Description

an infusion device

technical field

The utility model relates to the field of medical instruments, in particular to an infusion device.

Background technique

Intravenous infusion is a method of injecting a large amount of sterile liquid, electrolytes, and drugs into the body through the vein using the principles of atmospheric pressure and hydrostatic pressure. The most important of these is sterility. The infusion devices used in the current ward will have the following problems when they are used. As the patient moves, the bottle stopper piercer will rotate and loosen in the liquid bottle. If it is pulled, the infusion device may be pulled from the liquid. Ripped off from the bottle.

Utility model content

The utility model aims at providing an infusion device, which fixes a bottle stopper puncturer and a liquid bottle together to prevent the infusion device from coming out of the liquid bottle.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

An infusion device, comprising a liquid bottle, an infusion hose, a cork piercer and a fixed claw, the liquid bottle has a cork and a cap, and the cap has a flange; one end of the cork piercer passes through The bottle cap and the bottle stopper communicate with the inside of the liquid bottle, the other end of the bottle stopper piercer is connected with one end of the infusion hose, one end of the fixed claw is connected with the bottle stopper piercer, and the other end of the fixed claw is caught on the flange of the bottle cap Above, there are at least two fixed claws.

Preferably, the fixed claw includes a horizontal part and an elastic arm, the inner surface of the horizontal part is attached to the outer surface of the bottle cap, one end of the horizontal part is connected to the outer wall of the cork piercer, and the other end of the horizontal part is connected to the elastic arm. The elastic arms are connected to each other, and the elastic arms are inclined inwardly, and the ends of the elastic arms catch on the flange of the bottle cap.

Further, there is a venous needle at the other end of the infusion hose, and an air vent, a drip pot, a flow rate regulator and a liquid medicine filter are sequentially arranged between the cork puncturer and the venous needle.

Further, the flange is arranged on the top of the bottle cap.

Preferably, the cork piercer and the fixed claw are manufactured in one piece.

Further, the horizontal part and the elastic arm are integrally manufactured.

Further, the cork piercer and the fixing claw are made of medical plastic.

Compared with the prior art, the utility model has the following beneficial effects:

1. The fixed claw fixes the cork piercer and the liquid bottle together to prevent the cork piercer from coming out of the liquid bottle;

2. The inner surface of the horizontal part of the fixed claw fits closely with the outer surface of the bottle cap, so that the cork piercer is always submerged in the liquid bottle, avoiding contamination of the cork piercer and preventing bacteria from entering the patient's blood.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, the transfusion device disclosed by the utility model comprises a liquid bottle 1, an infusion hose 3, a bottle stopper puncturer 5 and a fixed claw 4, and the liquid bottle 1 has a bottle stopper and a bottle cap 2, and the bottle cap 2 There is a flange on the top, one end of the cork piercer 5 passes through the bottle cap 2 in turn, and the bottle cork communicates with the inside of the liquid bottle 1, the other end of the cork piercer 5 is connected with one end of the infusion hose 3, and one end of the fixed claw 4 is connected with the bottle The stopper piercer 5 is connected, and the other end of the fixed claw 4 is grasped on the flange of the bottle cap 2. There are at least two fixed claws 4. The bottle stopper piercer 5 and the fixed claw 4 are made of medical plastics. Preferably, the The fixed claw 4 includes a horizontal part and an elastic arm, the inner surface of the horizontal part is attached to the outer surface of the bottle cap 2, one end of the horizontal part is connected with the outer wall of the bottle stopper piercer 5, and the other end of the horizontal part is connected with the elastic arm, so The elastic arm is inclined inwardly, the end of the elastic arm is grasped on the flange of the bottle cap 2, and the horizontal part is integrally manufactured with the elastic arm.

As shown in Figure 3, the other end of the infusion hose 3 has a venous needle, and between the bottle stopper puncturer 5 and the venous needle, an air vent, a drip pot 6, a flow rate regulator 7 and a liquid medicine filter are arranged in sequence. The fixed claw of the utility model fixes the cork puncturer and the liquid bottle together, preventing the bottle cork puncturer from coming out of the liquid bottle.

Certainly, the utility model also can have other multiple implementation modes, under the situation of not departing from the spirit and essence of the utility model, those skilled in the art can make various corresponding changes and distortions according to the utility model, but these Corresponding changes and deformations should all belong to the scope of protection of the appended claims of the utility model.
