Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a postoperative care device for the nasal cavity. Background Technology

[0002] Surgery inside the nasal cavity is extremely common, and most procedures require incisions inside the nasal cavity. For example, septoplasty involves cutting the nasal mucosa and removing the deviated nasal cartilage to correct the septoplasty. However, because the nasal mucosa is very fragile, it is extremely important to ensure that the nasal mucosa is not damaged or infected during postoperative care.

[0003] However, in current techniques, postoperative care for nasal surgery often involves applying pressure to the nasal cavity wall with sterile cotton balls or gauze coated with hemostatic and disinfectant agents to stop bleeding and prevent infection. After achieving postoperative hemostasis, patients are instructed to change the dressing regularly and on time. This relatively simple procedure is used for postoperative care.

[0004] Currently, the simple routine nursing methods using gauze or sterile cotton balls involve applying pressure. However, the rough texture of these materials can cause significant discomfort to patients, increasing their pain after the anesthesia wears off. Furthermore, the rough surface of gauze or sterile cotton balls makes them prone to secondary tearing of the delicate nasal mucosa surgical wound during removal and replacement, resulting in secondary damage to the nasal cavity. Additionally, nasal surgery sometimes requires simultaneous closure of both nasal cavities, which can easily force patients to breathe only through their mouths, leading to breathing difficulties. During postoperative recovery, patients may unconsciously use their breath to push against the nasal packing, causing nasal cavity expansion and potentially tearing the surgical wound. Summary of the Invention

[0005] In view of this, the purpose of this invention is to propose a postoperative nasal cavity care device to solve the problems in the prior art that there is no care device that can simultaneously achieve flexible and comfortable pressure for hemostasis and dressing change and automated nasal breathing assistance, which causes patients to be extremely uncomfortable during postoperative nasal cavity care, and easily tear the wound, leading to secondary injury and infection, as well as the problem of not being able to breathe normally in the nasal cavity, resulting in difficulty breathing.

[0006] This invention is achieved through the following technical solution:

[0007] A postoperative nasal cavity care device includes a silicone nasal plug tube with a fluid flow hole on its side wall. A metering filter airflow valve is fixedly installed at both ends of the silicone nasal plug tube. A pressing and fixing plate is fixedly installed at the front end of the silicone nasal plug tube. A nasal wing fixing plate is rotatably connected to the left side of the pressing and fixing plate via an elastic clip. A micro-liquid pump is fixedly installed on the surface of the nasal wing fixing plate. The micro-liquid pump is connected to the fluid flow hole via a pipeline. A micro-controller is installed on the surface of the pressing and fixing plate. The micro-controller is connected to the metering filter airflow valve and the micro-liquid pump via wiring.

[0008] Furthermore, an inflatable support sleeve is fixedly installed inside the silicone nasal plug, and a miniature air pump is fixedly installed on the surface of the nasal wing fixing clamp. The miniature air pump is connected to the inflatable support sleeve through a miniature air tube, and the miniature air pump is connected to the miniature controller through a circuit.

[0009] Furthermore, the microcontroller is externally connected to a control panel via a wireless signal.

[0010] Furthermore, the micro liquid pump includes a drug liquid tank and a waste liquid tank. An inlet pipe is fixedly installed at the top of the drug liquid tank, and an outlet pipe is fixedly installed at the bottom of the drug liquid tank. A suction pipe is fixedly installed at the top of the waste liquid tank, and a discharge pipe is fixedly installed at the bottom of the waste liquid tank. The outlet pipe and the suction pipe are both connected to the liquid pump, and the outlet pipe and the suction pipe are both connected to the liquid flow hole through pipelines.

[0011] Furthermore, both ends of the silicone nose plug tube are rounded.

[0012] Furthermore, the fluid flow holes are evenly distributed on the side wall of the silicone nose plug and open outwards.

[0013] Furthermore, a flexible pad is fixedly provided on the inner side of the nose wing fixing clamp.

[0014] Furthermore, the microcontroller is externally connected to a respiratory rate sensor via a wireless signal.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention provides a nursing device that simultaneously achieves flexible and comfortable pressure for hemostasis and dressing changes, as well as automated nasal breathing assistance. By combining a silicone nasal plug with an inflatable support sleeve, it facilitates flexible and comfortable pressure for hemostasis and dressing changes, thereby greatly reducing patient discomfort during postoperative nasal care. Furthermore, the smooth and soft silicone avoids the problem of tearing the wound and causing secondary injury and infection due to pulling. The combination of a respiratory rate sensor and a quantitative airflow valve helps maintain unobstructed breathing after surgery by using the device to match the patient's own breathing rhythm.

