Description

Auxiliary fixator for indwelling needle in arm

Technical Field

The utility model relates to the technical field of auxiliary fixers for indwelling needles, and more specifically to an auxiliary fixer for indwelling needles in arms.

Background technique

At present, safe indwelling needles have been widely used in clinical practice. Compared with traditional infusion needles, indwelling needles can reduce the number of punctures, prolong the retention time, protect blood vessels, reduce the pain of patients, and improve the work efficiency of medical staff. The core components of common indwelling needles include a soft catheter that can be retained in the blood vessel and a stainless steel puncture guide needle core.

There are many existing technologies for auxiliary fixators of indwelling needles, such as:

Chinese patent publication number CN204446807U discloses an infusion medical auxiliary device, and particularly relates to an indwelling needle fixing sleeve, including a fixing sleeve and a fixing connecting belt located on both sides of the fixing sleeve, the fixing sleeve is divided into upper and lower parts, the upper part is a movable flap, and the lower part is a fixing sleeve body, and the bottom end of the movable flap is connected with the top end of the fixing sleeve body by seams. The outer surface of the movable flap is provided with an identification plate insertion pocket, and the outer side surface of the fixing sleeve body that does not contact the human body is provided with a fixing device and a card slot for fixing the three-way catheter of the indwelling needle. When the movable flap is turned down, it overlaps with the fixing sleeve body. The fixing connecting belt is provided with an elastic section, and a connecting structure is provided at the end. The utility model has a simple structure and is easy to manufacture. It can fix the indwelling needle conveniently and quickly, has a good fixing effect, is not easy to fall off, and does not need to remove the fixing sleeve for the next infusion. The contact area with the arm is small, and after long-term fixation, it causes little damage to the skin.

It can be seen that when the indwelling needle is in use, it is necessary to fix the indwelling needle on the user's arm. However, if adhesive tape is used, since the indwelling needle needs to be retained for a long time, human skin secretions will cause the adhesive tape to decrease, thereby loosening the fixation of the indwelling needle. However, when using a fixing sleeve, due to the different injection positions of the indwelling needle, some indwelling needles are injected on the side of the palm, resulting in the need to turn the palm sideways when using the fixing sleeve. The fixing sleeve with the palm sideways will exert a compressive force on the palm, causing the palm to bend, which is uncomfortable for the patient. Long-term bending of the palm will cause cramps, and cramps and shaking will cause the fixation of the indwelling needle to loosen, affecting the therapeutic effect of the indwelling needle.

In view of this, the utility model provides an auxiliary fixer for an arm indwelling needle.

Detailed ways

When the indwelling needle is in use, it is necessary to fix the indwelling needle on the user's arm. However, if adhesive tape is used, since the indwelling needle needs to be retained for a long time, human skin secretions will cause the stickiness of the tape to decrease, thereby loosening the fixation of the indwelling needle. However, when using a fixing sleeve, due to the different injection positions of the indwelling needle, some indwelling needles are injected on the side of the palm, resulting in the need to turn the palm sideways when using the fixing sleeve. The fixing sleeve with the palm sideways will exert a compressive force on the palm, causing the palm to bend, which is uncomfortable for the patient. Long-term bending of the palm will cause cramps, and cramps and shaking will cause the fixation of the indwelling needle to loosen, affecting the therapeutic effect of the indwelling needle.

As shown in Fig. 1-4, the device comprises at least one elbow support and protection pad 11, the elbow support and protection pad 11 is used to support the arm, an arm auxiliary fixing adjustable component 20 is provided on the surface of the elbow support and protection pad 11, the arm auxiliary fixing adjustable component 20 is used to fix the patient's arm indwelling needle, and the arm auxiliary fixing adjustable component 20 can adjust the fixing position laterally to adapt to different indwelling needle placement positions, and the arm auxiliary fixing adjustable component 20 can change the fixing shape by elastic force, an arm support angle rotation component 30 is provided on the surface of the elbow support and protection pad 11, the arm support angle rotation component 30 is used to support the patient's elbow, and can be rotatably supported, so that the patient's palm is supported and placed;

The improvement of this embodiment is that: the patient's arm is fixed by the elbow support and placement of the protective pad 11 and the arm auxiliary fixing adjustable component 20 with a fixing belt, and the shape of the patient's palm is fixed by elastic force, so as to avoid the palm side fixing sleeve from forming a pressing force on the palm, causing the palm to bend, which is uncomfortable for the patient. Long-term palm bending will cause cramps, and cramps and shaking will cause the fixation of the indwelling needle to loosen, affecting the treatment effect of the indwelling needle. The arm elbow is supported by the arm support angle rotation component 30 to avoid the arm being suspended in the air, which will cause the patient's arm soreness and arm shaking for a long time.

The arm auxiliary fixing adjustable component 20 includes a first support belt 21, the first support belt 21 is slidably connected to the elbow support protection pad 11, the surface of the elbow support protection pad 11 is slidably connected to a second support belt 22, and the surfaces of the second support belt 22 and the first support belt 21 are both provided with concave holes;

The arm auxiliary fixing adjustable component 20 includes a first support belt 21, the first support belt 21 is slidably connected to the elbow support protection pad 11, the surface of the elbow support protection pad 11 is slidably connected to the second support belt 22, the second support belt 22 and the first support belt 21 are both provided with concave holes, the surface of the second support belt 22 is provided with a fixing block 23, the fixing block 23 is plugged into the concave hole, the second support belt 22 and the first support belt 21 are fixed together by plugging the fixing block 23 into the concave hole, an elastic block 24 is provided at the bottom of the first support belt 21, and elastic belts 25 are provided on both sides of the elastic block 24;

The support block 33 and the rotating protection pad 31 are slidably connected to limit the moving path of the support block 33. A gear 34 is provided on the surface of the threaded rod 32, and a handle 35 is meshed on the surface of the gear 34. The handle 35 and the rotating protection pad 31 are rotatably connected.

In summary, the working principle of the present solution is as follows: when it is necessary to fix the indwelling needle for treatment in the patient's arm, the patient first places the arm on the elbow support and places the protective pad 11, and the top of the rotating protective pad 31 at the elbow, and then rotates the handle 35 according to the fixed position of the indwelling needle, and the rotation of the handle 35 drives the gear 34 to rotate, and the rotation of the gear 34 drives the threaded rod 32 to rotate, and the rotation of the threaded rod 32 causes the support block 33 to move downward, and the downward movement of the support block 33 causes the rotating protective pad 31 to rotate and support the rotation angle of the threaded rod 32;

Then slide the first support belt 21 and the second support belt 22 inside the elbow support protection pad 11. When sliding to above the indwelling needle, fix the first support belt 21 and the second support belt 22 through the fixing block 23. At the same time, make the elastic block 24 fit the fixing position of the indwelling needle, and the elastic belt 25 is squeezed to generate elastic force to bend, so that the palm remains fixed and avoids bending, thereby completing the fixation of the indwelling needle.
