[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model provides two technical solutions:

[0030] Figure 1 , Figure 2 , Figure 4 and Figure 5 The first embodiment is shown: a funnel-shaped protective wrist collar for preventing unplanned extubation, comprising:

[0031] The wrist part 1 is mounted on the patient's wrist;

[0032] The palm portion 2 is covered on the outside of the patient's palm and is integrally connected to the wrist portion 1;

[0033] The wrist portion 1 is cylindrical, the palm portion 2 is funnel-shaped, and the wrist portion 1 and the palm portion 2 are processed from the same transparent plastic sheet, and the two ends of the transparent plastic sheet are connected by a connecting structure to form a ring-shaped wrist portion 1 and palm portion 2. The cylindrical wrist portion 1 can cover the wrist well, while the funnel-shaped palm portion 2 can fully expose the palm for easy observation and ventilation, and the edges of the wrist portion 1 and the palm portion 2 are flexibly covered.

[0034] The connection structure is two pieces of Velcro 6 disposed at both ends of the transparent plastic sheet, and the two pieces of Velcro 6 are arranged in a wide and a narrow manner, and the calibers of the wrist 1 and the palm 2 can be adjusted by adjusting the pasting positions of the narrow Velcro 6 and the wide Velcro 6. Velcro has a long service life, is not easy to deform, has strong tensile resistance, and has excellent ductility (ductility means that the calibers of the wrist 1 and the palm 2 can be extended by adjusting the pasting positions).

[0035] The soft protection structure 3 is arranged inside the wrist 1, and contacts the patient's wrist flexibly to avoid hurting the patient's skin when being pulled; the soft protection structure 3 is a gel jelly pad attached to the inner side of the wrist 1. The gel jelly pad is directly wiped and disinfected with disinfectant after each use.

[0036] The binding structure 4 is wrapped around the outside of the wrist 1 and binds the wrist 1 to the bed guard to restrain the patient's hand; the binding structure 4 is a flat, wide and long rope, and the two sections of the flat, wide and long rope are locked by a duckbill clip after passing around the wrist. Compared with a thin rope, the flat, wide and long rope is wrapped around the outside of the wrist 1, and its force is dispersed, which causes less damage to the patient's wrist when pulled, and the wrapping binding can also withstand a large pulling force. The use of a duckbill clip for locking also makes the binding more convenient.

[0037] The limiting structure 5 is arranged outside the wrist 1 for the binding structure 4 to pass through so as to position the binding structure 4; the limiting structure 5 is an arched piece arranged on both sides of the wrist 1, and a gap is formed between the arched piece and the wrist 1 for the binding structure 4 to pass through. The limiting structure 5 can position the binding structure 4, keep the binding structure 4 from being separated from the wrist 1, and thus maintain its normal use;

[0038] The force measuring structure 7 is arranged at the middle position of the limiting structure 7 near the wrist 1, and is used to detect the force when the binding structure is pulled by the wrist 1; the force measuring structure 7 is a pressure sensor, and the wire of the pressure sensor runs through the outside of the binding structure 4 and is connected to the display. The pressure sensor is provided with a normal force measuring threshold range, and no alarm is given for the pulling force detected during normal arm lifting, and an alarm is given when the pulling force is too large and exceeds the threshold.

[0039] Figure 3 A second embodiment is shown, which mainly differs from the first embodiment in that the binding structure 4 is a belt, a belt buckle is provided at one end of the belt, and a section near the other end is evenly provided with lock holes adapted to the belt buckle.

[0040] Using a belt instead of a flat, wide, long rope and a duckbill clip is not only convenient for adjusting the tightness, but also can withstand greater pulling force. Either of the two binding structures 4 can be selected, or other similar binding parts can be used.

[0041] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0042] When in use, the unfolded wrist part 1 and palm part 2 are put on the outside of the wrist and palm, the wrist part 1 is adjusted to wrap the wrist, and then the sides of the wrist part 1 and the palm part 2 are attached together using the Velcro 6;

[0043] When binding is required, the joint side of the wrist portion 1 and the palm portion 2 is oriented toward the bed guard, and then the binding structure 4 is passed through the limiting structure 5, and then the binding structure 4 is tied to the bed guard.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
