ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to a protecting cap structure for the needle of a syringe; and is especially to a device with an cylindrical extendible member and a foldable cover connected with each other, the device can fast obscure the needle to prevent it from accident stabbing, thus it is suitable to be a protecting cap structure or the like.
2. Description of the Prior Art
Since syringes were widely used, needles for syringes have been frequently inadvertently used to accidentally stab medical workers. Therefore, the modes of storage of needles have been always highly thought of; and various protecting structures for the needles of syringes have been developed.
However, most conventional protecting structures for the needles of syringes have a sleeve for each needle generally in the shape of an elongate cylinder having a receiving chamber with a predetermined longitudinal depth for insertion therein of the needle of the corresponding syringe; the elongate cylinder of the protecting sleeve is provided on the external surface thereof with a protective pick-up portion extending a predetermined length outwardly to allow a user to pick up with fingers, the protective pick-up portion has a predetermined distance from the external surface of the syringe to provide a safe distance when in picking up; however, with this safe distance from the syringe during picking up the protective pick-up portion by the user, the syringe still needs to be aligned with the sleeve for the needle for inserting after use to make obscuring of the needle. While in the procedure from taking the sleeve to slipping the needle of the syringe into the sleeve, it is still probable that cases of accident stabbing by the needle may occur; and more, after slipping connecting of the sleeve with the syringe, there is no stable connection between the two, this tends to have the chance that the sleeve drops; therefore, such conventional protecting structures still have the defect of inadvertence in using the needle to accidentally stab a person.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide a protecting cap structure for the needle of a syringe, wherein, by providing a device with an cylindrical extendible member and a foldable cover connected with each other, the present invention can envelop the needle and prevent the needle from accident stabbing and thereby can increase practicality as well as safety of the present invention.
Another object of the present invention is to provide a protecting cap structure for the needle of a syringe, wherein, the cylindrical extendible member can be compressed to fixedly engage with the cover for mutual positioning, so that medicine can be injected conveniently, and convenience as well as practicality of the present invention can be increased.
To get the above object, the present invention is provided with a protecting sleeve having a receiving space for receiving a needle; the protecting sleeve is comprised of a foldable cover and a cylindrical extendible member connected with each other. The cylindrical extendible member is a hollow cylinder, the shank thereof has a compression portion with a suitable length; a foldable portion is provided in neighboring to the compression portion. The cover is in the shape of a semi-cylinder, one end of the cover is connected with the cylindrical extendible member in order to combine with the cylindrical extendible member when the cover is folded to close to thereby envelop the needle. And thereby, the needle is fast obscured to prevent it from accident stabbing, and practicality as well as safety of the present invention can be increased.
The present invention will be apparent in its features and structure after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.
