Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically is the used EVD device of neuro-surgery.
Background technology
In the clinical treatment of the current many diseases of neurosurgery, comprise cerebroma, the damage of severe intracranial, the treatment of hypertensive cerebral hemorrhage etc. all needs to use disposable EVD device.Present this device one is to use cumbersome, when especially needing intracranial to inject hemolytic agent or antibiotic etc, needs unplug from the joint, and complex operation, and easily cause intracranial infection, crisis patient life security; The 2nd, there is not the scale that intuitively reads intracranial pressure; The 3rd, cost an arm and a leg, patient's financial burden is overweight.
The utility model content
Technical problem to be solved in the utility model is in order to overcome above-mentioned defective, and a kind of simplicity of design, easy to operate, disposable EVD device that price is low, safe in utilization are provided.
In order to solve the problems of the technologies described above, the technical scheme that this utility model adopted is: this disposable EVD device, comprise drainage bottle and the input pipe and the outlet tube that communicate with the drainage bottle inner chamber, the part of input pipe stretches into the inner chamber of drainage bottle and has scale, it is characterized in that: be positioned at the outer input pipe of drainage bottle and be provided with threeway, the end of outlet tube connects drainage bag, and the bottom centre of drainage bag is provided with the hassock injection mo(u)lding.The hassock good sealing effect prevents germ contamination, the convenient liquid of extracting out.
Outer input pipe and the outlet tube of drainage bottle is flexible pipe, and the end is provided with the patch plug that is connected with the ventricular drainage tube end.Be convenient to connect.
Have scale on the input pipe of drainage bottle, drainage bottle inner chamber, the drainage bag.Be convenient to read intracranial pressure value and trickle is measured and observes.
According to clinical needs, available asepsis injector is extracted the cerebrospinal fluid in the drainage bag out by hassock, and it is biochemical and conventional to be used to chemically examine cerebrospinal fluid.Threeway is medical conventional threeway, is mainly used in the adjusting direction, according to change of illness state and clinical needs, leads to Intraventricular or medicines such as cephalophyma intracavity injection hemolytic agent or antibiotic by three.
Using method: the input pipe of drainage bottle connects the EVD pipe, and cerebrospinal fluid flows into input pipe, can read the intracranial pressure value at any time from the scale of the input pipe of drainage bottle, drainage bottle inner chamber.When intracranial pressure was high, cerebrospinal fluid overflowed from input pipe, entered drainage bottle, entered drainage bag by outlet tube again.
Compared with prior art the beneficial effect that this utility model had is: disposable EVD device of the present utility model, owing to increased threeway, can be according to clinical needs, regulate the threeway direction, realize drain easily or inject hemolytic agent or antibiotic etc to Intraventricular or cephalophyma intracavity, easy to use; The drainage bag bottom installs hassock additional, can increase aseptic degree, and disposable use reduces infection chance, uses as safe as a house.Have scale on the input pipe of drainage bottle, drainage bottle inner chamber, the drainage bag, can read the intracranial pressure value at any time.This utility model is simple in structure, easy to operate in addition, and price is low, effectively alleviates patient's financial burden.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 threeway, 2 input pipes, 3 drainage bottles, 4 outlet tubes, 5 drainage bags, 6 hassocks.
The specific embodiment
As shown in Figure 1, this disposable EVD device, form by threeway 1, input pipe 2, drainage bottle 3, outlet tube 4, drainage bag 5, hassock 6, be made into integral type with a soft silica gel or an injection moulding of similar disposable infusion modulator material, the input pipe 2 that is positioned at drainage bottle 3 inner chambers has scale, the input pipe 2 of drainage bottle 3 outsides is provided with medical conventional threeway 1, outlet tube 4 is positioned at the below, side of drainage bottle 3 and communicates with drainage bottle 3 inner chambers, the end of outlet tube 4 is connected with drainage bag 5, and hassock 6 is positioned at the bottom centre of drainage bag 3.Threeway 1 is set can be according to change of illness state and clinical needs, adjust input and output, drain under the normal condition, when needs when Intraventricular or cephalophyma intracavity inject hemolytic agent or antibiotic medicine, can realize by threeway 1.According to clinical needs, available syringe is extracted the cerebrospinal fluid in the drainage bag 3 out by hassock 6, and it is biochemical and conventional to be used to chemically examine cerebrospinal fluid.
Using method: the input pipe 2 of drainage bottle 3 connects the EVD pipe, and cerebrospinal fluid flows into input pipe 2, can read the intracranial pressure value at any time by the input pipe scale from drainage bottle 3.When intracranial pressure was high, cerebrospinal fluid overflowed from input pipe 2 tops, enters drainage bottle 3, flowed into drainage bag 5 by outlet tube 4 again.
This disposable EVD device owing to increased threeway 1, can inject hemolytic agent or antibiotic medicine to Intraventricular or cephalophyma intracavity easily according to clinical needs, and is easy to use; The drainage bag bottom installs rubber hassock 6 additional, can increase aseptic degree, reduces infection chance.Have scale on the input pipe 2 of drainage bottle 3, drainage bottle inner chamber, the drainage bag 5.Can from the scale of the input pipe 2 of drainage bottle 3, drainage bottle inner chamber and drainage bag 5, read the intracranial pressure value at any time.This disposable EVD device is easy to operate, and price is low, effectively alleviates patient's financial burden.
