Description

Technical Field

[0001] The present application relates to the field of medical atomization technology, and in particular to a nebulizer. Background Art

[0002] A medical nebulizer is a device that atomizes liquid medicine into tiny particles. The medicine enters the respiratory tract and is deposited in the lungs through inhalation, thus achieving painless treatment of various upper and lower respiratory system diseases.

[0003] Common portable nebulizers, such as compressed air nebulizers, inject liquid medicine into the top of the cup of the nebulizer, insert an airway at the bottom, so that aerosol is generated in the cup and sprayed out from the side hole of the cup. This nebulizer is suitable for patients who are sitting. For some bedridden patients, because the nebulizer and the inhalation structure such as the mask are fixedly connected and the angle cannot be adjusted, the nebulizer will tilt when used by bedridden patients. When the tilt angle is too large, the liquid medicine may choke into the mouth from the side hole of the cup, affecting the patient's nebulization treatment; secondly, the nebulization process usually takes 15-20 minutes. When the patient lies down, he may forget that he is still undergoing nebulization treatment and turn over unconsciously, so that the cup of the nebulizer may swing. When the cup and the bed are basically parallel, the liquid medicine in the cup may also flow out from the top of the cup and contaminate the bed. Therefore, how to make the nebulizer suitable for patients who are sitting or lying down to prevent the liquid medicine from choking and pouring out of the cup is a problem to be solved.

[0026] The defect of the prior art that the nebulizer tilts, which is not conducive to the nebulization treatment of patients. After careful analysis, the inventor found that the reason for the above-mentioned problem of the existing nebulizer is mainly that the cup body of the nebulizer and the structure connecting the inhalation mask are made of hard plastic. When the inhalation mask swings at an angle, the cup body and will swing to a corresponding angle. Therefore, if the patient is lying down for nebulization treatment, the cup body tilts, and the medicine liquid easily flows from the mist outlet to the patient's mouth and nose, or flows out from the top of the cup body. The above situation is not convenient for the patient to perform nebulization treatment. In addition, when the patient is lying down for nebulization treatment, he may have no concept of time and turn over during the nebulization treatment. At this time, the nebulizer may swing with the patient's turning over, and the medicine liquid flows out from the top of the cup body, thereby contaminating the bed and affecting the treatment. Based on the above analysis, the inventor made structural improvements to the nebulizer.

[0027] like Figure 1-6 As shown, a nebulizer includes a cup body 1, a side wall of the cup body 1 is provided with a mist outlet, a mist outlet pipe 11 is provided at the mist outlet, and also includes a hose 3 and a connecting pipe 4 for adjusting the patient's atomization angle; the hose 3 can be a bendable tube made of rubber material, or a corrugated tube or other existing bendable tubes, the hose 3 is arranged in the mist outlet pipe 11, the connecting pipe 4 is sleeved on the hose 3, and is detachably connected to the mist outlet pipe 11, the other end of the connecting pipe 4 is provided with a dual-purpose joint 5, the dual-purpose joint 5 is provided with an elastic member 52 moving along the dual-purpose joint 5, the other end of the dual-purpose joint 5 is provided with an inhalation end 6, the inhalation end 6 can be any one of a mask, a nozzle tube, a nasal cannula or a nasal catheter. When the patient is sitting for nebulization treatment, the connecting tube 4 is put on the hose 3 and connected to the mist outlet pipe 11, and then the connecting tube 4 is connected to the dual-purpose joint 5, and the nebulization treatment can be carried out; when the patient is lying in bed for nebulization treatment, the connecting tube 4 is removed from the hose 3, and then the dual-purpose joint 5 is put on the hose 3, and the elastic member 52 is moved to clamp the dual-purpose joint 5 to clamp the hose 3. The suction end 6 can be swung to a corresponding angle through the connection of the hose 3, which is convenient for patients lying in bed to carry out nebulization treatment.

[0028] The hose 3 needs to be stably and tightly connected to the cup body 1 to avoid gaps that may cause the drug mist to escape. Therefore, a flange 31 is provided at the left end of the hose 3. The flange 31 and the inner wall of the cup body 1 are tightly connected by glue, which not only ensures the sealing performance, but also prevents the hose 3 from being taken out when the connecting tube 4 is removed from the hose 3.

[0029] The mist outlet pipe 11 and the connecting pipe 4 are threadedly connected, that is, the mist outlet pipe 11 is provided with an internal thread, and the connecting pipe 4 is provided with an external thread. When the mist outlet pipe 11 and the connecting pipe 4 are connected, the connecting pipe 4 is screwed into the mist outlet pipe 1. The threaded connection makes it very convenient to install and remove the connecting pipe 4.

