AI Technical Summary
When the existing warm and humidification tee pipe needs a large air flow rate when the air incision patients require a large air flow, the built-in check valve at the outlet cannot replenish the air needed for the patient to breathe, resulting in some patients having symptoms such as chest tightness.
An improved temperature and humidity tee pipe is designed. By setting a bar groove and a return air channel at the outlet end of the air conduit, the combination of a one-way duckbill valve and elastic member is used to realize that when the patient inhales, the external air enters the return air channel through the bar groove and enters the gas temperature and humidifier to supplement the air flow.
It effectively supplements the patient's inhalation air flow, improves the comfort of air incision patients during the treatment process, reduces the incidence of high airway reactions, and improves the protective effect of the airway by reducing the intake speed and increasing the sliding layer.

Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical devices, and in particular to an improved temperature and humidification three-way pipe. Background Art
[0002] The contents of this section merely provide background information related to the present application and may not constitute prior art.
[0003] Tracheotomy is a common surgery that is applicable to a variety of conditions. It is performed by cutting open the trachea in the patient's neck and inserting a metal or silicone cannula to relieve dyspnea caused by laryngeal origin, respiratory dysfunction or retention of lower respiratory tract secretions. Post-tracheotomy care includes keeping the inner cannula open, maintaining the lower respiratory tract open, preventing the cannula from being blocked or dislodged, and preventing infection. In addition, post-tracheotomy care also includes replacing the inner cannula, maintaining a suitable temperature and humidity in the room, preventing lung infection, and atomizing and suctioning the patient's sputum when necessary.
[0004] In actual use, after the patient is intubated for tracheotomy, the air inhaled by the patient needs to be humidified to prevent the patient from inhaling too dry and cold air, which eventually leads to dry airways or induces underlying diseases leading to airway hyperresponsiveness. Therefore, for the three-way cannula used for tracheotomy patients, the bottom end is inserted into the patient's trachea, the air inlet end at the top is connected to the humidifier to humidify the inhaled gas, and the air outlet end on the other side of the top is built with a one-way valve to avoid cross-infection between patients.
[0005] However, the above-mentioned related technologies have the following defects: the air volume of the patient's breathing is completely dependent on the air intake at the air inlet end. When the patient needs a larger air volume, due to the one-way valve provided in the air outlet end, the air outlet end cannot replenish the air required for the patient's breathing, which causes chest tightness in some patients, causing great discomfort to the patients.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0031] The following reference Figures 1 to 6 This application is described in further detail.
[0032] Reference Figure 1 An improved humidification three-way tube includes a tracheostomy tube 1 and an airway tube 2. As an embodiment of the present application, the tracheostomy tube 1 and the airway tube 2 are perpendicular to each other, the bottom end of the tracheostomy tube 1 is used to communicate with the patient's trachea, and the top end of the tracheostomy tube 1 is connected to the airway tube 2. One end of the airway tube 2 is set as an air inlet end 21, and the other end is set as an air outlet end 22. A gas humidifier 23 is connected to the air inlet end 21.
[0033] Reference Figure 1 , 2 A mounting ring 3 is provided on the air outlet end 22, the outer wall of the mounting ring 3 is slidably connected to the inner wall of the air guide pipe 2, and a one-way duckbill valve 31 is fixedly provided on the side of the mounting ring 3 away from the air inlet end 21. Figure 2 As shown, a one-way conductive strip opening is provided at the outer end of the one-way duckbill valve 31, and the airflow passes through the tube throat of the air duct 2 and can be discharged from the strip opening provided at the outer end of the one-way duckbill valve 31, but the external air cannot enter the air duct 2 through the strip opening on the one-way duckbill valve 31.
