Description

Technical Field

[0001] The invention relates to the technical field of human body restraint belts, in particular to a bed-fall prevention restraint belt with full freedom on a plane. Background Art

[0002] Due to the particularity of their illness, psychiatric patients often have severe mood swings and impulsive behaviors. When these patients lie in bed to rest, they may fall out of bed due to emotional loss of control or involuntary behavior, which increases the complexity and risk of nursing work. Therefore, in order to ensure the safety of psychiatric patients, anti-fall bed restraint facilities are very necessary.

[0003] Existing anti-fall bed restraint facilities are generally in the form of bedside guardrails or restraint belts. The bedside guardrail form is not ideal for restraining psychiatric patients because these patients often try to cross the guardrail or directly perform destructive operations on the guardrail when they are emotionally excited, causing the guardrail to fail. Therefore, in actual applications, human restraint belts are more commonly used.

[0004] Traditional restraint belts are mostly fixed in design: the chest belt is tied to the patient's chest and abdomen, and then connected to the fastener through a soft belt (the fastener is generally fixed on the mattress); although this type of design can effectively prevent falling out of bed and getting up, and is suitable for nighttime sleep, in actual application, we found that it also has certain shortcomings, such as: The fixed-design restraint belt will seriously limit the patient's freedom to turn over. Although the extension of the soft belt can allow the patient to turn over sideways, it cannot make the patient lie prone, let alone turn over a second or multiple times. In short, although the existing restraint belt can prevent the patient from falling out of bed and getting up, its degree of freedom on the plane is poor, and the patient cannot turn over freely. This kind of restraint may not only cause physical discomfort to the patient, but also easily cause psychological resistance and anxiety, affecting the nursing effect. Summary of the invention

[0005] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a fall-prevention bed restraint belt with full freedom on a plane, which has the advantages of full freedom on a plane and the patient being able to turn over freely.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1: See also Figure 1-Figure 5 , a fall-proof bed restraint belt with full freedom on a plane, comprising a chest belt 1 for wrapping around the chest and abdomen of a human body, such as Figure 1 As shown, a tensioning belt 2 is provided at one end of the chest strap 1, and a through slot 3 is provided at the other end for the tensioning belt 2 to pass through. After the tensioning belt 2 passes through the through slot 3, it is bent in the reverse direction and then bonded and fixed to the body or the outer peripheral wall of the chest strap 1, so that the chest strap 1 can be wrapped and fixed on the chest and abdomen of the human body.

[0023] In this embodiment, two tensioning straps 2 are provided, two through slots 3 are also provided, and an embedding slot 4 is provided along the outer peripheral wall at the middle position of the chest strap 1; like Figure 1 and Figure 5 As shown, a rubber strip 5 is fixed in the embedded groove 4. Specifically, the rubber strip 5 is cylindrical and has a circular cross section. The inner side of the rubber strip 5 is fixed to the inner circumferential wall of the embedded groove 4. The two ends of the rubber strip 5 are connected by a transition strip 14, thereby forming an annular rail that acts as a track. In this embodiment, there is a sleeve 11 for sliding on the annular rail. Figure 3 and Figure 4 As shown, a slot 12 is provided on the clamping sleeve 11 for allowing the connection area between the rubber strip 5 and the embedding groove 4 to pass through, so that the clamping sleeve 11 can move freely along the annular track to generate a "constraint point"; In the present invention, the chest strap 1 is tied to the chest and abdomen of the human body, the annular rail on the chest strap 1 is connected to the sleeve 11, the sleeve 11 is arranged on the mat 6, and the mat 6 is laid and fixed on the bed along the width direction of the bed. Through the design of the annular rail and the sliding sleeve 11, the patient's getting up and falling out of bed are restricted, and the restraint point is allowed to slide freely on the annular rail, thereby allowing the patient to freely turn over or lie prone on the bed surface for an unlimited number of times, which significantly improves the patient's freedom of movement.

