Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an anti-falling type respiratory sprayer. Background Art

[0002] In the treatment of respiratory diseases, drugs need to be delivered directly to the respiratory tract and lungs to achieve rapid and effective treatment. With the increasing incidence of respiratory diseases and people's increasing attention to health, the market demand for respiratory nebulizers continues to grow, and anti-drop respiratory nebulizers are an important component of this market.

[0003] Traditional respiratory nebulizers generally use straps, Velcro or hanging ears to fix the mask to the patient's face. However, in actual use, the straps or Velcro directly fix the mask to the patient's face, and the tension during the restraint is not easy to adjust automatically. If the restraint is too tight, it is easy to cause strangulation marks, resulting in poor comfort and affecting the user experience. Loose restraints can easily cause the mask to fall off or shift. Masks fixed by hanging ears have poor stability during use, and accidental touch can easily cause the mask to fall off, making them less suitable for use. Summary of the invention

[0018] The anti-falling respiratory sprayer provided by the present invention has the following advantages:

[0019] By providing an adjustment structure, the mask is covered on the patient's face through a sealing pad, and the sealing pad is a silicone pad, which increases the comfort of the mask at the contact position with the patient's face and enhances the sealing between the mask and the patient's face. When the patient exhales, the air pressure inside the mask increases, and the gas enters the inside of the flow channel through the one-way exhaust valve. The sealing pad is inflated and deformed, increasing the contact area between the sealing pad and the patient's face, further improving the comfort and sealing of the mask when in use;

[0020] Furthermore, the mask is bound to the patient's face through the magic hair and the connecting tube, and the gas inside the flow channel enters the inside of the connecting belt through the connecting tube, causing the connecting belt to deform, and the tension of the connecting belt can be finely adjusted, while avoiding the situation where the connecting belt is too tight and easy to cause strangulation marks, and the mask is easy to fall off and shift due to loose binding. When the air pressure is too high, the one-way pressure relief valve will perform pressure relief processing, so that the mask is always comfortably fixed on the patient's face, realizing that the device is easy to automatically adjust the tension and has the function of preventing falling off, thereby improving the stability and comfort of the respiratory nebulizer when in use;

[0021] Furthermore, one end of the clamping block is clamped and inserted into the interior of the first clamping groove, so that one end of the clamping block is connected to one end of the preheating tube. As the air pressure inside the mask increases, the airflow enters the interior of the clamping pad through the air guide tube. After the clamping pad is inflated, it is clamped with the clamping block through the second clamping groove, thereby preventing the clamping block from falling off from the interior of the clamping seat due to external force, and further improving the anti-falling performance of the device.

[0022] By setting up a preheating structure, when the patient exhales, the gas discharged from the mouth and nose has temperature, and the preheating tube will absorb the heat in the gas to slightly preheat the medicine gas inside the preheating tube, thereby preventing cold air from directly entering the inside of the mask and making the patient feel uncomfortable when absorbing cold air;

[0023] Furthermore, the positions of the spoiler holes between adjacent spoiler plates are different, so that the medicine gas inside the preheating tube is slowed down by the spoiler plate, the medicine gas flow speed is extended, and the medicine gas slowly enters the inner side of the mask, making the patient breathe more comfortably;

[0024] Furthermore, under the cutting action of the grid, the medicinal gas collides with it, making the disturbance more complete and effectively breaking up the water droplets in the medicinal gas, making the medicinal gas mixed more completely, and improving the quality effect of the patient's inhalation.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-Figure 10 The present invention provides an anti-falling respiratory sprayer, which includes a mask 1.

[0038] Reference Figure 1-Figure 4As shown, an adjustment structure 2 is fixed at the edge of the mask 1 that contacts the face, and the adjustment structure 2 includes a sealing gasket 21, a one-way pressure relief valve 22, a one-way exhaust valve 23 and a flow channel 24. The sealing gasket 21 is fixed at the edge of the mask 1 that contacts the face, and a flow channel 24 is arranged inside the sealing gasket 21. A one-way exhaust valve 23 is fixed on the inner wall of one side of the sealing gasket 21, and a one-way pressure relief valve 22 is fixed on the outer wall of one side of the sealing gasket 21. The sealing gasket 21 is a silicone gasket, and one end of the one-way pressure relief valve 22 and the one-way exhaust valve 23 are both connected to the flow channel 24.

