Description

Technical Field

[0001] The present invention relates to a medical restraint product, in particular to an adjustable upper limb intelligent restraint device for limiting or restraining the range of motion of an upper limb, belonging to the field of medical products. Background Art

[0002] In clinical practice, restraint products are often needed to restrict or protect patients who are in a coma, unclear consciousness, have limited upper limb movement, are agitated or aggressive after surgery during treatment and care to ensure their safety and facilitate the treatment process.

[0003] Existing restraint products of this type mainly include restraint belts, restraint gloves and restraint vests.

[0004] 1. Restraint belt: Suitable for restraining wrists or upper arms. It fixes the patient's wrists or upper arms to the bed rails through Velcro, buckles, etc. Although it is simple to use and low cost, it has a strong sense of restraint and puts a lot of psychological pressure on patients. Long-term use may cause skin compression or blood circulation obstruction, so it is only suitable for short-term restraint.

[0005] 2. Restraint gloves: Suitable for patients who need to restrict hand movement to prevent them from scratching wounds, removing tubes or self-injury. In addition to covering the entire hand, they also need to be fixed to the bed rails with straps. Although they can restrain the patient's hands, have less restriction on wrist and arm movement, and are more comfortable, the blood circulation of the hands is greatly affected and needs to be checked regularly. At the same time, if the patient's discomfort or anxiety is more serious, they are only suitable for patients with obvious hand agitation and need protective restraint.

[0006] 3. Restraint vest: used to restrict upper body movement and prevent patients from sitting up or turning over. Its structure is similar to a vest, covering the torso and upper arms, and fixed to the bed rails with straps. Although it protects the torso and allows a certain degree of forearm movement, the restraint vest covering the torso and upper arms may restrict breathing, causing breathing difficulties and oppression, a strong sense of restraint, and a greater psychological burden and pressure. Long-term use has more prominent disadvantages.

[0007] Although the above products meet certain treatment and restraint needs, patients generally have a strong sense of restraint and anxiety. In order to improve the comfort of the treatment process and reduce the psychological pressure caused by the restraint process, a new adjustable upper limb intelligent restraint that can limit and restrain the range of motion of the patient's upper limbs has become the main purpose of this invention.

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 The schematic diagram of the adjustable upper limb intelligent restraint device in the present invention is shown in FIG. Figure 1 ; Figure 2 The schematic diagram of the adjustable upper limb intelligent restraint device in the present invention is shown in FIG. Figure 2 . DETAILED DESCRIPTION

[0021] The following is combined with Figure 1 , Figure 2 The present invention is further described in detail: The adjustable upper limb intelligent restraint device of the present invention comprises a hand restraint body, an arm restraint body matched with the hand restraint body, and an intelligent control system. The hand restraint body is used to restrain the patient's hand, the arm restraint body matched with the hand restraint body restrains or controls the patient's arm, and the intelligent control system detects the restraint process in real time and sends monitoring information or alarms to the remote nurse station, thereby improving the nursing and monitoring efficiency. Specifically: The hand restraint body includes a hand restraint support plate 13 and a flexible transparent flap 9 that is movably shielded above the hand restraint support plate 13. The hand restraint support plate 13 can lift and restrain the patient's hand for protection, and the flexible transparent flap 9 can shield and protect the patient's hand placed on the hand restraint support plate 13 and various infusion lines that may be plugged into the hand.

[0022] In this example, the hand restraint support plate 13 is made of medical plastic, and its main body shape is 'U'-shaped. The inner side surface of the 'U'-shaped hand restraint support plate 13 is covered with a replaceable flexible protective layer 11, and a wrist pad 19 is provided on the replaceable flexible protective layer 11 corresponding to the position of the patient's wrist. At the same time, two restraint straps 15 corresponding to the positions of the patient's wrist and palm are provided on the inner side surface of the 'U'-shaped hand restraint support plate 13, respectively. The restraint straps 15 are in a ring form and are bonded and the bonding positions are adjusted to each other using a universal buckle. To increase comfort, a medical silicone layer is provided on the surface of the restraint strap 15 that contacts the patient's hand. In order to further meet the needs of patients and relieve the psychological pressure of the treatment and restraint process, an elastic grip body 12 for hand pressure relief rehabilitation is also provided on the inner side surface of the 'U'-shaped hand restraint support plate 13. In this example, the gripping body 12 is in a human shape, and the human-shaped gripping body 12 corresponds to the position of the patient's palm. Through the gripping and squeezing of the palm, the purpose of relieving the patient's pressure and enhancing the hand strength is achieved.

[0023] In this example, the flexible transparent flap 9 is made of rubber material. For easy installation and use, the fixed end of the flexible transparent flap 9 is set on one side protruding end of the 'U'-shaped hand restraint support plate 13, and the other side protruding end of the 'U'-shaped hand restraint support plate 13 is provided with a first buckle 14 that matches the movable end of the flexible transparent flap. After the clamping is completed, the flexible transparent flap 9 can cover the top of the main body of the 'U'-shaped hand restraint support plate 13, and at the same time, the front and rear ends of the 'U'-shaped hand restraint support plate 13 can also remain connected to each other, ensuring ventilation and the introduction and exit of various treatment pipelines.

