Description

Technical Field

[0001] The utility model relates to the technical field of throat medical equipment, in particular to a visual laryngoscope for tracheal intubation. Background Art

[0002] Since the larynx is located deep and has a complex physiological structure, it cannot be directly viewed. Medical examinations of the larynx often require the use of a laryngoscope. A laryngoscope can provide a detailed understanding of the abnormalities in the laryngeal structure, identify the location and extent of the lesion, and perform a biopsy on the diseased tissue when necessary. With the development of modern medicine and technology, video laryngoscopes with displays have been more widely used because they can more clearly display the local anatomical structure of the pharynx. The emergence of video laryngoscopes has greatly reduced the chances of difficulty in glottic exposure, increased the success rate of tracheal intubation, and reduced airway damage and difficult airway-related mortality, demonstrating the impact of scientific and technological progress on human health.

[0003] At present, when medical staff use a video laryngoscope to explore the patient's oral observation area, a large amount of respiratory secretions will be secreted in the mouth due to the patient's tension and other conditions. The large amount of respiratory secretions produced in the mouth will adhere to the transparent mirror of the video laryngoscope that is inserted into the patient's throat, thereby causing blurred vision on the transparent mirror and affecting the exploration probe on the video laryngoscope for filming and observation. In order to solve this problem, the present device provides a video laryngoscope for endotracheal intubation. Utility Model Content

[0004] The purpose of the utility model is to provide a visual laryngoscope for endotracheal intubation in view of the deficiencies of the prior art, so as to solve the above-mentioned technical problems.

[0005] The embodiment of the utility model adopts the following technical scheme: it includes a visual laryngoscope for observing the oral and pharyngeal areas of a patient, a respiratory secretion scraping mechanism for the visual laryngoscope observation area, and a respiratory secretion suction mechanism for the visual laryngoscope observation area, the respiratory secretion scraping mechanism is arranged at the exploration probe on the visual laryngoscope for exploration, the exploration probe is covered by a transparent mirror, and the respiratory secretion suction mechanism is arranged at the exploration area on the visual laryngoscope and is located next to the respiratory secretion scraping mechanism.

[0006] Furthermore, the respiratory secretion scraping mechanism includes a scraping member, a connecting member and a pushing member. A scraping groove is provided at the exploration probe on the video laryngoscope for exploration. The scraping member is arranged in the scraping groove and is slidably fitted. A limiting groove is provided in the middle part of the video laryngoscope. The pushing member is arranged in the limiting groove and is lockable and slidably fitted. The pushing member and the scraping member are connected by a connecting member.

[0007] Furthermore, the connecting piece has a certain toughness and can be bent at a certain angle in coordination with the video laryngoscope.

[0008] Furthermore, the respiratory secretion suction mechanism is a respiratory secretion suction tube, the side of the scraping groove is connected to a respiratory secretion storage groove, and the respiratory secretion suction tube is a hose and is connected to the respiratory secretion storage groove.

[0009] Furthermore, the end of the respiratory secretion suction tube can be connected to the respiratory secretion suction port of the respiratory secretion suction device and the two are in a matching state.

[0010] At least one of the above technical solutions adopted in the embodiment of the utility model can achieve the following beneficial effects:

[0011] When the medical staff uses the visual laryngoscope to explore the desired oral observation part of the patient, they first hold the visual laryngoscope and extend the exploration end of the visual laryngoscope into the desired position in the patient's oral cavity for exploration. Then, during the exploration process, the respiratory secretions in the patient's oral cavity adhere to the transparent mirror, affecting the exploration line of sight. The medical staff then moves the pusher to the other side, so that the movement of the pusher drives the connecting member to move. After the movement of the connecting member, the scraping member is driven to move on the surface of the transparent mirror, so as to scrape off the respiratory secretions adhered to the transparent mirror, thereby avoiding the transparent mirror adhering to the respiratory secretions, causing the line of sight of the exploration probe to be blurred and thus affecting the observation.

[0012] The push member is moved in the limit groove to drive the scraping member on the transparent mirror. After the respiratory secretions on the transparent mirror are scraped, the respiratory secretions are squeezed and pushed to flow into the respiratory secretion storage groove. In order to prevent the respiratory secretions on the transparent mirror from flowing into the patient's oral cavity and throat after being scraped, causing the patient to be nervous and nauseous, the respiratory secretion absorber is immediately started after the respiratory secretions are scraped, and the respiratory secretions flowing into the respiratory secretion storage groove after scraping are sucked out through the respiratory secretion absorption tube;

[0013] The invention realizes that after the respiratory secretions in the patient's mouth adhere to the transparent mirror, the respiratory secretions on the transparent mirror can be scraped off by pushing the respiratory secretion scraping mechanism. At the same time, the traditional respiratory secretion absorber can be connected to the respiratory secretion absorber to suck out the scraped respiratory secretions, thereby avoiding the respiratory secretions generated inside the patient's mouth causing the detection line of sight of the exploration probe to be blurred and thus affecting the observation effect.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by patients with ordinary skills in the field without making creative work are within the scope of protection of the utility model.

