Technical Field
[0001] The utility model relates to the technical field of medical devices, and particularly relates to an anti-fogging visual laryngoscope with a movable guide piece. Background Art
[0002] A visual laryngoscope is a new type of tracheal intubation auxiliary tool widely used in clinical practice in recent years. It consists of an illumination light source, a laryngeal lens, a lens handle, a camera battery, etc. It can transmit the collected images to a liquid crystal display screen in real time, clearly expose the epiglottis and surrounding tissue structures, monitor the tip of the tracheal catheter, reduce the irritation to the surrounding tissues of the larynx during intubation, reduce the stress response of the patient to tracheal intubation, improve the compliance and stability of tracheal intubation, and thus improve the success rate of tracheal intubation.
[0003] However, when the existing visual laryngoscope is used, usually a staff member holds the laryngoscope handle and drives the laryngeal blade into the patient's larynx to open the patient's larynx, and then inserts the catheter into the patient's larynx to achieve the purpose of intubation. However, the catheter is separated from the laryngeal blade. Medical staff need to control the laryngeal blade and pick up the catheter at the same time, and need to adjust the position of the catheter many times. The catheter cannot smoothly enter the patient's larynx. At the same time, hot air is generated in the patient's larynx. When the hot air contacts the camera in the laryngeal blade, fog will form on the surface of the camera, and the picture taken by the camera will become blurred, which will have a certain impact on the intubation of the patient's larynx. Therefore, an anti-fogging visual laryngoscope with a movable guide piece is provided. Summary of the Utility Model
[0004] The main purpose of the utility model is to provide an anti-fogging visual laryngoscope with a movable guide piece. By setting a guide piece, an electromagnetic block, a magnetic ring, a controller, a support rod, a fixing block, a fan, a fixing tube, a cavity, a through hole and a support plate, the utility model solves the problems that when the existing visual laryngoscope is used, it is inconvenient to defog the camera on the visual laryngoscope and it is inconvenient to perform intubation treatment on the patient's larynx.
[0005] The technical solution adopted by the present utility model to solve its technical problems is an anti-fogging visible laryngoscope with a movable guide piece, including a laryngoscope blade and a catheter. A laryngoscope handle for driving the movement of the laryngoscope blade is fixed by screws on one side of the laryngoscope blade. A camera for visualizing the patient's larynx is fixed by screws inside the laryngoscope blade. A guide piece for adjusting the position of the catheter is rotatably connected to the bottom of the laryngoscope blade. An electromagnetic block connected to the catheter is fixed by screws on the inner side of the guide piece. A magnetic ring connected to the electromagnetic block is sleeved outside the catheter. A controller for controlling the electromagnetic block is fixed by screws outside the laryngoscope handle. A fixing block for fixing the catheter is fixed by screws on one side of the laryngoscope handle. A support rod is inserted into one side of the fixing block, and a clamping block for clamping the catheter is welded to one side of the support rod. A support plate is fixed by screws on the outer side of the laryngoscope handle, and a fan is fixed by screws on one side of the support plate. A fixed pipe for conveying gas is fixed by screws on one side of the fan, and the end of the fixed pipe away from the fan extends into the laryngoscope blade. A cavity for storing gas is arranged inside the laryngoscope blade. Through holes for blowing air on the surface of the camera are formed on the surface of the cavity, and the number of the through holes is several.
[0006] By adopting the above technical solution, when a medical staff holds the laryngoscope handle, the laryngoscope blade on one side of the laryngoscope handle enters the patient's larynx. Then, the camera inside the laryngoscope blade takes pictures and displays the patient's larynx. At the same time, the fan outside the support plate allows external air to enter the fixed pipe. Subsequently, the gas enters the cavity inside the laryngoscope blade. Then, the multiple through holes formed on the cavity enable the gas to contact the surface of the camera, thereby preventing fog from forming on the surface of the camera and improving the clarity of the patient's larynx image.
