Description

Technical Field

[0001] The utility model relates to the technical field of three-way joints for high-pressure oxygen delivery tubes, in particular to a three-way joint for high-pressure oxygen delivery tubes. Background Technique

[0002] Oxygen delivery is a method of inhaling oxygen by inserting special bilateral nasal catheters into both nostrils. Its main function is to increase the arterial oxygen partial pressure, improve the body's oxygen supply, and reduce the increased respiratory and circulatory burdens due to compensatory hypoxia. The causes of hypoxia caused by different diseases are different, and the oxygen delivery effects are also different. For those with impaired gas exchange function due to lung tissue lesions, resulting in oxygen absorption disorders or insufficient ventilation, the oxygen delivery effect is significant; for those with oxygen transport disorders caused by circulatory insufficiency or anemia, oxygen delivery has a certain effect, but the hypoxia problem cannot be fundamentally solved.

[0003] Existing critically ill patients usually need oxygen delivery. When there are many patients in need of oxygen delivery, a three-way tube is used to split the oxygen output from the oxygen cylinder. Since the oxygen delivery tube connected to the patient is connected to the three-way tube in a sleeved manner, if the patient pulls it repeatedly or the medical staff accidentally touches it, it may cause the oxygen delivery tube to gradually separate from the three-way tube. Therefore, when the oxygen delivery tube is separated from the three-way tube, it will pose a threat to the patient. For this reason, we provide a three-way joint for high-pressure oxygen delivery tubes. Content of the Utility Model

[0025] Embodiment 1

[0026] As Figures 1 - 4As shown in the figure, the present utility model provides a technical solution: a three-way joint for a high-pressure oxygen delivery pipe, including: a main body mechanism 1, the main body mechanism 1 includes a three-way pipe 11, an oxygen delivery pipe body 12 is sleeved on the outer surface of the three-way pipe 11, the oxygen delivery pipe body 12 is slidably connected to the three-way pipe 11, a first groove 13 is opened on the three-way pipe 11, a second groove 14 is opened on the oxygen delivery pipe body 12, a fixing mechanism 2 is provided on one side surface of the three-way pipe 11, the fixing mechanism 2 includes a first elastic clamping block 21, a second elastic clamping block 22 is provided on one side surface of the first elastic clamping block 21, a first semi-circular block 23 is fixedly connected to the inner walls of the first elastic clamping block 21 and the second elastic clamping block 22, a second semi-circular block 24 is fixedly connected to the inner walls of the first elastic clamping block 21 and the second elastic clamping block 22, a connecting column 25 is fixedly connected to the outer surface of the second elastic clamping block 22, a tapered block 26 is fixedly connected to one end of the connecting column 25, a clamping hole 27 that fits the tapered block 26 is opened on the first elastic clamping block 21, a rotating shaft 28 is provided in a rectangular groove opened on the first elastic clamping block 21, the number of the rotating shafts 28 is two, the rotating shafts 28 are fixedly connected to the first elastic clamping block 21, a rotating sleeve block 29 is sleeved on the outer surface of the rotating shaft 28, the rotating sleeve block 29 is rotatably connected to the rotating shaft 28, the rotating sleeve block 29 is fixedly connected to the second elastic clamping block 22, a separating block 201 is provided at one end of the first elastic clamping block 21 and the second elastic clamping block 22, and the separating block 201 is fixedly connected to the first elastic clamping block 21 and the second elastic clamping block 22.

[0027] In this embodiment, by setting the fixing mechanism 2, the three-way pipe 11 and the oxygen delivery pipe body 12 can be fixed simultaneously, so that the three-way pipe 11 and the oxygen delivery pipe body 12 will not be separated due to continuous pulling and accidental touch. In addition, the first groove 13 opened on the three-way pipe 11 can be used for placing the second semi-circular block 24, and the second groove 14 opened on the oxygen delivery pipe body 12 can be used for placing the first semi-circular block 23. Thus, under the action of the first semi-circular block 23 and the second semi-circular block 24, the first elastic clamping block 21 and the second elastic clamping block 22 can fix the three-way pipe 11 and the oxygen delivery pipe body 12 by means of clamping. By setting the connecting column 25 and the tapered block 26, and the diameter of the tapered block 26 is slightly larger than that of the clamping hole 27, the tapered block 26 can enter the clamping hole 27 by extrusion. Therefore, under the action of the tapered block 26, the first elastic clamping block 21 and the second elastic clamping block 22 will not be easily separated after being fitted together. By setting the separating block 201, it is convenient for medical staff to separate the first elastic clamping block 21 and the second elastic clamping block 22.

