Abstract
Description
[Technical Field]
[0001] This utility model relates to the technical field of medical consumables, and in particular to the technical field of laryngoscope consumables. [Background Technology]
[0002] Endotracheal intubation is a crucial step in the induction of general anesthesia and an important part of emergency care and monitoring of critically ill patients. Currently, the most common method of endotracheal intubation is oral endotracheal intubation using a video laryngoscope (during the procedure, the patient is kept supine with their head tilted back as far as possible. One hand holds the laryngoscope and inserts it into the oral cavity along the corner of the mouth, then slowly pushes the blade to the base of the tongue until the epiglottis is seen, while the other hand holds the endotracheal tube and inserts it along the groove of the tongue depressor on the laryngoscope blade).
[0003] Because a laryngoscope needs to be inserted into the larynx through the mouth, it inevitably comes into contact with the teeth, tongue, and soft tissues of the lips during the procedure. During this time, the laryngoscope may cause tooth damage or gum bleeding due to pressure. For some elderly patients, it may even cause teeth to loosen or fall out due to impact.
[0004] Currently, there are dental protectors available in clinical practice for temporary protection of teeth, such as the dental protector for assisting laryngoscope intubation (publication number CN106806972A), the dental cover for supporting laryngoscopes (publication number CN213696834U), and the auxiliary device for video laryngoscope lenses (publication number CN220344388U). However, these traditional protectors rely on prefabricated shapes and sizes, while different patients often have significant individual differences in oral structure (such as tooth arrangement and soft tissue morphology). This leads to the protectors not fitting tightly to the contact area. This mismatch not only reduces their protective effect on teeth but may also cause tooth damage or soft tissue compression injury due to local pressure concentration. [Utility Model Content]
[0005] The purpose of this invention is to solve the problems in the existing technology and to propose a laryngoscope protective film that is adaptable to individual anatomical differences and easy to operate, which can improve surgical safety and optimize the clinical operation experience.
[0006] To achieve the above objectives, this utility model proposes a disposable laryngoscope wrapping adhesive sheet, comprising, from bottom to top, a release paper layer, a first adhesive layer, an elastic buffer layer, a smooth sheet layer, a second adhesive layer, and a non-smooth sheet layer. The release paper layer can be peeled off from the first adhesive layer, and the second adhesive layer and the non-smooth sheet layer can be peeled off from the smooth sheet layer simultaneously.
[0007] Preferably, the release paper layer is a plastic film or high-density kraft paper treated with silicone oil, and the thickness of the release paper layer is controlled between 0.05 and 0.1 mm.
[0008] Preferably, the first adhesive layer is an acrylic pressure-sensitive adhesive layer, the second adhesive layer is a silicone gel layer, and the thickness of both the first adhesive layer and the second adhesive layer is controlled within 0.03 to 0.05 mm.
[0009] Preferably, the elastic buffer layer is an elastic rubber sheet or an elastic silicone sheet, and the thickness of the elastic buffer layer is controlled between 1 and 3 mm. The smooth sheet layer is a plastic film, and the thickness of the smooth sheet layer is controlled between 0.05 and 0.1 mm.
[0010] Preferably, the elastic buffer layer and the smooth sheet are bonded together by hot pressing.
[0011] Preferably, the non-smooth sheet is a non-woven fabric or a single-sided embossed plastic film, the thickness of the non-smooth sheet is controlled between 0.05 and 0.1 mm, and the side of the embossed plastic film with the pattern is the exposed side.
[0012] Preferably, when the non-smooth sheet is a single-sided embossed plastic film, a base layer is formed between the non-smooth sheet and the second adhesive layer by pre-applying adhesive liquid to reinforce them.
[0013] Preferably, the base layer is a polyurethane adhesive layer, an acrylic pressure-sensitive adhesive layer, or a hot melt adhesive layer.
[0014] Preferably, the smooth sheet layer is further provided with a mirror coating on the side facing the second adhesive layer.
[0015] Preferably, the mirror coating is a metal particle coating.
[0016] The beneficial effects of this utility model are:
[0017] 1) By combining the release paper layer, the first adhesive layer and the elastic buffer layer, this application allows the first adhesive layer to be used to adhere the elastic buffer layer to the laryngoscope surface when the release paper layer is removed. This allows the elastic buffer layer to disperse the local pressure of the laryngoscope on the teeth and soft tissues, reducing the risk of squeezing damage. It is especially suitable for elderly patients or those with fragile teeth. It also avoids the problem of poor protective effect caused by the shape of traditional protective mouthguards.
[0018] 2) By adding a smooth sheet, a second adhesive layer, and a non-smooth sheet on top of the elastic buffer layer, the coarse mode (retaining the non-smooth sheet) or the smooth mode (removing the non-smooth sheet) can be flexibly selected according to the oral structure and surgical needs of different patients. This effectively adapts to the different contact needs of the laryngoscope with the soft tissues of the teeth, tongue, and lips. (In the coarse mode, the embossed texture or fabric texture provides high friction to ensure the stability of the laryngoscope at the contact surface of the teeth and other parts, and prevents the laryngoscope from slipping. In the smooth mode, the smooth sheet is exposed, and the low friction characteristics reduce the mechanical stimulation of the soft tissues by the laryngoscope and reduce the risk of mucosal damage.)
