Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a medical restraint protection device. Background Art

[0002] During clinical infusion therapy, the placement and state of the patient's arm have always been important factors affecting the safety and comfort of infusion. At present, in common infusion scenarios, patients usually sit down and place the arm that needs infusion flat on the armrest of the chair to maintain a relatively stable posture for infusion therapy. However, the infusion process often takes a long time, ranging from tens of minutes to several hours. Maintaining the same posture for a long time can easily cause mental fatigue in patients, especially in the recovery stage or in patients with weaker physical conditions, where drowsiness and dozing off are more common. In this state, the patient's arm loses autonomous control and can easily slip off the armrest of the chair inadvertently. The slip of the arm will directly pull the infusion tube being infused, which may cause infusion accidents such as needle displacement, infusion tube detachment, or even blood vessel damage. This not only affects the treatment process, but may also bring additional pain and risks to the patient.

[0003] To address this issue, some infusion assist devices with arm limiting functions have emerged in the prior art. For example, a temperature-controlled, self-restrained psychiatric infusion device disclosed in Chinese Patent Publication No. CN117752900A is a typical example. The design of this device not only supports and limits the patient's hand, preventing the arm from slipping through a restraining structure, but also takes into account the comfort needs during the infusion process. A temperature control function is set up, which can blow cold or hot air according to actual needs to cool or heat the patient's hand, improving the patient's hand feeling during infusion to a certain extent.

[0004] Although such devices have made improvements in positioning and temperature control, they still have obvious limitations in actual application. The core problem is that the patient's arm needs to be placed on the device's massage disc, and the part of the arm that contacts the massage disc is completely covered. This prevents the skin in this area from being exposed to the cold or hot air blown out by the device, making effective temperature regulation impossible. When cooling is required, the contact area is difficult to dissipate heat, and sweat easily accumulates, making the patient feel stuffy and uncomfortable. When heat preservation is required, the area cannot be evenly affected by heat, affecting the overall temperature control effect. This design flaw greatly reduces the device's role in improving patient comfort and fails to fundamentally solve the discomfort caused by arm restraint and uneven temperature control during long-term infusion. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a medical restraint protection device.

[0009] Furthermore, the drive assembly also includes an air supply unit, which is arranged at the bottom of the air bin and connected to the motor. The air supply unit includes an air supply cylinder, a rotating shaft, a transmission shaft, fan blades and a support frame. The top of the air supply cylinder is connected to the bottom of the air bin and communicates with the interior thereof. The support frame is cross-shaped and fixedly arranged in the air supply cylinder. The rotating shaft is rotatably installed in the middle position of the support frame through a bearing. The fan blades are fixed to the top of the rotating shaft. The bottom end of the rotating shaft is fixedly provided with a bevel gear 1. The transmission shaft rotates horizontally through the bearing and passes through the side wall of the air supply cylinder. One end of the transmission shaft is fixedly provided with a bevel gear 2, and the bevel gear 1 is meshed with the bevel gear 2. The other end of the transmission shaft is fixedly provided with a bevel gear 3. The output shaft of the motor is fixedly provided with a bevel gear 4, and the bevel gear 3 is meshed with the bevel gear 4.

[0010] Furthermore, stirring blades are distributed on one end of the water inlet pipe located in the water tank.

[0011] Furthermore, the top of the restraint box is open, and a transparent cover is hingedly provided on one side of the top.

[0012] Furthermore, a strap is provided on one side of the restraint box, and a connecting ring is fixedly provided on the other side of the restraint box.

[0013] Furthermore, an infusion tube accommodating groove is provided on one side of the transparent cover, and an arm avoidance opening is opened on the front side wall of the restraint box.

[0014] Furthermore, a hand placement platform is fixedly provided inside the restraint box, and the hand placement platform is located at the rear side of the shaking mechanism.

[0015] Furthermore, the heights of the two groups of water tanks are greater than the height of the air tank, and a water inlet is provided on the top of the water tank, and a heating plate is provided inside the water tank.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows:

[0017] 1. The present invention uses the overall structural design of the restraint box, which can be firmly fixed on the armrest of the chair with the help of straps and connecting rings. When receiving an infusion, the patient puts his arm into the box and his hand on the hand placement table, and then uses a transparent cover to assist in restraining the patient. This can fundamentally prevent the patient's arm from slipping due to fatigue and drowsiness, and completely solves the infusion accident risks such as infusion tube pulling and needle displacement caused by arm slipping in the background technology, providing reliable safety protection for the infusion process.

