ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention herein relates to an improved structure syringe needle cover that does not involve the utilization of a removable syringe needle cover, but can be safely re-covered after injection administering, thereby preventing accidental user needlestick injury and pathogenic transmission due to blood contamination and, furthermore, ensuring the safety of both medical treatment and refuse disposal personnel as well as greater overall safe performance.
2. Description of the Prior Art
In addition to the medical treatment procedure of oral ingestion, injection is a common means of delivering medication or nutritional supplements into the human body.
The hypodermic syringe is often utilized to inject medication and, as indicated in
FIG. 1
, the syringe needle must be covered to prevent needlestick injuries to the user. When the syringe needle is utilized to administer an injection, the syringe needle cover is pulled off before utilization and then placed back onto the syringe needle after usage. Although the conventional injection syringe needle cover facilitates the capping of the syringe needle and, furthermore, complies with safety measures, during the removal of the syringe needle cover, since the attention of the user is usually directed to the afflicted patient, needlestick injury is likely to occur, especially when the syringe needle cover is re-capped, which then results in harmful blood contamination from transmissible diseases such as hepatitis-A, hepatitis-B and HIV, etc. Furthermore, when the conventional injection syringe needle cover is removed, the placement design of the syringe needle cover readily results in the falling off and misplacement of the syringe needle cover. Moreover, the new-type safety syringes currently being researched and developed by manufacturers are specialized structures, many of these new safety syringes being incompatible with each other and unusable with conventional syringes or so structurally complicated that the high production cost results in wasted medical treatment resources.
In view of the said shortcomings and inconveniences, the inventor of the present invention conducted extensive research to address the drawbacks based on the spirit of innovative pursuit, professional experience, and specialized knowledge to develop an improved structure syringe needle cover that complies with existing safety standards and, furthermore, is compatible with conventional injection syringe needles as well as with a wide range of new-type safety syringes to increase the applicable extent of utilization, which includes intravenous drip syringes and other hypodermic medical treatment devices, without requiring modifications to the original capping fixtures to further enhance the practical value of the invention herein.
SUMMARY OF THE INVENTION
The primary objective of the invention herein is to provide an improved structure syringe needle cover that is installed over a syringe needle and has a protective head at the upper section with a minute hole disposed through it and, furthermore, a press release section situated along the two exterior sides of the protective head, with a hollow expandable and contractible space having a number of break lines along the two sides extending through its center section; formed in the lower section is a passage that is aligned with the minute hole of the upper section and which has an annular groove disposed around the exterior and, furthermore, there is a conjoinment section at the two sides of the annular groove; a coil spring is installed into the center section of the sleeve and a mount is then attached to the lower section of the said sleeve, with latch tabs extending from its two sides engaged to the center section of the sleeve and, furthermore, there is a catch section at the lower end of the latch tabs that engages the conjoinment section at the lower section of the sleeve; when the user utilizes the syringe needle, the mount is first rotated 90 degrees counter-clockwise to engage the starting end of the conjoinment section at the lower section of the sleeve to the catch section of the mount, then the press release section of the mount is pulled downward, at which time the syringe needle is extended through the minute hole disposed in the protective head of the sleeve and the latch tabs are engaged against the press release section, without requiring the removal of the syringe needle cover for utilization; when the injection is completed, the mount is rotated clockwise and after a coil spring returns to its original position in the sleeve, the catch section of the mount becomes locked onto the conjoinment section at the lower section of the sleeve such that the center section cannot be bent or broken, keeping the syringe needle from becoming exposed and thereby ensuring the safety of medical treatment personnel and achieving greater safe performance in that a syringe needle equipped with the invention herein can only be utilized once.
To enable a further understanding of the functions, structure, and innovations of the invention herein by the examination committee, the brief description of the drawing below are followed by the detailed description of the preferred embodiments.
