Description

Technical Field

[0001] The utility model belongs to the technical field of medical consumables, and in particular relates to a clip-type nasal oxygen tube. Background Art

[0002] Nasal oxygen cannula is widely used in hospitals. It is connected to the oxygen supply system for human body to breathe oxygen. The structure of nasal oxygen cannula is very simple, including a main pipe, which is connected to a tee, and the two outlets of the tee are each connected to a branch pipe. The ends of the two branch pipes are connected through an air outlet assembly, and there are two air outlet pipes corresponding to the nose on the air outlet assembly. Generally, the branch pipe has a thin diameter and is directly hung on the ear. The two air outlet pipes of the air outlet assembly can be inserted into the nostrils.

[0003] Since the patient is in an unfixed position on the bed, the air outlet assembly is easy to fall off. At present, there are some anti-falling nasal oxygen cannulas, such as a nasal oxygen cannula with a stable bracket disclosed in CN202221548378.1 and a disposable medical nasal oxygen cannula disclosed in CN202022185833.3, which are either complex in structure or impractical, and the production and assembly are very cumbersome. Utility Model Content

[0004] In view of the above problems, the purpose of the present utility model is to provide a clip-type nasal oxygen cannula, aiming to solve the above technical problems.

[0005] The utility model adopts the following technical solutions:

[0006] The clip-type nasal oxygen cannula comprises a main pipe, the main pipe is connected with a tee, two outlets of the tee are respectively connected with a branch pipe, the ends of the two branch pipes are connected through an air outlet assembly, the air outlet assembly comprises an intermediate pipe, the inner side of the intermediate pipe is connected with two air outlet pipes, the outer side of the intermediate pipe has a pair of protrusions, a support member is provided between the two protrusions, the two air outlet pipes are arranged in an eight-shaped position, and the air outlet pipe comprises an inner oblique portion and a straight portion, and the two have a smooth transition.

[0007] Furthermore, the intermediate tube, the protruding member and the supporting member are an integrally formed structure.

[0008] Furthermore, the intermediate tube is arc-shaped.

[0009] Furthermore, there is a gap on the outer side of the top of the air outlet pipe.

[0010] Furthermore, the support member is bent toward one side of the middle tube.

[0011] Furthermore, a small reinforcement block is provided between the outer side of the root of the air outlet pipe and the middle pipe.

[0012] The beneficial effect of the utility model is that in the structure, the two air outlet pipes of the air outlet assembly are arranged in an eight-shaped shape, and the toughness of the middle pipe itself and the toughness of the supporting member are utilized, and the two air outlet pipes are controlled to open a certain distance by pressing the protruding member, and then placed in the nostrils. After the protruding member is released, the two air outlet pipes are automatically reset, and the parts between the nostrils can be clamped to a certain extent, so as to prevent the air outlet assembly from falling easily. The design structure is simple and the effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural diagram of a clip-on nasal oxygen cannula provided in an embodiment of the utility model;

[0014] Figure 2 It is a structural diagram of the exhaust component. DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0017] like Figure 1-2 As shown, the clip-on nasal oxygen cannula provided in this embodiment includes a main pipe 1, the main pipe 1 is connected to a tee 2, the two outlets of the tee 2 are each connected to a branch pipe 3, the ends of the two branch pipes 3 are connected through an outlet assembly 4, the outlet assembly 4 includes an intermediate pipe 41, the inner side of the intermediate pipe 41 is connected to two outlet pipes 42, the outer side of the intermediate pipe 41 has a pair of protrusions 43, a support member 44 is provided between the two protrusions 43, the two outlet pipes 42 are arranged in an eight-shaped position, the outlet pipe 42 includes an inner oblique portion 421 and a straight portion 422, and the two transitions are smooth. In the figure, the intermediate pipe 41 has connecting sections 46 at both ends, and is plugged with the branch pipe 3 through the connecting section 46.

[0018] In this structure, the middle tube is arc-shaped and made of a rubber hose, which has a certain toughness. In the utility model, there is a pair of protrusions on the outside of the middle tube, which are pressing blocks. The two protrusions can be squeezed inward by two fingers to adjust the top spacing of the two outlet pipes. At the same time, there is a support member between the two protrusions, which is made of elastic material and can be a metal spring. When the protrusion is pressed inward, the support member is deformed, and when it is released, the support returns to its original state.

[0019] As a preferred embodiment, the middle tube 41, the protruding piece 43 and the supporting piece 44 are an integrally formed structure, that is, the entire air outlet assembly is integrally injection molded, the material is consistent, and the various components need to be assembled. In the figure, the supporting piece is also made of plastic, and the supporting piece is bent toward one side of the middle tube. The supporting piece also has a certain toughness. After pressing the protruding piece, the middle part of the supporting piece deforms inward, and then the middle part of the middle tube can be squeezed, so that the two air outlet pipes can be opened. Since this structure uses two air outlet pipes to clamp the position between the nostrils, it does not require a lot of clamping force, and it only needs to be clamped slightly to ensure that the air outlet assembly will not fall off easily.

[0020] In addition, the structure of the air outlet pipe is designed in this structure, which is in an eight-shaped shape. The distance between the tops of the two air outlet pipes is small, and the distance between the roots is large. In this state, a certain clamping force can be provided. At the same time, the top is a straight line, and the contact area with the nostrils is large, which reduces the discomfort. Furthermore, there is a small reinforcement block 45 between the outer side of the root of the air outlet pipe and the middle pipe to ensure that the root position of the air outlet pipe will not be deformed too much.

[0021] Since the outlet pipe of this structure is closer to the inside of the nostril than the conventional outlet pipe, the oxygen outlet airflow is also closer to the inside of the nostril in the reverse direction, which can easily cause discomfort. In this structure, there is a notch 423 on the outside of the top of the outlet pipe 42. By opening the notch, the outlet area can be increased, so that the airflow can be biased to the center of the nostril, and the user experience is good.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
