Description

Novel mistaken-touch-preventing hand restraint device with monitoring and alarming functions and restraint system

Technical Field

The invention relates to the field of medical intelligent wearing equipment, in particular to a novel mistaken-touch-preventing hand restraint device with a monitoring and alarming function, which is mainly used for patients with vague consciousness or unconsciousness and severe cases with involuntary activities and critically ill patients.

Background

In the course of infectious disease treatment, it is necessary to isolate a large number of patients for treatment. Among them, critically ill or critically ill patients need intubation treatment to reduce mortality. Most patients undergoing intubation are in a state of confusion and most of the movements of their limbs are involuntary movements. Patients undergoing intubation treatment are prone to unconsciously or unconsciously touching the intubation equipment, which can easily result in the loss of intubation treatment and affect their life safety. In addition, in the department of critical care medicine, in order to effectively rescue lives, medical staff also need to wear a lot of protective equipment, on one hand, the medical staff cannot monitor the limb activities of critical patients in real time, and on the other hand, the medical staff has too many medical activities to handle in a ward, so how to effectively monitor the limb activities of critical patients or critically ill patients and effectively control the limb activities is a problem which needs to be solved by the department of critical care medicine.

For example, chinese patent publication No. CN110801329A discloses a novel anti-extubation hand restraint device with a monitoring alarm function. The hand restraint device comprises a glove body, a controller and an air pump, wherein the controller is installed in the air pump, a single chip microcomputer is arranged in the controller, a wrist part is arranged at the tail end of the glove body, a fixing belt buckle is arranged on the wrist part, main airbags are arranged in the palm position and the wrist part of the glove body, and inflation interfaces are installed on the glove body and the main airbags on the wrist part. This hand restraint device is through setting up the gasbag in the palm center position, detects patient's hand limbs motion amplitude by acceleration sensor, and when motion amplitude was too big, it aerifys to the gasbag in to open the air pump by single chip microcomputer control, the bloated gasbag to restriction patient's the crooked range of finger avoids the condition emergence that patient grabbed in disorder, plays the restriction effect to patient.

The device is suitable for patients who can get out of bed independently, and is used for preventing the patients from actively taking out of tubes due to psychological factors and the like. The device is used for limiting the movement of fingers and preventing a patient from actively gripping and extracting a tube by hands, and therefore, the device has the following defects: the patient may still touch the cannula even if the device is worn.

Furthermore, on the one hand, due to the differences in understanding to the person skilled in the art; on the other hand, since the inventor of the present invention has studied a lot of documents and patents when making the present invention, but the space is not limited to the details and contents listed in the detailed description, however, the present invention is by no means characterized in these prior art, but the present invention has been provided with all the features of the prior art, and the applicant reserves the right to increase the related prior art in the background art.

Disclosure of Invention

In the prior art, the hands and the like of a patient are fixed and restrained in a fixed mode in most cases. The patient can be restrained by binding the limb movement of the patient. However, this simple medical procedure involves patient dignity on the one hand and ulceration, pressure sores etc. at the patient's bindings on the other hand. In addition, the patient wearing the binding system is forced to maintain a specific posture for a long time, so that the comfort problem exists, and the patient is difficult to wear for a long time.

Aiming at the defects of the prior art, the invention provides a novel anti-false-touch hand restraint device with a monitoring and alarming function. The device includes: a palm restraint sleeve, an elbow restraint sleeve, a palm motion monitor, an elbow motion monitor and a data processor. A palm restraint worn on the patient's hand and wrist and primarily operable to restrict at least one dimension of motion of the patient's palm and wrist; an elbow restraint sleeve worn on the elbow of the hand of the patient and mainly used for placing the arms (big arm and small arm) of the patient in a comfortable state or a state beneficial to the rehabilitation of the patient; the palm part motion monitor is arranged on the palm part restraining sleeve and is used for monitoring the motion of the palm part and the wrist part of the patient so as to acquire a palm part motion parameter and a wrist part motion parameter; the elbow motion monitor is arranged on the elbow restraint sleeve and used for monitoring the motion of the large arm and the small arm of the patient and acquiring motion parameters of the large arm and the small arm; and the data processor is respectively in data connection with the palm motion monitor and the elbow motion monitor. The palm motion monitor and the elbow motion monitor can be a micro acceleration sensor, an angle sensor, a displacement sensor and the like, and the data processor can calculate the motion posture of the patient by utilizing the collected parameters.

