Description

Technical Field

[0001] This utility model relates to the technical field of nasal plug fixation devices, specifically a nasal plug fixation device for oxygen inhalation. Background Technology

[0002] The Department of Nephrology is a clinical department set up in hospitals at all levels to diagnose and treat kidney diseases. Kidney diseases are common and frequently occurring diseases, including acute glomerulonephritis, rapidly progressive glomerulonephritis, chronic glomerulonephritis, nephrotic syndrome, IgA nephropathy, interstitial nephritis, renal tubular acidosis, acute renal failure, and chronic renal failure. In hospital clinical nursing work, critically ill patients with these diseases need oxygen inhalation to correct hypoxia. Oxygen inhalation requires the use of an oxygen inhalation tube, and nasal cannula fixation devices play a crucial role in preventing the oxygen inhalation tube from falling out.

[0003] A nasal prosthesis fixing device for oxygen inhalation, disclosed in publication number CN220344888U, allows a person to place the nasal prosthesis over the patient's nose and insert the nasal prosthesis tube into the patient's nostril by setting up the nasal prosthesis tube and fastening bolt. Then, by rotating the fastening bolt, it moves into the nasal prosthesis and, together with the nasal prosthesis tube, presses against the patient's nasal wing, thereby achieving a fixing effect on the nasal prosthesis. This avoids the discomfort caused by constricting the patient's head, and the fixing effect is good, preventing the prosthesis from falling off during the person's head turning, which would make it difficult for the patient to inhale oxygen. This improves the stability and safety during use. Furthermore, the fastening component can fix the oxygen delivery tube inserted into the nasal prosthesis tube, thereby preventing the oxygen delivery tube from falling off. At the same time, it keeps the oxygen delivery tube flush with the clamping position when inserted into the nasal prosthesis tube, thereby preventing the oxygen delivery tube from bending and causing obstruction of oxygen delivery.

[0004] However, this nasal plug fixation device for oxygen inhalation has the following disadvantages:

[0005] (1) The oxygen inhalation nasal plug fixing device has a weak function of easy disassembly and assembly. Since the fastening frame in the device is fixed and difficult to disassemble, subsequent maintenance is more troublesome, which reduces the efficiency of subsequent device maintenance.

[0006] (2) The oxygen inhalation nasal plug fixing device is not very convenient for adjusting the position of one side of the oxygen tube. Since only one side of the oxygen tube needs to be adjusted, the device can only move both pressure plates at the same time, causing the position of the other side of the oxygen tube to easily shift and requiring constant adjustment. Utility Model Content

[0007] The purpose of this invention is to provide a nasal plug fixing device for oxygen inhalation, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a nasal plug fixing device for oxygen inhalation, comprising: a base plate, a mounting assembly, and a clamping assembly. A limiting groove is formed on the top of the base plate, a limiting slider is slidably connected inside the limiting groove, a limiting block is fixedly connected to the outer surface of the limiting slider, a limiting plate is fixedly connected to the top of the limiting slider, an insert is inserted inside the limiting slider, a pull rod is fixedly connected to one end of the insert, a first spring is sleeved on the outer surface of the pull rod, and a circular plate is fixedly connected to one end of the first spring.

[0009] An adjusting rod is slidably connected inside the limiting plate. A second spring is sleeved on the outer surface of the adjusting rod. A clamping plate is fixedly connected to the bottom of the adjusting rod. A rectangular slider is fixedly connected to the side of the clamping plate. A connecting plate is slidably connected to the outer surface of the adjusting rod. A connecting block is threadedly connected to the top of the adjusting rod. A connecting rod is fixedly connected to the top of the connecting plate. A top plate is fixedly connected to the top of the connecting rod.

[0010] Optionally, a circular slot is provided on the side of the circular plate, and the outer surface of the pull rod is slidably connected to the inner wall of the circular slot. When the pull rod is pulled, the surface of the pull rod slides inside the circular slot, and the circular slot limits the surface of the pull rod.

[0011] Optionally, one end of the second spring is fixedly connected to the inner top wall of the limiting plate, and the other end of the spring is fixedly connected to the top of the clamping plate. Through the connection between the second spring, the limiting plate, and the clamping plate, the limiting plate supports and fixes one end of the second spring. When the second spring extends or retracts, it will drive the clamping plate to move together.

