The oxygen humidification device and the flowmeter of the oxygen humidification device comprise two portions which are the oxygen humidification device and the flowmeter. A groove is arranged in the middle of a flowmeter connecting portion of the oxygen humidification device, a rapid flowmeter connecting portion is of a clamping bead or clamping pin structure, the oxygen humidification device and the flowmeter are rapidly connected in a rapid insertion mode, and the shortcoming that oxygen uptake of patients is delayed due to long installing time caused by traditional threaded connection is overcome. In addition, components of the rapid connecting portion are few, the structure is simple, risks caused by the fact that dust and microorganisms accumulate in the device are avoided, and oxygen uptake safety of the patients is guaranteed.
Description
Technical field
The present invention relates to a kind of oxygen humidifying device and effusion meter thereof that can Fast Installation, belong to medical instruments field.
Background technology
Oxygen uptake is modal clinical treatment means, and for preventing the destruction of dry oxygen to patient respiration mucous membrane, oxygen needs to carry out humidifying before using.Conventional oxygen uptake process is HC oxygen system by oxygen delivery to the gas end before patient's sick bed, gas end connection traffic meter, and effusion meter monitoring flow is also incorporated into oxygen humidifying device by air-flow.Traditional humidification device is to be threaded with the connected mode of effusion meter, and this process has not only increased medical personnel's workload, and incurs loss through delay patient's rescue time.For this reason, medical apparatus and instruments research staff actively seeks a kind of method that can connect fast oxygen humidifying device and effusion meter.CN101362002 discloses a kind of oxygen humidifying device, comprise oxymeter measuring device and oxygen humidification bottle, the two is connected by snap joint, realized quick-detachable socket connection, be convenient to reduce medical personnel's workload, shorten the time of oxygen uptake, solved most of defect of traditional connected mode.But, the critical component quick coupling structure of realizing quick linkage function in this patent is more complicated, it is particularly evident that particularly oxygen enters first parts of effusion meter, first it connect a nut, nut is threaded with a connecting cylinder again, in nut, be provided with piston, piston has stick harness and ring-type plug tail, between plug tail and connecting cylinder, be provided with stage clip etc., during use, stick harness is through the centre bore of seal washer, the hanging support of rear piston tail is on seal washer, and stage clip is pressed on seal washer piston tail part, thereby forms sealing under the effect of stage clip pressure.When the oxygen input on humidification bottle inserts oxymeter measuring device, input will contact piston boit, make to move on piston boit, now piston tail part no longer forms sealing with seal washer, oxygen just from the gap of seal washer and piston tail part by entering into oxygen humidification bottle.Above-mentioned serial parts object is to guarantee the air-tightness of whole device, avoids occurring Leakage Gas, has but ignored the demand of even more important patient safety oxygen uptake.Because parts are more, and spring piston etc. all easily form dead angle, space, cause the accumulation of dust microorganism, during patient's oxygen uptake, may suck pulmonary with air-flow, increase the risk infecting, in addition, because medical oxygen is aseptic oxygen, aseptic gas can be taken away the dust on internal chamber wall in by inner chamber process, antibacterial, microorganism etc., it is a kind of automatically cleaning to pipeline, and the internal structure shutoff of above-mentioned complexity the inner chamber that passes through of oxygen, oxygen each corner of cannot flowing through smoothly, cannot complete the automatically cleaning of pipeline, after long-time use, need device to dismantle sterilization, increased workload and the elaboration of device has been exerted an influence.Meanwhile, assorted many parts have increased production process, improve production cost, and make installation process more loaded down with trivial details, cannot meet the demand of fast and safely oxygen uptake.
Summary of the invention
Through a large amount of test of research staff, discovery can be optimized the structure of traditional quick connector, and the structures such as the plug tail of quick connector fittings body upper end, stick harness, stage clip can be banned completely, can realize identical sealing effectiveness equally, and technique is simple, cost is low, and it is more convenient to use.Owing to having reduced a large amount of parts, quick connecting parts is directly connected with gas distribution channel, make the passage of pedestal and quick connecting parts unimpeded, avoided occurring in pipeline dead angle, eliminate dust and microorganism and piled up probability, oxygen can flow through pipeline smoothly, has improved the self-cleaning ability of channel lumen, thereby reduces patient infection's risk.For better guaranteeing entering of the inner free from dust of effusion meter, antibacterial, foreign body, the present invention is provided with protective cover between effusion meter pedestal and quick connecting parts, forms second protective barrier.In addition, the protective sleeve of effusion meter or pushing sleeve/turn round put to be designed with is convenient to the parts that oxygen uptake pipeline is placed, oxygen uptake pipeline fixing or temporarily place when being convenient to patient and suspending oxygen uptake.
