[0025] The embodiments of the utility model are described in detail below, and examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model, and cannot be understood as a limitation of the utility model.
[0026] The drawings are referred to below Figures 1 to 4 The upper airway patency evaluation device of the embodiment of the utility model is described below.
[0027] As Figures 1 to 4 shown, the upper airway patency evaluation device of the embodiment of the utility model comprises: a tracheostomy cannula 1, an adapter pipe 2, a speech one-way valve 3 and an air pressure detector 4.
[0028] The tracheal cannula 1 comprises a tracheal cannula body 11 and an inner air bag 12 arranged on the outer peripheral wall of the tracheal cannula body 11 and adjacent to one end of the tracheal cannula body 11, the adapter pipe 2 comprises a first port 21, a second port 22 and a third port 23, the first port 21 is in communication with the other end of the tracheal cannula body 11, a one-way voice valve 3 is installed at the second port 22, the one-way voice valve 3 allows air to flow into the tracheal cannula body 11 in one direction only, and a gas pressure detector 4 is in communication with the third port 23, and the gas pressure detector 4 is used to detect the pressure in the adapter pipe 2.
[0029] As shown in Figure 1 The outer air bag 15 is in communication with the inner air bag 12 through the connecting pipe 13, and a syringe can be in communication with the outer air bag 15 to suck the gas in the inner air bag 12.
[0030] It can be understood that when the tracheal cannula 1 is normally implanted, the inner air bag 12 is filled with gas and is in an inflated state, and the inner air bag 12 can be in contact with the tracheal wall of the patient to support the tracheal cannula body 11, thereby improving the stability of the tracheal cannula 1 after implantation. When the patient needs to speak or the medical staff needs to assess whether the upper airway of the patient is unobstructed, the gas in the inner air bag 12 can be discharged, and the one-way voice valve 3 is worn, so that the carbon dioxide generated in the lung can be discharged through the upper airway.
[0031] According to the embodiment of the utility model, when it is necessary to assess whether the upper airway of the patient is unobstructed, the gas in the inner air bag 12 can be extracted, at this time, the patient can inhale external air into the lung by using the one-way voice valve 3, because the one-way voice valve 3 allows gas to flow in one direction only, the air exhaled by the patient is divided into two paths, one path is discharged through the upper airway, and the other path enters the gas pressure detector 4 through the third port 23. When the upper airway of the patient is not unobstructed, the gas discharge will be hindered, and thus the value detected by the gas pressure detector 4 will increase. When the upper airway of the patient is unobstructed, the gas can be normally discharged from the upper airway, and the value detected by the gas pressure detector 4 will be lower. The medical staff can determine whether the upper airway of the patient is unobstructed by the detected value of the gas pressure detector 4, so as to assess whether the patient meets the extubation requirement.
[0032] Therefore, the upper airway unobstructedness assessment device of the embodiment of the utility model can detect and assess the unobstructedness of the upper airway of the patient without the endoscope, which is beneficial to reduce the damage to the patient and has a simple operation step.
[0033] The upper airway unobstructedness assessment device of the embodiment of the utility model can be used for adults and children, and the present application does not limit this.
[0034] In other words, the upper airway patency evaluation device of the embodiment of the present application can detect and evaluate whether the upper airway of the patient is unobstructed in a non-invasive manner, can reduce the probability of damaging the upper airway of the patient, and can reduce the pain of the patient, and the detection and evaluation manner of the upper airway patency evaluation device of the embodiment of the present application is simple, easy to operate, and has good use effect.
[0035] Optionally, as shown in Figures 3 to 4 The tracheostomy cannula 1 and the adapter pipe 2 are detachably connected. It can be understood that the tracheostomy cannula 1 and the adapter pipe 2 are connected in a split type, and when the tracheostomy cannula 1 needs to be connected to a breathing machine or a sputum suction tube or the like, the adapter pipe 2 can be separated from the tracheostomy cannula 1, so as to facilitate the operation of medical staff. In addition, the tracheostomy cannula 1 and the adapter pipe 2 of the embodiment of the present application can be manufactured in a split type, so that the tracheostomy cannula 1 and the adapter pipe 2 are produced by using different materials.
