Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to a medical restraint and protection device. Background Technology
[0002] In clinical intravenous infusion therapy, the placement and position of the patient's arm are crucial factors affecting the safety and comfort of the infusion. Currently, in common infusion scenarios, patients typically sit with the arm requiring the infusion resting flat on the chair armrest to maintain a relatively stable posture during the infusion. However, infusion processes often take a long time, ranging from tens of minutes to several hours. Maintaining the same posture for an extended period can easily lead to mental fatigue, especially in patients recovering from illness or those with weaker constitutions, where drowsiness and nodding off are more common. In this state, the patient's arm loses voluntary control and can easily slip unintentionally from the chair armrest. This slip can directly pull on the infusion tubing, potentially causing needle displacement, tubing dislodgement, or even vascular damage, disrupting the treatment process and causing additional pain and risks for the patient.
[0003] To address this issue, some infusion support devices with arm restraint functions have emerged in the prior art. For example, a temperature-controlled self-restraining psychiatric infusion device disclosed in Chinese Patent Publication No. CN117752900A is a typical example. This device is designed to not only support and restrain the patient's hand, preventing the arm from slipping through its restraint structure, but also considers comfort during the infusion process by incorporating a temperature control function. It can blow cold or hot air as needed to cool or heat the patient's hand, thus improving the patient's hand comfort during infusion to some extent.
[0004] Despite improvements in positioning and temperature control, these devices still have significant limitations in practical applications. The core issue is that the patient's arm needs to be placed on the device's massage plate, and the area where the arm contacts the plate is completely covered. This prevents the skin in that area from receiving the cool or warm air from the device, hindering effective temperature regulation. When cooling is needed, the contact area cannot dissipate heat, easily leading to sweat buildup and discomfort for the patient; when maintaining warmth is required, the area cannot receive heat evenly, affecting overall temperature control. This design flaw significantly diminishes the device's ability to improve patient comfort and fails to fundamentally solve the discomfort caused by arm restraint and uneven temperature control during prolonged intravenous infusions. Summary of the Invention
[0005] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a medical restraint protection device.
[0006] The technical solution adopted by the present invention is as follows: The present invention provides a medical restraint protection device, including a restraint box and a shaking mechanism. The shaking mechanism is disposed inside the restraint box and includes a driving component, an air chamber and a water chamber. The water chamber is fixedly disposed on the left and right sides of the air chamber. Slide rails are fixedly disposed on the inner walls of the left and right sides of the restraint box. The bottom of the water chamber is provided with a sliding groove that slides with the slide rails. The driving component is disposed at the bottom of the restraint box and connected to the bottom of the air chamber.
[0007] Furthermore, the air chamber has cylindrical shells that are partially exposed to the outside and can be rotated. The top of the air chamber has a through-hole for the top of the cylindrical shell to rotate and extend out. Both ends of the cylindrical shell are connected to water inlet pipes. The other end of the water inlet pipe passes through the inner walls of the air chamber and the water chamber in sequence through a sealed bearing and extends into the water chamber. The top of the air chamber has ventilation holes.
[0008] Furthermore, the drive assembly includes a motor, an eccentric disc, a connecting rod, a mounting plate, and a fixing frame. The fixing frame is fixed to the bottom of the constraint box and located below the air chamber. The fixing frame is n-shaped, and the mounting plate is U-shaped. The mounting plate is slidably mounted on the fixing frame from the top, and the top of the mounting plate is fixedly connected to the bottom of the air chamber. The motor is fixedly mounted on the bottom of the mounting plate. The eccentric disc is fixedly mounted on the output shaft of the motor and located below the fixing frame. The top of the eccentric disc is provided with an annular groove. The top of the connecting rod is fixedly mounted on the fixing frame, and the bottom of the connecting rod is slidably engaged with the annular groove.
