[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0035] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] When the existing blood storage device is in use, medical staff connects the blood transfusion tube and the blood transfusion device, and blood enters the blood storage bag from the blood transfusion tube. When one blood storage bag is full, blood enters the second blood storage bag from the blood transfusion branch tube, and so on. The subsequent blood storage bags are reused to complete the storage of blood. After the blood exchange operation is completed, the user can fold multiple blood storage bags along the crease to the size of only one blood storage bag for transportation.

[0037] In the related art, after the blood exchange operation is completed, the blood storage device needs to be transported to a storage location. During the transportation of the blood storage device, multiple blood bags are stacked together, which will squeeze each other and are not effectively protected. They are prone to damage and other problems, causing blood samples to leak out, which has certain limitations.

[0038] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a blood storage device for blood exchange therapy. When it is needed, the blood only needs to be transported to the blood storage bag 12, and the blood enters multiple blood storage bags 12 one after another through the blood transfusion tube 13 and the U-shaped tube 21. After the blood exchange work is completed, the medical staff can hold the connecting piece 222 to flip the baffle 221 so that the connecting piece 222 and the box body 11 are abutted, and then control the insertion rod 233 to move inward by pressing the dial block 234 so that the socket on the connecting piece 222 is aligned with the insertion rod 233, and the insertion rod 233 is released. 33 can make the insertion rod 233 inserted into the connecting piece 222 to complete the insertion of the connecting piece 222. Further, the baffle 221 is effectively fixed, and then the box body 11 is turned over. Under the rotation of the rotating shaft 24, the multiple box bodies 11 are folded and the abutting parts are fitted. The user uses the press buckle 25 to fix the abutting parts of the multiple box bodies 11. The U-shaped tube 21 is now upright above the box body 11. After folding, the user can directly carry the blood storage assembly 1, and the baffle 221 will effectively protect the blood storage bag 12 during transportation.

[0039] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0040] Combination Figure 1-Figure 4The embodiment of the present application provides a blood storage device for transfusion therapy, including a blood storage component 1; the blood storage component 1 includes: a blood storage bag 12 is arranged inside a box body 11, a blood transfusion blood vessel 13 is arranged on the blood storage bag 12, a hook 14 is arranged on the box body 11, and a control valve 15 is arranged on the blood storage bag 12; an adjustment component 2 is arranged on the blood storage component 1, and the adjustment component 2 includes: a U-shaped tube 21 is arranged on the blood storage bag 12; a shell 22 is arranged on the box body 11, a baffle 221 is rotatably provided on the shell 22 through a rotating shaft 1 223, and a connecting piece 222 is provided on the baffle 221; a fixing piece 23 is provided on the box body 11, and a fixing block 231 is provided inside the fixing piece 23, and springs 232 are fixedly connected at both ends of the fixing block 231, and a plug rod 233 is fixedly connected to the spring 232, and the plug rod 233 is plugged into the connecting piece 222; a rotating shaft 24 is provided on multiple box bodies 11.

[0041] When it is needed, the user hangs the box body 11 on the rack through the hook 14, and then connects the blood transfusion tube 13 to the blood transfusion device. The blood enters the multiple blood storage bags 12 through the blood transfusion tube 13 and the U-shaped tube 21. After the blood exchange work is completed, the blood transfusion work is stopped. The medical staff can hold the connecting piece 222 to flip the baffle 221 so that the connecting piece 222 and the box body 11 are abutted, and then control the insertion rod 233 to move inward by pressing the dial block 234 so that the insertion hole on the connecting piece 222 is aligned with the insertion rod 233, and the insertion rod 233 can be released to use. The insertion rod 233 is inserted into the connecting piece 222 to complete the insertion of the connecting piece 222. Further, the baffle 221 is effectively fixed, and then the box body 11 is turned over. Under the rotation of the second shaft 24, the multiple box bodies 11 are folded and the abutment parts are fitted. The user uses the press buckle 25 to fix the abutment parts of the multiple box bodies 11. The U-shaped tube 21 is now upright above the box body 11. After folding, the user can directly carry the blood storage assembly 1, and the baffle 221 will effectively protect the blood storage bag 12 during transportation.

[0042] In some embodiments, through holes are provided at both ends of the fixing member 23 to cooperate with the movement of the insertion rod 233, and a limit block is provided at the bottom of the insertion rod 233. The through holes at both ends of the fixing member 23 are the same size as the insertion rod 233. If the size is too large, dust may enter and block the through holes. The limit block provided at the bottom of the insertion rod 233 can prevent the insertion rod 233 from extending too long from the fixing member 23 and causing dislocation.

[0043] In some embodiments, the fixing member 23 is provided with a slide groove, and the insertion rod 233 is provided with a shifting block 234, and the shifting block 234 penetrates the fixing member 23 and is slidably connected to the insertion rod 233 through the slide groove. The slide groove provided on the fixing member 23 allows the shifting block 234 to extend, and the shifting block 234 can control the horizontal movement of the insertion rod 233, so that the user can control the movement of the insertion rod 233 and improve the user's experience.

[0044] In some embodiments, the fixing member 23 and the housing 22 have the same level. The fixing member 23 and the housing 22 have the same level, so when the box body 11 is folded, the back of the box body 11 can directly abut against the housing 22, and the front side abuts against the baffle 221 to ensure that the entire device is flat when folded.

[0045] In some embodiments, a press buckle 25 is provided on the box body 11. The press buckle 25 is a joint-type plastic buckle, which is divided into two parts. The user can directly press the press buckle 25 to complete the fixed connection, so that the box body 11 is fixed after folding, preventing the folded blood storage assembly 1 from being opened due to external force during transportation.

[0046] In some embodiments, the U-shaped tube 21 is made of medical rubber material, and the U-shaped tube 21 and the blood storage bag 12 are rotatably connected through bearings and sealing rings. The medical rubber material has good deformation resistance and is soft and not easy to be damaged. When the blood storage component 1 is folded, the two ends of the U-shaped tube 21 rotate with the box body 11, and the top of the U-shaped tube 21 is deformed by arching upward, so as to prevent the U-shaped tube 21 from being damaged and broken due to bending during the folding process, resulting in leakage of blood samples and contamination of the outside world.

[0047] In some embodiments, the horizontal position of the top of the U-shaped tube 21 is higher than the box body 11. The U-shaped tube 21 will deform during the folding process, causing the top to arch. If the top height is lower than the box body 11, the U-shaped tube 21 will be squeezed and there is a risk of being torn. If the top of the U-shaped tube 21 is higher than the box body 11, the U-shaped tube can avoid the box body 11 when the box body 11 is folded, and will not be pulled.

[0048] In some embodiments, an L-shaped rod 26 is disposed on the box body 11. The L-shaped rod 26 can be wound around the blood transfusion tube 13 to prevent the blood transfusion tube 13 from being scattered and tangled.
