Description
Technical field
This utility model relates to a kind of syringe, particularly relates to a kind of Combined injector that injection is housed, belongs to technical field of medical instruments.
Background technology
Along with the development of medical field, conveniently clinical rescue patient or Emergency use in particular cases, occurred the device of medicine and syringe one in prior art, this device has simple to operate, greatly shorten administration time, and can the advantage of effectively decreasing pollution and error rate.
As, publication number is CN2069729U, name is called the utility model patent of " novel disposable syringe ", which disclose a kind of disposable medical syringe, this syringe has injection needle, syringe, propeller, the injection bottle that syringe is made by tubular telescopic element built with an agent structure, injection is accommodated in injection bottle.
And for example, publication number is CN1147325C, and the patent of invention that name is called " Cartrix ", which discloses a kind of Cartrix, comprises one and has an entry needle coupling part at far-end and have the cylinder of an opening at near-end; One has mouth and flexible hollow cylindrical body, and the tubular container of the plastics of the liquid medicine poured in advance is within it housed, and one by the opening of cylinder be inserted therein and the plunger of within it rest slidably.Tubular container rest is in cylinder, and therefore, the mouth of tubular container is placed in the intracavity of the entry needle coupling part of cylinder, and cylinder peels off from the inwall of cylinder and clamp-ons in the space between cylinder and plunger when time in plunger push in cylinder.
Syringe disclosed in above two sections of patent documentations, use as Cartrix, in use, by the component compresses of push rod by dress injection, medicine, after being squeezed, is injected in patient body, after fluid removal, a certain amount of air can be entered, cause in injection process, 1) injection speed inequality; 2) injection can not all inject in patient body, injection volume inaccuracy; 3) residual injection can only be communicated with syringe and together lose, and causes waste, cause certain pollution to environment to medicine.
Utility model content
The purpose of this utility model is to provide a kind of Combined injector that injection is housed, solve in the use procedure of pre-tank note syringe of the prior art, medicine can not very utilize, the drug waste caused and the problem of environmental pollution, this utility model has simple to operate, utilization ratio of drug is high, can not cause the advantage of environmental pollution.
This utility model is achieved through the following technical solutions:
A kind of Combined injector that injection is housed, it is characterized in that: comprise syringe, syringe needle, push rod and container cavity, described container cavity is located in syringe, described push rod one end is provided with handheld component, the other end is provided with rubber piston, and described rubber piston and push rod can slide in described container cavity; Described container cavity one end is provided with protruding opening, and described opening is provided with external screw thread, is provided with corresponding female thread in described syringe needle.
In order to realize this utility model better, described opening is provided with the seal cover being carried out by medicine in container cavity sealing, and is provided with the female thread corresponding with the external screw thread on opening in described seal cover.
The side of this utility model container cavity is provided with scale, installs medicine in advance, according to patient's practical situation, when not needing to use whole amounts, determines injection volume by scale.
Further, opening radius of the present utility model is 2 ~ 4mm, too small openings, is unfavorable for the loading of medicine and the injection of later stage medicine, and opening crosses the probability that conference improves drug contamination.
This utility model compared with prior art, has the following advantages and beneficial effect:
(1) this utility model is separately provided with container cavity in the syringe of ordinary syringe, can in advance medicine be loaded in container cavity, before using, container cavity is placed in syringe together with push rod, and syringe needle is fixed on the opening part of container cavity, finally by External Force Acting, by the infusion of medicine patient body in container cavity.Compared with the Cartrix of prior art, syringe accommodating chamber of the present utility model is along with the promotion of external force, be not subjected to displacement change, only that push rod and rubber piston advance to syringe needle direction, injection is injected in patient body, utilization ratio of drug is high, and has had the amount of medicine and control more accurately.
(2) this utility model container cavity opening is provided with seal cover, before injecting, by seal cover, the medicine in container cavity is sealed, prevent medicine contaminated, during use, change seal cover into syringe needle, and then inject, be particularly useful for the treatment that first aid or other special circumstances are carried out patient, have easy to use, fast, not easily there is the advantage of entanglement.
(3) side of container cavity of the present utility model is provided with scale, for installing medicine in advance, but according to patient's practical situation, when not needing to use whole amounts, determining injection volume, use more flexible by scale.
(4) container cavity of the present utility model and syringe are that isolation type is connected, and generally, medicine can not spill, and causes syringe contaminated, therefore syringe can be recycled again, improve stock utilization, alleviate the pollution of non-degradable material to environment; In order to fundamentally improve the utilization rate of material, the thickness of container cavity is little relative to the syringe thickness of ordinary syringe in prior art, can ensure to use, and syringe thickness of the present utility model is large compared with the thickness of container cavity, to improve the service life of syringe, thus fundamentally improve stock utilization, reduce the pollution of environment.
