Description

Technical Field

[0001] The utility model relates to the technical field of oxygen delivery tubes, in particular to an oxygen delivery tube for respiratory medicine. Background Art

[0002] In the prior art, oxygen delivery tubes are one of the most common medical devices in respiratory medicine. Oxygen delivery tubes are a type of medical device used to deliver oxygen from an oxygen source to a patient's respiratory organs to assist the patient's breathing and improve the body's blood oxygen saturation. Commonly used oxygen delivery tubes include PVC oxygen delivery tubes, PE oxygen delivery tubes, and liquid oxygen tubes.

[0003] In the prior art, oxygen supply tubes are generally connected to each other by simply using interference fit to fix them. Although sealing can be ensured, the connection of the oxygen supply tube is easily dislocated when the oxygen supply tube is pulled. Therefore, an improved oxygen supply tube for respiratory medicine is needed to address this problem. Utility Model Content

[0004] The purpose of the utility model is to provide an oxygen supply tube for respiratory medicine to solve the problems raised in the above background technology.

[0006] Preferably, the limiting plate is made of elastic plastic material, and the limiting plate is obliquely arranged inside the sleeve; when the connecting head is inserted into the connecting port, the limiting ring will move relative to the limiting plate; that is, the limiting ring will move downward along the inclination direction of the limiting plate; thereby, the limiting plate can be squeezed to make the limiting plate bend, so that the limiting plate will not hinder the connecting head from being inserted into the connecting port; on the contrary, when the connecting head wants to be pulled out of the connecting port, the limiting plate will form barbs to prevent the limiting ring from moving upward, thereby preventing the connecting head and the connecting port from separating from each other, thereby effectively preventing the loosening of the connection between the oxygen supply tube and the breathing mask due to pulling.

[0007] Preferably, a plurality of sealing rings are evenly and fixedly arranged on the outer surface of the connector; the sealing rings can improve the sealing performance of the connection between the connector and the connection port.

[0008] Preferably, mounting holes are provided on both sides of the surface of the oxygen mask, through which cable ties can be conveniently passed; and then the oxygen mask is worn and fixed on the patient's mouth and nose.

[0009] Preferably, a fixing ring is fixedly provided on the outer surface of the oxygen tube, an elastic connecting rope is fixedly provided on the upper end of the fixing ring, and an end of the elastic connecting rope close to the sleeve is fixedly connected to the sleeve; Figure 3 As shown, the oxygen tube can be lifted up by one section; at this time, if the lower end of the fixing ring in the oxygen tube is pulled, only when the elastic connecting rope is fully stretched and then the oxygen tube is pulled again, will the connection port and the connector be subjected to pressure; in this way, the elastic connecting rope and the fixing ring can play a certain buffering role, thereby further preventing the connection from loosening.

[0010] Preferably, a soft pad is fixedly provided on the outer surface of the oxygen mask, and the soft pad can improve the wearing comfort of the device.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When the connector is inserted into the connector port, the limiting ring will move relative to the limiting piece, that is, the limiting ring will move downward along the inclination direction of the limiting piece, thereby squeezing the limiting piece to bend it, so that the limiting piece will not hinder the connector from being inserted into the connector port; conversely, when the connector is to be pulled out of the connector port, the limiting piece will form barbs to prevent the limiting ring from moving upward, thereby preventing the connector and the connector port from separating from each other, thereby effectively preventing the oxygen supply tube and the breathing mask from loosening due to pulling.

[0013] 2. When the utility model is used, the oxygen tube can be lifted by a section through the elastic connecting rope and the sleeve; at this time, if the part below the fixing ring in the oxygen tube is pulled, only when the elastic connecting rope is fully stretched and then the oxygen tube is pulled again, the connecting port and the connecting head will be under pressure; in this way, the elastic connecting rope and the fixing ring can play a certain buffering role, thereby further preventing the connection from loosening.
