Detailed Description
(example 1)
The embodiment is a medical oxygen inhalation mask, which is shown in fig. 1 to 12, and comprises a mask body 1, a connecting cylinder 2 fixedly arranged on the mask body and a nasal tube 3 arranged on the connecting cylinder.
The mask body is substantially bowl-shaped for covering the mouth and nose of a patient.
The basic shape of the connecting cylinder is hollow cylinder, the mask body is provided with a hole, and the outer wall of the connecting cylinder is sealed and fixed in the hole of the mask body through adhesive.
A shaking sliding cavity 21 is arranged in the connecting cylinder 2, and the wall body of the connecting cylinder is provided with an oxygen inlet hole 22, a nasal tube inserting hole 23, a shaking hole 24 and an exhaust hole 25; the number of the exhaust holes is two, and the exhaust holes are respectively positioned at two sides of the rocking hole along the axial direction of the connecting cylinder; the oxygen inlet hole is positioned between the rocking hole and the nasal cannula inserting hole. In this embodiment, a convex tube 26 sleeved with the external oxygen supply tube is further arranged on the outer wall of the connecting cylinder, and the convex tube is communicated with the shaking sliding cavity through the oxygen inlet hole.
The nasal tube 3 includes a tube shaft portion 31, a stopper tube portion 32, and a handle portion 33; the tube shaft part is tubular in basic shape, a tube cavity 34 is arranged in the tube shaft part, and a ventilation notch 35 and an air delivery hole 36 are arranged on the tube wall of the tube shaft part; the outer wall of the pipe shaft part is provided with an air conveying groove 37 extending towards the direction of the pipe plugging part; the plug pipe part and the rocking handle part are respectively positioned at two side ends of the pipe shaft part, and the inner cavity of the plug pipe part is communicated with the pipe cavity of the pipe shaft part. The number of the vent notches is two, and the vent notches are arranged at the end edges of two sides of the pipe shaft part along the axis direction; the number of the air delivery holes is one, and the air delivery holes and the vent notches are located on both sides of the handle portion in the circumferential direction along the pipe shaft portion. In this embodiment, the plug portion has an L-shaped outer shape.
The tube shaft part of the nasal tube is inserted into the rocking sliding cavity of the connecting cylinder from the nasal tube inserting hole, the rocking handle part passes through the rocking hole of the connecting cylinder and extends out of the mask body, and the tube plugging part is positioned in the mask body. The rocking handle part can drive the pipe shaft part to rotate in the rocking slide cavity of the coupling cylinder in a reciprocating mode for a certain angle.
When the nasal tube is rocked to the bottom in one direction, namely the rocking handle part is abutted against one end of the rocking hole, the air delivery groove 37 is communicated with the oxygen inlet hole 22, the air delivery hole 36 is communicated with the rocking hole 24, and the ventilation notch 35 and the exhaust hole 25 are separated by the wall body of the connecting cylinder; when the nasal tube is rocked to the bottom in the other direction, namely the rocker part is abutted against the other end of the rocker hole, the air transmission groove 37 is isolated from the oxygen inlet hole 22, the air transmission hole 36 is isolated from the rocker hole 24, the air transmission hole 36 is communicated with the oxygen inlet hole 22, and the ventilation notch 35 is communicated with a corresponding exhaust hole 25.
When the oxygen mask is used as the oxygen mask, as shown in fig. 1 to 3, the rocking handle part 33 abuts against the upper end of the rocking hole 24, most of the ventilation notch 35 is positioned in the nasal tube insertion hole 23, and the wall body of the nasal tube shaft part 31 separates the tube cavity 34 of the tube shaft part and the vent hole 25 of the connecting cylinder, so that the vent hole 25 is not communicated with the tube cavity 34 of the tube shaft part; the oxygen inlet hole 22 is opposite to the air transmission groove 37 of the nasal tube, namely the oxygen inlet hole is communicated with the air transmission groove; at the moment, oxygen enters the mask body through the oxygen inlet hole 22 and the air transmission groove 37 in sequence, waste gas exhaled by a patient enters the tube cavity 34 of the nasal tube shaft part through the inner cavity of the plug tube part and the ventilation notch, and is then discharged through the air transmission hole 36 of the nasal tube shaft part and the rocking hole 24 of the connecting cylinder in sequence.
When the nasal cannula is used as an oxygen inhalation nasal cannula, the state is obtained by swinging the handle part in fig. 3 along the clockwise direction as shown in fig. 10 to 12, and the nasal cannula is inserted into the nose of a patient; at the moment, the handle part 33 abuts against the lower end of the rocking hole 24, and each ventilation notch 35 rotates clockwise along with the handle part by a certain angle, so that the ventilation notches are communicated with one corresponding exhaust hole 25 on the wall body of the connecting cylinder; in addition, because the gas transmission groove 37 and the gas transmission hole 36 also rotate a certain angle along with the rocking handle part, the oxygen inlet hole 22 is not communicated with the gas transmission groove 37 any more, but is communicated with the gas transmission hole 36; at the moment, oxygen mainly enters the tube cavity 34 of the nasal tube shaft part through the oxygen inlet hole 22 and then enters the inner cavity of the nasal tube plug part, a small part of oxygen entering the tube cavity 34 of the tube shaft part enters the mask body through the part of the vent notch 35 remained in the nasal tube plug-in hole 23, even a small part of oxygen entering the tube cavity is discharged through the vent hole 25, but the hole diameter of the vent hole is far smaller than that of the plug part, so that the waste oxygen is less and negligible; the exhaust gas exhaled by the patient enters the tube cavity 34 of the tube shaft part through the plug tube part and the part of the ventilation notch remained in the nasal tube insertion hole 23 and is exhausted through the exhaust hole 25.
The advantages of this embodiment are: the nursing staff can switch between the oxygen inhalation nasal tube and the oxygen inhalation mask by shaking the handle part of the nasal tube, so that the embodiment has both functions.
