Technical Field
The utility model belongs to the technical field of oxygen supply equipment, and particularly provides an oxygen bag and an oxygen therapy device.
Background
An oxygen bag is a bag for holding oxygen and is mainly synthesized from non-toxic and harmless chemical materials. The oxygen bag is convenient to carry and easy to operate, and is often used for home health care and medical unit outgoing first aid.
Clinically, patients often go out, and in order to ensure the safety of the patients, the patients are required to carry an oxygen bag for oxygen inhalation.

Optionally, the control valve, the delivery pump and the flow sensor are all disposed within the housing.
Based on the foregoing description, it can be understood by those skilled in the art that in the foregoing technical solution of the present utility model, by providing the oxygen bag with the first cavity and the second cavity that are not communicated with each other, when the oxygen in the first cavity is exhausted, the patient can determine that the remaining amount of oxygen in the oxygen bag is half, so as to immediately return to the ward, and ensure that the patient can return to the ward before the oxygen in the oxygen bag is exhausted.
Further, the volume of the first cavity is equal to that of the second cavity, and the oxygen bag is provided with the third cavity, so that the third cavity can supply oxygen for a patient in an emergency, and the situation that the patient cannot return to a ward in time due to overlong ward returning time is avoided. Thus, the oxygen bag of the present utility model can ensure that the patient returns to the patient's room before the oxygen in the oxygen bag is completely exhausted.
Further, by enabling the oxygen therapy device to have the first air inlet and the second air inlet, the oxygen therapy device can be connected with the cavities of the two oxygen bags through the first air inlet and the second air inlet respectively. By configuring the control valve for the oxygen therapy device, the oxygen therapy device can selectively flow oxygen flowing in from the first air inlet or the second air inlet to the air outlet through the control valve, thereby ensuring that the oxygen therapy device can deliver oxygen in the oxygen bag cavity to a patient one by one. The conveying pump and the flow sensor are configured for the oxygen therapy device, so that the oxygen therapy device can control the rotating speed of the conveying pump according to the flow sensor detecting the flow of oxygen output by the oxygen therapy device, and the oxygen therapy device can output stable oxygen flow.
Further, by configuring a flow regulator for the oxygen therapy device, the patient can set the flow of oxygen output by the oxygen therapy device through the flow regulator; thereby reducing the rotation speed of the delivery pump when the flow detected by the flow sensor is greater than the flow set by the flow regulator; and when the flow detected by the flow sensor is smaller than the flow set by the flow regulator, increasing the rotating speed of the conveying pump.
Further, by configuring the pressure sensor for the oxygen therapy device, the control valve communicates with one of the first air inlet and the second air inlet that is not in communication when the pressure value detected by the pressure sensor is less than or equal to a preset value. For example, in a state in which the control valve is in communication with the first air inlet, when the pressure value detected by the pressure sensor is less than or equal to a preset value, the control valve is switched to be in communication with the second air inlet and to be out of communication with the first air inlet, thereby causing the delivery pump to deliver oxygen from the second air inlet to the patient.
In summary, the oxygen therapy device of the present utility model is not only capable of automatically delivering a constant flow of oxygen to a patient, but also capable of automatically switching to the next chamber when the chamber of the current oxygen bag is empty of oxygen.
Other advantages of the present utility model will be described in detail hereinafter with reference to the drawings so that those skilled in the art can more clearly understand the improvements object, features and advantages of the present utility model.

The specific meaning of the above terms in the present utility model can be understood by those skilled in the art according to the specific circumstances.
As shown in fig. 1 and 2, in some embodiments of the present utility model, an oxygen bag 100 includes a bag body 110, and a first oxygen catheter 121, a second oxygen catheter 122, and a third oxygen catheter 123 mounted on the bag body 110. The pouch 110 receives and delivers oxygen through the first, second and third oxygen transfer tubes 121, 122 and 123.
As shown in fig. 2, in some embodiments of the present utility model, the pouch 110 defines a first cavity 111, a second cavity 112, and a third cavity 113 that are not in communication with one another.
