Description

Technical Field

[0001] The present invention relates to the technical field of lighting devices, and particularly to a light-giving lighting device and method for otolaryngology nursing. Background Technique

[0002] Otolaryngology involves the diagnosis and treatment of diseases in the ear, nose, pharynx, larynx and their related head and neck regions. In otolaryngology nursing work, nursing staff need to provide comprehensive and meticulous care for patients. For example, during ear care, it may be necessary to clean the secretions in the external auditory canal and observe the condition of the tympanic membrane; in nasal care, the nasal cavity needs to be irrigated and the state of the nasal mucosa needs to be checked; laryngeal care may involve nebulization inhalation treatment and observation of laryngeal lesions, etc. Accurate nursing operations play a crucial role in the treatment effect of diseases, the rehabilitation process of patients and the prevention of complications. Therefore, a light-giving lighting device that can provide a clear lighting environment is very important.

[0003] Currently, in otolaryngology nursing work, the commonly used lighting devices mainly include head-mounted frontal mirrors and ordinary wall-mounted examination lights. The light intensity of the head-mounted frontal mirror is relatively low, while the ordinary wall-mounted examination light can provide relatively bright overall lighting and can be freely adjusted within a certain range, but its adjustment range has limitations and it is difficult to accurately focus on narrow and deep cavities such as the ear, nose and throat when necessary. When a detailed observation of a specific part is required, the ordinary examination light cannot meet the needs of local lighting, which may increase the operation difficulty for nursing staff due to poor light, and may even cause unnecessary injuries to patients due to unclear vision. In addition, during the use of the ordinary wall-mounted examination light, manual adjustment by medical staff is required, and the lamp is easily contaminated during the nursing process, and the lamp needs to be frequently disinfected. If the disinfection is not thorough, problems such as cross-infection may occur, bringing potential risks to patients. Summary of the Invention

[0004] The purpose of the present invention is to provide a light-giving lighting device and method for otolaryngology nursing, so as to achieve the purpose of enriching the usage scenarios and avoiding cross-infection, and to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A light-giving lighting device for otolaryngology nursing, including a wall-mounted seat fixed on the wall, and an adjustment bracket is connected to the wall-mounted seat, and a lighting structure is connected to the adjustment bracket. A hanging seat is installed on the adjustment bracket through a hanging rack, and the lighting structure is connected to the hanging seat through a suspension rod. The lighting structure includes a main lamp located in the middle and a ring lamp surrounding the main lamp;

[0006] The suspension rod and the hanging seat are limited and assembled through a magnetic adsorption hanging structure. This light-giving lighting device further includes:

[0007] The control rod is used to change the illumination positions of the main lamp and the ring lamp, and a disposable protective cover is installed on the control rod through a clamping part.

[0008] The handheld mechanism is used to hold the main lamp and to separate the hanging rod and the mounting base. The handheld mechanism is arranged on the main lamp and includes a movable holding base and a pneumatic floating rod controlled by the holding base. The floating rod can act on the mounting base.

[0009] The disinfectant spraying structure is used to disinfect the handheld mechanism, and the disinfectant spraying structure is driven by a pressing structure thereon. The pressing structure is driven unidirectionally by the action of assembling the hanging rod into the mounting base.

[0010] Preferably, an adjustable shielding structure is arranged on the main lamp, and the shielding structure includes:

[0011] A shielding plate is installed on the torsion spring seat of the main lamp, and the shielding plate is located below the handheld mechanism and can shield the disinfectant.

[0012] A shrapnel is obliquely installed on the main lamp, and the shrapnel can be pushed by the holding base to deform and push the shielding plate.

[0013] Preferably, a ventilation box is fixedly connected to the main lamp, piston components are installed on both sides of the ventilation box, the holding base is connected to the piston components, and an elastic member is connected to the piston components.

[0014] An air cylinder is fixedly connected to the ventilation box, the floating rod is movably installed in the air cylinder, and the floating rod can be lifted from the air cylinder by compressing the piston components through the holding base.

[0015] The floating rod can penetrate the ferromagnetic top plate and press on the magnetic attraction seat.

