Description

Technical Field

[0001] The present invention relates to the technical field of lighting devices, and in particular to a lighting device and a method thereof for otolaryngology nursing. Background Art

[0002] Otolaryngology involves the diagnosis and treatment of diseases of the ear, nose, pharynx, larynx and related head and neck areas. In otolaryngology nursing work, nurses need to provide comprehensive and meticulous care for patients. For example, in ear care, it may be necessary to clean the external auditory canal secretions and observe the condition of the eardrum; in nasal care, the nasal cavity needs to be rinsed and the condition of the nasal mucosa needs to be checked; throat care may involve nebulizer inhalation therapy and observation of laryngeal lesions. Accurate nursing operations play a vital role in the treatment effect of the disease, the patient's recovery process and the prevention of complications. Therefore, a lighting device that can provide a clear lighting environment is very important.

[0003] At present, the commonly used lighting devices in ENT nursing work are head-mounted forehead mirrors and ordinary wall-mounted examination lamps. The light intensity of head-mounted forehead mirrors is low, while ordinary wall-mounted examination lamps can provide relatively bright overall lighting and can be freely adjusted within a certain range, but its adjustment range is limited, and it is difficult to accurately focus on narrow and deep cavities such as the ear, nose and throat when necessary. When detailed observation of specific parts is required, ordinary examination lamps cannot meet the needs of local lighting, which may increase the difficulty of operation for nursing staff due to poor light, and may even cause unnecessary damage to patients due to unclear vision. In addition, ordinary wall-mounted examination lamps need to be manually adjusted by medical staff during use, and medical staff are prone to contamination of lamps during the nursing process, and need to frequently disinfect the lamps. If the disinfection is not thorough, it may also cause cross-infection and other problems, bringing potential risks to patients. Summary of the invention

[0004] The object of the present invention is to provide a lighting device and method for otolaryngology care, so as to enrich the usage scenarios and avoid cross infection, so as to solve the problems raised in the above background technology.

The floating rod can penetrate the ferromagnetic top plate and press on the magnetic suction seat.

[0008] Preferably, the mounting seat is a cylindrical structure, and the suspension rod is connected to the top of the main lamp, a limiting groove is provided on the mounting seat, and a magnetic seat is installed on the top of the limiting groove; The top end of the suspension rod is fixedly connected with a ferromagnetic top plate, and a ratchet plate is fixedly installed on the ferromagnetic top plate.

[0009] Preferably, a wire reel is provided in the mounting seat, and the main light is directly connected to the wires in the wire reel through a cable, and the ring light is connected to the wire reel by means of an electrical terminal.

[0010] Preferably, the disinfectant spraying structure includes a mounting seat arranged on the hanging bracket, and a clamp is arranged on the mounting seat. The disinfectant bottle can be installed upside down through the mounting seat and the clamp, and a rubber plug is arranged in the disinfectant bottle to prevent the disinfectant from flowing out.

[0011] Preferably, the disinfectant spraying structure also includes a hanging seat arranged on the wall-mounted seat, and a pressing tube is installed in the hanging seat, and a spray head is connected to the pressing tube.

[0012] Preferably, the pressing structure includes an axle seat installed on the hanging seat, and a ratchet gear is rotatably installed in the axle seat, a push rod is coaxially installed on the ratchet gear, and when the hanging rod is inserted into the hanging seat, the ratchet gear is on the moving path of the ratchet plate.

[0013] Preferably, at least three push rods are arranged in a ring on the axle of the ratchet gear, and an inclined seat is fixedly connected to the pressing tube, and the inclined seat is located on the rotation path of the push rod.

