Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a visual intubation mirror with a protective cover. Background Art

[0002] At present, the visual intubation soft mirror has been widely used by hospital departments such as anesthesiology, emergency department, ICU, and otolaryngology. Compared with ordinary intubation soft mirrors, the visual intubation soft mirror is less irritating to patients. It can display the oral and throat structures of the intubation process more clearly on the screen, making the intubation time of medical staff relatively shorter and the success rate higher. Because the visual intubation soft mirror is expensive, many grassroots hospitals are insufficiently equipped, but its frequency of use is high, and the visual intubation soft mirror needs to be sent to the supply room for disinfection and packaging after use, which will further extend the interval between the two uses of the visual intubation soft mirror, resulting in its inability to meet high-frequency usage scenarios. In addition, the visual intubation soft mirror is expensive, and the repair cost is high after damage. Repeated disinfection may reduce its service life, which invisibly increases the cost of purchasing consumables for the department. The loss of the mirror body during repeated disinfection will reduce the quality of the visual intubation soft mirror during use and the operating experience of the physician. The visual intubation soft mirror is the gold standard for dealing with foreseeable difficult airways. It can also perform double-lumen tube positioning and is also the gold standard for endotracheal examinations and endotracheal tube examinations. The visual laryngoscope is also a powerful airway management tool for dealing with common and difficult airways. Therefore, medical staff will choose a visual intubation soft mirror or a visual laryngoscope based on the airway management of different patients. In hospitals where the pace of medical work is tight, different intubation mirrors are frequently used. In the prior art, there is a lack of a visual intubation mirror that can be simply set up to function as both a visual intubation soft mirror and a visual laryngoscope, and can also avoid repeated disinfection and cross-infection problems.

[0003] In the prior art, a patent document with announcement number CN205964009U proposes a multifunctional intubation laryngoscope, including a display, a standard laryngoscope blade, a slotted laryngoscope blade, a light stick and a fiberscope. The display has a handheld body, and the handheld body is provided with an upper video connector and a power source connected to the display and the upper video connector. The proximal ends of the standard laryngoscope blade, the slotted laryngoscope blade, the light stick and the fiberscope are all provided with a lower video connector that can be connected to the upper video connector. Although the multifunctional intubation laryngoscope can connect multiple tools through a display to achieve different functions, each tool still needs to be disinfected after use and when it is taken out of the patient's mouth to avoid cross infection. Therefore, the multifunctional intubation laryngoscope cannot avoid equipment loss caused by frequent disinfection.

[0004] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the inventor studied a large number of documents and patents when making the present utility model, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present utility model does not have the characteristics of these prior arts. On the contrary, the present utility model already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Utility Model Content

[0005] In response to the shortcomings of the prior art, the utility model proposes a visual intubation mirror with a protective cover, and in particular, a visual intubation mirror that can be used in conjunction with different protective covers to achieve the two tool functions of a visual intubation soft mirror and a visual laryngoscope. It is a visual intubation mirror that can cope with different scenarios, and aims to solve one or more technical problems in the prior art.

[0006] In the prior art, the visual intubation soft mirror has a soft mirror body that can enter the respiratory tract for examination; while the visual intubation laryngoscope has a relatively harder mirror body, which is placed in the patient's mouth and used to lift the patient's epiglottis upwards to expose the glottis to guide tracheal intubation. Therefore, the two types of intubation mirrors are suitable for different intubation needs. In clinical practice, different intubation mirrors are frequently replaced for different patients, which is inconvenient for medical staff. In addition, the visual intubation mirror is expensive and has high repair costs after damage, and repeated disinfection will reduce its service life, which invisibly increases the cost of purchasing consumables for the department; at the same time, the loss of the visual intubation soft mirror during repeated disinfection will reduce the quality and operating experience of the visual intubation soft mirror during use.

