Description

Technical Field

[0001] The utility model relates to a medical instrument, in particular to a body position limiting device. Background Art

[0002] For patients who have completed knee replacement surgery, it is necessary to restrict the affected limb after surgery. Generally, patients are required to sleep in the supine position or the side-lying position. When adopting the above two sleeping positions, the affected limb needs to be raised and restricted accordingly.

[0003] Most of the existing technologies use pillows to elevate the affected limb. Although the pillow can elevate the affected limb, due to the different thicknesses of the pillows, it is difficult for the patient to control the lifting height of the affected limb, which affects the rehabilitation effect. The restriction of sleeping posture mainly depends on the patient's self-control consciousness. However, the patient often turns over unconsciously in his sleep, and changing the sleeping posture is likely to cause compression on the affected limb, thereby affecting postoperative rehabilitation. Therefore, there is an urgent need for a device that can better restrict the patient's legs. Utility Model Content

[0004] The utility model aims to provide a body position limiting device to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The solution of the utility model to solve the technical problem is:

[0006] A body position limiting device comprises: a bottom plate; a limiting assembly, comprising a base plate, a first limiting plate and a supporting plate, wherein the base plate is arranged on the base plate, two first limiting plates are arranged on the base plate at intervals along the left and right directions, the two first limiting plates can approach or move away from each other, a limiting space is formed between the two first limiting plates, the supporting plate is located in front of the base plate, and the supporting plate can move up and down and be positioned along the upper edge of the base plate.

[0007] This technical solution has at least the following beneficial effects: the patient lies on the bottom plate, places the affected limb between the two first limiting plates, moves the two first limiting plates closer to or farther away from each other, adjusts the size of the limiting space, and thus limits the position of both sides of the thigh, and then places the foot on the support plate. At this time, the support plate can be adjusted up and down to adjust the height of the lifted affected limb. After completion, the support plate is positioned to keep the affected limb lifted. In this way, the support plate can be used to flexibly lift the affected limb to an appropriate height, and the two first limiting plates are used to limit both sides of the affected limb, effectively reducing the risk of injury to the affected limb due to involuntary movements of the patient, better maintaining the positioning of the affected limb, and improving the effect of assisting the patient's rehabilitation, with strong practicality.

[0008] As a further improvement of the above technical solution, the bottom plate is provided with a sliding section extending in the left-right direction and a limiting section connected to both ends of the sliding section, and the two limiting sections are respectively provided with limiting holes penetrating in the left-right direction, and the rear side of the substrate is slidably connected to the sliding section, and the left and right sides of the substrate respectively pass through the two limiting holes, and the limiting section is penetrated with a stopper, and the stopper can limit or release the sliding of the substrate. According to the different body shapes of the patients, or according to the different lying postures of the patients, such as supine position or lateral position, the position of the substrate can be adjusted left and right. Specifically, the sliding section and the two limiting sections can form a frame for sliding and limiting the substrate. When the substrate needs to be adjusted left and right, the sliding restriction of the substrate by the stopper is first released. At this time, the substrate can be adjusted left and right. The substrate is inserted into the two limiting holes on both sides to achieve sliding restriction. After the adjustment is completed, the stopper is locked to the substrate again to limit the left and right movement of the substrate, so as to achieve the position adjustment of the limiting space and the support plate.

[0009] As a further improvement of the above technical solution, a plurality of stop holes are arranged on the substrate in the left-right direction, and a spring is sleeved on the outside of the stopper, and the spring has a tendency to pull the bottom end of the stopper toward the stopper hole. When it is necessary to move the substrate, the stopper is pulled away from the substrate so that the bottom end of the stopper escapes from the stopper hole, and the spring is elastically deformed at this time. After the substrate is adjusted, the pulling force on the substrate is removed, and the stopper is pulled toward the substrate by the spring so that the bottom end of the stopper is inserted into a stopper hole facing the substrate, thereby better realizing the stopper restriction of the substrate.

[0010] As a further improvement of the above technical solution, a screw is rotatably connected to the base plate, the support plate is threadedly connected to the screw, a limit rod is provided on the base plate beside the screw, and the support plate is slidably connected to the limit rod. When the height of the support plate needs to be adjusted, the screw is rotated, and since there is a sliding connection limit between the support plate and the limit rod, the support plate can be adjusted up and down with the forward or reverse rotation of the screw, thereby changing the height of the affected limb.

[0011] As a further improvement of the above technical solution, the limit rod is provided with a scale in the up and down direction. When the support plate moves up and down along the limit rod, the height position of the support plate can be visually checked through the scale, and the height of the patient's affected limb can be accurately judged, which is more conducive to the rehabilitation of the affected limb.

