[0027] The techniques, methods, and devices known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods, and devices should be considered as part of the specification.

[0028] As Figure 1 shown, an embodiment of an elbow joint restraint device includes: a first connecting part 1 and a second connecting part 2; the first connecting part 1 is used to connect the upper arm of a patient; the second connecting part 2 is used to connect the lower arm of a patient, one end of the second connecting part 2 is rotatably connected with one end of the first connecting part 1, and an angle limiting assembly is arranged at the rotation position; the second connecting part 2 includes a fixed part 20 and a movable part 21, and the movable part 21 is movably connected with the fixed part 20. The first connecting part 1 is connected with the upper arm of a patient, the second connecting part 2 is connected with the lower arm of a patient, and the angle limiting assembly is used to limit the movement of the elbow of the patient, so as to avoid the patient from performing the tube pulling operation, and effectively prevent the occurrence of unplanned extubation events; meanwhile, the second connecting part 2 includes the fixed part 20 and the movable part 21, the length of the movable part 21 relative to the fixed part 20 can be adjusted according to the body type of the patient, so as to match the body type of the patient, and good universality is achieved.

[0029] As Figure 1 shown, in some embodiments of the present application, one end of the first connecting part 1 is arranged in overlap with one end of the second connecting part 2, and is rotatably connected through a rotating shaft. In use, the second connecting part 2 is rotatable relative to one end of the first connecting part 1 through the rotating shaft, and synchronously rotates with the elbow of the patient.

[0030] As Figure 1 and Figure 2As shown in some embodiments of the utility model, the angle limiting assembly comprises a limiting groove 22 and a limiting column 10, the limiting groove 22 is arranged on the second connecting part 2, the limiting column 10 is arranged on the first connecting part 1 and passes through the limiting groove 22. When the second connecting part 2 rotates relative to one end of the first connecting part 1 through the rotating shaft, the limiting column 10 rotates along with the first connecting part 1 and moves in the limiting groove 22.

[0031] As Figure 1 and Figure 2 As shown in some embodiments of the utility model, the limiting groove 22 is arc-shaped and is provided with upper and lower limits corresponding to the rotating angle of the limiting column 10. The limiting groove 22 is arc-shaped to match the movement track of the limiting column 10 when the limiting column 10 rotates along with the first connecting part 1. Since the limiting column 10 moves in the limiting groove 22, when the limiting column 10 reaches both ends of the limiting groove 22, that is, reaches the upper limit or the lower limit, the limiting column 10 cannot continue to move, thereby limiting the second connecting part 2 to rotate relative to one end of the first connecting part 1 through the rotating shaft, limiting the elbow of the patient to move within a certain range, which has a certain degree of freedom and can avoid extubation.

[0032] In some embodiments of the utility model, the upper limit position and / or the lower limit position of the limiting groove 22 are provided with a limiting switch. When the limiting column 10 reaches the limit position, the limiting switch is triggered, and the limiting switch can also be replaced by other sensors.

[0033] In some embodiments of the utility model, the limiting switch is electrically connected with an alarm module. When the limiting column 10 reaches the limit position, the limiting switch is triggered and transmits an electrical signal to the alarm module, so that the alarm module alarms and prompts medical staff to pay attention. The alarm module can adopt the existing design scheme, which will not be described in detail here.

[0034] As Figure 3 As shown in some embodiments of the utility model, a plurality of mounting holes 11 are arranged on the first connecting part 1 to mount the limiting column 10. By mounting the limiting column 10 in the plurality of mounting holes 11, the rotation of the second connecting part 2 relative to one end of the first connecting part 1 through the rotating shaft can be further limited, and even the elbow movement of the patient can be completely restricted to avoid extubation.

[0035] As Figures 1 to 3As shown in some embodiments of the utility model, two groups of sliding grooves 200 are arranged on the fixing part 20 in parallel, a sliding block 210 is arranged on the movable part 21, and the sliding block 210 passes through one side of the sliding groove 200 and buckles the other side of the sliding groove 200. The movable part 21 moves on the sliding groove 200 through the sliding block 210, realizes the movement of the movable part 21 relative to the fixing part 20, and can be adjusted in length according to the length of the patient's forearm, so as to match the length of the patient's forearm, and has good versatility.

[0036] As Figure 1 and Figure 2 As shown in some embodiments of the utility model, a limiting hole 211 is arranged on the movable part 21, and the limiting hole 211 is used for screw connection adjusting nut. After the length adjustment of the movable part 21 relative to the fixing part 20 is completed, the adjusting nut is screwed into the limiting hole 211, one end of the adjusting nut abuts against the fixing part 20, and the position of the movable part 21 relative to the fixing part 20 is fixed and locked through friction.

[0037] As Figures 1 to 3 As shown in some embodiments of the utility model, a plurality of fixing strips 3 are arranged downwardly on the first connecting part 1 and / or the second connecting part 2 for installing the restraint belt, and the fixing strips 3 are arranged to be curved to the side of connecting the patient. A plurality of connecting holes can be arranged on the fixing strips 3 to facilitate the installation of the restraint belt, and the restraint belt is used for binding the patient's upper arm or forearm, so as to fix the elbow joint restrictor on the patient's body to restrict the elbow.

[0038] So far, the embodiments of the application have been described in detail. In order to avoid obscuring the concept of the application, some details known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein according to the above description.

[0039] Although some specific embodiments of the application have been described in detail through examples, those skilled in the art should understand that the above examples are only for illustration, not for limiting the scope of the application. Those skilled in the art should understand that the above embodiments can be modified or some technical features can be replaced equivalently without departing from the scope and spirit of the application.
