[0034] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0035] like Figure 1 , Figure 2 and Figure 6 As shown, an intelligent arm restraint in one embodiment of the present invention comprises a first protective cover 1 and a second protective cover 2, and a zipper 3 is installed on both the first protective cover 1 and the second protective cover 2. The zipper 3 is arranged at the front end of the first protective cover 1 and the second protective cover 2, and the front end of the first protective cover 1 and the second protective cover 2 can be separated and combined through the zipper 3. The intelligent arm restraint also includes a tightening mechanism and a control mechanism.

[0036] like Figures 2 to 8 As shown, the intelligent arm restraint also includes an operation box 4, which is fixedly mounted on the first protective cover 1 and the second protective cover 2, and the tightening mechanism and the control mechanism are both mounted in the operation box 4. The operation box 4 is provided with an operation panel 48 for controlling the tightening mechanism and the control mechanism, and a battery 45 for powering the tightening mechanism and the control mechanism is also installed in the operation box 4.

[0037] The tightening mechanism is used to fix the patient's forearm, and the tightening mechanism includes an annular airbag 5, which is bonded to the first protective sleeve 1 and the second protective sleeve 2. The tightening mechanism also includes an air supply component matched with the annular airbag 5, and the air supply component is used to realize the inflation and deflation of the annular airbag 5.

[0038] The control mechanism includes a first intelligent module 41 and a second intelligent module 42. The first intelligent module 41 is connected to the air supply component. The second intelligent module 42 is used to collect the movement trajectory of the patient's arm. The second intelligent module 42 can determine the distance between the patient's arm and the treatment pipeline when the patient's arm moves. The second intelligent module 42 is also provided with a monitoring component, which is connected to the second intelligent module 42. The second intelligent module 42 is connected to the nurse station via a wireless signal.

[0039] The air supply assembly includes a first air pump 43, on which a plurality of air pressure valves 44 are installed. The first air pump 43 is connected to the annular airbag 5, and a gas source controller 411 for controlling the plurality of air pressure valves 44 is installed on the first intelligent module 41. Specifically, the patient's hand is passed through the annular airbag 5, so that the patient's palm is placed in the first protective sleeve 1 and the second protective sleeve 2, and then the first air pump 43 is started. The first air pump 43 inflates the annular airbag 5, and the annular airbag 5 can wrap the patient's forearm after swelling, preventing the patient's hand from being pulled out of the first protective sleeve 1 and the second protective sleeve 2. At this time, the patient's hand can move in the first protective sleeve 1 and the second protective sleeve 2, preventing the patient's hand from being immobile for a long time. The muscle soreness caused by the patient's hand being immobile for a long time increases the comfort of the patient's hand and prevents the patient from being irritable.

[0040] When the annular airbag 5 is wrapped around the patient's forearm, the air pressure valve 44 can detect the pressure between the annular airbag 5 and the patient's forearm, preventing the annular airbag 5 from being too tight and causing blood flow problems in the patient's forearm. Specifically, when the annular airbag 5 is wrapped around the patient's forearm, it first strangles the patient's forearm. After the pressure signal is transmitted to the air source controller 411 by the air pressure valve 44, the first intelligent module 41 performs data verification, identifies the patient's forearm dimensions, and controls the air pressure valve 44 to deflate the annular airbag 5, so that the air pressure in the annular airbag 5 is reduced. The ring part of the annular airbag 5 is slightly larger than the patient's arm dimensions, which can prevent the patient's palm from being pulled out of the first protective sleeve 1 and the second protective sleeve 2, and will not cause pressure on the patient's forearm, thereby ensuring the patient's comfort when wearing it and preventing the patient from becoming anxious due to discomfort.

[0041] Furthermore, the tightening mechanism also includes a reel 49, which is installed in the operating box 4, and a rotary motor 491 is installed on the reel 49. A second locking belt 492 is wound on the reel 49, and one end of the second locking belt 492 away from the reel 49 passes through a side wall of the operating box 4. The rotary motor 491 is matched with the second intelligent module 42, and the rotary motor 491 receives the instruction of the second intelligent module 42 to rotate.

