Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a flow meter that displays the available time of residual oxygen. Background Art

[0002] Oxygen flowmeter is a commonly used instrument in the process of oxygen inhalation in the medical industry. Oxygen inhalation is a clinical operation to provide oxygen to patients who need oxygen support. In order to effectively understand the remaining oxygen balance in the oxygen cylinder at any time, an oxygen flowmeter is generally used to measure the oxygen amount, or the gas pressure of the oxygen cylinder is measured by an oxygen pressure gauge, and the oxygen balance is calculated by the oxygen supply time. In the actual use process of medical staff, the relationship between pressure data and time and the remaining oxygen amount is calculated in advance, and then a comparison table of oxygen pressure, balance, oxygen consumption and time is prepared, which can intuitively understand the remaining oxygen balance in the oxygen cylinder, which is simple and direct. In order to improve the accuracy of the calculation of the oxygen balance, the utility model provides a flow meter that displays the available time of the oxygen balance.

[0003] In the prior art, there is an oxygen flowmeter with publication number CN217724271U, which includes a meter joint, on which an oxygen inlet pipe, an oxygen outlet pipe, a flow display tube, an oxygen outlet connected to the humidification bottle, and a switch are provided. An inner tube is provided in the flow display tube, and the inner tube and the top of the flow display tube form a closed space, and a float is provided at the bottom of the inner tube. The oxygen inlet pipe is connected to the inner tube, and the oxygen inlet pipe is connected to the oxygen outlet pipe or the oxygen outlet through the switch. A flow regulating switch is provided on the oxygen inlet pipe, and the end of the oxygen outlet pipe has a first thread, and the flow regulating switch has a scale regulating dial. Through the first thread, the oxygen inhalation pipeline can be effectively prevented from falling out during the patient's oxygen inhalation process. The flow regulating switch has a scale regulating dial. Through the flow regulating switch, the nursing staff can quickly and intuitively observe the oxygen flow when the oxygen cylinder of the patient is placed flat when transporting the patient, which is convenient for the nursing staff to operate.

[0004] The above patent proposes that the existing oxygen flowmeter is usually used by nursing staff to quickly and intuitively observe the oxygen flow rate when the oxygen cylinder is placed flat during the transfer of patients, or in the actual operation of the existing oxygen cylinder, a comparison table of oxygen pressure, remainder, oxygen consumption and usage time is used to find the oxygen remainder on the comparison table through oxygen pressure and oxygen usage time to understand the remaining oxygen remainder in the oxygen cylinder. However, this method uses an estimation method with relatively poor accuracy. However, during use, the oxygen discharge can only be turned on and off, and the flow rate cannot be manually adjusted, thereby limiting the scope of use of the device and reducing the practicality of the device. It is also inconvenient to quickly fix and disassemble the oxygen flowmeter, resulting in complicated and troublesome steps, which makes disassembly time-consuming and labor-intensive. Therefore, the utility model provides a flow meter that displays the available time of the oxygen remainder. Utility Model Content
