Miniature oxygenator with self-locking oxygen bullet connecting component

Abstract

The invention discloses a miniature oxygenator with a self-locking oxygen bullet connecting component, which comprises an oxygen pressure gauge, a body and an oxygen bullet connecting component used for connecting an oxygen bullet. The oxygen pressure gauge is fixed on the top end of the body; the oxygen bullet connecting component is arranged at the bottom end of the body and comprises a connecting cover and a self-locking sheet; the connecting cover is connected to the bottom of the body, and is provided with a self-locking sheet accommodating part; the self-locking sheet is sleeved in the self-locking sheet accommodating part which is provided with a sleeving hole for the oxygen bullet to pass through; the self-locking sheet is provided with a lock hole which is clamped with the oxygenbullet; and a self-locking sheet spring is arranged between one end of the self-locking sheet and the inner wall of the self-locking sheet accommodating part. The miniature oxygenator with the self-locking oxygen bullet connecting component has the advantages of simple and compact structure, low cost, convenient operation, high safety and high reliability.

Description

technical field [0001] The invention mainly relates to the field of calorimetric equipment, in particular to a miniature oxygenator used for calorimetric equipment. Background technique [0002] Existing calorimetric devices (such as calorimeters) all use an oxygen bomb as a heating element, and the oxygen bomb is a part of the oxygen bomb, and can be connected with a micro-oxygenator to realize the oxygen charging function of the oxygen bomb. The existing miniature oxygenator consists of a body, an oxygen pressure gauge and an oxygen warhead connecting assembly used to connect with the oxygen warhead, and completes the oxygenation operation of the oxygen bomb through the ventilation pipeline provided on the body and the gas switching mechanism. At present, a "special surface-contact locking device" is generally used between the oxygenator and the oxygen warhead, which not only serves as a connection, but also prevents the locking device from damaging the oxygen warhead.

Problems solved by technology

In this structure, since the contact surface between the steel ball and the arc-shaped groove of the oxygen warhead is very small, the steel ball is easily squeezed out of the groove on the arc-shaped groove of the oxygen warhead due to the influence of the high-pressure oxygen force in the body during oxygenation. At the same time, with the aggravation of the damage of the oxygen warhead, the steel ball failed to catch the arc-shaped groove of the oxygen warhead during oxygenation, and the oxygenator ejected the oxygen warhead under the action of high-pressure oxygen, which would not only damage the The instrument may also harm the personal safety of the user
