes it difficult to filter and guide the blood, affecting the efficiency of blood transfusion. Utility Model Content

[0003] In view of this, in order to solve the problems existing in the technical background, the utility model proposes a blood bag, and the specific technical solution is as follows:

[0004] A blood bag comprises a bag body, one end of which is provided with an extension interface, the extension interface is connected to a blood transfusion device through a connector, and a filter is provided inside the bag body near the extension interface to filter agglomerates in the blood to prevent the agglomerates from clogging the extension interface;

[0005] A placement bag is provided on one side of the bag body, a radio frequency tag is placed in the placement bag, and the radio frequency tag stores the information of the blood bag.

[0006] Furthermore, the connecting piece includes a joint, a needle and fins. The joint is connected to the needle. Fins are provided on both sides of the joint to facilitate holding the joint.

[0007] Furthermore, the length of the needle is shorter than the length of the extension interface to prevent the needle from being inserted into the bag body.

[0008] Furthermore, the filter screen is shaped with inclined sides, so as to guide the agglomerates to both sides, thereby preventing the agglomerates from clogging in the middle and causing poor blood delivery.

[0009] Furthermore, the bag body is made of a transparent material and is provided with scale lines.

[0010] Furthermore, a hanging hole is provided at the bottom of the bag body for easy hanging.

[0011] The above technical solution has the following beneficial effects:

[0012] The bag body of the utility model is provided with an extension interface. When a blood transfusion device is inserted, since the length of the extension interface is greater than the length of the needle of the blood transfusion device, the needle is not easy to pierce the bag body. A filter is provided in the bag body to filter agglomerates in the blood to prevent the agglomerates from clogging the extension interface. In addition, a radio frequency tag is placed in the bag. The radio frequency tag contains blood information and can be taken out, so that the tag can be reused and resources can be saved. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] Embodiment 1, the following will be combined with the drawings in the embodiment of the utility model to clearly and completely describe the technical scheme in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In this embodiment, refer to Figure 1-2The blood bag shown in the figure comprises a transparent bag body 1. When in use, the hanging hole 11 of the bag body 1 faces upward, and the extension interface 2 on the bag body 1 faces downward. One end of the bag body 1 is provided with an extension interface 2, and the extension interface 2 is connected to a blood transfusion device 3 through a connector. A filter net 7 is provided near the extension interface 2 inside the bag body 1 to filter agglomerates in the blood to prevent the agglomerates from clogging the extension interface 2; one side of the bag body 1 is provided with a placement bag 9, and a radio frequency tag 10 is placed in the placement bag 9, and the radio frequency tag 10 stores the blood bag Information, the connecting part includes a connector 4, a needle 5 and a fin 6, the connector 4 is connected to the needle 5, and fins 6 are provided on both sides of the connector 4 to facilitate holding the connector 4, the length of the needle 5 is less than the length of the extension interface 2 to prevent the needle 5 from being inserted into the bag body 1, the filter screen 7 is inclined on both sides to guide the agglomerates to both sides to avoid agglomerates being blocked in the middle and causing blood delivery to be unsmooth, the bag body 1 is made of transparent material, and scale lines 8 are provided on the bag body 1, and a hanging hole 11 is opened at the bottom of the bag body 1 for easy hanging.

[0021] like Figure 2 The figure shows an enlarged view of the connector, in which the tip of the needle 5 is inserted into the extension interface 2. The length of the bag body 1 in this embodiment is 30 cm. When performing a blood transfusion, the needle 5 of the blood transfusion device 3 is inserted into the extension interface 2. The bag body 1 is provided with an extension interface 2. When the blood transfusion device 3 is inserted, since the length of the extension interface 2 is greater than the length of the needle 5 of the blood transfusion device 3, the needle 5 is not easy to pierce the bag body 1. A filter screen 7 is provided in the bag body 1. The needle 5 in this embodiment is tapered to facilitate insertion into the extension connector 4.

[0022] Embodiment 2, as Figure 3 and Figure 4 As shown, the difference between this embodiment and embodiment 1 is that both sides of the bag body 1 are provided with extension interfaces 2, and the extension interfaces 2 are connected to the blood transfusion device 3 through a connector. When in specific use, the extension interface 2 on one side can be used as a spare. In addition, a sealing layer 12 is provided inside the extension interface 2 of this embodiment. The sealing layer is made of plastic to increase the sealing effect. When the needle 5 is inserted into the extension interface 2, the sealing layer 12 needs to be pierced.

[0023] The extension interface 2 is used to filter the agglomerates in the blood to prevent the agglomerates from clogging the extension interface 2. In addition, the radio frequency tag 10 is placed in the placement bag 9. The radio frequency tag 10 contains blood information and can be taken out to facilitate the reuse of the tag 10. The extension interface 2 is placed downward and the blood transfusion bag is hung high.
