Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to an oxygen inhalation atomization device. BACKGROUND

[0002] Hypoxia can cause damage to multiple systems and organs of the human body, and the degree of damage is closely related to the degree of hypoxia. Therefore, after surgery such as general anesthesia, patients should follow the medical advice of low-flow oxygen inhalation in the ward. In this process, an oxygen inhalation auxiliary device is needed. The oxygen inhalation auxiliary device is the most commonly used medical consumable in clinical practice, which is mainly divided into two types: nasal catheter and oxygen inhalation mask. After ear-nose-throat surgery, the patient's nasal cavity is filled with a large amount of hemostatic material, so that the patient can only breathe through the mouth. Therefore, the nasal catheter oxygen delivery method is not suitable for such patients. The oxygen inhalation mask directly inputs oxygen into the mask when in use, which can cause the patient to feel uncomfortable and suffocated while inhaling oxygen through the mouth. The nasal catheter that cannot be placed in the nasal cavity can only be held in the patient's mouth, but the head of the nasal catheter is relatively small, and the patient cannot easily hold it.

[0003] Therefore, an oxygen inhalation auxiliary device that can assist the patient in breathing through the mouth is designed. The device is specifically an oxygen inhalation atomization device. CONTENT OF THE UTILITY MODEL

[0004] In order to overcome the problems in the background art, the utility model adopts the following technical solutions:

[0005] An oxygen inhalation atomization device comprises a positioning cover, a mouthpiece, and a connecting pipe. The positioning cover has a convex surface and a concave surface, and a spherical cavity is arranged between the convex surface and the concave surface. The mouthpiece is connected to the positioning cover and has an internal cavity. A plurality of air holes are arranged on the outer wall of the mouthpiece and are in communication with the internal cavity. When the mouthpiece is connected to the positioning cover, the spherical cavity faces the concave surface, and the spherical cavity is in communication with the internal cavity. The connecting pipe comprises a pipe body and a spherical head connected to each other. The spherical head is matched with the spherical cavity, and the connecting pipe is connected to the positioning cover by the spherical head. When the connecting pipe moves, the spherical head rotates around the center of the spherical head, and the spherical cavity limits the movement of the spherical head along the radial direction of the spherical cavity. When the connecting pipe is connected to the positioning cover by the spherical head, the pipe body is in communication with the internal cavity. In use, the positioning cover is worn on the patient's face with the concave surface facing the patient's face. When worn, the mouthpiece is placed in the patient's mouth, and the pipe body of the connecting pipe is connected to the atomization bottle or the oxygen delivery pipeline. The connecting pipe and the internal cavity are in communication through the spherical cavity, which can directly input the input oxygen into the patient's mouth, thereby maintaining the breathing of the patient with a large amount of hemostatic material in the nasal cavity.

[0006] Furthermore, the positioning cover includes a first connecting cylinder, which extends from the spherical cavity to the outside of the concave surface, and the outer wall of the first connecting cylinder is provided with external threads; the mouthpiece includes a second connecting cylinder, which communicates with the cavity, and the inner wall of the second connecting cylinder is provided with internal threads; when the second connecting cylinder is bolted to the first connecting cylinder, the mouthpiece is connected to the positioning cover.

[0007] Furthermore, the outer wall of the connecting cylinder two is provided with knobs, at least two in number, which are arranged in a circular array around the central axis of the connecting cylinder two. By providing these knobs, the user can connect the mouthpiece to the positioning cover or remove the mouthpiece from the positioning cover by rotating the knobs.

[0008] Furthermore, the spherical cavity penetrates the positioning cover and forms a limiting opening on the convex surface. The inner diameter of the limiting opening is larger than the outer diameter of the tube body, so that the tube body can flexibly rotate about the spherical cavity at different angles.

[0009] Furthermore, the spherical head is provided with a communication port, the outer diameter of which is larger than the inner diameter of the first connecting cylinder. When the central axis of the portion of the tube body near the spherical head coincides with the central axis of the second connecting cylinder, the communication port is coaxial with the connecting cylinder; when the tube body rotates around the center of the spherical cavity and abuts against the limiting opening, the communication port is still connected to the first connecting cylinder.

