Abstract

The utility model relates to a multi-function injection device for medical use, overcomes the operating procedure of repeatedly dismounting a needle head when a common injection device is used for puncture operation. The utility model is characterized in that the side surface of the front of the utility model is added with a nipple with is communicated with the inner cavity of utility model; the front of a hollow cylinder is provided with a faucet which controls the switch on and off of the two nipples; the faucet is rotated, which can make the two nipples are respectively in the state of switching on and off. The utility model has the advantages that an additional exhaust and suction channel is provided compared with an injection device because a nipple is added in the front; the utility model adopts a valve gate to simultaneously control two exhaust and suction channels, simplifying the operating program of puncture operation and shortening operating time.

Description

Multi-function injection device for medical use

This utility model belongs to a kind of medical apparatus, particularly a kind of medical multifunctional syringe.

At present, domestic hospital normally adopts ordinary syringe when doing various paracentesis.The front portion of ordinary syringe has only a nipple that is connected with syringe needle, when doing paracentesis, need with the forward nipple of syringe with have the syringe needle that is connected flexible pipe and be connected, carry out puncture procedure then, more or finish when needing flushing and injectable drug when the material of need suctions in suction, as pleurocentesis, liver abscess puncture, peritoneocentesis and serous cavity flushing and injectable drug art, need the material of suction more, and the ordinary syringe capacity is less, and after the empty tube of syringe was taken out completely, the flexible pipe that is connected that must be connected with syringe needle was clamped with mosquito forceps, again nipple is unloaded from connection tube, could discharge the material in the syringe, then, again with syringe nipple be connected flexible pipe and connect, decontroling mosquito forceps takes out again, so repeatedly, operate quite loaded down with trivial detailsly, use very inconvenient.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of medical multifunctional syringe simple to operate, easy to use is provided.

This utility model is the improvement of existing ordinary syringe, promptly on the basis of ordinary syringe, increase a nipple with its intracavity inter-connection in its forward side of empty tube, and in two cocks that nipple is switched on or switched off of the front portion of empty tube installation control, described cock is installed on the empty tube with jump ring.The rotation cock can make two nipples be the state of switching on and off respectively.

The utility model has the advantages that, owing to increased a nipple in its front portion, therefore, Duo a row than ordinary syringe and inhaled passage, and adopt valve simultaneously two rows to be inhaled passages and controlled, must unload the complex operations process of syringe needle when having avoided ordinary syringe to do paracentesis and flushing, injectable drug repeatedly, particularly for the bigger paracentesis of aspiration, can simplify paracentetic operation sequence greatly, shorten the operating time.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1;

Fig. 4 is the front view of this utility model jump ring.

As shown in drawings, this utility model has an empty tube 2, in empty tube 2, a piston that matches with it 1 is installed, is processed with a nipple 7 with its intracavity inter-connection in the front of empty tube 2, also be processed with a nipple 8 with its intracavity inter-connection in sky 2 a forward side; Front portion at empty tube 2 is equipped with cock 3, and cock 3 usefulness jump rings 6 are installed on the empty tube 2; In cock 3, be processed with the anastomosing through hole 3a of inner chamber and the through hole 3b that make nipple 7 and nipple 8 and empty tube 2, be decussation between the central axis of through hole 3a and through hole 3b; Knob 5 is installed on cock 3, the indication boss 5a of an identification through hole 3a and through hole 3b axis direction is arranged on the knob 5.During use, rotary knob 5, make indication boss 5a point to the place ahead or the rear of empty tube 2, at this moment, nipple 7 is connected with the inner chamber of empty tube 2, nipple 8 disconnects with the inner chamber of empty tube 2, after syringe needle thrusts the site of puncture, again nipple 7 is connected and can aspirates with the flexible pipe that is connected that has syringe needle, when empty tube 2 is taken out when full, as long as with knob 5 half-twists, make indication boss 5a point to the side of empty tube 2, at this moment, nipple 7 is closed in cock 3, nipple 8 is connected, and promoting piston 1 can discharge the material in the empty tube 2 through nipple 8; When needs flushing and injectable drug, can directly medicine be sucked from nipple 8, then, rotary knob 3 makes indication boss 5a point to the place ahead or the rear of empty tube 2, and then nipple 8 is closed, and nipple 7 is connected, and promotes piston 1 and just the medicine in the empty tube 2 can be injected in the body.

This utility model also can be used for the bigger intravenous injection of dose, and the preparation of quiet drops physic liquor etc.