[0012] Optionally, the inner wall of the limiting plate is provided with a rectangular sliding groove, and the outer surface of the rectangular slider is slidably connected to the inner wall of the rectangular sliding groove. When the clamping plate moves, it will drive the rectangular slider to slide inside the rectangular sliding groove. At the same time, the rectangular sliding groove limits the rectangular slider, and the rectangular slider limits the movement position of the clamping plate.

[0013] Optionally, a limiting slot is provided on the inner side wall of the base plate, and the outer surface of the limiting block is engaged with the inside of the limiting slot. When the limiting slider slides to the point where the limiting block is engaged with the inside of the limiting slot, the limiting slot limits the limiting block, so that the position of the limiting block is stabilized inside the limiting slot, thereby stabilizing the position of the limiting plate.

[0014] Optionally, a fixing slot is provided on one side of the base plate, and the outer surface of the pull rod is slidably connected to the inner wall of the fixing slot. When the pull rod is pulled, the fixing slot limits the movement position of the pull rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This nasal plug fixing device for oxygen inhalation, through the setting of the installation components, when in use, pulling the pull rod causes the first spring to retract, and the circular plate supports and fixes the first spring, sliding the limiting slider into the limiting groove. When the limiting block is engaged in the slot on the inner wall of the limiting groove, the pull rod is released. At this time, the first spring rebounds and causes the limiting block to insert into the limiting slider, fixing the position of the limiting slider. This completes the installation of the limiting plate, achieving the effect of improving the efficiency of fastening device assembly and disassembly, avoiding the situation where the fastening frame in the device is fixed and difficult to disassemble, making subsequent maintenance more troublesome and reducing the efficiency of subsequent device maintenance.

[0017] 2. This nasal plug fixing device for oxygen inhalation, through the setting of the clamping assembly, allows for the following operation: pulling the top plate moves the connecting rod and connecting plate, which in turn moves the adjusting rod, causing the second spring to contract. The contraction of the second spring then moves the clamping plate. After the oxygen delivery tube is positioned, releasing the top plate causes the second spring to rebound, clamping the oxygen delivery tube and maintaining its stable position. Rotating one of the two connecting blocks disengages it from the top of the adjusting rod, allowing for the pulling of a single adjusting rod to move a single clamping plate. This adjusts the position of one side of the oxygen delivery tube, improving the efficiency of subsequent adjustments and avoiding the situation where, if only one side of the oxygen delivery tube needs adjustment, the device can only move both plates simultaneously, leading to the other side's oxygen delivery tube easily shifting and requiring continuous adjustment.

[0023] 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.

[0024] Please see Figures 1-4 As shown, this utility model provides a technical solution: a nasal plug fixing device for oxygen inhalation, comprising: a base plate 1, a mounting assembly 2, and a clamping assembly 3. A limiting groove 201 is formed on the top of the base plate 1. A limiting slider 202 is slidably connected inside the limiting groove 201. A limiting block 203 is fixedly connected to the outer surface of the limiting slider 202. A limiting plate 204 is fixedly connected to the top of the limiting slider 202. An insert block 205 is inserted inside the limiting slider 202. A pull rod 206 is fixedly connected to one end of the insert block 205. The outer surface of the pull rod 206 is sleeved with... A first spring 207 is connected, and a circular plate 208 is fixedly connected to one end of the first spring 207. Pulling the pull rod 206 causes the first spring 207 to retract, and the circular plate 208 supports and fixes the first spring 207. The limiting slider 202 is slid into the limiting groove 201. When the limiting block 203 is engaged in the slot on the inner wall of the limiting groove 201, the pull rod 206 is released. At this time, the first spring 207 rebounds and causes the limiting block to insert into the limiting slider 202, so that the position of the limiting slider 202 is fixed, thereby completing the installation of the limiting plate 204.

[0025] An adjusting rod 301 is slidably connected inside the limiting plate 204. A second spring 302 is sleeved on the outer surface of the adjusting rod 301. A clamping plate 303 is fixedly connected to the bottom of the adjusting rod 301. A rectangular slider 304 is fixedly connected to the side of the clamping plate 303. A connecting plate 305 is slidably connected to the outer surface of the adjusting rod 301. A connecting block 306 is threadedly connected to the top of the adjusting rod 301. A connecting rod 307 is fixedly connected to the top of the connecting plate 305. A top plate 308 is fixedly connected to the top of the connecting rod 307. Pulling the top plate 308 moves the connecting rod 307 and the connecting plate. Move 305, and the moving of the connecting plate 305 will drive the adjusting rod 301 to move, which in turn will cause the second spring 302 to contract. The contraction of the second spring 302 will drive the clamping plate 303 to move. After the oxygen tube is placed, release the top plate 308. At this time, the second spring 302 will rebound and drive the clamping plate 303 to clamp the oxygen tube, keeping the position of the oxygen tube stable. Rotate one of the two connecting blocks 306 to disengage the connecting block 306 from the top of the adjusting rod 301. Pull one adjusting rod 301 alone to drive one clamping plate 303 to move, thereby adjusting the position of the oxygen tube on one side.

