Embodiment Construction

[0053] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0054] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a syringe includes a container 1, an injection device and a power unit; the container 1 is provided with a through hole and a blind hole; the injection device fits in the through hole; the power unit fits in the blind hole middle.

[0055]The injection device is a modified ordinary disposable plastic syringe, which contains insulin medicine (about 1-2ml). The syringe puts the injection device and the power unit into the container 1, and connects the injection device and the power device through the container 1. , and drive the injection device to move through the power device to realize the injection process.

[0056] The power device includes a fluid container 2, a ...

Abstract

The invention discloses a syringe and relates to the field of medical instruments. The syringe includes an accommodating device, an injection device and a power device. The accommodating device is provided with a through hole and a blind hole; the injection device is placed in the through hole, and the power device is placed in the blind hole. The syringe is simple in structure, easy to process and manufacture, low in cost, simple to operate, convenient to use and has no noise influence, and the safety is ensured more easily. At present, a technology related to mechanical spring power is relatively mature at present, and it is easier to implement a power spring with stable design and manufacturing performance.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a syringe. Background technique [0002] Syringes have been used in medicine for more than 300 years. Traditional syringes have brought great convenience to the medical process from design to use in medical careers, especially for the treatment process of Western medicine. However, with the improvement of human technology and living standards, traditional syringes have gradually shown some problems and disadvantages, such as easy to cause a series of problems such as the spread of infectious diseases, needle infection, and needle contamination. The development of today's technology makes more and more syringes appear in people's field of vision, and have been successfully put into medical careers, such as disposable syringes, self-destructing syringes, spiral syringes, insulin pumps and so on. Disposable syringes are composed of a jacket, core rod, rubber stopper, taper, hand and...