[0014] A lighting method for a light-supplying lighting device for ENT nursing, the lighting method comprising the following steps: S1, first, for wall-mounted range lighting, the main light and the ring light are connected to the mounting base through the suspension rod, and the disposable protective cover is installed on the control rod through the clamp, and then the control rod is used to apply tension to deform the adjustment bracket, so as to drive the main light and the ring light to move and adjust within a certain range. At this time, the main light and the ring light are turned on at the same time to perform range lighting; S2, hold the main light for fixed-point centralized lighting. First, press the take-up seat to compress the gas in the ventilation box, so that the floating rod rises from the gas cylinder and presses on the magnetic seat to generate a reaction force, separate the suspension rod from the mounting seat, and then completely take the main light off the mounting seat. At this time, only the main light is turned on to provide targeted and precise local lighting for the patient. S3. Finally, the used main lamp is reinstalled on the adjustment bracket, and the suspension rod on the main lamp is inserted into the mounting seat so that they are connected together under the action of magnetic force. At the same time, the pressing structure on the wall mounting seat is driven by the ratchet plate on the suspension rod, so that the disinfectant spraying structure sprays disinfectant toward the position of the taking seat, and the handheld part is disinfected in time for the next use.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Diverse lighting modes to meet the needs of different scenarios. The present invention provides two modes: wall-mounted range lighting and handheld main light fixed-point centralized lighting. When wall-mounted lighting is used, the main light and the ring light are turned on at the same time. The positions of the main light and the ring light can be adjusted by the control rod to achieve range lighting within a certain range. It is suitable for general inspection and nursing scenarios. When precise local lighting of the patient is required, the main light can be easily removed from the mounting bracket and used alone, free from the restriction of the adjustment bracket, to meet the needs of detailed observation of specific parts of narrow and deep cavities such as the ear, nose and throat, greatly enriching the use scenarios and improving the pertinence and practicality of lighting.

[0016] 2. Effectively avoid cross infection. On the one hand, a disposable protective cover can be installed on the control rod through a clip to avoid contamination of the control rod during nursing. On the other hand, when the main lamp is reinstalled on the mounting seat, the ratchet plate on the suspension rod can drive the pressing structure to make the disinfectant spraying structure spray disinfectant to the receiving seat, so as to disinfect the handheld part in time, reduce the risk of cross infection caused by lamp contamination and incomplete disinfection, and ensure the safety of patients.

[0017] 3. The adjustment bracket adopts multiple rods connected by movable joints, and a damping self-locking structure is set, which is convenient for nursing staff to easily adjust the lighting position through the control lever. A pick-up seat is set on the back of the main light. The gas in the ventilation box is compressed by pressing the pick-up seat, so that the float rod rises and presses the magnetic seat to generate a reaction force, thereby separating the suspension rod from the mounting seat and easily removing the main light. The operation process is simple and labor-saving. At the same time, the self-adjusting shielding structure set on the main light can automatically fit the shielding plate to the main light when holding the main light to avoid affecting the operation. When reinstalling the main light, the shielding plate can automatically rotate to shield the disinfectant. The design is ingenious and fully considers the convenience of medical staff's actual operation.

[0018] 4. The mounting base and the suspension rod adopt a magnetic mounting structure, which can not only ensure that the suspension rod will not be separated from the mounting base due to tension when wall-mounted, but also can be easily separated when needed. A wire reel is set in the mounting base, and the main light is directly connected to the wire in the wire reel through a cable, and the ring light is connected to the wire reel using a power terminal. This design allows the main light to continue to illuminate when used alone, and the wires can be automatically recovered when reinstalled. At the same time, the ring light only lights up when the main light is mounted to avoid affecting the concentrated lighting of the main light. The entire electrical connection structure is reasonably designed to ensure the stable operation of the device and the realization of different lighting modes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 11 The present invention provides a technical solution: a lighting device and method for otolaryngology care.

[0033] like Figure 1 , Figure 2As shown, the lighting device is a wall-mounted structure, including a wall-mounted base 1 for fixing on the wall, an adjusting bracket 2 is connected to the wall-mounted base 1, the adjusting bracket 2 is composed of a plurality of rods, and adjacent rods are connected by movable joints. The movable joints include rotating joints and universal joints, and self-locking structures such as damping are provided therein to realize free adjustment of the adjusting bracket 2 within a certain range. A hanging bracket 3 is connected to the end of the adjusting bracket 2, and a hanging bracket 4 is connected to the end of the hanging bracket 3. The lighting structure is detachably installed through the hanging bracket 4, thereby realizing free switching between hanging range lighting and handheld concentrated lighting.

[0034] like Figure 3 , Figure 4 As shown, the mounting seat 4 is a cylindrical structure, and the suspension rod 5 is inserted into the mounting seat 4 for connection. The lighting structure includes a main light 6 located in the middle and a ring light 7 surrounding the main light 6. The suspension rod 5 is connected to the top of the main light 6, and the main light 6 and the ring light 7 can be installed on the mounting seat 4, and a control rod 8 is fixedly connected to the bottom of the main light 6. When the main light 6 and the ring light 7 are connected to the mounting seat 4 and then to the adjustment bracket 2, the main light 6 and the ring light 7 can be driven to move by the control rod 8 and adjusted within a certain range to achieve more accurate lighting. At the same time, a clamp 9 is preset on the control rod 8, and a disposable protective cover can be put on the control rod 8 by the clamp 9 to avoid contamination of the control rod 8.

