Description
Technical field
This utility model relates to medicine instrument technical field, particularly relates to a kind of transfusion device.
Background technology
Transfusion device is medical device conventional in patient process.Existing transfusion device generally comprises intravenous needle, drips kettle, connects intravenous needle and drip the infusion tube of kettle, be connected the bottle plug puncture unit of a kettle and medicine bottle.For the ease of in infusion process, medical personnel observe transfusion speed, ensure to input in patient body by medicinal liquid safely and effectively in infusion process, generally need arrange dropping liquid finder as dripped kettle in transfusion device.Drip kettle in traditional transfusion device, generally comprising cylindrical or longitudinal section be that kidney ellipsoid drips kettle body, and drip kettle body top and be provided with the feed liquor dropper stretched in a kettle body, bottom is provided with liquid outlet.Do not pull out syringe needle in time when infusion-completed, air can enter in patient body through liquid outlet, can bring larger injury, even life danger to patient body.
Chinese patent 201320642048.3 discloses a kind of transfusion with safety device and drips kettle, comprise and drip kettle, dropper and liquid outlet, described liquid outlet is positioned at the bottom of dripping kettle, a floating plug is provided with above described liquid outlet, the cylindrical shape of floating plug, have gap between floating plug and the inwall dripping kettle, the bottom of floating plug is provided with one deck diaphragm seal, and the top of floating plug is provided with symmetrical horizontal bumping post.When this patent solves infusion-completed preferably and do not pull out syringe needle in time, air can enter the problem in patient body through liquid outlet.But due to the cylindrical shape of described floating plug, experiment finds, after medicinal liquid enters and drips kettle there is the phenomenon of not floating in floating plug sometimes.This drips after kettle because medicinal liquid enters, and drip pressure in kettle and be greater than pressure below liquid outlet, and medicinal liquid buoyancy is difficult to overcome above-mentioned pressure reduction and floated by floating plug, impact transfusion is normally carried out.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of transfusion device, and this transfusion system structure is simple, use safety, and when can avoid infusion-completed and not pull out syringe needle in time, air can enter the problem in patient body through liquid outlet.
The technical scheme that this utility model provides is: a kind of transfusion device, comprise intravenous needle, drip kettle, infusion tube one and bottle plug puncture unit, described intravenous needle is connected by infusion tube one with a kettle, described kettle is connected with bottle plug puncture unit, described bottle plug puncture unit comprises bottle cork needle, the infusion tube two be connected with bottle cork needle, described infusion tube two is provided with flow regulator; Described kettle comprises and drips a kettle body, drips a kettle body upper part and be provided with to stretch into and drip the intrinsic feed liquor dropper of kettle, drip kettle body bottom portion and be provided with liquid outlet, a floating plug is provided with above described liquid outlet, floating plug is the rounding mesa-shaped that upper bottom surface is greater than bottom surface, gap is had between floating plug and the inwall dripping kettle body, the bottom of floating plug is provided with one deck diaphragm seal, and the top of floating plug is provided with limit body, and limit body is connected with a kettle body.
Above-mentioned floating plug top has the folding edge being parallel to floating plug end face.
One deck diaphragm seal is provided with bottom described floating plug.
This utility model is owing to adopting said structure, during use, being inserted by the bottle cork needle of bottle plug puncture unit treats in infusion bottle, medicinal liquid drips in kettle body from the instillation of feed liquor dropper, because floating plug is the rounding mesa-shaped that upper bottom surface is greater than bottom surface, add the medicinal liquid buoyancy face of upward direction, the medicinal liquid be collected at bottom feed tube can easily by floating plug jack-up.This utility model not only structure is simple, and the effect of floating plug jack-up and closed liquid outlet when can better realize infusing, and ensure that the safety of transfusion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See Fig. 1, this utility model comprises intravenous needle 16, protective sleeve 4, liquid medicine filter 17, flow regulator 11, drips kettle 7, infusion tube 15 and bottle plug puncture unit, described intravenous needle 16 is connected by infusion tube 15 with a kettle 7, described kettle 7 is connected with bottle plug puncture unit, described bottle plug puncture unit comprises bottle cork needle 2(bottle cork needle can overcoat protective sleeve 1), the infusion tube 5 that is connected with bottle cork needle 2, bottle cork needle 2 can establish air inlet device 3; Described kettle 7 comprises and drips a kettle body 8, drips kettle body 8 top and be provided with the feed liquor dropper 6 stretching into and drip in kettle body 8, drip bottom kettle body 8 and be provided with liquid outlet 14, a floating plug 10 is provided with above described liquid outlet 14, floating plug 10 is greater than the rounding mesa-shaped of bottom surface in upper bottom surface, gap is had between floating plug 10 and the inwall dripping kettle body 8, the bottom of floating plug 10 is provided with one deck diaphragm seal 13, and the top of floating plug 10 is provided with limit body 9, and limit body 9 is connected with a kettle body 8.
Above-mentioned floating plug 10 top have be parallel to floating plug end face folding along 12, to increase the acting surface of medicinal liquid buoyancy, so that more easily jack-up floating plug 10.
When this utility model uses, the bottle cork needle of bottle plug puncture unit is inserted and treats in infusion bottle.During transfusion, medicinal liquid drips in kettle body, along with the increase of the medicinal liquid be collected at bottom a kettle by floating plug jack-up from the instillation of feed liquor dropper.When transfusion completes, the medicinal liquid face of dripping bottom kettle declines, and infusion port is closed thereupon declining by floating plug.This utility model not only structure is simple, and the effect of floating plug jack-up and closed liquid outlet when can better realize infusing, and ensure that the safety of transfusion.
