Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, is (environmental condition that comprises various accidents such as earthquake, fire, vehicle accident and natural disaster) urgent transfusion path of setting up under a kind of suitable field condition, the marrow liquid-injecting gun that is used to rescue.
Background of invention
At present, in the most clinical emergency treatment process, when especially critical patient being rescued, set up the venous transfusion passage, administration in time can try to gain time precious to one for rescue.But some critical illness patients are often arranged owing to reasons such as dehydration, shock, massive hemorrhage, can not set up vein fast and effectively when logical, lose best delivery time, rescue failure.In this case, through setting up the medullary cavity passage in the short time, guarantee that the medicine and the liquid of giving treatment in time are the keys of rescuing at the utmost point.
The principle of setting up the medullary cavity passage is to utilize medullary cavity to include abundant vasoganglion, communicates with blood circulation through capillary network, and therefore, medicine, liquid in the input medullary cavity can get into blood circulation rapidly, effectively.In the extremely short time, set up passage rapidly, and, comprise blood transfusion in medullary cavity as long as the medicine that the ability intravenous uses all can be used.Thereby be specially adapted to rescue the scene, can improve salvage success rate greatly.
Summary of the invention
The function of marrow liquid-injecting gun of the present invention is: in the shortest time, the safe and reliable outside passage that leads to interior bone pulp cavity body of a sclerotin of setting up reaches the purpose of setting up transfusion path, infusion first aid medicine.
For achieving the above object, the present invention includes rifle body, propulsion system and ejection system.The rifle body by advance tube, abutment sleeve, trigger and percussion lock, pikestaff totally 4 parts form.Abutment sleeve is connected through rotary threaded with advancing tube, realizes the accurate location of paracentesis depth.Percussion lock is formed by hitting pawl, sheet spring, bearing pin.Trigger cooperates the action of accomplishing locking, driving, release with percussion lock, makes propulsion system provide enough strength that trocar is injected medullary cavity inside.Propulsion system by pull bar, pull bar handle, location tenon, spacing tenon, propelling spring totally 5 parts form.Constitute safety by location tenon and spacing tenon, to guarantee safety operation.Ejection system by interior pin, outer pin, entry needle fixture, chuck totally 4 parts form.Outer pin is a hollow-core construction, and interior pin is a solid, is positioned at the cavity of outer pin.By interior pin, the trocar that outer pin is formed closely is connected with the entry needle fixture through chuck, and spacing tenon and abutment sleeve control trocar get into the degree of depth of medullary cavity.The main parts size material is main with surface treated low-carbon alloy steel.The present invention can let interior pin, the trocar that outer pin is formed get in the medullary cavity within several seconds, and pin in taking out can be realized urgent transfusion, work such as sample detecting through outer pin.
Major advantage of the present invention in sum has:
(1) the present invention is fit under the field condition (comprising under the environmental condition that various accidents such as earthquake, fire, vehicle accident and natural disaster cause) and sets up the transfusion path and be used for rescuing very much, is the universal medical apparatus and instruments of a kind of the army and the people of having.
(2) the present invention can be repeatedly used, and significantly reduces the use cost of original such medical apparatus and instruments, has wide practical use clinically.
(3) complete mechanical of the present invention does not have any energy requirement.
(4) the present invention is simple in structure, in light weight, portable, one hand can be operated, can keep somewhere for a long time in vivo, meets the medical requirement on the broad sense.
(5) the present invention is safe in utilization, convenient, fast.In case of emergency, can accurately locate paracentesis depth, can in the extremely short time, to the administration of sufferer place, reach the purpose of rescuing or treating, and wound surface be little, the risk of complication is lower.