[0018] 2. By leveraging the synergistic effects of the motor, eccentric disc, and other components in the drive assembly, this invention drives the air and water reservoirs to reciprocate within the restraint box, thereby causing the cylindrical shell within the air reservoir to roll across the patient's arm. This rolling motion not only simulates a massage action, alleviating muscle stiffness and numbness caused by maintaining the same position for extended periods, but also, by continuously changing the contact point between the cylindrical shell and the arm, evenly distributes force across the arm, preventing poor circulation caused by localized compression. This effectively alleviates the discomfort often associated with immobilizing the arm in conventional devices.

[0019] 3. The present invention heats the water body through the heating plate or directly injects cold water, and the heat or cold is quickly transferred to the arm through the water tank and cylindrical shell made of aluminum alloy; at the same time, the rolling of the cylindrical shell enables all parts of the arm to evenly contact the temperature control source, solving the defect of uneven temperature control of the contact parts of the traditional device in the background technology.

[0020] 4. The present invention utilizes the air vents on the top of the air chamber so that they will not be blocked by the rolling cylindrical shell or the arm. The air supply unit cooperates with the air supply unit to continuously deliver air flow into the air chamber, so that the air flow can blow evenly over the surface of the arm, especially the contact area covered in the traditional device. It can quickly dry sweat when cooling and accelerate heat diffusion when keeping warm, significantly improving the temperature control efficiency and the patient's comfort experience.

[0021] 5. The present invention utilizes the stirring blades on the water inlet pipe to rotate synchronously with the rotation of the cylindrical shell, which can quickly stir the water in the water tank, so that the temperature of hot or cold water is quickly and evenly diffused in the water tank. Combined with the efficient thermal conductivity of the aluminum alloy material, the preset temperature can be quickly reached in the restraint box, solving the problem of slow temperature regulation in traditional devices; at the same time, the transparent cover reduces the heat exchange between the box and the outside world, and the thermal insulation material on the outside of the restraint box further maintains the internal temperature stable, ensuring a long-lasting temperature control effect.

[0022] 6. The present invention utilizes a driving assembly to drive the cylindrical shell to roll to achieve massage, and simultaneously drives the air supply unit through bevel gear transmission, so that the temperature control, massage, and ventilation functions are carried out in coordination: while massage promotes blood circulation, it accelerates the arm's perception and absorption of temperature, and ventilation further amplifies the temperature control effect, forming a "massage-temperature control-ventilation" linkage mechanism, which comprehensively improves the safety and comfort of the infusion process.

DETAILED DESCRIPTION

[0037] 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, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0039] like Figures 1-4 As shown, the present invention provides a medical restraint protection device, comprising a restraint box 1 and a shaking mechanism 2. The shaking mechanism 2 is arranged in the restraint box 1. The shaking mechanism 2 comprises a driving assembly 21, an air tank 22 and a water tank 23. The water tank 23 is fixedly arranged on the left and right sides of the air tank 22. Slide rails 3 are fixedly arranged on the inner walls on the left and right sides of the restraint box 1. A slide groove 4 that slides with the slide rail 3 is provided at the bottom of the water tank 23. The driving assembly 21 is arranged at the bottom of the restraint box 1 and is connected to the bottom of the air tank 22.

[0040] like Figure 5-Figure 7 As shown, cylindrical shells 24 partially exposed to the outside and rotatable are distributed at intervals in the air bin 22. A through hole is opened on the top of the air bin 22 for the top of the cylindrical shell 24 to rotate and extend out. Water inlet pipes 25 are connected to both ends of the cylindrical shell 24. The other end of the water inlet pipe 25 rotates through the inner walls of the air bin 22 and the water bin 23 through a sealed bearing in turn and then extends into the water bin 23. Air holes 26 are distributed on the top of the air bin 22.

[0041] Working principle: By fixing the restraint box 1 on the armrest of the chair, when the patient is receiving an infusion, the patient puts his hand into the restraint box 1 to prevent the patient's hand from slipping from the armrest of the chair when he is tired, causing an infusion accident; through the provided shaking mechanism 2, the driving component 21 is used to drive the air tank 22 and the water tank 23 to move back and forth in the restraint box 1, and then drive the cylindrical shell 24 to roll on the arm, which can massage the patient's arm, improve blood circulation and avoid numbness of the arm due to being in the same posture for a long time. At the same time, it can also change the contact position of the cylindrical shell 24 and the arm, so that the arm can be evenly rolled by the cylindrical shell 24, thereby improving the heat preservation or cooling effect. At the same time, the air flow discharged from the air vent 26 can be evenly blown onto 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 is 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 fixed to the bottom of the mounting plate 215, the eccentric disk 213 is fixed on the output shaft of the motor 212, and is located below the fixing frame 216. An annular groove 217 is provided on the top of the eccentric disk 213, and the top of the connecting rod 214 is fixed on the fixing frame 216, and the bottom end of the connecting rod 214 slides in cooperation with the annular groove 217.

