Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to an artificial nose for preventing sputum splashing. Background Art

[0002] An artificial nose is also used as a heat and moisture exchanger filter, which can simulate the function of the nose, collect and retain the heat and water vapor in the exhaled air to warm and humidify the inhaled gas, and simulate the environment of nasal inhaled air for patients.

[0003] In the prior art, such as the publication number: CN218129515U, a disclosed multifunctional artificial nose includes an artificial nose, in which a heat and moisture exchange filter is installed at the inner front end. A bracket is vertically and fixedly arranged in the middle of the artificial nose. The bracket includes an outer frame and a through-hole frame arranged at the center of the outer frame. A solid partition is arranged at the bottom side of the through-hole frame. A slot is opened at the top end of the solid partition. The bottom end of the diaphragm frame is inserted into the slot, and the top end passes through the through-hole. A sputum storage chamber is arranged at the inner rear end of the artificial nose. The middle part of the sputum storage chamber is communicated with a tracheal catheter connecting pipe. The bottom of the sputum storage chamber is communicated with the outside through a sputum discharge hole arranged on the outer wall of the artificial nose. On the basis of the traditional artificial nose, this multifunctional artificial nose adds a replaceable filter paper and a sputum storage cavity design for sputum discharge, thereby increasing the filtering effect of the artificial nose, facilitating the collection and discharge of sputum, effectively preventing environmental pollution caused by coughing sputum splashing, protecting the heat and moisture exchange filter, and greatly reducing the replacement frequency of the artificial nose.

[0004] However, this device still has some problems. Among them, by providing a sputum storage chamber, the middle part of the sputum storage chamber is communicated with the tracheal catheter connecting pipe, and the bottom of the sputum storage chamber is communicated with the outside through a sputum discharge hole arranged on the outer wall of the artificial nose, which is beneficial to the collection and discharge of sputum. However, during use, after the sputum enters the sputum storage chamber, it accumulates in the sputum storage chamber. If there is a large amount of sputum, it may cause the sputum to flow back into the tracheal catheter connecting pipe, thereby causing discomfort to the patient during use. Therefore, we disclose an artificial nose for preventing sputum splashing to meet people's needs. Summary of the Utility Model

[0023] Reference Figure 1 and 2 the shown Embodiment 1

[0024] An artificial nose for preventing sputum splashing includes an artificial nose body 1. An installation opening is provided on one side of the artificial nose body 1, and a tracheal connection tube 2 is fixedly installed in the installation opening. An anti-splashing tube 3 is fixedly installed on the inner wall of the artificial nose body 1. One end of the anti-splashing tube 3 is fixedly installed with an air exchange tube 4. A ventilation opening is provided on the other side of the artificial nose body 1, and the other end of the air exchange tube 4 is installed in the ventilation opening. A movable plate 5 is rotatably installed on the inner wall of the anti-splashing tube 3. A diversion opening is provided on the lower side of the anti-splashing tube 3, and a liquid guide tube 6 is fixedly installed in the diversion opening. A check valve 7 is installed at the bottom end of the liquid guide tube 6. A suction outlet is provided on the lower side of the artificial nose. The air exchange tube 4 is in a trumpet shape and fits with the ventilation opening. The movable plate 5 installed inside the anti-splashing tube 3 can be turned up and down, which will not affect the patient's breathing. When sputum splashes out from the tracheal connection tube 2, it can effectively block the sputum and prevent the sputum from flowing into the air exchange tube 4.

[0025] As Figure 1 and 2 shown, an outer connection tube 8 is fixedly installed in the suction outlet. The bottom end of the outer connection tube 8 is screwed with a cover 9. An observation opening is provided on the lower side of the cover 9, and an observation plate 10 is installed in the observation opening. The observation plate 10 is installed in a ring shape on the cover 9. The observation plate 10 is made of transparent glass. During the patient's use, the artificial nose body 1 can be appropriately turned over, and the collection state of the internal sputum can be observed through the observation plate 10.

[0026] During use, connect the patient's breathing tube to the tracheal connection tube 2 to use. When the patient breathes through the tracheal connection tube 2, if there is sputum overflow, it can enter the anti-splashing tube 3 through the tracheal connection tube 2. The movable plate 5 in the anti-splashing tube 3 intercepts it appropriately to prevent the sputum from entering the air exchange tube 4, and the sputum is diverted to the sputum collection cavity in the artificial nose body 1 through the liquid guide tube 6, and the check valve 7 prevents the sputum from flowing back, so as to better collect the sputum and prevent it from flowing back. When it is necessary to collect the sputum, the cover 9 can be unscrewed and the outer connection tube 8 can be connected for sputum suction operation.

[0027] Embodiment 2 is a further optimization based on Embodiment 1:

[0028] As Figure 4 shown, on one side of the artificial nose body 1, a mounting plate 11 is fixedly installed. On one side of the mounting plate 11, two mounting grooves are provided. In both of the two mounting grooves, a connecting plate 16 is arranged. On one side of the two connecting plates 16, the same humid-heat exchange filter 15 is fixedly installed. The humid-heat exchange filter 15 is consistent with the technology used in the above-cited document.

[0029] As Figure 4 shown, on both sides of the mounting plate 11, fixing openings are provided. In the fixing openings, mounting pipes 17 are fixedly installed. On one side of the mounting pipes 17, sliding holes are provided. In the sliding holes, pull rods 19 are slidably installed. On one side of the connecting plate 16, fixing holes are provided.

One end of the mounting pipe 17 is fixedly installed with a sealing plate 21. The pull rod 19 is slidably installed on the sealing plate 21. Pull the pull rod 19 outwards to completely contract the pull rod 19 into the mounting pipe 17. Then, insert the connecting plate 16 into the fixing opening and align the fixing hole with the sliding hole. Then, release the pull rod 19. The reaction force of the spring 20 drives the pull rod 19 to reset and insert into the fixing hole, thus achieving the effect of quickly disassembling and replacing the humid-heat exchange filter 15.

[0031] As Figure 3 shown, on the upper side of the mounting plate 11, a placing groove is provided. In the placing groove, a filter plate 12 is slidably installed. The filter plate 12 is in contact with the air exchange pipe 4 to isolate the inhaled and exhaled gases.

[0032] As Figure 3 shown, on the upper side of the filter plate 12, an avoidance hole is provided. On the upper side of the mounting plate 11, two clamping grooves are provided. In the two clamping grooves, adsorption grooves are provided. The adsorption grooves correspond to the avoidance hole. On the inner bottom wall of the adsorption groove, a magnetic attraction stone 14 is fixedly installed. In the clamping groove, an inserting strip 13 is slidably installed. When the filter plate 12 needs to be replaced, the filter plate 12 can be pulled out of the outside of the placing groove, and a new filter plate 12 can be replaced. Then, insert the inserting strip 13 into the adsorption groove and adsorb it through the magnetic attraction stone 14 to fix the filter plate 12.
