Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an adjustable upper limb fixing frame. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. When patients undergo dialysis treatment, one dialysis session usually lasts for several hours or even longer. During this process, most hospitals currently use traditional adhesive tape fixation methods, and the patient's arm needs to remain in one position for a long time. During dialysis, unconscious movements after sleeping or slight turning over of the patient may cause the dialysis tube to fall off and the needle to shift, thereby causing the dialysis puncture needle to detach from the blood vessel and blood to extravasate, greatly increasing the patient's pain. Moreover, after being fixed, the patient's hand is in an unnatural physiological state for a long time, which is prone to stiffness and very uncomfortable. In addition, when the elbow joint is fractured and dislocated and needs to be fixed, an upper limb fixation device is also needed to fix the angle between the upper arm and the forearm to prevent secondary injury to the elbow joint.

[0003] The utility model with announcement number CN216394298U discloses an adjustable upper limb fixing device, including a first support rod fixedly connected to the upper arm of a human body, a second support rod fixed to the forearm, and a fixing sleeve, the first support rod and the second support rod being connected by an angle control device, the fixing sleeve being composed of a rigid plate and a flexible connecting belt arranged between the rigid plates, the outer peripheral surfaces of the first support rod and the second support rod being provided with sliders slidably connected to the rod body along the axial direction, the sliders being fixedly connected to the rigid plate, the first support rod and the second support rod being evenly provided with positioning grooves along the axial direction on the side away from the fixing sleeve, and the sliders being installed with a locking device used in conjunction with the positioning grooves.

[0004] When using the above technical solution, it is difficult to fix the patient's upper arm and forearm at the same time, and it is also difficult to adjust the upper arm and forearm to a comfortable angle when bending. Secondly, when the patient wears the device for a long time, it is easy for the device to cause long-term abrasion of the skin.

[0005] In view of the above problems, the utility model provides an adjustable upper limb fixing frame. Utility Model Content

[0006] The purpose of the utility model is to provide an adjustable upper limb fixation frame. The utility model can make the patient's upper arm and forearm bend and stretch comfortably in accordance with the patient's elbow angle through the setting of the mobilizer. Secondly, the soft pad can also reduce the abrasion of the patient's skin when wearing the device for a long time, thereby solving the problems in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable upper limb fixation frame, comprising a first protective ring, a connecting belt fixedly connected to one side of the first protective ring, a movator fixedly connected to the front of the connecting belt, a threaded rod threadedly connected to the front of the movator, a rotating valve threadedly connected to one end of the threaded rod, a spring fixedly connected to the inside of the first protective ring, a cushion fixedly connected to one end of the spring, and a second protective ring fixedly connected to one end of the connecting belt.

[0008] Furthermore, a strap is fixedly connected to the other side of the first protective ring, and a sub-Velcro is fixedly connected to the front side of the strap, thereby achieving a sticking effect.

[0009] Furthermore, a female Velcro is fixedly connected to the top of the second protective ring, and an air bag is fixedly connected to the inside of the second protective ring, thereby achieving an inflation effect.

[0010] Furthermore, a trachea is fixedly connected to one side of the airbag, and a deflation cover is sleeved on one end of the trachea, thereby achieving a protective effect.

[0011] Furthermore, a button is slidably connected to one side of the front side of the movable device, and a U-shaped ring is fixedly connected to the top of the female Velcro, thereby achieving a placement effect.

[0012] Furthermore, an interception line is fixedly connected to the inside of the U-shaped ring, and one end of the interception line is fixedly connected to a fixing block, thereby achieving a fixing effect.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model provides an adjustable upper limb fixing frame.

[0015] (1) Through the setting of the movable device and the threaded rod, a rotation effect is achieved during use. When the patient's upper arm and forearm are bent, they can be adjusted to better match the patient's posture, avoiding pulling on the patient's injured part when the patient's arm is bent, thereby improving the effect of better fitting the patient's arm.

[0016] (2) Through the setting of springs and cushions, a protective effect is achieved during use. When patients wear the device for a long time, it is easy for the patient's skin to rub and cause abrasion. The cushion can better protect the patient's arm, avoid further injury, and improve the protective effect. BRIEF DESCRIPTION OF THE DRAWINGS