[0007] In order to cope with various difficult intubation situations, the prior art has already presented a technical solution that combines an endotracheal intubation mirror with a laryngoscope. For example, the patent document with publication number CN220158971U discloses a multifunctional visual endotracheal intubation device, which includes a multifunctional portable handle, a portable display screen, and a hot-swappable lens module kit, wherein the lens module kit includes a visual intubation core kit, a visual laryngoscope blade kit, and an electronic bronchoscope kit; the multifunctional portable handle is provided with a stepless adjustment button, a camera system button, and a switch; the upper end of the multifunctional portable handle can be connected to the interface of the portable display screen. This technical solution adopts a hot-swappable lens module kit to provide visualization of intubation in a variety of ways. Clinicians can select the most suitable lens module kit according to the specific conditions of the patient's airway to ensure the safety of endotracheal intubation and improve the success rate of intubation. However, although the technical solution can realize the switching of different lens kits, a separate lens assembly is required in each working mode, and the switching of different functions can only be realized after the different lens assemblies and imaging units are disassembled and assembled, and the same lens assembly cannot be used to realize different operating functions.

[0008] Therefore, in response to the above technical problems, the present utility model proposes a visual intubation mirror with a protective cover, including a soft mirror portion for collecting images of the patient's laryngeal structure, the soft mirror portion can have the function of a laryngoscope by being detachably equipped with a laryngoscope protective cover, wherein the soft mirror portion is configured with a bendable soft mirror body, the laryngoscope protective cover is built with a plurality of guide grooves for limiting the extension direction of the soft mirror body, and some of the guide grooves are arranged in a circumferential manner in the internal cavity of the laryngoscope protective cover so that the soft mirror body can be placed in a partially coiled form inside the laryngoscope protective cover. Compared with the above-mentioned prior art, the soft mirror portion in the present utility model can have the function of a laryngoscope by being placed in a partially coiled form inside the laryngoscope protective cover. Based on the above-mentioned distinguishing technical features, the technical problems to be solved by the present utility model may include: how to achieve switching of different functions of the visual intubation mirror. Specifically, by providing a laryngoscope protective cover at the soft mirror portion of the visual intubation scope, the visual intubation scope that originally only has the function of a soft mirror can be made to function as a laryngoscope, so that one mirror can be used for multiple purposes, reducing the tedious work of medical staff frequently replacing the visual intubation scope. In addition, since one of the purposes of providing the protective cover is to prevent cross infection, this means that medical staff must remove and replace the used protective cover on the visual intubation scope before performing an airway examination on the next patient. Therefore, medical staff can select a suitable new protective cover to determine the purpose of the visual intubation scope while replacing the protective cover according to the actual examination needs of the next patient, reducing the extra work caused by changing the type of visual intubation scope.

[0009] According to a preferred embodiment, the laryngoscope protective cover includes a vertical section and a flat section connected to each other, and the guide groove includes a first guide groove and a second guide groove, wherein the first guide groove is arranged in the vertical section, and the second guide groove is arranged in the flat section. Compared with the above-mentioned prior art, the laryngoscope protective cover in the utility model is composed of different connecting sections to form the main structure of the laryngoscope. Based on the above-mentioned distinguishing technical features, the technical problems to be solved by the utility model may include: how to provide a storage space for the soft mirror body on the laryngoscope protective cover to ensure the function of the visual laryngoscope. Specifically, since the soft mirror body has a longer length than the laryngoscope protective cover, if the soft mirror body is directly assembled with the laryngoscope protective cover, the excess soft mirror body will be exposed outside the laryngoscope protective cover, and an integrated visual laryngoscope assembly cannot be formed. To this end, the utility model is provided with a guide groove structure for accommodating the soft mirror body inside the laryngoscope protective cover, so that the soft mirror body with excess length can be assembled with the laryngoscope protective cover by being placed in the guide groove structure. The vertical section and the flat section enable the laryngoscope protective cover to have an appearance similar to that of an ordinary laryngoscope, making it easier for medical personnel to lift the epiglottis in the patient's mouth for intubation. In addition, guide grooves are provided in both the vertical section and the flat section, so that the configuration and presentation of the soft mirror body in the laryngoscope protective cover can be limited to meet assembly and use requirements.

