Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to a nursing device for changing dressings after endoscopic nasal surgery in otolaryngology. Background Technology

[0002] Endoscopic sinus surgery has become the primary treatment for chronic sinusitis and nasal polyps. Dressing changes during endoscopic surgery are crucial, not only reducing postoperative complications but also significantly improving surgical success and cure rates. The routine dressing change involves spraying a mixture of 1% ephedrine and 1% tetracaine topical anesthetic into the nasal cavity, followed by a thorough endoscopic examination to remove blood clots, dried secretions, and crusts from the nasal and sinus cavities. Finally, the sinuses and nasal cavity are rinsed with saline solution, and suction is used to remove any remaining contents, ensuring a clean surgical environment conducive to mucosal recovery. In summary, the inventors have found that existing nursing devices for post-endoscopic nasal dressing changes have the following main defects: During the dressing change process, a large amount of rinsing fluid mixed with hemostatic materials, blood, nasal secretions, and other contaminants is flushed out of the patient's mouth and nose. This is discharged into the trash can using only a relatively simple drainage tube. However, during this process, the patient may inadvertently shake or sneeze due to discomfort, generating a reverse recoil force. This causes the contaminants inside the drainage tube to shake and splash reflexively, resulting in an uneven discharge process. In some cases, blockages and residue buildup may occur inside the drainage tube, affecting the progress of the dressing change and the nursing effect of the device on post-endoscopic nasal dressing changes in otolaryngology. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical objective is: a nursing device for dressing change after endoscopic nasal surgery in otolaryngology, the structure of which includes: a supporting nursing structure, a movable base, a fixing ring, a support rod, a lighting plate, a hinged arm, and a collection groove. The supporting nursing structure is set outside the support rod through the fixing ring and the hinged arm, and a collection groove is installed in the middle of the supporting nursing structure. The movable base is provided with a support rod and a lighting plate and is electrically connected.

[0004] As a further improvement of the present invention, the supporting care structure is provided with a positioning buckle, which is installed on the outside of the outer wrapping strip and the inside of the outer wrapping strip is also provided with a collection groove through the tray to cooperate with the limiting structure from top to bottom. The outside of the tray is connected with an adhesive strip and the outside of the tray plate.

[0005] As a further improvement of the present invention, the positioning buckle is also provided with a handle, the handle and the anti-detachment block are fixed to one end of the clip, and the other end of the clip is installed on the outside of the block by a buckle.

[0006] As a further improvement of the present invention, a tray is fitted inside the outer wrapping strip of the support care structure. The tray then uses a limiting structure to position the collection slot at the center of gravity of the tray, and the tray can adjust the diameter and height of the conical bottom of the tray by using the positioning buckle, the handle and the anti-detachment block to pull the clip to slide left and right at a fixed point inside the buckle to change the length of the clip.

[0007] As a further improvement of the present invention, the external support and care structure is perpendicular to the support rod via a hinged arm and a fixing ring. The lighting plate and the movable base of the support rod contain an electric structure and a remote wireless information transmission structure. The bottom of the movable base is engaged with the ground to complete the height positioning, and the center of gravity of the support and care structure is perpendicular to the center of the collection tank.

[0008] As a further improvement of the present invention, the positioning buckle is disposed outside the outer wrapping strip and the middle of the outer wrapping strip is provided with a limiting structure and a tray to place the collection groove in the outer wrapping strip, while the adhesive strip has two strips to allow the tray to be inclinedly embedded in the outer edge of the tray's conical structure.

[0009] As a further improvement of the present invention, the handle and the anti-detachment block are matched with the buckle at one end of the clip strip. The inner side of the clip strip is provided with a number of soft tooth-like structures arranged at equal intervals, which are matched with the hollow internal structure of the buckle and fixedly connected to the outside of the block. The buckle and the block are arranged in parallel at the end of the rubber strip.

[0010] As a further improvement of the present invention, the limiting structure is also provided with a connecting rod, which is installed on the edge of the buckle plate and the guide groove. One end of the guide groove is fixedly connected to the middle of the collection groove, and the buckle plate and the control cover are fixed on the upper surface of the collection groove.

