Abstract

The utility model discloses a transfusion device capable of changing infusion liquid automatically, which comprises transfusion pipe inserting needles, a dripping pot, a dripping speed regulator, the transfusion pipe and a needle head, wherein the quantity of the inserting needles is two or more than two; the inserting needles are connected into a whole by air pipes; an air passage in the next inserting needle and a fluid passage in the previous inserting needle are communicated by the air pipes among the inserting needles; an air inlet pipe which is provided with a microfilter is connected with a first inserting needle; a ball-shaped floating plug is arranged in the dripping pot; the diameter of the floating plug is 4 mm to 5 mm. The infusion liquid change of the utility model dispenses with manual operation, and thus, the utility model reduces the workload of medical staffs, lightens the mental load of patients and nursing staffs, and simultaneously, decreases the visitor flow quantity of a ward so that the ward is quiet and clean.

Description

From moving the liquid transfusion device
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of transfusion device.
Background technology
Existing transfusion device, no matter be transfusion devices common or functions such as band prompting and safety, when need defeated many bottles (bag), after one bottle of (bag) liquid is totally lost, change another bottle (bag) liquid by medical personnel, the defeated medical personnel of patient will come and go and run 2-5 time, not only workload is big, and influence other patient's rest, if it is untimely to change liquid, cause air admission liquid-transport pipe-line or backflow of blood, increased the difficulty that continues transfusion work, in order to prevent the generation of this situation, patient or entourage must note the variation of liquid at any time, have increased its stress.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming and the liquid that changes that provides need not manually-operated from moving the liquid transfusion device.
The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions: of the present utility model from moving the liquid transfusion device, comprise the tube for transfusion contact pin, drip kettle, drip fast actuator, tube for transfusion and syringe needle, wherein contact pin is a plurality of, be chained together by trachea between each contact pin, the air flue of next contact pin inside is communicated with by the trachea between the contact pin with the fluid passage of a last contact pin inside, and the air inlet pipe of band microfilter links to each other with first contact pin.Dripping in the kettle has a spherical floating plug, and the diameter of floating plug is the 4-5 millimeter.
The above-mentioned liquid transfusion device of moving certainly, contact pin is more than 2 or 2.
The above-mentioned liquid transfusion device of moving certainly, contact pin is 3.
Compared with prior art, this utility model can be provided with the contact pin more than 2 according to actual needs, be chained together by trachea between each contact pin, the air flue of next contact pin inside is communicated with by the trachea between the contact pin with the fluid passage of a last contact pin inside, and the air inlet pipe of band microfilter links to each other with first contact pin.During use, the contact pin backward is inserted and is treated accordingly in the loading bottle (bag), be convenient to the following tube for transfusion full of liquid of contact pin, after first bottle of (bag) medicinal liquid is totally lost, air just can enter the air flue in next contact pin by the trachea between first contact pin and the next contact pin, second bottle of (bag) medicinal liquid begins to import human body, by that analogy, realizes from the function of moving liquid; Spherical floating plug floats on the liquid level that drips in the kettle, and after liquid was totally lost, it can clog the outlet of dripping kettle, thereby avoids the air admission tube for transfusion, plays the safeguard protection effect.This utility model has reduced medical personnel's workload, has alleviated patient and entourage's mental burden, makes that simultaneously the flow of the people in ward is reduced, and makes the ward become quieter and cleaning.
The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Labelling among the figure: 1, A contact pin; 2, B contact pin; 3, C contact pin; 4, A trachea; 5, B trachea; 6, microfilter; 7, air inlet pipe; 8, drip kettle; 9, floating plug; 10, A medicine bottle (bag); 11, B medicine bottle (bag); 12, C medicine bottle (bag).
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to the specific embodiment of moving the liquid transfusion device certainly, structure, feature and the effect thereof that the utility model proposes with 3 contact pins, describe in detail as after.
From moving the liquid transfusion device, comprise the tube for transfusion contact pin, drip kettle, drip fast actuator, tube for transfusion and syringe needle, wherein be chained together by A trachea 4 between A contact pin 1 and the B contact pin 2, the fluid passage of A contact pin 1 inside is communicated with by A trachea 4 with the air flue of B contact pin 2 inside, be chained together by B trachea 5 between B contact pin 2 and the C contact pin 3, the fluid passage of B contact pin 2 inside is communicated with by B trachea 5 with the air flue of C contact pin 3 inside, and the air inlet pipe 7 of band microfilter 6 links to each other with the air flue of A contact pin 1 inside; Dripping in the kettle 8 has a spherical floating plug 9, and the diameter of floating plug 9 is 4.5 millimeters.
During use, the contact pin backward is inserted and is treated accordingly in the loading bottle (bag), be that C contact pin 3 inserts C medicine bottle (bag) 12, B contact pin 2 inserts in B medicine bottle (bag) 11, the A contact pin 1 insertion A medicine bottle (bag) 10, tube for transfusion full of liquid under the contact pin, after A medicine bottle (bag) 10 medicinal liquids were totally lost, air just can enter the air flue of B contact pin 2 inside by A trachea 4, and the medicinal liquid in the B medicine bottle (bag) 11 begins to import human body, by that analogy, realize from the function of moving liquid; When in dripping kettle 8 medicinal liquid being arranged, spherical floating plug 9 floats on the medicinal liquid face, and after medicinal liquid was totally lost, it can fall and clog the outlet of dripping kettle 8, thereby avoids the air admission tube for transfusion, plays the safeguard protection effect.
The above, it only is preferred embodiment of the present utility model, be not that this utility model is done any pro forma restriction, any technical solutions of the utility model content that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
