Description
Technical field
The present invention relates to medical device, refer in particular to the automatic balancing buoy type safe transfusion tube that is used for human transfusion.
Background technology
At present, the traditional tube for transfusion that uses in clinical treatment (Jimo Fes pipe) needs medical personnel constantly to observe liquid level in use, prevents that transfusion from finishing in the air admission tube for transfusion of back and backflow of blood, this tube for transfusion increase medical personnel's labor intensity.Chinese patent net and United States Patent (USP) all disclose a considerable amount of improvement infusion sets on the net, as Chinese patent CN91231324.2, CN96246144.X, CN0127888.0, CN02285777.X, CN200320110150.5, CN200420094224.5 etc., U.S. Pat 5234414 etc., all there is the deficiency that is difficult to carry out, thereby do not have relevant launch to sell so far yet, bring inconvenience for vast medical personnel.The present inventor improves through research for many years, invented can seal automatically after a kind of transfusion is finished, tube for transfusion safe in utilization.
Summary of the invention
The object of the present invention is to provide a kind of easy to use, work safety, reliable automatic balancing buoy type safe transfusion tube.
The object of the present invention is achieved like this: a kind of automatic balancing buoy type safe transfusion tube comprises the Morphis tube body, wherein: be provided with horizontal baffle in the described body, be tightly connected between the outer rim of dividing plate and the inwall of body; Be provided with through hole at the dividing plate middle part, in through hole, be provided with connecting rod, between connecting rod outer wall and through-hole wall, be provided with fluid passage; Interlinking lever end on dividing plate top is provided with ball-joint head, is with soft closing cover on the ball-joint head, and soft closing cover can be with respect to ball-joint the angle that deflection is certain; Interlinking lever end at the lower partition is connected with float; Contact sealing between the lower surface of described soft closing cover and the upper surface of dividing plate.
Body described in the above-mentioned automatic balancing buoy type safe transfusion tube is made up of upper tube body and lower tube body, is provided with connection tube in the dividing plate periphery, and upper and lower body is plugged on the connection tube both sides respectively.
Inboard wall of tube body described in the above-mentioned automatic balancing buoy type safe transfusion tube is provided with a circle horizontal groove, and the outer rim of dividing plate is embedded in this groove.
Fluid passage described in the above-mentioned automatic balancing buoy type safe transfusion tube is along axially extended many grooves of connecting rod outer wall surface.
After the present invention adopts said structure, because of the lower surface of soft closing cover can with the upper surface of dividing plate between can form and contact sealing, when in the infusion bottle during no liquid, managing intravital liquid level position reduces gradually, float drives soft closing cover with the liquid level reduction by connecting rod and moves down, when the lower surface of soft closing cover with form sealing after the upper surface of dividing plate contacts, can guarantee that like this tube for transfusion is after transfusion is finished and air insulated, prevent in the air admission human body, simultaneously also can prevent backflow of blood, improve the usage safety performance of tube for transfusion; Because of soft closing cover is socketed on the ball-joint head of small end, even skew or connecting rod off-centre (this exists in producing and using at any time) take place body, electric energy guarantees the sealing effectiveness between soft closing cover and the dividing plate simultaneously.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the present invention is described in further detail, but does not constitute any limitation of the invention.
Fig. 1 is the structural representation of the embodiment of the invention 1;
Fig. 2 is the structural representation of the embodiment of the invention 2.
The specific embodiment
Consult shown in Figure 1, automatic balancing buoy type safe transfusion tube of the present invention, comprise Morphis tube body 1, in body 1, be provided with horizontal baffle 2, body 1 is made up of upper tube body 1A and lower tube body 1B again, be provided with connection tube 2B in dividing plate 2 peripheries, upper and lower body 1A, 1B are plugged on the formation of connection tube 2B both sides respectively and are tightly connected; Be provided with through hole 2A at dividing plate 2 middle parts, be provided with connecting rod 3 in through hole 2A, be provided with fluid passage 4 between connecting rod 3 outer walls and through hole 2A inwall, fluid passage 4 is along axially extended four grooves of connecting rod 3 outer wall surface; Connecting rod 3 ends on dividing plate 2 tops are provided with ball-joint 3A, are with soft closing cover 5 on ball-joint the 3A, are connected with float 6 in connecting rod 3 ends of dividing plate 2 bottoms; Can ball-joint relatively the certain angle of 3A deflection because of soft closing cover 5, the gravity that reaches automatic correction float 6 departs from, and forms between the lower surface that makes soft closing cover 5 and the upper surface of dividing plate 2 and contacts sealing.
Consult shown in Figure 2, automatic balancing buoy type safe transfusion tube of the present invention, substantially the same manner as Example 1, the shape difference that different is because of body 1, changed the connected mode between dividing plate 2 and the body 1, be by being provided with a circle horizontal groove 1C at body 1 inwall in the present embodiment, the outer rim of dividing plate 2 is embedded in this groove 1C, can reach and cause same technique effect.
When the present invention specifically uses, consult shown in Figure 1, liquid level during normal infusion in the lower tube body 1B is higher, float 6 up moves under buoyancy function, the lower surface of soft closing cover 5 is not contacted with the upper surface of dividing plate 2, behind the transfusion liquid process upper tube body 1A, in fluid passage 4 flows to lower tube body 1B, realize normal infusion; When no liquid in the upper tube body 1A flows into, liquid level in the lower tube body 1B constantly descends, float 6 constantly descends with liquid level, drive soft closing cover 5 by connecting rod 3 and move down, when the liquid level in the lower tube body 1B arrived certain position, the lower surface of rubber closing cover contacted with the upper surface of dividing plate 2, form the contact sealing, make tube for transfusion and air insulated, can effectively prevent in the air admission human body, also can prevent that blood of human body from flowing backwards simultaneously.And, be socketed in because of soft closing cover 5 on ball-joint the 3A of connecting rod 3 upper ends, even skew takes place body 1 or off-centre takes place connecting rod 3, also can guarantee sealing effectiveness between soft closing cover 5 and the dividing plate 2, use safer, reliable.