In the actual medical practice process, the contact type medical instruments such as a cannula are touched by the hand of a patient, which is a small probability event that cannot be controlled. Firstly, most patients adopt lying positions, most of which are in a natural relaxed state (especially patients with fuzzy consciousness or unconscious patients), and the arms are attached to a sickbed; secondly, the patient's hand touches the cannula and certain conditions need to be met, namely: firstly, the large arm and the small arm are lifted and have certain postures, and secondly, the hand and the wrist also need certain postures to reach the condition of touching the cannula.

Therefore, the false-touch-prevention hand restraint device provided by the invention is not a real fixed restraint device but a movable restraint device. The purpose of the restraint device is: for unconscious or unconscious patients, it is possible to allow the hands of the patient to move unconsciously, but this movement is not possible to touch any contact medical device (such as a cannula) arranged on his body part. Such benefits are mainly: 1. the patient can be recovered by allowing the involuntary movement, and doctors can clearly know the involuntary movement condition of the patient through data curve data fed back by the data processor, so that the doctors can know vital signs of the patient; 2. respect of the patient: some critically ill patients also indicate that their life is about to end when undergoing treatment such as intubation, and by allowing their exercise to preserve the dignity of their life time, the patient is given psychological comfort, and their life may be extended or their patient's condition may be improved; 3. the movement of the limb may rarely cause the patient to touch the contact medical instrument, and therefore it is completely unnecessary not to allow the patient to move his hand, i.e.: it is not necessary to acquire motion data at all times. Therefore, the invention further provides the following technical scheme: under the condition that the activity postures corresponding to the upper arm motion parameters and the lower arm motion parameters trigger early warning conditions, the palm motion monitor collects the palm motion parameters and the wrist motion parameters under the condition that the palm constraint sleeve does not limit the activities of the hand and the wrist; wherein, in the event that an active pose corresponding to the palm and wrist motion parameters triggers an adjustment condition, an adjustment component in the palm and/or elbow cuffs is activated in a manner that limits at least one dimension of motion of the patient's hand and wrist in response to the data processor adjustment signal to prevent the patient from touching the medical contact instrument. Namely: aiming at unconscious or vague consciousness patients, the hands are limited when the hands move to dangerous postures in the state of early warning posture, and the medical instruments such as cannula and the like are prevented from being touched.

According to a preferred embodiment, the elbow restraint sleeve is capable of returning to the normal state in such a way that the elbow entrains the palm portion in such a way as to limit the palm portion from entering a forbidden area if the active position of the palm portion triggers the adjustment condition.

According to a preferred embodiment, the hand restraints are responsive to the adjustment signal before the elbow restraints do not initiate an elbow pose adjustment for limiting at least one dimension of motion of the palm and/or wrist to urgently avoid a contact instrument. Since the patient's involuntary movements may be too violent and disorderly, in these disorderly tasks, the palm or wrist may not have touched the adjustment condition at the previous moment, but may touch the contact device at the next moment, and the elbow restraint sleeve may not have reached the adjustment of the movement posture of the arm, it is necessary to avoid the medical contact device urgently by means of the palm restraint sleeve.

According to a preferred embodiment, the elbow restraint sleeve includes a support bladder plate extendable from a body thereof to the wrist, the support bladder plate being configured to: the support cell plate, when inflated, can gradually restore the small arm to be substantially in line with the large arm; the support cell plate is capable of bending when it is not inflated to allow free movement of the elbow.

According to a preferred embodiment, the data processor is capable of activating a video monitor based on the palm motion parameter and the increment of the wrist motion parameter monitored by the palm motion monitor, so that the restraint device is capable of activating the abnormal posture determination mode by means of the video monitor.

According to a preferred embodiment, the palm and elbow restraints are provided with a reset force sensor, the reset force sensor detecting a reset force when the palm and elbow restraints restrict at least one movement dimension of a hand, the data processor being able to adjust the reset rate of the adjustment elements of the palm and elbow restraints on the basis of the reset force.

According to a preferred embodiment, the palm motion monitor, the elbow motion monitor and the reset force sensor are all wirelessly connected to the data processor.

According to a preferred embodiment, the data processor is communicatively connected to an alarm terminal in response to the adjustment signal, the alarm terminal being capable of being presented with at least one prompt of sound, light, text, pictures, images with the hand restraint sleeve limiting at least one dimension of motion of the patient's hand and wrist.

