[0002] Clinical oxygen therapy is a commonly used treatment method, mainly used to relieve hypoxia symptoms, increase arterial blood oxygen partial pressure and oxygen saturation, promote metabolism, and assist in the treatment of various diseases.

[0003] Since current clinical oxygen therapy is billed based on the specific time the patient inhales oxygen, and the existing oxygen therapy devices do not have a timer that is easy to disassemble, repair, and control for the patient, patients often stop inhaling oxygen for other reasons and may later question how many hours they have inhaled oxygen, feeling that they have been overcharged, which can easily lead to disputes. Therefore, it is necessary to provide an oxygen therapy timer to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an oxygen inhalation timer, which solves the problems mentioned in the background above.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 An oxygen inhalation timer includes a humidification bottle 1, a connecting tube 2 at the upper end of the humidification bottle 1, a flow meter 3 at the upper end of the connecting tube 2, an oxygen outlet pipe 5 on one side of the connecting tube 2, a control tube seat 6 at the end of the oxygen outlet pipe 5 away from the connecting tube 2, a timer body 7 at the center of the upper surface of the control tube seat 6, a switch button 702 at the lower end of the timer body 7 near the oxygen outlet pipe 5, mounting holes at both ends of the control tube seat 6, and a valve structure 9 at the end of the control tube seat 6 near the oxygen outlet pipe 5 through the mounting hole.

[0024] Among them, the oxygen inlet pipe 4 is provided at the middle of the back of the connecting pipe body 2, the oxygen outlet pipe 5 is provided at the end of the external thread interface pipe 501, the control pipe seat 6 is provided at the end near the oxygen outlet pipe 5 with a connector 601, the inner wall of the connector 601 is provided with an internal thread that cooperates with the external thread interface pipe 501, and the control pipe seat 6 is provided at the end away from the connector 601 with an oxygen inhalation pipe connector 602. The control pipe seat 6 is threadedly connected to the oxygen outlet pipe 5 through the connector 601, so as to facilitate the installation and disassembly of the control pipe seat 6 and the timer body 7, and facilitate the maintenance and replacement of the timer body 7 in the future.

[0025] The valve structure 9 includes a ball 901, a rotating shaft 902, a cam 903, and a lever 904. The ball 901 is located inside the control tube seat 6 and has a through hole. The lower end of the rotating shaft 902 is connected to the ball 901, and the upper end of the rotating shaft 902 passes through the mounting hole and is connected to the cam 903. The end of the lever 904 is connected to the end side wall of the cam 903. Initially, the ball 901 is located inside the control tube seat 6, and both ends of the through hole on the ball 901 are blocked by the inner wall of the control tube seat 6. Oxygen cannot pass through the control tube seat 6, and the patient cannot inhale oxygen. When the patient needs oxygen... When oxygen is inhaled, the patient can move the lever 904, causing the cam 903 to rotate. During the rotation of the cam 903, its front end will contact and press the switch button 702, thus starting the timer. At the same time, the rotation of the cam 903 drives the ball 901 to rotate synchronously through the rotating shaft 902, opening the through hole on the ball 901, allowing the patient to inhale oxygen. This allows the timer to start simultaneously with oxygen inhalation. Similarly, when the patient moves the lever 904 in the opposite direction to stop oxygen inhalation, the cam 903 rotates in the opposite direction, pressing the switch button 702 again to turn off the oxygen inhalation. The structure is simple and easy for patients to understand and operate.

[0026] The cam 903 is provided with a limiting protective shell 8 on its outer side. One end of the limiting protective shell 8 is connected to the timer body 7, and the end of the limiting protective shell 8 away from the timer body 7 is provided with a limiting slot 801. The rotating shaft 902 passes through the lower wall of the limiting protective shell 8 and is rotatably connected to the limiting protective shell 8. By providing the limiting protective shell 8, the switch button 702 and the cam 903 can be effectively protected. By providing the limiting slot 801 on the limiting protective shell 8, the rotation range of the toggle lever 904 can be effectively limited, thereby limiting the rotation angle of the cam 903, making it easier for the elderly to operate.

[0027] The timer body 7 has a display screen 701 on the front and a charging interface 703 on the lower back. The control tube seat 6 has a flow regulating valve 10 installed at the end away from the valve structure 9 through a mounting hole. The display screen 701 can be used to display the oxygen inhalation time, and the oxygen output can be effectively adjusted by rotating the flow regulating valve 10.

[0028] The working principle is as follows: When a patient needs oxygen, the patient can move the lever 904, which drives the cam 903 to rotate. During the rotation of the cam 903, its front end will contact and press the switch button 702, thus starting the timer. At the same time, the rotation of the cam 903 drives the ball 901 to rotate synchronously through the rotating shaft 902, opening the through hole on the ball 901, allowing the patient to inhale oxygen. This allows the timer to start while the patient is inhaling oxygen. Similarly, when the patient moves the lever 904 in the opposite direction to stop inhaling oxygen, the cam 903 rotates in the opposite direction, pressing the switch button 702 again to turn off the oxygen. The structure is simple and easy for patients to understand and operate.

[0029] Furthermore, by setting a limit protective shell 8, the switch button 702 and cam 903 can be effectively protected. By opening a limit groove 801 on the limit protective shell 8, the rotation range of the toggle lever 904 can be effectively limited, thereby limiting the rotation angle of the cam 903, which is convenient for elderly people to operate. The control tube seat 6 is threadedly connected to the oxygen outlet pipe 5 through the connector 601, which makes it easy to install and disassemble the control tube seat 6 and the timer body 7, and facilitates the maintenance and replacement of the timer body 7 in the future.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
