The specific embodiment
Enumerating a specific embodiment below also is specifically described the specific embodiment of the present invention in conjunction with the accompanying drawings.
As Fig. 1-shown in Figure 6, a specific embodiment of the present invention mainly is made up of handle 1, stay pipe 2, optical fiber 3, nut deck 4, control circuit, illumination component, battery, slide block 8, strip electrode 9.The rear of stay pipe 2 stretches into the inside of handle 1, and the leading portion of stay pipe 2 is positioned at the outside of handle 1 and is positioned at the below of handle 1; Control circuit (not shown in the accompanying drawings) is arranged in the handle 1; Handle 1 inside is provided with 3 strip electrodes 9; Tail end at stay pipe 2 is connected with slide block 8, and slide block 8 is positioned at handle 1 inside fully; Optical fiber 3 is arranged in the stay pipe 2 and the two ends of stretching out stay pipe 2; Nut deck 4 is positioned at handle 1 lower end and is connected with handle 1 by screw thread; Battery (not shown in the accompanying drawings) is arranged in the handle 1, and battery is non-dismountable, adopts rechargeable lithium battary, charges by the charging hole that charging port lid 14 is sealed; Illumination component (not shown in the accompanying drawings) adopts the micro semiconductor laser device, produces red light, is arranged in the slide block 8; Slide block 8 is provided with 3 elastic electrodes (not shown in the accompanying drawings), and each elastic electrode and a strip electrode carry out Elastic Contact, and slide block 8 is provided with index 10, and index 10 adopts the optical material manufacturing; A side of handle 1 is provided with transparency window 6; Index 10 guides to the side at transparency window 6 places with a part of light that the micro semiconductor laser device produces, and can be observed the position of index 10 by transparency window 6 from handle 1 outside.
Control circuit mainly is made up of on and off switch 7, lead (not shown in the accompanying drawings), charging socket (not shown in the accompanying drawings).
One end of optical fiber 3 arrives at the front end of stay pipe 2, and the other end of optical fiber 3 arrives at slide block 8, and a part of illuminating ray that the micro semiconductor laser device in the slide block 8 produces is conducted to the front end outside of stay pipe 2 by optical fiber 3.
Be provided with a petal distortion pawl 13 in the lower end of handle 1, distortion pawl 13 is made up of 4 lobes.As shown in Figure 6, distortion pawl 13 is entangled by nut deck 4, between distortion pawl 13 and stay pipe 2 spring-backed quill 12 is set, and spring-backed quill 12 is used to cushion the pressure of distortion pawl 13 and handle 1 inner space is sealed.User's rotatable nut deck 4, nut deck 4 move to handle 1 under the guiding of screw thread and draw close, and like this, nut deck 4 just applies rock deformation pressure to distortion pawl 13, and then stay pipe 2 is clamped.When the user unscrews nut deck 4, be out of shape pawl 13 and rely on the elasticity of self to realize resilience, the user is removable stay pipe 2 at this moment, and stay pipe 2 drives slide blocks 8 and moves.Distortion pawl 13 belongs to the part of handle 1.Therefore, 13 pairs of stay pipes 2 of distortion pawl fixedly is adjustable.
The lead of micro semiconductor laser device is connected to the elastic electrode on the slide block 8, and strip electrode 9 is connected with control circuit, and battery is connected with control circuit.Elastic Contact between elastic electrode on the slide block 8 and the strip electrode 9, the micro semiconductor laser device is realized itself and being connected of control circuit by this Elastic Contact, the elastic electrode on user's promotion sliding block 8 slides on strip electrode 9.
Therefore, can slide relatively between stay pipe 2 and the handle 1, can indicate the location status of stay pipe 2 by index 10.No matter the user uses the endotracheal tube of which kind of length, user's hands is held near the upper end (that is, the middle hypomere of handle 1 and nut deck 4) of endotracheal tube 11 all the time, and then obtains best operational comfort.As shown in Figure 3, the position of stay pipe 2 is adjustable, i.e. the total length scalable of this specific embodiment of the present invention.
As shown in Figure 6, the upper end of endotracheal tube 11 is blocked in the lower end of nut deck 4; Nut deck 4 is provided with passage 5, and passage 5 is space and external communications in the endotracheal tube 11, unobstructed with the breathing path that guarantees patient in the process of carrying out tracheal intubation.
When the doctor carries out tracheal intubation to patient, endotracheal tube 11 is brought in the human body by this specific embodiment of the present invention, after the front end of stay pipe 2 enters patient's glottis, from the light transmission patient's trachea of optical fiber 3 ejaculations and the tissue between the portion of throat, produce a hot spot on patient's skin of anterior portion of neck, the doctor determines by observing this hot spot whether endotracheal tube 11 has been sent to suitable position.After endotracheal tube 11 had arrived correct position, the doctor just can extract this specific embodiment of the present invention and endotracheal tube 11 is stayed in the patient body in the patient body.
