Description

Technical Field

[0001] This utility model belongs to the field of artificial nose technology, specifically relating to a split-type artificial nose. Background Technology

[0002] A tracheostomy tube is a medical device inserted into a patient's trachea and / or bronchi to create a temporary artificial breathing channel, especially for patients unable to breathe independently. However, due to the presence of pathogenic bacteria and viruses in the air, and the various requirements of the human airway for suitable gases, an artificial nose, also known as a heat and moisture exchange filter, is often installed on the tracheostomy tube. This is a device connected to the outer end of the tracheostomy tube to supply humidified gas to the body. Currently, most artificial noses used clinically are one-piece structures with a disposable filter core inside. Because the artificial nose cannot be disassembled, it must be replaced entirely when it becomes dirty, increasing the cost of use. Utility Model Content

[0003] (1) Technical problems to be solved In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a split artificial nose. This artificial nose aims to solve the problem that the existing artificial noses are all one-piece structures, which cannot be disassembled and need to be replaced as a whole when they get dirty, thus increasing the cost of use.

[0004] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a split-type artificial nose, which includes a filter pipe and a filter core installed inside the filter pipe. The bottom end of the filter pipe is detachably connected to a connector tube. An oxygen inhalation tube, a humidification tube, and a nebulizing tube are installed on the outer surface of the connector tube. The top end of the filter pipe is detachably connected to a venting cover. The upper surface of the venting cover has multiple fan-shaped vent holes. A knob is rotatably connected to the middle of the venting cover. The bottom end of the knob is located inside the venting cover and is fixedly connected to a fan-shaped plate corresponding to the fan-shaped vent holes.

[0005] Preferably, it also includes a dust cover, which is detachably installed on the top of the connector tube, and gauze is installed in the middle of the dust cover.

[0006] Preferably, the bottom end of the filter pipe is fixedly connected to a first threaded post, the connector pipe has a T-shaped structure, and the upper surface of the connector pipe is provided with a first threaded groove corresponding to the first threaded post.

[0007] Furthermore, the filter core is a disposable core, and the bottom end of the filter core contacts the top end of the first threaded post.

[0012] (3) Beneficial effects

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention divides the artificial nose into three detachable parts: an upper structure, a middle structure, and a lower structure. The upper structure allows control of the size of the fan-shaped air vents for better breathing control. The filter element of the middle structure must not be wetted, while nebulization will wet the filter element. The middle structure is designed to be detachable. When the patient is nebulizing, removing the middle structure prevents the filter element from becoming wet. After removing the middle structure, the upper and lower structures are connected, and the nebulizer tube is connected to the nebulizer to achieve the nebulization function. This eliminates the need for family members to hold the nebulizer for the patient, and ensures airway patency and safety. Furthermore, when the filter element of the middle structure becomes dirty, only the middle structure needs to be replaced, without replacing the entire artificial nose, thus reducing usage costs.

[0014] This utility model, by setting an independent dust cover, allows the upper and middle parts of the structure to be removed, and the dust cover with gauze can be placed on the lower part of the structure. The nebulizer tube can then be connected to the nebulizer to achieve the nebulization function. This eliminates the need for family members to hold the nebulizer for the patient, and ensures that the airway is clear and safe. In addition, the dust cover with gauze can block dust and prevent it from falling into the patient's airway. Attached Figure Description

[0022] This specific embodiment is a split-type artificial nose, the structural diagram of which is shown below. Figures 1-6 As shown, the artificial nose includes a filter pipe 1 and a filter core 2 installed inside the filter pipe 1. The filter core 2 is a disposable filter structure with humidification function. The bottom end of the filter pipe 1 is detachably connected to a connector pipe 3. An oxygen inhalation tube 4, a humidification tube 5, and a nebulizing tube 6 are installed on the outer surface of the connector pipe 3. The top end of the filter pipe 1 is detachably connected to a ventilation cover 7. The upper surface of the ventilation cover 7 has multiple fan-shaped ventilation holes 701. A knob 702 is rotatably connected to the middle of the ventilation cover 7. The bottom end of the knob 702 is located inside the ventilation cover 7 and is fixedly connected to a fan-shaped plate 703 corresponding to the fan-shaped ventilation holes 701. By rotating the knob 702, the fan-shaped plate 703 is driven to fully open the fan-shaped ventilation holes 701 on the ventilation cover 7. By rotating the knob 702 in the opposite direction, the fan-shaped plate 703 is driven to partially close the fan-shaped ventilation holes 701 on the ventilation cover 7, thereby better controlling breathing.

[0023] like Figure 1 and Figure 6 As shown: In this embodiment, a dust cover 8 is also included. The dust cover 8 is detachably installed on the top of the connector tube 3. Gauze 9 is installed in the middle of the dust cover 8. A rubber sleeve is fixedly connected to the bottom of the dust cover 8. The upper surfaces of the vent cover 7 and the connector tube 3 are the same size and are both made of plastic. The rubber sleeve at the bottom of the dust cover 8 can be directly fitted onto the outer surface of the connector tube 3 for fixation.

[0024] like Figures 1-4As shown: In this embodiment, the bottom end of the filter pipe 1 is fixedly connected to a first threaded post 101, the connector pipe 3 has a T-shaped structure, and the upper surface of the connector pipe 3 is provided with a first threaded groove 102 corresponding to the first threaded post 101; in this way, the filter pipe 1 and the connector pipe 3 can be fixed together by the first threaded post 101 and the first threaded groove 102, which makes disassembly and installation very convenient.

