Problems solved by technology

These syringes need to be operated by a medical practitioner to inject the drug into the patient's body through the syringe, but it is difficult for the patient to operate independently
[0003] Some diseases require patients to take regular injections of drugs or products every day. Since the injected person cannot complete the injection by himself, he needs to go to the hospital every day to be assisted by medical staff, which wastes a lot of medical resources and a lot of time for the injected person.
[0004] Patent document CN103182115A discloses a plunger for a retractable syringe including a retractable needle, the plunger including a plunger capable of engaging the retractable needle, a retractable syringe and a method of assembling the same a rod, a plunger rim, a control member connected to the plunger rod, and a spring, wherein the plunger rod, the plunger rim and the control member cooperate to releasably maintain the spring in an initially compressed state , but the syringe still needs the assistance of medical staff during the injection, wasting a lot of time

Embodiment 1

[0071] The invention provides a syringe, such as Figure 1 to Figure 5 As shown, it includes a supporting shell 1, an injection assembly, a first locking assembly, a first elastic body 2 and a first liquid reservoir 9, and the first elastic body 2 and the injection assembly are installed on the supporting shell 1 Above, the injection assembly can extract medical fluid under the drive of human-driven mode or electromechanical drive mode, and can discharge the medical fluid extracted from the injection assembly under the drive of the first elastic body 2 and the injection assembly itself.

[0072] Further, the first elastic body 2 is preferably a spring, the injection assembly includes a cylinder 3, a first piston 4 and an injection head 5, and the cylinder 3, the first locking assembly and the first liquid reservoir 9 are installed On the support shell 1 and the cylinder body 3 can move relative to the support shell 1 . The injection head 5 is mounted on the barrel 3, the barr...

Embodiment 2

[0090] This embodiment is a preferred example of Embodiment 1. In this example, if Figure 6 ~ Figure 10 As shown, a second locking assembly is also included, and the second locking assembly includes a second rolling body 38, a third elastic body 39, a blocking member 40, a second locking housing 44 and a first driving body. The second locking housing 44 is installed on the support frame 19, and a second wedge-shaped space is formed between the third connecting rod 17 and the second locking housing 44, and the second wedge-shaped space is sequentially along the first direction. The third elastic body 39, the second rolling body 38, and the blocking member 40 are arranged, and the width of the second wedge-shaped space gradually becomes smaller. A fourth elastic body 41 is arranged between the support frame 19 and the second connecting rod 16 and the second Four elastic bodies 41 are sleeved on the third connecting rod 17, and the second connecting rod 16 is provided with a fo...

Abstract

The invention provides an injector and an injection platform. The injector comprises a supporting shell, a first elastic body and an injection assembly. The first elastic body and the injection assembly are both installed on the supporting shell, and the injection assembly can be driven by a manual driving mode or an electromechanical driving mode to extract liquid medicine and can be driven by the first elastic body and the injection assembly to discharge the liquid medicine extracted from the injection assembly. The injector is easy to operate and convenient to use, an injected person can conduct injection work by himself / herself, medical resources are saved, the time of the injected person is saved, the structural design of switching of all states of a barrel is ingenious, the whole injector is made of conventional parts, the price is low, universality is good, and the requirement for disposable use can be met.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a syringe and an injection platform. Background technique [0002] There are currently several models of manually activated syringes on the market for the injection of pharmaceutical solutions, suspensions, vaccines, medications, and other liquid medications. These syringes need to be operated by medical practitioners to inject the medicine into the patient's body through the syringe, but it is difficult for the patient to operate independently. [0003] Some diseases require patients to take regular injections of drugs or products every day. Since the injected person cannot complete the injection by himself, he needs to go to the hospital every day to be assisted by medical staff, which wastes a lot of medical resources and a lot of time for the injected person. . [0004] Patent document CN103182115A discloses a plunger for a retractable syringe comprising a retractable needle,...