[0043] Working principle: Through the set driving component 21, the air tank 22 is driven to move back and forth, and the cylindrical shell 24 on the air tank 22 is rolled at the bottom of the arm to massage the arm. The U-shaped mounting plate 215 is slidably sleeved on the fixing frame 216. When the motor 212 drives the eccentric disk 213 to rotate, under the limit constraint of the connecting rod 214, the eccentric disk 213 is moved back and forth, and the motor 212 is driven to move back and forth, and the mounting plate 215 is driven to slide back and forth on the fixing frame 216. Since the two ends of the mounting plate 215 are fixedly connected to the bottom of the air tank 22, the mounting plate 215 will also drive the air tank 22 to move back and forth, and then drive the water tanks 23 on the left and right sides of the air tank 22 to move back and forth. The bottom of the water tank 23 is supported by the sliding rail 3 to make the movement smoother.

[0044] like Figures 8-12 As shown, the driving assembly 21 also includes an air supply unit 211, which is arranged at the bottom of the air bin 22 and is connected to the motor 212. The air supply unit 211 includes an air supply cylinder 2111, a rotating shaft 2112, a transmission shaft 2113, fan blades 2114 and a support frame 2115. The top of the air supply cylinder 2111 is connected to the bottom of the air bin 22 and is connected to the interior thereof. The support frame 2115 is cross-shaped and fixedly arranged in the air supply cylinder 2111. The rotating shaft 2112 is rotatably mounted on the support frame 2115 through a bearing. The fan blades 2114 is fixed to the top of the rotating shaft 2112, and a bevel gear 1 2116 is fixed to the bottom of the rotating shaft 2112. The transmission shaft 2113 rotates horizontally through the bearing and passes through the air supply tube 2111. One end of the transmission shaft 2113 is fixed with a bevel gear 2117, and the bevel gear 1 2116 is meshed with the bevel gear 2 2117. The other end of the transmission shaft 2113 is fixed with a bevel gear 3 2118. A bevel gear 4 2119 is fixed on the output shaft of the motor 212, and the bevel gear 3 2118 is meshed with the bevel gear 4 2119.

[0045] By setting the air supply unit 211, when the motor 212 drives the eccentric disk 213 to rotate, it also drives the fan blades 2114 in the air supply cylinder 2111 to rotate, and the rotation of the fan blades 2114 is used to transport gas into the air chamber 22. The gas in the air chamber 22 is discharged through the air vents 26 at the top of the air chamber 22, so that the arm at the top of the air chamber 22 can be blown. Since the cylindrical shell 24 extends out of a part of the top of the air chamber 22, the arm is placed on the cylindrical shell 24 distributed side by side, so the arm It will not press on the air vent 26 and will not affect the exhaust of the air vent 26. Therefore, when the cylindrical shell 24 rolls back and forth at the bottom of the arm, the gas exhausted from the air vent 26 will continue to blow onto the arm. In addition, the cylindrical shell 24 will rotate in the air chamber 22 and come into contact with the gas in the air chamber 22. By filling the cylindrical shell 24 with hot water or cold water, the gas in the air chamber 22 can be heated or cooled, thereby controlling the temperature of the gas exhausted from the air vent 26 to achieve the effect of keeping the arm warm or cooling it.

[0046] like Figure 6-Figure 12 As shown, a stirring blade 28 is distributed on one end of the water inlet pipe 25 located in the water tank 23. Through the provided stirring blade 28, when the cylindrical shell 24 rotates, the water inlet pipe 25 and the stirring blade 28 are driven to rotate synchronously. The stirring blade 28 stirs the water in the water tank 23, so that the heat of the water in the water tank 23 is quickly diffused, and the interior of the restraint box 1 is quickly cooled or heated.

[0047] like Figure 1-Figure 2As shown, the top of the restraint box 1 is open, and a transparent cover 5 is hingedly provided on one side of the top. The transparent cover 5 is provided to facilitate the infusion of the restraint box 1, and can reduce the exchange of heat inside the restraint box 1 with the outside world, so that the temperature inside the restraint box 1 remains higher or lower than the outside temperature. The outside of the restraint box 1 is wrapped with a heat-insulating material to further reduce the exchange of heat with the outside world.

[0048] like Figure 1-Figure 2 As shown, a strap 6 is provided on one side of the restraint box 1, and a connecting ring 7 is fixedly provided on the other side of the restraint box 1. When in use, the restraint box 1 is placed on the armrest of the chair, and then the strap 6 is passed around the armrest of the chair and tied to the connecting ring 7 to tie the restraint box 1 to the armrest of the chair.

