Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an aerosol inhalation medication management device and an aerosol inhalation medication component. Background Art

[0002] As the most direct method of medication, inhalation medication has the advantages of quickly reaching the target organ, rapid onset of action, good efficacy, and few side effects. It is becoming increasingly widely used and popular in China. However, inhalation medication requires users to have certain inhalation skills, and good mastery of inhalation skills has a huge impact on the user's medication effect. COPD and asthma are indications for inhalation medication and rely on long-term medication. Whether the medication is used regularly and correctly is directly related to the control of the disease. At the same time, for users of such diseases, timely understanding of their condition can help reduce the number of acute attacks and hospitalizations, effectively slow the progression of the disease, and reduce medical insurance and patient personal expenses.

[0003] Aerosol medication requires a lower level of patient inhalation ability and is more user-friendly for patients with severe symptoms or poor airway conditions. Because aerosols are a form of active drug administration, patients can inhale the drug into the lungs at a lower inspiratory flow rate. However, aerosols have certain requirements for the patient's hand-mouth coordination, and the hand-mouth coordination directly affects the patient's medication effect. Hand-mouth coordination refers to the consistency between the spray action of the hand pressing the spray can and the patient's inhalation action. For example, if the hand presses the aerosol can, the medicine has been sprayed out, and the patient has not actively inhaled. Most of the medicine remains in the mouth, making it difficult to reach the lungs, and the patient's condition is difficult to be effectively treated. Therefore, the hand-mouth coordination directly affects the patient's medication effect.

[0004] The aerosol inhalation medication device in the prior art includes a spray can, a pressurizer and a nozzle. The spray can is located in the pressurizer, and the nozzle is fixed to one end of the pressurizer for the patient to hold in his mouth. When in use, the patient holds the nozzle in his mouth and presses the spray can with his hand. The spray can moves in the pressurizer, and the medicine in the spray can enters the pressurizer. The patient inhales and inhales the medicine into the lungs.

[0005] The aerosol inhalation medication device in the prior art completely relies on the patient's active inhalation, and is unable to understand whether the patient's inhalation action or pressing action occurs, and is even more unable to guide the patient's hand-mouth coordination.

[0034] The embodiment of the utility model provides an aerosol inhalation medication management device, which can detect whether the patient's inhalation action and pressing action occur, thereby facilitating the judgment of the patient's hand-mouth coordination.

[0035] The following combination Figure 1-Figure 4 The technical solution provided by the utility model is described in more detail.

[0036] Embodiment 1:

[0037] The utility model provides an aerosol inhalation medication management device, including a housing assembly, a push button 1, a detection switch 2, an airflow collection tube 3 and a pressure sensor 4, wherein: the housing assembly is fixedly connected to the spray can, the detection switch 2 is fixed in the housing assembly, and when the push button 1 moves under the action of an external force and presses the spray can 300, the push button 1 contacts the detection switch 2, and the detection switch 2 is used to detect whether the medication action has occurred; one end of the airflow collection tube 3 extends into the press 100 and is connected to the inner cavity of the press 100, and the other end of the airflow collection tube 3 extends into the housing assembly and is connected to the pressure sensor 4, and the pressure sensor 4 is used to detect the pressure in the airflow collection tube 3.

[0038] Specifically, the push button 1 is slidably connected to the housing assembly, facilitating a smooth pressing action. Only when the push button 1 presses the spray can does it contact the detection switch 2. The detection switch 2 can be a limit switch or the like as known in the art. The pressure sensor 4 is a well-established technology, and its structure is not described in detail here.

[0039] The aerosol inhalation medication management device provided by the present invention has the following characteristics: when the push button 1 moves under the action of external force and presses the spray can, the push button 1 contacts the detection switch 2, and at this time the detection switch 2 detects that the drug administration action has occurred; because when the patient holds the mouthpiece 200 in his mouth to inhale the medicine, the pressure inside the depressor 100 is negative, and the airflow collection tube 3 is connected to the inner cavity of the depressor 100, that is, the pressure inside the airflow collection tube 3 is also negative. When the pressure sensor 4 detects that the pressure inside the airflow collection tube 3 is negative, it proves that the inhalation action has occurred. When the pressure sensor 4 detects that the pressure inside the airflow collection tube 3 is negative, it proves that the inhalation action has occurred. When the pressure sensor 4 detects that the pressure inside the airflow collection tube 3 is negative, it proves that the inhalation action has not occurred or has ended.

[0040] The above-mentioned aerosol inhalation medication management device can detect whether the patient's inhalation action and pressing action occur, thereby facilitating the judgment of the patient's hand-mouth coordination, facilitating medication guidance, and ensuring the patient's medication effect.

[0041] As an alternative embodiment, see Figure 2 and Figure 3 As shown, the airflow collection tube 3 includes a straight pipe section 31 and a curved pipe section 32 that are fixedly connected and communicated with each other, wherein: the straight pipe section 31 is located outside the shell assembly and extends into the position of the presser 100 near the suction nozzle 200, and the curved pipe section 32 is located inside the shell assembly, and the air outlet of the curved pipe section 32 is communicated with the pressure sensor 4.

