Description

Technical Field

[0001] The utility model relates to the field of medical supplies, in particular to an oxygen supply nasal catheter with an anti-drop structure. Background Art

[0002] Nasal cannula oxygen administration is to insert an oxygen nasal cannula into the nostrils. The nasal cannula usually consists of two, which supply oxygen to the human body through the nasal cavity. The oxygen nasal cannula usually consists of a nasal cannula and an oxygen tube. One end of the oxygen tube is connected to the nasal cannula, and the other end of the oxygen tube is connected to an oxygen cylinder or a central oxygen supply device. When administering oxygen, the nasal cannula is inserted into the nostrils to supply oxygen to the patient.

[0003] During the use of existing oxygen nasal cannulas, they are usually tied to the head with a strap to fix the oxygen nasal cannula. In this way, when the patient's head lies flat, it will be squeezed between the pillow, and the strap will exert pressure on the head, causing discomfort. At the same time, when the patient turns over, it is easy to cause the strap to be misplaced, which will cause the oxygen nasal cannula to detach from the nasal cavity. During installation, medical staff are required to lift the patient's head or the patient needs to lift it by himself, which is quite troublesome. For this reason, we propose an oxygen nasal cannula with an anti-detachment structure. Utility Model Content

[0004] In view of the above problems, the utility model provides an oxygen supply nasal cannula with an anti-detachment structure, which has the advantage of solving the above problems.

[0005] The technical solution of the utility model is:

[0006] A nasal cannula for oxygen supply with an anti-slip structure comprises a mounting block, both ends of the mounting block are provided with fixed through grooves, the inner side of the fixed through grooves is movably connected with an elastic band, the end of the elastic band away from the mounting block is fixedly connected with a connecting hanging ring, the interior of the mounting block is fixedly connected with a connecting tube, one end of the connecting tube is fixedly connected with a rubber plug, the other end of the connecting tube is fixedly connected with an oxygen supply tube, the other end of the oxygen supply tube is fixedly connected with a connecting plug, both side edges of the elastic band are fixedly connected with bonding reinforcement mechanisms, the bonding reinforcement mechanisms comprise bonding blocks fixedly connected to the edges of the elastic band, and the surface of the bonding blocks is bonded with protective paper.

[0007] The working principle of the above technical solution is as follows:

[0008] When wearing it, the elastic band can be directly pulled so that the connecting ring can be hung on the patient's ear for fixation, so that it can be worn stably to avoid dislocation caused by turning over or rubbing, which may lead to falling off; it is convenient to insert the rubber plug into the nasal cavity and squeeze it against the nasal cavity, so as to increase the friction between them, so that it can be firmly and stably used in the nasal cavity and continuously supply oxygen to the patient; when wearing it, it is convenient to connect it with the external oxygen tube through the connecting plug, and the adhesive reinforcement mechanism can be adhered to the patient's face for reinforcement, so that the whole can be in a state of single use by one person to avoid infection; it is convenient to tear off the protective paper from the surface of the adhesive block, so that the adhesive surface of the adhesive block can be attached to the patient's face for connection and fixation.

[0009] In a further technical solution, an easy-to-tear protrusion is provided at one end of the protective paper away from the elastic band.

[0010] By pulling the easy-to-tear protrusion, the protective paper can be more conveniently torn off from the surface of the bonding block, so that the bonding block can be bonded for use, and the operation is convenient.

[0011] The beneficial effects of the utility model are:

[0012] 1. The elastic band and the connecting ring are provided, so that the connecting ring can be put on the outside of the patient's ear during use, so as to fix the installation block. At the same time, the overall connection can be reinforced under the action of the bonding reinforcement mechanism, so that the whole can be used more stably;

[0013] 2. The rubber plug can be stably inserted into the patient's nasal cavity, and mutual friction can be provided between the rubber plug and the inner side of the patient's nasal cavity, so that the rubber plug is not easy to fall off from the patient's nasal cavity, so that the whole can be used more stably and conveniently.

[0019] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0020] Example:

[0021] like Figure 1-Figure 3 As shown, an oxygen supply nasal cannula with an anti-slip structure comprises a mounting block 1, both ends of the mounting block 1 are provided with fixed through grooves 2, the inner side of the fixed through grooves 2 is movably connected with an elastic band 3, one end of the elastic band 3 away from the mounting block 1 is fixedly connected with a connecting hanging ring 4, a connecting tube 5 is fixedly connected inside the mounting block 1, one end of the connecting tube 5 is fixedly connected with a rubber plug 6, the other end of the connecting tube 5 is fixedly connected with an oxygen supply tube 7, the other end of the oxygen supply tube 7 is fixedly connected with a connecting plug 8, and both side edges of the elastic band 3 are fixedly connected with an adhesive reinforcement mechanism 9, so that when wearing, the connecting plug 8 can be plugged into an external oxygen tube, and the oxygen supply tube 7 can be connected to the oxygen supply tube 7. The adhesive reinforcement mechanism 9 can be adhered to the patient's face for reinforcement, so that the whole can be in a single-person single-use state to avoid infection. The adhesive reinforcement mechanism 9 includes an adhesive block 10 fixedly connected to the edge of the elastic band 3, and a protective paper 11 is adhered to the surface of the adhesive block 10, which is convenient for tearing the protective paper 11 from the surface of the adhesive block 10, so that the adhesive surface of the adhesive block 10 can be attached to the patient's face for connection and fixation. An easy-to-tear protrusion 12 is provided at one end of the protective paper 11 away from the elastic band 3. By pulling the easy-to-tear protrusion 12, the protective paper 11 can be more conveniently torn off from the surface of the adhesive block 10, thereby bonding the adhesive block 10 for use, and the operation is convenient.

[0022] The working principle of the above technical solution is as follows:

[0023] When in use, the connecting plug 8 is plugged into the external oxygen tube, and then the rubber plug 6 is inserted into the patient's nasal cavity, and then the elastic band 3 is pulled so that the connecting ring 4 can be hung on the outside of the patient's ear, so that the whole can be quickly installed and used, and finally the easy-to-tear protrusion 12 can be pulled to drive the protective paper 11 to move, so that the protective paper 11 can be detached from the outside of the surface of the adhesive block 10, and the adhesive block 10 is attached to the patient's face, so that the whole can be fixed. At the same time, there is mutual friction between the rubber plug 6 and the inner side of the patient's nasal cavity, so that the rubber plug 6 can be stably located inside the nasal cavity for use, with a simple structure and convenient operation.

[0024] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