[0012] As a further improvement of the above technical solution, the base plate is provided with a first slide groove extending in the left-right direction, a first adjustment rod is rotatably connected in the first slide groove, the first adjustment rod is provided with two first thread segments with opposite spiral directions, the bottom sides of the two first limit plates are respectively slidably connected to the first slide groove, and the two first limit plates are respectively threadedly connected to the two first thread segments. When the size of the limit space needs to be adjusted, the first adjustment rod can be rotated, because the two first limit plates respectively cooperate with the two first thread segments with different spiral directions, and the two first limit plates are respectively slidably connected to the first slide groove, with the forward or reverse rotation of the first adjustment rod, the two first limit plates can be driven to move closer or farther from each other, thereby completing the adjustment of the size of the limit space.

[0013] As a further improvement of the above technical solution, two second limiting plates are arranged on the bottom plate behind the first limiting plate, and the two second limiting plates can be moved closer to or farther from each other. Two second limiting plates are also arranged on the bottom plate to limit the position of the patient's chest cavity. When the patient lies on the bottom plate, the two second limiting plates can be adjusted to move closer to or farther from each other to adapt to the body shapes of different patients. In this way, the patient's posture can be better limited, which is conducive to reducing the situation where the patient changes his posture unconsciously.

[0014] As a further improvement of the above technical solution, the bottom plate is provided with a second slide groove extending in the left-right direction, a second adjustment rod is rotatably connected in the second slide groove, the second adjustment rod is provided with two second thread segments with opposite spiral directions, the bottom sides of the two second limit plates are respectively slidably connected to the second slide groove, and the two second limit plates are respectively threadedly connected to the two second thread segments. When the position of the second limit plate needs to be adjusted, the second adjustment rod is rotated, and since the two second limit plates respectively cooperate with the two second thread segments with different spiral directions, and the two second limit plates are respectively slidably connected to the second slide groove, the two second limit plates can be driven to move closer or farther from each other with the forward or reverse rotation of the second adjustment rod, so as to complete the adjustment of the space size between the two second limit plates.

[0015] As a further improvement of the above technical solution, the support plate is provided with an arc groove, which extends backward to the rear side of the support plate. When the patient places the foot in the arc groove, the arc groove can better limit the patient's foot, reduce the risk of the affected limb slipping off the support plate, and better maintain the effect of limiting the patient's position.

[0016] As a further improvement of the above technical solution, an elastic pad is connected to the top side of the support plate, which can improve the comfort of foot support and enhance the user experience of the patient. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Reference Figure 1 and Figure 2 A body position limiting device includes a base plate 100 and a limiting assembly, wherein the limiting assembly includes a base plate 210, a first limiting plate 220 and a supporting plate 230, the base plate 210 is arranged on the base plate 100, two first limiting plates 220 are arranged on the base plate 210 at intervals along the left and right directions, the two first limiting plates 220 can be close to or away from each other, and a limiting space is formed between the two first limiting plates 220, the supporting plate 230 is located in front of the base plate 210, and the supporting plate 230 can move up and down along the base plate 210 and be positioned.

[0027] From the above, it can be seen that the patient lies on the base plate 100, places the affected limb between the two first limiting plates 220, moves the two first limiting plates 220 closer to or farther away from each other, adjusts the size of the limiting space, and thus limits the position of both sides of the thigh, and then places the foot on the support plate 230. At this time, the support plate 230 can be adjusted up and down to adjust the height of the affected limb. After completion, the support plate 230 is positioned to keep the affected limb lifted. In this way, the support plate 230 can be used to flexibly lift the affected limb to a suitable height, and the two first limiting plates 220 are used to limit both sides of the affected limb, effectively reducing the risk of the patient's involuntary movement causing injury to the affected limb, better maintaining the positioning of the affected limb, and improving the effect of assisting the patient's rehabilitation, which is highly practical.