[0011] As a further improvement of the present invention, the cross-section of the collection groove is an arc-shaped crescent structure, which is embedded in the middle of the tray and the collection groove is set inside the collection groove by a buckle plate.

[0012] As a further improvement of the present invention, the connecting rod is also provided with a sleeve, and a support rod is sleeved in the middle of the sleeve and a swing blade is installed thereon.

[0013] As a further improvement of the present invention, the sleeve and the support rod are vertically installed at the ends of the buckle plate and the guide groove, and the sleeve completes the positioning and linear descent of the support rod inside the collection groove through the external swing blade, and the lower edge of the swing blade slides and engages with the inclined surface of the buckle plate.

[0014] As a further improvement of the present invention, the collection trough is provided with a connection interface, and a tray is movably secured to the outside of the connection interface by an adhesive strip. The bottom of the connection interface is fixedly connected to the folding bucket, and a storage bucket is provided under the folding bucket by a collar.

[0015] As a further improvement of the present invention, the inner diameter of the interface matches the outer diameter of the folding bucket, and the inner wall of the folding bucket is provided with pleats that match the spacing of the buckle plate at the lower edge of the collection trough, and the pleat spacing of the folding bucket changes synchronously with the tilt angle of the buckle plate.

[0016] As a further improvement of the present invention, the storage bucket is further provided with round beads, which are equidistantly arranged outside the circular ring, and the circular ring is arranged on the top of the inner cylinder and the outer cylinder.

[0017] As a further improvement of the present invention, the inner tube has vertical stripes inside and the outer tube is vertically installed at the bottom of the folding tube, and is vertically restrained by the center of gravity of the pallet.

[0018] Compared with the prior art, the present invention has the following advantages: 1. This invention further improves the support and care structure by using a positioning buckle to open the tray and adjusting the distance between the tray and the adhesive strip at the edge of the tray according to the radial direction of the patient's chin. This allows the tray and outer wrapping strip to change into a conical shape, and the adhesive strip and tray surround the outside of the patient's chin, so that the patient's chin faces away from the lighting panel. The change in the angle of the tray and the limiting structure can restrict the direction of the patient's oral and nasal contaminant excretion and guide it to better drain into the collection trough, preventing contaminants from being sprayed in all directions.

[0019] 2. With further improvements to the limiting structure, this invention, through the up-and-down control of the connecting rod on the buckle plate and the guide groove, can press the control cover when the guide groove is initially subjected to direct pollutant discharge. This causes the holes on the surface of the control cover to open synchronously, starting unidirectional opening and accelerating the adsorption of sprayed mist pollutants from the air. When there is no sneezing or the internal air pressure of the device is low, the holes on the surface of the control cover will quickly close to prevent the mist pollutants from scattering. At the same time, the connecting rod at the top of the collection tank will shorten downwards under force. Using the lever principle, the guide groove pulls the top of the collection tank closer to the patient's cheek, changing the distance between the device and the patient's cheek and the flow direction of the pollutants, thus better concentrating the pollutants.

[0020] 3. With further improvements to the collection tank, the present invention, by using the tray and buckle plate installed on the outside of the interface to guide pollutants in a directional manner, can drive the folds of the folding bucket to extend downward synchronously, changing the guiding space and smoothness of the pollutants by the folding bucket, and can also drive the storage bucket at the bottom of the folding bucket to shake back and forth synchronously, which can change the direction and even out the pollutants discharged in a directional manner, so that they are better placed in the storage bucket, avoiding direct flow collision between pollutants and splashing.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings: Example 1: Figures 1 to 5 As shown: This invention provides a nursing device for dressing changes after endoscopic nasal surgery in otolaryngology. Its structure includes: a support and care structure 1, a movable base 2, a fixing ring 3, a support rod 4, a lighting panel 5, a hinged arm 6, and a collection trough 7. The support and care structure 1 is set outside the support rod 4 through the fixing ring 3 and the hinged arm 6, and the collection trough 7 is installed in the middle of the support and care structure 1. The support rod 4 and the lighting panel 5 are set on the upper part of the movable base 2 and are electrically connected.

