Description

safety blood bag

technical field

The utility model relates to a medical device, in particular to a one-time use safe sample retention blood bag.

Background technique

With the development of blood transfusion technology, ensuring the safety of blood transfusion has attracted more and more attention of blood collection and transfusion professionals. The concept of safe blood transfusion has extended from the quality control of the main links such as blood collection, inspection and storage to the quality control of various links such as voluntary blood donation promotion, blood donor screening, blood collection, and clinical transfusion. Bacterial contamination is one of the main factors threatening the safety of blood transfusion. Although the current use of multiple blood bags reduces the chance of bacterial contamination, it is still possible to cause contamination during the blood collection process due to the following reasons: the blood donor itself has a local infection focus, accompanied by other factors in the state of bacteremia, blood in the There is a small amount of bacteria in the original contamination; the skin is not thoroughly disinfected, the disinfectant that does not meet the requirements is used for disinfection, or the skin is not disinfected strictly in accordance with the operating standards, causing bacteria at the puncture site to enter the blood collection bag with the blood; the blood collection environment is poor, resulting in puncture When outside air enters the blood bag or secondary pollution after skin disinfection, the blood is polluted. Therefore, how to reduce blood bacterial contamination in the process of blood collection and transfusion has become a problem of great concern to blood collection and transfusion professionals.

Disposable blood bags are commonly used medical devices in the process of blood collection and blood transfusion, which generally include closed blood collection needles and anticoagulant whole blood bags. Anticoagulant whole blood bags can be single or multiple. Blood transfusion can be performed by connecting a blood transfusion set during blood transfusion. The disposable blood bag can play the role of single-use closed blood collection and blood transfusion, and can prevent and avoid clinical cross-infection. We also know that when blood is collected, samples are taken for analysis and testing. At present, most of the blood that enters the blood bag and the sampled blood during blood collection are manually separated, and errors such as crossing and confusion are prone to occur between the sampled blood and the blood bag label. The method of sampling blood from the blood bag is cumbersome in operation, and mistakes such as crossover and confusion are prone to occur on the label, which seriously affects the safety of clinical blood use. The current disposable plastic blood bags do not have a special sample retention device, so they cannot be safely retained. Studies have shown that most of the blood that is polluted by external bacteria causes bacterial reproduction during blood storage to be within the front-end blood of 5-10ml at the beginning of blood collection. It is very necessary to make necessary improvements to minimize and lower the resulting blood contamination.

Contents of the invention

The technical problem to be solved by the utility model is to overcome the deficiencies of the above-mentioned prior art, and provide a safe storage system with reasonable structure, convenient operation and use, which can ensure the safety of blood collection and reduce blood pollution caused by excessive environment and incomplete skin disinfection during blood collection. Sample blood bag.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a kind of safe blood bag for retaining samples, including closed blood collection needle, anticoagulant whole blood bag, blood collection catheter, characterized in that: closed blood collection needle and anticoagulant whole blood bag A blood sampling bag with a capacity of 10-25 mL is connected between them through a tee and a catheter.

The conduit of the three-way connection sampling blood bag described in the utility model is provided with a frangible plug, and the conduit is a frangible conduit. The conduit is also provided with a stop clip. The top of the blood sampling bag is provided with a sampling joint with a latex cap.

In the utility model, a sampling blood bag is added through a tee on the blood sampling catheter of the plastic blood bag, and the maximum capacity thereof is 25mL. When in use, about 5-10ml of blood in the early stage of blood collection can be discharged into the blood sampling bag, and after blood collection, the blood in the blood sampling bag can be collected into a test tube by a blood collection device for detection. Compared with the prior art, it can perform sampling and separation in the early stage of blood collection. This product is suitable for use under conditions where the external environment is not easy to control, and reduces blood pollution caused by excessive environment and incomplete skin disinfection during blood collection, thus ensuring the safety of clinical blood collection and use. The utility model has reasonable structure, convenient operation and use, and is especially suitable for one-time blood collection and reserved sample detection.

Detailed ways

As can be seen from FIG. 1 , the utility model is a safe blood bag for retaining samples, including a closed blood collection needle 1 , an anticoagulant whole blood bag 7 , and a blood collection catheter 6 . The closed blood collection needle 1 is used for blood collection, and the conventional puncture blood collection can be carried out by breaking off the protective cap 2 thereon. Anticoagulant whole blood bag 7 is used for collecting whole blood. The anticoagulant whole blood bag 7 is provided with a blood transfusion socket 8, a transfer tube 9 and an anticoagulant inlet, etc., which are respectively used for blood transfusion operations to connect blood transfusion sets, transfer whole blood, and add anticoagulant. The blood collection catheter 6 communicates between the closed blood collection needle 1 and the anticoagulated whole blood bag 7 , and the switch is controlled by the switch clip 5 . The anticoagulant whole blood bag 7 can be a single structure or a multiple structure. Their specific structures, connections and functions are basically the same as those of the prior art and will not be described in detail.

The utility model is characterized in that a blood sampling bag 10 with a capacity of 10-25 mL is connected between the closed blood collection needle 1 and the anticoagulant whole blood bag 7 through a tee 3 and a catheter 12 .

The conduit 12 of the tee 3 connected to the sampling blood bag 10 of the utility model is provided with a frangible plug 4, and the conduit 12 is a frangible conduit, when the frangible plug 4 is broken during use, the conduit can be connected. A stop clip 13 is also provided on the conduit 12 . The top of the blood sampling bag 10 is provided with a sampling connector 11 with a latex cap, which is a Y-shaped tee.

When the utility model is in use, the frangible plug 4 in the catheter 12 is broken, and about 5-10 ml of blood in the early stage of blood sampling is discharged into the sampling blood bag 10, then the stop clip 13 on the sampling catheter 12 is closed, and then normal blood sampling begins. After blood collection, the blood in the blood sampling bag 10 can be collected from the sampling joint 11 at the top of the blood sampling bag 10 into a test tube by a blood collection device for testing, and then the blood sampling bag 10 and the blood collection needle are heat-sealed and discarded.

The utility model adopts a special sampling blood bag, which reduces blood pollution caused by excessive environment and incomplete skin disinfection during blood collection, thereby ensuring the safety of clinical blood collection and blood use. The utility model has the advantages of reasonable structure, convenient operation and use, and is especially suitable for one-time blood collection and reserved sample detection under the condition that the external environment is difficult to control.
