Description

Technical Field

[0001] The utility model relates to the field of medical tools, in particular to an arm restraint for protective restraint. Background Art

[0002] Protective restraint refers to a mandatory medical protection measure that is urgently implemented by medical staff during the psychiatric treatment process to maximize the restriction of the patient's behavioral activities in response to the special circumstances of the patient's condition. It is one of the methods of psychiatric treatment and care for such special patients, and its purpose is to minimize the harm to patients caused by other unexpected factors.

[0003] At present, the most common restraint for patients' arms is a restraint belt with Velcro connection characteristics. After the restraint belt is fixed to the arm, it is tied to the bed frame with a cloth belt to achieve fixation. However, in long-term practice, we found that this kind of restraint belt has a relatively simple function and only has a simple restraint function. When used, the limbs are completely pressed on the bed. When the arm needs to be raised to cooperate with the treatment operation, the staff can only put a cushion under the patient's arm, which is not only troublesome, but the addition of the cushion often leads to poor fixation of the patient's limbs. Summary of the invention

[0019] Combination Figure 1-4 A protective restraint arm restraint as shown, comprising Figure 1 The square base 1 shown in the figure is made of high-strength plastic, usually ABS or epoxy resin, etc., and has the characteristics of lightness, stability, high strength, etc. A top plate 2 is arranged above the base 1, and a restraint mechanism 3 for fixing the patient's arm is arranged on the top of the top plate 2. The top plate 2 is the mounting base of the restraint mechanism 3. In order to ensure the strength, the top plate 2 should usually have a certain thickness when plastic is selected, and should not be too thin. The top plate 2 serves as a mounting base on the one hand, and also as a hub for connecting with the fixed foundation (rails, bed frame, etc.) on the other hand.

[0020] In order to facilitate installation and operation, the top plate 2 is L-shaped, and a connection hole 4 is provided on the side of the L-shape, and is connected to the mounting clamp through the connection hole 4. When making a specific connection, the mounting clamp can be selected according to needs. The most commonly used mounting clamp is a connecting rod, one end of which is provided with a mounting plate and connected to the side of the top plate 2, and the other end is provided with a clamp for fixing to the railing or a plate clamp body fixed to the bed frame.

[0021] A special feature of the present invention is that a plurality of telescopic rods 5 are arranged between the base 1 and the top plate 2, and the height of the top plate 2 can be adjusted by the telescopic rods 5. The traditional method of placing a pillow under the restrained arm is abandoned, so that the bottom support of the restraint is better and less prone to large shaking. The telescopic rod 5 includes an outer sleeve 6 fixedly connected to the base 1, and a sliding rod 7 fixedly connected to the top plate 2. The sliding rod 7 is inserted into the outer sleeve 6 and forms a sliding fit with the outer sleeve 6. The relative sliding of the two forms the lifting of the top plate 2. Of course, after the adjustment is in place, the position of the top plate 2 needs to be locked. That is to say, the present invention also includes a locking mechanism, and the locking mechanism can lock the position between the top plate 2 and the base 1.

[0022] Regarding the specific form of the locking mechanism, it can be as shown in the figure: the locking mechanism includes a lifting locking bolt 8 arranged on the side wall of the outer sleeve 6, and the lifting locking bolt 8 and the outer sleeve 6 form a threaded fit. The inner end of the lifting locking bolt 8 presses against the sliding rod 7 to form a lock between the sliding rod 7 and the outer sleeve 6. By twisting the lifting locking bolt 8, the sliding rod 7 can be unlocked relative to the outer sleeve 6. The advantages are simple structure, lower overall cost, and easy promotion and popularization. Since the sliding rod 7 is tightened by the lifting locking bolt 8, in order to further improve the tightening degree, a better approach of the utility model can also be combined with Figure 5 and 2As shown in the figure, a rubber pressure head 9 is provided at the end of the lifting locking bolt 8, and the surface of the sliding rod 7 opposite to the lifting locking bolt 8 is a plane, and a locking tooth is provided on the plane. The rubber pressure head 9 on the lifting locking bolt 8 presses the locking tooth to form a lock. The locking tooth and the rubber pressure head 9 greatly enhance the friction force and ensure the tightness.

[0023] However, the disadvantage of the above scheme is that it is necessary to loosen multiple lifting locking bolts 8 to achieve adjustment. In order to further simplify the operation, the solution that can be adopted by the present invention can also be that the locking mechanism includes a threaded upright rod arranged at the bottom center of the top plate 2, and a threaded sleeve is arranged on the base 1 at the corresponding position of the threaded upright rod. The lower end of the threaded sleeve and the base 1 form a rotational fit through a rotary joint. The upper end of the threaded sleeve is sleeved outside the threaded upright rod and forms a threaded fit with the threaded upright rod. In other words, a lock is not separately provided at the telescopic rod 5, but by arranging a threaded upright rod and a threaded sleeve between the top plate 2 and the middle part of the base 1, the threaded sleeve can be rotated to drive the threaded upright rod to telescope relative to it, thereby forming height adjustment and self-locking. This method is more convenient to operate, but due to the need to install a threaded kit, the overall cost is higher. Each unit can choose according to actual usage.

[0024] Regarding the constraint mechanism 3 of the utility model, combined with Figure 1 and 2 As shown, the restraint mechanism 3 includes a semicircular elastic fixing card, and the inner surface of the elastic fixing card is provided with a cushion layer 10. The cushion layer 10 is made of thick cotton pads to ensure the comfort of contact. It also includes a Velcro strap 11 and a buckle 12 respectively arranged on both sides of the elastic fixing card, and the elastic fixing card is composed of two symmetrically arranged elastic sheets 13. When in use, the patient's arm is first placed in the elastic fixing card composed of two elastic sheets 13. Then, the Velcro strap 11 is passed through the buckle 12 and then fastened to its own surface, and the elastic fixing card is tightened. Since the elastic fixing card as a whole has both sufficient restraining strength and a certain degree of elasticity, it can ensure the covering of the arm.

[0025] Considering the comfort of the patient's forearm in the hand-raising restraint state, Figure 1 and 4As shown in , one end of the elastic fixing card of the utility model is also provided with an elastic arm support cloth 14, and a telescopic frame 15 is provided on one side of the base 1. The length of the telescopic frame 15 can be flexibly adjusted, so that the elastic arm support cloth 14 can effectively adjust the angle. Regarding the locking form of the telescopic frame 15, it can refer to the aforementioned telescopic rod 5. One end of the elastic arm support cloth 14 is fixedly connected to the cushion layer 10, and the other end is wound on the winding cross bar at the end of the telescopic frame 15. The winding cross bar can realize the winding and winding of the elastic arm support cloth 14 to obtain the required use length. Similarly, in order to achieve a certain support for the palm, a palm rest 16 is provided at the other end of the elastic fixing card.