[0039] The mask 1 is covered on the patient's face through the sealing pad 21. The sealing pad 21 is a silicone pad, which makes the mask 1 come into comfortable and close contact with the patient's face. When the patient exhales, the air pressure inside the mask 1 increases, and the gas enters the interior of the flow channel 24 through the one-way exhaust valve 23. The sealing pad 21 is inflated and deformed, causing the sealing pad 21 to deform and increase the contact area with the patient's face.

[0040] Reference Figure 1-Figure 3 As shown, the outer walls on both sides of the mask 1 are evenly and movably installed with a restraining structure 3, the restraining structure 3 includes a connecting belt 31, a binding belt 32, magic bristles 33, magic raw hair 34 and a connecting tube 35, the connecting belt 31 is movably installed on the outer walls on both sides of the mask 1, a connecting tube 35 is fixed on the outer wall of one end of the connecting belt 31, and a binding belt 32 is fixed on the end of the connecting belt 31 away from the mask 1, the magic bristles 33 are fixed on the outer wall of the binding belt 32 on one side of the mask 1, and the magic raw hair 34 is fixed on the inner wall of the binding belt 32 on the other side of the mask 1, the interior of the connecting belt 31 is hollow, one end of the connecting tube 35 is fixedly connected to one side of the sealing gasket 21, and the connecting belt 31 and the sealing gasket 21 are connected through the connecting tube 35.

[0041] The mask 1 is tied to the patient's face through the magic hair 34 and the connecting tube 35. The gas inside the flow channel 24 enters the interior of the connecting belt 31 through the connecting tube 35, causing the connecting belt 31 to deform. The tension of the connecting belt 31 can be fine-tuned, and at the same time, it is avoided that the connecting belt 31 is too tight and easy to cause strangulation marks, and the mask 1 is easy to fall off or shift due to loose binding. When the air pressure is too high, the one-way pressure relief valve 22 will perform pressure relief processing, so that the mask 1 is always comfortably fixed on the patient's face, preventing the mask 1 from falling off during use.

The clamping pad 42 is hollow, one end of the air guide tube 45 is connected to the clamping pad 42, and the clamping block 43 is connected to the medicine delivery tube 44.

[0043] One end of the clamping block 43 is connected to the output end of the medication air pump, and the other end of the clamping block 43 is clamped and inserted into the first clamping groove 411, so that one end of the clamping block 43 is connected to one end of the preheating tube 51. As the air pressure inside the mask 1 increases, the airflow will enter the interior of the clamping pad 42 through the air guide tube 45. After the clamping pad 42 is inflated, it is clamped with the clamping block 43 through the second clamping groove 431, thereby preventing the clamping block 43 from falling off from the inside of the clamping seat 41 due to external force.

[0044] Reference Figure 3 , Figure 4 and Figure 7-10 As shown, a preheating structure 5 is fixed at the bottom of the mask 1, and the preheating structure 5 includes a preheating tube 51, a fixed shaft 52, a connecting seat 53, an air jet cover 54 and a spoiler 55.

[0045] When the patient exhales, the gas discharged from the mouth and nose is heated. The preheating tube 51 will absorb the heat in the gas to slightly preheat the medicinal gas inside the preheating tube 51, thereby preventing cold air from directly entering the interior of the mask 1. The positions of the spoiler holes 551 between adjacent spoiler plates 55 are not the same, so that the medicinal gas inside the preheating tube 51 is slowed down by the spoiler effect of the spoiler plate 55, and the preheating time of the medicinal gas is extended. The medicinal gas slowly enters the inner side of the mask 1, making the patient's breathing more comfortable.