[0030] The function of the dual-purpose connector 5 is that when the patient is sitting for nebulization treatment, it can be connected to the connecting tube 4; when the patient is lying for nebulization treatment, it can be fixed to one end of the hose 3. Therefore, in order to achieve the above-mentioned functions, the structure of the dual-purpose connector 5 includes a fixed tube 51 made of medical plastic, and the side wall of the fixed tube 51 is provided with a threaded tube 53 which is detachably connected to the connecting tube 4, the inner wall of the threaded tube 53 is provided with a thread, and one end of the connecting tube 4 connected to the threaded tube 53 is provided with an external thread. The position where the threaded tube 53 and the fixed tube 51 are connected is trumpet-shaped, extending toward the connecting tube 4 and gradually becoming parallel to the inner wall of the connecting tube 4, and the dual-purpose connector 5 can be fixed to the connecting tube 4 through the threaded tube 53.

[0031] In order to connect the dual-purpose connector 5 to the hose 3, a plurality of grooves 54 are provided on the side of the threaded tube 53, and the elastic member 52 is sleeved on the fixed tube 51 to adjust the diameter of the threaded tube 53. Specifically, the elastic member 52 on the fixed tube 51 is sleeved on the threaded tube 53, and the threaded tube 53 is subjected to the pressure of the elastic member 52. Since the grooves 54 are provided on the side of the threaded tube 53, the portion of the threaded tube 53 with the grooves 54 is contracted, thereby reducing the diameter of the threaded tube 53.

[0032] The threaded tube 43 is made of plastic, and the elastic member 52 is a metal ring, so that when the elastic member 52 moves, the threaded tube 53 is deformed while the elastic member 52 is not deformed.

[0033] In order to enable the dual-purpose joint 5 to be connected to the hose 3, the end of the hose 3 away from the mist outlet pipe 11 is arranged between the fixed tube 51 and the threaded tube 53. The fixed tube 51 located inside the hose 3 is equivalent to being used as a support. When the elastic member 52 drives the threaded tube 53 to contract, the thread of the threaded tube 53 will be pressed on the surface of the hose 3. During the squeezing process, the inner wall of the hose 3 will fit with the outer wall of the fixed tube 51, thereby fixing the hose 3.

[0034] In order to prevent the medicine liquid from flowing out from the top of the cup body 1 when the cup body 1 is tilted, a leak-proof cover 2 is provided on the top of the cup body 1, and a liquid injection port 21 is provided in the middle of the leak-proof cover 2. When the cup body 1 is tilted, the medicine liquid on the inner wall contacts the inner wall of the leak-proof cover 2, but will not be higher than the liquid injection port 21, and therefore will not flow out from the top of the cup body 1.

[0035] In order to improve the flatness of the bottom of the atomizer and prevent it from tipping over, a bowl-shaped base 8 is threadedly connected to the bottom of the cup body 1. A notch is provided on the base 8 for adjusting the angle of the air guide tube 8 of the cup body 1. In this way, the bottom of the atomizer is flat, and the atomizer can be placed on a desktop or other flat surface without having to be held in the hand for a long time.

[0036] When using the nebulizer, the structure of the nebulizer is adjusted according to the needs of the patient. When the patient is sitting for nebulization treatment, the connecting tube 4 is screwed onto the mist outlet tube 11, and then the dual-purpose connector 5 is screwed onto the other end of the connecting tube 4. Figure 2 As shown, at this time, the fixed tube 51 is arranged inside the hose 3, the threaded tube 53 and the connecting tube 4 are threadedly connected, and then the tightening piece 52 is pushed to the side of the threaded tube 53 with the groove 54, and the connection state of the threaded tube 53 and the connecting tube 4 is locked, and the atomization treatment can be carried out; when the patient lies down for atomization treatment, the dual-purpose joint 5 and the connecting tube 4 are disassembled in sequence, and then the dual-purpose joint 5 and the hose 3 are connected, and the tightening piece 52 is pushed to the side of the threaded tube 53 with the groove 54, and the connection state of the threaded tube 53 and the hose 4 is locked, as shown in FIG. Figure 5 As shown, at this time, the angle of the suction end 6 can be adjusted through the hose 3 to facilitate the nebulization treatment for lying patients.

[0037] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above based on the concept of the present application should all be within the protection scope of the present application.
