Description

  The present invention relates to a rapid infusion device in which a priming process is performed before a liquid is transferred.

  For example, when a liquid such as whole blood or a blood product is transferred to a patient, air should be prevented from being mixed into the blood vessel for safety. Therefore, before transferring the liquid, the liquid circuit of the apparatus is filled with the priming liquid to remove the air in the liquid circuit. The priming liquid is stored in a reservoir bag before being introduced into the liquid circuit of the device and mixed with other drugs in the reservoir bag. Conventionally, as a method for supplying the priming liquid into the reservoir bag, a method in which the priming liquid is suspended at the upper stage of the drip stand and the reservoir bag is suspended at the lower stage (Patent Document 1). As a result, the priming liquid is supplied to the reservoir bag by the height difference.

  The priming liquid needs to be controlled so that the amount supplied to the reservoir bag is an appropriate amount. That is, when there is too little priming liquid, the liquid circuit of the apparatus cannot be filled and air remains. On the other hand, when there is too much priming solution, the concentration of other drugs in the reservoir bag is too thin, so that adjustment takes time and the priming solution introduced into the patient's body increases. Therefore, in the conventional supply method using the difference in height, the supply amount is controlled by monitoring the supply amount of the priming liquid and stopping the supply by clamping the liquid circuit when the operator determines that the supply amount is appropriate. It was.

  However, in the above-described method, when the operator misses the timing to stop the supply of the priming liquid, the priming liquid is supplied in excess of an appropriate amount, and finally the entire amount is stored in the reservoir bag. Therefore, the operator needs to pay close attention to the supply amount of the priming liquid, and cannot perform other operations while monitoring the supply amount of the priming liquid. As described above, it has been difficult to supply an appropriate amount of the priming solution to the reservoir bag without deteriorating the work efficiency in the medical field.

  An object of the present invention is to provide a rapid infusion device capable of easily adjusting the supply amount of a priming solution to a reservoir bag without monitoring the supply amount. .

  The present invention relates to a rapid infusion device that is equipped with a liquid circuit having a reservoir bag for storing a liquid to be transferred, and that heats and transfers the liquid that passes through the liquid circuit and that stores the priming liquid.

At least one of the bag support part and the reservoir bag support part is supported by the stand part so as to be movable in the vertical direction, and the priming liquid in the priming liquid storage bag is transferred between the priming liquid storage bag support part and the reservoir bag support part. The difference in height can be used to supply into an empty reservoir bag.

  When the liquid level of the priming liquid remaining in the priming liquid storage bag and the liquid level of the priming liquid stored in the reservoir bag are the same level, the priming liquid is automatically supplied from the priming liquid storage bag to the reservoir bag. Stop. And according to this rapid infusion device, by changing the vertical position of the priming liquid storage bag support part and the reservoir bag support part, the height difference between the priming liquid storage bag and the reservoir bag can be freely adjusted, The height difference between the priming solution storage bag and the reservoir bag can be adjusted so that the supply amount of the priming solution is appropriate. As a result, the supply amount of the priming liquid to the reservoir bag can be easily adjusted without monitoring the supply amount.

  The priming liquid storage bag is suspended from the priming liquid storage bag support part, the reservoir bag is suspended from the reservoir bag support part, and the priming liquid storage bag support part is disposed below the reservoir bag support part. It is preferable that By disposing the priming liquid storage bag support part below the reservoir bag support part, at least the suspending position of the priming liquid storage bag can be set to a position lower than the suspension position of the reservoir bag. As a result, it becomes easy to prevent the entire amount of the priming liquid in the priming liquid storage bag from being supplied into the reservoir bag, and it becomes easy to supply an appropriate amount of the priming liquid.

  In addition, it is preferable that the stand portion is provided with a position display portion that indicates a height difference between the priming liquid storage bag support portion and the reservoir bag support portion. Since the height difference between the priming liquid storage bag and the reservoir bag can be visually confirmed, fine adjustment of the supply amount of the priming liquid is facilitated.

A hole is provided in the upper part of the priming liquid storage bag 4B, and the reservoir bag 4 is suspended from the lower movable hanger part 48B by hooking this hole on the hook 48g.

  A scale 49 is engraved on the support 47a. This scale 49 is engraved at an interval of 1 cm, for example, and the number of scales 49 engraved between the lower end of the slider part 48a of the upper movable hanger part 48A and the upper end of the slider part 48a of the lower movable hanger part 48B. By reading, it is possible to grasp the relative vertical position (height difference) between the reservoir bag 4 and the priming liquid storage bag 4B. The scale 49 functions as a position display unit.

  Subsequently, an operation of supplying a certain amount of the priming liquid PL from the priming liquid storage bag 4B to the reservoir bag 4 will be described with reference to FIGS.

