Description

Forearm indwelling needle fixing sleeve

Technical Field

The utility model relates to a keep somewhere fixed cover of needle, concretely relates to fixed cover that needle was kept somewhere to forearm.

Background

At present, the fixing devices of the vein indwelling needle are very many, the fixing sleeve of the forearm indwelling needle is less, and in addition, the fixing of the forearm indwelling needle is more difficult than the hand fixing, because the arm does not have a convenient fixing position.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a be convenient for fixed, and can stabilize fixed needle of keeping somewhere, use simultaneously and observe very convenient fixed cover of keeping somewhere needle.

A forearm indwelling needle fixing sleeve is characterized by comprising a hard sleeve, wherein the hard sleeve is a shell made of transparent plastic, a front elastic connecting sleeve is fixed at the front end of the hard sleeve, a rear elastic connecting sleeve is fixed at the rear end of the hard sleeve, fixing belts are fixed at the ports of the rear elastic connecting sleeve and the front elastic connecting sleeve, and the fixing belts are used for positioning with a forearm;

the fixing clamp is fixed on the inner top surface of the hard sleeve and used for fixing the infusion tube, a disposal hole is formed in the hard sleeve, the disposal hole is hinged to the observation window, the fixing clamp is also fixed on the inner surface of the observation window, and when the observation window is opened, the heparin cap of the infusion tube can be exposed.

Furthermore, the bottom surface of the hard sleeve is fixed with a plurality of lower contact blocks which are spaced 2-4cm from each other, the top surface of each lower contact block is a cylindrical surface and used for placing an arm, two ends of the top surface of the hard sleeve are respectively fixed with an upper contact block, and the bottom surface of each upper contact block is also a cylindrical surface and used for accommodating the arm.

Preferably, the casing is in the shape of a cone, or the bottom of the longitudinal section is a rectangle, the upper part of the longitudinal section is a circular arc, and the circular arc part is a semi-cone.

Furthermore, the elastic belts are fixed in the hard sleeve and parallel to the width direction of the hard sleeve, the upper sides of the lower contact blocks and the lower sides of the upper contact blocks are fixed in parallel in pairs, and the pairs of elastic belts are fixed in the length direction of the hard sleeve.

Preferably, the upper and lower contact blocks are made of hard plastic blocks, or made of gel, or soft gaskets are fixed on the surfaces of the hard plastic blocks.

Preferably, the front elastic connecting sleeve and the rear elastic connecting sleeve are provided with ports or a binding port made of hook and loop fasteners.

Preferably, the opening direction of the observation window is parallel to the length direction of the hard sleeve.

The utility model has the advantages that the indwelling needle can be stably fixed, meanwhile, the indwelling needle is prevented from being directly exposed in the environment, the contact between the indwelling needle and clothes and the like is reduced, the position stability is ensured, and the indwelling needle is prevented from shifting and falling off due to rubbing caused by scraping;

the friction between the needle handle of the infusion tube and the skin is reduced, and the comfort level is improved;

reduce the use of adhesive tape, the adhesive tape is generally directly pasted on skin, and skin comfort level is very poor on the one hand, and partial disease is allergic easily, and on the other hand drops easily after sweating, and this fixed cover is not suitable for the adhesive tape basically, improves the comfort level, and is fixed more stable.

In the figure, an arm 10, a hard sleeve 20, a rear elastic connecting sleeve 21, a front elastic connecting sleeve 22, a lower touch block 23, an upper touch block 24, an observation window 25, a fixing clip 26, an elastic belt 27 and a transfusion tube 30

Detailed Description

The following describes the present invention in detail with reference to the accompanying drawings.

As shown in fig. 1-4, a forearm indwelling needle fixation sheath, which comprises a hard sheath 20, wherein the hard sheath 20 is a casing made of transparent plastic, the casing may be in the shape of a cone, or the bottom of the longitudinal section is a rectangular upper part which is a circular arc, the circular arc part is a half cone, the front end of the hard sheath 20 is fixed with a front elastic connection sleeve 22, the rear end is fixed with a rear elastic connection sleeve 21, the elastic connection sleeves are made of elastic cloth, the end ports of the rear elastic connection sleeve 21 and the front elastic connection sleeve 22 are fixed with fixing bands which are elastic bands or band bands capable of shrinking and expanding, the bottom of the hard sheath 20 is fixed with a plurality of lower contact blocks 23, the lower contact blocks 23 are spaced 2-4cm apart from each other, the top of the lower contact block 23 is a cylindrical surface for placing an arm, the two ends of the top of the hard sheath 20 are respectively fixed with an upper contact block 24, and the bottom of the upper, the fixing clamp 26 is fixed on the inner top surface of the hard sleeve 20 and used for fixing the infusion tube 30, a disposal hole is formed in the hard sleeve 20, the disposal hole is hinged with the observation window 25, the fixing clamp 26 is also fixed on the inner surface of the observation window 25, and when the observation window 25 is opened, the heparin cap of the infusion tube can be leaked.

Because the fixed cover will be fit for different user's arm, consequently, set up the elasticity adapter sleeve, what stereoplasm cover 20 can do like this is a little shorter, fixes at wrist and elbow with the elasticity adapter sleeve, and the soft or hard cooperation can effectual adaptation arm of different length like this. In addition, the inner diameter of the hard sleeve is slightly larger, the upper and lower touch blocks are utilized to prevent the infusion tube from touching the hard sleeve 20, in addition, in order to improve the use comfort, the elastic band 27 is fixed in the hard sleeve 20, the elastic band 27 is parallel to the width direction of the hard sleeve, the elastic band is fixed in pairs in parallel at the upper side of the lower touch block 23 and the lower side of the upper touch block 24, and the paired elastic bands 27 are fixed in pairs in the length direction of the hard sleeve 20.

The upper and lower contact blocks can also be made of hard plastic blocks or gel, or soft gaskets are fixed on the surfaces of the hard plastic blocks. The size of the binding opening can be adjusted by using the binding openings made of hook and loop fasteners at the ports of the front elastic connecting sleeve 22 and the rear elastic connecting sleeve 21 or the binding openings.

The opening direction of the observation window 25 is parallel to the length direction of the hard sleeve 20, so that the needle of the infusion tube 30 is not driven to swing. The observation window 25 can be fixed by using a magnet, the magnet or a patch is fixed at the open end of the observation window, and the patch or the magnet mutually attracted with the hard sleeve is fixed at the corresponding position of the hard sleeve.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and those skilled in the art can make various modifications and variations. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
