Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an artificial nose. Background Art

[0002] Tracheotomy is a surgery that makes a horizontal incision between the tracheal cartilages of a patient to establish an artificial airway. Currently, an artificial nose is usually connected to the patient's airway. The artificial nose is provided with a humidifying material that can humidify dry air to provide humid air. For existing artificial noses, when there is a large amount of secretion in the patient's airway, if the patient coughs violently, the sputum in the airway is likely to be sprayed onto the humidifying material, resulting in blockage of the humidifying material and causing the patient to suffocate. In response to this situation, the current common practice is to increase the frequency of checking the artificial nose. When it is found that the artificial nose is blocked, the artificial nose is immediately replaced. However, this approach increases the workload of medical staff; in addition, due to the relatively frequent replacement of the artificial nose, it also increases the economic burden on the patient. Summary of the Utility Model

Inside the upper housing 100, there is a perforated partition 110 and a detachable support plate 120. The perforated partition 110 is located above the support plate 120. A humidification and filtration chamber 130 is defined between the perforated partition 110 and the support plate 120. A humidification material 131 is provided in the humidification and filtration chamber 130. The upper housing 100 further has a pipe 140. An oxygen chamber 150 is defined between the perforated partition 110 and the top wall of the upper housing 100. The perforated partition 110 is provided with a plurality of tiny through holes, and the through holes on the perforated partition 110 communicate the humidification and filtration chamber 130 with the oxygen chamber 150. A first opening 141 communicating with the oxygen chamber 150 is provided on the side wall of the pipe 140, and a second opening 142 is provided at the lower end of the pipe 140. An oxygen inlet 160 communicating with the humidification and filtration chamber 130 is provided on the side wall of the upper housing 100. The lower housing 200 has a sputum storage chamber 210. The lower housing 200 is detachably connected to the upper housing 100. The sputum storage chamber 210 of the lower housing 200 is located below the humidification and filtration chamber 130. The support plate 120 is used to isolate the sputum storage chamber 210 from the humidification and filtration chamber 130. A sputum discharge port 220 communicating with the sputum storage chamber 210 is provided on the bottom wall of the lower housing 200. The ventilation pipe 300 passes through the bottom of the lower housing 200 and is connected to the sputum storage chamber 210 and the second opening 142. A first diversion wall 310 is provided at the edge of the upper end of the ventilation pipe 300. The first diversion wall 310 extends downward and is inclined. The position of the end of the first diversion wall 310 away from the ventilation pipe 300 is lower than the position of the end of the first diversion wall 310 close to the ventilation pipe 300. A sputum storage chamber 210 is defined between the first diversion wall 310 and the bottom wall of the lower housing 200. The ventilation pipe 300 is located below the second opening 142. A second diversion wall 143 is provided at the edge of the second opening 142. The second diversion wall 143 extends downward and is inclined. The position of the end of the second diversion wall 143 away from the pipe 140 is lower than the position of the end of the second diversion wall 143 close to the pipe 140. The second diversion wall 143 is located above the first diversion wall 310.