[0009] Furthermore, the drive assembly also includes an air supply unit located at the bottom of the air chamber and connected to the motor. The air supply unit includes an air supply duct, a rotating shaft, a drive shaft, fan blades, and a support frame. The top of the air supply duct is connected to the bottom of the air chamber and communicates with its interior. The support frame is cross-shaped and fixedly located inside the air supply duct. The rotating shaft is rotatably mounted in the middle of the support frame via bearings. The fan blades are fixed to the top of the rotating shaft. A bevel gear one is fixedly provided at the bottom of the rotating shaft. The drive shaft rotates horizontally through the side wall of the air supply duct via bearings. A bevel gear two is fixedly provided at one end of the drive shaft, and bevel gear one meshes with bevel gear two. A bevel gear three is fixedly provided at the other end of the drive shaft. A bevel gear four is fixedly provided on the output shaft of the motor, and bevel gear three meshes with bevel gear four.
[0010] Furthermore, stirring blades are distributed on one end of the water inlet pipe located inside the water tank.
[0011] Furthermore, the top of the constraint box is open, and a transparent cover is hinged to one side of its top.
[0012] Furthermore, a strap is provided on one side of the constraint box, and a connecting ring is fixedly provided on the other side of the constraint box.
[0013] Furthermore, an infusion tube receiving groove is provided on one side of the transparent cover, and an arm clearance opening is provided on the front side wall of the restraint box.
[0014] Furthermore, a hand placement platform is fixedly provided inside the constraint box, and the hand placement platform is located behind the shaking mechanism.
[0015] Furthermore, the height of both water tanks is greater than the height of the air tank, and the top of the water tank is equipped with a water inlet, and the interior of the water tank is equipped with a heating element.
[0016] The beneficial effects achieved by the present invention using the above structure are as follows:
[0017] 1. This invention, through the overall structural design of the restraint box, combined with straps and connecting rings, can securely fix the restraint box to the armrest of a chair. When the patient is receiving an IV infusion, the arm is placed inside the box and the hand is placed on the hand resting platform. The transparent cover plate further assists in restraint, which can fundamentally prevent the problem of the patient's arm slipping due to fatigue and drowsiness. It completely solves the risk of IV infusion accidents such as the pulling of the IV tube and the displacement of the needle caused by the slipping of the arm in the background technology, and provides reliable safety protection for the IV infusion process.
[0018] 2. This invention utilizes the synergistic effect of the motor, eccentric disc, and other structures in the drive assembly to move the air chamber and water chamber back and forth within the constraint box, thereby causing the cylindrical shell inside the air chamber to roll on the patient's arm. This rolling not only simulates a massage motion, relieving muscle stiffness and numbness caused by maintaining the same posture for a long time, but also continuously changes the contact position between the cylindrical shell and the arm, ensuring even force distribution across all parts of the arm and avoiding poor blood circulation caused by localized pressure. This effectively improves the discomfort that often occurs when the arm is fixed in a traditional device.
[0019] 3. This invention heats water with heating elements or directly injects cold water. The heat or cold is quickly conducted to the arm through the water tank and cylindrical shell made of aluminum alloy. At the same time, the rolling of the cylindrical shell ensures that all parts of the arm can make uniform contact with the temperature control source, which solves the defect of uneven temperature control at the contact parts in traditional devices in the background art.
[0020] 4. This invention utilizes the ventilation holes at the top of the air chamber, which are not blocked by the rolling cylindrical shell or the arm. In conjunction with the air supply unit, airflow is continuously delivered into the air chamber, allowing the airflow to be evenly distributed across the surface of the arm. In particular, it can act on the contact area that is covered in traditional devices. When cooling, it can quickly dry sweat, and when keeping warm, it can accelerate heat diffusion, significantly improving temperature control efficiency and patient comfort.
[0021] 5. This invention utilizes the stirring blades on the water inlet pipe to rotate synchronously with the cylindrical shell, which can quickly stir the water in the water tank, allowing the temperature of hot or cold water to spread rapidly and evenly within the water tank. Combined with the high thermal conductivity of the aluminum alloy material, the restraint box can quickly reach the preset temperature, solving the problem of slow temperature regulation in traditional devices. At the same time, the transparent cover reduces heat exchange between the box and the outside, and the insulation material on the outside of the restraint box further maintains the internal temperature stability, ensuring long-lasting temperature control.
[0022] 6. This invention utilizes a drive component to rotate the cylindrical shell to achieve massage, while simultaneously driving the air supply unit through bevel gear transmission, enabling temperature control, massage, and ventilation functions to work in tandem: massage promotes blood circulation and accelerates the arm's perception and absorption of temperature, while ventilation further amplifies the temperature control effect, forming a linkage mechanism of "massage-temperature control-ventilation", comprehensively improving the safety and comfort of the infusion process.

