New description: [New technical field] This creation is about a safe blood collection needle, especially one that can automatically hide the needle after use and has comprehensive safety protection users, and has not used it. A rotary safety needle that contacts the needle. '[Prior Art] - Press, in today's general medical inspection process, it is necessary to frequently use injection or invasive blood collection devices. For example, in order to effectively control the blood sugar concentration of diabetic patients, medical personnel must use the blood collection device to stab every day. The patient's skin is used to collect a blood sample, and the blood sample taken is dropped on the test piece, and the test piece is inserted into the blood glucose meter to read the blood glucose concentration of the blood sample. Similar to the writing device, the needle is used to puncture the patient's skin and contact with the patient's blood, so the disease is transmitted through the blood through the needle (such as AIDS, type B, hepatitis C, etc. up to 20 kinds). Can not be ignored, and the traditional blood collection needle is either a traditional needle, or a vacuum blood collection needle, etc. φ After the use of the contaminated needle tip is exposed, it is easy to cause needle stick injury, no. Protection of medical personnel safety . Therefore, how to deal with the lack of operation of the conventional blood collection needle, to ensure the safety of the relevant personnel in use, to avoid the user accidentally contact with the used needle, or deliberate repeated use, it is the industry or The intellectuals should further think and try to break through the important issues. [New content] In view of this, this creation is to provide a rotary safety needle that automatically contacts the needle and the used needle after use. Relative rotation A+ The rotary safety needle of this creation is attached to a set of rear sleeves; the movable ', can be equipped with a needle holder and a bullet*; current, moving, and simultaneously squeezing the cartridge The axial position of the needle seat is opposite to the direction of the rear sleeve, and the needle seat is fixed to the needle seat to fix the needle seat to the rear; the direction of the perforation of the elastic tube is matched with the direction of the perforation: the spring is turned toward the front sleeve by the elastic crystal and the: : Exactly::: head ^ The purpose of the anti-purpose can be wrapped around the needle of the needle seat - the protective cover, the name of the cover is placed in the direction of the needle seat facing the needle seat axially from the sleeve The needle is formed - shielded and passed. The presence of the tamper cover is used to quickly identify whether the needle has been used or not. Another purpose of this creation is the whole set of rotary safety:::= After the front and rear sleeves of the group, the elastic two = free extension state, and the convex portion of the needle seat stays in the axial groove = Limiting the relative rotation of the front and rear sleeves to avoid being deliberately heavy [Embodiment] The characteristics of this creation can be clearly understood by referring to the detailed description of the drawings and the embodiments. As shown in the figure and the second figure, the rotary safety needle of the present invention comprises: a set of front sleeve 1〇 and a rear sleeve 2〇, a needle seat 3〇, and a second bomb 4 M377204 spring 40; Wherein: the 刖 sleeve 10 and the rear sleeve 20 are sleeved and rotatable relative to each other, the front sleeve 10 is provided with a through hole 13 at the front end for the needle 31 to enter and exit; the front and rear sleeves 10, 20 The inner wall is respectively provided with at least one axial groove 11 and 21 which can be opposite to each other, and at least one spiral groove 12, 22 is respectively provided, and the spiral grooves 12 and 22 of the front and rear sleeves 10 and 20 are end-ends. Engaged with the axial grooves 11, 21, and at the junction of the spiral groove 22 of the rear sleeve 20 and the axial groove 21, a pressing opening 23 for spirally penetrating the wall of the cylinder is provided. The needle holder 30 is installed in the front and rear sleeves 1〇 and 2〇 of the set, and has a needle head 31′ at the front end thereof and a protective cover 32 outside the needle head 31. One end of the protective cover 32 is opposite. Extending the perforation 13 of the front sleeve 1 , and the width of the shroud 32 relative to the front sleeve 1G is larger than the perforation 13; the outer wall of the needle holder is provided with an elastic pressing button 33 for the pressing opening 23 Forming a latching action, and relatively retracting into the spiral groove 22 and the axial groove 21 of the rear sleeve 20, the outer wall of the needle seat is further provided with at least one convex portion 34 for relatively extending into the front sleeve 1螺旋The spiral groove π. As for the 'spring 40' is disposed between the front and rear sleeves 1 〇, 2 巧 between the rear sleeve 20 and the needle holder 30, the two fixed ties of the spring 4 分别 are respectively The rear sleeve 20 and the needle holder 30 are fixed to each other, and when the force is not applied, the needle 31 of the needle holder 30 is hidden in the front and the inside of the group. j As shown in the third figure, the rotary safety needle 2 of this creation has two front and back sleeves (four) and _ pairs of rotations, and the needles 12 are guided by the needles of the needles. The money is axially displaced relative to the rear sleeve in the direction of 20, and simultaneously squeezes the spring 4 〇 to push the spring 仞 needle holder 30 toward the front sleeve 1 ,, the opposite direction of the needle holder 3 ^ 5 M377204 barrel 20 At the same time as the displacement, the shield 32 is automatically detached due to the inability to pass through the perforations 13. As shown in the fourth figure, when the front and rear sleeves 1 and 2 are relatively rotated until the elastic button 33 reaches the junction of the spiral groove 22 and the axial groove 21, the elastic button 33 is pressed and pressed. 23 is configured to hold the needle holder 3〇 behind, and to rotate the elastic ink 33 and the at least one convex portion 34 with the rear sleeve 2〇 and the axial groove 21 of the front sleeve 10 11 pairs. Then, after the through hole 13 of the sleeve 1 is facing the use portion, the elastic button 33 can be pressed as shown in the fifth figure to release the restriction on the needle holder 30. As shown in the sixth figure, the needle holder is replaced by a spring. 30 instantaneously ejects in the direction of the perforation 13 of the front sleeve 1 , so that the needle 31 protrudes relative to the perforation 13 of the front sleeve 10 and penetrates into the use portion, and when the spring 4 〇 returns to the unstressed free state, as shown in the seventh figure The needle holder 30 and the needle 31 are pulled back to ensure that the needle 31 is hidden inside the set of the rear and rear sleeves 10, 20 without being in contact with the used needle 31. In addition, the distance between the spiral grooves in the front and rear sleeves may be adjusted to adjust the elastic force and the puncture force of the integral rotary safety needle. As shown in the eighth figure, each spiral groove 12 may be The distance between the 22s is increased to increase the relative rotation path of the front and rear sleeves 10, 20, and the pressing spring 4 〇 generates a large compressive elastic force, so that the needle 31 can have a larger puncture force when used; The pressing port 23 can also be a spiral groove of adjustable elastic depth, as shown in the ninth figure, and increase the path length of the spiral grooves 12 and 22 in the front and rear sleeves.