[0010] Furthermore, a washer is provided on the outer edge of the positioning cover, and the washer is elastic.

[0011] Furthermore, the cavity is equipped with a one-way valve. When the connecting tube communicates with the cavity through the spherical cavity, the fluid in the connecting tube can enter the cavity unidirectionally through the spherical cavity, while the fluid entering and exiting the cavity through the air hole cannot flow back into the spherical cavity through the one-way valve. After the patient inhales oxygen through the mouthpiece, the exhaled air overflows through the gap between the positioning mask and the patient's skin.

[0012] Furthermore, it also includes an atomizing bottle, which is connected to the tube body. When the connecting tube rotates around the axis of the tube body or around the center of the spherical head, it drives the atomizing bottle.

[0013] Furthermore, the pores are evenly distributed on the outer wall of the mouthpiece nozzle, and the central axes of any two pores are not parallel. The pores evenly distributed on the mouthpiece nozzle allow the atomized oxygen to diffuse outward from the cavity in all directions.

[0014] Furthermore, it also includes a connecting strap, which is connected to the positioning cover, and the connection between the connecting strap and the positioning cover forms a closed loop; the number of the connecting straps is at least one.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting up a mouthpiece that can be assembled and disassembled with the positioning mask, patients only need to put the mouthpiece in their mouths when inhaling oxygen. Oxygen can enter the cavity through the connecting tube and the spherical cavity, and enter the patient's oral cavity through the air holes evenly distributed on the outer wall of the mouthpiece. It can passively inhale oxygen, and the positional relationship between the mouthpiece and the positioning mask is fixed. The patient does not need to use their mouth to maintain the position of the mouthpiece, so it has excellent practical effect.

[0017] 2. By setting up a spherical cavity and a spherical head, connecting tubes, and a nebulizer bottle that delivers oxygen to the mouthpiece through the connecting tubes, the device can move flexibly around the center of the spherical cavity at multiple angles, thereby adjusting to a suitable placement position according to the patient's posture or body position.

[0028] The technical solutions of this utility model are clearly and completely described below through specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] An oxygen atomizing device, such as Figures 1-8 As shown, it includes: a positioning cover 1, which has a convex surface 11 and a concave surface 12, and a spherical cavity 13 is provided through between the convex surface 11 and the concave surface 12; an orifice nozzle 2, which is connected to the positioning cover 1, and has a cavity 21 inside, and multiple air holes 22 are provided through the outer wall of the orifice nozzle 2, which communicate with the cavity 21; when the orifice nozzle 2 is connected to the positioning cover 1, the spherical cavity 13 faces the concave surface 12, and the spherical cavity 13 communicates with the cavity 21; and a connecting pipe 3, which includes a pipe body 31 and a spherical head 32 connected together, the spherical head 32 being adapted to the spherical cavity 13, and the connecting pipe 3 being ball-jointed to the positioning cover 1; when the connecting pipe 3 moves, it drives the spherical head 32 to rotate around its own center, and the spherical cavity 13 restricts the spherical head 32 from moving radially; when the connecting pipe 3 is connected to the positioning cover 1 through the spherical head 32, the pipe body 31 communicates with the cavity 21. In use, the positioning mask 1 is worn on the patient's face with its concave side 12 facing the patient's face. The mouthpiece nozzle 2 is inserted into the patient's mouth, and the tube body 31 of the connecting tube 3 is connected to the nebulizer bottle 4 or the oxygen delivery line. Through the connecting tube 3 connected to the cavity 21 via the spherical cavity 13, oxygen can be directly delivered into the patient's mouth, thus maintaining the breathing of a patient whose nasal cavity is packed with a large amount of hemostatic material.

[0030] In some embodiments of this application, such as Figures 1-8As shown, the positioning cover 1 includes a connecting cylinder 14, which extends from the spherical cavity 13 to the outside of the concave surface 12. The outer wall of the connecting cylinder 14 is provided with an external thread 141. The nozzle 2 includes a connecting cylinder 24, which communicates with the cavity 21. The inner wall of the connecting cylinder 24 is provided with an internal thread 241. When the connecting cylinder 24 is bolted to the connecting cylinder 14, the nozzle 2 is connected to the positioning cover 1.

[0031] In some embodiments of this application, such as Figures 1-8 As shown, the outer wall of the connecting cylinder 24 is provided with knobs 23. There are at least two knobs 23, which are arranged in a circular array around the central axis of the connecting cylinder 24. By providing knobs 23, the user can connect the mouthpiece 2 to the positioning cover 1 or remove the mouthpiece 2 from the positioning cover 1 by rotating the knobs 23. When holding, installing and removing the mouthpiece 2, there is no need to touch other parts of the mouthpiece 2, thus effectively preventing the mouthpiece 2 from being contaminated.

[0032] In some embodiments of this application, such as Figures 1-8 As shown, the spherical cavity 13 penetrates the positioning cover 1 and forms a limiting opening 131 on the convex surface 11. The inner diameter of the limiting opening 131 is larger than the outer diameter of the tube body 31, so that the tube body 31 can rotate flexibly about the spherical cavity 13 at different angles. When the spherical head 32 rotates around its own center in the spherical cavity 13, the limiting opening 131 restricts the movement of the tube body 31 within a conical space with the center of the spherical head 32 as the tip.

[0033] In some embodiments of this application, such as Figures 1-8 As shown, the spherical head 32 is provided with a connecting port 321, the outer diameter of which is larger than the inner diameter of the connecting cylinder 14. When the central axis of the part of the tube body 31 near the spherical head 32 coincides with the central axis of the connecting cylinder 24, the connecting port 321 is coaxial with the connecting cylinder 14; when the tube body 31 rotates around the center of the spherical cavity 13 and abuts against the limiting opening 131, the connecting port 321 is still connected to the connecting cylinder 14, so that the tube body 31 and the cavity 21 remain unobstructed when the spherical head 32 moves within the spherical cavity 13.

[0034] In some embodiments of this application, such as Figures 1-8 As shown, a washer 15 is provided on the outer edge of the positioning cover 1, and the washer 15 is elastic. By providing an elastic washer 15, when the positioning cover 1 comes into contact with the patient's face, the washer 15 can undergo elastic deformation according to the contact position and contact pressure with the patient's face. This can increase the contact area between the positioning cover 1 and the patient's face, thereby distributing the pressure applied to the patient's face and reducing the pressure damage to the patient's skin.

[0035] In some embodiments of this application, such asFigures 1-8 As shown, the cavity 21 is equipped with a one-way valve 211. When the connecting tube 3 is connected to the cavity 21 through the spherical cavity 13, the fluid in the connecting tube 3 can enter the cavity 21 unidirectionally through the spherical cavity 13. The fluid entering and exiting the cavity 21 through the air hole 22 cannot flow back into the spherical cavity 13 through the one-way valve 211. After the patient inhales oxygen through the mouthpiece nozzle 2, the exhaled gas overflows through the gap between the positioning cover 1 and the patient's skin.

[0036] In some embodiments of this application, such as Figures 1-8 As shown, it also includes a nebulizer bottle 4, which is connected to the tube body 31. The nebulizer bottle 4 is driven by the axial rotation of the connecting tube 31 or the rotation of the spherical head 32. Alternatively, the tube body 31 can also be connected to a tubing connected to an oxygen delivery device as a source of oxygen input.

[0037] In some embodiments of this application, such as Figures 1-8 As shown, the air holes 22 are evenly distributed on the outer wall of the mouthpiece nozzle 2, and the central axes of any two air holes 22 are not parallel. The air holes 22 evenly distributed on the mouthpiece nozzle 2 allow the atomized oxygen to diffuse outward from the cavity 21 in all directions, so that even when part of the outer wall of the mouthpiece nozzle 2 is in contact with the patient's mouth, oxygen can still be output from other air holes 22. In addition, a connecting strap 5 is included for fixing the positioning cover 1 to the patient's head. The connecting strap 5 is connected to the positioning cover 1, and the connection of the connecting strap 5 and the positioning cover 1 forms a closed loop; the number of connecting straps 5 is at least one.
