The novel anti-reverse flow precise infusion apparatus is simple in structure and novel in design, the anti-reverse flow device is added in a traditional infusion apparatus, the anti-reverse flow device can freely transform closed states according to the pressure of the two ends of an infusion tube, so that the anti-reverse flow effect of the infusion tube is achieved.
Description
Technical field:
The present invention relates to technical field of medical instruments, be specifically related to a kind of novel counterflow-preventing precision infusion set.
Background technology:
In prior art, transfusion device is made up of dropping funnel, speed regulator, conduit and needle tubing usually, and the liquid in medicine bottle or medicated bag enters dropping funnel, is directly delivered to vein blood vessel by conduit.
In infusion process, get rid of the gas in medicinal liquid, anti-return blood phenomenon occurs most important to infusion safety.If deal with improperly just in case occur that air enters the conduit of dropping funnel bottom, unexpected blood back phenomenon will be there is.Blood back phenomenon not only can cause conduit cannot continue transfusion due to air embolism, blood coagulation even can be caused to become clot and damage human body, and the serious problems such as nosocomial infection, septicemia, in treatment clinical course, how to process this problem and bring adverse consequences to be a stubborn problem always.
And in prior art, for the processing method of the problems referred to above, be all often the mode of remedying concentrating on medical personnel, as being wound around conduit aerofluxus fast, pulling out the methods such as transfusion needle is exhausted and process.These operations often bother very much, not only need veteran medical personnel to operate, and easily occur pulling the thunder bolt generations such as unexpected.Thus, not only waste medicinal liquid but also easily cause nosocomial infection, and namely use such method to process, also be only solve the problem that can again infuse, the thrombotic risk such as venous thrombosis, other blood vessel embolisms caused for blood coagulation clot and the risk problem of the grievous injury such as nosocomial infection, septicemia, remain and cannot tackle the problem at its root.
Summary of the invention:
The object of this invention is to provide a kind of novel counterflow-preventing precision infusion set, its structure is simple, novel in design, in traditional transfusion device, add anti-backflow device, anti-backflow device freely can convert closure state according to the pressure at tube for transfusion two ends, realizes the counterflow-preventing of tube for transfusion.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it comprises anti-backflow device, upper connector, lower connector, quarter circular arc block piece, moving rotary axle, counterflow-preventing dividing plate; The upper end of described anti-backflow device is provided with connector, and the lower end of anti-backflow device is provided with lower connector; Be provided with quarter circular arc block piece on the right side of the interior lower end of described anti-backflow device, the centre of anti-backflow device is provided with moving rotary axle, moving rotary axle is connected with counterflow-preventing dividing plate.
The upper end of described anti-backflow device is connected to transfusion and drips kettle, and the upper end that kettle is dripped in transfusion is connected to infusion bottle; The lower end of described anti-backflow device is connected with transfusion speed regulator, and the lower end of transfusion speed regulator is connected with transfusion needle connection component and the interspersed pin of transfusion.
Described anti-backflow device is hollow sphere structure, and quarter circular arc block piece and anti-backflow device are integral type structure.
Beneficial effect of the present invention: its structure is simple, novel in design, in traditional transfusion device, add anti-backflow device, anti-backflow device freely can convert closure state according to the pressure at tube for transfusion two ends, realizes the counterflow-preventing of tube for transfusion.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Fig. 2 is anti-backflow device structural representation in the present invention.
Reference numeral: transfusion device body 1, transfusion drip kettle 2, anti-backflow device 3, transfusion speed regulator 4, transfusion needle connection component 5, transfusion interspersed pin 6, upper connector 7, lower connector 8, quarter circular arc block piece 9, moving rotary axle 10, counterflow-preventing dividing plate 11.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with the drawings and the specific embodiments, the present invention is further elaborated.Should be appreciated that detailed description of the invention described herein only in order to explain the present invention, be not intended to limit the present invention.
Referring to Fig. 1, this detailed description of the invention by the following technical solutions: it comprises anti-backflow device 3, upper connector 7, lower connector 8, quarter circular arc block piece 9, moving rotary axle 10, counterflow-preventing dividing plate 11; The upper end of described anti-backflow device 3 is provided with connector 7, and the lower end of anti-backflow device 3 is provided with lower connector 8; Be provided with quarter circular arc block piece 9 on the right side of the interior lower end of described anti-backflow device 3, the centre of anti-backflow device 3 is provided with moving rotary axle 10, moving rotary axle 10 is connected with counterflow-preventing dividing plate 11.
The upper end of described anti-backflow device 3 is connected to transfusion and drips kettle 2, and the upper end that kettle 2 is dripped in transfusion is connected to infusion bottle; The lower end of described anti-backflow device 3 is connected with transfusion speed regulator 4, and the lower end of transfusion speed regulator 4 is connected with transfusion needle connection component 5 and the interspersed pin 6 of transfusion.
Described anti-backflow device 3 is hollow sphere structure, and quarter circular arc block piece 9 and anti-backflow device 3 are integral type structure.
The operation principle of this detailed description of the invention: when carrying out normal infusion, because infusion bottle is hung in height, the pressure effect that the counterflow-preventing dividing plate 11 in anti-backflow device 3 is subject to upper end is rotated, and makes upper and lower connection tube conducting; When blood backflow appears in tube for transfusion, the pressure of the interspersed pin end of transfusion is greater than the pressure of infusion bottle end, and counterflow-preventing dividing plate 11 turns round, and upper connector 7 and the lower connector 8 of anti-backflow device 3 is cut off, realizes anti-return.
Beneficial effect of the present invention: its structure is simple, novel in design, in traditional transfusion device, add anti-backflow device, anti-backflow device freely can convert closure state according to the pressure at tube for transfusion two ends, realizes the counterflow-preventing of tube for transfusion.
The above, only in order to technical scheme of the present invention to be described and unrestricted, other amendment that those of ordinary skill in the art make technical scheme of the present invention or equivalently to replace, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of right of the present invention.
