When the liquid medicine drops and there is no medicine liquid dripping from the top, the sealing float can descend with the medicine liquid, and block the upper opening of the lower tube in time. It prevents air from entering the human body during pressurized infusion, and completely avoids the possibility of air embolism. It can prevent the liquid from flowing to the bottom of the Murphy dropper, and there is no need to deal with the adverse phenomenon of liquid medicine being discharged due to improper infusion, which ensures the physical and mental health of patients, medical staff, and accompanying staff. It avoids the phenomenon of blood returning and needle plugging caused by excessive liquid drop, and the structure is simple.

Description

New Mufei dropper infusion set

technical field

The utility model relates to a medical appliance commonly used in a hospital, in particular to a new-style muphy dropper infusion set.

Background technique

Infusion equipment is an essential device for infusion to patients, usually using a muphy dropper infusion set for infusion. The existing muphy dropper infusion set includes a section of muphy dropper whose diameter becomes thicker, and the lower part is connected with a lower tube of the infusion solution. During infusion, the liquid level of the liquid medicine is displayed in the cavity of the thick diameter part to indicate the state of infusion. The infusion set with this structure has the following disadvantages: one is that air can easily enter the human body during pressurized infusion, which may cause air embolism; When taking medicine, it is often found that the liquid has flowed under the Murphy dropper. If necessary, the nurse needs to drain the liquid to the outside. This not only wastes the medicine, but also cannot guarantee the amount of medicine injected into the patient's body, resulting in unnecessary medical disputes. It will also pollute the environment and expose radioactive drugs to the air, which will have an impact on the health of patients, medical staff, and accompanying staff;

Contents of the invention

The purpose of this utility model is to provide a new type of Maofei dropper infusion device with simple structure, preventing gas from entering the human body, smooth replacement of medicinal liquid, no need to expel medicinal liquid to deal with inappropriate infusion, and preventing blood back phenomenon, so as to overcome the disadvantages of the prior art. insufficient.

The new muphy dropper infusion set of the utility model comprises a muphy dropper, a lower tube is connected below the muphy dropper, and a sealing float matching the upper port of the lower tube is arranged inside the muphy dropper.

In the new muphy dropper infusion set of the present utility model, the upper end of the lower tube extends into the inner cavity of the muphy dropper, and the sealing float is plate-shaped or spherical.

In the new Maufei dropper infusion set of the present utility model, there is an outwardly rolled flange around the upper port of the lower tube, and the flange is matched with the sealing float.

In the new Mofei dropper infusion set of the present utility model, the center position of the bottom of the sealing float is connected with one end of the pull wire, the other end of the pull wire is connected with the bracket, and a convex edge is provided on the inner side of the lower tube. The bracket is located under the chime.

In the novel muphy dropper infusion set of the utility model, the sealed float can float in the medicinal liquid in the inner cavity of the thick diameter part of the muphy dropper during infusion, and is controlled by a pull wire, and is limited by a bracket and a convex edge to float up. When the liquid medicine drops and there is no medicine liquid dripping from the top, the sealing float can descend with the medicine liquid, and block the upper opening of the lower tube in time. It prevents the occurrence of air entering the human body during pressurized infusion, and completely avoids the possibility of air embolism. It is especially suitable for rescuing and treating a large number of wounded and insufficient medical staff. It can prevent the liquid from flowing under the Murphy dropper, especially for the infusion of some chemotherapy and irritating and volatile drugs. When changing the liquid, there is no need to deal with the adverse phenomenon of efflux of the liquid due to improper infusion, which ensures the patient and medical staff , The physical and mental health of the accompanying personnel. It avoids excessive drop of liquid to cause blood return and needle plugging, and has the characteristics of simple structure.

Detailed ways

As shown in Figure 1: 1 is a muphy dropper, a lower pipe 4 is connected below the muphy dropper 1, and a sealing float 7 matching the upper port of the lower pipe 4 is provided in the muphy dropper 1. The upper end of the lower tube 4 extends into the inner cavity of the Murphy dropper 1, and the sealing float 7 is in the shape of a plate or sheet, as long as the sealing float 7 falls on the upper port of the lower tube 4, the lower tube 4 can be blocked. For better sealing, there is a flange 3 rolled outwards around the upper port of the lower tube 4, and the flange 3 is matched with the sealing float 7. The center position of the bottom of the sealing float 7 is connected with one end of the backguy 2 , and the other end of the backguy 2 is connected with the support 5 , and the inner side of the lower tube 4 is provided with a flange 6 , and the support 5 is located below the flange 6 .

During infusion, the sealing float 7 can float in the medicinal liquid in the inner cavity of the thick diameter part of the Murphy dropper 1, and is controlled by the pull wire 2, and is limited by the support 5 and the convex edge 6 to float up. When liquid medicine descends, when the top does not have medicine liquid to drip, sealing float 7 can descend with medicine liquid, and the upper opening of down pipe 4 is blocked in time. It prevents the occurrence of air entering the human body during pressurized infusion, and completely avoids the possibility of air embolism. It can prevent the liquid from flowing to the bottom of the Murphy dropper, and there is no need to deal with the adverse phenomenon of liquid medicine being discharged due to improper infusion, which ensures the physical and mental health of patients, medical staff, and accompanying staff. Avoid excessive drop of liquid, resulting in blood return and needle blockage.

As shown in Figure 2: the difference from the above is that the sealing float 7 is spherical and matches with the upper port of the lower tube 4. When the spherical sealing float 7 falls to the upper port of the lower tube 4 with the liquid level, the lower tube 4 can be blocked.
