AI Technical Summary

Technical Problem

Some users have difficulty keeping the syringe device's needle cap in place during medication dispensing, resulting in pain, discomfort, wetting of the injection site, premature removal of the device, and/or partial delivery of medication.

Method used

A braking mechanism is introduced into the syringe device, including a flexible arm and mating parts. The braking mechanism engages when the needle cover is in the holding position, providing resistance to prevent the needle cover from moving toward the first position, reducing the user's holding force requirements.

Benefits of technology

This reduces the force required for users to hold the device in place for dispensing medication, improving the ease of use and safety of the device.

Abstract

注射器装置由用户抵抗弹簧(204)的力保持在保持位置,以使药剂从装置分配。该装置具有针罩(213,613,713),该针罩可轴向移动以覆盖和露出针(217)。针罩(213,613,713)被弹簧204轴向偏置以覆盖针。针罩(213,613,713)可从针罩覆盖针的第一位置移动到用于分配药剂的保持位置。装置具有制动机构(231,331,431,531,631,731),该制动机构在针罩(213,613,713)处于保持位置时接合。制动机构施加阻力,该阻力阻止针罩(213,613,713)朝向第一位置移动。阻力小于弹簧施加的力。
