Description

Oxygen flow meter adapter

technical field

The utility model belongs to the field of medical equipment, in particular to an oxygen flow meter adapter.

Background technique

Oxygen inhaler is an essential equipment for oxygen inhalation therapy of patients, used for observation and regulation of oxygen flow during oxygen delivery, which includes an oxygen flow meter (or flow controller) and a humidification bottle detachably connected to the flow meter. The flow meter is connected with the air source to adjust the flow. The humidification bottle is filled with humidification liquid, and the flow rate of oxygen is adjusted by the flow meter, and after being moistened by the humidification bottle, it can be inhaled by the patient to avoid adverse effects of dry oxygen on the patient.

Among the oxygen inhalers currently used in hospitals, there is a type of humidification bottle that is hung under the flow meter. A dovetail groove is set under the flow meter. The humidification bottle is connected to the dovetail groove of the flow meter through a hanging rod. Connect the tubing to the oxygen outlet of the flow meter. Since the humidification bottle is hung under the flow meter, although it is convenient for medical staff to quickly install it, it is easy to fall off the flow meter, causing the oxygen inhalation tube to fall off from the patient's nasal cavity, which is very unsafe. Moreover, most of the current humidification bottles are disposable oxygen humidification bottles. The humidification bottle is connected to the flow meter through a quick-connect connector. However, for the flow meter with a dovetail groove at the bottom, the quick-connect connector cannot be directly connected to the flow meter. Affects the use of oxygen humidification bottles connected with push-in connectors.

Utility model content

The technical problem to be solved by the utility model is to provide an oxygen flow meter adapter, which is used for the connection between the flow meter with the dovetail groove below and the humidification bottle. The connection is firm and it is convenient to connect with various types of humidification bottles.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

An oxygen flow meter adapter, including an adapter body, the adapter body is composed of an integrally formed upper part, a middle part and a lower part, wherein the upper part is a dovetail platform connected to the dovetail groove on the flow meter, and the dovetail platform and the dovetail groove It adopts transition fit connection, the lower part is a hollow cylinder with connecting thread, which is connected with the humidification bottle or the quick connector of the humidification bottle, and the side of the middle part is equipped with an oxygen inlet pipe plug, which is a hollow tube, and is connected with the lower hollow cylinder. The lumen is connected.

Further, the dovetail platform is a trapezoidal dovetail platform, the top surface of which is trapezoidal, and the top surface and the side surface form a dovetail structure, so that the width of the two ends of the dovetail platform in the length direction is different.

Further, the front end of the oxygen inlet pipe plug is a tapered pipe, the rear end is a straight pipe, and an annular boss is arranged at the junction of the front end and the rear end. The annular boss is a tapered boss, and the tapered surface is transitionally connected with the outer surface of the tapered tube at the front end.

Furthermore, the center line of the oxygen inlet pipe plug is perpendicular to the center line of the dovetail platform.

Owing to having adopted above-mentioned technical scheme, the technical progress that the utility model obtains is:

The utility model utilizes the dovetail platform to connect with the flow meter with the dovetail groove at the lower part, and the dovetail platform is in the shape of a ladder platform, the connection is firm and reliable, easy to install and disassemble, easy to connect with the humidification bottle or the quick connector of the humidification bottle, and the oxygen inlet pipe plug adopts The connecting hose and soft joint are connected to the oxygen outlet of the flow meter, which is convenient for disinfection and use.

Detailed ways

Below in conjunction with embodiment the utility model is described in further detail:

The utility model relates to an oxygen flow meter adapter, which is used for the connection between the humidification bottle and the flow meter, and is specially aimed at the flow meter with a dovetail groove at the lower part, and can be connected with the quick joint of the humidification bottle connected by the quick joint , The connection with the quick connector adopts a threaded fixed connection. The thread can be an internal thread or an external thread, and when the internal thread is used, it can be directly connected with the humidification bottle.

As shown in Figures 1 to 3, the new model includes an adapter body, which consists of an integrally formed upper part 1, middle part 2 and lower part 3, wherein the upper part 1 is a dovetail platform connected to the dovetail groove on the flow meter , the dovetail platform and the dovetail groove are connected by transition fit, the lower part 3 is a hollow cylinder with connecting thread, which is connected with the humidification bottle or the quick connector of the humidification bottle, and the oxygen inlet pipe plug 5 is arranged on the side of the middle part 2, and the oxygen inlet pipe plug 5 is The hollow tube communicates with the inner cavity of the lower 3 hollow cylinders.

In order to ensure hygiene and reduce bacterial contamination, a hose is connected to the oxygen inlet pipe plug 5, and the oxygen outlet plug of the flowmeter is connected to the connection hose through a soft joint, which is convenient for disinfection and use.

In the utility model, the upper dovetail platform is matched with the dovetail groove at the lower part of the flow meter. In order to ensure a tight fit, not easy to fall, and to facilitate installation and disassembly, the dovetail platform is a trapezoidal dovetail platform, that is, its top surface is a trapezoidal surface. , the bottom surface is also trapezoidal, the size of the bottom surface is smaller than the size of the top surface (a reduced version of the top surface with a constant height), so that the top surface and the side surface form a dovetail structure, and the width of the two ends of the dovetail platform in the length direction is different, forming a trapezoidal shape dovetail table.
