[0002] Blood is an indispensable component for the functioning of the human body. It circulates in the heart and blood vessels. During surgery, patients often lose a lot of blood. In order to ensure the clinical blood supply demand, hospitals should stockpile blood for emergency use. Blood transfusion is a method of replenishing blood for the body after illness or injury. Blood transfusion generally takes one to four hours, depending on the amount of blood required. Blood transfusion is usually normal. Blood transfusion is a more important medical method. Blood transfusion is usually done in blood bags for easy storage and use. Therefore, the quality of blood transfusion bags is particularly important.

[0003] During use, the blood transfusion bag cannot stop the flow in time, so when the patient stops the blood transfusion, the blood is discarded and the flow cannot be stopped and recovered in time, which easily leads to the pollution of blood resources. Therefore, a blood transfusion bag with a stop flow function is proposed to solve the above problem. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a blood transfusion bag with a flow-stopping function, which has the advantages of timely flow-stopping and solves the problem of blood contamination.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] 1. The blood transfusion bag with the flow-stopping function is provided with a flow-stopping structure. When the blood transfusion bag is used, the blood transfusion device is connected to the fixed tube. When the flow needs to be stopped, the adjusting handle is rotated a quarter of a turn, so that the adjusting handle drives the flow-stopping plate to rotate along the rotating axis. During the rotation, the sealing strip moves along the outer surface of the baffle plate until the outer surface of the flow-stopping plate contacts the limit block, thereby closing the fixed tube. When it needs to be reopened, the adjusting handle is rotated in the opposite direction, and the flow-stopping plate passes through the limit block, allowing blood to be transfused through the flow-stopping plate again, thereby achieving the flow-stopping effect.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0024] See also Figure 1-3 In this embodiment, a blood transfusion bag with a flow-stopping function comprises a bag body 1, a hanging ring 2 is fixedly installed on the top of the bag body 1, a first through hole 3 is opened on the top of the hanging ring 2, a flow-stopping structure 4 is arranged at the bottom of the bag body 1, a scale line 5 is arranged on the front side of the bag body 1, a first blood bag pipeline 6 is fixedly connected to the bottom of the bag body 1, a second blood bag pipeline 7 is fixedly connected to the bottom of the bag body 1, and the flow-stopping structure 4 comprises a fixed tube 401, an adjustment handle 402, a flow-stopping plate 403, a sealing strip 404, a grid A baffle 405, a rotating shaft 406 and a limit block 407, a fixed tube 401 is fixedly installed on the bottom of the bag body 1, an adjusting handle 402 is arranged inside the fixed tube 401, a stop plate 403 is fixedly installed inside the adjusting handle 402, a sealing strip 404 is arranged below the stop plate 403, a baffle 405 is fixedly installed on the inner wall of the fixed tube 401, a rotating shaft 406 is arranged inside the stop plate 403, and a limit block 407 is fixedly installed on the inner wall of the fixed tube 401.

[0025] like Figure 1 and Figure 2 As shown, the hanging ring 2 is set as a semicircular ring structure, and the fixed tube 401 is set as a cylindrical structure. The hanging ring 2 can place the bag body 1 at a high place. The hanging ring 2 is fixed at a protruding position at any position, so that the blood moves downward under the pressure of gravity, and at the same time, the patient can be given a blood transfusion function.

[0026] like Figure 1 and Figure 3 As shown, the diameter of the fixed tube 401 is set to six millimeters, and the bottom length of the fixed tube 401 is greater than the length of the needle of the blood transfusion device. The blood inside the bag body 1 flows into the fixed tube 401 from the connection with the fixed tube 401, and the flow-stopping structure 4 is opened at the same time, so that the blood can enter the blood transfusion device through the fixed tube 401 to perform blood transfusion on the patient.

[0027] like Figure 1 and Figure 2 As shown, a plug is fixedly installed at the bottom of the fixed tube 401, and the diameter of the adjusting handle 402 is larger than the diameter of the fixed tube 401. The adjusting handle 402 is rotated a quarter of a turn, so that the adjusting handle 402 drives the stop plate 403 to rotate along the rotating shaft 406. During the rotation, the sealing strip 404 moves along the outer surface of the baffle plate 405 until the outer surface of the stop plate 403 contacts the limit block 407, thereby closing the fixed tube 401.

