Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an oxygen flow meter control device. Background Art

[0002] The oxygen flow meter is an instrument commonly used in hospitals. It can measure the flow of oxygen, make a certain measurement of oxygen, and make the use of oxygen more convenient.

[0003] In the use of oxygen flow meter, there are the following problems:

[0004] On the one hand, the existing common oxygen flow meter control valve can generally be adjusted freely, which leads to some patients not following the doctor's advice to adjust the oxygen flow by themselves, which poses certain safety hazards and has low reliability.

[0005] On the other hand, during the patient's oxygen inhalation process, the oxygen flow rate needs to be adjusted according to the patient's condition, or during the oxygen cessation process, the nasal cannula needs to be disconnected first and then the oxygen flow rate needs to be adjusted. This step is often omitted in clinical work, and adjustments are made directly. Sometimes negligence causes the flow meter regulator to be adjusted in the wrong direction, causing the patient to inhale high-flow oxygen for a short time, causing discomfort to the patient, and in severe cases, pulmonary barotrauma. Utility Model Content

[0006] In view of this, the utility model aims to provide an oxygen flow meter control device with a prompt function, which at least solves one of the technical problems in the related art to a certain extent.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] An oxygen flow meter control device with a prompting function comprises a flow meter body and a regulating valve, a float flow meter, a central oxygen supply pipeline interface and an oxygen output pipeline arranged on the flow meter body, wherein the float flow meter, the central oxygen supply pipeline interface and the oxygen output pipeline are connected with the regulating valve;

[0009] The flow meter is also provided with a regulator, the regulator is provided with an openable and closable outer cover, the contact portion between the outer cover and the outer edge of the regulator is provided with a touch control portion, the outer cover is provided with an audio playing component, an audio playing switch and a power supply for providing power to each component;

[0010] An air flow sensor for sensing gas reflux is provided on the inner wall of the oxygen output pipeline, which is used to sense the change of gas reflux and control the action of the audio playback switch.

[0011] Further optimization, the audio playback switch is connected to the airflow sensor, and the power supply is connected in series with the audio playback switch and the audio playback component to form a loop for broadcasting a voice prompt when the audio playback switch is triggered.

[0012] Further optimization is that when the outer cover is in contact with the regulator, the outer cover disconnects the audio playback component from the power supply through the touch portion; when the outer cover is separated from the regulator, the touch portion automatically resets to connect the battery to the audio playback component and broadcast a voice prompt.

[0013] Optionally, when the outer cover abuts against the regulator, the touch control unit disconnects the audio playing component from the power supply by squeezing or short-circuiting the circuit.

[0014] Further optimization, the regulator includes an adjusting knob and a chassis with a scale, and a pointer is provided on the adjusting knob, and when the adjusting knob is rotated, the pointer coincides with the corresponding scale on the chassis. By rotating the knob to adjust the clearance of the regulating valve, and reflecting it on the corresponding scale of the chassis, the size of the oxygen flow rate can be adjusted more accurately to prevent twisting in the wrong direction.

[0015] Furthermore, the chassis is recessed, and a protrusion for touching is provided at the center of the adjusting knob, so that medical staff can turn the adjusting knob by hand.

[0016] Further optimized, the oxygen output pipeline is connected to the oxygen delivery equipment for oxygen delivery.

[0017] Further optimization, the oxygen delivery device is a nasal catheter.

[0018] For further optimization, the scale on the chassis is marked with numbers.

[0019] Further optimization also includes a locking device arranged at the lower end of the regulator for locking the outer cover and the regulator together.

[0020] The beneficial effects of the utility model are:

[0021] The utility model provides a flow meter with a regulator and an outer cover. The touch control part on the outer cover controls the connection of the circuit. When the outer cover is opened, it indicates that the medical staff is ready to adjust. The airflow sensor senses the change of gas reflux and controls the action of the audio playback switch. If the nasal cannula is not disconnected, a voice reminder is given to prevent errors that may occur when adjusting directly.

[0022] There is a pointer on the adjustment knob and a scale on the chassis. By rotating the knob and adjusting it and reflecting it on the scale on the chassis, the oxygen flow rate can be adjusted more accurately to achieve a better oxygen therapy effect.

[0023] Furthermore, a locking device is provided under the regulator, which can only be opened by medical staff with the key to prevent the patient himself or unrelated personnel from making irregular adjustments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following specific embodiments are given to further clearly, completely and in detail illustrate the technical solution of the utility model. This embodiment is the best embodiment based on the technical solution of the utility model, but the protection scope of the utility model is not limited to the following embodiments.

[0029] Example 1

[0030] An oxygen flow meter control device with a prompting function, comprising a flow meter body 7 and a regulating valve arranged on the flow meter body 7, a float flow meter 1, a central oxygen supply pipeline interface 2 and an oxygen output pipeline 4, wherein the float flow meter 1, the central oxygen supply pipeline interface 2 and the oxygen output pipeline 4 are connected to the regulating valve;

[0031] The flow meter is also provided with a regulator 8, the regulator 8 is provided with an openable outer cover 6, the outer cover 6 is provided with a touch portion at the contact portion with the outer edge of the regulator 8, the outer cover 6 is provided with an audio playing component 61, an audio playing switch 62 and a power supply 63 for providing power to each component;

[0032] The inner wall of the oxygen output pipe 4 is provided with an air flow sensor 3 for sensing gas reflux, which is used to sense the change of gas reflux and control the action of the audio playing switch 62.

