Description

A kind of controller for transfusion device
Technical field
This utility model relates to transfusion system safety control technology field, particularly relates to a kind of controller for transfusion device.
Background technology
Transfusion has another name called has an intravenous drip or hangs water, is the large bolus injection liquid inputted by intravenous drip in body.In the infusion bottle that injection is packaged in glass or plastics or bag, not containing antiseptic or antibacterial.Injection medication is direct, and fast, the multiplex treatment in major disease and recovery, output and the use amount of China's injection are huge, and annual also in growth in reaction.
Drip speed by transfusion device adjustment when injection uses, continue and stably enter vein, with supplementary body fluid, electrolyte or provide nutrient substance.The process of transfusion is veryer long, families of patients or medical personnel are generally needed to monitor, in order to avoid gas enters human body by tube for transfusion after liquid is totally lost, easily damage patient, serious is even dead, in addition, the flow of transfusion device adopts roller clip to carry out manual adjustment control usually, Flow-rate adjustment is accurate not, and roller clip easily produces and slides and change the flow set in the process used, use have more constant.
Utility model content
The technical problem that this utility model mainly solves is to provide a kind of controller for transfusion device, the flow of accurate adjustment transfusion device, and injection drips off rear automatic closedown tube for transfusion, improves safety.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: provide a kind of controller for transfusion device, for the flow-control of tube for transfusion, comprise: base back plate, curved baffle, arc pallet, liquid level sensor, controller and miniature electric expansion link, described curved baffle is symmetricly set on the both sides of base back plate respectively, described arc pallet is arranged on the below of curved baffle, tube for transfusion is fixedly installed between curved baffle and arc pallet, described arc pallet is symmetricly set on the both sides of base back plate, described liquid level sensor is arranged in base back plate, described liquid level sensor between curved baffle and arc pallet and its induction end extend to tube for transfusion, the outfan of described liquid level sensor is connected with controller, the outfan of described controller is connected with miniature electric expansion link, described miniature electric expansion link is arranged on the below of arc pallet and is positioned at the side of tube for transfusion, described controller for transfusion device also comprises a block arc, described block arc corresponds to the opposite side that miniature electric expansion link is arranged on tube for transfusion.
In this utility model preferred embodiment, the top of described base back plate is provided with a hanging hole.
In this utility model preferred embodiment, described liquid level sensor is contactless liquid level sensor.
The beneficial effects of the utility model are: a kind of controller for transfusion device that this utility model is pointed out, utilize the pore size between block arc and miniature electric expansion link to adjust the flow of tube for transfusion, precision is high, injection drips off rear liquid level of perfusion tube and declines, controller controls miniature electric expansion link and extends to tube for transfusion and cut out completely after receiving the liquid level decline information that liquid level sensor sends, avoid air to flow into human body, improve the safety used.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in this utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of controller for transfusion device one of this utility model preferred embodiment.
Detailed description of the invention
Be clearly and completely described to the technical scheme in this utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Refer to Fig. 1, this utility model embodiment comprises:
A kind of controller for transfusion device, for the flow-control of tube for transfusion, comprise: base back plate 1, curved baffle 2, arc pallet 3, liquid level sensor 4, controller 5 and miniature electric expansion link 6, described curved baffle 2 is symmetricly set on the both sides of base back plate 1 respectively, described arc pallet 3 is arranged on the below of curved baffle 2, tube for transfusion is fixedly installed between curved baffle 3 and arc pallet 2, the handling that the breach of curved baffle 3 intermediate formation is convenient to tube for transfusion are fixed, described arc pallet 2 is symmetricly set on the both sides of base back plate 1, described liquid level sensor 4 is arranged in base back plate 1, described liquid level sensor 4 between curved baffle 2 and arc pallet 3 and its induction end extend to tube for transfusion, the outfan of described liquid level sensor 4 is connected to input level change signal with controller 5, the outfan of described controller 5 is connected with miniature electric expansion link 6, stretch to control it, described miniature electric expansion link 6 is arranged on the below of arc pallet 2 and is positioned at the side of tube for transfusion, described controller for transfusion device also comprises a block arc 7, described block arc 7 corresponds to the opposite side that miniature electric expansion link 6 is arranged on tube for transfusion, space between block arc 7 and miniature electric expansion link 6 is for tube for transfusion of arranging, by the flow regulating the size in space to control tube for transfusion, regulate precision high and be not subject to the external world and rock and change.
The top that described a kind of controller for transfusion device needs to be hung on transfusion outpatient uses, and the top of described base back plate 1 is provided with a hanging hole 11, convenient and outside link up with etc. with the use of, the side hanging over tube for transfusion is fixed it.
Further, described liquid level sensor 4 is contactless liquid level sensor, and the change of liquid level can be detected in the outside being covered in tube for transfusion, can recycle, and avoids producing the injection of tube for transfusion inside polluting, and safety is high.
In sum, a kind of controller for transfusion device that this utility model is pointed out, achieve the flow-control to tube for transfusion, precision is high, good stability, and injection completes the closedown to tube for transfusion after dripping off in tube for transfusion, improves the safety of transfusion.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize this utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