[0016] Preferably, the mounting base is of a cylindrical structure, the hanging rod is connected to the top of the main lamp, a limiting groove is arranged on the mounting base, and a magnetic attraction seat is installed at the top of the limiting groove.

[0017] The top end of the hanging rod is fixedly connected with a ferromagnetic top plate, and a ratchet plate is fixedly installed on the ferromagnetic top plate.

[0018] Preferably, a wire winding base is arranged in the mounting base, the main lamp is directly connected to the electric wire in the wire winding base through a cable, and the ring lamp is connected to the wire winding base by using an electrical connection terminal.

[0019] Preferably, the disinfectant spraying structure includes a mounting seat arranged on the hanging rack, a clamp is arranged on the mounting seat, the disinfectant bottle can be installed in an inverted manner through the mounting seat and the clamp, and a rubber stopper is arranged in the disinfectant bottle to prevent the disinfectant from flowing out.

[0020] Preferably, the disinfectant spraying structure further includes a hanging seat arranged on the wall-mounted seat, and a pressing tube is assembled in the hanging seat, and a spray head is connected to the pressing tube.

[0021] Preferably, the pressing structure includes a shaft seat mounted depending on the hanging seat, and a ratchet gear is rotatably mounted in the shaft seat, a push rod is coaxially mounted 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.

[0022] Preferably, at least three push rods are annularly arranged on the axle of the ratchet gear, and an inclined seat is fixedly connected to the pressing tube, and the inclined seat is on the rotation path of the push rod.

[0023] A lighting method for a light illumination device used in otolaryngology nursing, the lighting method includes the following steps:

[0024] S1, First, perform wall-mounted range lighting. Connect the main lamp and the ring lamp to the hanging seat through the hanging rod. Put on the disposable protective cover on the control rod through the clamping part. Then apply a pulling force through the control rod to deform the adjusting bracket, drive the main lamp and the ring lamp to move, and adjust within a certain range. At this time, the main lamp and the ring lamp are turned on simultaneously to perform range lighting;

[0025] S2, Hold the main lamp to perform fixed-point concentrated lighting. First, press the taking seat to compress the gas in the air exchange box, so that the floating rod rises from the air cylinder and presses against the magnetic attraction seat to generate a reaction force to separate the hanging rod from the hanging seat, and then completely take the main lamp off the hanging seat. At this time, only the main lamp is turned on to perform precise lighting of the patient's local area;

[0026] S3, Finally, reinstall the used main lamp on the adjusting bracket. Align the hanging rod on the main lamp and insert it into the hanging seat so that they are connected together under the action of magnetism. At the same time, drive the pressing structure on the wall-mounted seat through the ratchet plate on the hanging rod, so that the disinfectant spraying structure sprays disinfectant towards the position of the taking seat to disinfect the handheld part in time for the next use.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. Enrich the lighting methods to meet the needs of different scenarios. The present invention provides two lighting methods: wall-mounted range lighting and hand-held main lamp fixed-point concentrated lighting. When performing wall-mounted lighting, the main lamp and the ring lamp are turned on simultaneously, and the positions of the main lamp and the ring lamp can be adjusted through the control rod to achieve range lighting within a certain range, which is suitable for general inspection and nursing scenarios. When precise lighting of the patient's local area is required, the main lamp can be easily disassembled from the hanging seat and used alone, breaking away from the limitation of the adjusting bracket, meeting the need for detailed observation of specific parts such as the narrow and deep cavities of the ear, nose, and throat, greatly enriching the usage scenarios, and improving the pertinence and practicality of lighting.

[0029] 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.

[0030] 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.

[0031] 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 implementation manners

[0044] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments. It should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0045] Please refer to Figures 1 to 11 , the present invention provides a technical solution: a light illumination device and method for otolaryngology nursing.

