Description

Upper limb deep vein catheterization support

Technical Field

The utility model belongs to the field of medical appliances, and relates to a support, in particular to a support for upper limb deep vein catheterization.

Background

The upper limb deep vein catheterization is suitable for patients who have long-term venous transfusion, repeated blood transfusion, transfusion of irritant or high-viscosity blood products and repeated blood collection, and is a life passage for rescuing critical patients. The medical technology is widely applied to clinic, in the clinical treatment process, the PICC is used for catheter placement, the basilic vein is selected firstly during catheter placement, the basilic vein is positioned on the inner side of the upper limb of a human, and during catheter placement, the basilic vein on the inner side of the upper limb needs to be fully exposed by a patient to form a needle insertion plane, so that the operation of a nurse is facilitated, and the times of puncture failure are reduced. However, some elderly patients have skin laxity due to aging, especially those with relatively thin and weak age, even if the upper limbs are laid flat, the patient cannot fully expose the valuable veins to form a plane which is easy to insert the needle because the amount of subcutaneous fat is small and the skin is loose, so that the fat falls downwards.

In the prior art, due to the existence of the problems, two nurses are usually matched, the upper limb is padded below the upper limb of the patient by a cloth ball or other soft objects, so that the fat of the upper limb of the patient can be lifted, the valuable vein is fully exposed, one nurse fixes the upper limb of the patient, and the other nurse performs needle puncture, which wastes manpower. And because the catheterization usually takes about 30 minutes, and unconscious patients can not always keep the inner side of the upper limb exposed, great inconvenience is brought to the puncture, the patients are suffered from pain caused by multiple punctures due to insufficient exposure, and complications are easily caused by the multiple punctures, so that the risk is increased for the treatment of the patients.

SUMMERY OF THE UTILITY MODEL

For solving exist among the prior art more than not enough, the utility model aims at providing a dark vein catheterization of upper limbs supports and holds in palm to reach the help patient and fully expose the important vein and form the needle plane of inserting, use manpower sparingly, improve the puncture success rate, alleviate the painful and purpose that reduces the puncture complication of patient.

In order to achieve the above object, the utility model adopts the following technical scheme: the upper limb deep vein catheterization support comprises a first bracket and a second bracket which are padded below an upper limb and used for clamping the upper limb, wherein the first bracket comprises a bottom plate contacted with the bottom surface of the upper limb and a baffle plate fixedly arranged on the bottom plate and used for preventing fat on one side of the upper limb, which is far away from a trunk, from expanding outwards, and the baffle plate is arranged along the length direction of the upper limb; the second bracket is provided with a fixing part which enables the second bracket to move towards the direction close to or far away from the baffle, and one surface of the second bracket, which is contacted with the fat on one side of the upper limb close to the trunk, is an inclined surface.

Detailed Description

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It is to be understood that the upper extremity deep vein catheterization support tray described herein is a preferred embodiment, is provided for purposes of illustration and explanation only, and is not to be construed as a limitation of the present invention.

Example the deep vein of upper limbs puts the pipe and supports and hold in the palm

In this embodiment, as shown in fig. 1, 2 and 3, the upper limb deep vein catheterization support bracket comprises a first bracket 1 and a second bracket 2 which are padded under the upper limb and used for clamping the upper limb, wherein a clamping groove for placing the upper limb is formed between the first bracket 1 and the second bracket 2, and is used for gathering the fat of the upper limb and forming a plane for facilitating catheterization and needle insertion. First bracket 1 and second bracket 2's material is the cotton or silica gel of softer memory, and this embodiment adopts the memory cotton, and the patient is comparatively comfortable when putting the upper limbs on, and manufacturing cost is lower, and the junction of first bracket 1 and second bracket 2, the stupefied department in limit are the chamfer transition, in the use, increase patient's comfort.

First bracket 1 includes bottom plate 1.1 and baffle 1.2, bottom plate 1.1 is placed on patient's sick bed, arranges patient's upper limbs in during the use on bottom plate 1.1, makes bottom plate 1.1 play the supporting role to patient's upper limbs, set firmly baffle 1.2 that is used for preventing the upper limbs to keep away from the fat of truck one side and expands outward on bottom plate 1.1, baffle 1.2 is perpendicular with bottom plate 1.1 to the length direction along the upper limbs sets up. As shown in fig. 2, the bottom plate 1.1 and the baffle plate 1.2 are L-shaped in cross section.

The upper portion (figure 3 upper portion) cross-section of second bracket 2 is right trapezoid, and lower part (figure 3 lower part) cross-section is the rectangle, wherein, the one side that second bracket 2 and upper limbs are close to the fat contact of truck one side is inclined plane 2.1 in the right trapezoid, contained angle between inclined plane 2.1 and the horizontal plane is 50 degrees, inclined plane 2.1's setting, and when patient's fat was held up, can play buffering or transitional effect, increase patient's travelling comfort.

Be equipped with on the second bracket 2 and make second bracket 2 to being close to or keeping away from the fixed part of baffle 1.2 direction motion, the fixed part of this embodiment is the recess 2.2 that sets up on 2 rectangular cross sections of second bracket, recess 2.2 runs through whole second bracket 2, bottom plate 1.1 and the recess 2.2 of first bracket 1 mutually support, and plug in recess 2.2, make second bracket 2 can follow bottom plate 1.1 side-to-side movement. When the fat of the upper limb of the patient is less, the second bracket 2 is moved to the direction close to the baffle 1.2; when the fat of the upper limb of the patient is more, the second bracket 2 is moved away from the baffle 1.2, so that the device can be suitable for more patients. The recess 2.2 of the present embodiment is provided at the lower part of the second bracket 2, and the side of the recess 2.2 located below the bottom plate 1.1 (below in fig. 3) is thin, so that the bottom of the first bracket 1 and the second bracket 2 is kept as flat as possible when they are used in cooperation. One side that bottom plate 1.1 was not equipped with baffle 1.2 sets firmly the fixture block 3 that prevents second bracket 2 along upper limbs length direction motion, fixture block 3 is equipped with two, is located bottom plate 1.1 around (back before figure 2) both ends respectively, is used for two terminal surfaces of joint second bracket 2 promptly, prevents that second bracket 2 from moving around (around figure 1) along bottom plate 1.1 length direction.

The height of baffle 1.2 of this embodiment is 10cm, and length is 25cm, and the length of the bottom plate 1.1 of being connected with it also is 25cm promptly, and the height of the second bracket 2 of 1.1 complex with the bottom plate is 10cm, and length is 25cm, accords with ergonomic, and is close with the height of normal adult's upper limbs, and reasonable size design more conveniently takes in the use, is favorable to the nurse to put the pipe.

When the device is used, the bottom plate 1.1 of the first bracket 1 is inserted into the groove 2.2 of the second bracket 2, then the upper limb of a patient is placed in the clamping groove formed by the baffle plate 1.2 and the inclined surface 2.1, the upper limb of the patient is placed on the bottom plate 1.1, the distance between the baffle plate 1.2 and the inclined surface 2.1 is adjusted, so that the basilic vein of the patient is fully exposed, a plane easy for catheterization is formed, and then the deep venipuncture catheterization is performed on the patient.
