Embodiment Construction

[0020] Such as figure 2 , image 3 Shown, the present invention is the connecting T-type valve on a kind of respirator, and it mainly is made up of T-type valve body 1, valve cover 2, spring 3, valve core 4 and soft gasket 5.

[0021] The T-shaped valve body 1 is composed of a transverse pipe 11 and a longitudinal pipe 12. The longitudinal pipe 12 is vertically connected to the middle section of the transverse pipe 11 and the two are connected. On the wall of the transverse pipe 11 corresponding to the penetration end of the longitudinal pipe 12 , a through hole 13 is opened, and the nozzle at the bottom end of the longitudinal tube 12 can be connected with the medical appliance;

[0022] The valve core 4 is composed of a flange end portion 41 and an extension portion 42 extending downward from the flange end portion 41 . The extension part 42 of the valve core 4 can extend into the lumen of the longitudinal tube 11 . In order to reduce weight, cost, and material, the exte...

Abstract

The invention discloses a connecting T-valve on a respirator, mainly comprising a T-valve body, a valve cover, a spring and a valve core, wherein the T-valve body consists of a horizontal tube and a longitudinal tube; the longitudinal tube is vertically connected in the middle section of the horizontal tube and communicated with the horizontal tube; a through hole is arranged on a horizontal tube wall corresponding to a penetrating end of the longitudinal tube; the valve cover is buckled at the outer end of the through hole of the horizontal tube wall; a valve core body is movably sleeved in a tube cavity of the longitudinal tube; a flange arranged on a penetrating end of the valve core butts against a longitudinal tube mouth and is limited; and both ends of the spring respectively butt against an inner wall surface of the valve cover and the penetrating end of the valve core. As the through hole is arranged on the horizontal tube wall of the T-valve body, the spring and the valve core can be placed in the tube cavity of the longitudinal tube of the T-valve body through the through hole, the valve cover is then covered, and the assembling process is simple.

Description

technical field [0001] The invention relates to a medical device, in particular to a connection T-shaped valve on a respirator. Background technique [0002] In the operation or daily care of critically ill patients, respirators are often used clinically. In the use of the respirator, a T-shaped valve with a trachea socket should be used in conjunction with the T-shaped valve. The T-shaped valve is connected with a breathing tank or spray tank externally and connected with a patient internally. Conventional T-valve (such as figure 1 Shown) is made up of T-shaped valve body 1 ', spring 2 ', spool 3 ', and spring 2 ' and spool 3 ' are movably sleeved in the lumen of the longitudinal pipe 11 ' of T-shaped valve body 1 '. In this conventional T-valve, in order to prevent the valve core 3' from protruding from the lumen of the longitudinal tube 11', the longitudinal tube 11' is designed into two sections, and the upper half is used to cover the spring 2' and the valve core 3' ...
