Description

Adjustable headgear

Technical Field

The invention belongs to the field of medical auxiliary appliances, and particularly relates to an adjustable headgear.

Background

According to statistics, in death caused by traffic accidents, falling accidents, violent accidents and the like, the brain trauma is the most common trauma and the leaderboard is high, so the first aid of the brain trauma is very important. At present, the clinical treatment of head trauma mainly adopts a method of covering wounds by sterile dressing and then dressing by means of pressurization of an elastic headgear. Due to the abundance of blood vessels in the scalp, the subcutaneous tissue of the scalp is divided into many leaflets by fibrous trabeculae that connect the skin and the aponeurosis of the hat, where the vascular nerves of the scalp are located, which allows the blood vessels to be separated by dense, inelastic fibrous tissue. When blood vessels are broken due to trauma, the scalp can not contract automatically, so that much bleeding occurs, and meanwhile, the hair around the wound can influence the pressure of the elastic headgear on the wound. The existing elastic headgear adopts a face dressing type elastic pressing mode, so that aseptic dressing is loosened and slipped due to insufficient pressure, and then wound bleeding and infection are caused.

Disclosure of Invention

The invention aims to overcome the defects of the prior art, and provides a reasonable and practical adjustable headgear which has the advantages of convenience in use, firmness in fixation and good hemostatic effect, and can effectively ensure the purpose of firm pressure application and fixation on sterile dressings, so that the bleeding amount and infection rate of head wounds are effectively reduced.

In order to achieve the purpose, the invention adopts the following technical scheme:

an adjustable headgear comprises an elastic band horizontally arranged around the head via the forehead of a patient; elastic plates are fixedly connected to the belt body of the elastic bridle at the positions in front of and behind the ears of the patient, and the elastic plates vertically extend upwards along the outline of the head of the patient; the elastic board has one end fixed to the elastic belt as the fixed end, and the four elastic boards have suspended ends meeting in the wound and with elastic restoring force directed to the wound.

Preferably, the inner side surface of the belt body penetrating through the elastic bridle is convexly provided with a convex column, and the appearance of the elastic plate is in an L-shaped plate shape; the fixed end of the elastic plate is provided with a buckling hole, and a pin hole is formed between the convex column and the buckling hole for matching.

Preferably, the elastic plate positioned in front of the left ear of the patient is taken as a first elastic plate, the elastic plate positioned behind the left ear of the patient is taken as a second elastic plate, the elastic plate positioned in front of the right ear of the patient is taken as a third elastic plate, and the elastic plate positioned behind the right ear of the patient is taken as a fourth elastic plate; the knot hole on second elastic plate and the fourth elastic plate is multichannel and along the length direction equipartition in proper order of corresponding elastic plate stiff end place plate body.

Preferably, the elastic plate is provided with a paste layer on the surface of one side facing the head wound of the patient, the headgear also comprises an adhesive for adhering to the paste layer and increasing the pressure on the head wound of the patient, and the adhesive and the paste layer form a magic tape fixedly connected cooperation.

Preferably, a stabbing surface is arranged on the plate surface of one side, away from the wound of the head of the patient, of the suspension end of the elastic plate, and the sticking layer is composed of a hair surface; when the suspension ends of the four elastic plates are intersected at the wound of the head of a patient, magic tape type fixed connection matching is formed between the suspension ends of every two adjacent layers of elastic plates.

Preferably, a tension belt extends from the position of the convex column of the elastic bridle to the chin of the patient; the headgear also comprises a chin support which is wrapped at the chin of the patient, and the extending ends of the four tension belts are fixedly connected with the chin support.

The invention has the beneficial effects that:

1) the traditional elastic compression mode of the surface dressing type of the net-type elastic headgear is abandoned. The invention develops a new method, adopts four groups of independent elastic pressing block structures, takes an elastic belt as a bearing body, takes four elastic plates distributed in front of the left ear, behind the left ear, in front of the right ear and behind the right ear of a patient as pressure applying sources, and then realizes the point-to-point pressing effect of the head wound of the patient by mutually overlapping the suspension ends of the four elastic plates. Because the four elastic plates form a fixed-point compression phenomenon relative to the head wound of the patient, and the pressure between the elastic plates overlapped on each layer is higher than that of a single elastic plate, the purpose of firmly pressurizing and fixing the sterile dressing is further ensured, and the bleeding amount and the infection rate of the head wound are finally effectively reduced.

2) As a further preferred solution to the above, considering the difference of the head contour of the patient which may be caused in different age groups and even different body types, etc., even the difference of the position of the wound on the head of the patient may cause the need to select the elastic plate with the corresponding size. Therefore, the elastic plate which is in accordance with the shape of the head of the patient or can extend to the position of the head wound of the patient can be selected by self when needed through the matching of the buckle hole and the convex column, and the fixed end of the elastic plate is directly inserted into the position between the elastic belt and the skin of the patient; and then, the elastic plate is fixed by means of the buckling holes and the convex columns. At the moment, the back and forth movement of the elastic plate is limited by the elastic belt and the skin of the patient, and the left and right and up and down movements are limited by the positioning matching of the convex columns and the buckling holes, so that the elastic plate can reliably realize the purpose of elastically pressing the head wound of the patient. In addition, because the convex column is designed at the inner side of the elastic binding band, the height of the convex column should be smaller than the depth of the buckling hole at the elastic plate, so as to avoid uncomfortable feeling during use. Meanwhile, the buckling holes are designed on the elastic plate, the convex columns are designed at the elastic bridle, and when the buckling holes are plural, the elastic plate can still swing directionally around the axes of the convex columns, so that the elastic plate can be always pressed at the wound of the head of a patient accurately at a fixed point. Even considering the difference of the sizes of the brains of adults, the invention also arranges a plurality of buckle holes at the second elastic plate corresponding to the back of the left ear of the patient and the fourth elastic plate corresponding to the back of the right ear of the patient, thereby realizing the lifting adjustment function of the corresponding elastic plate along the elastic band while not influencing the swinging action of the elastic plates, and meeting the actual use requirement.

