Abstract
A kind of new disposable transfusion system, including flow-stopping clip, minim pipette and flow regulator, restraining position ring block is set in the minim pipette, limit sleeve is installed below the stop collar, floating plug is provided between the stop collar and limit sleeve, the maximum width of the floating plug is greater than the minimum range between two jacket wall of limit sleeve, and for limit sleeve in coniform, the floating plug is ingot type or ball-type.
Description
Technical field
The present invention relates to a kind of new disposable transfusion systems.
Background technique
At present in medicine and hygiene fields, disposable infusion set is widely used, venous transfusion is carried out to patient, have quiet
Arteries and veins dosing techniques are convenient, improve curative effect, positive effect that is disposable, preventing cross-infection.However, common disposable
Infusion apparatus is not due to having automatic-closing mechanism, when infusion-completed fails to pull out needle in time, will lead to blood backflow or pipe
It is intravenous to advance to patient for air in road, can cause blood clotting embolism, threat to life when serious.Simultaneously because such original
Cause, patient and medical staff must pay close attention to whether infusion is completed at the moment, to pull out needle in time, bring tightly to patient and medical staff
The pressure opened.
Summary of the invention
The purpose of the present invention is overcoming problems of the prior art, the new of one kind health easy to use, safe is provided
Type disposable transfusion device.
In order to achieve the above object, the technical solution of the invention is as follows: a kind of new disposable transfusion system, including fluid stopping
Folder, minim pipette and flow regulator, it is characterised in that: restraining position ring block, the lower section peace of the stop collar are set in the minim pipette
Equipped with limit sleeve, floating plug is provided between the stop collar and limit sleeve, the maximum width of the floating plug is greater than two sets of limit sleeve
Minimum range between wall, for limit sleeve in coniform, the floating plug is ingot type or ball-type.
The present invention compared with the existing technology has the advantage that
1, the present invention is blocked with circular cone floating plug plug-in type, has that block binding face longer, plays good plugging action, while by
It is close, coniform in length in binding face length, fitting, as long as in the case where rocking of reverse property does not occur in infusion apparatus, generally all
The safe effect preferably blocked is played in the drift that floating plug will not occur.
2, infusion apparatus down-off adjuster need to only be barred up, slightly be squeezed under minim pipette with hand in infusion-completed by the present invention
Portion can again be floated up floating plug due to the effect of pressure, open flow regulator, can carry out more bottles of infusions,
It is compact-sized, it is not required to complicated exterior components.
3, the configuration of the present invention is simple, be easy production, that clinical manipulation is easy to drain inner air tube, safety is good.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure: flow-stopping clip 1, minim pipette 2, flow regulator 3, stop collar 4, limit sleeve 5, floating plug 6.
Specific embodiment
Below in conjunction with Detailed description of the invention and specific embodiment, the present invention is described in further detail:
Referring to Fig. 1, a kind of new disposable transfusion system, including flow-stopping clip 1, minim pipette 2 and flow regulator 3, the minim pipette 2
Interior setting restraining position ring block 4, the lower section of the stop collar 4 is equipped with coniform limit sleeve 5, between the stop collar 4 and limit sleeve 5
It is provided with the floating plug 6 of ingot type or ball-type, the maximum width of the floating plug 6 is greater than the minimum range between 5 liang of jacket walls of limit sleeve.
Use process of the invention are as follows: be connected to bottle inserting needle of transfusion system with medical fluid, medical fluid is by conduit stream in minim pipette 2
In, then by the gap between limit sleeve 5 and floating plug 6, flow into 2 lower end of minim pipette, be full of to lower end medical fluid, drain both under air,
And medical fluid is made, in 4 or more stop collar, vein pin puncture vein blood vessel can first to be used by normal infusion program, at this time medical fluid in height
Patient's body will be entered by conduit, liquid medicine filter and intravenous infusion needle.When infusion, floating plug 6 under the buoyancy of medical fluid,
Always it suspends, keeps gap with limit sleeve 5, medical fluid will be flowed down unimpededly, realize infusion.Stop collar 4 is used to limit floating plug 6 floating
The height risen in order to avoid floating plug 6 rises too high with liquid level, and influences observation drop.
Infusion nearly finishes, and floating plug 6 gradually falls with medical fluid liquid level, until being bonded completely with limit sleeve 5, and finally closes
It closes, medical fluid stops flowing, then air will not enter 2 lower end of minim pipette and infusion pipeline.Replace other one if necessary at this time
Another bottle liquid medicine and bottle inserting needle of transfusion system need to only be connected followed by infusion, shut flow regulator 3 by bottle, squeeze dropping liquid with hand
2 lower end of pipe, floating plug 6 is floated, and medical fluid is made to enter minim pipette 2, and drains 2 both under air of minim pipette, so that it may is infused again again.
It is fully completed to infusion, after floating plug 6 is bonded closing with limit sleeve 5, the flow-stopping clip 1 of 2 upper end of minim pipette is pressed from both sides extremely, then
2 lower end flow regulator 3 of minim pipette is pushed into shut at 2 lower end liquid outlet of minim pipette, infusion apparatus is removed, cuts off fluid stopping with scissors
3 lower end conduit of 1 upper end conduit and flow regulator is pressed from both sides, at this time remaining medical fluid in minim pipette 2, just in closed minim pipette 2
Realize that medical fluid keeps sample.
