Abstract
The invention discloses a disposable heparin sodium normal saline tube-sealing fluid suit. The disposable heparin sodium normal saline tube-sealing fluid suit comprises an injector, wherein the injector comprises a cylinder body, a piston and a push rod; an outlet is formed in the cylinder body; a cover is arranged on the outlet; two cavities are partitioned between the outlet and the piston in the cylinder body, one cavity is filled with heparin sodium, and the other cavity is filled with normal saline. The two solutions for tube sealing are independently sealed in the injector; when the suit is used, firstly the two cavities are communicated, then the solutions are uniformly mixed, namely the suit can be used, so that the operation is extremely convenient, the workload of medical staffs is reduced, and the waste is avoided.
Description
Technical field
The present invention relates to a kind of disposable heparin sodium normal saline tube-sealing solution suit.
Background technology
Transfusion central venous catheter, after infusion-completed, blood easily backflows in conduit, frozen plug conduit.Therefore need, with the liquid tube sealing containing anticoagulant, to prevent blood reflux obstruction conduit after infusion-completed.Clinical conventional normal saline and heparin sodium adapted in proportion, matching while using.
Conventional tube-sealing solution is made up of 0.9% normal saline and heparin sodium two parts, and 0.9% normal saline 100ml mixes the heparin sodium normal saline being made into 125u/ml with heparin sodium 12500u, must use, otherwise lost efficacy after the two mixing within 24 hours.Therefore, clinical is all matching while using, then extracts wherein 15ml, carries out tube sealing use, and remaining 85ml heparin sodium normal saline is wasted, and clinical manipulation is loaded down with trivial details.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of disposable heparin sodium normal saline tube-sealing solution suit.
In order to solve the problems of the technologies described above, the present invention includes syringe, syringe comprises cylindrical shell, piston and push rod, cylindrical shell is provided with outlet, outlet is provided with lid, between outlet and piston, be separated into two chambers in described cylindrical shell, one of them chamber has heparin sodium, and another chamber fills normal saline.
Get through for the ease of two chambers, make two kinds of solution mixing, two described chambers are separated by barrier film, and the edge of barrier film is connected with the inner wall sealing of cylindrical shell.
For ease of tearing barrier film, described barrier film there is the tear line extending to diaphragm edge from diaphragm center.
In order to make the barrier film after tearing separate from center to edge, form larger connected entrance, described tear line has 4, is arranged in cross.
Make two chamber for the ease of opening barrier film, described lid is provided with film breaking unit.
In order to rupture of membranes is easy to operate, described film breaking unit comprises nail bar and spring, nail rod seal is plugged on and covers, the one end at the nail tip place of nail bar is in the other end in cylindrical shell and is in outside lid, spring connected nail bar and lid, when to follow closely on bar not external force action time, nail bar does not contact with barrier film, when following closely bar outer end pressurized, nail bar has the state puncturing barrier film.
In order to not only be convenient to rupture of membranes but also be convenient to mixing two kinds of solution, described film breaking unit comprises guide rod and spring, and guide rod sealing is plugged on and covers, and guide rod is in the outer other end of lid and is fixedly connected with barrier film, spring connects guide rod and lid, and the contact internal walls place of barrier film and cylindrical shell is for tearing position.Barrier film can tear it down from cylindrical shell by guide rod, and the barrier film torn it down can serve as stirring vane, makes the married operation of solution convenient.
The invention has the beneficial effects as follows: two of tube sealing kinds of solution individual packages in a syringe, only need during use first to be got through by two chambers by the present invention, then by solution mix homogeneously, can use, easy to operate, decrease the workload of medical personnel, and avoid waste.

Detailed description of the invention
Specific embodiment one
A kind of specific embodiment as depicted in figs. 1 and 2, it comprises syringe, syringe comprises cylindrical shell 4, piston 5 and push rod 6, cylindrical shell 4 is provided with outlet 2, outlet 2 is provided with lid 1, and the syringe of this kind of form is prior art, and this patent increases following structure on the basis of present syringe: between outlet 2 and piston 5, be separated into chamber 7 and chamber 8 in cylindrical shell 4, chamber 7 fills heparin sodium, and chamber 8 fills normal saline.Chamber 7 and chamber 8 are separated by barrier film 3, and the edge of barrier film 3 is connected with the inner wall sealing of cylindrical shell 4.Barrier film 3 there is the tear line 3-1 extending to barrier film 3 edge from the center of barrier film 3.Tear line 3-1 has many, is arranged in cross.
Operational approach: pull back push rod 6, barrier film 3 is subject to suction when reaching a certain size, and tear line 3-1 tears, make membrane ruptures, or open lid 1, use pin to be punctured by barrier film, rock syringe and make two kinds of solution mix homogeneously, open lid 1, solution is pushed transfusion central venous catheter.
Specific embodiment two
As shown in Figure 3, this specific embodiment is with the difference of specific embodiment one: barrier film 3 is not provided with tear line, lid 1 is provided with film breaking unit.Film breaking unit comprises nail bar 9 and spring 10, the sealing of nail bar 9 is plugged on lid 1, the one end at the nail tip place of nail bar 9 is in the other end in cylindrical shell 4 and is in outside lid 1, spring 10 connected nail bar 9 and lid 1, when to follow closely on bar 9 not external force action time, nail bar 9 does not contact with barrier film 3, and when following closely bar 9 outer end pressurized, nail bar 9 has the state puncturing barrier film 3.
