Description

Technical Field

[0001] This utility model relates to the field of medical rescue technology, specifically a detachable stretcher bed for restraining mental patients. Background Technology

[0002] When a mentally ill patient is uncooperative with treatment and management, or exhibits impulsive or even aggressive behavior, it is necessary to restrain the patient to a bed in the intensive care unit for appropriate treatment.

[0003] However, when a patient suddenly exhibits stressful behavior in the corridor or lobby, staff need to work together to restrain the patient and transfer them to a bed for treatment. Because patients often act uncontrollably and can be aggressive when exhibiting stressful behavior, there is a risk of the patient injuring the staff when staff restrain the patient on the ground and move them towards the bed. Furthermore, the restrained transfer process is inhumane for the patient. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a detachable stretcher bed for restraining mental patients, which aims to reduce the harm suffered by staff during the transfer of mental patients and the inhumane behavior towards patients during the transfer process.

[0005] A detachable stretcher bed for restraining mental patients includes a stretcher and a bed frame. The bed frame is equipped with casters at the bottom, and a mattress is placed on the stretcher. The stretcher is slidably mounted on the bed frame. The bed frame is equipped with a moving mechanism for driving the stretcher to move along the width and height of the bed frame. A support unit is provided at the bottom of the stretcher to provide support for the stretcher after it has slid along the bed frame. Several restraint units are hidden on both sides of the stretcher along its length.

[0006] Preferably, a rotating shaft is rotatably mounted on the bed frame. A spur gear and a first bevel gear are respectively mounted on one end of the rotating shaft along its length, and the spur gear and the first bevel gear can rotate with the rotating shaft. The moving mechanism includes a lateral moving component and a longitudinal moving component. The lateral moving component includes a rack, which is arranged along the width direction of the bed frame. A transmission component is fixedly connected to the stretcher. The transmission component is arranged along the width direction of the stretcher and fixedly connected to the rack along its length direction. The spur gear meshes with the rack to drive the stretcher to move along the width direction of the bed frame. The longitudinal moving component includes a second bevel gear and a screw. The second bevel gear is fixedly connected to the screw. The screw is arranged longitudinally. The first bevel gear and the second bevel gear mesh with each other to drive the screw to rotate. The transmission component is threadedly connected to the screw. The rotation of the screw drives the transmission component to move longitudinally along the screw. A sliding groove is horizontally arranged on the bed frame along its width direction. The bottom of the screw is rotatably mounted in the sliding groove and can slide along the length of the sliding groove.

[0007] Preferably, the bed frame has horizontal crossbars at both ends along its length, the crossbars are perpendicular to the length of the bed frame, and the crossbars have a groove along their length. The support unit includes a support rod and a connecting rod. One end of the connecting rod along its length is fixedly connected to the stretcher, and the other end of the connecting rod away from the stretcher is hinged to the support rod, with a return torsion spring at the hinge. The support rod is rotatably positioned along the length of the groove.

[0008] Preferably, the stretcher includes a frame arranged circumferentially along the bed frame, and several storage cavities are opened on both sides of the frame along its length, and several constraint units are arranged in the storage cavities.

[0009] Preferably, the storage cavity is provided with an installation box, and the constraint unit is disposed inside the installation box. The constraint unit includes an installation rod horizontally disposed inside the installation box, a bushing slidably sleeved on the installation rod, and a constraint strap wrapped around the bushing. The two ends of the installation rod are rotatably disposed inside the installation box along its length. One end of the constraint strap is fixedly connected to the bushing along its length. The constraint strap can be released towards the end away from the bushing. The installation box has an opening on the side facing the bed. The end of the constraint strap away from the bushing passes through the opening and can be stretched towards the mattress. Spring plates are provided at both ends of the installation box along its length. The spring plates are wrapped around the two ends of the installation rod along its length, and the two ends of the spring plates along their length are fixedly connected to the installation rod and the installation box, respectively.

[0010] Preferably, the mounting box includes an end cap and a housing, a pivot pin is provided between the end cap and the housing, a torsion spring is provided on the pivot pin, the two spring arms of the torsion spring are fixedly connected to the housing and the end cap respectively, and the housing has a notch on the side opposite to the spring arms of the torsion spring.

[0011] (1) In this solution, the stretcher is driven to slide along the bed frame by a moving mechanism, so that staff can quickly move the stretcher to a suitable position, such as in the corridor. When a mental patient has an attack, the stretcher is moved to a suitable position by sliding and then the patient is restrained and transported. Hidden restraint units are set on both sides of the stretcher to effectively restrain the patient when needed, while avoiding excessive restriction and discomfort to the patient. The support unit and mattress provide a stable environment when staff use the restraint unit to restrain the patient, reducing accidental injury caused by accidental movement of the stretcher. Restraining the patient by the restraint unit reduces the harm to staff and staff during the patient's attack. At the same time, the detachable stretcher avoids the inhumane behavior of staff carrying the patient to the bed after restraining the patient.

