Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a modified sodium hyaluronate gel device for injection. Background Art

[0002] Modified sodium hyaluronate gel can mainly achieve the functions of filling, retaining moisture and promoting collagen synthesis, so it is often used in medical work such as wound repair, depression filling and body shaping.

[0003] In the prior art, when using modified sodium hyaluronate gel to treat patients with cervicitis, it is necessary to use a syringe to inject the modified sodium hyaluronate gel into the patient's uterine cavity. During this process, the injection needle needs to be inserted into the vagina until it reaches the cervical opening. Since the insertion amplitude and force of the needle are difficult to accurately control, the traditional syringe needle has the potential safety hazard of damaging the patient's cervical opening and vaginal wall. For this reason, we propose an injectable modified sodium hyaluronate gel device. Utility Model Content