[0028] The base plate 210 can be directly slidably connected to the top side of the bottom plate 100. When the position of the base plate 210 needs to be adjusted, the base plate 210 can be directly slid left and right on the bottom plate 100. In the present embodiment, the bottom plate 100 is provided with a sliding section 110 extending in the left and right directions and a limiting section 120 connected to both ends of the sliding section 110. Both limiting sections 120 extend forward. The two limiting sections 120 are respectively provided with limiting holes penetrating in the left and right directions. The two limiting holes extend along the length directions of the two limiting sections 120 respectively. The rear side of the base plate 210 is slidably connected to the sliding section 110. The two can be slidably connected by setting a slider and a slide groove to cooperate with each other. The left and right sides of the base plate 210 pass through the two limiting holes respectively. The limiting section 120 is provided with a stopper 130, and the stopper 130 can limit or release the sliding of the base plate 210. The position of the substrate 210 can be adjusted left and right according to the different body shapes of the patients, or according to the different lying postures of the patients, such as supine position or lateral position. Specifically, the sliding section 110 and the two limiting sections 120 can form a frame for sliding and limiting the substrate 210. When the substrate 210 needs to be adjusted left and right, the sliding restriction of the substrate 210 by the stopper 130 is first released. At this time, the substrate 210 can be adjusted left and right. The substrate 210 is inserted into two limiting holes on both sides to achieve sliding restriction. After the adjustment is completed, the stopper 130 is locked to the substrate 210 again to limit the left and right movement of the substrate 210, thereby realizing the position adjustment of the limiting space and the support plate 230.

[0029] The stopper 130 should be selected to limit the movement of the base plate 210 according to the needs of use, and its structural forms are various. For example, the stopper 130 uses a bolt, and the bolt is threadedly connected to the limiting section 120. When it is necessary to limit the movement of the base plate 210, the end of the bolt is pressed against the base plate 210 to tighten and fix the base plate 210. In the present embodiment, a plurality of stop holes 211 are provided on the base plate 210 along the left and right directions, and a spring 140 is sleeved on the outer side of the stopper 130. The spring 140 has a tendency to pull the bottom end of the stopper 130 toward the stop hole 211. In actual application, the stopper 130 is a rod-shaped structure, and a head with a larger outer diameter is provided at the top end of the stopper 130. The spring 140 is sleeved on the outside thereof. At this time, the top end of the spring 140 is connected to the head, and the bottom end of the spring 140 is connected to the top side of the limiting section 120. When it is necessary to move the substrate 210, the stopper 130 is pulled away from the substrate 210 so that the bottom end of the stopper 130 escapes from the stopper hole 211. At this time, the spring 140 is elastically deformed. After the adjustment of the substrate 210 is completed, the pulling force on the substrate 210 is removed, and the stopper 130 is pulled toward the substrate 210 by the spring 140, so that the bottom end of the stopper 130 is inserted into a stopper hole 211 opposite to it, thereby better realizing the stopping restriction of the substrate 210.

[0030] like Figure 3 As shown, as a specific implementation of the up-and-down rotation adjustment of the support plate 230, the base plate 210 is rotatably connected with a screw rod 240, the support plate 230 is threadedly connected to the screw rod 240, and a limit rod 250 is provided at a position beside the screw rod 240 on the base plate 210, and the support plate 230 is slidably connected to the limit rod 250. When the height of the support plate 230 needs to be adjusted, the screw rod 240 is rotated. Since there is a sliding connection limit between the support plate 230 and the limit rod 250, the up-and-down movement adjustment of the support plate 230 can be achieved with the forward or reverse rotation of the screw rod 240, thereby changing the height of the affected limb lifting. In practical applications, a first knob can be connected to the top of the screw rod 240, and when the screw rod 240 needs to be rotated, the first knob can be used to rotate, which is convenient for applying force and improving the convenience of use.

[0031] In order to better quantify the height of the lifting of the support plate 230, in this embodiment, a scale is set in the up and down direction on the limit rod 250. When the support plate 230 moves up and down along the limit rod 250, the height position of the support plate 230 can be visually checked through the scale, and the height of the patient's affected limb can be accurately judged, which is more conducive to the rehabilitation of the affected limb.

[0032] There are many ways to adjust and position the two first limit plates 220 for left and right movement. For example, two screw rods are respectively provided on the bottom plate 100, and the two first limit plates 220 are respectively connected to the two screw rods. The two screw rods are respectively used as driving sources to drive the two first limit plates 220 to move independently, thereby realizing independent adjustment of the two first limit plates 220. In order to simplify the structure, a driving source can also be directly provided to drive the two first limit plates 220 to move closer or farther away at the same time. Specifically, the base plate 210 is provided with a first slide groove 260 extending in the left and right direction, and the first slide groove 260 is rotatably connected to the first adjustment rod 270. The first adjustment rod 270 Two first thread segments with opposite spiral directions are provided, and the bottom sides of the two first limit plates 220 are respectively slidably connected to the first slide groove 260, and the two first limit plates 220 are respectively threadedly connected to the two first thread segments. In actual applications, the bottom sides of the two first limit plates 220 respectively have protruding parts extending into the first slide groove 260, which are used to slide with the first slide groove 260 and realize threaded connection with the first thread segment. In addition, one end of the first adjusting rod 270 can pass through one side of the substrate 210, and a second knob is connected to the end passing through the substrate 210. When the first adjusting rod 270 needs to be rotated, force can be applied to the second knob to improve the convenience and efficiency of operation.

