Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a convenient bedside injection bed. Background Technology
[0002] Currently, most patient beds are individual beds, and caregivers usually sit on the edge of the bed. Medical staff often stand when making rounds or inquiring about patients' conditions. When medical staff need to perform lengthy technical procedures, such as measuring blood pressure, intubation, or drawing blood, their workload increases. Prolonged bending over without a place to sit can easily lead to fatigue and reduced efficiency. Due to the special nature of hospital facilities and the need for hygiene and disinfection in medical care, objects other than beds and essential medical facilities are prohibited in patient rooms. External stools are not allowed in patient rooms. Some hospitals, for special reasons, may provide a stool for each bed in certain wards, but this can easily lead to clutter and unsanitary conditions.
[0003] Some hospitals now install foldable benches at the bottom of hospital beds to avoid the aforementioned situation. However, in actual use, the following problems may arise: 1. Since the folding stool requires medical staff to fold it themselves, and since medical staff usually need to carry syringes, infusion bottles, disinfectant and other injection supplies, it is inconvenient for them to fold the stool with their hands. They need to place the injection supplies on the bedside table or bedside first. When there are many items around, it may tip over. At the same time, the operation is more troublesome and affects the efficiency of injection for patients. 2. Since the bottom of the folding stool is not supported and has limited load-bearing capacity, the connection between the stool and the hospital bed may break when the weight of the medical staff is too large or after long-term use, thus damaging the device and requiring replacement. Utility Model Content
[0004] In order to solve the above problems, the purpose of this utility model is to provide a convenient bedside injection bed, which solves the problem that existing folding stools are prone to breakage due to limited load-bearing capacity and lack of bottom support.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A convenient bedside injection bed includes a bed body, a seat mechanism rotatably disposed below the bed body, and a limiting mechanism extending through one side of the bed body to limit the seat mechanism; the seat mechanism includes a rotating column vertically rotatably disposed below the bed body, a first mounting plate fixed to one side of the rotating column, a seat assembly fixed to the rotating column opposite to the first mounting plate, a second mounting plate fixed below the bed body and located on one side of the first mounting plate, and a first return spring disposed between the first mounting plate and the second mounting plate; the limiting mechanism includes a limiting rod vertically extending through one side of the bed body and whose lower end is used to limit the seat assembly, and a limiting rod fixed to the limiting rod. The bed includes a platform at the top of the rod and inside the bed body, a second return spring located between the platform and the bed body for lifting the platform, and a limiting component located on one side of the bed body to limit the platform from popping upwards above the bed body. The bed body has a platform movable slot on one side of its upper surface, and a limiting rod movable slot communicating with the platform movable slot is located inside the bed body. The platform is movably disposed within the platform movable slot, and the limiting rod is movably disposed within the limiting rod movable slot, extending upwards into the platform movable slot and fixedly connected to the platform. The second return spring is sleeved on the upper outer side of the limiting rod and located between the platform movable slot and the platform.
[0006] More preferably, the bed body has a limiting component movable groove on one side of the movable groove of the platform, which communicates with the movable groove of the platform, and the limiting component is rotatably disposed in the limiting component movable groove; the limiting component includes a rotating shaft fixed vertically in the limiting component movable groove and a limiting component that is horizontally rotatably sleeved on the outside of the rotating shaft and whose movable end can be located above the platform after rotation.
[0007] More preferably, the seat assembly includes a support plate fixed to the rotating column, a seat cushion placed on the support plate, a support frame inserted into the seat cushion after passing through the support plate at the top, and four casters respectively installed at the four corners of the lower part of the support frame.
[0008] More preferably, a magnetic chuck is also fixed on the upper surface of the shelf.
[0009] More preferably, an elastic layer is fixed on the upper surface of the cushion.
