This specification discloses a dose verification method, apparatus, storage medium, and electronic device, relating to the field of radiotherapy technology. It can acquire target distance, equipment distance, detector convolution kernel, CT correction factor, detector dose data, and irradiation distances at multiple dose accumulation points. Based on the dose data at each coordinate point and the detector scattering convolution kernel, the initial deposited dose corresponding to each target point is determined. Then, based on the equipment distance, target distance, and the initial deposited dose at each coordinate point, the output beam intensity of the radiation device is determined. Based on the output beam intensity, initial deposited dose, equipment distance, CT correction factor, and irradiation distances at multiple dose accumulation points, the dose distribution at each dose accumulation point is determined. Finally, the dose distribution is compared and verified with the planned dose distribution. It is evident that the dose verification process considers the influence of various factors such as radiation device performance and detector position, thus improving the accuracy of dose verification.

Multi-dose preservative-free ocular fluid delivery devices are provided. The fluid delivery device includes a fluid dispensing system and a fluid package for storing a liquid in the fluid package and supplying the liquid to the dispensing system. The dispensing system includes an elongated chamber including a check valve defining an anterior closure of the chamber. The valve is normally closed and hermetically seals the chamber. The dispenser includes a vibrating motor that causes oscillation of the chamber and the fluid within the chamber. The oscillation of the chamber imparts momentum to the fluid stored in the chamber, which in turn imparts force to cyclically open the valve to dispense a stream or liquid droplets. Fluid is only dispensed when the motor is oscillating, otherwise the valve is hermetically closed.

The application provides a kind of based on graphics processor's proton dose distribution determination method and device, can be applied to medical radiation dose calculation technical field.The method comprises: calculating the respective pen beam trajectory of multiple pen beams;Obtain the respective dose kernel parameter of pen beam at multiple intersection points;According to field dose cutoff radius, determine the voxel of interest from the tissue voxel in the tissue voxel grid, wherein the field dose cutoff radius represents the upper limit value of the action distance of all pen beams under one field that significantly contributes to dose distribution in the transverse direction;Based on the respective dose kernel parameter of multiple intersection points, call multiple threads and execute multiple dose calculation tasks of voxel of interest in parallel, obtain the voxel deposition dose of voxel of interest;According to the respective voxel deposition dose of multiple voxel of interest, determine the dose distribution result related to specified tissue.

The present technology relates to multi-dose injection pens, pharmaceutical compositions of leuprolide and combinations thereof. The multi-dose injection pens may be configured to contain multiple doses of leuprolide and to administer a single dose of leuprolide.

A manual multi-dose auto-injector structured to manually dispense multiple discrete doses of a drug is provided with a hollow housing having at least a first housing end and a second housing end. An at least partially compressible vial is disposed in the housing and contains multiple doses of the drug. The vial is in mechanical communication with both housing ends. Each housing end has a needle spring-biasedly disposed in an unactivated configuration and disposed at least partially protruding from the housing end in an activated configuration. Each needle is manually selectively in fluid communication with the vial. Pressing a housing end against a user's body causes its respective needle to move from the unactivated configuration to the activated configuration and compresses the vial to dispense a dose of the drug. Each end / needle operates independent of the other. Post-injection, each needle is locked within the housing.
