Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to the technical field of laryngoscope blades.

Background Art

[0002] Laryngoscope blades are essential medical devices for laryngoscopy and some surgeries that require intubation through the throat. Since there are sometimes secretions such as phlegm in the throat, these secretions need to be cleared. Existing laryngoscope blades generally do not have the function of suctioning phlegm.

[0003] The existing patent CN204033304U discloses a laryngoscope blade with a phlegm suction function, which sucks phlegm by opening a channel on the main body of the laryngoscope blade and inserting a phlegm suction tube into the channel. Since the phlegm suction tube is not entirely located inside the channel and the phlegm suction tube is soft, the phenomenon that the phlegm suction tube blocks the light emitted by the laryngoscope is likely to occur during use, resulting in a worse field of view and a worse laryngoscope effect.

Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the existing technology, and propose a laryngoscope blade with a phlegm suction function, which can enable the laryngoscope blade to have the phlegm suction function and does not affect the illumination field of view of the laryngoscope.

[0005] To achieve the above purpose, the utility model proposes a laryngoscope blade with a phlegm suction function, which includes a laryngoscope blade main body, a tongue depressor, a rigid tube, a flexible tube, and a three-way joint. The laryngoscope blade main body includes a tongue depressor. A rigid tube is fixed on the tongue depressor. One end of the rigid tube is connected to a flexible tube, and the flexible tube is connected to a three-way joint. The three-way joint includes three ports, namely a first connection port, a second connection port, and a pressing port. The first connection port is used to connect to a negative pressure suction device, and the second connection port is connected to the flexible tube. The flexible tube and the three-way joint are located at the end of the laryngoscope blade main body far from the end entering the throat.

[0006] Preferably, the first connection port is a threaded interface, and the opening end of the pressing port is an arc surface.

[0007] Preferably, the rigid tube is fixed on the side of the tongue depressor far from the tongue pressing side, and the rigid tube is located outside the laryngoscope blade main body.

[0008] Preferably, the rigid tube extends from the end of the tongue depressor far from the end entering the throat to the front side of the end of the tongue depressor entering the throat.

[0009] Advantages of the present utility model: By arranging a rigid tube on the tongue depressor, secretions such as phlegm can be sucked away through the rigid tube, and the view of the laryngoscope will not be affected, which is relatively convenient to use; the setting of the pressing port enables the control of whether to perform sputum suction on the laryngeal lens by simply blocking the pressing port with the thumb, which can be controlled with one hand, is relatively convenient to control, and after being proficient in the operation, the suction force of sputum suction can be adjusted to a certain extent by the thumb according to experience.

[0010] The features and advantages of the present utility model will be described in detail through embodiments in conjunction with the accompanying drawings.

Explanation of the Drawings

[0011] Figure 1 is the front view of the laryngeal lens with sputum suction function of the present utility model;

[0012] Figure 2 is the partial side view of the laryngeal lens with sputum suction function of the present utility model.

[0013] In the figure: 1 - main body of the laryngeal lens, 2 - rigid tube, 3 - three-way joint, 10 - tongue depressor, 20 - flexible tube, 31 - first connection port, 32 - second connection port, 33 - pressing port.

Specific Embodiments

[0014] Refer to Figure 1 、 Figure 2 , the laryngeal lens with sputum suction function of the present utility model includes a main body 1 of the laryngeal lens, a tongue depressor 10, a rigid tube 2, a flexible tube 20, and a three-way joint 3. The main body 1 of the laryngeal lens includes a tongue depressor 10. A rigid tube 2 is fixed on the tongue depressor 10. One end of the rigid tube 2 is connected to a flexible tube 20, and the flexible tube 20 is connected to a three-way joint 3. The three-way joint 3 includes three ports, which are a first connection port 31, a second connection port 32, and a pressing port 33 respectively. The first connection port 31 is used to connect to a negative pressure aspirator, and the second connection port 32 is connected to the flexible tube 20. The flexible tube 20 and the three-way joint 3 are located at the end of the main body 1 of the laryngeal lens away from the end entering the larynx.

[0015] The first connection port 31 is a threaded interface, and the open end of the pressing port 33 is an arc surface.

[0016] The rigid tube 2 is fixed on the side of the tongue depressor 10 away from the tongue-pressing side, and the rigid tube 2 is located outside the main body 1 of the laryngeal lens.

[0017] The rigid tube 2 extends from the end of the tongue depressor 10 away from the end entering the larynx to the front side of the end of the tongue depressor 10 entering the larynx.

[0018] Working process of the present utility model:

[0019] During the operation of the laryngoscope blade with sputum suction function of the present utility model, the laryngoscope is installed on the laryngoscope blade body 1, the first connection port 31 is connected to the negative pressure suction device, and then the laryngoscope blade body 1 is extended to the larynx in the correct way. At this time, the thumb is not pressed on the pressing port 33, and the negative pressure suction device intakes air through the pressing port 33. When sputum suction is required, the thumb is used to block the pressing port 33. At this time, due to the blocking of the pressing port 33, under the action of the negative pressure suction device, a negative pressure is formed inside the hose 20 and the rigid tube 2, and the sputum will be sucked into the rigid tube 2 and finally sucked away by the negative pressure suction device.

[0020] The above embodiments are illustrative of the present utility model and not restrictive thereof. Any scheme obtained by simply transforming the present utility model falls within the protection scope of the present utility model.
