Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, relates to acute epidural hematoma detection technology, and particularly relates to an epidural and subdural hematoma detection headgear. Background Art

[0002] In people's daily lives, there are some inevitable traumas, especially head injuries that pose a great threat to human life and health. Among them, epidural hematoma is one of the many threats. Epidural hematoma can occur at any age, especially in young and middle-aged people aged 15 - 50. Epidural hematoma is a hematoma that occurs between the inner table of the skull and the dura mater. Epidural hematoma accounts for 20 - 30% of traumatic intracranial hematomas; traumatic epidural hematoma often appears in a particularly acute or acute form, accounting for about 85%. Typical acute epidural hematoma is more common in young and middle-aged male patients with linear fractures, mostly in the frontotemporal and parietotemporal regions. Moreover, the temporal region contains the middle meningeal artery and vein, which are easily torn by fractures. Especially for rapidly developing epidural hematoma, the bleeding source is mostly caused by arterial injury. The hematoma increases rapidly and can cause brain hernia within a few hours, threatening the patient's life. Therefore, after a head injury, the need for detecting and monitoring epidural hematoma in patients is very urgent. One minute earlier detection allows the doctor to diagnose one minute earlier and take timely treatment actions, which is crucial for saving the patient's life. Being able to continuously, accurately and portably monitor epidural hematoma has become an urgent clinical need at present.

[0003] Currently, the existing methods for epidural hematoma detection generally include: ultrasonic exploration, skull X-ray film, cerebral angiography, CT scan, MRI scan, etc. Among them, the detection accuracy of CT is relatively high, but CT detection cannot achieve continuous detection and dynamic detection. In principle, surgical treatment should be carried out as soon as possible after diagnosis to achieve early diagnosis and timely treatment in order to effectively reduce the mortality rate. However, there are also many non-surgical treatments. Conservative treatment can be adopted for supratentorial acute epidural hematoma with clear consciousness, stable condition and hematoma volume less than 15 ml. But conservative treatment must dynamically observe the patient's consciousness, clinical symptoms and dynamic CT scan results. Once it is found that the hematoma increases, surgical treatment should be immediately changed. In this case, repeatedly transporting the patient will increase the patient's body movement, and if not careful, it will aggravate the patient's condition. Once encountering the peak period of CT scanning, there will also be a problem of queuing, bringing a lot of inconvenience to the patient's family. The cost of multiple CT scans cannot be underestimated, adding an invisible pressure to the patient's family.

[0004] Especially in the early stage of injury, patients will be sent to the hospital after being injured. During the period of being sent to the hospital, there is a great demand for epidural hematoma detection. The existing detection instruments include patch-type detection and pistol-type detection. This type of detection instrument has the following problems. First, the patch-type detection range is small and can only detect the hematoma at a few points. If you want to expand the detection range, you need to manually move the patch to change the detection position, and you may also need to move the patient's head. If you don't move the patient's head, you can't detect the patient's hematoma. Second, the patch-type is the same as the pistol-type. During the detection, it is affected by people's subjective consciousness. The location of the hematoma and the size of the hematoma are manually judged and predicted. Only the location where the hematoma is subjectively believed to be likely to occur can be detected. After arriving at the hospital, the doctor is not sure about the test results on the way, and will still ask the patient to take a CT scan. The detection before entering the hospital has not played a substantial role. Third, whether it is a patch or a pistol-type detection instrument, only a few points can be detected each time, and the data and signals of the detected points cannot be recorded. The doctor can only make subjective and rough judgments, and cannot restore the patient's actual hematoma situation with the detected data. Summary of the invention

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1 - 5 as shown, the specific embodiments provided by the present invention are as follows:

[0044] Embodiment 1:

[0045] An epidural and subdural hematoma detection headgear, characterized in that it includes

[0046] Detection components;

[0047] Wherein, the detection component includes a plurality of detection units, and the detection units are used to detect the thickness of the epidural hematoma at a local position of the patient's head;

[0048] Wherein, the detection component has an elastic material, and the elastic material is a headgear-like structure;

[0049] The elastic material has a front side and a back side, the front side is the side facing the patient's head, and the back side is the side away from the patient's head;

[0050] The front side has detection units and the back side has marking points.

