Abstract
This utility model relates to a kind of transfusion device.This utility model automatic stop type transfusion device comprises infusing looks pipe, wherein said transfusion is looked and is provided with diaphragm seal in the pipe, diaphragm seal is provided with circular hole, be provided with connecting line in the circular hole, the upper end of connecting line is connected with the floating plug with the circular hole cooperating, and the lower end of connecting line is connected with the pendant that can be stuck in the diaphragm seal lower surface.Advantage of the present utility model and good effect are: owing to be provided with the sealing device of being made up of diaphragm seal and floating plug, pendant etc. in pipe is looked in transfusion, when the transfusion bottle medicinal liquid flows to end, can stop the air in the transfusion device to continue to flow, thereby making transfusion look liquid level in the pipe, to remain on certain position motionless, so, change dressings even without nurse call in time, medicinal liquid was failed given the misery that increases patient; Simultaneously, when changing dressings,, needn't have an acupuncture treatment again, further alleviate patient's misery, and can not cause the waste of transfusion device, be beneficial to saving, environmental protection as long as medicinal liquid to be changed is directly received on the tube for transfusion.
Description
Technical field
This utility model relates to a kind of transfusion device, particularly a kind of automatic stop type transfusion device.
Background technology
Existing transfusion device structure comprises tube for transfusion and the syringe needle that is connected with tube for transfusion, is provided with transfusion and looks pipe on tube for transfusion.When giving patient infusion, look the fast situation of dripping that intraluminal fluid drips and suitably regulate transfusion speed by observing transfusion by patient oneself or entourage, after medicinal liquid is totally lost, transfusion is looked medicinal liquid in the pipe when beginning to move down, need patient or entourage in time nurse call change dressings or pull out pin, failed as medicinal liquid, the common practice is that more the transducer set transfusion device penetrates patient's intravenous once more, not only cause waste, also increased patient's misery, especially concerning the long or heavier patient of the course of disease, this traditional transfusion device to cover end more outstanding, waste very greatly, misery can be stood seldom or never.In addition, the patient is because uncomfortable, and entourage also labor is stranded and can't bear, and falls asleep when the transfusion of being everlasting finishes, or has neglected because of other reasons, and nurse call is not changed dressings in time, and the too much or medicinal liquid of patient's blood back was failed etc., also caused certain misery.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of medicinal liquid in a bottle liquid medicine is totally lost the back transfusion device can stop, can alleviating patient suffering's automatic stop type transfusion device automatically.
For achieving the above object, this utility model adopts following technical scheme:
This utility model automatic stop type transfusion device, comprising infuses looks pipe, wherein said transfusion is looked and is provided with diaphragm seal in the pipe, described diaphragm seal is provided with circular hole, be provided with connecting line in the described circular hole, the upper end of connecting line is connected with the floating plug with the circular hole cooperating, and the lower end of connecting line is connected with the pendant that can be stuck in the diaphragm seal lower surface.
Wherein said circular hole is arranged on the central authorities of diaphragm seal.
Wherein said circular hole periphery is provided with sealing ring.
Wherein said pendant is formed by being radial equally distributed four ribs.
The advantage and the good effect of automatic stop type transfusion device of the present utility model are: in this utility model, owing in pipe is looked in transfusion, be provided with the sealing device of forming by diaphragm seal and floating plug, pendant etc., when the transfusion bottle medicinal liquid flows to end, can stop the air in the transfusion device to continue to flow, thereby making transfusion look liquid level in the pipe, to remain on certain position motionless, so, both do not made not in time nurse call pull out pin or change dressings, also can not increase patient's misery; Simultaneously, when changing dressings,, needn't have an acupuncture treatment again, further alleviate patient's misery, and can not cause the waste of transfusion device, be beneficial to saving, environmental protection as long as medicinal liquid to be changed is directly received on the tube for transfusion.
Description of drawings
Fig. 1 is the structural representation of this utility model automatic stop type transfusion device when transfusion state;
Fig. 2 is the structural representation of this utility model automatic stop type transfusion device when sealing state;
Fig. 3 is the structure for amplifying sketch map of the diaphragm seal in this utility model.
Among the figure: 1. pipe is looked in transfusion; 2. diaphragm seal; 3. circular hole; 4. connecting line; 5. floating plug; 6. pendant; 7. sealing ring; 8. tube for transfusion.
The specific embodiment
Below in conjunction with accompanying drawing, further describe the specific embodiment of this utility model automatic stop type transfusion device, but be not used for limiting protection domain of the present utility model.
Referring to Fig. 1, Fig. 2.Automatic stop type transfusion device of the present utility model, comprise tube for transfusion 8 and the syringe needle that is connected with tube for transfusion 8, tube for transfusion 8 is provided with transfusion and looks pipe 1, transfusion is looked in the pipe 1 and is provided with diaphragm seal 2, and diaphragm seal 2 central authorities are provided with circular hole 3, are provided with connecting line 4 in the circular hole 3, the upper end of connecting line 4 is connected with the floating plug 5 that can match with circular hole 3, the lower end of connecting line 4 is connected with pendant 6, and this pendant 6 is formed by being radial equally distributed four ribs, and it can be stuck in the lower surface of diaphragm seal 2.In this utility model,, on circular hole 3 peripheries, sealing ring 7 is set in order to increase sealing property.
In this utility model, the structure in pipe 1 is looked in transfusion, other structures, identical as tube for transfusion, syringe needle etc. with existing transfusion device structure, no longer describe in detail.
When automatic stop type transfusion device of the present utility model, normal transfusion state, under the medicinal liquid buoyancy, floating plug 5 is suspended in the medicinal liquid, and pendant 6 is stuck in the lower surface of diaphragm seal 2; When transfusion is fast when finishing, floating plug 5 is looked the decline of pipe 1 inner liquid medicine liquid level along with transfusion and is descended, and when medicinal liquid dropped to diaphragm seal 2 and drops to certain position, floating plug 5 moved down under pendant 6 and the action of gravity of himself and closely cooperates with sealing ring 7 in the circular hole 3.At this moment, do not have air admission because tube for transfusion 8 and transfusion are looked in the pipe 1, be in air-tight state, medicinal liquid just stops automatically, can not continue to move down, and as long as how long no matter good seal crossed, medicinal liquid can not move, and still rests on original rest position.So, use automatic stop type transfusion device of the present utility model, owing to have automatic hold function, both made patient or entourage fall asleep, neglect or left because of thing, can not influence the replacing medicinal liquid.In infusion process, medicinal liquid was failed, so, when changing dressings, only need that medicinal liquid to be changed is directly received tube for transfusion 8 and get final product, need not to give again to suffer from all to have an acupuncture treatment, thereby alleviated patient's misery.
More than be preferred forms of the present utility model, according to the disclosed content of this utility model, some identical, replacement schemes that those of ordinary skill in the art can expect apparently all should fall into the scope that this utility model is protected.
