Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of medical devices, in particular to a laryngoscope blade. BACKGROUND
[0002] Due to the deep position of the larynx and the complex physiological structure, the larynx cannot be directly observed, and the larynx needs to be examined with the help of a laryngoscope.
[0003] Traditional laryngoscope blades are divided into disposable laryngoscope blades and reusable laryngoscope blades. The laryngoscope blade has various length models according to the front segment of the blade, for adults and children. According to the actual situation of the patient, different models of laryngoscope blades are selected for laryngoscopy.
[0004] Due to the large difference in oral width of children of different ages, a single model of laryngoscope blade cannot meet the use requirements of subjects of different age groups. In addition, the touch of newborns and young children is sensitive. After the laryngoscope enters the oral cavity, the subject's tongue is easily randomly swung after being stimulated by the laryngoscope. The subject is too young to control the swing of the tongue well. If the width of the laryngoscope blade is small, the baffle cannot well limit the movement of the tongue, and the tongue will greatly interfere with the doctor's tracheal intubation operation, increasing the difficulty of tracheal intubation and affecting the doctor's observation of the subject's larynx. CONTENT OF THE INVENTION

[0037] The traction member 301 is provided in the main body 101 along the extension direction of the main body 101, the main body 101 is adapted to the physiological curve change from the oral cavity to the larynx, the main body 101 has a curvature, and the traction member 301 is flexible, so that the traction member 301 can bend to a certain extent when moving, thereby enabling the traction member 301 to move in and out of the main body 101 along the extension direction of the main body 101.
[0038] The two baffles 201 are respectively provided on the left and right sides of the main body 101, and the baffles 201 are slidingly connected with the main body 101 and can move along the width direction of the main body 101.
[0039] The traction member 301 is provided between the two baffles 201, and the two baffles 201 are respectively provided with guide grooves 202, which gradually approach or move away from the traction member 301 along the extension direction of the main body 101 towards the distal end of the main body 101. The traction member 301 is slidingly connected with the guide grooves 202 of the two baffles 201 through the sliding portion 302 which is rigid, and when the traction member 301 moves in and out of the main body 101 along the extension direction of the main body 101, the traction member 301 drives the two baffles 201 to move towards or away from each other along the width direction of the main body 101.
[0040] The distal end of the main body 101 can be inserted into the larynx of a subject, as shown in Figures 3 to 5 , along the extension direction of the main body 101 towards the distal end of the main body 101, the guide grooves 202 gradually approach the traction member 301, and the traction member 301 is provided with the sliding portion 302 which is slidingly connected with the guide grooves 202. When the traction member 301 drives the sliding portion 302 to move away from the distal end of the main body 101 (described in the direction of Figure 4 、 Figure 5 , when the traction member 301 moves upwards), the transverse distance of the sliding portion 302 which is rigid does not change, and the distance between the guide grooves 202 and the traction member 301 has a gradually increasing trend, so that under the action of the sliding portion 302, the two baffles 201 move towards the traction member 301, the distance between the guide grooves 202 at the connection with the sliding portion 302 and the traction member 301 remains unchanged, and the two baffles 201 move towards each other along the width direction of the main body 101, as shown in Figure 5When the sliding part 302 is moved toward the distal end of the main body 101 by the traction member 301, the lateral distance of the sliding part 302 with rigidity does not change, and the distance between the guide groove 202 and the traction member 301 gradually decreases, so that the two baffles 201 are away from the traction member 301 under the action of the sliding part 302, the distance between the guide groove 202 and the traction member 301 is kept unchanged, and the two baffles 201 are away from each other along the width direction of the main body 101. The operator can adjust the position of the sliding part 302 relative to the guide groove 202 by the traction member 301, so as to change the width of the laryngoscope blade, so that the laryngoscope blade can adapt to the oral width of different subjects.
[0041] Of course, the arrangement of the guide groove 202 is not limited to the above-mentioned manner of gradually approaching the traction member 301 along the extension direction of the main body 101 toward the distal end of the main body 101. The guide groove 202 can gradually move away from the traction member 301 along the extension direction of the main body 101 toward the distal end of the main body 101, as shown in Figure 6 , and the two baffles 201 are away from each other when the sliding part 302 is moved away from the distal end of the main body 101, and the two baffles 201 are close to each other when the sliding part 302 is moved toward the distal end of the main body 101. Here, it is not repeated.
[0042] In an embodiment of the present application, the free end 303 of the traction member 301 is arranged outside the main body 101, and the connecting end 304 of the traction member 301 is connected to the main body 101 through the elastic member 103. The elastic member 103 can be a spring, rubber or other elastic member. The medical staff can pull the free end 303 to move the traction member 301 in one direction along the extension direction of the main body 101, and at the same time, the elastic member 103 is elastically deformed; when the medical staff removes the pulling force of the traction member 301, the traction member 301 can be reset under the action of the elastic member 103, and move in the opposite direction, as shown in Figure 1 , Figure 4 When the medical staff pulls the traction member 301 to move away from the distal end of the main body 101, the elastic member 103 is elastically deformed, and when the medical staff removes the pulling force, the traction member 301 moves toward the distal end of the main body 101.