[0035] like Figure 5 As shown, the suspension rod 5 and the mounting seat 4 of the present invention adopt a magnetic installation structure, a limiting groove 10 is provided on the mounting seat 4, and a magnetic seat 11 is installed on the top of the limiting groove 10, and a ferromagnetic top plate 12 is fixedly connected to the top of the suspension rod 5. The magnetic seat 11 with strong magnetism is selected, and the magnetic force generated is sufficient to tightly adsorb the suspension rod 5 in the mounting seat 4. When the position of the main light 6 is adjusted by the control rod 8, the pulling force will not pull the suspension rod 5 out of the mounting seat 4, and the ferromagnetic top plate 12 is inserted into the mounting seat 4 through the limiting groove 10, which can play a role of limiting guide to prevent the installation of the suspension rod 5 from being misplaced. When sufficient force is provided to separate the suspension rod 5 and the mounting seat 4, the main light 6 and the ring light 7 can be removed from the mounting seat 4 for separate use, free from the limitation of the adjustment bracket 2, and further provide more precise lighting.

[0036] like Figure 5As shown, a switch is provided on the wall mount 1, which can be connected to the mains through an electric wire and routed along the direction of the adjustment bracket 2. A wire reel 13 is provided in the mounting seat 4. The electric wire is wound in the wire reel 13 and then passes through the wire reel 13. The main light 6 is directly connected to the wire through a cable 14. Therefore, when the switch is turned on, the main light 6 will light up. When the main light 6 is removed for use, the wire can be pulled out from the wire reel 13 to ensure that the main light 6 can continue to illuminate. When the main light 6 is reinstalled, a vortex spring is provided in the wire reel 13 to provide elastic force, and the wire can be recovered into the wire reel 13. The ring light 7 is connected to the wire reel 13 using the power terminal 15. Only when the boom 5 is installed in the mounting seat 4 will the ring light 7 light up. Therefore, the ring light 7 mainly plays the effect of range lighting. When the main light 6 is taken out for use, the ring light 7 will go out to avoid affecting the concentrated lighting of the main light 6.

[0037] like Fig. 9 , Fig.10 As shown, the control rod 8 arranged at the bottom of the main lamp 6 can conveniently adjust the position of the main lamp 6 when it is wall-mounted, but the control rod 8 is not conducive to the hand-held use of the main lamp 6. A pick-up seat 18 is arranged on the back of the main lamp 6 for hand-held operation of the main lamp 6. The main lamp 6 is fixedly connected with a ventilation box 16, and piston assemblies 17 are installed on both sides of the ventilation box 16. The pick-up seat 18 is connected to the piston assembly 17. Therefore, when the main lamp 6 is to be hand-held through the pick-up seat 18, the pressure generated can press the piston assembly 17 to compress the gas in the ventilation box 16. The ventilation box 16 is fixedly connected with an air cylinder 19, and a piston assembly 17 is movably installed in the air cylinder 19. The float rod 20, when the gas in the ventilation box 16 is compressed, the float rod 20 can move under the action of air pressure and rise from the air cylinder 19, and the float rod 20 is arranged below the ferromagnetic top plate 12, and a through hole 21 is arranged on the ferromagnetic top plate 12. When the float rod 20 rises, it can penetrate the ferromagnetic top plate 12 and press on the magnetic seat 11. The reaction force generated can make the suspension rod 5 and the hanging seat 4 overcome the magnetic force and separate. Since the reaction force is generated between the two, the adjustment bracket 2 will not move when the main lamp 6 is taken. After a certain distance of separation, the magnetic force between the magnetic seat 11 and the ferromagnetic top plate 12 is weakened, and the main lamp 6 can be completely taken down from the hanging seat 4.

[0038] like Figure 6-Figure 8 As shown, a ratchet plate 22 is fixedly mounted on the ferromagnetic top plate 12 of the present invention, and a disinfectant spraying structure and a corresponding pressing structure are provided on the mounting seat 4. When the main lamp 6 is reinstalled into the mounting seat 4 along with the suspension rod 5, the ratchet plate 22 can drive the pressing structure to make the disinfectant spraying structure spray disinfectant toward the position of the taking seat 18, thereby timely disinfecting the handheld part to avoid cross infection.

