Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a device for opening the airway. Background Technology
[0002] Traditional airway opening devices have a sealing strip and an inner container. The sealing strip is placed against the patient's chin and neck. A vacuum pump creates negative pressure on the surface of the patient's neck, causing soft tissue to move forward and widen the airway. However, in actual operation, due to differences in human facial shape, the sealing strip does not achieve the expected seal at the chin, resulting in the device's performance being less than expected. Utility Model Content
[0003] The purpose of this invention is to provide an instrument for opening the airway, solving the problem that traditional instruments for opening the airway cannot fit tightly to the jaw of patients with different facial shapes.
[0004] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:
[0005] An instrument for opening an airway is provided, mainly comprising: a container body, a sealing strip, a vacuum pump, a suction tube, a strip, and a corrugated cover; the sealing strip includes a groove and sliders, the groove being a flexible groove opening outwards, and four sliders inside the groove, each slider including a spherical end movable inside the groove, a prism end oriented towards the groove opening connected to the spherical end's axis, and a cylindrical end coaxial with the prism end; the cylindrical ends of the two sliders closest to the inner side of the groove are rotatably connected to the two ends of a strip, so that the strip, sliders, and groove form an adjustable-diameter ring; the other two sliders... The cylindrical ends of the block are rotatably connected to both ends of a corrugated hood, so that the corrugated hood, slider, and groove form another ring with an adjustable inner diameter. The sealing strip is fixed to the patient's chin through the two rings. The container body is fixedly connected to the sealing strip, which is set to abut against the patient's chin and neck. The container body and the sealing strip define a sealed cavity at the external position of the airway soft tissue in front of the neck. The inlet of the vacuum pump is connected to the sealed cavity through a suction pipe. The vacuum pump is used to create negative pressure inside the sealed cavity, thereby moving the neck surface and subcutaneous soft tissue toward the inside of the sealed cavity, thus opening the airway.
[0006] Furthermore, the spherical end of the slider is located inside the groove, the prism end is located between the groove openings, and the cylindrical end is located outside the groove.
[0007] Furthermore, plugs are fixedly connected to both ends of the slide. The end of the plug connected to the slide has a protrusion that fits into the internal groove of the slide. The protrusion is inserted into the internal groove of the slide and is interference-fitted with the slide.
[0008] Furthermore, the longitudinal section of the inner channel of the chute is a circle with an opening on one side, and the diameter of the circle is the same as the diameter of the spherical end.
[0009] Furthermore, the surface of the lower groove opening has barbs made of an elastic material.
[0010] Furthermore, the height of the inner wall of the groove matches the size of the prism end of the slider and is smaller than the diameter of the spherical end.
[0011] Furthermore, the chute is made of metal.
[0012] The advantages of this utility model compared to the prior art are:
[0013] An instrument for opening the airway is provided, which replaces the sealing strip that fits the jaw with a soft metal groove. By manually adjusting the curvature of the groove, the gap between the sealing strip and the jaw can be further reduced. There are four sliding sliders inside the groove, which are connected to the strip and the corrugated cover respectively. The user can flexibly adjust the connection position of the sealing strip, the strip and the corrugated cover according to their own facial contours, reducing the gap between the sealing strip and the jaw, thereby ensuring a tight fit between the sealing strip and the jaw.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1-7 As shown, this utility model provides an instrument for opening the airway, which mainly includes: a container body 4, a sealing strip 1, a vacuum pump 6, an air extraction tube 5, a strip 2, and a corrugated cover 3;
[0027] Combination Figure 8 The sealing strip 1 includes a groove 11 and sliders 13. The groove 11 is a flexible groove that opens outward. There are four sliders 13 inside the groove 11. Each slider 13 includes a spherical end 131 that can move inside the groove 11. The axial center of the spherical end 131 is connected to a prism end 132 facing the groove opening, and a cylindrical end 133 coaxial with the prism end 132. The cylindrical ends 133 of the two sliders 13 closest to the inner side of the groove 11 are rotatably connected to both ends of a strip 2, so that the strip 2, sliders 13, and groove 11 form a ring with an adjustable inner diameter. The cylindrical ends 133 of the other two sliders 13 are rotatably connected to both ends of a corrugated cover 3, so that the corrugated cover 3, sliders 13, and groove 11 form another ring with an adjustable inner diameter. The sealing strip 1 is worn on the patient's head and neck through the two rings.
