Description

A kind of intravenous indwelling needle with anti-drop tube

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a venous indwelling needle which is able to prevent the tube from falling off.

Background Art

Intravenous catheters are commonly used medical devices in nursing work. They are easy to use and can reduce the number of punctures on patients, thereby reducing repeated punctures during clinical infusions, reducing the patient's puncture pain and the workload of clinical nursing staff. Therefore, they have been widely used in today's clinical practice and are also frequently used in obstetrics and gynecology.

Since the existing indwelling intravenous needle is generally inserted into the back of the parturient's hand, when the parturient's physiological uterine contraction pain causes the parturient to be restless and unable to control herself, the infusion hose is easily pulled, causing the indwelling needle to fall out of the tube. In addition, when the parturient sweats profusely, the transparent dressing shifts, the adhesion decreases, and the edge rolls up, causing the indwelling needle to fall out of the tube. In the second stage of labor, the parturient exerts force with both hands, and the skin on the back of the hand is tightened, which causes the transparent dressing to shift from the skin and reduce the adhesion, which easily causes the indwelling needle to fall out of the tube.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-4. The utility model provides a technical solution: an anti-drop tube intravenous indwelling needle, including a main tape 1 and an infusion tube 2, one side of the main tape 1 is fixedly connected with a fixing tape 1 6 and a fixing tape 2 13, the length of the main tape 1 is 11 cm, and the width is 7 cm, and the main tape 1, the fixing tape 1 6 and the fixing tape 2 13 are all made of anti-allergic tape, and the main tape 1 fixes the infusion tube 2 through the fixing tape 1 6 and the fixing tape 2 13 On one side of the main tape 1, an observation window 8 is opened inside the main tape 1. The length of the observation window 8 is six centimeters and the width is four centimeters. The needle 12 is located on the inner side of the observation window 8.