[0010] This utility model has the following beneficial effects: 1. In this utility model, by rotating the limiting member away from the top of the shelf, the shelf moves the limiting rod upward under the action of the second return spring to release the limitation on the seat assembly. Then, the first mounting plate and the seat assembly are rotated by the action of the first return spring to realize the rotation of the seat assembly. Finally, the tray containing the injection supplies is placed on the shelf. During this process, the injection supplies are placed on the shelf to avoid the situation where there are many surrounding items and they are easy to tip over when placed on the bedside table or bedside. At the same time, medical staff do not need to fold the stool. This reduces the bending of medical staff as much as possible and improves the efficiency of injection. 2. In this utility model, the cushion mainly bears weight through the support frame and casters placed on the ground, and moves by the combination of the rotating column and support plate, rather than by the force of the hinge with the hospital bed. The load-bearing capacity is improved, which can reduce the occurrence of cushion damage due to excessive weight of medical staff or wear and tear at the hinge due to long-term use, thereby extending the service life of the device. At the same time, in this device, the support frame and the cushion are connected by plug-in, and the cushion and support frame can be separated and removed when necessary, which facilitates the replacement of some components. The removed cushion and support frame can also be installed to form a separate stool for use. 3. In this utility model, the limiting member rotates to limit or release the platform. When medical staff need to use it, they rotate the limiting member away from the platform. At this time, the platform moves upward under the action of the second return spring until it extends out of the limiting member's movable slot. The platform is then located above the bed body for easy placement by medical staff. When medical staff do not need to use it, they push the platform downward to below the limiting rod's movable slot in the limiting member's movable slot. Then, they rotate the limiting member to the top of the platform to limit it, so that the platform is located below the upper surface of the bed body. This minimizes interference between the platform and the patient lying on the bed when it is not in use. At the same time, it minimizes the possibility of the limiting mechanism moving downward or the seat mechanism popping out due to accidental contact with the platform by the patient, family members, or medical staff when the platform is not in use.

Detailed Implementation
[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. A convenient bedside injection bed includes a bed body 1, a seat mechanism 2 rotatably disposed below the bed body 1, and a limiting mechanism 3 penetrating one side of the bed body 1 and used to limit the seat mechanism 2; the seat mechanism 2 includes a rotating column 21 vertically rotatably disposed below the bed body 1, a first mounting plate 22 fixed to one side of the rotating column 21, a seat assembly 23 fixed on the rotating column 21 opposite to the first mounting plate 22, and a seat assembly 23 fixed below the bed body 1 and located on the first mounting plate. The second mounting plate 24 on one side of the first mounting plate 22 and the first return spring 25 disposed between the first mounting plate 22 and the second mounting plate 24; the limiting mechanism 3 includes a limiting rod 31 vertically penetrating one side of the bed body 1 and used at its lower end to limit the seat assembly 23, a platform 32 fixed to the top of the limiting rod 31 and located inside the bed body 1, a second return spring 33 disposed between the platform 32 and the bed body 1 and used to lift the platform 32, and a second return spring 33 disposed on one side of the bed body 1 and used to limit the placement of the seat assembly 23. The platform 32 pops upward to the limiting component 34 above the bed body 1; a platform movable groove 11 is opened on one side of the upper surface of the bed body 1, and a limiting rod movable groove 13 communicating with the platform movable groove 11 is opened inside the bed body 1. The platform 32 is movably disposed in the platform movable groove 11, and the limiting rod 31 is movably disposed in the limiting rod movable groove 13 and extends upward into the platform movable groove 11 and is fixedly connected to the platform 32. The second return spring 33 is sleeved on the limiting rod. The upper outer side of 31 is located between the movable groove 11 of the platform and the platform 32; the bed body 1 has a limiting member movable groove 12 on one side of the movable groove 11 of the platform, which communicates with the movable groove 11 of the platform, and the limiting component 34 is rotatably disposed in the limiting member movable groove 12; the limiting component 34 includes a rotating shaft 341 vertically fixed in the limiting member movable groove 12 and a limiting member 342 horizontally rotatably sleeved on the outside of the rotating shaft 341, and whose movable end can be located above the platform 32 after rotation.
