Description

A knee joint restraint belt structure capable of alarming

Technical Field

The utility model relates to the technical field of restraint belts, in particular to a knee joint restraint belt structure capable of providing an alarm.

Background Art

Interventional surgery is a minimally invasive surgery, which generally uses large blood vessels on the body's surface as the puncture point. When patients with cerebrovascular, peripheral vascular, and tumor diseases undergo angiography or interventional treatment, the femoral artery is often punctured. If the patient's knee joint moves during the puncture, it will not only lead to puncture failure, but also greatly increase the risk of bleeding. In particular, patients with cerebrovascular diseases are often accompanied by confusion, restlessness, and are prone to falling out of bed. In addition, in order to prevent bleeding from the puncture site after femoral artery puncture, the limb on the puncture side still needs to be fixed with a restraint belt for a period of time.

Existing restraint belts usually include a continuous, wider belt body, which is wrapped around the knee joint to fix the knee joint when in use, but it cannot effectively prevent the patient's knee from flexing, and it is very easy to cause the puncture sheath to shift or even fall out. If the nurse fails to discover it in time during work, it is easy to cause damage due to long-term bending, which affects the recovery effect after surgery.

Utility Model Content

In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a knee joint restraint belt structure with an alarm, which effectively solves the problem that the existing restraint belt cannot effectively prevent the patient's knee from flexing, which can easily cause the puncture sheath to shift or even fall out. If the nurse fails to discover it in time during work, it is easy to get injured, affecting the recovery effect after surgery.

The technical solution is that the utility model comprises a restraint belt, the left and right sides of the restraint belt are fixedly connected with straps, the upper surface of the restraint belt is movably connected with two I-shaped blocks, the upper surface of the I-shaped blocks is fixedly connected with a knee joint fixing belt, the knee joint fixing belt is formed with a fixed hole through a fixing component, an airbag is installed inside the fixed hole, a pressure sensor, a controller and a button battery are installed inside the airbag, and a buzzer is installed on the outside of the airbag.

Preferably, a buffer layer is provided inside the restraint belt, and the filler in the buffer layer is cotton.

Preferably, both left and right sides of the restraint belt are fixedly connected with fixing blocks, a long hole is opened on the fixing block, and the I-shaped block is slidably connected inside the long hole.

Preferably, the knee joint fixation belt is made of composite elastic fabric.

Preferably, the fixing assembly includes a Velcro fleece surface fixedly connected to one end of the knee joint fixing strap, and the other end of the knee joint fixing strap is fixedly connected to a Velcro sticky surface corresponding to the Velcro fleece surface.

Preferably, the pressure sensor and the buzzer are both electrically connected to a button battery, and the button battery is electrically connected to the controller.

Compared with the prior art, the beneficial effects of the utility model are:

1. Fix the restraint belt to the bed through straps, and then wrap and fix the patient's knee joint in the fixed hole formed by the knee joint fixation belt, so as to effectively limit the bending and abduction of the patient's knee joint, and it is not easy to shift. At the same time, the patient's calf can drive the I-shaped block to slide inside the long hole to perform small translation and ankle pump movements. The elastic knee joint fixation belt and the restraint belt with a buffer layer can be suitable for patients of different body shapes, reduce the patient's sense of restraint, reduce constraint complications, and enhance the comfort of the restraint belt.

2. A transparent airbag is set at the fixed hole formed by the knee fixation belt. When the patient bends the knee joint, the airbag will be squeezed. At this time, the pressure sensor detects the increase in pressure inside the airbag, and the controller makes the buzzer sound an alarm, so that the nurse can find and adjust the patient's knee joint in time. When the patient bends the knee, the alarm can also be sounded to remind the patient, thereby improving the recovery effect after surgery.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Figures 1 to 4 show a knee joint restraint belt structure capable of alarming, including a restraint belt 1, with straps 2 fixedly connected to both left and right sides of the restraint belt 1, two I-shaped blocks 3 movably connected to the upper surface of the restraint belt 1, a knee joint fixing belt 4 fixedly connected to the upper surface of the I-shaped block 3, a fixing hole 6 formed by a fixing component 5 in the knee joint fixing belt 4, an airbag 7 installed inside the fixing hole 6, a pressure sensor 8, a controller 9 and a button battery 10 installed inside the airbag 7, and a buzzer 11 installed outside the airbag 7. The pressure sensor can be an HX711 module, and the buzzer can be an active buzzer or a general passive buzzer.

A buffer layer is arranged inside the restraint belt 1, and the filling material in the buffer layer is cotton. This arrangement is relatively soft, can reduce the stress, and increase the comfort of the patient.

In this arrangement, when the patient bends the knee joint, the airbag 7 will be squeezed. At this time, the pressure sensor 8 detects that the pressure inside the airbag 7 increases, and the controller 9 causes the buzzer 11 to sound an alarm, so that the nurse can find and adjust the patient's knee joint in time.

The technical solution provided by the utility model is to fix the restraint belt 1 to the bed body through the strap 2, then the patient's knee joint is placed in the fixing hole 6 formed by the knee joint fixing belt 4, and then the patient's knee joint is wrapped and fixed through the Velcro fur surface 501 and the Velcro sticky surface 502, so as to effectively limit the bending and abduction of the patient's knee joint, and it is not easy to shift. At the same time, the patient's calf can drive the I-shaped block 3 to slide inside the long hole 102 to perform a small translation and ankle pump movement, and the elastic knee joint fixing belt 4 and the restraint belt 1 with a buffer layer can be suitable for patients of different body shapes, reduce the patient's sense of restraint, reduce restraint complications, and enhance the comfort of the restraint belt;

When the patient bends the knee joint, the airbag 7 is squeezed. At this time, the pressure sensor 8 detects the increase in pressure inside the airbag 7, and the controller 9 causes the buzzer 11 to sound an alarm, so that the nurse can find and adjust the patient's knee joint in time. When the patient bends the knee, the alarm can also be sounded to remind the patient, thereby improving the recovery effect after surgery.
