Abstract
The utility model relates to a drug interjecting type trachea canal, containing a trachea canal body, wherein, the inner wall on one side of the trachea canal has an air interjecting tube, whereas the other inner wall has a drug interjecting tube. One end of the air interjecting tube is connected with a gasbag, whereas the other end is connected with an air interjecting opening which is connected with an air interjecting valve. One end of the drug interjecting tube is threaded towards the front end of the air interjecting tube along the tube wall of the air interjecting tube, whereas the other end is connected with an injecting opening of a drug interjecting valve. A helix component of the drug interjecting tube has a plurality of millipores at the outer side face of the trachea canal, except the component wound on the airbag. The utility model can be widely used in clinic, so as to reduce the drug dosage of a wholly anaesthetized patient, ensure the stable wake up of the patient and release the patient who wears a trachea canal for a long time; moreover, the utility model is practical and convenient, low in cost and suitable to be popularized.
Description
(1) technical field
This utility model relates to a kind of endotracheal tube, but particularly a kind of medicine infusion type endotracheal tube.
(2) background technology
The fast development with respirator updated along with the general anesthesia technology, the application of general anesthesia in operation more and more widely, and along with the extensive application of respirator in clinical, the situation of carrying out respirator treatment and rescue after critical patient's tracheal intubation is more and more.But no matter be the induction and tracheal intubation of general anesthesia operation, during postoperative general anesthesia is revived or the critical patient keeps somewhere endotracheal tube and carry out respirator treatment and rescue, patient can stimulate tracheal mucosa because of endotracheal tube, cause significant hemodynamic change, showing as chokes coughs, feel sick, vomiting, blood pressure are increased, increased heart rate, and this to patient especially and to deposit the patient of hypertension, coronary heart disease and high intracranial pressure totally unfavorable.Address this problem adopt in the preceding single trachea of tracheal intubation at present clinically injects topical anesthetic cream and uses calm in a large number, two kinds of methods of analgesics more.But the single intratracheal superficial anesthesia only can act on 20-40 minute, revive stage and need long-time patient's effect of keeping somewhere endotracheal tube very little for operation, in addition, a large amount of hematodinamicss that use calm, analgesics can cause general anesthesia patient to revive delays, influences the critical patient are stablized, to patient revive and heal after cause adverse effect.
(3) summary of the invention
This utility model is in order to solve general anesthesia patient revive problem that choking of stage cough, feel sick, vomit and the misery of keeping somewhere the endotracheal tube patient for a long time, but a kind of medicine infusion type endotracheal tube is provided.
This utility model is realized by following measure: but a kind of medicine infusion type endotracheal tube comprises the endotracheal tube body, described conductance body one side inwall is provided with air injection pipe, and the opposite side inwall is provided with medicine-pouring pipe.
Its further improvements are: an end of described air injection pipe is connected with air bag, and the other end is connected to the gas injection port that is connected with the gas injection valve.
Its further improvements be: in the shape of a spiral downwards until endotracheal tube body front end, the other end is the injection port that is connected with the injection valve to described medicine-pouring pipe one end in the tube wall of endotracheal tube body.
For medicine can be sprayed uniformly, described medicine-pouring pipe spiral part removes the part that is wrapped on the air bag and has a plurality of micropores to the lateral surface of endotracheal tube.
Operation principle of the present utility model: the caused hemodynamic variation of endotracheal tube mainly is to stimulate sympathetic-adrenal gland's energy system when being subjected to mechanical stimulus owing to tracheal mucosa, cause sympathetic-parasympathetic nervous reflection, cause plasma norepinephrine to increase, sympathetic activity strengthens, the topical anesthetic that injects can absorb by tracheal mucosa, make the interior mucosa of trachea by local anesthesia, stablize neuron membrane, be that the sensor that produces the stress reflection promptly is blocked in the starting point of reflex arc, thereby suppress and reduce the generation and the conduction of noxious stimulus neural impulse, fundamentally suppress the reaction of sympathoadrenal medullary substance.
The beneficial effects of the utility model: can be widely used in clinical, can reduce general anesthesia patient dosage, guarantee that general anesthesia revives steadily, alleviate long-time indwelling endotracheal tube patient's misery, convenient and practical, with low cost, suitable applying.
(4) description of drawings
Below in conjunction with drawings and Examples this utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
1 air bag among the figure, 2 micropores, 3 injection valves, 4 medicine-pouring pipes, 5 endotracheal tube bodies, 6 gas injection pins, 7 gas injection valves, 8 air injection pipe, 9 syringe needles.
(5) specific embodiment
But a kind of medicine infusion type endotracheal tube as shown in Figure 1 comprises endotracheal tube body 5, and described conductance body 5 one side inwalls are provided with air injection pipe 8, the opposite side inwall is provided with medicine-pouring pipe 4.
One end of described air injection pipe 8 is connected with the air bag 1 that is looped around endotracheal tube body 5 front end peripheries, and the other end is the gas injection port that is connected with gas injection valve 7.
In the shape of a spiral downwards until endotracheal tube body 5 front ends, and in the front end sealing, the other end is the injection port that is connected with injection valve 3 to described medicine-pouring pipe 4 one ends in the tube wall of endotracheal tube body 5.
Described medicine-pouring pipe 4 spiral parts part has 32 micropores 2 to the lateral surface of endotracheal tube, is wrapped in except the part on the air bag 1, and when medicine-pouring pipe 4 injections, medicine sprays around endotracheal tube body 5 uniformly by micropore 2.
Whether use routine examination air bag 1 leaks gas, whether injection catheter is unobstructed, to inject topical anesthetics by syringe needle 9 to medicine-pouring pipe 4 behind the endotracheal tube body 5 insertion tracheas, reuse gas injection pin 6 is full of air bag 1 by air injection pipe 8, can be interrupted the injection topical anesthetic according to patient's needs, first emptying air bag 1 before the injection, the medicine that reinjects is evenly distributed medicine.