[0026] A circular slot 4 is provided on the side of the circular plate 208. The outer surface of the pull rod 206 is slidably connected to the inner wall of the circular slot 4. When the pull rod 206 is pulled, the surface of the pull rod 206 slides inside the circular slot 4, and the circular slot 4 limits the surface of the pull rod 206.

[0027] One end of the second spring 302 is fixedly connected to the inner top wall of the limiting plate 204, and the other end of the spring is fixedly connected to the top of the clamping plate 303. When the clamping plate 303 moves, it will drive the rectangular slider 304 to slide inside the rectangular groove 5. At the same time, the rectangular groove 5 limits the rectangular slider 304, and the rectangular slider 304 limits the movement position of the clamping plate 303.

[0028] The inner sidewall of the limiting plate 204 is provided with a rectangular slide groove 5. The outer surface of the rectangular slider 304 is slidably connected to the inner sidewall of the rectangular slide groove 5. When the clamping plate 303 moves, it will drive the rectangular slider 304 to slide inside the rectangular slide groove 5. At the same time, the rectangular slide groove 5 limits the rectangular slider 304, and the rectangular slider 304 limits the movement position of the clamping plate 303.

[0029] The inner sidewall of the base plate 1 is provided with a limiting groove 6. The outer surface of the limiting block 203 is engaged with the inside of the limiting groove 6. When the limiting slider 202 slides to the point where the limiting block 203 is engaged with the inside of the limiting groove 6, the limiting groove 6 limits the limiting block 203, so that the position of the limiting block 203 is stabilized inside the limiting groove 6, thereby stabilizing the position of the limiting plate 204.

[0030] A fixing slot is provided on one side of the base plate 1. The outer surface of the pull rod 206 is slidably connected to the inner wall of the fixing slot. When the pull rod 206 is pulled, the fixing slot limits the movement position of the pull rod 206.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: Pulling the lever 206 causes the first spring 207 to retract, and the circular plate 208 supports and fixes the first spring 207, sliding the limiting slider 202 into the limiting groove 201. When the limiting block 203 engages in the groove on the inner wall of the limiting groove 201, the lever 206 is released. At this time, the first spring 207 rebounds, causing the limiting block to insert into the limiting slider 202, fixing the position of the limiting slider 202. This completes the installation of the limiting plate 204. Pulling the top plate 308 moves the connecting rod 307 and the connecting plate 305, connecting... The movement of the connecting plate 305 causes the adjusting rod 301 to move, which in turn causes the second spring 302 to contract. The contraction of the second spring 302 causes the clamping plate 303 to move. After the oxygen delivery tube is placed, the top plate 308 is released. At this time, the second spring 302 rebounds and causes the clamping plate 303 to clamp the oxygen delivery tube, keeping the position of the oxygen delivery tube stable. Rotate one of the two connecting blocks 306 to disengage the connecting block 306 from the top of the adjusting rod 301. Pull one adjusting rod 301 alone to move one clamping plate 303 alone, thereby adjusting the position of the oxygen delivery tube on one side.

[0033] Second step: When the pull rod 206 is pulled, the surface of the pull rod 206 slides inside the circular slot 4. At the same time, the circular slot 4 limits the surface of the pull rod 206. When the clamping plate 303 moves, it will drive the rectangular slider 304 to slide inside the rectangular slide groove 5. At the same time, the rectangular slide groove 5 limits the rectangular slider 304. The rectangular slider 304 limits the movement position of the clamping plate 303. When the limiting slider 202 slides until the limiting block 203 is inserted into the limiting slot 6, the limiting slot 6 limits the limiting block 203, so that the position of the limiting block 203 is stable inside the limiting slot 6, thereby stabilizing the position of the limiting plate 204. When the pull rod 206 is pulled, the fixing slot limits the movement position of the pull rod 206.