[0010] According to a preferred embodiment, the first guide groove is attached to the inner wall of the vertical section, the first guide groove has a spiral passage in the vertical section, and the end of the first guide groove is connected to the start of the second guide groove. Compared with the above-mentioned prior art, the different guide groove structures of the utility model can be connected at the flat section close to the laryngoscope protective cover. Based on the above-mentioned distinguishing technical features, the technical problems to be solved by the utility model may include: how to achieve the transition accommodation of the soft mirror body between different sections of the laryngoscope protective cover. Specifically, by setting the switching areas of different guide grooves at the connection of different sections of the laryngoscope protective cover, the extension direction of the soft mirror body can be accurately switched. Furthermore, by configuring the first guide groove in a spiral shape, the soft mirror body can also be placed in the laryngoscope protective cover in a coiled form, thereby ensuring that the soft mirror body that is significantly longer than the laryngoscope protective cover can also be adapted to the laryngoscope protective cover.

[0011] According to a preferred embodiment, the second guide groove extends along the length direction of the flat section, so that the assembled soft mirror lens located at the end of the soft mirror body is located at a preset position of the flat section. The laryngoscope protective cover is similar in appearance to an ordinary laryngoscope blade, and its end is provided with an upwardly tilted structure, which can not only facilitate the lifting of the epiglottis in the patient's mouth and expose the glottis, but also is in a better position for medical personnel to observe the patient's oral condition using a visual intubation mirror. The guide groove is arranged inside the tilted structure so that the lens on the soft mirror can be correctly placed, ensuring that the soft mirror placed in the laryngoscope protective cover can still correctly capture image information in the patient's mouth.

[0012] According to a preferred embodiment, an anti-fog coating is provided at the end of the flat section corresponding to the soft mirror lens to reduce the effect of water mist. The laryngoscope protective cover will extend into the patient's throat, which is prone to fogging at the lens due to factors such as water vapor. The anti-fog coating can reduce such effects and avoid blurring of the images collected by the soft mirror.

[0013] According to a preferred embodiment, the visual intubation mirror also includes a display part and a handle part, the top end of the handle part is connected to the display part, and the bottom end of the handle part is connected to the soft mirror part. The soft mirror part is responsible for entering the patient's oral cavity and collecting images in the oral cavity; the handle part is the middle part of the visual intubation mirror, and it can be used as a part for medical staff to hold, regardless of whether the soft mirror part is equipped with a soft mirror protective cover or a laryngoscope protective cover. The handle part is made of hard material as a whole and can withstand the gripping force of medical staff; the display part can display the image information collected from the soft mirror part to guide medical staff to perform inspections or intubations.

[0014] According to a preferred embodiment, the handle portion includes a handle body for hand gripping, and the side wall of the handle body is provided with anti-slip patterns for enhancing gripping stability.

[0015] According to a preferred embodiment, the side wall of the handle is also provided with an external connector, which can be connected to external equipment, and the external connector is connected to the channel outlet provided at the lens of the soft endoscope through the soft endoscope body. The external connector serves as a working channel interface of the visual intubation mirror, and can be connected to external equipment for filling and draining liquids when a laryngoscope protective cover is not provided.

[0016] According to a preferred embodiment, the soft mirror part includes a soft mirror base connected to the beginning of the soft mirror body, and the outer surface of the soft mirror base is provided with anti-skid protrusions for improving the stability of the connection between the laryngoscope protective cover and the handle part. The soft mirror base can play two roles, one is to protect the root of the soft soft mirror body, and the other role is to assist in fixing the protective cover by providing the anti-skid protrusions.

[0017] According to a preferred embodiment, the sum of the lengths of the first guide groove and the second guide groove in the laryngoscope protective cover is the same as the length of the flexible mirror body. Such a configuration enables the flexible mirror body to be exactly placed in the laryngoscope protective cover, facilitating the installation and use of the visual intubation mirror.

