Description

Y-shaped connector fixer for venous indwelling needle

Technical Field

The utility model relates to a Y-shaped joint fixer for a venous indwelling needle, belonging to the technical field of medical supplies.

Background

The venous indwelling needle is used as a substitute of a scalp needle, is a main tool for clinical transfusion treatment at present, can avoid damage to a patient blood vessel caused by repeated puncture, reduces pain of the patient and improves nursing work efficiency. However, if the indwelling needle is not fixed well, the catheter is easy to slip off and the medicine is easy to leak, which not only shortens the indwelling time of the indwelling needle, but also may damage local tissues.

At present, the conventional retention needle fixation in clinic is directly carried out by adopting a sterile transparent application; however, the edges of the sterile transparent application are often rolled or peeled off, resulting in tape-out, indwelling needle-out, etc. during the indwelling period. The problems that the Y-shaped connector part of the indwelling needle generates extension tube bending in the moving process of a patient, the fixing part is lower than a puncture part and the like easily caused by an improper fixing method are solved, so that continuous transfusion is influenced, and the problems of tube blockage, phlebitis and the like are more likely to occur.

In recent years, many studies have been made on improvement of the fixing effect of a venous indwelling needle, such as self-adhesive elastic bandages. However, in the application process, the phenomena of loosening, pollution, folding, skin abrasion and the like of the remaining needle still occur due to improper movement of a patient, improper bandage fixing method and the like. In use, a nurse also needs to constantly observe whether the bandage is proper in tightness, and whether the bandage is too loose or too tight is not satisfactory. Compared with the condition that the circumference of the limb of a patient is easy to loosen and the proper model is complicated to match, the device does not solve the problems caused by the condition that the normal transfusion is ensured in the reasonable movement range of the patient.

Therefore, how to solve the problems of falling off and slipping caused by the gravity factor of the Y-shaped joint and the like, thereby reducing the shortened service life of the indwelling needle caused by unreasonable and irregular fixation, a new appliance needs to be invented to improve the nursing working efficiency and quality, improve the satisfaction degree of patients and reduce the pain and treatment cost of repeated puncture of the patients.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: the existing method for fixing the Y-shaped joint of the venous indwelling needle by using sterile transparent application or self-adhesive elastic bandage and the like is easy to fall off or slide due to gravity.

In order to solve the above problem, the technical scheme of the utility model provides a needle Y type joint fixer is kept somewhere to vein, its characterized in that: the base is provided with a clamping groove for fixing a first Y-shaped joint pipe and a pressing plate for fixing a second Y-shaped joint pipe, sliding grooves are formed in the base in the direction perpendicular to the second Y-shaped joint pipe, and the pressing plate slides in the sliding grooves along the sliding grooves.

Preferably, the pressing plate comprises an upper pressing plate, a lower pressing plate and a vertical plate, wherein the upper pressing plate and the lower pressing plate are horizontally arranged, the vertical plate is vertically arranged, the upper pressing plate and the lower pressing plate are connected through the vertical plate, and two sides of the lower pressing plate are arranged in the sliding groove.

Preferably, the lower pressing plate is provided with a threaded hole, and a fastener used for fixing the lower pressing plate on the base is arranged in the threaded hole.

Preferably, the fastener is a screw.

Preferably, the clamping groove is a cylindrical groove.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model is convenient to operate and use, can effectively fix the Y-shaped joint of the remaining needle, is not easy to slip, effectively relieves the pain of repeated puncture of patients and reduces the treatment cost.

The utility model discloses the clamp plate is adjustable, can fix not unidimensional needle Y type of keeping somewhere and connect, and the practicality is strong.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 3, the utility model relates to a Y-shaped joint fixer for venous indwelling needle, which comprises a base 1, a slot 2, a chute 3, a pressing plate 4 and a screw 5. A clamping groove 2 is arranged on the base 1, the clamping groove 2 is a cylindrical groove with an opening at the upper part, and a first Y-shaped joint pipe 7 of the remaining needle can be embedded into the clamping groove 2; still install spout 3 on the base 1, the direction perpendicular to Y type joint pipe two 8 of spout 3, clamp plate 4 installs and slides along spout 3 in spout 3. The pressing plate 4 comprises an upper pressing plate 4-1, a lower pressing plate 4-2 and a vertical plate 4-3, the upper pressing plate 4-1 and the lower pressing plate 4-2 are horizontally arranged, the upper pressing plate 4-1 and the lower pressing plate 4-2 are connected through the vertical plate 4-3, two sides of the lower pressing plate 4-2 are arranged in the sliding groove 3 and move back and forth in the sliding groove 3, and the upper pressing plate 4-1 can press the Y-shaped joint pipe II 8 according to different Y-shaped joints; a threaded hole 6 is formed in the center of the lower pressing plate 4-2, a fixing screw 5 is screwed into the threaded hole 6, a small gap is formed between the lower pressing plate 4-2 and the sliding groove 3, the fixing screw 5 is screwed to the base 1, and the lower pressing plate 4-2 is fixed in the sliding groove 3, so that the position of the pressing plate 4 is fixed, and the Y-shaped joint cannot rotate.

When the indwelling needle is fixed, the first Y-shaped connector tube 7 of the indwelling needle is embedded into the clamping groove 2, then the pressing plate 4 is slid, the upper pressing plate 4-1 is pressed on the second Y-shaped connector tube 8, the screw 5 is screwed down, the indwelling needle is fixed on the fixator, and then the fixator is fixed on the skin of a patient through medical double-sided adhesive tape or medical adhesive tape; when the patient does not need to use the remaining needle any more, the fixator is taken down from the skin of the patient, the screw 5 is unscrewed, the pressing plate 4 is slid, the Y-shaped joint pipe II 8 is taken out from the lower pressing plate 4-2, the remaining needle is separated from the fixator, and the fixator is reused.