Detailed Implementation
[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0038] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0039] like Figures 1-4 As shown, the present invention provides a medical restraint protection device, including a restraint box 1 and a shaking mechanism 2. The shaking mechanism 2 is disposed inside the restraint box 1 and includes a drive component 21, an air chamber 22 and a water chamber 23. The water chamber 23 is fixedly disposed on the left and right sides of the air chamber 22. Slide rails 3 are fixedly disposed on the inner walls of the left and right sides of the restraint box 1. The bottom of the water chamber 23 is provided with a sliding groove 4 that slides with the slide rails 3. The drive component 21 is disposed at the bottom of the restraint box 1 and is connected to the bottom of the air chamber 22.
[0040] like Figures 5-7 As shown, the air chamber 22 has cylindrical shells 24 that are partially exposed to the outside and can rotate. The top of the air chamber 22 has a through-hole for the top of the cylindrical shells 24 to rotate and extend out. Both ends of the cylindrical shells 24 are connected to water inlet pipes 25. The other end of the water inlet pipes 25 passes through the inner walls of the air chamber 22 and the water chamber 23 in sequence through a sealed bearing and extends into the water chamber 23. The top of the air chamber 22 has ventilation holes 26.
[0041] Working principle: By fixing the restraint box 1 to the armrest of the chair, when the patient is receiving an IV infusion, the hand is placed inside the restraint box 1 to prevent the hand from slipping off the armrest when the patient is fatigued, thus preventing IV infusion accidents. Through the set shaking mechanism 2, the drive component 21 drives the air chamber 22 and water chamber 23 to move back and forth inside the restraint box 1, thereby causing the cylindrical shell 24 to roll on the arm, which can massage the patient's arm, improve blood circulation, and prevent the arm from becoming numb from being in the same position for a long time. At the same time, it can also change the contact position between the cylindrical shell 24 and the arm, so that the arm can receive even rolling pressure from the cylindrical shell 24, improving the heat preservation or cooling effect. Meanwhile, the airflow discharged from the vent 26 can blow evenly on the arm, further improving the heat preservation or cooling effect.
[0042] like Figures 8-12 As shown, the drive assembly 21 includes a motor 212, an eccentric disk 213, a connecting rod 214, a mounting plate 215, and a fixing frame 216. The fixing frame 216 is fixed to the bottom of the constraint box 1 and located below the air chamber 22. The fixing frame 216 is n-shaped, and the mounting plate 215 is U-shaped. The mounting plate 215 is slidably mounted on the fixing frame 216 through its top, and the top of the mounting plate 215 is fixedly connected to the bottom of the air chamber 22. The motor 212 is fixedly mounted on the bottom of the mounting plate 215. The eccentric disk 213 is fixedly mounted on the output shaft of the motor 212 and located below the fixing frame 216. The top of the eccentric disk 213 is provided with an annular groove 217. The top of the connecting rod 214 is fixedly mounted on the fixing frame 216, and the bottom of the connecting rod 214 is slidably engaged with the annular groove 217.
[0043] Working principle: The drive component 21 drives the air chamber 22 to move back and forth, thereby enabling the cylindrical shell 24 on the air chamber 22 to roll at the bottom of the arm, massaging the arm. The U-shaped mounting plate 215 is slidably sleeved on the fixed frame 216. When the motor 212 drives the eccentric disk 213 to rotate, under the limiting constraint of the connecting rod 214, the eccentric disk 213 moves back and forth, thereby driving the motor 212 to move back and forth, and thus driving the mounting plate 215 to slide back and forth on the fixed frame 216. Since the two ends of the mounting plate 215 are fixed to the bottom of the air chamber 22, the mounting plate 215 also drives the air chamber 22 to move back and forth, thereby driving the water tanks 23 on the left and right sides of the air chamber 22 to move back and forth. The bottom of the water tank 23 is supported by the sliding rail 3, making the movement smoother.