In accordance with a preferred embodiment, the present invention discloses a hand restraint system comprising: a palm motion monitor disposed in the palm restraint sleeve for monitoring the movements of the palm and the wrist of the patient to obtain palm motion parameters and wrist motion parameters, an elbow motion monitor disposed in the elbow restraint sleeve for monitoring the movements of the large arm and the small arm of the patient to obtain large arm motion parameters and small arm motion parameters, and a data processor respectively in data connection with the palm motion monitor and the elbow motion monitor for acquiring the hand motion parameters and the wrist motion parameters under the condition that the motion postures corresponding to the large arm motion parameters and the small arm motion parameters trigger early warning conditions; wherein, in the event that an activity gesture trigger adjustment condition corresponding to the palm motion parameter and the wrist motion parameter, an adjustment component of the palm restraint sleeve and the elbow motion monitor is activated in response to an adjustment signal of the data processor in a manner that limits at least one motion dimension of the patient's hand to prevent the patient from touching the medical contact instrument.

Detailed Description

This is described in detail below with reference to fig. 1-4.

Example 1

The embodiment discloses a novel prevent mistake and touch hand restraint device of area monitoring alarming function. The hand restraint device is particularly a restraint device that limits the range of motion of the hands of unconscious or unconscious patients. The restraint device includes a palm restraint sleeve 100, an elbow restraint sleeve 200, a palm motion monitor 300, and an elbow motion monitor 400.

A palm restraint cover 100 worn on the palm and the wrist of the patient for limiting the range of motion of the palm and the wrist.

And an elbow restraint cover 200 which is worn on the elbow of the hand of the patient and can restore the upper arm and the lower arm to normal postures.

A palm motion monitor 300 disposed in the hand restraint 100 for monitoring the patient's hand and wrist motion to obtain palm and wrist motion parameters. Palm motion monitor 300 may be at least one of an acceleration sensor, a displacement sensor, and an angle sensor.

An elbow motion monitor 400, disposed in the elbow restraint sleeve 200, for monitoring the motion of the patient's upper and lower arms, acquiring upper arm motion parameters and lower arm motion parameters. The elbow motion monitor 400 may be at least one of an acceleration sensor, a displacement sensor, and an angle sensor.

And a data processor 500 in data communication with palm motion monitor 300 and elbow motion monitor 400, respectively. The data processor 500 may include a server having a data operation function, such as a CPU, a GPU, and an FPGA.

According to clinical observation, the patient needs to touch the cannula at least to complete the following actions: the arm is flexed and the palm is in a particular position. Thus, based on clinical observations and data studies, the present invention can allow the patient's hand to move at a non-specific location, while responding to monitoring as the hand enters a specific location, so that the patient's hand can move out of the specific location. This way, the occurrence of pressure sores and ulcerations on the patient can be effectively reduced, and the patient can be treated with the device with a high degree of dignity.

Firstly, the cavity conditions of the patient to touch the cannula are: the big arm and the small arm have certain moving postures. Namely: the moving postures of the big arm and the small arm need to trigger an early warning condition. The early warning condition can be related to different positions of the medical contact-type instrument, the arm length of the arm of the patient, the arm lengths of the big arm and the small arm and the like. For example, the medical contact apparatus may include: trachea, stomach tube, urinary catheter, and the like. The doctor inputs the arm length, the large arm, the small arm length, the cannula position, the cannula external length and other parameters of the patient into the data processor 500, and the data processor 500 pre-generates the spatial attitude range of the early warning condition. The generated model of the early warning condition can be generated after deep learning based on a plurality of clinical data. The pre-alarm condition may also be pre-defined by the physician. The early warning condition is a spatial attitude range, and the early warning condition is triggered as long as the activity attitude of the patient falls within the spatial attitude range. Further, when the moving posture of the forearm and the forearm triggers the warning condition, the patient does not necessarily touch the medical touch instrument, and at this time, the probability that the patient only touches the medical touch instrument is increased, and therefore, it is necessary to monitor the movements of the palm and the wrist. To this end, the data processor 500 is configured to: under the condition that the activity postures corresponding to the motion parameters of the large arm and the small arm trigger the early warning condition, the collected signals are sent to the palm motion monitor 300 to collect the motion parameters of the hand and the motion parameters of the wrist, and at the moment, the palm restraint sleeve 100 does not limit the motion of the palm and the wrist. Namely: in the case where the active pose corresponding to the palm motion parameters and wrist motion parameters triggers an adjustment condition, the adjustment components of palm cuff 100 and/or elbow cuff 200 are activated in response to an adjustment signal from data processor 500 in a manner that limits at least one dimension of motion of the hand to prevent the patient from touching the medical contact instrument. The adjustment condition is also preset, which falls within a narrower range of the activity space within the early warning condition. For example, the adjustment condition may be that the palm is 5 cm from the cannula. And the early warning condition is that the straight line distance between the palm and the intubation tube is 15 centimeters. The at least one motion dimension by constraint hand may be: limiting the continued linear motion of the palm adjacent the cannula or limiting the angle at which the wrist continues to deflect toward the cannula, etc.