[0033] Further optimized, the audio playback switch 62 is connected to the airflow sensor 3, and the power supply 63 is connected in series with the audio playback switch 62 and the audio playback component 61 to form a loop for broadcasting a voice prompt when the audio playback switch 62 is triggered.

[0034] Further optimization, when the outer cover 6 abuts against the regulator 8, the outer cover 6 disconnects the audio playback component 61 and the power supply 63 through the touch portion; when the outer cover 6 is separated from the regulator 8, the touch portion automatically resets to connect the battery to the audio playback component 61, and broadcasts a voice prompt. For example, "Please disconnect the nasal cannula first, then adjust the oxygen flow", "Please pay attention to the adjustment direction", etc. After hearing the prompt tone, the user will not forget to disconnect the nasal cannula first.

[0035] The airflow sensor 3 is a gas flow sensor, which detects the flow velocity or flow change in the oxygen output pipe 4 to sense the reflux change and judge whether the patient is still wearing the nasal cannula. If reflux is detected, the patient is still wearing the nasal cannula, and the airflow sensor 3 sends a signal to the audio playback switch 62. If no reflux is detected, the patient is not wearing the nasal cannula and no signal is sent.

[0036] When the outer cover 6 is opened and the airflow sensor 3 senses backflow, the touch part automatically resets, the audio playback switch 62 receives the signal from the airflow sensor 3, and controls the audio playback component 61 to broadcast a voice prompt; when the outer cover 6 is opened but the airflow sensor 3 does not sense backflow, the touch part automatically resets, the audio playback switch 62 does not receive the signal from the airflow sensor 3, and does not broadcast; when the outer cover 6 is closed and the airflow sensor 3 senses backflow, the touch part disconnects the circuit, the audio playback switch 62 receives the signal from the airflow sensor 3 but the audio playback component 61 does not broadcast.

[0037] It should be noted that the main improvement of this embodiment is that the audio playback component 61, the audio playback switch 62, the power supply 63 and the airflow sensor 3 are combined with the flow meter, which is an improvement on the structure of the flow meter. The existing known technology can be used for the control relationship and control method between the various components.

[0038] Optionally, when the outer cover 6 abuts against the regulator 8, the touch control unit disconnects the audio playing component 61 and the power supply 63 by squeezing or short-circuiting the circuit. There are many specific structures or circuits that can be used, which will not be described in detail here.

[0039] The power source 63 may be a battery or a plug-in power source 63 .

[0040] Furthermore, the outer cover 6 is openably and closably connected to one side of the adjusting machine via a hinge.

[0041] In this embodiment, the resistance part can be replaced by a pressure sensor and then connected to the audio playback switch 62, which is used to sense pressure changes and control the action of the audio playback switch 62. When the pressure of the outer cover 6 is opened and is 0 and the airflow sensor 3 senses the backflow, the audio playback switch 62 receives the airflow sensor 3 and the pressure sensor signals at the same time, and controls the audio playback component 61 to broadcast the voice prompt; when the pressure of the outer cover 6 is opened and is 0 but the airflow sensor 3 does not sense the backflow, the audio playback switch 62 only receives the airflow sensor 3 and does not broadcast.

[0042] In this embodiment, the pressure sensor can be replaced by an infrared sensor.

[0043] Further optimization, the regulator 8 includes an adjusting knob and a chassis with a scale, and a pointer is provided on the adjusting knob. When the adjusting knob is rotated, the pointer coincides with the corresponding scale on the chassis. By rotating the knob to adjust the clearance of the regulating valve, and reflecting it on the corresponding scale on the chassis, the size of the oxygen flow rate can be adjusted more accurately to prevent twisting in the wrong direction.

[0044] Furthermore, the chassis is recessed, and a protrusion 71 for touching is provided at the center of the adjusting knob, so that medical staff can turn the adjusting knob by hand.

[0045] In this embodiment, the adjusting knob contacts the flow gap adjuster 8 in the regulating valve through a screw rod. The screw rod is screwed in by turning the knob to press against the flow gap adjusting plate to expand the gap. The pointer of the knob corresponds to the chassis scale, thereby achieving the effect of adjusting the oxygen intake volume through the chassis scale display.

[0046] Further optimization, the oxygen output pipeline 4 is connected to an oxygen delivery device for oxygen delivery. In this embodiment, the oxygen delivery device is a nasal catheter.

[0047] For further optimization, the scale on the chassis, starting from the 0 scale, is divided into 1 scale every 30°. In this embodiment, the scale is marked with “|” and digitally labeled.

[0048] Further optimization includes a locking device 5 arranged at the lower end of the regulator 8 for locking the outer cover 6 and the regulator 8 together. In this embodiment, the locking device 5 is a lock, and the lower end of the outer cover 6 and the lower end of the regulator 8 are both provided with a positioning ring for the lock ring to pass through, and the regulator 8 and the outer cover 6 are locked together by passing the lock through the positioning ring, and the corresponding key is hung at the nurse station. Or other simple password constructions ensure that only medical staff can open the adjustment.

[0049] In summary, the utility model of an oxygen flow meter control device with a prompt function can provide voice reminders when the oxygen flow is directly adjusted without disconnecting the nasal catheter, thereby preventing such situations from occurring. At the same time, it can ensure that only medical staff with the key can make adjustments, thereby preventing unauthorized personnel from adjusting the oxygen flow meter privately.

[0050] The above shows and describes the main features, basic principles and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will also have various changes and improvements according to actual conditions, and these changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
