Detailed Description

The infusion drip cup of the utility model can be made of the following materials, and is not limited to the following materials, for example: plastic, silicone, PVC, and the like.

Fig. 1 is a side structure view of an infusion drip cup according to an embodiment of the present invention; and refer to fig. 2.

The utility model provides a transfusion drip cup for install on the infusion pipe. The embodiment of the utility model provides an include: the device comprises an elastic and closed cavity 1, a floating plate 3, a connecting rod 4 and a piston 5; the cavity 1 is the main structure of the transfusion drip cup. The float 3 is a generally horizontal circular float.

A cylindrical liquid storage pipe 2 is arranged at the bottom end of the accommodating cavity 1; the floating plate 3 is positioned in the cavity 1, and the piston 5 is positioned in the liquid storage pipe 2; the bottom of the floating plate 3 is connected with the piston 5 through the connecting rod 4; in general, the connecting rod is a plastic rod and is integrally extruded with the floating plate; the connecting rod is connected to the central position of the floating plate and is perpendicular to the floating plate.

The liquid storage pipe is generally thin in pipe diameter and also plays a role in lifting the liquid level.

A magnetic ring 7 is arranged at the bottom of the liquid storage pipe 2, and a liquid outlet 70 is arranged on the magnetic ring 7; drain port 70 is typically connected to drain 20 for gravity transfer of the drip chamber contents to the body.

A magnet 6 attracted with the magnetic ring 7 is arranged in the piston 5; the piston 5 slides up and down in the liquid storage tube 2 under the action of the floating plate to open or close the liquid outlet 70.

In the infusion drip cup of this embodiment, the accommodating cavity 1 and the liquid storage tube 2 are both generally transparent elastic structures.

The utility model discloses in the use, guarantee that the kickboard is holding the intracavity free floating, and the kickboard does not touch the bottom surface that holds the chamber and can normal use.

When infusion is started, the containing cavity and the liquid storage pipe are pinched after the infusion needle is inserted into the infusion bottle, so that the floating plate is far away from the bottom of the containing cavity, liquid can rapidly enter the containing cavity, and the floating plate can smoothly float. Due to the action of the connecting rod, only the liquid storage pipe outside the connecting rod needs to be pinched, and the floating plate can be naturally far away from the bottom of the accommodating cavity, so that the operation is very convenient.

When the transfusion is about to end, the magnet on the piston automatically approaches the magnetic ring under the action of magnetic force, so that the piston seals the liquid discharge port, and the function of blocking the transfusion liquid is started. The technical problems of the prior art that the floating ball is blocked and overturned due to the rapid liquid drop are solved.

In the infusion drip cup of the present embodiment, the piston 5 is tightly sleeved in the liquid storage tube 2; a plurality of flow guide holes 50 are formed in the piston 3 in the vertical direction; the flow guide holes 50 ensure that the piston does not block the reservoir 2 in a suspended state.

The plurality of flow guide holes 50 correspond to the magnetic ring 7 in the vertical direction. Thereby ensuring that the magnetic ring can effectively block the diversion hole 50 when the piston contacts with the magnetic ring.

Further, the magnet 6 is located at a central position between the diversion holes 50, and the position of the magnet 6 corresponds to the position of the liquid discharge port 70 in the vertical direction.

The utility model discloses in, because the piston is closely established by the liquid storage pipe cover, after magnet and magnetic ring attracted the laminating, the position can not take place the dislocation, and also easily lifts up the piston under the exogenic action, is convenient for repeatedly carry out the infusion operation.

In the infusion drip cup of the present embodiment, generally, the overall height of the connecting rod 4 and the piston 5 is greater than or equal to the height of the liquid storage tube 2, so as to ensure that the piston can effectively block the liquid outlet.
