Description of the invention: [Technical field of the invention] The present invention relates to a syringe structure, and more particularly to a technical field of medical equipment, which has convenient operation, partial abandonment and economy. Semi-disposable syringe tube for efficiency. [Prior Art] According to the conventional anesthetic injection syringe, as shown in Fig. 1, 1 is mainly composed of a handle push rod, and the syringe 90 has a phased connection of 10 tow. The syringe 93' the first syringe 92 is in phase with the pusher grip 91, and the handle = the handle 91 is rotatable on one side to expose the volume of the first syringe 92: a dose of the tube 94 is inserted (eg An anesthetic agent, and the second syringe 93=3 has a needle joint 93. The needle joint 931 can be provided with a double-headed double-headed internal needle extending into the second syringe 93. The external needle of the double-ended needle is used for the human body device: 2: the syringe 90 of the conventional anesthetic injection syringe is used in conjunction with the current medical #stainless steel cylinder, and this is A kind of stainless steel syringe is made of two;::weight=cannot be discarded after it's. Therefore, it is usually required after use. ::Use, once the disinfection is not complete enough, it will cause the infection of the bacteria so that the needle of the front end of the syringe is a double-headed needle, usually in the syringe, and the Xiaogu head must first be from the stainless steel syringe. When the front end is removed and then the stainless steel personnel are removed, it is often - accidentally, that is, it is easy to stab the medical service, and it will also cause infection of the bacteria. After that, it will be treated: the syringe will be injected. All components are made of plastic and used first. This method can solve the risk of repeated use of the needle. 1302464 323-052TWP-5/28, but it is not economical, and the medical plastics are used and discarded.

The actuating groove 51 includes a longitudinal first actuating groove 511 and a second stopping groove 512 on the side of the first actuating groove 511. A locking groove 513 is formed in the rear end of the actuating groove 10 511 and corresponds to the block 147. The locking groove 513 is used to lock the card 147 after the syringe device 10 is used. A stop member 515 is further disposed between the stop groove 513 and the first actuating groove 511. The rear end of the first actuating groove 511 is further provided with an inner groove extending forward from the inner rear bottom end of the needle safety sleeve 5 514, so that the introduction block 147 enters the rear end of the first actuation groove 511 % 丨5. The combination of the needle safety sleeve 50 and the second cylinder 14 is inserted into the top of the insertion inner groove 514 by the clamping block 147, and then the force is applied to generate relative rotation to cause the block 147 to be inserted into the first portion. A lower end of the actuating groove 511, as shown in FIG. 10, the needle safety sleeve 50 and the second barrel 14 are combined, and the safety sleeve 50 of the needle 20 can protect the second barrel 14 The needle hub 144 is protected from exposure. Referring to FIG. 11, when the needle is to be used for injection, the needle safety sleeve 50 is pulled backward to cause relative displacement with the second cylinder 14, and the block 147 is locked to the first. In the front end of the actuating slot 511, that is, the block 147 can be 323-052TWP-11/28 1302464 _ at the front end along the first actuating slot 511, so that the needle seat 144 and the double-ended needle 146 protrude from the needle condom The opening 5 of the front end of the tube 5 can be used for injection. Referring to Figures 12-13, when the injection is completed, a slight force is applied to pull the needle safety cover 5 forward to make a relative displacement with the second cylinder 14, and force the card block 147 to further pass. The blocking member 515 is locked in the locking groove 513. That is, the locking block 147 can no longer be moved into the first operating slot 511, so that the double-ended needle 146 can be locked by the needle safety sleeve 50 and can no longer be Used to prevent the double-ended needle 146 from being used twice. At this time, the first cylinder 12 and the second cylinder η can be disassembled and separated, and the second cylinder 14 is used by the double-headed needle 146 and the medicine tube. The 40-phase is connected and closed by the needle safety sleeve 50, and the disposal of the part of the equipment can be performed, as shown in Fig. 13, to prevent the needle from being used twice after being cleaned; and the first cylinder 12 The combination of the handle 20 and the pushing mechanism 3 can be continuously reused as described in the first embodiment to meet the economics of the use of the device and to avoid environmental problems. Therefore, the present invention utilizes the syringe device to be separable and combined with the first cylinder and the second cylinder, so that the used syringe device can be conveniently and safely divided into two types which can be discarded and reusable. In part, the risk of avoiding the waste of the entire syringe and the risk of repeated use of the needle can be achieved at the same time, and the best design that combines economical 20 environmental protection and environmental protection is actively achieved. In summary, the present invention is indeed a rather excellent invention, and the invention is filed according to the law; however, the above description is only for the preferred embodiment of the present invention, and is extended by the technical means of the present invention. Variations are also intended to fall within the scope of the patent application of the present application.
