Detailed Description

The utility model is further described below with reference to the drawings and the detailed description.

As shown in fig. 1 to 6, the oxygen inhaler includes an inhaler body 1 and an output structure 2 connected to the inhaler body 1; the method is characterized in that: the output structure 2 comprises an oxygen distribution block 21, a flow control valve 23 and an output connector 22; the number of the output joints 22 is at least two, and the output joints 22 are connected with the oxygen distribution block 21; the oxygen distribution block 21 is provided with an oxygen cavity 211, a communication hole 212 and a valve mounting hole 213, the oxygen cavity 211 is connected with the inhaler body 1, the communication hole 212 is communicated with the oxygen cavity 211 and the output joint 22, and the valve mounting hole 213 is vertically intersected with the communication hole 212; the flow control valve 23 comprises a valve core 231 and a knob 232, wherein the valve core 231 is installed in the valve mounting hole 213 and matched with the valve mounting hole 213, the valve core 231 is provided with a valve core hole 2311 corresponding to the position of the communication hole 212, and the knob 232 is connected with the valve core 231; oxygen dispensing block 21 has a scale 214 for displaying the opening of flow control valve 23, and knob 232 has an indication arrow 2321 for indicating scale 214.

In addition to the above-described structure, the present utility model also has some other structure of the existing oxygen inhaler, such as an input connector 13 for connecting an oxygen source, a flow rate adjusting structure 11 for adjusting an output flow rate, and a flow rate displaying structure 12 for displaying an output total flow rate. The output connector 22 is also referred to as a pagoda connector in view of the output connector design of the prior art oxygen inhalers.

Taking the central oxygen supply system 6 which is most used by hospitals at present as an example, the input connector 13 is inserted into a socket of the central oxygen supply system 6 for use. Oxygen supplied from the central oxygen supply system 6 is depressurized by the inhaler body 1, then enters the oxygen chamber 211, and is output through the communication hole 212, the valve core hole 2311 and the output connector 22. Because of the at least two output connectors 22, each output connector 22 can be connected with an oxygen inhalation tube, the utility model can be used for at least two persons to inhale oxygen, and can relieve the contradiction between oxygen supply and demand when the oxygen inhalation demand increases sharply.

The utility model is provided with the flow control valve 23, the opening of the flow control valve 23 can be controlled by rotating the knob 232, and the opening of the flow control valve 23 can be known by observing the scale 214 pointed by the indication arrow 2321. The opening degree of the flow control valve 23, that is, the percentage of the area where the spool hole 2311 is not blocked. The scale 214 is particularly preferably 0, 1/4, 1/2, 3/4 and 1 as shown in fig. 4, and represents that the valve body hole 2311 of the flow control valve 23 has an opening area of 0 (closed), 1/4, 1/2, 3/4 of the hole cross-sectional area and is completely opened, respectively. When the gas flow rate is constant, the gas flow rate is calculated by multiplying the flow rate by the flow area. The ratio of the oxygen flow rates outputted from the output connectors 22 is the ratio of the opening degrees of the corresponding flow control valves 23.

Taking two output connectors 22 as an example, the opening degree of one output connector 22 is 1/2, and the opening degree of the other output connector 22 is 1, the ratio of the oxygen flow rates output by the two output connectors 22 is 1:2. The flow regulating structure 11 and the flow displaying structure 12 regulate and display the total oxygen flow outputted by the present utility model, for example, 6L/min. The oxygen flow rates outputted by the two output connectors 22 are calculated to be 2L/min and 4L/min, respectively, according to the ratio of the oxygen flow rates outputted by the two output connectors 22 being 1:2.

It can be seen that the oxygen flow rate output by each output joint 22 is not directly shown in the present utility model, but the oxygen flow rate output by each output joint 22 can be obtained by simple calculation. The flow control means of the present utility model is simple in construction and is significantly lower in cost, volume and weight than the means for providing flow adjustment and display to each output fitting 22.

The oxygen distribution block 21 is preferably arranged in the following manner: the oxygen distribution block 21 is square, the oxygen distribution block 21 is horizontally arranged, the output joint 22 is positioned in front of the oxygen distribution block 21, the graduations 214 are arranged on the upper surface of the oxygen distribution block 21, and the knob 232 is positioned above the oxygen distribution block 21.

The output connector 22 of the present utility model can be provided in many ways in theory, but there is no obvious practical significance in the practice of having too many output connectors 22. The total oxygen flow rate output from the inhaler body 1 is limited, and if the oxygen is inhaled by a large number of people, the total oxygen flow rate is insufficient. The excessive number of output connectors 22 also makes the flow calculation of each output connector 22 cumbersome. The number of output connectors 22 is therefore preferably two in the present utility model.

As mentioned above, the present utility model can supply oxygen to two patients when oxygen inhalation demand increases. In conventional situations, still a patient uses an oxygen inhaler, so that an output connector 22 is not used. In order to avoid that the unused outlet connection 22 is exposed to be contaminated for a long time, it is preferred that the oxygen inhaler comprises a protective cap 3 and a protective cap box 4, the protective cap box 4 being located below the oxygen distribution block 21 and being connected to the oxygen distribution block 21, the protective cap 3 being placed inside the protective cap box 4, the protective cap 3 being capable of being capped on the outlet connection 22.

The output connector 22 may be covered with a protective cover 3 to prevent contamination thereof. When not covered, the protective cover 3 is placed in the protective cover box 4. The protective cover case 4 is a general case that can be opened.

The output connector 22 is used for connecting an oxygen tube, and in particular, as in the prior art, the connector of the oxygen tube is forcibly sleeved on the output connector 22, and the output connector 22 enlarges the connector of the oxygen tube. The oxygen tube is pulled out by force when the oxygen tube is detached. Because the distance between the output joint 22 and the input joint 13 is relatively long, the input joint 13 and the jack of the central oxygen supply system are stressed more and the risk of damage is higher when the oxygen tube is sleeved and pulled out. The oxygen tube can be pulled out by holding the oxygen distribution block 21 in a hand to avoid the problem, but the operation is not easy to be forgotten. For this purpose, the oxygen inhaler preferably comprises a support 5, which support 5 is located behind the oxygen distribution block 21 and is detachably connected to the oxygen distribution block 21.

When the support frame 5 is installed on the wall, the force of the output joint 22 is transmitted to the oxygen distribution block 21, the support frame 5 and the wall, so that the influence on the input joint 13 and the jack of the central oxygen supply system can be avoided, and the oxygen distribution block 21 is not needed to be held by hands.

Because the central oxygen supply system 6 exists, the support frame 5 should avoid the central oxygen supply system 6, so the support frame 5 is preferably U-shaped, and both ends of the support frame 5 are provided with mounting holes. The U-shaped support frame 5 can be mounted on a wall up and down across the central oxygen supply system 6. The mounting holes are used to pass through fasteners to facilitate mounting the support bracket 5 to a wall.

The support frame 5 should be detachably connected to the oxygen distribution block 21, since the oxygen inhaler may be detached from the central oxygen supply system 6 when not in use. The support 5 is detachably connected to the oxygen distribution block 21 in a specific manner as shown in fig. 5, and the oxygen distribution block 21 is provided with fastener holes, wherein fasteners penetrate through the oxygen distribution block 21 and are in threaded connection with the support 5, and the fasteners compress the oxygen distribution block 21.
