Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of disposable laryngoscopes, in particular to a disposable electronic laryngoscope blade with an oxygen supply function. Background Art
[0002] Laryngoscope is a commonly used medical device, suitable for laryngeal exploration before tracheal intubation. However, existing laryngoscope technology has some defects. After anesthesia, the patient is given sedatives, analgesics and muscle relaxants, which causes the patient to experience apnea and no assisted ventilation during the tracheal intubation process. In this process, the doctor needs to quickly and accurately insert the tracheal tube, and then supply the patient with oxygen through the tracheal tube to maintain breathing.
[0003] However, when inserting a tracheal tube, the existing laryngoscope blades are not equipped with an oxygen supply structure, so that the patient is actually in a state of no breathing during the entire exploration process. Therefore, if the intubation process is not smooth, the patient will suffer from hypoxia, and taking too long may even cause cardiac arrest. The laryngoscope blade for observing the throat can only be used for 3-5 minutes. If it exceeds this time, the laryngoscope blade must be pulled out immediately, and oxygen supply equipment must be brought in for auxiliary oxygen supply, which undoubtedly increases the difficulty and complexity of the operation.
[0004] Therefore, there is an urgent need for a laryngoscope blade that can provide patients with a stable oxygen supply while inserting a tracheal tube to reduce the risk of hypoxia in patients during the operation. In view of this, we propose a disposable electronic laryngoscope blade with oxygen supply function. Utility Model Content
[0005] The purpose of the utility model is to provide a disposable electronic laryngoscope blade with an oxygen supply function to solve the problems raised in the above background technology.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A disposable electronic laryngoscope blade with oxygen supply function comprises a tongue depressor, wherein the front side of the bottom of the tongue depressor is provided with a blade channel for inserting an electronic laryngoscope, and a buckle cantilever is provided on the right side of the blade channel. When in use, the laryngoscope of the electronic laryngoscope is inserted into the blade channel, and the buckle cantilever is buckled on the video pestle of the electronic laryngoscope, so that the disposable electronic laryngoscope blade is connected to the electronic laryngoscope;
[0008] An intubation channel is provided at the bottom of the tongue depressor and at a position behind the lens channel, a partition is provided between the upper and lower sides of the inner wall of the intubation channel, and the intubation channel is divided into an oxygen supply channel and a tracheal tube channel through which the tracheal tube passes by the partition, and an adjustable oxygen supply capillary is provided in the oxygen supply channel;
[0009] When in use, in order to prevent the patient from suffocating, the staff will pass one end of the oxygen supply tube through the oxygen supply channel until it is inserted into the patient's throat, and then connect the other end of the oxygen supply tube to an external oxygen supply device to supply oxygen to the patient. The staff will then pass the tracheal tube equipped with a tracheal tube shaper through the tracheal tube channel and continue to move it until the end of the tracheal tube reaches the glottis. After the end of the tracheal tube reaches the glottis, the staff will keep the tracheal tube in place at the glottis, and then the assistant will assist in removing the tracheal tube shaper from the tracheal tube. The staff will then continue to insert the tracheal tube into the trachea to an appropriate depth. After completing the tracheal tube insertion operation, the staff will remove the disposable electronic laryngoscope blade from the patient's mouth and separate it from the electronic laryngoscope. When the operation is completed, the disposable electronic laryngoscope blade will be removed from the oxygen supply tube and tracheal tube and discarded.
[0010] Preferably, the tongue depressor, lens channel and cannula channel are all made of polycarbonate material, which is transparent and safe. The tongue depressor, lens channel and cannula channel are an integrated structure, which maintains integrity and is easy to use.
[0011] Preferably, the right end of the lens channel and the right end of the tongue depressor are located on the same plane, the left end of the tongue depressor protrudes from the left end of the intubation channel, the left end of the intubation channel protrudes from the left end of the lens channel, so as to prevent the lens channel and the intubation channel from releasing the patient's tongue, and the right end of the intubation channel protrudes from the right end of the lens channel, so as to facilitate the staff to insert the oxygen supply tube and the endotracheal tube into the oxygen supply channel and the endotracheal tube channel respectively.
[0012] Preferably, both front and rear ends of the left side of the tongue depressor are rounded structures to avoid poking the patient's mouth.
[0013] Preferably, the bottoms of the left ends of the lens channel and the cannula channel are both rounded structures to avoid piercing the patient's oral cavity.
[0014] Preferably, the oxygen supply channel is located in front of the endotracheal tube channel, and the cavity volume of the oxygen supply channel is smaller than the cavity volume of the endotracheal tube channel. When the endotracheal tube is inserted, the oxygen supply tube plays a role of auxiliary oxygen supply, and a very thick oxygen supply tube is not required, thereby avoiding the volume of the intubation channel being too large to affect the use.
