Abstract
The utility model relates to a visual trachea catheter core, belonging to an auxiliary implement in medical operations. The visual trachea catheter core is suitable for observing a trachea when oxygen is delivered to a patient. The visual trachea catheter core is mainly composed of a minityped prefocus lamp which is connected with two wires with limited length. Each wire is sheathed with an insulating outer sleeve pipe and is supplied with power by direct current power supply. By using the visual trachea catheter core, the inserting position of a catheter into a trachea can be directly viewed and the catheter can be successfully inserted at one time. Therefore, the inserting time of catheter into the trachea can be shortened to enable the patient to safely get over the difficulty of catheter insertion into the trachea.
Description
This utility model is a kind of medical operating assistive device, is applicable to when the patient cured by oxygen therapy trachea is observed.
Before the operation that anaesthetizes sb. generally, rescue with respiratoring palpitating suddenly stopping, and respiratory failure is when needing operation such as mechanical ventilation, need cure by oxygen therapy and need intubate is inserted trachea to the patient, before the intubate is the anaerobic metabolism phase, this section time lengthening will be brought important organ anoxia time lengthening for patient, increase complication and cause the anesthetic accident accident.So intubate is that insertion trachea or esophagus are the successful keys of operation.The judgement of intubate success at present is mainly by (1) operator's vision and sensation; (2) push whether air-flow is arranged in the thorax conduit; (3) two lung auscultations; (4) pressurization oxygen supply thorax fluctuating situation; (5) air-flow expiration sound in the screw tube.There is a time difference problem in above-mentioned several method, in case the conduit enter the esophagus by mistake need heavily expose glottis, particularly glottis difficult exposure person, more difficult success.
The purpose of this utility model designs a kind of catheter core of inserting tracheal intubation, can intuitively see the position of intubate.Make the tracheal intubation success rate reach 100%, shorten the time of tracheal intubation, make patient safety tide over the tracheal intubation difficulty.
This utility model is like this design, a miniature spot light lamp bulb two leads of ining succession, and lead is with the insulating coating pipe outward.Wherein a lead has certain intensity.Whole catheter core length is not less than 25CM, and its diameter is not more than 8MM, and for making things convenient for direct current supply, two wire ends can connect a socket.Power supply can connect power supply with rectifier power source or with battery case.
The advantage of visual endotracheal tube core like this has: deficiency and laryngoscope that (1) remedies the laryngoscope light source break down; (2) judge from the luminous point that covers on larynx, the trachea skin whether catheter position is correct, above Adam's apple, the residing correct position of expression endotracheal tube is if be offset or can't see luminous point and represent that conduit position herein is wrong on Adam's apple to both sides as luminous point; (3) luminous point moves down the expression conduit in trachea along Adam's apple, trachea from Adam's apple, otherwise not in trachea.Saved the dial-out tube core like this, pushed thorax, auscultation of lung, pressurization oxygen supply wait and judge that whether conduit is in the endotracheal time; (4) distance that moves down from luminous point can accurately be grasped catheter depth, has avoided the auscultation of two lungs after the intubate, makes the tracheal intubation one-time-reach-place, has guaranteed that the tracheal intubation success rate reaches 100%.
This utility model is realized by following drawings and Examples:
Accompanying drawing is the overall structure sketch map.
Miniature spot light lamp bulb 1 in succession lead 2 and copper bare wire 3 are arranged among the figure, lead 2 and the copper bare wire 3 outer plastic outer sleeves 4 that are with, miniature spot light lamp bulb 1 adopts the laryngoscope bulb of 3V power supply, the about 5MM of its diameter, plastic outer sleeve 4 external diameters also are about 5MM, the about 50CM of length of this utility model design.Convenient for connecing power supply, at wire end attaching socket 5.The power supply AC rectification gets final product for direct current 3V connects a plug, perhaps inserts battery case with two batteries and also can.
Claims (3)
1, visual endotracheal tube core is a kind of medical operating assistive device, is applicable to when the patient cured by oxygen therapy that to the observation of trachea, it is characterized in that: miniature spot light lamp bulb 1 is connected with lead 2 and 3, two line overcoats of lead insulating coating pipe 4.
2, visual endotracheal tube core according to claim 1, it is characterized in that: catheter core length is not less than 25CM, and its diameter is not more than 8MM.