[0042] Specifically, if a treatment tube is inserted into the patient's body, the patient may unplug the treatment tube unconsciously due to itching, pain or foreign body sensation. At this time, the end of the second locking belt 492 away from the reel 49 is tied to the bed, so that the operation box 4 is fixed on the bed close to the second locking belt 492, and then the straight-line distance between the patient's hand and the treatment tube on the patient's body is input into the second intelligent module 42 through the operation panel 48. After calculation by the second intelligent module 42, the length of the second locking belt 492 released from the reel 49 can be obtained. The patient's arm can move within the range where it cannot touch the treatment tube, preventing the patient's arm from being fixed and unable to perform any movement, resulting in soreness, numbness, etc. in the patient's arm, thereby causing the patient to be irritable and unwilling to be treated, affecting the patient's treatment effect.

[0043] At the same time, a motion sensor is provided on the monitoring component. If a patient has mental problems and wants to break free from the intelligent arm restraint, the patient will not only pull the second locking belt 492 hard, but also swing his arm greatly. The rotary motor 491 senses a relatively large pulling force, and after judging that the patient is out of control by combining the motion sensor and the patient's arm movement information collected by the second intelligent module 42, the rotary motor 491 starts, rotates the reel 49, shrinks the second locking belt 492, and makes the operation box 4 gradually approach the connection between the second locking belt 492 and the bed, until the patient's arm is fixed on the bed. When the patient no longer struggles violently and the body is calm, the rotary motor 491 rotates in the opposite direction to release the second locking belt 492 on the reel 49.

[0044] In addition, a signal transmission device connected to the nurse station is provided on the second intelligent module 42. When the patient is struggling violently, the second intelligent module 42 will transmit the patient's information to the nurse station, and the nurse on duty will quickly rush to the corresponding patient's ward according to the information to prevent the patient from having an accident.

[0045] like Figures 2 to 8 As shown, a first air cushion 11 is bonded inside the first protective sleeve 1, a second air cushion 12 is bonded on the first air cushion 11, a ventilation hole 121 is provided on the second air cushion 12, and both the first air cushion 11 and the second air cushion 12 are connected to the first air pump 43. Specifically, the first air pump 43 inflates the first air cushion 11, so that the first air cushion 11 can hold up the palm of the patient and improve the patient's comfort. When the weather is hot, the air pressure valve 44 corresponding to the second air cushion 12 is opened by operating the operation panel 48, and the first air pump 43 blows air into the ventilation hole 121, and then the air flows out from the ventilation hole 121, which has a certain cooling effect on the patient.

[0046] It is worth noting that for patients who need injection treatment on the back of the hand, the nurse will insert the injection needle into the vein on the back of the patient's hand. However, the hospital's human resources are limited, and nurses cannot always stay with the patients. For some patients who are unconscious or do not cooperate with the treatment, the patient's hand movements will cause the needle to bulge, causing local tissue damage, pain, and even infection. This not only requires the replacement of drugs and needles, but may also lead to medical accidents if infected.

[0047] In order to solve this problem, a third air cushion 13 and a pair of fixing boxes 14 are bonded to the second air cushion 12, and the third air cushion 13 is between the pair of fixing boxes 14. A slider 141 is slidably connected in the fixing box 14, and a buckle 15 is integrally formed on the slider 141, and a first locking belt 16 is fastened to the pair of buckles 15. A fourth air cushion 142 is bonded to the lower panel of the fixing box 14, and the slider 141 is bonded to the fourth air cushion 142. The fourth air cushion 142 is provided with a connecting pipe 1421 connected to the first air pump 43.

[0048] Specifically, the patient's palm is placed between the first locking belt 16 and the third air cushion 13, so that the joint where the patient's fingers and palm are connected presses the third air cushion 13. The first air pump 43 is started, and the third air cushion 13 will swell upwards, pushing up the patient's palm. At this time, the patient's palm has a natural curvature and will not be flat on the second air cushion 12. Then the first locking belt 16 is tightened, so that the first locking belt 16 fits the joint where the patient's back of the hand and fingers are connected. This not only fixes the patient's hand and prevents bulging caused by habitual movement, but also improves the patient's comfort with a curved palm.

[0049] Furthermore, the bulging height of the fourth air cushion 142 can be adjusted according to the thickness of the patient's palm, so that the slider 141 slides up and down in the fixing box 14, thereby changing the distance between the first locking belt 16 and the third air cushion 13. By inflating and deflating the fourth air cushion 142 separately, even if the palm thickness of different patients is different, it can be fully applicable.

[0050] In addition, when used in hot summer, the air blown out from the ventilation holes 121 after the third air cushion 13 lifts the patient's palm can also better cool the patient's palm, preventing the patient's palm from sweating in the first protective cover 1 and the second protective cover 2, causing infection at the pinhole.