Preferably, hand cuff 100 is responsive to an adjustment signal for limiting at least one dimension of motion of the palm and/or wrist to evade the contact instrument before elbow cuff 200 does not initiate an elbow pose adjustment. The adjustment signal of the data processor 500 is a signal for preventing the hand, particularly the palm, from touching or grasping the cannula. Due to the physiological structure and physiological reaction of the human body, the probability of touching or grabbing the cannula is higher in the palm part compared with the arm, so that the emergency restraint on the hand is particularly important. For example, when the patient's limb movement is strongly responsive, especially in the spatial range corresponding to the arm entering the pre-alarm condition, the data processor 500 may extract strong characteristic values, such as acceleration, displacement amplitude, etc., based on the hand motion parameters and wrist motion parameters collected by the palm motion monitor, to determine whether to limit at least one motion dimension of the palm and/or wrist to avoid the contact apparatus urgently. Based on the concept of space, the motion dimension is three-dimensional with 6 degrees of freedom, i.e. the palm and/or wrist can be prevented from moving linearly, rotating, etc.

Preferably, the elbow restraint sleeve 200 includes a support bladder plate 900 that can extend from its body 200e to the wrist. The body 200e is also configured to be inflatable. The support panel 900 is configured as an inflatable panel. Which is worn semi-open on the forearm of the patient. The support cell plate 900 is configured to: the support panel 900, when inflated, is capable of gradually returning the small arms to be substantially in line with the large arms. The support panel 900 is capable of bending in its uninflated condition to allow free motion of the elbow. So that the elbow can move within a range of motion with the small arm relative to the large arm based on the amount of inflation of the support panel 900. On the contrary, the elbow restraining sleeve 200 can be restored to the normal state in such a manner that the elbow carries the palm portion while the support bladder 900 is gradually inflated, in such a manner that the palm portion is restricted from entering the inhibited area. Preferably, the support bladder plate 900 and the body 200e start to be automatically inflated based on the external inflator in the case where the active posture of the palm portion triggers the adjustment condition. Preferably, the elbow cuff 200 is triggered when the palm or motion of the patient is not intense but stays in a spatial range corresponding to the adjustment condition for a long time, as compared to the adjustment condition of the hand cuff 100, for gradually restoring the patient's hand to a normal state based on the elbow cuff 200.

Preferably, data processor 500 is capable of activating video monitor 700 based on the increment of the palm motion parameter and the wrist motion parameter monitored by palm motion monitor 300. Video monitor 700 is an auxiliary monitoring device. The increments of the palm and wrist motion parameters characterize the movement intensity of the palm and wrist. When the video monitor 700 is activated, the medical staff can determine the abnormal posture of the patient based on the image data, which is particularly important for the prevention and control of infectious diseases. Because in the infectious disease ward, the work that medical personnel need go on is complicated and dress protective apparatus, can't monitor patient's limbs action constantly or the person can't clearly, and then can't carry out the record to patient's condition. And the unconscious action of the patient happens in the carelessness, so the monitoring is needed by the video monitor 700, the video signal of the video monitor 700 is forwarded to the prevention and control terminal by the data processor 500, the medical staff at the terminal carries out the remote monitoring, and the terminal is convenient for the medical staff to carry out the adjustment of the treatment scheme on the patient.

Preferably, both the palm restraint sleeve 100 and the elbow restraint sleeve 200 are provided with a reset force sensor 800. The reset force sensor 800 collects reset forces with the palm and

elbow restraints sleeves

100, 200 restricting at least one dimension of motion of the hand. The data processor 500 is capable of adjusting the rate of repositioning of the adjustment elements of the palm restraint sleeve 100 and the elbow restraint sleeve 200 based on the repositioning force. That is, when the hand of the patient is restored, the data processor 500 may adjust the execution rate of the adjustment elements of the palm and elbow constraining

sleeves

100 and 200 by the restoring force, enhancing the comfort of the patient.

