Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a timing device for a buoy type oxygen flow meter. Background Art

[0002] In the medical field, oxygen supply is one of the key links in the patient treatment process, especially in respiratory departments, intensive care units, operating rooms and other places. It is very important to provide patients with accurate and continuous oxygen supply. To achieve this goal, the medical equipment industry has developed a variety of devices for monitoring and controlling oxygen flow, among which the float-type oxygen flow meter has been widely used due to its intuitive and simple characteristics.

[0003] The float oxygen flow meter is a medical device used to accurately monitor and control the oxygen flow. It usually consists of a float, a flow tube, a flow control valve, an air inlet and an air outlet. Its working principle is based on the change of buoyancy: when oxygen flows in from the air inlet, a certain flow rate will be formed in the flow tube, which in turn pushes the float to move up and down in the tube. The position of the float is directly related to the flow rate of oxygen. By observing the position of the float in the flow tube, medical staff can intuitively understand the real-time flow of oxygen.

[0004] However, with the continuous improvement of medical services and the change of billing methods, hospitals have gradually changed their billing methods for oxygen supply from traditional per-bottle billing to per-oxygen inhalation time billing. This billing method requires accurate recording of the patient's oxygen inhalation time for cost accounting. At present, hospitals usually use the method of nurses manually recording oxygen inhalation time to calculate costs. Due to the possible errors in manual recording, the timing difference between nurses and patients may lead to inaccurate billing, which in turn leads to disagreements between doctors and patients. In addition, the correct estimation of oxygen inhalation time is of great significance to the patient's treatment effect. If the timing is inaccurate, the patient may not have enough or too long oxygen inhalation time, which will affect the treatment effect. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0033] See also Figure 1 and Figure 2 In a preferred embodiment of the utility model, based on the above problems existing in the prior art, a timing device for a buoy-type oxygen flow meter is provided. The buoy-type oxygen flow meter has a flow body and a flow tube arranged above the flow body, and a buoy is built in the flow tube;

[0034] Among them, when the flow regulating valve of the oxygen flow meter is rotated to close, the buoy will default to the initial position.

[0035] When the flow control valve is rotated and opened, oxygen flows into the flow tube, and the buoy can rise or fall accordingly with the increase or decrease of the flow rate by using the principle of buoyancy. If the oxygen flow rate increases, the buoy will rise; conversely, if the oxygen flow rate decreases, the buoy will fall.

[0036] The timing device includes:

[0037] The device body 1 has a first through hole 2, so that the flow tube can be passed through the first through hole 2 and the bottom surface of the device body 1 is placed on the upper part of the flow body;

[0038] The device body 1 is equipped with a controller 3 and an infrared remote control module 4 electrically connected to the controller 3, a laser transmitter 5, an ambient light detection sensor 6, a power module 7 and a display screen 8;

[0039] The laser emitter 5 and the ambient light detection sensor 6 are installed on the surface of the device body 1 and are located on opposite sides of the first through hole 2, so that when the flow tube is inserted into the first through hole 2, the laser emitter 5 and the ambient light detection sensor 6 are located on the same horizontal plane as the initial position of the buoy.

[0040] Specifically, the laser transmitter 5 and the ambient light detection sensor 6 perform timing by determining whether the buoy blocks the light signal.

[0041] When the buoy does not block the light signal between the laser transmitter 5 and the ambient light detection sensor 6, the timing mode is triggered;

[0042] When the buoy blocks the light signal between the laser transmitter 5 and the ambient light detection sensor 6, the timing pause mode is triggered.

[0043] The power module 7 provides power support for the entire timing device. The power module 7 includes an external power supply interface and / or a built-in battery; the external power supply interface can be connected to an external power line; the built-in battery can be a rechargeable battery or a dry cell.

[0044] When the controller 3 is powered on, the device is in standby mode.

[0045] The device also includes an infrared remote control module 4 for receiving external infrared remote control signals so that the user can remotely operate and control the timing device. The infrared remote control signal can be used to control the switch of the timing device. When the infrared remote control signal is received, the device exits the standby state and enters the power-on state.

[0046] After entering the power-on state, the display screen 8 displays the first interface, which is a timing pause interface.

[0047] Exemplarily, the timing value of the timing pause interface is expressed in days, hours, minutes, and seconds. At this time, the timing value defaults to 0 0000 00:00.

[0048] When the flow regulating valve of the oxygen flow meter rotates from closed to open and oxygen absorption begins, the buoy rises, the laser beam emitted by the laser transmitter 5 will not be blocked by the buoy, the ambient light detection sensor 6 detects the laser beam, and then the controller 3 controls the display screen 8 to display the second interface, which is the timing interface.

[0049] When the flow regulating valve of the oxygen flow meter is closed and oxygen inhalation stops, the buoy will drop to the default initial position, that is, the laser beam emitted by the laser transmitter 5 will be blocked by the buoy, and the ambient light detection sensor 6 does not detect the laser beam. The controller 3 controls the display screen 8 to display the first interface again, but the timing pause interface displays the actual timing value at this time.

