Abstract

The invention relates to a medical instrument which consists of a needle tube, pan head screws, a needle head, a pressure plate, a plate handle, a front protective cover, a plunger piston, a rear protective cover, a piston rod, a strip cover and other parts as well as liquid medicine. In the invention, various first-aid liquid medicines are preloaded into different needle tubes according to different dosage, wherein, the liquid medicine is closed by small balls at the root of the needle heads and the plunger pistons; and then the needle heads and the needle tubes, which are filled with the first-aid liquid, are closed in the protective covers under an aseptic condition. When necessary, the strip cover is torn off and the plate handle is rotated by fingers so that the needle heads rotate 90 degrees to be communicated with the needle tubes, and then injection can be performed. The first-aid needle of the invention is applicable to hospitals and other medical institutions for first aid of critical patients suffered from anaphylactic shock, penicillin anaphylaxis, cardiac arrest, sudden death, pesticide poisoning, carbon monoxide poisoning and the like.

Description

Emergency Needle

Technical field: the present invention relates to a kind of medical apparatus and instruments.

BACKGROUND: It is now critically ill patient emergency, is to come up with Ann Tou watts, then Ann Tou watt wheel cutting the neck, and then clamp the neck knocked Ann Tou tile, remove the needle, press the needle, insert the safety Tou watts, taking liquid, then injected complex action in this regard, prolonged delays in rescue time, hand wheel tile cutting and beating Ann Tou produce some glass particles contaminated liquid, harm people.

Summary of the invention: the present invention packs various first aid medicinal liquid in the various needle tubing according to different dosages in advance, and medicinal liquid is by the bead of syringe needle root and plunger sealing; Syringe needle, the needle tubing of emergency liquor of will packing into again is enclosed in the guard shield under aseptic condition together.Need the time spent, the rectangular lid of tearing is pointed the rotor plate handle simultaneously, makes syringe needle rotate 90 degree, and needle tubing and syringe needle are got through, i.e. injectable.

Solve the technical scheme that this technical problem adopts: on the rustless steel bead, bore an aperture, the syringe needle root embeds in the aperture of rustless steel bead, on the bead with aperture centrage vertical welding on two rotating shafts, vertical backstep welding upper plate handle in rotating shaft with syringe needle.Embed needle tubing front end boss with two block pressur plates, the syringe needle bead is put into two pressing plate spheres, direction is vertical with needle tubing, and the reuse screw is screwed into the needle tubing boss, and the needle tubing bead is compressed, and the pressing plate compressing degree can make the plate handle pull freely again can seal medicinal liquid.

The beneficial effect of this technical scheme is the shortcoming that has overcome trivial operations in the present rescue critical patient process, has striven for rescue time, simultaneously, has avoided liquid medicine contamination.

Description of drawings:

Fig. 1 is the structure of this Emergency Needle, draws together needle tubing 1, pan head screw 2, and syringe needle 3, joint 4, bead 5, pressing plate 6, plate handle 7, front protection cover 8, plunger 9, rear shield 10, piston rod 11, medicinal liquid 12 is formed with rectangular lid 13 parts such as grade.

Fig. 2 is a kind of needle assembly, by syringe needle 1, and locating piece 2, joint 3, stainless steel ball 4, rotating shaft 5 is formed.Be applicable to the Emergency Needle that dosage is bigger.

Fig. 3 is another kind of needle assembly, by syringe needle 1, and locating piece 2,, stainless steel ball 3, rotating shaft 4 is formed, and is applicable to the Emergency Needle that dosage is less.

Fig. 4 is a needle tubing, and the needle tubing front end has two boss, and boss center tapping is used for fixing two pressing plates 6, and annular boss is established at the needle tubing middle part, is used for locating with front protection cover.

Fig. 5 is a pressing plate, and two pressing plate front end spheres are used for fixing stainless steel ball, and sphere top aperture is used to the rotating shaft of packing into, the rear groove needle tubing boss of packing into.75 ° of arcwall faces are attached to the needle tubing head.

Fig. 6 is a rear shield, is made up of cylindrical shell and spheroid, and needle tubing and syringe needle are packed into behind the front protection cover, rear shield is bondd on the front protection cover, so that sealing.

Fig. 7 is a front protection cover, and Fig. 7-1 is a front view, and Fig. 7-2 is a left side view, Fig. 7-3 be A to view, aerofluxus was used when 4 apertures were had an injection; An oblong aperture is established in the front, so that syringe needle swing, needle tubing and syringe needle are packed into behind the front protection cover, rectangular lid 13 is bonded in front protection cover covers oblong aperture, so that seal.

Fig. 8 is rectangular lid, and two vee gutters of this rectangular lid compacting so that the time spent produces stress concentration, are torn easily.

The specific embodiment:

Embodiment 1, treatment penicillin anaphylaxis patient choose according to the doctor's advice dosage adrenergic Emergency Needle are housed, and the right hand is held needle body; Left hand thumb and forefinger pinch the external part of rectangular lid 13, the rectangular lid 13 of firmly tearing, and while left hand thumb is push pedal handle 7 forward; Syringe needle is stretched; It is subcutaneous then syringe needle to be lunged the patient, hand thumb together with the rear shield spheroid before push piston bar 11, it is subcutaneous that medicine juice is injected the patient; Repeat aforesaid operations as required again.

Embodiment 2, carbon monoxide poisoning patient get the Emergency Needle that 3 milligrams of lobelines are housed, and it is operated with embodiment 1.