Further, the first oxygen catheter 121 is fixedly connected with the bag body 110 and communicates with the first cavity 111 to allow oxygen to enter and/or exit the first cavity 111 through the first oxygen catheter 121. The second oxygen therapy tube 122 is fixedly connected to the bag body 110 and communicates with the second cavity 112 to allow oxygen to enter and/or exit the second cavity 112 through the second oxygen therapy tube 122. The third oxygen therapy tube 123 is fixedly connected to the pouch 110 and communicates with the third cavity 113 to allow oxygen to enter and/or exit the third cavity 113 through the third oxygen therapy tube 123.
Optionally, the oxygen bag 100 further includes a first stop valve (not shown in the figure) for controlling the on-off of the first oxygen catheter 121, a second stop valve (not shown in the figure) for controlling the on-off of the second oxygen catheter 122, and a third stop valve (not shown in the figure) for controlling the on-off of the third oxygen catheter 123. The first shut-off valve, the second shut-off valve and the third shut-off valve may be any viable shut-off valve, such as clamps, roller-type flow regulating valves, etc.
Further, in some embodiments of the present utility model, the volume of the first cavity 111 is equal to the volume of the second cavity 112, and the volume of the third cavity 113 is smaller than the volume of the first cavity 111.
Preferably, the volume of the third cavity 113 is not more than one third of the volume of the first cavity 111.
In some embodiments of the present utility model, by having the bag 110 define the first, second, and third cavities 111, 112, 113, the patient can determine whether there is oxygen within the first, second, and third cavities 111, 112, 113 by observing whether the first, second, and third cavities 111, 112, 113 are full or collapsed. Further, the patient is also enabled to determine the remaining condition within the oxygen bag 100 by observing the full and collapsed conditions of the three chambers.
In one scenario, the patient is carrying and using the oxygen bag 100 out, and there is no stopover. When the first cavity 111 collapses, the patient immediately begins to inhale oxygen within the second cavity 112. At the same time, the patient immediately returns to the ward. When the patient returns to the ward, the oxygen in the second chamber 112 has just been inhaled. If insufficient oxygen is present in the second chamber 112 halfway through it, oxygen in the third chamber 113 may be taken in instead.
Thus, in some embodiments of the present utility model, the oxygen bag 100 alerts the patient to timely return to the patient's room and ensures that the patient can timely return to the patient's room by the first, second and third chambers 111, 112, 113 being full and deflated.
In addition, in other embodiments of the present utility model, those skilled in the art may omit the third cavity 113 and the third oxygen catheter 123 as needed, so that the oxygen bag 100 only retains the first cavity 111 and the second cavity 112.
In the present utility model, the oxygen bag 100 may be used alone or in combination with the oxygen therapy device 200 shown in fig. 3 to 5. The oxygen therapy device 200 in some embodiments of the present utility model will be described in detail below with reference to fig. 3-5.

As shown in fig. 3 and 4, the control valve 220, the pressure sensor 230, the delivery pump 240, the flow sensor 250, and the outlet nozzle 260 are sequentially connected in series. The control valve 220 is provided with a first air inlet nozzle 221, a second air inlet nozzle 222 and a third air inlet nozzle 223, the first air inlet nozzle 221 is connected with the first air inlet 201 in a plugging or sealing mode, the second air inlet nozzle 222 is connected with the second air inlet 202 in a plugging or sealing mode, and the third air inlet nozzle 223 is connected with the third air inlet 203 in a plugging or sealing mode.
In addition, in other embodiments of the present utility model, the person skilled in the art may also form the first air inlet 201 on the first air inlet nozzle 221 with the first air inlet 201 exposed on the surface of the housing 210, form the second air inlet 202 on the second air inlet nozzle 222 with the second air inlet 202 exposed on the surface of the housing 210, and form the third air inlet 203 on the third air inlet nozzle 223 with the third air inlet 203 exposed on the surface of the housing 210, as desired.
