Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of upper arm venous catheter placement support frames, in particular to an upper arm central venous catheter placement support frame with a fixing function. Background Art
[0002] During PICC and arm port insertion, nurses usually perform the operation at the bedside. The patient lies flat on the bed with the arm abducted to 90 degrees. The nurse performs a series of operations such as preoperative preparation, puncture, and tube positioning. This takes a long time. If puncture and tube delivery are difficult, the time will be even longer. During this process, the patient's arm is always in an abducted position, and the patient's elbow and forearm are completely suspended outside the bed. After the puncture, the patient has arm soreness, numbness in the extremities and other discomforts. At the same time, because the patient cannot strictly maintain the limb position, the needle insertion angle is affected. During the operation, the phenomenon of sagging arm skin is more common in the elderly and some special patient groups, which will lead to changes in the position of blood vessels, making it difficult for medical staff to accurately find the ideal tube insertion position, increasing the difficulty of tube insertion, and reducing the success rate of tube insertion puncture;
[0003] Suturing the incision of an arm infusion port is a common surgical procedure in clinical practice. The effects of sagging skin on the incision suture include: difficulty in incision apposition: the skin on both sides of the incision is often difficult to apposition naturally, resulting in the need for additional adjustment of skin tension during the suturing process, which increases the difficulty of the operation; decreased suture quality: the sutured incision is prone to complications such as scar hyperplasia, rupture or infection; poor postoperative recovery: the postoperative recovery time is long, and the skin around the incision is loose and deformed, affecting the appearance;
[0004] In order to solve the above problems, an upper arm central venous catheterization support frame with a fixing function is proposed. Utility Model Content
[0005] In response to the above technical problems, the utility model provides an upper arm central venous catheterization support frame with a fixing function, which is characterized by comprising a bottom plate, a limiting groove, an elastic band, a slide, a connecting block, a tightening bolt, a grip ring, and a sponge pad. The bottom plate is provided with a limiting groove, an elastic band is provided in the limiting groove, a slide is provided on the bottom plate, a connecting block is provided in the slide, a tightening bolt is provided below the connecting block, a grip ring is provided above the connecting block, and a sponge pad is provided on the bottom plate;
[0006] Furthermore, one end of the bottom plate is semicircular, and the other end is long. The limiting groove is located at one end of the long bottom plate. There are two limiting grooves, one on each side of the bottom plate. The elastic band is set in the limiting groove by Velcro.
[0007] Furthermore, the slide groove is located at the front end of the elastic band, the slide groove passes through the bottom plate, and there is a convex strip on each of the two inner walls of the slide groove, with a gap between the two convex strips, the connecting block is located above the two convex strips, and the lower end of the connecting block has a threaded opening, the tightening bolt passes through the gap between the two convex strips and is connected to the connecting block by a thread, and a grip ring is fixed on the connecting block;
[0008] Furthermore, the sponge pad is arranged at one end of the long strip of the bottom plate through a rope, the sponge pad is located at the rear end of the elastic band, and the upper and lower surfaces of the bottom plate are symmetrically arranged.
[0009] Beneficial effects of the utility model:
[0010] The utility model provides support by completely placing the patient's arm on the base plate, preventing the arm from hanging outside the bed, making the patient's arm feel comfortable when in use; by placing the patient's upper elbow arm on the puncture side above the sponge pad, the skin at the puncture site is completely exposed, the skin's firmness is improved, and it is convenient for puncture; the elastic band is installed in the limiting groove of the base plate by Velcro through the patient's lower elbow arm to prevent movement during injection; the patient's hand grasps the grip ring on the connecting block to make the veins more filled, making puncture convenient; at the same time, the patient's hand holds the grip ring, which is equivalent to holding hands, alleviating the patient's fear and anxiety; the arm bracket and sponge pad are used under the upper elbow arm to improve skin tension, reduce the difficulty of suturing, and reduce the risk of scar hyperplasia and rupture. It can be reversed left and right and is suitable for left and right hands; the sponge pad, Velcro and elastic band are all disposable consumables with a low chance of infection.
