Abstract
This utility model provides a kind of pre-filled flushing syringe, comprise sleeve, described barrel forward end be provided with one with sleeve one hollow puncture needle, the syringe needle of puncture needle is in sleeve inner, point to piston A, backshank exposes sleeve, piston A in sleeve and piston B is by flushing liquor and tube-sealing solution insulation package, flushing liquor is encapsulated in sleeve front portion, tube-sealing solution is encapsulated between piston B and piston A, and piston B and pull bar link together, and junction can rotate, piston B is provided with steam vent, pull bar is provided with the steam vent corresponding with it.Washing pipe liquid of the present utility model and tube-sealing solution coexist and same flushing syringe, can simplify the operating process of user, increase work efficiency, and reduce production cost and patient's cost of use.
Description
Technical field
This utility model belongs to medical instruments field, specifically be a kind of pre-filled flushing syringe.
Background technology
The use of inlying catheter establishes long-term vascular access for needing the patient of long-term intravenous infusion treatment or other haemodialysis, avoids venipuncture repeatedly, alleviates the misery of patient.The nursing of inlying catheter first being rinsed to rear tube sealing is all needed after each treatment, inlying catheter washing pipe and tube sealing carry out respectively with two flushing syringes clinically at present, this disposal options had both added nurse job amount and labor intensity, turn increase the risk of patient infection, also add the medical expense of patient simultaneously.
Utility model content
The technical problems to be solved in the utility model is that indwelling tube rinses, tube sealing needs a point different syringe to carry out, its troublesome poeration, the problem that patient infection has a big risk, treatment cost is high.
The scheme that this utility model solves the problems of the technologies described above is, a kind of pre-filled flushing syringe, comprise sleeve, described barrel forward end be provided with one with sleeve one hollow puncture needle, the syringe needle of puncture needle is in sleeve inner, point to piston A, backshank exposes sleeve, piston A in sleeve and piston B is by flushing liquor and tube-sealing solution insulation package, and flushing liquor is encapsulated in sleeve front portion, and tube-sealing solution is encapsulated between piston B and piston A, piston B and pull bar link together, junction can rotate, and piston B is provided with steam vent, pull bar is provided with the steam vent corresponding with it.
The position that described piston A is relative with puncture needle head is provided with cavity.Cavity is convenient to puncture needle and is penetrated piston A.
Described puncture needle upper end is angle, and the consistency of thickness of length removing upper end angle part and piston A, is being provided with liquid outlet with sleeve connection place.The liquid outlet at sleeve connection place can ensure that flushing liquor is all discharged, and upper end inclined opening structure is convenient to tube-sealing solution and is all discharged.
Described puncture needle is plastic puncture needle, exposes the backshank of sleeve and block fitted seal.
Its reasonable in design of the pre-filled flushing syringe of this utility model, can tube-sealing solution and washing pipe liquid be stored in a flushing syringe simultaneously, greatly reducing nurse job amount and labor intensity, decrease the risk of patient infection, reduce production cost simultaneously, decrease the medical expense of patient.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model;
Fig. 2 piston B of the present utility model and Tiebar structure schematic diagram.
In figure, 1 pull bar, 2 piston B, 3 tube-sealing solutions, 4 piston A, 5 sleeves, 6 puncture needles, 7 liquid outlets, 8 blocks, 9 flushing liquors, 10 cavitys, 11,12 steam vents.
Detailed description of the invention
Pre-filled flushing syringe of the present utility model, comprise sleeve 5, described sleeve 5 front end be provided with one with sleeve one hollow puncture needle 6, the syringe needle of puncture needle 6 is in sleeve inner, point to piston A4, backshank exposes sleeve 5, piston A4 in sleeve and piston B2 is by flushing liquor 9 and tube-sealing solution 3 insulation package, it is anterior that flushing liquor 9 is encapsulated in sleeve 5, tube-sealing solution 3 is encapsulated between piston B2 and piston A4, and piston B2 and pull bar 1 link together, and junction can rotate, piston B2 is provided with steam vent 11, pull bar 1 is provided with the steam vent 12 corresponding with it.The position that piston A4 is relative with puncture needle 6 syringe needle is provided with cavity 10.Puncture needle 6 upper end is angle, and the consistency of thickness of length removing upper end angle part and piston A4, is being provided with liquid outlet 7 with sleeve connection place.
Appropriate flushing liquor 9 is loaded by square socket under piston A4 5, piston A4 loads onto tube-sealing solution 3 in square socket 5, pull bar 1 is fitted together with piston B2, the steam vent 11 on piston B2 and the steam vent 12 on pull bar is utilized to coordinate aerofluxus, behind position suitable for piston B2 propelling sleeve 5, rotating rod 1, steam vent 11 and steam vent 12 are staggered, assembling completes.
During washing pipe, opened by block 8, pushing drawing rod 1, while flushing liquor 9 is released sleeve 5 from puncture hole and liquid outlet 12, piston A4 is pierced through and tube-sealing solution 3 is connected in puncture needle 6 upper end, then pushing drawing rod 1, releases tube-sealing solution 3 from puncture hole upper end 1 and carries out tube sealing.