[0034] Among them, refer to Figure 2 , 3A strip groove 4 is provided on the inner wall of the tube hole of the air outlet end 22, and the length of the strip groove 4 is less than the length of the mounting ring 3. A return air channel 41 is also provided in the inner wall of the tube wall of the air guide tube 2, and one end of the return air channel 41 is connected to the strip groove 4, and the other end is connected to the gas humidifier 23. An elastic member 42 is provided on the air guide tube 2, and the elastic member 42 is used to drive the mounting ring 3 to move in a direction away from the air inlet end 21 so that the mounting ring 3 can completely close the opening of the strip groove 4.
[0035] Among them, refer to Figure 2 , 3 A strip block 43 is fixedly arranged on the outer wall of the mounting ring 3, the strip block 43 protrudes from the outer wall of the mounting ring 3, and the strip block 43 is slidably arranged in the strip groove 4. As an embodiment of the present application, refer to Figure 3 The elastic member 42 is configured as a compression spring, and the elastic member 42 is disposed in the strip groove 4. One end of the elastic member 42 is fixedly connected to the side wall of the strip block 43, and the other end is fixedly connected to the inner wall of the strip groove 4. Under normal conditions, the elastic member 42 extends outward, pushing the strip block 43 outward, so that the outer side surface of the strip block 43 contacts the end surface of the strip groove 4 away from the air inlet end 21, so that the strip block 43 can close the opening of the strip groove 4, preventing external air from entering the strip groove 4.
[0036] Reference Figure 3 A guide groove 44 is provided on the inner side wall of the strip groove 4 along the length direction of the strip groove 4, a guide block 45 is slidably arranged in the guide groove 44, and the guide block 45 is fixedly connected to the side wall of the strip block 43, that is, the guide block 45 protruding from the side wall of the strip block 43 is fixedly arranged on the side wall of the strip block 43, as shown in FIG. Figure 2 and Figure 3 When the bar block 43 slides in the bar groove 4, the guide blocks 45 arranged on both sides of the bar block 43 can guide the sliding of the bar block 43 to a certain extent, thereby preventing the bar block 43 from being stuck and unable to move in the bar groove 4 due to misalignment, thereby improving the reliability and safety of the device during actual use, and further improving the protection effect on patients.
[0037] When the guide block 45 is slidably disposed in the guide groove 44, the top wall of the strip block 43 does not contact the top wall of the strip groove 4, that is, a gap is left between the top wall of the strip block 43 and the top wall of the strip groove 4, allowing airflow to pass through the gap.
[0038] Reference Figure 2 , 3 An air intake channel 5 is opened inside the strip block 43, and the air intake channel 5 is set to be L-shaped. One end of the air intake channel 5 is opened on the side wall of the strip block 43 close to the one-way duckbill valve 31, and the other end is opened on the top wall of the strip block 43 close to the return air channel 41.
[0039] As an implementation method of this application, refer to Figure 2 , 3 , only one air intake passage 5 is provided. As another possible implementation manner of the present application, multiple air intake passages 5 may be provided.
[0040] In addition, as an embodiment of the present application, a sliding layer is covered on the side walls of the guide block 45 and the strip block 43. The material of the sliding layer can be set to polytetrafluoroethylene, which has a good anti-corrosion effect and can maintain a low friction coefficient during long-term use.
[0041] Reference Figure 2 , 3 , multiple strip grooves 4 are evenly opened along the circumference of the air duct 2, and a strip block 43 is slidably arranged in each strip groove 4. As an embodiment of the present application, four strip grooves 4 are evenly opened along the axis of the air duct 2, and the number of strip blocks 43 matches the number of strip grooves 4.
[0042] Reference Figure 3 , 4 A mounting hole 6 connected to the strip groove 4 is provided on the circumference of the air outlet end 22 of the air guide pipe 2 along the radial direction of the air guide pipe 2, a positioning pin 61 is slidably provided in the mounting hole 6 along the axial direction of the mounting hole 6, and a positioning hole 62 for inserting the positioning pin 61 is provided on the top of the strip block 43. When the positioning pin 61 is inserted into the positioning hole 62, the mounting ring 3 completely closes the opening of the strip groove 4.