[0051] At present, the mainstream methods for detecting epidural hematoma include CT detection, in addition to patch-type and pistol-type mobile detection devices. CT detection has a high accuracy rate, but the CT detector is large and heavy, and cannot be moved casually. Patients can only go to specific hospitals for CT detection. Due to the large size of the CT detector and other characteristics, some patients whose best option is to take CT to detect hematoma will take a greater risk of adopting suboptimal treatment due to conditions. Although patch-type and pistol-type mobile detection devices are easy to carry, their detection accuracy is limited, especially in remote areas far away from the hospital, where ambulances cannot reach the patient and the patient cannot walk. At this time, it takes a lot of time to find a feasible transfer tool. It takes a long time to transfer the patient to the ambulance and then to the hospital. The doctor has no way to judge the patient's specific situation on the way, wasting the best time to rescue the patient. Only after the CT test can a conclusion be made, and even if you arrive at the hospital, you cannot get treatment immediately. The treatment of epidural hematoma is very urgent, especially for rapidly developing epidural hematoma. The bleeding source is mostly caused by arterial damage. The hematoma grows rapidly and can cause brain herniation within a few hours, threatening the patient's life. If the patient needs to wait in line for a CT scan after being sent to the hospital, the probability of rescuing the patient is greatly reduced. Therefore, it is very necessary to provide a portable and highly accurate epidural hematoma detection device.

[0052] In this embodiment, if Figure 1The figure shows one of the implementation modes of the present scheme, which provides an epidural and subdural hematoma detection headgear 11, wherein the detection assembly includes a plurality of detection units, and the detection units are used to detect the thickness of the epidural hematoma at the local position of the patient's head; the elastic material is elastic and can be applied to patients with different head shapes. The side facing the patient's head has a detection unit for detecting the thickness of the hematoma in the skull at that position of the patient, and the side away from the patient's head has a marking point 12, which is used to observe the deformation of the headgear structure. Since the headgear-like structure will be stretched and deformed when worn on the patient's head, the position of the detection unit installed on the front side will also be displaced due to the stretching of the elastic material. The distance between two adjacent marking points will also change accordingly. The more the elastic material is stretched, the greater the distance between the two adjacent marking points. The change in the position of the detection unit can be reflected by the change in the distance between the two marking points.

[0053] Compared with CT detectors, the present invention is small in size and light in weight. It can be connected to a power source or have its own power source, meeting the conditions for non-hospital use. On the ambulance, the doctor can use a headgear for detecting epidural hematoma to perform preliminary tests on the patient. With the detection device, the patient's condition can be monitored and recorded in real time. The doctor on board can have a general understanding of the patient's condition and synchronize the information to the hospital. The hospital can prepare to receive the patient in advance to ensure that the patient can receive treatment immediately upon arrival at the hospital. After the patient is sent to the hospital, the expert doctor can refer to the patient's monitoring data to understand the patient's condition more quickly and take reasonable treatment actions before the condition worsens. This can largely buy precious treatment time to save the patient and reduce the probability of the patient's condition worsening to a certain extent.

[0054] Embodiment 2:

[0055] Detection of auxiliary components;

[0056] Wherein, the detection auxiliary component is a mesh structure, and the mesh structure is composed of a linear structure;

[0057] Wherein, the mesh structure is inelastic and bendable, and the mesh structure sags naturally due to gravity;

[0058] When the detection component is not subjected to external force, the mesh structure can fit with the reverse side of the elastic material;

[0059] Wherein, the intersection point of the linear structure and the linear structure is a compensation reference point;

[0060] Wherein, the compensation reference points coincide with the marking points in a one-to-one correspondence.

[0061] In the case of actual detection, due to the different head shapes and hair thicknesses of each patient, and the influence of substances such as head scars, ringworm, and dandruff, there are various situations in the skull outside the hematoma area of the patient, including relatively protruding skulls, relatively smooth skulls, and particularly, partially sunken skulls. Due to the differences in head shapes and sizes, for the same blood mass, different detection results will occur in the skulls of different patients. The following situations may occur: the hematoma volumes of two patients are the same, but different hematoma volumes are detected for the two patients; or the hematoma volumes of two patients are different, but the detection results are the same. Therefore, it is very necessary to consider the influence of head shape, etc. on the detection results. Since the size and shape of each patient's head are different, if the same headgear detection device is used to detect the epidural hematoma of the patient, the headgear-like structure has universality and is suitable for the head shapes of most patients. However, there will also be cases where the head shape exceeds the normal range. The different head shapes and sizes of patients will cause two adverse consequences. First, when the patient wears the headgear-like structure, the headgear-like structure does not fit well with the patient's head, and there is a gap between the headgear-like structure and the patient's head. At this time, the data detected by the detection unit is inaccurate. Second, when the head is particularly convex locally and the patient wears the headgear-like structure, the entire headgear-like structure is distorted, which has a great impact on the detection result.