[0042] In this embodiment, the pressure in the depressor 100 is indirectly detected by detecting the pressure in the airflow collection tube 3. In order to improve the accuracy of the detection, the straight tube section 31 is extended into the position of the depressor 100 near the suction nozzle 200. In this way, when the patient holds the suction nozzle 200 in his mouth to inhale, the position of the depressor 100 near the suction nozzle 200 is easiest to detect, which facilitates improving the pressure detection sensitivity and accuracy.

[0043] As an alternative embodiment, see Figure 4 As shown, the housing assembly includes a fixed shell 51, in which a snap-fitting cavity 511 is provided. The snap-fitting cavity 511 covers one end of the spray can 300 and is snap-fitted to the spray can. Specifically, a raised strip is provided on the side wall of the snap-fitting cavity 511, and one end of the spray can 300 extends into the snap-fitting cavity 511 and is snap-fitted to the fixed shell 51.

[0044] See also Figure 4 As shown, a guide groove 512 is provided in the housing assembly, a portion of the pressing key 1 extends into the guide groove 512 and can move along the guide groove 512 under the action of an external force, thereby pressing the spray can 300 .

[0045] The guide groove 512 guides the movement of the push key 1 , ensuring that the push key 1 moves vertically when subjected to external force, and preventing the push key 1 from being offset and unable to contact the detection switch 2 .

[0046] As an alternative embodiment, see Figure 4 As shown, the push button 1 includes a push portion 11 and a positioning column 12, wherein: the push portion 11 is fixedly connected to the positioning column 12, the push portion 11 is used for direct pressing by the hand, the positioning column 12 extends into the guide groove 512, and an elastic reset member 6 is provided on the outer sleeve of the positioning column 12, one end of the elastic reset member 6 is a fixed end, and the other end is against the push button 1.

[0047] The pressing portion 11 is the direct contact point for the patient's hand to press. The pressing portion 11 and the positioning post 12 are integrally formed, improving the stability of the structure. The elastic return member 6 can be a return spring. When the external force acting on the pressing portion 11 is removed, the elastic return member 6 is used to drive the pressing key 1 back to its original position, making it easier to press it again.

[0048] See also Figure 4 As shown, by pressing the pressing portion 11, the positioning column 12 moves downward along the guide groove 512, and the elastic reset member 6 is compressed until the pressing portion 11 contacts the detection switch 2. At this time, the positioning column 12 presses the spray can 300, and the spray can 300 moves the medicine to spray into the presser 100.

[0049] As an alternative embodiment, see Figure 4 As shown, the shell assembly includes a shell 52, which is fixedly connected to the fixed shell 51. A limit opening 521 is provided on the shell 52, and the press key 1 is located in the limit opening 521. When in a non-pressed state, the press key 1 is against the top wall of the limit opening 521.

[0050] The above structure can prevent the push button 1 from being separated from the housing assembly, thereby ensuring the stability of the structure.

[0051] As an optional embodiment, the aerosol inhalation medication management device of this embodiment further includes a control unit, electrically connected to both the detection switch 2 and the pressure sensor 4. The control unit is configured to record the pressing action time t0 based on the electrical signal from the detection switch 2, and the inhalation start time t1 and the inhalation end time t2 based on the electrical signal from the pressure sensor 4, thereby determining the coordination of the pressing and inhalation actions. Specifically, the aerosol inhalation medication management device further includes a display unit, electrically connected to the control unit, for displaying the determination result on the display unit. The display unit includes a display screen 7.

[0052] Specifically, this embodiment divides the evaluation of medication skills into five situations based on the patient's medication situation. The pressing action time point t0 (drug administration time point), the inhalation start time point t1, and the inhalation end time point t2 are set. In view of the different time points before and after each event, based on long-term experiments, this embodiment stipulates the following evaluation rules for medication skills:

[0053] 1. If t1 is earlier than or equal to t0, but t2-t1 ≥ 2s, the patient's inhalation technique is considered to be up to standard;

[0054] 2. If only the pressing action (also called the drug administration action) is detected but the inhalation action is not detected, it is determined that the patient has not inhaled and is marked as E1;

[0055] 3. If t1 is later than t0, but t2-t1>2s, the patient is judged to have substandard hand-mouth coordination and marked as E2;

[0056] 4. If t1 is earlier than or equal to t0, but t2-t1 < 2s, the patient is judged to have insufficient inspiratory time, and the indicator is E3;

[0057] 5. If t1 is later than t0 and t2-t1<2s, it is judged that the patient's mouth closing coordination is not up to standard and the inhalation time is insufficient, and the mark E4 is displayed; the above marks can be displayed on the display screen 7 for direct observation.

[0058] Based on different error categories, guiding suggestions will be given to patients on their medication operations to help them improve their medication skills and use medication better; the data has remote data function, which sends the collected data to the background for data statistical analysis.

[0059] As an optional implementation, the aerosol inhalation medication management device of this embodiment further includes an alarm unit. The control unit is electrically connected to the alarm unit and is configured to control the alarm unit to sound an alarm when it is determined that the patient's hand-mouth coordination does not meet the standard.

[0060] The alarm unit can be a sound alarm in the prior art, which can play voice or emit a beep, etc. According to the patient's medication skills, it can provide a sound reminder or voice evaluation to remind the patient of the direction and method of improvement.

[0061] As an alternative embodiment, see Figure 2 As shown, the housing assembly further includes an electrical shell 53 , in which electrical components are located, a display screen 7 is located on the electrical shell 53 , and a charging port 8 is also provided on the electrical shell 53 for facilitating charging of the device.