[0044] like Figures 8-12 As shown, the drive assembly 21 also includes an air supply unit 211, which is located at the bottom of the air chamber 22 and connected to the motor 212. The air supply unit 211 includes an air supply duct 2111, a rotating shaft 2112, a transmission shaft 2113, fan blades 2114, and a support frame 2115. The top of the air supply duct 2111 is connected to the bottom of the air chamber 22 and communicates with its interior. The support frame 2115 is cross-shaped and fixedly installed inside the air supply duct 2111. The rotating shaft 2112 is rotatably mounted on the support frame 2115 via bearings. 2114 is fixed to the top of the rotating shaft 2112. The bottom of the rotating shaft 2112 is fixed with a bevel gear 2116. The transmission shaft 2113 rotates horizontally through the air supply duct 2111 via a bearing. One end of the transmission shaft 2113 is fixed with a bevel gear 2117. The bevel gear 2116 meshes with the bevel gear 2117. The other end of the transmission shaft 2113 is fixed with a bevel gear 2118. The output shaft of the motor 212 is fixed with a bevel gear 2119. The bevel gear 2118 meshes with the bevel gear 2119.
[0045] When the motor 212 drives the eccentric disk 213 to rotate via the air supply unit 211, it also drives the fan blades 2114 inside the air supply duct 2111 to rotate. The rotation of the fan blades 2114 delivers gas into the air chamber 22. The gas inside the air chamber 22 is discharged through the vent 26 at the top of the air chamber 22, thus blowing air onto the arm at the top of the air chamber 22. Since the cylindrical shell 24 extends slightly beyond the top of the air chamber 22, and the arm is placed on the parallel cylindrical shells 24, the arm... The cylinder shell 24 will not block the vent 26 and will not affect the exhaust of the vent 26. Therefore, when the cylinder shell 24 rolls back and forth at the bottom of the arm, the gas discharged from the vent 26 will continue to blow onto the arm. In addition, the cylinder shell 24 will rotate inside the air chamber 22 and come into contact with the gas inside the air chamber 22. By filling the cylinder shell 24 with hot or cold water, the gas inside the air chamber 22 can be heated or cooled. Thus, the temperature of the gas discharged from the vent 26 can be controlled to achieve the effect of keeping the arm warm or cooling it down.
[0046] like Figures 6-12 As shown, the water inlet pipe 25 is located at one end inside the water tank 23 and has stirring blades 28 distributed on it. When the cylindrical shell 24 rotates, the stirring blades 28 drive the water inlet pipe 25 and the stirring blades 28 to rotate synchronously. The stirring blades 28 stir the water in the water tank 23, so that the heat of the water in the water tank 23 can be quickly dissipated, and the interior of the constraint box 1 can be quickly cooled or heated.
[0047] like Figures 1-2As shown, the top of the restraint box 1 is open, and a transparent cover 5 is hinged to one side of the top. The transparent cover 5 facilitates the infusion of fluids inside the restraint box 1 and reduces the exchange of heat between the restraint box 1 and the outside, so that the temperature inside the restraint box 1 is higher or lower than the outside temperature. The outside of the restraint box 1 is wrapped with heat-insulating material to further reduce the exchange of heat with the outside.
[0048] like Figures 1-2 As shown, the restraint box 1 has a strap 6 on one side and a connecting ring 7 fixed on the other side. When in use, the restraint box 1 is placed on the armrest of the chair, and then the strap 6 is wrapped around the armrest of the chair and tied to the connecting ring 7 to bind the restraint box 1 to the armrest of the chair.
[0049] like Figures 1-2 As shown, the transparent cover plate 5 has an infusion tube receiving groove 8 on one side, and the restraint box 1 has an arm avoidance opening 9 on the front side wall. The infusion tube receiving groove 8 facilitates the infusion tube to pass through the restraint box 1, preventing the transparent cover plate 5 from squeezing the infusion tube. The arm avoidance opening 9 facilitates the placement of the patient's arm in the restraint box 1.
[0050] like Figures 1-2 As shown, a hand placement platform 10 is fixedly provided inside the restraint box 1, and the hand placement platform 10 is located behind the shaking mechanism 2. With the hand placement platform 10, the patient's hand can be placed on the hand placement platform 10 to keep the patient's hand flat, which is convenient for infusion. The infusion tube receiving groove 8 is located above the hand placement platform 10, which is convenient for the extension of the infusion tube out of the restraint box 1.