[0039] like Figure 6-Figure 8 As shown, the disinfectant spraying structure includes a mounting seat 23 arranged on the hanger 3, and a clamp 25 is arranged on the mounting seat 23. The disinfectant bottle 24 can be installed upside down through the mounting seat 23 and the clamp 25. A rubber plug 26 is arranged in the disinfectant bottle 24 to prevent the outflow of the disinfectant. At the same time, the disinfectant spraying structure includes a hanging seat 27 arranged on the wall hanging seat 1, and a pressing tube 28 is installed in the hanging seat 27. A nozzle 29 facing the ventilation box 16, the taking seat 18 and other parts is connected to the pressing tube 28. The pressing tube 28 and the nozzle 29 adopt a common air pressure nozzle structure. When it is pressed back and forth, the air therein can be squeezed out, and the air pressure causes the disinfectant to enter the nozzle 29 and spray out. At the same time, the pressing structure includes relying on the hanging seat The shaft seat 30 installed on 27 has a ratchet gear 31 rotatably installed in the shaft seat 30, and a push rod 32 is coaxially installed on the ratchet gear 31. There are at least three push rods 32 arranged in a ring, and an inclined seat 33 is fixedly connected to the pressing tube 28. When the hanging rod 5 is assembled into the hanging seat 4, the ratchet gear 31 rotates under the action of the ratchet plate 22, and the push rod 32 can rotate accordingly. The push rod 32 thereon acts on the inclined seat 33, so that it generates a force to press the pressing tube 28. Multiple push rods 32 can perform pressing work reciprocatingly, thereby realizing the spraying of disinfectant and completing the disinfection work in time. When the hanging rod 5 is pulled out from the hanging seat 4, the ratchet plate 22 and the ratchet gear 31 can be slightly deformed and misplaced, which will not cause the ratchet gear 31 and the push rod 32 to rotate.

[0040] like Fig.11 As shown, in order to prevent the disinfectant from falling on the medical staff and patients, a torsion spring seat 34 is installed at the rear of the main lamp 6, and the baffle 35 is rotatably installed through the torsion spring seat 34. The elastic force of the torsion spring can keep the baffle 35 in a state of being upright on the surface of the main lamp 6, so as to shield the sprayed disinfectant. Shrapnel 36 are arranged on both sides of the ventilation box 16. When holding the main lamp 6, the taking seat 18 is compressed toward the ventilation box 16, and the taking seat 18 can push the shrapnel 36 to deform the shrapnel 36. The bottom end of the shrapnel 36 is pressed on the baffle 35, so that the baffle 35 is rotated to fit on the main lamp 6, so as to avoid affecting the hand-holding action of the medical staff and ensure that the main lamp 6 is easier to hold and use. When the main lamp 6 is reinstalled, the taking seat 18 will be loosened, so that the float rod 20 will fall back, the suspension rod 5 can enter the hanging seat 4, and the baffle 35 can also rotate.

[0041] When the present invention is used: first, wall-mounted range lighting is performed, the main light 6 and the ring light 7 are connected to the mounting seat 4 through the suspension rod 5, and the disposable protective cover is installed on the control rod 8 through the clamp 9, and then the tension is applied through the control rod 8 to deform the adjustment bracket 2, drive the main light 6 and the ring light 7 to move, and adjust within a certain range. At this time, the main light 6 and the ring light 7 are turned on at the same time to perform range lighting, and the main light 6 can also be hand-held to perform fixed-point centralized lighting. When the main light 6 is hand-held through the taking seat 18, the taking seat 18 is first pressed to compress the gas in the air exchange box 16, so that the float rod 20 rises from the air cylinder 19. The magnetic base 11 is raised and pressed against the magnetic base 11 to generate a reaction force, thereby separating the suspension rod 5 from the mounting seat 4, and then completely removing the main lamp 6 from the mounting seat 4. At this time, only the main lamp 6 is turned on, and targeted local lighting of the patient can be performed. Finally, the used main lamp 6 is reinstalled on the adjustment bracket 2, and the suspension rod 5 on the main lamp 6 is aligned with the mounting seat 4 and inserted so that they are connected together under the action of magnetic force. At the same time, the pressing structure on the wall mounting seat 1 is driven by the ratchet plate 22 on the suspension rod 5, so that the disinfectant spraying structure sprays the disinfectant toward the position of the taking seat 18, and the hand-held part is disinfected in time for the next use.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