[0025] like Figure 2 and Figure 4 As shown: In this embodiment, the filter core 2 is a disposable core, and the bottom end of the filter core 2 is in contact with the top end of the first threaded post 101; the filter core 2 can absorb the moisture and heat exhaled by the patient. When the gas inhaled by the patient passes through the filter core 2, the inhaled gas can carry the moisture and heat exhaled by the patient absorbed by the filter core 2 back to the patient's airway.

[0026] like Figure 1 As shown: In this embodiment, the ends of the oxygen inhalation tube 4, humidification tube 5, and nebulization tube 6 away from the connector tube 3 are all integrally fitted with caps 13; this allows the artificial nose to be connected to more devices through the oxygen inhalation tube 4, humidification tube 5, and nebulization tube 6, increasing the convenience of use. When not in use, the caps 13 can block the oxygen inhalation tube 4, humidification tube 5, and nebulization tube 6.

[0027] like Figure 4 and Figure 6 As shown: In this embodiment, a second threaded groove 103 is provided on the upper surface of the filter pipe 1. The first threaded groove 102 and the second threaded groove 103 are the same size. A second threaded post 104 corresponding to the second threaded groove 103 is fixedly connected to the bottom end of the vent cover 7. In this way, the filter pipe 1 and the vent cover 7 can be fixed together by the cooperation of the second threaded groove 103 and the second threaded post 104, which makes disassembly and installation very convenient. In addition, since the first threaded groove 102 and the second threaded groove 103 are the same size, the middle part of the structure can be removed and the upper part of the structure can be connected to the lower part of the structure for better atomization.

[0028] like Figure 4 and 5 As shown: In this embodiment, a first through hole 704 is provided in the middle of the knob 702. A large sealing cover 705 is installed inside the first through hole 704. A second through hole 706 is provided in the middle of the large sealing cover 705. A small sealing cover 707 is installed inside the second through hole 706. Both the large sealing cover 705 and the small sealing cover 707 include a cover plate and a rubber post fixedly connected to the cover plate. In this way, when in use, the rubber post on the large sealing cover 705 and the small sealing cover 707 can be inserted into the first through hole 704 and the second through hole 706. If there is a lot of sputum, the large sealing cover 705 can be opened to insert the suction tube to suction the sputum. If there is a little sputum, the small sealing cover 707 can be opened to insert the suction tube to suction the sputum.

[0029] Working principle: The artificial nose is divided into three detachable and connectable parts. The upper part includes an air vent cover 7, the middle part includes a filter tube 1 and a filter core 2, and the lower part includes a connector tube 3 and an oxygen inhalation tube 4, a humidification tube 5, and a nebulizer tube 6 installed on the outer surface of the connector tube 3. The upper part can be connected to the middle part or the lower part without interference. It also includes a separate dust cover 8 that can be connected to the lower part. Gauze 9 is installed in the middle of the dust cover 8 to prevent dust accumulation.

[0030] In use, the artificial nose is placed over the tracheostomy tube. Specifically, the lower end of the artificial nose connector tube 3 is connected to the tracheostomy tube, the lower end of the filter tube 1 is connected to the upper end of the connector tube 3, and the lower end of the ventilation cover 7 is connected to the upper end of the filter tube 1. By rotating the knob 702, the fan-shaped plate 703 is driven to fully open the fan-shaped ventilation hole 701 on the ventilation cover 7, or the knob 702 is rotated in the opposite direction to drive the fan-shaped plate 703 to partially close the fan-shaped ventilation hole 701 on the ventilation cover 7, thereby better controlling breathing.

[0031] When administering nebulization to a patient, since the filter element 2 cannot be wetted, but nebulization will wet it, the upper structure (ventilation cover 7) and the middle structure (filter pipe 1) along with the filter element 2 must be removed simultaneously. The connector pipe 3 remains connected to the tracheal cannula. Then, the second threaded post 104 of the ventilation cover 7 is threaded into the first threaded groove 102 of the connector pipe 3. Alternatively, a dust cover 8 with gauze 9 can be placed over the connector pipe 3. Then, the cap 13 on the nebulizer tube 6 is opened, allowing the nebulizer tube 6 to connect to the nebulizer for nebulization. This eliminates the need for family members to hold the nebulizer and ensures a clear and safe airway. When nebulization is not needed, the cap 13 blocks the nebulizer tube 6, while the dust cover 8 with gauze 9 or the ventilation cover 7 remains connected to the connector pipe 3, which remains connected to the tracheal cannula. The dust cover 8 with gauze 9 prevents dust from entering the patient's airway. Patients can receive oxygen and airway humidification while undergoing nebulization.

[0032] When a patient requires airway humidification (e.g., by dripping humidification solution into the airway using an infusion set (the humidification solution is 0.45% sodium chloride, or 0.45% sodium chloride combined with ambroxol or ambroxol hydrochloride)), the upper structure, i.e., the ventilation cover 7, and the middle structure, i.e., the filter pipe 1 along with the filter core 2, must be removed simultaneously. The connector pipe 3 remains connected to the tracheal cannula, and the second threaded post 104 of the ventilation cover 7 is threadedly connected to the first threaded groove 102 of the connector pipe 3. The infusion set is then connected to the humidification tube 5 via the connecting pipe, allowing for airway humidification of the patient. Oxygen inhalation and nebulization can also be performed simultaneously with airway humidification.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