[0018] The beneficial technical effects of the utility model are at least as follows:

[0019] (1) The visual intubation scope of the utility model can avoid the damage to the visual intubation scope caused by frequent disinfection by configuring different protective covers, and can also make the visual intubation scope play two different effects equivalent to the visual intubation soft scope and the visual intubation laryngoscope, without the need to repeatedly switch between the soft scope and the laryngoscope, thus simplifying the operation process. In addition, the use of the form of replacing the protective cover can reduce the workload of medical staff in frequently replacing the visual intubation scope, improve the efficiency of the operation and the patient's physical feeling; for grassroots hospitals or beginners, only one visual intubation scope needs to be purchased for two different application scenarios, which significantly reduces the cost of use.

[0020] (2) Since the visual intubation soft mirror is the gold standard for treating foreseeable difficult airways and can also be used for positioning double-lumen tubes, and is also the gold standard for endotracheal examinations and endotracheal tube examinations, the present invention adopts the soft mirror as the main body and makes improvements thereon, so that the soft mirror can realize the function of a laryngoscope while retaining its own functions, thus achieving dual purposes with one mirror.

[0021] (3) The video intubation scope of the present invention is equipped with a disposable protective cover, which is replaced after use. This not only protects the soft mirror portion of the video intubation scope and avoids cross infection, but also medical staff must remove and replace the used protective cover on the video intubation scope before performing an airway examination on the next patient. Therefore, medical staff can replace the protective cover and select a suitable new protective cover to determine the purpose of the video intubation scope based on the actual examination needs of the next patient, thereby reducing the extra work caused by changing the type of video intubation scope.

DETAILED DESCRIPTION

[0030] The utility model is described in detail below in conjunction with the accompanying drawings.

[0031] Definition of orientation: The end closest to the medical staff is the starting point, and the end closest to the patient is the end point.

[0032] The utility model relates to a visual intubation mirror with a protective cover, which is used for assisting intubation and airway inspection. Figure 1 As shown, the soft mirror part 300 is used to collect the patient's airway image. Preferably, the soft mirror part 300 includes a soft mirror body 310, a soft mirror base 320 and a soft mirror lens 330, wherein the soft mirror body 310 is made of a soft material and has a tubular appearance, and can be used as follows: Figure 2 As shown in the figure, the soft mirror lens 330 is located at the end of the soft mirror body 310, and the soft mirror base 320 is located at the beginning of the soft mirror body 310. The soft mirror protective cover 400 or the laryngoscope protective cover 500 protects the soft mirror part 300 by sleeve-fitting the mouth part on the soft mirror base 320, thereby isolating the soft mirror part 300 from direct contact with the tissue in the patient's body. Figure 6 As shown, the shape of the soft mirror protective cover 400 is consistent with that of the soft mirror part 300. It has a long strip-shaped protective cover body with a length close to that of the soft mirror body 310. Its lowermost end is closed, while its uppermost mouth is open in a trumpet-shaped form. Its shape is similar to that of the soft mirror base 320. The shape of the laryngoscope protective cover 500 is similar to that of a conventional laryngoscope, such as Figure 4 As shown, the laryngoscope protective cover 500 consists of two parts, a vertical section 510 with a flat appearance and a flat section 520 with an arc, wherein the end of the flat section 520 away from the vertical section 510 is provided with an upwardly tilted structure, which can facilitate medical personnel to lift the epiglottis in the patient's mouth and expose the glottis.

[0033] Preferably, if Figure 1 , Figure 6 As shown, the soft mirror portion 300 of the visual intubation mirror can be equipped with a soft mirror protective cover 400 or a laryngoscope protective cover 500, so that the visual intubation mirror has the functions of a soft mirror or a laryngoscope. Figure 5 As shown, a guide groove for limiting the travel direction of the soft mirror body 310 is provided inside the laryngoscope protective cover 500. The guide groove includes two sections, wherein the first guide groove 511 is provided in the vertical section 510, and the second guide groove 521 is provided in the flat section 520, and the end of the first guide groove 511 is connected to the start of the second guide groove 521. By pushing the soft mirror body 310 into the laryngoscope protective cover 500, the medical staff can adjust the length of the soft mirror body 310 inside the laryngoscope protective cover 500, and finally the soft mirror lens 330 can be configured at a preset position, that is, the position where the soft mirror lens 330 is located at the end of the second guide groove 521.

