According to the infusion set drip tube provided by the utility model, the controlled-flow channel is formed in the drip tube, and the movable floating valve plug is arranged in the controlled flow channel, so that the liquid outlet of the drip tube can be enclosed automatically through the floating valve plug when infusion is completed; moreover, enclosing can be released automatically during replacement of an infusion bottle; the infusion set drip tube is simple in structure, and is convenient to use; and most importantly, the safety of a patient can be guaranteed.
Description
Technical field
This utility model relates to medical instruments field, especially, relates to a kind of safe transfusion system dropper.
Background technology
Existing infusion set dropper comprises the body that is provided with inlet and liquid outlet, and liquid enters body from inlet, directly drips from liquid outlet again.The infusion set dropper of this structure does not have the self-closed effect, when medicinal liquid has flowed needs replacing infusion bottle soon, has hidden danger.If the injection inlet of transfusion device is at the vein negative pressure section of human body, the air that enters so infusion pipeline will be inhaled in the vein blood vessel, cause damage to human body; If injection inlet is at the vein malleation section of human body, the downcomer herb liquid that connects entry needle constantly reduces, until during the medicinal liquid pressure balance in human vein blood pressure and the transfusion device downcomer, medicinal liquid stops to flow, but when patient limb moves, thereby will cause the blood pressure change to break pressure balance, blood in the vein can flow to the conduit of tube for transfusion, if untimely processing, just easily form thrombosis, block injection needle, behind the infusion bottle that more renews, also can't change dressings and continue injection, then again inject new human body and need again change needle tubing.
The utility model content
This utility model purpose is to provide a kind of safe transfusion system dropper, needs the replacing infusion bottle to solve when medicinal liquid flow soon, the technical problem that present infusion set dropper can't self-closed.
For achieving the above object, according to an aspect of the present utility model, provide a kind of infusion set dropper, comprised dropper, be arranged on flow control passage and the interior mobilizable unsteady valve plug of flow control passage in the dropper.
Further, dropper is Split type structure, comprises upper shell and is connected to the lower house of upper shell, and the top of upper shell is provided with inlet, and the bottom of lower house is provided with liquid outlet.
Further, the flow control channel setting and communicates with liquid outlet in lower house.
Further, the flow control passage is the cylindrical shell of both ends open, is provided with the slotted eye that communicates with the inner chamber of dropper around the flow control passage.
Further, the flow control passage comprises banking stop, and banking stop is installed in the top of flow control passage.
Further, banking stop is provided with through hole, and through hole is communicated with the inner chamber of dropper with the inner chamber of flow control passage.
Further, unsteady valve plug is hollow-core construction or the solid construction made for light material.
The utlity model has following beneficial effect: infusion set dropper of the present utility model arranges the flow control passage in dropper, movable unsteady valve plug is set in the flow control passage, so that when transfusion finishes, unsteady valve plug can the self-closed dropper liquid outlet, can when changing infusion bottle, automatically remove sealing again, simple in structure and easy to use, the most important thing is to guarantee patient's safety.
Except purpose described above, feature and advantage, this utility model also has other purpose, feature and advantage.The below is described in further detail this utility model with reference to figure.
Description of drawings
The accompanying drawing that consists of the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining this utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is that the infusion set dropper of this utility model preferred embodiment has the structural representation under the liquid condition in dropper; And
Fig. 2 is infusion set dropper structural representation under the no liquid state in dropper of this utility model preferred embodiment.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that this utility model can be defined by the claims and cover is implemented.
Referring to Fig. 1 and Fig. 2, preferred embodiment of the present utility model provides a kind of infusion set dropper, comprises dropper 10, is arranged on flow control passage 20 and flow control passage 20 interior mobilizable unsteady valve plugs 30 in the dropper 10.
Dropper 10 is Split type structure, comprises upper shell 11 and is connected to the lower house 12 of upper shell 11, and when lower house 12 was connected on the upper shell 11, upper shell 11 was salable with the junction of lower house 12.In the present embodiment, upper shell 11 and lower house 12 are glued together; In other embodiment, upper shell 11 and lower house 12 weld together.The top of upper shell 11 is provided with inlet 13, and the bottom of lower house 12 is provided with liquid outlet 14.Liquid enters in the dropper 10 from inlet 13, then flows out from liquid outlet 14.
The valve plug 30 that floats is positioned at flow control passage 20 movably, and unsteady valve plug 30 can seal liquid outlet 14 when contacting with liquid outlet 14.Preferably, unsteady valve plug 30 is spherical in shape.In other embodiments, the valve plug 30 that floats can also be other shape, such as taper, rhombus.The valve plug 30 that floats can be that hollow-core construction also can be the solid construction that light material is made, so that the valve plug 30 that floats can float over liquid surface.The size of unsteady valve plug 30 volumes slips out flow control passage 20 greater than the size of liquid outlet 14 and slotted eye volume to prevent float trap plug 30.In the present embodiment, the size of through hole 211 is less than the size of the valve plug 30 that floats, and banking stop 21 can stop the valve plug 30 emersion flow control passages 20 that float.
When being full of liquid in the dropper 10, the valve plug 30 that floats is positioned at the upper end of flow control passage 20, and constrictor 21 is kept out the valve plug 30 that floats.The liquid level of the liquid in the dropper 10 descends gradually, and when gradually being lower than the top of flow control passage 20, the valve plug 30 that floats floats over liquid surface, descends along with the decline of liquid levels.Flowed or liquid when having flowed when being about in the dropper 10, the valve plug 30 that floats drops on the liquid outlet 14, automatically with liquid outlet 14 sealings, prevents that air from entering into the blood flow of human body or human body to the conduit of tube for transfusion.Change infusion bottle this moment, and liquid splashes in the dropper 10, and when reaching a certain height, thus the valve plug 30 that floats will be automatically along with the rising of dropper 10 liquid levels breaks away from liquid outlet 14, so that liquid can flow out from liquid outlet 14.
Infusion set dropper of the present utility model is at the dropper 10 interior flow control passages 20 that arrange, at the flow control passage 20 interior unsteady valve plugs 30 that activity is set, so that when transfusion finishes, the liquid outlet 14 that valve plug 30 can self-closed dropper 10 floats, can when changing infusion bottle, automatically remove sealing again, simple in structure and easy to use, the most important thing is to guarantee patient's safety.
The above is preferred embodiment of the present utility model only, is not limited to this utility model, and for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
