Description

Technical Field

[0001] This invention relates to the field of nasal catheter fixation technology, specifically to a device for fixing intranasal catheters after surgery. Background Technology

[0002] After surgery, the tubes inserted into the nasal cavity are mainly used to drain gastric contents, reduce gastrointestinal pressure, or provide nutritional support, and usually need to be left in place for 1-3 days. When using the catheter, a fixation device is required to secure it. The catheter fixation device is a medical device used to support and fix the nasal catheter, mainly to maintain the nasal passage open, prevent the catheter from shifting or falling out, and promote postoperative recovery.

[0003] CN117547713A discloses a postoperative nasal catheter fixation device for esophageal cancer patients, specifically relating to the field of catheter fixation technology. It includes a nasal mask assembly worn on the outside of the patient's nose, secured to the nose by a top fixing component. The nasal mask assembly comprises a nose-shaped mask covering the outside of the patient's nose, with a nasal mask support pad fixed at the bottom of the inside. The support pad has two side-by-side tubular holes, one of which houses a connecting hose. The tip of the connecting hose communicates with a catheter inserted into the patient's nasal cavity. This invention, by designing the nasal mask in the shape of a nose, allows it to directly cover the outside of the patient's nose, thus minimizing the overall size of the invention. This allows the limiting mechanism to fix the tip of the connecting hose and the catheter in the patient's nasal cavity without affecting the patient's normal head or body turning.

[0004] The existing technology has the following shortcomings: the existing catheter fixation device cannot easily expand the nasal cavity when fixing the catheter, which makes it easy for the catheter to be blocked when directly inserted. This can easily cause damage to the inner wall of the nasal cavity during the insertion process. At the same time, the catheter cannot be quickly fixed after insertion, which makes it easy for the catheter to fall out of the nasal cavity, thus affecting the patient's postoperative recovery. Summary of the Invention

[0005] The purpose of this invention is to provide a postoperative nasal catheter fixation device for patients. The distance between the four dilators can be adjusted by the operation of the driving component, so that the four dilators can expand the nasal cavity. The fixing sleeve can fix the catheter, and the clamping clamp can clamp and limit the two fixing sleeves, so that the catheter can remain stable inside the nasal cavity, thereby solving the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a postoperative nasal catheter fixation device for patients, comprising a binding mechanism, and further comprising:

[0007] The fixing mechanism located at the bottom inside the binding mechanism, the conduit inside the fixing mechanism, and the extension mechanism outside the conduit;

[0008] The fixing mechanism includes a mounting plate, two fixing sleeves are movably inserted into the inner side of the mounting plate, the two fixing sleeves are movably sleeved on the outer side of the guide tube, a fixing groove is opened on the bottom outer side of the two fixing sleeves, a clamping hoop is sleeved on the outer side of the two fixing grooves, and a fastening pin is provided between the two clamping hoopes.

[0009] The expansion mechanism includes a driving component, which is disposed on the outside of the mounting plate. The output end of the driving component is provided with four expansion plates, which are disposed on the top outside of the fixed sleeve plate.

[0010] Preferably, the binding mechanism includes a protective cover, and a support pad is fixedly installed at the bottom of the protective cover. The support pad is movably sleeved on the outer side of the bottom of the mounting plate.

[0011] Preferably, binding straps are fixedly installed at both ends of the protective cover, and Velcro is fixedly installed on the side of each binding strap away from the protective cover.

[0012] Preferably, the driving component includes a movable sleeve plate, which is sleeved on the outside of the guide tube and located below the clamping hoop. Traction plates are rotatably installed around the movable sleeve plate.

[0013] Preferably, each of the four traction plates has a movable seat rotatably mounted on its top, and the bottom of the mounting plate has four first movable slots at equal intervals, with the outer wall of the movable seat slidably connected to the inner wall of the adjacent first movable slot.

[0014] Preferably, a connecting rod is fixedly installed at one end of the movable seat, and the end of the connecting rod away from the movable seat passes through the inner wall of the first movable groove and is fixedly installed with a connecting plate. The top of the mounting plate has four second movable grooves at equal intervals.

[0015] Preferably, a slider is fixedly installed at the bottom of the expansion plate, the outer wall of the slider is slidably connected to the inner wall of the adjacent second movable groove, and a movable rod that penetrates the inner wall of the second movable groove is fixedly installed at one end of the slider, with the end of the movable rod away from the slider being fixedly connected to the connecting plate.

[0016] Preferably, the bottom inner side of the expansion plate is provided with a snap-fit ​​groove, which is movably snapped onto the outer side of the top of the fixed sleeve plate, and the four expansion plates together form a conical structure.