[0031] The supporting care structure 1 is provided with a positioning buckle 11, which is installed on the outside of the outer wrapping strip 15. The outer wrapping strip 15 is also provided with a collection groove 7 through the tray 16, which will cooperate with the limiting structure 14. The outside of the tray 16 is connected to the outer side of the adhesive strip 13 and the outside of the tray 12.

[0032] The positioning buckle 11 is also provided with a handle 111. The handle 111 and the anti-detachment block 112 are fixed to one end of the locking strip 114, and the other end of the locking strip 114 is installed on the outside of the block 115 through the buckle 113. The tray 16 is fitted inside the outer wrapping strip 15 of the support care structure 1. The collection slot 7 is positioned at the center of gravity of the tray 16 by the limiting structure 14. The tray 16 can adjust the diameter and height of the conical bottom by using the positioning buckle 11, the handle 111 and the anti-detachment block 112 to pull the locking strip 114 to slide left and right at a fixed point inside the buckle 113 to change the length of the locking strip 114.

[0033] The supporting care structure 1 is externally perpendicular to the support rod 4 via the hinged arm 6 and the fixing ring 3. The lighting plate 5 of the support rod 4 and the movable base 2 contain an electric structure and a remote wireless information transmission structure. The bottom of the movable base 2 is engaged with the ground to complete the height positioning. The center of gravity of the supporting care structure 1 is perpendicular to the center of the collection tank 7.

[0034] The positioning buckle 11 is located outside the outer wrapping strip 15, and the outer wrapping strip 15 is fitted with a limiting structure 14 and a tray 16 in the middle to allow the collection groove 7 to be placed in the outer wrapping strip 15. The adhesive strip 13 has two strips to allow the tray 12 to be inclinedly embedded in the outer edge of the conical structure of the tray 16.

[0035] The handle 111 and the anti-detachment block 112 are fitted with the buckle 113 at a distance through one end of the clip 114. The inner side of the clip 114 is provided with a number of soft tooth-like structures arranged at equal intervals, which are matched with the hollow internal structure of the buckle 113 and fixedly connected to the outside of the block 115. The buckle 113 and the block 115 are arranged in a parallel orientation at the end of the adhesive strip 13.

[0036] The limiting structure 14 is further provided with a connecting rod 141, which is installed on the edge of the buckle plate 142 and the guide groove 143. One end of the guide groove 143 is fixedly connected to the middle of the collection groove 145. The buckle plate 142 and the control cover 144 are fixed on the upper surface of the collection groove 145.

[0037] The collection groove 145 has a cross-section of an arc-shaped crescent structure, is embedded in the middle of the tray 16, and is set inside the collection groove 7 by a buckle plate 142.

[0038] The connecting rod 141 is also provided with a sleeve 411, and a support rod 412 is sleeved in the middle of the sleeve 411 and a swing blade 413 is installed thereon.

[0039] The sleeve 411 and the support rod 412 are vertically installed at the ends of the buckle plate 142 and the guide groove 143. The sleeve 411 is positioned and descends linearly inside the collection groove 7 by the external swing blade 413. The lower edge of the swing blade 413 is slidably fitted on the inclined surface of the buckle plate 142.

