Specific embodiment

Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

Specific embodiment of the present utility model is described below in conjunction with attached drawing.

Fig. 1-3 shows a kind of perfusion tube of anti-return blood, including perfusion tube 1, and the perfusion tube 1 is followed successively by from top to bottom Needle for inserting bottle 2, drip tube 3, flow regulator 4 are provided with sealed tube 6, the envelope between the needle for inserting bottle 2 and the drip tube 3 The perfusion tube that stopped pipe 6 connects the needle for inserting bottle 2 protrudes into the upper end of the sealed tube, and the sealed tube 6 connects the drip tube 3 Perfusion tube protrudes into the bottom end of the sealed tube 6, and there are gaps with the bottom of the sealed tube 6；4 lower section of flow regulator Equipped with obstruction pipe 5, the side of the obstruction pipe 5 is equipped with fixing pipe 51, the fixed block 52 being set in fixing pipe 51 and passes through rubber The magnetic ball 53 that tree lace is connect with the fixed block 52；The lower end of the obstruction pipe 5 is equipped with magnet ring button 7.

Further, the sealed tube 6 connects the perfusion tube of the drip tube 3 in inverted L shape.Inverted L shape makes liquid or sky Gas is not easy to flow to sealed tube from drip tube.

Further, the fixed block 52 is nested in the fixing pipe 51, and movable in the fixing pipe 51.It pulls Fixed block can pull the magnetic ball of connection fixing block, can also allow magnetic ball without being inverted perfusion tube in the state of initially Not occluding infusion pipe.

Further, the magnet ring button 7 is divided to for the two circular arc buttons 71 in left and right, be provided in the circular arc button 71 with it is described defeated The circular arc magnet ring 72 of liquid pipe fitting, two described 71 one end of circular arc button are hinged, and the other end is connected by retaining ring 73.Magnet ring button can It disassembles, facilitates the recycling of magnet ring button.

Further, the lower end of the magnet ring button 7 is equipped with the second fixed block 54, and the magnetic ball 53 is far from the connection fixation One end of block 52 connects second fixed block 54.Second fixed block connects magnetic ball by rubber covered wire, can inhale in circular arc magnet ring When attached magnetic ball, it is oriented to for the sinking of magnetic ball.

The working principle or workflow that the utility model generates: before infusion, it is first inverted obstruction pipe 5, so that magnetic ball 53 Perfusion tube 1 is left, while utilizing siphonage, so that liquid enters obstruction pipe 5, work of the magnetic ball 53 by buoyancy by sealed tube 6 With floating, infusion is normally carried out.When infusion soon terminates, the liquid level in sealed tube 6 is defeated lower than connecting with drip tube 3 Liquid pipe stops being infused to drip tube 3, and forms fluid-tight.After the remaining liquid of perfusion tube is finished, magnetic ball 53 is by circular arc magnet ring 72 magnetic adsorptive power effect, occluding infusion pipe.It is acted on by the fluid-tight of 53 occluding infusion pipe of magnetic ball and sealed tube, anti-hemostasis Liquid or gas backstreaming.

It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard To belong to the protection scope of the utility model.