[0007] When inserting a catheter into the patient's larynx, first pull the guide piece at the bottom of the laryngoscope blade to adjust the angle of the guide piece. Then, place the catheter outside the guide piece. Subsequently, the electromagnetic block on the guide piece is connected to the magnetic ring outside the catheter, causing the catheter to be adsorbed outside the guide piece. At the same time, pull the support rod outside the fixing block, and the support block drives the clamping block to move. Then, place the catheter into the fixing block, and the clamping block on the fixing block clamps the catheter, fixing the catheter at the bottom of the laryngoscope blade. After the laryngoscope blade is inserted into the patient's larynx, the controller outside the laryngoscope handle causes the electromagnetic block to lose magnetism, and the electromagnetic block is separated from the magnetic ring outside the catheter. Then, pull the clamping block on the support rod to move, and then remove the catheter from the fixing block. Then, pull the laryngoscope handle to remove the laryngoscope blade from the patient's larynx, leaving the catheter in the patient's larynx, thus facilitating the insertion of the catheter into the patient's larynx.
[0008] Specifically, a spring for resetting the support rod is sleeved outside the support rod.
[0009] By adopting the above technical solution, when the support rod drives the clamping block to move, the spring outside the support rod is compressed. When the external force is removed, the spring drives the support rod to move, and the support rod drives the clamping block to move, thus facilitating the resetting of the clamping block on the support rod.
[0010] Specifically, a clamp for fixing the fixing tube is sleeved outside the laryngoscope handle.
[0011] By adopting the above technical solution, the clamp outside the laryngoscope handle fixes the fixing tube, preventing the fixing tube from separating and scattering from the laryngoscope handle.
[0012] Specifically, rubber that contacts the catheter is bonded to the inner side of the clamping block.
[0013] By adopting the above technical solution, when the clamping block clamps the catheter, the rubber in the clamping block contacts the surface of the catheter, thus facilitating the protection of the catheter.
[0014] Specifically, a display screen for displaying the captured image of the camera is fixed to the top of the laryngoscope blade by screws.
[0015] By adopting the above technical solution, the display screen on the top of the laryngoscope blade displays the position of the patient's larynx, facilitating the intubation operation for medical staff.
[0016] Advantages of the present utility model:
[0017] (1) For a fog-proof visible laryngoscope with a movable guide piece according to the present utility model, when a medical staff holds the laryngoscope handle, the laryngoscope blade on one side of the laryngoscope handle enters the patient's larynx. Then, the camera inside the laryngoscope blade captures and displays the patient's larynx. At the same time, the fan outside the support plate allows external air to enter the fixing tube, and then the gas enters the cavity inside the laryngoscope blade. Subsequently, the multiple through holes opened on the cavity enable the gas to contact the surface of the camera, thereby preventing fog from forming on the surface of the camera and improving the clarity of the patient's larynx image.
[0018] (2) For a fog-proof visible laryngoscope with a movable guide piece according to the present utility model, when inserting a catheter into the patient's larynx, first pull the guide piece at the bottom of the laryngoscope blade to adjust the angle of the guide piece. Subsequently, place the catheter outside the guide piece. Then, the electromagnet on the guide piece connects with the magnetic ring outside the catheter, causing the catheter to be adsorbed outside the guide piece. At the same time, pull the rod outside the fixed block, and the support block drives the clamping block to move. Then, place the catheter into the fixed block, and the clamping block in the fixed block clamps the catheter, fixing the catheter at the bottom of the laryngoscope blade. After the laryngoscope blade is inserted into the patient's larynx, the controller outside the laryngoscope handle causes the electromagnet to lose magnetism, and the electromagnet separates from the magnetic ring outside the catheter. Then, pull the clamping block on the rod to move, and then remove the catheter from the fixed block. Then, pull the laryngoscope handle to remove the laryngoscope blade from the patient's larynx, leaving the catheter in the patient's larynx, thus facilitating the insertion of the catheter into the patient's larynx.