[0019] 3) By adding a mirror coating to the smooth sheet surface, the clarity of the surgical field can be enhanced through reflection (forming an auxiliary function extension), making it easier for medical staff to observe the internal structure of the oral cavity and optimize the accuracy of cannulation.
[0020] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. [Attached Image Description]

Detailed Implementation Methods
[0027] Example 1:
[0028] See Figures 1 to 2 This embodiment includes a release paper layer 1, a first adhesive layer 2, an elastic buffer layer 3, a smooth sheet layer 4, a second adhesive layer 5, and a non-smooth sheet layer 6 arranged sequentially from bottom to top. The release paper layer 1 can be peeled off from the first adhesive layer 2, and the second adhesive layer 5 and the non-smooth sheet layer 6 can be peeled off from the smooth sheet layer 4 at the same time.
[0029] The release paper layer 1 is a plastic film or a high-density kraft paper treated with silicone oil, and the thickness of the release paper layer 1 is controlled between 0.05 and 0.1 mm; wherein the plastic film is a PP film, a PET film, or a PE film.
[0030] The first adhesive layer 2 is an acrylic pressure-sensitive adhesive layer, and the second adhesive layer 5 is a silicone gel layer. The thickness of both the first adhesive layer 2 and the second adhesive layer 5 is controlled between 0.03 and 0.05 mm. The acrylic pressure-sensitive adhesive layer has high initial tack and leaves no residue after peeling, making it very suitable for bonding to the surface of a laryngoscope. The silicone gel layer has moderate tack, which facilitates selective peeling and exposes the smooth sheet 4.
[0031] The elastic buffer layer 3 is an elastic rubber sheet or an elastic silicone sheet, and the thickness of the elastic buffer layer 3 is controlled between 1 and 3 mm. The smooth sheet layer 4 is a plastic film, and the thickness of the smooth sheet layer 4 is controlled between 0.05 and 0.1 mm. The plastic film is a PP film, PET film, or PE film, with a smooth and waterproof surface, which can also reduce the friction between the laryngoscope and the oral cavity when exposed. The elastic rubber sheet or elastic silicone sheet has good elasticity and can disperse pressure through buffering, reducing the squeezing damage of the laryngoscope to the teeth or oral soft tissues.
[0032] The elastic buffer layer 3 and the smooth sheet layer 4 are bonded together by hot pressing. Taking the smooth sheet layer 4 as a PE film and the elastic buffer layer 3 as an elastic silicone sheet as an example, since the melting point of the PE film is low, the PE film can be slightly melted on the surface during hot pressing and form a physical interlock with the silicone surface, thereby ensuring seamless bonding and maintaining interlayer flexibility.
[0033] The non-smooth layer 6 is a non-woven fabric or a single-sided embossed plastic film. The thickness of the non-smooth layer 6 is controlled between 0.05 and 0.1 mm. The side of the embossed plastic film with the pattern 61 is the exposed side. The single-sided embossed plastic film is a single-sided embossed PP film, a single-sided embossed PET film, or a single-sided embossed PE film, which can increase the friction between the laryngoscope and the oral cavity when exposed (to prevent the laryngoscope from slipping).
[0034] When the non-smooth sheet 6 is a single-sided embossed plastic film, a base layer is formed between the non-smooth sheet 6 and the second adhesive layer 5 by pre-applying adhesive to form a base layer for reinforcement; wherein, the base layer can enhance the tightness of the connection between the non-smooth sheet 6 and the second adhesive layer 5, thereby preventing the non-smooth sheet 6 from being torn off separately (i.e., the second adhesive layer 5 remains on the surface of the smooth sheet 4).
[0035] The base layer is a polyurethane adhesive layer, an acrylic pressure-sensitive adhesive layer, or a hot melt adhesive layer.
[0036] In addition, each product is individually sealed in an ethylene oxide sterilized bag, ready to use upon opening, ensuring single-use safety (this single-use design effectively avoids cross-contamination).
[0037] Example 2:
[0038] See Figures 3 to 5 The smooth sheet 4 is further provided with a mirror coating 7 on the side facing the second adhesive layer 5; wherein, the mirror coating 7 can help medical staff see the intraoral environment through reflection when the smooth sheet 4 is exposed, which facilitates laryngoscope operation.
[0039] The mirror coating 7 is a metal particle coating.
[0040] Everything else is the same as in Example 1.
[0041] The working process of this embodiment:
[0042] For areas requiring a rough surface (such as the tooth contact surface), first peel off the release paper layer 1, then use the first adhesive layer 2 to attach the slide to the laryngoscope surface (e.g., Figure 4 (As shown); For areas requiring a smooth surface (such as soft tissue contact areas), first peel off the release paper layer 1, then peel off the second adhesive layer 5 and the rough sheet layer 6 simultaneously, and finally use the first adhesive layer 2 to attach the sheet to the laryngoscope surface (as shown). Figure 5 (As shown).
[0043] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
