Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically a disposable buckle type safe insulin syringe needle.
Background
Diabetes is a group of metabolic diseases characterized by hyperglycemia. Hyperglycemia is caused by a defect in insulin secretion or an impaired biological action, or both. Hyperglycemia occurring in the long term of diabetes results in chronic damage to, and dysfunction of, various tissues, particularly the eyes, kidneys, heart, blood vessels, nerves.
With the development of economy, the number of diabetics is increasing, and daily household insulin self-injection is very frequent. An insulin pen is a common injection tool for insulin treatment at present, and is matched with an insulin needle to complete subcutaneous injection.
The utility model has the application number of CN201720383425.4 and is named as a novel utility model of an insulin needle outer needle cap, which belongs to medical injection instruments and comprises a cap body, an end cover and a clapboard, wherein the end cover is detachably arranged at the opening of the cap body, and the opening of the end cover is just opposite to the opening of the cap body; the partition board is inserted into the end cover along the radial direction of the end cover and close to the opening of the end cover, and is used for separating the insulin needle head placed in the cap body from the end cover. The utility model provides an insulin syringe needle outer needle cap, it installs an end cover additional on the cap body, has inserted the baffle on the end cover. After the insulin needle is arranged in the cap body, the end cover is fastened, the insulin needle and the end cover can be separated by the clapboard, and then the insulin needle can be stably placed in the cap body. When the syringe needle is used, the partition plate is firstly drawn out, the insulin syringe needle slides into the end cover, then the end cover is detached, the inner needle cap on the insulin syringe needle is pinched by the hand, the syringe needle can be taken out, the whole process is simple, convenient, safe and reliable, and the condition of pricking a patient can be completely avoided.
However, at present, the insulin needle purchased by the patient is usually placed in the outer needle cap, the outer needle cap is pulled out when the insulin needle is used, and the outer needle cap is sleeved back again after the insulin injection is finished and is rotated to be discarded. In hospital, the clinical staff is responsible for the injection and the nurse is familiar with the entire procedure specification, but still inevitably a puncture event occurs. When the family insulin is injected, the operation technique of a patient or family members is not standard, and in order to save cost, a needle head is repeatedly used and repeatedly sleeved for a part of patients, so that the acupuncture injury is more easily caused, and a disposable buckle type safety insulin needle head is designed.
