Abstract

(57) [Summary] [Purpose] To prevent air from flowing into the tube downstream of the drip tube even when the infusion bottle of the drip set is empty. [Constitution] In an infusion set consisting of a venous needle, a clamp, an infusion tube, etc., a check ball, which is lighter than the infusion solution, is placed in the infusion tube. A check ball that descends together with the infusion surface in the drip tube closes the tube inlet to prevent air from flowing into the tube. [Effect] The replacement of the infusion bottle has become extremely easy, and it is no longer necessary for the nurse to constantly monitor the infusion state. Further, even if the infusion bottle becomes empty, the backflow of blood to the infusion set is prevented.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention provides an infusion set consisting of a bottle needle, a drip tube, a clamp, a vein needle, etc. The present invention relates to an infusion set with an infusion stop function, in which a check ball is placed in a drip tube.

[0002]

[Prior art]

  Insert the bottle needle into the suspended infusion bottle, fill the drip tube with half of the infusion solution, and insert it into the human body. The clamp adjusts the rate of infusion into the implanted venous needle. Infusion tube replacement for infusion bottles It must be done when there is infusion left inside.

[0003]

[Problems to be solved by the device]

  An infusion set consisting of a drip tube and a clamp, etc. The infusion surface of the drip tube descends and moves into the tube that reaches the clamp. in this way When the infusion surface drops inside the tube and air enters the tube, a new infusion bottle is opened. Even if you put it on, you cannot drip it as it is. It is necessary to remove the air that has entered the tube This has made the drip work on-site due to lack of manpower more troublesome. In addition, the infusion bottle is empty If the above condition is removed, blood will flow back from the venous needle and blood will flow into the tube. Was likely to solidify. Therefore, an infusion solution consisting of a drip tube, a clamp, and a venous needle. The principle is that the nurse always monitors on the side when the drip is infused in the set. This was not possible at the site, and it often caused inflow of air into the tube and backflow of blood.

[0004]

[Means for Solving the Problems]

  A bottle needle to be inserted under the suspended infusion bottle, a drip tube for checking the drip state, An infusion set consisting of a clamp and a venous needle at its tip Place a check ball floating on. Has a specific gravity slightly lower than that of infusion This check ball has a material such as silicone or has a sterilized surface. ing.

[0005]

[Action]

  Insert the bottle needle from the bottom of the infusion bottle, fill the drip tube with half of the infusion solution, and clamp. Loosen and let the infusion solution flow out from the venous needle, remove the air from the tube in the route, and then Close the clamp. Insert an air needle into a specified place and puncture a blood vessel of the human body with a venous needle. To do. Start the infusion while watching the drip state while loosening the clamp.   The infusion solution is regularly dropped from the infusion bottle into the drip tube to keep the infusion surface inside the drip tube constant. One (Fig. 1). The check ball in the drip tube floats in the infusion solution as shown in the figure. It is far from the tube inlet at the bottom of the drip tube.

[0006]   When the infusion bottle becomes empty, the infusion surface of the drip tube descends, and the checkboard Also descends and closes the lower tube inlet (Fig. 2). At this time , The infusion solution remains in the drip tube and the inflow of air into the tube is completely blocked. However, in the case of a conventional drip tube without a check ball, the infusion surface would drop further and To descend.   Set a new infusion bottle, press the drip tube, and start dropping the infusion solution again in the drip tube. Then, the infusion surface in the drip tube rises and the check ball is lifted from the tube inlet. It Then, new infusion is supplied to the blood vessel.

【Example】

． Hanging infusion bottle 1 Bottle needle inserted in the lower part, and drip tube 2 for checking the drip state And a clamp 3 and a venous needle 4 at the tip of the clamp 3 A check ball 5 that floats on the infusion solution is placed in 2. Ratio of infusion (drip fluid, blood transfusion, etc.) This check ball 5, which has a specific gravity slightly smaller than its weight, is made of a material such as silicone. It has a wood or sterilized surface. Check ball 5 is limited to spherical The point is that it moves up and down together with the infusion surface in the drip tube 2 and descends to the tube. It suffices that the tube inlet 6 is always closed when the tube inlet 6 is reached.   In addition to disposing the check ball 5 in the drip tube 2, a tube is provided on the upstream side of the drip tube 2. Alternatively, the check balls 5 may be arranged in this cylinder.   A part of the check ball 5 floating in the infusion solution of the drip tube 2 is slightly transfused. It is preferable that the specific gravity is such that it is exposed on the surface.

[Effect of device]

  In short, the present invention is a drip state with a bottle needle inserted in the lower part of the suspended infusion bottle 1 Infusion set consisting of a drip tube 2 for confirming the above, a clamp 3 and a venous needle 4 at its tip. In this case, since the check ball 5 that floats on the infusion solution is placed in the drip tube 2, Air is prevented from entering the path (tube etc.) below 2 and blood is infused. It is possible to prevent the backflow into the flow path. Therefore, it is necessary for the nurse to constantly monitor the IV drip. Instead, the infusion bottle can be replaced safely and reliably.
