[Industrial applications]

 The present invention relates to a rapid blood transfusion device for performing massive blood transfusion in cases of hemorrhagic shock during surgical operation or emergency outpatient, where massive bleeding is predicted, and in other cases.

[0002]

[Prior art]

 At present, when performing general blood transfusion, a blood transfusion set is connected to a blood bag, and blood is transfused by spontaneous fall. When performing blood transfusion by free fall, the transfusion rate decreases as the blood volume in the blood bag decreases, and the transfusion operation becomes difficult over time. This is not a serious problem when the blood transfusion amount is small, but it causes inconvenience when a large blood transfusion is required during large blood vessel surgery such as rupture of an arterial vein or varicose vein or when performing extracorporeal circulation. This is because it is necessary to maintain a minimum circulating blood volume in order to prevent blood loss and, therefore, the lost blood to be infused at a given time. In the above case, a predetermined amount of blood must be injected at a predetermined blood infusion rate, and thus it is not possible to use the usual method or device (transfusion set). Moreover, as the time during transfusion progressed, the filter was blocked due to fibrin in the blood, etc., and the decrease in transfusion rate was promoted. Therefore, some measures had to be taken. In order to solve the above problems, the blood bag is conventionally compressed and rapidly injected. Provide multiple injection (puncture) sites in the body or change the site. In addition, replace the blood bag or transfusion set. Use a blood pump. Etc. were taken. These means require labor to press the blood bag or replace the blood bag or the transfusion set, it takes time and time to secure the blood vessel, and many transfusion sets are attached. The peripheral equipment (suspension stand or fixing table) occupies the operating room, and the blood pump is expensive and not necessarily suitable for rapid blood transfusion.

[0003]

The present invention is capable of injecting a large amount of blood or drug solution in a short time, and can be easily implemented without human labor. In addition, a rapid blood transfusion device that does not occupy a space when performing a surgical operation is provided.

[0004]

[Means for Solving the Problems]

 The present invention is a transfusion device for injecting a large amount of blood in which a blood filter for removing coagulated clots of blood is incorporated in a blood circuit, or a blood transfusion device for injecting a drug solution together with blood. A blood supply line for sending and supplying a drug solution to the blood circuit, and a blood transfusion line for injecting the supplied blood or drug solution into the body, and the blood supply line is a main supply line having a blood filter, It consists of a sub-supply line that is connected to the supply line on the downstream side of the blood filter, and the main supply line is on the upstream side of the blood filter. A blood circuit having a closing / release clamp attached to the tube, and the plurality of tubes eventually branch into a single tube, and the auxiliary supply line is a tip. Ji with a bottle needle attached to the -A blood circuit having a tube and a clamp attached to the tube, wherein the transfusion line is a tube-mounted clamp and a flexible pump tube segment and / or a first drip that can be attached to the blood pump. A blood circuit having a tube, a second drip tube and a connector, characterized in that a tube with a releasable end and a clamp is connected to the upper part of the second drip tube. The rapid transfusion device solved the above problems.

[0005]

[Action]

 Since there are a plurality of tubes for connecting to the container, many blood bags and drug solution containers are connected. Since the blood filter is attached, impurities are removed. Since the tube connected to the container branches downstream from the blood filter, if the filter is blocked, the filter is replaced without replacing the entire blood transfusion device. It has a second drip tube for the blood pressure monitor line and is trapped in the drip tube when air bubbles enter the blood transfusion device. Furthermore, since the tip of the tube connected to the upper part of the drip tube can be opened, air bubbles can be removed and accurate blood pressure can be measured over time. It is equipped with a blood pump tube segment, and forced blood transfusion using a blood pump is also possible.

In addition, the embodiment added as necessary has the following actions. By providing the first drip tube, the drop drip can be performed without using the blood pump. (A drop drip is performed by counting the number of drops.) By attaching a blood heating coil immediately upstream of the connector, the blood is warmed to about the body temperature and injected. By installing the air bubble detector, the risk of sending air bubbles (air) mixed in the blood transfusion device is reduced.

