Description

Technical Field

[0001] The embodiment of the utility model relates to a bed, in particular to a restraint bed which can be applied to mentally ill patients. Background Art

[0002] A restraint bed is a bedding used to restrict the body or limb movements of patients (especially mentally ill patients) to prevent them from hurting themselves or others.

[0003] The patent document with the authorization announcement CN103445922B discloses a restraint bed for manic mental patients, which includes a bed body and a plurality of restraint and binding devices, which are mainly composed of a slide groove, a slider, an electric telescopic rod and a restraint belt. The technology related to the restraint belt is recorded in paragraph

[0019] of the specification: 3-4 holes are provided at the end of the lower half of the restraint belt, and the unlocking of the restraint belt is controlled by a spring switch matched with the holes. The spring switch is composed of a small pull rod and a spring sleeved in the middle of the small pull rod. When the small pull rod is pulled outward, the head of the small pull rod withdraws from the hole punched on the restraint belt, and the restraint belt is opened. The small pull rod is loosened, and the small pull rod rebounds under the elastic action of the internal spring, and the head is re-inserted into the hole of the restraint belt, so that the restraint belt can be locked.

[0022] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the technical solution of the present invention is further described in detail in a non-limiting manner in conjunction with the accompanying drawings and specific implementation methods.

[0023] The present embodiment discloses a restraint bed, which is mainly used to restrain patients with manic psychosis, and includes a bed body 1, two guide rails 2 and four restraint sleeves 3, wherein the bed body 1 is a basic structure for the patient to lie flat, the two guide rails 2 are fixedly installed on the bed body, and each guide rail 2 is connected to two restraint sleeves 3, and the four restraint sleeves 3 are respectively used to restrain the patient's limbs.

[0024] See Figure 1 In addition to the most basic iron bed frame and wooden bed board, the bed body 1 also includes three mattresses 10, which are arranged and laid on the bed board in a flush manner along the length direction of the bed board, with a gap of about 10 cm between adjacent mattresses 10, and three mattresses having two gaps. By setting the lengths of the three mattresses 10, the two gaps are respectively located at the middle and the end of the bed board, that is, when a person of normal height lies flat on the bed body in an upright posture, the two gaps are respectively located at the position of the forearm near the wrist and the position of the calf near the ankle joint of the human body.

[0025] The two guide rails 2 are respectively arranged in the gaps between the adjacent mattresses 10 and are fixedly connected to the iron bed frame by rivets, so that the two guide rails 2 are fixedly arranged in the middle and tail of the bed body 1. The two guide rails 2 have the same structure, and their two ends extend to the two sides of the bed body 1, and after extending to the edge, they have an arc-shaped 180° turn and turn into the lower side of the bed body 1. Figure 2 Each guide rail 2 is provided with a slide groove 20 on both sides thereof, and four restraint sleeves 3 are movably mounted on the guide rail 2 by matching with the slide groove 20. In order to prevent the restraint sleeve 3 from sliding out of the guide rail 2, a limit sleeve 21 is connected to the end of each guide rail 2 by a screw (not shown).

[0026] The structures of the four restraint sleeves 3 are the same, see Figure 3 Each constraint sleeve 3 includes a base 30 slidably connected to the guide rail 2, and a first constraint half ring 31 and a second constraint half ring 32 rotatably mounted on the base 30, and the first constraint half ring 31 and the second constraint half ring 32 also have a detachable connection relationship.

[0027] See Figure 5 , two pivot seats 300 are arranged on one side of the base 30, and a slot 301 is arranged on the opposite side. Slide bars 302 are arranged on the inner walls of both sides of the slot 301. The guide rail 2 can be inserted into the slot 301, and the slide bar 302 can be inserted into the slide groove 20. Under the action of the slide groove 302, the base 30 can slide on the guide rail 2 without falling off. A threaded hole 303 is arranged on the side of the base. When the base 30 is not needed to slide, a fixing pin (not shown) can be screwed into the threaded hole 303, and the fixing pin is pressed against the slide groove 20 to lock the base 30.

