Description

Lower limb traction belt

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a lower limb traction belt.

Background

Traction is the most common treatment method in an orthopedic ward, and mainly applies the principle of acting force and reacting force to resist the tension and retraction of soft tissues, so that the fracture or dislocation can be reduced, and the deformity can be prevented and corrected. Even today, when internal and external fixation is highly developed, distraction remains an indispensable step after surgery and an important component of treatment planning.

Generally, traction needs to be manually given, and traction is performed by binding a traction belt on the leg of a patient. However, the existing traction belt has the following disadvantages: 1. the material is easy to slip off; 2. skin is easy to be pressed and loosened inconveniently; 3. pediatric skin traction uses hospital adhesive tape, resulting in allergies and skin tears; 4. the infant can not initiatively inform medical personnel when the traction belt slips off, and the treatment effect is easily influenced when the traction belt is in a slip state for a long time.

Detailed Description

The following description and examples detail certain exemplary embodiments of the disclosed invention. Those skilled in the art will recognize that there are numerous variations and modifications of the present invention encompassed by its scope. Accordingly, the description of a certain exemplary embodiment should not be taken as limiting the scope of the utility model.

The embodiment is as follows:

referring to fig. 1 to 3, the present invention provides a lower limb traction band, comprising an upper leg sleeve 1, a lower leg sleeve 2, and a first connecting band 3 of adjustable length connected between the upper leg sleeve and the lower leg sleeve, an upper filling part 4 being attached to the inner surface of the upper leg sleeve, a lower filling part 5 being attached to the inner surface of the lower leg sleeve, the upper leg sleeve and the lower leg sleeve being respectively configured to allow gas to be filled;

An air pressure sensor 6 is arranged in the upper filling part, an alarm module 7 is attached to the outer surface of the upper leg sleeve, the alarm module is electrically connected to the air pressure sensor, and the alarm module is configured to give an alarm when the air pressure in the upper filling part sensed by the air pressure sensor is smaller than a set value.

In this embodiment, the upper leg cuff is provided with an upper fixing strap 8 configured to tighten the upper leg cuff on the thigh.

In this embodiment, the lower leg cuff is provided with a lower securing strap 9 configured to secure the lower leg cuff to the lower leg.

Wherein, the magic subsides are all selected for use to go up fixed band and lower fixed band. Above fixed band is the example, and it is including setting up the first area body and the second area body of setting at last leg cover opposite side in last leg cover one side, be provided with the hook face that the magic was pasted on the first area body, be provided with the matte that the magic was pasted on the second area body, the first area body and second area body pass through the hook face and the matte firmly pastes together. In order to improve the firmness and stability of the upper leg sleeve, for example, three groups of upper fixing belts which are arranged at equal intervals can be adopted. The structure and the arrangement mode of the lower fixing band are consistent with those of the upper fixing band.

In this embodiment, the inner surface of the upper leg cover is further provided with an upper pad 10, an upper pocket portion with an upward opening is formed between the upper pad and the inner surface of the upper leg cover, and the upper filling portion is detachably placed in the upper pocket portion.

In this embodiment, the inner surface of the lower leg cuff is further provided with a lower pad 11, a lower pocket portion with an upward opening is formed between the lower pad and the inner surface of the lower leg cuff, and the lower filling portion is detachably placed in the lower pocket portion.

The upper liner and the lower liner are breathable sponge mats, are breathable and soft, and can improve wearing comfort. For older children, the upper filling part, the lower filling part and the alarm module can be omitted. The legs of the older children are larger, so the traction belt can be firmly fixed on the lower limbs only by the pad; and as the older children have self-help awareness, the children can inform medical personnel when the traction belt accidentally slips off, and an alarm module is not needed for assisting monitoring. For the infant, since the leg circumference is small, it is not possible to secure the traction band firmly to the lower limb only by the pad, and at this time, it is necessary to prevent the filling portion between the pad and the inner surface of the leg cuff, and the traction band is firmly secured to the lower limb by inflating the filling portion. And because the infant does not have the independent consciousness, the infant cannot actively inform medical care personnel when the traction belt slides down, and the auxiliary monitoring of the alarm module is needed. The alarm module judges whether the traction belt slides down or not by reading the air pressure value in the upper filling part detected by the air pressure sensor, when the traction belt slides down, the extrusion force of the leg to the upper filling part is reduced, so that the air pressure in the upper filling part is reduced, and when the air pressure is reduced to a set value, the alarm module gives an alarm to remind medical personnel to wear the traction belt for the infant again. The working principle of the air pressure sensor and the alarm module is disclosed in detail in chinese utility model patent CN214474679U, and therefore it is a prior art well known to those skilled in the art and will not be described herein.

In this embodiment, the upper filling portion and the lower filling portion are both air bags, and valves 12 for inflating the interiors of the air bags are arranged on the air bags, so that the air bags are inflated or the air in the air bags is discharged through the valves.

In this embodiment, referring to fig. 4, the alarm module includes a housing 13, a PCB 14 disposed in the housing, and a control chip 15, an alarm unit 16 and a power supply 17 integrated on the PCB, and the air pressure sensor is electrically connected to the PCB. The alarm unit is a buzzer, the power supply is a lithium battery, and the control chip is an MCU (microprogrammed control unit).

In this embodiment, a pedal 18 is included for placement at the foot plate, said pedal being secured to the lower leg cuff via a second connecting strap 19 of adjustable length.

The first connecting band and the second connecting band of the utility model are similar to the structure of the schoolbag shoulder strap, and the length adjusting principle is consistent with the length adjusting principle of the schoolbag shoulder strap, thus not being described in detail.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to the above-described embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