[0015] Preferably, a rubber seal is provided at the right end of the oxygen supply channel, and a circular hole is opened on the top of the rubber seal. The outer wall of the oxygen supply tube fits tightly with the inner wall of the circular hole, which is conducive to fixing the position of the oxygen supply tube, thereby facilitating the staff to adjust the position of the oxygen supply tube so that the end of the oxygen supply tube can be fixed in place after being inserted into the patient's throat.

[0027] See also Figure 1-Figure 4 , the utility model provides a technical solution:
[0028] A disposable electronic laryngoscope blade with oxygen supply function comprises a tongue depressor 1. A blade channel 2 for inserting an electronic laryngoscope is provided on the front side of the bottom of the tongue depressor 1. A buckle cantilever 4 is provided on the right side of the blade channel 2. When in use, the laryngoscope of the electronic laryngoscope is inserted into the blade channel 2, and the buckle cantilever 4 is buckled on the video pestle of the electronic laryngoscope, so that the disposable electronic laryngoscope blade is connected to the electronic laryngoscope.
[0029] An intubation channel 3 is provided at the bottom of the tongue depressor 1 and at the rear side of the lens channel 2. A partition 30 is provided between the upper and lower sides of the inner wall of the intubation channel 3. The intubation channel 3 is divided into an oxygen supply channel 31 and an endotracheal tube channel 32 through which an endotracheal tube 6 passes through by the partition 30. An adjustable oxygen supply capillary 5 is provided in the oxygen supply channel 31.
[0030] During use, in order to prevent the patient from suffocating, the staff passes one end of the oxygen supply tube 5 through the oxygen supply channel 31 until it is inserted into the patient's throat, and then connects the other end of the oxygen supply tube 5 to an external oxygen supply device to supply oxygen to the patient. Then the staff passes the tracheal tube 6 equipped with a tracheal tube shaper through the tracheal tube channel 32 and continues to move until the end of the tracheal tube 6 reaches the glottis. After the end of the tracheal tube 6 reaches the glottis, the staff keeps the tracheal tube 6 in the position of the glottis, and then the assistant assists in removing the tracheal tube shaper from the tracheal tube 6. Then the staff continues to insert the tracheal tube 6 into the trachea to an appropriate depth. After completing the insertion of the tracheal tube 6, the staff removes the disposable electronic laryngoscope blade from the patient's mouth and separates it from the electronic laryngoscope. When the operation is completed, the disposable electronic laryngoscope blade is removed from the oxygen supply tube 5 and the tracheal tube 6 and discarded.
[0031] In this embodiment, the tongue depressor 1, the lens channel 2 and the insertion channel 3 are all made of polycarbonate material, which is transparent and safe. The tongue depressor 1, the lens channel 2 and the insertion channel 3 are an integrated structure, which maintains integrity and is easy to use.
[0032] Specifically, the right end of the lens channel 2 and the right end of the tongue depressor 1 are located on the same plane, the left end of the tongue depressor 1 protrudes from the left end of the intubation channel 3, and the left end of the intubation channel 3 protrudes from the left end of the lens channel 2, so as to prevent the lens channel 2 and the intubation channel 3 from releasing the patient's tongue, and the right end of the intubation channel 3 protrudes from the right end of the lens channel 2, so as to facilitate the staff to insert the oxygen supply tube 5 and the endotracheal tube 6 into the oxygen supply channel 31 and the endotracheal tube channel 32 respectively.
[0033] Furthermore, both the front and rear ends of the left side of the tongue depressor 1 are rounded structures to avoid poking the patient's mouth.
[0034] Furthermore, the bottoms of the left ends of the lens channel 2 and the cannula channel 3 are both rounded structures to avoid piercing the patient's oral cavity.
[0035] Furthermore, the oxygen supply channel 31 is located in front of the tracheal tube channel 32, and the cavity volume of the oxygen supply channel 31 is smaller than the cavity volume of the tracheal tube channel 32. When the tracheal tube 6 is inserted, the oxygen supply tube 5 plays a role of auxiliary oxygen supply, and a very thick oxygen supply tube is not required, thereby avoiding the volume of the intubation channel 3 being too large to affect the use.
[0036] Furthermore, a rubber seal 7 is provided at the right end of the oxygen supply channel 31, and a circular hole 70 is opened on the top of the rubber seal 7. The outer wall of the oxygen supply tube 5 fits tightly with the inner wall of the circular hole 70, which is conducive to fixing the position of the oxygen supply tube 5, thereby facilitating the staff to adjust the position of the oxygen supply tube 5 so that the end of the oxygen supply tube 5 can be fixed in place after being inserted into the patient's throat.
[0037] When the disposable electronic laryngoscope blade with oxygen supply function of this embodiment is in use, the staff inserts the laryngoscope of the electronic laryngoscope into the blade channel 2, and makes the buckle cantilever 4 snap onto the video pestle of the electronic laryngoscope to connect the disposable electronic laryngoscope blade to the electronic laryngoscope.