[0036] For example, the tracheostomy cannula 1 is a soft pipe material and has a certain flexibility and elasticity, so as to reduce the damage to the airway of the patient. Since the adapter pipe 2 is located outside the patient's body, the adapter pipe 2 can be manufactured by using a relatively hard material.
[0037] In an example, as shown in Figure 4 The other end of the tracheostomy cannula body 11 has a plug-in section 111, the plug-in section 111 is plugged with the first port 21, and the plug-in section 111 is rotatable relative to the tracheostomy cannula body 11. It can be understood that the tracheostomy cannula body 11 and the adapter pipe 2 are connected in a plug-in manner, which can facilitate the medical staff to install and dismount the adapter pipe 2. In addition, since the plug-in section 111 can rotate relative to the tracheostomy cannula body 11, the medical staff can rotate the adapter pipe 2 to a suitable angle according to actual needs, so as to connect the adapter pipe 2 with the air pressure detector 4.
[0038] Optionally, as shown in Figure 4 The adapter pipe 2 comprises an inner pipe 241 and an outer pipe 242, the inner pipe 241 is coaxially sleeved in the outer pipe 242, the outer pipe 242 is spaced apart from the inner pipe 241 along the radial direction of the inner pipe 241, and the plug-in section 111 can be inserted into the inner pipe 241. Alternatively, the plug-in section 111 can be inserted between the inner pipe 241 and the outer pipe 242. Alternatively, the plug-in section 111 is sleeved on the outside of the outer pipe 242. It can be understood that the adapter pipe 2 can be adapted to different models of the tracheostomy cannula body 11, so as to expand the application range of the adapter pipe 2.
[0039] For example, when the size of the tracheal cannula body 11 is small, the diameter of the insertion section 111 is also small, so the insertion section 111 can be inserted into the inner tube 241. When the size of the tracheal cannula body 11 is large, the diameter of the insertion section 111 is also large, so the insertion section 111 can be sleeved on the outer tube 242.
[0040] Optionally, as shown in Figures 3 to 4 The tracheal cannula 1 further comprises a fixing wing 14 arranged on the outer side of the tracheal cannula body 11 and adjacent to the other end of the tracheal cannula body 11. The fixing wing 14 can be pasted with a medical adhesive tape to fix the tracheal cannula 1, thereby improving the firmness of the tracheal cannula 1.
[0041] In some embodiments, as shown in Figures 3 to 4 The adapter tube 2 comprises a first tube 24, a second tube 25 and a third tube 26, the first tube 24, the second tube 25 and the third tube 26 are in communication with each other, the third tube 26 is arranged at the connection position of the first tube 24 and the second tube 25, the axis of the first tube 24 is substantially orthogonal to the axis of the second tube 25, one of the first tube 24 and the second tube 25 is substantially parallel to the third tube 26, the first port 21 is formed on the first tube 24, the second port 22 is formed on the second tube 25, and the third port 23 is formed on the third tube 26. It can be understood that the adapter tube 2 is substantially in the structure of a straight elbow, and the upper airway patency evaluation device of the embodiment of the present application sets the adapter tube 2 to the above structure, which can facilitate the processing and manufacturing of the adapter tube 2.
[0042] Optionally, as shown in Figure 1 The upper airway patency evaluation device further comprises an extension tube 5, one end of the extension tube 5 is inserted and fixed with the third tube 26, and the other end of the extension tube 5 is inserted and fixed with the air pressure detector 4. It can be understood that the extension tube 5 is a flexible tube, the air pressure detector 4 communicates with the adapter tube 2 through the extension tube 5, and the extension tube 5 is inserted with the adapter tube 2 and the air pressure detector 4, which can improve the convenience of using the air pressure detector 4.
[0043] For example, the air pressure detector 4 can be a differential pressure instrument.
[0044] Optionally, as shown in Figure 4 The voice one-way valve 3 comprises an end cap 31 and a one-way valve piece, the one-way valve piece is installed on one end of the end cap 31, and the end cap 31 is detachably sleeved on the second tube 25. Thus, the assembly and disassembly of the voice one-way valve 3 and the adapter tube 2 can be facilitated.
[0045] For example, the end cap 31 can be adapted to the other end of the tracheal cannula body 11, so that when the adapter tube 2 is removed, the voice one-way valve 3 can be assembled to the tracheal cannula 1 to improve the compatibility of the voice one-way valve 3.
