Description

Technical Field

[0001] The utility model relates to the field of medical devices, and in particular to an anti-restart checkpoint and an infusion device for intercepting an infusion tube. Background Art

[0002] A common infusion method is to put the liquid in a bottle or hang the liquid in an infusion bag at a high place, and use gravity to make the liquid flow into the vein through the infusion tube. A switch needs to be configured on the infusion tube of the infusion bag to realize the infusion work of the infusion tube.

[0003] However, since the infusion bag is a disposable medical device, it is not allowed to be used again after use and needs to be scrapped. Figure 4 In the ordinary switch card shown, the operator operates the switch card by pressing the snap-fit ​​surface 101 with the thumb, supporting the switch card with the index finger, snapping it with force, and snapping the snap-fit ​​surface 101 into the hook 102 to achieve the closing action of the switch card. The first protrusion 103 and the second protrusion 104 on the switch card squeeze the infusion tube, thereby achieving the interception of the infusion tube. However, in the switch card in the prior art, the operator only needs to push the hook 102 upwards, and the switch card can be restored to the open state under the elasticity of its own material.

[0004] The above design allows the switch card to be opened and closed repeatedly. When the infusion is finished, the switch card cannot completely close the pipeline to prevent the switch card from being opened again, which creates a safety hazard for the reuse of the infusion bag. Utility Model Content

[0005] Therefore, the technical problem to be solved by the present invention is how to solve the problem in the prior art that the switch card for the infusion bag can be repeatedly opened and closed, thereby causing the potential safety hazard of the infusion bag being reused.
