Description

Technical Field

[0001] This utility model relates to the field of headband fixation technology, and in particular to a headband fixation for a polysomnography monitor. Background Technology

[0002] Polysomnography is an important device for diagnosing sleep-related diseases such as sleep apnea-hypopnea syndrome. During the monitoring process, multiple sensors need to be accurately fixed to the patient's head and corresponding parts of the body to obtain a number of physiological parameters such as electroencephalogram (EEG), electrocardiogram (ECG), airflow through the mouth and nose, and blood oxygen saturation. Therefore, designing a comfortable, stable headband that can ensure the accuracy of monitoring data is of great practical significance.

[0003] However, existing headbands for polysomnography have the following drawbacks: Traditional headbands often use a single elastic band or rigid headband to directly tighten the head, causing local skin indentations, pain, or even ulceration after wearing. At the same time, rigid headbands are difficult to adapt to the natural curvature of the head, resulting in poor fit and a strong foreign body sensation.

[0004] Therefore, this utility model provides a head-mounted fixing sleeve for a polysomnography monitor. Utility Model Content

[0005] (a) Technical problems to be solved The problem solved by this utility model is to provide a highly practical headband for a polysomnography device, which solves the problems mentioned in the background art that cause local skin indentations, pain, or even ulceration after the patient wears the device, and that the rigid fixation strap is difficult to adapt to the natural curvature of the head.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a headband-type fixing sleeve for a polysomnography monitor, comprising a fixing sleeve body, wherein multiple connecting blocks are fixedly connected to the front of the fixing sleeve body, each connecting block has a rectangular through hole on one side, and an elastic band is movably connected to the inner wall of each rectangular through hole, wherein a fixing strap and a soft rubber strip are fixedly connected to both ends of the elastic band, a buckle is fixedly connected to the top of the fixing strap, and multiple locking holes adapted to the buckle are opened at the bottom of the soft rubber strip, wherein the buckle is engaged inside the locking holes.

[0007] Optionally, the inside of the fixing sleeve body is provided with a buffer layer, the material of which is medical gel. The buffer layer evenly disperses the pressure of the headband on the head through the deformation of the gel.

[0008] Optionally, a humidity regulating layer and a temperature regulating layer are sequentially provided on the top of the buffer layer. The humidity regulating layer is made of bamboo charcoal fiber, and the temperature regulating layer is made of phase change material. The humidity regulating layer avoids skin maceration and itching caused by sweat accumulation in traditional fabric headbands, and the temperature regulating layer reduces sleep interruption caused by temperature discomfort.

[0009] Optionally, a soft pad is fixedly connected to one side of the connecting block. The soft pad is made of sponge material. The sponge pad can provide elastic support for the sensor, prevent the sensor from directly impacting the skull due to head movements, and protect the sensor probe from damage.

[0010] Optionally, an identification strip is fixedly connected to the other side of the connecting block. The identification strip is composed of fluorescent strips and is symmetrically arranged. The symmetrical light emission pattern of the fluorescent strips allows for quick confirmation of whether the headband is worn correctly.

[0011] Optionally, the surface of the fixing sleeve body is provided with multiple ventilation holes arranged in a circle. The ventilation holes improve air circulation efficiency and promote sweat evaporation.

[0012] (III) Beneficial Effects This utility model provides a headband-style fixing sleeve for a polysomnography device, which has the following beneficial effects: This polysomnography headband uses an elastic band that provides basic fastening force through elastic deformation, avoiding the hard compression of the head caused by traditional rigid headbands. The snap-fit ​​structure of the buckles and holes enhances the fixation strength and prevents the elastic band from loosening due to the loss of elasticity over long-term use, achieving the dual effect of "flexible fit + rigid locking". The connecting block distributes the tension of the elastic band to multiple contact points, avoiding excessive pressure on a single fixation point and reducing the risk of local skin indentation and redness.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figures 1 to 4 This utility model provides a technical solution: a headband-type fixing sleeve for a polysomnography monitor, including a fixing sleeve body 1. Multiple connecting blocks 2 are fixedly connected to the front of the fixing sleeve body 1. The connecting blocks 2 distribute the tension of the elastic band 3 to multiple contact points. A rectangular through hole is opened on one side of each connecting block 2. The inner sidewall of each rectangular through hole is movably connected to the elastic band 3. The elastic band 3 provides basic fastening force through elastic deformation. Fixing straps 4 and soft rubber strips 5 are fixedly connected to both ends of the elastic band 3, respectively. A buckle 6 is fixedly connected to the top of the fixing strap 4. Multiple locking holes that are adapted to the buckle 6 are opened at the bottom of the soft rubber strip 5. The locking structure of the buckle 6 and the locking holes enhances the fixing strength. The buckle 6 is locked inside the locking hole. The maximum elastic extension DeltaL of the elastic band is 10cm, the elastic elongation rate is 150%, the original length is 20cm, the spacing between the locking holes of the soft rubber strip is d=1cm, and there are a total of 6 locking holes. The inside of the fixing sleeve body 1 is provided with a buffer layer 7. The material of the buffer layer 7 is medical gel. The buffer layer 7 evenly disperses the pressure of the headband on the head through the deformation of the gel. The top of the buffer layer 7 is provided with a humidity regulating layer 8 and a temperature regulating layer 9. The humidity regulating layer 8 is made of bamboo charcoal fiber, and the temperature regulating layer 9 is made of phase change material. The humidity regulating layer 8 avoids skin maceration and itching caused by sweat accumulation in traditional fabric headbands, and the temperature regulating layer 9 reduces sleep interruption caused by temperature discomfort. A soft pad 10 is fixedly connected to one side of the connecting block 2. The soft pad 10 is made of sponge. The sponge soft pad 10 can provide elastic support for the sensor, prevent the sensor from directly hitting the skull due to head movement, and protect the sensor probe from damage. On the other side of the connecting block 2, an identification strip 11 is fixedly connected. The identification strip 11 is composed of fluorescent strips and is symmetrically arranged. The symmetrical light emission pattern of the fluorescent strips allows for quick confirmation of whether the headband is worn correctly. The surface of the fixed sleeve body 1 has multiple ventilation holes arranged in a circle. The ventilation holes improve the air circulation efficiency and promote sweat evaporation.

[0017] In this invention, the working steps of the device are as follows: Step 1: The patient puts the fixation sleeve body 1 on their head, aligning the connecting block 2 with the position where the sensor needs to be placed; pull the elastic band 3 through the rectangular through hole of the connecting block 2, adjusting the tightness of the elastic band 3 according to the head circumference: if the head circumference is large, stretch the elastic band 3 outward to extend the fixation band 4 and the soft tape 5 to a suitable length; if the head circumference is small, contract the elastic band 3 inward to shorten the distance between the fixation band 4 and the soft tape 5; after adjustment, insert the buckle 6 at the top of the fixation band 4 into the hole of the soft tape 5, and fix it by engaging the buckle 6 with the hole to form a closed fixation structure around the head.