[0028] Embodiment 2

[0029] As Figures 1 - 4As shown in the figure, an auxiliary mechanism 3 is provided on the outer surface of the tee pipe 11. The auxiliary mechanism 3 includes a sliding ring 31 sleeved on the outer surface of the tee pipe 11. The sliding ring 31 is slidably connected to the tee pipe 11. A control block 32 is provided on the outer surface of the sliding ring 31. The control block 32 is fixedly connected to the sliding ring 31. An extrusion column 33 is provided on one side surface of the sliding ring 31. The extrusion column 33 is fixedly connected to the control block 32.

[0030] In this embodiment, by providing the auxiliary mechanism 3, it is convenient for medical staff to separate the tee pipe 11 and the oxygen delivery pipe body 12, avoiding frictional damage to the fingers of medical staff caused by forcibly pulling the oxygen delivery pipe body 12. By providing the control block 32, medical staff can more conveniently control the sliding ring 31. The provision of the extrusion column 33 can extrude and slide the oxygen delivery pipe body 12, making it easier for the oxygen delivery pipe body 12 to be separated from the tee pipe 11.

[0031] Working principle:

[0032] As Figures 1 - 4As shown in the figure, when the present utility model is in use and oxygen needs to be supplied to a patient, the oxygen delivery tube body 12 can be sleeved with the three-way tube 11. The sleeved position of the oxygen delivery tube body 12 is appropriate. Then, the first elastic clamping block 21 is placed on the bottom side of the oxygen delivery tube body 12, and the first semi-circular block 23 fixedly connected to the first elastic clamping block 21 is placed in the second groove 14 opened on the oxygen delivery tube body 12. At the same time, the second semi-circular block 24 fixedly connected to the first elastic clamping block 21 is placed in the first groove 13 opened on the three-way tube 11. Then, the second elastic clamping block 22 is flipped, and the second elastic clamping block 22 will drive the rotating sleeve block 29 to rotate around the rotating shaft 28 until the connecting column 25 and the conical block 26 fixedly connected to the second elastic clamping block 22 gradually approach the clamping hole 27 opened on the first elastic clamping block 21, and the connecting column 25 and the conical block 26 are pressed hard, so that the conical block 26 is squeezed into the clamping hole 27. At this time, the connecting column 25 will be completely placed in the clamping hole 27, and under the action of the conical block 26, the first elastic clamping block 21 and the second elastic clamping block 22 are kept firmly attached. At the same time, when the second elastic clamping block 22 is attached to the first elastic clamping block 21, the first semi-circular block 23 and the second semi-circular block 24 fixedly connected to the second elastic clamping block 22 will respectively enter the second groove 14 and the first groove 13. At this time, the fixation of the oxygen delivery tube body 12 and the three-way tube 11 is completed. Furthermore, the three-way tube 11 and the oxygen delivery tube body 12 will not be separated due to continuous pulling from the outside. If it is necessary to separate the oxygen delivery tube body 12 and the three-way tube 11, two separation blocks 201 can be pulled simultaneously to release the connection between the first elastic clamping block 21 and the second elastic clamping block 22 by using the separation blocks 201. Finally, the control block 32 is used to drive the sliding ring 31 to slide, and the sliding ring 31 will drive the extrusion column 33 to extrude the edge part of the oxygen delivery tube body 12, so that the oxygen delivery tube body 12 and the three-way tube 11 are not too closely attached, and then the oxygen delivery tube body 12 is extruded to complete its separation from the three-way tube 11.

[0033] The above description is only a preferred embodiment of the present utility model, and it is not a limitation of the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