【Example】

 FIG. 1 shows an example of the rapid blood transfusion device 1 of the present invention. This device is a blood transfusion device for injecting a large amount of blood in which a blood filter-2 for removing coagulated clots of blood is incorporated in a blood circuit, or for injecting a drug solution together with blood, and the blood stored in a container 21 It consists of a blood supply line A for supplying and supplying liquid or drug solution to the branch point 8 of the blood circuit, and a blood transfusion line B for injecting the blood or drug solution supplied and supplied to the branch point 8 into the body. . The blood supply line A comprises a main supply line A1 having a blood filter-2 and a sub supply line A2 connected to the main supply line A1 on the downstream side of the blood filter-2. The main supply line A1 has a plurality of tubes 4 to which bottle needles 5 are connected at the tip, and a closing / releasing clamp 6 attached to the plurality of tubes, and the plurality of tubes are provided. Finally becomes a single tube 3 through a branch, and the blood filter-2 is connected to this single tube 3. The present invention is not limited by the form of branching, and can be modified as needed. For example, as shown in FIG. 1, the upstream side of the blood filter-2 may be first divided into two tubes, and one tube may be branched into two tubes, or more tubes may be branched. Alternatively, three or more tubes may be connected to one branch point. The branch itself may be branched or may be branched by means of a connector or the like. The sub-supply line A2 is a blood circuit having a tube 11 having a bottle needle 9 attached to its tip and a clamp 10 attached to the tube 11. If necessary, the auxiliary supply line A2 may be provided with a blood filter in the tube 11 similarly to the main supply line A1, or the provided blood filter-the upstream tube 11 may be provided. It may be composed of a plurality of tubes (with bottle needles and clamps attached). The blood transfusion line B includes a clamp 13 attached to a tube 22, a flexible pump tube segment 14 that can be attached to a blood pump, and / or a first drip tube 12, a second drip tube 15, and a connector-16. As described above, the circuit has a circuit for mixing the blood or the drug solution fed from the main supply line A1 and the sub-supply line A2, or for selectively delivering it to the body. It is a blood circuit. FIG. 1 shows an assembly in which both the first drip barrel 12 and the pump tube segment 14 are incorporated. That is, it is a blood transfusion device in which the first drip tube 12, the clamp 13, the pump tube segment 14, the second drip tube 15, and the connector 16 are connected by the tube 22 in this order from the upstream side. The first drip cylinder 12 is for adjusting the blood transfusion speed by counting the number of drops by a normal drop-type drip when the blood pump is not used, and in the case where the blood pump is not used at all. If so, the pump tube segment 14 may be removed and only the first drip tube 12 may be used. A tube 17 having a releasable end and having a clamp 20 mounted thereon is connected to an upper portion of the second drip tube 15. The second drip tube 15 serves as an air trap when air (air bubbles) is mixed, and a tube 17 having an open end is connected to the upper part of the drip tube. -Can be used as a line. If a three-way stopcock or a side-injection pipe with a cap 18 is attached to the tube 17, it can be used for removing air bubbles. The connector 16 disposed at the most downstream end of the rapid blood transfusion device 1 of the present invention is a luer type so that it can be connected to an injection needle (indwelling needle), a blood vessel catheter, other conduits, etc. It is a lock type or the like, and a three-way stopcock, a side injection pipe 19 or the like may be attached if necessary. If necessary, a bubble detector can be attached to the rapid blood transfusion device 1, or a heating coil for raising the temperature of blood to near body temperature can be incorporated immediately upstream of the connector-16.

The rapid blood transfusion device of the present invention is implemented as follows. In the main supply line A1, a plurality of tubes 4 each having a bottle needle 5 are connected to a container 21 (a blood bag or a drug solution container) in a quantity required for transfusion. When the clamp 6 that is closed is opened, blood and chemicals (hereinafter referred to as blood) flow into the blood circuit. Since there are a plurality of branch tubes 4, a large amount of blood or drug solution can be delivered at one time, and the labor required for exchanging the blood bag or drug solution container can be saved. The blood and the like that have flowed in pass through the blood filter-2 and are filtered, so that blood aggregates and impurities such as fibrin are removed. Even on the downstream side of the blood filter-2, since the auxiliary supply line A2 having the tube 4 with a bottle needle that can be connected to the container 21 is connected, when the blood filter-2 is blocked, the blood transfusion device It is possible to replace only the blood filter-2 without replacing the whole 1. Next, the inflowing blood or the like passes through the first drip cylinder 12 (where the clamp 13 is mounted on the downstream side) and / or the pump segment tube 14. Since the pump tube segment 14 is provided, forced blood transfusion or infusion with a speed controlled by using a blood pump is possible, and when it is not necessary, the first drip tube 12 is used to provide a drop-type transfusion. It is also possible to perform infusion. Further, blood or the like flows into the second drip tube 15, but even if air bubbles are mixed in the blood transfusion device, it can be trapped in the second drip tube 15 and connected to the tube above the drip tube. Bubbles (air) can be easily removed because the tip of 17 can be opened, and if this tube 17 is used as a blood pressure monitor line, accurate blood pressure can be measured over time. Finally, blood or the like is injected into the body through the connector-16, the venous needle, and the blood vessel catheter. Further, as an option, by attaching a blood heating coil immediately upstream of the connector 16 of the blood transfusion device 1, blood or the like can be heated to a body temperature and injected. Furthermore, by installing a bubble detector, the risk of delivering blood mixed in the blood transfusion device is reduced.
