Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: a medical automatic closing type transfusion device, which comprises a transfusion bottle 8 and a buffer tube 2, wherein the outlet of the transfusion bottle 8 is provided with a connector 7, an air inlet pipe 1 is arranged at one side of the connector 7, an installation pipe 17 is arranged at one end of the air inlet pipe 1 far away from the connector 7, filter screens 16 are symmetrically arranged at the top and the bottom of the inner side of the installation pipe 17, an activated carbon layer 19 is arranged at the middle position of the inner side of the installation pipe 17, a drip tube 6 is arranged at the bottom end of the connector 7, an infusion tube 5 is arranged at the bottom end of the drip tube 6, and one end of the transfusion tube 5 far away from the drip tube 6 is provided with a needle 3, the interior of the drip tube 6 is movably provided with a movable ring 13, the middle position of the inner side of the movable ring 13 is uniformly provided with a connecting rod 10, and one end of the connecting rod 10 far away from the movable ring 13 is provided with a connecting seat 14, a mounting rod 11 is arranged at the central position of the bottom of the connecting seat 14, and a suction cup 12 is arranged at the bottom end of the mounting rod 11.

In this embodiment, four sets of limiting strips 9 are uniformly arranged on the inner side of the drip tube 6, and four sets of limiting grooves 15 matched with the limiting strips 9 are uniformly arranged on the outer side of the movable ring 13, which is helpful for improving the lifting stability of the movable ring 13 in the drip tube 6 and ensuring that the sucker 12 is always positioned right above the outlet of the drip tube 6.

In this embodiment, the connecting seat 14 is a cone structure, and the thickness of the top of the inner side of the movable ring 13 gradually increases toward the bottom, which is helpful for the liquid medicine in the drip tube 6 to rapidly pass through the hole between the movable ring 13 and the connecting seat 14.

In this embodiment, a sealing cover 18 is hinged to one side of the top of the mounting tube 17, and a sealing ring matched with the mounting tube 17 is arranged on the inner side of the sealing cover 18, which helps to prevent external dust from entering the mounting tube 17 during the connection process of the device and an infusion bottle.

In this embodiment, an adjusting switch 4 is arranged at one end of the outer side of the infusion tube 5 close to the needle 3, and a double-faced adhesive layer is arranged at one side of the adjusting switch 4, so that the adjusting switch 4 can be conveniently stuck and fixed at a proper position and the infusion speed inside the adjusting switch 5 can be controlled.