[0051] Furthermore, the monitoring assembly also includes a monitor 47, on which a regulator 471 is installed, and a tube hole 401 is opened on the operation box 4. When the patient injects saline on the back of the hand, the infusion tube connected to the saline passes through the tube hole 401. The monitor 47 in the operation box 4 can detect whether there is still liquid in the infusion tube. Once the monitor 47 detects that there is no liquid in the infusion tube, it will send a signal, and the regulator 471 can block the infusion tube. Prevent air from entering the blood vessels along the infusion line to cause air embolism. Air entering the blood will affect the heart and the blood circulation of the whole body, and in severe cases, it can cause death.

[0052] When the regulator 471 blocks the infusion tube, the signal transmission device on the second intelligent module 42 will send a signal to the nurse station to remind the nurse to come and remove the needle or replace the saline solution.

[0053] At the same time, a cable 31 is installed on the zipper 3, a lock hole matching the cable 31 is opened on the operation box 4, and a second air pump 46 for locking the cable 31 is installed in the operation box 4. The second air pump 46 can lock the cable 31, and the combination and separation of the first protective cover 1 and the second protective cover 2 can be realized through the cable 31.

[0054] A method for using an intelligent arm restraint comprises the following steps:

[0055] S1, putting on the mask, starting the air supply assembly to exhaust the air in the zipper 3, allowing the patient's palm to pass through the zipper 3 and be placed on the first air cushion 11;

[0056] S2, tighten, start the air supply assembly, and the zipper 3 expands after being inflated, so that the patient's palm cannot be withdrawn from the zipper 3;

[0057] S3, once fixed, fix one end of the second locking belt 492 on the bed, then start the rotary motor 491 to rotate the reel 49, adjust the length of the second locking belt 492 leaking from the operation box 4, so that the moving distance of the patient's arm is less than the distance from the patient's hand to the treatment channel;

[0058] S4, adjusting, by manipulating the operation panel 48 to inflate the third air cushion 13, and supporting the palm of the patient, so that the palm of the patient forms a natural curvature;

[0059] S5, secondary fixation, tightening the first locking belt 16, so that the first locking belt 16 tightens the joint where the patient's fingers and the back of the hand are connected.

[0060] When in use, first pass the patient's hand through the annular airbag 5, so that the patient's palm is placed in the first protective sleeve 1 and the second protective sleeve 2, and start the first air pump 43. The first air pump 43 inflates the annular airbag 5. After the annular airbag 5 is inflated, it can wrap the patient's forearm to prevent the patient's hand from being pulled out of the first protective sleeve 1 and the second protective sleeve 2.

[0061] Then, the end of the second locking belt 492 away from the reel 49 is tied to the bed, so that the operation box 4 is close to the binding position of the second locking belt 492, and then the straight-line distance between the patient's hand and the treatment pipeline on the patient's body is input into the second intelligent module 42 through the operation panel 48. After calculation by the second intelligent module 42, the length of the second locking belt 492 released from the reel 49 can be obtained, so that the patient's arm can move within the range where it cannot touch the treatment pipeline.

[0062] If the patient wants to break free from the intelligent arm restraint, the rotary motor 491 is started to rotate the reel 49, shrinking the second locking belt 492, so that the operation box 4 gradually approaches the position where the second locking belt 492 is tied to the bed, and the second locking belt 492 is continuously tightened inside the operation box 4 until the patient's arm is fixed on the bed.

[0063] When the patient's back of the hand is injected with saline, the first air pump 43 is started, and the third air cushion 13 lifts the patient's palm so that the patient's palm has a natural curvature, and then the first locking belt 16 is tightened so that the first locking belt 16 fits the joint where the patient's back of the hand and fingers are connected. This not only fixes the patient's hand and prevents tympanitis caused by habitual movement, but also the curved palm can improve the patient's comfort.

[0064] At the same time, through the cooperation of the monitoring component and the second intelligent module 42, the patient's arm movement trajectory can also be recorded, and the patient's abnormal condition can be reported to the nurse station in time.

[0065] Compared with the prior art, the intelligent arm restraint and the method of using the same of the present invention can be individually adjusted according to the patient's age, physique, degree of limb activity, etc., thereby improving the patient's comfort and ensuring that the treatment tube will not be pulled out by the patient, thereby more safely protecting the patient's life.

[0066] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
