Description

Technical Field

[0001] This utility model relates to the field of restraint equipment technology, and in particular to a visual restraint protection device. Background Technology

[0002] Intensive care is a specialized medical model implemented for critically ill patients, aiming to provide concentrated and meticulous treatment and care by utilizing advanced medical technology and modern monitoring and resuscitation equipment. Maintaining the patient's physical and psychological stability is crucial during this process, especially when the patient is unconscious or at risk of self-harm; in such cases, the use of restraint devices is particularly critical.

[0003] The primary function of restraint devices is to prevent self-harm due to impaired consciousness and ensure the smooth progress of treatment. However, existing restraint devices have design limitations and cannot effectively restrain a patient's fingers or feet. This allows the patient's fingers and feet to move freely. While this freedom may provide some comfort, in a restless state, the patient may unintentionally injure their own hands or feet or cause harm to caregivers. This not only affects the patient's safety but also subsequent treatment. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] like Figures 1 to 3 As shown, an embodiment of this utility model discloses a visual restraint protection device 100, including a restraint component 1, a strap component 2, and a fixing strap 3.

[0036] The restraint assembly 1 includes a transparent restraint capsule 11 with a cavity inside for accommodating the patient's hand or foot. The restraint capsule 11 includes a first flap 111 and a second flap 112, which are rotatably connected to open or close the cavity.

[0037] The constraint capsule 11 has a constraint position and a release position. In the constraint position, the first lobe 111 and the second lobe 112 are closed. In the release position, the first lobe 111 and the second lobe 112 are separated.

[0038] The strap assembly 2 is capable of wrapping or releasing the first lobe 111 and the second lobe 112 so that the restraint capsule 11 can switch between a restrained position and a released position.

[0039] One end of the fixing strap 3 is connected to the strap assembly 2, and the other end of the fixing strap 3 is connected to the fixing structure.

[0040] For example, such as Figure 1 and Figure 2As shown, the restraint capsule 11 is made of transparent material. Through the transparent restraint capsule 11, medical staff can clearly see the skin condition of the patient's hands or feet, and promptly detect any abnormalities, such as skin discoloration, swelling or other potential problems, to ensure that necessary measures can be taken in a timely manner and avoid complications caused by improper restraint.

[0041] The restraint pouch 11 has an internal cavity specifically designed to accommodate the patient's hands or feet. The size of the restraint pouch 11 can be designed according to actual needs; for example, the restraint pouch 11 comes in various sizes to accommodate patients of different physiques.

[0042] The shape of the restraint capsule 11 varies depending on the restraint location. For example, when the restraint capsule 11 restrains a finger, it is spherical, and when the restraint capsule 11 restrains a foot, it is elliptical.

[0043] The first lobe 111 and the second lobe 112 are connected by a rotatable connection, such as a hinge, which allows the cavity to be opened or closed.

[0044] When in the restraint position, the first petal 111 and the second petal 112 are closed, and the first petal 111 and the second petal 112 are wrapped together by the strap assembly 2 to ensure that the patient's hands or feet are effectively restrained and to prevent accidental movement or injury.

[0045] When in the release position, untie the strap assembly 2, and then rotate the first petal 111 or the second petal 112 to fully open the cavity, facilitating examination, treatment, or allowing the patient to move freely.

[0046] One end of the restraint strap 3 is connected to the binding assembly 2, and the other end is connected to a fixed structure to further restrain the patient's limbs. The fixed structure is a stationary object near the patient with a large load-bearing capacity, such as the railings on the patient's bed or the railings on the walls surrounding the bed.

[0047] When using the visual restraint protection device 100, first open the first petal 111 and second petal 112, then place the patient's hand or foot into the cavity, then close the first petal 111 and second petal 112, and finally use the strap assembly 2 to fix the first petal 111 and second petal 112 together, thus restraining the patient's hand or foot. The fixing strap 3 can be connected to the fixing structure before or after the above process.

[0048] When the patient is moving freely, first untie the strap assembly 2, then separate the first petal 111 and the second petal 112, and then remove the patient's hand or foot from the cavity, allowing the patient to move freely.

[0049] Existing restraint devices in this field have design limitations and cannot effectively restrain a patient's fingers or feet. This allows the patient's fingers and feet to move freely. While this freedom may provide some comfort, in a restless state, the patient may unintentionally injure their own hands or feet or cause harm to caregivers. This not only affects the patient's safety but also subsequent treatment.

[0050] The visual restraint protection device 100 implemented in this utility model uses a restraint bag 11 to restrain the patient's fingers or feet. At the same time, the restraint bag 11 itself can also protect the patient's hands or feet, thereby preventing the patient from accidentally injuring their hands or feet, thus ensuring the safety of the patient and the caregiver, and thus facilitating subsequent treatment.

[0051] Moreover, the visual restraint protection device 100 implemented in this utility model utilizes the structure of the first petal 111 and the second petal 112, as well as the rotatable connection method, to quickly open or close the restraint capsule 11 when needed, making it convenient for medical staff to perform related operations.