Further, the inner side of the bottom case 212 is provided with a fixing structure (not shown) in a zigzag shape so that the bottom case 212 is fixed with the control valve 220 by the fixing structure.
In some embodiments of the present utility model, control valve 220 is a three-position, four-way reversing valve having three inlets and one outlet, and control valve 220 is capable of switching to a first state in which first air inlet nozzle 221 communicates with its outlet, a second state in which second air inlet nozzle 222 communicates with its outlet, and a third state in which third air inlet nozzle 223 communicates with its outlet.
In other embodiments of the present utility model, one skilled in the art may also use three parallel shut-off valves instead of the three-position four-way reversing valve, as desired.
As shown in fig. 3-5, in some embodiments of the present utility model, control valve 220, pressure sensor 230, transfer pump 240, flow sensor 250, and outlet nipple 260 are all disposed within housing 210, and outlet nipple 260 is plugged or sealed with outlet 204.
In addition, in other embodiments of the present utility model, one skilled in the art may also form the air outlet 204 on the air outlet nozzle 260 and expose the air outlet 204 on the surface of the housing 210 as desired.
As shown in fig. 3 to 5, a display screen 280 is mounted on the housing 210, and the display screen 280 is used to display the operating state of the oxygen therapy device 200 and oxygen flow data. For example, the display screen 280 may display a pressure value detected by the pressure sensor 230, a flow value detected by the flow sensor 250, a remaining power, etc.
With continued reference to fig. 3-5, a flow regulator 270 is mounted on the housing 210, the flow regulator 270 being configured to regulate the flow of oxygen output by the oxygen therapy device 200 such that the delivery pump 240 adjusts the rotational speed based on the regulated value of the flow regulator 270 and the flow detected by the flow sensor 250.
Further, although not shown, in some embodiments of the utility model, the oxygen therapy device 200 further includes a control module for controlling the operation of the oxygen therapy device 200, a battery for providing electrical energy for the operation of the oxygen therapy device 200, and a power switch. Wherein the control module and the battery are both disposed within the housing 210, and the power switch is mounted on the housing 210.
Still further, the control valve 220, pressure sensor 230, transfer pump 240, flow sensor 250, flow regulator 270, and battery are all electrically connected to the control module.
In some embodiments of the present utility model, the control valve 220 is configured to reduce the rotational speed of the transfer pump 240 when the flow rate detected by the flow sensor 250 is greater than the flow rate set by the flow regulator 270; when the flow rate detected by the flow rate sensor 250 is smaller than the flow rate set by the flow rate regulator 270, the rotational speed of the transfer pump 240 is increased.
Wherein the flow rate set by the flow regulator 270 is manually set by the patient. Specifically, the flow regulator 270 is a resistance or voltage sensor in a dial-up and dial-down form, and the patient sets the oxygen flow by dial-up and dial-down the adjusting button of the flow regulator 270.
In some embodiments of the present utility model, the control valve 220 is further configured to switch the control valve 220 to the next state when the pressure value detected by the pressure sensor 230 is less than or equal to a preset value.
For example, in a state in which the control valve 220 is in communication with the first air inlet 201, when the pressure value detected by the pressure sensor 230 is less than or equal to a preset value, the control valve 220 is shifted to a state in which it is in communication with the second air inlet 202 and is out of communication with the first air inlet 201, thereby causing the delivery pump 240 to deliver oxygen from the second air inlet 202 to the patient.
The preset value corresponding to the pressure sensor 230 is not greater than 130Pa, for example, it may be 130Pa. When the value detected by the pressure sensor 230 reaches the preset value, it indicates that the oxygen in the current chamber has been evacuated.
In some embodiments of the present utility model, the control valve 220 is further configured to stop the rotation of the transfer pump 240 when the pressure value detected by the pressure sensor 230 is less than or equal to a preset value in a state where the control valve 220 is connected to the third air inlet 203.
The method of using the oxygen therapy device 200 of the present utility model will now be described in detail with reference to fig. 6 in conjunction with the oxygen bag 100 described above.