[0046] As Figure 1 , Figure 2As shown in the figure, the light supply and illumination device has a wall-mounted structure, including a wall-mounted base 1 for fixing on the wall. An adjustment bracket 2 is connected to the wall-mounted base 1. The adjustment bracket 2 is composed of multiple rods, and adjacent rods are connected by movable joints. The movable joints include rotating joints and universal joints, and a damping self-locking structure is provided therein to realize the free adjustment of the adjustment bracket 2 within a certain range. The end of the adjustment bracket 2 is connected to a hanging bracket 3, and the end of the hanging bracket 3 is connected to a hanging mount 4. The lighting structure is detachably installed through the hanging mount 4, so as to realize the free switching between the hanging range illumination and the handheld focused illumination.

[0047] As Figure 3 , Figure 4 shown, the hanging mount 4 has a cylindrical structure. A suspension rod 5 is inserted into the hanging mount 4 for connection. The lighting structure includes a main lamp 6 in the middle and a ring lamp 7 surrounding the main lamp 6. The suspension rod 5 is connected to the top of the main lamp 6, and the main lamp 6 and the ring lamp 7 can be installed on the hanging mount 4. And a control rod 8 is fixedly connected to the bottom of the main lamp 6. When the main lamp 6 and the ring lamp 7 are connected to the hanging mount 4 and then connected to the adjustment bracket 2, the main lamp 6 and the ring lamp 7 can be driven to move by the control rod 8 and adjusted within a certain range to achieve more accurate light supply and illumination. At the same time, a clamping member 9 is preset on the control rod 8, and a disposable protective sleeve can be sleeved on the control rod 8 through the clamping member 9 to avoid contaminating the control rod 8.

[0048] As Figure 5 shown, the suspension rod 5 and the hanging mount 4 of the present invention adopt a magnetic adsorption installation structure. A limiting groove 10 is provided on the hanging mount 4, and a magnetic adsorption seat 11 is installed at the top of the limiting groove 10. The top end of the suspension rod 5 is fixedly connected with a ferromagnetic top plate 12. A strongly magnetic magnetic adsorption seat 11 is selected, and the generated magnetic force is sufficient to tightly adsorb the suspension rod 5 in the hanging mount 4. When the position of the main lamp 6 is adjusted by the control rod 8, the pulling force will not pull the suspension rod 5 out of the hanging mount 4. And the ferromagnetic top plate 12 is inserted into the hanging mount 4 through the limiting groove 10, which can play a role of limiting and guiding to prevent the misalignment of the installation of the suspension rod 5. When a force sufficient to separate the suspension rod 5 and the hanging mount 4 is provided, the main lamp 6 and the ring lamp 7 can be detached from the hanging mount 4 and used separately, breaking away from the restriction of the adjustment bracket 2 to further provide more accurate illumination.

[0049] As Figure 5As shown, a switch is provided on the wall-mounted base 1, which can be connected to the mains through a wire and routed along the direction of the adjustment bracket 2. A wire-winding base 13 is provided in the hanging base 4, and the wire is wound in the wire-winding base 13 and then passes through the wire-winding base 13. The main lamp 6 is directly connected to the wire through the cable 14. Therefore, when the switch is turned on, the main lamp 6 will light up. When the main lamp 6 is removed for use, the wire can be pulled out from the wire-winding base 13 to ensure that the main lamp 6 can continue to provide illumination. When the main lamp 6 is reinstalled, a volute spring is provided in the wire-winding base 13 to provide elastic force, and the wire can be retracted into the wire-winding base 13. The ring lamp 7 is connected to the wire-winding base 13 by the power connection terminal 15. The ring lamp 7 will only light up when the hanging rod 5 is installed in the hanging base 4. Therefore, the ring lamp 7 mainly serves the effect of providing area illumination. When the main lamp 6 is taken for use, the ring lamp 7 will go out to avoid affecting the concentrated illumination of the main lamp 6.

