Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a novel artificial nose. Background Art

[0002] The air inhaled by tracheotomy patients is not heated or humidified through the nasal cavity, but the cold air is directly inhaled into the lungs. Long-term inhalation of dry cold air can easily lead to dryness of the respiratory mucosa and cause complications such as mucosal damage, restricted ciliary movement, sputum crust blockage and lung infection.

[0003] After many clinical experiments, we found that if a tracheotomy patient wears a metal tracheal tube, he or she cannot wear an artificial nose ventilator humidifier (the artificial nose can keep warm, moisturize and filter the gas inhaled into the airway. The existing technology uses an elastic adapter component to stably connect the artificial nose and the metal tracheotomy tube. It only needs to be inhaled through 0.9% NaCl oxygen atomization for 1-3 times in 24 hours to humidify the airway, which greatly reduces the patient's complications and the workload of the caregiver. However, in actual use, since the metal tracheotomy tube is fixed with the elastic adapter component, medical staff need to wear gloves to prevent bacterial infection when removing the metal tracheotomy tube for cleaning and disinfection. If gloves are not worn, it will be inconvenient to disassemble, which lacks certain practicality. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0029] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] Artificial nose is a medical product made of medical polymer materials with the same shape, color and softness as a real human nose. It is used for plastic surgery of patients with nasal defects caused by trauma or other diseases. Another type is saddle nose plastic surgery implant. Artificial nose does not have the sense of smell, heats the air and serves as the first line of defense for the lungs.

[0031] In the related art, the extension device of the artificial nose does not have a good disassembly function. Generally, the extension tube can only be disassembled by directly pulling it out by hand. During use, the extension tube must be touched by hand to be disassembled, which has certain limitations.

[0032] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a new artificial nose. When the extension tube 13 needs to be disassembled and assembled, it is only necessary to manually pull the pull rod 24. By retracting the stop block 22, the limitation on the mounting plate 26 is cancelled to realize the disassembly of the extension tube 13. There is no need to touch it with hands to pull it out, which is more convenient and improves the convenience of disassembly and assembly of the extension tube 13.

[0033] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0034] Combination Figure 1-Figure 4 The embodiment of the present application provides a new type of artificial nose, including a main body component 1; the main body component 1 includes: a connecting piece 12 is threadedly connected to one side of the artificial nose 11, an extension tube 13 is arranged on the connecting piece 12, and a disassembly component 2 is arranged on the connecting piece 12, and the disassembly component 2 includes: a mounting block 21 is fixedly connected to the outside of the connecting piece 12, a stopper 22 is slidably connected to the mounting block 21, a spring 23 is arranged inside the mounting block 21, and the two ends are respectively fixedly connected to the inside of the mounting block 21 and the outside of the stopper 22, a pull rod 24 is fixedly connected to the top of the stopper 22, a fixing plate 25 is fixedly connected to the outside of the mounting block 21, and a mounting plate 26 is fixedly connected to one end of the extension tube 13.

[0035] When ready for use, the connecting piece 12 is connected to the artificial nose 11 through a thread, and the air outlet of the artificial nose 11 is connected to the patient's breathing circuit. Then the operator pulls the pull rods 24 on both sides, and the pull rods 24 drive the block 22 to move into the mounting block 21. While the block 22 moves, it squeezes the spring 23. Then the operator drives the extension tube 13 to place the mounting plate 26 between the two fixed plates 25 and fit it with the connecting piece 12. Then the operator releases the pull rod 24. Under the action of the elastic force of the spring 23, the block 22 pops out to limit the mounting plate 26, and the installation is completed. When disassembly is required, the operator turns the device upside down, and then pulls the pull rod 24 to drive the block 22 to cancel the limit on the mounting plate 26, thereby canceling the limit on the extension tube 13, so that the extension tube 13 falls out due to gravity, and the disassembly is completed without the operator's hand touching the extension tube 13.