[0024] In specific practice, in order to further meet the use needs and improve the use safety, a second buckle 8 is further provided on the opposite side of the hand restraint support plate 13 corresponding to the position of the first buckle 14. When the flexible transparent flip cover 9 is opened, its movable end can be reversely clamped on the second buckle 8, thereby limiting the spatial position of the flexible transparent flip cover 9 after opening, which facilitates clinical care and operation.

[0025] In this example, the arm restraint body adopts an adjustable telescopic sleeve 5 as the main body, and a winding restraint belt 1 is provided near the top of the adjustable telescopic sleeve 5. At the same time, a belt ring 21 for fixing the treatment pipeline is provided on the adjustable telescopic sleeve 5, and the belt ring 21 is bonded and fixed by a universal buckle. The bottom of the adjustable telescopic sleeve 5 is fixed on the hand restraint support plate 13 and is located outside the fixed end of the flexible transparent flap 9. When the flexible transparent flap 9 is clamped with the second buckle 8, the lower end of the adjustable telescopic sleeve 5 can be blocked from above, reducing the space occupied by the flexible transparent flap 9 after it is opened. Of course, in order to improve the flexibility of use, the adjustable telescopic sleeve 5 can also be connected to the hand restraint support plate 13 in a movable manner. When the adjustable telescopic sleeve 5 is not needed, the adjustable telescopic sleeve 5 can be removed at any time, which improves the clinical applicability.

[0026] To further improve the comfort of use, in this example, a replaceable protective cover 2 is wrapped between the wrap-around restraint belt 1 and the adjustable telescopic sleeve 5 and on the sleeve surface of the adjustable telescopic sleeve 5. The wrap-around restraint belt 1 is wrapped around the replaceable protective cover at the top, and the belt ring 21 is attached to the replaceable protective cover in the middle.

[0027] In order to further improve the performance, in this example, a scale 3 is further provided on the adjustable telescopic sleeve 5 to facilitate accurate adjustment of the length of the adjustable telescopic sleeve 5 and ensure accurate and reliable restraint of the arm.

[0028] In this example, the intelligent control system includes a controller 6 and a wireless transmission module, an alarm module, a battery, a pressure sensor 16, a heart rate sensor 18 and a body temperature sensor 17 that are connected to the controller 6 by signal. Among them, the controller 6, the wireless transmission module, the alarm module and the battery are respectively arranged in the hand restraint support plate 13 below the adjustable telescopic sleeve 5. The pressure sensor 16 is arranged in the restraint belt 15. The heart rate sensor 18 and the body temperature sensor 17 are respectively arranged on the inner side of the hand restraint support plate 13. In order to ensure the normal contact between the heart rate sensor 18 and the body temperature sensor 17 and the patient's wrist, the replaceable flexible protective layer 11 corresponding to the position of the heart rate sensor 18 and the body temperature sensor 17 is hollow. The alarm module uses a speaker 7 for sound alarm prompts to facilitate patients or nursing staff to find out in time and avoid accidents. Of course, according to the patient's use needs, the intelligent control system may also include a triaxial accelerometer, a humidity sensor and / or a blood oxygen saturation sensor. The triaxial accelerometer can sense the movement of the patient's hands and arms at any time to avoid possible agitation. The humidity sensor can monitor the humidity of the patient's restraints at all times to prevent pressure sores. The blood oxygen saturation sensor can monitor the patient's blood oxygen saturation information at any time, providing assistance for safe and reliable monitoring and better care.

[0029] When in use, place the patient's hand on the hand restraint support plate 13, use the restraint belt 15 to fix the patient's hand and wrist, keep the patient's wrist in full contact with the bowl pad 19, then flip the flexible transparent flip cover 9 and clamp it with the first buckle 14 to complete the hand restraint process; then, stretch and extend the adjustable telescopic sleeve 5 to an appropriate position, wrap it around the patient's upper arm through the wrapping restraint belt 1, and complete the upper arm restraint process. Among them, the replaceable protective cover 2 is in direct contact with the patient's arm, avoiding friction damage caused by the contact between the adjustable telescopic sleeve 5 and the patient's arm. If the patient's hand needs to be connected to a treatment line, the line can be led out or inserted from the bottom of the flexible transparent flip cover 9, and after being limited by the belt ring 21 in the middle of the adjustable telescopic sleeve 5, the guidance and protection of the treatment line are completed. During this period, the patient's upper arm can be free from restraint restrictions, and only the forearm and wrist are restrained. In addition to normal activities, the fingers can be rehabilitated and relieved of pressure by holding the "human" shaped grip body 12, which greatly improves the comfort of restraint treatment. The controller 6 can collect the monitoring information transmitted by the pressure sensor 16, the temperature sensor 17 and the heart rate sensor 18 at any time, and transmit the information to the client of the nurse station through the wireless transmission module at any time, so as to ensure that the monitoring process is carried out in a timely and reliable manner. If the monitoring process exceeds the limit, the speaker 7 will issue an alarm message to prompt the patient or the nursing staff to handle it in time. Of course, when performing nursing operations on the patient's hands, the flexible transparent flip cover 9 can be opened, and the active end of the flexible transparent flip cover 9 can be clamped on the second buckle 8 in the reverse direction, which facilitates the nursing operation process and improves the safety of the use of the flexible transparent flip cover 9.