[0052] Furthermore, the design of the strap assembly 2 and the fixing strap 3 allows the visual restraint protection device 100 to flexibly adapt to different fixing structures, providing reliable restraint effects whether it is a bedside railing or a wall-mounted fixing point. Therefore, this invention not only improves patient safety but also reduces the workload of medical staff, making it a medical restraint device that combines safety and practicality.

[0053] In some embodiments, the constraint capsule 11 has an open end and a rotating end arranged opposite each other in a first direction, and the first petal 111 and the second petal 112 are rotatably connected at the rotating end of the constraint capsule 11.

[0054] The first lobe 111 has a first notch 1112, and the second lobe 112 has a second notch 1122. In the constrained position, the first notch 1112 and the second notch 1122 are connected to form a first opening at the opening end of the constrained bladder 11.

[0055] The constraint assembly 1 includes a sleeve component 12, which is disposed at the open end of the constraint bladder 11. The sleeve component 12 includes a connector 121 and a limiting member 122. One end of the connector 121 is fixedly connected to the first petal 111 and is disposed near the edge of the first recess 1112. One end of the limiting member 122 is fixedly connected to the second petal 112 and is disposed near the edge of the second recess 1122.

[0056] In the restraint position, the connector 121 and the limiting member 122 are arranged opposite to each other and both fit against the patient's wrist or ankle so that the restraint assembly 1 can restrain the patient's hand or foot.

[0057] In the release position, the connector 121 and the limiting member 122 separate to release the patient's hand or foot.

[0058] For example, such as Figure 1 As shown, for ease of description, the first direction is the left and right direction in the figure.

[0059] The left end of the restraint capsule 11 is its opening, and the right end is its rotating end. The first petal 111 and the second petal 112 are hinged together at the right end of the restraint capsule 11. In the restrained position, the first petal 111 and the second petal 112 are in contact at the left end of the restraint capsule 11. In the released position, the first petal 111 and the second petal 112 are separated at the left end of the restraint capsule 11.

[0060] In the restraint position, the left end of the first lobe 111 has a first notch 1112, and the left end of the second lobe 112 has a second notch 1122. The first notch 1112 and the second notch 1122 communicate to form a first opening, so that the patient's wrist or ankle can pass through the first opening into the restraint pouch 11.

[0061] The sleeve component 12 is located at the left end of the restraint pouch 11. The sleeve component 12 includes two parts: one is a connector 121 located on the first lobe 111, which is connected to the edge of the first recess 1112; the other is a limiting component 122 located on the second lobe 112, which is connected to the edge of the second recess 1122.

[0062] In the constrained position, as the first petal 111 and the second petal 112 close, the connector 121 and the limiting member 122 also close together. At this time, the connector 121 and the limiting member 122 define a channel, and the patient's wrist or ankle is located in the channel. The connector 121 and the limiting member 122 fit against the patient's wrist or ankle.

[0063] In the release position, as the first petal 111 and the second petal 112 separate, the connector 121 and the limiting member 122 also separate to release the patient's hand or foot.

[0064] The visual restraint protection device 100 implemented in this utility model features a simple and reliable closing and opening process for the sleeve component 12, reducing the risk of misoperation during operation. Simultaneously, the channel design ensures uniform restraint distribution, preventing skin damage or other discomfort caused by excessive local pressure.

[0065] In some embodiments, the strap assembly 2 includes a protective strap 21 and a restraint strap 22. The protective strap 21 is connected to the other end of the connector 121. The protective strap 21 has a first end and a second end in its extension direction. The first end of the protective strap 21 is fixedly connected to the restraint strap 22. The protective strap 21 can be wrapped around the patient's wrist or ankle. A portion of the restraint strap 22 can be wrapped around the outside of the protective strap 21, and another portion of the restraint strap 22 can be wrapped around the outside of the sleeve component.

[0066] For example, such as Figure 1 As shown, when the protective strip 21 is unfolded, along Figure 1 Extending in the front-back direction, the first and second ends of the protective belt 21 are the front and rear ends of the protective belt 21, and one of the front and rear ends of the protective belt 21 is connected to the restraint belt 22.

[0067] The protective band 21 is wider than the restraint band 22. The protective band 21 contains sponge. When the protective band 21 is wrapped around the patient's arm or calf, the sponge can improve the patient's comfort and reduce unnecessary pressure and discomfort.

[0068] The length of the restraint strap 22 is greater than the length of the protective strap 21. In the restraint position, the protective strap 21 can first be wrapped around the patient's wrist or ankle. Then, a part of the restraint strap 22 is wrapped around the outside of the sleeve component to close the first petal 111 and the second petal 112. The other part of the restraint strap 22 is wrapped around the outside of the protective strap 21 to enhance the restraint effect.

[0069] In some embodiments, the protective strip 21 further includes a connecting portion 211, which is disposed between the first end and the second end of the protective strip 21, and is fixedly connected to the other end of the connector 121.

[0070] For example, such as Figure 1 As shown, the connecting part 211 is located in the middle of the protective belt, and the connecting part 211 is fixedly connected to the other end of the connector 121. One end of the connector 121 is fixedly connected to the first petal 111. Thus, the protective belt 21, the connector 121 and the first petal 111 can be connected together, facilitating operation.