[0034] Preferably, if Figure 5As shown, the first guide groove 511 is attached to the inner wall of the vertical section 510 and has a coiled structure, which makes the soft mirror body 310 also have a spiral path in the first guide groove 511. Since the detection parts of the laryngoscope and the soft mirror are different, the laryngoscope is mainly used to examine diseases in the oral cavity, larynx, vocal cords and other parts, while the soft mirror is placed in the patient's lower respiratory tract through the mouth or nose to observe lung, trachea and bronchial lesions. Therefore, there is a certain difference in length between the laryngoscope and the soft mirror. Generally speaking, the length of the laryngoscope is usually 180mm. In contrast, the length of the soft mirror is longer, for example 300-700mm, especially 350-550mm, and especially 350mm-450mm. When the soft mirror body 310 is placed in the laryngoscope protective cover 500, its length will be significantly longer than the outer length of the laryngoscope protective cover 500 and cannot be used. In order to resolve such a contradiction, such as Figure 5 As shown, the first guide groove 511 in the vertical section 510 can be specifically arranged in a shape of multiple overlapping circles, such a shape enables the partial structure of the soft mirror body 310 to be assembled in the laryngoscope protective cover 500 in the same form under the guidance of the first guide groove 511, thereby ensuring that the soft mirror body 310 longer than the laryngoscope protective cover 500 can be adapted to the laryngoscope protective cover 500. Preferably, by adjusting the number of circles of the first guide groove 511 in the vertical section 510, it can be suitable for the assembly of soft mirror bodies 310 of different lengths.

[0035] In order to facilitate the placement of the soft mirror body 310 in the laryngoscope protective cover 500, the first guide groove 511 is arranged in a manner of being attached to the inner wall of the vertical section 510. Such a setting reduces the curvature of the first guide groove 511 as much as possible, thereby reducing the resistance of the soft mirror body 310 during the placement process, improving the efficiency of configuring the soft mirror body 310 in the laryngoscope protective cover 500, and is suitable for the assembly of a relatively short soft mirror body 310. Since different models of soft mirrors have soft mirror bodies 310 of different lengths, when medical staff need to place a relatively long soft mirror body 310 into the laryngoscope protective cover 500, the efficiency of the configuration method of gradually pushing the soft mirror body 310 from the opening of the vertical section 510 into the laryngoscope protective cover 500 is relatively low. For the purpose of improving efficiency, the vertical section 510 in the laryngoscope protective cover 500 of the utility model can be configured in an openable form, so that the soft mirror body 310 can be configured more quickly by opening the vertical section 510. Specifically, in this embodiment, the vertical section 510 can be divided into a cavity for accommodating the coiled soft lens body 310 and a detachable cover body, and the cover body can be tightly buckled on the body to achieve the closure of the vertical section 510. Medical staff can open the cover to expose the cavity inside the vertical section 510, so as to more conveniently place the coiled soft lens body 310 inside the first guide groove 520, avoiding the process of inserting the soft lens body 310 from the opening of the vertical section 510 being too lengthy or encountering obstacles.

[0036] Preferably, if Figure 5 As shown, the second guide groove 521 has a guide channel that conforms to the tilting arc of the laryngoscope protective cover 500, so the soft mirror lens 330 configured in the second guide groove 521 can also capture the patient's oral image at an angle that matches the tilting arc, so that the angle of the oral image captured by the image sensor 331 provided in the soft mirror lens 330 corresponds to the actual situation. Preferably, the sum of the lengths of the first guide groove 511 and the second guide groove 521 should be equivalent to the length of the soft mirror body 310 to ensure that the soft mirror body 310 can be just assembled in the laryngoscope protective cover 500.

[0037] Preferably, if Figure 4 As shown, the end of the flat section 520 in the laryngoscope protective cover 500 away from the vertical section 510, that is, the position corresponding to the soft mirror lens 330, is provided with an anti-fog coating 522. Figure 3 As shown, since the soft mirror part 300 collects the oral image through the image sensor 331 arranged on the soft mirror lens 330, the anti-fog coating 522 is covered on the position of the soft mirror lens 330 to ensure that the end of the laryngoscope protective cover 500 located at the patient's throat will not be fogged due to factors such as water vapor, so that the image sensor 331 can also collect clear images through the laryngoscope protective cover 500.