Preferably, palm motion monitor 300, elbow motion monitor 400 and reset force sensor 800 are all wirelessly connected to data processor 500. Preferably, the data processor 500 is not disposed in the elbow restraint sleeve 200 and the palm restraint sleeve 100, and the data processor 500 may be disposed inside the ICU ward, and may be wirelessly connected with the sensor devices such as the palm motion monitor 300, the elbow motion monitor 400 and the reset force sensor 800 through bluetooth, EnOcean, etc. protocols. Thus, the patient, after wearing elbow restraint sleeve 200 and palm restraint sleeve 100, visually sees a "cordless" restraint, giving the patient a dignity in performing the treatment. Preferably, the elbow motion monitor 400 has at least two, at least one at the upper end of the elbow restraint sleeve 200 (corresponding to the patient's forearm) and at least one at the lower end of the elbow restraint sleeve 200 (corresponding to the patient's forearm), respectively. Preferably, the palm motion monitor 300 is provided with at least one motion parameter of the palm motion monitor 300, which indirectly reflects the motion of the wrist with the parameters collected by the elbow motion monitor 400 corresponding to the forearm of the patient.

Preferably, the data processor 500 is communicatively coupled to the alarm terminal 600 in response to the adjustment signal. The alarm terminal 600 can be presented in at least one of sound, light, text, picture and image under the condition that the hand restriction sleeve 100 restricts at least one motion dimension of the palm and wrist of the patient. That is, when the palm and the wrist of the patient move violently, the alarm terminal 600 can record the limiting condition of the hand and the wrist under the constraint condition of the hand constraint sleeve 100 through sound, light, characters, pictures and images, and can prompt the medical staff that the patient cares the patient to obtain effective nursing through the unconscious action.

Example 2

This embodiment may be a further improvement and/or a supplement to embodiment 1, and repeated contents are not described again. The preferred embodiments of the present invention are described in whole and/or in part in the context of other embodiments, which can supplement the present embodiment, without resulting in conflict or inconsistency.

The present embodiment provides a restraining device that prevents dangerous movement of an unintended hand. As shown in fig. 2 or 3, the restraining device includes an elbow restraining sleeve 200 and a palm restraining sleeve 100. The elbow restraint sleeve 200 is worn on the elbow of the patient's hand. The palm restraint sleeve 100 is placed inside the palm of the patient's hand and is generally spherical or ellipsoidal, i.e., the palm of the hand. In the present invention, the elbow restraint cover 200 is provided with the first airbag 200 a. The first airbag 200a is filled with gas in advance. The first air bag 200a is in communication with the air tube 200b disposed at the elbow cuff 200. The trachea 200b also communicates with the volar ball 100. The volar ball 100 is an inflatable ball. In a preferred embodiment of the present invention, the restraining device comprises: the elbow restraint sleeve 200 is worn on the elbow region of the patient with the palm of the patient's hand holding the volar ball. When the big arm and the small arm of the patient are bent, the air bag is compressed, the palm ball expands, the fingers of the patient are unfolded by the palm ball, the finger joints cannot be folded, the finger joints are restrained, and therefore the fingers of the patient cannot be pulled out; secondly, because the gas is injected into the first air bag 200a, the first air bag 200a has reaction force when the large arm and the small arm bend, and can counteract the acting force generated when the large arm and the small arm bend, because the arm of the unconscious patient bends unconsciously, the generated acting force is not too large generally, the air bag has the function of slowing down the bending tendency of the large arm and the small arm, and can effectively buffer the unconscious action of the patient. For a patient intubated with a trachea, the patient has at least the following actions to perform an unconscious act of drawing a tube: the large arm and the small arm need to be bent to a certain degree, and the finger joints are free from constraint. When the big arm and the small arm of the patient bend, the first air bag 200a is compressed to inflate the palm restraint sleeve 100, the knuckle is expanded by the palm ball based on the inflation of the first air bag 200a, so that the knuckle is restrained by the palm ball, and the patient cannot finish the extubation action.