[0043] Among them, refer to Figure 2 , 3 A boss 63 is provided at one end of the positioning pin 61 away from the positioning hole 62. The diameter of the boss 63 is larger than the diameter of the positioning pin 61. A tension spring 64 is sleeved on the positioning pin 61. One end of the tension spring 64 is fixedly connected to the outer wall of the air guide tube 2, and the other end is fixedly connected to the bottom of the boss 63.
[0044] In addition, refer to Figure 4 A protruding latch key 65 is fixedly provided on the positioning pin 61 along the axial direction of the positioning pin, and a key groove 66 for the latch key 65 to be inserted into is opened in the mounting hole 6 along the axial direction.
[0045] In actual use, when the patient does not need a larger air flow, the position of the strip block 43 in the strip groove 4 is limited by the positioning pin 61. At this time, the key 65 is located in the slot 66, which can prevent external air from entering the gas humidifier 23 through the return air channel 41.
[0046] When the patient needs a larger air flow, the positioning pin 61 is pulled to move in a direction away from the positioning hole 6. As the positioning pin 61 moves, the positioning pin 61 drives the key 65 to disengage from the key slot 66 and rotates the positioning pin 61, so that the key 65 and the key slot 66 are out of position. At this time, the lower end of the key 65 abuts against the outer periphery of the airway tube 2. When the key 65 is completely out of the key slot 66, the end of the positioning pin 61 is completely out of the positioning hole 62, thereby releasing the restriction on the position of the strip block 43. At this time, the strip block 43 can move in the strip slot 4, and the patient's inhalation volume can be effectively supplemented.
[0047] As a possible implementation of the present application, the material of the airway tube 2 is set to be transparent, which can facilitate medical staff to observe the situation inside the airway tube 2 in real time. When the patient has sputum, the medical staff can quickly observe through the transparent airway tube 2, so as to care for the patient or replace the airway tube 2 and the entire device.
[0048] As another possible implementation of the present application, the inner wall of the airway tube 2 is arranged to be spiral (not shown in the figure). Through the above arrangement, the airflow generated in the airway tube 2 during the patient's breathing process can be further guided, so that the gas flow rate of the patient breathing into the airway tube 2 is more stable, thereby further improving the protection effect of the patient's airway.
[0049] Reference Figure 5 The bottom diameter of the inner diameter of the tracheostomy tube 1 is larger than the top diameter of the inner diameter of the tracheostomy tube 1, so that the tracheostomy tube 1 can be easily connected with the patient's tracheal cannula. In actual use, the patient's tracheal cannula is mostly divided into two types, one is a plastic tracheal cannula joint, and the other is a metal tracheal cannula joint. There is a certain difference in the diameters of the two cannulae. Figure 5 As shown, the inner diameter of the tracheostomy tube 1 is set to be slightly thicker at the bottom and slightly thinner at the top, which can make it more convenient to connect the tracheostomy tube 1 to the intubation joint of the patient's trachea, thereby improving the application range of the tracheostomy tube 1.
[0050] Reference Figure 6 As another embodiment of the present application, the gas humidifier 23 can be as follows Figure 6 The gas humidifier 23 is configured to be gourd-shaped, with a small diameter on the side close to the air inlet end 21 and a large diameter on the side close to the air outlet end 22. This can effectively reduce the flow rate of the gas entering the gas humidifier 23 through the air inlet end 21, giving this part of the gas a longer time to be humidified, and further improving the protection of the patient's airway.
[0051] The implementation principle of an improved temperature and humidity three-way pipe proposed in the embodiment of the present application is:
[0052] During actual use, when the patient needs a larger amount of air to breathe, as the patient inhales, the one-way duckbill valve 31 is under pressure and moves toward the inside of the trachea 2. At this time, the strip groove 4 is opened, and the external air can enter the return air channel 41 through the strip groove 4, and then enter the gas humidifier 23, which assists the patient's breathing and can effectively supplement the patient's inhaled air volume, thereby improving the comfort of tracheostomy patients during treatment.
[0053] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
