Description

UFO Safety Infusion Set Dropping Funnel

technical field

The utility model relates to a sterile medical device used for clinical transfusion, in particular to a flying saucer type safety transfusion device dripping funnel.

Background technique

In the clinical infusion process, usually a medical staff has to take care of the infusion of patients in several wards. If the infusion bottle is replaced in time or the infusion needle is pulled out, the liquid level drops too low, causing gas to enter the human body and cause gas embolism and other adverse consequences, which brings a heavy mental burden to medical staff, patients or patients' families.

Contents of the invention

The purpose of this utility model is: to provide a disposable flying saucer-type safety infusion dripping funnel, which can automatically block the liquid outlet of the dripping funnel when the infusion is nearly completed, so that the liquid in the infusion line stops flowing, preventing air from entering the patient's body and Blood backflow in the body, one-time use, ensuring safety.

The utility model is realized through the following technical proposals: the dropping hopper of the flying saucer type safety infusion device includes a protective cover, a cork puncturer, an upper section of the dropping hopper, a lower section of the dropping hopper and a silica gel flying saucer, the protective cover is set on the bottle stopper puncturer, the bottle The plug puncturer is set on the upper part of the drip funnel, and the lower part of the drip funnel is equipped with a silicone flying saucer, which constitutes a flying saucer-type safety infusion set drip funnel as a whole; its feature is: the center of the silicone flying saucer is two symmetrical notches up and down, and there is a layer of sealing between the two notches Membrane, the sealing membrane is facing the infusion port in the lower part of the dropping funnel, and there are four symmetrical liquid hole grooves on the surface of the dish.

Wherein, the inner interface of the upper section of the dripping funnel is provided with a stop riser at the end of the outer interface of the lower section of the drip funnel, and the silicone flying saucer moves between the stop riser and the infusion port.

The further technical scheme of the utility model is: the liquid medicine filter seat integrally formed by injection molding with the infusion port is set in an inverted funnel shape, the bottom of the lower part of the drip funnel is set in a funnel-shaped notch, and the liquid medicine filter is fixed on the medicine liquid filter by high-frequency heat sealing. The liquid filter seat is installed on the inner bottom surface of the lower part of the notch dropping funnel together.

Wherein, the dropper of the cork piercer is directly connected to the blow-molding dropping funnel, and the blow-molding dropping funnel and the injection-molding dropping funnel are interchangeable and universal.

Among them, the capacity of the dripping funnel after the combination of the upper part of the dropping funnel and the lower part of the dropping funnel is: 6cc, 8cc, 10cc, 12cc, 14cc.

Another technical solution of the utility model is: on the basis of ordinary disposable infusion sets, various types of bottle stopper piercers are commonly used, including bottle stopper piercers with exhaust, bottle stopper piercers with exhaust and wings, Winged cork piercer without vent, cork piercer without vent.

When starting the infusion, the liquid first drops into the notch in the center of the silicone flying saucer, and then diverts to the liquid hole and flows into the bottom of the drip funnel. As the liquid level rises, the silicone flying saucer rises under the buoyancy of the liquid, and the sealing film breaks away from the infusion port. Realize the infusion process, when the infusion is nearly completed, the silicone flying saucer will drop with the liquid level, and when the sealing film contacts the infusion port, under the atmospheric pressure and the pressure of the silicone flying saucer’s own weight, the sealing film will tightly block the infusion port to prevent air from entering To the infusion pipeline below the infusion port, so as to prevent air from entering the human body and blood backflow in the body, and realize safe infusion.

The utility model is simple in structure, safe and reliable. When the infusion is about to be completed, the liquid outlet of the drip funnel of the infusion set is automatically blocked, so that the liquid medicine in the infusion pipeline at the lower end of the liquid outlet stops flowing and automatically ends the infusion, preventing air from entering the patient's body and body. Blood backflow ensures safe transfusion, which has very positive significance for further reducing and avoiding the occurrence of medical accidents.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figures 1, 3, and 4, the flying saucer-type safety infusion set dripper includes a protective cover 1, a cork piercer 2, an upper section 4 of the dripping funnel, a lower section 5 of the dripping funnel, and a silicone flying saucer 6. The protective cover 1 is set on the bottle stopper. On the piercer 2, the cork piercer 2 is set on the upper section 4 of the drip funnel, and the lower section 5 of the drip funnel is equipped with a silicone flying saucer 6, which constitutes a flying saucer-type safety infusion drip funnel as a whole; its feature is: the center of the silicone flying saucer 6 is symmetrical up and down Notches, a layer of sealing film 6a is arranged between the two notches, and the sealing film 6a is facing the infusion port 5a of the lower section 5 of the dropping funnel, and four symmetrical liquid hole grooves 6b are opened on the surface of the dish.

As shown in FIG. 1 , the inner interface of the upper section 4 of the dropping funnel is provided with a lift-stop 4a at the end of the outer interface of the lower section 5 of the drip funnel, and the silicone flying saucer 6 moves between the lift-stop 4a and the infusion port 5a.

As shown in Figure 2, the further technical scheme of the utility model is: the liquid medicine filter seat 8 integrally injection-molded with the infusion port 5a is set to an inverted funnel shape, the bottom of the notch dropping funnel lower section 5B is set to a funnel shape, and the liquid medicine The filter screen 9 is fixed on the liquid medicine filter seat 8 by high-frequency heat sealing to form a liquid medicine filter 10 installed on the inner bottom surface of the notch dropping funnel lower section 5B.

As shown in Figure 5-11, the dropper of the cork piercer 2 is directly connected to the blow molding dropper 4B, and the blow molding dropper 4B is interchangeable with the injection molding dropper 4A.

As shown in Figure 5-11, on the basis of ordinary disposable infusion sets, various types of cork piercers 2 are commonly used, including cork piercer 2A with venting, cork piercer 2B with venting and wings , Bottle cork piercer 2C with wings without exhaust, bottle cork piercer 2D without exhaust.

When starting the infusion, the liquid first drops in the center notch of the silicone flying saucer 6 and then diverts to the liquid through hole and flows into the bottom of the lower section 5 of the dropping funnel. As the liquid level rises, the silicone flying saucer 6 rises under the buoyancy of the liquid, and the sealing membrane 6a is separated from the infusion port 5a to realize the infusion process. When the infusion is nearly completed, the silicone flying saucer 6 will drop with the liquid level until the sealing film 6a contacts the infusion port 5a. Tightly seal the infusion port 5a so that air does not enter the infusion pipeline below the infusion port 5a, thereby preventing air from entering the human body and backflow of blood in the body, and realizing safe infusion, which is very positive for further reducing and avoiding the occurrence of medical accidents meaning.
