Suckable laryngoscope and control method thereof

Abstract

The invention provides a suckable laryngoscope which comprises a laryngoscope handle; a laryngoscopic lens, wherein a plurality of first suction holes are symmetrically formed in the two sides of thelaryngoscope lens, a plurality of second suction holes are formed in the bottom of one end, far away from the laryngoscope handle, of the laryngoscope lens; a pair of first suction tubes which is symmetrically arranged in the laryngoscope lens; a plurality of second suction tubes which are arranged in the laryngoscope lens, wherein one end of each second suction tube penetrates out of the corresponding second suction hole and is flush with the second suction hole, and the other end of each second suction tube is communicated with the other end of the corresponding first suction tube; a plurality of connecting tubes which are in one-to-one correspondence with the first suction holes, wherein one ends of the connecting tubes penetrate out of the corresponding first suction holes, and the other ends of the connecting pipes are communicated with the corresponding first suction tubes; a flow guide tube, wherein one end of the flow guide tube is arranged in the laryngoscope lens and is communicated with the other ends of the first suction tubes and the second suction tubes, and the other end of the flow guide tube is arranged in the laryngoscope handle; and an accommodating box which isarranged in the laryngoscope handle and is communicated with the other end of the flow guide tube. The invention further provides a control method of the suckable laryngoscope.

Description

technical field [0001] The present invention relates to the technical field of medical instruments, and more specifically, the present invention relates to an aspirable laryngoscope and a control method thereof. Background technique [0002] In clinical work, patients often experience excessive secretions during laryngoscopy, which requires the patient to cooperate with swallowing saliva to continue laryngoscopy. However, some patients have severe swallowing reflexes and cannot cooperate, which is often time-consuming and labor-intensive. Also increases the inspection time. [0003] Chinese invention patent 201710978337.3 discloses a flexible supporting laryngoscope electric knife head with a suction tube, including a knife head body, an insulating layer and a suction tube; The right ends all extend to the outside of the insulation layer, and the left end of the suction tube is connected with an external suction device port, through which the suction tube smokes and sucks b...

Problems solved by technology

However, this structure only has suction holes on the top of the light guide lens, which can only attract the secretions at this place, while the secretions at other positions cannot be treated, and the suction tube is flush with the suction port. And close to the suction port, the secretion can be effectively sucked, and when the amount of secretion does not reach the suction port, the observation field of view can still be unclear, but the suction tube cannot effectively attract the secretion
