Description

An arm fixation device for breast cancer surgery

Technical Field

The utility model relates to the field of medical instruments, in particular to an arm fixing device after breast cancer surgery.

Background Art

Breast cancer is one of the most common malignant tumors in women worldwide. Surgical resection is one of the most important methods in the comprehensive treatment of breast cancer, and postoperative care is even more important. After surgery, in order to prevent the accumulation of lymph fluid produced by the stump of the lymphatic vessels, the net water pressure between tissues, the inflammatory exudate caused by post-traumatic stress, and the bleeding in the subcutaneous cavity, drainage tubes are generally placed in the patient's affected chest and armpit after surgery. During the postoperative drainage process, the patient is required to keep the affected upper limb immobilized, avoid large-scale activities that may cause the drainage tube to come out, and keep the drainage tube unobstructed.

In the current drainage process, doctors will add a lot of bursa to the patient's chest wound and wrap it tightly with a bandage or let the patient wear a breast compression elastic bandage to apply pressure to drain the exudate. In order to prevent the patient's affected limb from moving, many patients will also use arm fixation devices to restrict their arms to prevent arm movement from causing displacement of the drainage tube.

The existing arm fixation devices on the market are generally used for patients with arm fractures and arm corrections. They usually include upper and lower arm fixing brackets to limit the placement angles of the upper and lower arms and the angle between the upper and lower arms. For patients after breast cancer surgery, what needs to be limited is the distance between the upper arm and the body to prevent the upper arm from moving forward, backward, inward or outward to touch the drainage tube. There is no need to limit the distance between the upper arm and the forearm, and the patient can still make movements such as raising or lowering the forearm. The existing arm fixation devices have excessive functions and severely limit the patient's movements, which may cause the patient's forearm stiffness, and cannot effectively limit the distance between the patient's upper arm and the body.

Therefore, how to design an arm fixing device that can limit the distance between the patient's upper arm and the patient's body and limit the movement of the patient's arm is a technical problem that needs to be solved.

Utility Model Content

In order to solve the above problems, the purpose of the utility model is to provide an arm fixation device after breast cancer surgery, which solves the problem that the existing arm fixation devices have excess functions and cannot limit the distance between the patient's upper arm and the patient's body.

To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a shoulder limiting protector and an upper arm limiting protector detachably connected to the shoulder limiting protector; the shoulder limiting protector includes a shoulder breathable plate arranged on the outside and adapted to the curvature of the shoulder and a shoulder lining arranged on the inside and fixedly connected to the shoulder breathable plate; the upper arm limiting protector includes an upper arm breathable plate arranged on the outside and adapted to the curvature of the upper arm and an upper arm lining arranged on the inside and fixedly connected to the upper arm breathable plate; fixing buckles are respectively provided at both ends of the inner side of the upper arm lining, and a limiting pad detachably connected to the fixing buckle is also provided on the inner side of the upper arm lining, adjustment belts for connecting to the fixing buckle are provided on the side walls on both sides of the limiting pad, and an inflatable air cushion is provided on the outer surface of the limiting pad.

Furthermore, an adjustable strap 1 for fixing the use position is provided on the outer wall of the shoulder breathable plate, and an adjustable strap 2 is provided on the outer wall of the upper arm breathable plate.

Furthermore, the shoulder lining is provided with a plurality of first ventilation holes, and the upper arm lining is provided with a plurality of second ventilation holes.

Furthermore, the inflatable air cushion is provided with an inflation and deflation interface.

Furthermore, the limiting pad is provided with a through hole penetrating the upper and lower end surfaces of the limiting pad.

The utility model has the following beneficial effects:

1. The utility model is provided with a limiting pad, and the limiting pad is connected to the breathable plate of the upper arm, so that the inner side of the limiting pad is in close contact with the inner side of the patient's upper arm, and the outer side of the limiting pad is in close contact with the patient's body after the inflatable air cushion is inflated, thereby leaving a distance between the patient's upper arm and the patient's body. The patient is unable to move his arm to the inside of the body to squeeze the drainage tube arranged under the patient's affected armpit. The shoulder limiting protector and the upper arm limiting protector are fixed to the patient's shoulder and upper arm position by means of adjustable straps 1 and 2, and the length of adjustable straps 1 and 2 are adjusted to limit the extent to which the patient can move his arm outward, so as to avoid large arm movement causing movement of the drainage tube.

2. The utility model arranges an inflatable air cushion on the outer side of the limiting pad. The expansion degree of the inflatable air cushion can be flexibly changed according to the needs of the patient, and the distance between the upper arm and the body can be changed to prevent the patient from maintaining the same arm posture for a long time and arm stiffness. At the same time, it can also prevent the patient's upper arm from contacting the patient's body, and the utility model is highly practical.

3. The utility model is provided with a shoulder limit protector and an upper arm limit protector, but does not restrict the movement of the patient's forearm. The patient can still perform actions such as bending the forearm, thus avoiding restrictions on the patient's healthy forearm, and is highly practical.

DETAILED DESCRIPTION

The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

As shown in Figures 1-2, the scheme includes a shoulder limiting protector 1 and an upper arm limiting protector 2 detachably connected to the shoulder limiting protector 1; the shoulder limiting protector 1 includes a shoulder breathable plate 11 arranged on the outside and adapted to the curvature of the shoulder and a shoulder lining 12 arranged on the inside and fixedly connected to the shoulder breathable plate 11; the upper arm limiting protector 2 includes an upper arm breathable plate 21 arranged on the outside and adapted to the curvature of the upper arm and an upper arm lining 22 arranged on the inside and fixedly connected to the upper arm breathable plate 21, and the shoulder limiting protector 1 and the upper arm limiting protector 2 can be connected by fastening bolts.

Both ends of the inner side of the upper arm lining 22 are provided with fixing buckles 222, and the inner side of the upper arm lining 22 is also provided with a limiting pad 3 detachably connected to the fixing buckle 222, which is used to limit the distance between the upper arm limiting protective device 2 and the patient's body. The side walls of the limiting pad 3 are provided with adjustment belts 31 for connecting with the fixing buckle 222, and the adjustment belt 31 is provided with an adjustment buckle (not shown) for adjusting the length of the adjustment belt 31, and the outer surface of the limiting pad 3 is provided with an inflatable air cushion 32.
