Description

An anti-pollution protective sheath for indwelling needles

technical field

The utility model relates to the technical field of medical equipment, in particular to an anti-pollution protective cover for indwelling needles.

Background technique

The use of indwelling needles can reduce the pain and fear of injections caused by repeated venipuncture in children, relieve the anxiety of parents, facilitate clinical medication, rescue medication for acute and critical patients, reduce the workload of nurses, and reduce the risk of children's anxiety. Pain, so intravenous indwelling needles are widely used clinically. Facing the special group of children, the indwelling time of intravenous indwelling needles and the comfort of children have become the most concerned issues for nurses and parents, and they are also the symbol and promotion of the successful use of indwelling needles. The premise of venous indwelling needle is also called venous trocar. The core components include a soft catheter/cannula that can be indwelled in the blood vessel, and a stainless steel puncture guide core. When used, the catheter and the needle core are punctured into the blood vessel together. Inside, when the catheter has completely entered the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel for infusion therapy.

But the deficiency that exists in the prior art:

The difference between the indwelling needle and the traditional infusion needle is that it can temporarily retain the needle part in the patient's body, and it is also convenient for the patient to infuse again. The matching protective cover causes the joint part to be exposed to the external environment for a long time while the patient is waiting for the infusion. At this time, the pollutants carried in the air will adhere to the joint.

Therefore, we have proposed an anti-pollution protective sheath for indwelling needles, so as to solve the above-mentioned problems.

Utility model content

The purpose of this utility model is to provide an anti-pollution protective cover for indwelling needles. Since there is no protective cover matching the joints of indwelling needles in the prior art, the joints of patients are exposed to the external environment for a long time during the time when the patient is not infused. In the process, the pollutants in the air will be attached to the joints.

In order to achieve the above purpose, the utility model provides the following technical solutions: an anti-pollution protective sheath for indwelling needles, comprising: a sheath body, the outer wall of the sheath body is cut with an inner cloth groove, and the inner cloth groove A metal slide bar is fixedly inserted between the two sides of the inner wall of the metal slide bar. The outer wall of the metal slide bar is movably covered with a rigid cloth frame. The outer wall of the cloth frame is provided with a transparent cover, and the outer wall of the sheath body is cut with a cloth storage groove, and the size of the cloth storage groove is equal to that of the extended cloth block.

Preferably, two cloth holes are opened inside the extending cloth, and metal buttons are provided on the inner and outer walls of the two cloth holes.

Preferably, two predetermined holes are arranged inside the cloth storage groove, and magnetic rings are arranged on the inner surface walls of the two predetermined holes, and the diameters of the two magnetic rings are equal to metal buttons.

Preferably, two rubber joints are adhered to the outer wall of the sheath body by glue, and a track groove is opened inside one of the two rubber joints.

Preferably, a toothed belt is fixedly installed on the outer wall of one of the two rubber joints, and the outer wall of the toothed belt is movably inserted into the track groove.

Preferably, the outer wall of one of the two rubber joints is provided with an outer slot, and a movable insert is movably inserted inside the outer slot, and the thickness of the movable insert is the same as that of the two teeth on the rubber joint. Teeth are equally spaced.

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

1. In this practical model: when the indwelling needle is inserted into the patient's body, the joint part connected with it will stay on the patient's skin surface. While the patient is waiting for the infusion, the sheath body is put on the patient's arm at this time, and the patient is observed. The position of the joint part is such that it can be placed inside the inner cloth groove, and the extended cloth block is pulled, and the flexible connection between the metal slider and the rigid cloth frame is used to finally make the rigid cloth frame cover the inner cloth groove. At the same time, the joint protruding from the patient's skin surface is stored inside the transparent cover. When the product is in use, the infusion tube connected to the joint can be pressed by adjusting the tightening degree of the sheath body. The effect of elasticity can lift the joint to prevent the joint from sticking to the patient's skin for a long time, effectively solving the problem in the prior art that harmful bacteria in the air are attached to the joint due to the inability to protect the joint of the indwelling needle, preventing The bacteria attached to the joint will enter the blood vessels of the patient with the flow of the liquid during the next infusion, reducing the probability of infection of the patient.
