Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable laryngoscope blade capable of achieving tracheal intubation and continuous oxygen supply at the same time. Background Art

[0002] Traditional direct laryngoscopy-assisted and video laryngoscopy-assisted tracheal intubation have significant advantages. However, they also share a disadvantage: the inability to administer oxygen simultaneously with intubation. This disadvantage often forces the intubator to abandon the intubation attempt due to a drop in blood oxygen saturation during intubation when faced with a difficult airway or when the patient's oxygen reserve is poor. The laryngoscope and tracheal tube are removed, and mask ventilation is reinstituted, requiring further intubation after oxygen reserves are restored. This process not only increases the psychological pressure on the intubating physician, but more importantly, repeated intubation attempts significantly increase the incidence of intubation-related complications.

[0003] Based on the above background, some people have invented laryngoscope blades that can provide oxygen, but there are still some shortcomings. CN215838959U is based on the traditional disposable laryngoscope blade and adds an oxygen supply pipeline in the right-angle space. This design solves the problem of continuous oxygen supply during intubation in the simplest and most intuitive way. However, this right-angle space is also the intubation channel required for placing the tracheal tube. There is no doubt that this newly added oxygen supply pipeline will occupy part of the intubation channel space, increasing the difficulty of placing the tracheal tube, and increasing the adverse effects such as prolonged intubation time. The one-way three-connection joint on the oxygen supply pipeline occupies too much volume, such as Figure 1 As shown, conventional disposable laryngoscope blades are tightly connected to the laryngoscope. If this three-way connector is present, the blade and laryngoscope will not fit together properly. The additional oxygen delivery tube occupies an increased volume within the oral cavity, which undoubtedly introduces inconvenience during intubation. Utility Model Content

[0004] The purpose of the utility model is to provide a disposable laryngoscope blade that can realize tracheal intubation and continuous oxygen supply at the same time, so as to solve the problems raised in the above background technology.

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The following is combined with Figure 2 And specific embodiments, the utility model is discussed in detail:

[0026] It should be noted that the "proximal end" in the above description and the following description usually refers to the end of the medical device close to the operator during normal operation, and the "distal end" usually refers to the end of the medical device that first enters the patient's body during normal operation.

[0027] like Figure 2 As shown, the utility model provides a disposable laryngoscope blade that can achieve tracheal intubation and continuous oxygen supply at the same time, which is mainly used for intubation and includes:

[0028] A laryngoscope blade mounting member 3, which is in the shape of an elongated strip and matches the shape of the laryngoscope blade;

[0029] A tongue depressor 2 is provided on one side of the laryngoscope blade mounting member 3, and the upper surface of the tongue depressor 2 is higher than the upper surface of the laryngoscope blade mounting member 3, and the two form a specific right-angle space; an air delivery channel is provided inside the tongue depressor 2 for functions such as delivering oxygen;

[0030] The injection tube 4 is closely arranged beside the distal end of the tongue depressor 2, located in a right-angle space, and located on the upper surface of the laryngoscope blade mounting member 3; the injection tube 4 has an inlet and an outlet, the inlet of the injection tube 4 is connected to the output port of the air supply channel in the tongue depressor 2, and the injection tube outlet 6 is opposite to the human glottis to achieve precise injection.

[0031] Furthermore, the laryngoscope blade mounting piece 3 is arc-shaped, and the width of the laryngoscope blade mounting piece 3 gradually decreases from the proximal end to the distal end, so that the laryngoscope blade can assist the laryngoscope blade in inserting into the throat for viewing.

[0032] Furthermore, the tongue depressor 2 is in the shape of an arc-shaped long strip, and the distal end of the tongue depressor 2 is bent upward, which conforms to the structure of the human throat space and is easy to insert into the throat.

[0033] Furthermore, a buckle 7 is provided at the proximal end of the tongue depressor 2 for fixing the tight connection between the laryngoscope and the laryngoscope blade; it should be noted that the specific structure of the buckle 7 is not limited in the present invention and can be designed by those skilled in the art based on common sense, as long as the locking and fixing function can be achieved.

[0034] Furthermore, a connector 1 is provided at the proximal end of the tongue depressor 2. The connector 1 is connected to the input port of the air supply channel of the tongue depressor 2, and is used to tightly connect the air supply channel and the air supply device to ensure good airtightness. Specifically, the connector 1 is used to connect to the high-flow oxygen supply device of the anesthesia machine. The high-flow oxygen supply device of the anesthesia machine is a prior art and must be used before the intubation operation. The high-flow oxygen supply device of the anesthesia machine can be directly connected to the laryngoscope blade during the intubation process, making the operation more convenient.

[0035] Furthermore, the laryngoscope blade mounting member 3, the tongue depressor 2 and the ejection tube 4 are integrally formed, the entire laryngoscope blade structure is manufactured at one time using a mold, and the arrangement of the various components is a one-time integral structure, which optimizes the design and process flow.

[0036] Furthermore, a first through hole is provided on the side of the distal end of the tongue depressor 2, which serves as the output port of the tongue depressor 2; a second through hole is provided on the side of the injection tube 4 close to the tongue depressor 2, which serves as the inlet of the injection tube 4; the output port of the tongue depressor 2 is connected to the inlet of the injection tube 4, so that the air supply channel in the tongue depressor 2 is connected to the injection tube 4; the integrated connection between the two has good air tightness and saves design space; the proximal port 5 of the injection tube is closed, and the injection tube outlet 6 is provided at the distal end.

[0037] Furthermore, the diameter of the injection pipe 4 is 3 mm to 4 mm. A smaller diameter can reduce the volume occupied.

[0038] Furthermore, the injection tube 4 is a quarter cylinder, which has a certain structural beauty. Compared with a circle and a square of the same area, the circumference of a circle is smaller, so the side area of a cylinder is smaller than that of a cuboid with a square side, which saves materials to a certain extent, effectively utilizes the angular space, and is more convenient for intubation operation.

[0039] During the entire intubation process, the embodiment of the present invention is used. After the patient is anesthetized using an anesthesia machine, the laryngoscope blade of the embodiment is connected to the laryngoscope. The laryngoscope is inserted from the entrance of the laryngoscope blade mounting member 3 until the buckle 7 is locked. The connecting joint 1 is sealed with the high-flow oxygen supply device of the anesthesia machine. After the above steps are completed, the laryngoscope blade of the embodiment is placed inside the patient's mouth. The left side of the tongue depressor 2 is in contact with the tongue root in the mouth. The laryngoscope is slowly inserted into the throat and slowly advanced along the midline of the tongue surface to the epiglottis. After the epiglottis is visible through the laryngoscope, the laryngoscope blade is advanced to the epiglottis root and the laryngoscope is gently lifted to expose the glottis structure. The jet tube outlet 6 is accurately pointed at the glottis, and the patient's throat is clearly visible. At this time, oxygen is input from the connecting joint 1 and ejected from the jet tube outlet 6 into the patient's throat, ensuring that the patient is adequately oxygenated and facilitating subsequent intubation.

[0040] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely optional examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