[0017] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0018] 1. By installing the mounting plate to the bottom of the protective cover, and then using Velcro and binding straps to install the protective cover to the outside of the patient's nasal bridge, the driving component moves the four expansion plates. The distance between the four expansion plates can be adjusted so that the four expansion plates can expand the nasal cavity. Then, the fixing sleeve is inserted into the inside of the mounting plate to fix the catheter. Then, the clamping clamp is used to clamp and fix the bottom of the fixing sleeve, which can prevent the catheter from moving inside the fixing sleeve, thus keeping the catheter stable inside the nasal cavity, which is beneficial to the patient's postoperative recovery.

[0019] 2. By moving the movable sleeve up and down, and through the traction action of the traction plate, the movable seat can be moved along the inner wall of the adjacent first movable groove. Then, through the connection of the connecting rod, connecting plate and movable rod, the slider can be moved along the inner wall of the adjacent second movable groove. This allows the distance between the four expansion plates to be adjusted. The expansion plates can expand the nasal cavity. At the same time, the locking groove can lock and fix the fixed sleeve to prevent it from moving and ensure the stability of the catheter.

[0020] 3. By installing the mounting plate inside the support pad at the bottom of the protective cover, the diameter of the mounting plate is larger than the size of the patient's nostrils, which makes it convenient for medical staff to install and replace the fixation mechanism and the expansion mechanism. The conical expansion plate can stably expand the patient's nasal cavity, ensuring that the catheter can be stably inserted into the patient's nasal cavity from the four inner expansion sides.

[0034] This invention provides, for example Figure 1 The illustrated postoperative nasal catheter fixation device includes a binding mechanism 1, and further includes:

[0035] The fixing mechanism 2, the catheter 3 inside the fixing mechanism 2, and the expansion mechanism 4 outside the catheter 3 are located at the bottom inner side of the binding mechanism 1. The binding mechanism 1 can fix the device to the patient's head and bridge of the nose. The expansion mechanism 4 can expand the patient's nasal cavity, which can prevent the insertion of the catheter 3 from causing damage to the inside of the nasal cavity. The fixing mechanism 2 can fix the catheter 3, so that the catheter 3 can remain stable in the patient's nasal cavity.

[0036] To facilitate securing catheter 3 and prevent it from dislodging from the nasal cavity, such as... Figure 1-3 and Figure 5As shown, the fixation mechanism 2 includes a mounting plate 201. Two fixing sleeves 202 are movably inserted into the inner side of the mounting plate 201. The two fixing sleeves 202 are movably sleeved on the outer side of the catheter 3. Fixing grooves 203 are opened on the outer bottom of the two fixing sleeves 202. Clamping clamps 204 are sleeved on the outer side of the two fixing grooves 203. A fastening pin 205 is provided between the two clamping clamps 204. The mounting plate 201 is installed on the inner bottom of the binding mechanism 1. The two fixing sleeves 202 are inserted into the inner side of the mounting plate 201. Then, the catheter 3 is inserted into the inner side of the two fixing sleeves 202. The catheter 3 can be clamped by the two fixing sleeves 202. Then, the two clamping clamps 204 are sleeved on the outer bottom of the fixing sleeves 202 so that they can be inserted into the inner wall of the adjacent fixing grooves 203. Then, the fastening pin 205 can be used to connect the two clamping clamps 204, so that the catheter 3 can remain stable inside the nasal cavity, which can prevent the catheter 3 from falling out of the nasal cavity, thereby ensuring the patient's postoperative recovery effect.

[0037] To facilitate the insertion of catheter 3 into the patient's nasal cavity, such as... Figure 1-3 and Figure 6-7 As shown, the expansion mechanism 4 includes a driving component, which is located on the outside of the mounting plate 201. The output end of the driving component is provided with four expansion plates 408, which are located on the top outside of the fixed sleeve plate 202. When the driving component is working, it can drive the four expansion plates 408 to move on the top of the mounting plate 201. The distance between the four expansion plates 408 can be adjusted so that the four expansion plates 408 can expand the patient's nasal cavity. At the same time, the conical expansion plates 408 can fully fit the inner wall of the nasal cavity, so that the catheter 3 can easily pass through the inside of the expansion plates 408. This allows the catheter 3 to be quickly inserted into the patient's nasal cavity, avoiding damage to the nasal cavity when the catheter 3 is inserted. This allows medical staff to insert or remove the catheter 3 stably and quickly.

[0038] To ensure the device can be stably fixed to the patient's nasal bridge, such as Figure 1-4 As shown, the binding mechanism 1 includes a protective cover 101. A support pad 102 is fixedly installed at the bottom of the protective cover 101. The support pad 102 is movably sleeved on the outer side of the bottom of the mounting plate 201. Binding straps 103 are fixedly installed at both ends of the protective cover 101. Velcro 104 is fixedly installed on the side of the two binding straps 103 away from the protective cover 101. The binding straps 103 are passed around the back of the patient's head from below the ear, and then the two binding straps 103 are connected and fixed by the Velcro 104, so that the protective cover 101 can be sleeved on the outside of the patient's nose bridge, and the support pad 102 is positioned at the patient's nostrils. The Velcro 104 and binding straps 103 can prevent the protective cover 101 from falling off the outside of the nose bridge, so that it can stably fix the catheter 3.