[0050] The timing device of the utility model does not need to change the design of the oxygen flow meter. The device can be directly put on the flow tube as a whole. The position change of the buoy in the flow tube can be monitored in real time through the laser emitter 5 and the ambient light detection sensor 6, so as to accurately calculate the oxygen absorption time and greatly reduce the timing error.

[0051] At the same time, through the display screen 8 and other interfaces, the current oxygen inhalation time can be intuitively viewed, thereby more accurately understanding the oxygen inhalation situation.

[0052] The timing function of the device can be realized by using a built-in timer of the controller 3, or by an external timing module.

[0053] As a preferred embodiment, the infrared remote control module 4 includes an infrared receiving sensor 41 and a remote controller 42 , and the infrared receiving sensor 41 is electrically connected to the controller 3 .

[0054] Specifically, an infrared receiving sensor 41 is installed at a suitable position of the device body 1 to receive infrared remote control signals from a remote controller 42 .

[0055] The remote controller 42 includes a plurality of control buttons or an input device such as a touch screen, through which the user can select different functions or parameter settings. When the user presses a button on the remote controller 42, the remote controller will send a corresponding infrared remote control signal, which includes the operation that the user wants to perform.

[0056] When the infrared receiving sensor 41 receives the infrared remote control signal from the remote controller 42, it converts it into an electrical signal and transmits the received infrared signal to the controller 3 for processing. After receiving the electrical signal, the controller 3 performs corresponding operations according to the analyzed signal.

[0057] As an example but not limitation, the user can configure the power switch of the device of the utility model through the remote control 42. When the remote control 42 sends a corresponding infrared remote control signal, the controller 3 receives the electrical signal transmitted by the infrared receiving sensor 41, controls the device to start, and controls the display screen 8 to display the timing pause interface.

[0058] As a preferred embodiment, the remote controller 42 is provided with a control button (not shown in the figure);

[0059] The control buttons include any one or more of a power switch button, a timing stop button, and a reset button.

[0060] Specifically, the control button set includes but is not limited to the following types: a power switch button, a timing stop button, and a reset button.

[0061] Specifically, the power switch button allows users to remotely control the power on and off status of the device, greatly improving the flexibility of use;

[0062] The timing stop button can interrupt the ongoing timing task at any time; the timing stop button of the device of the utility model can be an "OK" button. When the patient stops the timing and ends the oxygen inhalation, the "OK" button is pressed. At this time, the timing value displayed on the display screen 8 is the current oxygen inhalation time.

[0063] The reset button can restore the timing to the default value with one click, so as to facilitate the oxygen inhalation timing for the next time or the next patient.

[0064] By pressing the power switch button, the device of the utility model is controlled to switch from the standby state to the power-on state.

[0065] After the controller 3 is powered on, the device is in standby mode.

[0066] In the standby state, the infrared receiving sensor 41 can receive an infrared remote control signal from the remote controller 42 .

[0067] When the device receives the infrared remote control signal, the device switches to the power-on state.

[0068] In the power-on state, the controller 3 supplies power to the laser emitter 5, the ambient light detection sensor 6 and the display screen 8. At this time, the laser emitter 5 continuously emits the laser beam; the ambient light detection sensor 6 continuously detects whether the laser beam is blocked; the controller continuously displays whether the value of the ambient light detection sensor 6 is greater than the preset value, and starts or continues timing when it is greater than the preset value, and pauses or stops timing when it is less than the preset value.

[0069] The timing mode of the utility model is triggered only according to whether oxygen is given, that is, the flow regulating valve of the oxygen flow meter is opened, the buoy rises, and the timing mode is triggered; the flow regulating valve of the oxygen flow meter is closed, the laser emitter 5 and the ambient light detection sensor 6 are blocked by the buoy, and the timing pause mode is triggered.

[0070] The timing stop button is used to stop the oxygen inhalation after the oxygen inhalation is stopped. In fact, before the timing stop button is pressed, the flow regulating valve of the oxygen flow meter has been closed, and the timing process has just ended. By pressing the timing stop button, it is distinguished from the timing pause.

[0071] The above remote control is held and operated by medical staff.

[0072] It should be noted that no physical buttons are provided on the accessible surface of the device of the utility model, so as to avoid inaccurate oxygen inhalation timing caused by the oxygen user turning off the power of the timing device or pausing / stopping the timing during the oxygen inhalation process in traditional timing devices with physical buttons.

[0073] As a preferred embodiment, the display interface of the display screen 8 includes the current timing mode and the timing value;

[0074] The timing mode includes the timing pause mode or the timing mode.

[0075] Specifically, the display screen 8 includes a first interface and a second interface;

[0076] When the laser beam emitted by the laser emitter 5 is blocked by the buoy, the display screen 8 displays the first interface; the first interface includes the timing pause mode and the current timing value; Figure 3 As shown, the timing value initially defaults to 0 00 00 00:00.

[0077] When the laser beam emitted by the laser emitter 5 is not blocked by the buoy, the display screen 8 displays the second interface; the second interface includes a timing mode, triggering the built-in timing function of the controller 3 and displaying the timing value in real time, such as Figure 4 shown.

