Ressort à force variable dans un dispositif d'administration de médicaments

la source:Précision Qianye temps:2022-9-14

Devices for automatically delivering drugs, such as automatic syringes, are known as convenient and safe means of protection for patients to manage different drugs themselves. For safety reasons, many devices for delivering drugs include covers and other devices that protect users before and after use, such as injection needles.

Different devices for transporting drugs are different in their overall design settings. They all have a mechanism for automatically transferring the contents of pre filled and pre filled containers, and there is no need to manually force the contents of the containers into the patient through the transmission components, namely needles and nozzles.

Automatic delivery mechanisms in devices used to deliver drugs usually include compression coil springs. The challenge in the design of such springs is to balance the need for sufficient force at the end of the stroke and the need for less force during storage that will overload other parts of the device (when the spring is fully compressed).

  The problems caused by conventional coil springs in drug delivery devices can be overcome by variable force springs. A novel device for delivering drugs, which includes an elastic member (60), a driving mechanism (50), a holding mechanism (40) and a starting mechanism, the driving mechanism has one end connected to a stop and a second end operably connected to the elastic member, the holding mechanism is used to loosely hold the driving mechanism in the first position, where in the elastic member has accumulated energy, The starting mechanism is operably connected to the holding mechanism for releasing the driving mechanism to the second position when actively operated by the user, so that the accumulated energy is transmitted to the driving mechanism to drive the stop a predetermined distance in the container.

  Thus, the drug in the container is transmitted, which is characterized in that the elastic member is a variable force spring, which is suitable for generating a predetermined sequence of at least two different force characteristics during drug transmission.

  The variable force spring can break through the influence of Hooke’s law on the traditional spring, so that the stroke and force are no longer increased in equal proportion, but can achieve various elastic displacement combinations such as negative slope stepped fixed force. According to the needs of mechanical engineering, the relationship between elastic force and displacement stroke can be used to design various elastic curve changes in specific applications.

Shenzhen Qianye Precision Metal Co., Ltd. is a global spring manufacturer with more than 20 years of spring manufacturing experience. As a professional spring supplier, we can provide all kinds of spring springs, as well as the application design and solutions of all kinds of springs. We sincerely suggest that customers obtain consulting services from our R&D engineers at the initial stage of product introduction and development.
