Problems solved by technology

[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 rinsed and then reused by the injection needles, which still cannot reduce the cost. Possibility of illegal secondary use of medical syringes

Embodiment 1

[0032] A medical injection assembly, comprising a syringe 1, an injection push rod 2 installed in the syringe 1, a rubber stopper 3 is installed at the end of the injection push rod 2, the shape of the syringe 1 is cylindrical, and the periphery of the rubber stopper 3 is in contact with the The inner cylinder wall of the injection cylinder 1 is in conflict with each other, the injection needle 4 is installed at the end of the injection cylinder 1 , and the injection push rod 2 can reciprocate and slide along the length direction of the injection cylinder 1 .

[0033] A mounting base 5 is also provided, and a mounting hole 7 is provided on the mounting base 5. The mounting hole 7 is used for the injection cylinder 1 and the injection needle 4 to be inserted together.

[0034] A first extruded piece 9 is slidably disposed in the mounting seat 5 . In this embodiment, the number of the first extruded piece 9 is two, and the two extruded pieces are arranged symmetrically around the...

Embodiment 2

[0045] Embodiment 2: The difference from Embodiment 1 is that the end of the second extruding member 16 can abut against the side of the injection needle 4, and the contact points of the second extruding member 16 and the injection needle 4 are in contact with the first The contact points of the extrusion part 9 and the injection needle 4 are different.

[0046] Specifically, one end of the second driving member 14 is detachably connected to the injection push rod 2, and the other end of the second driving member 14 is slidably connected in the second driving groove 15. The push-pull direction of the rod 2 is consistent; the second extruded part 16 is slidingly connected in the mounting seat 5, and the two ends of the second extruded part 16 are respectively the second extruded end 161 and the second driving end 162. The end 161 is used to abut against the side wall of the injection needle 4, the second driving end 162 is the second driving slope 17, the end of the second driv...

Abstract

The invention provides a medical injection component which comprises an injection cylinder, an injection push rod as well as a mounting base and a first driving part, wherein the injection push rod ismounted inside the injection cylinder; a rubber plug is mounted at an end part of the injection push rod; the circumference of the rubber plug abuts against the inner cylinder wall of the injection cylinder; an injection needle is mounted at an end part of the injection cylinder; a mounting hole is formed in the mounting base; the injection cylinder and the injection needle are both inserted intothe mounting hole; a hole part corresponding to the injection needle, of the mounting hole, is an extrusion hole section; a first extrusion part is arranged inside the mounting base in a sliding manner; one end of the first extrusion part is a first extrusion end; the other end of the first extrusion part is a first driving end; the first driving end is a first driving inclined surface; the firstdriving part is positioned on one side back away from the injection cylinder; a first driving groove is formed in the mounting base; the first driving part is connected with the first driving groovein a sliding manner; an end part back away from the injection cylinder, of the first driving part, protrudes outside the side wall of the mounting base; and an end part in the first driving groove, ofthe first driving part, abuts against the first driving inclined surface and is used for driving the first extrusion end of the first extrusion part to abut against and extrude the side wall of the injection needle. By adopting the medical injection component, the probability of secondary use of a medical injector can be greatly reduced.

Description

technical field [0001] The present invention relates to medical appliances, in particular to a medical injection assembly. 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 way; but in the current market, the used medical syringes are simply washed and then reused by the injection needles, which still cannot reduce the cost. Possibility of illegal secondary use of medical syringes. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a medical ...
