Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a drug inhalation device with flow detection function. Background Art

[0002] Chronic obstructive pulmonary disease, abbreviated as COPD, is a common, preventable and treatable chronic airway disease characterized by persistent airflow limitation and corresponding respiratory symptoms (dyspnea, cough, sputum); its pathological changes are mainly airway (bronchitis, bronchiolitis) or alveolar abnormalities (emphysema), usually associated with significant exposure to harmful particles or gases. The goal of treatment in the stable phase of COPD is to alleviate current symptoms and reduce the risk of future acute exacerbations, including drug therapy and non-drug therapy. Stable drug therapy is the core content of long-term management. If there are no obvious adverse drug reactions or worsening of the disease, long-term regular drug therapy should be maintained at the same level. At present, most of the stable treatment options for COPD are inhaled drugs. The correct mastery of the inhalation method and good compliance are the guarantee of efficacy. Appropriate inhaled drugs and inhalation devices should be selected according to the patient's condition and inhalation function status.

[0003] However, there is currently no non-invasive detection instrument in clinical practice that can evaluate the dose of inhaled drugs entering the lungs of COPD patients. The existing drug inhalation devices are turned on and the patients absorb the drugs independently. Not only is there some waste in the absorption process, but the inhaled amount cannot be detected, making it difficult to smoothly control the dosage.

[0004] In addition, a survey of primary medical institutions showed that for a long time, the basic medications for COPD in my country were aminophylline and expectorants, and the most commonly used drugs for acute attacks were antibiotics and oral glucocorticoids. As the most important therapeutic drug for chronic airway diseases, inhaled drugs play a fundamental role in the treatment and long-term management of COPD. This suggests that the use of inhaled drugs for COPD patients at the grassroots level needs to be strengthened. The main reason for this phenomenon is that the cost of inhaled drugs exceeds the economic payment ability of patients, especially rural COPD patients.

[0005] Therefore, a reusable drug inhalation device with flow detection is proposed, which can improve the drug efficacy of patients on the one hand and reduce the economic burden of patients on the other hand. Summary of the invention

DETAILED DESCRIPTION

[0035] 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.

[0036] As attached Figure 1-7 The drug inhalation device with flow detection shown in the figure comprises a shell 1, an opening and closing cover 2 is installed on one side of the shell 1, a drug administration control mechanism 8, a guide rod 9, a positioning block 10 and a drug administration tank 11 are installed in the shell 1, the drug administration control mechanism 8 is slidably connected with the guide rod 9, the drug administration tank 11 is clamped between the drug administration control mechanism 8 and the positioning block 10, a top box 3 is installed on the top of the shell 1, a handle 4 is arranged on the top box 3, a breathing tube 5 is installed in the top box 3, a breathing mask 6 is installed at one end of the breathing tube 5, and a plurality of sensing contacts are evenly arranged on the edge of the breathing mask 6 in a circumferential manner;

[0037] A breathing detection system, the breathing detection system includes a timing module for detecting breathing time, an inhalation module for detecting an inhalation state, and an exhalation module for detecting an exhalation state, the timing module includes two timing units, the two timing units are timers, the inhalation module and the exhalation module are each connected to a timing unit, the inhalation module includes an air inlet pipe 16, a first one-way valve 17 and a second mass flowmeter 18, one end of the air inlet pipe 16 is connected to the breathing pipe 5, the other end of the air inlet pipe 16 is equipped with the first one-way valve 17, the air inlet pipe 16 is equipped with a second mass flowmeter 18, the second mass flowmeter 18 is connected to a timer, the exhalation module includes an air outlet pipe 19, a third mass flowmeter 20 and a second one-way valve 21, one end of the air outlet pipe 19 is connected to the breathing pipe 5, the other end of the air outlet pipe 19 is equipped with the second one-way valve 21, the air outlet pipe 19 is equipped with a third mass flowmeter 20, and the third mass flowmeter 20 is connected to another timer;

[0038] The dose release system includes a learning module, a timing module, a driving module and a dose detection module. The learning module is connected to the timing module, the timing module is connected to the driving module, the driving module is connected to the dose detection module, the driving module is connected to the drug administration control mechanism 8, and the learning module is connected to the breathing detection system;

[0039] The dosage detection module includes a spraying pipe 13 and a first mass flow meter 14 . One end of the spraying pipe 13 is connected to the interior of the positioning block 10 , and the other end of the spraying pipe 13 is connected to the breathing tube 5 . The first mass flow meter 14 is installed on the spraying pipe 13 .