[0078] When the laser beam is blocked by the buoy again, the timing is paused; at the same time, the display screen 8 displays the first interface, that is, the timing mode is changed to the timing pause mode, but the timing value remains unchanged, such as Figure 5 shown.

[0079] The display screen 8 can be an LCD display screen, an OLED display screen or other display screens.

[0080] As a preferred embodiment, the controller 3 and the display screen 8 are located on the same side of the first through hole 2 , and the display screen 8 and the power module 7 are located on different sides of the first through hole 2 .

[0081] As a preferred embodiment, the controller 3 is installed on the device body 1 through a connecting column 9.

[0082] Specifically, the infrared receiving sensor 41 is installed on the lower surface of the device body 1 and is located below the power module 7 .

[0083] It should be noted that, in the device of the present invention, except for the positions of the laser emitter 5 and the ambient light detection sensor 6, the positions of other modules can be adaptively adjusted as needed.

[0084] As a preferred embodiment, the shape of the first through hole 2 is complementary to the shape of the upper portion of the flow body.

[0085] Specifically, during the installation process, the device body 1 is put on the flow tube from the top of the flow tube to ensure that the flow tube slowly and steadily passes through the first through hole 2. After the first through hole 2 completely passes through the flow tube, it is slightly pressed to the bottom, and the bottom surface of the device body 1 is placed on the upper part of the flow body.

[0086] The shape and size of the perforations completely match the shape of the upper portion of the flow body, ensuring that the bottom surface of the device body 1 can be placed stably and horizontally on the upper portion of the flow body.

[0087] As a preferred embodiment, the power module 7 includes an external power supply interface and / or a built-in battery.

[0088] As a preferred embodiment, the invention further comprises:

[0089] The communication module 10 is electrically connected to the controller 3 .

[0090] Furthermore, the communication module 10 has built-in WiFi communication to enable the device of the utility model to be embedded in an external platform, such as an existing nurse work software or platform, to achieve remote data interaction and management.

[0091] By setting the communication module 10, the timing process can be derived, and the timing process can be the total value of the timing of this oxygen inhalation. The timing process can also be the details of the timing, and the details include the timing time of each timing start / pause.

[0092] Furthermore, in the external platform, the exported timing process can be bound to the patient identification, and each patient identification can be bound to one or more exported timing processes, so that oxygen inhalation is billed according to the accumulated timing.

[0093] The controller 3 of the present invention can adopt an Aduinuo nano main control board.

[0094] In the above preferred embodiment, the operation process of the timing device of the utility model is as follows:

[0095] First, put the timing device on the glass tube of the oxygen flow meter and press it slightly to ensure the device is stable;

[0096] Then, use an external power cord or built-in battery to power on the controller 3 (Aduino Nano main control board), and the device is in standby mode;

[0097] After the controller 3 is started, it will continuously detect whether the infrared receiving sensor 41 receives the infrared remote control signal from the remote controller 42 .

[0098] If no infrared remote control signal is received, the device remains in standby mode and continues to detect infrared remote control signals.

[0099] When the power switch button on the remote controller is pressed, the infrared receiving sensor 41 receives the infrared remote control signal, the controller 3 controls the device to switch from the standby state to the power-on state, and the Aduino Nano main control board supplies power to other modules. At this time, the display screen 8 displays the timing pause mode interface (first interface), and the default is 0 00 00 00:00;

[0100] In the power-on state, the controller 3 will detect in real time whether the value of the ambient light detection sensor 6 is greater than the preset value:

[0101] If the flow regulating valve is opened, it means that oxygen inhalation has started. At this time, since the buoy of the oxygen flow meter floats up, the laser beam emitted by the laser emitter 5 will not be blocked by the buoy, and the value of the ambient light detection sensor 6 is greater than the preset value, the device will automatically determine that the oxygen inhalation state has started, and the timing will start; at the same time, the display screen 8 switches to the timing mode interface (the second interface) and synchronously displays the timing time.

[0102] If the flow regulating valve is closed, it means that oxygen inhalation is paused or stopped, the buoy falls back to the initial position, blocking the laser beam, and the value of the ambient light detection sensor 6 is not greater than the preset value. The device will automatically judge that the oxygen inhalation state is paused, and the timing is paused or stopped; at the same time, the display screen 8 switches to the timing pause mode interface (first interface) and retains the timing time.

[0103] When the flow regulating valve is opened again, oxygen inhalation continues and the timing continues.

[0104] When the user finishes oxygen inhalation and closes the flow regulating valve, he presses the "OK" button on the remote controller 42 to stop the timing. At this time, the display screen 8 keeps displaying the timing pause interface.

[0105] If the user needs to turn off the device, the user can press the power switch button on the remote controller 42 again and the device will turn off.

[0106] The advantages or beneficial effects of adopting the above technical solution are: the utility model can monitor the position changes of the buoy in the flow tube in real time by integrating the laser emitter and the ambient light detection sensor, so as to accurately calculate the oxygen inhalation time, greatly reduce the timing error, and ensure the fairness and accuracy of the billing.

[0107] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of this specification and illustrations should be included in the protection scope of the present invention.
