Description
Technical field
This utility model relates to field of medical device, rotates liquid changing device in particular to one.
Background technology
Transfusion is almost everyone therapeutic process of living through, and transfusion has another name called has an intravenous drip or hangs water.It is heavy dose (single administration is at more than the 100ml) injection inputted by intravenous drip in body.In the transfusion bottle that injection is packaged in glass or plastics or Pig, not containing antiseptic or antibacterial.Drip speed by transfusion device adjustment during use, continue and stably enter vein, with supplementary body fluid, electrolyte or provide nutrient substance or other materials.
When being in a bad way, general doctor can hold many bottles of (or many bags) injection to patient, and injection one bottle graft one bottle is injected vein when infusing by patient, and last bottle injection needs to change one bottle of injection and injects after having injected.
In prior art when performing said process, by artificial, tube for transfusion is pulled up in the rear transfusion bottle of insertion by medical personnel from previous transfusion bottle, generally, medical personnel can monitor each patient, when the injection that medical personnel notice in some transfusion bottles will be finished, can shift to an earlier date a period of time goes to this patient, prepares to change dressings; Medical personnel busy and not to be noted time, patient oneself also can call medical personnel to change dressings; In some cases, medical personnel and patient all not to be noted in transfusion bottle injection be finished and maybe will be finished, now tube for transfusion is still inserted in patient, when in tube for transfusion, injection remains little, its pressure can be less than blood in human body in hydraulic coupling, and backflow of blood can be caused to enter tube for transfusion, and this situation is very dangerous, if dealt carefully with not in time, very serious consequence can be caused.
Although above-mentioned situation is comparatively rare, once occur, consequence is serious, therefore of the prior artly changes liquid method and change liquid equipment effect poor, there is greater risk.
Chinese patent CN201320310008.9, discloses a kind of transfusion device, and many tube for transfusions are simply coupled together by a threeway by it, and high material consumption, manifold volume are large, and practicality is poor, can not realize automatic control; Chinese patent CN201320073717.X discloses a kind of novel transfusion device, and its structure is also fairly simple, and volume is comparatively large, can not realize automatic control equally.
