Description

Technical Field

[0001] The utility model relates to the technical field of oxygen absorption flow meters, in particular to an oxygen absorption flow meter with a dustproof function. Background Art

[0002] An oxygen flow meter is a device used to measure and regulate oxygen flow. It is widely used in oxygen therapy in the medical field. The oxygen flow meter determines the flow rate by measuring the speed at which oxygen passes through. When oxygen flows from the oxygen source into the flow meter, the flow rate is controlled by the flow regulating valve. The flow display device displays the corresponding flow value based on parameters such as the oxygen flow rate and pressure.

[0003] Oxygen flow meters are commonly used in the medical industry and are essential medical equipment in wards and ambulances. As equipment that supplies oxygen to patients, oxygen flow meters must be kept clean to prevent dust, germs, and the like from entering the patient's body through the meter. Chinese Patent Publication No. CN 116059489 A discloses an oxygen flow meter dust cover, which relates to the field of medical equipment technology. The cover comprises a disposable syringe needle cap body that is mounted on an end of an oxygen supply connector and an atomizer connector away from the oxygen flow meter body. The disposable syringe needle cap body is provided with a locking structure that facilitates fixed connection of the disposable syringe needle cap body to the oxygen supply connector and the atomizer connector.

[0004] The above-mentioned dust cover of the oxygen flow meter plays a dust-proof role for the oxygen supply connector and the atomizer connector by putting the disposable syringe needle cap body on the oxygen supply connector and the atomizer connector, reducing the possibility of external dust and dirt entering the oxygen supply connector and the atomizer connector and contaminating the oxygen supply connector and the atomizer connector; however, the needle cap of the disposable syringe, as a part of the disposable syringe, is also a disposable medical product. After the disposable syringe is used, the syringe and the needle cap must be discarded together, and the main function of the needle cap is to protect the needle of the disposable syringe. Its sealing and dust-proof effects are poor, and it is not suitable for the oxygen flow meter, so it cannot be used for dust-proof work of the oxygen flow meter. Utility Model Content

[0005] The purpose of the present utility model is to provide an oxygen flow meter with a dustproof function. Dustproof cover 1 or dustproof cover 2 is provided on the inlet and outlet connectors of the oxygen flow meter. Dustproof cover 1 or dustproof cover 2 can wrap the inlet and outlet connectors to prevent the inlet and outlet connectors from being exposed to the external environment; so as to solve the technical problems raised by the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:
