This rotating joint solves the problem that existing nebulizer cups cannot rotate relative to the mask, facilitating nebulization therapy for patients while lying down.

Description

Technical Field

[0001] The utility model relates to an atomizer device used for patients in hospitals, in particular to a rotatable joint and an atomizer with the rotatable joint. Background Art

[0002] For respiratory diseases, such as asthma, doctors usually use a nebulizer device (nebulizer for short) for nebulization treatment. Nebulization inhalation therapy refers to the use of a nebulizer to disperse the nebulized liquid into tiny droplets or liquid particles, which enter the patient's respiratory tract and lungs, so that the drug is deposited on the lesions, thereby achieving the purpose of treating the disease. At present, the nebulizer used in clinical practice consists of three parts: a nebulizer cup, a mask, and an oxygen tube. The mist outlet of the nebulizer cup is directly connected to the mask. When the patient sits, the nebulizer cup is in a position horizontal to the human body and vertical to the ground. For patients who are comatose, critically ill, or absolutely bedridden and cannot sit up, the nebulizer cup is horizontal to the ground during the nebulization process, which makes it easy for the drug to fail to reach the atomized state, or even flow back from the mask to the patient's face. Utility Model Content

[0003] In order to solve the problem that the existing atomizer cup is directly connected to the mask and cannot rotate relative to the mask, the utility model provides a rotatable joint and an atomizer with a rotatable joint. The rotatable joint is placed between the atomizer cup and the mask. The atomizer cup is connected to the mask through the rotatable joint. The medicine mist in the atomizer cup enters the mask through the rotatable joint, and the patient inhales the medicine mist in the mask. The medicine mist is the medicine in the atomized state. The rotatable joint can rotate, which solves the problem that the existing atomizer cup cannot rotate relative to the mask, and is convenient for the patient to perform atomization treatment when lying in bed.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model provides a rotary joint, comprising an outer shell, an inner shell, an output pipe and an input pipe, wherein the outer shell is a partial shell of a first sphere, and the inner shell is a partial shell of a second sphere; the outer shell is sleeved on the outer surface of the inner shell, and the center positions of the first sphere and the second sphere are consistent, so that the outer shell can rotate relative to the inner shell;

[0006] The output tube is arranged on the outer shell, the input tube is arranged on the inner shell, and the output tube and the input tube are arranged opposite to each other; the outer shell is surrounded by a first accommodating space, the inner shell is surrounded by a second accommodating space, the first accommodating space and the second accommodating space are connected, and the output tube and the input tube are connected through the first accommodating space and the second accommodating space.

[0007] The outer shell is a hollow sphere with a notch, and the inner shell is a hollow sphere with a notch; the notch of the outer shell is located at one end of the outer shell, and the notch of the inner shell is located at one end of the inner shell. The outer shell is sleeved on the inner shell through the notch of the outer shell, and the notch of the inner shell is located in the first accommodating space. The outer shell and the inner shell are sleeved on the outside of the inner shell through the notch of the outer shell and the inner shell can rotate in the outer shell, and the inner shell will not fall out of the outer shell. The notch of the outer shell and the notch of the inner shell cooperate with each other to realize the relative rotation of the outer shell and the inner shell. The size of the notch can limit the relative rotation angle of the outer shell and the inner shell.

[0008] The inner shell is made of elastic material. The elastic material is elastic plastic or elastic rubber. The elastic material can be squeezed and deformed. After the inner shell is squeezed and deformed, it is placed in the outer shell.

[0009] Alternatively, the housing is composed of two parts, and the two parts of the housing are joined together by fitting or bonding.

[0010] The outer shell is composed of two parts. During the assembly process, the inner shell is first placed between the two parts of the outer shell. The two parts of the outer shell are put together by fitting or bonding, and the outer shell is put outside the inner shell.

[0011] The shell top of the outer shell is connected to one end of the output pipe. The shell bottom of the inner shell is connected to one end of the input pipe.

[0012] The outer shell is substantially spherical, and the inner shell is substantially spherical.

[0013] The inner diameter of the outer shell is slightly larger than the outer diameter of the inner shell. The inner surface of the outer shell fits the outer surface of the inner shell. The inner surface of the outer shell and the outer surface of the inner shell can slide relative to each other. Avoid too large a gap between the inner surface of the outer shell and the outer surface of the inner shell to prevent leakage.

[0014] The rotatable joint is basically spherical. The outer shell is a hollow sphere with a notch, and the inner shell is a hollow sphere with a notch. The notch of the outer shell is located at the lower part of the rotatable joint. The notch of the inner shell is located at the upper part of the rotatable joint.

[0015] Further, the rotatable joint is spherical. The outer shell is 5 / 8 of a hollow sphere, and the other 3 / 8 is a notch, and the notch of the outer shell is located at the lower part of the rotatable joint. The inner shell is 5 / 8 of a hollow sphere, and the other 3 / 8 is a notch, and the notch of the inner shell is located at the upper part of the rotatable joint.

[0016] The utility model also provides an atomizer with a rotatable joint, comprising a mask, a rotatable joint, an atomizer cup and an oxygen tube, wherein the rotatable joint is the rotatable joint provided by the utility model. The bottom of the mask is connected to the output pipe of the rotatable joint, the input pipe of the rotatable joint is connected to the outlet of the atomizer cup, and the inlet of the atomizer cup is connected to the oxygen tube. A vent is provided on the mask. A plurality of vents are provided on the mask. The mask has a lace.

[0017] The rotatable joint is in the shape of a spherical ball, and the rotatable joint can complete the angle adjustment function by rotating the inner shell inward (the side close to the patient is the inner side), outward, leftward, or rightward.

[0018] The function of the atomizer cup is to store the medicine and further atomize the medicine. During use, the medicine is atomized in the atomizer cup and then enters the rotatable joint.

[0019] A rotatable joint (referred to as a rotary joint) is connected below the mask, a joint (i.e. an input tube) is provided below the joint, and the joint is connected to the atomizer cup through the joint. The rotary joint is a multi-angle rotary joint.

[0020] The rotatable joint is composed of two hollow 5 / 8 hemispheres, which are matched inside and outside. The inner side of the lower end of the outer hemisphere (i.e. the outer shell) is a notch, and the inner side of the upper end of the inner hemisphere (i.e. the inner shell) is a notch (the inner side is close to the mask). The entire sphere of the rotatable joint is connected to the mask through the upper hollow cylinder (i.e. the output tube) and is connected to the atomizer cup through the lower hollow cylinder (i.e. the input tube).

[0021] Rotation joint function: The angle adjustment function is completed by rotating the inner hemisphere inward, left, or right. When the patient is in a supine position, semi-recumbent position, or side-lying position, adjust the rotation joint so that the mask fits tightly to the face and the atomizer cup is perpendicular to the ground.

[0022] The complete process of using a nebulizer is as follows: ① Pour the medicine into the nebulizer cup; ② Connect the oxygen tube to the central oxygen source, nebulizer cup, and mask; ③ Adjust the oxygen flow rate to 6-8ml / min to make the medicine in a mist form; ④ Adjust the angle of the rotatable joint; ⑤ Wear the mask on the patient's face.
