Problems solved by technology

[0003] In order to overcome the shortcomings of compressed gas or spring-type long-distance launch syringes, which are similar in shape to military firearms, and the launch power is too large, which is easy to hurt animals, I invented a device for long-distance launch and injection of animals: special syringe Catapult, this device has accurate and effective long-distance ejection and injection capabilities, and this planting device has an open bow, the shape is quite different from military firearms, and medical operations in the field will not cause misunderstanding accidents

Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the special ejector for syringe is described further.

[0012] figure 1 It is a cross-sectional structure diagram of the middle part of the intersection surface of the bow-shaped frame and the catapult cylinder of the catapult specially used for syringes. figure 1 Among them, a syringe (5) is equipped with in the middle rear portion of a catapult (1), and the syringe (5) rear portion bears on the push rod (4), and an elastic string (3) is tied on the push rod (4). figure 1 The bow-shaped frame (2) and the catapult (1) are crossed and fixed, but the bow-shaped frame (2) does not pass through the catapult (1), and does not affect the smoothness of the catapult (1). The two opened ends of the bow-shaped frame (2) are connected with the elastic strings (3), and the elastic strings (3) are in a tense state, and the elasticity of the elastic strings (3) determines the ejection power of the whole catapult.

Abstract

The invention discloses an ejector special for an injector. The ejector for the injector is characterized by mainly comprising an ejection tube, a pushrod, a bowed frame, an elastic string, a finger lock triggering mechanism and a grab handle, wherein the pushrod is arranged in the ejection tube; a small section of half surface for assembling and disassembling the injector is arranged on the rear part of the ejection tube; a section groove penetrating through the two sides of the ejection tube is also formed in the middle part of the ejection tube; the bowed frame is crosswise and fixedly connected with the ejection tube; the finger lock triggering mechanism and the grab handle are also arranged on the rear part of the ejection tube.

Description

technical field [0001] The invention relates to an ejection device, in particular to an ejection device used for ejecting a syringe, and belongs to the technical field of medical devices. Background technique [0002] In the field of medical technology, it is often necessary to perform medical injections on some animals, but some animals are very fierce or agile, and always keep a long distance from humans. It is impossible or dangerous to use general hand-held injection methods. The catapult injection method is a method that people can inject medicinal liquid to animals from a long distance. At present, people have adopted a lot of long-distance launch syringe methods, and some use compressed gas guns as syringe launchers. The structure of this compressed gas gun is very complicated. Similar to military firearms, it is easy to cause misunderstandings when performing medical operations in the field, and this kind of gun is too powerful, which may cause harm to animals, and m...
