Specific embodiment
For the ease of understanding the utility model, below with reference to relevant drawings to being originally described more fully.
It should be noted that it can be directly to separately when an element is considered as " connection " another element One element and it is in combination be integrated, or may be simultaneously present centering elements.Term as used herein " installation ", " one End ", " other end " and similar statement are for illustrative purposes only.
Referring to FIG. 1, the utility model embodiment provides a kind of visual trachea cannula comprising tube body, camera module And air bag module.Tube body includes tube body 11, crotch 12, tracheal cannula joint 13, and tube body 11 has patient end 8 and machine end 7 Both ends, patient end 8 are located at the distal end of tube body 11, and machine end 7 is located at the proximal end of tube body 11.Meaning is distal and proximal herein, is to grasp Author is reference, and " distal end " i.e. relative to operator apart from longer one end, " proximal end " is i.e. shorter relative to operator's distance One end is exactly specifically left end and the right end of Fig. 1.Machine end 7 is connected with tracheal cannula joint 13, tracheal cannula joint 13 It can be connected with ventilator or Anesthesia machine (not shown).Patient end 8 connects crotch 12, and crotch 12 is made of flexible material, and It is bent towards the central axial direction of tube body 11.Since 11 elastic property of tube body is good, it is not easy kinking, and is resistant to suffer oppression, but phase For body cavities, material is harder, and a soft crotch 12, which is arranged, by the patient end 8 in tube body 11 can make trachea cannula Patient end 8 more easily by relatively narrow body cavities, while avoiding 11 prick into human body's cavity of tube body.
Camera module includes camera 21, camera conducting wire 22, camera connector 23 and camera channel 24.Camera is logical Road 24 is embedded in the tube wall of tube body 11 and one end is located at patient end 8 and runs through tube wall, and camera 21 is located at camera channel 24 It is interior and be located at patient end 8, camera 21 can or detent viscous viscous with glue be fixed in camera channel 24.Camera conducting wire 22 is worn Camera channel 24 is crossed, 22 one end of camera conducting wire is connect with camera 21, and the other end is connect with camera connector 23.Camera Connector 23 can be USB interface, be set to outside tube body 11, and the photographic picture of camera 21 passes through camera conducting wire 22 and camera Connector 23 is transmitted to display equipment, and medical staff is allowed to can be clearly seen that the insertion situation of trachea cannula.
Air bag module includes air bag 31, filling channel 32, inflation line 33 and control valve 35, and air bag 31 is arranged in tube body 11 It outside, and close to patient end 8 is exactly specifically the distance between air bag 31 and patient end 8 than between air bag 31 and machine end 7 Distance it is short.Filling channel 32 is embedded in the tube wall of tube body 11 and one end is connect with air bag 31, and the other end and inflation line 33 connect It connects, control valve 35 is connected to the inflation one end of line 33 far from filling channel 32, and control valve 35 can be check valve, fills for controlling The on-off of gas line 33.Instruction bubble 34 is can connect between inflation line 33 and control valve 35, when trachea cannula is inserted into specific bit It postpones, medical staff will be inflated by control valve 35 toward air bag 31 and instruction bubble 34, by the degrees of expansion for indicating bubble 34 It can determine whether out whether the degrees of expansion of air bag 31 reaches standard.Air bag 31 after expansion makes close between trachea cannula and tracheal wall It closes, convenient for assisted respiartion or control breathing, flows into tracheae prevented also from vomitus, oral secretion or blood.
Referring to FIG. 4, the end face of patient end 8 is inclined-plane 9, inclined-plane 9 and the angle of the axis of tube body 11 are 30 ° -50 °, curved Hook 12 is connected on the distal end on inclined-plane 9.Crotch 12 is bent to the axis direction of tube body 11, and crotch 12 and 11 intersection of tube body are smooth Transition reduces the friction between body cavities and the patient end 8 of trachea cannula.Crotch 12 can be made of PVC material, material It is soft.
Referring to FIG. 4, camera is arranged on the proximal end on inclined-plane 9.Camera 21 is retracted inside relative to inclined-plane 9, and oblique The minimum distance in face 9 is maintained between 0.2mm-1mm, is exposed at camera 21 will not except inclined-plane 9, is both avoided that heavily fortified point in this way Hard camera 21 encounters body cavities, also can guarantee that photographic picture can be clear.On the end face of patient end 8, crotch 12 The distance at center of center to 8 end face of patient end is less than the center in camera channel 24 to the distance at the center of crotch 12, and curved The center of hook 12 to 8 end face of patient end the distance at center at a distance from the center to the center of crotch 12 in camera channel 24 it Than for 1:1.6-2, thus being avoided that crotch 12 stops the shooting of camera 21.
Referring to FIG. 3, tube body 11 is provided with irrigation channel 41 in the inner wall in camera channel 24, irrigation channel 41 is set It is equipped with towards camera 21 and is connected to the flushing hole 42 in camera channel 24, flushing hole 42 is located at camera 21 close to patient end 8 Side.There is 1-3mm between camera channel 24 and irrigation channel 41 separated by a distance, irrigation channel 41 is close to inclined-plane 9 Position bends 50 ° of -80 ° of direction cameras 21, forms the inclination flushing hole 42 for rinsing camera 21.Effect is rinsed in order to reach Fruit, flushing hole 42 is located at 41 front end of irrigation channel, and is substantially flush with camera 21.11 outside of tube body is connect with irrigation channel 41 Have flushing pipe and flush-through connection (not shown), have before camera 21 sundries hinder shooting when, medical staff using note The flushing devices such as emitter are connected to flush-through connection, the sundries before camera 21 is fallen by injection air or liquid wash.This method Simple ingenious, flushing effect is good, can efficiently reduce the pain of patient.
Referring to FIG. 2, being provided with the hole Mo Fei 5 on the side wall of the tube body 11 between patient end 8 and air bag 31.In tube body 11 It may be provided with the spring 6 that can be matched with 11 inner wall of tube body, spring 6 is wound in trachea cannula inner wall, utilizes the elasticity of spring 6 Performance is good, is not easy kinking, and be resistant to the characteristic to suffer oppression, and angulation can be folded to make trachea cannula by avoiding trachea cannula stress It ventilates unsmooth phenomenon, reduces the generation of malpractice.
The utility model provides a kind of visual trachea cannula, by being provided with camera 21 and softness in trachea cannula front end Crotch 12, monitor the process of entire trachea cannula operation can by dynamic video, make trachea cannula operation under visualization It carrying out, operation fast and safely, accurately, while also avoiding trachea cannula front end from causing to damage to body cavities in catheterization procedure, It is small to body cavities damage, improve the safety and success rate of operation.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, all should be considered as described in this specification.
