Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, a visual inspection device includes a housing 100, a light source hole 110 and a slot 120 for inserting a tongue depressor are disposed at a front end of the housing. The housing is covered with a cover plate 200, which forms a mounting cavity with the housing, and a holding mechanism 300 capable of holding and fixing the tongue depressor inserted through the insertion slot and a light source mechanism 400 for irradiating the pharynx of the patient are mounted in the mounting cavity. It should be noted that the light source mechanism is triggered by the holding mechanism and emits light only when the tongue depressor is inserted into the tongue depressor of the present invention.

As a further improvement of the above embodiment, in order to prevent the tongue depressor from pushing against the light source mechanism after insertion and damaging the light source mechanism, a partition plate 130 is further provided in the housing to separate the holding mechanism from the light source mechanism.

As a further improvement of the above embodiment, the light source mechanism 400 mainly comprises a lamp bead 410 embedded in the light source hole and a battery 420 arranged in the housing, and a trigger switch 430 capable of controlling the conduction state between the lamp bead and the battery is arranged between the battery and the lamp bead. It should be noted that the trigger switch needs to be turned on when in a pressed state, and the pressed state is realized by inserting the tongue depressor into the clamping mechanism to change the shape of the clamping mechanism.

As a further improvement of the above embodiment, the battery has a function of repeating charge and discharge in order to reduce the use cost. Specifically, the battery is electrically connected to the charging module 440 to realize external power connection charging.

As a further modification of the above embodiment, the clamping mechanism 300 includes two elastic clamping plates 310, one end of the two elastic clamping plates near the slot is fixedly connected with the housing to form a trumpet-shaped access passage 320, and the caliber of the access passage is opposite to the slot and gradually decreases from one side near the slot to one side far away from the slot. The trigger switch is disposed between the elastic splint and the sidewall of the housing, when the tongue depressor is inserted into the access passage, the elastic splint is turned over toward the sidewall of the housing under the action of the tongue depressor to turn on the trigger switch 430, and when the tongue depressor is pulled out, the elastic splint returns to the initial state.

As a further improvement to the above embodiment, a return spring 330 is provided between the resilient clamp and the side wall of the housing to ensure that the clamping action is maintained after prolonged use of the resilient clamp.

As a further improvement of the above embodiment, in order to ensure the stability of the tongue depressor in use, restraining plates 340 extending in the longitudinal direction of the elastic splint are horizontally provided on the upper and lower edges of the elastic splint. It should be noted that the restraint plate is made of soft rubber so as to use tongue depressors with different specifications and different thicknesses.

As a further improvement of the above embodiment, in order to facilitate insertion of the tongue depressor, one end of the restraint plate near the insertion slot is provided with a lead-in slope 341.

As a further improvement of the above embodiment, in order to avoid cross infection caused by direct contact between the medical staff and the used tongue depressor, a chute 210 extending along the length direction of the inserted tongue depressor is formed on the cover plate, a slide block 500 is slidably disposed in the chute, and a push plate 510 capable of extending into the access passage is disposed on the lower surface of the slide block. After the tongue depressor is inserted into the access channel, the front end of the tongue depressor is supported on the push plate to push the sliding block connected with the push plate backwards, and after the tongue depressor is used, the sliding block is pushed to move forwards to enable the tongue depressor to exit the access channel. The structure can avoid the operation that medical care personnel directly pull out the used tongue depressor by hands, and avoid cross infection.

As a further improvement of the above embodiment, in order to allow contaminants to enter the chute, one sealing rubber sheet 600 covering the chute is provided on each side of the chute.