[0040] During specific implementation, the patient puts the breathing mask 6 on the face and then breathes evenly. The breathing detection system detects the patient's breathing frequency, exhalation and inhalation volume, and the corresponding time, and after feeding back the detection data to the dosage release system for learning, the required amount of medicine is automatically distributed to each inhalation process, so that the patient can release the medicine into the patient's body with the inhaled air during each inhalation, and automatically stop after the medicine is absorbed. It can automatically administer the medicine according to the patient's breathing habits and control the administration speed to ensure that the patient absorbs the medicine in one go, avoid drug waste, and improve the treatment effect. At the same time, the breathing conditions of the patient before each medication are recorded, so as to judge the treatment effect after medication. It can also be used as a long-term detection treatment to check the curve data collection of the patient's recovery status, so as to improve lung symptoms through medication treatment. The machine is used to compare data through the breathing volume, reduce the number of visits to the hospital for CT and MRI, reduce radiation to patients, and reduce the economic burden on patients.

[0041] Specifically, during inhalation, outside air enters from the first one-way valve 17, enters the breathing tube 5, and then enters the oral cavity through the third one-way valve 22, and then enters the lungs. During the inhalation process, the second mass flow meter 18 detects the amount of air inhaled, and the connected timer records the inhalation time. During exhalation, the second one-way valve 21 blocks the exhaled gas, so that the exhaled gas can completely enter the exhaust pipe 19 and be discharged from the second one-way valve 21. During the exhalation process, the third mass flow meter 20 detects the flow rate of the exhaled gas, and at the same time records the time used for exhalation through the connected timer, and the learning module automatically learns and records the patient's breathing habits. After the learning is completed, the medication is administered.

[0042] During drug administration, when the patient inhales, the inner surface of the breathing mask 6 is circumferentially provided with sensing contacts, and each sensing contact is a pressure sensor. When each pressure sensor is subjected to pressure, it proves that the patient's face fits the breathing mask 6, thereby ensuring that the patient's face fits the breathing mask 6, avoiding loose contact, resulting in incomplete absorption, causing drug waste, and being detrimental to treatment. At the same time, when the second mass flow meter 18 detects the entry of external air, the dosage release system is triggered to operate, doubly ensuring that the patient inhales completely, avoiding the patient being away from the breathing mask 6 and causing incomplete absorption. Then the timing module enables the drug administration control mechanism 8 to operate, triggering the drug administration tank 11 to administer the drug, and the electromagnetic Valve 15 controls the drug administration speed and cooperates with the first mass flow meter 14 to detect the drug administration amount, thereby ensuring that the drug administration amount can be completely absorbed by the patient during the patient's inhalation time, avoiding excessive amount, waste and overdose, and limiting the drug administration time node to be within the patient's inhalation time period, ensuring that the drug is administered during the patient's inhalation process, and the patient's exhaled gas is discharged from the exhaust pipe 19. After the first mass flow meter 14 detects that the drug administration set value is reached, the drug administration control mechanism 8 stops running, closes the drug administration tank 11, and stops drug administration, so that the patient can be accurately administered the drug, avoiding overdose and waste of drugs, and allowing the patient to maintain a stable drug intake pattern during the treatment course, thereby ensuring the treatment effect.

[0043] It also includes an operating system, which includes a power supply module, an operating module and a storage module. The power supply module is connected to the operating module, and the operating module is connected to the storage module. The power supply module is a battery, the operating module is a control screen 7, and the storage module is connected to the respiratory detection system and the dose release system.

[0044] The operating system also includes a remote control module, a medical interface operation module and a patient interface operation module.

[0045] The control panel 7 is installed on the outer surface of one side of the housing 1 , and the inner side of the control panel 7 is connected to a storage battery installed in the housing 1 .