As shown in fig. 6, first, the first oxygen catheter 121, the second oxygen catheter 122, and the third oxygen catheter 123 of the oxygen bag 100 are connected to the first air inlet 201, the second air inlet 202, and the third air inlet 203 of the oxygen therapy device 200, respectively, and the nasal oxygen catheter 300 is connected to the air outlet 204 of the oxygen therapy device 200. The patient then wears the nasal oxygen cannula 300 over the nose to inhale oxygen. The flow regulator 270 is then adjusted so that the oxygen therapy device 200 provides a corresponding flow of oxygen to the patient.
In operation of the oxygen therapy device 200, oxygen is withdrawn in the order of the first chamber 111, the second chamber 112, and the third chamber 113. When the oxygen in the first chamber 111 is evacuated, the pressure value detected by the pressure sensor 230 is less than or equal to a preset value, the control valve 220 is switched to the second state, and the oxygen in the second chamber 112 starts to be extracted. When the oxygen in the second chamber 112 is evacuated, the pressure value detected by the pressure sensor 230 is less than or equal to a preset value, the control valve 220 is switched to the third state, and the extraction of the oxygen in the third chamber 113 is started. When the oxygen in the third chamber 113 is evacuated, the pressure value detected by the pressure sensor 230 is less than or equal to a preset value, and the delivery pump 240 stops operating.
Based on the foregoing description, it can be appreciated by those skilled in the art that in some embodiments of the present utility model, by having the oxygen bag 100 have the first cavity 111 and the second cavity 112 not in communication with each other, the patient can determine that half of the remaining amount of oxygen in the oxygen bag 100 is left when the oxygen in the first cavity 111 is exhausted, thereby immediately returning to the ward, ensuring that the patient can return to the ward before the oxygen in the oxygen bag 100 is exhausted.
Further, by causing the oxygen therapy device 200 to extract oxygen from the oxygen bag 100, the oxygen therapy device 200 can sequentially deliver oxygen from the plurality of chambers of the oxygen bag 100 to the patient. Specifically, by configuring the delivery pump 240 and the flow sensor 250 for the oxygen therapy device 200, the oxygen therapy device 200 can control the rotational speed of the delivery pump 240 according to the flow sensor 250 detecting the flow rate of oxygen output by the oxygen therapy device 200, thereby enabling the oxygen therapy device 200 to output a stable flow rate of oxygen. By configuring the pressure sensor 230 for the oxygen therapy device 200, the control valve 220 is enabled to switch to the next state when the pressure value detected by the pressure sensor 230 is less than or equal to a preset value.
In the present utility model, the oxygen therapy device 200 may be used not only with the oxygen bag 100 described above, but also with a plurality of common oxygen bags. When the oxygen therapy device 200 is used with a plurality of common oxygen bags, the first air inlet 201, the second air inlet 202, and the third air inlet 203 of the oxygen therapy device 200 are each connected to one oxygen bag.
Furthermore, in other embodiments of the present utility model, one skilled in the art may also increase or decrease the number of air inlets on the oxygen therapy device 200 as desired, for example, to leave the oxygen therapy device 200 with only the first air inlet 201 and the second air inlet 202.
In addition, in other embodiments of the present utility model, one skilled in the art may omit the pressure sensor 230 as needed, and allow the patient to manually observe the presence or absence of oxygen in the oxygen bag 100. Alternatively, one skilled in the art may also omit the provision of flow sensor 250 and have oxygen delivery device 200 deliver oxygen at a single flow rate, as desired.
Thus far, the technical solution of the present utility model has been described in connection with the foregoing embodiments, but it will be readily understood by those skilled in the art that the scope of the present utility model is not limited to only these specific embodiments. The technical solutions in the above embodiments can be split and combined by those skilled in the art without departing from the technical principles of the present utility model, and equivalent changes or substitutions can be made to related technical features, so any changes, equivalent substitutions, improvements, etc. made within the technical principles and/or technical concepts of the present utility model will fall within the protection scope of the present utility model.
