Embodiment Construction

[0018] specific implementation plan

[0019] In the figure, the present invention includes a gun body, a propulsion system and an ejection system. Gun body is made up of propelling cylinder 1, positioning sleeve 2, trigger 11 and percussion device, gun handle 13. The positioning sleeve 2 is connected with the push cylinder 1 through a rotating screw thread to realize accurate positioning of the puncture depth. The firing device is made up of leaf spring 3, claw 5, bearing pin 10. The trigger 11 cooperates with the firing device to complete the actions of locking, driving and unlocking, so that the propulsion system can provide enough power to inject the trocar into the bone marrow cavity. The propulsion system is made up of altogether 5 parts of advancing spring 9, location card shoot 14, pull bar 15, limit card shoot 16, pull bar handle 17. The safety device is constituted by the positioning snap shoot 14 and the limit snap shoot 16 to ensure safe operation. The ejection ...

Abstract

The invention aims to provide a marrow liquid-injecting gun for rescuing, which is suitable for emergently setting up a transfusion channel in the field conditions including various accidents, such as, earthquake, fire hazard, traffic accident, and the like, as well as the natural disaster environment. The marrow liquid-injecting gun comprises a gun body, a propulsion system and an ejection system, wherein the gun body consists of a propulsion cylinder, a locating sleeve, a trigger and cocking device and a pikestaff; the propulsion system consists of a pull bar, a pull bar handle, a locating card shoot, a limiting card shoot and a propulsion spring; the ejection system consists of an internal pin, an external pin, an injection needle fixed device and a cartridge. In the invention, the materials of the main parts are mainly low carbon alloy steels after undergoing surface treatment. The invention is a medical apparatus universally used by the army and common people, is completely mechanical without any energy source requirement, has safe, convenient and fast use, can be repeatedly used for many times, greatly reduces the use cost of the original medical apparatus and has wide application prospect in clinic.

Description

technical field [0001] The invention relates to a medical device, which is a bone marrow injection gun suitable for emergency establishment of transfusion channels under field conditions (including various accidents and natural disasters such as earthquakes, fires, and traffic accidents) and used for rescue. Background of the invention [0002] At present, in most clinical first aid processes, especially for critically ill patients, the establishment of intravenous infusion channels and timely administration can win valuable time for rescue. However, due to dehydration, shock, hemorrhage and other reasons, there are often some critically ill patients who cannot quickly and effectively establish intravenous access, lose the best timing of administration, and fail to rescue. In this case, the key to rescue is to ensure timely administration of rescue drugs and fluids by establishing a channel to the marrow cavity in a very short time. [0003] The principle of establishing th...
