Description

Technical Field

[0001] The utility model relates to the technical field of medical oxygen inhalation, in particular to an anti - falling nasal suction tube. Background Art

[0002] In the medical field, oxygen inhalation therapy is an important treatment method. By inhaling oxygen, the partial pressure of oxygen in the alveoli is increased, hypoxia symptoms are improved, and the life activities of the body are maintained. It is an important method for treating or assisting in the treatment of many diseases. Currently, the wearing method of the double - nasal oxygen inhalation tube used clinically is: inserting the nasal suction head into the nostril, clamping the tube behind the ear, and tightening it at the chin to fix the nasal suction tube firmly.

[0003] However, in the prior art, the nasal suction heads are all inserted straight into the nasal cavity. If the patient lowers the head or tilts the head, the tube clamped behind the ear is likely to loosen and fall off, resulting in the nasal suction head falling out of the nostril, which can easily make the patient feel uncomfortable and have a poor experience. Secondly, when the straight - through nasal suction tube is not fixed firmly, it is easy to stimulate the patient's nasal cavity. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an anti - falling nasal suction tube to solve the above problems.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] An anti - falling nasal suction tube includes an air duct and two nasal suction heads connected to the air duct at a certain angle. The nasal suction heads are arc - shaped structures conforming to the human nasal cavity structure. There are also two movable parts on the air duct to expand the nasal suction heads to both sides. An arched nasal sticker is provided above the air duct, and symmetrically arranged silicone strips are provided on the arched nasal sticker, and the inclination angle of the silicone strips conforms to the structure on both sides of the human nasal wings.

[0007] In the above - mentioned summary of the utility model, further, the two movable parts are arranged on the air duct back to back with respect to the nasal suction heads, and the distance between the two movable parts is greater than the distance between the two nasal suction heads.

[0008] In the above - mentioned summary of the utility model, further, the two movable parts are respectively arranged at the arc - shaped arch parts of the two nasal suction heads.

[0009] In the above - mentioned summary of the utility model, further, the movable part is composed of a cylinder and a sphere.

[0010] In the above - mentioned summary of the utility model, further, the inner parts at both ends of the air duct are of an enlarged - diameter structure, and the wall thickness at both ends of the air duct is greater than the wall thickness of the middle section.

[0011] In the above description of the utility model, further, a first partition is provided inside the air duct along its length direction. The first partition is in a zigzag structure. The first partition divides the inner cavity of the middle section of the air duct into a non-communicating upper and lower channels, namely channel one and channel two. Channel one is communicated with the left end inlet of the air duct, and channel two is communicated with the right end inlet of the air duct. The two nasal suction heads are both communicated with channel one and channel two.

[0012] In the above description of the utility model, further, a second partition is provided inside each of the two nasal suction heads. The second partition divides the inner cavity of the nasal suction head into an upper and lower arranged air outlet channel and an air supply channel. The air outlet channel is communicated with channel one, and the air supply channel is communicated with channel two.

[0013] In the above description of the utility model, further, the length of the second partition is shorter than the length of the nasal suction head.

[0014] The beneficial effects of the present utility model are:

[0015] The arc-shaped nasal suction head that conforms to the human nasal cavity structure can prevent the nasal straw from being dislocated when the patient's head moves, reducing the probability of detachment. By squeezing the movable part by hand, the nasal suction head can be expanded to both sides, which is convenient for removing and putting on the nasal straw at any time, with convenient operation and improved patient experience. At the same time, the arc-shaped nasal suction head can play a certain buffering role for the oxygen in its inner cavity compared with the straight-through nasal suction head, avoiding a large impact on the nostrils.

[0022] The following describes the implementation modes of the present utility model through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation modes. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0023] Please refer to the attached Figure 1-2 As shown in the figure, an anti - shedding nasal suction tube includes an air duct 1 and two nasal suction heads 2 that are connected to the air duct 1 at a certain angle. The nasal suction heads 2 are arc - shaped structures that conform to the human nasal cavity structure, so that the nasal suction heads 2 can be stably placed in the nostrils and will not fall off with the swing of the patient's head. Since the arc - shaped nasal suction heads 2 cannot be directly inserted into the patient's nostrils immediately and may even cause discomfort to the patient's nostrils, therefore, two movable parts 3 for expanding the nasal suction heads 2 to both sides are provided on the air duct 1. Since the nasal suction tube itself is made of a soft material, only by gently pinching the two movable parts 3 with one hand can the nasal suction heads 2 be expanded to both sides, and then inserted into the patient's nostrils. After releasing the movable parts 3, the nasal suction heads 2 are automatically stuck in the patient's nostrils and are not easy to fall off; at the same time, the arc - shaped nasal suction heads 2 can play a certain buffering role for the oxygen in their inner cavities compared with the straight - through nasal suction heads, avoiding a large impact on the nostrils;

[0024] An arched nasal sticker 4 is provided above the air duct 1. The nasal suction tube is attached to the patient's face through the arched nasal sticker 4. Symmetrically arranged silicone strips 5 are provided on the arched nasal sticker 4. The inclination angle of the silicone strips 5 conforms to the structure on both sides of the human nasal wings, enabling the nasal suction tube to better fit the outside of the nose and better maintain the balance with the nostrils and not easy to shake.