[0012] (2) In this scheme, the patient is restricted by the restraint unit, and the bushing can slide the mounting rod to adapt to patients with different arm lengths; at the same time, the restraint strap is stretched along the opening toward the mattress to facilitate the staff to use the restraint strap to restrain the patient; and the end cap covers the restraint strap, which also reduces the stress behavior that the patient may have after seeing the restraint strap.

[0022] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 8 As will be clearly shown in the detailed description of the embodiments, all structural contents mentioned in the following embodiments are based on the accompanying drawings.

[0023] Example 1: This example provides a detachable stretcher bed for restraining mental patients, such as... Figure 1 and Figure 2As shown, the bed includes a stretcher 1 and a bed frame 2. The bed frame 2 includes four bed legs, which are arranged in parallel and vertical positions. In this embodiment, connecting rods are fixedly installed between each pair of parallel bed legs. The bed legs and connecting rods together form the basic structure of the bed frame 2.

[0024] like Figure 1 As shown, casters 3 are provided at the bottom of the four bed legs. In this embodiment, the casters 3 are all universal brake wheels, which facilitate turning and provide stable support for the stretcher bed by operating the universal brake wheels when reaching the designated position.

[0025] In this embodiment, as Figure 2 As shown, the stretcher 1 includes a frame 16 arranged circumferentially along the bed frame 2 and several support plates fixed laterally along the frame 16. In this embodiment, four support plates are provided; as shown Figure 1 As shown, a mattress 4 is placed on the support plate, and the overall size of the mattress 4 is smaller than the overall size of the frame 16.

[0026] like Figure 2 , Figure 3 and Figure 5 As shown, the stretcher 1 is slidably mounted on the bed frame 2, and a moving mechanism is provided on the bed frame 2. The size of the stretcher 1 in the width direction is larger than that of the bed frame 2. The moving mechanism is used to drive the stretcher 1 to move along the width and height directions of the bed frame 2. A support unit is provided at the bottom of the stretcher 1 to provide support for the stretcher 1 after it moves along the height direction of the bed frame 2. Several restraint units are hidden on both sides of the stretcher 1 in the length direction. In this embodiment, there are a total of eight restraint units, namely four groups of two opposite each other, which are used to restrain the patient's wrists, ankles, waist and abdomen and shoulders respectively. When the patient is subjected to stress and produces stress behavior, the restraint units restrain the patient, thereby reducing the probability of the patient injuring himself and the staff.

[0027] In this embodiment, the moving mechanism can drive the stretcher 1 to slide along the width and height of the bed frame 2. That is, when a patient exhibits stress behavior in a corridor or hall, staff can push the stretcher to the scene. Once the patient reaches the designated position, the position of the stretcher is fixed by the casters 3. The moving mechanism separates the stretcher 1 from the bed frame 2. At this time, the support unit provides support for the stretcher 1. Staff can place the patient on the stretcher 1 and then restrain the patient using the restraint straps 20. The hidden design of the restraint unit can also reduce the patient's psychological resistance.

[0028] Example 2, based on Example 1, is improved in that, as follows: Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a rotating shaft 5 is rotatably installed along the length of the bed frame 2. A mounting platform is fixedly installed on one of the legs of the bed frame 2. One end of the rotating shaft 5 along its length is rotatably placed on the mounting platform. A spur gear 6 and a first bevel gear 7 are fixedly installed at the end of the rotating shaft 5 away from the mounting platform. When the operator rotates the rotating shaft 5, the spur gear 6 and the first bevel gear 7 rotate with the rotating shaft 5.

[0029] like Figure 2 , Figure 3 and Figure 5 As shown, the moving mechanism includes a lateral moving component and a longitudinal moving component. The lateral moving component includes a rack 8 and a transmission component 11 fixedly connected to the rack 8. The rack 8 is horizontally arranged along the width direction of the bed frame 2. The transmission component 11 is L-shaped. The upper end of the vertical part of the transmission component 11 is fixedly connected to the support plate, and the horizontal part of the transmission component 11 is fixedly connected to the rack 8. When the operator rotates the shaft 5, the spur gear 6 meshes with the rack 8, causing the connecting component to move along the width direction of the bed frame 2, thereby driving the stretcher 1 to move along the width direction of the bed frame 2.

[0030] like Figure 2 , Figure 3 and Figure 5 As shown, the longitudinal movement assembly includes a second bevel gear 9 and a screw 10. The second bevel gear 9 and the screw 10 are fixedly connected, and the screw 10 is vertically arranged. The transmission component 11 is threadedly connected to the screw 10. When the first bevel gear 7 and the second bevel gear 9 mesh with each other, the transmission component 11 moves along the height direction of the screw 10, thereby driving the stretcher 1 to slide along the height direction of the bed frame 2.