The first bladder 200a is preferably located between the upper and lower arms when the cuff is worn on the elbow, as shown in FIG. 1, the first bladder 200a is located in a central position of the elbow restraint 200. when worn, the elbow restraint 200 is worn partially on the lower arm and partially on the upper arm, with the axis of the first bladder 200a generally perpendicular to the axis L between the upper and lower arms. that is, the first bladder 200a is worn about the elbow joint in a manner that is axially disposed more or less along the circumferential direction of the elbow joint. the first bladder 200a is capable of injecting gas into the palm restraint 100 based on the pressure created when the upper and lower arms are angled.

Preferably, the elbow restraining sleeve 200 includes an outer sleeve 200c and an inner sleeve 200 d. The outer liner 200c and the inner liner 200d are fixedly coupled to each other. For example, the outer liner 200c and the inner liner 200d may be bonded or sewn. The inner liner 200d requires skin fit of the patient and may be supported by, for example, a cotton cloth material.

Preferably, the inner liner 200d has a through hole (not shown) for fitting the first balloon 200 a. The first bladder 200a is closely attached to the inner side of the outer liner 200c through the through hole. For example, the first bladder 200a may be bonded to the inside of the outer liner 200c to be disposed inside the elbow restraint cover 200.

Preferably, outer liner 200c includes air cap 200 c-1. The outer liner 200c has a sleeve cavity (not shown) into which gas can be injected so that the elbow restraint sleeve 200 is not easily bent, and thus, the large and small arms of the patient are not easily bent. For example, during medical procedures in which the patient is more involuntary, the physician may inject gas into the outer liner 200c so that the patient's upper and lower arms are less likely to bend. Alternatively, during a medical treatment in which the patient has less involuntary movements, the physician may expel the gas injected inside the outer liner 200c while allowing the patient's big and small arms to have some flexion movement, while restraining the fingers by cushioning the flexion movement of the big and small arms and injecting the gas into the volar ball by the first bladder 200a between the big and small arms.

Preferably, the palm restraint sleeve 100 is removably connected to the air tube 200 b. For example, the palm restraint sleeve 100 and the air tube 200b are connected by a screw thread. The palm restraint sleeve 100 has a mouth hole 100 d. The mouth hole 100d is in communication with the air tube 200 b. When the patient's arm and forearm bend, the first bladder 200a is compressed and inflated to assume an inflated condition. When the arms and the lower arms of the patient are unfolded, the gas in the palm restraint sleeve 100 is discharged back to the first air bag 200a for storage.

Preferably, the air tube 200b is a bellows tube. Which may be adjusted based on the length of the patient's lower arm.

Preferably, palm restraint 100 is provided with at least two finger holes 100c to enable palm restraint 100 to be worn on the palm of the hand. The finger hole 100c is sewn to the volar ball. Preferably, there are three finger holes 100c for restraining the thumb, middle finger and little finger, respectively.

Preferably, palm restraint sleeve 100 includes inflatable chambers 100 a. The flexible shell 100b comprises an outer surface layer, a latex layer, a rubber layer and a memory sponge layer from the outside layer in sequence. The ground meat shell 200a is rotated to form the cavity 200 b.

Preferably, the elbow restraint sleeve 200 is connected to the palm restraint sleeve 100 by a support bladder plate 900. The support cell plate 900 is made of elastic cotton. The support panel 900 may be adapted to fit against the lower arm of the patient on the one hand and to position the trachea 200b on the other hand. Preferably, the air tube 200b may be adhered to the support pocket plate 900. Alternatively, the support bladder plate 900 may be provided with a dedicated passage through which the air tube 200b communicates with the first air bladder 200a and the palm restraint sleeve 100, respectively.

Preferably, as shown in fig. 2, the elbow restraint sleeve 200 is side-open. Namely: the elbow restraint sleeve 200 has a wearing-side opening 200f for wearing from the arm side. Then, a magic tape was used for adhesion, and the cuff was fastened to the arm with a restraint band 200 g. Since the unconscious patient cannot speak, the medical staff cannot easily grasp whether the first air cell 200a is aligned with the elbow joint by adopting the conventional wearing mode from both ends of the cuff. With this side-open wearing, the medical staff can first align the first bladder 200a with the inner side of the elbow joint and then fix the cuff to the arm of the patient.

under the condition that the activity postures corresponding to the large arm motion parameters and the small arm motion parameters trigger early warning conditions, the palm motion monitor 300 collects the hand motion parameters and the wrist motion parameters under the condition that the palm constraint sleeve 100 does not limit the activities of the hand and the wrist;

wherein in the event that the active pose corresponding to the palm motion parameter and the wrist motion parameter triggers an adjustment condition, the adjustment components in the palm restraint sleeve 100 and the elbow motion monitor 400 are activated in a manner that limits at least one dimension of motion of the patient's hand in response to the adjustment signal from the data processor 500 to prevent the patient from touching the medical contact instrument.

