Description

Disposable use multifunctional endotracheal intubation

Technical field:

This utility model relates to a kind of medical apparatus of clinical use, specifically is a kind of disposable use multifunctional endotracheal intubation.

Background technology:

For the surgical patient of general anesthesia, because its health loses one's senses, medical personnel need use tracheal intubation to come patient is carried out assisted respiartion.Existing tracheal intubation generally comprises one and is used to insert the conduit in the patient's trachea, and catheter head is equipped with the air bag that is used for gap between closes ducts and the patient's trachea wall, on the conduit of air bag head temperature probe is housed; Be provided with gas tube and holding wire in the catheter wall; Gas tube one end communicates with air bag, and the gas tube other end is drawn from catheter tail and is used for being connected with outside charger, and holding wire one end is connected with temperature probe; The holding wire other end is drawn from catheter tail and is used for being connected with the external temperature monitor; During use, conduit is inserted in the patient's trachea by patient's mouth, come the patient under the narcotism is got into auxiliary the absorption through delivering oxygen in the conductive pipe.Use above-mentioned tracheal intubation to carry out in the process of assisted respiartion for the anesthesia patient, a large amount of sputums are accumulated through regular meeting in the air bag bottom, for timely these sputums of sucking-off; Keep respiratory passage unblocked, the conventional way of medical personnel is: at first stop delivering oxygen in the conductive pipe, promptly stop the supple of gas or steam; Emit the gas in the air bag then; Conduit is transferred in patient's trachea, is used dedicated suction expectorant instrument that the sputum in the patient's trachea is siphoned away at last, treat that sputum is all siphoned away after; Again conduit is inserted in the patient's trachea, and connects outside oxygen supply equipment and continue to the logical oxygen of conduit.Yet, carry out in the whole process of assisted respiartion for the anesthesia patient, medical personnel will use said method to inhale expectorant to patient at set intervals, and repeated operation and loaded down with trivial details process can be brought very burden to medical personnel undoubtedly.

In addition, when conduit inserts patient's trachea, because the stimulation of conduit; Patient has vomiting reaction, can accumulate the air bag top from the effusive food debris of esophagus, in order in time to clear up food debris; Syringe pipe also is housed in the catheter wall, and the conduit outer wall of air bag afterbody is provided with the flushing hole that communicates with syringe pipe, during use; At first in syringe pipe, pour into normal saline and come the air bag top is washed, and then utilize syringe pipe that food debris is siphoned away, because flushing and the shared same syringe pipe of sucking-off food debris; Therefore cause flushing and sucking-off food debris to carry out simultaneously; For the food debris at air bag top is thoroughly cleaned out, medical personnel need replace flushing and sucking-off work repeatedly, and this also brings very burden to medical personnel.

The utility model content:

The technical problem that this utility model will solve is, provide a kind of just can be under need not to transfer to the situation of conduit with the sputum sucking-off in the patient's trachea, thereby the disposable use multifunctional endotracheal intubation that makes things convenient for medical personnel to operate.

The technical solution of this utility model is that a kind of disposable use multifunctional endotracheal intubation with following structure is provided: comprise being used to insert the conduit in the patient's trachea that catheter head is equipped with the air bag that is used for gap between closes ducts and the patient's trachea wall; On the conduit of air bag head temperature probe is housed, has flushing hole on the conduit outer wall of air bag afterbody, be provided with syringe pipe, gas tube and holding wire in the catheter wall; Syringe pipe communicates with flushing hole; Gas tube communicates with air bag, and holding wire is electrically connected with temperature probe, wherein; Also be provided with first sputum aspirator tube in the catheter wall; Have radial direction through hole on the catheter wall between temperature probe and the air bag, first sputum aspirator tube, one end communicates with radial direction through hole, and the first sputum aspirator tube other end is drawn from catheter tail and is used for being connected with the negative exterior press.

The described disposable use multifunctional endotracheal intubation of this utility model; Wherein, Also can be provided with second sputum aspirator tube in the catheter wall, have sputum suction hole on the conduit outer wall of air bag afterbody, second sputum aspirator tube, one end communicates with sputum suction hole; The second sputum aspirator tube other end is used for being connected with the negative exterior press, is connected with first capping that is used to seal second sputum aspirator tube on second sputum aspirator tube.

The described disposable use multifunctional endotracheal intubation of this utility model, wherein, sputum suction hole can be symmetrical with flushing hole.

The described disposable use multifunctional endotracheal intubation of this utility model, wherein, radial direction through hole can have two; First sputum aspirator tube has two; Two radial direction through hole are symmetrical, and two first sputum aspirator tube one ends communicate with two radial direction through hole respectively, and the two first sputum aspirator tube other ends are connected with the negative pressure pipe through threeway and communicate; The negative pressure pipe is used for being connected with Negative pressure machine, is connected with second capping that is used for the closed negative pressure pipe on the negative pressure pipe.

After adopting above structure; Compared with prior art, the disposable use multifunctional endotracheal intubation of this utility model has the following advantages: need in patient's trachea, to transfer to the conduit just can the sputum sucking-off in the patient's trachea is different with the prior art tracheal intubation, the disposable use multifunctional endotracheal intubation of this utility model has radial direction through hole on the catheter wall between temperature probe and the air bag; Therefore; Medical personnel use the disposable use multifunctional endotracheal intubation of this utility model in assist the process that absorbs to patient, if sputum is arranged at the air bag bottom, medical personnel can be under the situation of not transfering to conduit; Negative pressure machine is connected on first sputum aspirator tube; Open Negative pressure machine, the sputum in the patient's trachea will flow in the radial direction through hole and first sputum aspirator tube, finally by the Negative pressure machine sucking-off.In addition, the setting of radial direction through hole both can be with the sputum sucking-off that enters into the catheter head inner chamber, again can be with the sputum sucking-off between conduit outer wall and the tracheal wall.

The setting of the sputum suction hole and second sputum aspirator tube can be when syringe pipe washes air bag; Use the food debris sucking-off of Negative pressure machine with the air bag top; Promptly wash on one side, on one side the sucking-off food debris, prior art flushing and the shared same syringe pipe of sucking-off food debris solved; Thereby cause medical personnel need replace the technical barrier that flushing and sucking-off work could thoroughly be cleaned out the food debris at air bag top repeatedly, further greatly facilitate operation of medical workers.