[0028] The corrugated cover 3 is attached to the surface of the container body 4. The corrugated cover 3 allows the patient to maintain natural head movement while still allowing the container body 4 to effectively seal against the patient's neck skin.
[0029] The container body 4 is fixedly connected to the sealing strip 1, which is positioned to abut against the patient's chin and neck. The container body 4 and the sealing strip 1 define a sealed cavity at the external location of the airway soft tissue in front of the neck. The inlet of the vacuum pump 6 is connected to the sealed cavity through the suction pipe 5. The vacuum pump 6 is used to create negative pressure inside the sealed cavity, thereby causing the neck surface and subcutaneous soft tissue to move toward the inside of the sealed cavity, thus opening the airway.
[0030] The spherical end 131 of the slider 13 is located inside the groove of the slide 11, the prism end 132 is located between the openings of the slide 11, and the cylindrical end 133 is located outside the slide 11.
[0031] The two ends of the slide 11 are fixedly connected to the plugs 12. The end of the plug 12 connected to the slide 11 has a protrusion that fits into the inner groove of the slide 11. The protrusion is inserted into the inner groove of the slide 11 and is interference-fitted with the slide 11.
[0032] The longitudinal section of the inner groove of the slide 11 is a circle with an opening on one side, and the diameter of the circle is the same as the diameter of the spherical end 131, so that the spherical end 131 can slide freely inside the slide 11; the height of the inner wall of the slide 11 matches the size of the prism end 132 of the slider 13, restricting the prism end 132 from rotating between the openings of the slide 11; the height of the inner wall of the slide 11 is less than the diameter of the spherical end 131, to prevent the slider 13 from falling out of the slide 11.
[0033] The surface of the lower groove of the slide 11 has barbs made of elastic material, which allows the slider 13 to slide only under the action of external force.
[0034] The slide 11 is made of flexible metal, and the user can bend the slide 11 to the curvature of their own jaw, so that the slide 11 fits closely to the user's jaw.
[0035] The flexible metal groove 11 can be manually adjusted to fit the patient's jaw according to different face shapes. The spherical end 131 of the slider 13 can still slide inside the groove 11 when the curvature of the groove 11 changes. The size of the prism end 132 of the slider 13 matches the groove opening spacing of the groove 11 to prevent the slider 13 from rolling inside the groove 11. The elastic barbs on the surface of the lower groove opening can increase the friction between the slider 13 and the groove 11. The cylindrical end 133 of the slider 13 is rotatably connected to the strip 2 and the corrugated cover 3 respectively. The user can flexibly adjust the connection position of the sealing strip 1 with the strip 2 and the corrugated cover 3, reducing the gap between the sealing strip 1 and the jaw, thereby ensuring a tight fit between the sealing strip 1 and the jaw.
[0036] In this embodiment, the strip 2 is fixed to the patient's head and neck. The container body 4 and the sealing strip 1 form a sealed cavity on the skin surface of the patient's neck. The inside of the sealed cavity is connected to the inlet of the vacuum pump 6 through the air extraction pipe 5. The patient can manually change the curvature of the groove 11 on the sealing strip 1 to keep it in close contact with the chin. The slider 13 is slid inside the groove 11 by the cylindrical end 133 of the slider 13, so that the connection between the groove 11 and the strip 2 and the corrugated cover 3 is moved to the appropriate position, reducing the gap between the sealing strip 1 and the chin, thereby ensuring a close contact between the sealing strip 1 and the chin. The vacuum pump 6 is started to draw air into the sealed cavity to form a negative pressure, causing the patient's neck skin and subcutaneous soft tissue to move into the sealed cavity, thus opening the patient's airway.
[0037] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered as falling within the scope of protection of this utility model.