[0040] The specific functions and operation procedures of this embodiment are as follows: In this invention, the nursing device for dressing changes after endoscopic nasal surgery in otolaryngology can be moved to the front of a seated patient via a mobile base 2. The mobile base 2, through its power supply and remote wireless information transmission structure, receives external remote control signals and fixes the entire device to the ground. The lighting panel 5, facing the patient's mouth and nose, is opened via a support rod 4. The support rod 4, through a fixing ring 3 and a hinged arm 6, supports the nursing structure 1, which is vertically positioned at the patient's bottom. Pressing the anti-dislodgement block 112 on the handle 111 causes the locking strip 114 to disengage from the positioning buckle 11 and wrap around the patient's back, positioning the patient's chin between the deformable tray 12 and the adhesive strip 13. The handle 111 then allows the locking strip 114 to re-enter the positioning buckle 11, and, based on the width of the patient's chin, the soft tooth structure on the outer side of the locking strip 114 engages with the positioning buckle 11 in stages. This better reduces the recoil force caused by sneezing during dressing changes and also better pulls the outer wrapping strip 15 and tray 16 into a conical shape, reducing their size. The diameter of the device further controls the patient's chin, placing it between the deformable support plate 12 and the adhesive strip 13. However, when the contaminants from the patient's dressing change flow down through the mouth and nose, the ejected contaminants first flow into the cone-shaped support plate 12 and then flow along its inclined surface towards the center of gravity at the tip of the support plate 12. Moreover, the downward-flowing contaminants are concentrated by the guide groove 143 and the collection groove 145. Under the influence of gravity, the guide groove 143 will simultaneously press the sleeve 411 at the end of the guide groove 143 to coordinate with the swing. 413 is pressed down on the outside of the support rod 412 and the tip of the buckle plate 142, so that the arc-shaped bottom of the guide groove 143 is close to the buckle plate 142 and the control cover 144. This not only presses the buckle plate 142 into the collection tank 7, but also presses open the hole of the control cover 144, making it open in one direction. This will create a negative pressure to absorb the pollutants splashed in the tray 12 into the collection tank 145, preventing the pollutants from polluting the air in a mist, increasing the speed of pollutant collection, and strengthening the nursing capacity of the support nursing structure 1.

[0041] Example 2: Figures 6 to 7 As shown: This invention provides a nursing device for dressing changes after endoscopic nasal surgery in otolaryngology. Its structure includes a collection trough 7 having an interface 71, a tray 16 being movably engaged with the outside of the interface 71 by a rubber strip 13, and the bottom of the interface 71 being fixedly connected to a folding bucket 74, with a storage bucket 73 provided under the folding bucket 74 by a collar 72.

[0042] The inner diameter of the interface 71 matches the outer diameter of the folding barrel 74, and is located at the lower edge of the collection groove 145 with the tray 16. The inner wall of the folding barrel 74 is provided with pleats that match the spacing of the buckle plate 142, and the pleat spacing of the folding barrel 74 changes synchronously with the tilt angle of the buckle plate 142.

[0043] The storage bin 73 is also provided with beads 731, which are equidistantly arranged outside the ring 733, and the ring 733 is arranged on the top of the inner cylinder 732 and the outer cylinder 734.

[0044] The inner tube 732 has vertical stripes inside, and the outer tube 734 is vertically installed at the bottom of the folding tube 74 and is vertically restrained by the center of gravity of the tray 16.

[0045] The specific functions and operation procedures of this embodiment are as follows: In this invention, when pollutants flow and are collected at the interface 71 of the collection tank 7, they are pressed against the inside of the folded bucket 74 at the bottom of the interface 71 by the inclined pressing of the buckle plate 142. The folds of the folded bucket 74 are opened downwards, so that the folded bucket 74 extends downwards layer by layer. Due to the gravity of the pollutants, the inner cylinder 732 and the outer bucket 734 under the bottom ring 72 vibrate. With the help of the round beads 731 outside the ring 733 rolling inside the ring 72, the inner cylinder 732 and the outer bucket 734 are driven to rotate continuously under the ring 72 and the folded bucket 74. Thus, the vertical stripes inside the inner cylinder 732 can comb and drive the directional pollutants to change direction and settle evenly due to the centrifugal force rotation adjustment. It also avoids the collision and splashing of pollutants discharged at different times, thereby ensuring the control of pollutants by the collection tank 7, and improving the patient dressing change process and the nursing effect of the nursing device for dressing changes after endoscopic otolaryngology.

[0046] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solutions described in this invention, or by designing similar technical solutions by those skilled in the art under the inspiration of the technical solutions described in this invention, falls within the protection scope of this invention.