[0038] Preferably, if Figure 1 As shown, the visual intubation scope also includes a display unit 100 and a handle unit 200, wherein the top end of the handle unit 200 is connected to the display unit 100, and the bottom end of the handle unit 200 is connected to the soft mirror unit 300. Overall, the handle unit 200 is located in the middle of the visual intubation scope, which is suitable for medical staff to hold to maintain the stability of the entire visual intubation scope. An electrical signal path is provided in the handle unit 200, and the two ends of the path are respectively connected to the soft mirror unit 300 and the display unit 100, so that the image information obtained by the soft mirror unit 300 can be transmitted to the display unit 100. The three parts of the visual intubation mirror have different functions respectively: the soft mirror part 300 is responsible for entering the patient's oral cavity and collecting images in the oral cavity; the handle part 200 is the middle part of the visual intubation mirror. No matter whether the soft mirror part 300 is equipped with a soft mirror protective cover 400 or a laryngoscope protective cover 500, it can be used as a part for medical staff to hold. The whole is made of hard material and can withstand the gripping force of medical staff; and the display part 100 can display the image information collected from the soft mirror part 300 to guide medical staff to perform inspection or intubation.

[0039] Preferably, if Figure 1As shown, the display unit 100 includes a display 110, a rotating shaft 120, and a base 130. Specifically, the rotating shaft 120 is located between the display 110 and the base 130, so that the display 110 can perform a flipping movement with the rotating shaft 120 as the axis. Different medical staff may have different sight heights, and the flipping of the display 110 allows the display 110 to display the structures in the patient's oral cavity to different medical staff at a suitable angle.

[0040] Preferably, the display 110 can be integrated on the handle portion 200, or an independent display device can be connected externally as an alternative. Specifically, a signal interface for signal export can be set on the base 130 of the display portion 100, and the image obtained by the soft mirror portion 300 can instantly transmit the observation information collected by the soft mirror lens 330 through the signal interface, and the observation information can be more clearly displayed on an independent large-screen display device. Such a setting can be used in some situations where the patient's internal structure cannot be clearly displayed due to the limited resolution of the display screen of the visual intubation scope, so as to facilitate detailed inspection of the lesion site in the patient's body and difficult intubation of difficult airways.

[0041] Preferably, if Figure 1 As shown, the handle portion 200 includes a handle body 210, which is used for the medical staff to grasp. Whether the soft endoscope body 310 is equipped with a soft endoscope protective cover 400 or a laryngoscope protective cover 500, it can be used as a part for the medical staff to grasp. Preferably, in order to enhance the stability of grasping, a plurality of anti-slip lines 220 are provided on the side wall of the handle portion 200.

[0042] Preferably, if Figure 1 As shown, the side wall of the handle portion 200 is also provided with an external joint 230, which is outside the protection range of the soft mirror protective cover 400 and the laryngoscope protective cover 500. Figure 1 , Figure 3As shown, the external connector 230 is connected to the channel outlet 332 provided on the soft mirror lens 330 through the soft mirror body 310. The setting method of the external connector 230 can refer to the prior art, such as the patent document with the announcement number CN214965359U, which provides a soft mirror device with an independent channel, the channel of the soft mirror device is used for perfusing and aspirating liquid, and is provided with a working interface for connecting with medical equipment. The function of perfusing liquid includes using an irrigator to perfuse physiological saline or other necessary drugs into the airway through the working interface, for the purpose of diluting sputum, flushing the lesion site, etc.; and the function of aspirating liquid includes using an aspirator to aspirate secretions, sputum, etc. in the airway through the working interface of the soft mirror, so as to keep the airway unobstructed for better observation and operation. The setting of the external connector 230 provides the visual intubation mirror with an interface for connecting with external equipment. In the case where the soft mirror protective cover 400 or the laryngoscope protective cover 500 is not provided, it can be connected with external equipment. Liquid is infused and discharged through the channel provided inside the soft mirror body 310 and the channel outlet 332 provided at the position of the soft mirror lens 330, so as to balance the internal pressure of the patient's body and ensure the success rate of the operation.