[0031] like Figure 2 and Figure 3 As shown, in this embodiment, the bed frame 2 has a sliding groove installed laterally on the connecting rod in the length direction. The sliding groove has a seal at both ends. The bottom of the screw 10 can rotate in the sliding groove, and the bottom of the screw 10 can slide along the length direction of the sliding groove. The sliding groove is T-shaped to limit the sliding of the screw. At the same time, the sliding groove serves as a load-bearing element to support the screw.

[0032] In this embodiment, the second bevel gear 9 is disposed on the side opposite to the first bevel gear 7. When the operator rotates the shaft 5, the spur gear 6 meshes with the rack 8. At this time, the transmission component 11, the second bevel gear 9, the screw 10, and the support plate slide along the width direction of the bed frame 2, and the screw 10 slides along the length direction of the slide groove. (Refer to...) Figure 5 As the second bevel gear 9 moves with the transmission component 11, it will eventually mesh with the first bevel gear 7. At this time, the stretcher 1 has been completely moved out from above the bed frame 2. The staff continues to shake the shaft 5. At this time, the first bevel gear 7 and the second bevel gear 9 mesh with each other, thereby driving the stretcher 1 to move along the height direction of the screw 10.

[0033] Example 3, based on Example 2, is improved in that, as follows: Figure 2 , Figure 3 and Figure 5 As shown, a load-bearing platform is threadedly connected to the four bed legs on the side away from the casters 3. A horizontal bar 12 is horizontally arranged between the two load-bearing platforms in the width direction. The bottom of the horizontal bar 12 is fixedly connected to the load-bearing platform, and the horizontal bar 12 is perpendicular to the length direction of the bed frame 2. An embedding groove 13 is provided through the horizontal bar 12 along the length direction of the horizontal bar 12.

[0034] Reference Figure 3 , Figure 4 and Figure 5 The support unit includes a support rod 14 and a connecting rod 15. One end of the connecting rod 15 is fixedly connected to the support plate along its length, and the end of the connecting rod 15 facing away from the support rod 14 is hinged to the support rod 14, so that the support rod 14 can form different angles with the connecting rod 15 through the hinge; see reference. Figure 3 and Figure 4 When the stretcher 1 is not separated from the bed frame 2, the support rod 14 and the connecting rod 15 form a 90-degree angle. At this time, the support rod 14 is placed horizontally in the mounting groove 13; refer to Figure 5 When stretcher 1 is separated from bed frame 2, support rod 14 and connecting rod 15 form an angle of 180 degrees.

[0035] In this embodiment, to improve stability when the support rod 14 and the connecting rod 15 form a 180-degree angle, a return torsion spring is provided at the hinge point of the support rod 14 and the connecting rod 15. When the stretcher 1 and the bed frame 2 are not separated, the support rod 14 is positioned along the length of the mounting groove 13, and the return torsion spring is subjected to pressure from the stretcher 1. At this time, the return torsion spring at the hinge point of the support rod 14 and the connecting rod 15 is torsionped. When the stretcher 1 moves along the length of the bed frame 2 under the action of the lateral movement assembly, the support rod 14 leaves the mounting groove 13, and the return torsion spring causes the support rod 14 and the connecting rod 15 to form a 180-degree angle.

[0036] Example 4, based on Example 3, is improved in that, as follows: Figure 2 and Figure 5 As shown, four storage cavities are provided on both sides of the frame 16 along its length, and the storage cavities correspond to each other in pairs. Each storage cavity is equipped with a constraint unit.

[0037] In this embodiment, by installing the restraint unit inside the storage cavity, the restraint unit is designed to be hidden, thereby reducing the probability that the patient will see the restraint unit and react with stress.

[0038] Example 5, based on Example 4, is improved in that, as follows: Figure 5As shown, an installation box 17 is installed inside the storage cavity, and a constraint unit is installed inside the installation box 17.

[0039] Reference Figure 6 Figure 7 and Figure 8 The constraint unit includes a mounting rod 18 horizontally installed in the mounting box 17, a bushing 19 slidably sleeved on the mounting rod 18, and a constraint strap 20 wrapped around the bushing 19. The two ends of the mounting rod 18 are rotatably installed inside the mounting box 17 in the length direction. The mounting box 17 has an opening 21 on the side facing the mattress 4. The constraint strap 20 can be stretched toward the mattress 4 through the opening 21, and one end of the constraint strap 20 in the length direction is fixedly connected to the bushing 19. In this embodiment, in order to facilitate the stretching of the constraint strap 20 toward the mattress 4, the frame 16 has the same opening 21 at the corresponding opening 21 of the mounting box 17. In order to facilitate the stretching of the constraint strap 20 by the staff, a part of the constraint strap 20 away from the bushing 19 passes through the opening 21 of the mounting box 17 and the frame 16. The end of the constraint strap 20 extending out of the opening 21 is edged so that the extended size is larger than the size of the opening 21, to prevent the extended end of the constraint strap 20 from falling into the mounting box 17 and causing inconvenience to the staff.