3) In order to improve the use comfort of the elastic plate and further improve the pressure application effect of the elastic plate relative to the head wound of the patient, the plate surface of one side, facing the head wound of the patient, of the elastic plate is provided with the adhesive layer, so that the adhesive fixing function of the relative adhesive is realized when needed. In fact, the suspension end of the elastic plate can be regarded as that the lower plate surface is provided with the sticking layer with the hair surface, and the upper plate surface is provided with the thorn surface, so that the sticking layer can not generate acupuncture feeling to the skin of a patient when the adhesive is not stuck on the sticking layer; meanwhile, when the suspension ends of the four elastic plates are overlapped with each other, the suspension ends of the four elastic plates can be prevented from sliding and staggering in the use process by means of magic tape type cooperation, and finally, the fixed-point force application effect of the suspension ends of the elastic plates relative to the head wound of a patient is effectively ensured.

4) On the basis of the structure, the tension belt structure is designed, and the chin rest positioned at the chin of the patient is matched, so that the lifting force generated by pressing the elastic plate on the wound can be partially or even completely counteracted by the downward tension of the tension belt when the tension belt is used, the situation that the elastic belt is separated from the head of the patient due to overlarge elasticity of the elastic plate is further avoided, and the use stability and reliability of the tension belt structure are finally ensured.

Detailed Description

For the purposes of understanding, the invention will be further described in its specific structure and mode of operation with reference to the accompanying drawings in which:

the invention is embodied in the form shown in fig. 1-4 and includes a resilient headband that fits around the head of a patient. The stretch headgear, in the embodiment shown in fig. 1-2, is implemented in the form of a stretch band 10. When needed, the elastic bridle 10 is horizontally encircled along the head of the patient, and the end parts of the elastic bridle 10 at the two end parts are fixedly connected by using magic tapes or other fixedly connected modes, so that the function of fixing the head of the patient relatively is realized.

On the basis of the structure, four convex columns 11 are arranged at the position of the belt body of the elastic bridle 10 corresponding to the front and back positions of the ears of a patient. In addition, the present invention is provided with an elastic plate 20 as shown in fig. 3 to 4. The elastic plate 20 is shaped like an "L" or "C" or other plate structure for facilitating the application of force. The fastening hole 21 is disposed at the fixed end of the elastic plate 20 to be inserted into the protruding pillar 11, so that the elastic plate 20 can be fastened to each other with respect to the elastic band 10. The fastening holes 21 are disposed at the fixed end of the elastic plate 20, so that when the pin holes are formed between the protruding columns 11 and the fastening holes 21, the fixed end of the elastic plate 20 is naturally clamped between the elastic band 10 and the skin of the head of the patient, thereby ensuring the fixing stability of the elastic plate 20 relative to the elastic band 10. An adhesive layer 22 formed by a relatively soft hair side b of a magic tape is arranged at the inner side plate surface of the elastic plate 20, and the force application effect of the elastic plate 20 relative to the head wound of the patient is improved through the cementation of the adhesive 30 relative to the adhesive layer 22.

The end use state of the present invention is shown in fig. 1. In practical use of the present invention, the elastic plate 20 with corresponding size is selected according to the contour size of the head of the patient. Firstly, the elastic band 10 is tied up and fixed on the head of the patient, then each elastic plate 20 is inserted between the elastic band 10 and the skin of the patient corresponding to the position of the elastic band, and then the fixed point fixing of the elastic plates 20 is realized by the convex columns 11 and the buckling holes 21. At this time, the front and back movement of the elastic plate 20 is limited by the elastic band 10 and the skin of the patient, and the left and right and up and down movements are limited by the positioning and matching of the buckle holes 21 and the convex columns 11, so that the elastic plate 20 can reliably realize the purpose of elastically pressing the head wound of the patient. If the downward pressure of the elastic plate 20 is further increased, the adhesive 30 made of medical soft glue can be adhered to the adhesive layer 22 of the elastic plate 20 at the bottom layer; if necessary, the adhesive 30 may be replaced by a medical article made of a flexible material such as a gauze roll. After the suspended ends of the elastic plates 20 are overlapped with each other, the mutual adhesion of the rough surface b and the stabbed surface a at the suspended ends of the elastic plates 20 in each layer as shown in fig. 2 to 4 can be utilized to further ensure the stable fit and the uniform force application of the suspended ends of the elastic plates 20. In addition, in order to improve the reliability of the present invention, as shown in fig. 1 and 2, a tension band 40 may extend to the chin of the patient at the matching point of each set of the buckle hole 21 and the convex pillar 11, and the four tension bands 40 may be joined to the chin rest 50, so as to ensure that the elastic band 10 does not fall off the head of the patient due to the elastic force of the elastic plate 20.
