Embodiment 1

[0030] A medical injector comprises a syringe 1, and the inner barrel cavity of the syringe 1 is a cylindrical cavity. An injection push rod 2 is arranged in the injection cylinder 1, and a rubber stopper 3 is installed on the end of the injection push rod 2. The shape of the rubber stopper 3 is also cylindrical. The outer wall of the plug 3 is against the inner wall of the syringe 1 for sealing. An injection needle 4 is installed at the end of the syringe 1 , and the injection needle 4 communicates with the inner cylinder cavity of the syringe 1 .

[0031] An installation groove 5 is provided on the inner cylinder wall of the injection cylinder 1, and a first liquid storage bag 6 is installed in the installation groove 5. Magnesium sulfate solution is housed in the first liquid storage bag 6, and the first liquid storage bag 6 can be made of plastic material , and the first liquid storage bag 6 can be squeezed by an external force to cause rupture. A slide plate 15 is also ...

Embodiment 2

[0035] Embodiment 2: the usage method corresponding to the above embodiment 1.

[0036] (1) In normal use, the protective sleeve 11 will be removed from the injection needle 4, and the rubber stopper 3 at the end of the injection push rod 2 will move along the length of the injection barrel 1 by pulling the injection push rod 2 , the injection liquid to be injected will be drawn into the injection barrel 1 from the injection needle 4. At this time, the crushing spring 8 will be pressed, the crushing rod 9 will enter into the crushing groove 17, and the rolling body 10 will be in contact with the injection barrel. 1, the inner wall of the cylinder rolls against each other;

[0037] (2) After the above-mentioned medical syringe is used once;

[0038] Step 1: Put the protective cover 11 on the 4 injection needles;

[0039] Step 2: Rotate the push rod 14, the push rod 14 will push the second liquid storage bag 12 to move towards the needle point of the injection needle 4, the se...

Abstract

The invention provides a medical syringe. The medical syringe comprises an injection cylinder, and an injection push rod installed in the injection cylinder, wherein a rubber plug is installed at theterminal end of the injection push rod, the periphery of the rubber plug abuts against the inner cylinder wall of the injection cylinder, an injection needle is installed at the terminal end of the injection cylinder, the injection cylinder is provided with a mounting groove, a first liquid storage bag is installed in the mounting groove, the first liquid storage bag is filled with a magnesium sulfate solution, the injection push rod is provided with a crushing member, the crushing member is located near the rubber plug, the crushing member can be used for crushing the first liquid storage bag, the outside of the injection needle is sleeved with a protective sleeve, a second liquid storage bag is arranged in the protective sleeve, a barium hydroxide solution is filled in the second liquidstorage bag, a pushing member is installed on the protective sleeve, the pushing member penetrates through the protective sleeve, the second liquid storage bag is fixedly arranged on the protective sleeve, and the pushing member is used to push the second liquid storage bag to a needle tip of the injection needle. After the above operation, the possibility of secondary use of the medical syringe attached with the barium sulfate precipitation is greatly reduced.

Description

technical field [0001] The present invention relates to medical appliances, in particular, to a medical injector. Background technique [0002] Medical syringes usually include a syringe and an injection push rod installed in the syringe. A rubber stopper is installed at the end of the injection push rod. The periphery of the rubber stopper is in conflict with the inner wall of the syringe. ; By pushing and pulling the syringe, the injection can be sucked into the syringe or ejected from the injection needle. [0003] Medical syringes are disposable medical devices. After one injection, they need to be recycled and destroyed in a standardized manner; but in the current market, the used medical syringes are simply washed and then reused, which still cannot reduce the violation of medical syringes. Possibility of secondary use. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a medical syringe, which can greatly reduce ...
