Description

Insulin needle safety removal and improvement device

The present invention relates to a safety needle removal device, in particular to an insulin needle safety removal device. The design of the insulin needle safety removal device is improved, so that the user can move the needle without the hand being close to the needle. Safely remove and recycle, to achieve safe needle application and reduce the risk of needle sticking between patients and medical staff.

At present, the insulin pen needle has three types of long-acting drugs, short-acting drugs, and mixed drugs according to the needs of patients. Each insulin drug contains 300u units/3ml of drug, and the injection content is adjusted according to the doctor's dose. The insulin needle is used with a sterile needle each time insulin is used. General operation step 1: tear the insulin packaging aluminum foil paper and insert the needle into the insulin injection pen rubber soft plug. Step 2: Rotate the insulin pen needle and the needle. Step 3: Unplug the needle and adjust the dosage of the doctor's prescription. Step 4: Select the injection site, which can be injected into the abdomen, thighs, arms, and buttocks. Operation step 5: After the injection of the drug is completed, the needle is prepared to be removed, and the transparent outer cover is first combined with the injection needle, and the needle is most easily pinned at this time.

According to the survey, nearly 70% of medical staff in medical institutions have had needle-sticking incidents. Currently used syringes are divided into general type syringes and insulin pen injectors. The construction of the needle retrieval devices of the two different types of syringes is completely different, and the medical staff must unload the needles by hand or leave the needles on the syringes, causing accidental needle sticks.

Clinically, when the nursing staff recovers the pen-type syringe needle (such as the pen-type insulin needle), the needle stick still occupies a certain proportion, because the pen-type syringe needle is double-layered, the needle is short, and the hands are in close contact during use. The needle is prone to needle sticking hazards. Among them, the eyes of the elderly are degraded, the elderly hand is easy to shake or the blindness of the patient with blindness and diabetic retinopathy is often pinched when the transparent cover is covered; or the caregiver is easily accidentally pinned when the transparent cover is covered Therefore, the nursing staff refuses to use this insulin needle, so that the nursing staff can choose to use the traditional insulin empty needle as the action of taking the medicine in order to protect themselves and prevent the two hands from returning the needle.

In addition, if the needle is stored in the recycling container, and the needle is to be recycled to the disposal barrel, the needle is accidentally pinched when the needle is taken out of the recovery container, which also causes the needle stick accident to occur.

In view of this, the author of this creation is the result of years of experience in this business, which has led to the research of the engine. After continuous research and experimentation, Yan Mengsheng has improved an improved device for safe removal of insulin needles. It is expected that the improved insulin needles will be safely unloaded. In addition to the design of the improved device, the elderly and medical staff can be easily used and the risk of needle sticking can be reduced.

The detailed features and advantages of the present invention are described in detail below in the embodiments, which are sufficient to enable any skilled artisan to understand the technical contents of the present invention and implement it according to the contents, the scope of the patent application and the drawings. Anyone familiar with the relevant art can easily understand the purpose and advantages of this creation.

The present invention provides an improved device for safely removing insulin needles, comprising a needle container having a needle insertion hole at an upper end and a needle withdrawal hole at a lower end, the needle insertion hole being provided with an opening inwardly from the opening The inclined surface and the extending groove extending from the inclined surface to the withdrawal hole, and The needle insertion hole may be provided with a plurality of protrusions protruding on the inclined surface; wherein, after the injection of the medicine is finished, the insulin injection pen and the stylus are inserted into the needle insertion hole, so that the insulin injection pen and the stylus are The transparent outer cover is disposed, the transparent outer cover is located in the needle insertion hole, and is closely engaged with the inclined surface of the needle insertion hole, and each of the protrusions is clamped on the upper end of the transparent outer cover, and the stylus is removed Separating from the insulin injection pen, the insulin injection pen is pulled out, and the protruding portion of the lower end of the transparent outer cover is exposed to the withdrawal hole, and the transparent outer cover is pressed from the needle into the hole to be recovered and recovered. Discard the bucket.
