Abstract

The utility model discloses a safety anti-falling transfusion device, which comprises a transfusion tube and a puncture needle arranged at one end of the transfusion tube. Connected to the inner wall below the puncture needle, the top of the shrapnel has a spherical end protruding through the round hole, and the middle and lower part of the puncture needle is also equipped with a squeeze button that can push the shrapnel to make the spherical end out of the round hole. Use this to prevent falling off When connecting the infusion set to the infusion bottle, press the squeeze button first to separate the spherical end of the shrapnel from the round hole on the side wall above the puncture needle, so that the puncture needle can be smoothly inserted into the cork of the infusion bottle. Press and squeeze the button, the shrapnel returns to the initial position under the action of elastic force, and then drives the spherical end of the shrapnel to protrude through the round hole, and the protruding spherical end is stuck on the top of the bottle stopper, so that the infusion set and the infusion bottle The connection is firmer and not easy to fall off, reducing the waste or pollution of liquid medicine.

Description

A kind of safety anti-falling infusion set

technical field

    The utility model relates to the technical field of medical appliances, in particular to an infusion set.

Background technique

    When the existing infusion set is used to infuse the patient, the puncture needle inserted into the stopper of the infusion bottle will easily come out and fall off with a slight pull, especially for children or comatose patients, the infusion set falls off more frequently , The infusion set falls off and causes liquid medicine waste, pollution, and also prone to needle stick accidents, thereby increasing the workload of medical staff.

Utility model content

The technical problem to be solved by the utility model is to provide a safety anti-falling infusion set which is easy to use and safer for infusion.

The technical solution adopted to solve the above technical problems: a safety anti-falling infusion set, including an infusion tube and a puncture needle at one end of the infusion tube, a round hole is opened on the side wall above the puncture needle, and the puncture needle There is a shrapnel inside, the bottom end of the shrapnel is fixedly connected to the inner wall below the puncture needle, the top of the shrapnel has a spherical end protruding through the round hole, and the middle and lower part of the puncture needle is also provided with a shrapnel that can be pushed to make it Squeeze button with ball end disengaged from round hole.

Further, the push button is a soft cavity protruding from the middle and lower part of the puncture needle, and a protruding block protruding into the soft cavity is provided at the middle and lower part of the elastic sheet.

Beneficial effects: when using the safety anti-falling infusion set to connect with the infusion bottle, press the extrusion button first to make the spherical end of the shrapnel break away from the round hole on the side wall above the puncture needle, so that the puncture needle can be smoothly inserted into the bottle of the infusion bottle After the plug is inserted smoothly, release the squeeze button, and the shrapnel returns to the initial position under the action of the elastic force, and then drives the spherical end of the shrapnel to protrude through the round hole, and the protruding spherical end is stuck on the cork. The upper part makes the connection between the infusion set and the infusion bottle more firm, and it is not suitable for falling off, reducing the waste or pollution of liquid medicine, reducing needle stick injuries, and reducing the workload of medical staff.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further;

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is a partial structural schematic diagram of an embodiment of the utility model.

Detailed ways

Referring to Fig. 1 and Fig. 2, the utility model is a safety anti-falling infusion set, comprising an infusion tube 1 and a puncture needle 2 arranged at one end of the infusion tube 1, a circular hole 21 is opened on the side wall above the puncture needle 2, and the puncture needle 2 is provided with a shrapnel 3, the bottom of the shrapnel 3 is fixedly connected to the inner wall below the puncture needle 2, the top of the shrapnel 3 has a spherical end 31 protruding through the round hole 21, and the middle and lower part of the puncture needle 2 is also provided with a pushable The elastic sheet 3 makes the spherical end 31 detach from the push button 22 of the round hole 21 .

When using this safety anti-falling infusion set to connect with the infusion bottle, first press the squeeze button 22 to make the spherical end 31 of the shrapnel 3 break away from the round hole 21 on the upper side wall of the puncture needle 2, so that the puncture needle 2 can be smoothly inserted into the infusion After the cork of the bottle is successfully inserted, the squeeze button 22 is released, and the shrapnel 3 returns to the initial position under the action of the elastic force, and then drives the spherical end 31 of the shrapnel 3 to protrude through the round hole 21, and protrudes outward. The spherical end 31 is stuck on the top of the bottle stopper, so that the infusion set and the infusion bottle are connected more firmly, and it is not suitable for falling off, so as to reduce the waste or pollution of liquid medicine.

In this embodiment, the upper part of the entire puncture needle 2 is a steel needle, and the lower part is a rubber needle tube connected with the infusion tube 1. The round hole 21 is opened on the steel needle, and the extrusion button 22 is arranged on the rubber needle. On the needle tube, a soft cavity is protruded on the needle tube as the extrusion button 22, and the middle and lower part of the shrapnel 3 is provided with a raised block 32 matching the size of the soft cavity. The cavity can squeeze the protruding block 32, and then drive the spherical end 31 at the top of the shrapnel 3 to move.

The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the above-mentioned embodiments. Various changes are made.
