Abstract
The utility model provides a safe transfusion needle. The safe transfusion needle comprises a metal needle head; a guide tube which is matched with the metal needle head is sleeved in the metal needle head; the front end of the guide tube is blunt; the rear parts of the metal needle head and the guide tube are provided with a first handle and a second handle respectively; the rear end of the metal needle head is provided with a guide slot which is parallel to the metal needle head; the second handle extends out of the guide slot; when the second handle slides to the front end of the guide slot, the front end of the guide tube extends out of the tip of the metal needle head; during acupuncture treatment, the second handle slides to ensure that the front end of the guide tube is hidden in the metal needle head; during transfusion, the second handle slides to ensure that the front end of the guide tube is protruded out of the tip of the metal needle head, and the front end of the guide tube is very blunt, so even if the metal needle head and the guide tube contact a vascular wall, the vascular wall cannot be punctured easily; and therefore, the phenomenon of needle running in the transfusion process can be avoided.
Description
Technical field
This utility model relates to a kind of transfusion needle of transfusion device, relates in particular to a kind of safe infusion pin.
Background technology
The transfusion needle of transfusion device is normally metal and sharper keen; If the patient punctures blood vessel wall appearance race pin, string pin phenomenon once the moving transfusion needle that might cause gently in infusion process; Thereby cause and run pin place edema that the transfusion of having an acupuncture treatment again of having to has increased patient's misery.
The utility model content
The purpose of this utility model is to provide a kind of safe infusion pin that runs pin, string pin that in infusion process, is not prone to.
For achieving the above object; This utility model provides be with close-fitting with it conduit in the said metal needle of metal needle a kind of comprising; The front end of said conduit is blunt; The rear portion of said metal needle and said conduit is respectively equipped with first handle and second handle, has the leading groove parallel with said metal needle in the rear end of said metal needle, and said second handle stretches out said leading groove; When said second handle slided to the front end of said leading groove, the front end of said conduit stretched out the tip of said metal needle.
The safe infusion pin of this utility model; The length of the said metal needle between the tip of said first handle and said metal needle is less than the length of the said conduit between the front end of said second handle and said conduit; Said first handle is positioned at a side of the front end of said leading groove; When said second handle moved to the front end of said leading groove, said first handle overlapped with said second handle, with convenient said first handle and said second handle was fixed together.
The safe infusion pin of this utility model, said first handle and said second handle are flat.
Be with close-fitting with it conduit in the metal needle of the safe infusion pin of this utility model; The front end of this conduit is more blunt, through the second handle in the slip leading groove front end of conduit is hidden in the metal needle during acupuncture treatment, pinches first handle simultaneously with hands then and second handle is had an acupuncture treatment; Acupuncture treatment pinches first handle after finishing and second handle is pushed into gently the front end of leading groove; Make the front end of conduit stretch out metal needle, at this moment, the tip of metal needle is then on the tube wall attached to conduit; Then first handle and second handle are fixed; Slight moving arranged as the patient like this in infusion process, because the tip of metal needle is then on the tube wall attached to conduit, and the front end of conduit is more blunt; Even metal needle and conduit touch blood vessel wall and also be not easy it is punctured, thereby the race pin in the infusion process, string pin phenomenon have been avoided.

Fig. 1 looks cutaway view for the master of the safe infusion pin of this utility model;
Fig. 2 looks cutaway view for the master of safe infusion pin under transfusion state of this utility model;
Fig. 3 is the A-A sectional drawing of Fig. 2.
The specific embodiment
Be described in detail below in conjunction with the specific embodiment of accompanying drawing this utility model:
With reference to figure 1, Fig. 2 and Fig. 3; The safe infusion pin of this utility model comprises metal needle 1; Be with close-fitting with it conduit 2 in the metal needle 1, conduit 2 can slide in metal needle 1, and metal needle 1 forms piston cylinder operator with conduit 2; The rear portion of metal needle 1 and conduit 2 one respectively is shaped on the first handle 11 and second handle 22 of flat; The length of the metal needle 1 between the tip 12 of first handle 11 and metal needle 1 is less than the length of the conduit 2 between the front end 21 of second handle 22 and conduit 2, has the leading groove 13 parallel with metal needle 1 in the rear end of metal needle 1, and second handle 22 stretches out leading groove 13; Wherein, first handle 11 is positioned at a side of the front end of leading groove 13.When second handle 22 front end 21 of conduit 2 when leading groove 13 moves to certain position backward is hidden in the metal needle, when second handle 22 when leading groove 13 slides into the front end of leading groove 13 forward, the front end 21 of conduit 2 stretches out from the tip 12 of metal needle 1.
During use, the rear end of this conduit is connected with the tube for transfusion of transfusion device, through the second handle in the slip leading groove front end of conduit is hidden in the metal needle during acupuncture treatment; Pinch first handle simultaneously with hands then and second handle is had an acupuncture treatment, pinch first handle after acupuncture treatment finishes and second handle is pushed into the front end of leading groove gently, make the front end of conduit stretch out metal needle; At this moment, the tip of metal needle is then on the tube wall attached to conduit, and first handle overlaps with second handle; Then first handle and second handle are fixed; Slight moving arranged as the patient like this in infusion process, because the tip of metal needle is then on the tube wall attached to conduit, and the front end of conduit is more blunt; Even metal needle and conduit touch blood vessel wall and also be not easy it is punctured, thereby the race pin in the infusion process, string pin phenomenon have been avoided.
Embodiment recited above describes the preferred implementation of this utility model; Be not that scope to this utility model limits; Design under the spiritual prerequisite not breaking away from this utility model; Various distortion and improvement that the common engineers and technicians in this area make this utility model technical scheme all should fall in the protection domain that claims of this utility model confirm.