[0043] Preferably, if Figure 1 As shown, the soft mirror part 300 also includes a soft mirror base 320. The soft mirror base 320 is connected to the handle body 210 and is located at the beginning of the soft mirror body 310, which can reduce the risk of the soft soft mirror body 310 breaking at the root. At the same time, the outer surface of the soft mirror base 320 is provided with a plurality of anti-skid protrusions 321, and the mouths of the two protective covers can be made of elastic materials, so the two protective covers can prevent themselves from slipping off the visual intubation mirror by sleeve-fitting the mouths on the anti-skid protrusions 321 on the outer surface of the soft mirror base 320. Preferably, the soft mirror base 320 and the anti-skid protrusions 321 thereon can be made of rubber.

[0044] Preferably, if Figure 6As shown, the length of the soft lens protective cover 400 is adapted to the length of the soft lens main body 310. The "adaptation" here does not mean that when the soft lens protective cover 400 is assembled, its end is completely fitted with the soft lens lens 330 of the soft lens main body 310, but there is a certain gap that does not affect the image acquisition effect of the soft lens lens 330. The existence of the gap reduces the difficulty of inserting the soft lens into the soft lens protective cover 400 or separating it from the soft lens protective cover 400. Preferably, the gap between the soft lens protective cover 400 and the soft lens main body 310 can be reserved for about 0.1 to 0.5 mm. The setting of the soft lens protective cover 400 of the utility model can refer to the prior art, such as the patent document with announcement number CN209489990U, which provides a soft lens protective cover and a visual soft lens thereof, and the soft lens protective cover includes: a tube body cover and a lens cover, the lens cover is arranged on one end of the tube body cover, and the tube body cover and the lens cover are detachably connected. The protective cover is put on the outer surface of the soft lens after disinfection and is removed and discarded after use, so that one person has one protective cover. This will not cause cross infection among patients, but also save the soft lens from frequent disinfection, reduce the corrosion of the disinfectant to the soft lens, and greatly increase the frequency of use of the soft lens. At the same time, the cost of the protective cover is acceptable.

[0045] Preferably, when medical personnel need to use the laryngoscope function of the visual intubation mirror, they need to select the laryngoscope protective cover 500 and sleeve it on the soft mirror part 300 of the visual intubation mirror. The medical personnel first hold the end of the soft mirror body 310 where the soft mirror lens 330 is located, and send it from the mouth of the laryngoscope protective cover 500 into the first guide groove 511 in the vertical section 510. Then, the medical personnel can choose to continue to send the end of the soft mirror body 310 to the position of the second guide groove 521 in the flat section 520 according to the length of the soft mirror body 310 or their own habits, or open the cover of the vertical section 510 to manually adjust the configuration mode of the coiled shape of the soft mirror body 310 in the vertical section 510, and make the soft mirror lens 330 at the end of the second guide groove 521. Preferably, at least the curved flat section 520 in the laryngoscope protective cover 500 is made of transparent material, which ensures that the soft mirror lens 330 can collect image information in the patient's oral cavity through the laryngoscope protective cover 500, and can also facilitate medical personnel to observe the posture of the soft mirror body 310 in the laryngoscope protective cover 500. Since the laryngoscope protective cover 500 has a guide groove, the soft mirror body 310 can move in a predetermined direction under the push of medical personnel until the soft mirror lens 330 can enter the second guide groove 521 and abut against the end of the second guide groove 521. After the above work is completed, the medical staff can sleeve the mouth of the laryngoscope protective cover 500 on the anti-slip protrusion 321 on the outer surface of the soft mirror base 320. In addition, in addition to the anti-slip protrusion 321 sleeved on the outer surface of the soft mirror base 320 to prevent slipping, the two protective covers can be further fixed by setting a 5mm wide Velcro connected to the mouth position, and the fixing position of the Velcro is located on the surface of the handle body 210 of the visual intubation mirror.