Preferably, the data processor 500 is communicatively coupled to the alarm terminal 600 in response to the adjustment signal, the alarm terminal 600 capable of being presented in the form of at least one of sound, light, text, pictures, images with the hand restraint sleeve 100 restricting at least one dimension of motion of the patient's hand and wrist.

Preferably, palm motion monitor 300 is integrated into palm restraint 100, thereby constituting a palm control. The elbow motion monitor 400 is integrated with the elbow restraint sleeve 200 to constitute an elbow control. The data processor 500 establishes data connections with the palm control and the elbow control, respectively, in a wireless connection. The palm control and the elbow control are capable of establishing a powered connection in data interaction with each other such that both adjustment components are capable of limiting at least two motion dimensions of the patient's hand in response to adjustment signals from the data processor in the event that an activity gesture corresponding to the palm motion parameter and the wrist motion parameter triggers an adjustment condition. That is, the palm control portion and the elbow control portion can be interlocked with each other, preventing the patient from touching the contact type medical instrument simultaneously in at least two degrees of freedom. The simultaneous adjustment of the palm control and the elbow control in two or more motion dimensions poses a risk of injuring the patient, so that the mutual linkage of the palm control and the elbow control has overload protection (i.e. if the resultant force between the two limits exceeds a certain magnitude), the hand restraint system of the present invention will give a reset command to terminate the adjustment motion regardless of the command signal of the data processor 500, and alarm through the alarm terminal 600. The adjustment movements in at least two motion dimensions constitute a preferred embodiment of the invention, which is suitable for situations in which the patient is dependent on the device for survival (for example, on the ventilator or dialysis machine for survival), wherein a false touch on the touch-sensitive control panel can itself lead to serious life-threatening consequences. The linkage of the palm control and the elbow control can be in a step-by-step manner, and the data processor 500 can predetermine the resultant force generated by the step-by-step movements of the two and reset and give an alarm if a certain threshold is exceeded. The adjustment movement in at least two movement dimensions constitutes a preferred solution according to the invention, also because it is also suitable for pediatric patients, while at the same time preventing access to the medical contact instrument in a more drastic manner, and at the same time ensuring a moderate freedom of movement of the patient. Clinical trials have shown that children do not have significant wearing refusal, i.e., giving the patient the appropriate freedom of motion has, in turn, a significantly safer motion limiting effect.

The adjustment action in only one motion dimension is the preferred solution of the present invention because the computational analysis workload of the data processor 500 is minimized and an optimal solution between cost and security is found. However, when data processor 500, in data communication with palm motion monitor 300 and elbow motion monitor 400, determines from the motion analysis that a single motion dimension is insufficient to prevent dangerous motion of the patient touching the medical contact instrument, data processor 500 intermittently sequentially and/or alternately activates the adjustment motions of the palm control and elbow control (and/or sequentially and/or alternately activates the adjustment components of palm restraint sleeve 100 and elbow motion monitor 400). During the adjustment movement, the intermittently successive and/or alternately initiated adjustment movements are preferably carried out in a stepwise manner and preferably in one direction of movement (movement dimension). During the execution of the adjustment movement in one direction of movement (movement dimension), the data processor 500 adjusts the magnitude of the stepping movement in a single direction of movement according to the acceleration of the dangerous movement (the movement executed when the patient touches the medical contact instrument), while the analysis determines whether the next movement should be executed by the palm control or the elbow control. "alternate" means that the palm control and the elbow control intervene alternately with each other, performing movements in different movement directions, respectively. And "in turn" means that one of the palm control and the elbow control performs several stepwise movements in time succession, "in turn" especially performs a plurality of movements in one direction. The reason for the above control is that, on one hand, the inventor of the present invention recognizes that the bedridden person has fragile bones and is prone to fracture, and on the other hand, the safety of the equipment should be regarded as human-oriented, so the safety of the person is considered to be a priority. By the control method, the injury to the patient in the bed can be avoided on the premise of ensuring the reliable operation of the medical contact instrument to the maximum extent.

It should be understood by those skilled in the art that the present specification and drawings are illustrative only and are not limiting upon the claims. The scope of the invention is defined by the claims and their equivalents.
