Description

Oxygen mask Technical Field The invention relates to the technical field of masks, in particular to an oxygen mask. Background Medical oxygen masks are commonly used oxygen supply devices in clinic, and form a relatively airtight cavity by being buckled on the mouth and nose of a patient so as to ensure the transportation of effective oxygen. Under the conventional condition, the design and wearing of the oxygen absorber can better meet the oxygen absorption requirements of most patients. However, for patients requiring a simultaneous retention of a gastric tube (e.g., nasogastric tube, gastrointestinal decompression tube, etc.), the gastric tube is typically passed clinically through a fit gap between the patient's face and the mask rim. The stomach tube is easy to bend and deform due to the extrusion of the mask, the drainage of the stomach tube is affected, and local skin compression, pain and even damage can be easily caused. Secondly, the original sealing environment between the mask and the face is destroyed by the gastric tube, so that oxygen leaks from the gap, and the oxygen therapy effect is affected. Thus, there is a great clinical need for an oxygen mask that is compatible with gastric tubes, ensures tightness, and is easy to care for. Disclosure of Invention First, the technical problem to be solved In view of the above-described drawbacks and deficiencies of the prior art, the present invention provides an oxygen mask that is compatible with gastric tubes, ensures tightness, and facilitates care. (II) technical scheme In order to achieve the above purpose, the main technical scheme adopted by the invention comprises the following steps: the embodiment of the invention provides an oxygen mask, which comprises a mask body, a connecting seat and a locking piece: the mask body is provided with a stomach tube socket, the connecting seat can be sleeved outside the stomach tube, and the first end of the connecting seat can be radially compressed and contracted or reset and expanded; When the mask body is worn, the connecting seat sleeved outside the stomach tube is inserted into the stomach tube socket, the locking piece is connected with and radially extrudes the first end of the connecting seat, the first end of the connecting seat radially contracts to clamp the stomach tube, and the locking piece and the second end of the connecting seat respectively clamp the two ends of the stomach tube socket; when the mask body is taken down, the locking piece is detached, the first end of the connecting seat is reset and expanded to loosen the stomach tube, and the mask body can be separated from the stomach tube. According to the invention, the connecting seat and the locking piece are ring bodies, the connecting seat can be sleeved outside the stomach tube, and the locking piece can be sleeved and radially extruded to the first end of the connecting seat; The connecting seat and the locking piece are respectively provided with annular sealing surfaces which can seal and clamp the two ends of the stomach tube socket. According to the invention, the locking piece is in threaded connection with the first end of the connecting seat; The first end of the connecting seat is provided with a plurality of claw bodies which are arranged at intervals along the circumferential direction, and the outer walls of the claw bodies and the inner wall of the locking piece are wedge-shaped surfaces; when the locking piece is sleeved and connected with the first end of the connecting seat in a threaded mode, the locking piece radially extrudes the claw bodies, and the claw bodies are radially compressed and clamped on the periphery of the stomach tube. According to the invention, the connecting seat comprises a first sleeve arranged coaxially and an annular base extending outwards along the radial direction of the first sleeve; The first end of the first sleeve forms the first end of the connecting seat, the end part of the first end of the first sleeve is provided with a plurality of claw bodies at intervals along the circumferential direction, the outer wall of the first end of the first sleeve is provided with a threaded surface, the annular base is positioned at the second end of the connecting seat, and the end surface of the annular base is an annular sealing surface for sealing and clamping the end surface of the gastric tube socket. According to the invention, the first sealing ring is arranged on the inner periphery of the first sleeve, and the second sealing ring is arranged at one end of the annular base, which is propped against the gastric tube socket. According to the invention, the stomach tube socket is in a cylindrical shape protruding out of the mask body, and the outer end surface of the stomach tube socket extends axially from the inner periphery to form a limiting ring; the locking piece comprises a second sleeve and a third sleeve which are coaxially arranged, wherein the inner diameter of the third sleev