[0039] To stably drive the expansion board 408 to expand or contract, such as Figure 2-3 and Figure 5-7 As shown, the driving component includes a movable sleeve 401, which is sleeved on the outside of the guide tube 3 and positioned below the clamping hoop 204. Traction plates 402 are rotatably mounted around the movable sleeve 401, and movable seats 403 are rotatably mounted on the top of each of the four traction plates 402. Four first movable slots 206 are evenly spaced at the bottom of the mounting plate 201. The outer wall of the movable seat 403 is slidably connected to the inner wall of the adjacent first movable slot 206. A connecting rod 404 is fixedly mounted at one end of the movable seat 403. One end of the connecting rod 404 away from the movable seat 403 passes through the inner wall of the first movable groove 206 and is fixedly installed with a connecting plate 405. The top of the mounting plate 201 has four second movable grooves 207 at equal intervals. The bottom of the expansion plate 408 is fixedly installed with a slider 407. The outer wall of the slider 407 is slidably connected to the inner wall of the adjacent second movable groove 207. One end of the slider 407 is fixedly installed with a movable rod 406 that passes through the inner wall of the second movable groove 207. The end of the movable rod 406 away from the slider 407 is fixedly connected to the connecting plate 405.

[0040] By pushing the movable sleeve 401 upwards to move it outside the catheter 3, the traction plate 402 can drive the four movable seats 403 to move along the inner walls of the four first movable grooves 206. This allows the connecting rod 404 to push the connecting plate 405 to move outwards from the mounting plate 201. The movement of the connecting plate 405 can drive the movable rod 406 to move, allowing the slider 407 to move along the inner wall of the adjacent second movable groove 207. This, in turn, can drive the four expanding plates 408 to move outwards, thus expanding the patient's nasal cavity and facilitating the insertion of the catheter 3.

[0041] To ensure the stability of the fixing sleeve 202 inside the mounting plate 201, such as Figure 2-3 and Figure 5-7 As shown, a snap-fit ​​groove 409 is provided on the bottom inner side of the expansion plate 408. The snap-fit ​​groove 409 is movably snapped onto the outer top of the fixed sleeve plate 202. The four expansion plates 408 together form a conical structure. The conical expansion plates 408 can expand the nasal cavity. The snap-fit ​​groove 409 on the inner side of the expansion plate 408 is snapped onto the outer top of the fixed sleeve plate 202, which can limit the fixed sleeve plate 202 and prevent the fixed sleeve plate 202 from moving inside the mounting plate 201.

[0042] The specific implementation method is as follows: When inserting a cannula into the patient's nasal cavity, the mounting plate 201 is installed inside the support pad 102 at the bottom of the protective cover 101. Then, the protective cover 101 is slipped onto the outside of the patient's nasal bridge. Two binding straps 103 are then wrapped around the back of the head from below the patient's ears and secured using two Velcro straps 104. This ensures the protective cover 101 is stably fitted onto the outside of the nasal bridge. The fixing plate 202 is then inserted into the inside of the mounting plate 201. Two clamping clamps 204 are then slipped onto the outside of the fixing plate 202, allowing them to be inserted into two fixing slots 203. Finally, fastening pins 205 are used to secure the two clamping clamps 204. The catheter 3 passes through the inside of the movable sleeve 401 and is inserted into the inside of the two fixed sleeves 202. Then, by pushing the movable sleeve 401 upward, it moves upward outside the catheter 3. Under the traction of the four traction plates 402, the four movable seats 403 can move outward along the inner wall of the four first movable grooves 206. This allows the connecting rod 404 to push the adjacent connecting plate 405 to move outward toward the outside of the mounting plate 201. The movement of the connecting plate 405 can drive the slider 407 to move along the inner wall of the adjacent second movable groove 207. This can then drive the four expanding plates 408 to expand outward, allowing them to expand the patient's nasal cavity and preventing the catheter 3 from being directly inserted into the patient's nasal cavity and causing damage.

[0043] Then, continue pushing the catheter 3 to insert it into the patient's nasal cavity. At the same time, the movement of the catheter 3 can drive the fixing sleeve 202 to continue moving, so that its top can pass through the inner wall of the mounting plate 201. The snap-fit ​​grooves 409 on the inner side of the four expansion plates 408 can limit the outer side of the top of the fixing sleeve 202, while the clamping clamp 204 can limit the bottom of the fixing sleeve 202. Thus, the fixing sleeve 202 can remain stable on the inner wall of the mounting plate 201, and the catheter 3 can remain stable inside the patient's nasal cavity. This allows medical staff to easily insert the catheter into the patient's nasal cavity. This embodiment specifically solves the problem of inconvenient cleaning of the vibrating screen in the prior art.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
