Injection training device with audio prompts

Abstract

The invention relates to an injection training device with sound prompting function, which comprises a shell with a first end and a second end; There are two sections of slide rails, and the starting end of each slide rail is formed with ribs extending axially along the shell; the rotating sleeve is movably sleeved on the inner sleeve, and the outer wall of the rotating sleeve is provided with a pushing part. The inner wall of the rotating sleeve is provided with a sliding part that can move along the slide rail. In the initial state, the sliding part abuts against the rib and is located on the opposite side of the slide rail; the protective cover can at least partially extend out of the housing, and the protective cover The sleeve is provided with a pushing part that matches the inclined surface of the pushing part; the first elastic part acts on the rotating sleeve to keep the rotating sleeve moving toward the first end of the housing; the second elastic part acts on the protective cover to keep the protective cover Tendency to extend out of the shell. The device has a simple structure, can emit sound and does not need manual reset.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and in particular relates to an injection training device with a sound prompt function. Background technique [0002] The most common way of administering the drug is by injection, eg intravenously, subcutaneously or intramuscularly, a syringe containing the drug is used for the injection, which is usually administered by trained healthcare personnel. In some cases, where regular injections of medication are required, it may be desirable for a patient or other individual to use a syringe to self-inject or give injections to other individuals, and devices for automatic injections have been developed to allow patients to self-inject. [0003] However, since patients are usually neither nurses nor educated in medical devices, such devices for automatic injection must prove to be simple and safe to use. In particular, it is important to ensure that with such devices a controlled dose of p...

Problems solved by technology

[0005] The disadvantages of this injection practice device are: 1. It needs to be manually reset by the mandrel, and the operation is cumbersome; 2. The sound effect is composed of one or more flexible arms that move with the plunger assembly relative to the axially fixed sounding track. produced

As the simulated injection process progresses, the flexible arm bounces over a row of longitudinal teeth, producing an audible "click", wherein each "click" preferably represents the expulsion of a unit metered simulated medicament, the sound The structure involves many parts, the structure is complex, and the failure rate is high