[0040] Reference Figure 7 The mounting rod 18 has a groove along its length, and a slider is fixed on the bushing 19. The size of the slider matches the size of the groove, so that the bushing 19 slides along the length of the mounting rod 18.

[0041] Reference Figure 6 , Figure 7 and Figure 8 Mounting box 17 has mounting bases fixedly installed at both ends along its length. Each mounting base includes an upper mounting base and a lower mounting base, which are fixedly connected by screws. A circular hole is formed between the upper and lower mounting bases, and both ends of the mounting rod 18 are positioned within this circular hole and can rotate within it. (Refer to...) Figure 8 A spring sheet 24 is provided in the circular hole. The spring sheet 24 is circumferentially arranged around both ends of the mounting rod 18 along its length direction. Both ends of the spring sheet along its length direction are connected to the mounting rod 18 and the mounting base, respectively. In this embodiment, the end of the spring sheet along its length direction facing the mounting rod 18 is engaged in the groove opened in the mounting rod 18, and the end of the spring sheet along its length direction away from the mounting rod 18 is fixedly connected to the mounting base.

[0042] In this embodiment, in order to reduce the weight of the stretcher 1, the frame 16 is a hollow tube; and the outer width of the mounting box 17 is adapted to the inner width of the frame 16; the restraint strap 20 uses a magnetic buckle restraint strap 20.

[0043] Example 6, as Figure 8As shown, the mounting box 17 includes an end cap 171 and a housing 172. The end cap 171 is positioned above the housing 172 and covers the constraint unit installed inside the mounting box 17. In this embodiment, two metal hinges are fixedly installed on both the end cap 171 and the housing 172, and the circular holes on the metal hinges are on the same straight line. A pivot pin is installed through the circular holes on the metal hinges, so that the end cap 171 can rotate around the pivot pin to open and close the mounting box 17. Two torsion springs 22 are provided on the pivot pin. The two torsion springs 22 are respectively located on both sides of the pivot pin along its length, and the two spring arms of the torsion springs 22 are fixedly connected to the housing 172 and the end cap 171, respectively. The elastic force of the torsion springs 22 reduces the probability of the end cap 171 being opened. In order to facilitate the opening of the end cap 171 by the operator, a notch 23 is provided on the side of the housing 172 that is connected to the spring arm of the torsion spring 22.

[0044] In this embodiment, the metal hinges are fixedly connected to the end cap 171 and the housing 172 by welding; in order to reduce the probability of the pin falling out of the round hole, both ends of the pin are bent; the spring arm of the torsion spring 22 is also fixed to the end cap 171 and the housing 172 by welding.

[0045] In this embodiment, such as Figure 8 As shown, when the restraint strap 20 needs to be replaced after long-term use, the worker opens the end cover 171 from the notch 23, uses a screwdriver to release the fixing between the upper and lower mounting seats, takes out the mounting rod 18 and removes the bushing 19, and then removes the restraint strap 20. After the restraint strap 20 is replaced, the mounting rod 18 is installed between the upper and lower mounting seats and the upper and lower mounting seats are fixed. The end cover 171 seals the restraint unit under the elastic force of the torsion spring 22.

[0046] Working principle: When in use, if staff find a patient suddenly exhibiting stress behavior in the corridor or lobby, they can move the stretcher to the patient and secure it using casters 3. Then, by cranking the pivot 5, the stretcher 1 is driven to slide along the width of the bed frame 2 until the first bevel gear 7 and the second bevel gear 9 begin to mesh. At this point, the support rod 14 opens. Continuing to crank the pivot 5, the stretcher 1 moves along the height of the bed frame 2 until the bottom of the support rod 14 touches the ground. At this point, staff can lift the patient onto the stretcher 1, pull the restraint straps 20 to restrain the patient, and then use a leveling device... The position of the shift sleeve 19 is adjusted to match the position of the restraint strap 20 with the patient's arm length; or when the patient exhibits stress behavior and cannot be lifted onto the stretcher 1 first, the staff stretches the restraint strap 20 to restrain half of the patient. After the restraint of half of the patient is completed, the patient is transferred to the stretcher 1 to restrain the other half. The restraint strap 20 is then adjusted according to the tightness. After the restraint is completed, the staff can lift the stretcher 1 and place it on the bed frame 2. The support rod 14 is then embedded in the mounting groove 13, the casters 3 are released, and the stretcher bed is pushed to the ward for treatment of the patient.

[0047] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
