Description
Technical field
This utility model belongs to medical devices, the infusion needle guide tube that particularly transfusion is used.
Background technology
When the liquid in infusion bottle has soon flowed, as closed not in time the switch on transfusion catheter, present transfusion catheter will be inputted air into human body, causes the thrombosis people's death that causes infusing, and this is the problem that long-term puzzlement nurses the sick.So it is all very nervous to transfusion to protect Nursing personnel and the patient of soil, transfusion patient, they not bery feel at ease to have a rest during transfusion for a long time to make it.
Summary of the invention
The purpose of this utility model is to provide a kind of liquid be totally lost after, do not have air and input the safety infusion wire guide into human body, and patient can oneself change the infusion needle guide tube of infusion bottle.
Structure of the present utility model is:
A kind of anti-air admission type safety and conveniently change the transfusion catheter of infusion bottle, comprise flexible catheter 1, one end of flexible catheter 1 be communicated with thrust mouth of infusion bottle 2 get liquid hard tube 3, the other end of flexible catheter 1 is communicated with the transfusion needle 4 that thrusts human body, flexible catheter 1 is provided with liquid flow controller switch 5, it is characterized in that:
Flexible catheter 1 is also provided with the automatic switching system 6 that makes flexible catheter 1 conducting or close; Automatic switching system 6 comprises two conductive contacts 7, switch controller 8 and the flexible catheter motor switch 9 being connected successively, two conductive contacts 7 are to switch controller 8 output switching signals, and switch controller 8 is to the electric energy of flexible catheter motor switch 9 output driving switch actions;
Two conductive contacts 7 of automatic switching system 6 are located in flexible catheter 1, and the output electric wire of two conductive contacts 7 is connected with switch controller 8;
The flexible catheter 1 that flexible catheter 1 position at two conductive contact 7 places and flexible catheter 1 connect between transfusion needle 4 is provided with flexible catheter motor switch 9, flexible catheter motor switch 9 is connected with switch controller 8, flexible catheter motor switch 9 is connected on flexible catheter 1, and flexible catheter 1 is carried out conducting or closed.
Because medicinal liquid in flexible catheter 1 always conducts electricity, while having liquid in flexible catheter 1, two conductive contact 7 conductions, two signals that conductive contact 7 allows flexible catheter motor switch 9 open to switch controller 8 outputs, switch controller 8 is opened normal infusion to flexible catheter motor switch 9 output electric energy by flexible catheter motor switch 9.While there is no liquid in flexible catheter 1, two conductive contacts 7 disconnect non-conductive naturally, two signals that conductive contact 7 allows flexible catheter motor switch 9 close to switch controller 8 outputs, switch controller 8 is to flexible catheter motor switch 9 output electric energy, and automatically allowing flexible catheter motor switch 9 close can not have liquids and gases to pass through flexible catheter motor switch 9.Automatically realize one bottle of transfusion liquid after being totally lost, flexible catheter 1 is closed automatically, prevent that gas from flowing to transfusion needle 4 from flexible catheter 1 and being input among human body again, automatically prevented the insecurity of transfusion, patient is when transfusion, allow and protect the Nursing personnel of soil, transfusion patient and patient is no longer nervous to transfusion, they can feel at ease to have a rest during transfusion for a long time to make it very much.
For reducing the dependence of patient to nurse, control oneself as far as possible and carry out infusion management, the flexible catheter 1 that flexible catheter 1 position at two conductive contact 7 places and flexible catheter 1 access between liquid hard tube 3 is provided with multitube linker 10, multitube linker 10 is provided with two or many liquid flowing tubes 11, liquid flowing tube 11 one end are communicated with multitube linker 10, liquid flowing tube 11 other ends are communicated with gets liquid hard tube 3, and liquid flowing tube 11 is provided with hand switch 12.
After one bottle of liquid is totally lost, flexible catheter motor switch 9 cuts out automatically, on the liquid flowing tube 11 that patient can own communicate another bottle of liquid, hand switch 12 is opened, when the liquid in this bottle flows to two conductive contact 7 positions, two conductive contact 7 conductions, the signal of telecommunication of two conductive contact 7 conductions makes switch controller 8 that flexible catheter motor switch 9 is opened, and the liquid in this bottle is inputted in patient's body by flexible catheter motor switch 9, liquid flow controller switch 5, transfusion needle 4 again.
In switch controller 8, be provided with buzzer.After one bottle of liquid is totally lost, flexible catheter motor switch 9 cuts out automatically, and buzzer is sounded, and oneself is totally lost prompting patient and this bottle of liquid of nurse.The output lead of two conductive contacts 7 also can be communicated with the monitor of nurse's night shift room, directly remind patient nurse liquid oneself be totally lost.
Also comprise a vertical bracing frame, the top height of bracing frame is 2.0 ~ 2.5 meters, and the top of bracing frame is fixed with the free rope of elasticity of many flexible Telescopics, and the differing heights position of the every free rope of elasticity is provided with a plurality of hooks.It is upper that different infusion bottles hangs over the free rope of different elasticity, and the infusion bottle of filled with fluid is heavier and be hung in lower position, along with liquid in infusion process reduces, weight saving, and by the free rope band of elasticity to movement.Its effect is: the liquid in infusion bottle remains unchanged to the infusion pressure matrix of human body, and while avoiding full bottling liquid, fluid pressure is large, and transfusion speed is fast, and in the time will being totally lost for one bottle, fluid pressure is little, and transfusion speed is slow, the problem that even always has minority not export.
Advantage of the present utility model: when patient infusion, after liquid is totally lost, the flexible catheter of transfusion is closed automatically, liquids and gases can not pass through flexible catheter motor switch, gas is that air can not enter human body, so this utility model is safety infusion conduit, and patient can oneself change infusion bottle and infuses, the dependence of minimizing to nurse, minimizing nurse's workload.
