Description

A kind of safety transfusion needle

Technical field

The utility model relates to a kind of medicine equipment of the use of infusing, and especially relates to a kind of safety transfusion needle.

Background technology

At present, the transfusion needle that medical field is conventional is made up of sheath, needle handle, needle tubing, flexible pipe and needle stand substantially. Medical personnel take out sheath, and transfusion needle punctures, and after completing, needle stand docking transfusion device starts transfusion. After having infused, extract transfusion needle, needle tubing is separated with flexible pipe, put into respectively the recovery utensil of appointment. But in medical personnel's use procedure, exposed transfusion needle very easily injures own or other personnel, causes infected.

Summary of the invention

The purpose of this utility model is to provide a kind of safety transfusion needle, and product, after finishing using, is pulled back transfusion needle, to the cylindrical shell of transfusion needle, and transfusion needle is stuck in cylindrical shell, transfusion needle can not be extracted from cylindrical shell two ends, prevent and reduced own or other people can not be wounded by stabbing.

The purpose of this utility model is achieved in that

A kind of safety transfusion needle, formed by sheath, double fins, cylindrical shell, flexible pipe, needle stand, needle tubing, needle handle, feature is: the outer wall middle part at cylindrical shell is provided with annular round and elastic boss, below the outer wall middle part of cylindrical shell, round and elastic boss, be provided with annular, outwardly open square groove, be provided with the Elastic buckle of vertical upward opening in the inwall bottom of cylindrical shell, be provided with the guide runner of two vertical symmetrical upward openings on the inwall top of cylindrical shell, be provided with the guide runner bottom surface of confined bed chute in the inwall middle and lower part of cylindrical shell; Be provided with the circular medicine liquid channel of up/down perforation in the centre of needle handle, be provided with the square elasticity boss of annular at the outer wall middle part of needle handle, the square elasticity boss of needle handle can slide into downwards in the square groove of cylindrical shell, both are relatively fixing, needle handle is locked in cylindrical shell, above the outer wall middle and upper part of needle handle, square elasticity boss, be provided with the flat position being used in conjunction with the Elastic buckle of cylindrical shell, the Elastic buckle of cylindrical shell can block the flat position of needle handle, needle handle is stopped mobile.

Above the outer wall top of needle handle, flat position, be provided with two guide ledges that are used in conjunction with the guide runner of cylindrical shell, the guide ledges of needle handle can be done vertical mobile in the guide runner of cylindrical shell.

The utility model is made up of sheath, double fins, cylindrical shell, flexible pipe, needle stand, needle tubing, needle handle, the round and elastic boss at cylinder body outer wall middle part can be pressed downwards, effect is that the square elasticity boss on needle handle is depressed, and can make needle handle move to flexible pipe direction while drawing flexible pipe. There is square groove cylindrical shell middle part, is mainly used in coordinating with the square elasticity boss of needle handle, prevents that needle handle from moving up and down. The double-edged Elastic buckle in cylinder inboard wall bottom, Main Function is that needle handle is fastened, and while ensureing transfusion, the square elasticity boss of needle handle is in the time that maloperation process is depressed, and needle handle is unlikely to move in cylindrical shell. Two vertical symmetrical guide runners on barrel wall top, the stroke while being pulled back for limiting needle handle. Needle handle is for the needle tubing of the transfusion needle that bonds, and there is circular medicine liquid channel centre, has square elasticity boss on outer surface simultaneously, and this square elasticity boss coordinates with the square groove of cylindrical shell. Be provided with two guide ledges on the outer wall top of needle handle, play guide effect when moving in cylindrical shell, determined distance mobile in cylindrical shell simultaneously.

The utility model in use, different with traditional medical infusion pin operation, exactly after product is finished using, pulls out stitching and suddenly have any different. Traditional infusion pin pulls out pin: hand-held needle handle exits needle tubing from blood vessel fast, and of the present utility modelly pull out stitching suddenly: the round and elastic boss on left hand applying light cylindrical shell, the right hand pinches the flexible pipe that connects needle handle, then the right hand moves to far-end fast, at this moment the needle tubing on needle handle has entered rapidly cylindrical shell, and be stuck in cylindrical shell, cannot expose outside cylindrical shell. Prevent that exposed transfusion needle from injuring own or other personnel, cause infected, thereby reached effect safely and effectively.

Therefore, the utlity model has and transfusion needle is pulled back to cylindrical shell and be stuck in cylindrical shell, make transfusion needle can not extract, prevent that from cylindrical shell two ends exposed transfusion needle from injuring own or other personnel, causing infected, advantage safely and effectively.

Detailed description of the invention

Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.

A kind of safety transfusion needle, by sheath 1, transfusion needle double fins 2, cylindrical shell 3, flexible pipe 4, needle stand 5, needle tubing 6, needle handle 7 forms, outer wall middle part at cylindrical shell 3 is provided with annular, the round and elastic boss 31 of good springiness, at the outer wall middle part of cylindrical shell 3, the below of round and elastic boss 31 is provided with annular, outwardly open square groove 32, be provided with the Elastic buckle 33 of vertical upward opening in the inwall bottom of cylindrical shell 3, be provided with the guide runner 34 of two vertical symmetrical upward openings on the inwall top of cylindrical shell 3, be provided with the guide runner bottom surface 35 of confined bed chute 34 in the inwall middle and lower part of cylindrical shell 3, be provided with the circular medicine liquid channel 74 of up/down perforation in the centre of needle handle 7, be provided with the square elasticity boss 71 of annular at the outer wall middle part of needle handle 7, the square elasticity boss 71 of needle handle 7 can slide into downwards in the square groove 32 of cylindrical shell 3, both are relatively fixing, needle handle 7 is locked in cylindrical shell 3, in the outer wall middle and upper part of needle handle 7, the top of square elasticity boss 71 is provided with the flat position 72 being used in conjunction with the Elastic buckle 33 of cylindrical shell 3, the Elastic buckle 33 of cylindrical shell 3 can block the flat position 22 of needle handle 7, needle handle 7 is stopped mobile, on the outer wall top of needle handle 7, the top of flat position 72 is provided with two guide ledges 73 that are used in conjunction with the guide runner 34 of cylindrical shell 3, the guide ledges 73 of needle handle 7 can be done vertical mobile in the guide runner of cylindrical shell 3 34.

Operation principle:

1, assembling: first assemble cylindrical shell 3 and needle handle 7, cylindrical shell 3 opening parts are aimed in one end large needle handle 7 diameters one end of two guide runners 34, and the guide ledges of needle handle 7 73 is aimed to the guide runner 34 of cylindrical shell 3.