[0062] In this embodiment, as Figures 2 - 3 shown in one of the implementation manners of this solution, the detection auxiliary member has a mesh structure 21, and the mesh structure is composed of linear structures; the intersection of the linear structures is the compensation reference point 22; the mesh structure has no elasticity and is bendable, and the mesh structure naturally sags due to gravity. Due to its own gravity, the mesh structure can press the bulging headgear-like structure against the scalp to achieve a state where the headgear-like structure fits well with the patient's head. When the headgear-like structure is not affected by external forces, the compensation reference points coincide with the marking points one by one. The compensation reference points represent the points in the standard coordinate system of the headgear-like structure. When the detection component is worn on the patient's head, the positions of the marking points change, and the compensation reference points and the coincident marking points have relative displacements. The head shape of the patient is fed back by calculating the displacement changes between the compensation reference points and the marking points. According to the shape of the patient's head in the detection area, the compensation coefficient in the detection area is obtained through a compensation algorithm; according to this compensation coefficient, the detection data after compensation in the detection area is obtained. The differences brought by head differences to the detection results can be reduced to a certain extent.

[0063] Example 3:

[0064] The marking point has a marking lamp;

[0065] Among them, the marking lamps present the same state at the same time.

[0066] In the actual use process of the headgear, with the frequent use of the headgear, the usage environment includes not only hospitals but also places such as ambulances where patients are in need. In many emergency situations, doctors do not have the condition to wear gloves for operations. A headgear can be used multiple times. The headgear is frequently picked up and put on the patient's head and taken off from the patient's head. When putting on the headgear for the patient, in order to ensure that it can be worn correctly at one time, there will be an action of estimating the position while holding the headgear by hand, and the contact time between the hand and the headgear is relatively long. The sweat on the hand, the blood of the patient, etc. cause the color of the marking point to fade or disappear. After being exposed to the air for a long time, many fine substances adhere to the marking point. When the patient wears the headgear, in most cases, the patient will lie flat and rest, and the patient's head contacts objects such as pillows. Due to the special shape of the pillow and the structure of the human head, the head of a severely ill patient will have a tendency to move, and a conscious patient will unconsciously move the head, causing friction between the marking point and objects such as pillows, and the color of the marking point is extremely easy to fade. In severe cases, the color of the marking point at the friction area is completely worn off.

[0067] In principle, the color of the marking point is different from the background color of the outer surface of the headgear. However, when the color of the marking point is wiped off, or the color of the adherent is very close to the background color, resulting in the position of the marking point not being detected, the head shape of the detected area of the patient will deviate, and the function of head shape compensation cannot be achieved. There are many sensors on the headgear, which are not easy to clean and are worn out after long-term use. If the marking point disappears, the compensation reference point loses the object for comparison, and the head shape of the detected area of the patient cannot be calculated.

[0068] In this embodiment, as Figure 4 shown in one of the implementation manners of this solution, Figure 3 for Figure 1 A in the figure, the marking point has a marking lamp 31. Compared with the marking color point, the marking lamp will not be wiped off due to long-term use, friction, etc., the marking lamp will not disappear, and the position of the marking point will not disappear. The marking lamps present the same state at the same moment, that is, the marking lamps light up and go out at the same time, and the lit colors are the same. When the position of the marking point is adhered by other fine substances and the marking lamp is partially blocked and the position of the marking point cannot be recognized, the lighting of the marking lamp can increase the recognition degree of the marking point. The present invention can effectively reduce the situation where the marking point disappears.

[0069] Embodiment 4:

[0070] The marking lamp is a patch lamp.

[0071] The marking lamp can emit light of a single color;

[0072] Among them, the marking lamp changes the emitting color at a certain time interval.

[0073] The marking lamp is located at the marking point. When the patient wears the headgear for monitoring, they are very likely to be in a lying position. The areas where the patient's head contacts substances such as pillows are also excluded from having the marking lamp. The marking lamp is prone to entanglement with substances such as pillows and is likely to press against the patient's head, causing discomfort to the patient. In severe cases, it will aggravate the patient's condition. After the marking lamp is blocked, for partially blocked marking lamps or those with a light-colored blocking object, increasing the recognition of the marking point can be achieved by making the marking lamp light up. However, for the situation where the marking lamp is completely blocked or the blocking object is dark in color, even if the marking lamp is lit, the position of the marking point cannot be restored.

[0074] In this embodiment, the marking lamp is a patch-type lamp, which is relatively thin and fits closely with the elastic substance. The patch-type marking lamp will not be entangled with substances such as pillows. On the other hand, it can also reduce the discomfort of the patient. By making the marking lamp emit light of a single color, the marking lamp changes the color of the emitted light at certain time intervals. The position of the marking point can be restored to a greater extent. One specific implementation method is as follows: A blue substance blocks the marking lamp, and the marking lamp emits blue light. The blue substance transmits the blue light and absorbs light of other colors, and the marking point appears blue, which can more prominently highlight the position of the marking point. In most cases, the substances blocking different marking points appear in different colors. In the present invention, by changing the color of the marking lamp, an image is recorded each time the marking lamp lights up a different color. Finally, based on all the obtained images, calculations and comparisons are made, and the position of the disappeared marking point is comprehensively obtained to achieve the effect of restoring the marking point.

[0075] Example 5:

[0076] The marking lamp can emit light of 9 colors.

