Problems solved by technology

Although this method of medication can greatly improve the local treatment effect of patients, because each person has different inhalation capacity and different methods, the delivery dose of this drug delivery device is relatively low. Delivered dose and lung deposition rate are strongly dependent on the patient's inspiratory rate, with lower collision energies, lower flow rates, and lower delivered dose and lung deposition rate
[0003] The dry powder inhaler in the prior art is not equipped with components that can monitor the inspiratory flow rate, and the size of the inspiratory flow rate depends entirely on the patient's feeling. Although there are doctors' instructions and training whistles to help patients find the feeling in the initial use, it still Depending on the patient's subjective feeling, th

[0032] Specific implementation case 1:

[0033] A dry powder inhaler housing capable of detecting the inhalation flow rate includes: an irregular semi-elliptical inhaler housing body 1, an integrated housing cavity 11 is provided above the inhaler housing body 1, and the upper end of the housing cavity 11 passes The dust cover 2 with the same shape as the accommodating cavity 11 is sealed. The dust cover 2 encloses the accommodating cavity 11 as a accommodating space for built-in electronic components. A circuit board 3 is installed in the accommodating cavity 11, and a battery is integrated on the circuit board 3 The fixing base 31, the power supply 32 installed in the battery fixing base 31, the pressure sensor 33, the circuit switch 34, the microcontroller unit MCU 35 (not shown in the figure), and the signal transceiver 36 (not shown in the figure), of which, The integrated installed power consumption components are electrically connected to the power source 32, the circuit s...

Example

[0040] The present invention relates to a dry powder inhaler housing capable of detecting the inhalation flow rate by adding a housing cavity 11 and an integrated circuit board 3 in the housing cavity 11 to the inhaler housing in the prior art, and installing a pressure sensor 33 on the circuit board. The patient's inhalation flow rate is detected in time and displayed on the display device, so that the patient can adjust the inspiratory flow rate in time according to the information on the display device. The position sensor, direction sensor, and LED light are set to further improve the detectable items of the dry powder inhaler housing In addition, ensuring the visibility of the patient to the detection item facilitates the patient to adjust the use operation in time according to the detection unlocking, and ensures that the patient can correctly use the dry powder inhaler installed with the dry powder inhaler shell. On the other hand, the correct use of dry powder inhalers b...

Abstract

The invention provides a dry powder inhaler shell capable of detecting the flow rate of medicine inhaling. The shell comprises an inhaler shell body in the prior art, a containing cavity for installing an integrated circuit board is additionally arranged on the inhaler shell body, and a pressure sensor is installed on the circuit board and used for detecting the inhaling flow speed of a patient inreal time and displaying the flow speed on display equipment so that the patient can adjust the inhaling flow speed in real time according to the information on the display equipment. A position sensor, a direction sensor, a buzzer and an LED lamp are additionally arranged, so that detection items of the dry powder inhaler shell are further improved, visibility of the patient on the detection items is ensured, the patient can conveniently adjust application and operations in real time according to detection results, and it is guaranteed that the patient can correctly use a dry powder inhalerprovided with the dry powder inhaler shell. The shell of the dry powder inhaler is directly replaced, so that the patient conveniently uses the dry powder inhaler shell, it can be ensured that the patient takes a sufficient quantity of medicine for controlling or healing diseases, and the conflicts between doctors and patients are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dry powder inhaler casing and a dry powder inhaler capable of detecting the drug inhalation flow rate. Background technique [0002] The dry powder inhaler, as a pulmonary drug delivery device, relies on the patient's deep breath to inhale the drug powder in the device into the lungs. During the inhalation process, the effective drug powder (API) and the carrier (mostly lactose) are driven by the inhaled airflow, resulting in particles and The collision between particles or the collision between particles and the surface of the device further separates the effective drug powder from the carrier. The carrier has a relatively large particle size and is deposited in the oropharynx. After being separated from the carrier, the effective drug powder with an aerodynamic particle size of less than 5um can reach The lungs play a healing role. Although this method of medication ...