[0050] As Figure 9 , Figure 10 shown, when the control rod 8 provided at the bottom of the main lamp 6 is used for wall mounting, the position of the main lamp 6 can be conveniently adjusted. However, the control rod 8 is not conducive to the hand-held use of the main lamp 6. A gripping base 18 is provided on the back of the main lamp 6 for hand-held operation of the main lamp 6. A ventilation box 16 is fixedly connected to the main lamp 6, and piston assemblies 17 are installed on both sides of the ventilation box 16. The gripping base 18 is connected to the piston assemblies 17. Therefore, when preparing to hold the main lamp 6 through the gripping base 18, the pressure generated can press the piston assemblies 17 to compress the gas in the ventilation box 16. A cylinder 19 is fixedly connected to the ventilation box 16, and a floating rod 20 is movably installed in the cylinder 19. When the gas in the ventilation box 16 is compressed, the floating rod 20 can move under the action of air pressure and rise from the cylinder 19. The floating rod 20 is arranged below the ferromagnetic top plate 12, and a through hole 21 is provided on the ferromagnetic top plate 12. When the floating rod 20 rises, it can penetrate the ferromagnetic top plate 12 and then press on the magnetic attraction seat 11. The reaction force generated can cause the hanging rod 5 and the hanging base 4 to separate against the magnetic force. Since the reaction force is generated between the two, the adjustment bracket 2 will not move when the main lamp 6 is taken. After separating a certain distance, the magnetic force between the magnetic attraction seat 11 and the ferromagnetic top plate 12 weakens, and the main lamp 6 can be completely taken down from the hanging base 4.

[0051] As Figures 6 - 8 shown, a ratchet plate 22 is fixedly installed on the ferromagnetic top plate 12 of the present invention, and a disinfectant spraying structure and a corresponding pressing structure are provided on the hanging base 4. When the main lamp 6 is reinstalled into the hanging base 4 along with the hanging rod 5, the ratchet plate 22 can drive the pressing structure to make the disinfectant spraying structure spray disinfectant towards the position of the gripping base 18 to disinfect the hand-held part in time and avoid cross-infection.

[0052] AsFigures 6 - 8 As shown in the figure, the disinfectant spraying structure includes a mounting base 23 provided on the hanger 3. A clamp 25 is provided on the mounting base 23. Through the mounting base 23 and the clamp 25, the disinfectant bottle 24 can be installed in an inverted manner. A rubber stopper 26 is provided in the disinfectant bottle 24 to prevent the outflow of the disinfectant. At the same time, the disinfectant spraying structure includes a suspension seat 27 provided on the wall-mounted seat 1. A pressing tube 28 is assembled in the suspension seat 27. A spray head 29 facing parts such as the ventilation box 16 and the taking seat 18 is connected to the pressing tube 28. The pressing tube 28 and the spray head 29 adopt a common pneumatic spray head structure. When it is pressed reciprocally, the air inside can be squeezed out, and the air pressure causes the disinfectant to enter the spray head 29 and be sprayed out. At the same time, the pressing structure includes a shaft seat 30 mounted depending on the suspension seat 27. A ratchet gear 31 is rotatably installed in the shaft seat 30. A push rod 32 is coaxially installed on the ratchet gear 31. At least three push rods 32 are annularly arranged. A slant 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 slant seat 33 to generate a force to press the pressing tube 28. The multiple push rods 32 can perform the pressing work reciprocally, so as to realize the spraying of the disinfectant and complete 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 misaligned, and the ratchet gear 31 and the push rod 32 will not rotate.

[0053] As Figure 11 shown in the figure, in order to prevent the disinfectant from falling on medical staff and patients, a torsion spring seat 34 is installed at the rear of the main lamp 6. The shielding plate 35 is rotatably installed through the torsion spring seat 34. The elastic force of the torsion spring can keep the shielding plate 35 in a state perpendicular to the surface of the main lamp 6, and can block the sprayed disinfectant. Elastic pieces 36 are provided on both sides of the ventilation box 16. When holding the main lamp 6 by hand, the taking seat 18 is compressed towards the ventilation box 16. The taking seat 18 can push the elastic pieces 36, causing the elastic pieces 36 to deform. The bottom end of the elastic piece 36 presses on the shielding plate 35, causing the shielding plate 35 to rotate and fit on the main lamp 6, avoiding affecting the hand-holding action of medical staff and ensuring that the main lamp 6 is more convenient to hold and use. When reinstalling the main lamp 6, the taking seat 18 will be released, causing the floating rod 20 to fall back, the hanging rod 5 can enter the hanging seat 4, and the shielding plate 35 can also rotate back.

[0054] 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.

[0055] 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.