[0028] In the above description of the present invention, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is conventionally placed during use. These terms are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0030] like Figure 1-6 As shown, one embodiment of the present invention provides a postoperative nasal cavity care device, including a silicone nasal plug 1. Fluid flow holes 2 are formed on the side wall of the silicone nasal plug, evenly distributed on the side wall and opening outwards. The fluid flow holes do not penetrate the side wall of the silicone nasal plug. The bottoms of all fluid flow holes are connected by pipes. An inflation support sleeve 3 is fixedly installed inside the silicone nasal plug. A metering filter airflow valve 4 is fixedly installed at both ends of the silicone nasal plug. A pressing and fixing plate 5 is fixedly installed at the front end of the silicone nasal plug. A nasal wing fixing clamp 7 is rotatably connected to the left side of the pressing and fixing plate via an elastic clamp 6. A miniature liquid pump 8 is fixedly installed on the surface of the wing fixing clamp. The miniature liquid pump is connected to a liquid flow hole via a pipe. The miniature liquid pump includes a medicine tank 9 and a waste liquid tank 10. An inlet pipe 11 is fixedly installed at the top of the medicine tank, and an outlet pipe 12 is fixedly installed at the bottom of the medicine tank. A suction pipe 13 is fixedly installed at the top of the waste liquid tank, and a drain pipe 14 is fixedly installed at the bottom of the waste liquid tank. Both the outlet pipe and the suction pipe are connected to a liquid pump 15. Both the outlet pipe and the suction pipe are connected to a liquid flow hole via a pipe. A micro controller 16 is installed on the surface of the pressing fixing plate. The micro controller is connected to the miniature liquid pump via a circuit and a quantitative filter airflow valve. A miniature air pump 17 is also fixedly installed on the surface of the nasal wing fixing clamp. The miniature air pump is connected to an inflatable support sleeve via a miniature air tube. The miniature air pump is connected to the micro controller via a circuit. The micro controller is externally connected to a control panel 18 via a wireless signal, and a respiratory rate sensor 19 is externally connected to the micro controller via a wireless signal to sense the human respiratory rate.

[0031] In this embodiment, the soft silicone nasal plug is first inserted into the nasal cavity after initial hemostasis. Insertion is stopped when the inner side of the fixation plate is pressed against the nasal opening. Then, an inflation command is input through the control panel and transmitted to the micro controller. The micro controller then controls the micro air pump to inflate the inflatable support sleeve. When the nasal cavity is observed to be slightly swollen, an instruction is input to stop inflation. The inflatable support sleeve presses the silicone nasal plug against the inner wall of the nasal cavity to stop hemostasis. Then, the nasal wing fixation splint is rotated to clamp the nasal wing, completing the fixation.

[0032] When disinfection and dressing changes are needed, a disinfection command is input through the control panel and transmitted to the micro controller. The micro controller then controls the micro liquid pump to pump the disinfectant and hemostatic solution in the medicine tank through the outlet tube to the liquid flow hole, allowing it to seep out from the liquid flow hole and contact the inner wall of the nasal cavity for disinfection and hemostasis. After a period of soaking, a drainage command is input through the control panel and transmitted to the micro controller. The micro controller then controls the micro liquid pump to generate suction in the suction tube on the waste liquid tank to draw the waste liquid in the liquid flow hole back into the waste liquid tank, completing the drying and cleaning process.

[0033] After the device is assembled, the synchronous assisted breathing command is input through the control panel and transmitted to the microcontroller. The microcontroller then controls the quantitative airflow valve according to the respiratory rate signal transmitted from the respiratory rate sensor, so that it performs synchronous inhalation and exhalation according to the detected respiratory rate, thereby assisting the nasal cavity to perform normal breathing and ensuring unobstructed breathing.

[0034] This embodiment features a nursing device that simultaneously provides flexible and comfortable pressure for hemostasis and dressing changes, as well as automated nasal breathing assistance. The combination of a silicone nasal plug and an inflatable support sleeve facilitates flexible and comfortable pressure for hemostasis and dressing changes, significantly reducing patient discomfort during postoperative nasal care. Furthermore, the smooth and soft silicone prevents tearing of the wound during pulling, thus avoiding secondary injury and infection. The combination of a respiratory rate sensor and a quantitative airflow valve helps maintain unobstructed breathing after surgery by adapting the device to the patient's own breathing rhythm.

[0035] In this embodiment, both ends of the silicone nasal plug are rounded. Rounding the corners helps prevent the sharp edges from scratching the nasal cavity after the silicone nasal plug is inserted, and the rounded silicone nasal plug is easier to insert into the nasal cavity smoothly.

[0036] In this embodiment, a flexible pad is fixedly provided on the inner side of the nasal wing fixation splint. The flexible pad helps to avoid strong discomfort in the nasal wing during long-term clamping of the nasal wing fixation splint.

[0037] In this embodiment, the device shown is for use in the left nostril. After nasal surgery has been performed in both nostrils, the device can be rotated to be used in the right nostril. The device has a wire connector 20 fixedly installed on the right side of the pressing and fixing plate. When the device is needed in the right nostril, the wire connectors on both sides are aligned after rotating the device 180° clockwise. The two wire connectors can then be connected to achieve linkage between the two devices, thereby enabling simultaneous device wearing control in both nostrils.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
