[0026] In the description of the present invention, "multiple" means at least two, such as two, three, etc., unless otherwise clearly defined. In addition, unless otherwise clearly defined and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] See also Figure 1The utility model provides a technical solution: a suction-type multifunctional laryngoscope blade device, comprising a laryngoscope blade 1, a suction tube 2 and a tongue depressor 3, the laryngoscope blade 1 comprising a proximal end 4 and a distal end 5, the distal end 5 being provided with a locking assembly, the locking assembly comprising a fixing frame 6 and a tube sleeve 7, the fixing frame 6 being provided with a first through hole (not shown in the figure), one end of the suction tube 2 passing through the first through hole and connected with the tube sleeve 7, the tongue depressor 3 being arranged on the lower circumference of the suction tube 2 near the distal end 5, and the tongue depressor 3 being elastic.

[0029] Specifically, a fixing frame 6 is installed at the distal end 5 of the laryngoscope blade 1, and one end of the suction tube 2 passes through the first through hole on the fixing frame 6, and matching internal and external threads can be set at one end of the sleeve 7 and the suction tube 2, and the two are tightened by threaded connection, or the suction tube 2 can be firmly adhered to the tube sleeve 7 by bonding. A tongue depressor 3 with a certain elasticity is also bonded to the lower circumference of the suction tube 2 near the distal end 5 of the laryngoscope blade 1. The tongue depressor 3 can curl up when there is no force. In this way, when performing a laryngoscope operation, the distal end 5 of the laryngoscope blade 1 is first inserted into the patient's mouth, and at the same time, the suction tube 2 near the proximal end 4 of the laryngoscope blade 1 is tightened to make the tongue depressor 3 in a flat state. When encountering a patient who cannot expose the epiglottis normally, the doctor can loosen the suction tube 2. At this time, the tongue depressor 3 will restore its deformation and curl upward, thereby lifting the soft tissue of the tongue root above the epiglottis, and then fully exposing the glottis. The operation process is quite simple.

[0030] As an optional implementation, in some embodiments, a guide groove 8 is further included, and the guide groove 8 is arranged in the middle of the laryngoscope blade 1, and the suction tube 2 is placed on the guide groove 8. Among them, installing the guide groove 8 in the middle of the laryngoscope blade 1 can facilitate pulling the suction tube 2 and prevent the suction tube 2 from deviating, thereby improving the stability of the device.

[0031] In the above embodiment, further, the guide groove 8 is a U-shaped groove that matches the shape of the suction tube 2. The shape of the U-shaped groove is more closely matched with the cylindrical suction tube 2, and at the same time, the two inner walls of the U-shaped groove can also play a certain positioning effect, further improving the stability of the device.

[0032] As an optional implementation, in some embodiments, a plurality of second through holes 9 are formed in the circumferential direction of the suction tube 2 close to the tongue depressor 3 .

[0033] Specifically, during laryngoscopic surgery, patients with a lot of oral secretions are often encountered, which will seriously affect the doctor's field of vision. Therefore, a number of second through holes 9 are opened on the suction tube 2 near the tongue depressor 3 to drain oral secretions into the tube, thereby improving the clarity of the laryngoscope blade 1 and further improving the success rate of the operation.

[0034] As an optional implementation, in some embodiments, a pull ring 10 is provided at one end of the suction tube 2 away from the tongue depressor 3. The installation of the pull ring 10 can facilitate the doctor to tighten the pull ring 10 with his fingers to pull the suction tube 2, thereby preventing the suction tube 2 from accidentally loosening and causing the tongue depressor 3 to tilt upward, thereby affecting the performance of the operation.

[0035] As an optional implementation, in some embodiments, the suction tube 2 is integrally formed with the tongue depressor 3. The suction tube 2 and the tongue depressor 3 can be formed at one time by an injection molding machine, which is low in cost and will not fall off due to unstable bonding, thereby improving safety in use.

[0036] As an optional implementation, in some embodiments, the tongue depressor 3 is made of synthetic rubber or thermoplastic polyurethane elastomer rubber. The hardness of these two materials is moderate, and the tongue depressor 3 will not be unable to be lifted due to being too soft, nor will it be too hard to damage the patient's mucosa.

[0037] As an optional implementation, in some embodiments, the material of the tube sleeve 7 is plastic. For example, one of polyvinyl chloride (PVC), polystyrene (PS), and polypropylene (PP) can be selected, all of which have the advantages of meeting medical conditions and low cost.

[0038] Instructions for use: First, pass the end of the suction tube 2 bonded with the tongue depressor 3 through the first through hole of the fixing frame 6 and fix it with the tube sleeve 7 so that the suction tube 2 will not be separated from the fixing frame 6 when pulled; then, pull the pull ring 10 of the suction tube 2 to make the tongue depressor 3 in a flat state; finally, extend the distal end 5 of the laryngoscope blade 1 into the patient's oral cavity. If the patient's epiglottis cannot open normally, at this time, release the suction tube 2 to make the tongue depressor 3 tilt upward, thereby lifting up the soft tissue of the tongue root above the patient's epiglottis and fully exposing the glottis.

[0039] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.