[0026] Referring to Figure 1 the arrow direction in Figure 1The direction of the arrow in the figure is the direction of air flow. The lower end of the ventilation tube 300 is connected to the patient's airway, and the oxygen supply port 160 is connected to the oxygen supply device. The oxygen supply device can provide oxygen-rich fresh air. When the patient inhales, the external air enters the upper shell 100 from the oxygen supply port 160. The external air is first humidified by the humidification material 131, and then enters the oxygen chamber 150 through the through hole of the perforated partition 110. The oxygen chamber 150 can facilitate air flow, and then the humidified air enters the pipe 140 through the first opening 141 of the pipe 140, and then flows out from the second opening 142 of the pipe 140, and enters the ventilation tube 300, and then is delivered to the patient's airway. Figure 2 The direction of the arrow in Figure 2 The direction of the arrow in the figure is the direction of sputum flow. When the patient coughs, the sputum in the patient's airway sprays upward into the ventilation tube 300, and the sputum is blocked by the second guide wall 143. At the same time, the sputum adheres to the second guide wall 143 and slides along the second guide wall 143, and drips to the first guide wall 310. The first guide wall 310 can guide the sputum into the sputum storage cavity 210, and the sputum will accumulate on the bottom wall of the lower shell 200. Since the first guide wall 310 is inclined, the first guide wall 310 blocks the sputum in the sputum storage cavity 210. When the artificial nose 1000 is slightly tilted, the sputum is not easy to flow back into the ventilation tube 300. The sputum discharge port 220 of the lower shell 200 can be connected to a sputum suction device to automatically suck away the sputum in the sputum storage cavity 210. In addition, since the support plate 120 blocks the sputum, the sputum will not come into contact with the humidifying material 131, thereby ensuring that the humidifying material 131 is not blocked by the sputum and there is no need to replace the artificial nose multiple times.

[0027] It should also be noted that since the pipe 140 is long and the inner diameter of the pipe 140 is smaller than the inner diameter of the ventilation tube 300, it is not easy for sputum to reach the upper end of the pipe 140, and the sputum will be blocked by the second guide wall 143. If the sputum reaches the inner wall of the pipe 140, the sputum will flow along the inner wall of the pipe 140 to the second guide wall 143, and then flow along the second guide wall 143 to the first guide wall 310.

[0028] It should be noted that, refer to Figure 3 As shown, the upper shell 100 and the lower shell 200 can be disassembled, and the support plate 120 of the upper shell 100 can be disassembled to replace the humidifying material 131 in the humidifying filter cavity 130, and the sputum in the lower shell 200 can be poured out and the lower shell 200 can be cleaned.

[0029] Reference Figure 5As shown, in some embodiments, the support plate 120 is connected to the upper housing 100 through a snap structure. The support plate 120 includes a first plate 121 and a second plate 122. The first plate 121 and the second plate 122 are semi-circular. An avoidance hole 123 for avoiding the pipeline 140 is formed between the first plate 121 and the second plate 122. Refer to Figure 4 As shown, when replacing the humidifying material 131, first invert the upper housing 100, first place the humidifying material 131 on the perforated partition 110, and then cover the first plate 121 and the second plate 122. The first plate 121 and the second plate 122 can press the humidifying material 131 tightly.

[0030] Refer to Figure 2 As shown, in some embodiments, the second diversion wall 143 is parallel to the first diversion wall 310. The length of the first diversion wall 310 is greater than the length of the second diversion wall 143, which is beneficial for sputum to flow along the first diversion wall 310 and the second diversion wall 143 into the sputum storage cavity 210.

[0031] In some embodiments, the humidifying material 131 has an annular structure, the perforated partition 110 is circular, and the pipeline 140 passes through the middle of the perforated partition 110.

[0032] Refer to Figure 1 As shown, in some embodiments, the first diversion wall 310 extends along the circumferential direction of the ventilation pipe 300, the second diversion wall 143 extends along the circumferential direction of the pipeline 140, and the first diversion wall 310 and the second diversion wall 143 have a generally conical structure.

[0033] Refer to Figure 1 As shown, in some embodiments, the upper end of the pipeline 140 penetrates outside the upper housing 100. A detachable end cap 144 is provided at the upper end of the pipeline 140. The end cap 144 can be periodically removed or kept open so that the carbon dioxide exhaled by the patient is discharged from the upper end of the pipeline 140. The upper end of the pipeline 140 can also be connected to a carbon dioxide detector, and the carbon dioxide detector can detect the carbon dioxide concentration exhaled by the patient.

[0034] Refer to Figure 4 As shown, in some embodiments, the upper housing 100 is provided with a guiding portion 170. The guiding portion 170 has an annular structure, and the guiding portion 170 can guide the pipeline 140 to be inserted into the guiding portion 170.