[0077] The time interval is 1 s - 2 s.

[0078] As a preferred solution, the marking lamp can emit light of 9 colors, which can cover 90% of the disappeared marking points. The time interval for the marking lamp to change colors is 1 s - 2 s. The image acquisition module acquires one image within the interval period, and the position of the disappeared marking point can be restored.

[0079] Example 6:

[0080] The headgear-like structure is used to wrap the area to be detected on the patient's head;

[0081] Among them, the area to be detected does not include the eyes, nose, mouth, ears, and cheeks.

[0082] The detection unit includes a signal transmitter and a signal receiver;

[0083] Among them, there are multiple signal receivers around the signal transmitter;

[0084] Among them, the signal transmitter emits near-infrared light, and the signal receiver receives near-infrared light.

[0085] Generally, an epidural hematoma is commonly in the form of a blood clot, accompanied by a small amount of small blood clots. It is difficult to accurately detect the true situation of the blood clot using a single sensor or several sensors. If the blood clot in the patient is small, there is no need for surgery. However, due to limited detection equipment, misjudgment may lead to surgery for the patient, which will impose an additional burden on the patient and the patient's family. If the blood clot in the patient is large, if the size of the blood clot is not detected in time, it will pose a threat to life and health at any time if the surgery is not timely. The current focus of detecting epidural hematoma is on "detecting the thickness of the epidural hematoma", and it can only detect the conditions at several points, without detecting the "shape and area of the epidural hematoma".

[0086] In this embodiment, as Figure 5 shown in one of the implementation manners of the distribution of the detection units, the detection unit includes a signal transmitter 121 and a signal receiver 122; there are multiple signal receivers around the signal transmitter. The signal transmitter emits near-infrared light, and the signal receiver receives near-infrared light. Near-infrared light has strong penetration ability. Near-infrared light can penetrate tissues such as the skin and skull and form scattering in the brain tissue. The blood in the intracranial hematoma contains hemoglobin, and hemoglobin has specific absorption of near-infrared light. The thicker the hematoma, the more near-infrared light is absorbed by the hematoma, and the weaker the near-infrared light received by the near-infrared light receiver after refraction. Based on this principle, the thickness of the hematoma can be detected. There are multiple signal receivers around the signal transmitter of the present invention. By measuring the thickness of the hematoma at multiple points, compared with the patch-type hematoma detector, the detection range of the hematoma of the headgear of the present invention is wider. Finally, the specific shape and location area of the patient's hematoma are restored by combining the hematoma signals at multiple detection points.

[0087] Embodiment 7:

[0088] The detection units are evenly distributed;

[0089] Among them, when not under external force, the distance between the detection unit and its neighboring detection unit is equal;

[0090] Among them, the neighboring detection unit is the adjacent detection unit closest to the detection unit.

[0091] Among them, when not under external force, the distance between the detection unit and its adjacent detection unit is equal.

[0092] In this embodiment, when the headgear-like structure is not worn on the patient's head and is not subject to external forces, the detection units are evenly distributed, and the distance between a detection unit and its nearest adjacent detection unit is equal. Even when the headgear-like structure is worn on the patient's head and the distances between the evenly distributed detection units change, hematoma signals that are roughly evenly distributed can still be collected, providing feasible conditions for the calculation of signals in the later stage. The equal distance between the detection unit and the adjacent detection unit is one of the preferred solutions.

[0093] Embodiment 8:

[0094] The positions of the marking points correspond one-to-one with the positions of the detection units.

[0095] The change in the position of the marking points reflects the deformation of the elastic material, thereby reflecting the displacement of the detection units. It is impossible to infer from the change in the position of the marking points which specific detection units have undergone displacement. It can only reflect the general situation of the head shape in this area and cannot accurately calculate the result of the head shape.

[0096] In this embodiment, the positions of the marking points correspond one-to-one with the positions of the detection units, that is, each marking point represents the position of the corresponding detection unit, and the displacement of the detection unit can be specifically calculated through the displacement of the marking points.

[0097] Embodiment 9:

[0098] A compensation reference point and the corresponding marking point do not undergo relative displacement.

[0099] When the detection component is not worn on the patient's head and is not subject to external forces, the compensation reference point and the corresponding marking point coincide one-to-one. When the detection component is worn on the patient's head, the marking point undergoes a displacement change relative to the compensation reference point. The headgear-like structure is stretched when worn on the patient's head, and the mesh structure lies flat on the headgear-like structure due to gravity. Due to the different head shapes of the patients, the relative displacement between the compensation reference point and the marking point is very large, and the later calculation amount is very large.

[0100] In this embodiment, a compensation reference point and the corresponding marking point do not undergo relative displacement. By using a fixed point to limit the maximum relative displacement between the compensation reference point and the marking point, the calculation amount can be greatly reduced.