[0025] Among them, the two movable parts 3 are arranged on the air duct 1 facing away from the nasal suction heads 2. The movable parts 3 are composed of a cylinder and a sphere. Since the air duct 1 is made of a soft material, by pinching the two spheres towards the middle, the air duct 1 bends to one side of the movable part 3 under the pulling force of the spheres, thereby driving the two nasal suction heads 2 arranged on the other side of the air duct 1 to expand to both sides respectively, and the two nasal suction heads 2 can be inserted into the patient's nostrils. Moreover, the distance between the two movable parts 3 is greater than the distance between the two nasal suction heads 2, which is labor - saving and simple and convenient to operate.

[0026] In the above - mentioned embodiment, preferably, the inner parts at both ends of the air duct 1 are of an enlarged - diameter structure, and the wall thickness of both ends of the air duct 1 is greater than the wall thickness of the middle section. One is to facilitate the insertion and removal of the pipe joint, and the other is because tensile deformation is likely to occur when inserting and removing the pipe joint. By increasing the wall thickness, the strength of the air duct 1 is improved.

[0027] Please refer to the attachedFigure 4 As shown, a first partition 6 is provided inside the air duct 1 along its length direction. The first partition 6 divides the inner cavity of the middle section of the air duct 1 into a non-communicating upper and lower arranged passage 7 and passage 8. The first partition 6 is in a zigzag structure, that is, a stepped structure is formed at the two ends of the air duct 1 where the passage 7 and passage 8 are located, which is convenient for processing. The passage 7 communicates with the left end inlet of the air duct 1, and the passage 8 communicates with the right end inlet of the air duct 1. The two nasal tips 2 are both communicated with the passage 7 and the passage 8. Specifically, both the passage 7 and the passage 8 can be used to transport oxygen at the same time, or one can be used to transport oxygen and the other can be used to absorb other gases or for exhalation. For example, in the process of treatment or health care, sometimes two gases need to be mixed and used immediately. During anesthesia, in order to facilitate the control of the dosage of anesthetic gas, the anesthetic gas (nitrous oxide) and the oxygen required for breathing are respectively supplied to the patient, and the nitrous oxide and oxygen will not be pre-mixed and stored in advance. That is, the passage 7 is used to transport oxygen, and the passage 8 is used to transport anesthetic gas. The two passages do not communicate with each other and work independently. However, because one nasal tip 2 is respectively communicated with the passage 7 and the passage 8, the anesthetic gas and oxygen enter the patient's nasal cavity at the same time.

[0028] Please refer to the attached Figure 3 As shown, a second partition 9 is provided inside each of the two nasal tips 2. The second partition 9 divides the inner cavity of the nasal tip 2 into an upper and lower arranged air outlet passage 10 and air supply passage 11. The air outlet passage 10 communicates with the passage 7, and the air supply passage 11 communicates with the passage 8. Specifically, when pulse oxygen supply is selected, oxygen is only supplied in the passage 7, and no oxygen or other gases are supplied in the passage 8. Oxygen then enters the air supply passages 11 of the two nasal tips 2 through the passage 8. That is, the two nasal tips 2 can supply oxygen to the patient simultaneously through the air supply passages 11. Then, a part of the gas exhaled by the patient enters the passage 7 through the upper air outlet passage 10, thereby reducing the problem of airflow interference and intermittent oxygen supply, and at the same time achieving the purpose of saving oxygen.

[0029] In the above embodiment, preferably, as shown in the attached Figure 1 As shown, the length of the second partition 9 is shorter than the length of the nasal tip 2. This situation is mainly applicable when the passage 7 and the passage 8 supply oxygen or transport other substances at the same time. Because direct oxygen supply is likely to cause a greater impact on the patient's nostrils and easily lead to nasal congestion. By combining the two small diameters into a large diameter at the outlet end of the nasal tip, the flow rate is greatly reduced when the two small diameters converge into the large diameter, avoiding a greater impact on the nostrils and not easily causing nasal congestion.

[0030] Embodiment 2:

[0031] Please refer to the attached Figure 5As shown in the figure, the difference between this embodiment and Embodiment 1 is that in this embodiment, the two movable parts 3 can also be respectively arranged at the arc-shaped arches of the two nasal suction heads 2. The movable part 3 is composed of a cylinder and a sphere. This embodiment requires manual operation with both hands. Specifically, hold the spheres on one side with both hands and gently pull them towards the two ends of the air guide tube 1, thereby driving the arc-shaped nasal suction heads 2 to expand to both sides, and then the nasal suction heads 2 can be inserted into the patient's nostrils. The operation is simple, convenient, and fast, and is applicable to different application scenarios.

[0032] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0033] The above-described embodiments only represent the specific implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation of the patent scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
