Abstract
The invention provides an anti-air-intake type transfusion needle catheter for safely and conveniently replacing a transfusion bottle, belongs to medical equipment, and particularly relates to a transfusion catheter for transfusion. The transfusion catheter is provided with an automatic switching system, wherein the automatic switching system comprises two conductive contacts, a switching controller and a soft catheter electric switch which are connected in sequence; the two conductive contacts output a switching signal to the switching controller and the switching controller outputs electric energy for driving a switch to move to the soft catheter electric switch; the two conductive contacts of the automatic switching system are arranged in a soft catheter and an output lead of the two conductive contacts is connected with the switching controller; the soft catheter electric switch is arranged on the soft catheter between the positions of the two conductive contacts in the soft catheter and a soft catheter connected transfusion needle; the soft catheter electric switch is connected with the switching controller. The anti-air-intake type transfusion needle catheter has the advantages that the soft catheter for transfusion is automatically closed after liquid is transfused and the liquid and air can not pass through the soft catheter electric switch, so that the air can not enter a human body and the transfusion catheter is a safe transfusion catheter.
Description
Technical field
The invention belongs to medical devices, the infusion needle guide tube used of particularly infusing.
Background technology
When liquid in infusion bottle has soon flowed, as closed the switch on transfusion catheter not in time, air will input into human body by present transfusion catheter, and cause thrombosis to cause transfusion people dead, this is the problem that long-standing problem nurses the sick.So it is all very nervous to transfusion to protect soil, the Nursing personnel of transfusion patient and patient, make its them not bery to feel at ease to have a rest during transfusion for a long time.
Summary of the invention
The object of this invention is to provide after a kind of liquid is totally lost, air can not be had to input safety infusion wire guide into human body, but and patient oneself changes the infusion needle guide tube of infusion bottle.
Structure of the present invention 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 thrusting 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 making flexible catheter 1 conducting or closedown; Automatic switching system 6 comprises two conductive contacts 7, switch controller 8 and the flexible catheter motor switch 9 that are connected successively, two conductive contacts 7 are to switch controller 8 output switching signal, and switch controller 8 exports the electric energy of driving switch action to flexible catheter motor switch 9;
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, carries out conducting or closedown to flexible catheter 1.
Because medicinal liquid in flexible catheter 1 always conducts electricity, when there being liquid in flexible catheter 1, two conductive contacts 7 conduct electricity, two conductive contacts 7 export the signal allowing flexible catheter motor switch 9 open to switch controller 8, then switch controller 8 exports electric energy to flexible catheter motor switch 9 and opens normal infusion by flexible catheter motor switch 9.When there is no liquid in flexible catheter 1, two conductive contacts 7 disconnect non-conductive naturally, two conductive contacts 7 export the signal allowing flexible catheter motor switch 9 close to switch controller 8, then switch controller 8 exports electric energy to flexible catheter motor switch 9, and automatically allowing flexible catheter motor switch 9 close can not have liquids and gases by flexible catheter motor switch 9.Namely one bottle of transfusion liquid is automatically realized after being totally lost, flexible catheter 1 is closed automatically, prevent from gas from flowing to transfusion needle 4 from flexible catheter 1 to be input to again among human body, automatically the insecurity of transfusion is prevented, patient is when infusing, allow to protect soil, the Nursing personnel of transfusion patient and patient no longer nervous to transfusion, make its them can feel at ease to have a rest very much during transfusion for a long time.
For reducing patient to the dependence of 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 is communicated with multitube linker 10, liquid flowing tube 11 other end is 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 another bottle of liquid can oneself communicate by patient, hand switch 12 is opened, when the liquid in this bottle flows to two conductive contact 7 positions, two conductive contacts 7 conduct electricity, the signal of telecommunication that two conductive contacts 7 conduct electricity makes switch controller 8 that flexible catheter motor switch 9 is opened, and the liquid in this bottle is again by flexible catheter motor switch 9, liquid flow controller switch 5, transfusion needle 4 and inputting in the body of patient.
Buzzer is provided with in switch controller 8.After one bottle of liquid is totally lost, flexible catheter motor switch 9 cuts out automatically, and buzzer is sounded, remind patient and nurse's this bottle of liquid oneself be totally lost.The output lead of two conductive contacts 7 also can be communicated with the monitor of nurse's night shift room, directly remind the liquid of patient nurse oneself be totally lost.
Also comprise a vertical bracing frame, the tip 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 dissociate differing heights position of rope of every bar elasticity is provided with multiple hook.Different infusion bottles hangs on 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, then and weight saving, and dissociated on rope band to movement by elasticity.Its effect is: the infusion pressure matrix of the liquid in infusion bottle to human body remains unchanged, and when avoiding full bottling liquid, fluid pressure is large, and transfusion speed is fast, and when being totally lost for one bottle, fluid pressure is little, and transfusion speed is slow, even always has the problem that minority can not export.
Advantage of the present invention: when patient infusion, after liquid is totally lost, the flexible catheter of transfusion is closed automatically, liquids and gases are not by flexible catheter motor switch, gas and air can not enter human body, so the present invention is safety infusion conduit, but and patient oneself change infusion bottle infuse again, reduce the dependence to nurse, reduce the workload of nurse.