  FIG. 6A shows a state before the priming liquid PL is supplied from the priming liquid storage bag 4B to the reservoir bag 4. FIG. The reservoir bag 4 is in an empty state in which neither the liquid L nor the priming liquid PL is stored. On the other hand, the priming liquid storage bag 4B is filled with the priming liquid PL. A tube is connected to the lower end of the priming liquid storage bag 4B, and this tube is connected to the lower part of the reservoir bag 4 to form a priming liquid supply line 8. The priming liquid supply line 8 can be opened and closed by a priming liquid clamp 9 disposed in the middle of the priming liquid supply line 8.

  First, as shown in FIG. 7, the knob screw 48b of the upper movable hanger part 48A is appropriately adjusted while reading the scale 49 of the column part 47a, and the upper movable hanger part 48A is fixed at a predetermined height position. Next, the knob screw 48f of the lower movable hanger portion 48B is appropriately adjusted while reading the scale 49 of the support column portion 47a, and the lower movable hanger portion 48B is fixed at a predetermined height position. By this operation, the relative vertical position (height difference) between the reservoir bag 4 and the priming liquid storage bag 4B is determined. In addition, according to the capacity | capacitance of the reservoir bag 4 and the priming liquid storage bag 4B to be used, the standard of a height difference is decided beforehand, and according to this standard, the position of the upper stage movable hanger part 48A and the lower stage movable hanger part 48B is finely adjusted.

At the initial stage of supply, the liquid level of the priming liquid PL in the priming liquid storage bag 4B is higher than the liquid level of the priming liquid PL stored in the reservoir bag 4. Accordingly, the priming liquid PL moves from the priming liquid storage bag 4B to the reservoir bag 4 due to natural fall. When the movement of the priming liquid PL from the priming liquid storage bag 4B to the reservoir bag 4 progresses and the liquid level in the priming liquid storage bag 4B and the liquid level in the reservoir bag 4 become the same, the movement of the priming liquid PL Stops automatically. That is, if the height difference between the reservoir bag 4 and the priming solution storage bag 4B is adjusted so that the supply amount of the priming solution PL becomes a desired amount, the supply amount is monitored after the priming solution clamp 9 is opened. Even if not, the priming liquid PL is not excessively supplied.

  In addition, if the capacity | capacitances of the priming liquid storage bag 4B and the reservoir bag 4 to be used differ, the quantity of the priming liquid PL supplied to the reservoir bag 4 will differ before the liquid level becomes the same height. Accordingly, it is necessary to finely adjust the height difference according to the priming liquid storage bag 4B and the reservoir bag 4 to be used, but in the present embodiment, the fine adjustment is very easy. Even if it is desired to store more (or less) priming liquid PL than usual in the medical field, the supply amount of the priming liquid PL can be visually checked by finely adjusting the height difference while reading the scale 49. Can be easily adjusted.

  As described above, according to the rapid infusion device 1 according to the present embodiment, the height of the priming solution storage bag 4B and the reservoir bag 4 is changed by changing the vertical relative positions of the lower movable hanger portion 48B and the upper movable hanger portion 48A. The height difference between the priming liquid storage bag 4B and the reservoir bag 4 can be adjusted so that the difference can be adjusted freely and the supply amount of the priming liquid PL is appropriate. As a result, the supply amount of the priming liquid PL to the reservoir bag 4 can be easily adjusted without monitoring the supply amount.

  In this embodiment, the priming liquid storage bag 4B is suspended from the lower movable hanger part 48B, the reservoir bag 4 is suspended from the upper movable hanger part 48A, and the lower movable hanger part 48B is movable upward. It is arranged below the hanger part 48A. Accordingly, at least the suspending position of the priming liquid storage bag 4B can be set lower than the suspending position of the reservoir bag 4. As a result, it becomes easy to prevent the entire amount of the priming liquid PL in the priming liquid storage bag 4B from being supplied into the reservoir bag 4, and it becomes easy to supply an appropriate amount of the priming liquid PL.

  The stand portion 47 is provided with a scale (position display portion) 49 that indicates a difference in level between the lower movable hanger portion 48B and the upper movable hanger portion 48A, and the height between the priming liquid storage bag 4B and the reservoir bag 4 is increased. Since the difference can be visually confirmed, fine adjustment of the supply amount of the priming liquid PL is facilitated.

  As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited only to said embodiment. For example, in the above-described embodiment, the priming liquid storage bag and the reservoir bag are supported by being suspended. However, the priming liquid storage bag and the reservoir bag may be supported and supported from below. Further, the position display unit is not limited to the scales that are engraved at regular intervals, but is marked at two predetermined positions, for example, a height position for the reservoir bag and a height position for the priming liquid storage bag. It is also possible to imprint. In this case, since it is not necessary to read the scale, the position where the storage bag is fixed can be confirmed at a glance, and the supply amount can be adjusted more easily. In the above embodiment, both the upper movable hanger part 48A and the lower movable hanger part 48B are movable in the vertical direction, but either the upper movable hanger part 48A or the lower movable hanger part 48B is vertically movable. It may be movable in the direction.
