Arm nursing device for hemodialysis puncture

Abstract

The invention discloses an arm nursing device for hemodialysis puncture, and relates to the technical field of medical instruments. The arm nursing device for hemodialysis puncture comprises two reinforced nylon connecting blocks, a connecting cover is movably connected between the two reinforced nylon connecting blocks, an operation opening is formed in the surface of the connecting cover in a penetrating mode, and placing holes are formed in the middles of the two reinforced nylon connecting blocks in a penetrating mode. According to the arm nursing device for hemodialysis puncture, a worker can conveniently insert a needle, the arm of a patient is sleeved with the reinforced nylon connecting block and the connecting cover, the device can be driven to move in the displacement direction of the arm of the patient, a certain degree of activity space is achieved while hemodialysis is conducted on the patient, the arm nursing device can adapt to catheters of different specifications, and operation is convenient. And meanwhile, through limiting of a first limiting block and a second limiting block, the guide rails are fixed conveniently, meanwhile, the guide pipes are not prone to being wound together, and operation of workers is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an arm care device for hemodialysis puncture. Background technique [0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body, and passes through a dialyzer composed of countless hollow fibers. The whole process of exchanging substances with the principle of convection, removing metabolic waste in the body, maintaining electrolyte and acid-base balance; at the same time removing excess water in the body, and returning the purified blood is called hemodialysis. [0003] Patent Publication No. CN 109602558 A discloses a new type of nursing device for hemodialysis puncture, including a fixing seat, an open-source single-chip microcomputer and an adjusting mechanism are installed on the top of the fixing seat, and an arm support seat is fixed at the end of the...

[0003] Patent Publication No. CN 109602558 A discloses a new type of nursing device for hemodialysis puncture, including a fixing seat, an open-source single-chip microcomputer and an adjusting mechanism are installed on the top of the fixing seat, and an arm support seat is fixed at the end of the adjusting mechanism. The arm support seat is connected with a transparent shield through a clamping mechanism. The transparent shield is a U-shaped structure. This new type of nursing device for hemodialysis puncture protects the puncture site through the transparent shield to avoid touching the puncture needle, ensuring the safety of nursing care. Safety, adjust the working position of the arm support seat through the adjustment mechanism, which has good flexibility and strong adjustment ability, and is convenient to meet different use needs. The transparent shield and the arm support seat are assembled through the snap-in mechanism, and its installation and disassembly Convenient, easy to separate the transparent shield from the arm support seat, so that it is convenient to place the arm, the arm support seat is an arc-shaped structure, which is easy to fit the arm, but when the device is in use, the patient's arm is attached to the device for a long time At this time, the arm is likely to be oppressed by the transparent shield and the arm support seat for a long time, and due to the metabolism of the human body, moisture will be generated between the arm and the device, which will easily cause the arm to sweat and bring discomfort to the patient. The fixation effect on the puncture catheter is poor, and it is impossible to comb the puncture catheter, which is not convenient for medical staff to perform subsequent extubation or intubation. If the patient turns over, it is easy to pull the puncture catheter, which will not only affect the medical effect, but also make the puncture needle Deviation occurs, safety accident occurs
