Abstract
The utility model provides an intravenous injector, includes cylinder and push rod, the syringe needle is fixed to the front end of cylinder, is equipped with the needle cap outside the syringe needle, the inner wall of cylinder is equipped with the screw thread, and the surface of push rod is equipped with the external screw thread that matches with the screw thread of cylinder, cylinder and push rod threaded connection, and the rear end of push rod is the caudal peduncle, is equipped with stop nut on the push rod, and stop nut's side is equipped with the screw, has the screw in the screw. The beneficial effects of the utility model are that: compare with prior art, cylinder and push rod screw -thread fit make the propulsion of medicine more steady, set up stop nut and screw, make the liquid medicine can not surpass the scheduled volume, so use the utility model discloses an intravenous injector can reach the purpose of control intravenous route speed and shot, can not bring danger for patient to can avoid the dispute of unnecessary doctors and patients. The utility model discloses an intravenous injector simple structure, convenient to use, market prospect is extensive.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates in particular to a kind of intravenous injector.
Background technology
Frequent employing intravenous medical treatment disease in hospital clinical treatment and nursery work at present, strictly controls injection amount and speed can not be too fast, otherwise can bring danger to patient, uses during common shot device intravenous injection and is not easy to control
Speed and injection amount, can bring danger to patient, causes unnecessary doctor-patient dispute.
Utility model content
The purpose of this utility model provides a kind of intravenous injector that can control intravenous speed and injection volume.
The technical solution of the utility model is specially:
A kind of intravenous injector, comprise syringe and push rod, the front end fixed needle of syringe, is provided with pin cap outside syringe needle, the inwall of described syringe is provided with screw thread, the outer surface of push rod is provided with the external screw thread mated with the screw thread of syringe, syringe is threaded with push rod, and the rear end of push rod is caudal peduncle, and push rod is provided with stop nut, the side of stop nut is provided with screw, has screw in screw.
Described push rod is provided with scale.
The beneficial effects of the utility model are: compared to the prior art, syringe and push rod threaded engagement, make the propelling of medicine more steady; Stop nut and screw are set, make medicinal liquid exceed scheduled volume, so use intravenous injector of the present utility model can reach the object controlling intravenous injection speed and injection volume, danger can not be brought to patient, thus unnecessary doctor-patient dispute can be avoided.Intravenous injector structure of the present utility model is simple, and easy to use, market prospect is extensive.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram of pin cap.
Detailed description of the invention
As shown in Figure 1, a kind of intravenous injector comprises syringe 3 and push rod 4, the front end fixed needle 2 of syringe 3, pin cap 1 is provided with outside syringe needle 2, the inwall of syringe 3 is provided with screw thread, and the outer surface of push rod 4 is provided with the external screw thread 41 mated with the screw thread of syringe 3, and syringe 3 is threaded with push rod 4.The rear end of push rod 4 is caudal peduncle 6, and push rod 4 is provided with stop nut 5, and the side of stop nut 5 is provided with screw 51, has screw (not drawing in screw figure) in screw 51.Push rod 4 is provided with scale, and this scale can be identical with the scale of syringe 3.
As shown in Figure 2, pin cap 2 comprises pin cap body 11, the upper end of described pin cap body 11 is provided with opening 12, described pin cap body 11 has the accommodating chamber holding syringe needle, described accommodating chamber is in communication with the outside by described opening 12, the outer wall of described pin cap body 11 is fixed with flank 13, the bottom outer surface of described pin cap body 11 is provided with sucker 15, described sucker 15 is connected with described pin cap body 11 by support bar 14, the material of described support bar 14 is rubber, the quantity of described flank 13 is two, two described flanks 13 are fixed for axis of symmetry is symmetrical with the axis of described pin cap body 11, the middle part be fixed on described pin cap body 11 length direction of two described flank 13 symmetries, the position that described flank 13 contacts with hands caves inward and forms press section, the shape of described press section is circular arc, the diameter of described press section is 1.3cm-1.7cm, the length that described flank 13 extends described pin cap body 11 is 3mm-5mm.When in use, people pull out pin cap according to flank 13, make the hands of pressing flank 13 farther from syringe needle like this, effectively prevent hands by the danger of punctures, and the position that flank 13 contacts with hands is arc-shaped, more comfortable when making people press flank 13 like this, and it is more firm, because the bottom of pin cap body 11 is provided with sucker 15, pin cap can be inverted on the table when pulling out pin cap, sucker 15 just can be inhaled on the table, after such syringe is finished using, syringe needle can be directly made to insert pin cap, one hand just can complete operation, more convenient, sucker 15 also can be inhaled on wall or place more smoothly at one's side by people as required, and be connected by support bar 14 between sucker 15 with pin cap body 11, when syringe needle is injected pin cap by such people, pin cap generation inclination to a certain degree can be made as required, namely the sensing of pin cap opening 12 is changed, use convenient.
Its operation principle is:
As Fig. 1, the screw first will unclamped in screw 51 before intravenous injection, turns stop nut 5 to precalculated position with hands, then tightens screw with fixing stop nut 5, and rotate caudal peduncle 6, medicinal liquid enters in patient body.When arteries and veins is expelled to predetermined amount, stop nut can be blocked by syringe, thus can not the amount of pushing through.Complete injection.
Push rod 4 is provided with scale, is that conveniently stop nut 5 finds precalculated position accurately.
Claims (2)
1. an intravenous injector, comprise syringe (3) and push rod (4), the front end fixed needle (2) of syringe (3), syringe needle (2) outside is provided with pin cap (1), it is characterized in that: the inwall of described syringe (3) is provided with screw thread, the outer surface of push rod (4) is provided with the external screw thread (41) mated with the screw thread of syringe (3), syringe (3) is threaded with push rod (4), the rear end of push rod (4) is caudal peduncle (6), push rod (4) is provided with stop nut (5), the side of stop nut (5) is provided with screw (51), and screw has screw in (51).
