Abstract
An air-in prevention type infusion set belongs to medical device filed, mainly consisting of a puncture needle, a connection pipe, a dropping pot, a filtering device and a joint. A safe valve which is made of polymer material or stainless steel metal material is arranged in the dropping pot. When the utility model is used, if the liquid level is lower than the safe value, the safe valve is closed automatically, thus the air is prevented from wrongly getting into the vein vascular of human body, the transfusion treatment safe is ensured.
Description
One, technical field
This utility model belongs to medical instruments field, and a kind of air that prevents that specially refers to transfusion usefulness is strayed into the formula transfusion device.
Two, background technology
Hospital adopts common disposable infusion set always when providing infusion treatment for the patient.Because this kind transfusion device is simple in structure, no corresponding protection device in clinical use, when usually changing bottle because of maloperation or transfusion, directly enters in the catheter of transfusion system air, brings great inconvenience to clinical manipulation.Particularly the interior air of conduit enters the human vein blood vessel with liquid sometimes, causes air embolism, has a strong impact on patient's body health.Even more serious is that when this type of transfusion device directly was connected with central venous catheter, the air admission central vein can not be absorbed by the body, and causes air embolism, will injure patient's life.
In view of above reason, wish that can develop a kind of air that prevents is strayed into the formula transfusion device, prevent that air is strayed into the human vein blood vessel in the infusion process, ensure the safety of infusion treatment.
Three, summary of the invention
The technical problems to be solved in the utility model is exactly in order to prevent that in the infusion treatment process air is strayed into the human vein blood vessel, avoids the patient to cause unnecessary damages when infusion treatment.Ensure the safety of infusion treatment.
The technical scheme that this utility model is taked is: a kind of air that prevents is strayed into the formula transfusion device, mainly is made up of puncture needle, connecting pipe, filter, a kettle and joint.It is characterized in that, drip the kettle liquid feeding end, liquid outlet is bonding with connecting pipe respectively.A relief valve is installed in dripping in the kettle of being adopted additional, and when liquid level was lower than safety value in dripping kettle, relief valve cut out automatically, prevents that air is strayed in the tube for transfusion.
Described automatic blow off valve can adopt medical macromolecular materials to make, and also can adopt the stainless steel metal material to make.Safety valve structure is: valve, spool all adopt identical cone to cooperate, and the spool upper end also has cylinder or cone floating drum, are evenly equipped with on the floating drum that to be not less than Φ 1mm liquid-through hole some.
In the use, liquid enters when dripping kettle, and when liquid level was higher than safety value, the relief valve spool floated automatically, and valve open carries out normal infusion; When liquid level was lower than safety value, the relief valve spool is valve-off under action of gravity, prevented that air is strayed into liquid-transport pipe-line, ensured the safety of transfusion.
The beneficial effects of the utility model are, it compared with prior art, this transfusion device has prevented from maloperation or has changed in bottle infusion process air to be strayed into liquid-transport pipe-line and to enter in the human vein, avoids patient's unnecessary damages when infusion treatment, guarantees the safety of transfusion.
Four, description of drawings
Fig. 1 is profile of the present utility model and annexation figure
Fig. 2 drips the structural representation of kettle relief valve for this utility model.
Five, the specific embodiment:
With reference to Fig. 1, wherein 1 is the transfusion device puncture needle, and it is connected with infusion bottle or transfusion bag; 2 is tube for transfusion, respectively with the puncture needle lower end, to drip kettle 3 upper ends bonding; 4 is tube for transfusion, bonding with the liquid feeding end that drips kettle 3 lower ends and filter 6 respectively, has installed flow regulator 5 on the tube for transfusion 4 additional; 7 is tube for transfusion, bonding with filter 6 liquid outlets and 6:100 outer cone joint 8 upper ends respectively; Outer cone joint 8 is connected with venoclysis needle etc.
With reference to Fig. 2, the kettle body 3 that drips that float-type spool 2 that a pot lid 1, medical macromolecular materials or the stainless steel metal material that a kettle is made by medical macromolecular materials ABS made and medical macromolecular materials PVC make is formed.The spool tapering of its float-type spool 2 is consistent with the valve tapering that drips kettle body 3.
Claims (3)
1. one kind prevents that air is strayed into the formula transfusion device, mainly is made up of puncture needle, connecting pipe, a kettle, filter and joint, it is characterized in that: drip a kettle and be built-in with the relief valve of being made by macromolecular material or stainless steel metal material.
2. be strayed into the formula transfusion device according to the described air that prevents of claim 1, it is characterized in that: relief valve spool, valve all adopt identical cone to cooperate.
3. be strayed into the formula transfusion device according to the described air that prevents of claim 1, it is characterized in that: relief valve spool upper end has cylinder or cone floating drum, is evenly equipped with on the floating drum that to be not less than Φ 1mm liquid-through hole some.