[0046] During specific implementation, the battery can power the entire device to ensure that each power module can operate stably, and the control screen 7 is easy for patients or doctors to operate, and it is convenient to retrieve patient user information and respiratory information from the storage module, so that it is more convenient to observe the patient's breathing changes after taking medicine for a certain period of time, thereby determining the treatment effect during the period.

[0047] Specifically, doctors can enter the medical interface operation module of the equipment through the remote control module, so that they can view the patient's medication information and the respiratory change data during each medication learning, so that they can directly observe the patient's treatment effect remotely, and provide doctors with clinical data solutions through long-term detection data, improve doctors' diagnosis of various types of patient diseases and clinical research, and supervise whether patients follow standard operations and complete treatment plans. At the same time, they can change the medication plan according to the patient's treatment effect and reset the dosage once, so as to further improve the treatment effect, and reduce the number of times patients go to the hospital for CT and MRI, reduce radiation to patients, and reduce the economic burden on patients. The patient interface operation module can facilitate patients to query their own medication data and understand their own treatment effects, but cannot change the medication plan to ensure that patients can take medication according to the doctor's instructions.

[0048] A plurality of fixing seats 12 are installed inside the top box 3 , and the plurality of fixing seats 12 are commonly connected to the breathing tube 5 .

[0049] In a specific implementation, the breathing tube 5 is supported and fixed by the fixing seat 12, so that the installation firmness of the breathing tube 5 can be improved and shaking can be avoided, thereby avoiding affecting the detection accuracy of each flow meter.

[0050] A third one-way air valve 22 is installed on the breathing tube 5 , and the third one-way air valve 22 is arranged on one side of the air outlet pipe 19 .

[0051] In specific implementation, the third one-way valve 22 is provided to prevent the gas exhaled by the patient from entering the breathing tube 5. At the same time, it is convenient for the third mass flow meter 20 to detect the patient's exhalation condition, thereby improving the detection accuracy.

[0052] The medicine spraying pipe 13 is arranged between the third one-way air valve 22 and the air inlet pipe 16 , and a solenoid valve 15 is installed on the medicine spraying pipe 13 .

[0053] In specific implementation, the electromagnetic valve 15 can be used to control the speed at which the medicine spraying tube 13 sprays the medicine, thereby avoiding spraying too much medicine, which would result in the patient not being able to fully absorb the medicine in one inhalation, thereby avoiding medicine waste.

[0054] The medication control mechanism 8 includes a lifting plate 801, a fixed groove 802 and an electric push rod 803. The lifting plate 801 is slidably connected to the guide rod 9. A fixed groove 802 is provided in the middle of the lifting plate 801. Electric push rods 803 are installed on both sides of the fixed groove 802. One end of each electric push rod 803 is connected to the inner wall of the outer shell 1.

[0055] In specific implementation, the lifting plate 801 can be raised and lowered by extending and retracting the two electric push rods 803, so that the tank body 1101 can be squeezed when the lifting plate 801 rises, so that the dose release valve 1102 opens, thereby performing autonomous drug administration. During the drug administration process, the contraction of the electric push rod 803 cooperates with the patient's inhalation process, and when the electric push rod 803 is extended and reset, it cooperates with the patient's exhalation process, while ensuring that the dose release valve 1102 is in a closed state at this time.

[0056] When changing the medicine or replacing the medication tank 11, first open the top box 3, operate the control screen 7 to extend the electric push rod 803 in the medication control mechanism 8, so that the distance between the fixed groove 802 and the positioning block 10 is lengthened, so that the original medication tank 11 can be taken out and then replaced with a new medication tank 11. The operation is simple and convenient, so that different medicines can be used.

[0057] The medication tank 11 includes a tank body 1101 and a dosage release valve 1102 , and the dosage release valve 1102 is installed on the top of the tank body 1101 .

[0058] During specific implementation, the drug in the medication canister 11 can be discharged by triggering the dose release valve 1102 .

[0059] The positioning block 10 includes a shell 1001 , which is mounted on the inner wall of the housing 1 . A positioning groove 1002 is provided inside the shell 1001 , and a hole groove 1003 communicating with the spray pipe 13 is provided in the middle of the positioning groove 1002 .

[0060] The bottom end of the tank body 1101 is inserted into the fixing groove 802 , and the end of the dosage release valve 1102 is inserted into the hole groove 1003 .