[0051] like Figures 3-6 As shown, the height of both water tanks 23 is greater than the height of the air tank 22, and the top of the water tank 23 is provided with a water inlet 27. The water tank 23 is provided with a heating element (not shown). The height of the water tank 23 is greater than the height of the air tank 22 in order to surround the arm and allow the temperature inside the water tank 23 to be better diffused to the arm. The heating element can be used to heat the water in the water tank 23. The constraint box 1 is provided with a controller (not shown) on the outside. The controller is electrically connected to the motor 212 and the heating element, and the controller controls the motor 212 and the heating element (this is prior art and will not be described in detail).
[0052] In practical use, the restraint box 1 is tied to the armrest of the seat by the strap 6. Then, the arm receiving the infusion is placed into the restraint box 1, and the patient's arm contacts the part of the cylindrical shell 24 that extends out of the air chamber 22, so that the cylindrical shell 24 supports the patient's arm. At the same time, the patient's hand is placed on the hand placement platform 10, and the hand placement platform 10 is approximately the same as the top of the cylindrical shell 24 as the air cylinder, so as to ensure that the arm and hand are in a flat position. Then, the transparent cover 5 is closed, and the infusion tube is placed into the infusion tube receiving slot 8 to prevent the transparent cover 5 from squeezing the infusion tube and affecting the infusion.
[0053] When it is necessary to keep the patient's arm and hand warm, the water in the water tank 23 is heated by the heating element inside the water tank 23. The water in the water tank 23 is connected to the cylindrical shell 24 through the water inlet pipe 25, and the height of the water tank 23 is greater than the height of the cylindrical shell 24, so the cylindrical shell 24 is also filled with hot water. The cylindrical shell 24 is in contact with the arm, thus keeping the arm warm. At the same time, both the water tank 23 and the cylindrical shell 24 are made of aluminum alloy, which facilitates heat conduction to the restraint box 1, thereby raising the temperature inside the restraint box 1 and keeping the hand warm. Simultaneously, the motor 212 is started, driving the eccentric disk 213 to rotate. Since the connecting rod 214 is fixed on the fixing frame 216, when the eccentric disk 213 rotates, it drives the motor 212 and the mounting plate 215 to move back and forth along the fixing frame 216, thereby driving the air chamber 22 to move back and forth. The movement of the cylindrical shell 24 causes it to roll on the arm, which massages the patient's arm, improves blood circulation, and prevents numbness caused by prolonged periods in the same position. It also changes the contact position between the cylindrical shell 24 and the arm, allowing the arm to receive even rolling pressure from the cylindrical shell 24 and improving the heat preservation effect. At the same time, the motor 212 drives the rotation of the transmission shaft 2113 through the meshing of bevel gear 4 2119 and bevel gear 3 2118. Through the meshing of bevel gear 2 2117 and bevel gear 1 2116, the rotation of the rotating shaft 2112 is driven, which in turn drives the rotation of the fan blade 2114. The fan blade 2114 blows air into the air chamber 22, causing the warm air inside the air chamber 22 to be discharged from the vent 26. This allows the warm air to quickly diffuse into the restraint box 1, causing the interior of the restraint box 1 to heat up rapidly and further improve the heat preservation effect.
[0054] When it is necessary to cool down the patient's arm and hand with a blower, the operation is basically the same. The difference is that when cooling down, cold water is added to the water tank 23, and hot water is not needed. Through the cold zone effect of the cold water, the cylindrical shell 24 comes into contact with the arm, thus cooling the arm. The cold airflow discharged from the vent 26 has a cooling effect, which not only cools down the arm, but also dries the sweat on the arm. At the same time, both the water tank 23 and the cylindrical shell 24 are made of aluminum alloy, which facilitates heat conduction to the restraint box 1, thereby reducing the temperature inside the restraint box 1 and thus cooling the hand. Meanwhile, the cylindrical shell 24 rolls at the bottom of the arm, which can massage the patient's arm, improve blood circulation, prevent the arm from becoming numb from being in the same position for a long time, and also change the contact position between the cylindrical shell 24 and the arm, so that the cooled airflow blows evenly on the arm and avoids blind spots in cooling.