[0024] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] The embodiment of the utility model provides a visual laryngoscope for endotracheal intubation, comprising a visual laryngoscope 1 for observing the oral cavity and pharynx of a patient, a respiratory secretion scraping mechanism 2 for the observation site of the visual laryngoscope 1, and a respiratory secretion suction mechanism 3 for the observation site of the visual laryngoscope 1, wherein the respiratory secretion scraping mechanism 2 is arranged at a probing probe 11 for probing on the visual laryngoscope 1, and the probing probe 11 is covered by a transparent mirror 12, and the respiratory secretion suction mechanism 3 is arranged at the probing site of the visual laryngoscope 1 and is located beside the respiratory secretion scraping mechanism 2;

[0026] When medical staff use the visual laryngoscope 1 to explore the patient's desired oral observation area, the respiratory secretions in the patient's mouth will adhere to the transparent mirror 12, causing the detection line of sight of the detection probe 11 to be blurred and thus affecting its observation. After the respiratory secretions in the patient's mouth adhere to the transparent mirror 12, the device can scrape the respiratory secretions on the transparent mirror 12 by pushing the respiratory secretion scraping mechanism 2. At the same time, the traditional respiratory secretion extractor can be connected to the respiratory secretion suction mechanism 3 to suck out the scraped respiratory secretions, thereby avoiding the respiratory secretions generated inside the patient's mouth causing the detection line of sight of the detection probe 11 to be blurred and thus affecting its observation effect.

[0027] In a further preferred embodiment of the utility model, the respiratory secretion scraping mechanism 2 includes a scraping member 21, a connecting member 22 and a pushing member 23. The exploration probe 11 on the video laryngoscope 1 for exploration is provided with a scraping groove 24. The scraping member 21 is arranged in the scraping groove 24 and is slidably matched. A limiting groove 13 is provided in the middle of the video laryngoscope 1. The pushing member 23 is arranged in the limiting groove 13 and is lockable and slidably matched. The pushing member 23 and the scraping member 21 are connected by the connecting member 22;

[0028] When the medical staff uses the visual laryngoscope 1 to explore the desired oral observation area of ​​the patient, they first hold the visual laryngoscope 1 and extend the exploration end of the visual laryngoscope 1 into the desired position in the patient's mouth for exploration. Then, during the exploration process, the respiratory secretions inside the patient's mouth adhere to the transparent mirror 12, affecting their exploration line of sight. The medical staff then moves the pushing member 23 inward to the other side, so that the movement of the pushing member 23 drives the connecting member 22 to move. After the connecting member 22 moves, it drives the scraping member 21 to move on the surface of the transparent mirror 12, thereby scraping off the respiratory secretions adhered to the transparent mirror 12, avoiding the transparent mirror 12 from adhering to the respiratory secretions, causing the line of sight of the exploration probe 11 to be blurred and thus affecting its observation.

[0029] In a further preferred embodiment of the present invention, the connecting member 22 has a certain toughness and can be bent at a certain angle in coordination with the video laryngoscope 1;

[0030] Since the connecting piece 22 has a certain toughness and can be bent at a certain angle with the visual laryngoscope 1, medical staff can cooperate with the visual laryngoscope 1 during the exploration process, thereby avoiding affecting the normal exploration of the visual laryngoscope 1. At the same time, the connecting piece 22 can drive the scraper 21 to move to scrape respiratory secretions.

[0031] In a further preferred embodiment of the utility model, the respiratory secretion suction mechanism 3 is a respiratory secretion suction tube 31, and the side of the scraping groove 24 is connected to the respiratory secretion storage groove 25, and the respiratory secretion suction tube 31 is a hose and is connected to the respiratory secretion storage groove 25;

[0032] The push member 23 is moved in the limiting groove 13 to drive the scraping member 21 on the transparent mirror 12. After the respiratory secretions on the transparent mirror 12 are scraped, the respiratory secretions are squeezed and pushed to flow into the respiratory secretion storage groove 25. In order to prevent the respiratory secretions on the transparent mirror 12 from flowing into the patient's mouth and throat after being scraped, causing the patient to be nervous and nauseous, the respiratory secretion absorber is immediately started after the respiratory secretions are scraped, and the respiratory secretions that flow into the respiratory secretion storage groove 25 after scraping are sucked out through the respiratory secretion absorption tube 31.

[0033] In a further preferred embodiment of the utility model, the end of the respiratory secretion suction tube 31 can be connected to the respiratory secretion suction port of the respiratory secretion suction device and the two are in an adapted state;

[0034] By connecting the respiratory secretion absorber to the respiratory secretion absorption tube 31, the respiratory secretions on the transparent mirror 12 can be directly absorbed. Because the respiratory secretions are relatively scattered on the transparent mirror 12, a larger suction force is required to achieve a larger range of respiratory secretions absorption through direct absorption. In order to avoid excessive suction force, which may cause patient tension and nausea, the respiratory secretions on the transparent mirror 12 are scraped off and flow into the respiratory secretion storage tank 25 before the respiratory secretions are absorbed. This can further ensure that the respiratory secretions on the transparent mirror 12 are completely absorbed, reducing the patient's tension and the possibility of nausea.

[0035] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