[0024] The method of fixing the mat 6 on the bed can be set by technicians in this field according to actual needs. For example, straps can be set at both ends of the mat 6 along the length direction, and then the straps can be tied to the bed frame, or they can be wrapped around the bed and connected at the bottom of the bed to locate the position of the mat 6.

[0025] Embodiment 2: See also Figure 2-Figure 4 , based on the first embodiment, in this embodiment, as Figure 2 As shown, a transverse groove 7 is provided on the mat 6, and a fixing rope 8 is provided in the transverse groove 7. Both ends of the fixing rope 8 are fixedly connected to the inner wall of the transverse groove 7, and the fixing rope 8 plays the role of a "track"; In this embodiment, a sliding member is provided at the bottom of the clamping sleeve 11, and the sliding member is slidably sleeved on the fixing rope 8. Specifically, Figure 3 As shown, the sliding member is a sliding sleeve 9, and a sliding groove 10 is provided on the sliding sleeve 9 for allowing the fixing rope 8 to pass through. The sliding sleeve 9 can slide freely on the fixing rope 8. In addition, the clamping sleeve 11 is fixedly connected to the top of the sliding sleeve 9. The free movement of the clamping sleeve 11 on the fixing rope 8 further expands the sliding range of the restraint belt, making the patient's movement on the bed more flexible.

[0026] In the present invention, the sliding sleeve 9 can be made of nylon cloth, which is wear-resistant and not easy to break; and the clamping sleeve 11 is made of a non-deformable material, such as iron, to prevent it from falling off the rubber strip 5; the rubber strip 5 is preferably made of high-hardness silicone rubber or polyurethane, which can be bent into an annular rail and avoid deformation due to extrusion by the clamping sleeve 11, thereby preventing the clamping sleeve 11 from falling off.

[0027] Embodiment three: See also Figure 5-Figure 8 Based on the first or second embodiment, this embodiment specifically provides a transfer bar 14 structure, such as Figure 6 As shown, both ends of the rubber strip 5 are provided with a tapered portion, which extends to form a plug post 13, and both ends of the adapter strip 14 are recessed with a recessed portion, which forms a connecting tube 15. The connecting tube 15 is used for allowing the plug post 13 to be inserted, thereby completing the connection. After the plug post 13 is inserted into the connecting tube 15, the diameter of the entire annular rail is uniform, which facilitates the movement of the ferrule 11 thereon.

[0028] See also Figure 7 Two sets of positioning teeth 16 are symmetrically arranged on the outer peripheral wall of the plug post 13, and two entry grooves 17 are formed between the two sets of positioning teeth 16. Two sets of bite teeth 18 are symmetrically arranged on the inner wall of the connecting tube 15. The two sets of bite teeth 18 can enter along the two entry grooves 17, and after the transfer strip 14 and the connecting tube 15 rotate, they bite with the positioning teeth 16 to form Figure 8 In the state shown, the engagement of the engagement teeth 18 and the positioning teeth 16 can play a role of locking and preventing from falling off, and stably connect the two ends of the rubber strip 5; In this embodiment, the cross-sections of the engaging teeth 18 and the positioning teeth 16 are both triangular and face oppositely, which can effectively lock and prevent them from falling off. The two are tightly engaged with each other and have a large friction force, thereby preventing the connecting tube 15 from rotating on the plug post 13 to a certain extent.

[0029] like Figure 7 As shown, the end protrusion of the connecting tube 15 is formed with a positioning protrusion 19, and the end depression of the rubber strip 5 is formed with a positioning groove 20 for the positioning protrusion 19 to be inserted into. When the engaging teeth 18 are engaged with the positioning teeth 16, the positioning protrusion 19 is also inserted into the positioning groove 20, thereby further playing an anti-rotation role and preventing the connection from loosening.

[0030] In actual use, by replacing the adapter strip 14 with different sizes (lengths), it can be suitable for patients with different body shapes.

[0031] 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.