[0071] In some embodiments, the limiting member 122 includes a connecting piece 1221 and a limiting hook 1222. The connecting piece 1221 has a first surface and a second surface arranged opposite to each other. The limiting hook 1222 is disposed on the second surface. In the restraint position, the first surface is in contact with the patient's wrist or ankle, and the restraint strap 22 is wound around the second surface at least once. The limiting hook 1222 is used to prevent the restraint strap 22 from falling off the second surface. Thus, by using the limiting hook 1222, the restraint strap 22 can be prevented from falling off the second surface, ensuring the robustness and reliability of the entire visual restraint protection device 100, thereby improving the safety of the visual restraint protection device 100 and thus helping to protect the patient or caregiver.

[0072] In some embodiments, the limiting hook 1222 includes a first hook portion 12221 and a second hook portion 12222. One end of the first hook portion 12221 is connected to the second surface, and the other end of the first hook portion 12221 extends from the second surface in a direction away from the first surface. The second hook portion 12222 is connected to the other end of the first hook portion 12221, and the second hook portion 12222 extends in a direction close to the restraint pouch 11.

[0073] For example, such as Figure 3 As shown, for ease of description, the up and down directions are as follows: Figure 1 As shown, one side of the protective band 21 contacts the patient's skin, and the other side of the protective band 21 is provided with a limiting ring 212. When the restraint band 22 is wrapped around the protective band 21, at least one turn of the restraint band 22 passes through the limiting ring 212, ensuring the fixation effect of the restraint band 22 and preventing it from slipping off. This not only improves the stability and reliability of the visual restraint protection device 100, but also ensures the patient's safety and reduces potential risks caused by loosening of the restraint band 22.

[0074] In some embodiments, the first lobe 111 has a first end face 1111, and the second lobe 112 has a second end face 1121. In the constrained position, the first end face 1111 and the second end face 1121 are fitted together. One of the first end face 1111 and the second end face 1121 is provided with a groove, and the other of the first end face 1111 and the second end face 1121 is provided with a protrusion that mates with the groove. Thus, the groove and the protrusion facilitate the strengthening of the connection between the first lobe 111 and the second lobe 112, thereby preventing misalignment of the first lobe 111 and the second lobe 112 in the constrained position.

[0075] In some embodiments, the first petal 111 and the second petal 112 are each provided with a plurality of vent holes 113, which are in communication with the cavity.

[0076] For example, such as Figure 1As shown, both the first petal 111 and the second petal 112 are provided with multiple ventilation holes 113, which communicate with the cavity to ensure air circulation within the cavity. Therefore, by providing ventilation holes 113, skin dampness and discomfort caused by prolonged wearing of the visual restraint protection device 100 can be reduced, improving patient comfort.

[0077] In some embodiments, the restraint pouch 11 is a transparent rubber restraint pouch 11. This allows medical staff to easily observe the color of the restrained area and whether swelling has occurred. Through the transparent restraint pouch 11, medical staff can clearly see the skin condition of the patient's hands or feet, and promptly detect any abnormalities, such as skin discoloration, swelling, or other potential problems. This design not only improves patient safety but also simplifies the monitoring work of medical staff, ensuring that necessary measures can be taken in a timely manner to avoid complications caused by improper restraint.

[0078] The material of the visual restraint protection device 100 can be selected according to actual needs. For example, the restraint capsule 11 is made of transparent rubber, the connector 121 is made of cloth, and the limiting member 122 is made of stainless steel. The restraint capsule 11, the connector 121, and the protective belt 21 are all connected by stitching, and the limiting member 122 and the restraint capsule 11 are connected by adhesive bonding.

[0079] In other embodiments, the restraint strap 22 is a Velcro strap. Therefore, when it is necessary to release or adjust the restraint pouch 11, simply unfasten the Velcro strap, improving ease of operation.

[0080] In other embodiments, the visual restraint protection device 100 also includes an exercise ball, and a restraint pouch 11 for restraining the patient's hands, with the exercise ball disposed within the restraint pouch 11.

[0081] For example, the visual restraint protection device 100 also includes an exercise ball, which can be a solid or hollow ball. When the restraint pouch 11 is used to restrain the patient's hand, the exercise ball is placed inside the restraint pouch 11. This design not only provides effective restraint but also takes into account the patient's rehabilitation needs. Specifically, when the patient's hand is restrained inside the restraint pouch 11, they can perform rehabilitation exercises for their fingers and hand by grasping and squeezing the exercise ball, reducing discomfort caused by prolonged immobility. In addition, the exercise ball can also distract the patient, reducing restlessness and anxiety caused by restraint, thereby reducing the occurrence of agitated behavior.

[0082] In other embodiments, when the visual restraint protection device 100 is used to restrain a patient's foot, the volume of the restraint bladder 11 is larger than the volume of the foot, and there is still a certain gap between the patient's heel and the bladder wall of the restraint bladder 11, thereby reducing the risk of pressure injury to the patient's heel.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