[0033] When the size of the limiting space needs to be adjusted, the first adjusting rod 270 can be rotated. Since the two first limiting plates 220 respectively cooperate with the two first thread segments with different spiral directions, and the two first limiting plates 220 are respectively slidably connected to the first slide groove 260, as the first adjusting rod 270 is rotated forward or reversed, the two first limiting plates 220 can be driven closer to or farther away from each other, thereby completing the adjustment of the size of the limiting space.

[0034] In the above embodiment, it is mainly used to limit the position of the patient's affected limb, and in order to better limit the patient's posture, the patient's torso can also be limited, for example, the patient's chest can be limited. Specifically, two second limiting plates 310 are provided on the bottom plate 100 behind the first limiting plate 220, and the two second limiting plates 310 can be close to or away from each other. The bottom plate 100 is also provided with two second limiting plates 310 that can limit the position of the patient's chest. When the patient lies on the bottom plate 100, the two second limiting plates 310 can be adjusted to be close to or away from each other to adapt to the body shape of different patients. In this way, the patient's posture can be better limited, which is conducive to reducing the situation where the patient changes his posture unconsciously.

[0035] There are many ways to adjust and position the two second limit plates 310 to the left and right. Similarly, two screw rods are respectively provided on the base plate 100, and the two second limit plates 310 are respectively connected to the two screw rods. The two screw rods are respectively used as driving sources to drive the two second limit plates 310 to move independently, thereby realizing independent adjustment of the two second limit plates 310. In order to simplify the structure, a driving source can also be directly provided, and the two second limit plates 310 can be driven by one driving source to move closer or farther away at the same time. Specifically, a second sliding groove extending in the left and right directions is provided on the base plate 100, and a second adjusting rod 320 is rotatably connected in the second sliding groove. The second adjusting rod 320 is provided with two second threaded sections with opposite spiral directions. The two second limit plates 310 The bottom sides of the plates 310 are respectively slidably connected to the second slide grooves, and the two second limit plates 310 are respectively threadedly connected to the two second threaded segments. In actual applications, the bottom sides of the two second limit plates 310 are provided with two downwardly protruding structures. Similarly, the two protruding structures respectively extend into the second slide grooves, and the two protruding structures are used to slide with the second slide grooves, and the two protruding structures are respectively threadedly connected to the second threaded segments. In order to facilitate the rotation and adjustment of the second adjusting rod 320, one end of the second adjusting rod 320 can be passed through one side of the bottom plate 100, and a third knob is connected to the end of the second adjusting rod 320 passing through the bottom plate 100. When the second adjusting rod 320 needs to be rotated, force can be applied to the third knob to rotate it, thereby improving the convenience of operation.

[0036] In this embodiment, specifically, when the position of the second limit plate 310 needs to be adjusted, the second adjusting rod 320 is rotated. Since the two second limit plates 310 respectively cooperate with the two second thread segments with different spiral directions, and the two second limit plates 310 are respectively slidably connected to the second slide grooves, as the second adjusting rod 320 is rotated forward or reversed, the two second limit plates 310 can be driven to move closer to or away from each other, thereby completing the adjustment of the space size between the two second limit plates 310.

[0037] The top surface of the support plate 230 can be a plane. When the patient's foot is placed on the support plate 230, the foot is easy to slide and fall from the top side of the support plate 230. In order to better limit the position of the patient's foot, in this embodiment, an arc groove is provided on the support plate 230. The arc groove is a groove structure in the shape of an arc, and the arc opening of the arc groove is arranged upward, and the arc groove extends backward to the rear side of the support plate 230. When the patient places the foot on the arc groove, the arc groove can be used to better limit the patient's foot, reduce the risk of the affected limb sliding and falling from the support plate 230, and better maintain the effect of limiting the patient's position.

[0038] Furthermore, an elastic pad is connected to the top side of the support plate 230. The elastic pad can improve the comfort of the foot support and enhance the patient's use experience. In practical applications, the elastic pad and the support plate 230 are detachably connected, for example, by means of a buckle or a slot, or by means of Velcro. When an arc groove is provided on the top side of the support plate 230, the shape of the elastic pad also matches the shape of the arc groove, further improving the functionality during use.

[0039] When in use, the base plate 100 needs to be placed on a flat surface first, for example, the base plate 100 is placed on a hospital bed. In order to improve the stability of the base plate 100, an anti-slip pattern or a friction layer may be provided on the bottom side of the base plate 100. This makes the base plate 100 more stable when placed, preventing relative sliding between the base plate 100 and the hospital bed during use.

[0040] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