[0028] like Figure 2 and Figure 3 As shown, the edge of the stop plate 403 is set in an arc shape, and the stop plate 403 is symmetrically set with two groups of fan-shaped structures. The stop plate 403 rotates on the inner wall of the adjusting handle 402, and the arc is in contact with the inner wall of the adjusting handle 402 to block the blood. At the same time, the fan-shaped structure enables the adjusting handle 402 to stop the flow by rotating only a quarter of a turn. In a crisis situation, the flow can be stopped more quickly. The inner diameter of the adjusting handle 402 is larger than the inner diameter of the fixed tube 401. When the stop plate 403 is opened, the blood can pass smoothly.

[0029] like Figure 2 and Figure 3 As shown, the rotating shaft 406 and the stop plate 403 are set to be rotatably connected, and the outer surface of the adjusting handle 402 is set to be an anti-slip structure. The outer surface of the adjusting handle 402 is provided with an anti-slip design to ensure that when in use, even if the doctor or nurse has water or other liquids on his hands, the stop structure 4 can also be controlled. The rotating shaft 406 provides support for the stop plate 403 and the sealing strip 404, so that the two can rotate inside the fixed tube 401. The maximum diameter of the adjusting handle 402 is ten millimeters. When the stop plate 403 rotates, the area vacated by the two fan-shaped stop plates 403 is about forty square millimeters for blood to flow through.

[0030] like Figure 1 and Figure 2 As shown, the top of the flow-stopping structure 4 penetrates the bag body 1 and extends to the interior of the bag body 1. The flow-stopping structure 4 is made of PVC material, which can reduce the impact on the blood and ensure that the blood maintains its original activity level before entering the patient's body.

[0031] When implementing, follow these steps:

[0032] 1) First, connect the first through hole 3 of the hanging ring 2 and the protruding position of the infusion stand;

[0033] 2) The doctor or nurse then checks the information on the bag 1 and determines the position of the scale line 5;

[0034] 3) The blood transfusion device is then connected to the fixed tube 401 to transport blood so that the blood enters the patient's body;

[0035] 4) Finally, when flow stopping is required, the adjusting handle 402 is rotated a quarter of a turn, and the adjusting handle 402 drives the flow stopping plate 403 to rotate along the rotating shaft 406, and the outer surface of the flow stopping plate 403 contacts the limit block 407, thereby closing the fixed pipe 401.

[0036] In summary, the blood transfusion bag with the flow-stopping function is provided with the flow-stopping structure 4. When the blood transfusion bag is used, the blood transfusion device is connected to the fixed tube 401. When the flow needs to be stopped, the adjusting handle 402 is rotated a quarter of a turn, so that the adjusting handle 402 drives the flow-stopping plate 403 to rotate along the rotating shaft 406. During the rotation, the sealing strip 404 moves along the outer surface of the baffle plate 405 until the outer surface of the flow-stopping plate 403 contacts the limit block 407, thereby closing the fixed tube 401 and completing the flow-stopping effect. When it is necessary to reopen, the adjusting handle 402 is rotated in the opposite direction, and the flow-stopping plate 403 passes the limit block 407, allowing the blood to be transfused again through the flow-stopping plate 403. The blood transfusion bag with the flow-stopping function is provided with a fixed tube 401, and the fixed tube 401 is fixedly connected to the bag body 1. When the blood transfusion bag is used, the blood transfusion set is passed through the stopper and enters the fixed tube 401, so that the top of the blood transfusion set is under the flow-stopping plate 403. When the flow-stopping plate 403 is rotated, the flow-stopping structure 4 is closed, and the blood transfusion set will not be touched during the rotation. After the blood transfusion is completed, the blood transfusion set is pulled out, and the adjustment handle 402 is rotated to close the flow-stopping structure 4, thereby completing the sealing function of the blood transfusion bag.
