Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an artificial airway humidifier. Background Technology

[0002] The establishment of an artificial airway affects the body's normal regulation of inhaled gases, impairing the normal respiratory tract's function of warming and humidifying inhaled gases. This can easily lead to airway dryness, thickened sputum, and complications such as airway obstruction, airway mucosal damage, atelectasis, and pulmonary infections. Relevant guidelines indicate that patients with indwelling artificial airways should undergo proper airway humidification management to increase the temperature and humidity of inhaled gases, moisten the airway mucosa, maintain normal ciliary movement, and thin sputum.

[0003] Currently, heated humidifiers used in clinical practice require the delivery of gas inhaled through the breathing circuit to the artificial airway. This results in a relatively long distance between the artificial airway and the humidifier. Before the heated and humidified gas is delivered into the patient's airway, it forms small liquid droplets due to the temperature difference between the inside and outside of the tube. These droplets eventually condense in the breathing circuit tube, forming flowing condensate. This condensate creates favorable conditions for bacterial growth. Over time, the number of bacteria in the condensate will gradually increase, which can lead to lung infections in patients. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Please refer to Figure 1 As shown, an artificial airway humidifier includes a control component, a humidification device 110, a heating device 130, a first connecting pipe 111, a second connecting pipe 150, a connecting pipe 170, a sensor 171, and a one-way control device 173. The humidification device 110 is externally connected to an oxygen supply line. One end of the first connecting pipe 111 is connected to the humidification device 110, and the other end is connected to the second connecting pipe 150. The end of the second connecting pipe 150 away from the first connecting pipe 111 passes through the peripheral wall of the connecting pipe 170 and is connected to the connecting pipe 170. The sensor 171 is mounted on the connecting pipe 170; in this embodiment, the sensor 171 is a temperature sensor. The one-way control device 173 is mounted on one end of the connecting pipe 170 and is a breathing valve-type one-way control valve. The other end of the connecting pipe 170 is used to connect to the artificial airway. The heating device 130 is connected to the bottom of the humidification device 110. The control component is located on one side of the humidification device 110, and the sensor 171, the humidification device 110 and the heating device 130 are all electrically connected to the control component.

[0028] When using this device to humidify and heat oxygen, the external oxygen supply system must first be connected to the humidifier 110, and a certain amount of humidifying liquid must be injected into the humidifier 110. Medical personnel operate the humidifier via the control component and input the desired temperature value. Oxygen enters the humidifier 110 under pressure, and the humidifier 110 humidifies the oxygen; the heating device 130 heats the oxygen and humidifying liquid within the humidifier 110. The sensor 171 continuously monitors the temperature of the oxygen in the connecting tube 170, and the control component displays this information in real time. Once the oxygen temperature in the connecting tube 170 reaches the preset temperature value, medical personnel can connect the end of the connecting tube 170 without the one-way control 173 to the artificial airway to supply oxygen to the patient. The one-way control 173 closes when the patient inhales and opens when the patient exhales, reducing humidifying liquid loss and enhancing the humidification effect. Preferably, a rubber plug is provided at the end of the one-way control component 173 away from the connecting tube 170. When the artificial airway humidifier is not in use, the rubber plug seals the one-way control component 173 to prevent dust from entering the interior of the artificial airway humidifier.

[0029] It should be noted that the control components consist of an existing PLC controller, input keys, a display screen, and a mounting housing. This part is existing technology, and its principle and structure will not be described in detail here. The PLC controller, input keys, and display screen are all mounted on the mounting housing, which is connected to the humidification device 110 by bolts.

[0030] Preferably, one end of the first connecting tube 111 passes through the peripheral wall of the second connecting tube 150 and is connected to the second connecting tube 150. The end of the second connecting tube 150 away from the connecting tube 170 is provided with a rubber stopper for opening and closing the second connecting tube 150, the peripheral wall of which abuts against the inner wall of the second connecting tube 150. When the patient needs to use a ventilator, medical staff can remove the rubber stopper from the second connecting tube 150 and connect the end of the second connecting tube 150 to the ventilator.

[0031] Preferably, a one-way control element 173 is also provided at the end of the second connecting pipe 150 away from the connecting pipe 170, and the rubber plug is connected to the second connecting pipe 150 through the one-way control element 173.

[0032] Please refer to Figure 2As shown, the humidifier 110 includes a bottle body 112 and a bottle cap 113 mounted on the bottle body 112, with the bottle body 112 and bottle cap 113 threaded together. The bottle body 112 is used to hold the humidifying liquid. The bottle cap 113 is provided with a connector 115 for connecting an external oxygen supply line; the connector 115 is inserted into the oxygen supply line to complete the connection. An extension tube 117 is provided inside the bottle body 112. One end of the extension tube 117 is connected and snapped into the end of the connector 115 located inside the bottle cap 113. A certain gap is provided between the end of the extension tube 117 away from the connector 115 and the bottom of the bottle body 112 to facilitate oxygen entering the interior of the bottle body 112 through the extension tube 117. After the oxygen enters the interior of the bottle body 112, it comes into contact with the humidifying liquid, thereby increasing the humidity of the oxygen.

[0033] Preferably, the bottle cap 113 is also provided with a liquid inlet 119, and a plug is detachably installed on the liquid inlet 119. When the patient needs to increase the amount of medication for treatment or needs to increase the amount of humidifying fluid, medical staff can remove the plug from the liquid inlet 119 and add the medication or humidifying fluid into the bottle 112 using a syringe or other tools. After adding the fluid, the plug must be reinstalled at the liquid inlet 119 to avoid contamination of the liquid in the bottle 112.

[0034] Please refer to Figure 3 The heating device 130 includes a heating element 131, a mounting base 133, and a heat insulation pad 135. The upper end of the mounting base 133 is open and connected to the bottom of the bottle body 112. The heating element 131 is a conventional heating wire, which is fixedly connected to the inner side of the mounting base 133. The heat generated by the heating element 131 can heat the bottle body 112 and the liquid and gas inside the bottle body 112. The heat insulation pad 135 is laid on the inner side of the mounting base 133 to insulate the heat generated by the heating element 131, preventing the mounting base 133 from being heated and causing injury to the human body upon contact.

[0035] Furthermore, to further prevent cooling water from remaining on the pipe wall, in this embodiment, the first connecting pipe 111 and the second connecting pipe 150 are inclined together, with the included angle between them preferably being 45°. The height of the end where the first connecting pipe 111 connects to the connecting pipe 170 is higher than the height of the connection point between the first connecting pipe 111 and the second connecting pipe 150. Please refer to [reference needed] for details. Figure 4 The condensate on the walls of the first connecting pipe 111 and the second connecting pipe 150 will flow into the bottle 112 along the pipe walls, thus preventing bacterial growth.

[0036] Please refer to Figure 1As shown, the second connecting pipe 150 includes two straight pipe sections 151 and an extension section 153. The two straight pipe sections 151 are connected by the extension section 153, and the three are detachably and sealed together. This design avoids the situation where the second connecting pipe 150 is not long enough during actual use. When there is condensation on the wall of the extension section 153, the extension section 153 can be removed for cleaning.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
