Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the field of medical apparatus and instruments, and particularly relates to a nasal oxygen tube with an air bag. BACKGROUND
[0002] An oxygen delivery system such as a breathing machine is a common device in the medical field, needs to be connected and used in conjunction with a nasal oxygen tube, and the nasal oxygen tube is inserted into the nasal cavity of a patient to assist oxygen inhalation.
[0003] However, the existing nasal oxygen tubes all have fixing problems, the nasal oxygen tube can cause local compression for a patient who wears the nasal oxygen tube for a long time, affects local blood transportation and causes skin pressure injury of the patient; in addition, the upper lip tooth part of many old people without teeth collapses, the nasal oxygen tube is easily tilted to make the air outlet abut against the upper end of the nasal cavity, and the breathing ventilation is seriously affected. SUMMARY
[0004] The utility model aims at providing a nasal oxygen tube which can be used by old people without teeth and can be effectively fixed in position.
[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme.
[0006] A nasal oxygen tube with an air bag, comprising a nasal oxygen tube main body with a hollow structure and a nasal cannula arranged on the nasal oxygen tube, one side of the nasal oxygen tube is provided with an air inlet for connecting an oxygen delivery tube, and the surface of the nasal oxygen tube is provided with an air bag.
[0007] The air bag is arranged along the axis direction of the nasal cannula, one side of the air bag close to the nasal cannula is a thin air bag, and the other side of the air bag away from the nasal cannula is a thick air bag.
[0008] Further, the air bag is provided with an inflation hole.
[0009] Further, the thin air bag abuts against the gum of the patient, and the thick air bag abuts against the collapsed part of the upper lip tooth of the patient.
[0010] The utility model has the advantages that:
[0011] By arranging the air bag with one side thin and the other side thick on the nasal oxygen tube, the nasal oxygen tube can be fixed on the face of the old people without teeth, meanwhile, the patient can also adjust the inflation amount through the inflation hole to adjust the position of the nasal oxygen tube, effectively prevent the skin pressure injury caused by local compression, and the utility model has great improvement compared with the prior art.
[0012] The above description is only a summary of the technical scheme of the utility model, in order to more clearly understand the technical means of the utility model, and the content of the specification can be implemented, the following preferred embodiments of the utility model are described in detail in cooperation with the drawings. BRIEF DESCRIPTION OF DRAWINGS
[0013] Figure 1 Front view structure schematic diagram of nasal oxygen tube with air bag according to an embodiment of the present application is shown in the figure.
[0014] Figure 2 Back view structure schematic diagram of nasal oxygen tube with air bag according to an embodiment of the present application is shown in the figure.
[0015] Explanation of figure mark: 1, nasal oxygen tube main body; 2, nasal cannula; 3, air bag; 31, thin air bag; 32, thick air bag; 4, air inlet. DETAILED DESCRIPTION
[0016] The technical scheme of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the protection scope of the present application.
[0017] In the description of the present application, it should be noted that unless explicitly specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0018] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as there is no conflict.
[0019] Please see Figure 1 The nasal oxygen tube with air bag according to a preferred embodiment of the present application comprises a nasal oxygen tube main body 1 with hollow structure and a nasal cannula 2 arranged on the nasal oxygen tube, an air inlet 4 for connecting the oxygen supply tube is arranged on one side of the nasal oxygen tube, and an air bag 3 is arranged on the surface of the nasal oxygen tube.
[0020] The air bag 3 is arranged along the axis direction of the nasal cannula 2, the side of the air bag 3 close to the nasal cannula 2 is a thin air bag 31, and the side of the air bag 3 away from the nasal cannula 2 is a thick air bag 32.
[0021] Specifically, the air bag 3 is provided with an inflation hole for adjusting the inflation amount of the air bag 3.
[0022] Working principle:
[0023] The thin air bag 31 is pressed against the patient's gums, and the thick air bag 32 is pressed against the patient's upper lip teeth. The soft air bag 3 can reduce local pressure while fixing the nasal oxygen tube. In addition, the inflation amount of the air bag 3 can be adjusted through the inflation hole, and the patient can adjust the inflation amount and the fixing position.
[0024] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.
