Abstract
Disclosed is an infusion device capable of preventing blood return which comprises a Murphy infusion tube and an infusion catheter. A floating ball seat arranged inside the Murphy infusion tube is a box body formed by connecting a lower seat box and an upper seat box through grid strips; a floating ball is disposed inside the box body; and the bottom portion of the box body extends out after passing through the lower seat box along a ball seat infusion catheter and passing through the bottom portion of the Murphy infusion tube. By adopting the technical scheme that the floating ball seat arranged inside the Murphy infusion tube is the box body formed by connecting the lower seat box and the upper seat box through the grid strips, the floating ball is disposed inside the box body, and the bottom portion of the box body extends out after passing through the lower seat box along the ball seat infusion catheter and passing through the bottom portion of the Murphy infusion tube, the infusion device overcomes the shortcomings that an existing infusion device needs medical care personnel and accompanying personnel to timely observe liquid inside a bottle, causes trouble to nursing work, and can not prevent blood return and the like when in infusion. The infusion device capable of preventing blood return is adaptable to infusion in various hospitals and various infusion places.
Description
Technical field
This utility model relates to a kind of blood return preventing infusion device.
Background technology
At present, in hospital, generally use disposable intravenous infusion set, by syringe needle, Fei Shi tube for transfusion and conduit are not formed, whether its liquid is totally lost, mainly observe by Fei Shi tube for transfusion not, in case being totally lost, in time do not handle liquid, phenomenon to transfusion catheter internal reflux blood can take place in the needle tubing place of patient skin surface transfusion, as blood coagulation in tube for transfusion, medicinal liquid just can't be imported in the human body, also need medical personnel's contact pin injection elsewhere again, increased patient's misery, and in a single day the air in the pipe enters human vein and can cause thrombosis, entail dangers to human life when serious, need medical care and entourage in time to observe the output state of liquid in the bottle for this reason when infusing, increased nursing intensity to medical personnel.
Summary of the invention
At above-mentioned situation, the purpose of this utility model provides a kind of simple in structure, and is safe and reliable, with low cost, and in time closing pipe line prevents the blood return preventing infusion device that the blood back phenomenon takes place when liquid is totally lost.
For achieving the above object, a kind of blood return preventing infusion device, comprise not Fei Shi tube for transfusion and transfusion catheter, do not dispose the ball float seat in the Fei Shi tube for transfusion, this ball float seat connects into framework by seat of honour frame through a grizzly bar and a following frame, configuration one ball float in the framework, the framework bottom is through postpone a ball seat transfusion catheter and pass not bottom the Fei Shi tube for transfusion and stretch out of a following frame.
For implementation structure optimization, its further step also has:
Grizzly bar is evenly to lay.
Ball float is a hollow ball.
Seat of honour frame is the solid lid.
Seat of honour frame is the reticulate body lid.
This utility model adopts and is not disposing the ball float seat in the Fei Shi tube for transfusion, this ball float seat connects into framework by seat of honour frame through a grizzly bar and a following frame, configuration one ball float in the framework, framework bottom is through postpone a ball seat transfusion catheter and passing bottom the Fei Shi tube for transfusion not and the technical scheme of stretching out of a following frame, overcome existing transfusion device when transfusion, need medical care and entourage in time to observe liquid in the bottle, make troubles, can not prevent defectives such as blood back to nursery work.
The beneficial effect that this utility model is produced compared to existing technology: (1) is adopted the ball float seat is set in Murphy's burette, in the ball float seat ball float is housed, and when medicinal liquid is totally lost, can in time block the transfusion catheter mouth, prevents the blood back phenomenon, and is safe and reliable;
(2) simple and reasonable, with low cost, be convenient to extensive popularization; (3) alleviated medical personnel and entourage's workload greatly.
This utility model is fit to the usefulness of the transfusion in all kinds of hospitals and the place of respectively infusing.
Below in conjunction with drawings and Examples this utility model is described further.
Description of drawings
Fig. 1 is the structural representation of this utility model blood return preventing infusion device.
Fig. 2 is the structural representation of reticulate body lid for the seat of honour frame of this utility model ball float seat.
Structural representation when Fig. 3 infuses for this utility model blood return preventing infusion device.
Fig. 4 is the structural representation after this utility model blood return preventing infusion device transfusion.
Among the figure: 1, Fei Shi tube for transfusion not, 2, transfusion catheter, 3, the ball float seat, 31, seat of honour frame, 32, grizzly bar, 33, a following frame, 34, ball float, 35, the ball seat transfusion catheter.
The specific embodiment
Referring to accompanying drawing 1, a kind of blood return preventing infusion device comprises not Fei Shi tube for transfusion 1 and transfusion catheter 2, do not disposing ball float seat 3 in the Fei Shi tube for transfusion 1, this ball float seat 3 connects into framework by seat of honour frame 31 through a grizzly bar 32 and a following frame 33, and this framework is a cylindrical shape, and grizzly bar 32 is evenly to lay.Configuration one ball float 34 in the framework in order to prevent that ball float 34 emersion frameworks are outer and to be convenient to safeguard that seat of honour frame 31 is made the solid lid, also can be made the reticulate body lid.Ball float 34 is a hollow ball.Framework bottom is through postpone a ball seat transfusion catheter 35 and pass not Fei Shi tube for transfusion 1 bottom and stretch out of a following frame 33.
Shown in accompanying drawing 2, accompanying drawing 3, when this utility model blood return preventing infusion device uses, when this blood return preventing infusion device with after medicine bottle is communicated with, medicinal liquid enters not Fei Shi tube for transfusion 1 through transfusion catheter 2, after medicinal liquid is full of, it is that solid lid or reticulate body lid place stop that ball float 34 floats to the seat of honour frame 31 of framework, and medicinal liquid enters ball seat transfusion catheter 35 through a following frame 33 of framework bottom.When in the medicine bottle during no medicinal liquid, ball float 34 is because action of gravity, along with the medicinal liquid in the Fei Shi tube for transfusion not 1 descends and falls, ball float 34 falls into down seat frame 33 places, the ball seat transfusion catheter that seat frame 33 is postponed is blocked for 35 mouthfuls, blood is stopped in the ball seat transfusion catheter 35, thereby prevents the generation of blood back phenomenon.
