Embodiment Construction

[0044] Attached below figure 1 -6 is explained as follows:

[0045] The needle-free intravenous infusion device relates to a structural feature that a rotary plunger valve device 3 or more than one rotary plunger valve device 2 and 3 are installed on the infusion bottle body 1 .

[0046] The rotary plunger valve devices 2 and 3 have the same structure, the device 2 is used for adding medicine or pressurizing and ventilating, and the device 3 is used for infusion.

[0047] Taking the rotary plunger valve device 3 as an example, the structure of the rotary plunger valve device is further described in detail, the plunger sleeve 8 and the plunger 9 are assembled,

[0048] The plunger sleeve 8 is provided with one or more inner positioning steps 12 for assembling with the corresponding outer positioning steps 19 provided on the plunger 9. After the plunger sleeve 8 and the plunger 9 are assembled, it becomes a so-called Rotate the plunger valve type device, and then set one or mo...

Abstract

The intravenous transfusion device without needle has structure comprising one or two rotary plunger valve type units mounted to the transfusion bottle. The rotary plunger valve type unit consists of plunger sleeve and plunger assembled together, the plunger sleeve has one or several inner positioning steps to match the outer positioning steps in the plunger, and the plunger has other one or several outer positioning steps to match the inner positioning steps in the mouth of the transfusion bottle. The present invention has the positive effects of stable and reliable transfusion, no air pollution, no contaminant from cracked bottle plug matter, convenient pressurizing, ventilation and medicine addition and no pricking of skin.

Description

technical field [0001] The needle-free intravenous infusion device relates to a device for introducing medicinal liquid into the body by means of medical infusion injection. Background technique [0002] At present, there is no relevant technical literature to publish and report a similar technical solution, and there is no product sales or clinical use; the closest prior art to the present invention is common infusion tubes and infusion bottles with needles. The present invention is different in structure from common infusion bottle tubes, technically refitting the common infusion bottle mouth with a rotary plunger valve type bottle stopper, which is a technical invention for this type of medical device. Contents of the invention [0003] The purpose of the present invention is to provide a common infusion bottle with one or more rotary plunger valve stoppers, and use matching infusion tubes instead of traditional infusion needles during infusion to prevent liquid gas pol...