[0049] like Figure 1-Figure 2 As shown, an infusion tube receiving groove 8 is provided on one side of the transparent cover 5, and an arm avoidance opening 9 is opened on the front side wall of the restraint box 1. The infusion tube receiving groove 8 is provided to facilitate the infusion tube to pass through the inside of the restraint box 1, preventing the transparent cover 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 Figure 1-Figure 2 As shown, a hand placement table 10 is fixedly provided inside the restraint box 1, and the hand placement table 10 is located on the rear side of the shaking mechanism 2. Through the provision of the hand placement table 10, the patient's hand can be placed on the hand placement table 10 to keep the patient's hand square, which is convenient for infusion, and the infusion tube receiving groove 8 is located above the hand placement table 10, which is convenient for the infusion tube to extend out of the restraint box 1.

[0051] like Figure 3-Figure 6 As shown, the height of the two groups of water tanks 23 is greater than the height of the air tank 22, and a water inlet 27 is provided on the top of the water tank 23, and a heating plate (not shown) is provided inside the water tank 23. The height of the water tank 23 is greater than the height of the air tank 22 in order to surround the arm so that the temperature in the water tank 23 can be better diffused to the arm; the heating plate can be used to heat the water in the water tank 23, and a controller (not shown) is provided on the outside of the restraint box 1. The controller electrically connects the motor 212 and the heating plate, and the controller controls the motor 212 and the heating plate (this is a prior art and will not be repeated).

[0052] During specific use, the restraint box 1 is tied to the armrest of the chair by the strap 6, and then the arm during infusion is placed in the restraint box 1, and the patient's arm contacts the part of the cylindrical shell 24 extending 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 table 10, and the hand placement table 10 and the top of the cylindrical shell 24 are roughly aligned with each other, so as to ensure that the arm and hand are in a flat state. Then, the transparent cover 5 is covered, and the infusion tube is placed in the infusion tube receiving groove 8 to prevent the transparent cover 5 from squeezing the infusion tube and affecting the infusion of the infusion tube;

[0053] When the patient's arms and hands need to be kept warm, the water in the water tank 23 is heated by the heating plate in the water tank 23, and 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, and the cylindrical shell 24 is in contact with the arm, so the arm can be kept warm. At the same time, the water tank 23 and the cylindrical shell 24 are both made of aluminum alloy, which facilitates heat conduction to the restraint box 1, thereby increasing the temperature in the restraint box 1, and thus keeping the hand warm; at the same time, start the motor 212 to drive 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 will drive the motor 212 and the mounting plate 215 to move back and forth along the fixing frame 216, thereby driving the gas tank 22 to move back and forth. The movement of the cylindrical shell 24 drives the cylindrical shell 24 to roll on the arm, which can massage the patient's arm, improve blood circulation and prevent the arm from being numb due to being in the same posture for a long time. At the same time, it can also change the contact position of the cylindrical shell 24 with the arm, so that the arm can be evenly rolled by the cylindrical shell 24, thereby improving the heat preservation effect; at the same time, the motor 212 drives the meshing of the bevel gear four 2119 and the bevel gear three 2118 to drive the rotation of the transmission shaft 2113, and drives the rotation of the rotating shaft 2112 through the meshing of the bevel gear two 2117 and the bevel gear one 2116, thereby driving the rotation of the fan blades 2114, and the fan blades 2114 blow air into the air chamber 22, so that the warm air in the air chamber 22 is discharged from the air vents 26, so that the warm air quickly diffuses in the constraint box 1, so that the interior of the constraint box 1 is quickly heated, further improving the heat preservation effect;

[0054] When it is necessary to blow air to cool the patient's arms and hands, the operation is basically the same. The difference is that when cooling, cold water is added to the water tank 23, and no hot water is needed. Through the cold zone effect of the cold water, the cylindrical shell 24 contacts the arm, so the arm can be cooled. The cold air flow discharged from the air vent 26 has a cooling effect. While cooling the arm, it can also dry the sweat on the arm. At the same time, the water tank 23 and the cylindrical shell 24 are both made of aluminum alloy, which facilitates heat conduction to the restraint box 1, thereby reducing the temperature in the restraint box 1, and then cooling the hand; at the same time, the cylindrical shell 24 rolls at the bottom of the arm, which can massage the patient's arm, improve blood circulation and avoid numbness of the arm from being in the same posture for a long time. At the same time, it can also change the contact position of the cylindrical shell 24 with the arm, so that the cooled air flow is evenly blown on the arm, avoiding the existence of a cooling and blowing blind spot on the arm.