[0014] When using this device, rotate the limiting component 34 until it leaves the upper surface of the platform 32. At this time, under the action of the second return spring 33, the platform 32 drives the limiting rod 31 to move upward above the seat assembly 23, so that the seat assembly 23 is no longer limited by the limiting rod 31. Then, under the action of the first return spring 25, the first mounting plate 22 drives the seat assembly 23 to rotate, so that the seat assembly 23 rotates out from under the hospital bed. Finally, the medical staff can place the tray containing the injection supplies on the platform 32. After use, the medical staff push the seat assembly 23 under the hospital bed body 1. Then, remove the injection supplies and tray from the table 32, and then push the table 32 downwards until the top of the table 32 is below the limit rod movable groove 13. While keeping the table 32 pressed down, rotate the limit component 34 to be above the table 32, and release the pressure on the table 32. At this time, the table 32 is located in the limit component movable groove 12 under the obstruction of the limit component 34, and the limit rod 31 fixed to the bottom of the table 32 extends to one side of the seat component 23 and limits the seat component 23 to prevent the seat component 23 from rotating outside the bed body 1.
[0015] As a possible implementation of this solution, preferably, the seat assembly 23 includes a support plate 231 fixed to the rotating column 21, a seat cushion 232 placed on the support plate 231, a support frame 233 that passes through the support plate 231 and is inserted into the seat cushion 232, and four casters 234 respectively installed at the four corners of the lower part of the support frame 233; the seat cushion 232 mainly bears weight through the support frame 233 and casters 234 placed on the ground, and moves through the combination of the rotating column 21 and the support plate 231, rather than through... By relying solely on the force of its hinge connection with the hospital bed to bear weight, the load-bearing capacity is improved. This reduces the likelihood of damage to the seat cushion 232 due to excessive weight of medical staff or wear and tear at the hinge during long-term use, thereby extending the lifespan of the device. In addition, the support frame 233 and the seat cushion 232 are connected by a plug-in joint. When necessary, the seat cushion 232 and the support frame 233 can be separated and removed to facilitate the replacement of some components. The removed seat cushion 232 and support frame 233 can also be installed to form a separate stool for use.
[0016] As a possible implementation of this solution, preferably, a magnetic suction cup 321 is also fixed on the upper surface of the shelf 32; most of the trays used in hospitals for holding injection supplies are made of metal. When the tray is placed on the shelf 32, the magnetic suction cup 321 can magnetically attract the tray to prevent the tray from slipping off the shelf 32.
[0017] As a possible implementation of this solution, preferably, an elastic layer 2321 is fixed on the upper surface of the cushion 232; the setting of the elastic layer 2321 can increase the comfort of medical staff when using the stool.
[0018] The general usage process of this device is as follows: When an injection is needed, rotate the limiting member 342 until it is away from the upper surface of the stage 32. At this time, as... Figure 6 As shown, under the action of the second return spring 33, the platform 32 moves the limiting rod 31 upward to above the seat assembly 23. At this time, the limiting rod 31 is located above the seat assembly 23 and does not obstruct the seat assembly 23. Then, as shown... Figure 7 As shown, under the action of the first return spring 25, the first mounting plate 22 drives the seat assembly 23 to rotate outward of the bed body 1 through the rotating column 21, so that the seat assembly 23 rotates out from under the bed. Finally, the medical staff can place the tray containing the injection supplies on the shelf 32. After the injection is completed, the medical staff pushes the seat assembly 23 under the bed body 1, then removes the injection supplies and tray from the platform 32, and then pushes the platform 32 downwards until the top of the platform 32 is below the limit rod movable groove 13. While maintaining the downward pressure on the platform 32, the limit assembly 34 is rotated to be above the platform 32. The downward pressure on the platform 32 is released. At this time, the platform 32 is located in the limit member movable groove 12 under the obstruction of the limit assembly 34, and the limit rod 31 fixed to the bottom of the platform 32 extends to one side of the seat assembly 23 and limits the seat assembly 23 to prevent the seat assembly 23 from rotating outside the bed body 1.
