Abstract
The utility model provides a novel syringe, which relates to the technical field of medical care appliances. The novel syringe comprises a needle cylinder (1), a syringe needle (2), a pintle (3), a piston (4) and a push rod (5), wherein the upper part of the needle cylinder (1) is provided with the pintle (3), the upper part of the pintle (3) is provided with the syringe needle (2), the piston (4) is arranged inside the needle cylinder (1) and is arranged at one end of the push rod (5), the other end of the push rod (5) is exposed outside the needle cylinder (1), an small hole (6) is formed in the middle part of the piston (4), the diameter of the small hole (6) is 0.1mm, in addition, the small hole (6) is provided with a sealing film (7), the sealing film (7) is in a pressure type, the two side edges of the sealing film (7) are in butt joint, and the sealing film (7) is made of medical grade materials. The novel syringe has the advantages that the structure is simple, the operation is convenient, medicine can be completely injected into the body of a patient, and medicine waste and unnecessary medical disputes caused by incomplete injection are avoided.
Description
Technical field:
This utility model relates to technical field of medical instruments, is specifically related to a kind of drug injector.
Background technology:
In nursery work, for patient has an injection, be the most usual thing, but the progress along with medical level, the introducing of foreign drugs, some specific aim is more intense, the instructions for use of import drugs is extremely accurate, requirement for these medicines patient is also extremely harsh, do not allow a surplus medicine (because some will only have several milliliters of zero points), this has brought great difficulty to nursery work, and therefore nursing dispute occurs often.
Utility model content:
The purpose of this utility model is to provide novel injector, and it is simple in structure, easy to operate, medicine can be pushed in patient body completely, has avoided the drug waste that therefore causes and unnecessary medical care dispute.
In order to solve the existing problem of background technology, this utility model is by the following technical solutions: it comprises syringe 1, syringe needle 2, pintle 3, piston 4, push rod 5, the top of syringe 1 is provided with pintle 3, the top of pintle 3 is provided with syringe needle 2, the inside of syringe 1 is provided with piston 4, piston 4 is arranged on one end of push rod 5, the other end of push rod 5 is exposed at syringe 1 outside, the middle part of piston 4 is provided with aperture 6, aperture 6 diameters are 0.1 millimeter and closing membrane 7 are installed, and closing membrane 7 is for pressure-type, both sides of the edge docking and made by medical grade material.
This utility model in use, in piston 4, pack normal saline into, for patient, have an injection or medicine injection after, in the time of together with piston 4 is attached to syringe front end, thumb gives certain pressure again, normal saline in piston 4 flows into pintle 3 through small holes 6, thereby medicine is pushed in patient body completely.The amount of piston 4 interior normal saline is placed not commensurability according to the syringe of different size, but saline volume is the summation that syringe needle 2 adds pintle 3 positions.
The beneficial effects of the utility model:
1, applied widely, can be used for the syringe of all size.
2, easy to operate.
3, medicine can be expelled in patient body completely, not waste medicine.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of piston 4.
The specific embodiment:
Referring to Fig. 1 and Fig. 2, this specific embodiment is by the following technical solutions: it comprises syringe 1, syringe needle 2, pintle 3, piston 4, push rod 5, the top of syringe 1 is provided with pintle 3, the top of pintle 3 is provided with syringe needle 2, the inside of syringe 1 is provided with piston 4, piston 4 is arranged on one end of push rod 5, the other end of push rod 5 is exposed at syringe 1 outside, the middle part of piston 4 is provided with aperture 6, aperture 6 diameters are 0.1 millimeter and closing membrane 7 are installed, and closing membrane 7 is for pressure-type, both sides of the edge docking and made by medical grade material.
This specific embodiment in use, in piston 4, pack normal saline into, for patient, have an injection or medicine injection after, in the time of together with piston 4 is attached to syringe front end, thumb gives certain pressure again, normal saline in piston 4 flows into pintle 3 through small holes 6, thereby medicine is pushed in patient body completely.The amount of piston 4 interior normal saline is placed not commensurability according to the syringe of different size, but saline volume is the summation that syringe needle 2 adds pintle 3 positions.
The beneficial effect of this specific embodiment: it is simple in structure, easy to operate, medicine can be pushed in patient body completely, avoided the drug waste that therefore causes and unnecessary medical care dispute.