[0028] Since the base 30 can slide on the guide rail 2, when the restraint cover is needed, the entire restraint cover can be moved to the bed surface by sliding the base 30, and the position of the restraint cover can be adjusted according to the user's body shape. When the restraint cover is not needed, the entire restraint cover can be moved to the bottom of the bed by sliding the base 30, so that the bed surface can be kept clean and tidy, so that the restraint bed can be used for other purposes.

[0029] The lower end of the first restraining half ring 31 and the lower end of the second restraining half ring 32 are rotatably mounted on the two pivot seats 300 of the base 30 through hinges respectively. Due to the rotatable connection, there is a larger opening between the first restraining half ring 31 and the second restraining half ring 32 for the patient's hands and feet to be placed.

[0030] See Figure 3 A plug piece 310 is extended from the upper end of the first constraint semi-ring 31 , and racks 311 are provided on both sides of the plug piece 310 . The teeth of the rack 311 are in the shape of a right triangle, with the hypotenuse facing the second constraint semi-ring 32 .

[0031] See Figure 3 and Figure 6 The upper end of the second restraining half ring 32 is provided with a slot 320 for inserting the inserting piece 310, and receiving grooves 321 are provided on both sides of the slot 320. A locking assembly that is detachably engaged with the rack 311 is provided in each receiving groove 321. Each locking assembly includes a buckle 322, a connecting shaft 323 and a first spring 324. Figure 7The buckle 322 is further divided into a tooth portion 100, a barrel portion 101 and a handle portion 102; wherein the tooth portion 100 is provided with a latching tooth which is detachably engaged with the rack 311, and the shape of the latching tooth is a right triangle, with the right angle side facing the first constraint semi-ring 31; the barrel portion 101 is located between the tooth portion 100 and the handle portion 102, and is rotatably connected to the connecting shaft 323, and the connecting shaft 323 is fixedly arranged in the receiving groove, and the buckle 322 can rotate around the connecting shaft 323; the handle portion 102 can extend from the receiving groove 321, one end of the first spring 324 abuts against the receiving groove 321, and the other end abuts against the handle portion 102, and the first spring 324 is a compression spring, that is, the first spring 324 applies an outward elastic force to the handle portion 102.

[0032] The working principle of the locking assembly is as follows: the first spring 324 applies an outward elastic force to the handle 102, and under the action of the lever, the tooth 100 has a tendency to move into the slot 320, so the tooth 100 clasps the rack 311, and the first constraint half ring 31 is locked. When the handle 102 is pressed down and the pressure is greater than the elastic force, the handle 102 moves down, and under the action of the lever, the tooth 100 moves up and disengages from the rack 311, the insert 310 can move freely, and the first constraint half ring 31 and the second constraint half ring 32 can be disconnected.

[0033] In order to quickly disengage the first constraint half ring 31 and the second constraint half ring 32, a second spring 325 is fixedly arranged at the bottom of the slot 320. The second spring 325 is a compression spring. When the insert 310 is inserted into the slot 320, the second spring 325 can abut against the insert 310 and be compressed and deformed. When the tooth portion 100 is engaged with the rack 311, since the insert 310 has a thrust to move outward, the tooth portion 100 and the rack 311 are more tightly engaged, and the locking effect is better. When the tooth portion 100 is disengaged from the rack 311, the second spring 325 pushes the insert 310 to move outward quickly, so that the first constraint half ring 31 and the second constraint half ring 32 are quickly disengaged.

[0034] When using the restraint bed of this embodiment, the four restraint sleeves 3 are moved to the bed surface and the spacing is adjusted. The patient is controlled to lie flat on the bed, and the limbs are placed in the restraint sleeves respectively. The first restraint semi-ring 31 is inserted into the second restraint semi-ring 32. The locking and loosening are completed through the locking assembly, realizing "quick installation" and "quick removal". The patient's hands and feet can be restrained and loosened relatively quickly, thereby improving efficiency.

[0035] To protect the patient's hands and feet from being worn out, see Figure 4 The first constraint semi-ring 31 and the second constraint semi-ring 32 include, from the inside to the outside, a semicircular hard arc plate 40, a sponge 41 wrapped around the arc plate, and a canvas 42 wrapped around the sponge.

[0036] It should be pointed out that the above preferred embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
