Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a laryngoscope blade assembly which can be used as a dental pad. Background Art

[0002] Endotracheal intubation is currently the most basic treatment and emergency means required to maintain the patient's unobstructed breathing. It is widely used in clinical anesthesia, establishment of respiratory passages, emergency resuscitation, pre-hospital rescue of critically ill patients and other clinical practices. Traditional endotracheal intubation technology requires the use of a laryngoscope. The laryngoscope blade is inserted into the patient's mouth and placed along the tissue surface until it reaches the epiglottic ligament. The laryngoscope blade is lifted to open the epiglottis and expose the glottis, and then the endotracheal tube is inserted into the trachea through the glottis to an appropriate length.

[0003] Video laryngoscope is the most commonly used tool for endotracheal intubation in clinical practice. The current mainstream video laryngoscope uses a disposable laryngoscope blade that is discarded after use. After the endotracheal tube is in place, the laryngoscope needs to be withdrawn and a dental pad needs to be placed between the patient's upper and lower incisors to protect and fix the endotracheal tube. However, there are often great safety hazards in the process of laryngoscope removal and dental pad placement, such as the endotracheal tube position changes, the endotracheal tube is withdrawn or inserted too deeply, the patient bites the tube, resulting in ventilation failure and damage to the endotracheal tube, etc. In addition, some clinical operations that require special postures such as prone position, lateral position, etc., or longer operation times often result in endotracheal tube dislocation. At this time, time is often tight, and the dental pad needs to be taken out and a new laryngoscope blade needs to be used for endotracheal intubation, which brings great risks to clinical work.

[0004] Some patents of medical three-way stopcocks are disclosed in the prior art, among which the utility model patent with announcement number CN214906649U discloses a laryngoscope blade with a tooth pad, including an arc-shaped lens body, one end of the lens body is provided with a plug slot for inserting a video laryngoscope, the other end is provided with a tongue support plate for supporting the tongue, and the side wall of the lens body is detachably provided with a tooth pad. Although the tooth pad can be put into the patient's mouth when the laryngoscope blade is put into the patient's mouth, the problem of the catheter being bitten due to the medical staff forgetting to put the tooth pad into the patient's mouth is solved, and the whole operation process is smoother and the efficiency is improved to a certain extent, but in fact, when the tooth pad is set on the side of the laryngoscope, the patient's mouth needs to be stretched very large when using it, which brings discomfort to the patient's pharynx and there are problems such as cumbersome use steps.

[0005] In view of this, the inventor conducted in-depth research on how to use the laryngoscope blade directly as a bite block after intubation is completed, and to simplify clinical operations to ensure the safety of clinical work, which led to the present case. Utility Model Content

[0006] In order to overcome the problem that a tooth pad is provided on the side of the laryngoscope blade in the prior art, which requires the patient's mouth to be stretched wide when using the laryngoscope, causing discomfort to the patient's pharynx, and has a relatively complex structure and cumbersome use steps, the utility model provides a laryngoscope blade assembly that can be used as a tooth pad, comprising an arc-shaped support column and a laryngoscope blade body sleeved on the support column, the laryngoscope blade body comprising a first laryngoscope blade and a second laryngoscope blade, the first laryngoscope blade is in contact with the second laryngoscope blade, and one end of the support column is detachably connected with a handle;

Both ends of the second laryngoscope blade are open. The second laryngoscope blade passes through the first laryngoscope blade and is sleeved on the support column near the handle. The second laryngoscope blade covers the edge of the outer wall of the open end of the first laryngoscope blade.

[0008] The laryngoscope blade is divided into two parts, the first laryngoscope blade and the second laryngoscope blade to form a simple structure. When in use, the first laryngoscope blade and the second laryngoscope blade are mounted on the support column to complete the preparation of the laryngoscope blade. The first laryngoscope blade and the second laryngoscope blade are in contact connection. When the patient is intubated during laryngoscopy, the support column and the first laryngoscope blade mounted on the front end of the support column are withdrawn from the patient's throat together, and the second laryngoscope blade can be retained in the patient's mouth to serve as a dental pad to assist in subsequent treatment, eliminating the process of placing a dental pad in the mouth after laryngoscopy, preventing the endotracheal tube from moving in the mouth and causing damage to the inner wall of the mouth and preventing the endotracheal tube from being bitten flat by the patient, and also avoiding the risk of secondary contamination of the oral cavity. The overall structure is simple, easy to use, and the use of a dental pad is avoided, saving medical costs.

[0009] Furthermore, limiting grooves are provided at the middle of two opposite end surfaces at the inner wall edge of the opening end of the first laryngoscope blade, and limiting pieces are provided on the support column corresponding to the limiting grooves, and the limiting grooves are clamped with the limiting pieces.

[0011] Furthermore, a first sealing ring is provided on the outer wall edge of the first laryngoscope blade covered by the second laryngoscope blade, and a second sealing ring is provided on the inner wall of the second laryngoscope blade offset to correspond to the first sealing ring, and the first sealing ring contacts and abuts against the second sealing ring.

[0012] Through the above technical scheme, the first sealing ring and the second sealing ring are staggered and arranged correspondingly at the edge of the outer wall where the first laryngoscope blade is covered by the second laryngoscope blade. After the first laryngoscope blade is mounted on the support column and fixed, the second laryngoscope blade passes through the first laryngoscope blade and is fixed on the support column. The gap between the second laryngoscope blade and the first laryngoscope blade is blocked by the mutual contact and connection of the two sealing rings, thereby preventing liquid from entering the gap and contaminating the support column during the laryngoscope process, and further avoiding pollution to the environment after being pulled out.

[0013] Furthermore, the limiting member includes a limiting plate movably connected to the support column, and a clamping block and a movable block are coaxially arranged on the side of the limiting plate facing away from the support column, the clamping block is arranged close to the free end of the support column, the clamping block is clamped with the limiting groove, and a limiting spring is arranged on the side of the limiting plate close to the support column, one end of the limiting spring is fixedly connected to the limiting plate, and the other end is fixedly connected to the support column.

[0014] Through the above technical solution, a limiting plate connected to the clamping block and the movable block is arranged on the support column. When in use, the clamping block and the limiting groove are adjusted by pressing the limiting spring under the movable block, which facilitates the installation and removal of the first laryngoscope blade on the support column and improves the practicality of the laryngoscope blade.

[0015] Furthermore, an arc-shaped tongue depressor is fixedly provided at the closed end of the first laryngoscope blade, the tongue depressor is bent toward the center direction of the arc, and a tongue depressing protrusion is provided on the front upper surface of the tongue depressor.

[0016] Furthermore, a buckle is arranged at one end of the second laryngoscope blade close to the handle, and a snap-fit ​​is arranged on the support column corresponding to the buckle, and the snap-fit ​​is snap-fitted with the buckle.

[0017] Furthermore, the arcuate concave surface on the outer side of the second laryngoscope blade extends a wing plate vertically to one side, the wing plate is flush with the arcuate concave surface of the second laryngoscope blade, and tooth-blocking plates are provided on both end surfaces of the outer wall of the second laryngoscope blade near one end of the handle opposite to the arcuate concave surface.

[0018] Furthermore, the second laryngoscope blade and the wing plate are integrally formed, and two corners of the wing plate away from the second laryngoscope blade are linearly processed.

[0019] Furthermore, a display device is connected to one end of the handle facing away from the support column, a camera is provided on the free end surface of the support column, and the camera is electrically connected to the display device.

[0020] Furthermore, the first laryngoscope blade, the second laryngoscope blade and the wing plate are all made of transparent materials.

[0021] Beneficial effects:
