The invention discloses an inhalation administration device and a design method, and mainly relates to the technical field of medical instruments. The device comprises a capsule base, a capsule body, a capsule cabin and a suction nozzle, an inner cavity of the suction nozzle is of an inverted trapezoid structure, and in other words, the diameter of the section is increased by 0.033 mm every time the inner area of the suction nozzle is raised by 1 mm from the bottom end to the top end. According to the design, by optimizing the internal flow field of the suction nozzle, the dispersity of medicine particles can be remarkably improved, wall surface deposition is reduced, and therefore the dispersity of the medicine particles and the lung deposition efficiency are improved. The invention also provides a design method based on lattice Boltzmann method-immersion boundary method-large eddy simulation multi-physics field coupling numerical simulation, and by setting specific performance evaluation parameters, the structure optimization of the inverted trapezoidal suction nozzle can be efficiently and accurately guided. An in-vitro deposition test shows that the performance of the device is superior to or equivalent to that of a commercially available product.

The present disclosure provides an inhalation drug auxiliary device, and relates to the technical field of medical devices, which solves the technical problem of requiring a large force to press the puncture part of an inhaler to break a capsule. The inhalation drug auxiliary device comprises a shell and an automatic breaking module, the shell is arranged outside the inhaler to fix the inhaler, and the automatic breaking module is arranged on the shell to automatically break the capsule placed in the inhaler. The automatic breaking module arranged on the shell automatically breaks the capsule in the inhaler, solving the technical problem of requiring a large force to press the puncture part of the inhaler to break the capsule, and the weak users have difficulty in pressing, which is not friendly to the old and young users.

An animal restraint device for inhalation drug administration comprises: a support frame consisting of multiple support legs and support plates at the top of the support legs; an animal restraint box mounted on the support plates for accommodating and restraining experimental animals; a head cover with a side opening closable to one side of the animal restraint box along its length; and a tray movably mounted on the support legs and located below the animal restraint box, the tray having sliding through holes corresponding to the support legs, the tray being slidably connected to the support legs through the sliding through holes; a support hole communicating with the sliding through hole and a fixing member disposed within the support hole on the side of the tray; a predetermined gap exists between the sliding through hole of the tray and the support leg to allow adjustment of the tray's horizontal angle by adjusting only the height of one side of the tray. This device can reduce pressure on the lungs and abdomen of large animals, improving the accuracy and stability of inhalation drug administration data for large animals.

This invention discloses a lyophilized exosome formulation of Liubao tea with low nebulization loss rate, its preparation method, and its application, relating to the fields of biomedicine and inhalation formulation technology. The active ingredient is Liubao tea exosomes, and it also contains a pharmaceutically acceptable lyophilization protectant. The lyophilized formulation, after reconstitution, is adapted to a mesh nebulizer for nebulization inhalation. The Liubao tea exosomes are extracted by the following method: Liubao tea leaves are washed, rapidly frozen and ground in liquid nitrogen, homogenized with buffer solution, and allowed to stand at low temperature. Then, they are subjected to gradient centrifugation, filtration clarification, and purification and enrichment using a microfluidic chip system. The microfluidic chip system is the Huixin Bio EXODUS fully automated exosome extraction system, which relies on sonication and eddy current coupling physical fields to achieve selective separation of exosomes. This invention prepares Liubao tea exosomes into a lyophilized formulation specifically for nebulization inhalation, expanding the application direction of exosomes from fermented tea plants in the field of respiratory inhalation drug delivery.

The invention belongs to the technical field of medical instruments, and discloses an inhalation administration device for respiration and critically ill medical departments, which comprises an administration bottle body and a medicine storage bottle body, the medicine storage bottle body contains liquid medicine required by inhalation administration, the administration bottle body is connected with a mask, a pressurizing assembly and a liquid drawing assembly, the pressurizing assembly comprises a box body and a driving part, and the driving part is connected with the box body. A pressurizing cavity is formed in the inner side of the box body, a pair of pressurizing gears are connected to the inner side of the pressurizing cavity, the liquid drawing assembly comprises a liquid drawing barrel and atomization equipment, the liquid drawing barrel is connected with a piston and a spring, and the mask communicates with a medicine guide pipe and an expiration pipe. The pressurizing assembly is used for pressurizing gas exhaled by a patient, the liquid drawing assembly is used for drawing liquid medicine needed by inhalation and administration, during expiration, the piston exhausts gas in the liquid drawing barrel, during inhalation, the piston moves reversely under the action of the spring to draw the liquid medicine, administration is achieved through the medicine guide pipe, the administration efficiency is high, and the administration effect is good.

The invention discloses an inhalation administration device, and relates to the technical field of medical auxiliary instruments. In order to solve the problems that an existing inhalation drug delivery device cannot monitor the real-time breathing state of a patient, drug waste is easily caused, and necessary safety is lacked, the inhalation drug delivery device comprises a mask, an atomizer and a breathing monitoring assembly, the atomizer is connected with the mask through a drug delivery pipeline, and the atomizer is connected with the mask through a drug delivery pipeline. The breathing monitoring assembly is connected with the mask through a breathing pipeline, and a control valve assembly is further arranged between the breathing monitoring assembly and the atomizer and used for blocking connection between the atomizer and the mask when a patient exhales; the respiration monitoring assembly can be adjusted in a self-adaptive mode according to the expiration intensity of the patient, and the expired gas is exhausted at different speeds. The breathing of a patient can be dynamically monitored, medicine waste can be avoided, and the use safety of the device is improved through the arrangement of self-use exhaust.
