Abstract
The utility model relates to a prevent that disconnected liquid returns transfer line of blood, including the body, still include the elasticity line be equipped with the stopper that can plug up the body when not receiving intraductal liquid medicine buoyancy in the body in the body the below of stopper is equipped with the mount, the upper end of elasticity line is connected the bottom of stopper, its lower extreme is connected the mount, and the biggest elasticity of elasticity line is less than the stopper is in the buoyancy of the intraductal liquid medicine that receives in the body, the stopper is plugged up in the time of the body, the elasticity line is tensile state. The utility model provides a prevent that disconnected liquid returns transfer line of blood can effectually prevent the process interrupt liquid in the infusion, guarantees the safety of patient at the infusion in -process.
Description
Technical field
This utility model relates to medical apparatus, is specifically related to a kind of tube for transfusion of anti-breaking liquid blood back.
Background technology
Infused by tube for transfusion in clinical, in the process of transfusion, tube for transfusion can not break liquid, once disconnected liquid in tube for transfusion, can bring danger, even can cause death to patient.The Chinese patent that patent is called " liquid continuous providing type blood return transfusion dropper tube ", the patent No. is 200720139249.6 discloses in a kind of body the stilligout preventing disconnected liquid blood back being provided with air pressure and cutting off bead, relies on hollow beads to block body, but and unreliable.Because in order to medicinal liquid can be made to float bead, bead adopts hollow setting, this causes the gravity of bead to become very light.Time bead gets lodged in mouth of pipe place, between the outer wall of bead and the inwall of body, space can be produced, or bead does not touch tube wall by not resetting when buoyancy, all can cause the disconnected liquid blood back of tube for transfusion.
Utility model content
In sum, for solving existing technical problem, this practicality provides a kind of tube for transfusion of anti-breaking liquid blood back.
The technical scheme that this utility model solves the problems of the technologies described above is as follows: a kind of tube for transfusion of anti-breaking liquid blood back, comprise body, also comprise elastica, can block the stopper of body when being provided with not managed inner liquid medicine buoyancy in described body, in described body, the below of described stopper is provided with fixed mount;
The upper end of described elastica connects the bottom of described stopper, its lower end connects described fixed mount, and the maximum elastic force of described elastica be less than described stopper in described body the buoyancy of managed inner liquid medicine, described in described plug when body, described elastica is extended state.
Further, described fixed mount is three poles be in same level, and one end of three described poles is fixed on the inwall of described body, and other one end of three described poles extends the central point being pooled to described body.
Further, described elastica is connected to the Rendezvous Point of three described poles.
Further, described stopper is inner engraved structure, it inverted tapered segment matched with pencil comprising the column part on top and bottom.
The beneficial effects of the utility model are: this practicality provides a kind of tube for transfusion of anti-breaking liquid blood back, effectively can prevent the process interrupt liquid in transfusion, ensure the safety of patient in infusion process.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
In accompanying drawing, the list of parts representated by each label is as follows:
1, body, 2, elastica, 3, stopper, 4, fixed mount, 5, pole.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining this utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of tube for transfusion of anti-breaking liquid blood back, comprise body 1, also comprise elastica 2, the stopper 3 of body 1 can be blocked when being provided with not managed inner liquid medicine buoyancy in described body 1, in described body 1, the below of described stopper 3 is provided with fixed mount 4, the upper end of described elastica 2 connects the bottom of described stopper 3, its lower end connects described fixed mount 4, and the maximum elastic force of described elastica 2 be less than described stopper 3 in described body 1 the buoyancy of managed inner liquid medicine, time described stopper 3 blocks described body, described elastica 2 is nature retracted position.Wherein stopper 3 is inner engraved structure, and it comprises the inverted tapered segment that the column part on top and bottom and pencil match.
As shown in Figure 2, described fixed mount 4 is fixed on the inwall of described body 1 for the one end being in three poles, 5, the three described poles 5 in same level, and other one end of three described poles 5 extends the central point being pooled to described body 1.Described elastica 2 is connected to the Rendezvous Point of three described poles 5.
In time not having medicinal liquid in body 1, stopper 3 can by stopper 3 toward drop-down under the effect of elastica 2 elastic force, and the inwall making stopper 3 be close to body 1 blocks body 1, can not cause the disconnected liquid of tube for transfusion.Elastic 2 pairs of stoppers produce downward pulling force, compensate for stopper 3 because inner hollow out and the too small defect cannot blocking body 1 of gravity.In addition under the pulling force effect of elastic 2, stopper 3, not by meeting parking position accuracy when buoyancy, in the process namely by buoyancy decline, can not be stuck in body 1, cause disconnected liquid in pencil in run-off the straight.When having medicinal liquid in body 1, stopper 3 rises by after buoyancy, and medicinal liquid is just by pencil input patient body.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