[0036] Specifically, two mounting blocks 21 are provided, two fixing plates 25 are symmetrically provided, both the connecting member 12 and the mounting plate 26 are provided with ventilation holes, and the mounting block 21 and the connecting member 12 are fixed by welding.

[0037] In some embodiments, a baffle 8 is fixedly connected to one side of the mounting block 21, and a through slot is provided on the baffle 8. The mounting plate 26 drives the extension tube 13 to pass through the through slot on the baffle 8 and connect with the disassembly assembly 2. The baffle 8 can shield the device close to the connecting member 12 to prevent too many devices from being close to the connecting member 12 during use, thereby causing friction between the user and the device and causing injury, thereby improving the safety of the device.

[0038] Specifically, the length of the through slot is greater than the length of the mounting plate 26 .

[0039] In some embodiments, the mounting block 21 is internally fixedly connected to a limit block 7. When the block 22 moves, the limit block 7 can limit the moving range of the block 22, thereby preventing the block 22 from being completely installed inside the mounting block 21. As a result, under the elastic force of the spring 23, the block 22 is stuck inside the device, and the operator is required to manually return it to its original position and remove it, thereby improving the stability of the device.

[0040] Specifically, the width of the stopper 22 is equal to the width of the limiting block 7 and is in the shape of a rectangular parallelepiped.

[0041] In some embodiments, one side of the stop block 22 is fixedly connected to an extrusion block 4. When the stop block 22 moves to limit the mounting plate 26, it drives the extrusion block 4 to squeeze the mounting plate 26, thereby fixing the stop block 22. At the same time, when the stop block 22 moves and contracts, it also drives the extrusion block 4 to enter the mounting block 21, thereby improving the fixing effect of the device.

[0042] Specifically, the side of the extrusion block 4 close to the mounting plate 26 is arc-shaped.

[0043] In some embodiments, the side of the block 22 away from the mounting block 21 is an inclined surface, so that when the mounting plate 26 is installed, the block 22 can be directly pressurized to move into the mounting block 21. When the mounting plate 26 is in contact with the connecting piece 12, the spring 23 automatically pops out the block 22 to limit and fix it, so that there is no need to pull the pull rod 24 first when installing the device, thereby improving the use efficiency of the device.

[0044] In some embodiments, a linkage assembly 3 is provided on the mounting block 21, and the linkage assembly 3 includes: a mounting shell 34 fixedly connected to the top of the mounting block 21, a push rod 31 fixedly connected to one side of the pull rod 24, a rotating rod 32 hinged to one end of the push rod 31, a pressing block 33 hinged to one end of the rotating rod 32, and slidably connected to the mounting shell 34.

[0045] During use, the operator presses the pressing block 33 on the mounting shell 34, and the pressing block 33 moves to drive the rotating rod 32 to rotate. The rotating rod 32 rotates to drive the push rod 31 to push the pull rod 24, thereby driving the stopper 22 to move, preventing the inconvenience of pulling the two pull rods 24 at the same time, so that the user does not need to pull the two pull rods 24 separately, providing convenience for the device.

[0046] Specifically, the push rod 31 and the pull rod 24 are fixed by welding.

[0047] In some embodiments, a telescopic rod 6 is provided inside the mounting shell 34, and both ends of the telescopic rod 6 are fixedly connected to the bottom of the pressing block 33 and the inside of the mounting shell 34 respectively. When the pressing block 33 moves, the telescopic rod 6 is driven to extend and retract at the same time. The telescopic rod 6 can limit the moving direction of the pressing block 33 to prevent the pressing block 33 from tilting when moving, thereby getting stuck inside the mounting shell 34, causing the device to be unable to be used normally.

[0048] Specifically, the telescopic rod 6 is a plurality of rod bodies sleeved together.

[0049] In some embodiments, a protective shell 5 is hinged on the top of the mounting shell 34, and the protective shell 5 can completely cover the pressing block 33, thereby preventing the user from accidentally touching the pressing block 33 when using the device and affecting the fixing effect of the device, thereby improving the stability of the device.
